China fiction?

10. July 2010 William Davis (39)

Dr. Colin Campbell caused a stir with publication of his 2005 book, The China Study. Dr. Campbell, after extensive animal and epidemiologic research conducted in China over 20 years, concluded that a diet high in animal protein, especially casein, was associated with increased cancer, osteoporosis, and heart disease risk.

Richard Nikoley of Free the Animal and Stephan Guyenet of Whole Health Source have been talking about an analysis of the China Study raw data performed by a young woman named Denise Minger.

Denise's analysis is nothing short of brilliant, absolutely "must" reading for anyone interested in nutrition.

Her comments on the relationship of wheat to heart disease:

Why does Campbell indict animal foods in cardiovascular disease (correlation of +1 for animal protein and -11 for fish protein), yet fail to mention that wheat flour has a correlation of +67 with heart attacks and coronary heart disease, and plant protein correlates at +25 with these conditions?

Speaking of wheat, why doesn’t Campbell also note the astronomical correlations wheat flour has with various diseases: +46 with cervix cancer, +54 with hypertensive heart disease, +47 with stroke, +41 with diseases of the blood and blood-forming organs, and the aforementioned +67 with myocardial infarction and coronary heart disease?

Carbohydrate-LDL double whammy

9. July 2010 William Davis (14)

Carbohydrates in the diet trigger formation of small LDL particles. Because carbohydrates, such as products made from wheat, increase triglycerides and triglyceride-containing lipoproteins (chylomicrons, chylomicron remnants, VLDL, and IDL), LDL particles (NOT LDL cholesterol) become triglyceride-enriched. Triglyceride-enriched LDL particles are "remodeled" by the enzyme, hepatic lipase, into triglyceride-depleted, small LDL particles.

The list of reasons why small LDL particles are more atherogenic, i.e., plaque-causing, is long:

--Small LDL particles, being smaller, more readily penetrate the endothelial barrier of the arterial wall.
--Small LDL particles are more adherent to glycosaminoglycans in the artery wall.
--Small LDL particles are poorly taken up by the liver LDL receptor, but enthusiastically taken up by macrophage receptors of the sort in your artery walls.
--Because of their poor liver clearance, small LDL persists in the bloodstream far longer than large LDL.
--Small LDL particles are more oxidation-prone. Oxidized LDL are more likely to trigger inflammatory phenomena and be taken up by macrophages in the artery wall.

Let me add another reason why small LDL particles are more likely to cause plaque: They are more likely to undergo glycation. (More on glycation here.)

Glycation occurs when glucose (sugar) molecules in the blood or tissue modify proteins, usually irreversibly. Small LDL particles are uniquely glycation-prone. (This is likely due to a conformational change of the apoprotein B in the small LDL particle, exposing lysine residues along apo B that become glycated.)

Here's a great demonstration of this phenomenon by Younis et al:

"LDL3" is the small type. Note that small LDL particles are 4-5 times more glycated than large LDL. That's a big difference.

Once glycated, small LDL is especially resistant to being taken up by the liver. Like annoying in-laws, they hang around and hang around and . . . The longer they hang around, they more opportunity they have to contribute to plaque formation.

So, carbohydrates trigger formation of small LDL particles. Once formed, small LDL particles are glycated when blood sugar increases. While LDL can be glycated even when blood sugars are in the normal range (90 mg/dl or less), glycation goes berserk when blood sugars go higher, such as a blood sugar of 155 mg/dl after a bowl of steel-cut oatmeal.

To lose weight, prick your finger

8. July 2010 William Davis (45)

We know that foods that trigger insulin lead to fat storage. Putting a stop to this process allows you to mobilize fat and lose weight. If you're starting out from scratch, rapid and dramatic weight loss can be experienced, as much as one pound per day.

So how can you stop triggering insulin?

The easiest way is to eliminate, or at least minimize, carbohydrates. My favorite method to restrict carbohydrates is to eliminate wheat and minimize exposure to other carbohydrates, such as oats, cornstarch, and sugars. All these foods, wheat products worst of all, cause blood sugar and insulin to skyrocket.

Another way is to check your blood sugar one hour after completing a meal and keep your after-eating, or "postprandial," blood sugar 100 mg/dl or less. Let's say you are going to eat stone ground oatmeal, for example. Blood sugar prior to eating is, say, 90 mg/dl. One hour after oatmeal it's 168 mg/dl--you know that this is going to trigger insulin and make you fat. Oatmeal should therefore be eliminated.

Keeping blood sugar to 100 mg/dl or less after eating teaches you how to avoid provocation of insulin. A shrinking tummy will follow.

To do this, you will need:

1) A glucose meter--My favorite is the One Touch Ultra Mini ($13.42 at Walmart). It's exceptionally easy to use and requires just a dot of blood. Drawback: Test strips are about $1 each. Accuchek Aviva is another good device. (We've had a lot of problems with Walgreen's brand device.)
2) Test strips--This is the costly part of the proposition. Purchased 25 or 50 at a time, they can cost from $0.50 to $1.00 a piece.
3) Lancets--These are the pins for the fingerstick device that comes with the glucose meter. A box should be just a few dollars.

No prescription is necessary, nor will insurance pay for your costs unless you're diabetic. To conserve test strips, use them only when a new, untested food or food combination is going to be consumed. If you had two scrambled eggs with green peppers, sundried tomatoes, and olive oil yesterday and had a one hour postprandial glucose of 97 mg/dl, no need to check blood sugar again if you are having the same meal again today.

Iodine update

2. July 2010 William Davis (30)

As the iodine experience grows, I've made several unique observations.

Up to several times per day, I see people who are responding in some positive way to iodine supplementation. (See previous Heart Scan Blog posts about iodine: Iodine deficiency is REAL and The healthiest people are the most iodine deficient.)

Among the phenomena I've observed:

1) A free T4 thyroid hormone at the low end of normal, or even in the below normal range, along with a highish TSH (usually >1.5 mIU/L) are the most frequent patterns that signal iodine deficiency. Occasionally, a low free T3 value will also increase, though this is the least frequent development.

2) At a dose of 500 to 1000 mcg iodine per day, it requires anywhere from 3 to 6 months to obtain normalization of thyroid measures.

3) Reversal of small goiters also occurs over about 6 months.

4) Iodine intolerance is uncommon. If it occurs, using a low starting dose, e.g., 100-200 mcg per day, usually works. The dose can be increased gradually over the ensuing months.

5) Perceptible benefits of iodine occur only occasionally. The most common perceptible effects are increased energy and increased warmth, especially of the hands and feet.

6) Some people who have taken thyroid hormones for years will develop reduced need for their medication with iodine supplementation. In other words, their physician was inadvertently treating iodine deficiency with thyroid hormone replacement. Anyone already on any thyroid preparation(s), e.g., Synthroid, levothyroxine, Armour thyroid, Naturethroid, etc., should watch for signs of hyperthyroidism when iodine is added. But having your own thyroid gland make its own thyroid hormones is better and healthier than relying on the prescription agents. Just be sure to monitor your thyroid measures.

7) Iodine toxicity can occur--Two people in my clinic population developed iodine toxicity by taking 6000 mcg iodine per day for 6 or more months. (Both patients did it on their own based on something they read). Iodine toxicity is evidenced by shutting down your thyroid, i.e., marked increase in TSH, e.g., 15 mIU/L.

