Let me float an idea 25. February 2008 William Davis (0) I'd like to float an idea. The Track Your Plaque program is a fee-for-membership website. We chose this method of covering our costs--website development, graphics, software coding, etc.--since we do not accept advertising. I do believe that not having any advertising on our website has kept us impartial and unbiased--we mean what we say and not because we are selling something. But there's a downside to assessing a membership fee: It limits the number of people who are willing or able to access the information. It also limits the dissemination of these concepts, due to such phenomena as limited content exposure to internet search engines.
Actos, Avandia, and vitamin D 22. February 2008 William Davis (16) Up until a few years ago, if a patient showed signs of the metabolic syndrome/pre-diabetes, or early diabetes, I would often prescribe one of the drugs, Actos (pioglitazone) or Avandia (rosiglitazone), known as the thiazolidinediones, or TZD's for short. Although I do not manage diabetes, I was witnessing a flood of patients with pre-diabetic patterns that inhibited correction of lipoprotein patterns. So I saw the TZD's as a means of potentially assisting with correction of these abnormalities. My rationale back then was that many people with metabolic syndrome struggled to raise HDL cholesterol, reduce triglycerides, reduce small LDL, reduce the inflammatory measure c-reactive protein (CRP), as well as reduce blood sugars towards the normal range. The TZD's partially corrected these phenomena. But over the last 2 1/2 years, I haven't written a single prescription for these agents since I've added vitamin D to the regimen. Vitamin D in my experience in the Track Your Plaque approach:--Raises HDL--far more than the TZD's ever did. --Reduces small LDL--Reduces triglycerides--Reduces c-reactive protein--Reduces blood pressure--Reduces blood sugarIn other words, vitamin D appears to not only reproduce many of the effects of the TZD's, but exceeds the effects. The effects are often so wonderful that I've taken many people off their TZD's. Vitamin D, of course, also provides numerous benefits for bone health, reduction of cancer risk, and other health benefits that the TZD's simply cannot compete with. Vitamin D also lacks the quite substantial side-effects of TZD's: water retention and weight gain (around 8 lbs in the first year of treatment), possible increase in risk for heart attack (Avandia), definite increased likelihood of congestive heart failure in those prone to it. How about cost? Actos goes for about $2 per pill (30 mg tablet). Vitamin D in the gelcap form (the only form we use) costs around $0.05 per capsule--5 cents. That's a 40-fold difference in price for what I would regard as an inferior--substantially inferior--product. Throw into the mix a dramatic reduction or elimination of wheat products and other high-glycemic index foods, and all the phenomena of the metabolic syndrome and its associated lipoprotein patterns show even more improvement or full reversal. In fact, with this approach we are seeing record-setting magnitudes of correction of these parameters every day. Getting HDL, for instance, into the 60 mg/dl or 70 mg/dl range has never been so easy.
What if heart scans become obsolete? 19. February 2008 William Davis (3) What will we do if or when CT heart scans become outdated and something better comes along?Heart scans are, after all, our principal tool for detection and precise quantification of coronary atherosclerotic plaque. They provide the basis for the Track Your Plaque program: serial heart scans to track progression or regression of coronary plaque. So what the heck will we do if heart scans become obsolete, if some other technology proves superior for precise lengthwise quantification of coronary plaque?Simple: Then we will convert to that measure. Say, for instance, that in 5 years, MRI advances to the point where it is quick and precise, despite the rapid motion of the heart that has, in past, caused this technology to stumble for plaque quantification. Instead of obtaining a heart scan score of, say, 350, instead an MRI might yield information like:Calcium volume: 350 cubic mmSoft plaque elements: 200 cubic mmFibrous tissue: 700 cubic mmIn other words, while a CT heart scan provides a calcium score that serves as a surrogate measure of total plaque volume, perhaps the next wave of technology will directly measure total plaque volume. Don't CT coronary angiograms already measure total plaque volume?No, they definitely do not. At present, the best they can do is visualize the non-calcific elements and suggest the diameter reduction created by plaque at a specific point. Thus, results like "50% blockage in the mid-left anterior descending." What they do not provide is a lengthwise total volume of plaque and all its elements. Perhaps some software manipulation in future will yield such information (and I think it will, though I personally have been unable to accomplish it). So neither the Track Your Plaque program nor the Heart Scan Blog are necessarily bound to heart scans. But heart scans, in 2008, remain the number one best tool for plaque quantification that is easy, precise, available, and inexpensive. For those reasons, CT heart scans continue to serve as the basis for these programs, and not CT angiograms, MRI, or other non-quantitative technology.
Scare tactics 19. February 2008 William Davis (17) Does the media engage in scare tactics?Read the headlines in local newspapers, and you'd believe that your friends and neighbors are dropping like flies, all victims of heart attacks.I occasionally peruse the headlines run in newspapers and magazines around the U.S. by subscribing to a feed service through Google. For the phrase, "heart attack," you can get a sample of what is being said around the country about people having heart attacks.What continues to impress me is just how far off a truly constructive and helpful message the media provides every day. Not only are they guilty of delivering a flawed message, they also favor headlines and stories that scare the heck out of people. "This could happen to you!"Is it just the quest for headlines that grab readers' attentions? Is there some complicity with the medical systems that pay significant advertising revenues for their heart disease programs and hospitals?I doubt such complicity exists to any substantial degree. But the fact remains: Every day across the U.S., the media does an effective job of scaring the heck out of the public--enough for you to run to your doctor or hospital to find out if you, too, could fall victim to heart disease. A stress test, perhaps heart catheterization, three stents or bypass often results.In effect, these headlines make great hospital PR, an inducement that flushes out the patient highly motivated to pursue further costly heart testing--whether or not it's needed. A sampling:Stress test could help prevent sudden heart attackDAWN ZERA Times Leader CorrespondentBob Schultz, 67, was feeling a persistent pain in his back, which he was pretty sure was caused by working on a deck for his son’s home.But after the deck was finished, the pain was still there.“It was nagging, but not enough to hurt,” Schultz said.He visited his primary care physician, thinking maybe some muscle relaxants would be prescribed. The doctor sent him to a clinic in Tunkhannock to do a complete body CAT scan, and then had Schultz do a stress test. The on-site cardiac stress testing at a Geisinger Medical Group office in Tunkhannock showed that things did not look good: Schultz had a blockage. He was scheduled for a cardiac catheterization.It was a surprise; a heart problem had not even crossed Schultz’s mind as a possible cause of his back pain.“I had good cholesterol, have been the same weight for years, and had excellent blood pressure,” Schultz said.He went for the catheterization at Geisinger Wyoming Valley, and there doctors discovered Schultz’s condition was even more serious. He had three blockages – 99 percent, 95 percent and between 80 and 90 percent.“It shocked the living daylights out of everyone. It was surreal,” Schultz said.The catheterization turned into open heart surgery that very same day.The surgery was on a Tuesday, and he was home by Sunday. He never even had time to fully think about having the operation. And he had never experienced the typical warning signs of a heart problem, such as chest pain or shortness of breath.“The doctors said I had the worst alarm system they’d ever seen,” Schultz said. “They probably saved my life, with me not knowing I had a problem.”It also made him think about his brother, who had had been in good health but suddenly died in his 40s of a suspected heart attack.“We never had any heart problems in our family, so we never believed it. But now I think, geez, it probably was true,” Schultz said.His experience has served as a cautionary tale for friends and family. Just this past month, a friend specifically requested a stress test for himself.“It sets off alarms in your circle. People think ‘if it can happen to him, it could happen to me,’ ” Schultz said. “It triggered people to think about what could happen to them.”Firefighter Saves Heart-Attack Victim on D.C. CourtABC NewsA 30-year-old man suffered a heart attack while playing basketball on a D.C. court.That's when a Brian Long's firefighter training kicked into action. The 25-year-old D.C. firefighter's team had just finished their pick-up league game Friday evening at Lafayette Elementary School's basketball court when the man stumble to the ground."He ran a few feet and collapsed again so I turned him over and I looked at him his eyes rolled back and he just stopped breathing," Long said.Long began performing chest compressions and soon he was joined by Anthony Gadson, a pharmaceutical sales representative, who learned CPR years ago and starting assisting with mouth to mouth resuscitation."If that were me, somebody would've done the same thing for me, so I feel like I did what I was supposed to do," Gadson explained.While Long and Gadson worked to keep the victim's heart going, all the players and spectators, including teammate and league commissioner Bob Johnson, gathered around the lifesaving effort."We gathered in a circle and one of the wives of one of the players just led us in this huge prayer," said Johnson."It makes me feel great," Long told ABC 7/NewsChannel 8. "I am just glad that I am a D.C. Firefighter."Free Drugs After Heart Attack Would Save Money, Lengthen LivesMore patients would take recommended medications, study saysBy Ed EdelsonMONDAY, Feb. 18 (HealthDay News) -- Eliminating the cost of medications for people who have heart attacks would lead to longer lives and lower overall medical costs, new research suggests."These are highly effective medications that are relatively inexpensive, and the events they are designed to prevent are extremely expensive," said study author Dr. Niteesh K. Choudhry, a researcher in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women's Hospital in Boston and an assistant professor at Harvard Medical School. His report is published in the Feb. 19 issue of Circulation.The study covered four drugs commonly prescribed after heart attacks -- aspirin, beta blockers, ACE inhibitors or angiotensin receptor blockers (ARBs), and statins. Use of those drugs is relatively low under the current system, in which people share the cost with Medicare or other health insurance plans, Choudhry said. For example, only 46 percent of people take beta blockers after heart attacks, and only 50 percent take cholesterol-lowering statins. Less than 20 percent of heart patients used all four of the medications, according to the study.The model set up by Choudhry and his colleagues doesn't assume a major increase in compliance with prescriptions, because "cost is just one reason why patients do not take medications," he said, adding that relying on previous studies of drug cost and use, the model assumes an increase of about 14 percent, with perhaps 64 percent of people taking the medicines if they were free.The result would be an increase in average survival after a heart attack, from the present 8.21 quality-adjusted life years to 8.56 years. "That is small in an absolute sense, but in an aggregate sense, it is very large," Choudhry said.And medical costs over a lifetime would go down, from the current $114,000 to $111,600, the study added."This study adds to a growing body of research showing how important it is to reduce or eliminate patient co-payment for drugs," said Robert M. Hayes, president of the Medicare Rights Center in New York. "Medicare should take the lead in forging the creation of drug coverage that allows patients to get the medications their doctors consider vital.""It certainly makes sense from the medical point of view," said Dr. Richard A. Stein, a professor of medicine at New York University. "Studies have shown that giving even middle-income people free drugs improves outcome. The greatest benefit will go to people in the lower socioeconomic and immigrant population."But the study is theoretical, Stein noted. "One would like to see some real-world trial to determine whether this works in fact, whether providing free drugs without co-payment would make a difference, he said.Such a study has begun at Harvard, Choudhry noted. His group is working with a major health insurer, not Medicare, in a trial that assigns some people to get medications without cost, while others will get the standard co-payment."It will take several years for us to get answers," Choudhry said. But similar investigations are being started by other medical insurers and corporations, he added.The idea is potentially applicable to some other chronic conditions, such as congestive heart failure and diabetes, Choudhry noted. And, if the use of recommended medications after a heart attack goes up more than predicted by the model, "the cost savings would be phenomenal," he said.More informationTo learn about how to stay on your statins, consult the National Heart, Lung, and Blood Institute.Heart Attack Threatens Young, OldBAKERSFIELD, Calif. -- Nearly 1.2 million men and women suffer a heart attack every year in the United States, according to the American Heart Association. However, not all of the victims are old.Brian Connell considers himself a lucky guy. At the age of 39, he's physically active, he has a high-level job, and he is also a heart attack survivor. "I know I was overweight and obviously had some other risk factors against me," said Connell. "I wish I did more to prevent it, certainly."Connell is doing plenty of things now. He met with a nutritionist and changed his diet. He gets regular exercise and takes medication to control his cholesterol. He also gets regular checkups.Click here to find out more!Cardiologist Jeffrey Popma said it's not unusual to see younger heart attack patients. "We have dozens of patients in our system every year who have been under 40 years old who have suffered a major heart attack," said Dr. Popma.Popma said getting medical help quickly is the key to survival. Connell said that is what made all the difference for him. And when people ask him if that was his first heart attack, Connell said he is quick to tell them it was his last heart attack.Copyright 2008 by TurnTo23.com.

Which statin is best? 17. February 2008 William Davis (6) The statin drugs can indeed play a role in a program of coronary plaque control and regression. However, thanks to the overwhelming marketing (and lobbying and legislative) clout of the drug manufacturing industry, they play an undeserved, oversized role. I get reminded of this whenever I'm pressed to answer the question: "Which statin drug is best?"In trying to answer this question, we encounter several difficulties:1) The data nearly all use statins drugs by themselves, as so-called monotherapy. Other than the standard diet--you know, the American Heart Association diet, the one that causes heart disease--it is a statin drug alone that has been studied in the dozens of major trials "validating" statin drug use. The repeated failure of statin drugs to eliminate heart disease and associated events like heart attack keeps being answered by the "lower is better" argument, i.e., if 70% of heart attacks destined to occur still take place, then reduce LDL even further. This is an absurd argument that inevitably encounters a wall of limited effects. 2) The great bulk of clinical data examining both the incidence of cardiovascular events as well as plaque progression or regression have all been sponsored by the drug's manufacturer. It has been well-documnted that, when a drug manufacturer sponsors a trial, the outcome is highly likely to be in favor of that drug. Imagine Ford sponsors a $30 million study to prove that their cars are more reliable and safer. What is the likelihood that the outcome will be in favor of the competition? Very unlikely. Such is human nature. If we were to accept the clinical trial data at face value and ignore the above issues, then I would come to the conclusion that we should be using Crestor at a dose of 40 mg per day, since that was the regimen used in the ASTEROID Trial that achieved modest reversal of coronary atherosclerotic plaque by intravascular ultrasound. But I do not advocate such an ASTEROID-like approach for several reasons:1) In my experience, nobody can tolerate 40 mg of Crestor for more than few weeks, a few months at most. Show me someone who can survive and tolerate Crestor 40 mg per day and I'll show you somebody who survived a 40 foot fall off his roof--sure, it happens, but it's a fluke. 2) The notion that only one drug is necessary to regress this disease is, in my view, absurd. It ignores issues like hypertension, metabolic syndrome, inflammatory phenomena, lipoprotein(a), post-prandial (after-eating) phenomena, LDL particle size, triglycerides, etc. You mean that Crestor 40 mg per day, or other high-intensity statin monotherapy should be enough to overcome all of these patterns and provide maximal potential for coronary plaque reversal? No way. 3) Plaque reversal can occur without a statin agent. While statin drugs may provide some advantage in the reduction of LDL, much of the benefit ends there. All of the other dozens of causes of coronary atherosclerotic plaque need to be addressed. So which statin is best? This question is evidence of the brainwashing that has seized the public and my colleagues. The question is not which statin is best. The question should be: What steps do I take to maximize my chances of reversing coronary atherosclerotic plaque? The answer may or may not involve a statin drug, regardless of the subtle differences among them.Copyright 2008 William Davis, MD
Lipoprotein(a)--neglected and unappreciated 16. February 2008 William Davis (2) Lipoprotein(a), or just Lp(a) to its close friends and neighbors, is among the most underappreciated and neglected of causes of coronary plaque. It's the Rodney Dangerfield of lipoproteins. Lp(a) rarely gets diagnosed before people come to my office. They've often been through the ringer: doctors have thrown their hands up in frustration because of poor response to "standard" treatment (AKA statin drugs); the patient doesn't understand why they might be thin and active yet have the high blood pressure of someone 70 lbs heavier; they have heart disease despite wonderful cholesterol values. One blood test and the answer becomes clear: They have Lp(a). It explains all these phenomena. They why don't more physicians order this simple test? Why don't we hear more about this prevalent (1 in 5 people with coronary plaque have it) genetic pattern that accelerates risk for heart disease?There are a number of reasons. But I believe the most powerful reason is simply that there is no big revenue-generating drug to treat it. Statins reduce LDL cholesterol to the tune of $27 billion dollars a year (2007 revenue). There's no such blockbuster for Lp(a). Of course, Niaspan represents the relatively anemic attempt to commercialize a pharmaceutical treatment for Lp(a), but side-effects and the lack of FDA trials for the Lp(a)-reducing indication have stalled its commercial success. (Efforts to block the flush with various products, by the way, may re-invigorate niacin as a pharmaceutical agent. The drug companies smell money here.)Another reason for Lp(a)'s unpopularity: Though there are mounds of data that document--without question--that Lp(a) is an important risk for coronary disease and other forms of atherosclerotic disease, we lack treatment trials. For instance, niacin vs. placebo for 5 years, then count the number of heart attacks and deaths. We have numerous, repetitive, overlapping, redundant trials with statins adhering to this design. We have none for niacin and the treatment of Lp(a). Niacin is also a pain in the neck for your doctor. He/she rapidly tires of the calls about the crazy and disconcerting flushing with niacin. Most are unaware that proper hydration reduces or eliminates the flush for the majority of people. It takes too much time and energy to educate people. (By the way, prescription Niaspan makes no mention of purposeful hydration. They only suggest the nonsensical "Take with a low-fat snack," i.e., snacks that actually counter the therpaeutic effects of niacin. What they should be saying is "take with a high-fat snack" like raw almonds, foods that facilatate the benefits of niacin.)Should someone concoct a successful pharmaceutical treatment for Lp(a), it will make the news, headlines in health magazines and health sections of the newspaper will blare about how important Lp(a) is. Yet it has been there all along, frustrating people and their physicians. In the Track Your Plaque experience, Lp(a) clearly 1) correlates with heart scan scores, 2) correlates with progression of heart scan scores without treatment, and 3) poses special challenges for treatment. Interestingly, some of our biggest failures have been with Lp(a), as well as some of our biggest successes. (Our current record holder for the largest percentage reduction in heart scan score has Lp(a).) If you have coronary plaque, or if there is family risk of heart disease, then Lp(a), in my view, is an absolutely essential factor to test for. Yes, treatment poses challenges. But once you know who your enemy is, then you can focus your efforts on it. Not knowing whether or not you have it leaves your efforts unfocused and generally flawed.

