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.

Blood sugar lessons from a Type I diabetic

23. July 2008 William Davis (15)

A friend of mine is a Type I, or childhood onset, diabetic. He's had it for nearly 50 years, since age 6. He's also in the health industry and is a good observer of detail.

He made the following interesting comments to me recently when talking about the effects of various foods on blood sugar:

"When I eat normally, like some vegetables or salad and meat, I dose up to 10 units of insulin to control my blood sugar.

"If I eat a turkey sandwich on two slices of whole wheat, I usually dose 15 units. The bread makes my blood sugar go to 300 if I don't.

"If I eat a Cousins's Sub [a local submarine sandwich chain], I dose 15 units. The bread really makes my blood sugar go up.

"I can only eat a Quarter Pound from McDonald's once a year, because it make my blood sugar go nuts. I dose 15-20 units before having it, and I feel like crap for two days afterwards.

"If I eat Mexican food, I have to dose 15-20 units. For some reason, it's gotten worse over the years, and I need to dose higher and higher.

"Chinese food is the absolute worst. I dose 20-25 units before eating Chinese. I'll often have to dose more afterwards, because my blood sugar goes so berserk."

Nothing beats the real-world observations on the impact of various foods on blood sugar than the observations of people with Type I diabetes. All the insulin they get is in a syringe. Dosing needs to match intake.

Personally, though I love the taste of Americanized Chinese food, I've always been suspicious of what exactly goes into these dishes. But I was unaware of the blood sugar implications.

The impact of Mexican I believe can be attributed to the cornstarch used in the tacos and tortillas, though I also wonder if there are other starches being snuck in, as well.

Lessons about omega-3s from Japan

23. July 2008 William Davis (7)

Japan provides a useful "laboratory" for studying the effect of a culture that relies heavily on eating fish.

The JELIS Trial, the topic of a previous Heart Scan Blog post, showed that supplementation with the single omega-3 fatty acid, EPA, 1800 mg per day (the equivalent of 10 capsules of 'standard' fish oil that contains 180 mg per day of EPA, 120 mg of DHA) significantly reduced heart attack in a Japanese population. Interestingly, this benefit was additive to the already substantial intake of omega-3 fatty acids among the general Japanese population, a population with a fraction of the heart attacks found in western populations like the U.S. (approximately 3% over 5 years in Japanese compared to several-fold higher in a comparable American group).

While there may be genetic and other cultural and lifestyle reasons behind the dramatically reduced cardiovascular risk in Japanese, it is undeniably at least partially due to the increased intake of omega-3 fatty acids from fish. Incidentally, the purported benefits of omega-3 fatty acids provide a vigorous counter-argument to the idea that all humans should be vegetarians.

Anyway, if we were to take some lessons from the Japanese and their greater habitual intake of omega-3 fatty acids from fish, they might include:

--Rural and coastal Japanese are the sub-populations with the highest reliance on fish, about a quarter-pound a day. (Gives new meaning to the idea of a "Quarter Pounder," doesn't it?) This is at least five-times greater than the intake of an average American.

--Likewise, the blood level of omega-3s in the blood of Japanese is 5-fold higher than in Americans.

--The average intake of omega-3s (EPA + DHA) among a broadly-selected population of Japanese is 850 mg per day (320 mg EPA; 520 mg DHA). Intake ranges from 300 mg per day all the way up to 3100 mg per day.

--Greater omega-3 intake (EPA + DHA) is associated with lesser carotid intimal-medial thickness, an index of body-wide atherosclerosis.

--Japanese have far less heart attack and stroke despite greater prevalence of smoking (nearly half of Japanese) and drinking.

--Total fat intake (percent of calories) is nearly identical between Americans and Japanese. It's the proportion of fat calories from omega-3 that is greater, the proportion of omega-6 that is less in Japanese.

