. . . or beans, or brown rice, or sweet potatoes? Or how about amaranth, sorghum, oats, and buckwheat? Surely corn on the cob is okay!

These are, of course, non-wheat carbohydrates. They lack several crucial undesirable ingredients found in our old friend, wheat, including no:

Gliadin--The protein that degrades to exorphins, the compound from wheat digestion that exerts mind effects and stimulates appetite to the tune of 400 additional calories (on average) per day.
Gluten--The family of proteins that trigger immune diseases and neurologic impairment.
Amylopectin A--The highly-digestible "complex" carbohydrate that is no better--worse, in fact--than table sugar.

So why not eat these non-wheat grains all you want? If they don't cause appetite stimulation, behavioral outbursts in children with ADHD, addictive consumption of foods, dementia (i.e., gluten encephalopathy), etc., why not just eat them willy nilly?

Because they still increase blood sugar. Conventional wisdom is that these foods trend towards having a lower glycemic index than, say, table sugar, meaning it raises blood glucose less.

That's true . . . but very misleading. Oats, for instance, with a glycemic index of 55 compared to table sugar's 59, still sends blood sugar through the roof. Likewise, quinoa with a glycemic index of 53, will send blood sugar to, say, 150 mg/dl compared to 158 mg/dl for table sugar--yeah, sure, it's better, but it still stinks. And that's in non-diabetics. It's worse in diabetics.

Of course, John Q. Internist will tell you that, provided your blood sugars after eating don't exceed 200 mg/dl, you'll be okay. What he's really saying is "There's no need for diabetes medication, so you're okay. You will still be exposed to the many adverse health consequences of high blood sugar similar to, though less quickly than, a full diabetic, but that's not my problem."

In reality, most people can get away with consuming some of these non-wheat grains . . . provided portion size is limited. Beyond limiting portion size, there are two ways to better manage your carbohydrate sensitivity to ensure that metabolic distortions, such as high blood sugar, glycation, and small LDL particles, are not triggered.

More on that in the future.

With the recent refinements in our approach to correction of the lipoprotein abnormalities that lead to coronary plaque and heart disease risk, I have been witnessing more and more people achieve:

Small LDL particles 0 nmol/L
Lipoprotein(a) 0 nmol/L

For instance, Ted, a 58-year old man I saw in the office today started with:

Small LDL 1673 nmol/L
Lipoprotein(a) 219 nmol/L

In other words, both small LDL particles and lipoprotein(a) are being knocked down to zero values.

Incidentally, the combination of lipoprotein(a) with small LDL is among the most atherogenic (atherosclerotic plaque-causing) patterns known. Despite his athletic, slender build and avoidance of unhealthy habits, Ted's heart scan score was 922--very high.

So Ted followed the diet I advocate, i.e., wheat elimination followed by elimination of cornstarch, oats, and sugars; high-dose fish oil (total daily EPA + DHA of 6000 mg/day); vitamin D supplementation sufficient to achieve a 25-hydroxy vitamin D level of 60-70 ng/ml; iodine supplementation; and thyroid normalization which, in Ted's case, required supplementation with the T3 thyroid hormone, liothyronine, at a small dose.

The result:

Small LDL particles 0 nmol/L
Lipoprotein(a) 0 nmol/L

Not everybody, of course, is achieving these incredible--and previously impossible--results. But the numbers are growing. Ted is the third person to achieve zeroes all around, in fact, over the past 10 days.

Heart disease prevention is getting better and more powerful every day. And it ain't all about Lipitor and low-fat.

Biscotti are twice-baked biscuits or cookies that are perfect for dipping into coffee, latté, or espresso. These wheat-free, low-carb biscotti are rich with the taste of chocolate and almonds.

Yield: approximately 15 biscotti

Ingredients:

2 cups almond meal
½ cup chopped walnuts
1/4 cup cocoa powder (undutched)
½ cup dark chocolate chips
Sweetener equivalent to ½ cup sugar (e.g., liquid stevia, Truvia)
½ cup ricotta cheese, room temperature (replace with coconut milk if lactose intolerant)
4 tablespoons butter, melted (replace with coconut oil if lactose intolerant)
2 large eggs
¼ cup milk, unsweetened almond milk, or soy milk
¼ cup almond, peanut, or sunflower seed butter, room temperature

Preheat oven to 350º F.

Mix almond meal, walnuts, sweetener, cocoa powder, and chocolate chips in bowl. Mix in ricotta, butter, eggs, milk, and nut butter and blend by hand thoroughly.

Pour mix onto baking pan lined with parchment paper or greased with coconut oil or other oil. Shape into loaf approximately 1 inch deep and 3½ to 4 inches in width. Place in oven and bake for 40 minutes.

Remove loaf and allow to cool 15 minutes. Slice into approximately ¾-inch widths and lay each biscotto on its side on baking pan. Put back in oven for 10 minutes.

Remove pan and flip biscotti over. Place back in oven and bake an additional 5 minutes. Remove and cool.

Optional: For a little dark chocolate "icing":
Melt 3-4 oz semisweet or dark chocolate in microwave (in 15 second increments until melted) or in metal bowl placed in heated water. Stir in 1-2 teaspoons butter.
Dip each biscotti into melted chocolate mix or drizzle chocolate mixture over top of each biscotto.

Here's a great way to enjoy the health benefits of green tea during the summer: sun green tea.

I dropped two green tea bags into approximately one-half gallon of cold water in a clear glass jar. I placed the jar in the sun (with top on) for four hours, then brought it into the kitchen. I served it as iced tea with a slice of lemon and mint leaf.

The sun green tea was a smoother than standard green tea brewed with hot water. Ordinarily, if you brew hot green tea for more than 3-5 minutes, it becomes more bitter or tannic. This sun green tea, despite steeping for four hours, was not the least bit bitter or tannic.

The green tea lasted well for about 48 hours, more than enough to enjoy several glasses per day.

Have you lost at least 1/2 your weight, e.g., 300 lbs down to 150 lbs? If you have, I have a major national magazine editor looking to talk to you.

