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 will also point to the lack of difference in LDL cholesterol among the three, since they cannot get beyond the fact that there’s more to coronary risk—a lot more—than LDL.


Off-the-shelf diets achieve off-the-shelf results

If you just need a T-shirt, a medium might fit fine. But if you’d like a nicely fitting suit or dress, then tailoring to your individual proportions is needed. When aiming towards maximizing benefits on lipoproteins and coronary risk, none of these diets achieve the kinds of changes we often need for coronary plaque reversal, as in the Track Your Plaque program. That requires making dietary changes that exert maximal effects on lipoprotein patterns.

Do I sell heart scans?

18. July 2008 William Davis (12)
I came across a criticism of the Track Your Plaque program recently that suggested that it was nothing more than a program to sell CT heart scans.

Huh?

I suppose if you say that the Track Your Plaque program is nothing more than a way to sell heart disease prevention, omega-3 fatty acids from fish oil, vitamin D, better nutrition, and better identification of causes of heart disease . . . well, I believe that would be true.

But is the program a "front" to sell heart scans?

No, it is not, nor has it ever been.

I've heard about these peculiar suspicions about the program before. Though I've never taken them seriously, let me clear up any lingering uncertainty:


--I have no relationship with any heart scan center, scanning facility, or hospital other than to interpret heart scans.

I do not own a scanner, I have no financial interest in a scanner or scanning center, nor have I ever had any interest. I also have no plans to do so in the future. Let business people in the imaging business do that. I want no part of it. I have seen what these people go through and, frankly, I want no part of it, nor do I want the appearance that I am advocating scans to make money. I'm accused of trying to make money from scans even when I do not have any financial interest!


--I do not sell heart scans or imaging packages, nor have I ever done so.

You can't buy a scan through Track Your Plaque, The Heart Scan Blog, or through me. To me, heart scans are simply a measuring tool to identify the extent of coronary plaque, as well as a tracking tool to follow its course. Without it, there would be no Track Your Plaque. But there is also no alternative. The closest alternative would be carotid intimal-medial thickness, a technique, while useful, is a distant second choice to indirectly gauge coronary plaque by examining the thickness of the carotid lining (not carotid plaque). Perhaps in 10 years, a better measure to gauge and track coronary plaque will emerge that has superior aspects over CT heart scanning. If reasonable, safe, accessible, and quantitative, then Track Your Plaque may adopt that technology as its measuring tool.

Track Your Plaque is not about heart scanning; Track Your Plaque is about measuring and tracking plaque that, in 2008, is still best accomplished with CT heart scans.


--I make loads of money from heart scans and Track Your Plaque.

Yeah, right.

Track Your Plaque is a volunteer venture for my team; none of us get paid a penny for doing all we do, including me. We charge a membership fee on the website (somewhere around $6-7 a month) to pay our expenses, such as code writing for our proprietary software (much of it remains under development), printing costs, modest legal costs, the costs of doing business (e.g., accountant). Despite the fact that Track Your Plaque and the Heart Scan Blog occupies a substantial part of the day of the Track Your Plaque team, none of us are reimbursed for our time. I do believe, however, that this concept is so enormously powerful that it will, someday, pay us all enough to allow us to devote more time and effort to it.

Personally, I can't wait to devote more time and effort to this concept that is simple, logical, and effective. More research is needed, more development is needed, more discussion is needed. Right now, it is all accomplished outside of our busy schedules, including my full-time cardiology practice. I continue to have 7 am procedures, middle-of-the-night calls, weekend hospital rounds and emergencies (though virtually none of these are the patients involved in prevention, but the "other" people: atrial fibrillation, elderly heart failure patients, rhythm disorders, cardiomyopathies, pulmonary hypertension, peripheral vascular disease, the non-compliant).


--The book, Track Your Plaque, is a gimmick to sell you a heart scan.

No, it's a program that relies on this technology. But there's no special deal, no discounts, no steering to heart scan centers that I have a special arrangement with. No such thing exists, nor has there ever been such an arrangement.


I've heard it all. Early on, when I was helping my friend, Steve Burlingame and his wife, Nancy, set up Milwaukee Heart Scan, I helped by providing medical oversite, education of physicians and public, and interpreting heart scans. After all, in the "early days," nobody knew anything about heart scans. It was a long, hard climb against ignorance, habit, entrenched thinking, stubbornness, and stupidity. I've been paid next to nothing for all this. I told Steve long ago that, given the extraordinary expenses of maintaining an independent scanning center, that he should first pay his expenses, pay his technologists, receptionists, and nurse, pay himself, then pay me for reading scans if he had any money left over. Most of the time, Steve had nothing left over and I was paid nothing.

So, while some of my colleagues were assuming that I was rolling in money from "promoting" heart scans, the reality was that I was doing nearly everything for free. (It certainly wasn't the high life I was living; I don't drive a Mercedes, take fancy vacations, none of that. In fact, I work about 51 weeks a year.)

Why do I do this if it doesn't yield a big flow of money? Because I believe in it as a superior path to the conventional. If I were simply interested in making more money--I wouldn't do it. I would simply do what all my cardiology colleagues are doing: more heart catheterizations, more angioplasties and stents, learning how to do carotid stents, iliac stents, peripheral angioplasty, renal stents, acquiring the skills to put in defibrillators, new device insertion like umbrellas in the interatrial septum, etc. There's plenty more money in that. It's also not that hard. I know, because that is my background: high-risk cardiac interventions. That's what I was trained to do, that's what I did from a number years, until I started to see that this was nothing more than "putting out fires" in people who became increasingly ill and reliant on bail-out procedures. It makes lots of money, but it is also fundamentally wrong.

So, no, I do not sell heart scans, nor is the Track Your Plaque program or The Heart Scan Blog meant to promote heart scans except as a tool for tracking this disease.

That's it, pure and simple.

Plaque is the new cholesterol

17. July 2008 William Davis (3)
Which is more important: cholesterol or coronary plaque?

Ask what Dr. Michael Eades' calls "statinators," and you will likely receive a befuddled look. Or, you might receive comments like "Measuring plaque has never been shown to reduce mortality."

