Why does wheat cause arthritis?

13. November 2010 William Davis (48)
Wheat causes arthritis.

Before you say "What the hell is he saying now?", let me connect the dots on how this ubiquitous dietary ingredient accelerates the path to arthritis in its many forms.

1) Wheat causes glycation--Glycation is glucose-modification of proteins in the body that occurs when blood glucose exceeds 100 mg/dl. Cartilage cells are especially susceptible to glycation. The cartilage cells you had at age 18 are the very same cartilage cells you have at age 60, since they lack the ability to reproduce and repair themselves. Proteins in cartilage are highly susceptible to glycation, which makes them stiff and brittle. Stiff, brittle cartilage loses its soft, elastic, lubricating function. Damaged cartilage cells don't regenerate nor produce more protective proteins. This allows destruction of cartilage tissue, inflammation, and, eventually, bone-on-bone arthritis.

Because wheat, even whole wheat, sends blood sugar higher than almost all other foods, from table sugar to Snickers bars, glycation occurs after each and every slice of toast, every whole wheat bagel, every pita wrap.

2) Wheat is acidifying--Humans are meant to consume a diet that is net alkaline. While hunter-gatherers who consume meat along with plentiful vegetables and fruits live a net alkaline diet (urine pH 7 to 9), modern humans who consume insufficient vegetables and too much grain (of which more than 90% is usually wheat) shift the body towards net acid (urine pH 5 to 7). Wheat is The Great Disrupter, upsetting the normal pH balance that causes loss of calcium from bones, resulting in decalcification, weakness, arthritis and osteoporotic fractures.

3) Wheat causes visceral fat--The extravagant glucose-insulin surges triggered by wheat leads to accumulation of visceral fat: wheat belly.

Visceral fat not only releases inflammatory mediators like tumor necrosis factor and various interleukins, but is also itself inflamed. The inflammatory hotbed of the wheat belly leads to inflammation of joint tissues. This is why overweight and obese wheat-consuming people have more arthritis than would be explained by the burden of excess weight: inflammation makes it worse. Conversely, weight loss leads to greater relief from arthritis pain and inflammation than would be explained by just lightening the physical load.

We need a name for this wheat effect. How about "bagel bones"?

Why do morphine-blocking drugs make you lose weight?

10. November 2010 William Davis (24)
Naloxone (IV) and naltrexone (oral) are drugs that block the action of morphine.

If you were an inner city heroine addict and got knifed during a drug deal, you'd be dragged into the local emergency room. You're high, irrational, and combative. The ER staff restrain you, inject you with naloxone and you are instantly not high. Or, if you overdosed on morphine and stopped breathing, an injection of naloxone would reverse the effect immediately, making you sit bolt upright and wondering what the heck was going on.

So what do morphine-blocking drugs have to do with weight loss?

An odd series of clinical studies conducted over the past 40 years has demonstrated that foods can have opiate-like properties. Opiate blockers, like naloxone, can thereby block appetite. One such study demonstrated 28% reduction in caloric intake after naloxone administration. But opiate blocking drugs don't block desire for all foods, just some.

What food is known to be broken down into opiate-like polypeptides?

Wheat. On digestion in the gastrointestinal tract, wheat gluten is broken down into a collection of polypeptides that are released into the bloodstream. These gluten-derived polypeptides are able to cross the blood-brain barrier and enter the brain. Their binding to brain cells can be blocked by naloxone or naltrexone administration. These polypeptides have been named exorphins, since they exert morphine-like activity on the brain. While you may not be "high," many people experience a subtle reward, a low-grade pleasure or euphoria.

For the same reasons, 30% of people who stop consuming wheat experience withdrawal, i.e., sadness, mental fog, and fatigue.

Wouldn't you know that the pharmaceutical industry would eventually catch on? Drug company startup, Orexigen, will be making FDA application for its drug, Contrave, a combination of naltrexone and the antidepressant, buproprion. It is billed as a blocker of the "mesolimbic reward system" that enhances weight loss.

Step back a moment and think about this: We are urged by the USDA and other "official" sources of nutritional advice to eat more "healthy whole grains." Such advice creates a nation of obese Americans, many the unwitting victims of the new generation of exorphin-generating, high-yield dwarf mutant wheat. A desperate, obese public now turns to the drug industry to provide drugs that can turn off the addictive behavior of the USDA-endorsed food.

