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.

Many people, upon first learning of their CT heart scan score, feel like they're on the edge of a sharp drop. It can feel like you're facing a vast, unknown abyss. At the bottom, all those dreaded things that can happen to you: heart attack, heart failure, hospitals, even dying.

I've encountered this "deer in the headlights" look many times. It truly can be frightening to hear that your heart scan score is 300, or 500, or whatever.

What I find truly frightening, however, is when your score prompts the usual array of misinformation commonly dispensed by physicians: "That's so bad you need a heart catheterization", "Nobody knows why people get calcified plaque", or "Reversal is impossible". All absolute bunk.

Let your fear motivate you to do something about your risk for heart disease. Aim for reversal of your coronary plaque and seek out the tools to achieve this. It is possible and, in fact, we do it all the time. I can't claim 100% success, but the majority of people who engage in an effort like the Track Your Plaque program to reverse coronary plaque succeed. Even a substantial slowing of plaque growth from the expected 30% per year is better than submitting to the conventional approach.

At the very least, get both LDL and HDL cholesterol around 60 mg/dl. This alone is a major plus in reducing the risks associated with your heart scan score. It doesn't guaranteee reversal, but it sure tips the odds in your favor.

Organic Rice Krispies?

13. 十月 2006 William Davis (0)


Breakfast cereal manufacturing giant, Kelloggs, is launching a line of three cereals that will carry the "organic" designation: Organic Rice Krispies, Organic Raisin Bran, and Organic Frosted Mini-Wheats.

This reminds me of the advertisements I've seen for "fresh fried chicken", or "fresh from the can", or "contains only pure cane sugar". How about organic tobacco? Would that make cigarettes healthier?

The TV ad ends with the slogan "Childood is calling!" Oh, those marketers are a shrewd, clever bunch. I worry that they're so clever that most people will fall for these ludicrous tricks.

Don't fall for these thinly-shrouded marketing shenanigans. Organic? Who cares. These foods remain unhealthy whether or not they contain pesticide residues. Take a look at the nutritional composition: Rice Krispies, organic or not, is sugar to your body. It is the sort of food that creates pre-diabetes, diabetes, makes us fat, and fans the flames of lipoprotein patterns like small LDL, VLDL, and postprandial particles, all of which is like throwing cow manure on the weed patch of your coronary plaque.

Nuts as functional foods

13. 十月 2006 William Davis (0)
Food manufacturers gave nuts a bad name when they started adding evil ingredients to them. "Party mix", "honey-roasted", mixed nuts, etc., are made with added hydrogenated oils, salt, sugar, excessive quantities of raisins, or other added ingredients that turned a healthy food--nuts--into something that made us fat and hypertensive, raised LDL, dropped HDL, and raised blood pressure.

But nuts themselves are, for the most part, very healthy foods. The very best are nuts with a brown fiber coating like almonds, walnuts, and pecans. Nearly all nuts also come rich in monounsaturated oils similar to that in olive oil. Although calorie-dense, nuts tend to be very filling and slash your appetite for other foods. I have never seen anyone gain weight by adding raw nuts to their diet. In fact, I find adding raw nuts cuts craving for sweets.

Nuts are also among the most concentrated sources of magnesium, containing around 150 mg per 1/2 cup serving. As most Americans are at least marginally if not severely deficient in magnesium, this really helps. Magnesium deficiency is a prominent aspect of "metabolic syndrome" and resistance to insulin.




Some nuts have added benefits like the l-arginine content of almonds or the linolenic acid content of walnuts. However, I think the real health "punch" comes from the fiber and monounsaturate content.

Add 1/4-1/2 cup of raw almonds, walnuts, or pecans per day to your diet and what can you expect? The effects that I see every day that are relevant to plaque control/heart scan score-reducing efforts include:

--Reduction in LDL--usually a 20 mg/dl drop, sometimes more.

--Reduction in triglycerides, especially if nuts replace processed carbohydrate calories. This may be because the fiber and monounsaturate content of nuts reduces blood sugar and the effective glycemic index of any accompanying foods.

