Plaquology

13. October 2008 William Davis (3)
Plaquology: A new term.

Plaquology: def: (plaque-: atherosclerotic plaque; -ology: study of.) The study of atherosclerotic plaque, originating in the early 21st century during the time period when the material underlying atherosclerosis gained recognition as a measure superior to "risk factors" for cardiovascular disease. Previous to the plaque concept, blood measures of cholesterol and adverse lifestyle habits, such as smoking and sedentary lifestyle, alone had been used to predict potential for cardiovascular events. With acceptance of the concept of plaque measurement, the concept of risk factors was abandoned.


Look it up in the current Oxford Dictionary of the English Language, or Webster's Dictionary, and I'm afraid that you still won't find plaquology . . . but you should.

I'm currently rewriting many parts of the Track Your Plaque book. The rewriting process has caused me to review just how much we've learned these past few years. One of the phenomena that fascinates me is that we now have non-medical people--teachers, software people, engineers, bankers, bed and breakfast owners, retired businesspeople, etc.--all discussing the finer points of coronary atherosclerotic plaque--plaquology--what constitutes plaque, what triggers plaque inflammation, how to quantify potential for plaque rupture or plaque quiescence, what effect various treatments have on plaque composition and behavior, etc.

We now have a legion of Plaquologists!

I'm very proud of our Plaquologists. Having devoted themselves to the study of plaque, their level of knowledge now exceeds that of 99% of practicing physicians, including my colleagues, the cardiologists. While cardiologists spend their day squashing/cutting/vaporizing plaque, they are no more experts in plaquology than a carpenter is an expert in trees. More often than not, cardiologists view plaque as just something that gets in their way, rather than the quantifiable, modifiable, reversible material that we can exert control over.

One of the software tools currently in the works for the Track Your Plaque website is a certification process. Members will be able to gain a "certification" in various topics relevant to plaquology, such as plaque quantification, lipoprotein testing, and nutritional supplements.

How about a Doctor of Plaquology?

Thyroid perspective update

10. October 2008 William Davis (18)
Since the publication of the extraordinary HUNT Study relating the entire spectrum of thyroid function and heart issues, I have been vigorously and systematically examining thyroid function in numerous patients.

While there's no news in relating flagrant low thyroid function with triggering heart disease in several forms, the cut-off between low thyroid and normal thyroid has been a matter of dispute for decades.

In the early 20th century, low thyroid function wasn't diagnosed until someone gained 40 lbs, displayed extravagant amounts of edema (water retention) in the legs and huge bags under the eyes, hair fell out in clumps, and often eventually proved fatal. At autopsy, these unfortunates also showed advanced and extensive quantities of coronary atherosclerotic plaque.

Low thyroid is usually diagnosed on the basis of the blood test, thyroid stimulating hormone, or TSH. TSH is a pituitary gland hormone responsible for stimulation of thyroid function. When thyroid function flags, the pituitary increases TSH release. Thus, a high TSH signals lower thyroid hormone levels.

The difficulty is in distinguishing normal thyroid function from low thyroid function judged by TSH levels. As the years have passed, in fact, the cut-off for "normal" TSH has drifted lower and lower.

The HUNT Study, I believe, clinches the argument: A TSH of 1.5 or lower, perhaps even 1.0 or lower, is desirable to eliminate the excess cardiovascular risk provided by an underactive thyroid, not to mention feel better: more energetic, clearer thinking, greater well-being.

Having now applied this renewed appreciation for thyroid, I have come to believe that:

--Low thyroid function, even subtle levels, are rampant and far more common than ever previously thought. In my office practice, the case could be made that several people per day are marginally or mildly hypothyroid (low in thyroid).
--Restoration of optimal thyroid levels facilitates correction of lipid measures, especially LDL cholesterol and, to a lesser degree, lipoprotein patterns dependent on the insulin axis such as triglycerides and small LDL. It's a lot happier way to correct lipids than statins.

I don't discount the value of feeling better. People who feel better--more energetic, more upbeat, clearer thinking--tend to do better in health overall. If thyroid restoration is a part of that equation, then greater attention should be paid to this facet of health on our way to optimal heart health.

Though I sometimes feel like an endocrinologist dispensing desiccated thyroid (rarely the synthetic T4), I believe that this has been a previously neglected and important part of our effort to achieve coronary plaque stabilization and reversal.

Accidental Health

9. October 2008 William Davis (2)

"I shall never have smallpox for I have had cowpox; I shall never
have an ugly pockmarked face."

Such was the idle comment made by a milkmaid to Edward Jenner in 1768 when Jenner was 19, a remark that later prompted his investigations into using isolates of cowpox injected into humans as the first vaccination against the devastations of the European epidemic of smallpox.

(A caricature of Jenner administering cowpox vaccine to people, causing them to sprout bovine appendages. Image courtesy Wikipedia and the Library of Congress.)

When I look back, something similar has happened here.

Although the Track Your Plaque program is intended to stop and reverse coronary plaque using the only available means of tracking coronary plaque, i.e., heart scans, an unintended panel of benefits follow:

--People lose weight, often dramatically
--People gain greater energy
--Thinking is clearer, emotions more stable
--Sleep is deeper
--Bone density increases
--Physical strength and coordination improve
--Winter blues dissipate
--Blood sugar drops dramatically
--Blood pressure drops

Cholesterol (lipid) panels also settle to values that most physicians deem impossible or impractical, given our target of 60:60:60, i.e., LDL 60 mg/dl or less, HDL 60 mg/dl or higher, triglycerides 60 mg/dl or less. And medications are not always necessary to achieve these values. (When I show these values to my colleagues, they declare them flukes, unobtainable only in select people with high doses of medications.)

I didn’t set out to find the next weight loss solution, nor the key to boundless energy. My goal was "simpler": create a program of heart health. I am, after all, a cardiologist.

I was so intently focused on achieving incremental improvements over the steps leading to heart disease prevention that I failed to recognize the profound phenomena that accompanied it: people were quicker, smarter, thinner, and healthier.

In other words, I believe that we have inadvertently created a program of super health and performance.

Ironically, most people don't want to talk about heart disease, let alone reversal of heart disease. They do want to talk about getting thinner, feeling more energetic, living longer, better cholesterol values, etc.

Perhaps there's a lesson in this.

Livin' La Vida Low Carb interview

7. October 2008 William Davis (5)

I recently provided an interview for Livin' La Vida Low Carb's irrepressible Jimmy Moore.

Jimmy runs a fun set of blogs, webcasts, and the like to broadcast this message of reducing carbohydrates in the diet. He credits his 210 lb weight loss to a strict low-carbohydrate and exercise program.

For the interview, just go to The Livin' the Vida Low Carb Show, Episode 185, or click here.

And click here for Part 2


For more of Jimmy Moore's spin on the entire low-carbohydrate diet experience, he maintains several popular blogs, including Carb Wire and The Livin' La Vida Low-Carb Blog.

