Man walks after removing wheat

9. May 2010 William Davis (27)

No, this isn't some National Enquirer headline like "Woman delivers alien baby."

Tom is a 26-year old man with a complex medical condition, a malformation he was born with and has had reconstructed. Aside from this, he leads a normal life: works, is married, and is, in fact, quite intelligent.

He came to me for an opinion regarding his overall health. Tom was worried that his congenital condition would impair his long-term health and longevity prospects, so he wanted to optimize all other aspects of his health.

But, when I examined Tom, he could barely get himself up on the exam table without wincing in pain. When I asked him to walk, he hobbled a few steps, again clearly in pain. When I asked him what hurt, he said "everything." He said that all his joints hurt just to move.

He told me that his several doctors over the years didn't know why he was in such pain: It wasn't rheumatoid arthritis, gout, pseudogout, or any of the other inflammatory joint diseases that might account for virtually incapacitating this 26-year old man. Even the rheumatologists were stumped. It was also unrelated to his repaired congenital condition. So Tom went on with his life, barely able to even go for a walk with his wife without pain, slowing him down to the pace of an 80-year old.

So I suggested that he eliminate all wheat products. "I don't know for a fact whether it will work, Tom. But the only way to find out is to give it a try. Why not try a 4-week period of meticulously avoiding wheat? Nothing bad will come of it."

He and his wife look perplexed, but were so desperate for a solution that they agreed to give it a try.

Tom returned 6 weeks later. He walked into the room briskly, then bounded up on the exam table. He told me that, within days, all his joint pains had completely disappeared. He could walk, stretch, do all the normal physical things with none of the pain he had suffered previously.

Tom told me, "I didn't think it could be true. I thought it was just a coincidence. So I had a sandwich about 2 weeks into it. In about 5 minutes, I got about half my pains back."

Tom now remains wheat-free and pain-free, thankfully with no discernible joint impairment.

So, yes, Tom walked freely and without pain simply by eliminating wheat from his life.

Is it an immune phenomenon? Does wheat gluten trigger some inflammatory reaction in some people? There is surely something like this underlying experiences like Tom.

Wheat contains far more than gluten. Modern wheat is a collection of hundreds of different proteins, though gluten is the most plentiful, the one that confers the "viscoelasticity" of dough. But there's plenty more to wheat than gluten or celiac disease.

AGEing gracefully

5. May 2010 William Davis (32)

Advanced Glycation End-products, or AGEs, have the potential to change our entire conversation about diet.

AGEs come from two principal sources:

1) Endogenous--Glucose-protein interactions that arise from high blood glucose levels

2) Exogenous--From diet

The first is sensitive to glucose levels: the higher the glucose level, the greater the AGE formation. The second depends on the quantity of AGE in the food consumed.

A compelling body of evidence points towards AGEs as an agent of aging, as well as kidney dysfunction, dementia, and atherosclerosis. Some of the observations made include:

--If AGEs are infused into an experimental animal, it develops atherosclerosis, kidney disease, and other "diseases of senescence" within weeks to months.

--In endothelial cells (cells lining arteries), AGE induces expression of adhesion molecules and inflammatory signals. In fibroblasts, AGE provokes collagen production. In smooth muscle cells, AGE triggers migration and proliferation. In monocytes and macrophages, AGEs induce chemotaxis and release of inflammation mediators. In short, AGEs have been implicated in just about every step leading to atherosclerosis.

--In humans, greater quantities of AGEs are present in diabetics, pre-diabetics and people with insulin resistance. We all know that these people develop atherosclerosis, kidney disease, cataracts, and other conditions at an accelerated rate.

--Foods containing greater quantities of AGEs cause endothelial dysfunction, i.e., artery constriction via blockade of nitric oxide and other mechanisms.

Short of taking agents that block AGE activity, how can you minimize the absorption or production of AGEs? There are two general strategies:

1) Keep blood glucose low--The Whitehall study demonstrated increased cardiovascular mortality with a postprandial (actually 2-hour post- 50-gram glucose challenge) blood sugar of 83 mg/dl. Lower blood glucose, less glycation. Less carbohydrates in the diet, the lower the blood sugar, the less the glycation. Studies like Whitehall demonstrate that glycation begins with glucose values within the normal range. Thus, aging occurs even with normal glucose levels. It occurs faster with higher glucose levels.