While risk factors for heart disease are important, no doubt (my office practice is about half lipid consultation and complex hyperlipidemia management), for many they have become an end in themselves. In other words, LDL cholesterol in particular dominates thinking so much that it has caused many to exclude the fact that plaque---coronary atherosclerotic plaque---is the disease itself.

Dozens of studies, from the St. Francis Heart Study to the 25,000-participant UCLA registry, to the recently-released MESA database (ethic differences, women, as well as superiority to carotid measures) have repeatedly shown that heart scan scores (coronary artery calcium scores) are superior to conventional risk factors (usually via the Framingham risk score) for predicting future heart attack and other events. And the differences are not minor incremental differences. The predictive power of plaque measurement via heart scanning is multiples better: 4 times, 10 times, 20 times or more in various subgroups.

Much of what we do in medicine is not based on long-term studies of outcome, pitting some diagnostic measure or treatment against placebo. It is already standard practice to measure plaque via heart catheterization, crudely via stress testing, and increasingly popular CT coronary angiography. None of these methods have been subjected to studies comparing testing vs. not testing in a large population, followed by some program of prevention to assess differences in mortality, heart attack, and other events.

Why should heart scan be held to such a standard?

Dr. Scott Grundy, lipid guru and one of the experts who sat on the Adult Treatment Panel-II for lipid management guidelines, recently stated [emphasis added]:

"Imaging has at least 3 virtues. It individualizes risk assessment beyond use of age, which is a less reliable surrogate for atherosclerosis burden; it provides an integrated assessment of the lifetime exposure to risk factors; and it identifies individuals who are susceptible to developing atherosclerosis beyond established risk factors. Also of importance, in the absence of detectable atherosclerosis, short-term risk appears to be very low."

Well said, and from a vocal statinator, to boot.

Sadly, Dr. Grundy goes on to say how plaque imaging can serve to better determine who will benefit from statin drug use.

Of course, you and I know that there is far more to reduction of cardiovascular risk applied to a framework of serial plaque quantification ("tracking plaque"!) than statin drugs. I doubt that a man as intelligent as Dr. Grundy truly believes this. I suspect that he is simply stating what he knows what will be published without resistance in the standard medical literature, trying to achieve a modest incremental success just by raising consciousness about heart scanning and plaque imaging: first things first.

Maybe next will be a plaque-tracking, or even a plaque-reducing, mainstream conversation, just like the one we've been conducting for the past four years.

Track Your Plaque success story blows it

17. July 2008 William Davis (3)
Joe was a Track Your Plaque Success Story. With a starting heart scan score of 278, he dropped it 12 months later to 264, a 5% reduction. Though not a huge reduction, Joe's risk for a heart attack or other coronary event was virtually zero. I was very proud of Joe.

Among the culprit lipoprotein patterns that caused Joe's plaque was lipoprotein(a), or Lp(a). Niacin was therefore crucial to his program. It was among the principal reasons he dropped his heart scan score and reduced his risk for heart attack so dramatically.

Since he retired, Joe has been freewheeling around the country, traveling and having a great time. He consequently stopped thinking about his heart disease and Lp(a). He also tired of the occasional hot flushes he'd experienced with niacin. Though the flushes were promptly aborted by drinking two glasses of water, he simply didn't want to be bothered.

So when Joe saw this interesting and tantalizing "flush-free niacin" on the store shelf, he grabbed it.

Joe came back to the office. His blood pressure was 190/94, so high that he was having occasional chest pains from it (which can happen when something called "left ventricular diastolic dysfunction" develops from hypertension). His lipoprotein patterns were terrible, including a big upward jump in Lp(a) and drop in HDL. So I asked him to have another heart scan right away: Score 371, a 40% increase. In other words, his program went down the toilet.

Why?

Simple: Flush-free niacin. I've said it before (No flush = No effect and No flush niacin kills) and I'll say it again:

Flush-free or No-flush niacin is a complete, unadulterated, completely ineffective SCAM.

Flush-free or no-flush niacin is not a substitute for niacin. Joe is yet another example of how dangerous this scam can be. It turned one of our great success stories into a failure.

Please, please, please do not fall for this misleading and potentially dangerous scam product. While the product itself is not intrinsically dangerous, it denies you the benefits of the real thing: niacin.

Thankfully, the mistake in Joe's program was caught before a heart attack or other catastrophe. He did manage to pass a stress test, though with a flagrantly out-of-control blood pressure response. We'll get him back on track--but with niacin, the real thing.

Increased blood calcium and vitamin D

21. June 2010 William Davis (50)
Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

Heart health consultation with Dr. Joe D. Goldstrich

20. June 2010 William Davis (3)
Cardiologist, nutritionist, and lipidologist, Dr. Joe D. Goldstrich, is a frequent contributor to the Track Your Plaque Forum, where we discuss the full range of issues relevant to coronary health and coronary plaque reversal.

I have come to value Dr. Goldstrich's unique insights, especially in nutrition. Formerly National Director of Education and Community Programs for the American Heart Association and a physician at the Pritikin Center, his dietary philosophy has evolved away from low-fat and towards a low-carbohydrate focus, much as we use in Track Your Plaque. Like TYP, Dr. Goldstrich is always searching for better answers to gain control over coronary health. His unique blend of ideas and background has helped us craft new ideas and strategies. Dr. Goldstrich has proven especially adept at understanding how to incorporate new findings from clinical studies in our framework of coronary atherosclerotic plaque management strategies.

Dr. Goldstrich is offering to share his expertise with our online community. If you would like a one-on-one phone consultation with Dr. Goldstrich, you can arrange to speak with him at his HealthyHeartConsultant.com website.

Wheat aftermath

16. June 2010 William Davis (18)
Following my 4 oz whole wheat misadventure that yielded the sky-high blood sugar of 167 mg/dl, compared to einkorn wheat's 110 mg/dl, I suffered through a 36-hour period of misery.