Wheat withdrawal: How common?

5. October 2008 William Davis (11)
In response to the recent Heart Scan Blog poll,

Have you experienced fatigue and mental fogginess with stopping wheat, i.e., "wheat withdrawal"?

the 104 respondents said:


Yes, I have experienced it: 26 (25%)

No, I stopped wheat and did not experience it: 65 (62%)

I'm not sure: 3 (2%)

I haven't tried it but plan to: 7 (6%)

I haven't tried it and don't plan to: 3 (2%)


So 25% of respondents reported experiencing the fatigue and mental fogginess of wheat withdrawal. This is similar to what I observe in my practice.

I counsel many patients to consider the elimination of wheat, as well as cornstarch products, in an effort to regain control over:

--Weight
--Appetite
--Low HDL
--High triglycerides
--Small LDL
--High blood sugar
--High blood pressure

All of these issues respond--often dramatically--to elimination of wheat and cornstarch.

Why would there be undesirable effects of eliminating wheat?

One clear issue is that elimination of wheat and other sugar-equivalents deprives your body of glucose. Your body then needs to resort to fatty acid metabolism to generate energy. Apparently, some people are inefficient at this conversion, having subsisted on carbohydrates for the last few decades of their lives. However, as fatty acid metabolism kicks in, energy generation improves. That is my (over-)simplified way of reasoning it through.

However, are there other explanations behind the mental fogginess, drop in energy, and overwhelming sleepiness? Some readers of this blog have suggested that, since opioid-like sequences (i.e., amino acide sequences that activate opiate receptors) are present in wheat, perhaps withdrawal from wheat represents a lesser form of opiate withdrawal. I find this a fascinating possibility, though I know of no literature devoted to establishing a cause-effect relationship.

Whatever the mechanism, I find it very peculiar that this food widely touted by the USDA, American Heart Association, and other agencies actually triggers a withdrawal syndrome in approximately 25% of people. Spinach does not trigger withdrawal. Nor does flaxseed, olive oil, almonds, and countless other healthy foods.

Then why would whole wheat grains be lumped with other healthy foods?

Treat the patient, not the test

5. October 2008 William Davis (0)
"Treat the patient, not the test."

That is a common "pearl" of medical wisdom often passed on during medical training.

It refers to the fact that we should always view any laboratory or imaging test in the context of the live, human patient and not just treat any unexpected value that doesn't seem to make sense.

I raise this issue because it recently came up on a discussion on the Track Your Plaque Forum. A Member with a high heart scan score of around 1100 was advised by his doctor that it should be ignored, because he'd prefer to treat the patient, not the test. The patient is apparently slender, physically active, and entirely without symptoms, with favorable cholesterol values as well. The high heart scan score didn't seem to jive with the appearance of the patient, as viewed by this doctor.

This common phrase is meant to impart wisdom. It is a reminder that we treat real people, not just a jumble of laboratory values.

But the unspoken part of the equation is that judgment needs to be applied. A well looking person who shows an unexpected rise in white blood cell count could just have a screwy result, or could have leukemia. Liver tests (AST, ALT) that top 400 could represent a fluke, or dehydration incurred during a long workout, or hepatitis from a long ago blood transfusion.

Yes, treat the patient. But don't be an idiot and entirely dismiss the signficance of an unexpected laboratory or imaging test. A heart scan score of 1100 should be as readily dismissed as discovering a white blood cell count of 90,000 (normal is less than 12,000), or a 5 cm mass in the lung. The absence of symptoms or the failure of conventional risk factors to suggest causation is insufficient reason to dismiss the concrete findings of a test.

In this particular person, dismissing the significance of the heart scan finding by suggesting that the doctor should treat the patient, not the test, is tantamount to:

--Colossal ignorance
--Malpractice
--A certain sentencing of the hapless patient to future major heart procedures, heart attack or death (20-25% likelihood every year, or a virtual certainty over the next 5 years).

There is an ounce of wisdom in this old medical pearl. But there's also plenty of room for a knuckleheaded doctor to misconstrue and abuse its meaning for the sake of covering up his/her ignorance, laziness, or lack of caring.

Does high cholesterol cause heart disease?

3. October 2008 William Davis (15)
How often does someone develop coronary heart disease from high cholesterol alone?

Believe drug industry propaganda and you'd think that everyone does. Physicians have bought into this concept also, driving the $27 billion annual sales in statin cholesterol drugs.

In my experience, I can count the number of people who develop coronary disease from high cholesterol alone on one hand. It happens--but rarely.

That's not to say that cholesterol is not an issue. That rant populates many of the kook websites and conversations on the internet that argue that high cholesterol is a surrogate for some other health issue, or that it is part of a medical conspiracy.

The problem with conventional measurement of cholesterol is that it ignores the particle size issue: whether particles are large or small. Small LDL are flagrant causes of coronary atherosclerotic plaque. Large LDL is a rather meager cause. Simple cholesterol measurement also ignores the presence of other factors that lead to heart disease, like lipoprotein(a) and vitamin D deficiency.

Conventional total and LDL cholesterol do not distinguish between large and small particles, nor reveal the presence of other hidden patterns. An LDL cholesterol of 150 mg/dl, for instance, may contain 100% large LDL--a relatively good situation that by itself is unlikely to cause heart disease, or it might contain 100% small LDL--a very bad situation that is likely to cause heart disease. Just knowing that LDL is 150 mg/dl tells you almost nothing. In 2008, most people have some mixture of the two, particularly with the proliferation of "healthy whole grains" in the American diet, foods that trigger formation of small LDL.

The imprecision and uncertainty of conventional total and LDL cholesterol has provided ammunition for some to discount the entire cholesterol concept. And they are right to a degree: cholesterol by itself is indeed a lousy predictor of heart disease. But small LDL is a very reliable predictor of potential for heart disease. Dismissing the entire concept because the standard measurement stinks is not right, either.

It is therefore an unfortunate oversimplification to say that high cholesterol causes heart disease or that it doesn't. It can--but not always, depending on size and other factors. In my view, it is therefore irreponsible to treat total or LDL cholesterol without knowledge of particle size. I've seen this play out many times: Someone with an LDL cholesterol of 150 mg/dl but all large still gets prescribed a statin drug by his/her doctor. Or someone with an LDL of 100 mg/dl--generally "favorable" by most standards--is not treated but it is all small and the person is truly at high risk. (Also, knowledge that all LDL particles are small does not mean that statins are the preferred agent. In my view, they are not.)

Are humans meant to be omnivores?

28. September 2008 William Davis (24)
Are humans meant to be omnivores?

Does the ideal human diet include animal products like meat, fish, cheese, eggs, and dairy products?

Or should the ideal diet be devoid of all animal products?a vegetarian diet?

Though the argument is distorted by modern food processing methods (e.g., factory farming, long-term administration of antibiotics), convenience foods, and pseudo-foods crafted by food manufacturers, there are, obviously, proponents of both extremes.