2) Choose and prepare foods with lower AGE content. Food content of AGEs is a major determinant of blood AGE levels. Fats and meats are the primary dietary source of AGEs, particularly if cooked at high temperature (broiling, frying). While this does not mean that meats and fats need to be avoided, it can mean that limiting serving size of meats and fats, while being selective in how they are prepared, are important. This can mean cutting your meats in thinner slices or smaller pieces to permit faster cooking, eating rare when possible (not poultry, of course), avoiding cooking with sauces that contain sugar (which enhances AGE formation). Is this an argument in favor of sashimi?

Minimizing exposure to AGEs, endogenous or exogenous, has the potential to slow the aging process, or at least to lessen the likelihood of many of the phenomena of aging.

More on this to come.

Small LDL: Simple vs. complex carbohydrates

4. May 2010 William Davis (17)

Joseph is a whip-smart corporate attorney, but one who accepts advice at his own pace. He likes to explore and consider each step of the advice I give him.

Starting (NMR) lipoprotein panel on no treatment or diet change:

LDL particle number 2620 nmol/L (which I would equate to 262 mg/dl LDL cholesterol)
Small LDL 2331 nmol/L--representing 89% of LDL particle number, a severe dominance of small LDL

I advised him to eliminate wheat, cornstarch, and sugars, while limiting other carbohydrate sources, as well. Joseph didn't like this idea very much, concerned that it would be impractical, given his busy schedule. He also did a lot of reading of the sort that suggested that replacing white flour with whole grains provided health advantages. So that's what he did: Replaced all sugar and refined flour products with whole grains, but did not restrict his intake of grains.

Next lipoprotein panel with whole grains replacing white refined flour:

LDL particle number 2451 nmol/L
Small LDL 1998 nmol/L--representing 81.5% of LDL particle number.

In other words, replacing white flour products with whole grain products reduced small LDL by 14%--a modest improvement, but hardly great.

I explained to Joseph that any grain, complex, refined, or simple--will, just like other sugars and carbohydrates, still provoke small LDL. Given the severity of his patterns, I suggested trying again, this time with full elimination of grains.

Next lipoprotein panel with elimination of whole grains:

LDL particle number 1320 nmol/L
Small LDL 646 nmol/L--48.9% of total LDL particle number, but a much lower absolute number, a reduction of 67.6%.

This is typical of the LDL responses I see with elimination of wheat products on the background of an overall carbohydrate restriction: Big drops in precisely measured LDL as LDL particle number (i.e., an actual count of LDL particles, not LDL cholesterol) and big drops in the number of small LDL particles.

You might say that wheat elimination and limitation of carbohydrate intake can yield statin-like values . . . without the statin.

Is Cocoa Puffs no longer heart healthy?

29. April 2010 William Davis (17)

Until recently, Cocoa Puffs enjoyed the endorsement of the American Heart Association (AHA) as a heart-healthy food.

For a price, the AHA will allow food manufacturers to affix a heart "check mark" signifying endorsement by the AHA as conforming to some basic "heart healthy" requirements.

Odd thing: The list of breakfast cereals on the check mark program has shrunk dramatically. When I last posted about this, there were around 50-some breakfast cereals, from Cocoa Puffs to Frosted Mini Wheats. Now, the list has been trimmed down to 17:

Berry Burst Cheerios-Triple Berry
Cheerios
Cheerios Crunch
Honey Nut Cheerios
Kashi Heart to Heart Honey Toasted Oat Cereal
Kashi Heart to Heart Oat Flakes & Wild Blueberry Clusters
Kashi Heart to Heart Warm Cinnamon Oat Cereal
Multi Grain Cheerios
Oatmeal Crisp Crunchy Almond
Oatmeal Crisp Hearty Raisin
Quaker Cinnamon Life
Quaker Heart Health
Quaker Life
Quaker Life Maple & Brown Sugar
Quaker Oat Bran
Quaker Oatmeal Squares - Brown Sugar
Quaker Oatmeal Squares - Cinnamon

According to sales material targeted to food manufacturers, the American Heart Association boasts that "The American Heart Association’s heart-check mark is the most recognized and trusted food icon today . . . Eighty-three percent of consumers are aware of the heart-check mark. Sixty-six percent of primary grocery shoppers say the heart-check mark has a strong/moderate influence on their choices when shopping."

So, is Cocoa Puffs no longer heart healthy?

I suspect that agencies like the AHA, the USDA, the American Diabetes Association as starting to understand that they have blundered big time by pushing low-fat, having contributed to the nationwide epidemic of obesity and diabetes, and that it is time to quietly start backpedaling.

While it's a step in the right direction, judging from the above list of breakfast cereal "survivors" of the check mark program, the criteria may have been tightened . . . but not that much.