If you have gone wheat-free and/or followed the dietary advice offered here in The Heart Scan Blog or through the Track Your Plaque program and would be willing to share your story, please let me know by commenting below. While losing half your body weight is not necessarily a requirement for health, it makes an incredibly inspiring story for others.

If we use your story, I will set aside a copy of my soon-to-be-released book, Wheat Belly.

High-dose omega-3 fatty acids from fish oil has become the number one strategy for reduction of lipoprotein(a), Lp(a), in the Track Your Plaque program for gaining control over coronary plaque and heart disease risk.

The original observations made in Tanzanian Bantus in the Lugalawa Study by Marcovina et al first suggested that higher dietary exposure to fish and perhaps omega-3 fatty acids from fish were associated with 40% lower levels of Lp(a). Interestingly, higher omega-3 exposure was also associated with having the longer apo(a) "tails" on Lp(a) molecules, a characteristic associated with more benign, less aggressive plaque-causing behavior.

Of course, the 600+ fish- consuming Bantus in the study consumed fish over a lifetime, from infancy on up through adulthood. So what is the time course of response if us non-Bantus take higher doses of fish oil to reduce Lp(a)?

We have been applying this approach in the Track Your Plaque program and in my office practice for the past few years. To my surprise, the majority of people taking 6000 mg per day of omega-3 fatty acids, EPA and DHA, will drop Lp(a) after one year. Some have required two years. Therefore checking Lp(a) after, say, 3 or 6 months, is nearly useless. (An early response does, however, appear to predict a very vigorous 1-2 year response.)

I'm sure that there is an insightful lesson to be learned from the incredibly slow response, but I don't currently know what it is. But this strategy has become so powerful, despite its slow nature, that it has allowed many people to back down on niacin.

There it is, sitting quietly tucked under your diaphragm, nestled beneath layers of stomach and intestines, doing its job of monitoring blood sugar, producing insulin, and secreting the digestive enzymes that allow you to convert a fried egg, tomato, or dill pickle into the components that compose you.

But, if you've lived the life of most Americans, your pancreas has had a hard life. Starting as a child, it was forced into the equivalent of hard labor by your eating carbohydrate-rich foods like Lucky Charms, Cocoa Puffs, Hoho's, Ding Dongs, Scooter Pies, and macaroni and cheese. Into adolescent years and college, it was whipped into subservient labor with pizza, beer, pretzels, and ramen noodles. As an adult, the USDA, Surgeon General's office and other assorted purveyors of nutritional advice urged us to cut our fat, cholesterol, and eat more "healthy whole grains"; you complied, exposing your overworked pancreas to keep up its relentless work pace, spewing out insulin to accommodate the endless flow of carbohydrate-rich foods.

So here we are, middle aged or so, with pancreases that are beaten, worn, hobbling around with a walker, heaving and gasping due to having lost 50% or more of its insulin-producing beta cells. If continued to be forced to work overtime, it will fail, breathing its last breath as you and your doctor come to its rescue with metformin, Actos, Januvia, shots of Byetta, and eventually insulin, all aimed at corralling the blood sugar that your failed pancreas was meant to contain.

What if you don't want to rescue your flagging pancreas with drugs? What if you want to salvage your poor, wrinkled, exhausted pancreas, eaking out whatever is left out of the few beta cells you have left?

Well, then, baby your pancreas. If this were a car with 90,000 miles on it, but you want it to last 100,000, then change the oil frequently, keep it tuned, and otherwise baby your car, not subjecting it to extremes and neglect to accelerate its demise. Same with your pancreas: Allow it to rest, not subjecting it to the extremes of insulin production required by carbohydrate consumption. Don't expose it to foods like wheat flour, cornstarch, oats, rice starch, potatoes, and sucrose that demand overtime and hard labor out of your poor pancreas. Go after the foods that allow your pancreas to sleep through a meal like eggs, spinach, cucumbers, olive oil, and walnuts. Give your pancreas a nice back massage and steer clear of "healthy whole grains," the nutritional equivalent of a 26-mile marathon. Pay your pancreas a compliment or two and allow it to have occasional vacations with a brief fast.

Bread, gluten-free or gluten-containing, in terms of carbohydrate content, is equivalent to sugar.

Two slices of store-bought whole grain bread, such as the gluten-free bread I discussed in my last post, equals 5- 6 teaspoons of table sugar:

Some breads can contain up to twice this quantity, i.e., 10-12 teaspoons equivalent readily-digestible carbohydrate.

Here's a typical gluten-free product, a whole grain bread mix. "Whole grain," of course, suggests high-fiber, high nutrient composition, and health.

What's it made of? Here's the ingredient list:
Cornstarch, Tapioca Starch, Whole Grain Sorghum Flour, Whole Grain Teff Flour, Whole Grain Amaranth Flour, Soy Fiber, Xanthan Gum, Soy Protein, Natural Cocoa and Ascorbic Acid

In other words, carbohydrate, carbohydrate, carbohydrate, carbohydrate and some other stuff. It means that a sandwich with two slices of bread provides around 42 grams net carbohydrates, enough to send your blood sugar skyward, not to mention trigger visceral fat formation, glycation, small LDL particles and triglycerides.

Take a look at the ingredients and nutrition facts on the label of any number of gluten-free products and you will see the same thing. Many also have proud low-fat claims.

This is how far wrong the gluten-free world has drifted: Trade the lack of gluten for a host of unhealthy effects.

The majority of gluten-free foods are junk foods.

People with celiac disease experience intestinal destruction and a multitude of other inflammatory conditions due to an immune response gone haywire. The disease is debilitating and can be fatal unless all gliadin/gluten sources are eliminated, such as wheat, barley, and rye.

A gluten-free food industry to provide foods minus gliadin/gluten has emerged, now large enough to become an important economic force. Even some Big Food companies are getting into the act, like Kraft, that now lists foods they consider gluten-free.

So we have gluten-free breads, cupcakes, scones, pretzels, breakfast cereals, crackers, bagels, muffins, pancake mixes and on and on. All are made with ingredients like brown rice flour, cornstarch, tapioca starch, and potato starch. Occasionally, they are made with amaranth, teff, or quinoa, other less popular, but gluten-free, grains.