The Atkins’ diet, for instance, advocates unrestricted intake of animal products, regardless of production methods or curing (sausage and bacon). At the opposite extreme are diets like Ornish (Dr. Dean Ornish’s Program for Reversal of Heart Disease) and the experiences of Dr. Colin Campbell, articulated in his studies and book, The China Study, in which he lambasts animal products, including dairy, as triggers for cancer and heart disease.

So which end of the spectrum is correct? Or ideal?

For the sake of argument, let's put aside philosophical questions (like not wanting eat animal products because of aversion to killing any living being) or ethical concerns (inhumane treatment of farm animals, cruel slaughtering practices, etc.). Does the inclusion of animal products provide advantage? Disadvantage?

The traditional argument against animal products has been saturated fat. If we accept that we’ve demoted the saturated fat question to a place far down the list of importance (though this is yet another argument to discuss another time), several questions emerge:

• If humans were meant to be vegetarian, why do omega-3 fatty acids (mostly from wild game and fish) yield such substantial health benefits, including dramatic reduction in sudden death from heart disease?

• Why would vitamin K2 (from meats and milk, as well as fermented foods like natto and cheese), obtainable in only the tiniest amounts on a vegetarian diet, provide such significant benefits on bone and cardiovascular health?

• Why would vitamin B12 (from meats) be necessary to maintain a normal blood count, prevent anemia, keep homocysteine at bay, and lead to profound neurologic dysfunction when deficient?


Omega-3 fatty acids and vitamins K2 and B12 cannot be obtained in satisfactory quantities from a pure vegetarian diet. The consequences of deficiency are not measured in decades, but in a few years. The conclusion is unavoidable: Evolutionarily, humans are meant to consume at least some foods from animal sources.

That's not to say that we should gorge ourselves on animal products. Gout (excessive uric acid) and kidney stones are among the unhealthy consequences of excessive quantities of meats in our diets.

It pains me to say this, since I’ve always favored a vegetarian lifestyle, mostly because of philosophical concerns, as well as worries about the safety of our factory farm-raised livestock and rampant inhumane practices.

But, stepping back and objectively examining what nutritional approach appears to stack the odds in favor of optimal health, I believe that only one conclusion is possible: Humans are meant to be omnivorous, meant to consume some quantity of animal products in addition to vegetables, fruits, nuts, and other non-animal products.

The question is how much?

Are you wheat-free?

24. September 2008 William Davis (25)
According to the recent Heart Scan Blog poll, Are you wheat-free?, the 173 respondents said:

Yes, I am free of wheat products.
87 (50%)

No, I include wheat products in my diet.
73 (42%)

I'm not sure.
1 (0%)

I think you're nuts.
12 (6%)


That's kind of what I expected.

There are people who have eliminated wheat and experienced nothing except a feeling of deprivation. These people are in the minority. Though the poll was not set up to reflect this (i.e., asked who tried it and experienced no perceptible benefit), in my experience, this applies to about 20% of people. Little happens with elimination of wheat beyond modest weight loss. Those are the people who generally think I'm nuts.

Or, these people may have been brainwashed by "official" agencies like the USDA, the American Diabetes Association, and American Heart Association and the constant marketing of (high markup) grain products like Cheerios and Shredded Wheat . Some people are really uncomfortable going against the "grain" of popular public opinion.

Then there are the people who try to eliminate wheat and fail. They can't deal with the overwhelming fatigue, mental fog, and moodiness that comes with withdrawal from wheat, the phenomenon of converting from a sugar-burning metabolism to a fat-burning metabolism. Although wheat withdrawal usually runs its course in 2-5 days, some people find it intolerable. (That would be another fun poll to run: Have you experienced wheat-withdrawal?) Occasionally, the withdrawal is replaced by endless cravings, a phenomenon that applies to only about 10% of people. These are the true "wheat addicts." These are the people who eliminate wheat, lose 40 lbs, then regain it when they have one cracker and the floodgates of impulse control crumble.

Then there are the majority, 50% in the poll, though more like 70% in my face-to-face experience. Why is my experience skewed? Well, the people I deal with every day come because of coronary disease in some form (abnormal heart scan score, for instance) or because of lipid or lipoprotein abnormalities. So my experienced is skewed towards people who are likely to have something abnormal, such as high triglycerides or small LDL particles, both of which are created by including wheat in the diet.

This last group also shows unexpected effects of wheat elimination: substantial weight loss, dramatic reductions in blood sugar and triglycerides, increase in HDL, reductions in small LDL, reduction in c-reactive protein and other inflammatory measures. Appetite shrinks considerably. Not uncommonly, improved well-being, reduction in bowel complaints like cramping or "irritable bowel syndrome" is experienced, some rashes clear, occasionally arthritis will improve. See below for some of the testimonials to this experience.

When I first set out to advise people to eliminate wheat, I did it because I reasoned that it would be a quick and simple way to get people to reduce blood sugars and help correct the ubiquitous metabolic syndrome that afflicts nearly 50 million Americans now. And it did indeed accomplish that simple goal. But I did not expect all the other benefits to develop, the dramatic weight loss, improved well-being, reduction in hunger, etc.

I view wheat elimination as an easy-to-remember, digestible way to obtain enormous health benefits in a coronary plaque-control program, one that works for most--but not all--people. And I relate this experience not to sell you something, but to simply relate what I see as the truth, a way that is contrary to conventional advice yet works enormously well.



Unsolicited testimonials of people who have successfully been wheat-free:

Barbara W said:

It's true! We've done it. My husband and I stopped eating all grains and sugar in February. At this point, we really don't miss them any more. It was a huge change, but it's worth the effort. I've lost over 20 pounds (10 to go)and my husband has lost 45 pounds (20 to go). On top of it, our body shapes have changed drastically. It is really amazing. I've got my waist back (and a whole wardrobe of clothes) - I'm thrilled.

I'm also very happy to be eating foods that I always loved like eggs, avocados, and meats - without feeling guilty that they're not good for me.

With the extremely hot weather this week in our area, we thought we'd "treat" ourselves to small ice cream cones. To our surprise, it wasn't that much of a treat. Didn't even taste as good as we'd anticipated. I know I would have been much more satisfied with a snack of smoked salmon with fresh dill, capers, chopped onion and drizzled with lemon juice.

Aside from weight changes, we both feel so much better in general - feel much more alert and move around with much greater flexibility, sleep well, never have any indigestion. We're really enjoying this. It's like feeling younger.

It's not a diet for us. This will be the way we eat from now on. Actually, we think our food has become more interesting and varied since giving up all the "white stuff". I guess we felt compelled to get a little more creative.

Eating out (or at other peoples' places) has probably been the hardest part of this adjustment. But now we're getting pretty comfortable saying what we won't eat. I'm starting to enjoy the reactions it produces.