The Japanese eat their fish in ways that we do not: As sashimi (raw, as with sushi in its various forms like Nigiri and Chirashi); fried in tempura; shaved, dried fish sprinkled on about anything you can imagine (it's not as bad as it sounds); as a snack, as in dried cuttlefish (which you can purchase in packages as a portable, sweetened fish that you eat on-the-run--I know it sounds awful, but don't poke fun at it until you've tried it); in "soups" with soba noodles. Fish is commonly consumed with rice and soy sauce, as well as other soy-based foods, such as tofu, miso (soy bean paste), or natto.

I believe that there are some lessons to take from the Japanese and their fish-consuming habits:

1) An omega-3 fatty acid intake of at least 1000 mg per day yields measurable cardiovascular benefits.

2) Despite the fears over mercury and pesticide residues in fish, this seems to not have played out to be a real-life effect in the Japanese, who consume five-fold greater quantities of fish.

3) My mother was right after all when she encouraged us to eat more fish.

DIRECT Study result: Low-carb, Mediterranean diets win weight-loss battle

19. July 2008 William Davis (14)

Drs. Iris Shai and colleagues released results of a new Israeli study, the Dietary Intervention Randomized Controlled Trial (DIRECT) Trial, that compared three different diet strategies. Of those tested, a low-carbohydrate diet was most successful at achieving weight loss.

You can find the full-text of the study on the New England Journal of Medicine website.

322 participants followed one of three diets over two year period. Compared head-to-head, the (mean) weight loss in each group was:

• 2.9 kg (6.4 lbs) for the low-fat group
• 4.4 kg (9.7 lbs) for the Mediterranean-diet group
• 4.7 kg (10.3 lbs) for the low-carbohydrate group

(Average age 52 years at start; average body-mass index, or BMI, 31.)

The conclusion was that the low-carb diet performed the best, with 60% greater weight loss, with the Mediterranean diet a close second.

The diets

The low-fat diet was based on the American Heart Association diet, with 30% of calories from fat (10% from saturated fat) and food choices weighted towards low-fat grains, vegetables, fruits, and legumes and limited additional fats, sweets, and high-fat snacks; calorie intake of 1500 kcal per day for women and 1800 kcal per day for men was encouraged.

The Mediterranean diet was a moderate-fat diet rich in vegetables, with reduced red meat, and poultry and fish replacing beef and lamb. Total calories from fat of 35% per day or less was the goal, with most fat calories from olive oil and a handful of nuts. Like the low-fat program, calories were limited to 1500 kcal per day for women, 1800 kcal per day for men.

The low-carbohydrate diet was patterned after the popular Atkins’ program, with 8% participants achieving the ketosis that Dr. Atkins’ advocated as evidence that a fat-burning metabolism was activated, rather than sugar-burning as fuel. For the 2-month “induction phase,” 20 grams of carbohydrates per day was set as the goal, followed by 120 grams per day once the weight goal was achieved. Unlike the other two diets, calories, protein and fat were unlimited.

Weight loss, lipids, inflammation

You can see from the weight loss graph that the low-carb approach exerted the most dramatic initial weight loss. Interestingly, much of the weight-loss benefit was lost as the carbohydrate intake increased, by study design, back to 120 mg per day. However, the other two diet approaches showed similar phenomena of “giving back” some of the initial weight loss.

The low-carbohydrate diet exerted the greatest change in cholesterol, or lipid, panels: increased HDL 8.4 mg/dl vs. 6.3 mg/dl on low-fat; the triglyceride response was the most dramatic, with a reduction of 23.7 mg/dl vs. 3.7 mg/dl on low-fat. Interestingly, the LDL cholesterol-reducing effect of all three diets was modest, with the most reduction achieved by the Mediteranean diet.

The inflammatory measure, C-reactive protein (CRP), was reduced most effectively by the low-carb and Mediterranean diets, least by the low-fat diet. HbA1c, a measure of long-term blood sugar, dropped significantly more on the low-carb diet.

When the final dietary composition was examined, interestingly, there really were only modest differences among the three diets, with 8% less calories from carbs, 8% greater calories from fat, comparing low-carb to low-fat, with Mediterranean intermediate.