After I obtained the blood sugar of 167 mg/dl, I biked hard for one hour. This yielded a blood sugar back down in the 80s. I felt spacey in the ensuing few hours, as well as a little queasy. However, about 12 hours later, I awoke with overwhelming nausea along with that hypersalivating thing that happens just prior to vomiting. It did not come to that, but persisted all through the following day.

The next morning, I could barely concentrate. Trying to read a study (admittedly on the complex topic of agricultural genetics), I had to read each paragraph 4 or 5 times. Abdominal cramps and a bloated feeling also developed, though I was able to eat.

The 2nd night was filled with incredibly vivid dreams and intermittent sleeplessless. I awoke about 5 times through the night, but periods of sleep were filled with detailed, colorful dreams. I dreamt that a large corporation was secretly trying to gain control over the world's water supply, and I snuck onto a complex underwater vessel that was exploring and mapping the coastline of the Great Lakes in preparation. Weird.

I recognized these odd feelings as various facets of wheat intolerance, since they were all reminiscent of feelings I used to experience before I removed wheat from my diet. They were amplified and compressed, likely because I had been wheat-free for so long.

The odd thing is that, despite the modest blood sugar effect of my einkorn experience, none of the gastrointestinal or neurologic effects of wheat developed. So far, two other people with acute gastrointestinal wheat sensitivities have consumed our einkorn bread, also without reproduction of their usual symptoms.

Einkorn contains gluten, though the structure of the many gluten proteins of einkorn differs from that of the wheat bread I consumed, an example of modern Triticum aestivum. 14-chromosome einkorn carries what biologists call the "A" genome, while Triticum aestivum has the combines genomes of 3 plants, the combination of the A, B, and D genomes. It is the D genome that contains the genes coding for the most obnoxious, immunogenic forms of gluten.

So einkorn may not be entirely benign, but it is a good deal less obnoxious than modern Triticum aestivum.

I am awaiting the reports from a few other people on their experiences.

In search of wheat: Einkorn and blood sugar

14. June 2010 William Davis (32)
There are three basic aspects of wheat's adverse health effects: immune activation (e.g., celiac disease), neurologic implications (e.g., schizophrenia and ADHD), and blood sugar effects.

Among the questions I'd like answered is whether ancient wheat, such as the einkorn grain I obtained from Eli Rogosa, triggers blood sugar like modern wheat.

So I conducted a simple experiment on myself. On an empty stomach, I ate 4 oz of einkorn bread. On another occasion I ate 4 oz of bread that dietitian, Margaret Pfeiffer, made with whole wheat flour bought at the grocery store. Both flours were finely ground and nothing was added beyond water, yeast, olive oil, and a touch of salt.

Here's what happened:

Einkorn wheat bread:

Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 110 mg/dl

Conventional wheat bread
Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 167 mg/dl

The difference shocked me. I expected a difference between the two, but not that much.

After the conventional wheat, I also felt weird: a little queasy, some acid in the back of my throat, a little spacey. I biked for an hour solid to reduce my blood sugar back to its starting level.

I'm awaiting the experiences of others, but I'm tantalized by the possibility that, while einkorn is still a source of carbohydrates, perhaps it is one of an entirely different variety than modern Triticum aestivum wheat. The striking difference in blood sugar effects make me wonder if einkorn eaten in small quantities can keep us below the Advanced Glycation End-Product threshold.
 

In search of wheat: We bake einkorn bread

12. June 2010 William Davis (6)
With the assistance of dietitian and health educator, Margaret Pfeiffer,MS RD CD, author of Smart 4 Your Heart and very capable chef and breadmaker (previously, before she gave up wheat), we made a loaf of bread using Eli Rogosa's einkorn wheat. Recall that einkorn wheat is the primordial 14-chromosome wheat similar to the wild wheat harvested by Neolithic humans and eaten as porridge.

The essential question: Has wheat always been bad for humans or have the thousands of hybridization experiments of the last 50 years changed the structure of gluten and other proteins in Triticum aestivum and turned the "staff of life" into poison? I turn to einkorn wheat, the "original" wheat unaltered by human manipulations, to figure this out. While einkorn wheat is still a source of carbohydrates, is it something we might indulge in once in a while without triggering the adverse phenomena associated with modern wheat?   

Here's what we did:

This is the einkorn grain as we received it from Eli's farm. This was enough to make one loaf (approximately 3 cups).











The einkorn grain is a dark golden color. I tried chewing them. They taste slightly nutty. They soften as they sit in your mouth.





Here's Margaret putting the einkorn grain into the electric grinder.









We tried to grind the grain by hand with mortar and pestle, but this proved far more laborious than I anticipated. After about 15 minutes of grinding, this is what I got:



Barely 2 tablespoons. That's when Margaret fired up the electric grinder. (I can't imagine having to grind up enough flour by hand for an entire family. Perhaps that's why ancient cultures were thin despite eating wheat. They were just exhausted!)

We added water, salt, and yeast, then put the mix into an electric breadmaker to knead the dough and keep it warm.

We let the dough rise for 90 minutes, much longer than conventional dough. The einkorn dough "rose" very little. Margaret tells me that most dough made with conventional flour rises to double its size. The einkorn dough increased no more than 20-30%.

The einkorn dough also distinctly smelled like peanut butter.





After rising, we baked the dough at 350 degrees F for 30 minutes. This is the final product.

Because I want to gauge health effects, not taste, the bread we made had no added sugar or anything else to modify taste or physiologic effect.

On first tasting, the einkorn bread is mildly nutty and heavy. It had an unusual sour or astringent taste at the end, but overall tasted quite good.

Next: What happens when we eat it? I'm going to give the einkorn bread (I've got to make some more) to people who experience acute reactions to conventional wheat and see if the einkorn does the same. I will also assess blood sugar effects since, after all, hybridizations or no, it is still a carbohydrate.



Margaret Pfeiffer's book is available on Amazon:

Ezekiel said what?