Wheat-free and still fat 15. February 2008 William Davis (14) Readers of The Heart Scan Blog know that I preach a diet that contains foods with low glycemic index to control weight, raise HDL, and reduce triglycerides, blood sugar, and small LDL. A crucial aspect of a low glycemic index approach is to sharply reduce, preferably eliminate, wheat products. I pick on wheat specifically because it has come to dominate the American diet. Look at the shelves in the supermarket: aisle after aisle of processed wheat products. The bread shelves alone in some of the grocery stores in my neighborhood are 40 feet long, six shelves high. There's also breakfast cereals, granola products, cookies, cakes, baking products, pretzels, crackers, pasta, and on and on. Wheat products like these are tasty and they're addicting--literally. Test animals given processed wheat will eat more and gain more weight. Wheat fails to trigger satiety. So laboratory mice--and you and I--eat and eat, because eating wheat stimulates appetite, creates a hunger for more wheat, and a vicious cycle ensues. Eliminating wheat, on the other hand, results in dramatic drop in appetite, substantial weight loss, followed by correction of the metabolic disruptions it created. A quick Google search for "gluten-free" turns up a startling array of wheat-free, gluten-free, yet high glycemic index products. The breakfast cereal pictured, for instance, can do as much damage as most wheat containing products--though it won't cause gluten enteropathy (also known as "celiac disease"). The product shown contains:Brown rice flakes, rice bran, evaporated cane juice, brown rice syrup, raisins, cinnamon, gum arabic, vanilla, molasses, ground flaxseed, rosemary extract.A 1/2-cup serving contains: Total Carbohydrate 31g Dietary Fiber 5g Sugars 8gAnd I'll bet that most people eat a lot more than a half-cup serving. But you and I are not laboratory mice. If deprived of wheat, many people will then seek out processed rice products (rice cakes, Rice Krispies), processed cornstarch or cornmeal products (tacos, cornbread, many processed foods using these products for texture or thickness), or other products labeled "gluten-free." Going wheat-free for our purposes is not about avoiding the gluten in wheat. It is about seizing control of appetite, eliminating a food that disrupts insulin responses, reduces HDL, raises triglycerides, and creates small LDL particles. But this applies to processed corn, rice, and other high glycemic index foods, as well. So, occasionally, someone will declare, "I've eliminated wheat! Now I only eat rice, corn, and I've discovered all the gluten-free alternatives!" Unfortunately, they've traded one evil for another. So it's not just about wheat. It's really about reducing or minimizing foods that mess up metabolic responses and lead to coronary plaque growth. Wheat is the biggest culprit and so I focus on it. However, you could easily transfer far less popular rice and corn products into center stage and allow them to wreak all the health damage of wheat. Going wheat-free for our atherosclerotic plaque-control purposes is not the same as going gluten-free. So be careful of the distinction. Wheat-free gummi bears:Contents:Organic dehydrated cane juice, organic corn malt syrup, organic juice concentrates (may contain organic apple, organic apricot, organic aronia, organic carrot, organic cranberry, organic elderberry, organic lemon or organic red beet), organic spinach powder, organic apple pectin, citric acid, natural fruit flavors. Virtually pure sugar--yet wheat-free. Wheat-free rice breadIngredients:White rice flour, water, honey, soy oil, natural gum, salt, yeast, natural gumCopyright 2008 William Davis, MD
Heart disease is reversible 13. February 2008 William Davis (10) In a previous post, Take this survey: I double-dare you, I posed a challenge:Ask your doctor: Is heart disease reversible? Their answer:1) No. Heart disease is definitely not reversible. 2) Yes, in rare instances, like lightning striking twice. 3) Yes, of course it is! Let's talk about how to do it!I predicted that few readers of this blog would respond. I also predicted that the few who did would respond with the first answer, Heart disease is definitely not reversible. After all, in nearly all medical practices, the only parameters routinely followed to track risk for heart disease are LDL cholesterol and blood pressure. A measure of the disease itself (i.e., coronary atherosclerotic plaque) is not followed. So how can your doctor actually tell whether heart disease is reversed or not? When I engage in this conversation with colleagues, it goes no farther than rolled eyes or a snort. In my experience, talking about reversal of heart disease is a wasted effort. To my great surprise, this simple survey received a total of 177 responses. Even more surprising, 122 (69%) of respondents chose number 3, claiming that their doctor said that heart disease is reversible. Overall results:1--31 responses (17.5%)2--24 responses (13.5%)3--122 responses (69%) Now wait a minute: Where is the disconnect? Why are doctors saying that heart disease is reversible, yet not following this concept in practice? Contrary to the survey results, I have yet to meet a patient who said their doctor was trying to reverse their heart disease. Of course, this may be a skewed population, but I find it hard to believe that the prevailing view is that heart disease is reversible. Anyway, this simple survey cannot settle the why or how, nor can it suggest just how prevalent this opinion is. I am encouraged by these results. If true, it means that the message that heart disease is a reversible process is spreading. It may be make-believe heart disease reversal as preached by Dr. Dean Ornish or claimed by statin drug manufacturers. It may be the hocus-pocus of practices like chelation, or scams like nattokinase. But perhaps the seed of this notion has been planted in the minds of the medical community.I'd be interested in hearing from the respondents who reported that their doctor said heart disease is reversible. How exactly are they going about achieving reversal?
Looking for health in all the wrong places 12. February 2008 William Davis (11) The American public now has unprecedented freedom to explore new directions in health. Never before have we had the enormous resources now available to add to our health experience: nutritional supplements, endless books on health and diet, the internet, online discussion groups, insurance products to permit spending on self-directed health services like medical savings accounts and flex-spending. The Track Your Plaque program is just one facet of this emerging and exciting area of self-empowerment in health. Compare what you can achieve with such a program with the situation of just 25 years ago, when the most you might get to reduce your risk for heart disease was to take the (largely ineffective) drug cholestyramine, probucol, and a low-cholesterol, low-fat diet. Unfortunately, it also means that people have unrestrained potential to be tripped up, to be misled down some dead end of health that fails to accomplish desired goals, maybe even dangerous. The more freedom we have, the greater the choices, the more room we have to screw up. Among the unproductive strategies I've witnessed recently:--Nattokinase--The staying power of this scam continues to shock me. There is no rational basis for its use. A woman today declared that she would like to stop the warfarin that she was taking to prevent stroke from atrial fibrillation by taking nattokinase. This would be a mistake that could cost her a major and disabling, even fatal, stroke. Though warfarin is far from perfect, it at least achieves its goal of reducing stroke risk. Nattokinase does not. Nattokinase does nothing but make money for the people who sell it. --Poly-nutritional supplements. You've heard of polypharmacy, the phenomenon of taking numerous medications with overlapping effects and side-effects, usually because of multiple doctors, each prescribing drugs without knowledge or interest in what colleagues are prescribing. I'm seeing the same phenomenon with supplements: 20,30, or more supplements per day, all in the hopes of heightening health. A focused few supplements is, in my view, superior to a shotgun approach of trying to improve health by taking hawthorne, silymarin, chrysin, calcium, Chinese herbs, and 25 other supplements. --Chelation--Based on the notion that heavy metal toxicity causes heart disease; removal of heavy metals cures it. I've read some of the books on chelation, in addition to the slim scientific data, to decide whether there was anything to it. In my view, it is a complete and utter scam. It does make money for its practitioners, however. That's not to say that heavy-metal chelation doesn't have a role in health--it does. But it serves no purpose in coronary disease prevention and control. --Colonic purges--Achieved by a number of routes, some oral, others via enema. Promotions for purging are often accompanied by a pile of scum that apparently lined somebody's intestinal tract. Purges purportedly, well, purge it from the intestine. This is also plain nonsense. There is no such toxic scum lining anybody's intestinal tract. However, if calorie restriction or a fast results inadvertently from the effort, perhaps some good comes from it. --Statin drug alternatives--The unprecedented $27 billion dollar a year success of the statin drug industry, accompanied by the enormous marketing push by their manufacturers, has spawned an entire industry of statin alternatives. They range from red yeast rice, to guggulipid, to various concoctions of sterol esters, Chinese herbs, chitosan, and a variety of others. Some actually do reduce cholesterol a few points. Preparations like red yeast rice even pose a side-effect profile not too different from the prescription statin agents. Unfortunately, even among those agents that work, the effects tend to be small to trivial. While I am no lover of statin drugs nor the statin drug industry, I find these preparations to be anemic imitators. You'd be better off with raw nuts and ground flaxseed than wasting your money on these cheap imitations. --Worries about liver toxicity--A day doesn't go by that I don't have at least several questions about suffering toxic liver effects from niacin, vitamin D, statin drugs, etc. I have treated thousands of patients for heart disease in its various stages and forms and have used many different strategies. How many times have I seen serious liver toxicity? A handful of times and usually from either mis-use of the agent or drug, or in a person with several other coexisting diseases. (Other serious health conditions, like kidney failure, raise the toxicity of drugs and supplements.) Liver toxicity in the vast majority of otherwise healthy people is close to being a non-concern. Readers of The Heart Scan Blog and of the Track Your Plaque website know that I celebrate expansion of knowledge and information access to the public. However, I am concerned that the flip side of this growing self-empowerment is expanding potential for mistakes. It reminds me of an attorney friend, who, when diagnosed with prostate cancer, explored all manner of alternative treatments, from laetrile to heavy metal chelation to high-dose lycopene tablets. At the initial stage of diagnosis, his cancer was readily treatable. He now has widely metastatic cancer. Maintain an open mind, but think before you commit to some crazed claim of cure, some "secret" to health, somebody's brazen but concealed attempt at steering profits in their direction.

February 2008 William Davis (7) I'm posting this intriguing comment from the Track Your Plaque Member Forum because I would like to speak to the Member who posted it.The Member said:I tested at 965 last year, and while I have followed the TYP diet and nutraceutical recommendations, I was totally unprepared for my first repeat scan (at the same lab/machine) on January 29, 2008. My result was 4.0, and at first I assumed the rating scale had been changed.I then noted that 3 of the big four arteries received scores of 0, which means the same in any scale, and that four nodules had disappeared from the scan field.Wow!!If this is true, it would represent the biggest success in the Track Your Plaque program--ever! It would be an incredible story to tell, to convince the public and medical community that it is indeed possible, and a cause for popping a bottle of champagne! It would also represent what I would regard as essentially a cure for coronary atherosclerosis, a virtual elimination. While we have plenty of success in stopping the progression or reducing heart scan scores, we do not have 100% success. I wish we did. The Track Your Plaque program is, to some degree, a work in progress. We learn from experiences, continually adjust to obtain the results we desire. Even as it stands today, the Track Your Plaque program is superior to any program of heart disease prevention known--by a long stretch. But it's not infallible, it's not foolproof. That's all the more reason I would like to communicate with the Track Your Plaque Member who posted this comment. I would also like permission to view the heart scans themselves. (I can't obtain them nor view them without the individual's permission.) While we often have difficulty judging reversal just by looking at heart scans, presumed reversal to this profound degree should be obvious, even to the naked eye.I would like to know--in detail--precisely what steps were taken and whether there was anything unique about this person's medical Cureality | Real People Seeking Real Cures Toggle navigation Home Blog Home Archive Join Now Log in How old are you? 17. October 2009 William Davis (21) George walks into my office. I ask him his age. "I'm 21 years old," he declares. Yet I look at George. He's got gray thinning hair, his posture is slumped forward rather than erect, the flesh on his upper arms hangs loosely, he's got wrinkles on his hands and face, brown spots on the back of his hands and arms. He looks more like 70 years old to me. "I don't think you're 21 years old. I think you're 70.""Prove it," he says.Okay. What now? Minus any formal identification like a driver's license, how do I prove that George is really 70-something and not 20-something? Not an easy thing, when you think about it. If George were a tree, I'd cut him down and count his rings. Is there such a phenomenon in humans? This is actually a fascinating area of research, looking for reliable biomarkers of aging. Among the most quantitative markers of aging is telomere length. Telomeres were once dismissed as nonsense sequences in DNA. However, more recent thought among geneticists is that telomeres shorten with aging and provide the body's cells a timeline of aging. This way, George's cells act like they are 70, not 13, and don't start producing gobs of growth hormone and testosterone in preparation for puberty. What can slow or stall the shortening of telomere length? There are two I'm aware of:1) Caloric deprivation--i.e., taking in fewer calories. This was among the theories explored by Dr. Roy Walford during his Biosphere2 experience, based on his work in mice that showed that caloric deprivation nearly doubled lifespan. 2) Vitamin D--Richards et al (2007) found that, the higher the vitamin D, the longer the telomere length. The highest vitamin D levels conferred a 5-year effective difference in telomere length. So, if I could look inside George's cells and count his telomeres, I could judge with confidence whether he was 21 or 70. Or, he could take vitamin D sufficient to increase blood levels to a healthy range and be more like 65. No high blood pressure 14. October 2009 William Davis (20) Primitive cultures that were, until recently, unexposed to the modern world, reveal some important insights into blood pressure. The Yanomamo of South American, the Xingu Indians of Brazil, rural Kenyans, and the natives of Papua, New Guinea have average blood pressures of 103/63 mmHg. Even more incredibly, while 90% of modern Americans will develop high blood pressure as they age, the members of these primitive cultures do not develop age-related hypertension. What's the secret? Perhaps the full "secret" of their remarkably low blood pressure has not been fully unraveled, but several observations have emerged:--They are not exposed to modern processed foods like pretzels, crackers, and breakfast cereals. --Low-carbohydrate foods. Carbohydrates are largely the product of the food industry, convenience foods bought in stores. No such thing in the jungle. --Living outdoors, having to forage and hunt, walk to your destination, not drive or wait in line for food. --Outdoor lives, wearing little more than a few strands of clothing, exposes you to plentiful vitamin D activation from sunlight exposure.--Consuming wild game, rich in omega-3 fatty acids, enhances endothelial health and reduces blood pressure. --Wild plants, roots, and berries, as well as wild game, along the coast, are richer in iodine. The studies examining the habits of the Yanomamo and other primitive cultures focused principally on sodium intake. Indeed, the very low sodium intake of primitive cultures was associated with lower blood pressure--up to 6 mmHg reduction. But there's clearly more to learn than "cut your salt." Name that food 13. October 2009 William Davis (30) What common food can:• Cause destructive intestinal damage that, if unrecognized, can lead to disability and death? • Increase blood sugar higher and faster than table sugar?• Trigger an autoimmune inflammatory condition in the thyroid (Hashimoto’s thyroiditis)? • Create intestinal bloating, cramps, and alternating diarrhea and constipation, often labeled irritable bowel syndrome? • Trigger schizophrenia in susceptible individuals? • Cause behavioral outbursts in children with autism?• Cause various inflammatory diseases such as rheumatoid arthritis, ulcerative colitis, dermatitis herpetiformis, systemic lupus, pancreatic destruction, and increase measures of inflammation like c-reactive protein?• Cause unexplained anemia, mood swings, fatigue, fibromyalgia, eczema, and osteoporosis?The food is wheat. Yes, the ubiquitous grain we are urged to eat more and more of by the USDA (8-11 servings per day, according to the USDA food pyramid), American Heart Association, American Dietetic Association, and the American Diabetes Association. Wheat is among the most destructive ingredients in the modern diet, worse than sugar, worse than high-fructose corn syrup, worse than any fat. What other common food can result in such an extensive list of diseases, even death?Celiac disease alone, a severe intestinal inflammatory condition from wheat gluten, affects an estimated 3 million Americans (Celiac Disease Foundation). The medical literature is filled with case reports of deaths from this disease, often after many years of struggle with incapacitating intestinal dysfunction and the sufferer's last days plagued by encephalopathy (brain inflammation). What happens when you remove wheat from the diet? The majority of people quickly shed 20-30 lbs in the first few weeks, selectively lost from the abdomen (what I call “wheat belly”); blood sugar plummets; triglycerides drop up to several hundred milligrams, HDL increases, LDL drops (yes, wheat elimination is a means of achieving marked reduction in LDL cholesterol, especially the small, heart disease-causing variety); c-reactive protein plummets. In addition to this, intestinal complaints improve or disappear, rashes improve, inflammatory conditions like rheumatoid arthritis improve, diabetes can improve or be cured, and behavioral disorders and mood improve.Along with the ill-fated low-fat dietary advice of the last 40 years, the advice to eat plenty of "healthy whole grains" is responsible for untold disease and suffering. Yes, if you start with a fast food and junk diet and replace some of the calories with whole grains, you will be better off. (That was the logic--the Nutritional Syllogism--of the studies that established the benefits of whole grains over processed, "white" grains.) But eliminate wheat grains and health takes a huge leap forward. And, no, there is no such thing as wheat deficiency--B vitamins, insoluble fiber, some protein--can easily be replaced by other foods. Heart Defects Simplified 12. October 2009 William Davis (0) For as long as I've known him, echocardiography technologist, Ken Heiden, has had a deep fascination with congenital heart disease. Ken has just written a wonderful book on congenital heart disease called Heart Defects Simplified. While this is a bit off-topic for the Heart Scan Blog, I know that there is a serious lack of helpful information for people with congenital heart disease and parents of children with congenital heart defects. So I asked Ken to tell us something about his book. WD: I've reviewed your book and have been thoroughly impressed with the clarity and detail with which you handle a complicated topic. You somehow manage to make it easy to grasp, far more than any other resource I've used in past. Do you feel that your book serves a previously unmet need? KH: This book serves an unmet need in that it presents the complex subject of congenital heart defects in a simplified manner. Most books on this subject are anywhere from 300-1700 pages in length and tend to be written for doctors. Further, most of these books have very few diagrams, and they rely upon their explanations to describe these defects. Heart Defects Simplified is 104 pages in length, describes the most common defects, including surgical repairs, in a two-page format with full-color diagrams on the left and complete descriptions on the right of each chapter. The book is particularly written for sonographers, nurses and parents, but it is valuable for anyone interested in this subject. It is particularly useful in clinical situations because it is convenient to lay out at your side with a coil-bound format and durable pages. Further, there are appendixes which include "Surgical Procedures in Alphabetical Order," "Prevalence of Congenital Heart Disease," "Scanning Protocols for Echocardiographers," "Imaging Tips," a glossary and a worksheet for echocardiographers. WD: I know that many people with loved ones who have congenital heart defects, particularly parents of children with such conditions, are often kept in the dark about the details of the condition. Is your book suitable for the non-technical reader, such as parents? KH: This book is an excellent resource for parents. It is written in language that is understandable by parents as well as technologists and nurses. The full-color diagrams provide invaluable insight into this very complex world. Most importantly, this book attempts to make the subject of congenital heart defects accessible to anyone who wishes to comprehend this subject. WD: I understand that people with congenital heart defects and parents are active participants in online discussion groups. Will your book serve as a resource for people who participate in these groups? KH: This book is not only a resource for sonographers and parents, but the book is accompanied by a blog (HeartDefectsforEveryone.blogspot.com) that attempts to address many of the concerns commonly encountered with congenital heart defects. This blog is a work in progress, but I hope to provide a forum for parents, healthcare personnel, and others to share their questions and concerns about congenital heart disease. My experience with the omega-3 index 8. October 2009 William Davis (23) I just got back my own results from the Gene Smart laboratory reporting my omega-3 index and omega-6:omega-3 ratio. My results:Omega-3 index: 8.2%Omega-6:omega-3 index: 3.2 to 1Not too bad, but not as good as I'd expected. Hmmm. Although the omega-3 index of 8.2% puts me in the lower risk category for sudden cardiac death, I was hoping for a level of 10% or slightly greater, the level that I believe is more likely to be related to plaque inactivation or reversal. I obtained this level of omega-3 averaging an intake of EPA and DHA of about 2500 mg per day. I was somewhat disappointed by the omega-6:omega-3 index. Although it's clearly better than the American average range of 20:1, it is short of the ideal of 2:1 or even 1:1. Since I purposely avoid omega-6-rich sources like corn oil, vegetable oils, sunflower or safflower oils, I wonder if I've overdone the nuts. The two ways to improve the omega-6:omega-3 ratio are to 1) decrease omega-6, or 2) increase omega-3. I'm going to do both. So I thought I was doing pretty well. But there's clearly room for improvement.Remember: If just reduction of cardiovascular risk is your interest, then a lackadaisical attitude towards these issues might work. But if your interest is elimination of risk and reversal of atherosclerotic plaque, then it pays to go the extra mile. In this case, knowing your omega-3 index and omega-6:omega-3 ratio might tighten up your program. The Omega-3 Index: The higher, the better? 