Taken at face value, this useful exercise quite clearly shows that, from the perspective of weight loss and correction of metabolic parameters like triglycerides, HDL,CRP, and blood sugar, low-carbohydrate wins hands down, with Mediterranean diet a close second.

It also suggests that a return to a carbohydrate intake of 120 mg/day allows a partial return of initial weight lost, as well as deterioration of metabolic parameters after the initial positive changes.

Although the study has already received some criticism for such potential flaws as the modest number of Atkins’ followers achieving ketosis (8%), suggesting lax adherence, and the reintroduction of the 120 mg/day carbohydrate advice, I can suspect that these may have been compromises drawn to satisfy some Institutional Review Board. (Whenever a study is going to be conducted involving human subjects, a study needs to pass through the review of an Institutional Review Board, or IRB. IRB’s, while charged to protect human subjects from experimental abuses, also tend to be painfully conservative and will block a study or demand changes even if they are not dangerous, but just veer too far off the mainstream.)

However, several unanswered questions remain:

1) How would the diets have compared if the carbohydrate restriction were continued for a longer period, or even indefinitely? (The divergences would likely have been dramatic.)
2) Will low-carb exert the same cardiovascular event reduction that the Mediterranean approach has shown in the Lyon study and others?
3) Are there effects on health outside of the measures followed that differ among the three diets, such as cancer? (I doubt it, especially given the modest real differences over time. But this will be the objection raised by various "official" organizations.)

I would further propose that:

Low-fat diets are dead

The AHA will cling to their version of low-fat diet, based on difficulty in changing course for any large, consensus-driven organization, not to mention the substantial ($100’s of millions) revenues derived from endorsing low-fat manufactured products. The AHA

Boy, was I wrong!

1. August 2006 William Davis (0)

Around 10 years ago, I was talking to a balloon and stent manufacturer's representative, who was raving about some new device that was due for release to the market. Back then, the sky seemed the limit to cardiac device manufacturers, who were falling over themselves scrambling to design and market the next new device.

The angioplasty market then had ballooned (no pun intended) from nothing to a multi-billion dollar industry. Stents were just getting underway but clearly had potential for being at least as large.

But this was a time when preventive therapies were also beginning to get quite powerful. We had just gotten started doing CT heart scans and were excited about the possibilities, statin drugs were gaining evidence through clinical trials, and the power of many nutritional supplements was finally achieving validation. We were even learning the error of our prior low-fat ways.

So I broadly pronounced to the enthusiastic product representative, "In 10 years, balloons, angioplasty, and stents will occupy this little corner of cardiac care because prevention will have become so powerful. We won't talk about heart procedures. We'll talk about coronary plaque regression!"

I even advised the representative that he should consider a career change in anticipation of the coming wave of preventive strategies.

Was I ever wrong. Despite the power of heart disease prevention--which is indeed true--cardiac device and procedure technology has boomed, both in popularity as well as in revenue success. Device manufacturing and sales are hugely successful. Implanting devices into people is a hugely profitable enterprise.

Since my ill-timed comments to the salesman, Boston Scientific, a major manufacturer of stents and other cardiac devices, reported revenues of $6.2 billiondollars in 2005, a 12% increase over the prior year. Medtronic reported 2005 revenues of $11.3 billion, growing at 15% per year. Clearly, cardiac procedures are still quite popular--and profitable.

My timing was off, but not for long. The huge crest of change in preventive therapies is upon us. That's the premise behind the Track Your Plaque concept: heart disease prevention can't be found in a hospital, is not supported by cardiac device manufacturers, and is not being advocated by most cardiologists or primary care physicians. Yet the tools are getting better and better every day.

Those of you who succeed in halting or reducing your heart scan score are extremely unlikely to add to Boston Scientific's or Medtronic's revenues. Help me spread the word.

Don't forget how dangerous heart disease can be

29. July 2006 William Davis (0)

Sometimes it's easy to get smug when coronary plaque is a reversible process.