Most of the people in my clinic obtain their iodine from kelp tablets. Some use potassium iodine (KI) drops. A handful have used the high-potency Iodoral (12.5 mg or 12,500 mcg iodine per tablet); this was also the form that generated the toxic effects in the two females.

All in all, iodine deficiency is actually far more common than I ever suspected. Not everybody is iodine deficient. But a substantial minority of the Midwest population I see certainly are.

Why haven't you heard about lipoprotein(a)?

1. July 2010 William Davis (26)

Lipoprotein(a), or Lp(a), is the combined product of a low-density lipoprotein (LDL) particle joined with the liver-produced protein, apoprotein(a).

Apoprotein(a)'s characteristics are genetically-determined: If your Mom gave the gene to you, you will have the same type of apoprotein(a) as she did. You will also share her risk for heart disease and stroke.

When apoprotein(a) joins with LDL, the combined Lp(a) particle is among the most aggressive known causes for coronary and carotid plaque. If apoprotein(a) joins with a small LDL, the Lp(a) particle that results is especially aggressive. This is the pattern I see, for instance, in people who have heart attacks or have high heart scan scores in their 40s or 50s.

Lp(a) is not rare. Estimates of incidence vary from population to population. In the population I see, who often come to me because they have positive heart scan scores or existing coronary disease (in other words, a "skewed" or "selected" population), approximately 30% express substantial blood levels of Lp(a).

Then why haven't you heard about Lp(a)? If it is an aggressive, perhaps the MOST aggressive known cause for heart disease and stroke, why isn't Lp(a)featured in news reports, Oprah, or The Health Channel?

Easy: Because the treatments are nutritional and inexpensive.

The expression of Lp(a), despite being a genetically-programmed characteristic, can be modified; it can be reduced. In fact, of the five people who have reduced their coronary calcium (heart scan) score the most in the Track Your Plaque program, four have Lp(a). While sometimes difficult to gain control over, people with Lp(a) represent some of the biggest success stories in the Track Your Plaque program.

Treatments for Lp(a) include (in order of my current preference):

1) High-dose fish oil--We currently use 6000 mg EPA + DHA per day
2) Niacin
3) DHEA
4) Thyroid normalization--especially T3

Hormonal strategies beyond DHEA can exert a small Lp(a)-reducing effect: testosterone for men, estrogens (human, no horse!) for women.

In other words, there is no high-ticket pharmaceutical treatment for Lp(a). All the treatments are either nutritional, like high-dose fish oil, or low-cost generic drugs, like liothyronine (T3) or Armour thyroid.

That is the sad state of affairs in healthcare today: If there is no money to be made by the pharmaceutical industry, then there are no sexy sales representatives to promote a new drug to the gullible practicing physician. Because most education for physicians is provided by the drug industry today, no drug marketing means no awareness of this aggressive cause for heart disease and stroke called Lp(a). (When a drug manufacturer finally releases a prescription agent effective for reducing Lp(a), such as eprotirome, then you'll see TV ads, magazine stories, and TV talk show discussions about the importance of Lp(a). That's how the world works.)

Now you know better.

How to have a heart attack in 10 easy steps

29. June 2010 William Davis (48)

If you would like to plan a heart attack in your future, here are some easy-to-follow steps to get you there in just a few short months or years:

1) Follow a low-fat diet.

2) Replace fat calories with "healthy whole grains" like whole wheat bread.

3) Eat "heart healthy" foods like heart healthy yogurt and breakfast cereals from the grocery store.

4) Use cholesterol-reducing plant sterols.

5) Take a multivitamin to obtain all the "necessary" nutrients.

6) Take the advice of your doctor who declares your heart "in great shape" based on your cholesterol values.

7) Take the advice of your cardiologist who declares your heart "like that of a 30-year old" based on a stress test.

8) Take a statin drug to reduce LDL and c-reactive protein while maintaining your low-fat diet.

9) Neglect sun exposure and vitamin D restoration.

10) Limit your salt intake while not supplementing iodine.

There you have it: An easy, 10-step process to do your part to help your local hospital add on its next $40 million heart care center.

If you would instead like to prevent a heart attack in your future, then you should consider not doing any of the above.

Kick inflammation in the butt

25. June 2010 William Davis (0)

C-reactive protein, or CRP, is a protein produced by the liver in response to inflammatory signals its receives. Thus, CRP has emerged as a popular measure to gauge the underlying inflammatory status of your body. Higher CRP levels (e.g., 3.0 mg/L or greater) are associated with increased risk of heart attack and other cardiovascular events.

The drug cartel have jumped on this with the assistance of Harvard cardiologist, Dr. Paul Ridker. Most physicians now regard increased CRP as a mandate to institute statin therapy, preferably at high doses based on such studies as The JUPITER Trial, in which rosuvastatin (Crestor), 20 mg per day, reduced CRP 37%.

I see this differently. Two strategies drop CRP dramatically, nearly to zero with rare exception: Vitamin D restoration and wheat elimination. Not 37%, but something close to 100%.

Yes, I know it sounds wacky. But it works almost without fail, provided the rest of your life is conducted in reasonably healthy fashion, i.e., you don't live on Coca Cola, weigh 80 lbs over ideal weight, and smoke.

How can something so easily reduced like CRP mean you "need" medication? Easy: Increased CRP means there are fundamental deficiencies and/or inflammation provoking foods in your diet. Correct neither and there is an apparent benefit to taking a statin drug.

Why not just correct the underlying causes?

Life without Lipitor

25. June 2010 William Davis (17)

One of the most common reasons people come to my office is to correct high cholesterol values without Lipitor. (Substitute "Lipitor" with Crestor, simvastatin, Vytorin, or any of the other cholesterol drugs; it's much the same.)

In the world of conventional healthcare, in which you are instructed to follow a diet that increases risk for heart disease and not advised to correct nutrient deficiencies like vitamin D and omega-3 fatty acids, then a drug like Lipitor may indeed provide benefit.

But when you are provided genuinely effective information on diet, along with correction of nutrient deficiencies, then the "need" and apparent benefits of Lipitor largely dissolve. While there are occasional genetic anomalies that can improve with use of Lipitor and other statins, many, perhaps most, people taking these drugs really would not have to if they were just provided the right information.

Anyone following the discussions on these pages knows that wheat elimination is probably one of the most powerful overall health strategies available. Wheat elimination reduces real measured LDL quite dramatically. Provided you limit other carbohydrates, such as those from fruits, as well, LDL can drop like a stone. That's not what your doctor tells you. This approach works because elimination of wheat and limiting other carbohydrates reduces small LDL. Small LDL particles are triggered by carbohydrates, especially wheat; reducing carbohydrates reduces small LDL. Conventional LDL of the sort obtained in your doctor's office will not show this, since it is a calculated value that appears to increase with reduced carbohydrates, a misleading result.

Throw vitamin D normalization and iodine + thyroid normalization into the mix (both are exceptionally common), and you have two additional potent means to reduce (measured) LDL. Not restricting fat but increasing healthy fat intake, such as the fats in lots of raw nuts, olive oil, and flaxseed oil reduce LDL.

While I still prescribe statins now and then, a growing number of people are succeeding without them.

(Note that by "measured" LDL I am referring to the "gold standard," LDL particle number by NMR provided by Liposcience. A second best is measured Apoprotein B available through most conventional labs.)