There is no question that wheat has addictive properties. You will soon be able to take a drug to block its effects. That way, the food industry profits, the drug industry profits, and you pay for it all.

Heart scan tomfoolery 2

9. November 2010 William Davis (2)
In the last Heart Scan Blog post, I discussed the significance of the apparent discrepancy between Steve's heart scan score and volume score. This post addresses his second question, also a FAQ about heart scan scores.

Steve noted that his second scan compared to his first showed:

- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

So there are apparent divergences in behavior in the left main that increased and both LAD (left anterior descending) and LCX (left circumflex) that decreased.

The explanation is simple: When heart scans are "scored," they are viewed in horizontal "slices." When the heart is viewed as horizontal slices, the LAD and LCX originate from the common left main stem. In other words, it's like a tree with the left mainsteam representing the trunk, the LAD and LCX representing two main branches.

Plaque can form, obviously, in all three arteries, but it can do so by starting in the left main, for instance, and extending into either the LAD or LCX, or both. The left main plaque can therefore bridge any 2 or all 3 arteries.

When the plaque is "scored" by taking the computer mouse and circling the calcified plaque in question (to allow the computer program to generate the calcium score and volume score of that particular plaque), the plaque that may extend from left main into the LAD and/or LCX might be labeled "left main," or it might be labeled "LAD" or "LCX." There is no reliable way to "dissect" apart the plaque into the three arteries, since the plaque is coalescent and continuous. So the scoring technologist or physician simply arbitrarily declares the artery "LAD," for instance.

The problem comes when two different interpretation methods are used: Perhaps it's a new technologist or physician, or there was no attention paid to how the previous scan was read. One reader calls it "left main" and the next calls it "LCX."

So the apparent discrepancy has to do with flaws in the methods of segregating plaque location, as well as inattention to scoring techniques. The total score, however, remains unaffected.

Nonetheless, Steve has enjoyed a modest reduction in the score of the left main/LAD/LCX from his original 140.8 down to a second left main/LAD/LCX score of 126.9.

The right coronary artery (RCA), however, is not subject to this difficulty and Steve score shows a modest increase in score. (Why the divergent behavior between left main/LAD/LCX and RCA? There is no clear explanation for this, unfortunately.)

All in all, the news for Steve is good: He achieved these results on his own using nutritional techniques. Because he, in all practicality, stopped the progression of his heart scan score and avoided the "natural" rate of increase of 30% per year, all he needs to do is "tweak" his program a bit to achieve reversal, i.e., reduction of score.


Here's an image from another previous Heart Scan Blog post (about the relationship of osteoporosis and coronary disease) that shows such a plaque that starts in the left mainstem yet extends into both the LAD and LCX:

Heart scan tomfoolery

4. November 2010 William Davis (12)
Heart Scan Blog reader, Steve, sent these interesting questions about his heart scan experience. (I sometimes forget that this blog is called "The Heart Scan Blog" and was originally--several years ago--meant to discuss heart scans. It has evolved to become a much broader conversation.)

The answers are a bit lengthy, so I'll tackle Steve's questions in two parts, the second in another blog post.

Dr. Davis,

I had a heart scan last year. The score was 96. While not a horrible score, it
was a wake up call, and I changed my lifestyle.

I had another scan this year and the heart scan score went up to 105, but the
volume score went down from 141 to 136.

The report I received said this:

'The calcium volume score is less in the current study as compared with the
original or reference study. This is an excellent coronary result and indicates
that there has been a net decrease in coronary plaque burden. The current
prevention program is very effective and should be continued.'

This is all well and good, but I have two questions:

1. Am I really going in the right direction even though the heart scan score
went up 9%?

2. Here are results that make no sense to me:
- Left Main volume went up from 22.4 to 35.6
- LAD went down from 95.2 to 91.3
- LCX volume went down from 23.2 to 0
- RCA volume went up from 0 to 9.3

Why would there be so much variation from year to year, and why would the plaque
move from site to site?

Steve

Questions like Steve's come up with some frequency, so I thought it would be worthwhile to discuss in a blog post.