When you see people day in, day out, week in, week out, drop their heart scan scores, reversing what could be a dangerous disease, you can sometimes lose sight of just how dangerous coronary disease can be.

Whether I like it or not, I maintain a reasonably active role in hospitals out of necessity. I do need their services occasionally for people with advanced heart disease when I meet them (when regression is not the initial conversation for safety reasons), or valve disease is diagnosed, or someone shows up with congenital or heart muscle diseases. In other words, although we focus on coronary issues, there's more to heart disease than just coronary disease.

This unfortunate case just served to remind me how powerful coronary disease can be. Elizabeth, an active 67-year old, finally came to the hospital after suffering 6 months of chest pain and increasing breathlessness. She hated hospitals and hadn't seen a doctor in 30 years since she was successfully treated for cancer.

In those 30 years, she'd been quite active with family and a small business. But she also smoked 2 packs of cigarettes most of those years.

After she was admitted to the hospital, it became clear that Elizabeth had experienced one, if not several, heart attacks along the way. The entire front 2/3 of her heart was non-functional. If that wasn't bad enough, two of her heart valves were severely diseased and dysfunctional: Her aortic valve barely opened (aortic valve "stenosis", or stiffness) and the mitral valve leaked severely (mitral valve "insufficiency", or leakiness). All of this was confirmed with conventional testing in the hospital, including a heart catheterization.

Elizabeth ended up in emergency surgery--very unusual, by the way, for valve surgery of the sort she had--but died in the first few hours after her procedure. Her heart had simply been too damaged from her heart attacks, and the extraordinary stress of surgery that included two valves was too much. She died on the ventilator.

Coronary disease is a very serious matter. When I see cases like Elizabeth, it boosts my commitment to tell everyone that heart disease--when identified early enough--is a controllable, preventable, even reversible process. For poor Elizabeth, she was much too far down the path of severe, irreversible disease that control or reversal was simply not an option. She was in imminent danger of dying even upon arrival.

It's exciting yet sometimes frightening to know what you have in your hands: The means to control this monster called coronary disease. Use it wisely. But don't lose sight of what it can do it you permit it to grow, fester, and explode.

How many ways can you disguise sugar?

28. July 2006 William Davis (0)

I came across this shockingly silly report on AOL, who obtained their info courtesy Health Magazine:

The Best New Healthy Foods for Busy People
from Health

The foods on their list:

Kettle Brand Bakes Hickory Honey BBQ--the healthy claim is based on the lack of trans-fatty acids and low-fat.

Post Healthy Classics Raisin Bran Cereal Bars, Cranberry--Likewise, low-fat, sweet, and addictive means healthy to these people.

Amy’s Mediterranean Pizza With Cornmeal Crust --Please!!

Horizon Organic Colby Cheese Sticks --Because it's made by cattle without use of growth hormone or antibiotics, they declare this healthy. I guess we can ignore the saturated fat content and high total fat content.

100% Whole Grain Chips Ahoy! Cookies --You mean we can add the bran back to wheat products and make it healthy?!

This kind of mass-market marketing trickery leaves me incredulous. Don't believe it for a moment. This is typical of the food industry: Take one aspect of nutrition that is truly healthy, such as high-fiber, or low-fat, or organic. Then add undesirable, unhealthy ingredients. The current fad is to add lots of sugar and or sugar-equivalents (usually flour and other wheat products). Because there's one healthy ingredient, they'll call the end-product healthy, too.

If you want to see what health looks like if you indulge in "healthy" products like this, just look up and down the grocery aisles at your neighborhood grocery store. You're likely to see the results: Gross obesity, diabetes, and arthritis.

You won't, of course, see the huge acceleration of growth in coronary plaque, but it's there, ticking away.

To remind us what ideal body weight is: Watch an old movie!

26. July 2006 William Davis (0)

Jack was skeptical. At 273 lbs, 5 ft 11 inches, he felt that he was "just right".

"I feel fine. I don't see why you think I should lose weight," he declared. "In fact, when I lost 25 lbs a couple of years ago, everyone said I was too skinny!"