In search of wheat: Emmer

23. June 2010 William Davis (13)

While einkorn is a 14-chromosome ancient wheat (containing the so-called "A" genome), emmer is a 28-chromosome wheat (containing the "A" and "B" genomes, the "B" likely contributed by goat grass 9000 years ago).

Both einkorn and emmer originally grew wild in the Fertile Crescent, allowing Neolithic Natufians to harvest the wild grasses with stone sickles and grind the seeds into porridge.

Having tested einkorn with only a modest rise in blood sugar but without the gastrointestinal or neurological effects I experienced with conventional whole wheat bread, I next tested bread made with emmer grain.

The emmer grain was ground just like the other two grains, cardiac dietitian Margaret Pfeiffer doing all the work of grinding and baking. Margaret added nothing but water, yeast, and a little salt. The emmer rose a little more than einkorn, but not to the degree of conventional whole wheat.

I tested my blood sugar beforehand: 89 mg/dl. I then ate 4 oz of the emmer bread. It tasted very similar to conventional whole wheat, but not as nutty as einkorn. Also not as heavy as einkorn, only slightly heavier than conventional whole wheat.

One hour later, blood sugar: 147 mg/dl. I felt slightly queasy for about 2-3 hours, but that was the end of it. No abdominal cramps, no sleep disturbance or crazy dreams, no nausea, no change in ability to concentrate.

I asked four other wheat-sensitive people to try the emmer bread. Likewise, nobody reacted negatively (though nobody tested blood sugar).

So it seems to me, based on this small, unscientific experience, that ancient einkorn (A) and emmer (AB) wheat seem to act like carbohydrates, similar to, say, rice or quinoa, but lack many of the other adverse effects induced by conventional wheat.

Modern wheat , Triticum aestivum, contains variations on the "A," "B," and "D" genomes, the "D" contributed by hybridization with Triticum tauschii at about the same time that emmer wheat hybridization occurred. It is likely that proteins coded by the "D" genome are the source of most of the problems with wheat products: immune, neurologic, gastrointestinal destruction, airway inflammation (asthma), increase in appetite, etc. This is consistent with observations made in studies that attempt to pinpoint the gliadin proteins that trigger celiac, the area in which much of this research originates.

If I ever would like an indulgence of cookies or cupcakes, I think that I will order some more einkorn grain from Eli Rogosa.

In search of wheat: Another einkorn experience

23. June 2010 William Davis (6)

Lisa is a trained dietitian. Unlike many of her colleagues, she has "seen the light" and realized that the conventional advice that most dietitians are forced to dispense through hospitals, clinics, and other facilities is just plain wrong.

I know Lisa personally and we've had some great conversations on diet and nutritional supplements. I told Lisa about my einkorn experience and how I witnessed a dramatic difference between bread made from einkorn wheat and that made from conventional whole wheat. So she decided to give it a try herself.

Here's Lisa's experience:

This past Friday, June 18th, I conducted my "Einkorn Wheat Experiment".

7 am
FBG [fasting blood glucose] 97 mg/dl

8 am-9 am
1 hour high-intensity aerobic workout

10:05 am
BG 99

10:05 am
I embarked upon the journey of choking down, I mean enjoying, the hefty piece of Einkorn bread. Wow, was that bread dense! It was a lot of work chewing.

10:50 am
(45 minutes after consumption, wanted to see what BG did a bit before the 1 hr mark) BG 153

11:05 am
1hr PP 120

11:35 am
90 mins PP [postprandial] 113

12:05 pm
2 hours PP 114 ... at this time I ate an egg & veggie omelet for lunch.

12:50 pm
BG 100

Before dinner 5:10 pm
BG 88

I was surprised with the BG of 153. However, it was good to see my insulin response is reactive and decreased BG 33 points in 15 minutes to end up with a BG of 120 1 hr after the bread.

So, it appears my response is similar. A slight elevation of BG at the 1 hour mark, but not to the degree of conventional whole grain wheat bread.

Of note, also, was the fact that I cannot remember the last time I ate a piece of wheat bread of this magnitude that did not make me bloated... not at all: No cramps, no brain fog, no headache and, did I mention not bloated?

I believe you are on to something with tolerance of Einkorn wheat for those of us with wheat sensitivities, in addition to its apparent lower glycemic response.

Along with Lisa, I asked four other people with various acute intolerances (all gastrointestinal) to conventional wheat, i.e., people who experience undesirable effects from wheat within minutes to several hours, to eat the einkorn bread. None experienced their usual reactions.

Obviously, this does not constitute a clinical trial. Nonetheless, I find this a compelling observation: People like myself who generally experience distinct undesirable reactions to wheat did not experience these reactions with einkorn.

Note, however, that einkorn behaves like a carbohydrate. No different, say, from brown rice or quinoa. However, unlike modern whole wheat flour from Triticum aestivum, in this little experience there were no immune reactions, no neurologic phenomena, no gastrointestinal distress--just the blood sugar consequences.

While this may not be true for all people consuming einkorn, it suggests that primordial einkorn wheat is quite different from modern conventional wheat for most people.

Dr. Joseph Prendergast and l-arginine

7. September 2007 William Davis (21)

In response to a discussion started by Track Your Plaque Member, Rich, on the Member Forum, I tracked down Dr. Joseph Prendergast, who had posted a video on his unique experiences, both personal and professional, with l-arginine.

Dr. Prendergast describes some of this in a brief webcast. Here, I quote Rich:

“This 90-second video by a Palo Alto physician (internal/endocrine, diabetes specialist) will totally blow your mind.

http://enews.endocrinemetabolic.com/2007/08/16-12-years.html

You will see in the link below that he reversed his personal atherosclerotic disease, diagnosed in abdominal aorta at age 37—completely reversed. He's now much older."

http://www.endocrinemetabolic.com/about/press/larginine.pdf

I contacted Dr. Prendergast to find out more.

Dr. Joseph Predergast is founder of the Endocrine Metabolic Medical Center in Palo Alto, California, focused on providing care for people with diabetes. In addition to the website, he provides Blogs and newsletters, though most of his conversation is about diabetes issues. Dr. Predergast’s website is located at http://www.endocrinemetabolic.com.

I asked Dr. Prendergast several questions about his l-arginine experience. His brief answers are below.

1) What dose of l-arginine have you employed in your patients and why this dose?

The dose is 3 - 6 grams as suggested by the Stanford Cardiovascular Research Department Chairman John Cooke. http://med.stanford.edu/profiles/John_Cooke/

2) I gather that you have preference for specific preparations of l-arginine. Can you say why some preparations seem superior to others in your experience?

I started with pharmaceutical l-arginine from the pharmacy. I gradually began to add components that would augment the power of the l-arginine and have gone through 12–15 different products. I have completely reversed my own very severe atherosclerosis discovered at age 37 and there has been less than 0.05% cardiovascular disease in my endocrine practice in almost 17 years. Both my exams were evaluated with CT technology. I am now using ProArgi9 Plus that includes several anti-aging components and will likely never switch. http://www.synergyworldwide.com/synergycorp/home.aspx

3) Are you employing any other unique practices in your patients to reduce cardiovascular events?

Withdrawing as many prescription drugs as possible.

