Near-fatal brush with nattokinase 14. April 2010 William Davis (0) Here is precisely why I have spoken out against nattokinase: People may put faith in this "supplement" when there are virtually no data to support its use in such dangerous conditions as pulmonary embolism. Pulmonary embolism occurs when a large volume of blood clots in the veins of the pelvis, abdomen, and into the legs. A clot breaks off and lodges in the pulmonary arteries of the lungs. This can be fatal within minutes to hours, the victim struggling to breathe, since oxygen is not transferred to the blood and it causes terrible pain in the chest. The treatments are fairly obnoxious: intravenous anticoagulants (blood thinners), followed by oral blood thinners like warfarin. While they carry risk of bleeding and other long-term risks, it's better than dying. Would you bet that a "nutritional supplement" manufacturer's vague claims and lack of data are sufficient proof to treat a life-threatening condition? You're a fool if you are. Anyone reading these pages knows that I am a vigorous supporter of nutritional supplements. I even consult for the nutritonal supplement industry. But I am also an advocate of TRUTH, not BS. Here is a woman from England who inquired whether she should stop her husband's warfarin in favor of nattokinase. This is precisely the sort of thing that can happen because of the campaign of misinformation behind nattokinase. Dr. Davis,Thank you for your very interesting blogs, which I came across searching for natural alternative treatments to warfarin. My husband has been following the low carb, high fat, real food regime over the past few years. He got off all the blood pressure and cholesterol drugs and never felt better. He even got his blood sugar down from a recorded high that we are aware of 13 nmol/L (234 mg/dol) to 6.1 nmol/L 109.8 mg/dl). We were on holiday in the Caribbean. Just before our return home, we did a trip to a neighbouring island that included non-alcoholic fruit punches. They tasted great, but were very sweet. I broke my normal refusal to drink these things, but only had a couple of glasses. (After all, we were on holiday!) My husband believes he consumed around 1.5 litres of the stuff and now realises he was feeding his body a very toxic product – fructose. That night, he had an incredible toxic response and we only got him onto the plane with a visit to the hospital and a pain killer injection. The symptoms of pulmonary embolism only showed 2 weeks later . . . and warfarin treatment was started. We would both like to use an alternative therapy if we can find someone with experience to provide the support.Do you know of any studies that support alternative options?Do you know of any practitioners in the England who support a non-drug approach with an understanding of nutrition who we may be able to receive advice and support?FBYork, England
Glucophobia: The Novel 13. April 2010 William Davis (25) Just kidding: No novel here. However, there is indeed a story to tell that should scare the pants off you. If you haven't yet gathered that carbohydrates are a macronutrient nightmare, let me recount the list:Carbohydrates increase small LDL particlesOr, in the cholesterol-speak most people understand, "carbohydrates increase cholesterol." It's counterintuitive, but carbohydrates increase LDL substantially, far more than any fat. Carbohydrates increase blood sugarEggs don't increase blood sugar, nor do chicken, raw almonds, onions or green peppers. But a bowl of oatmeal will send your blood sugar skywards. Carbohydrates make you fatCarbohydrates, whether in the form of wheat flour in your whole wheat bread, sucrose in your ice cream, fructose in your "organic Agave nectar," or high-fructose corn syrup in your dill pickles. They all provoke de novo lipogenesis, or fat formation. They also stimulate insulin, the hormone of fat storage. Carbohydrates cause glycationHigh blood sugar, like the kind that develops after a bowl of oatmeal, triggers glycation, or modification of proteins by glucose (blood sugar). This is how cataracts, kidney disease, and atherosclerotic plaque develop. Small LDL is 8-fold more glycation prone than large LDL, providing a carbohydrate double-whammy. Your glucose meter remains the single best tool to gauge the quality of your diet. Many people have horror stories of the shocking experiences they've had when they finally get around to checking their postprandial glucose.