Fractures and vitamin D

27. April 2010 William Davis (25)

This is a bit off topic, but it's such an interesting observation that I'd like to pass it on.

Over the past several years, there have been inevitable bone fractures: People slip on ice, for instance, and fracture a wrist or elbow. Or miss a step and fracture a foot, fall off a ladder and fracture a leg.

People will come to my office and tell me that their orthopedist commented that they healed faster than usual, often faster than anyone else they've seen before. My son was told this after he shattered his hand getting slammed against the boards in hockey; his orthopedist took the screws and cast off much sooner than usual since he judged that healing had occured early. (My son was taking 8000 units vitamin D in gelcap form; I also had him take 20,000 units for several days early after his injury to be absolutely sure he had sufficient levels.)

My suspicion is that people taking vitamin D sufficient to enjoy desirable blood levels (I aim for a 25-hydroxy vitamin D level of 60-70 ng/ml) heal fractures much faster, abbreviating healing time (crudely estimated) by at least 30%.

For any interested orthopedist, it would be an easy clinical study: Enroll people with traumatic fractures, randomize to vitamin D at, say, 10,000 units per day vs. placebo, watch who heals faster gauged by, for instance, x-ray. My prediction: Vitamin D will win hands down with faster healing and perhaps more assured fusion of the fracture site.

T3 for accelerating weight loss

25. April 2010 William Davis (57)

Supplementation of the thyroid hormone, T3, is an underappreciated means to lose weight.

Thyroid health, in general, is extremely important for weight control, since even subtle low thyroid hormone levels can result in weight gain. The first step in achieving thyroid health is to be sure you are obtaining sufficient iodine. (See Iodine deficiency is real and Healthy people are the most iodine deficient) But, after iodine replacement has been undertaken, the next step is to consider your T3 status.

I've seen T3 ignite weight loss or boost someone out of a weight loss "plateau" many times.

Endocrinologists cringe at this notion of using T3. They claim that you will develop atrial fibrillation (an abnormal heart rhythm) and osteoporosis by doing this. I have yet to see this happen.

Adding T3 revs up metabolic rate at low doses. The idea is to push free T3 hormone levels to the upper limit of normal, but not to the hyperthyroid range. While an occasional person feels a little "hyper" like they've had a pot of coffee, most people just feel energized, clear-headed, and happier. And weight trends down much more readily.

Taking T3 by itself with no effort at weight loss generally yields only a modest weight reduction. However, T3 added to other weight reducing efforts, such as wheat elimination and exercise, accelerates the weight loss effect considerably. 5 lbs lost will likely be more like 8 to 10 lbs lost; 10 lbs lost will likely be more like 15 to 20 lbs, etc.

It's also my suspicion that more and more people are developing a selective impairment of T3, making it all the more important. I believe that you and I are being exposed to something (perchlorates, bisphenol A, perflurooctanoic acid, and others?) that may be impairing the 5'-deiodinase enzyme that converts the T4 thyroid hormone to the active T3. Relative lack of T3 leads to slowed metabolism, weight gain, and depressed mood. While avoiding or removing the toxin impairing 5'-deiodinase would be ideal, until we find out how to do this, taking T3 is a second best.

The tough part: Finding a prescriber for your T3.

The world according to the Wheat Foods Council and the Whole Grains Council

23. April 2010 William Davis (26)

You might get a kick out of what the Wheat Foods Council and the Whole Grains Council recommend for a sample meal plan:

Breakfast: Whole grain raisin toast

Lunch: Sandwich on whole grain
Snack: Rye bread crackers
Dinner: Whole grain pasta with your favorite sauce

Breakfast: Whole grain waffles

Lunch: Hamburger on whole grain bun

Snack: Graham crackers

Dinner: Whole grain homemade pizza on whole grain pita crust

Remember Morgon Spurlock's documentary movie, Super Size Me? (If you haven't already seen it, Super Size Me is viewable for free on Hulu.) Spurlock conducts a self-inflicted 30-day experiment of eating at McDonald's fast food restaurants every day. In short, the results on Spurlock's weight and health are disastrous.

How about Wheat Belly: The Movie? We would chronicle our star through a 30-day course of meals served up by the Wheat Foods and Whole Grains Councils, all featuring wonderful wheat products in every meal. We could measure blood sugar, triglycerides, LDL, small LDL, weight, etc.

Any predictions?

Why bananas increase cholesterol

21. April 2010 William Davis (0)

Anything that increases postprandial (after-eating) blood sugar will increase the number of LDL particles in the blood.