6. October 2009 William Davis (26) So you take a few fish oil capsules every day and eat fish once or twice a week. What is the blood and tissue level of omega-3 fatty acids generated by your habits? A number of variables enter into the equation. For instance, if you take fish oil capsules, what is the concentration of omega-3 fatty acids? How well are they absorbed? After absorption, how effectively are omega-3 fatty acids incorporated into cell membranes?Even if you take fish oil supplements, it is hard to know just how much you’ve increased blood levels. It is now possible to measure the amount of omega-3 fatty acids in your bloodstream, a value called the omega-3 index. Too little and you might still be at high risk for cardiovascular events. The Omega-3 index and sudden cardiac deathTwo large studies have demonstrated that higher omega-3 blood (the level in red blood cells, or RBCs) levels were associated with reduced likelihood of sudden cardiac death. The risk for sudden cardiac death was 10-fold higher for the lowest omega-3 RBC levels compared to the highest.Harris WS 2008; adapted from Siscovick DS et al 1995 and Albert CM et al 2002(The omega-3 Index was derived from whole blood omega-3 levels, which correlate with RBC omega-3 levels, and are thus “estimated.”)What’s the average omega-3 RBC level for Americans? Most Americans have omega-3 RBC levels in the 2.5-4.0% range, consistent with the tallest bars at the left and associated with greatest risk for sudden cardiac death. People with heart disease can have levels less than 1%. Some authorities propose that this new measure be called the omega-3 index. Subsequent studies have shown that the omega-3 index has greater power to discriminate who will have a heart attack or die from sudden cardiac death better than any other common laboratory measure of coronary risk, including LDL cholesterol, HDL cholesterol, triglycerides, total cholesterol to HDL ratio, homocysteine, and c-reactive protein.Just as hemoglobin A1c offers a 3-month look into blood glucose levels, the omega-3 index reflects your long-term omega-3 intake. The quantity of RBC omega-3s also closely parallels the quantity of omega-3s in heart tissues.What is an ideal omega-3 index?The above studies relating RBC omega-3 levels and sudden cardiac death suggest that a level of 6.3-7.3% is associated with far fewer fatal events?but events are not eliminated at this level. Is there even greater benefit with levels higher than 6.3-7.3%?A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks. This suggests that even higher levels are necessary to prevent non-fatal events. Should we target 10%? 12%? Maybe higher? Any higher and we are toeing the level achieved by the Inuits, the “Eskimoes” of Greenland, northern Canada and Alaska who have been observed to have a low rate of heart disease.What’s your omega-3 index?The appreciation of the importance of omega-3 fatty acids marks one of the greatest health revelations of the last 50 years. We can now measure it.The ability to measure the proportion of omega-3 fatty acids in red blood cells may provide yet another means for all of us to further reduce risk for cardiovascular events.If you are interested in knowing your omega-3 index, we are now making the fingerstick test kits available by going here. Vitamin D increased my cholesterol 2. October 2009 William Davis (38) A friend told me this story. Her friend, Linda, had added vitamin D to her daily supplements. Because she'd had a vitamin D blood level of 22 ng/ml, she was taking 6000 units per day. However, Linda also had a high cholesterol value with a total cholesterol of 231 mg/dl. After several months on the vitamin D, she had another cholesterol panel. Total cholesterol: 256 mg/dl. "It must have been the vitamin D! So I stopped it right away." Is this true? Does vitamin D raise the level of blood cholesterol? Yes, it does. But it's a good thing. Let me explain. Followers of The Heart Scan Blog know that total cholesterol is really a mix of 3 other factors:Total cholesterol = LDL cholesterol + HDL cholesterol + triglycerides/5This is the Friedewald equation, still used today in over 95% of cholesterol panels. So, by the Friedewald equation, anything that increases LDL, HDL, or triglycerides will increase total cholesterol. One of the spectacular changes that develops over a year of taking vitamin D is that HDL cholesterol skyrockets. While sensitivity to this effect varies (probably on a genetic basis), HDL increases of 10, 20, even 30 mg/dl are common. A starting HDL, for instance, of 45 mg/dl can jump up to 65 or 70 mg/dl, though the effect requires up to a year, sometimes longer. Vitamin D can also reduce triglycerides, though the effect is relatively small, usually no more than 20 mg/dl or so. Likewise, the effect on LDL is minor, with a modest reduction in the small type of LDL. So the dominant effect of vitamin D from a cholesterol standpoint is a substantial increase in HDL. Looking at the equation, you can see that an increase in HDL is accompanied by a commensurate increase in total cholesterol. If HDL goes up 25 mg/dl, total cholesterol goes up 25 mg/dl. So Linda is absolutely correct: Vitamin D increases cholesterol--but it's a good thing that reduces risk for heart disease and is an important part of a coronary plaque-reversal program. This is yet another reason why I advocate elimination of total cholesterol on lipid panels. There is no useful information in the total cholersterol value, only the potential for misinformation. Nutrtional ignorance is not unique to the U.S. 28. September 2009 William Davis (20) Heart Scan Blog reader from Australia, Michaela, also a mother of a son with a complex congenital heart defect, wrote this series of e-mails to me. (Published with Michaela's permission.) I've been reading the article, Valve disease and Vitamin D from April '07, by Dr William Davis. I'm hoping you may have some information on the topic. I'm hoping someone will have time to help me. I have been supplementing my 15 year old son with Vit D for 4 months but only 1000 (U) per day. I would like to increase the dosage but am not sure if I would do him more harm than good. I have been researching vitamins and supplements on the net for a few months and have been amazed at what I have found. I only wish I had done it years ago. My son has been let down by the Australian Medical Profession and it's a race against time now to keep him well and avoid a heart transplant. My son was born with aortic stenosis and had a valvotomy at 4 weeks of age. This damaged the aortic valve and he had a Ross Repair procedure at aged 3. This left him with a damaged heart muscle and leaking aortic & pulmonary valves. In May '08, his heart grew more enlarged, causing the mitral & tricuspid valves to also leak. I took him to Bangkok in Feb this year where he had 70 million of his own Adult Stem Cells directly injected into his heart muscle with the hope of strengthening the muscle and eventually valve replacement. My son has recovered from the surgery and is once again symptom-free, thanks to the wonderful advice followed by the Author & Cardiologist, Stephen T. Sinatra. I have followed his supplement regime and what a difference! Of course, this won't last while my son's valves continue to leak. My son has also developed secondary hyperparathyroidism, bone thinning and hypothyrodism. Vit D & Calcium have something to do with this I believe. My Australian Doctors have never made mention of any vitamins or supplements .... EVER! Transplant is all they will consider and we are not having it. If you have any info or links to any sites which may be useful to me, could you email them to me? I would be grateful for any help I could get. SincerelyMichaelaI responded to Michaela's e-mail:Hi, Michaela-- Vitamin D is extremely important. Sometimes, hyperparathyroidism and calcium derangements are caused by vitamin D deficiency. You might be able to get help with this from an endocrinologist, since they are the ones who deal with hyperparathyroidism. An endocrinologist might even be familiar with several recent studies that document this phenomenon:Vitamin D therapy in patients with primary hyperparathyroidism and hypovitaminosis DVitamin D deficiency and primary hyperparathyroidismAlso, see the discussions at www.vitamindcouncil.org from Dr. John Cannell.Because of the complexity of your son's health, it might be hazardous to stray too far away from conventional care though you and I know that there are limitations to that perspective. For that reason, I would urge you to press for answers from a knowledgeable endocrinologist. I hope you find the answers you need. William Davis, MDSeveral months later, Michaela provided this update:Hi Dr Davis, I wrote to you back in July regarding my 15 year old son's need for a Heart Transplant through a failed Ross Repair and the possible Vitamin D connection. You sent me some valuable links and I thank you again for that. I just wanted to let you know, I think you have given me the answers. I increased Lee's Vitamin D supplement to 6000U a day and, along with the recommended nutritional supplements of US Cardiologist Dr Stephen T Sinatra, there have been remarkable improvements! Lee also had 70 million of his own Adult Stem Cells injected into his heart in February. As we know, Stem Cell Therapy takes time and Lee was looking like time was quickly running out. I have removed him from the transplant list. He is now reading normal Kidney function, the BNP (Brain Natriuretic Peptide, a measure of heart failure] has dropped by 7000 and his liver size has reduced to where it no longer causes him discomfort. The liver tests show it's still affected but it's function is improving each month. His last Echo was in early July and there had been a reduction in the size of his heart, which is so important. To the Doc's, Lee can't get better, there is only transplant or death so you can imagine the surprise on their faces to see him looking and feeling so well with their tests to back it up. Still, even though it's staring them in the face, they don't want to know about it. They have no interest in what supplements he is on or Stem Cell therapy. God help their other patients. I view them in the waiting room and think of them as lambs to the slaughter. We are not spoiled for choice with Doc's here in Western Australia. I have to take what I can get and there is not many who would take on Lee's case. He was number 1 on the transplant list and a most urgent case. Not many were willing to even look at him with his cardiac history and all I had to help was the arrogant Doc's at the Advanced Heart Failure Unit. They were not at all interested in his secondary hyperparathyroidism. I suppose it didn't matter what else he had compared to his heart problems. Anyway, I'm writing to thank you. Lee would be transplanted or dead now if it wasn't for Dr's like you sharing their knowledge online. I wish I had researched things years ago, Lee might not have sunk so low if I had. I don't know if the transplant can be held off indefinitely, but like I tell Lee, "Stay well. There are amazing people out there doing amazing things, if you can just hang on. The miracle is around the corner." He's so well, you'd have to see him to believe it. But I have 7 kids and Lee is as physically active and as well as the other 6! For how long he can stay like this, I don't know but if his ejection fraction [a measure of left ventricular strength] can keep climbing and his body gets stronger, I have hope for another attempt at valve replacement. I'm still shocked and angry that nutritional supplements have never been mentioned in the 15 years I've been dealing with cardiologists. Surely they know about them. I have read through dozens of reports online of the benefits of them--Why haven't they?! Thank God for the online Doc's such as yourself, the valuable info would never make it out of a Doctor's office in Western Australia! I've had to leave my country for Stem Cell therapy and then implore overseas Doc's for advice and information. What does that say for the Australian Medical Profession? Not a lot! They put him in the position he is in yet don't want to help get him out. I'm so very grateful to you, thank you and God bless. Michaela Note: The above is not meant to be an implicit endorsement of stem cell therapy. This was just part of Michaela's story about her son. Eat cranberries 24. September 2009 William Davis (17) Most people already know that cranberries are useful for preventing urinary tract infections. Cranberries can also be useful for preventing other sorts of infections, such as dental cavities and stomach ulcers because of cranberry's ability to block bacterial adhesion. Cranberries can also be a useful component of a heart healthy program. Several unique properties of cranberries contribute to various aspects of heart health:• Cranberries are a rich source of pectin--Pectin is a soluble fiber, the sort that binds bile acids in the intestinal tract and naturally reduces LDL cholesterol.• Cranberries are a rich source of polyphenols and flavonoids--Including the wonderfully fascinating anthocyanins, the flavonoids that confer the beautiful red color. Surprisingly, cranberries are richer in polyphenols and flavonoids than blueberries, strawberries, and grapes. Cranberry juice is also rich in these compounds. However, beware of cranberry juice "cocktail," which is diluted with other liquids such as high-fructose corn syrup. Like grapes, cranberries are a source of resveratrol, the polyphenol also found in red wines that some believe is responsible for reduced risk for heart disease and extending life. • Cranberries have high antioxidant activity--Cranberries are among the highest in antioxidant capacity against superoxide radicals, hydrogen peroxide, and hydroxyl radicals, oxidizing factors believed to underlie heart disease, cancer, and aging. Cranberries also reduce the oxidation of LDL cholesterol particles. • Cranberries block uric acid production--Cranberries have the unique ability to block the activity of an enzyme, xanthine oxidase, that converts xanthine to uric acid. Uric acid is believed to add to heart disease risk and is the factor responsible for gout. • Cranberries increase HDL cholesterol--Cranberry juice increases HDL by 3-4 mg/dl. Cranberries are only modest sources of sugars, with 7.19 grams “net” carbohydrates (total carbohydrates minus fiber content) per cup of whole raw cranberries. The best way to eat cranberries is to consume the real thing: eat the whole berry, as in sugar-free cranberry sauce or added to baked dishes like chicken. Second best are dried cranberries. However, be careful of the overly-sweetened dried cranberries that contain added sugar (for a total of 78 grams sugar per cup--far too much). Unsweetened dried cranberries can be purchased, or you can dry them yourself.Cranberry juice is another way to obtain the health benefits of cranberries; the unsweetened juice, while quite tart, is the best with 30.5 grams sugar per 8 oz--so don't drink more than 4 oz at a time. The more common cranberry juice “cocktails” are generally too sugary and/or too dilute for full health benefit. The cranberry harvest season in Wisconsin, Michigan, Oregon, Massachusetts, and New Jersey is just getting underway, so we should be seeing fresh cranberries on store shelves or farmers' markets any day now. Procedures 'R Us 23. September 2009 William Davis (20) Kay came to the office for an opinion. Over the past 8 months, she'd received a stent to the left anterior descending coronary artery and, during a separate procedure, a stent to the left subclavian artery. "My cardiologist was very capable doing procedures. But when I asked, 'What do I do now?' he barely said a word and handed me a presciption for Crestor." This kind of incredible neglect is the norm: Write a prescription for statin drug, delegate dietary advice to the hospital dietitian who advocates a heart disease-causing low-fat diet, followed by hospital discharge. You are expected to report any recurrent symptoms (which are inevitable), at which point you might "qualify" for another procedure. It would be malpractice if it were not the prevailing standard in the community. Yes, the prevailing standard is neglect--neglect to identify, quantify, and correct all the identifiable causes of heart disease; neglect to discuss the nutritional methods that actually correct the abnormal patterns that cause heart disease; neglect to discuss nutritional supplements or medications beyond statins that further reduce heart disease risk and "need" for more procedures. In other words, the prevailing community standard is to stent, bypass, prescribe statin. It is not to understand why the disease occurred in the first place, correct the causes and minimize or eliminate any future danger or need for procedures. I see consultation after consultation involving stories just like Kay's. People are frightened and they sense intuitively that nobody raised the question of why they have a potentially fatal disease. Don't allow yourself to fall victim to this incredibly neglectful mode of practice, the one that has enriched hospitals, the drug industry, many cardiologists, but does little to address the actual disease. << Older posts Newer posts >> Newer posts12...353637383940414243...123124Older posts Toggle navigation Home Blog Home Archive Join Now Log in An exercise in optimism 5. May 2007 William Davis (0) Followers of the Track Your Plaque program already know that maintaining an optimistic viewpoint is important in gaining control over coronary plaque. In fact, I believe that, in many cases, a sense of optimism may make or break your CT heart scan score-reducing efforts. Pessimists rarely drop their score, while optimists do so all the time. This week posed a challenge to my optimism. I spent the last week on jury duty hearing the details of a murder case. For four days, I listened to blow-by-blow testimony about the totally pointless, unprovoked death of a young man by a drug-dealing thug. Much of the witness testimony was from people who shared the hopeless, violent world of the defendant. I was, however, completely impressed by the dedication of the prosecuting attorney, a 50-some year old man who was clearly deeply dedicated to his mission and didn't once provide any indication that he was grandstanding or looking for some personal glory. He was doing his job and trying to obtain justice for the fallen victim. I was equally impressed by the judge, who seemed unfazed by the events but carefully explained why the system worked the way it did. After the trial, he provided some further insights to us jury members and I saw him as a human being who, like the prosecutor, was trying to make a small contribution to making the world better. Though many of the witnesses who testified against the defendant shared his world, I was impressed with their courage in coming forward. They face the threat of reprisals, I'm sure, for coming forward to the law and testifying against a known career criminal. Several of them said that they were not after any reward, but simply wished to do the right thing and provide testimony that proved damning against the defendant. I acted as the jury foreman and I was proud of how the jury members listened carefully, asked intelligent and probing questions, and then helped us render a confident and expeditious sentence: guilty. If anything, despite the tragic circumstances, I was much heartened at how all the participants in this process played their part and justice (at least in the legal sense) was served. Let optimism prevail, even in dire circumstances. No need to re-invent the wheel 2. May 2007 William Davis (0) I seem to be repeating myself lately, but I think this does bear repeating:There's no need to re-invent the wheel when it comes to gaining control over your heart scan score.The Track Your Plaque program is the most powerful approach known to help you gain control over your coronary atherosclerotic plaque and CT heart scan score, bar none. While 100% of people do not drop their score, more and more people every week are doing so. (One of the admitted weaknesses of the Track Your Plaque website is our failure to list more success stories; we're working on it.)The basic program is quite simple:--The Rule of 60 for lipids (LDL 60 mg/dl; HDL 60 mg/dl or greater; triglycerides 60 mg/dl or less)--Identify hidden causes of plaque, esp. small LDL, Lp(a), and IDL, followed by specific corrective action--Fish oil--minimum 1200 mg per day of EPA + DHA--Normal vitamin D3 blood levels (We aim for 25-OH-vitamin D3 of 50-60 ng/ml)--Normal blood sugar (<100 mg/dl)--Normal blood pressure (<130/80)--An optimistic attitude Much of the other stuff--vitamin K, matrix metalloproteinase reducing strategies, flavonoid strategies, exercise-induced hypertension, etc.