Weight loss, increased energy, less abdominal bloating, better sleep--I've seen it many times, as well.


Dotslady said:

I was a victim of the '80s lowfat diet craze - doc told me I was obese, gave me the Standard American Diet and said to watch my fat (I'm not a big meat eater, didn't like mayo ... couldn't figure out where my fat was coming from! maybe the fries - I will admit I liked fries). I looked to the USDA food pyramid and to increase my fiber for the constipation I was experiencing. Bread with 3 grams of fiber wasn't good enough; I turned to Kashi cereals for 11 years. My constipation turned to steattorrhea and a celiac disease diagnosis! *No gut pains!* My PCP sent me to the gastroenterologist for a colonscopy because my ferritin was a 5 (20 is low range). Good thing I googled around and asked him to do an endoscopy or I'd be a zombie by now.

My symptoms were depression & anxiety, eczema, GERD, hypothyroidism, mild dizziness, tripping, Alzheimer's-like memory problems, insomnia, heart palpitations, fibromyalgia, worsening eyesight, mild cardiomyopathy, to name a few.

After six months gluten-free, I asked my gastroenterologist about feeling full early ... he said he didn't know what I was talking about! *shrug*

But *I* knew -- it was the gluten/starches! My satiety level has totally changed, and for the first time in my life I feel NORMAL!


Feeling satisfied with less is a prominent effect in my experience, too. You need to eat less, you're driven to snack less, less likely to give in to those evil little bedtime or middle-of-the-night impulses that make you feel ashamed and guilty.



An anonymous (female) commenter said:

My life changed when I cut not only all wheat, but all grains from my diet.

For the first time in my life, I was no longer hungry -no hunger pangs between meals; no overwhelming desire to snack. Now I eat at mealtimes without even thinking about food in between.

I've dropped 70 pounds, effortlessly, come off high blood pressure meds and control my blood sugar without medication.

I don't know whether it was just the elimination of grain, especially wheat, or whether it was a combination of grain elimnation along with a number of other changes, but I do know that mere reduction of grain consumption still left me hungry. It wasn't until I elimnated it that the overwhelming redution in appetite kicked in.

As a former wheat-addicted vegetarian, who thought she was eating healthily according to all the expert advice out there at the time, I can only shake my head at how mistaken I was.



Stan said:

It's worth it and you won't look back!

Many things will improve, not just weight reduction: you will think clearer, your reflexes will improve, your breathing rate will go down, your blood pressure will normalize. You will never or rarely have a fever or viral infections like cold or flu. You will become more resistant to cold temperature and you will rarely feel tired, ever!


Ortcloud said:

Whenever I go out to breakfast I look around and I am in shock at what people eat for breakfast. Big stack of pancakes, fruit, fruit juice syrup, just like you said. This is not breakfast, this is dessert ! It has the same sugar and nutrition as a birthday cake, would anyone think cake is ok for breakfast ? No, but that is exactly the equivalent of what they are eating. Somehow we have been duped to think this is ok. For me, I typically eat an omelette when I go out, low carb and no sugar. I dont eat wheat but invariably it comes with the meal and I try to tell the waitress no thanks, they are stunned. They try to push some other type of wheat or sugar product on me instead, finally I have to tell them I dont eat wheat and they are doubly stunned. They cant comprehend it. We have a long way to go in terms of re-education.

Yes. Don't be surprised at the incomprehension, the rolled eyes, even the anger that can sometimes result. Imagine that told you that the food you've come to rely on and love is killing you!


Anne said:

I was overweight by only about 15lbs and I was having pitting edema in my legs and shortness of breath. My cardiologist and I were discussing the possible need of an angiogram. I was three years out from heart bypass surgery.

Before we could schedule the procedure, I tested positive for gluten sensitivity through www.enterolab.com. I eliminated not only wheat but also barley and rye and oats(very contaminated with wheat) from my diet. Within a few weeks my edema was gone, my energy was up and I was no longer short of breath. I lost about 10 lbs. The main reason I gave up gluten was to see if I could stop the progression of my peripheral neuropathy. Getting off wheat and other gluten grains has given me back my life. I have been gluten free for 4 years and feel younger than I have in many years.

There are many gluten free processed foods, but I have found I feel my best when I stick with whole foods.


Ann has a different reason (gluten enteropathy, or celiac disease) for wanting to be wheat-free. But I've seen similar improvements that go beyond just relief of the symptoms attributable to the inflammatory intestinal effects of gluten elimination.



Wccaguy said:

I have relatively successfully cut carbs and grains from my diet thus far.

Because I've got some weight to lose, I have tried to keep the carb count low and I've lost 15 pounds since then.

I have also been very surprised at the significant reduction in my appetite. I've read about the experience of others with regard to appetite reduction and couldn't really imagine that it could happen for me too. But it has.

A few weeks ago, I attended a party catered by one of my favorite italian restaurants and got myself offtrack for two days. Then it took me a couple of days to get back on track because my appetite returned.

Check out Jimmy Moore's website for lots of ideas about variations of foods to try. The latest thing I picked up from Jimmy is the good old-fashioned hard boiled egg. Two or three eggs with some spicy hot sauce for breakfast and a handful of almonds mid-morning plus a couple glasses of water and I'm good for the morning no problem.

I find myself thinking about lunch not because I'm really hungry but out of habit.

The cool thing too now is that the more I do this, the more I'm just not tempted much to do anything but this diet.

No more canned foods

21. September 2008 William Davis (12)
If you haven't already caught the news, it's time to eliminate canned foods and exposure to plastics that contain the chemical, bisphenol A (BPA). A worrisome and unexpected association with heart disease and diabetes has been found.

This issue has been debated for some years ever since scientists at the NIH detected BPA in the blood samples of 93-95% of Americans, with consumer protection advocates calling for more research or even the outright banning of BPA , while industry representatives have argued that the data fail to conclusively prove adverse health effects.

Well, the argument has been tilted heavily in favor of increased consumer protection with the publication of a study in the Journal of the American Medical Association by Dr. Iain Lang and associates at the University of Exeter, UK, and the University of Iowa. Their study, released Sept. 17, 2008, Association of urinary bisphenol A concentration with medical disorders and laboratory abnormalities in adults, persuasively demonstrated a 40% increased incidence of coronary heart disease, heart attack, and diabetes with increasing exposure to BPA (as judged by urine levels) among the nearly 1500 adults aged 18-74 years. People with coronary heart disease had double the blood level of BPA compared to those without.

In addition, higher urine levels of BPA were associated with abnormalities of two liver tests, GGT and alkaline phosphatase.

Interestingly, although much of the debate over adverse health effects of BPA have centered around concern over cancer and reproductive risks, an association with cancer did not hold. (No analysis for reproductive issues was conducted in these adults, since most of the concern is for children exposed through polycarbonate baby bottle use. Some BPA critics have raised questions like low birth weight developing from exposure.) No relationship to thyroid disease was identified, also.