Drama with the Dr. Oz Show 11. April 2010 William Davis (27) A producer from the Dr. Oz show recently contacted my office. They asked whether we could supply them with a volunteer patient from either my practice or the Track Your Plaque program who would be willing to appear on the show and discuss heart disease prevention. They needed someone to commit within 24 hours. Despite the short notice, we identified a volunteer. He flew to New York the following week where he was interviewed along with several other men and women, all of whom had heart disease (heart attacks, stents, etc.). However, as this young man is very slender and follows most of the Track Your Plaque principles (e.g., vitamin D and omega-3 fatty acid supplementation; no wheat, cornstarch, or sugars, no restriction of fat, etc.), he apparently received less attention than the overweight, I-know-nothing-about-diet interviewees. Then there was an odd turn of events: Dr. Dean Ornish, apparently a friend of Dr. Oz, will be providing the dietary counseling. The producer had made no mention of Dr. Ornish. Now that's an odd collision of philosophies: Our Track Your Plaque version of low-carb with the guru of low-fat, Dr. Ornish. The following week, Dr. Ornish called me and graciously asked whether I was okay with this. I'm not sure just how much he knew about the philosophy I advocate, nor how much I have bashed his program as a destructive approach to diet, nor whether he knew that I gained 30 lbs on the Ornish diet, along with a drop in HDL to 27 mg/dl, increased triglycerides to 350 mg/dl, and type II diabetes that I've talked about on this blog and the Track Your Plaque book and website. I suspect he knew little to none of this. Anyway, I tried to diplomatically explain that my patient's cause for coronary plaque was small LDL particles that he expressed despite his very slender build, likely from excessive carbohydrates, controlled with carbohydrate restriction. Dr. Ornish maintained his usual arguments: Grains are good, provided they are whole grains, heart disease is "reversed" with his diet program, etc. (I didn't want to challenge him in a phone call and tell him that he never actually reversed coronary plaque, but just reversed endothelial dysfunction. But, as Dr. Ornish is not a cardiologist, I wasn't sure how far his understanding of these issues went.) We agreed to disagree. This leaves my poor patient in an odd position: Being asked by Dr. Ornish and the Dr. Oz show to follow a low-fat program for the sake of entertainment, or adhering to the advice we follow that has so far served him well, given his small LDL particle size tendencies. We'll see where this little drama leads.
Response from Nature Made 10. April 2010 William Davis (31) Here's the response from Nature Made when I emailed them about my concern that there appears to be no vitamin D in their vitamin D gelcaps. It is the usually CYA corporate-speak that says nothing. The grammatical errors make it clear that this was a "canned" response. Date: April 9, 2010From: Marissa Reyes, Consumer Affairs DepartmentSubject: Reference #346236Dear William Davis, MD:We recently received your e-mail regarding Nature Made products. We regret to hear that the quality standards of our company. [?]Our company is called Pharmavite, and we manufacture Nature Made nutritional supplements. We have been in business since 1971. We are committed to quality control, and have very high quality standards. Our Quality Control personnel sample and test all raw materials as they enter our plant, and again assay the finished product, before final packaging. Dietary Supplements are regulated under the FDA through DSHEA (Dietary Supplement Health & Education Act of 1994). The United States Pharmacopoeia (USP) establishes standards for the composition of drugs and nutritional supplements. This voluntary non governmental organization was set up in 1820 and has officially been recognized by federal law since 1906. Standards established by USP for products are legally enforceable by the FDA. At Pharmavite we participate in the USP Dietary Supplement Verification Program (DSVP). Many of our products have earned the DSVP seal and additional products are currently being evaluated. Our DSVP certified products will have the DSVP seal on the product label.Our Nature Made Vitamin D 400 IU tablets have been reviewed by the USP and bears the DSVP symbol on the label. Although the USP has not reviewed all of the Nature Made Vitamin D supplements, all of our products go through the same rigorous quality testing at Pharmavite. The products which have earned the seal help us to demonstrate the high quality of our products. We would like to look into the product(s) your patients have been using. If you could provide the UPC and lot numbers of the product(s), we will be happy to review our records. In addition, if you would like us to test the product(s) that you currently have, we will be pleased to send a prepaid postage mailer so you may return the product(s) to us so that our Quality Control Department can examine it. Please let us know if you would like us to send you the prepaid postage mailer. We thank you for contacting us and hope that you will continue to use and enjoy Nature Made products with complete confidence.Sincerely,Marissa ReyesConsumer Affairs CoordinatorPharmavite, LLCMR:346236-10Patients who come to the office do not provide me with the bottles nor lot numbers. In past, when I've gone to the trouble of doing this (with other companies, not Nature Made), it has come to nothing helpful. The information gets passed on to the company and we hear nothing and never learn if there was a problem, or receive some more corporate-speak letter saying everything was fine. This is obviously a liability-avoidance tactic: Admitting that something was wrong would open them up to legal risk. So, frankly, I can't be bothered. So we are left with the unsatisfying experience of relying on street-level experiences. For now, my advice: Avoid Nature Made vitamin D. Too many people have had blood tests demonstrating that they are not obtaining any vitamin D. By the way, the Nature Made brand of fish oil is among the very few problem brands of fish oil we've encountered. Fish oil should be only mildly fish in smell and generally should not cause stomach upset and excessive belching if properly purified. Nature Made is excessively fishy when you smell it, suggesting oxidation. We've had repeated (dozens) of patients who have experienced difficulties with this brand. Rather than dealing with the frustrating gobbledy-gook of this company, just avoid their products.