--Modest blood pressure reduction.

--Though somewhat inconsistent, partial suppression of the dreaded small LDL particle pattern. We struggle with turning off the small LDL pattern in some people, and raw nuts can provide a real advantage.

If that isn't enough, the fiber content also makes your bowels regular.

Unless there's some reason to avoid nuts (e.g., allergy), nuts should be a part of your heart scan score reducing program. Shop around, as prices can vary wildly. I've been paying $12.99 for a 3 lb bag of raw almonds from Sam's Club, though I've seen almonds elsewhere for up to $12.99 per pound.

For additional commentary, go to one of my favorite Blogs, http://fanaticcook.blogspot.com. The Fanatic Cook's recent post, The Season for Walnuts , provides additional discussion on walnuts and the recent study showing how they improve "endothelial function". The nutritionist behind this Blog has fabulous insights into food, including the concept of "functional foods", i.e., using foods as a treatment tool. She is also unfailingly entertaining.

Can you tell the difference?

12. 十月 2006 William Davis (0)
Stan is 55 years old. He feels fine, is in moderately good physical condition. His LDL cholesterol is 135 mg/dl, HDL 43 mg/dl, triglycerides 167 mg/dl, total cholesterol 211 mg/dl.

Can you tell me whether Stan has heart disease or not?

How about Charles? Charles has an LDL cholesterol of 127 mg/dl, HDL of 44 mg/dl, triglycerides of 98 mg/dl, and total cholesterol of 191 mg/dl. He is also reasonably fit and feels fine. Can you tell whether Charles has heart disease?

If you can't, don't feel bad. Neither can your doctor. But this is the folly of using cholesterol for risk prediction.

Stan's heart scan score: 0

Charles' heart scan score: 978

Look even more closely at Stan's and Charles' cholesterol numbers. Is there some fine distinction we overlooked? What if we calculated total cholesterol to HDL ratio? Or LDL/HDL ratio?

No matter how you squeeze it, shake it, beat it with a stick, you simply cannot use cholesterol numbers to predict heart disease in specific individuals. Yes, the higher your LDL cholesterol and lower your HDL, the higehr your total cholesterol to HDL ratio, the greater the likelihood of heart disease. But you can simply cannot tell in a specific individual at a specific point in time. If you've seen your doctor puzzle over the numbers, understand that he/she is trying to make sense out of something that doesn't make sense, no matter how hard he/she tries.

You simply need to measure the disease itself: get a CT heart scan, the only measure of atherosclerotic coronary plaque that you have access to.

By the way, if you haven't seen it yet, go to the Track Your Plaque website (www.cureality.com) to see the news piece reporting the American Heart Association's much overdue position statement on CT heart scanning. The AHA has finally released a statement which, in effect, provides their "official" endorsement. Blocked by political shenanigans behind the scenes for several years, the guidelines finally made it to press. The only real difference it makes to me is that my patients may finally get their heart scans paid for by insurance, once the insurance companies realize that it's getting tougher and tougher to dodge their responsibility.

Statin agents and muscle aches

11. 十月 2006 William Davis (2)
How common are muscle aches with the statin drugs?

It depends on who you ask. If you ask the drug manufacturers, they will tell you no more than 2% of people who take them. They back this up with the experience in tens of thousands of people in published clinical trials.

What if we ask people who take them outside of clinical trials. How many then? I estimate, from my large experience, over 80%! In other words, muscle aches are inevitable in nearly everyone who takes them. The longer you take them, the higher your dose, the more likely muscle aches are going to be.

Why the disconnect between published data and real-world experience? I really don't know. In some instances, the differences are dramatic. The ASTEROID trial, for instance, in which Crestor, 40 mg, was given for two years, only resulted in 8% of people dropping out because of side-effects. My experience: everybody--nobody can tolerate this dose for any length of time.

Let me qualify what "muscle aches" mean. It means achiness and/or weakness, usually mild, occasionally moderate to severe, worse upon awakening and less with use. It can affect many muscles or it can involve only one. Rarely is it incapacitating but it is commonly annoying and frightening. It commonly shows up as gradually diminishing strength with exercise. Strength usually returns promptly upon stopping the offending drug.

