Addictive Foods

25. June 2007 William Davis (3)
Kraft Foods, Inc. is manufacturer of Kool Aid, Oscar Mayer, Kraft Macaroni and Cheese, Velveeta, Honey Maid Grahams, and hundreds of other processed food products. Post cereals also falls under the umbrella of Kraft with products like Raisin Bran, Post Toasties, and Fruity Pebbles. Annual revenues in 2006 for Kraft: $34.4 billion. A big operation with enormous influence over our eating habits.

Nabisco is manufacturer of Oreos, Ritz Crackers, Chips Ahoy and many others. Like Kraft/Post, it is also a big player.

While Nabisco was owned for several years by tobacco giant RJ Reynolds, in 2000 it was acquired by Philip Morris, another big tobacco manufacturer.

More recently in Spring, 2007, Philip Morris (now called Altria--you'd change your name, too, if it was synonymous with dirt) spun off its Kraft subsidiary for a big profit. However, the management structures remain intertwined.

In other words, despite the shuffling of shares, the two industries, big tobacco and big food, are in many respects one and the same.

Is it any surprise that the same industry that made billions of dollars pushing addictive nicotine products responsible for the deaths of hundreds of thousands of people is now intimately involved with addictive products produced and marketed by the processed food industry?

If you believe that food manufacturers are innocently and honestly conducting their businesses, simply think back to the testimony provided in front of Congress during the tobacco industry hearings. Broad deception, concealed truths, and outright lies were commonplace. There was no conscience involved. This was about money--and lots of it.

Why should the processed food industry, intimate with the tobacco industry, be any different?

If you want control over heart disease and your heart scan score, buy produce and buy local. Spend your time in the produce aisle, not the cereal or chip aisle. Unprocessed food, unadorned by bright labels, cartoon animals, American Heart Association endorsements, that's what we should seek.

Heart Scan Curiosities #7

25. June 2007 William Davis (1)



Here's a situation that crops up once in a while, occurring in perhaps 2% of heart scans.

The white within the circled area represents calcium, and thereby atherosclerotic plaque, situated immediately at the "mouth", or opening, of the the right coronary artery. What is somewhat unusual is that this plaque is not principally coronary, but aortic. That is, the plaque is mostly situated in the large vessel called the aorta. The three coronary arteries arise from the aorta.

In this instance, the aortic plaque involves the mouth of the right coronary artery. (In views not shown, the plaque also extends into the artery as well.) I call this a "double whammy" because the same plaque can post risk for heart attack and stroke.

Generally, aortic plaques pose risk for stroke. When aortic plaque fragments, little bits and pieces can travel upward to the brain and block an artery, thus a stroke.

In the coronaries, disrupted ("ruptured") plaques don't generally shower debris, but permit blood clot formation, resulting in heart attack.

This plaque, however, poses the theoretical risk of both heart attack and stroke because of its strategic location.

Should a plaque like this be handled any differently? I don't think so. But it does provide another reason to take atherosclerotic plaque in any artery seriously.

The nutrition counterculture

23. June 2007 William Davis (2)
When we look back over our American nutritional history over the last 50 years, it's hard not to come to the conclusion that much of the innovation in nutrition did not come from official agencies like the Food and Nutrition Board of the Institute of Medicine, the National Academy of Sciences, the FDA, the USDA, or the AMA.

Instead, it came from the popular culture. It came from bold, extravagant claims made by maverick figures like Ancel Keys, Nathan Pritikin, Dean Ornish, and Robert Atkins. Of course, some ideas have now fallen by the wayside, dismissed in a broad American "experiment" as ineffective, impractical, or kooky. But it permitted experimentation on an extraordinary scale with millions of people following a particular strategy at a time.

The advice of the official agencies tended to be reactionary. When nutritional deficiencies (remember those?) of the early 1900s were prevalent, they issued advice on food choices to help alleviate deficiencies. When deficiency transformed into excess after World War II, "smart" food choices from food groups and "sensible eating" became the theme.

Unfortunately, the advice was always adulterated by the enormous influence of various special interests, anxious to protect their national franchise. Powerful groups like the meat industry, wheat producers, and the dairy industry all made sure they had a big hand in crafting and influencing what was told to the American people.

The result: the advice offered by official groups has always represented the compromise of what some agency wished to convey to the people and the very powerful input of industry. What if the government decided to advise us what automobile to buy? Imagine the uproar in the auto industry when Washington tells us to buy Toyota for fuel economy and reliability. How long would that advice last?

That's why almost no knowledgeable adult follows the advice of the USDA, the National Academy of Sciences, or the Food Pyramid. I believe that we all intuitively recognize that the advice is watered-down, sometimes silly, sometimes downright unhealthy.

Nonetheless, the national experiment in diet that has taken place since 1950 has led to a collective wisdom of what is good and what is bad. The most productive conversations on nutrition therefore take place outside of the USDA and Washington. It occurs, instead, in places like bookstores, websites, and the media. Of course, there's lots of misinformation and profiteering in these sectors, as well. But like the enormous force unleashed by the collective wisdom of those contributing to the Wikipedia phemonenon, we've zig-zagged to something closer to the truth than ever uttered by an official agency.

Prescription vitamin D

23. June 2007 William Davis (32)
Niacin:

Over-the-counter: $2-5 per month
Prescription: $120 per month


Fish oil:

Over-the-counter: $3-6 per month
Prescription: $120 per month


Vitamin D:

Over-the-counter: $2 per month
Prescription: $70 per month



With vitamin D in particular, the prescription form is vastly inferior to the over-the-counter preparation. This is because the prescription form is ergocalciferol, or vitamin D2, not the effective human form, vitamin D3 or cholecalciferol.

When you're exposed to sun, what form of vitamin D is activated in the skin? It's all vitamin D3, no vitamin D2 whatsoever. Vitamin D3 is also far more effective than D2. People taking D3 (as long as it's oil-based) easily obtain healthy levels of vitamin D in the blood. People taking 50,000 units per day of D2 (the recommended quantity) remain miserably deficient, with minor increases in vitamin D blood levels. In short, D2 barely works at all. D3 works easily and effectively.

Moreover, D2 is the plant-based form. It is a form not found naturally in humans. D3 is the mammalian form, the same found in humans that exerts all its biologic benefits.

Then why is the prescription form of vitamin D2 (brand names Driscol and Calciferol) more expensive?

It's the same old pharmaceutical industry scam: Look for something patent protectable, regardless of whether it's superior to the non-patent protectable product, then sell it for exagerated profits. Though it is inferior and the science and clinical experience prove that it's inferior, you can still fool lots of people, including prescribing physicians. So what if you only make $50 or $100 million?

Don't fall for it. Prescription doesn't necessarily mean superior. In fact, the prescription form may be significantly inferior, as with vitamin D2. But the pharmaceutical industry carries such power and persuasion, who's going to know?

Nutrition activist Mike Adams

20. June 2007 William Davis (1)












I borrowed the above comic from the website of nutritionist, more properly nutrition activist and author, Mike Adams. His website, www.newstarget.com, was a pleasant surprise.

I was actually looking for some thoughts on pharmaceutical advertising and its pervasive and destructive effects and came across one of Adam's reports, Pharmaceutical television advertising is a grand hoax at http://www.newstarget.com/021526.html. The piece is a rant against the pharmaceutical industry's constant bombardment of the media, who have also been co-opted into their service, enticed by the enormous advertising revenues the drug industry brings.

But I was surprised to find an insightful, informative website on health issues, particularly healthy eating that rejects the manufactured food industry's intensive effort to persuade us to eat their products. While I don't agree with everything Adams has to say, his website provides some great food for thought. He also provides lots of downloadable information.

There's also some great laughs at his poke at the pharmaceutical industry with his Disease Mongering Engine at http://www.newstarget.com/disease-mongering-engine.asp, in which you get to create your own diseases. I got a real kick out of this.

CT scans and radiation exposure

19. June 2007 William Davis (8)


The NY Times ran an article called

With Rise in Radiation Exposure, Experts Urge Caution on Tests at

http://www.nytimes.com/2007/06/19/health/19cons.html?_r=1&adxnnl=1&oref=slogin&adxnnlx=1182254102-vQpytpx6W/Z9gvAaNPDZvA



“This is an absolutely sentinel event, a wake-up call,” said Dr. Fred A. Mettler Jr., principal investigator for the study, by the National Council on Radiation Protection. “Medical exposure now dwarfs that of all other sources.”


Where do CT heart scans fall?

Let's first take a look at exposure measured for different sorts of tests:



Typical effective radiation dose values

Computed tomography Milliseverts (mSv)

Head CT 1 – 2 mSv
Pelvis CT 3 – 4 mSv
Chest CT 5 – 7 mSv
Abdomen CT 5 – 7 mSv
Abdomen/pelvis CT 8 – 11 mSv
Coronary CT angiography 5 – 12 mSv

Non-CT Milliseverts (mSv)

Hand radiograph Less than 0.1 mSv
Chest radiograph Less than 0.1 mSv
Mammogram 0.3 – 0.6 mSv
Barium enema exam 3 – 6 mSv
Coronary angiogram 5 – 10 mSv
Sestamibi myocardial perfusion (per injection) 6 – 9 mSv
Thallium myocardial perfusion (per injection) 26 – 35 mSv

Source: Cynthia H. McCullough, Ph.D., Mayo Clinic, Rochester, MN


If you have a heart scan on an EBT device, then your exposure is 0.5-0.6 mSv, roughly the same as a mammogram or several standard chest x-rays.