What to Eat: The diet is defined by small LDL 9. April 2010 William Davis (15) I approach diet from the perspective of small LDL particles. Small LDL particles have exploded in frequency and severity in Americans. It is not at all uncommon to see 70% or more small LDL particles (i.e., 70% of total LDL particle number or Apo B) on lipoprotein testing. (I saw two people today who began with over 95% small LDL.)Small LDL particles are:--More likely to persist in the bloodstream longer than large LDL particles. --More likely to adhere to components of atherosclerotic plaque. --More likely to gain entry to plaque.--More likely to be taken up by inflammatory white blood cells which, in turn, become the mast cells that fill coronary plaque. --More likely to be oxidized. --More likely to be glycated (8-fold more likely than large)To add insult to injury, foods that trigger small LDL formation--i.e., carbohydrates--also cause high postprandial blood sugars. High postprandial blood sugars, in turn, glycate small LDL. That combination of events accelerates 1) plaque growth, 2) plaque instability, and 3) aging. So carbohydrates trigger this sequence, carbohydrates of all stripes and colors. Not just "white" carbohydrates, but ALL carbohydrates. It's all a matter of degree and quantity. So, yes, even quinoa, bulghur, and sorghum trigger this process. I've only recently appreciated just how bad oats and oatmeal are in this regard--really bad.Foods that trigger small LDL also trigger higher blood sugars; foods that trigger higher blood sugars also trigger small LDL. Small LDL and blood sugar are two different things, but they track each other very closely. So, in the Track Your Plaque approach to diet, we craft diet based on these simple principles:1) Eliminate wheat, cornstarch, and sugars--These are the most flagrant triggers of small LDL, blood sugar, and, therefore, LDL glycation. 2) The inclusion of other carbohydrates, such as oatmeal, quinoa, rye, etc. depends on individual sensitivity. Individual sensitivity is best gauged by assessing one-hour postprandial glucose. Stay tuned for more in this series. Also, Track Your Plaque Members: We will be having an in-depth webinar detailing more on thees principles in the next couple of weeks.
Is it or isn't it vitamin D? 7. April 2010 William Davis All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in 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. With freedom comes responsibility. Otherwise, you might be looking for love . . .oops, I mean health . . . in all the wrong places. Track Your Plaque APB 9. 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 Toggle navigation Home Blog Home Archive Join Now Se connecter Do stents prevent reversal? 27. janvier 2007 William Davis (3) I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents. Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent? These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all. At what score should I have a heart cath? 25. janvier 2007 William Davis (0) This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization? In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow. But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly. Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit. Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved. In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms. Niacin makes NY Times 24. janvier 2007 William Davis (0) In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again. (Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)Among their comments:...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.It is niacin, the ordinary B vitamin.In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets. Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver." Wheat: the nicotine of food 24. janvier 2007 William Davis (1) Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes. What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie? Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away. But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc. Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite. Good time for a heart attack? 22. janvier 2007 William Davis (0) Man Has Heart Attack At Right Place, Right Time If Robert Ricard had picked the wrong restaurant for lunch, he might have died.The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.Luckily, a disaster medical team was sitting nearby.A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another. What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path. Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place. How good is the South Beach Diet? 21. janvier 2007 William Davis (2) I'm a fan of the South Beach Diet. Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine. Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains. Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu. (From The South Beach Diet, Dr. Arthur Agatston) There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster. But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins. The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables. What really makes South Beach special, however, are its clever recipes. Dr. Arthur Agatston (the author) involved chefs from the restaurants in the South Beach area of Miami to help create healthy yet delicious recipes. We've tried many of them and, while they are different from traditional fare, are delicious and satisfying for the most part.Criticisms? None, really. But, when my patients choose South Beach (which I often encourage), I often have to impress on them that the Track Your Plaque program is not about weight loss. It is about seizing control of a potentially life-threatening disease. It is a far more important goal with greater implications. Weight loss is just one aspect of a coronary plaque control effort. For this reason, we sometimes have to make changes in the South Beach program to allow for correction of specific lipoprotein patterns. The most common modification is in people with small LDL particles. This pattern often does indeed respond to weight loss and/or niacin. However, it occasionally persists despite these efforts. We then will ask the patient to continue to restrict the re-introduction of wheat products, though it is allowed after Phase I in South Beach. In other words, for this specific and sometimes difficult to control lipoprotein pattern, a spedific modification of the off-the-shelf South Beach program is sometimes necessary. Of course, the diet is created to suit everybody. Lipoprotein analysis permits detailed insight into your patterns and it's only to be expected that specific modifications might be needed. But, as written, you can do quite well in your plaque control program by sticking to South Beach. Be patient with niacin 19. janvier 2007 William Davis (0) Mel's HDL started at 