--are, for the majority, fluff. Their real role is in people who may have failed in stopping the rise of their heart scan score just doing the basics of the program. If you neglect the basics, hoping to find some magic potion, I'm afraid the overwhelming likelihood is that you will fail. I've seen it happen time and again. Someone will come to my office with an extraordinary list of supplements--hawthorne, dozens of anti-oxidants, EDTA, concentrated flavonoid preparations, and on and on. Not only is it shockingly expensive to do this, it's also unnecessary and foolhardy. This kind of unfocused, hocus-pocus in the hopes of getting it right fail time after time. The Track Your Plaque program, while not foolproof, is the best I know of. Stick to the basics and wander off when the basics fail. But there's extraordinary power in just achieving the basics. Are we a front for drug companies? 2. May 2007 William Davis (3) I was shocked recently when someone accused me and the Track Your Plaque website of being nothing more than a front for the drug industry, that we are promoting concepts with the hidden pharmacuetical agenda behind us. Don't make me laugh. How in the world that kind of impression could be gotten from either the Heart Scan Blog or the Track Your Plaque website is beyond me. But I occasionally do need to state explicity: We do not promote drugs, neither this Blog nor the Track Your Plaque website has ever sought nor been backed by pharmaceutical money. The only money that supports this website is our own and that from paying Track Your Plaque members. In fact, I am quite proud of the unbiased content and commentary on both venues. I challenge anyone to point out how and where there is any suggested relationship to a hidden source of commercial backing. I assure you, there is none. If I say a drug is worth you and your doctor considering, then I say so with a true belief in it, not because somebody or some company paid me to say so. If I say a drug stinks, I believe that too. If we use a specific supplement in the program, it's because we believe it truly adds value to a plaque-reversal program. We receive no money from drug, supplement, or other commercial interests to promote their products. Period. What is "normal"? 1. May 2007 William Davis (2) When it comes to laboratory values and medical testing, a common dilemma is knowing what is "normal." Let me explain. First of all, when you receive a laboratory result for a test, a "reference range" or "normal range" is usually provided. Where did that range come from? It varies from test to test. For instance, a low potassium is easy, because low potassium levels can lead to life threatening consequences, e.g., dangerous heart rhythms. High potassium likewise, because dangerous phenomena develop when potassium generally exceeds 5.5 mg/dl or so.But what about something like HDL or LDL. Here's where confusion reigns. Often, "normal" is obtained by taking the average and saying that any value plus or minus two standard deviations (remember that painful class?) represents normal or reference range. If that were true, what if we applied that principle to body weight. If we weighed several thousand adult women, the average would be in the neighborhood of 172 lbs (no kidding). Does that mean that 172 lbs plus or minus two standard deviations is normal? No, of course not. There is therefore a distinction between "normal" and "desirable". For HDL cholesterol, your laboratory report might say that an HDL cholesterol of 40-60 mg/dl is normal. But is it desirable? I don't think so. The most frequent HDL level for a male with a heart attack is 42 mg/dl--hardly desirable. Let's take triglycerides. The average triglyceride level in the U.S. is somewhere around 140 mg/dl. For those of us who do a lot of lipoprotein testing, we can tell you that triglycerides at this level, though generally regarded as being within the normal range, are associated with flagrant and obvious excesses of several abnormal lipoprotein particles that contribute to coronary plaque growth (VLDL and often IDL; small LDL; drop in HDL and shift towards small HDL).So, always take the so-called "normal" or "reference" values on a lab report as crude guidelines that often have little or nothing to do with health or desirability. Unfortunately, many physicians are not aware of this and will declare any value within the normal or reference range as okay. An HDL of 40 mg is not okay. A triglyceride level of 140 mg is also not okay. What is okay? What is desirable? That depends on the parameter being examined. From a basic lipid standpoint, of course, we regard desirable as 60-60-60. Desirability from a lipoprotein standpoint we will cover in a more thorough Track Your Plaque Special Report in future. The wisdom of the masses 1. May 2007 William Davis (0) My sister sent me these quotes:"We don't like their sound, and guitar music is on the way out." Decca Recording Co. rejecting the Beatles, 1962"Stocks have reached what looks like a permanently high plateau." Irving Fisher, Professor of Economics, Yale University, 1929"Airplanes are interesting toys but of no military value." Marechal Ferdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, France"Everything that can be invented has been invented." Charles H. Duell, Commissioner, US Office of Patents, 1899No doubt, conventional wisdom can often be laughably (tragically?) wrong. The problem is that, as absurd as all the above sentiments seem to us now and in retrospect, they represented the view of many people years ago. These views were held by many, including many people in positions of power and decision-making responsibility.A more relevant but nonetheless laughable and widely held belief in 2007: coronary heart disease should be treated with hospital procedures. Why is a disease that requires 30 years to develop treated only at the final moments with a procedure? Do you only change your car's oil when the engine is on its last legs? Or, do periodic, relatively effortless oil changes during the life of the car make better sense?I witness just how brainwashed the public has become with this crazed notion when I meet someone socially at, say a fundraiser or cocktail party. When they ask what I do, I tell them I'm a cardiologist. The invariable response: "Oh, what hospital do you work out of?"I tell them I don't, that I take care of the majority of heart disease right from the office. 99% of the time I get a puzzled look. If we had comic bubbles above our heads revealing our internal thoughts, it would read "Yeah, right. What a kook."The notion that coronary heart disease is something that is manageable with simple tools for the majority of us in the early stages is entirely foreign to almost everybody. The hospitals and the medical industry have so succeeded in dazzling the public with images of staff in scrubs, rushing from emergency to emergency, lights flashing, scalpels flying. . . how can you possibly accomplish this at home or anywhere outside of the high-tech world of the hospital? Well, I'm a cardiologist and I do it every day. We all need a figurative dose of electroshock therapy to shake ourselves of this crazy notion. How important is l-arginine? 30. April 2007 William Davis (13) Perhaps more than any other supplement, l-arginine causes frustration and confusion. It’s difficult to find, sometimes quite expensive, and some preparations cause loose stools.Just how necessary is it?L-arginine, you’ll recall, is a source of nitric oxide, or NO. Though it’s the same stuff as in car exhaust, NO provides a critical signaling role in your body’s cells that regulate a multitude of functions. Among the important roles of NO is to powerfully dilate, or relax, arteries. A constant flow of NO is required for health, particularly since each molecule persists only a few seconds. L-arginine is the body’s source of nitric oxide. In addition, a peculiar but very effective blocker of l-arginine called asymmetric dimethylarginine, or ASDM, has recently been discovered to prevent the production of NO. Varied conditions like hypertension, diabetes, high cholesterol, excessive saturated fat or processed carbohydrate intake all lead to heightened levels of ASDM, often several-fold greater levels, and thereby effectively blocking NO production. The “Arginine Paradox” is the name that some researchers in this field have given to the unusual property of l-arginine supplementation to “overpower” the blocking effects of ASDM. This is somewhat unusual in biologic systems in that an agent that blocks a receptor cannot usually be outmuscled by providing excess material for a reaction. Kind of like hoping that your car runs faster simply by topping up the gas tank. Concrete observable benefits have been made for l-arginine in clinical trials, such as arterial relaxation that results in arterial enlargement (which can actually be seen in the cath lab); anti-inflammatory effects; reduction of blood pressure; enhancement of insulin responses, etc. All of these effects can be connected to beneficial properties that may facilitate atherosclerotic plaque regression and, indeed, there are limited data to document that this is true. Drug companies may be greedy, but they’re not stupid. They’ve been vigorously pursuing this line of research for some years, a research path that led inadvertently to the erectile dysfunction agent, sildenafil (Viagra), and all its subsequent competitors. (Erectile dysfunction is another expression of endothelial dysfunction, since male erections are driven by the ability to dilate penile arteries.) The wonderful properties of NO enhancement continue to occupy research labs around the world. Wow. So what’s the reluctance? In the early years of the Track Your Plaque program (meaning just a short 7-8 years ago), I was thoroughly convinced that l-arginine was a crucial, necessary part of a plaque regression program. Without it, you would rarely succeed. With it, the odds were tipped in your favor. However, something curious has emerged recently. I’ve seen more and more people dropping their heart scan scores. Not just a little bit, but a huge amount. Witness our most recent record holder, Neal, who dropped his score 51% in 15 months. Just five years ago, this magnitude of reversal was unimaginable. Granted, Neal is our record holder, but others are obtaining 10, 18, 24, 30% drops in scores all the time. Many have done it without l-arginine. Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score. My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time. There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden. Track Your Plaque and non-commercialism 29. April 2007 William Davis (6) If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site. We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent. That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products. Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info? Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage. I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation. I'd welcome any feedback either through this Blog or through the contact@cureality.com. The nattokinase scam 28. April 2007 William Davis (179) A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase. The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification. Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts. Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase. Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."Don't you believe it. This is patent nonsense. There are several problems with this rationale:--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right. --Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them. The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase. Blood pressure with exercise 27. April 2007 William Davis (10) Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range. We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high. Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel). Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping. Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary. The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90. Vitamin D2 vs. vitamin D3 26. April 2007 William Davis (21) An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well. Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure. The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably. However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol. Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children. D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness. 25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D. << Older posts Newer posts >> Newer posts12...878889909192939495...123124Older posts Cureality | Real People Seeking Real Cures Toggle navigation Home Blog Home Archive Join Now Log in Unexpected effects of a wheat-free diet 17. September 2009 William Davis (59) Wheat elimination continues to yield explosive and unexpected health benefits. I initially asked patients in the office to eliminate wheat because I wanted to help them reduce blood sugar and pre-diabetic tendencies. A patient would come to the office, for example, with a blood sugar of 118 mg/dl (in the pre-diabetic range) and the other phenomena of pre-diabetes or metabolic syndrome (high blood pressure, high inflammation/c-reactive protein, low HDL, high triglycerides, small LDL), and the characteristic wheat belly. Eliminate wheat and, within three months, they lose 30 lbs, blood sugar drops to normal, blood pressure drops, triglycerides drop by several hundred milligrams, HDL goes up, small LDL plummets, c-reactive protein drops. People also felt better, with flat tummies and more energy. But they also developed benefits I did not anticipate:--Improved rheumatoid arthritis--I have seen this time and time again. Eliminate wheat and the painful thumbs, fingers, and other joints clear up dramatically. Many former rheumatoid sufferers people tell me that one cracker or pretzel will trigger a painful throbbing reminder that lasts a couple of hours. --Improved ulcerative colitis--People incapacitated with pain, cramping, and diarrhea of ulcerative colitis (who are negative for the antibodies for celiac disease) can experience marked improvement. I've seen people be able to stop all their nasty colitis medications just by eliminating wheat. --Reduction or elimination of irritable bowel syndrome--Reduction or elimination of gastroesophageal reflux--Better mood--Eliminating wheat makes you happier and experience more stable moods. Just as wheat is responsible for a subset of schizophrenia and bipolar illness (this is fact), and wheat elimination generates dramatic improvement, when you or I eliminate wheat, we also experience a "smoothing" of mood swings. --Better libido--I'm not sure whether this is a consequence of losing a belly the size of a watermelon or improvement in sex hormones (esp. testosterone) or endothelial responses, but more interest in sex typically develops. --Better complexion--I'm not entirely sure why, but various rashes will often dissipate, bags under the eyes are reduced, itching in funny places stops.It's also peculiar how, after someone eliminates wheat for several months, re-exposure of an errant cracker or sandwich results in cramping and diarrhea in about 30% of people. Obviously, people with celiac disease, who can even die of exposure to wheat, are even worse. What other common food do you know of that makes us sick so often, even occasionally with fatal outcome? Is Lp(a) part of your legacy to your children? 15. September 2009 William Davis (21) If you have lipoprotein(a), Lp(a)--the most aggressive known cause of heart disease that no one has heard of--then you need to tell your children. Lp(a) is a "cleanly" inherited genetic pattern: If either parent has it, there's a 50% chance that you have it. If you have it, then there's a 50% likelihood that each of your children has it. (Note that each child experiences a likelihood of 50%, not 50% of your children. This is because each child is conceived as an independent statistical event. So much for romance!)The atherogenicity (plaque-causing potential) of Lp(a) also tends to get transmitted. In other words, if your Dad had a heart attack at age 50 due to Lp(a) and you share Lp(a), then you likely share a similar magnitude of risk as your Dad. If your Mom had Lp(a), though passed quietly at age 89 without any overt evidence of heart disease, then you are likely to share the relatively benign form of Lp(a). For most of us with Lp(a), however, it is best to assume that it has at least some potential for causing heart disease, being the most aggressive cause known. (That is, until we have the ability in everyday clinical practice to characterize Lp(a) by assessing such factors as the size of the apoprotein(a) molecule, the number of kringle "repeats" on the tail, etc. Until then, we need to rely on the crude, though helpful, observation of family history.) At what age should you inform your children? There's no hard-and-fast rule. However, I generally suggest to patients that they talk about Lp(a) with their children when they reach their 20s or 30s, old enough to begin to understand the implications and begin to think about adopting healthier lifestyles. Is treatment required at, say, age 35? That depends on the pattern of Lp(a)-related heart disease in the family: With exceptionally aggressive forms, it might be reasonable to begin treatment at this relatively early age. Do "Heart Healthy" sterols cause heart disease? 9. September 2009 William Davis (19) The sterol question continues to pop up.Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia? Below, I've reprinted a previous Heart Scan Blog post on sterols. Sterols should be outlawedWhile sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:Higher blood levels of sterols increase cardiovascular events:Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.Sterols can be recovered from diseased aortic valves:Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.Sterols are incorporated into carotid atherosclerotic plaque:Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.Though the data are mixed:Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.No association between plasma levels of plant sterols and atherosclerosis in mice and men.The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:Each Nature Valley Healthy Heart Bar contains 400 mg sterols.HeartWise orange juice contains 1000 mg sterols per 8 oz serving.Promise SuperShots contains 400 mg sterols per container.Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.Kardea olive oil has 500 mg sterols per 14 gram serving.WebMD has a table that they say can help you choose "foods" that are sterol-rich.In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products. Some more info on sterols in a previous Heart Scan Blog post: Are sterols the new trans fat? . Why obese people can't fast 9. September 2009 William Davis (21) Why do obese people claim it is impossible to fast?Most overweight people are terrified at the prospect of facing any period of time without ready access to food. Persuading them to begin a program of intermittent fasting is a hopeless cause. They just refuse. Contrary to popular opinion, this is not just glutonny at work. It is the effect of what I call "the cycle of hunger," the 2-hour up and down cycle of rising sugar and insulin, followed by their inevitable fall. The precipitous fall of sugar and insulin triggers mental fogginess, fatigue, and insatiable hunger. (By the way, this is the same phenomenon underlying the silly notion of "grazing.") According to an LA Times article, fasting may be difficult to impossible for some people: "Ruth Frechman, a registered dietitian in Burbank and spokeswoman for the American Dietetic Assn., says she frequently sees such extreme strategies backfire. 'You're hungry, fatigued, irritable. Fasting is not very comfortable. People try to cut back one day and the next day they're starving and they overeat.'" (Not surprising, coming from the American Diatetic Assn. They, along with such agencies as the American Diabetes Association, are vocal proponents of low-fat, high-carbohydrate, "healthy whole grain" diets--you know, the diets that make us fat and diabetic.)Ms. Frechman is correct: Having someone engage in a period of fasting, no matter how brief, when the diet leading up to the fast is filled with "healthy whole grains" and other carbohydrates will result in painful hunger that eventually overcomes any effort. A period of overeating typically follows the aborted attempt. Fasting cannot work as long as the 2-hour cycle of hunger continues. The first step: Eliminate the 2-hour cycle of hunger by dramatically reducing or eliminating carbohydrates. Our preferred method is to eliminate wheat, cornstarch, and sugars. (Just be aware of wheat withdrawal, the fatigue that develops in the first 5 days after wheat elimination that affects up to 30% of people.)Once wheat, cornstarch, and sugars are eliminated, hunger reverts to that of physiologic need--appetite will be smaller and less intense, since it is driven by your body's needs, not by abnormal stimulation from wheat, cornstarch, and sugar. The fear of not having food dissolves, the 2-hour cycle of mental fogginess, fatigue, and hunger will be gone. Intermittent fasting is a wonderful strategy for reducing weight; gaining control over lipids, lipoproteins, and coronary plaque; regaining appreciation for food; reducing appetite. But it's not even worth trying unless you've already eliminated the unnatural appetite triggers that will booby-trap any fasting effort. Test your own thyroid 7. September 2009 William Davis (15) 134 people responded to the latest Heart Scan Blog poll:When I ask my doctor to test my thyroid, he/she: Accommodates me without question 45 (33%)Questions why, but orders the tests 49 (36%)Refuses because you seem "healthy" 20 (14%)Refuses without explanation 4 (2%)Ridicules your request 16 (11%)That's better than I anticipated: 69% of physicians complied with this small request. After all, you're not asking for major surgery. You're just asking for a very basic test, as basic as a blood count or electrolytes. 