A heart scan on a 16- or 64-slice multidetector device, your exposure is around 1.0-2.0 mSv, about the same as 2-3 mammograms, though dose can vary with this technology depending on how it is performed (gated to the EKG, device settings, etc.)

CT coronary angiography presents a different story. This is where radiation really escalates and puts the radiation exposure issue in the spotlight. As Dr. Cynthia McCullough's chart shows above, the radiation exposure with CT coronary angiograms is 5-12 mSv, the equivalent of 100 chest x-rays or 20 mammograms. Now that's a problem.

The exposure is about the same for a pelvic or abdominal CT. The problem is that some centers are using CT coronary angiograms as screening procedures and even advocating their use annually. This is where the alarm needs to be sounded. These tests, as wonderful as the information and image quality can be, are not screening tests. Just like a pelvic CT, they are diagnostic tests done for legimate medical questions. They are not screening tests to be applied broadly and used year after year.

Always be mindful of your radiation exposure, as the NY Times article rightly advises. However, don't be so frightened that you are kept from obtaining truly useful information from, for instance, a CT heart scan (not angiography) at a modest radiation cost.



Detail on radiation exposure with CT coronary angiograms on multidetector devices can be found at Hausleiter J, Meyer T, Hadamitzyky M et al. Radiation Dose Estimates From Cardiac Multislice Computed Tomography in Daily Practice: Impact of Different Scanning Protocols on Effective Dose Estimates. Circulation 2006;113:1305-1310, one of several studies on this issue.

Mediterranean diet vs. American Heart Association Diet

18. June 2007 William Davis (4)
In 1994, the Lyon Heart Study demonstrated a 50-70% reduction in coronary events in participants who followed a diet rich in vegetables, olive oil, fish, nuts, red wine, and enjoyed meals as a family activity. Various other studies have documented similar phenomena with less metabolic syndrome, better lipid patterns, less obesity with the Mediterranean lifestyle.

There are two fundamental differences between the Mediterranean diet and the diet advocated by the American Heart Association (AHA) for people with heart disease: the Mediterranean diet uses olive oil more liberally, such that fat calories can reach 40% of total; and, unlike the AHA diet, processed foods are not a part of the Mediterranean diet. Greeks, for instance, are far less likely to eat Count Chocula cereal for breakfast, or snack on Healthy Choice Premium Caramel Swirl Sandwich (ice cream sandwiches) or Malt-O-Meal Honey Nut Scooters. All three of these foods on listed on the AHA Heart-Check Mark heart-healthy program.

In other words, remove all the processed foods, and the AHA diet pretty closely resembles the Mediterranean diet. There are differences but they tend to be relatively small. If the only major difference is the presence of processed foods, wouldn't you therefore expect the AHA to embrace the Mediterranean diet?

Here's what their official stand on the Mediterranean diet states:

Does a Mediterranean-style diet follow American Heart Association dietary recommendations?

Mediterranean-style diets are often close to our dietary recommendations, but they don’t follow them exactly. In general, the diets of Mediterranean peoples contain a relatively high percentage of calories from fat. This is thought to contribute to the increasing obesity in these countries, which is becoming a concern.



The AHA is actually lukewarm towards the diet that was the first to show a dramatic decrease in heart attack and death. Why?

The answer is obvious, once cast in this light. To wholeheartedly endorse the Mediterranean diet might be seen as an indirect rejection of American processed foods. You know, the foods that have caused an extraordinary and unprecedented epidemic of obesity in the U.S., the foods that are manufactured by ConAgra, General Mills, Kelloggs--all also major financial contributors to the AHA, according to the AHA Annual Report.

I tell my patients: If you want heart disease, follow the American Heart Association diet. In my view, it is a diet founded on politics and money, not on health. How else could Cocoa Puffs be regarded as heart healthy?

Track Your Plaque in 50,000 BC

16. June 2007 William Davis (3)
Imagine we could send you back in a time machine to 50,000 BC.

However, our agreement: no modern tools or equipment. Just your brain, hands, and legs. And your landing spot will be tropical or semi-tropical, the same climate that humans spent much of their evolutionary time in.

Not only might you rub elbows with contemporaries like homo erectus and neanderthalensis, you'd also have to fend for your life and survival.

To eat, you will have to chase and kill wild game, all with your bare hands or crude tools crafted from sticks and stones. You will have to learn what wild berries, roots, and plants are edible and distingusih them from those that make you retch, make your bowels run, or kill you. You won't be able to cultivate grain, at least for a good long time, since you don't have a community that makes such an undertaking easier.

Instead, you are constantly on the run, from the moment you awake until you finally settle back as the sun sets, hopefully with a full stomach, but often empty and growling, anticipating the hunt and forage of tomorrow.

You are outdoors all day, except for the period when you hide in your cave or self-made shelter. You wear what little clothing you can make yourself from your kills, a skin or two. Your skin becomes a dark brown, a 5 foot 10 inch male will weigh 140 lbs, a 5 foot 5 inch woman 95 lbs. There are obvious downsides: your teeth will rot, you will be prone to infections, and predators view you as fair game.

But the result will be that many chronic diseases of modern life will no longer be worries for you. Heart disease? Highly unlikely. Do you need vitamin D? No, because you are outdoors virtually all day with most of your body surface area exposed to sun. Omega-3 fatty acids? You get those from the wild game you eat, since they have higher omega-3 content feeding in the wild, not eating corn like modern livestock. Since your body fat is minimal, just enough for survival, you don't need niacin.

In other words, many of the strategies of the Track Your Plaque program are modern necessities, responses to the "deficiencies" of modern life. Of course, I don't really have a time machine. I also doubt that you wish to hunt wild game every day, forage for plants and roots, run nearly-naked in the sun. You probably also have become accustomed to brushing your teeth and not viewing every animal as a potential threat to your life.

Nonetheless, I find this an interesting exercise for understanding the role of all the tools we use in the Track Your Plaque program for plaque control.

When pessimism wins

15. June 2007 William Davis (3)
When I first met Hank, I immediately sensed it: anger, hostility, fear. His heart scan score of 685 just made it worse.


He didn't want to be there talking to me. His wife was giving him a hard time. Work was a constant source of irritation. The receptionist at the front desk screwed up his paperwork. Our office charges were too much.


In short, Hank was a pessimist. A bad one.


All the nutrition information out there is bunk. Only he knew how he should eat right. It's stupid to take a lot of fish oil. "You want me to grow gills?"


Among the parameters we use in the Track Your Plaque program is blood pressure during exercise, which provides a surrogate measure of blood pressure during emotional stress, anxiety, etc. "No, I don't need that. I already exercise." No amount of justification could change his mind. "A guy at work had a stress test. They said everything was fine, then Bang! He drops dead. What good is that?"


Hank did go along with a few pieces of advice.


A repeat heart scan 12 months after the first: 870, a 27% per year rate of increase. That's about what would happen if Hank had done nothing, had taken no action to try and stop or reduce his heart scan score.


I don't know if Hank will ever succeed in dropping his score. In fact, I suspect that he will fail, meaning that plaque will grow and he will eventually, perhaps in a year, two or three, require several stents, heart bypass, or have a heart attack. In other words, Hank's pessimism is a self-fulfilling phenomenon: If he believes he will fail, he will. If he believes the world is a rotten place, it is.


Is it possible to "cure" someone like Hank of his deeply-rooted pessimistic attitudes? I don't know of any easy solutions for someone with attitudes as deeply-ingrained as Hank's. (See my prior post, "Cure for pessimism?" at http://heartscanblog.blogspot.com/2007_05_01_archive.html.)

I believe it does help to make someone aware of their attitudes and that it does indeed exert ill health-effects--if they will believe it. But this is a very tough nut to crack.

Bad news on CoQ10?

13. June 2007 William Davis (8)
A review of the effects of Coenzyme Q10 (CoQ10) on the muscle aches and weakness (myopathy) of statin drug therapy was just published in the Journal of the American College of Cardiology.

(Marcoff L, Thompson PD. The role of coenzyme Q10 in statin-associated myopathy. J Amer Coll Cardiol 2007;49(23):2231-2237.)

This is not a study, but a review of the existing scientific and clinical data available on this topic. The study authors conclude with a lukewarm statement:

". . .there is insufficient evidence to prove the etiologic [causal] role of CoQ10 deficiency in statin-associated myopathy and that large, well-designed clinical trials are required to address this issue. The routine use of CoQ10 cannot be recommended in statin-treated patients. Nevertheless, there are no known risks to this supplement and there is some anecdotal and preliminary trial evidence of its effectiveness. Consequently, CoQ10 can be tested in patients requiring statin treatment, who develop statin myalgia, and who cannot besatisfactorily treated with other agents. Some patients may respond, if only via placebo effect."

Should the media get hold of this report, be prepared for the usual "Nutritional supplement no help for drug toxicity" headlines, or "Yet another nutritional supplement shows no benefit" with parallels drawn to vitamin C or E.

There are several issue that need to be factored into the discussion:

1) This is not a study, just a review. Thus, any biases of the authors are more likely to exert themselves.

2) The understanding of CoQ10 absorption among different preparations may be an issue. I just received a mailing from Life Extension that made extravagant claims about the superior absorption of ubiquinol, to be distinguished from ubiquinone, the more common form. They claim that eight-fold increased absorption and blood levels of CoQ10 are achievable with ubiquinol. Unfortunately, virtually all the supportive data are unpublished, proprietary observations, i.e., generated by companies who make or sell it. This is as reliable as drug manufacturers who publish glowing reports on their own drugs--perhaps it's true, but it requires unbiased corroboration.