Problem: These gluten-free ingredients, while lacking gliadin and gluten, make you fat and diabetic. They increase visceral fat, cause blood sugar to skyrocket higher than nearly all other foods (even higher than wheat, which is already pretty bad), trigger formation of small LDL and triglycerides, and are responsible for exaggerated postprandial (after-eating) lipoprotein distortions. They cause heart disease, cataracts, arthritis, and a wide range of other conditions, all driven by the extreme levels of glycation they generate.

Eliminating all things wheat from the diet is one of the most powerful health strategies I have ever witnessed. But replacing lost wheat with manufactured gluten-free foods is little better than replacing your poppyseed muffin with a bowl of jelly beans.

Whenever we've relied on the food industry to supply a solution, they've managed to bungle it. Saturated fat was replaced with hydrogenated fat and polyunsaturates; sucrose replaced with high-fructose corn syrup. Now, they are replacing wheat gluten-containing foods with junk carbohydrates.

For this reason, I am bringing out a line of recipes and foods that will be wheat gliadin/gluten-free, do NOT contain the junk carbohydrates that gluten-free foods are made of, and are genuinely healthy. They are tasty, to boot.

The gluten-free industry needs to smarten up. Having a following that is free of cramps and diarrhea but are obese, diabetic, and hobbling on arthritic knees and hips is good for nobody.

Judging from what we know about vitamin D, it is highly probable that it confers substantial protection from viral infections, including swine flu.

Dr. John Cannell of the Vitamin D Council (www.vitamindcouncil.com) first connected the dots, identifying the possibility of an influence of vitamin D on incidence of flu.

In 2006, Dr. Cannell reports noticing that the patients in his psychiatric ward in northern California were completely spared from the influenza epidemic of that year, while plenty of patients in adjacent wards were coming down with flu. Dr. Cannell proposed that the apparent immunity to flu in his patients may have been due to the modest dose of 2000 units vitamin D per day he had prescribed that the patients in other wards had not been given. (Since the hospital was run by the state of California, Dr. Cannell apparently had only so much leeway with vitamin D dosing.) While it’s not proof, it’s nonetheless a fascinating and compelling observation.

A similar conclusion was reached in a recent analysis of the National Health and Nutrition Examination Survey demonstrating that the higher the vitamin D blood level, the less likely respiratory infections were.

Personally, I used to suffer through 2 or 3 episodes of a runny nose, sore throat, hacking cough, fevers and feeling crumby every winter. Over the last 3 years since I’ve supplemented vitamin D, I haven’t been sick even once. The past two years I didn’t bother with the flu vaccine, since I suspected that my immunity had been heightened: no flu either winter.

And so it has been with the majority of my patients. Since I began having patients supplement vitamin D to achieve normal blood levels (we aim for 60-70 ng/ml), viral and bacterial infections have become rare.

New research is uncovering myriad new ways that vitamin D enhances natural immune responses to numerous infections, including tuberculosis, bacteria such as those causing periodontal disease and lung infections, and viruses like the influenza virus. Enhanced immunity against cancer is also an intensive area of research on vitamin D.

Will vitamin D supplementation sufficient to achieve desirable blood levels confer sufficient immunity to swine flu should it come to your door? From what we know and what we’ve seen in the few years of vitamin D experience, I think it will in the majority. But I do believe that we should still heed public health warnings to avoid contact with others, minimize exposure to crowds, avoid travel to affected areas, etc.

The results of the latest Heart Scan Blog poll are in.

The question: How has your LDL been measured? The 187 responses broke down as:

I have only had a conventional calculated value
108 (57%)

NMR LDL particle number
35 (18%)

Apoprotein B
21 (11%)

Direct LDL cholesterol
21 (11%)

Non-HDL cholesterol
8 (4%)

I don't know what you're talking about
23 (12%)

Remember the TV game show, To Tell the Truth? Celebrities would have to guess which of three guests represented the real person, such as the notorious con man, Frank Abagnale, Jr., or Mad Magazine publisher, William M. Gaines (who stumped celebrity Kitty Carlisle, heard to exclaim, "I never figured it was him. I mean look at the way he's dressed. I was looking for someone who ran a very successful magazine, so I thought it couldn't be him!")

The celebrities playing the game were permitted to ask the three guests a series of questions, hoping to discern who was the real person vs. the two impostors. At the end, each celebrity had to guess who was truly the person of interest. "Will the real Frank Abagnale, Jr. please stand up!"

If we were to act as the celebrities in our LDL game, we quickly discover some telling facts:

--Conventional LDL cholesterol (the only value 57% of our poll respondents have had) is calculated, not measured. LDL is calculated using the 40-year old Friedewald calculation.

--Directly measured LDL cholesterol (the value 11% of respondents had) is just that: directly measured. It eliminates some of the uncertainties of calculated LDL.

--Apoprotein B-Every LDL and VLDL particle produced by the liver contains one apoprotein B molecule. ApoB therefore provides a crude particle count measure of LDL and VLDL particles. Of course, it includes VLDL and is not completely the same as just an LDL measure. Some lipid authorities Like Dr. Peter Kwiterovich have advocated that apoB replace calculated LDL, and that calculated LDL essentially be discarded.

--Non-HDL cholesterol--I mention this more for completeness. Hardly anybody uses this crude value in practice--Indeed, only 4% of our poll respondents had this measure/calculation. Non-HDL is simply total cholesterol minus HDL cholesterol = Non-HDL cholesterol. It is thus a combination of cholesterol in LDL and VLDL (triglycerides), similar to apoprotein B. While, like apoB, it is a bit different in that it includes VLDL, it has proven a superior measure of risk.

--LDL particle number--In my view, this is the gold standard for LDL and risk measurement, obtained by only 18% of our poll respondents. LDL particle number is proving superior for discriminating who is truly at risk for a cardiovascular event, particularly when metabolic syndrome or diabetes is part of the picture, i.e., when HDL and triglycerides are considerably distorted, leading to substantial corruption of calculated LDL.

While 18% is a minority, it still represents growth in recognition that conventional calculated LDL cholesterol is an unreliable, inaccurate, and outdated value. If the real LDL were to stand up, I believe that it is LDL particle number that would spring to its feet.