36% of respondents said that their doctor asked why, but still complied; this is simply practicing good medicine--If there is a problem, your doctor would like to know about it.However, the remainder--31%--were refused in one way or another. Incredibly, 11% were ridiculed.Although this was not asked in the poll, I believe that it is a safe assumption that you asked with good reason: you're abnormally fatigued, you have been gaining weight for no apparent reason or can't lose weight despite substantial effort, or you feel cold at inappropriate times.Let's say you're tired. Ever since last summer, you've suffered a gradual decline in energy.So you ask your doctor to assess your thyroid. He refuses. "You're just fine! There's nothing wrong with you."You disagree. In fact, you are quite convinced that there is something physically wrong. What do you do?You could:--Drink more coffee--Exercise more in the hopes that it will snap you out of your lethargy--Sleep more--Take stimulants of various sortsOr, you could get your thyroid assessed and settle the issue. But how can you get this done when your doctor won't accommodate you, even though you have perfectly fine health insurance and are simply interested in feeling better and preserving your health?You could test your thyroid yourself. This is why we're making self-testing kits available. Test kits are available here. This is yet another facet of the powerful revolution that is emerging: Self-directed health. Trains, planes, and heart scans 4. September 2009 William Davis (10) A Heart Scan Blog reader posted the following question:It is not clear to me why getting a cardiac scan is the necessary first step, if in fact the next step would be to bring down small LDL particles which is revealed on a NMR lipoprofile or VAP test. Why isn't the NMR or VAP test the first thing?Good question. Think of it this way:Lipoproteins, as measured via VAP (Vertical Auto Profile) or NMR (Nuclear Magnetic Resonance), provide a snapshot of risk from a metabolic viewpoint at that moment. Lipoproteins shift with the tides of age, menopause, weight changes, even what you ate last evening for dinner (especially small LDL). There are also other factors that cause coronary plaque, as well, not revealed through lipoprotein testing, such as vitamin D deficiency, smoking, high blood pressure, phosopholipase A2, lipoprotein(a), inflammatory factors, thyroid dysfunction, omega-3 fatty acid deficiency, etc. A heart scan, providing a coronary calcium score, provides an indirect measure of coronary plaque that is the sum total of lipoprotein and other plaque-causing factors that have accumulated up to the time of your scan--regardless of the cause.It means that two females, each 60 years old, with 70% small LDL, HDL 42 mg/dl, triglycerides 150 mg/dl, and mild hypertension, have identical markers for potential coronary risk, but can have widely different heart scan scores. One might have a score of zero, while the other might have a score of 300. Why would the same panel of causes measured at one moment yield wildly different quantities of plaque? Several reasons:1) The lifestyles, eating habits, and weight of each woman differed during their earlier years, not currently reflected in this moment's lipid or lipoprotein patterns. Perhpaps one experienced several years of extraordinary stress from a failed marriage, or suffered through two years of depression that caused her to smoke and overeat. 2) There are hidden factors that affect coronary plaque growth that we are presently not able to detect, e.g., vitamin D receptor genotype, cholesteryl-ester transfer protein variants, variation in inflammatory factors. If we can't measure it, we won't know whether it might influence coronary plaque risk. With all the changes that occur over a person's life, with the uncertainties of yet-to-be-identified causes for coronary plaque, how can you possible know what your risk for heart disease truly is? Yup--a heart scan. Do it and you will know. D2 and D3 are two different things 3. September 2009 William Davis (15) Helena posted this instructive comment in response to the Heart Scan Blog post, Weight loss and vitamin D. It illustrates the confusion common among physicians and pharmacists on the differences between D2 and D3. (Edited slightly for clarity.)Not many weeks ago a colleague of mine (let’s call him Eric) asked me if I knew the difference between D2 and D3 and I told Eric that D2 comes from irradiated mushrooms and D3 comes from wool. In other words, D3 is the same kind of vitamin as humans get from the sun. Humans just don’t get enough and we can’t produce it on our own, like the sheep can. (D3 is natural for humans, D2 is not.)After telling Eric this, he asked me how he would know what he is taking and I gave him the medical definitions of them both (D2 = Ergocalciferol; D3 = Cholecaliciferol). Since I was aware that he had gotten his Vitamin D by prescription, I told him “I am 99.9% sure that you are taking D2, but I would be thrilled to find out I am wrong.” Eric called his pharmacy right away and got the answer I was expecting: ergocalciferol. On confronting the person Eric was talking to, the answer he got back was that Ergocalciferol is the only Vitamin D they are giving out. A week later, Eric had a new appointment with his doctor and decided to ask him about the D2/D3 issue. The doctor said he knew that there was a difference in them both, but could not say what, not even the basic facts I mentioned above. But the doctor stamped a post-it with what he had sent to the pharmacy just to show Eric. “Vitamin D3; 50,000IU tab” is what the stamp said. Eric, off course, got confused and was starting to believe that the pharmacy had made a mistake by giving him Ergocalciferol (D2) since the doctor had given him D3, or at least that is what was stamped on the little note he had. Today, after getting a refill of his Vitamin D he also got and kept all his paperwork that came along with it. Still believing that stamp the doctor had given Eric earlier, he asked me to double and triple check that my definition of D2 and D3 was correct. I did, just for my own sanity, and I was still right. One of the sheets Eric brought me today was the “Patient Education Monograph” sheet stating the drugs and how to use it and so on. The thing that jumped out the most to me was this: Generic Name: Vitamin D – OralCommon Brand name(s): Drisdol, Maximum D3Identification: PA140 Green Oval CapsuleThis is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: ErgocalciferolMy researching mind went into high concentration mood and I started to dig. And this is what I found: The brand name Drisdol is Ergocalciferol (D2), not D3. The Brand name Maximum D3 seems to be hard to find out there in cyber space as a brand name. But the ones I found that were called Maximum D3 seems to be the real stuff, however none of them required a prescription. When trying to find out through the identification number on the pills (PA140) I now know for sure that Eric is taking Vitamin D2 and not the preferred Vitamin D3. The brand name, Drisdol, had the identification W on one side and D92 on the other, but it is still Ergocalciferol. The only conclusion I can draw from all this is that the medical industry does not know or care about the difference in D2 and D3 – it is all same to them. And as long as the pharmacies only give out D2 it does not matter what the doctor prescribe anyway. I know that people are most likely to be prescribed a D2 pill than to be told to buy over-the-counter D3. But it was almost heart breaking to see the letter D and number 3 right next to the drug Drisdol, as we know is a D2 vitamin. It just didn’t make sense to me that they can be labeled as the same type of medication, when we know it is not! Incredible.Why prescribe plant form D2 when you can get perfectly reliable, safe, effective D3--the human form, at the health food store for about $6? Once again, it's the peculiar false bias of physicians and pharmacists: If it's prescription, it must be good; if it comes from a health food store, it must be bogus. Humans need human vitamin D. Plain and simple.For more on the D2 vs. D3 issue, see the Heart Scan Post, The case against vitamin D2. Weight loss: Different causes, different solutions 1. September 2009 William Davis (8) Heart Scan Blog reader, Kris, related this enlightening story of weight loss (slightly edited for clarity).Kris learned that excess weight is gained through multiple causes. The solutions are therefore multiple, not just one change in diet or two. I started studying about my thyroid issue much earlier and did lose some weight. But ever since I started following Dr. Davis’s blog, it has given me confidence that I was on the right track. I did have my thyroid and iodine figured out from other sources, but Dr. Davis helped me to understand the issues with not only the thyroid but vitamin D3, fructose, fish oil, niacin, wheat etc. I have lost 43lb in last 14 months. It seems to me that there are certain percentages of weight connected with different issues. For example, after I gave up alcohol and sugar, I lost about 14lbs from total weight of 243lbs, weight came down to about 229lb. Then it stopped at 229lb, even though I was in the gym almost 5 to 6 days a week with full workouts. After I changed my thyroid medication to natural thyroid hormones (took synthetic T4 for over 10 years), the weight dropped down further 13lbs or so in matter of few days, shape of the face changed from moon shape/double chin to ordinary long face. Then it kind of stopped at around 213-216 lbs. After giving up wheat, reducing carbs, increasing protein intake (whey protein, chicken etc. no soya, no fructose) the weight came down another 14lbs. Now it is around 200-202lbs and I am over 6.2 tall with heavy set of bones. I feel better than I have ever in my life. More stamina, more clarity/no fog, more confidence and 99% of the time relaxed and being able to see the situation from multiple angles. I use to be able to drink a liter or more jack denial without a problem in one evening but now can’t stand half a can of beer (I miss JD). Drinking alcohol makes me sick. I sleep well and if I wake up in the middle of the night, I have no problem going back to sleep. No more out of breath stair climbing at all. One other thing: I used to be the most attractive meal to the mosquitoes, but not anymore. This year I haven’t been bitten once. I take my dog to the park everyday and I do not use any mosquito repellent, what a relief. I don’t know if it is because of thyroid, iodine, wheat or something else. Skin texture has changed dramatically. I do not use full soap or shampoo, 20% borax, 10 percent of my soap or shampoo for scent and rest water, mixed in a 500ml bottle. No more dandruff, dry skin, pimples for me. Dr. Davis I am thankful to people like you who have the ability to see beyond what you have been taught and have the guts to say the way it is. Most of us work to make living on daily basis but some make their living while spreading their knowledge to save lives. Dr Davis you are one of those few people. Please keep it going. Calling all losers! 29. August 2009 William Davis (14) I'd like to invite anyone who has followed the Track Your Plaque Break the Weight Barrier program to consider posting their stories and photos on the Heart Scan Blog. Because our focus is prevention and reversal of coronary heart disease, we have not made an effort to catalog the weight loss experience that people have while on the program. For many, weight loss has been substantial. (Several people this week alone have reported weight loss of 9 to 46 lbs in the past 6 months.)It would be helpful to hear and see these results. For those of you who don't mind having a story and photo on this Blog, please come back in future to post your results. You will find this post by entering "weight loss" into the site-specific search bar at the top of the page. Weight loss and vitamin D 28. August 2009 William Davis (28) At the start of her program, Penny's 25-hydroxy vitamin D blood level showed the usual deficiency at 22 ng/ml. She supplemented with 8000 units of vitamin D. Another 25-hydroxy vitamin D blood level several months later showed a level of 67.8 ng/ml, right on target. But Penny also began our diet, including the elimination of wheat, cornstarch, and sugars, and, over 6 months, lost 34 lbs. Now a much trimmer 146 lbs (still more to go!), another vitamin D blood level: 111 ng/ml. Penny's weight loss means that the vitamin D is distributed in a smaller total volume, particularly a lower volume of fat. This is a common phenomenon with substantial weight loss: lose weight and the need for vitamin D is reduced. The reduction in dose is roughly proportion to the weight lost. Vitamin D should therefore be reassessed with any substantial change in weight of, say, 10 lbs or more, either up or down, because of the influence of fat on vitamin D blood levels. Some references on this effect:Men and women over age 65:Adiposity in relation to vitamin D status and parathyroid hormone levels: a population-based study in older men and women.Obese women:Low 25-hydroxyvitamin D concentrations in obese women: their clinical significance and relationship with anthropometric and body composition variablesObese children:Hypovitaminosis D in obese children and adolescents: relationship with adiposity, insulin sensitivity, ethnicity, and season.African-Americans:Relationship of vitamin D and parathyroid hormone to obesity and body composition in African Americans.Although the bulk of the effect is most likely due to sequestration by fatty tissue, perhaps less sun exposure in obese people also contributes:Body mass index determines sunbathing habits: implications on vitamin D levels. << Older posts Newer posts >> Newer posts12...363738394041424344...123124Older posts
How old are you? 17. October 2009 William Davis (21) George walks into my office. I ask him his age. "I'm 21 years old," he declares. Yet I look at George. He's got gray thinning hair, his posture is slumped forward rather than erect, the flesh on his upper arms hangs loosely, he's got wrinkles on his hands and face, brown spots on the back of his hands and arms. He looks more like 70 years old to me. "I don't think you're 21 years old. I think you're 70.""Prove it," he says.Okay. What now? Minus any formal identification like a driver's license, how do I prove that George is really 70-something and not 20-something? Not an easy thing, when you think about it. If George were a tree, I'd cut him down and count his rings. Is there such a phenomenon in humans? This is actually a fascinating area of research, looking for reliable biomarkers of aging. Among the most quantitative markers of aging is telomere length. Telomeres were once dismissed as nonsense sequences in DNA. However, more recent thought among geneticists is that telomeres shorten with aging and provide the body's cells a timeline of aging. This way, George's cells act like they are 70, not 13, and don't start producing gobs of growth hormone and testosterone in preparation for puberty. What can slow or stall the shortening of telomere length? There are two I'm aware of:1) Caloric deprivation--i.e., taking in fewer calories. This was among the theories explored by Dr. Roy Walford during his Biosphere2 experience, based on his work in mice that showed that caloric deprivation nearly doubled lifespan. 2) Vitamin D--Richards et al (2007) found that, the higher the vitamin D, the longer the telomere length. The highest vitamin D levels conferred a 5-year effective difference in telomere length. So, if I could look inside George's cells and count his telomeres, I could judge with confidence whether he was 21 or 70. Or, he could take vitamin D sufficient to increase blood levels to a healthy range and be more like 65.
No high blood pressure 14. October 2009 William Davis (20) Primitive cultures that were, until recently, unexposed to the modern world, reveal some important insights into blood pressure. The Yanomamo of South American, the Xingu Indians of Brazil, rural Kenyans, and the natives of Papua, New Guinea have average blood pressures of 103/63 mmHg. Even more incredibly, while 90% of modern Americans will develop high blood pressure as they age, the members of these primitive cultures do not develop age-related hypertension. What's the secret? Perhaps the full "secret" of their remarkably low blood pressure has not been fully unraveled, but several observations have emerged:--They are not exposed to modern processed foods like pretzels, crackers, and breakfast cereals. --Low-carbohydrate foods. Carbohydrates are largely the product of the food industry, convenience foods bought in stores. No such thing in the jungle. --Living outdoors, having to forage and hunt, walk to your destination, not drive or wait in line for food. --Outdoor lives, wearing little more than a few strands of clothing, exposes you to plentiful vitamin D activation from sunlight exposure.--Consuming wild game, rich in omega-3 fatty acids, enhances endothelial health and reduces blood pressure. --Wild plants, roots, and berries, as well as wild game, along the coast, are richer in iodine. The studies examining the habits of the Yanomamo and other primitive cultures focused principally on sodium intake. Indeed, the very low sodium intake of primitive cultures was associated with lower blood pressure--up to 6 mmHg reduction. But there's clearly more to learn than "cut your salt."
Name that food 13. October 2009 William Davis (30) What common food can:• Cause destructive intestinal damage that, if unrecognized, can lead to disability and death? • Increase blood sugar higher and faster than table sugar?• Trigger an autoimmune inflammatory condition in the thyroid (Hashimoto’s thyroiditis)? • Create intestinal bloating, cramps, and alternating diarrhea and constipation, often labeled irritable bowel syndrome? • Trigger schizophrenia in susceptible individuals? • Cause behavioral outbursts in children with autism?• Cause various inflammatory diseases such as rheumatoid arthritis, ulcerative colitis, dermatitis herpetiformis, systemic lupus, pancreatic destruction, and increase measures of inflammation like c-reactive protein?• Cause unexplained anemia, mood swings, fatigue, fibromyalgia, eczema, and osteoporosis?The food is wheat. Yes, the ubiquitous grain we are urged to eat more and more of by the USDA (8-11 servings per day, according to the USDA food pyramid), American Heart Association, American Dietetic Association, and the American Diabetes Association. Wheat is among the most destructive ingredients in the modern diet, worse than sugar, worse than high-fructose corn syrup, worse than any fat. What other common food can result in such an extensive list of diseases, even death?Celiac disease alone, a severe intestinal inflammatory condition from wheat gluten, affects an estimated 3 million Americans (Celiac Disease Foundation). The medical literature is filled with case reports of deaths from this disease, often after many years of struggle with incapacitating intestinal dysfunction and the sufferer's last days plagued by encephalopathy (brain inflammation). What happens when you remove wheat from the diet? The majority of people quickly shed 20-30 lbs in the first few weeks, selectively lost from the abdomen (what I call “wheat belly”); blood sugar plummets; triglycerides drop up to several hundred milligrams, HDL increases, LDL drops (yes, wheat elimination is a means of achieving marked reduction in LDL cholesterol, especially the small, heart disease-causing variety); c-reactive protein plummets. In addition to this, intestinal complaints improve or disappear, rashes improve, inflammatory conditions like rheumatoid arthritis improve, diabetes can improve or be cured, and behavioral disorders and mood improve.Along with the ill-fated low-fat dietary advice of the last 40 years, the advice to eat plenty of "healthy whole grains" is responsible for untold disease and suffering. Yes, if you start with a fast food and junk diet and replace some of the calories with whole grains, you will be better off. (That was the logic--the Nutritional Syllogism--of the studies that established the benefits of whole grains over processed, "white" grains.) But eliminate wheat grains and health takes a huge leap forward. And, no, there is no such thing as wheat deficiency--B vitamins, insoluble fiber, some protein--can easily be replaced by other foods.
Heart Defects Simplified 12. October 2009 William Davis (0) For as long as I've known him, echocardiography technologist, Ken Heiden, has had a deep fascination with congenital heart disease. Ken has just written a wonderful book on congenital heart disease called Heart Defects Simplified. While this is a bit off-topic for the Heart Scan Blog, I know that there is a serious lack of helpful information for people with congenital heart disease and parents of children with congenital heart defects. So I asked Ken to tell us something about his book. WD: I've reviewed your book and have been thoroughly impressed with the clarity and detail with which you handle a complicated topic. You somehow manage to make it easy to grasp, far more than any other resource I've used in past. Do you feel that your book serves a previously unmet need? KH: This book serves an unmet need in that it presents the complex subject of congenital heart defects in a simplified manner. Most books on this subject are anywhere from 300-1700 pages in length and tend to be written for doctors. Further, most of these books have very few diagrams, and they rely upon their explanations to describe these defects. Heart Defects Simplified is 104 pages in length, describes the most common defects, including surgical repairs, in a two-page format with full-color diagrams on the left and complete descriptions on the right of each chapter. The book is particularly written for sonographers, nurses and parents, but it is valuable for anyone interested in this subject. It is particularly useful in clinical situations because it is convenient to lay out at your side with a coil-bound format and durable pages. Further, there are appendixes which include "Surgical Procedures in Alphabetical Order," "Prevalence of Congenital Heart Disease," "Scanning Protocols for Echocardiographers," "Imaging Tips," a glossary and a worksheet for echocardiographers. WD: I know that many people with loved ones who have congenital heart defects, particularly parents of children with such conditions, are often kept in the dark about the details of the condition. Is your book suitable for the non-technical reader, such as parents? KH: This book is an excellent resource for parents. It is written in language that is understandable by parents as well as technologists and nurses. The full-color diagrams provide invaluable insight into this very complex world. Most importantly, this book attempts to make the subject of congenital heart defects accessible to anyone who wishes to comprehend this subject. WD: I understand that people with congenital heart defects and parents are active participants in online discussion groups. Will your book serve as a resource for people who participate in these groups? KH: This book is not only a resource for sonographers and parents, but the book is accompanied by a blog (HeartDefectsforEveryone.blogspot.com) that attempts to address many of the concerns commonly encountered with congenital heart defects. This blog is a work in progress, but I hope to provide a forum for parents, healthcare personnel, and others to share their questions and concerns about congenital heart disease.