3) Despite the lack of a large, well-funded clinical trial (all are small), the issue continues to live and breathe because of the powerful anecdotal experience.

In our experience, CoQ10 does work. It doesn't work all of the time, perhaps just 80-90% of the time. It does generally require higher doses (100 mg per day, occasionally more). It very clearly must be an oil-based gelcap (just like vitamin D) to work; capsules containing powder do not work.

It's difficult to doubt when someone starts a statin drug, develops the muscle aches and weakness, begins CoQ10 and obtains distinct relief, stops CoQ10 and aches and weakness return, then only to go away again with resumption of CoQ10 . I've seen this countless times.

We do need better information on CoQ10. There's no doubt about it. For people who obtain benefit from statin therapy, I think CoQ10 remains a useful solution. A better solution would be to get rid of the offending drug. But that's not always possible--e.g., LDL cholesterol 190 mg/dl despite the best diet and "adjunctive" food effort. Then CoQ10 can be very useful.

Omega-6 / omega-3 ratio

7. August 2008 William Davis (11)
Most of us already know that the intake of omega-6 fatty acids in the American diet has gone overboard, much at the expense of the omega-3 fraction. This occurred as a result of the misguided advice of the 1970s and 1980s to eat polyunsaturated oils like corn, sunflower, and safflower, because of their presumed cholesterol-reducing properties compared to saturated fats. However, more recent examinations of this advice have suggested that the omega-6 fraction of oils present in polyunsaturated oils may amplify arachidonic acid and other inflammatory patterns despite the reduction in cholesterol (total and LDL).

Dr. Artemis Simopoulos of the Center for Genetics, Nutrition and Health in Washington, D.C. has written extensively on the role of omega-6 and omega-3 fatty acids in diet.

In a review entitled The Importance of the Omega-6/Omega-3 Fatty Acid Ratio in Cadiovacular Disease and Other Chronic Disease , Dr. Simopoulos collects the following comparison of omega-6 to omega-3 ratios from various populations:


Paleolithic humans 0.79
Greece (prior to 1960) 1.00-2.00
Current Japan 4.00
Current India, rural 5-6.1
Current United Kindom and northern Europe 15.00
Current United States 16.74
Current India, urban 38-50

(The numbers refer to the ratio of omega-6 to omega-3 intake.)


If we believe the observations of Dr. Loren Cordain and others, while paleolithic man died of trauma and infectious diseases, they did not die of heart disease. Paleolithic human intake of omega-3 exceeded that of omega-6.

Likewise, the traditionally low cardiac event regions of the world like Japan and Greece have less omega-3 intake than Paleolithic man, but still many times more than the U.S. and U.K.

Worst of all with an enormous preponderance of omega-6 over omega-3 are urban Indians, who experience among the highest rates of heart disease in the world.

Just for perspective, let's assume you eat an 1800 calorie per day diet, of which 30% of calories come from fat. This would amount to 540 calories per day from fat. With 9 calories per gram of fat, this means that there are 60 grams, or 60,000 mg, of fat in your diet per day.

Paleolithic man has been found to have existed on a diet consisting of 21% of calories from fats. Again assuming an 1800 calorie per day diet, that comes to 42 grams of fat per day (42,000 mg).

If we were to try to recreate the Paleolithic fat composition of diet, we would ingest 21,000 mg of omega-3 fatty acids (EPA, DHA, linolenic acid) per day. Even recreating a Japanese experience with a 4:1 ratio, it would mean 8400 mg of omega-3 per day. (Curiously, this does not agree with all estimates of Japanese intake of omega-3s.)

No matter how you look at it, cultures with lower rates of cardiovascular disease take in greater--much greater--quantities of omega-3 fatty acids.

So don't complain about your six fish oil capsules (usually containing 6000 mg of total oil, 1800 mg omega-3s)!

Dr. Bernadine Healy on heart scans

5. August 2008 William Davis (1)

A Heart Scan Blog reader brought the following tidbit to my attention.

Cardiologist and now writer for U.S. News and World Report, Dr. Bernadine Healy, wrote this editorial, a glowing endorsement of heart scans:

The approach is beautifully simple. Calcium accumulates in advanced plaques, so calcium visible in the heart's arteries indicates atherosclerosis. An exploding number of studies in the past few years have unequivocally shown that the calcium score predicts both heart attack and sudden death. As a generalization, patients with scores between 100 and 400 face three to four times the risk of a heart attack or death compared with others at the same age with a zero score. Over 400, that elevated risk more than doubles.

Most doctors rely instead on the Framingham calculator, which estimates a symptom-free person's risk of a heart attack in the next 10 years based on smoking history, blood pressure, cholesterol levels, sex, and age. It's available free online from the National Institutes of Health. Most people taking the test will have minimal or no coronary disease, though risk estimates over 9 percent should inspire vigorous preventive efforts. For some, however, coronary heart disease is sneaky, and Framingham will underestimate what lies ahead. Roughly half of those who suffer a major heart attack or sudden coronary death are symptom free. Calcium scores are additive to Framingham; they pick up the individual surprises by using X-ray vision to look inside the heart. No wonder insurance companies are scrambling to use coronary calcium scores—life insurers, that is.


Dr. Bernadine Healy is no small-time player. In addition to her academic credentials, she is former chief of the National Institutes of Health (the first woman to hold the influential post), former head of the American Red Cross, and former deputy director of the White House Office of Science and Technology Policy under the Reagan administration. An endorsement of CT heart scans, though written under the guise of a probing editorial, will do an enormous amount of good to overcome the hurdles in gaining wider acceptance of heart scans.

Those of us applying heart scans in everyday practice have long appreciated their enormous power to detect and track coronary plaque. Framingham scoring can't even touch the certainty and quantification provided by heart scans in day-to-day life. Hundreds of studies have validated their use, but they still suffer from lying in the shadows of the procedural bullies aiming to boost the number of heart catheterizations, angioplasties, stents, bypass surgeries.

Dr. Healy, a voice with great weight, not just a political figure but also a cardiologist and scientist, has done a great service to broadcast the message of heart scanning.

Mercury and fish oil

2. August 2008 William Davis (9)
As time passes, the dose of fish oil advocated in the Track Your Plaque program is going upward.

While epidemiologic studies, like the Chicago Western Electric Study and the Nurses' Health Study suggest that decreases in mortality from heart disease begin by just eating fish a couple times per month, there are newer data that suggest greater quantities confer greater benefits.

In the last Heart Scan Blog post, I discussed the recently-released ERA JUMP Study that demonstrated a relationship between higher omega-3 fatty acid blood content and reduced quantities of carotid and coronary plaque. The JELIS Study demonstrated a 19% reduction in cardiovascular events when fish-consuming Japanese added 1800 mg of EPA (only).

However, the suggestion that increased quantities of fish oil potentially yield greater protection from heart attack and facilitate coronary plaque regression is also stirring up worries about mercury exposure. So I dug up a Heart Scan Blog post from a year ago that discussed this issue and reprint it here.


I often get questions about the mercury content in fish oil. I've even had patients come to the office saying their primary care doctor told them to stop fish oil to avoid mercury poisoning.

Manufacturers of fish oil also make claims that this product or that ("super-concentrated", "pharmaceutical grade", "purified", etc.) is purer or less contaminated than competitors' products. The manufacturers of the "drug" Omacor [now Lovaza], or prescription fish oil, have added to the confusion by suggesting that their product is the most pure of all, since it is the most concentrated of any fish oil preparation (900 mg EPA+DHA per capsule). They claim that "OMACOR is naturally derived through a unique, patented process that creates a highly concentrated, highly purified prescription medicine. By prescribing OMACOR® (omega-3-acid ethyl esters), a prescription omega-3, your doctor is giving you a concentrated and reliable omega-3. Each OMACOR capsule contains 90% omega-3 acids (84% EPA/DHA*). Nonprescription omega-3 dietary supplements typically contain only 13%-63% EPA/DHA."

How much truth is there in these concerns?

Let's go to the data published by the USDA, FDA, and several independent studies. Let's add to that the independent (and therefore presumably unbiased) analyses provided by Consumer Reports and Consumer Labs (www.consumerlab.com). How much mercury has been found in fish oil supplements?

None.

This is different from the mercury content of whole fish that you eat. Predatory fish that are at the top of the food chain and consume other fish and thereby concentrate organic methyl mercury, the toxic form of mercury. Thus, shark, swordfish, and King mackerel are higher in mercury than sardines, herring, and salmon.

The mercury content of fish oil capsules have little to do with the method of processing and much more with the animal source of oil. Fish oil is generally obtained from sardines, salmon, and cod, all low in mercury. Fish oil capsules are not prepared from swordfish or shark.

Thus, concerns about mercury from fish oil--regardless of brand--are generally unfounded, according to the best information we have. Eating whole fish--now that's another story for another time. But you and I can take our fish oil to reduce triglycerides, VLDL, IDL, small LDL, and heart attack risk without worrying about mercury.


I am not advocating ad libitum eating of fish. Sadly, this may be related to excessive accumulation of contaminants. I am suggesting that greater quantities of omega-3 fatty acids from relatively contaminant- and mercury-free fish oil capsules.

More on this in an upcoming webinar on the Track Your Plaque website: Fish Oil and the Track Your Plaque Program - Is More Better?

ERA JUMP: Omega-3 fatty acids and plaque

1. August 2008 William Davis (5)

The results of the uniquely-constructed ERA JUMP Study were just released, a fascinating study of the relationship of omega-3 fatty acids to coronary and carotid plaque.

The study adds insight into why the Japanese experience only one third of the heart attacks of Americans, and why Japan occupies the bottom of the list for least heart attacks among all developed countries.

The Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort Study (ERA JUMP), a collaborative U.S.-Japanese effort, compared three groups of men:

-- 281 Japanese men living in Japan
-- 306 non-Japanese men living in the U.S. (Pittsburgh, Pennsylvania)
-- 303 Japanese Americans (having both parents Japanese without “ethnic admixture”) living in Hawaii.

The last group represents a group that is genetically similar to the group in Japan, but exposed to an American diet and lifestyle.

Three main measures were compared:

-- Blood levels of omega-3 fatty acids, EPA and DHA)
-- Carotid intimal-medial thickness (CIMT, the thickness of the carotid artery lining that can serve as an index of body-wide atherosclerosis)
-- Coronary calcium (heart scan) scores.

Interestingly, at the start of the study, the Japanese men possessed an overall cardiovascular risk profile worse than the Americans: Though more slender (BMI 23.6), Japanese men were more likely to be smokers, alcohol drinkers, had more high blood pressure, and were less likely to take cholesterol medications. The Americans, conversely, although heavier (BMI 27.9), were less likely to be smokers and drinkers, and had a four-fold greater use of cholesterol medications.

The Japanese Americans were the most likely to be hypertensive, diabetic, with a similar proportion of overweight as the non-Japanese Americans.

Despite the overall greater heart disease risk for profile for Japanese men, compared to non-Japanese Americans they had 10% less CIMT. In addition, only 9.3% of Japanese men had abnormal coronary calcium scores vs. 26.1% of non-Japanese Americans. Japanese-Americans were the worst, however, with nearly 10% more CIMT than non-Japanese Americans and 31.4% with abnormal calcium scores.

The most intriguing finding of all was the fact that, of all the various groups and degrees of atherosclerosis, whether gauged via CIMT or coronary calcium scores, the blood level of omega-3 fatty acids was inversely related, i.e., the greater the omega-3 blood level, the less plaque by either measure was detected.

Japanese men had the highest omega-3 blood levels: twice that of the non-Japanese Americans. The Japanese-Americans had levels only slightly greater than non-Japanese Americans.

While other studies, like the GISSI Prevenzione study, have persuasively demonstrated that omega-3 fatty acids substantially reduce heart attack, a weak link in the omega-3 argument has been a study that links greater omega-3 intake with less atherosclerosis. The unique construction of the ERA JUMP Study, employing two groups with sharply different omega-3 intakes, very powerfully argues for the plaque-inhibiting effects of this fraction of fats.

How much omega-3 fatty acids do Japanese people eat? Estimates vary, depending on part of the country, coastal vs. inland, age, etc., but Japanese tend to ingest anywhere from 5 to 15-times more omega-3 fatty acids than Americans. The actual intake of omega-3 fatty acids (EPA +DHA) in Japanese ranges from 850 to 3100 mg per day.

Mediterranean diet and blood sugar

31. July 2008 William Davis (6)

Data such as that from the Lyon Heart Study have demonstrated that a so-called Mediterranean diet substantially reduces risk for heart attack.

But there are aspects of the Mediterranean diet and lifestyle that are not entirely sorted out.

For instance, what specific component(s) of the diet provide the benefit? Is it olive oil and linolenic acid? Is it red wine? Is it the reduced exposure to processed snack foods that Americans are indundated with? Is it their more slender builds and greater tendency to walk? How about exposure to the Mediterranean sun? What about the inclusion of breads, since in the Track Your Plaque program I advocate elimination of wheat products for many abnormalities?

Anyway, here's a wonderfully thoughtful set of observations from Anna about her experiences traveling Italy, trying to understand the details of the Mediterranean diet while also trying to keep blood sugar under control.


I just returned from a two week stay in Italy, doing a bit of my own "Mediterranean Diet" experiments. When practical, we sought out food sources and places to eat that were typical for the local area, and tried as much as possible/practical to stay away from establishments that mostly catered to tourist tastes. I was really curious to see how the mythical "Mediterranean Diet" we Americans are urged to follow compared to the foods really consumed in Italy.

The first week, we stayed in a rural Tuscan farmhouse apartment (agriturismo), so many, if not most of our meals were prepared by me with ingredients I bought at the local grocery store (Coop) or the outdoor market in Siena. In addition, I purchased really fantastic free-range eggs from the farm where we were staying. (Between some language issues and seasonality, eggs and wine were what we could buy from them - though I was tantalized by the not-quite-ripe figs heavy on many trees). Mostly, our meals consisted of simple and easily prepared fresh fruits and vegetables, rustic cured meats (salami, proscuitto, pancetta, etc.) hand-sliced at the deli down the road, fresh sausages, various Italian cheeses, plus plenty of espresso. It was a bit disappointing to find underripe fruit & tomatoes as well as old green beans in the grocery stores, not to mention too many low fat and highly processed foods, but all over Europe the food supply is becoming more industrialized, more centralized, and homogenous, so I'm not too surprised that it happens even in Italy. But even with the smaller grocery store size, the amount of in-season produce was abundant, yet one still was better off shipping from the perimeter of the store, venturing into the aisles only for spices, olive oil, vinegar, coffee, etc. Without the knowledge of where to go and the language to really talk in depth about food with people, I wasn't able to find truly direct and local sources for as many foods as I would have liked, but still, we ate well enough!

The first week I maintained blood sugar levels very similar to those I get at home, because except for the Italian specialties, we ate much like we always do. A few rare exceptions to my normal BG tests were after indulging in locally made gelato or a evening limoncello cordial, but even then, the BG rise was relatively modest and to me, acceptable under the circumstance. Even with the gelato indulgences, it felt like I might have even lost a few pounds by the end of the first week and my FBG didn't rise much over 100.

The second week we stayed in two cities (Florence & Rome), and I didn't prepare any of my own food because I didn't have a kitchen/fridge. I found it impossible to get eggs anywhere for breakfast, and the tickets our hotels provided for a "continental" breakfast at a nearby café/bar was always for a coffee or hot chocolate drink and some sort of bread or roll (croissant, brioche, danish, etc.). At first I just paid extra for a plate of salami and cheese if that was available - or went to a small grocery store for some plain yogurt, but then I decided to go off low-carb and conduct a short term experiment, though I didn't consume nearly as many carbs as a typical Italian or tourist would.

So I breakfasted with a brioche roll or plain croissant for breakfast with my cappuccino, but unfortunately no additional butter was available. I didn't feel "full" enough with such a breakfast and I was usually starving an hour or two later. Additionally, when I ate the "continental" breakfast, I noticed immediate water retention - my ankles, lower legs, and knees looked like someone else's at the end of a day walking and sightseeing, swollen heavy. Exercising my feet and lower legs while waiting in lines or sitting didn't seem to help.

Food is much more expensive in Europe than in the US, and the declining US$ made everything especially expensive (not to mention the higher cost of dining out rather than cooking at home), so we tried to manage food costs by eating simple lunches at local take-away places, avoiding the corporate fast food chains. I was getting tired of salami/proscuitto & cheese plates, but the typical "quick" option was usually a panini (sandwich). At first I tried to find alternatives to paninis, but the available salads were designed for side dishes, not main meals and rarely had any protein, and the fillings of the expensive sandwiches were too skimpy to just eat without the bread. So I started to eat panini, although I sometimes removed as much as half of the bread (though it was nearly always very excellent quality pan toasted flatbreads or crusty baguette rolls, not sliced America bread). So of course, my post-prandial BGs rose, as did my FBG. I also found my hunger tended to come back much too soon and I think overall I ate more than usual in terms of volume.

Then we deviated from the "Italian" lunch foods and found a better midday meal option (quick, cheaper, and easier to customize for LC) - stopping at one of the numerous kebab shops and ordering a kebab plate with salad, hold the bread (not Italian, but still Mediterranean, I guess). I felt much better fueled on kebab plates (more filling and enough protein) than paninis, though I must say I still appreciated the taste of caprese paninis (slices of fresh mozzerella and tomato, basil leaves, mustard dressing on crusty, pan-toasted flat bread). If I followed my appetite, I could have eaten two caprese paninis.

We had some great evening dinners, at places also frequented by locals. This often was a fixed price dinner of several courses ("we feed you what we want you to eat"). Multi-course meals included house wine, and invariably consisted of antipasta (usually LC, such as a cold meat and cheese plate), pasta course (much smaller servings than typical US pasta dishes), main course plus some side vegetables, and dessert/coffee. These were often the best meals we experienced, full of local flavor and tradition (sometimes with a grandmotherly type doing the cooking), and definitely of very good quality, though we noticed the saltiness overall tended to be on the high side. I ate from every course, including some of the excellent bread (dipped in plenty of olive oil) and usually about half of the pasta served (2 oz dry?), plus about half of the dessert. After these meals I always ran BGs higher than usual, varying from moderately high (120-160 - at home I would consider this very high for me) to very high (over 180). By late in the week, my FBG was into the 115 range every morning (usually I can keep it 90-100 on LC food). Nearly everything that week was delicious, well-prepared food, but the high carb items definitely were not good for my BG control in the long run.

And most days I was doing plenty of walking, sprinting for the Metro subway trains, stair climbing (4th and 5/6th floor hotel rooms!), etc. but since I didn't have my usual housework to do, it probably wasn't too different from my usual exertion level.