The editorial accompanying the study added some sharp commentary:

"Subsequent to an unexpected observation in 1997, numerous laboratory animal studies have identified low-dose drug-like effects of BPA at levels less than the dose used by the US Food and Drug Administration and the Environmental Protection Agency to estimate the current human acceptable daily intake dose (ADI) deemed safe for humans. These studies have shown adverse effects of BPA on the brain, reproductive system, and--most relevant to the findings of Lang et al--metabolic processes, including alterations in insulin homeostasis and liver enzymes. . . For example, when adults rats were fed a 0.2 microgram/kg per day dose of BPA for 1 month (a dose 250 times lower than the current ADI), BPA significantly decreased the activities of antioxidant enzymes and increased lipid peroxidation, thereby increasing oxidative stress. When adult mice were administered a 10 microgram/kg dose of BPA once a day for 2 days ( a dose 5 times lower than the ADI), BPA stimulated pancreatic beta cells to release insulin."

This study, piled on top of the worrisome literature that precede it, are enough for me: No more tin cans (which are lined with BPA), no more hard plastics labeled with recycling code #7 or #3, no more polycarbonate water bottles (the hard ones, often brightly colored). Microwaveable-safe may also mean human-unsafe, as highlighted by this damning assurance from the Tupperware people that BPA is not a health hazard.

The National Toxicology Program also issued these advice in response to the Lang study to reduce BPA exposure (reported by the Washington Post) :

· Don't microwave polycarbonate plastic food containers. Polycarbonate may break down from overuse at high temperatures and release BPA. (Manufacturers are not required to disclose whether an item contains BPA, but polycarbonate containers that do usually have a No. 7 on the bottom.)

· Reduce use of canned foods, especially acidic foods such as tomatoes that can accelerate leaching of BPA from plastic can linings. Opt for soups, vegetables and other items packaged in cardboard "brick" cartons, made of safer layers of aluminum and polyethylene plastic (labeled No. 2).

· Switch to glass, porcelain or stainless-steel containers, particularly for hot food or liquids.

· Use baby bottles that are BPA-free; in the past year, most major manufacturers have developed bottles made without BPA.

Self-directed health: At-home lab testing

29. March 2009 William Davis (20)
I have a prediction.

I predict that more and more healthcare can and will be obtained directly by the individual--without doctors, without hospitals, without the corrupt profit-at-any-costs modus operandi of the pharmaceutical industry. I predict that, given the right tools, Joe or Jane Q. Public will have the choice to manage his or her own health using tools that are directly accessible, tools that include direct-to-consumer medical imaging (CT scans, ultrasound, MRI, etc.), nutritional supplements (a loosely-defined term, to our advantage), and direct-to-consumer laboratory testing.

Done responsibly, self-directed healthcare is superior to healthcare from your doctor. While no one expects you to remove your own gallbladder, you can manage cholesterol, blood sugar issues, vitamin D, low thyroid, and others--better than your doctor.

As everyone becomes more comfortable with the notion of self-directed health, you will see new services appear that help individuals manage their health. You will see prices for direct-to-consumer medical imaging and lab testing drop due to competition, something that doesn't happen in current insurance-based healthcare delivery. People are being exposed to larger deductibles and/or draw money from a medical savings account and will seek more cost advantages. Such direct-to-consumer competitive pricing will meet those needs. Overall, the presently unsustainable cost of healthcare will decline.

To help accelerate the shift of human healthcare away from conventional paths and divert it towards the individual, we have launched a panel of direct-to-consumer at-home laboratory tests that we are making available on the Track Your Plaque website.

On your own (except in California, which requires a doctor's order or prescription; and NY, the only state in the nation that prohibits entirely), you can now test, in the comfort of your own home with no laboratory blood draw required, parameters including:

--Thyroid tests--Free T3, free T4, TSH
--Lipids
--C-reactive protein
--Vitamin D
--Testosterone
--Progesterone

and others.

As the technology improves, more tests will become available for testing at home. (Lipoproteins are not yet available, but will probably be available within the next few years. That would be an enormous boon to those of us interested in supercharged heart disease prevention and reversal.)

Anyone interested in our at-home testing can just go to the Track Your Plaque lab test Marketplace.

When I first began the Track Your Plaque program around 8 years ago, I saw it as a way for people to learn how to control or reverse coronary atherosclerotic plaque, and I'd hoped that physicians would begin to see the light and become patient advocates in this process. But I have lost hope that most of my colleagues are interested in becoming your advocate in health. They are too locked into the "call me when you hurt" mentality. I now see Track Your Plaque as a way for people to seize control over coronary plaque with minimal assistance from their doctors. Indeed, some of our Members have achieved reduction of their plaque in spite of their doctors.

This is just the tip of the iceberg of what's to come. Brace yourself for a cataclysmic shift in returning health to you and away from those who would profit from your misfortune.

Vitamin D for Peter, Paul, and Mary

27. March 2009 William Davis (15)
Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D.

It means that vitamin D deficiency sustained over many years in:

Peter yields prostate cancer

Paul yields coronary heart disease and diabetes

Mary yields osteoporosis and knee arthritis.


Same deficiency, different diseases.

VDR genotype-determined susceptibility to numerous conditions have been identified, including Graves' thyroiditis, osteoporosis and related bone demineralization diseases, prostate cancer (Fok1 ffI genotype), ovarian cancer, rheumatoid arthritis, breast cancer (Fok1 ff), birth weight of newborns, melanoma and non-melanoma skin cancers, insulin resistance and metabolic syndrome, susceptibility to type I diabetes, Crohn's disease, and neurological or musculoskeletal deterioration with aging that leads to falls, respiratory infections, kidney cancer, even periodontal disease.


Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.

Should we all run out and get our VDR genotypes assessed? So far the data have not progressed far enough to tell us. If, for instance, you prove to have the high-risk Fok1 ff genotype, would you do anything different? Would vitamin D supplementation be conducted any differently? I don't believe so.

Virtually all of us should be supplementing vitamin D at a dose that generates healthy blood levels, regardless of VDR genotype. For those of us following the Track Your Plaque program for coronary plaque control and reversal, that means maintaining serum 25-hydroxy vitamin D levels between 60-70 ng/ml.

As the fascinating research behind VDR genotype susceptibility to disease unfolds, perhaps it will suggest that specific genotypes be somehow managed differently. Until then, take your vitamin D.

Blowup at Milwaukee Heart Scan

26. March 2009 William Davis (20)
A local TV investigative news report just ran a critical report of the goings-on at Milwaukee Heart Scan:

Andy Smith went to Milwaukee Heart Scan. "It passed the smell test like a road kill skunk. I mean it was bad," Smith explained.

Our hidden cameras went inside the high pressure sales pitch. "On a good day I sell eight, nine, 10 people. On a bad day probably three," sales manager Angelo Callegari told us.


