NY Times Jane Brody misses the mark 9. October 2007 William Davis (6) NY Times' health columnist, Jane Brody, recently wrote a bit of fluff for her paper: "CT Scans of the Heart Come With Trade-Offs In her report, she says:Coronary CT scans are being sold directly to the public, and they have found a market in health-conscious people who can afford them. But screening exams can have downsides. They can cause needless worry, and they sometimes reveal other potential conditions that require invasive procedures like biopsies to diagnose.I soon learned that among the strongest proponents of CT scans of coronary arteries were physicians with financial ties to drug companies that make statins and others connected to imaging centers that would profit directly from widespread CT screenings.She then goes on to discuss how the Framingham scoring calculation can tell you whether or not you are at low-, intermediate-, or high-risk for heart disease. She therefore concludes that heart scans are therefore irrelevant for the majority of people. She then proceeds to take a statin agent. This sort of nonsense continues to get published, despite the clear lack of real "digging" for the truth. She clearly fell for the conventional arguments that continue to mis-guide the majority of people, myths like: --the Framingham scoring system is reliable--Reliable it is NOT; it is susceptible to substantial "misclassification" bias, meaning people who appear low risk can actually be high risk, and people at high risk can actually be low risk. Among the latest studies that question the scoring system is Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). This study pointed out how the Framingham scoring system, which leaves out family history, can cause people classified as low risk to actually have substantial heart scan scores. This is crucial. A heart scan gets beyond the uncertainties and shows with >95% certainty whether or not hidden coronary atherosclerotic plaque is present.--"Coronary risk" is a dynammic phenomenon, subject to changes in a person's life. What if, for instance, a person smoked for 20 years, quit 10 years ago, lost 30 lbs, dropped their blood pressure as a result of the weight loss, then relied on the Framingham Risk Calculator to determine risk. They would likely be classified as low- risk, since risk factors now appear favorable. This person could easily have a heart scan score of 500, or 700, or 1000, levels that carry a cardiovascular event risk of 5-25% per year, hardly low-risk, because much of their risk accumulated earlier in life and is no longer revealed by an assessment of risk factors. --There are sources of risk that have nothing to do with Framingham, such as lipoprotein(a), which is often revealed by family history; the presence of small LDL, which co-varies with HDL and triglycerides, but can behave independently also; and, my favorite, deficiency of vitamin D. This would explain part of the 60-70% of people who are typically mis-classified by Framingham. Where did Ms. Brody get the idea that proponents of heart scans had ties to drug companies? I think she's barking up the wrong tree on that one. Of course, she ends up on a statin drug. For my part, I am a critic of statin drugs. Yes, they play a role, but they are miserably misused and abused by practicing physicians, based on the endless onslaught of drug company-sponsored trials that have served to distort their usefulness. If I were Ms. Brody, I would be quaking in my shoes, not knowing what my true risk for heart disease was, relying on the--at best--30% reduction in heart attack risk of Lipitor or other statin drug. Ms. Brody: You are not cured, you're simply wearing a superficial Band-Aid. If you want to know your true risk for heart attack, and you want a precise value that you can track over time, the answer is simple: Reject the conventional notion and get a heart scan.
"There must be a mistake" 9. October 2007 William Davis (2) Neal is our current male record holder for greatest reduction in heart scan score. (Yes, the ladies have the lead!) You may remember that this 40-year old man reduced his heart scan score from 339 to 161--a 51% drop. If you haven't yet read his story, go to http://www.cureality.com/library/fl_07-001nealt51.aspNeal reminded me of the experience he had when he underwent his second heart scan. Both scans had been performed at the same scanning center. At this center, the radiologists provide the added service of sitting down with people and actually going over the images and results. After the scan, the radiologist pulled up the result from Neal's first scan for comparison. "There must be a mistake! This score is lower. Scores never drop." The radiologist was apparently stumped, unable to provide an explanation. However, Neal then proceeded to tell the radiologist that we had warned Neal that this could happen and that he might even be told that it was due to error of some sort. This yielded a puzzled look on the radiologist but no further comment. Of course it's not a mistake. It's something we achieve on purpose. Curiously, I still get comments that this is impossible, heart scan scores never drop, etc. Of course, those of you following this conversation know this is completely untrue. Heart scan scores DO drop, and sometimes drop enormous amounts, as it did for Neal. I would have liked the radiologist to have had the lightbulb of understanding go off in his head when he realized that a reduction in heart scan score is a cause for celebration. Unfortunately, this radiologist's reaction is all too common: disbelief, confusion, dismissal. Heart disease reversal is simply not in the realm of understanding of most doctors, radiologists and cardiologists alike. By conventional thought, if you have it, it just gets worse. "Maybe some high-dose Lipitor might help." Ironically, when they see it right in front of their eyes, plain as day on the computer screen, they don't understand what has happened. It's Greek to them. Should this happen to you, don't be surprised. Just bite your tongue, because you know better.