My experience with the omega-3 index 8. October 2009 William Davis (23) I just got back my own results from the Gene Smart laboratory reporting my omega-3 index and omega-6:omega-3 ratio. My results:Omega-3 index: 8.2%Omega-6:omega-3 index: 3.2 to 1Not too bad, but not as good as I'd expected. Hmmm. Although the omega-3 index of 8.2% puts me in the lower risk category for sudden cardiac death, I was hoping for a level of 10% or slightly greater, the level that I believe is more likely to be related to plaque inactivation or reversal. I obtained this level of omega-3 averaging an intake of EPA and DHA of about 2500 mg per day. I was somewhat disappointed by the omega-6:omega-3 index. Although it's clearly better than the American average range of 20:1, it is short of the ideal of 2:1 or even 1:1. Since I purposely avoid omega-6-rich sources like corn oil, vegetable oils, sunflower or safflower oils, I wonder if I've overdone the nuts. The two ways to improve the omega-6:omega-3 ratio are to 1) decrease omega-6, or 2) increase omega-3. I'm going to do both. So I thought I was doing pretty well. But there's clearly room for improvement.Remember: If just reduction of cardiovascular risk is your interest, then a lackadaisical attitude towards these issues might work. But if your interest is elimination of risk and reversal of atherosclerotic plaque, then it pays to go the extra mile. In this case, knowing your omega-3 index and omega-6:omega-3 ratio might tighten up your program.
The Omega-3 Index: The higher, the better? 6. October 2009 William Davis (26) So you take a few fish oil capsules every day and eat fish once or twice a week. What is the blood and tissue level of omega-3 fatty acids generated by your habits? A number of variables enter into the equation. For instance, if you take fish oil capsules, what is the concentration of omega-3 fatty acids? How well are they absorbed? After absorption, how effectively are omega-3 fatty acids incorporated into cell membranes?Even if you take fish oil supplements, it is hard to know just how much you’ve increased blood levels. It is now possible to measure the amount of omega-3 fatty acids in your bloodstream, a value called the omega-3 index. Too little and you might still be at high risk for cardiovascular events. The Omega-3 index and sudden cardiac deathTwo large studies have demonstrated that higher omega-3 blood (the level in red blood cells, or RBCs) levels were associated with reduced likelihood of sudden cardiac death. The risk for sudden cardiac death was 10-fold higher for the lowest omega-3 RBC levels compared to the highest.Harris WS 2008; adapted from Siscovick DS et al 1995 and Albert CM et al 2002(The omega-3 Index was derived from whole blood omega-3 levels, which correlate with RBC omega-3 levels, and are thus “estimated.”)What’s the average omega-3 RBC level for Americans? Most Americans have omega-3 RBC levels in the 2.5-4.0% range, consistent with the tallest bars at the left and associated with greatest risk for sudden cardiac death. People with heart disease can have levels less than 1%. Some authorities propose that this new measure be called the omega-3 index. Subsequent studies have shown that the omega-3 index has greater power to discriminate who will have a heart attack or die from sudden cardiac death better than any other common laboratory measure of coronary risk, including LDL cholesterol, HDL cholesterol, triglycerides, total cholesterol to HDL ratio, homocysteine, and c-reactive protein.Just as hemoglobin A1c offers a 3-month look into blood glucose levels, the omega-3 index reflects your long-term omega-3 intake. The quantity of RBC omega-3s also closely parallels the quantity of omega-3s in heart tissues.What is an ideal omega-3 index?The above studies relating RBC omega-3 levels and sudden cardiac death suggest that a level of 6.3-7.3% is associated with far fewer fatal events?but events are not eliminated at this level. Is there even greater benefit with levels higher than 6.3-7.3%?A recent analysis of females from the Harvard School of Public Health suggested that RBC omega-3 levels as high as 8.99% were still associated with non-fatal heart attack (myocardial infarction), compared to 9.36% in those without heart attacks. This suggests that even higher levels are necessary to prevent non-fatal events. Should we target 10%? 12%? Maybe higher? Any higher and we are toeing the level achieved by the Inuits, the “Eskimoes” of Greenland, northern Canada and Alaska who have been observed to have a low rate of heart disease.What’s your omega-3 index?The appreciation of the importance of omega-3 fatty acids marks one of the greatest health revelations of the last 50 years. We can now measure it.The ability to measure the proportion of omega-3 fatty acids in red blood cells may provide yet another means for all of us to further reduce risk for cardiovascular events.If you are interested in knowing your omega-3 index, we are now making the fingerstick test kits available by going here.
Vitamin D increased my cholesterol 2. October 2009 William Davis (38) A friend told me this story. Her friend, Linda, had added vitamin D to her daily supplements. Because she'd had a vitamin D blood level of 22 ng/ml, she was taking 6000 units per day. However, Linda also had a high cholesterol value with a total cholesterol of 231 mg/dl. After several months on the vitamin D, she had another cholesterol panel. Total cholesterol: 256 mg/dl. "It must have been the vitamin D! So I stopped it right away." Is this true? Does vitamin D raise the level of blood cholesterol? Yes, it does. But it's a good thing. Let me explain. Followers of The Heart Scan Blog know that total cholesterol is really a mix of 3 other factors:Total cholesterol = LDL cholesterol + HDL cholesterol + triglycerides/5This is the Friedewald equation, still used today in over 95% of cholesterol panels. So, by the Friedewald equation, anything that increases LDL, HDL, or triglycerides will increase total cholesterol. One of the spectacular changes that develops over a year of taking vitamin D is that HDL cholesterol skyrockets. While sensitivity to this effect varies (probably on a genetic basis), HDL increases of 10, 20, even 30 mg/dl are common. A starting HDL, for instance, of 45 mg/dl can jump up to 65 or 70 mg/dl, though the effect requires up to a year, sometimes longer. Vitamin D can also reduce triglycerides, though the effect is relatively small, usually no more than 20 mg/dl or so. Likewise, the effect on LDL is minor, with a modest reduction in the small type of LDL. So the dominant effect of vitamin D from a cholesterol standpoint is a substantial increase in HDL. Looking at the equation, you can see that an increase in HDL is accompanied by a commensurate increase in total cholesterol. If HDL goes up 25 mg/dl, total cholesterol goes up 25 mg/dl. So Linda is absolutely correct: Vitamin D increases cholesterol--but it's a good thing that reduces risk for heart disease and is an important part of a coronary plaque-reversal program. This is yet another reason why I advocate elimination of total cholesterol on lipid panels. There is no useful information in the total cholersterol value, only the potential for misinformation.
Nutrtional ignorance is not unique to the U.S. 28. September 2009 William Davis (20) Heart Scan Blog reader from Australia, Michaela, also a mother of a son with a complex congenital heart defect, wrote this series of e-mails to me. (Published with Michaela's permission.) I've been reading the article, Valve disease and Vitamin D from April '07, by Dr William Davis. I'm hoping you may have some information on the topic. I'm hoping someone will have time to help me. I have been supplementing my 15 year old son with Vit D for 4 months but only 1000 (U) per day. I would like to increase the dosage but am not sure if I would do him more harm than good. I have been researching vitamins and supplements on the net for a few months and have been amazed at what I have found. I only wish I had done it years ago. My son has been let down by the Australian Medical Profession and it's a race against time now to keep him well and avoid a heart transplant. My son was born with aortic stenosis and had a valvotomy at 4 weeks of age. This damaged the aortic valve and he had a Ross Repair procedure at aged 3. This left him with a damaged heart muscle and leaking aortic & pulmonary valves. In May '08, his heart grew more enlarged, causing the mitral & tricuspid valves to also leak. I took him to Bangkok in Feb this year where he had 70 million of his own Adult Stem Cells directly injected into his heart muscle with the hope of strengthening the muscle and eventually valve replacement. My son has recovered from the surgery and is once again symptom-free, thanks to the wonderful advice followed by the Author & Cardiologist, Stephen T. Sinatra. I have followed his supplement regime and what a difference! Of course, this won't last while my son's valves continue to leak. My son has also developed secondary hyperparathyroidism, bone thinning and hypothyrodism. Vit D & Calcium have something to do with this I believe. My Australian Doctors have never made mention of any vitamins or supplements .... EVER! Transplant is all they will consider and we are not having it. If you have any info or links to any sites which may be useful to me, could you email them to me? I would be grateful for any help I could get. SincerelyMichaelaI responded to Michaela's e-mail:Hi, Michaela-- Vitamin D is extremely important. Sometimes, hyperparathyroidism and calcium derangements are caused by vitamin D deficiency. You might be able to get help with this from an endocrinologist, since they are the ones who deal with hyperparathyroidism. An endocrinologist might even be familiar with several recent studies that document this phenomenon:Vitamin D therapy in patients with primary hyperparathyroidism and hypovitaminosis DVitamin D deficiency and primary hyperparathyroidismAlso, see the discussions at www.vitamindcouncil.org from Dr. John Cannell.Because of the complexity of your son's health, it might be hazardous to stray too far away from conventional care though you and I know that there are limitations to that perspective. For that reason, I would urge you to press for answers from a knowledgeable endocrinologist. I hope you find the answers you need. William Davis, MDSeveral months later, Michaela provided this update:Hi Dr Davis, I wrote to you back in July regarding my 15 year old son's need for a Heart Transplant through a failed Ross Repair and the possible Vitamin D connection. You sent me some valuable links and I thank you again for that. I just wanted to let you know, I think you have given me the answers. I increased Lee's Vitamin D supplement to 6000U a day and, along with the recommended nutritional supplements of US Cardiologist Dr Stephen T Sinatra, there have been remarkable improvements! Lee also had 70 million of his own Adult Stem Cells injected into his heart in February. As we know, Stem Cell Therapy takes time and Lee was looking like time was quickly running out. I have removed him from the transplant list. He is now reading normal Kidney function, the BNP (Brain Natriuretic Peptide, a measure of heart failure] has dropped by 7000 and his liver size has reduced to where it no longer causes him discomfort. The liver tests show it's still affected but it's function is improving each month. His last Echo was in early July and there had been a reduction in the size of his heart, which is so important. To the Doc's, Lee can't get better, there is only transplant or death so you can imagine the surprise on their faces to see him looking and feeling so well with their tests to back it up. Still, even though it's staring them in the face, they don't want to know about it. They have no interest in what supplements he is on or Stem Cell therapy. God help their other patients. I view them in the waiting room and think of them as lambs to the slaughter. We are not spoiled for choice with Doc's here in Western Australia. I have to take what I can get and there is not many who would take on Lee's case. He was number 1 on the transplant list and a most urgent case. Not many were willing to even look at him with his cardiac history and all I had to help was the arrogant Doc's at the Advanced Heart Failure Unit. They were not at all interested in his secondary hyperparathyroidism. I suppose it didn't matter what else he had compared to his heart problems. Anyway, I'm writing to thank you. Lee would be transplanted or dead now if it wasn't for Dr's like you sharing their knowledge online. I wish I had researched things years ago, Lee might not have sunk so low if I had. I don't know if the transplant can be held off indefinitely, but like I tell Lee, "Stay well. There are amazing people out there doing amazing things, if you can just hang on. The miracle is around the corner." He's so well, you'd have to see him to believe it. But I have 7 kids and Lee is as physically active and as well as the other 6! For how long he can stay like this, I don't know but if his ejection fraction [a measure of left ventricular strength] can keep climbing and his body gets stronger, I have hope for another attempt at valve replacement. I'm still shocked and angry that nutritional supplements have never been mentioned in the 15 years I've been dealing with cardiologists. Surely they know about them. I have read through dozens of reports online of the benefits of them--Why haven't they?! Thank God for the online Doc's such as yourself, the valuable info would never make it out of a Doctor's office in Western Australia! I've had to leave my country for Stem Cell therapy and then implore overseas Doc's for advice and information. What does that say for the Australian Medical Profession? Not a lot! They put him in the position he is in yet don't want to help get him out. I'm so very grateful to you, thank you and God bless. Michaela Note: The above is not meant to be an implicit endorsement of stem cell therapy. This was just part of Michaela's story about her son.
Eat cranberries 24. September 2009 William Davis (17) Most people already know that cranberries are useful for preventing urinary tract infections. Cranberries can also be useful for preventing other sorts of infections, such as dental cavities and stomach ulcers because of cranberry's ability to block bacterial adhesion. Cranberries can also be a useful component of a heart healthy program. Several unique properties of cranberries contribute to various aspects of heart health:• Cranberries are a rich source of pectin--Pectin is a soluble fiber, the sort that binds bile acids in the intestinal tract and naturally reduces LDL cholesterol.• Cranberries are a rich source of polyphenols and flavonoids--Including the wonderfully fascinating anthocyanins, the flavonoids that confer the beautiful red color. Surprisingly, cranberries are richer in polyphenols and flavonoids than blueberries, strawberries, and grapes. Cranberry juice is also rich in these compounds. However, beware of cranberry juice "cocktail," which is diluted with other liquids such as high-fructose corn syrup. Like grapes, cranberries are a source of resveratrol, the polyphenol also found in red wines that some believe is responsible for reduced risk for heart disease and extending life. • Cranberries have high antioxidant activity--Cranberries are among the highest in antioxidant capacity against superoxide radicals, hydrogen peroxide, and hydroxyl radicals, oxidizing factors believed to underlie heart disease, cancer, and aging. Cranberries also reduce the oxidation of LDL cholesterol particles. • Cranberries block uric acid production--Cranberries have the unique ability to block the activity of an enzyme, xanthine oxidase, that converts xanthine to uric acid. Uric acid is believed to add to heart disease risk and is the factor responsible for gout. • Cranberries increase HDL cholesterol--Cranberry juice increases HDL by 3-4 mg/dl. Cranberries are only modest sources of sugars, with 7.19 grams “net” carbohydrates (total carbohydrates minus fiber content) per cup of whole raw cranberries. The best way to eat cranberries is to consume the real thing: eat the whole berry, as in sugar-free cranberry sauce or added to baked dishes like chicken. Second best are dried cranberries. However, be careful of the overly-sweetened dried cranberries that contain added sugar (for a total of 78 grams sugar per cup--far too much). Unsweetened dried cranberries can be purchased, or you can dry them yourself.Cranberry juice is another way to obtain the health benefits of cranberries; the unsweetened juice, while quite tart, is the best with 30.5 grams sugar per 8 oz--so don't drink more than 4 oz at a time. The more common cranberry juice “cocktails” are generally too sugary and/or too dilute for full health benefit. The cranberry harvest season in Wisconsin, Michigan, Oregon, Massachusetts, and New Jersey is just getting underway, so we should be seeing fresh cranberries on store shelves or farmers' markets any day now.
Procedures 'R Us 23. September 2009 William Davis (20) Kay came to the office for an opinion. Over the past 8 months, she'd received a stent to the left anterior descending coronary artery and, during a separate procedure, a stent to the left subclavian artery. "My cardiologist was very capable doing procedures. But when I asked, 'What do I do now?' he barely said a word and handed me a presciption for Crestor." This kind of incredible neglect is the norm: Write a prescription for statin drug, delegate dietary advice to the hospital dietitian who advocates a heart disease-causing low-fat diet, followed by hospital discharge. You are expected to report any recurrent symptoms (which are inevitable), at which point you might "qualify" for another procedure. It would be malpractice if it were not the prevailing standard in the community. Yes, the prevailing standard is neglect--neglect to identify, quantify, and correct all the identifiable causes of heart disease; neglect to discuss the nutritional methods that actually correct the abnormal patterns that cause heart disease; neglect to discuss nutritional supplements or medications beyond statins that further reduce heart disease risk and "need" for more procedures. In other words, the prevailing community standard is to stent, bypass, prescribe statin. It is not to understand why the disease occurred in the first place, correct the causes and minimize or eliminate any future danger or need for procedures. I see consultation after consultation involving stories just like Kay's. People are frightened and they sense intuitively that nobody raised the question of why they have a potentially fatal disease. Don't allow yourself to fall victim to this incredibly neglectful mode of practice, the one that has enriched hospitals, the drug industry, many cardiologists, but does little to address the actual disease.
An exercise in optimism 5. May 2007 William Davis (0) Followers of the Track Your Plaque program already know that maintaining an optimistic viewpoint is important in gaining control over coronary plaque. In fact, I believe that, in many cases, a sense of optimism may make or break your CT heart scan score-reducing efforts. Pessimists rarely drop their score, while optimists do so all the time. This week posed a challenge to my optimism. I spent the last week on jury duty hearing the details of a murder case. For four days, I listened to blow-by-blow testimony about the totally pointless, unprovoked death of a young man by a drug-dealing thug. Much of the witness testimony was from people who shared the hopeless, violent world of the defendant. I was, however, completely impressed by the dedication of the prosecuting attorney, a 50-some year old man who was clearly deeply dedicated to his mission and didn't once provide any indication that he was grandstanding or looking for some personal glory. He was doing his job and trying to obtain justice for the fallen victim. I was equally impressed by the judge, who seemed unfazed by the events but carefully explained why the system worked the way it did. After the trial, he provided some further insights to us jury members and I saw him as a human being who, like the prosecutor, was trying to make a small contribution to making the world better. Though many of the witnesses who testified against the defendant shared his world, I was impressed with their courage in coming forward. They face the threat of reprisals, I'm sure, for coming forward to the law and testifying against a known career criminal. Several of them said that they were not after any reward, but simply wished to do the right thing and provide testimony that proved damning against the defendant. I acted as the jury foreman and I was proud of how the jury members listened carefully, asked intelligent and probing questions, and then helped us render a confident and expeditious sentence: guilty. If anything, despite the tragic circumstances, I was much heartened at how all the participants in this process played their part and justice (at least in the legal sense) was served. Let optimism prevail, even in dire circumstances.