10. June 2010 William Davis (24)
Some people are reluctant to give up wheat because it is talked about in the Bible. But the wheat of the Bible is not the same as the wheat of today. (See In search of wheat and Emmer, einkorn and agribusiness.) Comparing einkorn to modern wheat, for example, means a difference of chromosome number (14 chromosomes in einkorn vs. 42 chromosomes in modern strains of Triticum aestivum), thousands of genes, and differing gluten content and structure.

How about Ezekiel bread, the sprouted wheat bread that is purported to be based on a "recipe" articulated in the Bible?

Despite the claims of lower glycemic index, we've had bad experiences with this product, with triggering of high blood sugars, small LDL, and triglycerides not much different from conventional bread.

David Rostollan of Health for Life sent me this interesting perspective on Ezekiel bread from an article he wrote about wheat and the Bible. David argues that the entire concept of Ezekiel bread is based on a flawed interpretation.

"I Want to Eat the Food in the Bible."


Are you sure about that?

Some people, still wanting to be faithful to the Bible, will discard the "no grain/wheat" message on the basis of biblical example. After all, God told Ezekiel to make bread, he gave the Israelites "bread from heaven," and then Jesus (who is called the "Bread of Life"!) multiplied bread, and even instituted the New Covenant with what? Bread and wine! If you're going to live the Bible, it seems that bread and/or wheat is going to play a part.

But this is unnecessary. Sure, the Bible can and does tell us how to live, but this doesn't mean that everything in the Bible is meant to be copied verbatim. Applying the Bible to our lives requires wisdom, not a Xerox machine.

The Bible was written in a historical context, and the setting happened to be an agricultural one. Because of this, the language used to describe blessing spoke of things like fields full of grain, or barns overflowing with wheat. Had the Bible been written in the context of a hunter-gatherer culture, the language describing blessing probably would have been about the abundance of wild game, or baskets full of vegetables. Whatever is most valuable in your time and in your culture is a blessing. God accommodated His message to the culture as it existed at the time. This is done throughout Scripture.

There is a danger, then, in merely copying what the Bible says, instead of extracting the principles by which to live. Take the above example of Ezekiel, for instance. There's a whole product line in health food stores called "Ezekiel Bread" that supposedly copies the recipe given in Ezekiel 4:9. This is from the website:

"Inspired by the Holy Scripture verse Ezekiel 4:9., 'Take also unto thee Wheat, and Barley, and beans, and lentils, and millet, and Spelt, and put them in one vessel, and make bread of it...'"

Believing that this "recipe" has some kind of special power just because it's in the Bible is ridiculous. How ridiculous is it? I'll tell you in a moment, but first let me say that this is why it's so important not to confuse descriptives with prescriptives. Is the Bible telling a story, or is it telling us to do something? We would be well-advised not to confuse the two.

In the case of the Ezekiel Bread, what is going on in the passage? There's a siege going on, with impending famine, and Ezekiel is consigned to eating what was considered back then to be some of the worst possible food. It was basically animal chow. But that's not the worst thing going on in this passage. Apparently, when the makers of Ezekiel Bread were gleaning their inspiration for the perfect recipe, they stopped short
of verse 12:

"And thou shalt eat it as barley cakes, and thou shalt bake it with dung that cometh out of man, in their sight."

Um...what? Well, there was a good reason for this. God was judging His people, and by polluting this really bad bread with dung (which was a violation of Mosaic law; Lev. 5:3), He was saying that they were no different from the unclean Gentiles.

So why would we take this story and extrapolate a bread recipe from it? Beats me. If you were going to be consistent, though, here's what you'd have to end up with:



Let that be a lesson to you. We don't just go and do everything that we see in the Bible.

Low-carb gynecologist

6. June 2010 William Davis (36)
I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March.

Dr. Fox is quiet and unassuming, but had incredible things to say about his experience with carbohydrate restriction in female infertility and pregnancy. While readers of The Heart Scan Blog already know that I advocate a diet free of wheat, cornstarch, and sugar for heart health and correction of multiple lipoprotein abnormalities, it was fascinating to hear how a similar approach seems to yield extraordinary benefits in this entirely unrelated area of female health. Obviously, female infertility and pregnancy are unrelated to heart health, but the extraordinary benefits witnessed by Dr. Fox in this area suggest that some fundamental lessons in human physiology can be learned. The results are so incredible that we are all sure to hear more about this approach as experience grows.

So I tracked Dr. Fox down in his busy Jacksonville, Florida practice to fill us in on some details.

WD: Dr. Fox, could you tell us something about yourself and what led you to use carbohydrate restriction in your female patients?

MF: I have been in practice as a reproductive endocrinologist for 15 years. During that time, I have seen our specialty move from a broad based practice of reproductive endocrinology to a narrow IVF [in vitro fertilization] focus, with patients being pushed through IVF in a cookie-cutter fashion without any emphasis on non-medical therapy.

Our focus has been to remain as a broad practice where we individualize care and attempt in every case to achieve pregnancy short of IVF. Five years ago, this continued quest for better care led us into the insulin resistance, low-carbohydrate metabolic world that has transformed our practice, although our practice offers all aspects of reproductive endocrinology including sub-specialized minimally invasive surgery, and all available infertility options.


WD: I have been intrigued by your comments about improved fertility with the low-carb diet. Could you elaborate on this?

MF: Yes, five years ago, as more information regarding Polycystic Ovarian Disease or Syndrome (PCOD/S) and its relationship to insulin resistance (high insulin levels) was emerging, we had a simple realization. As we've known for some time, insulin stimulates excess male hormone levels in the ovary, which disrupts ovulation and fertility. Then our job was to lower or virtually eliminate high insulin levels. Again, in simple fashion, we looked at physiology and realized that insulin is released only in response to dietary carbohydrates. Thus, elimination of carbohydrates should resolve the problem. This, in fact, is the effect that we have seen.

In our previous approaches to PCOD, we utilized oral ovulation medicines generating pregnancy rates in the 40% range overall. Now, with the nutritional approach, for those patients that follow our recommendations, our pregnancy rates are over 90%! This has dramatically reduced the need for in vitro fertilization in these patients.

