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.

Butter: Just because it's low-carb doesn't mean it's good

21. October 2010 William Davis (59)

The diet I advocate in the Track Your Plaque program to gain control over the factors that lead us to coronary plaque and heart attack is a low-carbohydrate diet. We begin with elimination of wheat, cornstarch, oats, and sugars in the context of an overall carbohydrate-reduced diet. We refine the program by monitoring postprandial (after-meal) glucoses.

But not everything low-carb is good for you. Fried sausages, for instance, are exceptionally unhealthy, despite having little to no carbohydrates.

An emerging but potentially very powerful issue is that of Advanced Glycation End-products, or AGEs. There are two general varieties of AGEs: endogenous (formed within the body) and exogenous (formed in food that is consumed).

Endogenous AGEs form in the body as a result of high blood glucose, i.e., glycation. When exposed to any blood glucose level of 100 mg/dl or greater, some measure of glycation will develop due to a reaction between glucose and various proteins, e.g., proteins in the lens of the eye, forming cataracts over time.

Exogenous AGEs form in food, generally as a result of heating to high-temperature. (AGEs is really a catch-all term; there are actually a number of reactions that occur in foods, not all of them involving sugars. However, the "AGE" label is used to signify all the various related compounds. The values quoted here are from Dr. Helen Vlassara's Mt. Sinai Hospital laboratory; reference below.)

Beef cooked to high-temperature yields plentiful AGEs. One gram of roast beef, for instance, contains 306,238 units. This means that an 8-oz serving yields 13.8 million units AGEs. Compare this to a boiled egg with 573 units per gram, raw tomato with 234 units per gram.

Butter contains an impressive 264,873 units AGEs per gram, the highest content per gram in the entire list of 250 foods tested in the Mt. Sinai study. A couple pats of butter (10 g) therefore contains 2.64 million units. A stick of butter that you might add to cake batter to make a cake therefore yields 30 million units of AGEs.

So there's nothing wrong with the fat of butter. It's AGEs that appear to be responsible for the endothelial dysfunction/artery-constricting, insulin-blocking, oxidation and inflammation reactions that are triggered. Among all of our food choices, butter is among the worst from this viewpoint.

Throw in the peculiar "insulinotrophic" effect of butter, and you have potent distortion of metabolic pathways, courtesy of the butter on your lobster.

(AGE data from Goldberg 2004. In this analysis, carboxymethyllysine was the marker used for AGE content.)

Incidentally, the new Track Your Plaque diet will soon be released as chapter 9 of the new Track Your Plaque book on the website.

Einkorn now in Whole Foods

16. October 2010 William Davis (19)

I just saw this at Whole Foods: einkorn pasta.

In my einkorn bread experience (In search of wheat: We bake einkorn bread), I was spared the high blood glucose and neurologic and gastrointestinal effects of conventional whole wheat grain (dwarf Triticum aestivum). I shared the einkorn bread with four other people with histories of acute wheat sensitivities, only one of whom experienced a mild diffuse joint reaction, the other three not experiencing any symptoms.

Anyone wishing to try einkorn can now obtain commercial pasta from Jovial, an Italy-based manufacturer. It comes in spaghetti, linguine, rigatoni, fusilli, and penne rigate shapes.

Eli Rogosa, founder of The Heritage Wheat Conservancy, tells me that, in her experience, celiac suffers seem to not experience immunologic phenomena triggered by conventional wheat.

However, we've got to be careful here. The so-called ("diploid") "A" genome of einkorn shares many of the same genes as the ("hexaploid") "ABD" genomes of modern wheat, including overlap in the sequences coding for the 50-or so different glutens and glutenins. Most of the genes that code for the glutens that cause celiac and related illnesses reside in the "D" genome that are absent in the einkorn "A" genome. However, the "A" genome still codes for glutens. So there is potential for activating celiac disease in some people. Insufficient research has been devoted to this question. It is a question of extreme importance to people with celiac and other immune-mediated conditions, since re-exposure to the wrong form of gluten can increase risk of intestinal lymphoma 77-fold, as well as risk of other gastrointestinal cancers.