I showed Jack why: He had an HDL of 35 mg/dl, small LDL (over 90% of all LDL particles), an elevated blood sugar of 123 mg/dl (diabetes is officially 126 mg/dl or greater), high blood pressure, and increased inflammation (C-reactive protein). These were all manifestations that his body weight was too much for it to handle.

So I told Jack that we've all forgotten what ideal weight should look like. Our perception of "normal" has been so utterly and dramatically distorted by the appearance of our friends, family, co-workers, and other people around us that we've all lost a sense of what a desirable weight for health should be.

So I suggested to Jack that, if he wanted to rememember what ideal weight is and what people are supposed to look like, just watch old movies.

Old movies, like the 1942 production of Casablanca, or the 1952 production of Singin' in the Rain, show the body build that was prevalent in those days. Look at Humphrey Bogart or Gene Kelly--men with average builds, weighing 140-160 lbs--that's how humans were meant to look.

A report this morning on the Today Show showed the "after" photos of several people following bariatric (weight reduction) surgery. The "after" pictures, from the perspective of ideal weight and ideal health, remain hugely overweight.

We need to readjust our perceptions of weight. The average woman in the U.S. now weighs 172 lbs(!!!). Don't confuse average with desirable.

Diabetes is a choice you make

24. July 2006 William Davis (0)

Tim had heart disease identified as a young man. He had his first heart attack followed by a quadruple bypass surgery at age 38. Recurrent anginal chest pain and another small heart attack led to several stents over three procedures in the first four years after bypass.

Tim finally came to us, interested in improving his prevention program. You name it, he had it: small LDL, low HDL (28 mg/dl), lipoprotein(a), etc. The problem was that Tim was also clearly pre-diabetic. At 5 ft 10 inches, he weighed 272 lbs--easily 80 or more pounds overweight.

Tim was willing to make the medication and nutritional supplement changes to gain control over his seeminglly relentless disease. He even turned up his exercise program and lost 28 lbs in the beginning. But as time passed and no symptoms recurred, he became lax.

Tim regained all the weight he'd lost and some more. Now Tim was diabetic.

"I don't get it. I eat good foods that shouldn't raise my insulin. I almost never eat sweets."

I stressed to Tim that diabetes and pre-diabetes, while provoked acutely by sugar-equivalent foods (wheat products, breads, breakfast cereals, crackers, etc.), is caused chronically by excess weight. If Tim wants to regain control over his heart disease, he needed to lost the weight.

Unlike, say, leukemia, an unfortunate disease that has little to do with lifestyle choices, diabetes is a choice you make over 90% of the time. In other words, if you become diabetic (adult variety, not children's variety) as an adult, that's because you've chosen to follow that path. You've neglected physical activity, or indulged in too many calories or poor food choices, or simply allowed weight to balloon out of control.

But diabetes is also a path most people can choose not to take. And it is a painfully common choice: Nearly two-thirds of the adults in my office have patterns of pre-diabetes or diabetes when I first meet them.

Let me stress this: For the vast majority of adults, diabetes is a choice, not an inevitability.

I'll call the doctor when I feel bad!

Max just had his heart scan. He sat down with the x-ray technologist at the work console while she pointed out the white areas in his coronary arteries that represented plaque.

"It looks like you're going to have a fairly high score," the technologist commented. "The final report will be available after one of our cardiologists reviews your images."

Max shrugged. "Well, I don't feel anything. I'm always running around with work, with my kids, stuff like that. That's better than any stress test. I guess I'll worry about it if it starts to bother me."

You'd be surprised how common this view remains: If it's not bothering you, then just forget about it. It's easy to do, since you have no symptoms, nothing to impair your physical activities. But what are the potential consequences of ignoring your heart scan? Here's a few:

--Prevention and plaque reversal efforts are most effective the earlier you start. From a heart scan score viewpoint, the lower your starting score, the easier it is to gain control over it. More people will succeed in reducing their score when the starting score is lower.