What the heck happened?

Let me tell you a story.

Back in 1996, I learned of a new technology called UltraFast CT scanning, or electron-beam tomography (EBT), a variation on the standard CT technology that permitted very rapid scanning, sufficiently rapid to allow visualization of the coronary arteries. Back then, only a few dozen devices had been established nationwide.

But the technology was so promising and the initial data so powerful that I lobbied several hospital systems in town to consider purchasing one of the $1.8 million devices. I was interested in applying this exciting technology for early detection of coronary heart disease in Milwaukee. While administrators from several hospitals listened, they quickly lost interest when they figured out that the scanner was primarily a tool for prevention, and would not be directly useful to increase revenue-generating hospital procedures.

I floundered about for a year, trying to drum up support for obtaining a scanner. The manufacturer of the device, Imatron, put me in touch with a couple from Indiana who were also interested in setting up a scanner and had actually obtained the investment capital to do it. We met and, over the next year, got Milwaukee Heart Scan up and running. I served as Medical Director (but never an investor or owner).

Milwaukee Heart Scan was busy from day one, performing EBT heart scans, as well as CT coronary angiograms as long ago as the late 1990s, virtual colonoscopies, and other imaging tests. We all spent a great deal of time educating the public and physicians on what this technology meant for detection and prevention of disease.

Despite the public's perception that the owners, Nancy and Steve Burlingame, were making a bundle of money, in reality they could barely pay their expenses. As price competition heated up in Milwaukee with the lower-cost competing multidetector scanners cropping up, the Burlingames often did not pay themselves.

My interest was to keep this device afloat. I therefore told the Burlingames that they should pay their bills first--their staff, overhead, the scanner costs, and pay themselves--and not worry about reimbursing me for the (very modest) heart scan interpretation fees. For several years, I read thousands of scans without any compensation. But that was okay with me--I just wanted to be sure this device remained available.

But in 2008, some business people from Chicago contacted Steve Burlingame with prospects of applying a contract model of long-term scanning to patients,i.e.,getting people to sign a several-year contract for discounted imaging. They proposed that Milwaukee Heart Scan offer heart scans for free to get people in the door.

What was peculiar about all this is that none of the four physicians on staff at Milwaukee Heart Scan had any knowledge of these discussions at all, including myself. Personally, I figured something was afoot when I came in to read scans in the summer of 2008. While, ordinarily, there is a single stack of scans to read from the preceding few days, this time there were numerous stacks of scans, hundreds of scans in all. Not a word had been said to me or my colleagues. I quickly figured out (thanks to the staff filling me in) that they had been offering scans for free. Not surprisingly, many people took them up on the offer.

Up until then, I had been readily willing to read heart scans without compensation, provided I could perform scan readings in a modest time commitment every week on the weeks it was my responsibility. But work several hours every day for free? Impossible.

My colleagues and I were deeply upset and concerned and insisted on a meeting with all the people involved, including the Burlingames, who had engineered this new sales program. We expressed serious reservations about what they were doing and insisted that they dramatically scale back the promises being made to people. I personally asked that they fire several of the people they had hired as sales people, given what we thought was unprofessional appearance and behavior.

The Burlingames and their new business partners essentially thumbed their noses at the physicians and ignored our advice. So, of the four physicians (one radiologist, three cardiologists), three of us resigned. (The one remaining cardiologist, I believe, didn't really understand what was going on.)

Apparently, after we left, the hard sales tactics continued. The news media got hold of the story through some understandably disgruntled people, and you know the rest.

The tragedy in all this is that, as wonderful as heart scans are, they don't make money for the people who invest in the technology. In the sad case of Milwaukee Heart Scan, it meant that my former friends, the Burlingames, turned to questionable tactics to make this technology pay.

Make no mistake: Heart scans remain a wonderful medical imaging modality. EBT, in particular, remains a fabulous technology that would--even today--remain the pre-eminent means to image coronary arteries, except that GE (who acquired Imatron some years ago) decided that a more direct path to bigger revenues was to purchase Imatron, then promptly scrap the entire operation, choosing to focus on multidetector technology exclusively.

Don't let the spotty past and petty ambitions cloud the fact that heart scans remain the best way to identify and track coronary plaque. Just don't get tempted by the offer of any free scans "without obligation."

Do you work for the pharmaceutical industry?

24. March 2009 William Davis (30)
In response to my post, Lovaza Rip-off, I received this angry comment:


Very high triglycerides, as you all know, is a very serious and life-threatening condition. Therefore, it is very important that any medication you take for treatment must be FDA proven and scientifically backed. This is true for a few reasons. First, there have been zero studies done to show the effects of Costco brand fish oil pills on patients with high triglycerides. So, you cannot assume, simply because the pills you are taking "claim" to have a certain amount of Omega 3 in the them, that they actually do (supplement labeling is self-submitted by the company, and not regulated by any external or 3rd party agency).

Secondly, the other components in fish oil, and maybe in Costco brand (no one knows because it isn't on the label) can actually inhibit the bioavailablity of Omega 3, most notably, Omega 6. And, nowhere on the Costco label does it tell you how much Omega 6 is in it. We also cannot underestimate the importance of purity with these compounds: a top selling brand of fish oil found stores like CVS was recently recalled because it was found to have large amounts of fire retardant in it! These supplements are NOT regulated by the FDA.

Thirdly, be careful when you compare costs. The cost of hospitalization due to acute pancreatitis (a risk of very high triglycerides) far outweighs the cost of taking Lovaza for even several years. If you have a real disease, you need a real drug. And, until Costco does a prospective long-term clinical trial to show that it lowers triglycerides, it should not be used in place of Lovaza.

Finally, I am a living example of how taking a high-potency supplement form of Omega 3 barely lowered my triglycerides, yet within 2 weeks of being on Lovaza there was a significant difference. I am now at my goal. So, before you knock a company, that, in my opinion, has saved my life, please do your research and do not mislead people into thinking that an Omega 3 is an Omega 3 is an Omega 3. If your insurance covers the most potent, the most pure, and the ONLY proven Omega 3 pill on the market, you should be thankful.


The comment was posted anonymously, so I don't know who it came from. But I can tell who I think it is: Someone who works for the drug industry.

This is a common phenomenon: Large corporations are fearful of the comments that are generated on internet conversations and other media. On the internet, there are actually people whose job it is to do "damage control." I suspect this came from one of them.

Why bother? Surely there are better things to do? Well, that's easy. There are billions of dollars at stake. Lovaza, in particular, is sold on the perception that it is somehow superior. If word gets out that maybe you can achieve the same results at a fraction of the cost . . .

Perhaps the "commenter" should also question whether omega-3 fatty acids can come from eating fish.

As part of my cardiology practice, I provide consultation on complex hyperlipidemias, or unusual lipid abnormalities. I have many patients with something called familial hypertriglyceridemia, a genetic condition that permits triglyceride levels of 500, 1000, even many thousands of mg/dl, levels that, as the anonymous commenter points out, can be dangerous.