Interesting. Of course, I also advocate l-arginine as a facilitator of atherosclerotic plaque regression, though I am not as ebullient about its use as Dr. Prendergast.

Instead, I see l-arginine as a method that yields forced normalization of “endothelial dysfunction,” the abnormal constriction and other effects that develop when abnormal lipoproteins and unhealthy food by-products are present in the circulation. Endothelial dysfunction is an inevitable accompaniment of plaque.

However, unlike Dr. Predergast’s experience, despite our use of doses higher than he uses, I have never seen plaque regression just using l-arginine alone. Nonetheless, it’s good to hear that others are seeing at least some positive effects.

By the way, we have also had some positive posts on our Forum about the ProArgi9 product he uses.

Dr. Dwight Lundell on omega-3s and CLA

7. September 2007 William Davis (15)

An interview with Dr. Dwight Lundell, cardiac surgeon and author of the new book, "The Cure for Heart Disease."

Dr. Lundell comes to us with a unique pedigree. He is a cardiothoracic surgeon practicing in the Phoenix, Arizona, area. Despite having performed thousands of coronary bypass operations, including numerous "off-pump" procedures earning him a place in the Beating Heart Hall of Fame and a listing in Phoenix Magazine’s Top Doctors for 10 years, more recently Dr. Lundell has turned his attentions away from traditional surgical treatment and towards prevention of heart disease and.

In particular, Dr. Lundell is a vocal advocate for omega-3 fatty acids from fish oil and conjugated linoleic acid, or CLA.

When I heard about Dr. Lundell’s unique perspectives, I asked him if he’d like to tell us a little more about his ideas. Here follows a brief interview with Dr. Lundell.

You’re a vocal advocate of the role of omega-3 fatty acids from fish oil in heart disease prevention. Can you tell us how you use it?

In my book, I recommend 3 g of fish oil daily. This would normally yield about 1000 mg of EPA and DHA depending on the concentration of the supplement. This is approximately the dose that reduced sudden cardiac death by 50%, and all cause death, by 25% in patients with previous heart attack.

In patients with signs of chronic inflammation such as heart disease, obesity, arthritis, metabolic syndrome or depression or in those patients with elevation of CRP, I would recommend higher doses, 2000 to 3000 mg per day of EPA and DHA. The FDA has approved up to 3400 mg for treating patients with severely elevated triglycerides.

I personally take a 2000 mg EPA and DHA per day because I have calcium in my coronary arteries.

Of course, in the Track Your Plaque program we track coronary calcium scores. Do you track any measures of atherosclerosis in your patients to chart progression or regression?

Carotid ultrasound with measurement of IMT [intimal-medial thickness] has been shown to be a good surrogate marker for coronary disease, as has vascular reactivity in the arm. CT scanning with calcium scoring is a direct marker of coronary disease. CT does not differentiate between stable or unstable plaque but there is no good noninvasive way of doing this.

The dramatic value of CT scan calcium scoring is to demonstrate to people that they actually do have coronary disease and to motivate them to make the necessary lifestyle and nutritional changes to reduce it. CT scan with calcium scoring is a direct way to measure the progression or regression of coronary artery disease. If there is a choice between a direct measurement and indirect measurement, always choose the direct method.

Every patient treated with CLA in my clinic, experienced significant reductions in C-reactive protein. These patients were also on a weight-loss program, so I can't prove whether it was the CLA or the weight-loss that improved their inflammatory markers. In the animal model for arteriosclerosis, CLA has a dramatic effect of reducing and preventing plaque. This has not yet been proven in humans.

Normally, when people lose weight 20% or more of the loss is lean body mass (muscle) this lowers the metabolic rate and frustrates further weight-loss. My patient, from teenagers to retirees, lost no lean body mass and continued to have satisfactory weight-loss when CLA was used as part of the plan.

In reading your book, your use of conjugated linoleic acid (CLA) as a principal ingredient struck me. Can you elaborate on why you choose to have your patients take CLA?

My enthusiasm for CLA is based on:

1) Safety?this is of paramount importance. Animal toxicity studies have been done, as well as multiple parameters measured in human studies, both of these are well reviewed recently in the American Journal of Clinical Nutrition (2004:79(suppl)1132s). CLA, a naturally-occurring substance, is not toxic or harmful to animals or humans. The only negative report is by Riserus in Circulation (2002), where he found an elevated c- reactive protein; however, he used a preparation that is not commercially available and not found in nature as a single isomer.

2) Effectiveness?also critically important. A recent meta-analysis [a reanalysis of compiled data] in the American Journal of Clinical Nutrition (2007; 85:1203-1211) demonstrated the effectiveness of CLA in causing loss of body fat in humans. The study also reconfirmed the safety of CLA.

Since we now know that atherosclerosis is an inflammatory disorder, any strategy that reduces low-grade inflammation without significant side effects would seem to be beneficial in the treatment and prevention of atherosclerosis. CLA not only has antioxidant properties, but it modulates inflammatory cascade at multiple points. CLA reduces PGE2 (in much the same way as omega-3) CLA also has been shown to reduce IL-2, tumor necrosis factor-alpha and Cox–2. It reduces platelet deposition and macrophage accumulation in plaques. It also has some beneficial effect in the PPAR [peroxisome proliferator-activated receptors, important for lipid and inflammatory-mediator metabolism] area.

Part of the effect of CLA may be because it reduces fat mass and thus the amount of pro-inflammatory cytokines produced by fat cells.

I reiterate and fully admit that CLA has not been shown to have any effect on atherosclerosis in human beings. However, the results in the standard animal models for atherosclerosis (rabbits, hamsters,APO-E knockout mice) are very dramatic.

From all I know, it appears that the effective dose for weight loss and the animal studies in atherosclerosis would be equal to about 3 g of CLA per day. The anti-inflammatory properties of CLA seem to work better in the presence of adequate blood levels of omega-3.

I’m curious how and why a busy cardiothoracic surgeon would transform his practice so dramatically. Was there a specific event that triggered your change?

The transition from a very busy surgical practice to writing and speaking about the prevention of coronary disease has not been particularly easy, but it has been very interesting. I can't really point to any specific epiphany, it was a general feeling of frustration that we were not making any progress in curing heart disease, which is what I thought I was doing when I began my medical career.

Of course, I enjoyed the technical advances, the dramatic life-saving things that you do and I did on a daily basis. American medicine is spectacularly good at managing crises and spectacularly horrible at preventing those crises.

The lipid hypothesis is old and tired, even the most aggressive statin therapy reduces risk of heart attack by about 30% in a relatively small subset of people. It's interesting that we're now looking at statins as an anti-inflammatory agent.

Thanks, Dr. Lundell. We look forward to future conversations as your experience with CLA and heart disease prevention and reversal develops!

Note: We are planning a full Special Report on CLA for the Track Your Plaque website in future.

High-tech heart attack proofing

5. September 2007 William Davis (7)

I was reminiscing the other day about what I was taught about heart disease in medical school some 20 years ago.

In the 1980s, the world was still (and remains) fascinated with this (then) novel "solution" to heart disease called coronary bypass surgery. As medical students, we all fought for a chance to watch a bypass operation being performed. And there was lots of opportunity. I was a medical student at St. Louis University School of Medicine, a center that boasted of a busy thoracic surgery service, performing up to 10 bypass operations every day.