37 mg/dl one year ago. Mel had several other abnormal lipoprotein patterns along with his HDL (inc. small LDL and Lp(a)), but HDL was clearly a crucial factor in his panel. With a heart scan score of 1166, we needed to raise Mel's HDL to the Track Your Plaque target of 60 mg/dl. So Mel started niacin, our number one method to raise HDL, in addition to reducing his exposure to wheat products and other high glycemic index foods; increasing his physical activity; trying to reduce his excess tummy fat; fish oil; dark chocolate (2 oz per day) and red wine (1-2 glasses per day, preferably dark French reds). The form of niacin we often choose is SloNiacin (Upsher Smith), available over-the-counter for about $12-14 per 100 tablets.Mel started out with niacin 500 mg per day at dinner, increased to 1000 mg at dinner after four weeks. Although this is usually too soon to reassess HDL, Mel insisted. His HDL 41 mg/dl. Mel's disappointment was palpable. He was the usual type A personality: he wanted his HDL higher--now! So Mel insisted that we increase niacin to 1500 mg per day. (We never go higher than this if low HDL or small LDL is the indication for niacin; only when Lp(a) is present do we go higher.)Six months into this process, HDL: 45 mg/dl. Still a sluggish response. One year later, HDL: 68 mg/dl. Finally!That is typical for niacin, as well as combination of lifestyle changes Mel made. None of them result in an immediate rise in HDL; all take months to 1-2 years to exert full HDL-raising effect. Think of HDL as the 82-year old grandma who takes a long time to cross the street-she does get there!Note: Doses of niacin >500 mg per day should be taken with medical supervision. Can vitamin D be a SOLE risk factor? 18. janvier 2007 William Davis (6) Here's a crazy question. It occurred to me as I was talking to Drew, a slender, active 54-year old dentist with no bad habits including no smoking. Drew's heart scan score was 222. His lipoprotein analysis mostly revealed a lot of nothing, which is unusual. The only pattern that showed up was a modestly high LDL of 122 mg/dl with a very slight excess of small LDL. That's it. I would not be satisfied that these were sufficient cause for Drew's level of coronary plaque. Drew's 25-OH-vitamin D3 level: 15 ng/ml--severe deficiency--despite the fact that his doctor had suggested that he take a vitamin D2 preparation. In other words, Drew had been profoundly deficient, probably for years.Given the unimpressive cholesterol and lipoprotein values, could vitamin D serve as a trigger for coronary plaque all by itself? I don't have an answer and know of nobody else who does. However, my opinion is that vitamin D is indeed a potent risk that can cause heart disease as a sole risk factor. Perhaps it's another piece of circumstantial evidence suggesting that vitamin D has an enormous influence on health, including coronary plaque. Interestingly, the only other health problem Drew has had is prostate cancer, treated a few years ago with prostate removal and radiation. Good evidence suggests that vitamin D deficiency escalates risk of prostate cancer substantially. By the way, I've seen people taking vitamin D2 preparations, called "ergocalciferol," who are every bit as deficient as those who take no vitamin D at all. Avoid D2 or ergocalciferol preparations: they're worthless. Does fish oil raise LDL cholesterol? 17. janvier 2007 William Davis (1) Katie had an LDL (conventionally calculated) of 87 mg/dl, HDL of 48 mg/dl. She added fish oil, 6000 mg per day. Three months later her LDL was 118 mg/dl, HDL 54 mg/dl. In other words, LDL increased by 31 mg. What gives? Several studies have, indeed, shown that fish oil raises LDL cholesterol, usually by 5-10 mg/dl. Occasionally, it may be as much as 20-30. Unfortunately, many physicians often assume that it's the (minor) cholesterol content of fish oil capsules, or some vague, undesirable effect of fish oil. It's nothing of the kind. Since we based Katie's program on (NMR) lipoprotein analysis, not conventional lipids (HDL, calculated LDL, triglycerides, total cholesterol), I knew that Katie also had a severe excess of intermediate-density lipoprotein, or IDL, and very-low density lipoproteins, VLDL. This signifies that after a meal, dietary fats persist for 12, 24,or more hours. Fish oil is a very effective method to clear IDL and VLDL, though sometimes it also causes a shift of some IDL and VLDL into the LDL class. Thus, the apparent increase in LDL. Another contributor: Conventional LDL is a calculated value, not measured. The calculation for LDL is thrown off by any reduction in HDL or rise in triglycerides. In Katie's case, the rise in HDL from 48 to 54 means that calculated LDL is becoming more accurate and rising towards the true measured value. At the start, Katie's true measured LDL was 122 mg/dl, 35 mg higher than the calculated value. Calculated LDL is therefore approximating measured LDL more accurately as HDL rises. The most important lesson to learn is that, if LDL rises significantly on fish oil and you haven't had lipoproteins formally measured, there may have been a substantial postprandial abnormality like IDL that was unrecognized. Heart disease is everywhere 16. janvier 2007 William Davis (0) If you ever need convincing that heart disease is everywhere, you should do what I do: subscribe to Google Alerts and have them forward news anytime the search phrase "heart attack" crosses the web. (Just go to Google, click on "more" to the right of the search bar, and follow the links.)Some recent samples:Workmates resuscitate driver after heart attack A woman coal mine truck driver had a heart attack and required resuscitation with a defibrillator 3 times on the way to the hospital. Heart attack kills groom at receptionA 34-year old man died during his wedding reception, leaving behind his 26-year old new wife.Heart attack ruled as cause of crash An Alabama man drove his pick-up truck into oncoming traffic while suffering a heart attack. Heart-attack victim to return to Hamburg stage Country music artist, Michael Harding, suffered a heart attack and cardiac arrest during a performance. He is apparently recovered and returning to the stage. That's just a sample from the last two days. While you and I are carry on a conversation on reversal of heart disease, our neighbors and friends drop over every day. Even though I witness successful heart disease reversal routinely, the rest of the world is not participating. Pass it on: Coronary disease is identifiable, preventable, controllable, and reversible. << Articles précédents Articles suivants >> Articles suivants12...9596979899100101102103...123124Articles précédents
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. With freedom comes responsibility. Otherwise, you might be looking for love . . .oops, I mean health . . . in all the wrong places.