So einkorn should not be viewed as a cure-all for all things wheat, but as something to consider for a carbohydrate indulgence. Yes, indeed: It is a carbohydrate, with 61 grams ("net") carbs per 4 oz (uncooked) serving.

Should anyone give it a try, please be sure to report back your experience, especially if you have a history of wheat intolerance. If you have a glucose meter, pre- and 1-hour post values are the ones to measure to gauge the blood sugar effects of consumption. Because pasta tends to cause long sustained blood sugar rises, another value at 2-4 hours might be interesting.

Noodles without the headaches

14. October 2010 William Davis (26)

If you are looking for a wheat-free noodle or pasta, shirataki noodles are worth a try.

Shirataki noodles are low-carbohydrate (less than 3 g per 8 oz package) and, of course, do not trigger all the unhealthy effects of wheat--no blood sugar/insulin provocation, no addictive brain effects (exorphins), no gluten-mediated inflammatory effects.

(I advise avoiding gluten-free pasta alternatives made with rice flour and other common gluten alternatives, since they trigger blood sugar, small LDL, and growth of visceral fat just like wheat.)

I made a stir-fry using the shirataki-tofu noodles, shown below. (Tofu is added to make the noodles more noodly in consistency, as opposed to the chewier non-tofu variety.) The noodles were a lot like the ramen I used to eat as a kid. They were filling and tasted great in the sesame oil, soy sauce, tofu, and vegetables I used.

The noodles are easy to use. Just drain liquid out of package. (The noodles come in water.) Rinse in collander 30 seconds, then boil for 3 minutes. Add to your stir-fry or other dish. Some manufacturers, such as House Foods, also have angel hair and fettucine style noodles.

You're fried

13. October 2010 William Davis (26)

If I could invent a food that illustrates nearly all of the shortcomings of the American diet, it would be French fries, the familiar fixture of fast food.

What we have come to view as French fries contain just about every one of the unhealthy ingredients that lead us down the path of obesity, diabetes, heart disease, high blood pressure, etc.

Let's take them one by one:

Potato starch--Potato starch exerts an effect on blood sugar similar to that of table sugar, only worse. (Glycemic index french fries 75; glycemic index sucrose 65.)

Advanced Glycation End-products (AGEs)--AGEs form when proteins and fats are subjected to high temperature cooking; the longer the high temperature, the more the food reaction creating AGEs proceeds. AGEs are the likely culprit in roasted and fried foods that made it appear that saturated fats were bad, when it was really AGEs all along. AGEs have been shown to block insulin's effects, increase blood sugar, cause endothelial dysfunction and high blood pressure.

Acrylamides--Acrylamides, like AGEs, are created through high-temperature heating. French fries are unusually rich in AGEs. Brewed coffee also contains a small quantity, while French fries contain 82-fold greater quantities, among the highest of all known sources of acrylamides.

Oxidized oils--The amount of oxidized oils will depend on what sort of oil was used for frying. As more restaurants are trying to get away from hydrogenated oils, many are turning back to polyunsaturates. Others are turning to commercial-grade oils that contain both hydrogenated and polyunsaturates. If oils are permitted to oxidize, then they will trigger oxidative phenomena in your body upon consumptions, e.g., LDL oxidation (Staprans 1994).

In other words, the innocent appearing French fry unavoidably triggers oxidation, all the phenomena triggered by high blood glucose (high insulin, glycation, visceral fat accumulation), along with the cascade of effects arising from AGEs and acrylamides.

Top your French fries with some ketchup made with high-fructose corn syrup that exagerrates AGE formation, visceral fat, and distorts postprandial (after-eating) effects.

Is it any wonder that we've lost control over diet?

Indian buffet

24. février 2011 William Davis (56)

I took my family to a local all-you-can-eat Indian buffet. It was delicious.

I confined my food choices mostly to vegetables and soups. Within about 30 minutes, I started to get that odd buzz in my head that usually signals a high blood sugar.

When I got home, my fingerstick blood glucose: 173 mg/dl. Darn it! Must have been cornstarch or other sugars in the sauces.