Jimmy Moore Interview: Is saturated fat the villain we thought? 7. October 2007 William Davis (45) Enter "weight loss" or "low carb" in your web search and you can't help but stumble across the prolific and widely-connected Jimmy Moore. On his Blog, Livin' la Vida Lo Carb , Jimmy conducts a wide-ranging and informative discussion of the benefits of a low carbohydrate diet, a la Atkins. Though his initial claim to fame was the 180 lbs he lost in his first year of dieting on this approach, Jimmy has extended the conversation and built a considerable community of like-minded individuals, all of whom are participating in this grand "experiment." Anybody who looks at lipoproteins and associated factors in health will quickly come to the conclusion that processed carbohydrates are the culprits in much of heart disease, diabetes, and heart disease. But I have had a hard time dismissing the ill-effects of saturated fat. After all, we've all been taught--drilled--with the idea that saturated fats cause LDL cholesterol to go higher, cause arterial constriction, growth of atherosclerotic plaque, inflammation, even cancer. But there does indeed seem to be a growing sentinment that this long-held dogma may not be true. So I went to the ever-entertaining and informative Jimmy Moore, an able spokesman for these concepts. TYP: It's certainly impossible to argue with the success you had in weight loss and the health you've regained on your program. I think that the approach we use in diet in the Track Your Plaque program and the nutrition approach you advocate overlap to a great extent. We both emphasize plenty of vegetables, fruits, healthy oils, nuts, etc. The major point of difference seems to lie in saturated fat: We say restrict it, you say don't restrict it. Could you elaborate?JM: Thank you for inviting me to your blog today, Dr. Davis. I have nothing but deep respect and admiration for the work you are doing to help educate others about how to keep their heart health in tip-top shape. Keep fighting the good fight, my friend.While we do agree on probably 99% of the basic tenets of what I describe as "livin' la vida low-carb," the issue of saturated fat to me is one where we indeed do not. It's not a deal breaker regarding my support for what you do just as I'm sure you would say the same regarding your backing of what I do. If we all agreed on everything, then what a boring world this would be!My thinking on saturated fat has evolved since I started eating this way nearly four years ago. Like most people, I was terrified to eat ANY fat at all because of the abject fear that people like Dr. Dean Ornish and other so-called health "experts" instilled in me about how dangerously unhealthy it is to consume it. This fat phobia is arguably the single biggest contributor to the ongoing obesity crisis our world faces today.With that said, you and I both know fat consumption is a part of a healthy lifestyle. There are just too many benefits to the body that come from the consumption of fats and even saturated fats such as coconut oil, butter, lard, nuts, seeds, and animal fat when it is combined with a restricted carbohydrate intake.An intriguing study was presented at a scientific conference in November 2006 by two highly-respected researchers--Dr. Stephen Phinney from the University of California at Davis and Dr. Jeff Volek from the University of Connecticut--who conducted a side-by-side comparison of the amount of saturated fat in the blood of people on a low-carb diet with those following those highly-touted low-fat diets. What they found was the low-carb study participants had "significantly less" saturated fat in their blood than the low-fatties did.Here are the actual numbers from the study:- LOW-FAT/HIGH-CARB DIETERS: lowered saturated fat by 24%- LOW-CARB/HIGH-FAT DIETERS: lowered saturated fat by 57%- Eating 3X the saturated fat cut the amount in the blood in halfIn an interview I conducted at my blog with Dr. Volek last year (here's the link: http://livinlavidalocarb.blogspot.com/2006/09/volek-high-carb-low-fat-diet-useless-to.html), he said the conventional wisdom regarding fat, especially saturate fat, is dead wrong while the significance of carbs is all but ignored by those who claim to understand the metabolic response mechanism.Here's what Dr. Volek said in my interview: "Eating fat does not make you fat, storing fat makes you fat. And carbohydrates play a major role in storing fat. So the level of dietary carbohydrate is really the most important factor to control because it dictates what happens to fat. Carbs are dominant and fat is passive. When carbohydrates are low, fat tends to be burned, and when carbohydrates are high dietary fat tends to be stored. The same holds true for the atherogenic effects of saturated fat. The body handles saturated fat better when carbohydrates are low."Long-time low-carb practitioner and current President of the American Society of Bariatric Physicians (ASBP) Dr. Mary C. Vernon from Lawrence, Kansas confirms the findings of Dr. Volek and Dr. Phinney in a succinct recap of what their research showed.Here's what she said:"Eating fat (whatever kind) does not make you fat. It does not increase blood stream saturated fat. Eating carbs does make you fat. Eating carbs does put saturated fat in your blood stream."To me, as a simple layperson with no medical background, it's all a matter of who you believe. Do we continue to buy into the low-fat propaganda machine and assume that what they are telling us about saturated fat is true? Or do we instead start paying closer attention to the latest research that is coming out about saturated fat that doesn't exactly line up with the edicts of the last three decades? The choice for me is a simple one.And if you haven't read the brand new Gary Taubes book entitled GOOD CALORIES, BAD CALORIES yet, then it is REQUIRED reading to arm yourself with the research studies about fat. After you read that book, it will be almost impossible for ANYONE to believe fat, including saturated fat, is unhealthy.TYP: In our program, we advocate a wheat-free approach for many people, because of the addictive potential of wheat products, as well as the flagrant creation of the small LDL pattern that wheat products create, thereby adding to atherosclerotic plaque growth. However, many people express a concern over a lack of fiber in their diets if they eliminate whole wheat bread, pasta, Fiber One, Raisin Bran cereal, etc. Have you encountered any phenomena of low-fiber on your approach? JM: What an excellent question and I even wrote a humorous blog post about the importance of fiber intake called "Allow Your Bowel To Shake, Rattle, And Roll" (http://livinlavidalocarb.blogspot.com/2006/06/allow-your-bowel-to-shake-rattle-and.html). Fiber consumption is another one of those issues that not everyone who advocates a controlled-carb approach agrees is necessary. I'm on the side that it IS a healthy part of your diet and should be consumed in high enough quantities to keep you regular...something many people think is impossible on a low-carb diet. Not true! I take a fiber supplement like FiberCon, eat plenty of high-fiber vegetables, drink lots of water, and even consume high-fiber, low-carb products that help me maintain high levels of fiber in my diet (see my favorite ones in this post: http://livinlavidalocarb.blogspot.com/2007/04/there-are-plenty-of-low-carb-fiber.html).As for consuming the highly-touted "healthy whole grain" cereals that you mentioned, what a travesty that would be for people trying to manage their weight and health. While the cereal manufacturers have had a heyday in their marketing efforts promoting their whole grain content, it's all just a big fat ruse on the public trying to convince them that these cereals are somehow healthy for their bodies. Sure, they're better than the sugary cereals, but all those grains are metabolized as sugar inside the body, so you might as well be eating Lucky Charms and Fruit Loops!Many of these "healthy" cereals contain as many carbohydrates in a single bowl without the milk as I would eat in an entire day. Raisin Bran, for example, which used to be my favorite cereal before my low-carb lifestye, has a whopping 47 grams of carbohydrates. Needless