We already know that vitamin D reduces inflammatory processes, since several markers, including c-reactive protein and IL-6 have previously been shown to drop substantially with vitamin D. Inflammation underlies coronary atherosclerotic plaque growth, as well as plaque rupture that triggers heart attack.

A German group has now shown that the important inflammatory marker, tumor necrosis factor (TNF), is also reduced by vitamin D supplementation. Many studies have implicated increased TNF levels in promoting cancer.

In this study, a modest vitamin D dose of 3320 units (83 micrograms) was given vs. placebo. The 25-hydroxy D level reached in the treated group was 34.2 ng/ml (85.5 nmol/L), which resulted in a 26.5% reduction in TNF compared with 18.7% reduction (?) in the placebo group.

Vitamin D supplementation enhances the beneficial effects of weight loss on cardiovascular disease risk markers.

Zitterman A, Frisch S et al.

BACKGROUND: High blood concentrations of parathyroid hormone and low concentrations of the vitamin D metabolites 25-hydroxyvitamin D [25(OH)D] and calcitriol are considered new cardiovascular disease risk markers. However, there is also evidence that calcitriol increases lipogenesis and decreases lipolysis.
OBJECTIVE: We investigated the effect of vitamin D on weight loss and traditional and nontraditional cardiovascular disease risk markers in overweight subjects.
DESIGN: Healthy overweight subjects (n = 200) with mean 25(OH)D concentrations of 30 nmol/L (12 ng/mL) received vitamin D (83 microg/d) or placebo in a double-blind manner for 12 mo while participating in a weight-reduction program.
RESULTS: Weight loss was not affected significantly by vitamin D supplementation (-5.7 +/- 5.8 kg) or placebo (-6.4 +/- 5.6 kg). However, mean 25(OH)D and calcitriol concentrations increased by 55.5 nmol/L and 40.0 pmol/L, respectively, in the vitamin D group but by only 11.8 nmol/L and 9.3 pmol/L, respectively, in the placebo group.

(Calcitriol = 1,25-dihydroxy vitamin D.)

Knowing your vitamin D blood level is crucial, as individual need for vitamin D varies widely from one person to the next. You can get your vitamin D tested at home by going to Grassroots Health or the Track Your Plaque Marketplace.

It all started back in the 1960s, when ape-watching anthropologists, Drs. Jane Goodall and Richard Wrangham, observed chimps foraging for a specific variety of leaf, which they consumed whole while wrinkling their noses in presumed disgust. Subsequent study showed that the leaves contained a powerful anti-parasitic compound.

A similar observation followed in 1987 by Dr. Michael Huffman from the University of Kyoto. During his year of living in the jungles of Tanzania, he observed chimpanzees in their native habitat. On one unexpected morning, he observed a female chimp, Chausiku:

“Chausiku goes directly to and sits down in front of a shrub and pulls down several new growth branches about the diameter of my little finger. She places them all on her lap and removes the bark and leaves of the first branch to expose the succulent inner pith. She then bites off small portions and chews on each for several seconds at a time. By doing this, she makes a conspicuous sucking sound as she extracts and swallows the juice, spitting out most of the remaining fiber. This continues for 17 minutes, with short breaks as she consumes the pith of each branch in the same manner.”

Dr. Michael Huffman’s description of Chausiku documents a fascinating example of animal self-medication what some call "zoopharmacognosy."
In this instance, the chimpanzee, weak, clutching her back in pain, and listless, was ingesting the leaves of the plant, Vernonia amygdalina, to purge an intestinal parasite. She recovered by the next morning.

Vernonia leaves have since been found to contain over a dozen potential anti-parasitic compounds. Chimps in this region commonly suffer infestations of parasites like Strongyloides fuelleborni (thread worm), Trichuris trichiura (whip worm), and Oesophagostomum stephanostomum (nodular worm). They have somehow stumbled onto a treatment that they administer themselves.

Chimpanzees have inhabited earth for over 6 million years. Who knows how long they and other primates have practiced some form of self-medication.

If chimpanzees can do it, I believe that we, as human primates, can also practice a similar form of self-directed health--homopharmacognosy?

In honor of Earth Day, I thought I'd highlight the unexpectedly high carbon costs of activities in hospitals, specifically the cardiac catheterization laboratory.

A patient enters the cath lab. The groin is shaved using a plastic disposable razor, the site cleaned with a plastic sponge, then the site draped with an 8 ft by 5 ft composite paper and plastic material (to replace the old-fashioned, reusable cloth drapes). A multitude of plastic supplies are loaded onto the utility table, including plastic sheaths to insert into the femoral artery (which comes equipped with a plastic inner cannula and plastic stopcock), a multi-stopcock manifold that allows selective entry or removal of fluids through the sheath, a plastic syringe to inject x-ray dye, plastic tubing to connect all the devices (total of about 5 feet), and multiple plastic catheters (3 for a standard diagnostic catheterization, more if unusual arterial anatomy is encountered).

All these various pieces come packed in elaborate plastic (polyethylene terephthalate or other polymers) containers, which also come encased in cardboard packaging.

Should angioplasty, stenting, or similar procedure be undertaken, then more catheters are required, such as the plastic "guide" catheters that contain a larger internal lumen to allow passage of angioplasty equipment. An additional quantity of tubing is added to the manifold and stopcock apparatus, as well as a plastic Tuohy-Borst valve to permit rapid entry and exit of various devices into the sheath.

Several new packages of cardboard and plastic are opened which contain the angioplasty balloon, packaging which is usually about 4 feet in length. The stent likewise comes packaged in an 18-inch or so long package with its own elaborate cardboard and plastic housing.

At the conclusion of the procedure, another cardboard/plastic package is opened, this one containing the closure device consisting of several pieces of plastic tubes and tabs.

If the procedure is complicated, the number of catheters and devices used can quickly multiply several-fold.

Beating the Heart Association diet is child's play

21. June 2009 William Davis (19)

In response to the Heart Scan Blog post, Post-Traumatic Grain Disorder, Anne commented:

While on the American Heart Association diet my lipids peaked in 2003. I even tried the Ornish diet for a short time, but found it impossible.