Back then, coronary angioplasty was just a twinkle in Andreas Gruentzig's eye, still contemplating whether it was possible to put an inflatable device in the blockages of coronary arteries to re-establish blood flow. Risk detection for heart disease consisted of EKGs, screening for symptoms, detection of heart failure, and tests that are long forgotten in the dust bin of medical curiosities, tests like systolic-time intervals, phonocardiography (using amplified sound to detect abnormal heart sounds), and detailed physical examination. Treatment for heart attack involved nitroglycerin and extended bedrest. Bypass surgery would come after you recovered.

In other words, NONE of the tools we now use in the Track Your Plaque program for heart disease control and reversal were available just twenty years ago. There was no lipoprotein testing, no CT heart scans. Nobody recognized the power of omega-3 fatty acids (although epidemiologic observations were just beginning to suggest that eating fish might be the source of reduced risk for heart attack and cardiovascular death). Vitamin D? Why, that's in your milk so your babies don't get rickets.

So much of what we do today was not available then, nor were they even in the crystal ball of forward-looking people. I certainly had no idea whatsoever that I'd be talking and obsessing today about reversal of heart disease based on what I saw and learned back then.

Things have certainly come a long way and all for the better. The problem is that much of the world is stuck in 1985 and haven't yet heard that coronary disease is a manageable and reversible process. They've been sidetracked by the fiction propagated by the likes of Dr. Dean Ornish, the nonsense of low-fat diets aided and abetted by the food manufacturing industry and the USDA, the extravagant claims of some practitioners and the supplement industry. They haven't yet stumbled on the real-life experiences that are chronicled here in this Blog and the accompanying Track Your Plaque website.

Our program has been criticized for being too "high-tech," involving too many sophisticated measures like small LDL, lipoprotein(a) treatment, vitamin D blood levels. But when you see a woman reduce her heart scan score 63%, or a school principal's score plummet 51%, then that's reward in itself.

It's all about plaque

5. September 2007 William Davis (0)

Just to keep my finger on the pulse of what is being said in the world of heart disease by the media, I subscribe to many publications.

Conversations abound about cholesterol, low-fat diets, now low-carb diets, not smoking, inflammation, etc. No doubt, these all have some importance in the conversation.

But the great majority of discussions fail to identify the one truly crucial factor to identify and track: coronary atherosclerotic plaque.

Sugar for breakfast

2. September 2007 William Davis (17)

We were reviewing Stuart's diet because of his persistent small LDL, low HDL, modestly elevated triglycerides, and blood sugar of 107 mg/dl.

"I've changed my diet, doc. No kidding. We never fry our foods. No butter, no goodies. I don't know what else I can possibly do."

"Okay. Let's review your diet. What did you have for breakfast?"

"Orange juice, a big glass. Gotta get my potassium. Then cereal like Cheerios or Shredded Wheat, sometimes Kashi or Raisin Bran, always in skim milk. Gotta have my one slice of toast, no butter. I'll put some fruit preserves on it. You know, real fruit. Only whole wheat bread, never white. On Sundays, we always go out for pancakes, but now we order only whole wheat."

Many of us have gotten into a peculiar habit: Having what amounts to pure sugar for breakfast. Perhaps there's a little fiber thrown in with it, but many people indulge in breakfasts that are sugar and plenty of it. That's precisely what Stuart is doing: A breakfast that, while it doesn't contain a huge amount of sugar outside of the orange juice, is promptly converted to sugar. If we were to check his blood sugar just after his standard breakfast, it would rise substantially.

This pattern has become deeply ingrained into the American psyche. Some people will act like I've suggested we overthrow the government when I suggest that breakfast cereals need to be eliminated from their lives. We all share memories of Tony the Tiger, the leprechaun on Lucky Charms ("They're magically delicious!), reading the brightly colored boxes often including games and prizes. Breakfast cereals seem as American as apple pie. But the wheat and corn content ensures a big rise in blood sugar, the sort that create small LDL, low HDL, etc.--all the patterns Stuart is showing--and make us fat.

Orange juice? Too much sugar all at once. Get your potassium from whole vegetables and fruits, not from orange juice. (Bananas are another problem source of potassium for similar reasons despite being a whole fruit.)

Toast? Any diabetic who monitors their blood sugar after meals will tell you: Even one slice of bread, ANY bread, skyrockets blood sugar. Add the fruit preserves made with sugar syrup and it's doubly worse.

Pancakes? Even if made with plenty of fiber, blood sugars go absolutely berserk after a meal like this, especially if maple syrup is added.

In other words, the seemingly healthy breakfast Stuart eats guarantees that he fails to control all his patterns that contribute to his coronary plaque growth.

After I pointed out Stuart's dietary faux pas, he asked, "Then what the heck can I eat?"

"There's actually lots of good choices: Eggs (preferably free-range, if available, or the 'omega-3' enriched) or Egg Beaters; oat products, but true oat products like slow-cooked oatmeal, or the best of all, oat bran, used as a hot cereal; ground flaxseed as a hot cereal with added fruit, berries, nuts; a handful of raw almonds, walnuts, pecans; some cheese, preferably traditional fermented cheese and not processed; low-fat cottage cheese; low-fat yogurt that you flavor yourself with berries and nuts; raw seeds like sunflower and pumpkin.

"Try and save some of your dinner foods for breakfast. For instance, save some green peppers and onions from your salad and put it in your scrambled eggs along with some olive oil. Save some of the chicken and add it to your breakfast. Save some of the cooked vegetables and have them as they are. You'll be surprised how filling dinner foods can be when eaten for breakfast."

It's not that tough. But Stuart and many other people need to break the hold that the food manufacturers have created. If you're hoping to seize hold of your heart scan score, get rid of the sugar foods in your morning, even the ones cleverly disguised as healthy.

The Low-Carb Man

31. August 2007 William Davis (4)

If ever there was an enthusiastic disciple of deceased Dr. Robert Atkins of Atkins' Diet fame, it's Mr. Jimmy Moore.

Jimmy tells the story of how he was transformed by the Atkins' approach, losing 180 lbs in the course of one year. He continues to develop this conversation, in many ways elaborating on the conversation in more sophisticated ways than even Atkins did in his lifetime.

Though we've agreed to disagree on some points of nutrition, Jimmy and I had a recent discussion about heart disease, the mis-guided ways of conventional cardiac care,and the evils of processed carbohydrates. We do differ on the role of saturated fat in heart disease and health, but beyond that difference I was impressed (reading his Blog and listening to his many webcasts) with his level of understanding of the issues. Jimmy is not some over-enthusiastic dieter. He has a grasp of the issues that exceeds that of 99% of my colleagues.

If you are interested in reading our discussion or just perusing a really fun, informative Blog/website, go to LivinLaVidaLowCarb.com. The interview is posted at:

See Jimmy Moore's before and after pictures at http://livinlavidalocarb.blogspot.com/2005/07/my-before-pictures.html. He's quite an entertaining read.

Why average cholesterol values can be so bad

30. August 2007 William Davis (23)

Jack had been told again and again that there was absolutely nothing wrong with his cholesterol panel. His numbers:

Total cholesterol 198 mg/dl

LDL cholesterol 119 mg/dl--actually below the national average (131 mg/dl).

HDL 48 mg/dl--actually above the average HDL for a male (42 mg/dl).

Triglycerides 153 ng/dl--right at the average.