"Rhabdomyolysis", or true muscle destruction is, fortunately, very unusual in otherwise well people. People with abnormal kidney function, diabetes, and other concurrent illnesses are somewhat more prone. But in reality, rhabdomyolysis is unusual. I've personally seen it twice, both in people sick for other reasons.

Coenzyme Q10 (CoQ10) supplementation has been a godsend for us. At least 4 out of 5 people who require statins and develop muscle aches respond favorably, but it requires 100 mg per day. The preparation must be oil-based to work, not powder in a capsule which exerts no effect. Some people get by with less; some require as much as 300 mg per day. I've had favorable experiences with the CoQ10 from Sam's Club, GNC, Vitamin Shoppe, and Life Extension (www.LEF.org).

The Track Your Plaque target for LDL cholesterol is 60 mg/dl. Many people do indeed use statins to achieve this level, the level of LDL that amplifies your chances of heart disease reversal, i.e., reduction of heart scan score. The only drawback that I'm aware of with CoQ10 replacement is cost. Beyond this, it's a benign supplement that even supplies higher energy for some people who take it.

More catheterizations would make me happy!

I received this fax today from a cardiologist seeking a position:

"I would prefer to perform as many interventions [stents, angioplasties, etc.] as possible..."

That about sums it up, doesn't it? The goal of this young man, trained in major universities including Columbia University, Harvard, and Emory, is not to pursue an avenue of investigation or healthcare that yields real answers. His goal is to perform as many procedures as possible.

This attitude is deeply ingrained in cardiologists. It's also shared by all procedural medical specialties: the drive to do more and more procedures. It's not because it does more good for the public, but it fulfills a primitive impulse to spread your influence, enlarge your territory, and--of course--make more money.

Personally, I find this impulse repulsive. The fact that this young cardiologist looking for a position is willing to make this statement out in the open demonstrates how widely accepted this attitude is. Imagine your cancer surgeon, looking for a new job, said, "I'm looking to remove as many tumors as I can."

My colleagues have lost sight of the fact that we're trying to reduce or eliminate disease, not enrich our pockets or service some primitive impulse to beat others at our game.

"I hate fish oil!"

9. 十月 2006 William Davis (1)
I get this comment occasionally, usually from the fishy belching that can occur, rarely because of other crazy effects like rash, fishy body odor, etc.

In the vast majority, fish oil is a benign but wonderfully effective agent. Track Your Plaque followers know that fish oil, starting at 4000 mg per day of a standard 1000 mg capsule preparation, dramatically reduces triglycerides and thereby raises HDL, partially suppresses small LDL, and is the best agent available for reducing postprandial (after eating) abnormalities like IDL and certain VLDL fractions.

However, an occasional person (about 1 in 20) just doesn't like the effects. Are there alternatives? Fish oil packs such a wallop of beneficial effects that can not be replaced by any other single agent or lifestyle practice. For this reason, we have a number of easy strategies to enhance your tolerance for fish oil. (Of course, if your and/or you doctor determine that you're allergic to fish oil, then you should indeed avoid it; thankfully, this is rare.)

Helpful strategies include:

--Refrigerate fish oil capsules--this cuts back on fish belching.
--Take only with meals. This also may increase fish oil's benefits on suppressing after-eating lipoprotein abnormalities.
--Take an enteric-coated preparation--this delays breakdown of the tablet/capsule, making fishy belching less of an issue. Sam's Club has an inexpensive preparation.
--Take liquid fish oil. Usually orange or lemon flavored, liquid fish oil may be a faint fishy taste and odor, but usually not as prominent as the capsules. There's also less stomach upset.
--Coromega--a paste form of fish oil available at health food stores or through http://www.coromega.com. Coromega tastes fruity and comes in little squeeze envelopes.
--Frutol--Pharmax, a British company, makes another fruity fish oil that is non-oily and tastes like apricot. It's actually fairly reasonably priced, too. However, it is hard to find. The only way I know to get is to go online at www.pharmaxllc.com. You may have to actually order through a health care provider.