I virtually never prescribe Lovaza for these people. In their treatment program, I use simple fish oil supplements, such as that from Costco, Sam's Club, or other retailers. I have not witnessed a single failure in treating these people and reducing triglycerides. People with lesser triglyceride abnormalities likewise respond very nicely to inexpensive fish oil that we can buy at the health food store. (I do rely on useful services like Consumer Reports and www.consumerlab.com to reassure us that no pesticide residues, mercury, or other contaminants are in the brands we use.) Excellent, high-quality fish oil supplements are sold by Carlson, Life Extension, Barlean's, even the Members' Mark brand from Sam's Club.

So, the notion that only prescription fish oil is capable of reducing triglycerides is, in a word, nonsense.

Take that back to your CEO.

Cholesterol effects of carbohydrates

24. March 2009 William Davis (31)
Let's take a hypothetical person, say, a 50-year old male. 5 ft 10 inches, 160 lbs, BMI 23.0. He's slender and in good health.

Our hypothetical man eats a simple diet of vegetables, some fruit, nuts, and meats but avoids processed industrial foods. By macronutrient composition, his diet is approximately 30% protein, 40-50% fat, 20-30% carbohydrate. His starting lipid panel:

Total cholesterol 149 mg/dl
LDL cholesterol 80 mg/dl
HDL 60 mg/dl
Triglycerides 45 mg/dl

His starting lipids are quite favorable (though I don't often see this kind of starting panel nowadays except in athletes). We begin here because this hypothetical man is going to serve as our test subject.

We ask our hypothetical man to load his diet up on "healthy whole grains." He complies by eating whole grain cereals for breakfast, whole wheat toast; sandwiches made with whole grain bread; dinners of whole wheat pasta; snacks of granola bars, whole wheat pretzels and crackers.

Three months later, his lipids show:

Total cholesterol 175 mg/dl
LDL cholesterol 130 mg/dl
HDL 45 mg/dl
Triglycerides 150 mg/dl


You can see that LDL cholesterol has increased, HDL has dropped, and triglycerides have increased. This wave of change is the hallmark of carbohydrate excess, but more specifically of overreliance on wheat products. Beyond his lipid panel, the man has gained 10 lbs, all concentrated in a soft roll around his abdomen, his blood sugar is now in the "borderline range" of between 110 and 126 mg/dl, i.e., pre-diabetic.

If we were to examine this man's advanced lipoproteins (e.g., NMR from Liposcience, or VAP from Atherotech), we would see that there has been an explosive increase in small LDL particles, along with a shift of large HDL to small, and the appearance of multiple abnormal classes of particles called VLDL and IDL (signalling abnormally slowed clearance of dietary by-products from the blood).

Familiar scenario? The "after-carbohydrate" situation is the rule among the people who I first meet who claim to be eating a "healthy" diet, though their patterns are usually much worse, with higher LDL, lower HDL, and much higher triglycerides, an exaggeration of our hypothetical man's abnormalities.

What if our hypothetical man now goes to his conventionally thinking (read "taught medicine by the pharmaceutical industry") physician? What will likely be the advice he receives? Reduce his saturated fat intake, eat plenty of healthy whole grains, take a statin drug.

Although my illustrative man is hypothetical, I've seen this scenario play out many thousands of times. It happens in real life all the time. It is predictable, it is highly manipulable. Sadly, it is rarely recognized for what it is: the result of excess carbohydrates, or what I call "Carbohydrate Intolerance Syndrome."

The misinterpretation of this condition has created 1) an epidemic of diabetes and pre-diabetes, 2) a nation of frustrated obese Americans, 3) a $27 billion per year statin industry, 4) another growth opportunity for the drug industry in diabetes drugs.

Wheat Belly Revisited

23. March 2009 William Davis (24)
Do you have a wheat belly?

When I first coined this phrase back in July, 2007, I had witnessed the phenomenal health effects of wheat elimination in several hundred patients.

In the nearly two years that have passed since my original post, I have witnessed hundreds more people who have done the same: eliminate pretzels, crackers, breads of all sorts, bagels, pasta, muffins, waffles, pancakes, etc.

If anything, I am convinced now more than ever that wheat is among the most destructive foods in the human diet. At least 70% of people who eliminate wheat from their diet obtain at least one, if not several, substantial health benefits.

Now, if I were trying to sell you something, say, an alternative to wheat, then you should be skeptical. If I tell you that drug or nutritional supplement X is great and you should take it, only to follow it with a sales pitch, you should be skeptical.

What am I selling? Nothing. I gain nothing by telling everyone to avoid wheat. In fact, I wish it wasn't true. Wheat foods taste good. Wheat flour makes great comfort foods. In years past, I spent many hours sitting at the bagel shop reviewing papers over a cup of coffee and a bagel. No longer.

So here, back by popular demand, the original Wheat Belly post:



Wheat Belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

Thank you, Crestor

20. March 2009 William Davis (9)
I'm sure everyone by now has seen the Crestor ads run by drugmaker, AstraZeneca. TV ads, magazine ads, and the Crestor website all echoing the same message:

"While I was busy building my life, something else was busy building in my arteries: dangerous plaque."

While previous drug trials with Mevacor, Pravachol, Zocor, and Lipitor have focused mostly on examining whether the drugs reduced incidence of cardiovascular events, Crestor studies have also focused on effects on atherosclerotic plaque volume. The best example is the ASTEROID trial that demonstrated approximately 7% reduction in plaque volume by intracoronary ultrasound.

So the AstraZeneca decision makers took the leap from cholesterol reduction to plaque reduction.

I'm sure this switch wasn't taken lightly, but was the topic of discussion at many meetings before the decision to make plaque reduction the focus of hundreds of millions of dollars of advertising. After all, billions of dollars are at stake in this bloated statin market.

Ordinarily, I couldn't care less about how the drug manufacturers conduct their advertising campaigns. But this one I paid attention to because the Crestor ads are helping fuel a new way of thinking about coronary heart disease: It's not about the cholesterol; it's about the atherosclerotic plaque that accumulates in arteries.

It's not cholesterol that grows, limits coronary blood flow, and causes angina. It's not cholesterol that "ruptures" its internal contents to the surface within the interior of the blood vessel and causes blood clot and heart attack. It's not cholesterol that fragments from the carotid arteries and showers debris to the brain, causing stroke. It's all plaque.

I took the same leap years ago, though not backed by hundreds of millions of dollars of marketing money. When I first called my book Track Your Plaque, some of the feedback I got from editors included comments like "I thought this was a book about teeth!" Even now, the word "plaque" in the book title and website is responsible for confusion.

But AstraZeneca is helping me clear up the confusion. As the word plaque gains hold in public consciousness, it will become increasingly clear that cholesterol reduction is not what we're after. We are looking for reduction of plaque.