Total Cholesterol: 201
Triglycerides: 263
HDL: 62
LDL: 86

After I stopped eating gluten (I am very sensitive), my lipid panel improved slightly. This past year I started eating to keep my blood sugar under control by eliminating sugars and other grains. Now this is my most recent lab:

Total Cholesterol: 162
Triglycerides: 80
HDL: 71
LDL: 75

Isn't that great? This is precisely what I see in practice: Elimination of wheat and sugars yields dramatic effects on basic lipids, especially reductions in triglycerides of up to several hundred milligrams, increased HDL, reduced LDL.

Beneath the surface, the effects are even more dramatic: reductions or elimination of small LDL particles, reduction or elimination of triglyceride-containing lipoproteins, elimination of the marker for abnormal post-prandial (after-eating) lipoproteins, IDL, reduced c-reactive protein. Add weight loss from abdominal fat stores and reduced blood pressure.

In fact, I would go so far as to speculate that, if the entire nation were to follow Anne's lead and eliminate wheat and sugars, "need" for 30% of all prescription medications would disappear. The incidence of diabetes would be slashed, the U.S. would no longer lead the world in obesity.

Anne and I are not the first to make this observation. It has also been made in several studies, such as:

The Duke University study of low-carbohydrate diets in type II diabetics. In this study, 50% of low-carb participants became non-diabetic: They were cured.

One of the many studies conducted by University of Connecticut's Dr. Jeff Volek, demonstrating dramatic improvement in glucose, insulin (reduced 50%) and insulin responses, and lipids.

Dr. Ron Krauss' early studies that hinted at this effect, even though the "high-fat" diet wasn't really low-carbohydrate.

If wheat and sugar elimination has been shown to achieve all these fabulous benefits, why hasn't the American Heart Association spoken in favor of this dietary approach and other- low-carbohydrate diets ? Why does the American Heart Association maintain its "Check-Mark" stamp of approval on Cocoa Puffs and Count Chocula cereals?

Victim of Post-Traumatic Grain Disorder

20. June 2009 William Davis (14)

Heart Scan Blog reader, Mike, shared his story with me. He was kind enough to allow me to reprint it here (edited slightly for brevity).

Dr. Davis,

I was much intrigued to stumble onto your blog. Heart disease, nutrition, and wellness are critically important to me, because I’m a type 2 diabetic. I’m 53 and was diagnosed as diabetic about 5 years ago, though I suspect I was either diabetic or pre-diabetic 5 years before that. Even in a metropolitan area it's next-to-impossible to find doctors sympathetic to any approach beyond the standard get-the-A1c-below 6.5, get LDL <100, get your weight and blood pressure normal, and take metformin and statins.

I’m about 5’10-and-a-half and when I was young I had to stuff myself to keep weight on; it was an effort to get to 150 pounds, and as a young man, 165 was the holy grail for me. I always felt I’d look better with an extra 10-15 pounds.
I ate whatever I wanted, mostly junk, I guess, in my younger years.

When I hit about age 35, I put on 30 pounds seemingly overnight. As I moved toward middle age I became concerned with the issue of heart health, and around that time Dr. Ornish came out with his stuff. I was impressed that he’d done a
study that supposedly showed measurable decrease in atherosclerotic plaque, and had published the results of his research in peer-reviewed journals. It looked to me as though he had the evidence; who could argue with that? I tried his plan on and off, but as so many people note, an almost-vegan diet is really tough. It was for me, and I could never do it for any length of time. But given that the “evidence” said that I should, I kept trying, and kept beating up on myself when I failed. And I kept gaining weight. I got to almost 200 pounds by the time I was 40 and have a strong suspicion that that’s what caused my blood sugar to go awry, but my doctor at the time never checked my blood sugar, and as a relatively young and healthy man, I never went in very often.

I’ve had bouts of PSVT [paroxysmal supraventricular tachycardia, a rapid heart rhythm] every now and again since I was 12 or so. I used to convert the rhythm with Valsalva, but as I moved into my forties, occasionally my blood pressure would be elevated and it made me nervous to do the procedure because it was my understanding that it spikes your blood pressure when you do it. So I began going to the ER to have the rhythm converted, which they do quite easily with adenosine. On one of my infrequent runs to the ER to get a bout of PSVT converted, they discovered my blood glucose was 500 mg/dL, and I’d never experienced any symptoms! They put me in the hospital and gave me a shot of insulin, got it town to 80 mg/dL easily,
diagnosed me as diabetic, and put me on 500 mg. metformin a day.

I was able to get my A1c down to 7, then down to 6.6, and about that time I read a number of Dr. Agatston’s books, and began following the diet, and pretty quickly got my A1c down to 6.2, and my weight down, easily, to 158. That was fine with my doctor; he acted as though I was in good shape with those numbers. Soon I ran into Dr. Bernstein’s material, and came face to face with a body of research that suggested I needed to get the A1c down to below 5! That was both discouraging and inspiring, and frankly it’s been difficult for me to eat as lo-carb as I appear to need to, so I swing back and forth between 6.2 and 6.6. I know I need to work harder, be more diligent in my carb control, and I see with my meter that if I eat low-carb I have great postprandial and fasting blood sugars, but since I don’t particularly get any support or encouragement from
either my doctor or my wife for being so “radical,” it’s hard to pass the carbs by.

One thing that always confused me was that though I saw on my meter that BG [blood glucose] readings were better with a lo-carb diet, and though I saw the preliminary research suggesting that lo-carb could be beneficial in controlling CVD, I didn’t understand why Ornish had peer-reviewed research demonstrating reversal of atherosclerosis on a very-lowfat diet. How could two opposing approaches both help? I wondered if it were possible that one diet is good for diabetes, and the
other good for heart health. That would mean diabetics are screwed, because they always seem to end up with heart disease.

From time to time I’d look for material that explained this seeming contradiction. I was determined to try to stay lo-carb, simply because I saw how much better my blood sugars are when I eat lo-carb; but it’s hard in the face of this or that website that tells you about all the dangers of a lo-carb diet and that touts the lo-fat approach. That tends to be the conventional wisdom anyway.