When using any preparation of fish oil, the best way to determine your dose is to add up the EPA and DHA content. For instance, if you use a fish oil liquid that contains 320 mg EPA and 240 mg DHA per teaspoon, you will need two teaspoons a day to achieve the equivalent of our starting dose of 1200 mg of EPA+DHA, usually provided by 4000 mg total in 4 capsules. Note that some lipid and lipoprotein disorders will require higher doses, e.g., 1800 mg EPA+DHA for high triglycerides (>200 mg/dl) or high IDL.

Sudden death in athletes

6. 十月 2006 William Davis (0)
A recent report in the Journal of the American Medical Association details how a group in the Veneto region of Italy cut back on the incidence of sudden cardiac death in athletes by a simple screening program.



You can read the abstract of the article at http://jama.ama-assn.org/cgi/content/full/296/13/1593.

Although sudden death in athletes is still a rare event, it is especially tragic when it happens. In this population, the incidence was 3.6 deaths per 100,000 athletes aged 12 to 35 years. By implementing a simple screening program that involved only a physical examination and an EKG, an astounding 89% reduction in sudden death was documented.

What lessons does this hold for those of us interested in coronary plaque reversal? Beyond the obvious lesson of pointing out the great benefit of simple screening of athletes, I believe that it tells us the value of simple screening tools for heart disease in general. It is my strong belief that, if we were to implement CT heart scans among the broad population of men 40 years and over, women 50 years and over--without regard to cholesterol or other relatively lame risk identifiers--we could slash the risk for heart attack and death 90% or more. Putting CT heart scans into the hands of the public makes your coronary risk obvious. It takes the guesswork out of risk predictors like cholesterol and high blood pressure.

But heart scans are already available, you say! Yes, of course they are. But the lack of insurance reimbursement continues to be a restricting factor for many people, despite the number of lives that could be potentially saved and the money that would be saved in the long run by reducing need for major heart procedures. The continuing resistance to prevention by my cardiology colleagues and the persistent ignorance of primary care physicians also remain major impediments.

But it's getting better. You don't have to be chained by ignorance. Put your CT heart scan to good use.

My heart scan was wrong!

6. 十月 2006 William Davis (0)


Tom came into the office ready for a confrontation.

Tom's wife insisted that he see me to discuss the implications of his CT heart scan score of 459. At age 50, this was clearly bad news that placed Tom in the 99th percentile (worst 1% of men in his age group).

But Tom had already undergone a stress test. There had apparently been a small abnormality, and a heart catheterization had been performed by another cardiologist. "They told me they didn't need to do anything. No stent, no ballon, no bypass, nothing!"

I asked, "Did they tell you that there was any plaque or blockages seen?"

"Yeah, but he said it was nothing. So the heart scan was wrong!"

I've been here many times before. I explained to Tom that, no, his heart scan was not wrong. All the tests he'd undergone siimply provided a different perspective on the same disease. You could say:

--The stress test, being a test of blood flow, may have been abnormal because of the abnormal constrictive behavior of arteries containing plaque, known as "endothelial dysfunction", because the inner lining of arteries (the endothelium) control the tone of the artery. Abnormal constriction in arteries with plaque is quite common.

--The catheterization simply showed that no plaque had collected in a configuration to block flow, thus no stent, etc., since flow was normal. But there was indeed plaque.

All three tests were right; none were wrong. They all provided a little different perspective on the same process. Of course, I favor the heart scan as the means to identify, precisely measure, and track the atherosclerotic plaque in your arteries. The stress test is too crude and only measures flow, the catheterization is not something you'd want to undergo year after year. Catheterization also is too crude a measure to precisely track plaque growth or reversal.

So I explained to Tom that, even though a stent or similar procedure was unnecessary, he remained at substantial risk for heart attack due to plaque "rupture". In fact, Tom's heart attack risk was 5% per year, or approximately 50% over the next decade. That is, indeed, substantial. In fact, you might say that, of the three tests Tom underwent, only the heart scan revealed his true risk.