To extend this idea further, we first started with relative low-carbohydrate diets, such as the South Beach diet, but quickly realized this didn't produce a metabolic effect. Over time, it has borne out that only the very low-carbohydrate diet (VLCD) approach produces significant metabolic change. Our impression then was that the current U.S. nutritional exposure probably increases insulin levels and that this has a detrimental effect on fertility.

To counter this effect, we now recommend the VLCD to all fertility patients and their spouses. The pregnancy rates do seem much better overall, as well as seeing a reduction in miscarriage rates. For the first time at our national meeting last year, there were three articles that showed improved pregnancy rates in patients without PCOD or insulin resistance in IVF when Glucophage was used. This drug decreases insulin. This supports the idea that our entire population is subjected to fertility-reducing high-carbohydrate diet.

WD: Do you see any other changes in these patients on the diet?

MF: Yes. All metabolic parameters, as well as many common complaints, improve. Cholesterol and triglyceride levels improve, while "good" HDL cholesterol levels increase. Weight drops at a pace of 12 lbs per month very steadily and we have many many patients who have experienced 50lb wt loss. Blood pressure decreases steadily in these patients and we are often able to get them off of cholesterol and blood pressure medicines. Common symptoms such as anxiety, sleep disturbances, decreased energy, migraine headaches and depression all dramatically improve. Again we can often get patients off depression and migraine suppression medications. So this approach helps in a multitude of areas.



WD: I was also interested in hearing more about your experience with morning sickness and the effects of a low-carb diet. Could you tell us more about this? Also, any thoughts on why this happens?

MF: As we continued to expand our thoughts about VLCD and fertility/pregnancy, we began to extend the nutritional approach into pregnancy. We know that pregnancy hormones dramatically worsen insulin resistance that is responsible for the condition, gestational diabetes. If insulin resistance is worsened, then reactive hypoglycemia is worsened. One of the biggest symptoms of hypoglycemia is nausea. So, in response to this, we have counseled our patients on the diet in pregnancy and have found a dramatic reduction in nausea. We recommend snacking every two hours in pregnancy.

The other "traditional" issue in pregnancy are cravings. These also likely stem from hypoglycemia. I have had many husbands tell us later that their wives, in contrast to friends etc, were calm and not moody or anxious during their pregnancies. Hypoglycemia probably is a serious issue for the fetus as well and may be the "signal" that turns on the insulin-resistant gene. Many theorists feel this might be an activated gene during the pregnancy.


WD: Do you use any unique approaches to the low-carbohydrate approach, e.g., inclusion of dairy, meal frequency, "induction" strategies (i.e., induction to the diet, not of labor!), etc.?

MF: Yes. As I'm sure everyone who works in the VLCD world does, we also have some tricks to make this work better. My biggest push, although hard to get patients to agree, is to see a counselor along with our follow-up in order to deal with "addictive behaviors" and "stress eating" that so many of our patients relate to us. Good stress management and cognitive behavioral therapy go a long way in helping this become a permanent change.

We also really push frequent calorie intake or "snacking." I think again that hypoglycemia produces an inborn drive to "cure" or "fix" starvation and leads to dramatic overeating. We have a short list of snacks that we recommend. The concept of hunger is offered as a failure of the program. We aim to eliminate hunger, as it represents hypoglycemia. The analogy I use is, if you drove your car until you ran out of gas before you ever sought to find gas, your life would be miserable. So it is the same with your metabolic engine: If you let it run out, the measures your system takes to fix it are very detrimental to life and certainly to nutritional health.

Our other big push is fat. People can wrap themselves around protein and vegetables, but they totally miss the high-fat (animal fat) part of the conversation. We have to really push that aspect. In regards to dairy, we allow for non-processed cheeses and minimal milk. An alternative is to mix about 4 oz whole milk with 4 oz of heavy whipping and 4 oz of water to create a "milk" with less sugar. Similarly, shakes and smoothies can be made with heavy whipping cream with pure whey protein powder added to create a liquid meal for those who "don't have time" to cook.


WD: Thanks, Dr. Fox. We look forward to hearing more about your approach in future.

Track Your Plaque reduces healthcare costs 35%

29. May 2010 William Davis (12)
Allow me to wear my Track Your Plaque hat for this post.

Mr. Richard Rawle is CEO of Utah company, Tosh, Inc. Mr. Rawle has been an avid follower of the Track Your Plaque program and has introduced the program to company employees. Here's what he has to say about the experience:

“Our company has been utilizing the principles of TYP [Track Your Plaque] for over a year and has experienced great results that have positively impacted the lives of our employees and our health care costs.

Since we began our wellness program, we have presented the TYP diet and lifestyle guidelines to all of our employees and their families. Although the overwhelming majority of our employees do not have cardiovascular issues, the preventative nature of TYP is too important not to be utilized. The TYP principles along with our increased focus on healthy living have already changed our group’s blood chemistry. HDL levels in particular have increased significantly and resulted in a large percentage of our employees having HDL levels of 60 or higher. Vitamin D levels have substantially increased and LDL levels have significantly decreased in the majority of our employees. Subsequently, in the 12 months just ended, our health care costs are some 35% less than other groups of comparable size and age.

I believe the TYP program has been an integral part of the success of our company's vast improvement in employee health/wellness, resulting in significant health care cost reductions."

Richard Rawle
CEO Tosh Inc.

Track Your Plaque saves lives. Track Your Plaque also saves money . . . lots of it. Despite the upfront costs of some additional blood testing and a heart scan, the dramatic reduction in need for medications, reduced heart attack, diabetes, and many other chronic conditions add up to a huge cost savings, much as Tosh, Inc. employees have enjoyed.

The Federal government has been looking towards large hospital systems to lead the way in healthcare delivery, systems that employ their physicians and possess economies of scale. But I say the answer to reducing healthcare costs will NEVER be found in hospital systems. Healthcare cost savings will be realized by delivering truly effective health solutions directly to people themselves, much as we do in Track Your Plaque.

In search of wheat

26. May 2010 William Davis (43)
Many people ask: "How can wheat be bad if it's in the Bible?"

Wheat is indeed mentioned many times in the Bible, sometimes literally as bread, sometimes metaphorically for times of plenty or freedom from starvation. Moses declared the Promised Land "a land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey" (Deuteronomy 8:8).