Finally in one of those searches I came across your material, and saw you offer what was at last an explanation of what Ornish had discovered--it wasn’t a reversal of atherosclerotic plaques he was seeing; it was that his diet was improving endothelial dysfunction in people who had had high fat intakes.

Odd as it may seem to you, that little factlet has been enough to allow me to discard entirely the lingering ghost of a suspicion that I ought to be eating very-lowfat. In fact, I was very excited to see your claim that your approach can reverse atherosclerotic plaque.

It would be nice to find a doctor who’d be supportive of your approach. My doctor isn’t much interested in diet or
nutrition. He just wants my weight in the acceptable range, my blood pressure good, and my LDL 100 or below (which I know isn’t low enough). He’s not particularly interested in getting a detailed lipid report. I hope I can talk him into ordering one so that it’s more likely I can get it covered by my insurance.

I very much appreciated the links you gave to Jenny’s diabetes websites, and I’ve resolved to get even better control of my BG by being more diligent with my diet. I’m planning on joining your site, reading your book, and following your advice. I just have this sort of deflating feeling that it would have been better if I’d stumbled upon this before I had diabetes. Still, it’s nice to have a site that offers to laypeople the best knowledge available concerning how to take care of their heart.

Mike is yet another "victim" of the "eat healthy whole grains" national insanity, the Post-Traumatic Grain Disorder, or PTGD. The low-fat dietary mistake has left many victims in its wake, having to deal with the aftermath of corrupt high-carbohydrate diets: diabetes, heart disease, and obesity.

We should all hope and pray that "low-fat, eat healthy whole grains" goes the way of Detroit gas guzzlers and sub-prime mortgages.

Drug industry "Deep Throat"

18. June 2009 William Davis (16)

A Heart Scan Blog reader brought the following letter from a former pharmaceutical sales representative to congress to my attention.

Interesting excerpts:

As a former drug representative for Eli Lilly, I spent 20 months increasing the market share of my company’s drugs. I was recruited fresh from college with an eager desire to employ my degree in molecular biology and biochemistry. Shortly after my hiring, it became clearly apparent that a drug sale had much more to do with establishing personal relationships than it did with understanding the latest science. However, any doubts I held regarding the effectiveness of such methods were dispelled by the results of my persuasiveness and the financial rewards I received for my efforts. The latter also helped me rationalize the many ethically dubious situations I routinely encountered in my work. Upon my departure from the industry, I began working for the public’s health. Seven years later, as a result of my experiences and education I am more convinced than ever that the goals of the pharmaceutical industry often stand in direct conflict with the practice of ethical and responsible medicine. Nothing in my recent research causes me to believe that my experiences were anything but typical of the training and practice of the majority of drug reps plying their trade today.

“There’s a big bucket of money sitting in every [doctor’s] office.” – Michael Zubillaga, Astra Zeneca Regional Sales Director, Oncology

The majority of drug reps entering the work force today are young and attractive. The ranks of reps are replete with sexual icons: former cheerleaders, ex-military, models, athletes. Of course, as a sales job, the reps must be eloquent and convincing. Depending on the population, certain ethnicities are preferred either to make the rep distinct among other reps or to provide them with a cultural advantage in connecting with their clients. Noticeably lacking among most new reps is any significant scientific understanding. My personal case illustrates this point rather vividly: In my training class for Eli Lilly's elite neuroscience division, selling two products that constituted over 50% of the company's profits at the time, none of my 21 classmates nor our two trainers had any college level scientific education. In fact, that first day of training, I taught my class and my instructors the very basic but crucial process by which two nerve cells communicate with one another. It is very likely that the majority of my class couldn't explain the difference between a neuron and a neutron prior to sales school. While it's certainly a bonus to have a scientifically educated representative, it is far from a primary recruitment criterion. Youth is a much higher criterion for the sales position.

Sales representative trainers are almost always veteran sales representatives and consequently, much of the training they offer is implicit in the anecdotes they give. This informal training parallels the standard training offered by the industry and in many ways compliments it. It is tacitly accepted by management and perceived as the "real" training by many veteran sale representatives. Among the more dubious "unofficial" lessons a new rep learns are: how to manipulate an expense report to exceed the spending limit for important clients, how to use free samples to leverage sales, how to use friendship to foster an implied "quid pro quo" relationship, the importance of sexual tension, and how to maneuver yourself to becoming a necessity to an office or clinic.

The most troubling aspect of pharmaceutical sales is systematic befriending of our clients. In addition to the psychological profiling mentioned above, drug reps are taught to constantly be on the lookout for personal effects that will help us connect to our doctors. When entering an office for the first time, we nonchalantly survey it for clues to ingratiate ourselves with our client. Similarly, conversations are intentionally steered into the realm of personal details such as religion, family, or hobbies to acquire similar information. As a matter of training, we collect this data subtly. In the course of a conversation with clients, we may glean facts about their prescribing preferences, the dates of their children’s birthdays, where they were born, or what music they enjoy. Training encourages us to commit these details to memory just long enough to return to our cars and instantly type up a “call report” listing the details of our conversation. On a daily basis, we connect our computers to a central database that uploads the information we’ve acquired, allowing us to share it with our partner drug reps and company marketers. Subsequently, drug reps interweave pieces of conversation specifically tailored to appeal to their client drawn from personal information that wasn’t necessarily shared with them. For example, Dr. Jones will be nothing but grateful when I supply him with a cake celebrating his children’s birthday when, in fact, he told my partner (and not me) the birthdates several months prior in a personal conversation.

The writer's comments ring true: The relentless attention-grab of sales representatives, using clever tactics that include access to detailed records of physician prescribing habits, big smiles and eye-winking, are detailed perfectly.

There's nothing wrong with a business doing its job by marketing its products and services. What is so wrong about this picture is that one side is so well-equipped, heavily funded, with access to extraordinary resources that the other side (physicians) don't have. And the physicians aren't the victims--YOU are.

A middle-aged, receding hairline physician, faced with a 28-year old attractive woman asking all manner of ingratiating questions but knowing full well what she is doing, having strategized for weeks on how to manipulate the behavior of her "mark," is helpless.