If you are trying to develop an effective means to reduce or reverse coronary heart disease, then there are two simple equations to keep in mind:


Plaque = coronary heart disease

Cholesterol ? coronary heart disease


Plaque is the disease, cholesterol is not. Cholesterol is simply a crude risk for plaque.

While I'm no friend to the drug industry nor to AstraZeneca, some good will come of their efforts.

Supermarkets and buggy whips

17. March 2009 William Davis (17)
Will supermarkets eventually phase out, joining the history books as a phenomenon of the past? Or are supermarkets here to stay, an emblem of the industrialization of our food--easy access to foods that are convenient, suit the undiscriminating masses, stripped of nutritional value despite the prominent health claim on the package front?

Anna left an insightful comment on the last Heart Scan Blog post, Sterols should be outlawed, along with some useful advice on how to avoid this trap for poor health called a supermarket:


I rarely shop in regular supermarkets anymore (farm subscription for veggies, meat bought in bulk for the freezer, eggs from a local individual, fish from a fish market, freshly roasted coffee from a local coffee place, etc.). What little else I need comes from quirky Trader Joe's (dark chocolate!), the fish market, farmer's markets, a small natural foods store, or mail order.

When I do need to go into one of the many huge supermarkets near me, not being a regular shopper there, I never know where anything is, so I have to ramble a bit around the aisles before I find what I'm looking for (and I almost always can grab a hand basket, instead of a trolley cart).

It's almost like being on another planet! There's always so many new products (most of them I hesitate to even call food). It's really a shock to the senses now to see how much stuff supermarkets sell that I wouldn't even pick up to read the label, let alone put in a cart or want to taste. I'm not even tempted by 99% of the tasting samples handed out by the sweet senior ladies in at Costco anymore (only thing I remember tasting at Costco in at least 6 mos was the Kerrygold Irish cheese, because I know their cows have pasture access and it's real food).

What's really shocking to me is how large some sections of the markets have become in recent years. While Americans got larger, so did some sections of the supermarket (hint - good idea to limit the consumption of products from those areas). Meat and seafood counters have shrunk, though. Produce areas seem to be about the same size as always (but more of it is pre-prepped and RTE in packaging.

But the chilled juice section is h-u-g-e! And no, I don't think there is a Florida orange grove behind the cases. Come on, how much juice do people need? Juice glasses used to be teeny tiny, for a good reason. To me it looks like a long wall stocked full of sugar water. Avoiding that section will put a nice dent in the grocery expenses.

The yogurt case is also e-n-o-r-m-o-u-s! Your 115 yo Bulgarian "grandmother" wouldn't know what to make of all these "pseudo-yogurts"! Chock full of every possible variety, but very little fit to eat. The only yogurts I'll look at are made with plain whole milk, without added gums, emulsifiers, or non-fat milk solids, and live cultures (I mostly buy yogurt now and then to refresh my starter culture at home). I can flavor them at home if needed. The sterols are showing up in processed yogurts, too, along with patented new strains of probiotic cultures (I'll stick to my old fashioned, but time-proven homemade lacto-cultured veggies and yogurt instead).

I found the same "cooler spread" in the butter & "spread" section. The spread options were just grotesque sounding. Actually, the butter options weren't much better, as many were blended with other ingredients to increase spreadability, reduce calories or cholesterol/saturated fat, etc. A few plain butters were enhanced with "butter flavor" - say what? And on no package could it be determined if the butter came from cows that were naturally fed on pasture or on grain in confined pens.


Well said, Anna.

There's a huge supermarket about 1 mile away from my house similar to the one Anna describes with aisle after aisle of eye-catching cellophane-wrapped foods. I go there about every 3 or 4 months, and then I only go to get something I need in a pinch. Every time I go, I too am reminded just how many products there are that look more like junk food than real food.

But there's no real money in real food. Who gets rich off of selling green peppers, tomatoes, and eggs?

Supermarkets sell these modern industrial foods because people buy it: Look around you. You don't get to be a 250 lb 5 ft 2 inch-woman by eating too many cucumbers.

Like Anna, I drive an additional several miles to Trader Joes', buy at farmers' markets whenever possible, buy some odds and ends like wine and cheese and raw nuts at specialty stores. I grow my own basil in a big pot I keep in the kitchen and we are just about to start turning over the soil in the back yard for our vegetable garden. I don't need nor do I miss having the choice among 40 different chips, 25 brands of ready-made microwavable dinners, an entire aisle of breakfast cereasl (all of which are virtually the same with different names and labels), or 75 varieties of salad dressing.

The supermarket for me--and I hope for many of you--has become a place rarely frequented, and only for the odd forgotten item. Oh, I forgot the dog chewies the grocery does have--my dogs love them. So perhaps they are good for something after all.

Sterols should be outlawed

14. March 2009 William Davis (10)
While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.


Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.




Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.




The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












HeartWise orange juice contains 1000 mg sterols per 8 oz serving.













Promise SuperShots contains 400 mg sterols per container.














Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.














MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.














Kardea olive oil has 500 mg sterols per 14 gram serving.










WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.

Texas state representative, Rene Oliveira, has introduced legislation that mandates heart scans for adults in the state of Texas.

Rep. Oliveira

A press release from the SHAPE Society ( Society for Heart Attack Prevention and Eradication) reads:

Assessment of heart attack risk on the basis of traditional risk factors alone such as high cholesterol and high blood pressure and so forth, while useful, misses many who are at high risk and also incorrectly flags some for high risk who are in fact at very low risk of near term heart attack; on the other hand detection of atherosclerosis by non-invasive imaging, as suggested by the SHAPE group, accurately identifies plaque and improves the ability to identify at-risk individuals who could benefit from aggressive preventive intervention while sparing low-risk subjects from unnecessary aggressive medical therapy," said Dr. P.K. Shah, Director of Cardiology at Cedars Sinai Heart Institute in Los Angeles, a leading member of the SHAPE Task Force who is also an active member of the American Heart Association. "Sadly, these vulnerable patients go undetected until struck by a heart attack, because insurance companies don't cover the newer heart attack screening imaging tests."


Rep. Oliveira, whose coronary disease was first uncovered by a heart scan and prompted a bypass operation, states:

"It is about time that we cover preventive screening for the number one killer in Texas, and take action to reduce healthcare costs through preventive healthcare. Right now, we are extending the lives of those who can afford the procedure while hundreds of thousands of Texans with hidden heart disease go undetected because of antiquated thinking. The time has come for this change."


Is this what we've come to? Since practicing physicians are either so entranced by the drug and procedural solutions to heart disease, do we need to resort to heart scan by legislation?

It does indeed appear that we've come to this point. Should this trend catch on, it will surely mean an upfront increase in healthcare costs to cover the expense of heart scans. But in the long run, it will mean reduction in healthcare costs--dramatic reduction--if heart scans prompt effective preventive action.