No need to re-invent the wheel 2. May 2007 William Davis (0) I seem to be repeating myself lately, but I think this does bear repeating:There's no need to re-invent the wheel when it comes to gaining control over your heart scan score.The Track Your Plaque program is the most powerful approach known to help you gain control over your coronary atherosclerotic plaque and CT heart scan score, bar none. While 100% of people do not drop their score, more and more people every week are doing so. (One of the admitted weaknesses of the Track Your Plaque website is our failure to list more success stories; we're working on it.)The basic program is quite simple:--The Rule of 60 for lipids (LDL 60 mg/dl; HDL 60 mg/dl or greater; triglycerides 60 mg/dl or less)--Identify hidden causes of plaque, esp. small LDL, Lp(a), and IDL, followed by specific corrective action--Fish oil--minimum 1200 mg per day of EPA + DHA--Normal vitamin D3 blood levels (We aim for 25-OH-vitamin D3 of 50-60 ng/ml)--Normal blood sugar (<100 mg/dl)--Normal blood pressure (<130/80)--An optimistic attitude Much of the other stuff--vitamin K, matrix metalloproteinase reducing strategies, flavonoid strategies, exercise-induced hypertension, etc.--are, for the majority, fluff. Their real role is in people who may have failed in stopping the rise of their heart scan score just doing the basics of the program. If you neglect the basics, hoping to find some magic potion, I'm afraid the overwhelming likelihood is that you will fail. I've seen it happen time and again. Someone will come to my office with an extraordinary list of supplements--hawthorne, dozens of anti-oxidants, EDTA, concentrated flavonoid preparations, and on and on. Not only is it shockingly expensive to do this, it's also unnecessary and foolhardy. This kind of unfocused, hocus-pocus in the hopes of getting it right fail time after time. The Track Your Plaque program, while not foolproof, is the best I know of. Stick to the basics and wander off when the basics fail. But there's extraordinary power in just achieving the basics.
Are we a front for drug companies? 2. May 2007 William Davis (3) I was shocked recently when someone accused me and the Track Your Plaque website of being nothing more than a front for the drug industry, that we are promoting concepts with the hidden pharmacuetical agenda behind us. Don't make me laugh. How in the world that kind of impression could be gotten from either the Heart Scan Blog or the Track Your Plaque website is beyond me. But I occasionally do need to state explicity: We do not promote drugs, neither this Blog nor the Track Your Plaque website has ever sought nor been backed by pharmaceutical money. The only money that supports this website is our own and that from paying Track Your Plaque members. In fact, I am quite proud of the unbiased content and commentary on both venues. I challenge anyone to point out how and where there is any suggested relationship to a hidden source of commercial backing. I assure you, there is none. If I say a drug is worth you and your doctor considering, then I say so with a true belief in it, not because somebody or some company paid me to say so. If I say a drug stinks, I believe that too. If we use a specific supplement in the program, it's because we believe it truly adds value to a plaque-reversal program. We receive no money from drug, supplement, or other commercial interests to promote their products. Period.
What is "normal"? 1. May 2007 William Davis (2) When it comes to laboratory values and medical testing, a common dilemma is knowing what is "normal." Let me explain. First of all, when you receive a laboratory result for a test, a "reference range" or "normal range" is usually provided. Where did that range come from? It varies from test to test. For instance, a low potassium is easy, because low potassium levels can lead to life threatening consequences, e.g., dangerous heart rhythms. High potassium likewise, because dangerous phenomena develop when potassium generally exceeds 5.5 mg/dl or so.But what about something like HDL or LDL. Here's where confusion reigns. Often, "normal" is obtained by taking the average and saying that any value plus or minus two standard deviations (remember that painful class?) represents normal or reference range. If that were true, what if we applied that principle to body weight. If we weighed several thousand adult women, the average would be in the neighborhood of 172 lbs (no kidding). Does that mean that 172 lbs plus or minus two standard deviations is normal? No, of course not. There is therefore a distinction between "normal" and "desirable". For HDL cholesterol, your laboratory report might say that an HDL cholesterol of 40-60 mg/dl is normal. But is it desirable? I don't think so. The most frequent HDL level for a male with a heart attack is 42 mg/dl--hardly desirable. Let's take triglycerides. The average triglyceride level in the U.S. is somewhere around 140 mg/dl. For those of us who do a lot of lipoprotein testing, we can tell you that triglycerides at this level, though generally regarded as being within the normal range, are associated with flagrant and obvious excesses of several abnormal lipoprotein particles that contribute to coronary plaque growth (VLDL and often IDL; small LDL; drop in HDL and shift towards small HDL).So, always take the so-called "normal" or "reference" values on a lab report as crude guidelines that often have little or nothing to do with health or desirability. Unfortunately, many physicians are not aware of this and will declare any value within the normal or reference range as okay. An HDL of 40 mg is not okay. A triglyceride level of 140 mg is also not okay. What is okay? What is desirable? That depends on the parameter being examined. From a basic lipid standpoint, of course, we regard desirable as 60-60-60. Desirability from a lipoprotein standpoint we will cover in a more thorough Track Your Plaque Special Report in future.
The wisdom of the masses 1. May 2007 William Davis (0) My sister sent me these quotes:"We don't like their sound, and guitar music is on the way out." Decca Recording Co. rejecting the Beatles, 1962"Stocks have reached what looks like a permanently high plateau." Irving Fisher, Professor of Economics, Yale University, 1929"Airplanes are interesting toys but of no military value." Marechal Ferdinand Foch, Professor of Strategy, Ecole Superieure de Guerre, France"Everything that can be invented has been invented." Charles H. Duell, Commissioner, US Office of Patents, 1899No doubt, conventional wisdom can often be laughably (tragically?) wrong. The problem is that, as absurd as all the above sentiments seem to us now and in retrospect, they represented the view of many people years ago. These views were held by many, including many people in positions of power and decision-making responsibility.A more relevant but nonetheless laughable and widely held belief in 2007: coronary heart disease should be treated with hospital procedures. Why is a disease that requires 30 years to develop treated only at the final moments with a procedure? Do you only change your car's oil when the engine is on its last legs? Or, do periodic, relatively effortless oil changes during the life of the car make better sense?I witness just how brainwashed the public has become with this crazed notion when I meet someone socially at, say a fundraiser or cocktail party. When they ask what I do, I tell them I'm a cardiologist. The invariable response: "Oh, what hospital do you work out of?"I tell them I don't, that I take care of the majority of heart disease right from the office. 99% of the time I get a puzzled look. If we had comic bubbles above our heads revealing our internal thoughts, it would read "Yeah, right. What a kook."The notion that coronary heart disease is something that is manageable with simple tools for the majority of us in the early stages is entirely foreign to almost everybody. The hospitals and the medical industry have so succeeded in dazzling the public with images of staff in scrubs, rushing from emergency to emergency, lights flashing, scalpels flying. . . how can you possibly accomplish this at home or anywhere outside of the high-tech world of the hospital? Well, I'm a cardiologist and I do it every day. We all need a figurative dose of electroshock therapy to shake ourselves of this crazy notion.
How important is l-arginine? 30. April 2007 William Davis (13) Perhaps more than any other supplement, l-arginine causes frustration and confusion. It’s difficult to find, sometimes quite expensive, and some preparations cause loose stools.Just how necessary is it?L-arginine, you’ll recall, is a source of nitric oxide, or NO. Though it’s the same stuff as in car exhaust, NO provides a critical signaling role in your body’s cells that regulate a multitude of functions. Among the important roles of NO is to powerfully dilate, or relax, arteries. A constant flow of NO is required for health, particularly since each molecule persists only a few seconds. L-arginine is the body’s source of nitric oxide. In addition, a peculiar but very effective blocker of l-arginine called asymmetric dimethylarginine, or ASDM, has recently been discovered to prevent the production of NO. Varied conditions like hypertension, diabetes, high cholesterol, excessive saturated fat or processed carbohydrate intake all lead to heightened levels of ASDM, often several-fold greater levels, and thereby effectively blocking NO production. The “Arginine Paradox” is the name that some researchers in this field have given to the unusual property of l-arginine supplementation to “overpower” the blocking effects of ASDM. This is somewhat unusual in biologic systems in that an agent that blocks a receptor cannot usually be outmuscled by providing excess material for a reaction. Kind of like hoping that your car runs faster simply by topping up the gas tank. Concrete observable benefits have been made for l-arginine in clinical trials, such as arterial relaxation that results in arterial enlargement (which can actually be seen in the cath lab); anti-inflammatory effects; reduction of blood pressure; enhancement of insulin responses, etc. All of these effects can be connected to beneficial properties that may facilitate atherosclerotic plaque regression and, indeed, there are limited data to document that this is true. Drug companies may be greedy, but they’re not stupid. They’ve been vigorously pursuing this line of research for some years, a research path that led inadvertently to the erectile dysfunction agent, sildenafil (Viagra), and all its subsequent competitors. (Erectile dysfunction is another expression of endothelial dysfunction, since male erections are driven by the ability to dilate penile arteries.) The wonderful properties of NO enhancement continue to occupy research labs around the world. Wow. So what’s the reluctance? In the early years of the Track Your Plaque program (meaning just a short 7-8 years ago), I was thoroughly convinced that l-arginine was a crucial, necessary part of a plaque regression program. Without it, you would rarely succeed. With it, the odds were tipped in your favor. However, something curious has emerged recently. I’ve seen more and more people dropping their heart scan scores. Not just a little bit, but a huge amount. Witness our most recent record holder, Neal, who dropped his score 51% in 15 months. Just five years ago, this magnitude of reversal was unimaginable. Granted, Neal is our record holder, but others are obtaining 10, 18, 24, 30% drops in scores all the time. Many have done it without l-arginine. Now, how about the people who have failed to stop a rising score? Would they do better with l-arginine as part of the mix? I believe so, but sometimes we never quite know except in retrospect. It has been a great dilemma for us trying to predict from the starting gate who will or who won’t drop their heart scan score. My view from the trenches is that l-arginine packs its greatest atherosclerosis-fighting punch in the first year or two of use, when “endothelial dysfunction” is likely to be present (abnormal artery constriction). But as all other strategies take hold—fish oil, correction of lipid and lipoprotein abnormalities, weight loss (big effect), vitamin D (another very big effect), etc.—endothelial behavior improves over time. Perhaps l-arginine becomes a less necessary component over time. There’s no doubt that uncertainty still surrounds the use and science surrounding l-arginine. However, if you’re interested in stacking the odds in your favor, particularly during the first year or two of your plaque-reducing efforts, I think that l-arginine is worth considering. It is cumbersome, it can be expensive, some preparations may even be foul. But in the big picture of life, with hospitals trying every possible ploy to get your body on a table for a procedure, doctors perverting their mission by signing employment contracts with hospitals and agreeing to usher you into the hospital as a paying patient whenever possible, and drug companies viewing you and me as a market for medications which may or may not be helpful, l-arginine is surely not that big a burden.
Track Your Plaque and non-commercialism 29. April 2007 William Davis (6) If you're a Track Your Plaque Member or viewer, you may know that we have resisted outside commercial involvement. We do not run advertising on the site, we do not allow drug companies to post ads, we do not covertly sponsor supplements. We do this to main the unbiased content of the site. We've seen too many sites be tempted by the money offered by a drug company only to see content gradually drift towards providing nothing more than cleverly concealed drug advertising. I personally find this deceptive and disgusting. Ads are ads and everyone knows it. But when you subvert content, secretly driven by a commercial agenda, that I find abhorrent. That said, however, I do wonder if we need the participation of some outside commercial interests to help our members. In other words, many (over half) of the questions and conversations we have with people is about what supplement to take, or what medication to take. While we cannot offer direct medical advice online (nor should we) because of legal and ethical restrictions, I wonder if could facilitate access to products. Many people struggle, for instance, with trusted sources for l-arginine, vitamin D, fish oil. Other people struggle with finding a heart scan center because of the changing landscape of the CT scanning industry. Could we somehow provide a clear-cut segment of the website that clearly demarcates what is commercial and non-Track Your Plaque-originated, yet at least provides a starting place for more info? Ideally, we would have personally tried and investigated everything there is out there applicable to the program. But that's simply impossible at this stage. I feel strongly that we will never run conventional ads on the site. Nor will we ever permit any outside commercial interest to dictate what and how we say something. The internet world is full of places like that. Look at WebMD. I find the site embarassing in the degree of commercial bias there. We will NEVER sell out like that, regardless of the temptation. People with heart disease are all conducting a war with the commercial forces working to profit from them--hospitals, cardiologists, drug companies, medical device companies (yes, even they advertise to the public, e.g., implantable defibrillators--no kidding). Genuine, honest, unbiased information is sorely needed and not from some kook who either knows nothing about real people with real disease, or has a hidden agenda like selling you chelation. I'd welcome any feedback either through this Blog or through the contact@cureality.com.
The nattokinase scam 28. April 2007 William Davis (179) A conversation about vitamin K2 commonly leads to confusion. Several people have asked about something called nattokinase. The scientific data on the potential role of vitamin K2 deficiency in causing both osteoporosis and vascular calcification is fascinating. Along with vitamin D3, vitamin K2 may be an important factor in regulation of calcium metabolism. Supplementation may prove to be a major strategy for inhibition of vascular calcification. Obtaining K2 in the diet is tricky, since it's present in just a handful of foods: egg yolks, liver, traditional cheeses, and natto. This is where the confusion starts. Natto is a Japanese fermented soy product. I've had it and it's quite disgusting. Nonetheless, Japanese who eat natto experience less fracture. (A parallel study in heart disease has not been performed.) Natto is also a source of another substance called nattokinase. Advocates (otherwise often known as supplement distributors) claim that nattokinase is a "fibrinolytic", or blood clot-dissolving, preparation that "improves blood flow, protects from blood clots, and prevents heart attacks and strokes."Don't you believe it. This is patent nonsense. There are several problems with this rationale:--Any oral fibrinolytic agent is promptly degraded in the highly acid environment of the stomach. That's why all medically used fibrinolytics are given intravenously. Drug companies have struggled for years to encapsulate, modify, or somehow protect protein (or polypeptide) products taken orally from degrading this way. They've never succeeded. That's why, for instance, growth hormone (a polypeptide) remains an injection, not an oral agent. An oral growth hormone, by the way, would sell like mad, so the drug companies would very much like to figure out how to bypass the degradative effects of stomach acid. One of the "researchers" behind the nattokinase claims boasts that he has single-handedly figured out how to protect the nattokinase molecule in the gastrointestinal tract. However, he won't tell anybody how he does it. Right. --Fibrinolytic agents are extremely dangerous. In years past, we used to treat heart attacks with intravenous fibrinolytic agents like tissue plasminogen activator, urokinase, streptokinase, and others. They have fallen by the wayside, for the most part, because of limited effectiveness and the unavoidable dangers of their use. Fibrinolytics are "dumb": they dissolve blood clots in both good places and bad. While they might dissolve the blood clot causing your heart attack, they also degrade the tiny clot in your cerebral (brain) circulation that was protective. That's why fatal brain hemorrhages, bleeding stomach ulcers, and blood oozing from strange places can also occur with fibrinolytic administration. Believe me, I've seen it happen, and I've watched people die from them. The idea that a small dose taken orally is healthy is ridiculous. Even if nattokinase worked, why the heck would you take an agent that has known dangerous and very real consequences?Don't let this idiocy reflect poorly on the K2 conversation, which, I believe, holds real merit and is backed by legitimate science. This is symptomatic of a larger difficulty with the supplement industry: Insane and unfounded claims about one supplement erodes credibility for the entire industry. It gives regulation-crazed people like the FDA ammunition to go after supplements, something none of us need. You and I have to sift through the nonsense to uncover the real gems in this rockpile, real gems like vitamin D3, omega-3 fatty acids from fish oil, and, perhaps, vitamin K2. But not nattokinase.
Blood pressure with exercise 27. April 2007 William Davis (10) Here's a frequently neglected cause for an increasing CT heart scan score: High blood pressure with exercise. Let me explain.Paul's blood pressure at rest, sitting in the office or on arising in the morning, or at other relatively peaceful moments: 110/75 to 130/80--all in the conventional normal range. We put Paul on the treadmill for a stress test. At 10 mets of effort (on the protocol used, this means 3.4 mph treadmill speed at 14 degree incline), Paul's blood pressure skyrockets to 220/105. That's really high. Now, blood pressure is expected to increase with exercise. If it doesn't rise, that's abnormal and may, in fact, be a sign of danger. Normally, blood pressure should rise gradually in a stepwise fashion with increasing levels of exercise. But any blood pressure exceeding 170/90 is clearly too high with exercise. (Not to be confused with high blood pressures not involving exercise.) A handful of studies have suggested that a "breakpoint" of 170/90 also predicts heightened risk of heart attack over a long period.)I see this phenomenon frequently--normal blood pressure at rest, high with exercise. This also suggests that when Paul is stressed, upset, in traffic congestion, under pressure at work, etc., his blood pressure is high during those periods, as well. I wouldn't be surprised to see other phenomena of underappreciated high blood pressure, like abnormally thick heart muscle (left ventricular hypertrophy), an enlarged thoracic aorta (visible on your heart scan), left atrium, perhaps even an abnormal EKG or abnormal kidney function (evidenced by an elevated creatinine on a standard blood panel). Unfortunately, the treatments that reduce blood pressure are "stupid," i.e., they have no appreciation for what you are doing and they reduce blood pressure all the time, whether or not you're stressed, exercising, or sleeping. Blood pressure reduction should begin with weight loss, exercise, reduction of saturated fats and processed carbohydrates (esp. wheat), magnesium replacement, vitamin D replacement. Think about CoQ10. After this, blood pressure medication might be necessary. The message: Watch out for the blood pressures when you have a stress test. Or, if you have a friend who is adept at getting blood pressures, get a blood pressure immediately upon ceasing exercise. It should be no higher than 170/90.
Vitamin D2 vs. vitamin D3 26. April 2007 William Davis (21) An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well. Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure. The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably. However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol. Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children. D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness. 25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.