Track Your Plaque APB 9. 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 Toggle navigation Home Blog Home Archive Join Now Se connecter Do stents prevent reversal? 27. janvier 2007 William Davis (3) I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents. Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent? These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all. At what score should I have a heart cath? 25. janvier 2007 William Davis (0) This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization? In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow. But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly. Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit. Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved. In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms. Niacin makes NY Times 24. janvier 2007 William Davis (0) In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again. (Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)Among their comments:...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.It is niacin, the ordinary B vitamin.In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets. Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver." Wheat: the nicotine of food 24. janvier 2007 William Davis (1) Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes. What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie? Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away. But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc. Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite. Good time for a heart attack? 22. janvier 2007 William Davis (0) Man Has Heart Attack At Right Place, Right Time If Robert Ricard had picked the wrong restaurant for lunch, he might have died.The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.Luckily, a disaster medical team was sitting nearby.A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another. What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path. Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place. How good is the South Beach Diet? 21. janvier 2007 William Davis (2) I'm a fan of the South Beach Diet. Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine. Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains. Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu. (From The South Beach Diet, Dr. Arthur Agatston) There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster. But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins. The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables. What really makes South Beach special, however, are its clever recipes. Dr. Arthur Agatston (the author) involved chefs from the restaurants in the South Beach area of Miami to help create healthy yet delicious recipes. We've tried many of them and, while they are different from traditional fare, are delicious and satisfying for the most part.Criticisms? None, really. But, when my patients choose South Beach (which I often encourage), I often have to impress on them that the Track Your Plaque program is not about weight loss. It is about seizing control of a potentially life-threatening disease. It is a far more important goal with greater implications. Weight loss is just one aspect of a coronary plaque control effort. For this reason, we sometimes have to make changes in the South Beach program to allow for correction of specific lipoprotein patterns. The most common modification is in people with small LDL particles. This pattern often does indeed respond to weight loss and/or niacin. However, it occasionally persists despite these efforts. We then will ask the patient to continue to restrict the re-introduction of wheat products, though it is allowed after Phase I in South Beach. In other words, for this specific and sometimes difficult to control lipoprotein pattern, a spedific modification of the off-the-shelf South Beach program is sometimes necessary. Of course, the diet is created to suit everybody. Lipoprotein analysis permits detailed insight into your patterns and it's only to be expected that specific modifications might be needed. But, as written, you can do quite well in your plaque control program by sticking to South Beach. Be patient with niacin 19. janvier 2007 William Davis (0) Mel's HDL started at 37 mg/dl one year ago. Mel had several other abnormal lipoprotein patterns along with his HDL (inc. small LDL and Lp(a)), but HDL was clearly a crucial factor in his panel. With a heart scan score of 1166, we needed to raise Mel's HDL to the Track Your Plaque target of 60 mg/dl. So Mel started niacin, our number one method to raise HDL, in addition to reducing his exposure to wheat products and other high glycemic index foods; increasing his physical activity; trying to reduce his excess tummy fat; fish oil; dark chocolate (2 oz per day) and red wine (1-2 glasses per day, preferably dark French reds). The form of niacin we often choose is SloNiacin (Upsher Smith), available over-the-counter for about $12-14 per 100 tablets.Mel started out with niacin 500 mg per day at dinner, increased to 1000 mg at dinner after four weeks. Although this is usually too soon to reassess HDL, Mel insisted. His HDL 41 mg/dl. Mel's disappointment was palpable. He was the usual type A personality: he wanted his HDL higher--now! So Mel insisted that we increase niacin to 1500 mg per day. (We never go higher than this if low HDL or small LDL is the indication for niacin; only when Lp(a) is present do we go higher.)Six months into this process, HDL: 45 mg/dl. Still a sluggish response. One year later, HDL: 68 mg/dl. Finally!That is typical for niacin, as well as combination of lifestyle changes Mel made. None of them result in an immediate rise in HDL; all take months to 1-2 years to exert full HDL-raising effect. Think of HDL as the 82-year old grandma who takes a long time to cross the street-she does get there!Note: Doses of niacin >500 mg per day should be taken with medical supervision. Can vitamin D be a SOLE risk factor? 