Wheat is a fixture of religious ceremony: sacramental bread in the Eucharist of the Christian church, the host of the Holy Communion in the Catholic church, matzoh for Jewish Passover, barbari and sangak are often part of Muslim ritual. Wheat products have played such roles for millenia.

So how can wheat be bad?

What we call wheat today is quite different from the wheat of Biblical times. Emmer and einkorn wheat were the original grains harvested from wild growths, then cultivated. Triticum aestivum, the natural hybrid of emmer and goatgrass, also entered the picture, gradually replacing emmer and einkorn.

The 25,000+ wheat strains now populating the farmlands of the world are considerably different from the bread wheat of Egyptians, different in gluten content, different in gluten structure, different in dozens of other non-gluten proteins, different in carbohydrate content. Modern wheat has been hybridized, introgressed, and back-bred to increase yield, make a shorter stalk in order to hold up to greater seed yield, along with many other characteristics. Much of the genetic work to create modern wheat strains are well-intended to feed the world, as well as to provide patent-protected seeds for agribusiness.

What is not clear to me is whether original emmer, einkorn, and Triticum aestivum share the adverse health effects of modern wheat.

Make no mistake about it: Modern wheat underlies an incredible range of modern illnesses. But do these primitive wheats, especially the granddaddy of them all, einkorn, also share these effects or is it a safe alternative--if you can get it?

I've ordered 2 lb of einkorn grain, unground, from Massachusetts organic farmer, Eli Rogosa, who obtained einkorn seed from the Golan Heights in the Middle East. We will be hand-grinding the wheat and making einkorn bread. We will eat it and see what happens.

Super-carbohydrate

22. May 2010 William Davis (18)
Wheat starches are composed of polymers (repeating chains) of the sugar, glucose. 75% of wheat carbohydrate is the chain of branching glucose units, amylopectin, and 25% is the linear chain of glucose units, amylose.

Both amylopectin and amylose are digested by the salivary and stomach enzyme, amylase, in the human gastrointestinal tract. Amylopectin is more efficiently digested to glucose, while amylose is less efficiently digested, some of it making its way to the colon undigested.

Amylopectin is therefore the “complex carbohydrate” in wheat that is most closely linked to its blood sugar-increasing effect. But not all amylopectin is created equal. The structure of amylopectin varies depending on its source, differing in its branching structure and thereby efficiency of amylase accessibility.

Legumes like kidney beans contain amylopectin C, the least digestible—hence the gas characteristic of beans, since undigested amylopectin fragments make their way to the colon, whereupon colonic bacteria feast on the undigested starches and generate gas, making the sugars unavailable for you to absorb.

Amylopectin B is the form found in bananas and potatoes and, while more digestible than bean amylopectin C, still resists digestion to some degree.

The most digestible is amylopectin A, the form found in wheat. Because it is the most readily digested by amylase, it is the form that most enthusiastically increases blood sugar. This explains why, gram for gram, wheat increases blood sugar to a much greater degree than, say, chickpeas.

The amylopectin A of wheat products, “complex” or no, might be regarded as a super-carbohydrate, a form of highly digestible carbohydrate that is more efficiently converted to blood sugar than nearly all other carbohydrate foods.

Are you hungry?

6. December 2011 William Davis (43)
Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

 

Chocolate . . . for adults only

30. November 2011 William Davis (22)
If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.
I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

19. November 2011 William Davis (29)
At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

14. November 2011 William Davis (73)
More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Lessons from the 20-year statin experience

2. November 2011 William Davis (0)
Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages.

Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:

Small LDL particles and increased HbA1c--An evil duo

30. October 2011 William Davis (53)
Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

Unforgiving small LDL particles

21. October 2011 William Davis (39)
Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.

A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.

In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particle

Blast triglycerides

15. May 2009 William Davis (0)
The conventional answers to high triglycerides levels are generally: low-fat diet, a fibrate drug (Tricor, Lopid), a statin drug, and--most recently--prescription fish oil.

This is the regimen to take if you want the drug industry to get even richer and more powerful than they already are. After all, what CEO of a pharmaceutical company can stand to have his salary and benefits slashed to below $200 million this year? It's outrageous!

If you really want to blast the heck out of your triglycerides and achieve numbers like 50 mg/dl, then the regimen to consider consists of:

--Elimination of sugars, wheat, and cornstarch
--Fish oil--Sam's Club would do fine at $8 for 350 capsules, or the high-potency at $14.99 for 180 capsules (at 680 mg EPA +DHA, nearly the same potency as prescription Lovaza at 842 mg)
--Vitamin D supplementation sufficient to achieve normal blood levels (60-70 ng/ml)

Those three strategies alone can reduce triglycerides far more than any drug combination. In fact, it is rare for someone with triglycerides as high as 900 mg/dl to not reduce them to the <100 mg/dl range.

Cheerios: Prescription required?

13. May 2009 William Davis (15)
Followers of The Heart Scan Blog know my feelings about Cheerios:


Can you say "sugar"?

Cheerios and heart health


There's an interesting tussle going on between the makers of Cheerios, General Mills, and the FDA.

The FDA says that the Cheerios' package claims of:

• "you can Lower Your Cholesterol 4% in 6 weeks"
• "Did you know that in just 6 weeks Cheerios can reduce bad cholesterol by an average of 4 percent? Cheerios is ... clinically proven to lower cholesterol. A clinical study showed that eating two 1 1/2 cup servings daily of Cheerios cereal reduced bad cholesterol when eaten as part of a diet low in saturated fat and cholesterol."

constitute a medical claim, i.e., trying to promote Cheerios as a drug.

I'm glad that the FDA has come down on General Mills. But I find this entire episode laughable: The debate is over the purported health benefits of what I would regard as pure junk food, no better in my view than claiming that a cupcake has health benefits, or a carton of ice cream.

In my experience, Cheerios does not 1) reduce risk for heart disease, nor 2) reduce cholesterol.