An increase in LDL particles is an important factor in causing heart disease: The greater the number of LDL particles, the more opportunity they have to interact with the walls of arteries, contributing to atherosclerosis.

Carbohydrates increase small LDL, especially if postprandial sugar is increased. Here's another way carbohydrates increase LDL particles: The duration of time LDL particles hang around in the blood stream is doubled.

When blood sugar increases, such as after the 30 grams carbohydrates in a medium-sized banana, glycation of LDL particles occurs. This means that a gglucose (sugar) molecule reacts with a lysine residue in the apoprotein B of the LDL particle. This induces a change in conformation that makes it less readily recognized by the LDL receptor. Thus, the glycated LDL particle persists for a longer period of time in the blood stream.

LDL particles are therefore cleared less efficiently, numbers of LDL particles increase.

Plant-based or animal-based?

19. April 2010 William Davis (78)

The ideal diet for heart and overall health restricts carbohydrate intake. I say this because carbohydrates:

Make you fat--Carbohydrates increase visceral fat, in particular.
Increase triglycerides
Reduce HDL
Increase small LDL particles
Increase glycation of LDL
Increase blood pressure
Increase c-reactive protein

Reducing carbohydrates reverses all the above.

But here's a common mistake many people make when following a low-carbohydrate diet: Converting to a low-carb, high-animal product diet.

It accounts for a breakfast of a 3-egg omelette with cheese and butter, 4 strips of bacon, 2 sausages, cream in coffee. Low-carb? It certainly is. But it is a purely high-animal product, no-plant-based meal.

I believe a strong argument can be made that a low-carbohydrate but plant-based diet with animal products as the side dish is a better way to go.

Consider that:

1) Animal products have little to no fiber, while plant-based products like spinach, avocado, and walnuts and other raw nuts have substantial quantities.

2) Plant products are a source of polyphenols and flavonoids--This encompasses a large universe of nutrients, from epigallocatechins in tea, polymeric procyanidins from cocoa, to hydroxytyrosol from olives, and anthocyanins from red wine and eggplant. The inflow of these beneficial compounds needs to be frequent and generous, not piddly amounts taken infrequently.

3) Vitamin C--While it's easy to obtain, the fact that you and I need to obtain vitamin C from frequent ingestion of plant sources suggests that humans were meant to eat lots of plants. While it may require a few months of deficiency before your teeth fall out, imagine what low-grade deficiency can do over a long period.

4) Vitamin K1--Rich in green vegetables, vitamin K1 is virtually absent in animal products.

5) Tocotrienols--I've been watching the data on this fascinating family of powerful oil-soluble antioxidants unfold for 20 years. Tocotrienols come only from plants. (I recently had an extended conversation with the brilliant biochemist, Dr. Barrie Tan, who is incredibly knowledgeable about tocotrienols, having developed several methods of extraction from plants, including his discovery of the highly concentrated source, annatto. Be sure to watch for future conversations about tocotrienols.)

6) Meats and dairy yield a net acid load--While plant foods are net basic. At the very least, this yields risk for osteoporosis, since acids are ultimately buffered by basic calcium salts from the bones. Tissue and blood pH is a tightly regulated system; veering off just a teensy-weensy bit from the normal pH of 7.4 to an acidic pH of, say, 7.2, leads to . . . death. In short, pH control is very important. A net acid challenge from animal products is a lot like drinking carbonated soda, a huge acid challenge that leads to osteoporosis and other health issues.

Conversely, a pure plant-based diet has its own set of problems. Eating a pure plant-based diet can lead to deficiencies of vitamin B12, omega-3 fatty acids (no, linolenic acid from flaxseed will NOT cut it), vitamin K2, carnitine, and coenzyme Q10.

So, rather than a breakfast of 3-egg omelet with bacon, sausage, cream, and cheese, how about a handful of pecans, some blueberries, and a 2-egg omelet made with basil-olive oil pesto? Or a spinach salad with walnuts, feta cheese, and lots of olive oil?

Fat is not the demon

16. April 2010 William Davis (36)

So my patient, Dane, generously volunteered to be on the Dr. Oz show, as I discussed previously.

What we didn't know, nor did the producer who contacted us mention, that Dane would be counseled by low-fat guru Dr. Dean Ornish on a strict low-fat diet. The teaser introduction essentially tells the entire story.