18. janvier 2007 William Davis (6) Here's a crazy question. It occurred to me as I was talking to Drew, a slender, active 54-year old dentist with no bad habits including no smoking. Drew's heart scan score was 222. His lipoprotein analysis mostly revealed a lot of nothing, which is unusual. The only pattern that showed up was a modestly high LDL of 122 mg/dl with a very slight excess of small LDL. That's it. I would not be satisfied that these were sufficient cause for Drew's level of coronary plaque. Drew's 25-OH-vitamin D3 level: 15 ng/ml--severe deficiency--despite the fact that his doctor had suggested that he take a vitamin D2 preparation. In other words, Drew had been profoundly deficient, probably for years.Given the unimpressive cholesterol and lipoprotein values, could vitamin D serve as a trigger for coronary plaque all by itself? I don't have an answer and know of nobody else who does. However, my opinion is that vitamin D is indeed a potent risk that can cause heart disease as a sole risk factor. Perhaps it's another piece of circumstantial evidence suggesting that vitamin D has an enormous influence on health, including coronary plaque. Interestingly, the only other health problem Drew has had is prostate cancer, treated a few years ago with prostate removal and radiation. Good evidence suggests that vitamin D deficiency escalates risk of prostate cancer substantially. By the way, I've seen people taking vitamin D2 preparations, called "ergocalciferol," who are every bit as deficient as those who take no vitamin D at all. Avoid D2 or ergocalciferol preparations: they're worthless. Does fish oil raise LDL cholesterol? 17. janvier 2007 William Davis (1) Katie had an LDL (conventionally calculated) of 87 mg/dl, HDL of 48 mg/dl. She added fish oil, 6000 mg per day. Three months later her LDL was 118 mg/dl, HDL 54 mg/dl. In other words, LDL increased by 31 mg. What gives? Several studies have, indeed, shown that fish oil raises LDL cholesterol, usually by 5-10 mg/dl. Occasionally, it may be as much as 20-30. Unfortunately, many physicians often assume that it's the (minor) cholesterol content of fish oil capsules, or some vague, undesirable effect of fish oil. It's nothing of the kind. Since we based Katie's program on (NMR) lipoprotein analysis, not conventional lipids (HDL, calculated LDL, triglycerides, total cholesterol), I knew that Katie also had a severe excess of intermediate-density lipoprotein, or IDL, and very-low density lipoproteins, VLDL. This signifies that after a meal, dietary fats persist for 12, 24,or more hours. Fish oil is a very effective method to clear IDL and VLDL, though sometimes it also causes a shift of some IDL and VLDL into the LDL class. Thus, the apparent increase in LDL. Another contributor: Conventional LDL is a calculated value, not measured. The calculation for LDL is thrown off by any reduction in HDL or rise in triglycerides. In Katie's case, the rise in HDL from 48 to 54 means that calculated LDL is becoming more accurate and rising towards the true measured value. At the start, Katie's true measured LDL was 122 mg/dl, 35 mg higher than the calculated value. Calculated LDL is therefore approximating measured LDL more accurately as HDL rises. The most important lesson to learn is that, if LDL rises significantly on fish oil and you haven't had lipoproteins formally measured, there may have been a substantial postprandial abnormality like IDL that was unrecognized. Heart disease is everywhere 16. janvier 2007 William Davis (0) If you ever need convincing that heart disease is everywhere, you should do what I do: subscribe to Google Alerts and have them forward news anytime the search phrase "heart attack" crosses the web. (Just go to Google, click on "more" to the right of the search bar, and follow the links.)Some recent samples:Workmates resuscitate driver after heart attack A woman coal mine truck driver had a heart attack and required resuscitation with a defibrillator 3 times on the way to the hospital. Heart attack kills groom at receptionA 34-year old man died during his wedding reception, leaving behind his 26-year old new wife.Heart attack ruled as cause of crash An Alabama man drove his pick-up truck into oncoming traffic while suffering a heart attack. Heart-attack victim to return to Hamburg stage Country music artist, Michael Harding, suffered a heart attack and cardiac arrest during a performance. He is apparently recovered and returning to the stage. That's just a sample from the last two days. While you and I are carry on a conversation on reversal of heart disease, our neighbors and friends drop over every day. Even though I witness successful heart disease reversal routinely, the rest of the world is not participating. Pass it on: Coronary disease is identifiable, preventable, controllable, and reversible. << Articles précédents Articles suivants >> Articles suivants12...9596979899100101102103...123124Articles précédents
Do stents prevent reversal? 27. janvier 2007 William Davis (3) I've seen this phenomenon several times now: A highly-motivated Track Your Plaque participant with a stent in one artery will do all the right things--lose weight, achieve 60:60:60 in basic lipids, identify and correct hidden lipoprotein disorders, take fish oil, correct vitamin D, etc.Follow-up heart scan shows dramatic reduction in scoring in the two arteries without stents--30% per artery. But the artery with the stent will show marked increase in scoring above and/or below the stent. (It's impossible to tell what happens in or around the stent itself from a calcium scoring standpoint, since steel looks just like calcium on a CT heart scan.) In other words, there is marked plaque growth in the vicinity of the stent, despite the fact that dramatic reversal of atherosclerosis has occurred in other arteries without stents. Should we take this to mean that a stent destroys the opportunity for atherosclerotic plaque reversal in the stented artery? I don't know, but I fear this may be true. What dangers does this different sort of plaque pose? Is it the result of the injury imposed at time of stent implantation, some modification of flow or biologic responses as a result of the presence of the stent? These are all unanswered questions. But I believe that it is yet another suggestive piece of evidence that the best stent is no stent at all.