to say, I don't touch that with a ten-foot pole nowadays because I would surely gain weight and get back on the blood sugar rollercoaster ride that I was on prior to beginning the Atkins diet on January 1, 2004. Plus, all those carbs just make you hungrier sooner, so it's better just to eat some delicious eggs cooked in butter, a couple of slices of sausage, and tomato slices to start your day off right. You'll get enough fiber in your body the rest of your day.TYP: 180 lbs of weight loss in your first year is absolutely astounding. I take it that you've continued this trend and have lost more weight since your early success. What role did exercise play during your first year and subsequently? How are your food choices today different from that first year? JM: Yes, that weight loss was indeed one of the greatest accomplishments I have ever experienced in my life. It was a hard-fought battle that even included a 10-week period where I was stalled with no weight loss. But I knew my chosen diet was the right one for me because I felt better than I ever had on a diet, was never hungry because I ate every 2-3 hours, and could see myself doing this for the rest of my life. So far, so good!It has been close to four years since I began this journey and I am indeed continuing this pathway to better health. My low weight in 2004 was 230 pounds and I currently weigh 225 pounds. As long as I keep my carbs reduced, I am able to maintain my weight right where it is. I've had minor fluctuations in both directions where I got down to as low as 215 pounds at one point (but didn't feel good at that weight) and as high as 252 pounds (when I was allowing myself one too many high-carb foods here and there).There's a balance that people need to find for themselves and it's different for all of us. I am one of the unlucky people who has to keep his carbohydrate intake below 50g daily or I gain. It's just a fact of life that I've come to grips with and realize is a necessity in order to manage my weight for the rest of my life. But I wouldn't have it any other way!Exercise was indeed a part of my low-carb weight loss success in 2004 as I forced myself to do cardio every single day as a commitment to this journey. In hindsight, that was probably not the best thing for me to do since the body has a rather peculiar way of telling you it needs to wiggle and move spontaneously on its own rather than forcing the issue. But I consider the exercise I did to be such an integral part of my success that I dedicated an entire chapter of my book to the subject.Today, my daily cardio routine is out the window and I choose instead to engage in activities outside the gym that let me burn calories and have some fun in the process. I regularly play volleyball, basketball, and referee flag football at my church which all give me quite a workout. I'm very physically active and fit on my 6'3" body and just enjoy burning off all this excess energy that I have been given since losing nearly have my weight! I do want to get into a little more organized resistance training routine soon to try to shape and tone some areas of my body that still show signs of that 410-pound man I used to be (although the loose, hanging skin in my abdomen and inner thighs isn't going to get any better with exercise since the elasticity has been ruined from being stretched out so far). Here is a link to some posts and pictures I have written about this subject:http://lowcarblinks.blogspot.com/2007/04/theme-based-low-carb-links-loose-skin.htmlAs for my food choices today compared to my weight loss year in 2004, they haven't really changed a whole lot. This was a lifestyle change in every sense of the phrase and I've learned to implement this way of eating into a permanent and healthy diet that I can and will gladly live with forever and ever amen. I probably eat more berries, melons, and nuts today than I did then, but otherwise it's the identical diet. TYP: I'm sure that you are as impressed as I am that much of the wisdom in healthy eating doesn't always come from doctors or clinical studies, but from the collective wisdom that emerges from this national experiment (inadvertent, for the most part) in eating. Your Livin' La Vida Low-Carb is, in my view, a perfect example of the sort of wisdom that is helping all of us understand what happened to our health over the last 20 years. Does the approach you advocate today differ in any substantial way from the diet as originally articulated by Dr. Atkins? JM: Actually, my personal diet is precisely based on the teaching of the late great Dr. Robert C. Atkins in his classic bestseller DR. ATKINS' NEW DIET REVOLUTION (DANDR) book. But most people are surprised when they learn I do not necessarily advocate the Atkins diet as the nutritional approach for everyone. Nope, I sure don't!Instead, my philosophy is simple: Find the diet plan that will work for YOU, read and research everything you can about that chosen plan, follow that plan exactly as prescribed by the author of that book, and then KEEP doing that plan for the rest of your life. If you do that, then there's no reason why you can't succeed just like I did.Anyone interested in doing the low-carb lifestyle and needs help finding which plan is right for them, let me HIGHLY encourage you to pick up a copy of Dr. Jonny Bowden's LIVING THE LOW-CARB LIFE (read my review: http://livinlavidalocarb.blogspot.com/2005/05/must-have-book-for-everybody-doing-low.html). It's the perfect overview of low-carb living with a comparison and recap of the major plans.THANK YOU again for allowing me to share my story with you and your readers, Dr. Davis!

Mammogram of the heart 6. October 2007 William Davis (3) Some people have called CT heart scans the "mammogram of the heart." The analogy contains a lot of wisdom.First of all, both--mammograms and CT heart scans--are screening tests, one for cancer, of course, the other for coronary atherosclerotic plaque. Both are performed in specific age groups, mammograms in women 40 years and over (generally), heart scans in women 50 years and over (generally).Mammograms: Left, normal; right, a small mass. (Courtesy Nat'l Institutes of Health and Wikipedia.)Both are also meant to be repeated periodically when normal as a surveillance process.Both use low quantities of radiation of about 0.3-0.4 mSv (the most real-life measure of total body exposure), a modest quantity of radiation.Both are good for their purposes, though not perfect. Can a mammogram performed properly miss a small cancerous mass? Sure it can, but it's still unusual. Can a CT heart scan miss the non-calcified plaque prone to rupture? Sure it can, but this is also unlikely (<5% probability).Given the exorbitant costs of medical tests, both are quite inexpensive. On the flip side, they are both also quite unprofitable for the centers providing the tests. Unfortunately, this means that mammography centers and heart scan centers come and go because of the difficulties of the profit-side of these services.Both tests initially struggled to gain acceptance among the medical community. In 1960, for instance, mammograms were performed on standard x-ray devices, the same as that used to perform chest x-rays--low precision, high radiation back then. In 1969, dedicated mammography devices made the scene. However, it took over 10 years for even these new dedicated devices to become widely used. Use of mammograms has gradually increased over the ensuing 20 years. In other words, 47 years have passed since the introduction of mammography. CT heart scans, of course, have had a shorter history of approximately 20 years, since engineer, Dr. Douglas Boyd, first invented the "ultra-fast" EBT devices, the first devices with sufficient scanning speed to scan the heart and coronary arteries. One interesting difference between the two: In a woman between the age of 50 and 60, the likelihood of detecting cancer is 1 in 237. The likelihood of detecting coronary atherosclerotic plaque? About 1 in 4. Coronary disease eventually kills 1 in 3 females, hugely overshadowing breast cancer in frequency. Progress on both fronts, one in cancer detection, the other in atherosclerotic coronary plaque detection. But still lots more progress to go.