It does, however, cause blood sugar to skyrocket and increase the small type of LDL--you know, the type that causes heart disease.

"Placebos are frequently of value"

12. May 2009 William Davis (1)
The treatment of angina pectoris, generally speaking, is unsatisfactory.

Any procedure that relieves mental tension is valuable. Since patients suffer particularly during the winter, I encourage winter vacations in a southern climate.

I insist that obese patients lose weight, and have found small doses of benzedrine, 10 to 20 mg. daily, helpful in curbing the appetite.

I generally forbid smoking. This is a particularly disturbing task for many patients to carry out. In such cases, I suggest that 3 or 4 cigarettes be smoked daily, knowing full well that regardless of what I say or recommend, the patients is going to continue to smoke.

Innumerable drugs, most of which are of questionable value, have been used to prevent attacks of angina pectoris. In fact, placebos are frequently of value.

Testosterone--The male sex hormone has been effective in my experience. Whether it acts as a vasodilator or merely by promoting a sense of well-being is not known.

Alcohol--Alcohol (whiskey, brandy, rum) has been used for many years in the treatment of angina pectoris. I have prescribed it in moderate quantity--an ounce several times a day--and while I have not made alcoholics of any of my patients, I also have not cured any of them with it. Preparations, such as creme de menthe, are of value in relieving "gas" of which so many patients complain.

Iodine is not salt

12. May 2009 William Davis (3)
I've noticed a point of confusion recently, something I hadn't noticed in my patients before: Because of the public health advice from the FDA, American Heart Association, and Surgeon General's office to reduce sodium/salt intake, people have thought this meant reducing iodine, too.

I believe that people have drawn an equation in their minds:


Sodium = iodine


Of course, they are two entirely unrelated things.

Recall that the only reason iodine is added to many (not all) salt products is because it was a public health solution to solve the substantial nationwide iodine deficiency prevalent during the 20th century. But it was a solution conceived in 1924, when the FDA thought this was the best way to get iodine into Americans. And it worked.

Unfortunately, sodium does indeed present adverse effects in some people. As a result, "get your iodine from salt" has evolved into "reduce your sodium intake." Everyone forgot about the iodine: They forgot about the large disfiguring goiters, the poor school performance in iodine-deficient schoolchildren, the mentally-impaired offspring of iodine-deficient mothers.

So don't confuse sodium with iodine. You may need less of the former, but more of the latter.

For more on this, see "Help keep your family goiter free."

"You can't reduce coronary plaque"

10. May 2009 William Davis (9)
"I told my cardiologst that I stumbled on a program called 'Track Your Plaque' that claims to be able to help reduce your coronary calcium score.

"My cardiologist said, 'That's impossible. You cannot reduce coronary plaque. I've never seen anyone reduce a heart scan score."

Who's right here?

The commenter is right; the cardiologist is wrong.

I would predict that the cardiologist is among the conventionally-thinking, "statins drugs are the only solution" group who follows his patients over the years to determine when a procedure is finally "needed." In fact, I know many of these cardiologists personally. The primary care physicians are completely in the dark, usually expressing an attitude of helplessness and submitting to the "wisdom" of their cardiology consultants.

Quantify and work to reduce the atherosclerotic plaque? No way! That's work, requires thinking, some sophisticated testing (like lipoprotein testing), even some new ideas like vitamin D. "They didn't teach that to me in medical school (back in 1980)!"

Welcome to the new age.

Atherosclerotic plaque is 1) measurable, 2) trackable, and 3) can be reduced.

We do it all the time. (Amy still holds our record: 63% reduction in plaque/heart scan score.)

Though I pooh-pooh the value of statin drug studies, there's even data from the conventional statin world documenting coronary plaque reversal. The ASTEROID Trial of rosuvastatin (Crestor), 40 mg per day for one year, demonstrated 7% reduction of atherosclerotic plaque using intracoronary ultrasound.

I have NEVER seen a heart attack or appearance of heart symptoms (angina, unstable angina) in a person who has reversed coronary plaque (unless, of course, they pitched the whole effort and returned to bad habits--that has happened). Stick to the program and coronary risk, for all practical purposes, been eliminated.

A heart scan score is not a death sentence. It is simply a tool to empower your prevention program, a measuring stick to gauge plaque progression, stabilization, or regression. Don't accept anything less.

Lethal lipids

8. May 2009 William Davis (15)
There's a specific combination of lipids/lipoproteins that confers especially high risk for heart disease. That combination is:

Low HDL--generally less than 50 mg/dl

Small LDL--especially if 50% or more of total LDL

Lipoprotein(a)--an aggressive risk factor by itself


This combination is a virtual guarantee for heart disease, often at a young age. It's not clear whether each risk factor exerts its own brand of undesirable effect, or whether the combined presence of each cause some adverse interaction.

For instance, lipoprotein(a), or Lp(a), by itself is the most aggressive risk factor known (that nobody's heard about--there's no blockbuster revenue-generating drug for it). Each Lp(a) molecule is a combination of an LDL cholesterol molecule with a specific genetically-determined protein, apoprotein(a). If the LDL component of Lp(a) is small, then the combination of Lp(a) with small LDL is somehow much worse, kind of like the two neighborhood kids who are naughty on their own, but really bad when they're together.

Interestingly, the evil trio responds as a whole to many of the same corrective treatments:

Niacin--increases HDL, reduces small LDL, and reduces Lp(a)

Elimination of wheat, cornstarch, and sugars--Best for reducing small LDL; less potent for Lp(a) reduction.

High-fat intake--Like niacin, effective for all three.

High-dose fish oil--Higher doses of EPA + DHA north of 3000 mg per day also can positively affect all three, especially Lp(a).


If you have this combination, it ought to be taken very seriously. Don't let anybody tell you that it is uncorrectable--just because there may be no big revenue-generating drug to treat it on TV does not mean that there aren't effective treatments for it. In fact, some of our biggest successes in reducing heart scan scores have had this precise combination.