At what score should I have a heart cath? 25. janvier 2007 William Davis (0) This question comes up frequently: At what specific heart scan score should a heart catheterization be performed? In other words, is there a specific cut-off that automatically triggers a need for catheterization? In my view, there is no such score. We can't say, for instance, that everybody with a score above 1000 should have a catheterization. It is true that the higher your score, the greater the likelihood of a plaque blocking flow. A score of 1000 carries an approximately 25-30% likelihood of reduced blood flow sufficient to consider a stent or bypass. This can nearly always be settled with a stress test. Recall that, despite their pitfalls for uncovering hidden heart disease in the first place, stress tests are useful as gauges of coronary blood flow. But even a score of 1000 carries a 70-75% likelihood that a procedure will not be necesary. This is too high to justify doing heart catheterizations willy-nilly. Unfortunately, some my colleagues will say that any heart scan score justifies a heart cath. I believe this is absolutely, unquestionably, and inexcusably wrong. More often than not, this attitude is borne out of ignorance, laziness, or a desire for profit. Does every lump or bump justify surgery, radiation, and chemotherapy on the chance it could represent cancer? Of course not. There is indeed a time and place for these things, but judgment is involved. In my view, no heart scan score should autmatically prompt a major heart procedure like heart catheterization in a person without symptoms.
Niacin makes NY Times 24. janvier 2007 William Davis (0) In the wake of the crash and burn of Pfizer's torcetrapib, media attention has turned up the miracles of . . .good old niacin. The NY Times carried a well-written report on niacin in its recent report, An Old Cholesterol Remedy Is New Again. (Read the entire report at http://www.nytimes.com/2007/01/23/health/23consume.html?em&ex=1169701200&en=670fa84ae2ea648c&ei=5087%0A)Among their comments:...torcetrapib worked primarily by increasing HDL, or good cholesterol. Among other functions, HDL carries dangerous forms of cholesterol from artery walls to the liver for excretion. The process, called reverse cholesterol transport, is thought to be crucial to preventing clogged arteries.Many scientists still believe that a statin combined with a drug that raises HDL would mark a significant advance in the treatment of heart disease. But for patients now at high risk of heart attack or stroke, the news is better than it sounds. An effective HDL booster already exists.It is niacin, the ordinary B vitamin.In its therapeutic form, nicotinic acid, niacin can increase HDL as much as 35 percent when taken in high doses, usually about 2,000 milligrams per day. It also lowers LDL, though not as sharply as statins do, and it has been shown to reduce serum levels of artery-clogging triglycerides as much as 50 percent. Its principal side effect is an irritating flush caused by the vitamin’s dilation of blood vessels.Despite its effectiveness, niacin has been the ugly duckling of heart medications, an old remedy that few scientists cared to examine. But that seems likely to change.“There’s a great unfilled need for something that raises HDL,” said Dr. Steven E. Nissen, a cardiologist at the Cleveland Clinic and president of the American College of Cardiology. “Right now, in the wake of the failure of torcetrapib, niacin is really it. Nothing else available is that effective.”In 1975, long before statins, a landmark study of 8,341 men who had suffered heart attacks found that niacin was the only treatment among five tested that prevented second heart attacks. Compared with men on placebos, those on niacin had a 26 percent reduction in heart attacks and a 27 percent reduction in strokes. Fifteen years later, the mortality rate among the men on niacin was 11 percent lower than among those who had received placebos.'Here you have a drug that was about as effective as the early statins, and it just never caught on,' said Dr. B. Greg Brown, professor of medicine at the University of Washington in Seattle. 'It’s a mystery to me. But if you’re a drug company, I guess you can’t make money on a vitamin.'Of course, you and I don't have to wait for the media to endorse something. I'm nonetheless thrilled that this hugely helpful vitamin is gaining greater recognition. My preferred form nowadays is over-the-counter SloNiacin (Upsher Smith). Weve seen no liver side-effects and a minimal quantity of flushing. It's also reasonably priced, $13.99 for 100 tablets of 500 mg at Walgreen's. That's a lot cheaper than prescription Niaspan at $130 for 60 tablets. Perhaps the notoriety will cut back on the silly responses from some physicians that I still hear about from patients: "My doctor said to stop the niacin because it's going to destroy my liver."