Dr. Susie Rockway on conjugated linoleic acid (CLA) 5. October 2007 William Davis (7) I’m fascinated by the perspectives that nutritionists (free-thinking ones, at least), food scientists, and biochemists bring on nutrition and nutritional supplements. A few months ago, I met a fascinating nutritionist/biochemist named Susie Rockway, PhD. Dr. Rockway brings a world of experience in the world of nutritional supplements, clinical trials with supplements, and their development. She has special expertise in conjugated linoleic acid (CLA), having been among the scientists who initially developed CLA as a supplement. We are also exploring CLA as a possible addition to the Track Your Plaque program and wanted to get Dr. Rockway’s perspectives. So I asked Dr. Rockway if she’d answer a few questions for us. TYP: Dr. Rockway, we understand that you are particularly excited about the prospects of CLA for FAT loss and perhaps for regression of atherosclerosis. Can you tell us about the origins of your interest in CLA and why you're so enthusiastic? Dr. Rockway: I have been fascinated with this unique fatty acid since the early 1990’s when CLA was first being discussed as nature’s most potent anti-carcinogen. I was then working in the granting/funding section of the National Dairy Council and saw this molecule as truly one of the future functional fats that would likely benefit people (next to omega-3’s!) I think the benefits of CLA have just begun to be investigated—animal studies are extraordinary for showing fat reduction, lean mass (muscle) increases, immune enhancements, blood glucose normalization, anti-inflammatory properties and plaque reduction! Human data to date is very encouraging for fat reduction. As a nutritionist seeing the massive increase in abdominal fat (stomach fat) in the world population and the direct relationship to cardiovascular disease, I see CLA as a great supplement to take to help this. Of course eating lots of vegetables, fruit, lean protein and whole grain products is also a must for maximizing good health. I am studying the impact of CLA in reducing muscle loss in aging women—a condition known as sarcopenia. As we lose muscle with age, we lose strength, falls increase, we become frailer, and eventually many of us lose our independence. Along with the muscle atrophy, most people gain fat—never a good thing! So, if CLA can reduce fat and increase muscle, our bodies are more likely to withstand the hurdles that life throws at us much more efficiently. So, how can you not be excited about this very bioactive molecule? TYP: What are your specific areas of interest in nutrition and health? Dr. Rockway: I strive to understand the role of bioactive molecules that can be taken to improve the aging process and enhance health. As a trained nutritional biochemist, we tend to look at cell metabolism in a very ideal sense: what we learned in our biochemistry texts years ago where all substrates, proteins, enzymes, etc. are made exactly when we need them, where all cells behave as they should. Unfortunately, little research has been devoted to understanding the changes in metabolism as we age. Do we still produce everything as efficiently as when we were 20? I suspect not. So, I think we need a little help, and supplements are a key to getting there. Two nutrients that I think are emerging as “super nutrients” are the fatty acids found in fish oil (EPA and DHA) and vitamin D. Where we know these two nutrients are essential for life, we are seeing that they play a huge role in the QUALITY of life. Mood, depression, PMS, wound healing, bone growth, atherosclerosis, and arthritis are clinical areas where we see a direct benefit with doses of omega-3 and Vitamin D that are probably much greater than the RDA. Our current requirements for nutrients are really based on fixing deficiencies and not maximizing health, and maximizing health is where I’m at. Thus, I am very interested molecules like CLA as mentioned above, and other bioactive ingredients such as plant derived ingredients (phytochemicals) called flavonoids that may well help explain why people who have diets high in fruits and vegetables are less likely to have certain cancers and heart disease. Reducing oxidative stress through foods that provide these active molecules (think colored fruits and veggies) is a new and exciting area of research. TYP:The big "diet experiment" in America has clearly steered people in the wrong direction, usually by 50 or more pounds. As a scientist in nutrition, what are your thoughts? Dr. Rockway: The American Heart Association was keen 20 years ago to promote the low-fat diet for all Americans as the key way to reduce cholesterol levels and decrease chance of heart disease, the number one killer of men and women. However, I must admit the nutritional community bought into this one, too. Unfortunately, the general public took this message to reduce percent fat in their diet (and they did a bit), but increased overall calories instead—and a large portion of the increased calories was from simple carbohydrates. I’m convinced that this in itself has been part of the huge rise in obesity…we simply eat more food and it’s not the healthy kind of food either.When you increase sugar intake beyond what you burn off, you will store some of it as glycogen in the liver and muscles, but you will convert most of the excess into fat—and that we can store very efficiently! The fat that is made in the liver is sent to the blood as VLDL’s which are the precursor to the class of lipids called low density lipoproteins (LDL) that are the “lethal” type of cholesterol circulating in our blood. So, Americans now have to listen to a new message that they need to eat more fruits and vegetables in hopes they will cut down on fast foods—tending to be high in fat (saturated particularly), low in fiber and low in nutrients and other high calorie dense foods. We nutritionists have our work cut out for us, that’s for sure. TYP: We are especially excited that nutritionists are assuming a leading role in shining light on the confusion in diet and nutrition that has characterized the last 40 years. Do you have a sense for the emerging important issues for the next 10 years? Dr. Rockway: Certainly, the scientists in the nutritional field are well aware of the problems facing this nation—it’s in fixing them that we fall short! We aren’t very well coordinated to get a single message out, nor do we all agree on what that message should be. I feel that people need to eat healthy MOST OF THE TIME, exercise all of the time, and take supplements that have clear evidence of benefit. Lots of my colleagues would not concur with supplement use. Our bodies were designed to move a lot and eat a lot…we just do the latter now and are paying the price!One emerging and very exciting area that we have to teach Americans is that all fat is not bad. The different types of fat—omega-6 vs. omega-3, are where we need to focus our education. Decreasing the corn oil we pour on everything needs to go out the window! Consume olive oil and eat fish or take fish oil supplements—we simply have tons and tons of research showing the benefits of reducing the ratio of omega-6 to omega-3. Did you know that cattle that are grass fed actually have less omega-6 in their tissues and more CLA? But most cattle are fed corn-based diets, so we have perturbed their natural selection of food and their fat composition. See, it all comes back to CLA!TYP: Thanks, Susie!