Ironically, that is the exact opposite of the dietary program that I advocate. I rejected the 10% fat diet long ago after I became a type II diabetic, gained 30 lbs, and suffered miserable deterioration of my cholesterol values on this diet. I also witnessed similar results in many hundreds of people, all following a strict low-fat diet. In fact, elimination of wheat--whole, white, or otherwise--along with limitation or elimination of all other grains has been among the most powerful health strategies I have ever witnessed.

I now regret having subjected my patient to this theatrical misinformation. Dane is a smart cookie--That's probably why he was not allowed more than a "yes" or "no" during Dr. Oz's monologue, else Dane might have pitched in about some ideas that would have tripped Oz and Ornish up.

In their defense, if we took 100 Americans all following a typical 21st century diet of fast food, white bread buns, Coca Cola and other soft drinks, chips, barbecue sauce, and French fries, converting to a plant-based, high-carbohydrate, grain-rich diet is indeed an improvement. People will, at first, lose weight and enjoy an initial response. (The occasional person with the Apo E4 genetic pattern, heterozygote or homozygote, may even enjoy long-term benefits, a topic for another day.)

But the majority of people, in my experience, after an initial positive response to an Ornish-like low-fat, high-carbohydrate diet will either plateau (stay overweight, have low HDL, high triglycerides, plenty of small LDL, and high blood sugars) or deteriorate, much as I did.

Thankfully, Dane has been a good sport about this, understanding that this is essentially show business. I believe he understands that the information was all well-intended and, after all, we are all working towards the same goal: reduction of heart disease risk.

By the way, regardless of which diet you follow, it is, in my view, absurd to believe that diet alone will do it. What about vitamin D normalization, thyroid normalization (thyroid disease is incredibly common), omega-3 fatty acids from fish oil, identification of hidden sources of risk (something that is unlikely in Ornish, since small LDL particles skyrocket on a low-fat diet), postprandial glucoses, etc., all the pieces we focus on to gain control over coronary plaque? Eating green peppers and barley soup alone is not going to do it.

Brainwashed!

9. August 2006 William Davis (0)

At a social gathering this weekend, as we humans like to do, someone asked me what I did for a living. I told him I was a cardiologist.

"What hospital do you work at?" he asked.

This is invariably the response I get whenever I tell people what I do. I wouldn't make much of it except that it happens just about every time.

This indicates to me just how successful hospitals, my colleagues, cardiac device manufacturers, and others supporting the status quo in heart care, have been in persuading us that the place for heart disease is the hospital--period.

Tense families, drama, high-tech...It all takes place in the hospital.

Yet the people destined to be the fodder for hospital heart care are presently well, mostly unaware of what the future holds. Also unaware that heart disease is readily, easily, inexpensively, and accurately identifiable. Ask anyone in the Track Your Plaque program who's had a CT heart scan.

We all need to rid ourselves of the idea that the hospital is the place for heart disease. If the coronary plaque behind heart attack is easy to detect and controllable, there's little or no need for the hospital for the vast majority of us.

In the majority of instances of coronary disease, the hospital should be the place for the non-compliant and the ill-informed, and not for those of us sufficiently motivated to know and do better. The formula is simple: 1) Quantify plaque with a CT heart scan, 2) Identify the causes, then 3) Correct the causes.

The Fanatic Cook: A fabulous Blog about food and nutrition

7. August 2006 William Davis (0)

I came across this Blog authored by a nutritionist when it was highlighted on Blogger as an interesting site:

The Fanatic Cook at http://fanaticcook.blogspot.com/

I was thoroughly impressed with the insightful and entertaining commentary. I'd highly recommend this site to you for reading on nutrition. In particular, her coenzyme Q10 column was exceptionally well written and clear.(http://fanaticcook.blogspot.com/2005/02/statins-and-not-well-publicized-side.html)

Also read her column, Super NonFoods at http://fanaticcook.blogspot.com/2005/07/super-nonfoods.html.

There's also oodles of recipes, all for the taking.

Eggs: Good, bad, or indifferent?

5. August 2006 William Davis (3)

Eggs have been in the center of the cholesterol controversy almost from the very start.

The traditional argument against eggs went that eggs, high in cholesterol (210-275 mg per egg)and with some saturated fat (1.5-2.5 grams per egg), raised blood cholesterol (and LDL). Out went the daily fried, scrambled, poached eggs that many Americans indulged in most mornings. (We replaced it with more breakfast cereals and other carbohydrate conveniences, then got enormously overweight.)