First of all, the conventional heart scan score, or "calcium score" or "Agatston score" (after Dr. Arthur Agatston, developer of the simple algorithm for calcium scoring, as well as South Beach Diet fame), is the product of the area of the plaque in a single CT "slice" image
multiplied by a density coefficient, i.e., a number ranging from 1 to 4 that grades the x-ray density of the plaque. (1 is least dense; 4 is most dense.) A density coefficient of 1 therefore signifies some calcium within plaque, with higher density coefficients signifying increasing calcium content and density. Incidentally, "soft" plaque, i.e., non-calcified, would fall in the less than 1 range, even the negative range (fatty tissue within plaque).

The volume, or "volumetric," score is the brainchild of Drs. Paulo Raggi and Traci Callister, who expressed concern that, if we cause plaque to shrink in volume, the density coefficient used to calculate the calcium score would increase (since they believed that calcium could not be reduced, contrary to our Track Your Plaque experience, thereby leading to misleading results. They therefore developed an algorithm that did not rely on density coefficients, but used the same two-dimensional area obtained in the standard heart scan score, but replaced the density coefficient with a (mathematically interpolated) vertical axis (z-axis) measure of plaque "height." This 3-dimensional volumetric value therefore provided a method to generate a measure of calcium volume. In their original publication, the volume score proved more reproducible than the standard calcium score. This way, any reduction in plaque volume would not be influenced by the misleading effects of calcium density, but reflect a real reduction in volume.

Callister and Raggi's study also highlighted that calcium scoring in any form is subject to variability. Back in 1998 (when their study was published), there was a bit more variation than today due to the image acquisition methods used. But, even today, there is about 9% variation in scoring even if performed repeatedly (with less percentage variation the higher the score).

Unfortunately, volume scoring never caught on and the calcium score has been the most commonly used value by most heart scan centers and in most clinical studies. And, in all practicality, the two values nearly always track together: When calcium score increases, volume score increases in tandem; when calcium score decreases, volume score decreases in tandem.

Steve is therefore an exception to the general observation that calcium score and volume score travel together. Steve's calcium score increased, while his volume score decreased. From the above discussion, you can surmise a few things about Steve's experience:"

1) In all likelihood, the changes in both calcium score and volume score could simply be due to variability, i.e., variation in the placement of his body on the scan table, variation in position of the heart, variation in data acquisition, etc. There is a high likelihood that neither value changed; both are essentially unchanged.

2) If the changes are not due to scan variability, but are real, then it could be that the calcified plaque is reduced in volume but increased in density. If true, this is probably still a favorable phenomenon, since plaque volume is a powerful predictor of coronary "events" and an increase in plaque density is likely a benign phenomenon. It would also raise questions about the adequacy of vitamin D and vitamin K2 status, both major control factors over calcium deposition and metabolism.

So, in all likelihood, Steve's apparent discrepant results are modest good news, especially since calcium scores can ordinarily be expected to increase at the rate of 30% per year if no action is taken. Experiencing no change in score, calcium or volumetric, carries a very excellent prognosis, with risk for heart attack approaching zero. (I'm impressed that Steve accomplished this on his own, something the majority of my colleagues haven't the least bit of interest doing.)

Part 2 of Steve's question will be tackled in a separate post.

Can I see your linea alba?

2. November 2010 William Davis (19)
As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba.

Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen.

It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors.


Can you see your linea alba?

Dwarf mutant wheat

31. October 2010 William Davis (13)
Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.

Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant. 

Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to. 





The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans.

Medical education in the days of Big Pharma

30. October 2010 William Davis (43)
I received this detailed email from an unexpected source: a 3rd-year medical student.

In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life.

Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat.

While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career.


Dr. Davis,

I am a 3rd year medical student at ________ University. I came across
your blog today, and I'm very glad I did. I appreciate the value of your time,
so I want to be as succinct as possible while still getting across what I'm
really thinking and feeling:

From what I gathered exploring your blog for a while this afternoon, the
wellness strategies you incorporate into your practice are some of the exact
things I want to do with my future patients. Personally, I strongly believe in
staying healthy by eating right, staying active, etc. For instance, I don't eat
grains or much in the way of starches and sugars. So I love the fact that you
are helping your patients make these powerful and foundational changes in their
lives.