So it was very interesting to experience the "Mediterranean Diet" first hand. Meats and cheeses were plentiful, fruits and vegetables played a much more minor role (main courses didn't come with vegetables other than what was in the sauce, but had to be ordered as additional items), but the overall carbs were decidedly too many. As I expected, it wasn't nearly as pasta-heavy as is portrayed in the US media/health press, but it is still full of too much grain and sugar, IMO. Low fat has become the norm in many dairy products, sadly, and if the grocery stores are any indication, modern families are gravitating towards highly processed, industrial foods. Sugar seems to be in everything (I quickly learned to order my caffe freddo con panno or latte sensa zuccero - iced coffee with cream or milk without sugar) after realizing that adding lots of sugar was the norm).

And, after several days of breakfasting at the café near our Rome hotel (where carbs were the only option in the morning), I learned that our very buff, muscular, very flat-stomached, café owner doesn't eat pasta (said as he proudly patted his 6 pack abs). I probably could have stuck closer to the carb intake I know works better for my BG control, but I figured if I was going to go off my LC way of eating and experiment, this was the time and place.

And yes, there were far fewer really obese people than in the US and lots of very slender people, but I could still see there were *plenty* of overweight, probably pre-diabetic and diabetic Italians (very visible problems with lower extremities, ranging from what looked like diabetic skin issues, walking problems, acanthosis nigricans, etc.). Older people do seem to be generally more fit than in the US (fit from everyday life, not exercise regimes), but there were plenty of "wheat bellies" on men old and young, even more young women with "muffin tops", and simply too many overweight children (very worrisome trend). So it may well be more the relaxed Italian way of living life (or a combination of other factors such as less air conditioning, strong family bonds, lots of sun, etc?) that keeps Italian CVD rates lower than the American rates, more than the mythical "Mediterranean diet".

Who is your doctor?

27. July 2008 William Davis (7)

Primary care physicians are the initial entry point for healthcare for the majority of Americans.

Develop pneumonia; go to your family or internal medicine physician (internist) to be prescribed an antibiotic. Need your blood pressure or cholesterol checked? Develop a sore knee or swelling in your leg? Once again, go to your primary care physician.

Primary care physicians are a patient’s guide to a bewildering array of technology and specialists. If you require a specific diagnostic test or consultation with a specialist, your primary care physician will help you navigate through the maze, choosing the path that is best for you. He or she will order a chest x-ray for a cough and fever, provide vaccines to prevent flu or pneumococcal pneumonia, perform an annual physical. If you require hospitalization, your primary care physician will admit you. He or she will order diagnostic tests like MRI’s, ultrasounds, x-rays, and blood testing, usually performed in the hospital or a hospital-owned facility. If you require the services of a gastroenterologist, orthopedist, general surgeon, or neurologist, your primary care physician will refer you to the appropriate specialist.

That’s how it’s supposed to work, at least in principle. In fact, during the first eight decades of the 20th century, it did work that work way for the most part. Your primary care physician acted not just as a provider of healthcare, but as your advocate, someone who knew you and worked to protect your welfare. Your family doctor often knew your parents, maybe even delivered you at birth, and cared for your children. His children often went to the same schools as your children. He and his family lived in the same town and sometimes went to the same church.

That hardly happens any more. It’s more likely you got the name of your primary care physician from a doctor referral service provided by a hospital. Or you picked a name off a list provided by your health insurer. It’s also common to see one doctor, only to see another a year later. Two, three, or more different primary care physicians over a five-year period are common. Doctors come and go, since physician turnover in clinics and practices has been on the increase for years. Insurance companies frequently force policyholders to change doctors, requiring you to choose from a list.

The end result of this shuffling of primary care is increasing impersonality of the relationship. You probably don’t know your primary care physician outside of the 10-minute interaction you had six months ago. She probably never met your mother and will likely not care for your children. Two years from now, she will likely not be your doctor any more, replaced by someone else who obtains the details of your health from a chart. Your chart is more likely to be electronic, with the details of your health history listed in a checklist. There’s little room to detail the idiosyncrasies and quirks of your unique personality or health profile. Throw into this impersonal equation the fact that many doctors have become scared of patients because of potential for lawsuits, often over the most trivial of issues, or because of an error of oversight or misdiagnosis.

This flawed and impersonal system, though emotionally unsatisfying, can still work if each doctor who assumes a patient’s care maintains the ethic of putting health and welfare above all.

But what if your primary care physician is not just an advocate for your welfare, but is a representative of the hospital? What if there are hidden, unspoken financial incentives paid to your doctor to direct you to the hospital for diagnostic testing, hospitalization, and referral to specialists? If a headache becomes a $4800 MRI, or chest pain becomes a $4200 nuclear stress test, then a $14,000 heart catheterization, your primary care physician becomes the purveyor of far greater financial opportunity for the hospital. The entire interaction, founded on the proposition that your doctor actually cares about you, collapses in a heap of financially motivated testing and procedures. It appears to work, and you and your family can still obtain access to healthcare. The problem is that you’re likely to get too much of it.

This message has not been lost on the shrewd administrators at hospitals. Take a look at the ranks of primary care physicians who refer patients to some of your local hospitals. It is typical that a hospital system maintains several hundred primary care physicians on their payroll, all of whom are expected to refer patients to the hospital, cardiologists, and other proceduralists. Why so many?

Most primary care physicians today have signed contracts with a hospital. In other words, they are employees of the hospital. This practice is not unusual: the American Medical Association reported that 4 of 5 primary care physicians are now bound by such employment arrangements across the U.S. In effect, 80% of primary care physicians are legally bound by contract to direct patients to cardiologists who work at hospitals.

On top of contractual obligations, there are financial incentives for the volume of procedures that are generated as a result of referrals. The more procedures generated from an internist’s or family practitioner’s practice, the greater the end-of-year productivity bonus will be, not uncommonly totaling tens of thousands of dollars. Dr. Ted Phillips (not his real name, since he declined to allow me to use it) received a bonus check of $9,437 this year for his “productivity,” defined murkily as the return on specialist referrals. While the bonus may have helped him pay for his son’s college tuition, it clearly was a situation that made him acutely uncomfortable when asked.

Several primary care physicians are also quietly dismissed every year from the ranks of employed physicians for not maintaining a minimum flow of patients into the system.

Another hazardous point of entry: Many patients enter the hospital through the emergency room (ER). A patient in the emergency room is at his or her most vulnerable, seeking help for an urgent complaint and usually willing to accept whatever the ER physician advises. Hospitals know this. That’s why many systems insist that the ER physicians be employees of the hospital, with their practice habits subject to control. A patient goes to the ER with chest pain or breathlessness. The worst thing that can happen from a financial standpoint is for the patient to be evaluated and discharged. For this reason, a growing number of hospitals employ ER physicians, then proceed to legislate practice patterns. Consulting a cardiologist is strongly encouraged, since they generally provide access to the downstream revenue-producing procedures offered in the hospital. That way, what might have been a four hour, $2500 ER visit is converted into a $10,000 to $40,000 hospital stay, even when nothing was wrong in the first place. There are millions of people nationwide who have the hospital bills to prove it after being discharged with a diagnosis of indigestion.

Caveat emptor: Buyer beware.

The “Heart Healthy” scam

27. July 2008 William Davis (1)
Like many scams, this one follows a predictable formula.

It is a formula widely practiced among food manufacturers, ever since food products began to jockey for position based on nutritional composition and purported health benefits.

First, identify a component of food, such as wheat fiber or oat bran, that confers a health benefit. Then, validate the healthy effect in clinical studies. Wheat fiber, for instance, promotes bowel regularity and reduces the likelihood of colon cancer. Oat bran reduces blood cholesterol levels.

Second, commercialize food products that contain the purported healthy ingredient. Wheat bran becomes Shredded Wheat, Fiber One, and Raisin Bran cereals and an endless choice of “healthy” breads. Oat bran becomes Honey Bunches of Oats, Quaker’s Instant Oatmeal, and granola bars. Even if many unhealthy components are added, as long as the original healthy product is included, the manufacturer continues to lay claim to healthy effects.

Third, as long as the original healthy ingredient remains, get an agency like the American Heart Association to provide an endorsement: “American Heart Association Tested and Approved.”

The last step is the easiest: just pay for it, provided the product meets a set of requirements, no matter how lax.

You will find the American Heart Association certification on Quaker Instant Oatmeal Crunch Apples and Cinnamon. Each serving contains 39 grams carbohydrate, 16 grams sugar (approximately 4 teaspoons), and 2.5 grams fat of which 0.5 grams are saturated. Ingredients include sugar, corn syrup, flaked corn, and partially hydrogenated cottonseed oil. Curiously, of the 4 grams of fiber per serving, only 1 gram is the soluble variety, the sort that reduces cholesterol blood levels. (This relatively trivial quantity of soluble fiber is unlikely to impact significantly on cholesterol levels, since a minimum 3 grams of soluble fiber is the quantity required, as demonstrated in a number of clinical studies.) Nonetheless, this sugar product proudly wears the AHA endorsement.

Thus, a simple component of food that provides genuine benefit mushrooms into a cornucopia of new products with added ingredients: sugar, high fructose corn syrup, corn starch, carageenan, raisins, wheat flour, preservatives, hydrogenated oils, etc. What may have begun as a health benefit can quickly deteriorate into something that is patently unhealthy.

There’s a clever variation on this formula. Rather than developing products that include a healthy component, create products that simply lack an unhealthy ingredient, such as saturated or trans fats or sodium.