Unexpected effects of a wheat-free diet 17. September 2009 William Davis (59) Wheat elimination continues to yield explosive and unexpected health benefits. I initially asked patients in the office to eliminate wheat because I wanted to help them reduce blood sugar and pre-diabetic tendencies. A patient would come to the office, for example, with a blood sugar of 118 mg/dl (in the pre-diabetic range) and the other phenomena of pre-diabetes or metabolic syndrome (high blood pressure, high inflammation/c-reactive protein, low HDL, high triglycerides, small LDL), and the characteristic wheat belly. Eliminate wheat and, within three months, they lose 30 lbs, blood sugar drops to normal, blood pressure drops, triglycerides drop by several hundred milligrams, HDL goes up, small LDL plummets, c-reactive protein drops. People also felt better, with flat tummies and more energy. But they also developed benefits I did not anticipate:--Improved rheumatoid arthritis--I have seen this time and time again. Eliminate wheat and the painful thumbs, fingers, and other joints clear up dramatically. Many former rheumatoid sufferers people tell me that one cracker or pretzel will trigger a painful throbbing reminder that lasts a couple of hours. --Improved ulcerative colitis--People incapacitated with pain, cramping, and diarrhea of ulcerative colitis (who are negative for the antibodies for celiac disease) can experience marked improvement. I've seen people be able to stop all their nasty colitis medications just by eliminating wheat. --Reduction or elimination of irritable bowel syndrome--Reduction or elimination of gastroesophageal reflux--Better mood--Eliminating wheat makes you happier and experience more stable moods. Just as wheat is responsible for a subset of schizophrenia and bipolar illness (this is fact), and wheat elimination generates dramatic improvement, when you or I eliminate wheat, we also experience a "smoothing" of mood swings. --Better libido--I'm not sure whether this is a consequence of losing a belly the size of a watermelon or improvement in sex hormones (esp. testosterone) or endothelial responses, but more interest in sex typically develops. --Better complexion--I'm not entirely sure why, but various rashes will often dissipate, bags under the eyes are reduced, itching in funny places stops.It's also peculiar how, after someone eliminates wheat for several months, re-exposure of an errant cracker or sandwich results in cramping and diarrhea in about 30% of people. Obviously, people with celiac disease, who can even die of exposure to wheat, are even worse. What other common food do you know of that makes us sick so often, even occasionally with fatal outcome?
Is Lp(a) part of your legacy to your children? 15. September 2009 William Davis (21) If you have lipoprotein(a), Lp(a)--the most aggressive known cause of heart disease that no one has heard of--then you need to tell your children. Lp(a) is a "cleanly" inherited genetic pattern: If either parent has it, there's a 50% chance that you have it. If you have it, then there's a 50% likelihood that each of your children has it. (Note that each child experiences a likelihood of 50%, not 50% of your children. This is because each child is conceived as an independent statistical event. So much for romance!)The atherogenicity (plaque-causing potential) of Lp(a) also tends to get transmitted. In other words, if your Dad had a heart attack at age 50 due to Lp(a) and you share Lp(a), then you likely share a similar magnitude of risk as your Dad. If your Mom had Lp(a), though passed quietly at age 89 without any overt evidence of heart disease, then you are likely to share the relatively benign form of Lp(a). For most of us with Lp(a), however, it is best to assume that it has at least some potential for causing heart disease, being the most aggressive cause known. (That is, until we have the ability in everyday clinical practice to characterize Lp(a) by assessing such factors as the size of the apoprotein(a) molecule, the number of kringle "repeats" on the tail, etc. Until then, we need to rely on the crude, though helpful, observation of family history.) At what age should you inform your children? There's no hard-and-fast rule. However, I generally suggest to patients that they talk about Lp(a) with their children when they reach their 20s or 30s, old enough to begin to understand the implications and begin to think about adopting healthier lifestyles. Is treatment required at, say, age 35? That depends on the pattern of Lp(a)-related heart disease in the family: With exceptionally aggressive forms, it might be reasonable to begin treatment at this relatively early age.
Do "Heart Healthy" sterols cause heart disease? 9. September 2009 William Davis (19) The sterol question continues to pop up.Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia? Below, I've reprinted a previous Heart Scan Blog post on sterols. Sterols should be outlawedWhile sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:Higher blood levels of sterols increase cardiovascular events:Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.Sterols can be recovered from diseased aortic valves:Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.Sterols are incorporated into carotid atherosclerotic plaque:Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.Though the data are mixed:Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.No association between plasma levels of plant sterols and atherosclerosis in mice and men.The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:Each Nature Valley Healthy Heart Bar contains 400 mg sterols.HeartWise orange juice contains 1000 mg sterols per 8 oz serving.Promise SuperShots contains 400 mg sterols per container.Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.Kardea olive oil has 500 mg sterols per 14 gram serving.WebMD has a table that they say can help you choose "foods" that are sterol-rich.In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products. Some more info on sterols in a previous Heart Scan Blog post: Are sterols the new trans fat? .
Why obese people can't fast 9. September 2009 William Davis (21) Why do obese people claim it is impossible to fast?Most overweight people are terrified at the prospect of facing any period of time without ready access to food. Persuading them to begin a program of intermittent fasting is a hopeless cause. They just refuse. Contrary to popular opinion, this is not just glutonny at work. It is the effect of what I call "the cycle of hunger," the 2-hour up and down cycle of rising sugar and insulin, followed by their inevitable fall. The precipitous fall of sugar and insulin triggers mental fogginess, fatigue, and insatiable hunger. (By the way, this is the same phenomenon underlying the silly notion of "grazing.") According to an LA Times article, fasting may be difficult to impossible for some people: "Ruth Frechman, a registered dietitian in Burbank and spokeswoman for the American Dietetic Assn., says she frequently sees such extreme strategies backfire. 'You're hungry, fatigued, irritable. Fasting is not very comfortable. People try to cut back one day and the next day they're starving and they overeat.'" (Not surprising, coming from the American Diatetic Assn. They, along with such agencies as the American Diabetes Association, are vocal proponents of low-fat, high-carbohydrate, "healthy whole grain" diets--you know, the diets that make us fat and diabetic.)Ms. Frechman is correct: Having someone engage in a period of fasting, no matter how brief, when the diet leading up to the fast is filled with "healthy whole grains" and other carbohydrates will result in painful hunger that eventually overcomes any effort. A period of overeating typically follows the aborted attempt. Fasting cannot work as long as the 2-hour cycle of hunger continues. The first step: Eliminate the 2-hour cycle of hunger by dramatically reducing or eliminating carbohydrates. Our preferred method is to eliminate wheat, cornstarch, and sugars. (Just be aware of wheat withdrawal, the fatigue that develops in the first 5 days after wheat elimination that affects up to 30% of people.)Once wheat, cornstarch, and sugars are eliminated, hunger reverts to that of physiologic need--appetite will be smaller and less intense, since it is driven by your body's needs, not by abnormal stimulation from wheat, cornstarch, and sugar. The fear of not having food dissolves, the 2-hour cycle of mental fogginess, fatigue, and hunger will be gone. Intermittent fasting is a wonderful strategy for reducing weight; gaining control over lipids, lipoproteins, and coronary plaque; regaining appreciation for food; reducing appetite. But it's not even worth trying unless you've already eliminated the unnatural appetite triggers that will booby-trap any fasting effort.
Test your own thyroid 7. September 2009 William Davis (15) 134 people responded to the latest Heart Scan Blog poll:When I ask my doctor to test my thyroid, he/she: Accommodates me without question 45 (33%)Questions why, but orders the tests 49 (36%)Refuses because you seem "healthy" 20 (14%)Refuses without explanation 4 (2%)Ridicules your request 16 (11%)That's better than I anticipated: 69% of physicians complied with this small request. After all, you're not asking for major surgery. You're just asking for a very basic test, as basic as a blood count or electrolytes. 36% of respondents said that their doctor asked why, but still complied; this is simply practicing good medicine--If there is a problem, your doctor would like to know about it.However, the remainder--31%--were refused in one way or another. Incredibly, 11% were ridiculed.Although this was not asked in the poll, I believe that it is a safe assumption that you asked with good reason: you're abnormally fatigued, you have been gaining weight for no apparent reason or can't lose weight despite substantial effort, or you feel cold at inappropriate times.Let's say you're tired. Ever since last summer, you've suffered a gradual decline in energy.So you ask your doctor to assess your thyroid. He refuses. "You're just fine! There's nothing wrong with you."You disagree. In fact, you are quite convinced that there is something physically wrong. What do you do?You could:--Drink more coffee--Exercise more in the hopes that it will snap you out of your lethargy--Sleep more--Take stimulants of various sortsOr, you could get your thyroid assessed and settle the issue. But how can you get this done when your doctor won't accommodate you, even though you have perfectly fine health insurance and are simply interested in feeling better and preserving your health?You could test your thyroid yourself. This is why we're making self-testing kits available. Test kits are available here. This is yet another facet of the powerful revolution that is emerging: Self-directed health.
Trains, planes, and heart scans 4. September 2009 William Davis (10) A Heart Scan Blog reader posted the following question:It is not clear to me why getting a cardiac scan is the necessary first step, if in fact the next step would be to bring down small LDL particles which is revealed on a NMR lipoprofile or VAP test. Why isn't the NMR or VAP test the first thing?Good question. Think of it this way:Lipoproteins, as measured via VAP (Vertical Auto Profile) or NMR (Nuclear Magnetic Resonance), provide a snapshot of risk from a metabolic viewpoint at that moment. Lipoproteins shift with the tides of age, menopause, weight changes, even what you ate last evening for dinner (especially small LDL). There are also other factors that cause coronary plaque, as well, not revealed through lipoprotein testing, such as vitamin D deficiency, smoking, high blood pressure, phosopholipase A2, lipoprotein(a), inflammatory factors, thyroid dysfunction, omega-3 fatty acid deficiency, etc. A heart scan, providing a coronary calcium score, provides an indirect measure of coronary plaque that is the sum total of lipoprotein and other plaque-causing factors that have accumulated up to the time of your scan--regardless of the cause.It means that two females, each 60 years old, with 70% small LDL, HDL 42 mg/dl, triglycerides 150 mg/dl, and mild hypertension, have identical markers for potential coronary risk, but can have widely different heart scan scores. One might have a score of zero, while the other might have a score of 300. Why would the same panel of causes measured at one moment yield wildly different quantities of plaque? Several reasons:1) The lifestyles, eating habits, and weight of each woman differed during their earlier years, not currently reflected in this moment's lipid or lipoprotein patterns. Perhpaps one experienced several years of extraordinary stress from a failed marriage, or suffered through two years of depression that caused her to smoke and overeat. 2) There are hidden factors that affect coronary plaque growth that we are presently not able to detect, e.g., vitamin D receptor genotype, cholesteryl-ester transfer protein variants, variation in inflammatory factors. If we can't measure it, we won't know whether it might influence coronary plaque risk. With all the changes that occur over a person's life, with the uncertainties of yet-to-be-identified causes for coronary plaque, how can you possible know what your risk for heart disease truly is? Yup--a heart scan. Do it and you will know.
D2 and D3 are two different things 3. September 2009 William Davis (15) Helena posted this instructive comment in response to the Heart Scan Blog post, Weight loss and vitamin D. It illustrates the confusion common among physicians and pharmacists on the differences between D2 and D3. (Edited slightly for clarity.)Not many weeks ago a colleague of mine (let’s call him Eric) asked me if I knew the difference between D2 and D3 and I told Eric that D2 comes from irradiated mushrooms and D3 comes from wool. In other words, D3 is the same kind of vitamin as humans get from the sun. Humans just don’t get enough and we can’t produce it on our own, like the sheep can. (D3 is natural for humans, D2 is not.)After telling Eric this, he asked me how he would know what he is taking and I gave him the medical definitions of them both (D2 = Ergocalciferol; D3 = Cholecaliciferol). Since I was aware that he had gotten his Vitamin D by prescription, I told him “I am 99.9% sure that you are taking D2, but I would be thrilled to find out I am wrong.” Eric called his pharmacy right away and got the answer I was expecting: ergocalciferol. On confronting the person Eric was talking to, the answer he got back was that Ergocalciferol is the only Vitamin D they are giving out. A week later, Eric had a new appointment with his doctor and decided to ask him about the D2/D3 issue. The doctor said he knew that there was a difference in them both, but could not say what, not even the basic facts I mentioned above. But the doctor stamped a post-it with what he had sent to the pharmacy just to show Eric. “Vitamin D3; 50,000IU tab” is what the stamp said. Eric, off course, got confused and was starting to believe that the pharmacy had made a mistake by giving him Ergocalciferol (D2) since the doctor had given him D3, or at least that is what was stamped on the little note he had. Today, after getting a refill of his Vitamin D he also got and kept all his paperwork that came along with it. Still believing that stamp the doctor had given Eric earlier, he asked me to double and triple check that my definition of D2 and D3 was correct. I did, just for my own sanity, and I was still right. One of the sheets Eric brought me today was the “Patient Education Monograph” sheet stating the drugs and how to use it and so on. The thing that jumped out the most to me was this: Generic Name: Vitamin D – OralCommon Brand name(s): Drisdol, Maximum D3Identification: PA140 Green Oval CapsuleThis is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: ErgocalciferolMy researching mind went into high concentration mood and I started to dig. And this is what I found: The brand name Drisdol is Ergocalciferol (D2), not D3. The Brand name Maximum D3 seems to be hard to find out there in cyber space as a brand name. But the ones I found that were called Maximum D3 seems to be the real stuff, however none of them required a prescription. When trying to find out through the identification number on the pills (PA140) I now know for sure that Eric is taking Vitamin D2 and not the preferred Vitamin D3. The brand name, Drisdol, had the identification W on one side and D92 on the other, but it is still Ergocalciferol. The only conclusion I can draw from all this is that the medical industry does not know or care about the difference in D2 and D3 – it is all same to them. And as long as the pharmacies only give out D2 it does not matter what the doctor prescribe anyway. I know that people are most likely to be prescribed a D2 pill than to be told to buy over-the-counter D3. But it was almost heart breaking to see the letter D and number 3 right next to the drug Drisdol, as we know is a D2 vitamin. It just didn’t make sense to me that they can be labeled as the same type of medication, when we know it is not! Incredible.Why prescribe plant form D2 when you can get perfectly reliable, safe, effective D3--the human form, at the health food store for about $6? Once again, it's the peculiar false bias of physicians and pharmacists: If it's prescription, it must be good; if it comes from a health food store, it must be bogus. Humans need human vitamin D. Plain and simple.For more on the D2 vs. D3 issue, see the Heart Scan Post, The case against vitamin D2.
Weight loss: Different causes, different solutions 1. September 2009 William Davis (8) Heart Scan Blog reader, Kris, related this enlightening story of weight loss (slightly edited for clarity).Kris learned that excess weight is gained through multiple causes. The solutions are therefore multiple, not just one change in diet or two. I started studying about my thyroid issue much earlier and did lose some weight. But ever since I started following Dr. Davis’s blog, it has given me confidence that I was on the right track. I did have my thyroid and iodine figured out from other sources, but Dr. Davis helped me to understand the issues with not only the thyroid but vitamin D3, fructose, fish oil, niacin, wheat etc. I have lost 43lb in last 14 months. It seems to me that there are certain percentages of weight connected with different issues. For example, after I gave up alcohol and sugar, I lost about 14lbs from total weight of 243lbs, weight came down to about 229lb. Then it stopped at 229lb, even though I was in the gym almost 5 to 6 days a week with full workouts. After I changed my thyroid medication to natural thyroid hormones (took synthetic T4 for over 10 years), the weight dropped down further 13lbs or so in matter of few days, shape of the face changed from moon shape/double chin to ordinary long face. Then it kind of stopped at around 213-216 lbs. After giving up wheat, reducing carbs, increasing protein intake (whey protein, chicken etc. no soya, no fructose) the weight came down another 14lbs. Now it is around 200-202lbs and I am over 6.2 tall with heavy set of bones. I feel better than I have ever in my life. More stamina, more clarity/no fog, more confidence and 99% of the time relaxed and being able to see the situation from multiple angles. I use to be able to drink a liter or more jack denial without a problem in one evening but now can’t stand half a can of beer (I miss JD). Drinking alcohol makes me sick. I sleep well and if I wake up in the middle of the night, I have no problem going back to sleep. No more out of breath stair climbing at all. One other thing: I used to be the most attractive meal to the mosquitoes, but not anymore. This year I haven’t been bitten once. I take my dog to the park everyday and I do not use any mosquito repellent, what a relief. I don’t know if it is because of thyroid, iodine, wheat or something else. Skin texture has changed dramatically. I do not use full soap or shampoo, 20% borax, 10 percent of my soap or shampoo for scent and rest water, mixed in a 500ml bottle. No more dandruff, dry skin, pimples for me. Dr. Davis I am thankful to people like you who have the ability to see beyond what you have been taught and have the guts to say the way it is. Most of us work to make living on daily basis but some make their living while spreading their knowledge to save lives. Dr Davis you are one of those few people. Please keep it going.
Calling all losers! 29. August 2009 William Davis (14) I'd like to invite anyone who has followed the Track Your Plaque Break the Weight Barrier program to consider posting their stories and photos on the Heart Scan Blog. Because our focus is prevention and reversal of coronary heart disease, we have not made an effort to catalog the weight loss experience that people have while on the program. For many, weight loss has been substantial. (Several people this week alone have reported weight loss of 9 to 46 lbs in the past 6 months.)It would be helpful to hear and see these results. For those of you who don't mind having a story and photo on this Blog, please come back in future to post your results. You will find this post by entering "weight loss" into the site-specific search bar at the top of the page.
Weight loss and vitamin D 28. August 2009 William Davis (28) At the start of her program, Penny's 25-hydroxy vitamin D blood level showed the usual deficiency at 22 ng/ml. She supplemented with 8000 units of vitamin D. Another 25-hydroxy vitamin D blood level several months later showed a level of 67.8 ng/ml, right on target. But Penny also began our diet, including the elimination of wheat, cornstarch, and sugars, and, over 6 months, lost 34 lbs. Now a much trimmer 146 lbs (still more to go!), another vitamin D blood level: 111 ng/ml. Penny's weight loss means that the vitamin D is distributed in a smaller total volume, particularly a lower volume of fat. This is a common phenomenon with substantial weight loss: lose weight and the need for vitamin D is reduced. The reduction in dose is roughly proportion to the weight lost. Vitamin D should therefore be reassessed with any substantial change in weight of, say, 10 lbs or more, either up or down, because of the influence of fat on vitamin D blood levels. Some references on this effect:Men and women over age 65:Adiposity in relation to vitamin D status and parathyroid hormone levels: a population-based study in older men and women.Obese women:Low 25-hydroxyvitamin D concentrations in obese women: their clinical significance and relationship with anthropometric and body composition variablesObese children:Hypovitaminosis D in obese children and adolescents: relationship with adiposity, insulin sensitivity, ethnicity, and season.African-Americans:Relationship of vitamin D and parathyroid hormone to obesity and body composition in African Americans.Although the bulk of the effect is most likely due to sequestration by fatty tissue, perhaps less sun exposure in obese people also contributes:Body mass index determines sunbathing habits: implications on vitamin D levels.