So his primary care physician was totally stumped when Jack's heart scan revealed a score of 410.

Lipoprotein analysis (NMR) told an entirely different story:

LDL particle number 1880 nmol/l (take off the last digit to generate an approximate real LDL, i.e., 188 mg/dl).

Small LDL 95% of all LDL particles, a very severe pattern.

A severe excess of intermediate-density lipoprotein (218 nmol/l), suggesting that dietary fats are not cleared for 24 hours or so after a meal.

And those were just the major points. In other words, where conventional cholesterol values, or lipids, failed miserably, lipoprotein analysis can shine. The causes for Jack's high heart scan score become immediately apparent, even obvious. Jack's abnormalities are relatively easy to correct--but you have to know if they're present before they can be corrected. A shotgun statin drug approach could only hope to correct a portion of this pattern, but would unquestionably fail to fully correct the pattern.

As I've said before, standard cholesterol testing is a fool's game. You can squeeze a little bit of information out of them, but there's so much more information that can be easily obtained through lipoprotein testing like Jack had.

Cholesterol trumps heart scan?

28. August 2007 William Davis (4)

Lela's heart scan score: 449--very high for a 49-year old, peri-menopausal woman. Her score placed her flat in the 99th percentile, or the worst 1% of women her age.

Lela first consulted her primary care physician. Her doctor looked at the result puzzled. "Now wait a minute. Your cholesterol numbers have been great." After a pause, her doctor (a woman) declared the heart scan wrong. "Tests aren't perfect. The heart scan is simply wrong. I'm going to believe the cholesterol numbers and there's no way you have heart disease."

Is that right? Can cholesterol numbers trump your heart scan score? Can the heart scan simply be wrong?

The answer is simple: NO.

The heart scan is not wrong. The heart scan is right. What is wrong with this picture is that standard cholesterol testing commonly and frequently fails to identify people at risk for heart disease.

What if this woman smoked? That wouldn't be revealed in her cholesterol panel. Or had high blood pressure, increased inflammatory responses like C-reactive protein, had increased small LDL or lipoprotein(a), was severely deficient in vitamin D? None of that would be revealed by cholesterol numbers.

So, no, the heart scan is not wrong. The cholesterol numbers are not wrong. The doctor's interpretation of the data is wrong.

Please do not allow false reassurances offered by those who do not understand the technology steer you wrong.

This woman proved to have an entire panel of hidden causes of her coronary plaque uncovered. No surprise.

Boycott LabCorp

27. August 2007 William Davis (13)

Track Your Plaque Members have been following this conversation on the Track Your Plaque Forum.

A good number of people have had their blood drawn for NMR lipoprotein analysis through laboratories operated by the Laboratory Corporation of American, or LabCorp. When the results were returned, the very important page 2 of the report was withheld. Many of us have communicated with the company, only to be given some corporate-speak about internal policy.

I have personally expressed my dissatisfaction, my outrage, at this silly policy. Why would laboratory results that you or your insurance paid for be denied to you? It is my understanding that, on request, you are legally entitled to the information. The page 2 information is provided by the laboratory (Liposcience, Inc.) that actually performs the testing. LabCorp does nothing more than draw the blood, prepare the specimen, then convey and dilute the results that Liposcience reports to them.

My personal suspicion is that the LabCorp people do this to 1) make the results appear that they actually performed the tests and not farmed to an outside laboratory (Liposcience), and 2) not further confuse and befuddle the bungling primary care physician who barely understands cholesterol issues to begin with. "LDL, HDL, triglycerides . . . What now--a bunch of new information, bars even!?

To me, this LabCorp policy is criminal. In fact, I wonder if this has the substance to justify a class action lawsuit against LabCorp. I believe that we can easily make a case that crucial health information is being systematically denied to people.

If this has affected you, or if you share in the frustration of many people who have had watered down lipoprotein results provided, write to:

Ken Younts, VP of Sales at LabCorp. Yountsk@labcorp.com

Or, write to:

Tom MacMahon
Chairman of the Board

David P. King
President and Chief Executive Officer

Laboratory Corporation of America Holdings
358 South Main Street
Burlington, NC 27215

Thanks to the Track Your Plaque Members who have already participated in this campaign and written to the LabCorp people. And thanks to our Members who uncovered the contact information.

Until then, please BOYCOTT LABCORP LABORATORIES. Please do not use LabCorp Laboratories if you can avoid it. Simply ask the laboratory staff who operates the lab and they should tell you. It is your right to know.

Useless low-fat diets

24. August 2007 William Davis (1)

If you would like to read an ironic testimonial to the futility of conventional low-fat diets, read:

Cutting Cholesterol, an Uphill Battle on the New York Times website at http://www.nytimes.com/2007/08/21/health/21brod.html?_r=2&adxnnl=1&oref=slogin&ref=health&adxnnlx=1187928650-f0mfyzGTFdsLmtInHcGPUw

In this story, author and columnist Jane Brody recounts her struggles with her cholesterol levels. She describes how she followed an increasingly strict low-saturated fat diet, hoping to reduce LDL cholesterol. But she saw the opposite occur: LDL climbed from an initial 134 to 171, a level that caused her doctor to prescribe a statin drug.

Yet she states that "About 85 percent of the cholesterol in your blood is made in your body. The remaining 15 percent comes from food. But by reducing dietary sources of saturated fats and cholesterol and increasing consumption of cholesterol-fighting foods and drink, you can usually lower the amount of harmful cholesterol in your blood."

Had Ms. Brody and her doctor been just a bit better informed and performed lipoprotein analysis instead, they would have seen some obvious phenomena:

--All the increase in LDL was in the fraction of small particles, the sort highly likely to cause heart attack.

--The conventional LDL that she quotes is a calculated value that miserably misrepresents the real LDL when actually measured. Her calculated LDL of 171 mg/dl, in fact, was probably more like 220 to 250 mg/dl--much higher than they think.

Of course, Ms. Brody turns to her conventionally-thinking physician who then predictably prescribes a statin drug.

Ms. Brody's well-articulated story achieves the ironic, unintended result of proving the idiocy of the conventional low-fat diet. The low-fat diet, as currently practiced by most people, raises LDL cholesterol and escalates risk for heart disease. In fact, Ms. Brody probably increased her risk far more than suggested by a 30 mg increase in LDL.

One of my favorite blogs, the Fanatic Cook, has a tremendously insightful post on Ms. Brody's misadventures.

If all she did was eliminate all wheat flour containing products and reduce the overall glycemic index of her diet, she would witness an enormous drop in LDL cholesterol, both calculated and measured.

I hope that Ms. Brody survives her diet mistakes and her doctor's ignorance.

Roger's near-miss CT angiogram experience

27. June 2009 William Davis (13)

Heart Scan Blog reader, Roger, described his near-miss experience with CT coronary angiograms.

Hoping to obtain just a simple CT heart scan, he was bullied to get a CT coronary angiogram instead. Roger held strong and just asked for the test that we all should be having, a CT heart scan.

I posted yesterday that I was about to have my first CT heart scan...well, it was an interesting experience for reasons I coudn't possibly have anticipated. Dr. Davis has commented in the past on the confusion in the media about the difference between a CT calcium score scan, and a CT angiography, the latter requiring a far higher dose of radiation. I assumed this was a source of confusion only among patients and lay folks, but, lo and behold, I discovered today that doctors--or at least their helpers--can be just as confused.