I got on my supine stationary bike and pedaled for 40 minutes at a moderate pace while I played Modern Warfare on XBox. (A great way, by the way, to fit in some low- to moderate-intensity exercise while occupying your brain. My wife often has to yell at me to get off, it's so much fun.)

Blood glucose at the conclusion of exercise: 93 mg/dl-- a nice 80 mg/dl drop.

This is a useful strategy to use in a pinch when you've either been inadvertently exposed to more carbohydrate than you can tolerate, or if you'd like to blunt the adverse glucose effects of a bowl of ice cream or other carbohydrate indulgence.

Should we explore the idea of a "morning-after" pill, or actually a "meal-after" pill, a supplement pill or liquid that blunts or eliminates the blood glucose rise after a meal? I've considered such an idea, but have been fearful that people would start to use it habitually. Thoughts?

American Heart Association diet makes a monkey out of you

21. février 2011 William Davis (38)

Heart Scan Blog reader, Roger, brought this New York Times article to my attention.

In an effort to develop a better experimental model for obesity than mice, scientists have turned to monkeys and other primates. The emerging observations are eerily reminiscent of what you and I witness just by going to the local grocery store or fast food outlet:

"'It wasn’t until we added those carbs that we got all those other changes, including those changes in body fat,' said Anthony G. Comuzzie, who helped create an obese baboon colony at the Southwest National Primate Research Center in San Antonio."

"Fat Albert, one of her monkeys who she said was at one time the world’s heaviest rhesus, at 70 pounds, ate “nothing but American Heart Association-recommended diet,” she said."

Yes, indeed: The American Heart Association diet makes monkeys fat. Extrapolate this a little higher on the evolutionary ladder and guess what?

This is one of the many reasons why, when I have a patient who is counseled by the hospital dietitian on the American Heart Association diet, I advise them to 1) ignore everything the dietitian told them, and then 2) follow the wheat-free, cornstarch-free, sugar-free, whole food diet I advocate.

Not unexpectedly, much of this primate research is not being devoted to just manipulating diet to achieve weight loss and health, but to develop new drugs to "treat" obesity.

Would you like a banana?

Construct your glucose curve

19. février 2011 William Davis (24)

In a previous Heart Scan Blog post, I discussed how to make use of postprandial (after-meal) blood sugars to reduce triglycerides, reduce small LDL, increase HDL, reduce blood pressure and inflammatory measures, and accelerate weight loss.

In that post, I suggested checking blood glucose one hour after finishing a meal. However, this is a bit of an oversimplification. Let me explain.

A number of factors influence the magnitude of blood glucose rise after a meal:

--Quantity of carbohydrates
--Digestibility of carbohydrates--The amylopectin A of wheat, for example, is among the most digestible of all, increasing blood sugar higher and faster.
--Fat and protein, both of which blunt the glucose rise (though only modestly).
--Inclusion of foods that slow gastric emptying, such as vinegar and fibers.
--Body weight, age, recent exercise

Just to name a few. Even if 10 people are fed identical meals, each person will have a somewhat different blood glucose pattern.

So it can be helpful to not just assume that 60 minutes will be your peak, but to establish your individual peak. It will vary from meal-to-meal, day-to-day, but you can get a pretty good sense of blood glucose behavior by constructing your own postprandial glucose curve.

Say I have a breakfast of oatmeal: slow-cooked, stoneground oatmeal with skim milk, a few walnuts, blueberries. Blood glucose prior: 95 mg/dl. Blood glucose one-hour postprandial: 160 mg/dl.

Rather than taking a one-hour blood glucose, let's instead take it every 15 minutes after you finish eating your oatmeal:

In this instance, the glucose peak occurred at 90-minutes after eating. 90-minute postprandial checks may therefore better reflect postprandial glucose peaks for this theoretical individual.

I previously picked 60-minutes postprandial to approximate the peak. You have the option of going a step better by, at least one time, performing your own every-15-minute glucose check to establish your own curve.

Why is type 1 diabetes on the rise?

16. février 2011 William Davis (43)

Type 1 diabetes, also called "childhood" or "insulin-dependent" diabetes, is on the rise.