A large Harvard epidemiologic study in 1999 called this observation into question. They tracked the fate of 117,000 thousand people and then compared the rate of heart attack, death, and other cardiovascular events among various people correlated to the "dose" of eggs they ate. Egg intake varied from none to 7 or more per week. Lo and behold, people who ate more eggs appeared to not suffer more events.

This study, large and well-conducted by an internationally respected group of investigators, seem to reopen the gates for more egg consumption, though most Americans still consume eggs cautiously.

Deeper down in this study, however, was another observation: People with diabetes who ate 1 egg per day had double the risk of heart attack. Because this study was observational, no specific conclusion as to why could be drawn.

A new study conducted by a Brazilian group may shed some light. Healthy (non-diabetic) men were fed an emulsion of several eggs. Inclusion of plentiful yolks caused a dramatic slowing of fat clearance from the blood. Specifically, "chylomicron remnants" were abnormally persistent in the blood. Chylomicron remnants are potent causes of coronary plaque. (Chylomicron remnants can be measured fairly well by intermediate-density lipoprotein and VLDL by NMR, or IDL by VAP.)

Diabetics are know to have substantial disorders of after-meal fat clearance, including an excess of chylomicron remnants. Could the Brazilian observation be the explanation for the increased event rate in diabetics in the Harvard study? Interesting to speculate.

We continue to tell our patients that eating eggs in moderation is probably safe. After all, there are good things in eggs: the high protein in the egg white, lecithin in the yolk. It is the yolk's contents that are in question, not the white. Thus, you and I can eat all the egg whites (e.g., Egg Beaters) we want. It's the safety of yolks that are uncertain.

The abnormal after-eating effect suggested by the Brazilians opens up some very interesting questions and confirms that we should still be cautious in our intake of egg yolks. One yolk per day is clearly too much. What is safe? The exisitng information would suggest that, if you have diabetes, pre-diabetes, or a postprandial disorder (IDL, VLDL), you should minimize your egg yolk use, perhaps no more than 3 or so per week, preferably not all at one but spaced out to avoid the after-eating effect.

Others without postprandial disorders may safely eat more, perhaps 5 per week, but also not all at one but spaced out.

Track Your Plaque Members: Be sure to read our upcoming Special Report on Postprandial Disorders. It contains lots of info on what this important pattern is all about. Postprandial disorders are largely unexplored territory that hold great promise for tools to inhibit coronary plaque growth and drop your heart scan score. The Brazilian study is just one of many future studies that are likely to be released in future about this very fascinating area.

Diabetes is Track Your Plaque's Kryptonite!

3. August 2006 William Davis (0)

If there's one thing I truly fear from a heart scan score reduction/coronary plaque regression standpoint, it's diabetes.

I saw a graphic illustration of this today. Roy came into the office after his 2nd heart scan. His first scan 14 months ago showed a score of 162. Roy started out weighing well over 300 lbs and with newly-diagnosed adult diabetes.

Roy put extraordinary effort into his program. He lost nearly 70 lbs by walking; cutting processed carbohydrates, greasy foods, and slashing overall calories. His lipoproteins, disastrous in the beginning, were falling into line, though HDL was still lagging in the low 40s, as Roy remains around 60 lbs overweight, even after the initial 70 lb loss.

Unfortunately, despite the huge loss in weight, Roy remains diabetic. On a drug called Actos, which enhances sensitivity to insulin, along with vitamin D to also enhance insulin response, his blood sugars remained in the overtly diabetic range.

Roy's repeat heart scan showed a score of 482--a tripling of his original score.

Obviously, major changes in Roy's program are going to be required to keep this rate of growth from continuing. But I tell Roy's story to illustrate the frightening power of diabetes to trigger coronary plaque growth.

Like Kryptonite to Superman (remember George Reeves crumbling and falling to his knees when the bad guys got a hold of some?), diabetes is the one thing I fear greatly when it comes to reducing your heart scan score. As you see with Roy's case, diabetes can be responsible for explosive plaque growth, more than anything else I know.

The best protection from diabetes is to never get it in the first place. (See my earlier Blog, "Diabetes is a choice you make".)

Boy, was I wrong!

1. August 2006 William Davis (0)

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

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

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

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

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

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

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

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

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

Don't forget how dangerous heart disease can be

29. July 2006 William Davis (0)

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

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

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

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

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

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

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

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

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

How many ways can you disguise sugar?

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

The Best New Healthy Foods for Busy People
from Health

The foods on their list:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Diabetes is a choice you make

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

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

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

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

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

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

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

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

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

I'll call the doctor when I feel bad!

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

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

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

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

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

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

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

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

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