Here's my story:

After checking in, I asked the receptionist to see if she had any information on whether my medical insurance was covering the scan. She called someone, and I heard her say over the phone, "He's here for a CT angiogram." At that point my ears perked up. I explained I wasn't here for a CT angiogram, only a regular CT scan. "Well, do you want to call your doctor and talk about this?" she asked. No, I said, I would like to ask one of their folks to verify exactly what test my doctor had ordered. As luck would have it, the technician was walking by at that point. "Is this a CT angiogram?" the receptionist asked. "No, it's just a CT calcium score scan" was the reply. But apparently the technician had been unclear herself, and had called my doctor just to verify. In other words, the "default" procedure they were accustomed to doing at this august Houston vascular clinic was a CT angiogram.

In fact, my appointment was even listed on their calendar as a "CT angiogram." For all I know, my insurance will be billed for the same. Later, during the procedure, the technician acted surprised I wasn't doing the "full test." I explained I had minimal risk factors (actually only one, an HDL of 34 a couple of years ago, which has since been raised to 50 partly as a result of taking advice from this site), but that my doctor was progressive (he is an MD for the Houston Astros) and thought it was a good idea since there is heart disease in my immediate family. My doctor did indeed prescribe only a CT calcium score scan, but it seems to have been an order that this clinic, at least, wasn't all that used to seeing.

So, I guess the message is: we have a lot of educating to do. Had I not been a faithful reader of these pages, I certainly wouldn't have known what kind of test I was about to get, or what questions to ask!

As for the heart scan itself, a piece of cake. If you can hold your breath, you can take this test. Just be sure it is the right one!

Why the "push" towards CT coronary angiograms and not "just" a CT heart scan? Well, I know it's shocking but it's . . . money!

CT coronary angiograms yield around $1800-$4000 per test. CT heart scans yield somewhere around $200. Though the scan center support staff might not care too much about the money themselves, their administrators likely make the cost distinctions clear to them.

Another reason: Most scan center staff, ironically, don't understand what a heart scan means, nor do they understand how it might serve to launch a program of prevention. They do understand that severe blockage by CT angiogram "needs" to be stented or bypassed. So they push patients towards things they understand.

Nobody makes money from CT heart scans, just as nobody makes money from a mammogram. Heart scans also don't lead to heroic, "lifesaving" procedures. They just lead to this sleepy, unexciting, inexpensive thing called prevention.

The Myth of Prevention: Letter to the Wall Street Journal

25. June 2009 William Davis (20)

The June 20-21, 2009 Wall Street Journal Weekend Journal featured a provocative front page article written by physician, Dr. Abraham Verghese:

The Myth of Prevention

While eloquently written, I took issue with a few crucial points. Here is the letter I sent to the Editor at Wall Street Journal:

Dear Wall Street Journal Editor,

Re: Dr. Abraham Verghese’s article, The Myth of Prevention in the June 20-21, 2009 Weekend Journal.

I believe a more suitable title for Dr. Verghese’s article would be: “The Myth of What Passes as Prevention.”

As a practicing cardiologist, I, too, have witnessed firsthand the systemic “corruption” described by Dr. Verghese, the doing things “to” people rather than “for” them. Heart care, in particular, is rife with this form of profit-driven health delivery.

There is a fundamental flaw in Dr. Verghese’s otherwise admirable analysis: He assumes that what is called “prevention” in mainstream medicine is truly preventive.

Dr. Verghese makes issue of the apparent minor differences between preventing a condition and just allowing a condition to run its course. Prostate cancer screening is one example: Men subjected to repeated screenings have little length-of-life advantage over men who just allow their prostate to suffer the expected course of disease.

What if, instead, “prevention” as practiced today is nothing more than a solution that has been adopted in mainstream practice to suit yet another doing “to” strategy than doing “for”? In the prostate cancer example, PSA and prostate exam screenings often serve as little more than a means of harvesting procedures for the local urologist.

That’s not prevention. It is a prototypical example of “prevention” being subverted into the cause of revenue-generating procedures.

I submit that Dr. Verghese has fallen victim to the very same system he criticizes. His views have unwittingly been corrupted by the corrupt profit-driven system he describes.

What if, instead, prevention were just that: prevention or elimination of the condition. What if “prevention” of prostate cancer eliminated prostate cancer? What if heart disease “prevention” prevented all heart disease? What if this all proceeded without regard for profit or revenue-generating procedures, but just on results?

Dr. Verghese specifically targets heart scans or coronary calcium scoring, a test he likens to “miracle glow-in-the-dark minnow lures,” calling them “moneymakers.” Yes, when subverted into a corrupt algorithm of stress test, heart catheterization, stent, or bypass, heart scans are indeed a test used wrongly to “prevent” heart disease.

But what if the risk insights provided by heart scans prompt the start of a benign yet effective “prevention” program that inexpensively, safely, and assuredly prevents--in the true sense of the word--or eliminates heart disease? Then I believe the differences in mortality, quality of life, and costs would be substantial. Such strategies exist, yet do not necessarily include prescription drugs and certainly do not include the aftermath of heart catheterization and bypass surgery. Yet such programs fail to seize the limelight of media attention with no new high-tech lifesaving headline nor a big marketing budget to broadcast its message.

The problem in medicine is not prevention and its failure to yield cost- and life-saving results. It is the pervasively profit-driven mindset that keeps true preventive strategies from entering mainstream conversation. It is a repeat of Dr. Ignaz Semmelweis’ late 19th-century pleads for physicians to wash their hands before delivering babies to reduce puerperal sepsis, ignominious advice that earned him life and death in an asylum. We are essentially continuing to deliver children with unwashed hands because there is no revenue-generating procedure to clean them.

No, Dr. Verghese, the economic and medical failings of preventive strategies are not at fault. The failure of the medical system, in which everyone is bent on seizing a piece of the financial action for himself, has resulted in the failure to support the propagation of true preventive strategies that could genuinely save money and lives.

President Obama’s goal of cultivating preventive practices in medicine can work, but only if the profit-motive for “prevention” does not serve as the primary determinant of practice. Results-driven practices that are applied without regard to profit have the potential to yield the sorts of cost-saving and life-saving results that can reduce healthcare costs.

A victory for SHAPE, CT heart scans, and doing what is RIGHT

24. June 2009 William Davis (7)

The efforts of Texas House of Representatives Rep. Rene Oliveira and the SHAPE Guidelines committee have paid off: The Texas legislature passed a bill that requires health insurers to cover CT heart scans.

(NOTE: Don't make the same mistake that the media often makes and confuse CT heart scans with CT coronary angiography: two different tests, two different results, two different levels of radiation exposure. The difference is discussed here.)

Track Your Plaque previously reported the release of the SHAPE Guidelines, an ambitious effort to open CT heart scanning to people who would benefit from a simple screening test for coronary disease. Rep. Rene Oliveira initially introduced the bill in 2006, after having a heart scan uncovered extensive coronary plaque that resulted in coronary bypass surgery.

The bill requires that health-benefit providers cover the cost of CT heart scans (and carotid ultrasound) in men between the ages of 45-76, women 55-76, as well as anyone with diabetes or at "intermediate-risk" or higher for coronary disease by Framingham risk score.