"Get regressive"

6. May 2009 William Davis (0)
This caught my eye:



Niaspan, prescription niacin, now sold by Abbott Laboratories, is now promoting its advantages in regressing coronary plaque:



In patients with a history of coronary artery disease (CAD) and hypercholesetgerolemia, Niaspan (niacin), in combination with a bile acid-binding resin, is indicated to slow progression or promote regression of atherosclerotic disease.



And the new slogan: "Get regressive."



Interestingly, the new marketing campaign is based on relatively old data. They base this new claim on 3 studies:



1) Cholesterol-Lowering Atherosclerosis Study (CLAS)--a 1987

CRP House of Cards

4. May 2009 William Davis (15)
Lew has coronary plaque with a heart scan score of 393. At age 53, that's in the 90th percentile (higher score than 90% of men in his age group).

On our search for causes of his coronary plaque, we identify low HDL of 41 mg/dl, high triglycerides of 202 mg/dl, small LDL (83% of total), calculated LDL of 133 mg/dl, and severe vitamin D deficiency with a starting blood level of 25-hydroxy vitamin D of 19 ng/ml.

His c-reactive protein: 4.1 mg/dl--above the cut-off of 2.0 mg/dl that the pharmaceutical industry is targeting as a mandate for statin therapy, particularly given the JUPITER data.

Lew instead eliminates wheat and other small LDL-provoking foods and, as a result, loses 28 lbs in 3 months; adds omega-3 fatty acids from fish oil; supplements vitamin D sufficient to increase his blood level to 70 ng/ml.

Along with dramatic correction of his starting abnormalities, his c-reactive protein: 0.4 mg/dl--no statin drug.

In my view, increased CRP is nothing more than a surrogate for the inflammatory phenomena that arise from high-carbohydrate diets, overweight, and small LDL. Correct those and CRP drops off a cliff. In fact, it is exceptionally rare for CRP to not drop to very low levels following this formula.

I believe that CRP is one more item on the list of reasons--the house of cards--the pharmaceutical industry is building to persuade us to take more and more statin drugs. LDL not low enough? Take more statin. Diabetic with low cholesterol? Take a statin. Inflammation? Take a statin.

Enough already.

At-home blood tests

2. May 2009 William Davis (6)
Our at-home blood tests are proving a hit.

So far, vitamin D is the number one most popular test, no surprise.

Second--to my surprise--is DHEA. I would have predicted it would have been thyroid testing.

Our male and female hormone panels are also proving popular.

I've personally been using the thyroid and vitamin D testing to monitor my levels. I increased my Armour thyroid based on a low free T3 value, while my vitamin D was perfect at 77 ng/ml on 8000 units vitamin D3 (cholecalciferol) per day.

The process of performing the blood spots is straightforward. The finger pricks are virtually painless using the automatic spring-loaded finger stick devices:





The number of blots to make depends on how many tests you'd like. Just a vitamin D test requires 2 blots. If 6 or more tests are ordered at a time, then all 12 blots should be made. (Two spring-loaded lancets are provided in each kit.)





If you are interested in any of our at-home blood tests, go here.

Our own Heart Hawk has posted an editorial on about blood spot testing on Health Central:

Simple, affordable home blood testing is a real game-changer in the arena of informed, self-directed healthcare. For the first time broad access to home blood testing, on a scale similar to that enjoyed by persons who routinely test their blood sugar, is available to virtually everyone and it removes doctors as the gatekeepers of these tests. Even private insurance companies and Medicare are beginning to understand the potential for improving healthcare and decreasing costs and are slowly beginning to expand coverage of home blood testing much as they do for diabetics or persons taking anti-coagulants.

"Help keep your family goiter free"

1. May 2009 William Davis (10)
People ask, "If I need iodine, should I go back to iodized salt?"

First of all, how did this notion of iodized salt originate?

In 1924, J. Edgar Hoover was appointed head of the FBI, Marlon Brando and Doris Day were born, and Calvin Coolidge was elected President of the United States. Half of American households had a car, while 1 in 4 Americans were illiterate.



In the 1920s, cities were a fraction of their current size and a third of the U.S. population, or 36 million people, lived in small rural communities.

Goiters were also wildly prevalent in 1924. Up to a third of the population in some areas of the country, particularly the Midwest, suffered from goiters, thyroid glands that enlarged due to lack of iodine.

Goiters were not only unsightly, but sometimes grotesque, causing a visible bulge in the front of the neck. Occasionally, they would grow so big that it compressed adjacent structures, like the trachea, and would have to be surgically removed. Goiters were commonly associated with thyroid dysfunction, especially low thyoid or hypothyroidism, that resulted in low IQ's in schoolchildren, debilitation in adults. Women of childbearing age delivered retarded children.

So iodine deficiency in early 20th century America was a big problem. How to solve this enormous public health problem in a large nation without television, few radios, no internet, with a largely rural and often illiterate population?

Thus was iodized salt born, a simple, technologically available solution that could be implemented on a large scale nationwide at low cost. The FDA chose this route in 1924, figuring that it was the best way to ensure that most Americans could obtain sufficient iodine through liberal use of iodized salt. Public health officials urged Americans to use salt. Morton's salt label proudly bore the slogan "Help keep your family goiter free!"

It worked. Goiters largely became a thing of the past.

How about today? The American Heart Association recommends limiting salt, recently announcing that they would like to limit intake to 1500 mg per day. The American Medical Association has been lobbying the FDA to set lower salt limit guidelines. The FDA has been clamping down on food manufacturers to reduce the quantity of salt in processed foods.

Why limit salt? The concern is that there are segments of the population (not all) that are salt sensitive, particularly African Americans, people with certain genetic forms of high blood pressure, conditions that cause water retention, and any degree of heart or kidney failure. Salt in these peoplem, in fact, can be disastrous.
So adding iodine to salt was the solution to epidemic goiter. And it worked.

But salt is not a perfect solution, just one that served its purpose back in 1924. What we need is a 21st century solution.
You will find that in the various iodine supplements at your health food store. My favorite is kelp--inexpensive, available, and a form that mimics the way Japanese people obtain iodine (though by eating seaweed, rather than with tablets).