As I'm sure was your experience, a full appreciation of nutrition and lifestyle
as a first-line health strategy is not something that was taught to me in
medical school. I came to school with this deep conviction already in my heart
and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss
as to how I'm going to be able to practice medicine the way I want to, which is
to incorporate these all-important principles into the care of my patients.

What I've come to understand about the medical field today is that the
information that exists is primarily subsidized by the pharmaceutical industry,
and dictated to medical professionals as "evidence-based" treatment guidelines
and recommendations by organizations with sincere and official sounding names
like American Heart Association and American Cancer Society. Add to that the
pressure of potential malpractice litigation and the complexities of the
insurance reimbursement game, and it seems to me like what you get is a bunch of
diagnostic and medication management algorithms that any half-trained monkey
could follow. In his sleep. Which I guess would be alright if at least they
weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma,
Food Inc, insurance conglomerates, and agri-politics (I think I just made that
word up.)

A lot of well-intentioned physicians are just parroting the party
line, as their patients dutifully and gratefully chomp down their statins and
diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes
education" programs with curriculum put together by drug companies? How is that
even legal? Massive corporations raking in massive profits that are dependent
on uncontrolled blood sugars telling people how to best control their blood
sugars?!

Anyway, forgive my rant. What I'm getting at is this: How can I practice
medicine, with the freedom to educate/coach/treat my patients with diet and
lifestyle changes to mitigate/reverse their chronic health conditions? Without
feeling like I automatically have to first and foremost prescribe the litany of
drugs dictated by "evidence-based" guidelines? Without excessive fear of
litigation or loss of credibility among my peers? Without having to lie through
my teeth to my patients, and tell them that eating low-fat and heart-healthy
whole grains is the best way (implication also being the only scientifically
proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?

I want my patients to have the full benefit of honest nutrition and lifestyle
information, and medications and surgery as necessary. I'm afraid that there
isn't room for this kind of holistic emphasis in the medical profession today.
Are there residencies that include this kind of training or at least respect
these "unconventional" philosophies? Are there clinics or practice groups that
would allow me to practice with this emphasis, or is there a bias against docs
who do not necessarily conform to the party position? Will I have no other
option but to go it alone under the auspices of my own shingle? How do you
handle these kinds of issues in your professional life?

Sincerely,
Theresa M.


A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets.

I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often.

The Great Low-Carb Connector

28. October 2010 William Davis (15)
The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.

Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:

My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!

This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”

Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible.

New Track Your Plaque record!

27. October 2010 William Davis (19)
The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score.

Well, the longstanding record was broken this week: 75% reduction in score.

At the start, Freddie has disastrous lipid values:

LDL cholesterol 263 mg/dl
HDL 26 mg/dl
Triglycerides 323 mg/dl
Total cholesterol 354 mg/dl

Lipoproteins (NMR) were worse:

LDL particle number 3360 nmol/L
Small LDL 2677 nmol/L

Heart scan score: 732

Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable.

Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me.

Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight.

43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction.

While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees.

The Anti-AGEing Diet

22. October 2010 William Davis (36)
Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck.

There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others.

One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)

There are two general ways to develop AGEs:

1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months.

A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation.

2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi.

The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation.

Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food.

If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy.

The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs.

More on being wheat-free

21. April 2007 William Davis (5)
Reducing or even eliminating the wheat in your diet can dramatically enhance the phenomenon of insulin resistance.

Insulin resistance is the evil process that lies behind low HDL, high triglycerides, small LDL particles, and VLDL and IDL. It’s also the process that makes us tired after meals, heightens inflammation that raises your risk of heart disease, stroke, diabetes, and caner. Insulin resistance is the culprit behind the bulge hanging over some 100,000,000 American belts.

Show me a person with a protruding abdomen and I’ll show you a bread lover, or some other form of wheat.

Why do I pick on wheat so much? Many of you among the more nutrition-minded would point out that wheat is just one group of food items among many other high-glycemic index foods, i.e., foods that yield a vigorous surge in blood sugar (glucose), followed by a sharp decline. Wheat enjoys the high-glycemic index company of corn, rice (white and brown), potatoes, among others.