Which is better? 4. October 2007 William Davis (12) If you have the common pattern of high LDL particle number (NMR) with small LDL--a pattern highly related to coronary plaque--which is better:Lipitor or a combination of fish oil, vitamin D, and elimination of wheat? Lipitor quite effectively reduces LDL particle number, usually on the order of 40% or so. Effect on LDL particle size: None. Side-effects: plenty, including muscle aches (inevitable in my experience, not the ridiculous 2% they claim) and occasionally mental effects such as impaired short-term memory.Lipitor does seem to exert a modest effect on reduction of C-reactive protein, around 30%. It also reduces cardiovascular events by 30%. A combination of fish oil, vitamin D, and elimination of wheat: Reduces LDL particle number commonly by a similar 40% (though variable, depending on body weight). There is substantial improvement in LDL particle size, a large drop in C-reactive protein, often >50%, a 30% or more reduction in cardiovacular events. On this combination, however, you also:--Lose weight, often substantially. --Improve bone health, esp. osteoporosis and arthritis. --Reduce cancer risk from the vit D supplementation. --Reduce risk of stroke. --Reduce postprandial (after-eating) abnormalities like intermediate-density lipoprotein.--Reduce winter blues. --Experience more energy. --Obtain increased clarity of thought (from elimination of wheat). --Reduce blood pressure. Oh, and there's no muscle aches.
Heart health for stupid people 4. October 2007 William Davis (3) I'm kidding.What I'm referring to is the incredibly lame information I come across that passes as "heart health" on the internet, magazines, and other media. Just to keep abreast of what is being said, I subscribe to multiple newsletters and magazines and I witness the sorts of advice offered to the reading public. A recent long-winded article on a popular website listed the "exciting" strategies available for a healthy heart:Eat healthy--by eating a "balanced" diet low in saturated fatDon't smokeExerciseDon't ignore chest pain symptoms or breathlessnessKnow your numbers! meaning your cholesterol numbers. "If your cholesterol is high, you may need to speak to your doctor about medication to reduce it."Surely they must all believe we're stupid. Otherwise, why would they repeat the same obvious information over and over again? Quit smoking? Gee, you think so?How about some real heart healthy advice:Get a heart scan--since we have to accept that cholesterol values are a miserable failure in detecting hidden heart disease. So is waiting for symptoms to appear.If you have any measure of coronary plaque, ask your doctor to assess lipoproteins, not lipids (cholesterol).Take fish oil for omega-3 fatty acids--At a dose of 1000 mg or more of EPA + DHA, heart attack risk is reduced by at least 28%.Eliminate wheat and other processed carbohydrates --Small LDL has emerged as the number one cause of coronary plaque, not high cholesterol from saturated fat.Get vitamin D assessed--The effects are huge--HUGE. There's already a study in a kidney disease population that showed a substantial reduction in mortality with vitamin D supplementation. More data are coming, including our own.That's a start--truly effective, practical heart healthy strategies that go way beyond the conventional bland advice. Copyright 2007 William Davis, MD
Money, money, money, money 3. October 2007 William Davis (3) I've been asked the question numerous times:Why aren't heart scans more popular? First, let me qualify by saying that heart scan have indeed grown in popularity over the past decade. I think the real question is: Given the enormous usefulness of CT heart scanning to detect hidden, asymptomatic coronary atherosclerotic plaque, why haven't they more readily been incorporated into conventional medical practice? That's easy: There's no money in it.Say, for instance, your doctor orders a heart scan and somehow receives a $1000 for the test. Scan centers would be scanning 100 people a day, falling over themselves to do scans. This would be similar to a heart catheterization. Order a catheterization, do 30 minutes of work, and get $1000. Or, order a nuclear stress test. Depending on how its done and where, $1800-4000 is paid by the insurer. Order a CT heart scan and how much is paid to the doctor? Usually nothing. At most, a nominal fee might be paid if the doctor reads the scan. With heart scans, there simply is no big payoff. We learned the implications of this situation 10 years ago when I was trying to help my friend, Steve Burlingame, the owner of Milwaukee Heart Scan. (I am NOT and NEVER WAS an owner.) Steve was trying to let everybody know about this great new $2 million dollar heart scan device in the Milwaukee area. The first few years were tough for Steve: Carrying the substantial expense of this device while doctors essentially gave the technology the cold shoulder. It simply did not fit into the financial equation. Why change the way things were, particularly when there was virtually no financial reason to do so? To counter this, Milwaukee Heart Scan followed the model many other scan centers have followed and marketed directly to the public.I see this as yet another example of why people need to take control of health care away from doctors and hospitals, the current controllers of the system who are providing a disservice to the public they are supposed to be serving. These institutions, for the most part, serve their self-serving financial interests, notWisconsin, the Women's International Pharmacy. They have filled hundreds of hormone prescription for us. They are responsible in their dispensing practices, in our experience. In fact, they have been at least as good, if not better, than other pharmacies we've dealt with. We believe in protecting our rights to prescribe and you to use the choice of hormone preparations you and your doctor desire. This should include bio-identical hormones. The transparent profit motive from Wyeth should raise the hairs on your neck. If you would like to post your comment to the FDA, there's a little time left. The folks at Womens' International Pharmacy have made it easy by posting links on their website. Go to http://www.womensinternational.com and