Wheat: the nicotine of food 24. janvier 2007 William Davis (1) Yes, we know that wheat contributes to creating small LDL, drops HDL, raises triglycerides, and VLDL. We also know it indirectly slows the clearance of after-eating fats from the blood (curious, I know). Wheat products also increase inflammation (C-reactive protein), raise blood sugar, and contribute tremendously to diabetes. What many people don't know is that wheat products also have an addictive quality: have one donut and you want another. It's true for bread, breakfast cereals, pretzels, cookies, etc. How many times have you had just one Oreo cookie? Curiously, elimination of wheat products, unlike elimination of nicotine, usually causes the cravings to disappear. In other words, if you stop smoking cigarettes, the desire to smoke doesn't go away. With wheat products, the often overwhelming desire for more wheat products often just goes away. But most people are simply unable to dramatically reduce or eliminate wheat products from their daily diet and therefore struggle each and every day with excessive cravings for bagels, donuts, cookies, breads, etc. Try this useful experiment: Eliminate wheat products for a month and see what happens. Most people drop blood pressure, lose the tummy excess, feel more alert, see a drop in blood sugar, experience improvements in lipoproteins, and regain control over appetite.
Good time for a heart attack? 22. janvier 2007 William Davis (0) Man Has Heart Attack At Right Place, Right Time If Robert Ricard had picked the wrong restaurant for lunch, he might have died.The 71-year-old Michigan man suffered a heart attack shortly after ordering a glass of wine with friends at Bentley's Roadhouse on Saturday.Luckily, a disaster medical team was sitting nearby.A TV station in Michigan reported the above story. You've heard these "if it wasn't for ___, so and so would have died" stories. They're reported in all cities at one time or another. What amazes me about these common local stories is that they're accepted at all. The question that comes to my mind is "Why couldn't the heart attack have been averted in the first place?" Early identification then, as close as humanly possible, elimination of risk would have been a preferable path. Of course, it may not be the role of the media to cast judgement on why and how the entire episode could have been completely prevented from occurring. But you shouldn't fall into the same trap of complacency. We cannot expect others to save us when the "big one" hits. Your best assurance is to never have one in the first place.
How good is the South Beach Diet? 21. janvier 2007 William Davis (2) I'm a fan of the South Beach Diet. Though it is billed as a program for weight loss (for which it is very effective), it is really a program for health. The basic approach of South Beach involves:Eat good fats — Choose good fats from olive oil, canola oil, peanut oil, flaxseed oil, walnut oil, avocados, nuts, and fish. Omega-3 (fish oil) supplements are also fine. Eat good carbs — Good carbs include high-fiber, nutrient-dense fruits, vegetables, legumes, and whole grains. Eat lean protein — Good sources include eggs, low-fat dairy, nuts, seeds, legumes, skinless white-meat poultry, fish, shellfish, lean cuts of meat, and vegetarian options such as tofu. (From The South Beach Diet, Dr. Arthur Agatston) There's no doubt that South Beach can yield dramatic weight loss. In my experience, the success in weight loss depends on 1) how unhealthy your diet was in the first place, and 2) how long you can stick to Phase I, the inital phase during which weight loss is most dramatic. Some people have to periodically cycle back to Phase I to break a "plateau" or to lose faster. But South Beach is also healthy. It has all the ingredients of a healthy eating program: Low saturated and hydrogenated fats, rich in monounsaturated fats, high fiber, low- to moderate- glycemic index, vegetables and fruits, lean proteins. The Atkins' diet, in contrast, while very effective for weiglht loss, is an unhealthy process. I've seen lots of bladder infections, constipation, skin rashes, and kidney stones. That's just in the short term. If you stick to the "induction phase" (the no carbohydrate, low fiber, indiscriminate fat initial phase) for an extended period, I suspect that other adverse internal phenemena also develop that might not show for years, like cancer. But--it does work for weight loss!South Beach's Phase I is also carbohydrate restricted, but steers you towards healthier foods, such as healthy oils from olive and canola, raw or dry roasted nuts, and lean proteins and vegetables.

Does fish oil raise LDL cholesterol? 17. janvier 2007 William Davis (1) Katie had an LDL (conventionally calculated) of 87 mg/dl, HDL of 48 mg/dl. She added fish oil, 6000 mg per day.