Type 2 diabetes, or "adult," diabetes, is also sharply escalating. But the causes for this are easy-to-identify: overconsumption of carbohydrates and resultant weight gain/obesity, inactivity, as well as genetic predisposition. A formerly rare disease is rapidly becoming the scourge of the century, expected to affect 1 in 3 adults within the next several decades.

Type 1 diabetes, on the other hand, generally occurs in young children, not uncommonly age 3 or 4. Type 1 diabetes also shares a genetic basis to some degree. But the genetic predisposition should be a constant. Obviously, lifestyle issues cannot be blamed in young children.
Then why would type 1 diabetes be on the rise?

For instance, this study by Vehik et al from the University of Colorado documents the approximate 3% per year increase in incidence in children with type 1 diabetes between 1978 and 2004:

(From Vehik 2007)

(For an excellent discussion of the increase in type 1 diabetes in the 20th century, see this review.)

This is no small matter. Just ask any parent of a child diagnosed with type 1 diabetes who, after recovering from hearing the devastating diagnosis, then has to stick her child's fingers to check glucose several times per day, mind carefully what he or she eats or doesn't eat, watch carefully for signs of life-threatening hypoglycemic episodes, not to mention worry about her child's long-term health. Type 1 diabetes is a life-changing diagnosis for both child and parents.

Various explanations have been offered to account for this disturbing trend. Some attribute it to the increase in breast feeding since 1980 (highly unlikely), exposure to some unidentified virus, or other exposures.

I'd like to offer another explanation: wheat.

Lest you accuse me of becoming obsessed with this issue, let me point out the four observations that lead me to even consider such an association:

1) Children diagnosed with celiac disease, i.e., the immune disease of wheat gluten exposure, have 10-fold greater likelihood of developing type 1 diabetes.

2) Children diagnosed with type 1 diabetes are 10-fold more likely to have abnormal levels of antibodies (e.g., transglutaminase antibodies) to wheat gluten.

3) Experimental models, such as in these mice genetically susceptible to type 1 diabetes, showed a reduction of type 1 diabetes from 64% to 15% with avoidance of wheat.

4) The increase in type 1 diabetes corresponds to the introduction of new strains of wheat that resulted from the extensive genetics research and hybridizations carried out on this plant in the 1960s. In particular, unique protein antigens (immune-provoking sequences) were introduced with the dwarf variant attributable to alterations in the "D" genome of modern Triticum aestivum.

Proving the point is tough: Would you enroll your newborn in a study of wheat-containing diet versus no wheat, then watch for 10 years to see which group develops more type 1 diabetes? It is a doable study, just a logistical nightmare. Perhaps the point will be settled as more and more people catch onto the fact that modern wheat--or this thing we are being sold called "wheat"--is a corrupt and destructive "foodstuff" and eliminate it from their lives and the lives of their young children from birth onwards. Then a comparison of wheat-consuming versus non-wheat-consuming populations could be made. But it will be many years before this crucial question is settled.

Yet again, however, the footprints in the sand seem to lead back to wheat as potentially underlying an incredible amount of human illness and suffering. Yes, the stuff our USDA puts at the bottom, widest part of the food pyramid.

Apo E4 and sterols: Lethal combination?

11. février 2011 William Davis (24)

Phytosterols, or just "sterols" to its friends and neighbors, are a group of cholesterol-like compounds that are abundant in the plant world. Lately, however, sterols have proliferated in the processed food supply, thanks to the observation that sterols reduce LDL cholesterol when ingested by humans.

This must mean that sterols are good for you.

Uh oh. Wait a minute: There is a rare disease called sitosterolemia in which there is unimpeded intestinal absorption of all sterols ingested through diet. They must have really low LDL cholesterols! Nope. They develop coronary disease--heart attacks, angina, etc.--in their late teens and 20s. In other words, if sterols gain access to your bloodstream, they are bad. Very bad.

Conventional thinking is that only a modest quantity of dietary sterols gain access to the bloodstream. But there are two potentially fatal flaws in this overly simplistic line of thinking:

1) What happens when you load up your diet with "heart healthy" sterols, such as those in "heart healthy" margarines, mayonnaise, and yogurt, effectively increasing sterol intake 10-fold?