I pick on wheat because, for most Americans, wheat is 90% of the high-glycemic index problem. (I’m assuming you’ve at least eliminated or dramatically reduced highly-processed sweets like candy, cookies, soft drinks, cakes, etc. That’s a no-brainer.) It’s not uncommon to have a wheat-based product with every meal, a wheat-based snack, 7 days a week. But few people have corn products (i.e., corn starch products) three times a day. Or rice three times a day.

Wheat has traded places with saturated fat sources as the chief scourge of diet. In 1985, we had dinners of spare ribs, cheeseburgers, French fries, and butter on our mashed potatoes. Hardly anybody eats that like anymore, at least amongst the web-savvy set.

Wheat has assumed the previous exalted role as chief scourge as a consequence of the low-fat consciousness of the 80s and 90s. It has since ballooned in importance in diet and, as a result, skyrocketed as a cause of obesity, insulin resistance, and coronary plaque growth.

What if you're already slender and have none of the above issues, especially small LDL particles? Then don't sweat the wheat issue.

Note: My comments on being wheat-free should not be confused with gluten sensitivity or celiac disease. These are allergies to wheat gluten that, if undiagnosed, wreak havoc on health to extremes. This phenomenon is separate and distinct from the far more prevalent issue I’m discussing.

Can you break the “Rule of 60”

21. April 2007 William Davis (1)
In the Track Your Plaque program, we aim for conventional lipid values (LDL cholesterol, HDL cholesterol, and triglycerides) of 60—60—60, i.e., LDL 60 mg/dl, HDL 60 mg/dl or greater, triglycerides 60 mg/dl. Most participants do indeed reach these target values.

When I tell this to colleagues, they’re stunned. “You can’t possibly get those numbers in most people.” And I can sympathize with their plight. After all, they are stuck with relatively lame tools: statin drugs, the American Heart Association diet. I’d be surprised if they ever achieved 60—60—60.

But can you drop your heart scan score even if you don’t reach the 60—60—60 targets? Yes, you can. The Rule of 60 is only a guideline, a tool that helps more people achieve our goals. The Rule of 60 does not guarantee reversal (drop in heart scan score), nor does not achieving the targets completely destroy your chances.

We have had many people drop their scores even if they haven’t reached the targets. On the other hand, we’ve also had people who failed at first, only to see success once they achieved the 60 mg/dl targets.

But which one are you? That’s the problem. We possess limited capacity to predict who will or who will not drop their scores from the start. We know that there are factors that stack the odds in your favor (e.g., optimism, lack of Lp(a), ideal weight, vitamin D >50 ng/ml, etc.). We know that there are factors that make it tougher (overweight, Lp(a), pessimistic attitude, underappreciated hypertension, higher heart scan scores, etc.) But at the start, we just don’t know who truly needs to adhere to the Rule of 60. So we suggest that everyone, at least in the beginning, aim to achieve it.

I had an exception the other day. Rich did everything by the Track Your Plaque book. However, a starting low HDL of 27 only rose to 37 after one year of effort—way below our 60 mg/dl target. Yet a repeat heart scan showed 23% reduction.

Why would Rich be so successful despite a persistently very low HDL? There may be a number of reasons. One explanation could be that conventional measures of HDL fail to distinguish between what HDLs truly work and what do not. Look at ApoA1 Milano; remember this story? The people in the secluded mountain village of Limone-Sul-Garde in northern Italy have HDL cholesterols of 8-15 mg/dl yet do not experience excess vascular atherosclerosis, suggesting that what little HDL they have is super-effective.

Yes, large HDL seem to be more healthy and effective than small HDL, but perhaps there’s more to it. However, nobody has a HDL effectiveness test ready for us to use.

In the meantime, we continue to suggest that the Track Your Plaque Rule of 60 be considered as a means of making plaque reversal as likely as possible. You and your doctor can always adjust in future, depending on your heart scan score results.

Non-profit hospitals

21. April 2007 William Davis (1)
Hospitals hide behind a veil of non-profit.

Ostensibly operating for the public good, most hospitals enjoy all the business advantages of non-profit status. This means that any profits that flow to the bottom line at the end of the year are not subject to tax. Hospitals point out that profit margins are modest, often ranging from 2-6%.