Thus, a ¾-cup serving of Cocoa Puffs cereal contains 120 calories, no fiber, 14 grams (3 ½ teaspoons) of sugar—but is low in fat and contains no saturated fat. Proudly displayed on the box front is an American Heart Association stamp of approval. It earned this stamp of approval because Cocoa Puffs was low in saturated, trans, and total fat and sodium. Likewise, Cookie Crisp cereal, featuring Chip the Wolf, a cartoon wolf in a red sweater (“The great taste of chocolate chip cookies and milk!”), has 160 calories, 26 grams carbohydrate and 19 grams (4½ teaspoons) of sugar per cup, and 0 grams fiber—but only 1.0 gram fat, none saturated, thus the AHA check mark. (Promise margarine, made with hydrogenated vegetable oil and therefore containing significant quantities of trans fats, was originally on the list, as well, but removed when the trans fat threshold was added to the AHA criteria.)

It is this phenomenon, the sleight of hand of taking a healthy component and tacking on a list of ingredients manageable only by food scientists, or asserting that a product is healthy just because it lacks a specific undesirable ingredient, that is a major factor in the extraordinary and unprecedented boom in obesity in the U.S. Imagine the chemical industry were permitted such latitude: “Our pesticide is deemed safe by the USDA because it contains no PCBs.” Such is the ill-conceived logic of the AHA Heart-Check program the "Heart Healthy" claims.

It’s best we keep in mind the observations of New York University nutritionist and author of the book, Food Politics, Marion Nestle, that “food companies—just like companies that sell cigarettes, pharmaceuticals, or any other commodity—routinely place the needs of stock holders over considerations of public health. Food companies will make and market any product that sells, regardless of its nutritional value or its effect on health. In this regard, food companies hardly differ from cigarette companies. They lobby Congress to eliminate regulations perceived as unfavorable; they press federal regulatory agencies not to enforce such regulations; and when they don’t like regulatory decisions, they file lawsuits. Like cigarette companies, food companies co-opt food and nutrition experts by supporting professional organizations and research, and they expand sales by marketing directly to children, members of minority groups, and people in develop countries—whether or not the products are likely to improve people’s diets.”

Qualms over just how heart-healthy their products are? Doubtful.

Exploitation of trust

25. July 2008 William Davis (5)
Once upon a time, the tobacco industry was guilty of conducting a widespread, systematic, highly organized campaign to deliver their product to as much of the unsuspecting public as possible.

As clinical data mounted linking smoking and health problems like cancer and heart disease, tobacco producers labored fiercely to counter these claims despite darkening public sentiment. When individual company executives were questioned on why they continued to perpetuate the industry’s scandalous practices, the invariable justification offered was “Well, I had to pay my mortgage.” That tidy ends-justifies-the-means rationalization has a familiar ring when you examine the behavior of those in the heart "industry."

Things are not what they seem. The hospital, once an institution to serve the sick, a place for clergy, volunteers, and other altruists, has evolved into a business serving a thriving bottom line. You are the “product” they seek. The cardiologist, ostensibly in the service of alleviating heart disease, instead seeks to grow his checkbook by performing procedures that have nothing to do with lessening the burden of heart disease. He dives into the water to save drowning victim after drowning victim, but fails to simply toss in the life preserver that has been close at hand all along.

The woeful family practitioner, who is expected to bear undue responsibility for the broad spectrum of health, ignorantly permits heart disease to grow under his or her nose and, by default, allows heart disease to become the exclusive province of the proceduralist. Worse, the family practitioner or internist in the employ of the hospital (a situation that has quietly grown to encompass 80% of all primary care physicians) labors to fatten hospital business by directing patients into hospital services. The comparative lowly incomes of the primary care physician are substantially supplemented by participating in this huge revenue-generating machine called heart care.

The astounding grasp of the system has caused one of every 10 adults in the U.S. to have undergone a heart procedure. The lemming-like procession to the hospital creates a crowd mentality among some sectors of the frightened public. “My friends and neighbors have all had bypass operations. Sooner or later I guess it’s going to be my turn.”

Tragically, the system has grown through the exploitation of trust. The faith we have in doctors, hospitals, and the institutions and people associated with healthcare has been subverted into the service of profit. Many practitioners and institutions choose to operate under the guise of doing good, but instead capitalize on the public’s willingness to accept as fact the need for major heart procedures and all its associated costly trappings.

Bait and switch

24. July 2008 William Davis (0)
"When banks compete, you win.”

The TV ad opens with a 60-something man sitting in his living room, talking to a three-piece suit-clad, 30-something banker. The older man is explaining to the dismayed younger man why he’s going to use Lending Tree loan service for a home loan.

“But Dad, I’m you’re son!” the younger whines.

Many of Lending Tree’s clients have collaborated in filing a multi-million dollar class action suit against the company, claiming “bait and switch” tactics. They claim that home buyers are lured by low interest rates or low closing costs on a home loan. Once the buyer concludes the hassle of filling out numerous forms, the suit accuses Lending Tree of making a switch to a costlier loan.

Bait and switch is among the oldest con games around. If you’ve ever bought a car from a car dealer, chances are you’ve had your own little brush with this deception. The ad promises the SUV you’ve wanted for only $299 per month. Only, once you get there, the salesman informs you that only a limited number of special deals were available and they’ve run out. But he’s still got a really good deal right over here!

Most of us recognize that we’ve been hookwinked. Yet we still go along and buy a car from the dealer.

What if it’s not a sleazy salesman behind the pitch, but a physician. If it’s hard to resist the sales pitch at the car dealership, it can be near impossible to ignore the advice of your doctor. But the truth is often loud and clear: in many instances, it is a genuine, bona fide, and fully-certified scam.

Among the most common bait-and-switch heart scams: Your cholesterol is high. The sequence of subsequent testing is well-rehearsed. “Gee, Bob, I’m worried about your risk for heart disease. Let’s schedule you for a nuclear stress test.”

The stress test, like 20% or more of them, is “falsely positive,” meaning abnormal even though there’s nothing wrong with you. Another 30% are equivocal, not clearly abnormal but also not clearly normal. Now up to 50% of people tested “need” a heart catheterization in the hospital to clarify this frightening uncertainty. You might end up with a stent or two, even bypass surgery. Your simple $20 cholesterol panel has metamorphosed into $100,000 in hospital procedures.

That familiar sequence is followed thousands of times, seven days a week, 365 days a year.

If a disease lacks a procedure . . . create one

24. July 2008 William Davis (1)
Congestive heart failure is among the most common diagnoses in the hospital nowadays.

Congestive heart failure is the result of injury to the heart muscle such as that occurring during heart attack, viral infections of the heart (myocarditis), poorly controlled high blood pressure, and a smattering of other rare causes. Eight million Americans with congestive heart failure account for over one million hospital admissions annually (AHA Update, 2007). It has become so common, in fact, that it has ranked as number one cause for hospital admission for the last several years.

Heart failure is a frightening condition causing the sufferer to gasp for breath. Excess fluid accumulates in the lungs, amplifying the work of breathing and imparting a feeling of unease. Some heart failure sufferers struggle to the point of blacking out or requiring mechanical ventilation on a respirator.

There are a number of standard treatments for heart failure that usually rapidly rescue the patient from the brink of respiratory failure. These generally consist of intravenous diuretics that force the kidney to clear excess water rapidly, medications to increase heart muscle strength, and other treatments. It’s not uncommon for a heart failure patient to drop 10–20 lbs. in water weight with treatment. The treatments are quite effective for the majority of patients with rapid relief of the breathlessness generally obtained within hours.

However, the problem with congestive heart failure is not generally the rapidity or effectiveness of acutely providing relief, it is the chronic recurring nature of the disease. Someone can come to the hospital, obtain prompt treatment with relief of the breathlessness within 48–72 hours, only to return to the hospital in several weeks with a recurrence of the same process.

As common as congestive heart is in hospitals, it has also presented the perennial problem: how to convert this frequent reason for hospitalization into a profit opportunity. Some people who experience heart failure will undergo the usual sequence of heart procedures of heart catheterization, stents, bypass surgery, valve surgery, etc. But, because heart failure tends to be a repeatedly recurring event, even patients tire of the “need” for heart procedures. Then how can more heart failure occurrences be converted into profitable events?

A unique principle operates in the medical device market: If a disease lacks a procedure . . . create one.

Several problems are solved by such a principle. First, procedures are much more generously reimbursed by insurers than standard medical care without procedures. Two, the physician is provided an opportunity to also bill at a higher level. Third, patients often love the more dramatic, heroic nature of procedures, whether or not there is true benefit.

To the rescue of the poorly reimbursed area of congestive heart failure walks a Minnesota company called CHF Solutions, Inc., manufacturers of the Aquadex device.

Cost? $14,500 plus $900 per filter every time a patient gets one treatment. The Aquadex works by a decades-old process called ultrafiltration, used for many years but used principally for kidney failure not severe enough to require regular dialysis. New York cardiologist Howard Levin simply adapted the process, using smaller catheters inserted into the arm veins, in 2000. As in conventional ultrafiltration, blood is taken from the body from a catheter, passed through a filter that removes excess water, then returned to the body.

This is a serious effort. Dr. Levin raised $51 million in venture backing on top of $12 million seed capital. The device sailed through the Food & Drug Administration in June 2002, since it was labeled a newer form of ultrafiltration, thereby obtaining approval through the FDA’s 501k rule, a minor modification of existing technology. (Many truly technologically unique devices do come to market and therefore require the full process of FDA approval, a generally lengthy and costly process for devices. However, there’s another way: bill a device as “substantially equivalent” to an existing technology and the approval process is relatively quick and easy.)