Like the mortgage-backed security crisis, we've reached another phenomenon of crisis proportions. Direct-to-consumer drug advertising, drugs for non-conditions and well people, pinpoint marketing of drugs to physicians--it's all gone too far.

Personally, drug representatives are not welcome in my office. This generally prompts puzzled, followed by angry, looks from the representatives, often traveling with a district supervisor hoping to help polish their pitch. If patients didn't request free samples, the reps would not step foot in the office.

Triglyceride Buster-Update

17. June 2009 William Davis (8)

In the last Heart Scan Blog post, I described Daniel's experience reducing his triglycerides from 3100 mg/dl to around 1100 mg/dl with use of omega-3 fatty acids from fish oil, along with modifications in his diet. This was accomplished in the space of around two weeks.

An update: Daniel has continued another 10 days on his fish oil, along with elimination of wheat, cornstarch, and sugars.

Repeat triglyceride: 202 mg/dl. That's 93.5% reduction in the space of three weeks--no drugs involved.

Daniel really did nothing extraordinary. He simply followed the simple advice I provided to take a moderate dose of EPA+DHA from over-the-counter fish oil supplements, along with elimination of the foods that are extravagant triggers of triglycerides.

He's got just a little further to go to achieve the biologically ideal level of less than 60 mg/dl. You can see that it is not really that difficult--provided someone didn't load you down with nonsense about "cutting your fat," or statin or fibrate drugs.

Triglyceride buster

16. June 2009 William Davis (24)

Two weeks ago, Daniel started with a triglyceride level of 3100 mg/dl, a dangerous level that had potential to damage his pancreas. The inflammatory injury incurred could leave him with type I diabetes and inability to digest foods, since the insulin-producing capacity and the enzyme producing capacity of the pancreas are lost.

Daniel added 3600 mg of omega-3s per day. Within 10 days, his triglycerides dropped nearly 2000 mg to just over 1100 mg/dl--still too high, but an incredible start.

The power of omega-3 fatty acids from fish oil to reduce triglycerides is illustrated most graphically by people with a condition called "familial hypertriglyceridemia" that is responsible for triglyceride levels of 500, 1000, even several thousand milligrams. That's what Daniel has. Given appropriate doses of omega-3s, triglycerides drop hundreds, even thousands, of milligrams.

No question: Omega-3 fatty acids from fish oil are the best tool available for reduction of triglycerides. The effect is dose-dependent, i.e., the more you take, the greater the triglyceride reduction.

How omega-3s exerts this effect is unclear, though there is evidence to suggest that omega-3s suppress several nuclear receptors involved in triglyceride (VLDL) production and increase the expression or activity of the enzyme lipoprotein lipase, an enzyme that clears triglycerides from the blood.

I am continually surprised at the number of people with high triglycerides who are still treated with a fibrate drug, like Tricor, or a statin drug, when fish oil--widely available, essentially free of side-effects, with a proven cardiovascular risk-reducing track record--should clearly be the first choice by a long stretch.

Among its many benefits, omega-3 fatty acids from fish oil also:

Reduce matrix metalloproteinases (MMP)--Two fractions of MMPs, MMP-2 and MMP-9, are inflammatory enzymes present in atherosclerotic plaque that are suspected to trigger plaque "rupture." Omega-3s have been shown to reduce both forms of MMP.

Block uptake of lipids in the artery wall--Suggested by a study in mice.

Modify postprandial responses--In the first few hours after eating (the "postprandial" period), a flood of digestive byproducts of a meal are present in the bloodstream. While research exploring postprandial effects is still in its infancy, it is clear that omega-3 fatty acids have the capacity to favorably modify postprandial patterns. One common surrogate measure for postprandial abnormalities is intermediate-density lipoprotein, or IDL, that we obtain in fasting blood through lipoprotein panels like NMR and VAP. With sufficient omega-3s alone, IDL is completely eliminated.

Unfortunately, most of my colleagues, if they even think to use omega-3s, choose to use the prescription form, Lovaza. Indeed, several representatives from AstraZeneca, the pharmaceutical outfit now distributing this miserably overpriced product, frequently barge their way into my office poking fun at our use of nutritional supplements instead of the prescription Lovaza. "But insurance covers it in most cases!" they plead. "And your patients will know that they're getting the real product, not some fake. And they'll have to take fewer capsules!"

I never use Lovaza to reduce triglycerides, even in familial hypertriglyceridemia--the FDA-approved indication for Lovaza--and have not yet seen any failures, only successes.

Newsweek, Time, and other fronts for the drug industry

15. June 2009 William Davis (0)

I used to believe that conventional print media--newspapers, magazines--were unbiased, untouchable flames of truth. Perhaps there was a time when this was true, when the young reporter, eager to change the world, uncovered the story that righted some huge wrong.

Those days are drawing to a close.

Today, the once powerful print media are collapsing due to the competition of the cheaper, broader reach of the internet.

Jogging does NOT cause heart disease

14. June 2009 William Davis (20)

Periodically, I'll come across a knuckleheaded report like this one from Minneapolis:

Marathon Man’s Heart Damaged by Running?

Of course, the obligatory story about how a cardiologist came to the rescue and "saved his life" with a stent follows. In other words, a stent purportedly saved the life of this vigorous man with no symptoms and high capacity for exercise.

Does vigorous exercise, whether it's marathon running, long-distance biking, or triathlons, cause coronary disease? Should all vigorous athletes run to their doctor to see if they, too, need their lives to be "saved."

Let me tell you what's really going on here. People with the genetic pattern lipoprotein(a), or Lp(a), tend to be slender, intelligent and athletic. For genetic reasons, these people gravitate towards endurance sports like long-distance running. Lp(a) is a high-risk factor for coronary disease. It is the abnormality present in the majority of slender, healthy people who are shocked when they receive a high heart scan score or have a heart attack or receive a stent. (I call Lp(a) "the most aggressive known coronary risk factor that nobody's heard about.")

The association between endurance exercise and heart disease is just that: an association. It does not mean that exercise is causal. Having seen coronary plaque detected with heart scans in many runners, virtually all of whom demonstrated increased Lp(a), I believe that Lp(a) is causal.