What they don’t tell you is that, regardless of non-profit status, lots of money can be paid out along the way. A hospital CEO who pays himself $4 million dollars a year can work for this non-profit organization. He can also direct the hospital in business expansion: pharmacies, extended-care facilities, medicine and medical supply distributorships. Your friendly hospital CEO, as well as his many administrators, can hold positions in hospital subsidiaries, complete with salaries and perks.

Yes, most hospitals are officially non-profit. But that’s a designation for tax purposes. It does not mean that hospitals are non-lucrative.

I believe that it’s time for hospitals to drop the façade of “Saint” in their names or other religious names—Methodist, Baptist, Jewish, All Saints’. More accurate would be something like “ABC Medical Enterprises, Inc.” That way, the public would be quicker to recognize that they are dealing with a business run by people eager to make more money.

Wheat five times a day

20. April 2007 William Davis (3)
Terri couldn't understand why her weight wouldn't drop.

At 5'3", 208 lbs., she had the typical mid-abdominal excess weight that went with small LDL, low HDL, high triglycerides, a post-prandial (after-eating) fat clearance disorder, high blood sugar, increased c-reactive protein, and high blood pressure.

She claimed to have tried every diet and all had failed. So we reviewed her current "strict" diet:

"For breakfast, I had Shredded Wheat cereal in skim milk. No sugar, just some cinnamon and a little Splenda. For lunch, I had low-fat turkey breast sandwich--no mayonnaise--on whole wheat bread. For snacks, I had pretzels between breakfast and lunch, and a whole wheat bagel with nothing on it before dinner. For dinner, we had whole wheat pasta with tomato sauce and a salad. While we watched TV, I did have a couple of whole wheat crackers.

"I don't get it. I didn't butter anything, I didn't sneak any sweets, cakes, I didn't even touch cookies. And I love cookies!"

Did you see the pattern? I pointed out to Terri that what she was doing, in effect, was eating sugar 5 or more times a day. Many of her meals, of course, contained no sugar. All were low fat. But the excessive wheat content yielded quick conversion to sugar--glucose--immediately after ingestion.

Repeated surges of blood sugar like this trigger the excessive insulin response that yields low HDL, higher triglycerides, small LDL, etc., everything that Terri had.

Terri was skeptical when I suggested that she attempt an "experiment": Try a four week period of being entirely wheat-free. This meant more raw nuts and seeds, more lean proteins like low-fat yogurt and cottage cheese, chicken, fish, lean red meats, more vegetables and fruits.

After only two weeks, Terri dropped 5 1/2 lbs. She also reported that the mood swings she had suffered, afternoon sleepiness, and uncontrollable hunger pangs had all disappeared. The mental cloudiness that she had experienced chronically for years had lifted.

What happened was that the load of sugar from wheat products, followed by an insulin surge then a precipitous drop in sugar, and finally fogginess, irritability, and cravings for food all disappeared. With it, the entire panel of downstream phenomena (small LDL, CRP, etc.) all faded.

Though she started out intending to complete a four week trial, I believe that, having seen the light, she will continue to be wheat-free, or nearly so, for a lifetime.

The battle for natural hormones

18. April 2007 William Davis (0)
The battle for preservation of availability of compounded natural hormones goes on.

It started with pharmaceutical manufacturer, Wyeth, who petitioned the FDA to disallow the mixing of pharmaceuticals, especially natural human hormones, by specially trained pharmacists at what are called "compounding pharmacies." These are pharmacies that have special equipment and where trained pharmacists can mix up specific preparations for dispensing. These are available by prescription.

For instance, I have been prescribing natural human testosterone and progesterone for nearly 10 years. I have found service to be excellent, with lots of learning materials provided to patients by the pharmacy. The pharmacists I've spoken to have been courteous and knowledgeable. Compounded hormones are also shockingly less expensive. While a testosterone patch from a pharmaceutical company costs around $4.00 per day, the same quantity of testosterone cream formulated by a compouding pharmacy costs around $0.50 per day--87.5% less.

Wyeth hides behind a smoke screen of concern over quality. But the price differences tells the entire story: they want to eliminate the inexpensive competition and hold us all hostage to the far more expensive, often inferior products that they produce. They'd sooner force a woman to use horse-derived Premarin than to allow her access to human estrogens and progesterone.