just follow the instructions. Here's a sample of some of the objections citizens have raised to Wyeth's petition:I have been taking bioidentical hormones for two years. Bioidentical Hormones have been a great relief to me without the risk. I consult with my Physician who prescribes bio-identical hormones specifically for me, and my pharmacist prepares them. Without this medication and I would not be able to sleep; I would not be able to work due to the constant hot flashes. Without this medication, I find that I have less tolerance and I am considerably disagreeable. I also have problem with my memory without them. I want the bioidentcial hormones for the health benefits they provide. I urge you to not be swayed by Wyeth's petition. The product Premarin made by Wyeth, is made from pregnant horses not natural sources. Wyeth's hormones have been shown to cause cancer. I would not expect my government and its officials to submit to the highly funded petitioning of a pharmaceutical company who product is threatened by bioidentcial hormones. I do not expect my government to approved Wyeth's petition and leave me no choice of bioidentcial hormones and only the choice of Wyeth's cancer causing drugs Preamrin and Prempro. I ask that the FDA reject Wyeth's petition Docket #2005P-0411. Another petitioner writes: As a woman I take exception to Wyeth accusing the Compounding Pharmacy industry of unsafe practices. As a citizen of the United States I expect the FDA to stand up for my rights and the rights of all women who have found or in the future may seek consistent, safe and effective treatment with bioidentical hormones. Eliminating options by bowing to a large pharmaceutical company like Wyeth is not in the public interest and would deprive hundreds of thousands of American women from access to bioidentical hormones. Synthetic hormone replacement has been proven unequivocally unsafe in a government sponsored study and should not be forced as the sole treatment option for women. I hereby request the FDA rule against Wyeth's request. The FDA should not close down the bioidentical option of healthcare. I welcome studies of bioidentical hormones even though they are already FDA-approved and have been working effectively for decades. We already have the proof - hundreds of thousands of women, who over the past two decades have chosen bioidentical hormones based on their physicians' assessments. They are living proof that bioidentical hormones are safer and more effective and reliable than synthetic hormone drugs. A physician and user of bio-identical hormones writes:Wyeth, the filer of this complaint, is trying to prevent women from being able to choose less expensive compounded options for hormone replacement. There is medical evidence that in modifying the structure of their drugs (such as Premarin and Prempro) so that they could be patented, they may have introduced factors that cause the health risks identified in the Women's Health Initiative. This complaint appears to be filed for commercial purposes because of the market share that has shifted from Wyeth's products to bio-identical products from compounding pharmacies. If the complaint were upheld, patients and their doctors would not have a choice in hormone treatments. Wythe's commercial strategy of trying to eliminate the 'competition' from compounding pharmacies is against the public interest and in the interest of its own corporate profits. Women and their doctors should be able to choose between patented formulations such as those offered by Wyeth, bioidentical formulas available from compounding pharmacies, and no hormone treatment. I have been taking bio-identical hormones for several years and have had excellent results in improving my symptoms. I have been unable to take other synthetic hormones in the past, and am very concerned that my best treatment option will be taken away.
If you get a 64-slice CT coronary angiogram 3. July 2006 William Davis (0) With new 64-slice CT scanners popping up everywhere nowadays, be sure to get your heart scan with it. The new scanners do indeed provide wonderful images of the coronary arteries. But, say you have a 20% blockage in one artery by a coronary angiogram generated on one of these devices. What will you do in 1, 2, or 3 years when you want to know if you have progressed? Should you have the CT angiogram repeated?Well, if you did you'll be exposed to a large dose of radiation--appropriate for a diagnostic test, but not for a screening test. The radiation exposure is not that different from undergoing a full conventional cardiac catheterization, or up to 100 chest x-rays. "20% blockage" is also, contrary to popular opinion, not a quantitative measure. It is just an estimate of the diameter reduction at one spot. That number says nothing about the lengthwise extent of plaque. It also says nothing about the potential for "remodeling", the phenomenon of artery enlargement that occurs as plaque grows. In other words, if you had another CT coronary angiogram a year later and was told that your blockag was still 20%, in reality you could have had substantial plaque growth but it would not be reflected in that value. People will come to me after having a CT angiogram for an opinion. Unfortunately, I send them back to their scan center to get a simple coronary calcium score. That measure is easy, quantitative, precise, and can be repeated yearly if necessary to track progression. (Track Your Plaque--I hope most of you get this by now.) Some physicians poke fun at the heart scan, or calcium, score--it's old, boring, only a measure of hard plaque. None of that's true. The coronary calcium score is a measure of total plaque (hard and soft). And when you are empowered to learn how to control and reduce your score, then it's the most exciting number in your entire health program!Don't fall for the hype. If you go to a scan center and they insist on a 64-slice CT scanner, or if your doctor orders one, you should insist on getting a calcium score out of the test. Just ask. If they refuse, go somewhere else. Centers that refuse to generate a score have one thing on their mind: identifying people with severe blockages sufficient to obtain the downstream financial bonanza--angioplasty, stents, and bypass surgery.