The usual panel of cardiology knuckleheads stepped to the media podium, expressing their incredulity that something as "unvalidated" as heart scans could gain the backing of legislative mandate. Heartwire carried this comment:

"Contacted by heartwire, Dr Amit Khera (University of Texas Southwestern Medical Center, Dallas) confirmed there are still no comprehensive, adequately powered studies showing that these screening tests lead to better outcomes. In a phone interview, Khera said he has major concerns about how physicians will use these tests, particularly primary-care physicians. "I gave a talk last week to primary-care doctors, and there were probably 250 people in the room, and when I asked how many people had ordered a calcium scan, just one person raised a hand. . . . Most people don't even know what to do with the Framingham risk score, so they're going to follow an algorithm that they don't know how to follow to order a test result that they don't know what to do with."

It's the same criticisms hurled at heart scans over the years despite literally thousands of studies validating their application.

Studies have conclusively shown that:

--Coronary calcium scores generated by a CT heart scan outperform any other risk measure for coronary disease, including LDL cholesterol, c-reactive protein, total cholesterol, HDL cholesterol, blood pressure.
--Coronary calcium scores yield a graded, trackable index of coronary risk. Scores that increase correlate with increased risk of cardiovascular events; scores that remain unchanged correlate with much reduced risk.
--A coronary calcium score of zero--no detectable calcium--correlates with extremely low 5-year risk for cardiovascular events.
--Coronary calcium scores correlate with other measures of coronary disease. Heart scans correlate with coronary angiography, quantitative coronary angiography, carotid ultrasound (intimal-medial thickness and plaque severity), ankle-brachial index, and stress tests, including radionuclide (nuclear) perfusion imaging.

The reluctance of my colleagues to embrace heart scans stems from two issues, for the most part:

1) No study has yet been performed showing that knowing what the score is vs. not knowing what the score is changes prognosis. That's true. But it is also true of the great majority of practices in medicine. While many wrongs don't make a right, the miserable and widespread failure of other coronary risk measures, like LDL cholesterol or c-reactive protein, to readily and reliably detect hidden coronary disease creates a gaping void for improved efforts at early detection. If your LDL cholesterol is 140 mg/dl, do you or don't you have coronary disease? If your doctor's response is "Just take a statin drug anyway" you've been done a great disservice. (If and when this sort of study gets done, its huge cost--outcome studies have to be large and last many years--it will likely be a statin study. It is unlikely it will include such Track Your Plaque strategies that help reduce heart scan scores, like vitamin D and correction of small LDL particles.)

2) Fears over overuse of hospital procedures triggered by heart scans. This is a legitimate concern--if the information provided by a heart scan is misused. Heart scans should never--NEVER--lead directly to heart catheterization, stents, bypass surgery. Heart scans do not change the indications for performing revascularization (angioplasty, stents, bypass). Just because 20% of my cardiology colleagues are more concerned with profit rather than patient welfare does not invalidate the value of the test. Just because the mechanic at the local garage gouged you by replacing a carburetor for $800 when all you need was a new spark plug does not mean that we should outlaw all auto mechanics. Abuse is the fault of the abuser, not of the tool used to exercise the abuse.

All in all, while I am not a fan of legislating behavior in healthcare, the blatant and extreme ignorance of this simple tool for uncovering hidden heart disease makes the Texas action a huge success for heart disease prevention. I hope that this success will raise awareness, not just in Texas, but in other states and cities in which similar systemic neglect is the rule.

Remember: CT heart scans are tools for prevention, not to uncover "need" for procedures. They serve as a starting point to decide whether or not an intensive program of prevention is in order, and I don't mean statin vs. no statin.

Though not a multi-million dollar statin drug study, I have NEVER seen a heart attack or "need" for procedure in any person who has stopped progression or reduced their heart scan score. A small cohort from my practice was reported:

Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.

Davis W, Rockway S, Kwasny M.

The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides /=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.

Sleep: A to Zzzzzzzzzz

23. June 2009 William Davis (5)

Take a look at the results from the Heart Scan Blog's most recent reader poll (399 respondents):

How many hours do you sleep per night (on average)?

9 or more hours per night
15 (3.7%)

8-9 hours per night
72 (18%)

7-8 hours per night
152 (38.1%)

6-7 hours per night
111 (27.8%)

5-6 hours per night
38 (9.5%)

Less than 5 hours per night
11 (2.8%)

Like many issues in health, too much or too little of a good thing can present undesirable consequences.

Too much sleep: While psychologists and sleep researchers advise us that at least 9 hours are required to fully eliminate sleep "debt" and achieve optimal vigilance and mental performance, epidemiologic studies have shown increased mortality with this quantity of sleep.

Too little sleep: Getting less than 7 hours habituallly increases blood sugar, appetite, inflammatory measures, and encourages weight gain. Mortality is also increased, just as with sleeping too much. It is also associated with increased likelihood of a positive heart scan score.

7-8 hours per night from a health viewpoint is that Goldlilocks "just right" value: just enough to not erode mental performance substantially, but not so little that inflammatory, insulin-disrupting, and appetite-increasing effects develop.

Of our 399 respondents in the poll, 56.1% (38% + 18%) slept what appears to be an optimal amount for health. While only 3.7% slept too much (9 hours or more), the remaining 40.1% slept too little.

Our informal poll confirms what most of us observe in everyday life: The majority of people shortchange sleep in order to meet the demands of their high-pressure, squeeze-as-much-as-possible-into-every-day lives. But not paying off your sleep "debt" is like not paying the mortgage for a couple of months. You wouldn't expect your friendly neighborhood bank to say, "Oh, you forgot to pay your mortgage? Forget about it. Just pay next month's." Sure, fat chance. But if you don't pay off your sleep "debt," you will pay it back with health.

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

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.

Increased blood calcium and vitamin D

21. June 2010 William Davis (50)

Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

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

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

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

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

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

Heart health consultation with Dr. Joe D. Goldstrich

20. June 2010 William Davis (3)

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

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

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

Wheat aftermath

16. June 2010 William Davis (18)

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

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

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

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

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

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

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

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

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

In search of wheat: Einkorn and blood sugar

14. June 2010 William Davis (32)

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

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

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

Here's what happened:

Einkorn wheat bread:

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

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

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

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

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

In search of wheat: We bake einkorn bread

12. June 2010 William Davis (6)

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

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

Here's what we did:

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

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

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

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

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

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

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

The einkorn dough also distinctly smelled like peanut butter.

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

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

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

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

Margaret Pfeiffer's book is available on Amazon:

Ezekiel said what?

10. June 2010 William Davis (24)

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

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

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

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

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

Are you sure about that?

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

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

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

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

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

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

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

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

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

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

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

Low-carb gynecologist

6. June 2010 William Davis (36)

I met infertility specialist, Dr. Michael Fox, on Jimmy Moore's low-carb cruise just this past March.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Track Your Plaque reduces healthcare costs 35%

29. May 2010 William Davis (12)

Allow me to wear my Track Your Plaque hat for this post.

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

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

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

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

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

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

In search of wheat

26. May 2010 William Davis (43)

Many people ask: "How can wheat be bad if it's in the Bible?"

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

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

So how can wheat be bad?

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

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

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

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

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

Super-carbohydrate

22. May 2010 William Davis (18)

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

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

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

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

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

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

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