Unfortunately, the man in the Minneapolis story, now that his life is "saved," will likely be advised to take a statin drug and follow a low-fat diet . . . you know, the diet that increases Lp(a).

Warning: Your pharmacist may be hazardous to your health

12. June 2009 William Davis (24)

Pharmacists can be very helpful resources when it comes to questions about prescription drugs.

The operant word here is drugs.

What they are most definitely not expert on are nutritional supplements. In fact, a day doesn't pass by without having to dispell one falsehood or another conveyed to a patient about a nutritional supplement by a pharmacist.

Among the more common falsehoods told to patients by pharmacists:

"You have to take Niaspan. Sloniacin doesn't work."

Patent nonsense. A few years back, I was the largest prescriber of Niaspan in Wisconsin. Although I am embarassed to admit it, I also spoke for the company, educating fellow physicians on the value of niacin for correction of lipid disorders.

Then I shifted to Sloniacin due to cost--it costs 1/20th the cost of prescription Niaspan. I examined the pharmacokinetic data (pattern of release in the body), the published literature (e.g., the famous HATS Trial), and have used Sloniacin over 1000 times in patients. In my experience, there is no difference: no difference in efficacy, no difference in safety, no difference in side-effects. There is a BIG difference in price.

Unfortunately, most pharmacists get their information on niacin from the Niaspan representative.

"You shouldn't be taking vitamin D supplements. I have prescription vitamin D here."

What the pharmacist means is that you should replace your vitamin D3, or cholecalciferol--the form recognized as vitamin D by the human body--with the plant form of vitamin D, vitamin D2 or ergocalciferol.

Since when is a plant form of a hormone (vitamin D is a potent hormone, not a vitamin; it was misnamed) better than the human form?

I've previously talked about this issue in a blog post called Vitamin D for the pharmaceutically challenged.

The notion that D2 is somehow superior to the real thing, D3, is absurd. I use D3 only in my practice and have checked blood levels thousands of times. As long as the D3 comes as a gelcap, drops, or powder in a capsule, it works great, yielding predictable and substantial increases in blood levels of 25-hydroxy vitamin D. If it comes as prescription D2 (or over-the-counter D2), I have seen many failures: no increase in blood levels of vitamin D or meager increases.

Prescription status is no guarantee of effectiveness.

"Why do you need iodine? You already get enough from food."

The NHANES data over the last 25 years argue otherwise: Iodine deficiency is growing, particularly as people are avoiding iodized salt and the iodine content of processed foods is diminishing. The explosion in goiters in my office also suggest this is no longer a settled issue.

On the positive side, it is exceptionally easy to remedy with an inexpensive iodine supplement. That is, until the pharmacist intervenes and injects his bit of nutritional mis-information.

I'm not bashing pharmacists. In fact, Track Your Plaque's own Dr. BG has a pharmacy background, and she is an absolute genius with nutritonal supplements. But she is a rare exception to the rule: Most pharmacists know virtually nothing about nutritional supplements. You might as well ask your hairdresser.

"Healthy" people are the most iodine deficient

5. June 2009 William Davis (27)

Ironically, the healthiest people are the most likely to be deficient in iodine.

Why?

Healthy people tend to:

--Avoid iodized salt because of public health advice to limit sodium
--Use sea salt to obtain minerals like magnesium--but sea salt contains little iodine
--Limit meat--Carnivores obtain more iodine than vegetarians or vegans. In one study, up to 80% of vegans were iodine-deficient (Krajcovicova-Kudlackova M et al 2003).
--Exercise--Substantial amounts of iodine are lost through sweating. In a study of high school soccer players, 38.5% were severely iodine deficient, compared to 2% of sedentary students (Mao IF et al 2001).

That is indeed what I am seeing in my office, as well: The healthiest, most attentive to healthy eating, and most physically active are the ones showing up with small goiters (enlarged thyroid glands) and increased TSH and low free T4 levels.

Why am I checking thyroid and talking about iodine? Because even the smallest degree of thyroid dysfunction can double, triple, or quadruple your risk for cardiovascular events. See the posts Is normal TSH too high? and Thyroid perspective update.

What kind of iodine do you take?

4. June 2009 William Davis (21)

The results of the latest Heart Scan Blog poll are in.

204 respondents answered the question:

Do you take an iodine supplement?

The responses:

Yes, I take Iodoral, Lugol's, or SSKI
26 (12%)

Yes, I take potassium or sodium iodide
19 (9%)

Yes, I take kelp tablets or powder
64 (31%)

No, I rely on generous use of iodized salt
23 (11%)

No, I don't supplement iodine at all
66 (32%)

Isn't iodine something you put on cuts and scratches?
6 (2%)

I am heartened by the number of respondents taking iodine in some form. After all, iodine is an essential trace mineral. Without it and health suffers, often dramatically.

However, I am concerned by the percentage of people who don't supplement iodine at all: 32%. Interestingly, this is approximately the proportion of people who come to my office who also do not supplement iodine who are now showing goiters, or enlarged thyroid glands due to iodine deficiency. Goiters lead to hypothyroidism (low thyroid hormone levels), followed by hyperactive nodules, not to mention undesirable effects like weight gain, fatigue, hair loss, constipation, intolerance to cold, higher LDL cholesterol and triglycerides, and heart disease.

11% of respondents report using lots of iodized salt. This may or may not be sufficient to provide enough iodine to prevent goiter and allow normal thyroid function. The success of this strategy depends to a great extent on how often salt is purchased. Salt that sits on the shelf for more than a month is devoid of iodine, given iodine's volatility.

I am also favorably impressed by the number of people who take "serious" iodine supplements like Lugol's solution, Iodoral, or SSKI. Of course, people who read The Heart Scan Blog tend to be an unusually informed, healthy population. The 12% of people in the poll who take these forms of iodine does clearly not mean that 12% of the general population also takes them. But 12% is more than I would have predicted.

On the Track Your Plaque website, we are awaiting an interview with iodine expert, Dr. Lyn Patrick. I'm hoping for some juicy insights.