--The role of prevention of heart disease instantly crystallizes when you know your score. Your LDL cholesterol of 142 mg/dl or HDL of 41 mg/dl no longer seem like just numbers of borderline signficance. Instead, they become useful tools to gain control over plaque. They cast your numbers in a new and clear light.

--Knowing your heart scan score today gives you a basis for comparison in future. Your score of, say 250, today, can be 220 in one year. Without your preventive efforts, it will be 30% higher: 325. That's a big difference!

--Sudden death or heart attack--can occur in up to 35-40% of people with hidden heart disease--without warning.

Don't even bother getting a heart scan if you're going to ignore it. I've said it before and I'll say it again: A heart scan is the most important health test you can get--but only if you do something about it.

Coenzyme Q10 and statin drugs

23. July 2006 William Davis (0)

Although drug manufacturers claim that muscle side effects from statin drugs occurs in only around 2% or people or less, my experience is very different.

I see muscle weakness and achiness develop in the majority of people taking Lipitor, Crestor, Zocor, Vytorin, etc. I'd estimate that nearly 90% of people get these feelings sooner or later.

Thankfully, the majority of the time these feelings are annoyances and do not lead to any impairment. Full-blown muscle destruction is truly rare--I've seen it once in over 10 years and thousands of patients.

The higher the dose of statin drug and the longer you take it, the more likely you're going to have muscle aches.

I experienced a strange phemomenon myself today. I worked outdoors for about 4 hours, pulling weeds, digging in the dirt, spreading topsoil. (I have an area of overgrowth in the front yard.) Admittedly, I worked pretty hard and it was a warm, humid day.

I was sore, as you'd expect at age 49. But, much more than that, I was exhausted--my muscles ached and I had barely enough strength to get up the stairs.

Hoping for some relief, I took an extra dose of coenzyme Q10. I usually take 50-100 mg per day. Today, when I felt this overwhelming muscle fatigue, I took an additional 200 mg. Within 10 minutes, I felt a surge of energy. It was, in fact, a perceptible, quite dramatic feeling.

I am thoroughly convinced, through my own experiences on Lipitor (I have a high LDL particle number despite a healthy lifestyle, among other abnormalities), and the experiences of many other people, that coenzyme Q10 can be an extremely useful tool to minimize the muscle aches and weakness of the statin drugs.

If you do indeed need to take one of these agents, coenzyme Q10 is worth knowing about. Supplementing coenzyme Q10 has, for me, been a real lifesaver. For many people, LDL reduction is a crucial part of their heart scan score control program. In my experience, many of them would not be able to take the drug without eozyme Q10.

Blast your LDL with oat bran and almonds

21. July 2006 William Davis (1)

Nearly all of us can use an extra boost in reducing LDL cholesterol. We have a large number of people, in fact, who have reduced LDL into the Track Your Plaque range of 60 mg/dl or less without the use of statin cholesterol-reducing drugs.

Oat bran is among my favorite ways to reduce LDL. Three tablespoons per day is a really effective method to drop your LDL around 20 points. There's twice the beta glucan (soluble, or "viscous", fiber)in oat bran, as compared to the more popular oatmeal. Add oat bran to anything you can think of: yogurt, cottage cheese, vegetarian chili, oatmeal, top desserts with it, etc. Some people struggle to find oat bran in the grocery store. Most health food stores that sell bulk products will have oat bran, usually less than a $1 per pound. Many grocery stores will also have an oat bran hot cereal along with the Cream of Wheat and oatmeal. That's okay, provided the only ingredient is oat bran--no added sugars, etc.

Another dynamite method to reduce LDL 10-20 points is adding raw almonds to your daily food choices. One or two handfuls per day works great. We find it at Sam's Club for around $12.99 for a 3 lb. bag. The plentiful fibers and monounsaturates in almonds keep you full and satisified, take the edge off your sweet tooth, and even blunt the blood sugar rise caused by other foods.

Both these foods are also great ways to combat the metabolic syndrome. Since both fiber-rich oat bran and almonds slow the release of sugars into the blood, blood insulin level is also reduced. This results in a happy cascade of less small LDL, increased HDL, and a reduction in inflammation.