If you have hypertension, think Lp(a) 2. July 2006 William Davis (0) Clair has coronary disease. Clair first came to attention at age 57 when she suffered a large heart attack involving the front of her heart (the "anterior wall") two years ago. Her cardiologist implanted a drug-coated stent. Her doctors advised her to "cut the fat" in her diet, exercise, and take Lipitor. One year later, she required a stent to another artery (circumflex). At this point, Clair was thoroughly demoralized and terrified for her future. Her first heart attack left her heart muscle with only 50% of normal strength. She came to my office for another opinion. Of course, one of the first things we did was to identify all causes of her heart disease. No surprise, Clair had 7 new causes not previously identified, including low HDL (37 mg/dl), a severe small LDL particle pattern (75% of all particles were small), and Lp(a). Her blood pressure was also 190/88, despite her relatively slender build and 3 medications that reduced blood pressure. That's a Lp(a) effect: Exagerrated coronary risk along with unexpected hypertension that often seems inappropriate. In fact, I saw several patients just this week with lipoprotein(a), Lp(a), and exagerrated high blood pressure (hypertension). It's not that uncommon.Though it has not been described in the medical literature, our experience is that hypertension is a prominent part of the entire Lp(a) "syndrome".Lp(a) is responsible for much-increased potential for coronary disease (coronary plaque). It increases in importance as estrogen recedes in a woman (pre-menopause and menopause) and testosterone in a man, since both hormones powerful suppress Lp(a) expression (though why and how nobody knows). I believe that Lp(a) is also responsible for hypertension that most commonly develops in a persons mid-50s and onwards, often with a vengeance. 3 or 4 anti-hypertensive medications and still not controlled. Role of l-arginineL-arginine may be more helpful in this situation than others. L-arginine, recall, is the supply for your body's nitric oxide, a powerful dilator of the body's arteries and thereby reduces blood pressure. We use 6000 mg twice a day, a large dose that requires use of powder preparations rather than capsules. More reading about l-arginine and nitric oxide is available through Nobel laureate, Dr. Louis Ignarro's book, NO More Heart Disease : How Nitric Oxide Can Prevent--Even Reverse--Heart Disease and Stroke, available at Amazon.com ( http://www.amazon.com/gp/product/0312335814/104-1247258-6443909?v=glance&n=283155).Will l-arginine truly reverse heart disease on its own? No, I don't believe so. Contrary to Dr. Ignarro's extravagant claims, I find l-arginine a facilitator of plaque regression, i.e, it helps other strategies achieve regression, but it does not achieve regression or reversal by itself. (Note that Dr. Ignarro is a lab researcher who studies rats and has never treated a human being.)But l-arginine may have special application in the person with lp(a), particularly if hypertension is part of the syndrome.Note: As always, please note that I talk frankly about l-arginine and other supplements and medications but have no hidden agenda: I am not selling anything, nor am I affiliated with any source/website/store etc. that sells these products. If I advocate something, I do so because I truly believe it, not because I'm trying to sell something. I make this point because so much nonsense is propagated in the media because of profit-motive. That's not true here.
Dr. Ornish: Get with the program! 30. June 2006 William Davis (2) In the era up until the 1980s, most Americans indulged in excessive quantities of saturated fats: fried chickem, spare ribs, French fries, gravy, bacon, Crisco, butter, etc. Along came people like Nathan Pritikin and Dr. Dean Ornish, both of whom were vocal advocates of a low-fat nutritional approach. In their programs, fat composed no more than 10% of calories. This represented a dramatic improvement--at the time. In 2006, a low-fat diet is a perversion of health. It means over-reliance on breads, breakfast cereals, pasta, crackers, cookies, pretzels, etc., the foods that pack supermarket shelves and that now constitute 70-80% of most Americans' diet. Dr. Ornish still carries great name recognition. As a result, his outdated concepts still gain media attention. The June, 2006 issue of Reader's Digest, in their RDHealth column, carried an interview with Dr. Ornish in which he reiterates his fat-phobia. However, on this occasion he takes a different tack. This time he rails against the "dangers" of fish oil and omega-3 fatty acids. "I've recently learned that omega-3s are a double-edged sword...In some cases, omega-3s could be fatal."He goes on to say that, while he believes that fish oil may prevent heart attacks, it has fatal effect if you already have heart disease. Does this make sense to you? He's basing his views on a single, obscure study published in 2003 conducted in rural England that showed an increase in death and heart attack on fish oil. Most authorities have not taken these findings seriously, since they are wildly contrary to all other observations and because the study had some design flaws. Despite the fact that this isolated study runs counter to all other, better-conducted studies seems not to matter to Dr. Ornish. Clinging to the low-fat concept is like hoping 8-track tapes will make a comeback. It's not going to happen. We enjoyed the benefits while they lasted, appropriate for the era. But now, they're woefully outdated.The overwhelming evidence is that fish oil provides tremendous benefits with little or no downside. In the Track Your Plaque program, fish oil remains a crucial supplement to gain control over your coronary plaque and stop or reduce your heart scan score. Ignore the doomsday preachings of Dr. Ornish. (Watch for an article I wrote updating the benefits of fish oil for Life Extension magazine.)
The cholesterol fallacy 29. June 2006 William Davis (0) Evan spotted the kiosk set up in the middle of the local mall. "Free cholesterol screenings. Know your heart health!" the sign declared.It was a free cholesterol screening being offered by a local hospital. The friendly nurse behind the kiosk had Evan fill out a form, then pricked his finger. Five minutes later, she reported to him with a smile, "Sir, your cholesterol is 177--your heart's fine! We get concerned when cholesterol is over 200. So you're in a safe range."What the nurse failed to recognize is that Evan's HDL was 30 mg, a low value that actually places him at high risk for heart disease. Low HDL also signifies high likelihood of the small LDL particle pattern, a marked predisposition towards pre-diabetes and diabetes, a probable over-reliance on processed carbohydrates in his diet, a dramatically increased probability of hidden inflammation (e.g., elevated C-reactive protein), increased tendency for high blood pressure. . .In other words, Evan's "favorable" total cholesterol is, in truth, nonsense. It's misleading, falsely reassuring, and provided none of the insight that a real effort might have yielded. Like hippies, tie-dye, other relics of the 1960s, total cholesterol needs to be put to rest. It has served many people poorly and been responsible for countless deaths. When you see a kiosk or other service like this, even if it's free, run the other way.