2) What happens in people with the genetic pattern, apo E4, that is carried by 25% of the general population that permits much greater intestinal absorption of sterols?

My prediction: Despite the fact that sterols reduce LDL, they may, in certain genetically-susceptible people, such as those with apo E4, increase risk for heart disease: heart unhealthy.

Here are two studies that suggest that greater sterol absorption in people without sitosterolemia are at higher risk for heart disease:

Glucomania

8. février 2011 William Davis (52)

As I suggested in a previous Heart Scan Blog post, a glucose meter is your best tool to:

1) Lose weight
2) Cure diabetes
3) Reduce or eliminate small LDL particles
4) Achieve anti-aging or age-slowing effects

But it means getting hold of a glucose meter and applying it in a very different way.

Diabetics typically check fasting morning glucose and again several times during the day to assess medication effects. But you and I can measure blood glucose to assess the immediate effects of food choices--two very different approaches.

The concept is simple: Check a blood glucose just prior to a food or meal of interest, then one hour after finishing.

Let's take two hypothetical breakfasts. First, oatmeal, a so-called "low-glycemic index" food. Slow-cooked, stone ground oatmeal with skim milk, a handful of walnuts, just a few blueberries.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 175 mg/dl

I made those numbers up, but this is a fairly typical response for many adults. (This is why "low-glycemic index" is an absurd notion.) This kind of response causes 1) glycation, the adverse effects of glucose modification of proteins that leads to cataracts, kidney disease, cartilage damage and arthritis, atherosclerosis, skin wrinkles, etc., 2) high insulin response that cascades into fat deposition, especially visceral fat ("wheat belly"), and 3) glucotoxicity, i.e., direct damage to the pancreas that can, over years, lead to diabetes.

Next day, let's try a breakfast of 3-egg omelet made with green peppers, sundried tomatoes, and olive oil.

Blood glucose just prior: 95 mg/dl
Blood glucose one hour after finish: 93 mg/dl

This is a meal of virtually zero-glycemic index. This kind of response triggers none of the effects experienced following the oatmeal. Repeated over time and you fail to trigger glycation, you stop provoking insulin, and visceral fat mobilizes rather than accumulates: you lose weight, particularly around the middle.

We therefore aim to keep the one-hour blood glucose 100 mg/dl or less. If you start with a high fasting blood glucose of, say, 118 mg/dl, then we aim to keep the one-hour after-eating blood glucose no higher than the pre-meal.

It works. Plain and simple.

This makes the primary care docs crazy: "How dare you check your blood sugar! You're not diabetic." In truth, blood glucose meters are relatively simple devices to use. The test strips and lancets will cost a few bucks. (The meters themselves are either low-cost or free, just like Gillette sometimes sends you a beautiful new razor for free but expects you to buy the blades). These are direct-to-consumer products. While a prescription written by your doctor for a glucose meter and supplies helps insurance cover the costs, you can easily get these devices without a prescription. Some stores, like Target, keep their devices out on the shelves with the shampoo and bath soap.

Warning: Anyone taking diabetes drugs will have to consult with their doctors about the safety of such an approach. Because this approach can actually cure diabetes in some people, if you are taking some diabetes drugs, especially glyburide, glipidize, and glimepiride, you can experience dangerously low blood sugars, just as any non-diabetic taking these drugs would.

Diarrhea, runny noses, and rage: Poll results

6. février 2011 William Davis (19)

Here are the results of the week-long poll asking the question:

Have you experienced a wheat re-exposure syndrome?

Yes, undesirable gastrointestinal effects 223 (41%)
Yes, asthma or sinus problems 51 (9%)
Yes, joint pains and/or swelling 85 (15%)
Yes, emotional or other nervous system effects 59 (10%) No, nothing, nada 107 (19%)

No. Wheat is sacred and you're all nuts 13 (2%)

There are several interesting observations to make from this informal poll. First, as I have observed, the most common wheat re-exposure syndrome is gastrointestinal, usually involving cramps, diarrhea, and lame explanations to your dinner partner.