All these wonderful effects contribute to inching you closer to success: dropping your heart scan score.

Pre-diabetes with normal blood sugar

20. July 2006 William Davis (0)

We pay special attention to pre-diabetes, in all its varied manifestations, in the Track Your Plaque program. This is because these factors are potent instigators of coronary plaque growth.

Early in the Track Your Plaque program we ignored these measures. After all, this is a program for heart disease risk reduction, not for mangement of diabetes. But we saw explosive rates of plaque growth when pre-diabetic factors were not controlled--even when cholesterol and related factors were under excellent control.

It became increasingly clear that factors associated with pre-diabetes needed to be managed, as well. This includes small LDL, increased blood sugar, high blood pressure, increased inflammation (as CRP).

Many people, however, have normal blood sugars (100 mg/dl or less) with a high blood insulin level (>10 microunits/ml). (This blood test is available in most laboratories.) This means that they have early resistance to insulin. The pancreas, the source of insulin, responds to the body's unresponsiveness to insulin by increasing insulin production.

Increased blood insulin with normal blood sugar will drive production of higher triglycerides, a drop in HDL, creation of small LDL, and inflammation--and coronary plaque growth, as evidenced by increasing CT heart scan score.

Blood insulin levels can be very effectively dropped by weight loss; exercise; reduction of processed carbohydrates like breads, pretzels, and breakfast cereals; and increased raw nuts and oat products; and vitamin D replacement to normal levels. Drug manufacturers are desperately trying to make this a mandate for drug treatment (Actos, Avandia), but are encountering resistance, since most people without overt diabetes don't want to take diabetic medication (rightly so!).

You and your doctor should consider insulin as a factor to track, especially if you have small LDL, low HSL, or high triglycerides, or any of the other manifestations listed above.

Sometimes small LDL is the only abnormality

19. July 2006 William Davis (0)

Janet is a 58-year old schoolteacher. At 5 ft 3 inches and 104 lbs, she had barely an ounce of fat on her size-2 body. For years, Janet's primary care physician complimented her on her cholesterol numbers: LDL cholesterol values ranging from 100 to 130 mg/dl; HDL cholesterol of 50-53 mg/dl.

Yet she had coronary disease. Her heart scan score: 195.

Lipoprotein analysis uncovered a single cause: small LDL. 95% of all of Janet's LDL particles were in the small category. What was surprising was that this pattern occurred despite her slender build. Weight is a powerful influence on the small LDL pattern and the majority of people with it are overweight to some degree. But not Janet.

How did she get small LDL if she was already at or below her ideal weight? Genetics. Among the genetic patterns that can account for this pattern is a defect of an enzyme called cholesteryl-ester transfer protein, or CETP. This is the exact step, by the way, that is blocked by torcetrapib, the new agent slated for release sometime in future (The manufacturer, Pfizer, is apparently going to sell this agent only packaged in the same tablet as Lipitor. This has triggered an enormous amount of criticism against the company and they are, as a result discussing marketing torcetrapib separately.)

Also note that Janet had a severe excess of small LDL despite an HDL in the "favorable" range. (See my earlier conversation on this issue, The Myth of Small LDL at http://drprevention.blogspot.com/2006/06/myth-of-small-ldl.html.)

With Janet, weight loss to reduce small LDL was not an option. So we advised her to take fish oil, 4000 mg per day; niacin, 1000 mg per day; vitamin D, 2000 units per day; use abundant oat bran and raw almonds, both of which suppress small LDL. This regimen has--surprisingly--only partially suppressed her small LDL pattern by a repeat lipoprotein analysis we just performed. We're hoping this may do it, i.e., stop progression or reduce her heart scan score.

The lesson: Small LDL is a very potent pattern that can be responsible for heart disease, even if it occurs in isolation. And, contrary to conventional thinking, small LDL can occur as an independent abnormality, even when HDL is at favorable levels.