In an industry publication, Cath Lab Digest, Dr. Levin was interviewed in February, 2003, and proclaimed, “We can treat many of the symptoms of heart failure, but we’re a long ways off from a cure. That’s why new technologies are so exciting, such as LVADs for the very sickest heart failure patients; biventricular pacing for the small subset of patients who seem to benefit from it; and simplified ultrafiltration such as the System 100 that can be applied to a broad range of congestive heart failure patients with fluid overload. “

What does this have to do with heart scans and heart disease reversal? Nothing-directly. I highlight this phenomenon because it caricatures how things work in medicine and health care in general, more so in cardiovascular diseases in which the profit motive is especially deeply ingrained. Focus on a need, then generate a profitable treatment for it. Profits are what drive growth, marketing, sales, and expansion into new revenue-generating niches.

Sadly, the reverse principle does not work: Replace profitable procedures with unprofitable strategies, regardless of their effectiveness. Replacing coronary angioplasty and coronary stent implantation, or bypass surgery, with intensive prevention efforts is no easy matter. Just witness the enormous resistance to the concept of early heart disease detection achieved with heart scans. A day doesn’t go by without a major media outlet bashing heart scans, or confusing them with CT coronary angiograms with claims of excessive radiation.

But the mounting volume of criticisms against heart scans also means that they are gaining some traction in mainstream thinking. But will there be a day when they replace the need for profitable procedures? I believe they will, when coupled with a powerful program of prevention, but don’t hold your breath.

"I have never seen regression"

29. March 2007 William Davis (0)
At a presentation at the American College of Cardiology meetings in New Orleans yesterday (March 27, 2007), Dr. Arthur Agatston declared "I have been doing CT for many years, and I have never seen regression."

Whooooaaaa. Wait a minute here. I have great respect for the work Dr. Agatston has done over the years. He is, after the originator of the scoring algorithm that allows us to score CT heart scans (though a more accurate measure, the volumetric score, is the one we often use behind closed doors because of modestly increased accuracy and reproducibility). His diet program, the South Beach Diet, has achieved enormous success and is indeed an effective approach for both weight loss and correction of many weight-related causes of heart disease.

But he has never seen regression? Why would this be when we see it all the time? When we see heart scan scores drop 30%, it's hard to believe that with some savvy he has never seen regression (drop in score).

I can only attribute the difference to the more intensive endpoints we advocate (e.g., 60-60-60 for lipid values); the incorporation of adjuncts like fish oil, vitamin D, l-arginine; attention to non-cholesterol issues and intensified treatments for each. I doubt that the populations we see differ substantially.

As much as I admire Dr. Agatston's accomplishments, I believe that he is behind the times on this issue. No regression is so starkly different from the Track Your Plaque experience. I believe that relying only on statin drugs and diet will slow but will not stop plaque growth. It will also rarely, if ever, drop your score.

Attention to detail and a little insight into better preventive strategies really pays off. While not everyone in the Track Your Plaque experience will drop their score, a substantial number do. Many more slow plaque growth dramatically. And, as time goes on, our track record gets stronger and stronger.

COURAGE to do better

28. March 2007 William Davis (0)
The results of the long-awaited COURAGE Trial were announced today at the American College of Cardiology meetings in New Orleans.

In this trial, 2200 participants with stable coronary disease (i.e., not unstable, in which heart attack or death is imminent) were randomly assigned ("randomized") to either angioplassty/stent or "maximal medical therapy." Medical therapy means such things as aspirin, beta blocker drugs, and statin cholesterol drugs. There was virtually no difference between the groups in rate of heart attack and death from heart disease over a period of up to 7 years.

These results have caused a stir in the media and my colleagues, trying to sort out of the implications. However, I think there's one observation in particular worth making for those of us who tend to scoff at the conventional approach to coronary disease. That is, 1 of 5 people had a heart attack or died from heart disease in both groups. That's a lot. Even more ended up with a procedure (angioplasty, stent, or bypass). In other words, the "maximal medical therapy" instituted in participants was hardly a success. Though angioplasty and stenting failed to prove superiority, both really stunk. Both permitted a lot of catastrophes to occur.

"Maximal medical therapy," in other words, is a laughable concept. It doesn't include raising HDL, suppressing small LDL, reducing Lipoprotein(a), addressing inflammatory issues. It does not include omega-3 fatty acids from fish oil, nor does it address the severe degrees of vitamin D deficiency that are proving, in the Track Your Plaque experience, to be among the most potent causes of atherosclerotic plaque known. It includes a sad attempt at diet, as advocated by the American Heart Association, a diet that, in my view, causes heart disease and is distorted by the powerful political and financial influence of food manufacturers.

If the trial were to be done again, I'd like to see the "maximal medical therapy" arm be represented by a more effective program like the Track Your Plaque approach.

Value of a zero heart scan score

27. March 2007 William Davis (1)
Margaret is 73. She's a very good 73. She loves children and works full-time in a daycare. She manages her own household, goes to dinner at least once each week with one or more of her adult children. She is slender and has never been in the hospital--until she developed an abnormal heart rhythm called atrial fibrillation.

Most people who develop atrial fibrillation do so with no immediate identifiable cause. However, Margaret has been a widow since her husband died 15 years ago of a heart attack. She was therefore especially frightened of any heart issues in her own health. Her doctor also raised the question of whether atrial fibrillation might represent the first hint of future heart attack.

So we advised a CT heart scan. Score: zero, or no detectable plaque whatsoever. This put Margaret's risk for heart attack as close to zero as humanly possible. (Nobody is truly at zero risk for heart attack for a number of reasons. One reason is that people do irrational things like take cocaine or amphetamines, or they take too much decongestant medication, all of which can trigger heart attack.)

The heart scan settled it. Margaret has the sort of atrial fibrillation which likely simply develops as a result of "wear and tear" on the heart's electrical impulse conducting system and it has nothing to do with coronary heart disease or heart attack.

As that MasterCard commercial goes: Cost of a heart scan: About $200. Peace of mind: priceless.

You're at the cutting edge

26. March 2007 William Davis (3)
If you're a participant in the Track Your Plaque program for atherosclerotic plaque regression, you are at the cutting edge of health.

Few physicians give this issue any thought. Chances are, for instance, that if you were to bring up the subject of reversal of heart disease to your primary care physician, you'd get a dismissive "it's not possible," or " Yeah, it's possible but it's rare."

Ask a cardiologist and you might make a little more progress. He/she might tell you that Lipitor 80 mg per day or Crestor 40 mg per day might achieve a halt in plaque growth or a modest reduction of up to 5-6%. If they've tried this strategy, they would likely also tell you that hardly anybody can tolerate these doses for long due to muscle aches. I'd estimate that 1 of 10 of my colleagues would even be aware of these studies.

Both groups are, however, reasonably adept at diagnosing chest pain, an everyday occurrence in hospitals and offices. Chest pain, for them, is a whole lot more interesting. It holds the promise of acute catastrophe and all its excitement. It also holds the key to lots of hospital revenues. Did you know that 80% of all internal medicine physicians are now employees of hospitals? They're also commonly paid on an incentive basis. More revenues, more money.

Ask Drs. Dean Ornish or Caldwell Esselstyn about reversal of heart disease and they will tell you that a very low-fat diet (<10% of calories)can do it. That's true if you use a flawed test of coronary disease like heart catheterization (angiograms) or nuclear stress tests (Ornish calls them "SPECT"). It would be like judging the health of the plumbing in your house by the volume of water flowing out the spigot. It flows even when the pipes are loaded with rust.

In the Track Your Plaque experience, extreme low-fat diets (i.e., high wheat, corn, and rice diets) grotesquely exagerrate the small LDL particle size pattern, among the most potent triggers for coronary plaque growth. This approach also makes your abdomen get fatter and fatter and inches you closer to diabetes. Triglycerides go up, inflammation increases.

If you were able to measure the rust in the pipes, that would be a superior test. You can measure the "rust" in your "pipes," the atherosclerotic plaque in your coronary arteries, using two methods: CT heart scans or intracoronary ultrasound. Take your pick. I'd choose a heart scan. It's safe, accurate, inexpensive. I've performed many intracoronary ultrasounds for people in the midst of heart attacks or some other reason to go to the catheterization laboratory. But for well people, without symptoms, who are interested in identifying and tracking plaque? That's the place for heart scans.

In our program, 18-30% reductions in heart scan scores are common.

A stent--just in case

26. March 2007 William Davis (3)
Burt came to me last week. He'd received a stent a few months earlier. He'd been feeling fine except for some fatigue. A nuclear stress test proved equivocal, with the question of an abnormal area of blood flow in the bottom (inferior wall) of the heart.

"The doctor said I had a 50% blockage. Even though it wasn't really severe, he said I'd be better off with a stent, just in case."

Just in case what? What justification could there be for implanting a stent "just in case"? (The artery that was stented did not correspond to the area of questionable poor blood flow on the nuclear stress test.)

Just in case of heart attack? If that's the case, what about the several 20 and 30% blockages Burt showed in other arteries? The cardiologist was apparently trying to prevent the plaque "rupture" that results in heart attack by covering it with a stent. Why stent just one when there were at least 7 other plaques with potential for rupture?

That's the problem. And that's why stents do not prevent heart attack (unless the stent is implanted in the midst of heart attack, when the rupturing plaque declares itself.) Of course, when no plaque is in the midst of rupturing, as with Burt, there's no way to predict which plaque will do so in future. Since only one plaque was stented, there is a 7 out of 8 chance (87.5%) that the wrong plaque was chosen. And that's assuming that there aren't plaques not detected by catheterization angiogram; there commonly are. The odds that the right plaque was chosen would be even lower.

In other words, stenting one blockage that is slightly more "severely blocked" in the hopes of preventing heart attack is folly. If it's not resulting in symptoms and blood flow is not clearly reduced, a stent can not be used to prevent plaque rupture. A stent is not a device to be used prophylactically. It is especially silly when an approach like ours is followed, since plague progession is a stoppable process.