Second most common: joint pains and/or swelling.

Third: asthma or sinus congestion.

The incidence of emotional or nervous system effects surprised me a bit. I didn't expect 10% of people to share this effect. This is an effect I also experience personally, along with the gastrointestinal consequences.

To be sure, this is a skewed poll, since many people likely come to this blog in the first place because of such issues. But I was nonetheless impressed with the relatively modest proportion of people who did not share such a re-exposure syndrome: only 19%.

Beyond the interesting numbers provided by readers, a good many also provided some fascinating and graphic comments. Here's a sample:

Sassy said:

Reflux -- starts a day later and goes for up to a week. And Bloat:2-5 inches on my waistline in a day, lasting up to three. Miserable. And why, having experienced this once, have I done it often enough to verify the connection with certainty? I am working on that one.

Wheat increased hunger with even with only a small amount. Crackers in soup was enough to set it off.

Also, when I was trying to get off wheat, I noticed that 2 eggs and 2 bacon and I could go 5 hours before hunger, or 2 eggs and 2 bacon and toast was good for three hours before hunger. That was the final step to giving up wheat. Now three years and 59 Kg [130 lbs!] loss later, there is no doubt in my mind that wheat is evil, and I do not regard it as suitable for human food. I speculate that it increases ghrelin or cortisol.

Anna said:

For me, in the two years since I began eating Gluten-Free (Low Carb for 6 years), the few times I've had re-exposure to wheat, I've experienced fast onset and intense abdominal pain (known exposure during the daytime) and heartburn, indigestion, intense nausea, and disrupted sleep (exposures during evening meal not discovered until the next day).

My husband wants to think he's fine with wheat (though I know that he has at least one gene that predisposes to celiac), but IMO, he isn't. He eats no wheat at home because that's the default, and he's OK with that. But if he goes out to dinner at a restaurant that serves "good" artisan bread, he will indulge in a few bites (he does restrict his carb intake, so it's still a limited amount). More often than not, he will sleep fitfully on those nights, snore more, and wake in the night with indigestion. He wants to bury his head in the sand and will only acknowledge the discomfort being due to eating too many carbs, not the wheat itself. I notice he sleeps fine if he eats a small amount of potato or rice. Go figure.

Our 12 yo son has been eating GF for two years also. About 6 months into GF, he unknowingly ate wheat a number of times (licorice candy laces at a friend's house), which resulted in outbreaks of canker sores in his mouth each time. He also exhibits mood and behavior changes when he eats wheat, which is what prompted me to test him for gluten intolerance in the first place.

Mark said:

If I go for 3-4 days without wheat, grains or sugar and then go out and binge on a pizza and ice cream or something like that I become explosive within 20 minutes to an hour. It's like a wheat and sugar rage.(I'm not saying this is an excuse for rage, I'm saying it has happened to me and I believe partly do to re-exposure) It seems the combination of the wheat plus sugar can be the worst.

I get red rashes around my neck sometimes right away and sometimes up to a day or later and sometimes get bad diarrhea.

I think it can be almost dangerous to cut things like gluten and sugar suddenly out of the diet without being very serious about keeping them out. I have found it very hard to cut out wheat without binging on it later after 4 or 5 days. I don't believe that my symptoms are just psychological either.

I was also diagnosed with ADHD as a young kid and then rediagnosed with adult ADHD by 3 different doctors. I also have bouts of mania at times too. I am considering trying to go completely gluten/refined carbohydrate free to see if it helps with the symptoms and gives me some relief.

I have never been tested for celiac or gluten intolerance but I would like to be. I think it would help explain to my girlfriend, family and friends why I can't go out and eat pizza or have a beer or ice cream. Right now they all think I'm a hypochondriac. At times I have experienced an intense fatigue the next day like I can't wake up and also sharp pains in my body and headaches.

Anonymous said:

I ditched wheat a year ago after my wife was diagnosed celiac. I immediately experienced a number of health improvements (blood lipids, sleep, allergies, etc.).