To me, this is an outrageous affront to our freedom of choice, both as consumers as well as a physician. If you feel as strongly as I do about opposing the unfair and bullying ways of Wyeth Pharmaceuticals and the FDA, the P2C2 association of compounding pharmacists makes writing a letter to your Senator easy by going to

Lipitor and memory

17. April 2007 William Davis (2)
At first, I was skeptical. A book from a nutty author and physician named Duane Graveline kept on coming up in conversations with patients. His book, Lipitor: Thief of Memory , details his personal experience with dramatic changes in memory and thought while taking Lipitor.



Now this is a drug that I've seen used thousands of times. But I've now seen about a dozen people who have had distinct struggles with memory and clarity of thinking while taking Lipitor. Most took doses of 40 mg per day or more, though an occasional person takes as little as 10 mg. The association seems to be undeniable, since it improves after two weeks off the drug, recurs when resumed. Just today, I saw two people where this effect may be an issue.

Curiously, I've not seen it with any other statin agent. Unfortunately, uncovering any scientific data on the issue is a hopeless quest. Either it's very uncommon or, worse, the data has been suppressed.

Any way, I believe that Dr. Graveline was right: Lipitor, in a small number of people, does indeed seem to exert real detrimental effects on the mind.

If you take Lipitor, should you stop it in fear of long-term effects on your mental capacity? I think it's premature to toss the drug out based on this relatively uncommon relationship. This particular effect is likely to be idiosyncratic, i.e., peculiar to an occasional person but does not seem to apply to the majority, probably by some quirk of metabolism or penetrability of the barrier between the blood and nervous system tissue.

If, however, you feel that your thinking and memory have deteriorated on the drug, please speak to your doctor.

EKG's and heart disease

16. April 2007 William Davis (6)

How helpful are EKG's for detecting hidden heart disease?

I pose this question because several patients asked this question just this week. It's also a frequent point of confusion and misperception.

Your EKG is nothing more than an expression of the surface electrical activity emitted by heart muscle activity. Multiple (12) leads are attached to the body simply to provide various "views" of this electical activity. EKG, or sometimes "ECG", is short for "electrocardiogram".

What modifies this surface electrical activity? Anything that modifies the electrical activity within the heart itself, or interferes with the detection of the activity. An old heart attack modifies the patterns of electrical conduction in the heart and that can change your EKG. An ongoing heart heart attack likewise. High blood pressure commonly creates changes in the EKG, as does lung disease. A bellyache can change your EKG, as can a stroke. (These non-heart-related phenomena probably are often due to changes in autonomic, or "automatic," nervous system activity.) The heart generates electrical activity in a predictable sequence that generates the heart beat, or "rhythm". EKG's are useful for monitoring heart rhythm, also.

Does having plaque in your coronary arteries have any effect on the EKG? None whatsoever, unless plaque rupture caused heart attack or is about to cause heart attack. So, you can have a horrendous CT heart scan score of, say, 3000, yet maintain a perfectly normal EKG, as long as the heart muscle is normal.

Then why bother with these iffy tests? They are indeed useful to diagnose the cause of active symptoms. For instance, go to the ER with chest pain and an EKG could show changes suggesting that the chest pain is a heart attack. EKG's are also useful for future comparison. Any change in EKG can suggest certain things, like new heart rhythm disturbances unrelated to coronary plaque.

Think of your EKG as just like buying a used car. Say I'm trying to sell you my 1999 Buick Century. It looks pretty good from the outside and I tell you that it has 70,000 miles and runs well. You ask to open the hood, look in the interior and take it out for a drive. I tell you no, you can't do that.

Would you buy the car? Of course you wouldn't. You were permitted only a very superficial examination of the car. You have no idea what's going on inside. Just because the paint job looks brand new doesn't mean the engine and transmission are good.

The same with your EKG: It's a superficial look at one aspect of this used car called your heart. If the EKG is normal, that's good, just like a good exterior on the Buick. But you cannot assume that the heart is otherwise normal.

View the EKG as a simple, superficial test that can only provide minimal reassurance, no matter how often you have it done.

A new Track Your Plaque record

14. April 2007 William Davis (0)
Neal, a 40-year old school principal, and his young wife were terrified on learning of his CT heart scan score of 339, a concerningly high score for any age, particularly age 40.