Note: This issue is distinct from the one in which symptoms and/or an abnormal stress test show clearly reduced blood flow and flow is restored by implantation of a stent. While some controversies exist here, as well, a stent implanted under these circumstances may indeed provide some benefit.

How will you know your score dropped?

25. March 2007 William Davis (0)
This issue came up twice this week.

Bill is a busy accountant. Two years ago, just after the tumult of the 2005 tax season was over, he got a CT heart scan. His score: 398. At age 53, this was a significant score. His internist did the usual: prescribed a statin (Zocor), told him to cut the fat in his diet, and be sure to exercise. (Yawn.)

Since then, Bill quit preparing tax returns and migrated to a less harried job in corporate accounting. It took two years since his heart scan for Bill to start thinking that perhaps his doctor's advice wasn't enough. If it was, he realized, everyone on a statin drug who made these minimal lifestyle changes would be cured of heart attack risk. Clearly not the case.

So Bill enrolled in the Track Your Plaque program. Our first step: Get another heart scan.

Bill was surprised. "Why another scan? I already had one!"

I explained to Bill that atherosclerotic plaque is like money: it grows in percentages, just like money in a bank account or in a mutual fund. If, for instance, you deposit $500 in a mutual fund and it yields 5% return, then after one year you will have $550. One year later, you will have 5% x $550, or $605. Another year: $665. In other words, growth is not 10% of the original amount you deposited. Growth is compounded, year over year. That's why money, when compounded, can grow so quickly.

Atherosclerotic plaque and your CT heart scan score do the same thing: they grow by a percentage of the current plaque quantity. In fact, we use the compound interest equation to calculate the annualized rate of plaque growth. But plaque grows at the extraordinary rate of 30% per year, on average. Imagine that was the rate of return on your money. You'd be the richest man or woman on earth.

Back to Bill. Now Bill, in his defense, was on a statin drug and did make modest efforts towards a (mis-guided) low-fat diet and walking four days per week. If, on a second CT heart scan, his score was:

398--No change. That's a success, since the expected rate of increase of 30% has been stopped. However, on his current program, this is highly unlikely. (I've seen it happen just once ever out of about 2000 people.)

250--Pop the cork on your champagne, because Bill needs to celebrate. He has substantially reversed his plaque. Highly unlikely on the current effort.

525 --The score is higher by 30%, so it has slowed, but it surely hasn't stopped. This is the most typical result on the sort of program Bill is following.

The message: Don't delay after your first heart scan score. It plaque grows like money with a huge return, there's no time like the present to take the steps to regain control.

Firefighters Face Added Risk of Fatal Heart Attack

22. March 2007 William Davis (1)
Firefighters are twice as likely to die from a heart attack in the line of duty than are policemen, and three times more likely than EMTs.

That's among the headlines run today because of a report in the New England Journal of Medicine documenting a dramatically higher risk for heart attack for fire fighters putting out fires. The above headline is from an excellent report run on NPR radio. You can listen to the webcast at http://www.npr.org/templates/story/story.php?storyId=9047656.

The story sparked comments from experts insisting that all fire fighters should have physicals, should be in better physical condition, should be covered by health insurance (the NPR report said that 1 out of 4 fire fighters lack health insurance). Judging from the indisputable risk firefighters encounter, these are all good ideas.

But if you've been following my blog or the Track Your Plaque program, you know that physicals alone are hopeless exercises for identifying hidden heart disease. Among the solutions: identify whether or not heart disease is present in the first place--do a CT heart scan.

In fact, several local fire companies in my area have done just that: insisting that all firefighters undergo a heart scan. When groups of people like firefighters arrange for heart scans, they gain the advantage of doing so en masse, thereby allowing many scan centers to offer a dramatically reduced price to the city, town, or village that is paying for them. I've even seen many firefighters scanned at no cost.

It would also help to have health insurance, be physically fit, and have a stress test (an exception to my view that stress tests are also useless to screen asymptomatic people for heart disease). But a CT heart scan would settle the question quickly, easily, undeniably, and inexpensively.

Prophylactic bypass surgery?

20. March 2007 William Davis (0)
This question comes up around once a week:

My CT heart scan score is ____. Wouldn't I be better off just getting a bypass (or stent, etc.) and getting it over with? If I know that heart attack is in my future, why not just get it over with?

The most recent source of this question was the wife of a patient. Jack had a heart scan score of 92 in 2005. He made very little effort to correct his causes, permitting pre-diabetic patterns to persist, failed to correct vitamin D, etc. and a repeat heart scan score showed a dramatic rise to 264.

Jack's wife asked whether he should just have a bypass.

There are several problems with this line of reasoning:

1) Bypass surgery does not reduce the long term risk for heart attack.

2) The risk of bypass surgery often outweighs the risk of an asymptomatic heart scan score.

3) Bypass surgery is a temporary "fix," a fancy Band Aid for a disease that progresses after the procedure. One bypass typically prompts another, and another...

4) Bypassing arteries that have vigorous blood flow often causes the bypass graft to not "take" and close within the first few days.


Thankfully, nobody in his right mind has proposed that we perform prophylactic bypass operations.

Of course, hospitals and surgeons would jump at the chance to perform procedures in anybody with some threshhold heart scan score. It would double or triple their business overnight. At $70,000 or more per procedure, they would dance in glee. Of course, you and I would pay for their new burst of wealth by a sharp increase in our health insurance premiums. Not only that, the people who underwent the procedure would not benefit.

Lipitor 80 mg

20. March 2007 William Davis (4)
I'm seeing more and more people taking 80 mg of Lipitor per day. For the most part, these are people who come in for another opinion after a stent or heart attack and are prescribed the drug during their hospitalization.

This practice is based on the results of the PROVE IT-TIMI 22 (PRavastatin Or atorVastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction) trial, and the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, both reported in 2005. In the PROVE IT Trial, 4,000 people experiencing heart attacks were treated with Lipitor (atorvastatin), 80 mg, or Pravachol (pravastatin), 40 mg. There was a reduction in events like recurrent heart attack from 13.1% in the Pravachol group to 9.6% in the Lipitor group. In the REVERSAL Trial, the Lipitor group also showed no plaque growth compared to the Pravachol group, which did progress, with disease tracked by intracoronary ultrasound.

I believe that many of my colleagues took the bait. In a half-hearted effort to reduce events and trend towards better coronary plaque control, writing a prescription for 80 mg rather than a lower dose has become increasingly popular.

Some problems: Despite the favorable tolerance to high dose Lipitor in these trials, I don't know anybody who can tolerate 80 mg per day for more than a few months in real life. In my experience, people inevitably end up with intolerable muscle aches.

Also, I believe it is folly to believe that we can regress coronary plaque on a broad scale by just using one drug that addresses only a single cause (i.e., LDL cholesterol). Yes, drug companies would argue that the statin drugs are so wonderful because of their so-called "pleiotropic", or non-lipid, effects like reducing inflammation. I have seen regression of plaque once using Lipitor alone. We struggle to reduce coronary plaque using a multi-faceted approach. It is highly unlikely that Lipitor alone at a 80 mg dose will be sufficient in most people to regress plaque. How about lipoprotein(a)? Or vitamin D deficiency? Lipitor has no effect on these patterns and people do not regress just by taking statin agents.

Orlistat for weight loss

19. March 2007 William Davis (3)
In early February, the FDA approved orlistat, formerly known as prescription Xenical, for over-the-counter sale. Orlistat is a blocker of fat absorption.

The new OTC version will be called "Alli" (pronounced like "ally") and will come at a dose of 60 mg to be taken three times a day with meals. Prescription Xenical came as a 120 mg tablet. However, the company claims that the reduced dose sacrifices only 5% in reduced fat absorption, dropping from 30% with Xenical to 25% with Alli. It will cost in the neighborhood of $1 to $2 per day, or $30-60 per month, far less expensive than the $110-150 for the prescription form.

Does it work? Is it worth the money? Clinical trials document around 5-10 lbs lost over a 3 to 6 month period, 50% greater than using diet and exercise alone.

Our experience is that it works, though inconsistently. Results depend heavily on how reliant you are on fat calories. If you were to follow a low-fat diet while on the drug, you likely will lose little or no weight, since there's little fat absorption to block. However, I have witnessed more substantial weight loss of 10-20 lbs. in people who follow a higher fat intake in their diet, e.g., a traditional American diet. However, these people gain the weight back immediately because they've made no effort to modify food choices.

It is messy. Even though the clinical trials claims modest inconvenient effects like gas and greasy stools, I have found that it is, without fail, a very annoying product that results in crampiness and frequent messy stools in nearly everybody.

The company has created a glitzy website that you can view at www.myalli.com and promises to provide a personalized program and support for registrants when it is up and running by summer 2007.
I think that's a good idea, since the drug itself is no more than a temporary fix unless it's combined with long-term diet changes. However, the website, I believe, oversells the value of the drug with a drug company's usual over-the-top hints and innuendoes without actually coming out with straight pitches of the truth.

Beware of the vitamin D-blocking effect of Orlistat. The period of time you take it may be a time to resort to some modest sun exposure (10-15 minutes; be careful not to burn), rather than than oil-based vitamin D capsules, in order to avoid the inevitable vitamin D plunge in blood level.

I am not a fan of orlistat, having seen it tried many times with minimal success. However, it is another option for those who are really struggling. Personally, I would try fasting or some of the other strategies we've detailed on the www.cureality.com website before I resorted to orlistat.