"Heart disease a growth business" 29. June 2006 William Davis (0) So announced a Boston newspaper recently, featuring a story about new heart program at a local hospital. They were announcing how a hospital had entered the cardiovasculare procedure game and how it would boost their bottom line. The article discussed how the hospital administration was anticipating "a surge in patients from the baby boom generation."To justify this new program, the article quoted an administrator from another hospital: "Cardiovascular issues is [sic] the number one cause people sought treatment at our hospital."The hospital featured in the story had spent $13.5 million dollars to develop their program. Do you think they'll make it back?You bet they will--many times over. Hospitals are businesses, complete with a bottom line, an expectation of profit and an eye towards growth. The hospitals in the city where I live (Milwaukee, Wisconsin) are, as in Boston and elsewhere, very aggressive--expanding into new territories, hiring new "salesmen" (physicians), all to capture more marketshare and produce more "product" (your coronary angioplasty, stent, bypass surgery, defibrillator, etc.). The equation for hospital profits is tried and true. Ignore your heart disese risk and you can help your local hospital grow its business. Neglect to get your heart scan and you can help your hospital pay down its debt. Get a heart scan, then do nothing about it, and you may even justify a pay raise for the hospital administrators for record revenue growth and profit.Hospitals are a growth business because of the failure of most people and their doctors to 1) identify hidden coronary disease (CT heart scan to obtain your heart scan score), then 2) seize control over it (the Track Your Plaque program or, at least, your doctor's guidance along with your efforts at prevention).Unless you do so, you are highly likely to help your hospital boost its annual goal for procedures.
The myth of small LDL 28. June 2006 William Davis (1) Annie's doctor was puzzled.Despite an HDL cholesterol of 76 mg (spectacular!) and LDL of 82 mg, her CT heart scan showed a score of 135. At age 51, this placed her in the 90th percentile. Not as bad, perhaps, as her Dad might have had, since he died at age 54 of a heart attack. So we submitted blood for lipoprotein testing. Surprise! over 90% of all her LDL particles were small. (By NMR, they're called "small". By gel electropheresis, or the Berkeley Lab test, or VAP (Atherotech) technique, they're called "HDL3".)What gives? Traditional teaching in the lipid world is that if HDL equals or exceeds 40 mg/dl, then small LDL will simply not be present. Well, as you can see from Annie's experience, this is plain wrong. Yes, there is a graded, population-based effect--the lower your HDL, the greater the likelihood of small LDL. But small LDL is remarkably persistent and prevalent--regardless of your HDL.We've seen small LDL even with HDLs in the 90's! I call small LDL the "cockroach" of lipids. If you think you have it, you probably do. Getting rid of small LDL requires a specific bug killer. (Track Your Plaque Members: Read Dr. Tara Dall's interview on small LDL.) Don't let anybody blow off your request for lipoprotein testing just because your HDL is high. That's just not acceptable. Loads can be wrong even with a favorable HDL.
My stress test was normal. I don't need a heart scan! 28. June 2006 William Davis (0) Katy had undergone a stress test while being seen in an emergency room, where she'd gone one weekend because of a dull pain on the right side of her chest. After her stress test proved normal, she was diagnosed (I believe correctly) with esophageal reflux, or regurgitation of stomach acid up the esophagus. She was prescrbed an acid-suppressing medication with complete relief. But Katy also had coronary plaque. Three years ago, her CT heart scan score was 157. She'd made efforts to correct the multiple causes, though she still struggled with keeping weight down to gain full control over her small LDL particle pattern. I felt it was time for a reassessment: another heart scan. After three years, without any preventive efforts, Katy's score would be expected to have reached 345! (That's 30% per year plaque growth.) It's a good idea to get feedback on just how much slowing you've accomplished. But Katy declared, "But I didn't think another heart scan was necessary. My stress test was normal!"What Katy was struggling to understand was that even at the time of her first scan, a stress test would have been normal. Plaque can be present with a normal stress test. Plaque can even show explosive growth all while stress tests remain normal. Just ask former President, Bill Clinton, how much he should have relied on stress tests. (Mr. Clinton underwent annual stress nuclear tests. All were normal and he had no symptoms--all the way up 'til the time he needed urgent bypass surgery!)Of course, at some point even a crude stress test will reveal abnormal results. But that's years into your disease and a lot closer to needing procedures and experiencing heart attack. So, yes, Katy would benefit from another heart scan despite her normal stress test. The message: Don't rely on stress tests to gauge whether or not plaque has grown, stabilized, or reversed. Stress tests can be used to gauge the safety of exercise, blood pressure response, and the potential for abnormal heart rhythms. Stress tests can be used as a method to determine whether blood flow in your coronary arteries is normal through an area with plaque. But a stress test cannot be used to gauge whether plaque has grown. It's as simple as that. Gauging plaque growth requires a heart scan.
Patient-napping: Yet another reason to stay clear of hospitals! 26. June 2006 William Davis (1) When I started practicing medicine around 20 years ago, it was common practice to alert a physician when their patient was seen in an emergency room. If John Smith, for example, went to the emergency room with chest pain, the physician who had an established relationship with the patient--knew their history, had managed their health and illnesses, etc.--was notified, even if the hospital ER had no relationship with the physician. It was not uncommon for the patient to then be transferred to the hospital where their own doctor practiced. Though cumbersome at times, it preserved the relationship of the patient with their doctor. Over the past few years, this practice has crumbled. Nowadays, hospitals and their employed physicians (and other unscrupulous physicians acting in the name of profit) "fail" to notify the physician with an established relationship. Guess what happens? The patient all too often ends up being put through the gamut of testing and procedures. Why? For hospital profit, of course. If failure to notify a doctor who's had a 10-year long relationship with the patient is "overlooked" or, even more commonly, it's "unsafe" to transfer the patient because the patient is too "unstable" to be transferred, then this patient becomes ripe for picking--heart catheterization, stents, bypass surgery, etc. Ten's, if not hundreds, of thousands of dollars can be reaped by this deception. I call it "patient-napping".I see this at least several times every month. As hospitals are becoming increasingly competitive, and as they put pressure on their physicians to churn patients for revenues, you're going to see more and more of this. As always, what is your protection from this expanding influence of hospitals and the doctors too meek to stand up to them? Education and information. Arm yourself with an understanding of what is accomplished in hospitals, when you truly need them, and when you don't. Take it one step further. At least from a heart disease standpoint--the #1 profit-maker for hospitals--aim to 1)identify your coronary plaque, then 2) seize control over your coronary plaque and reduce your risk for heart attack and heart procedures as much as humanly possible. That's the goal of the Track Your Plaque program.