To make matters worse, all of Neal's plaque was located in the critical left mainstem coronary artery, the shared stem of two of the three coronary arteries. A heart attack in this location is instantly fatal.

So, it was especially gratifying that Neal has set the Track Your Plaque record for largest magnitude of plaque reversal: 51% in his first year.

Studies that show a reduction in heart attack make the news. They talk about 1, 2, up to 6% regression, all achieved with high doses of statin drugs. Yet we are seeing huge, extraordinary quantities of heart disease reversal that haven't yet made headlines, amounts that far exceed those featured in the news. We should be encouraged by experiences like Neal's.

Watch for the upcoming Track Your Plaque newsletter for more details on Neal's story--how he came to the program, how he accomplished this huge effect, and why his experience was such a success.

The Plavix Scam

12. April 2007 William Davis (3)
Periodically, I'll see a flurry of TV ads for Plavix. It comes with a polished computer-animated cartoon that shows how platelets clump and form a blood clot, causing heart attack.

Imagine there's a pile of oil-soaked rags in a corner of your garage. I come by and tell you to get a good fire extinguisher to keep next to the rag pile in case they spontaneously ignite.

Does that make sense to you?

Wouldn't it be better to get rid of the oily rags and forget about the fire extinguisher?

Plavix is the fire extinguisher. The oil rags are your coronary plaque. The solution is to gain control over plaque behavior. Unfortunately, the TV ads (intentionally, I suspect) give the impression that blood clots just form out of the blue for no reason. Of course that's not true. It requires active, growing, inflamed atheroslcerotic plaque that ruptures, uncovering the "angry" and platelet-adhering material underneath the thin covering or endothelial lining.

Urging everybody to take Plavix is absurd. The TV ads urge many people who have no business taking the drug to take it. There are, without a doubt, groups of people who are better off taking Plavix and aspirin: people who are in the midst of heart attack, people who have unstable plaque, people with recent stents or bypass. Perhaps people at high risk for plaque rupture, e.g., extensive coronary plaque that has continued to grow.

These tactics are consistent with the experiences I've had with the sales representatives from the company (when I used to actually talk to sales reps; my office is now barred from them). The reps very aggressively would urge me to consider having everyone take Plavix. No kidding.


For us, i.e., for people who just have a heart scan score but interested in engaging in a powerful program of prevention and reversal, Plavix rarely provides any advantage. The answer is, just like our oily rag analogy, control the plaque, not put out the fire.

Lipoprotein(a) and small LDL

11. April 2007 William Davis (0)
You won't find a lot of scientific validation for this, but it is my firm impression that small LDL, by some crazy means, has the capacity to "turn on" or "turn off" lipoprotein(a), Lp(a).

Recall that Lp(a) is a specific genetic trait, passed to us (if you have it) by mother or father. It falsely elevates LDL cholesterol and escalates heart disease risk more than just about any other known abnormality.

A frequent hint that Lp(a) might be present is a comment I hear often from patients: "My doctor said statin cholesterol drugs don't work for me. I tried them all and my cholesterol won't go down." Or, the result was substantially less than expected. That's because, when Lp(a) is lurking in your cholesterol value, it is unaffected by the statins.

It's been my in-the-trenches observation that, the more fully expressed the small LDL pattern becomes, the worse the Lp(a) behaves. In other words, if small LDL is suppressed effectively, Lp(a) doesn't seem to carry the same dangers as in someone who has plenty of small LDL. I don't know why this is. (I expect that the answer will come from someone like Dr. Marcovina at Stanford, who is at the forefront of Lp(a) structural research. Lp(a) is a complex molecule with several components. How and why it interacts with other particles remains a mystery.)

There are a little bit of data to confirm this. The Quebec Cardiovascular Study has presented some data to this effect, that the combination of small LDL particles and Lp(a) are a particularly lethal combination. We are trying to correlate our data from a CT heart score perspective to discern any statistical relationships.

This raises a very important therapeutic issue if you have Lp(a): the worst thing you can do if you have Lp(a) is become overweight. Excess abdominal fat is a huge trigger to create small LDL particles. Even though being overweight itself has no effect on the measured level of Lp(a), it activates small LDL which, in turn, throws gasoline on the Lp(a) fire.

If you have Lp(a), stay skinny.