Fast forward: We all suffered some inadvertent wheat exposure yesterday via some chocolate covered Brazil nuts (of all things). This accidental A-B-A experimental design resulted in the following:

1. My celiac wife experienced what she calls "the flip" within an hour of exposure (i.e., intense GI distress).
2. My five-year old son went to bed with some wicked reflux.
3. I woke up with some twinges in my lower back and an ache in my football-weary left shoulder. I was also complaining to my wife about fuzzy-headedness that refused to respond to caffeine or hydration. I could only describe it as "carb flu"...

And then I read your post!

Anne said:

Depression, agitation and brain fog if I get glutened. Some times this comes with abdominal pain and a rash on my back - I think it is dose dependent. Cross contamination with wheat is a big issue when eating out. Needless to say, I eat out infrequently and then try to stick with the restaurants that are the most aware of gluten issues.

Terrence said:

Several weeks ago, I started Robb Wolf's 30 day challenge.

The first two weeks were brutal - calling it a withdrawal flu was a massive understatement. So, I thought I would try some wheat and see what happened (could not be worse, I thought). Well, it was.

I still felt extremely crappy, but I was now MASSIVELY GASSY - AMAZINGLY GASSY, for about 48 hours - flatulence on wheels, in spades. I did not go out at all in those 48 hours - when the gas came on, it went out, LONG, and QUICKLY and LOUDLY.

I am easing back into wheat and grain free. I am gluten free today and tomorrow (Sunday and Monday). I expect to try a small amount of wheat on Thursday, then maybe a little more the following Thursday.

Donald said:

I have limited wheat consumption severely over the last 8 months. I have lost 120 pounds, no longer have bouts of illness, asthma, depression, or low energy. I also take vitamin D and other supplements that have helped (many are from your blog recommendations).

Last week I ate a small piece of cake and dessert pizza. Shortly thereafter I started sneezing, had a scratchy throat, and runny nose. I called off sick the next day for fear of being contagious. My symptoms subsided quickly and I am now attributing them to the processed flour eaten at my work luncheon. I think it was an allergic reaction since I recall having much more severe symptoms fairly regularly in my wheat eating days. Those were attributed to an "allergy" of unknown origin back then.

John said:

I suffered from Ankylosing Spondylitis, Iritis, Plantar Fasciits, etc for a number of years. I restricted carbs, especially wheat and I've been symptom free for the past two years now.

Lori said:

I found wheat to be one of the worst things for giving me gas bloating and acid reflux, and I'd had sinus and nasal congestion my whole life. When I ate that cookie, it just re-introduced old problems. I can occasionally eat a gluten-free, grainy goody at my party place without any side effects. I also have a little sprouted rice protein powder every day.

Another odd thing about wheat: it was hard for me to stop eating it once I started. I could go through a whole box of cookies in one sitting, even though I wasn't a binge eater. But I can have a couple of gluten-free cookies and stop.

Paul said:

Except for one slip up this recently past holiday season, I've been sugar-grain-starch free since July 2008. Mental fog was the most noticable re-exposure symptom I had.

My mom has had the worst acid-reflux for 40-plus years. It had become so bad that she was on three medications just to deal with the symptoms. After much training and coaxing, I finally got across to her how to totally get off wheat. Not at all to my surprise, after being wheat free for a few weeks, she lost weight and her acid reflux was GONE!

But she had been addicted to wheat for so long, she relapsed, and the reflux fire soon returned. Wheat must be akin to heroin with some people. Even though they know it's very bad for them, they can't help themselves.

Onschedule said:

Re-exposure often leads to diarrhea for me, or such a heavy feeling of tiredness that all I can do is lay down and pass out. A local pizzeria makes a darn good pie, but since I started practicing wheat-avoidance, I can't keep my eyes open after eating there. I can't say for sure that it's the wheat causing it, but definitely something in the crust. Diarrhea, on the other hand, is definitely triggered by the wheat for me.

My mom complained of gastric reflux for years, but never filled the prescriptions that her doctors would give her. I suggested wheat-avoidance- gastric reflux disappeared within 3 days and hasn't returned (has been 6 months now). I've already commented elsewhere on this blog about how much weight and bloating she has lost...

Steve said:

Interesting that I should sit down, turn on my computer and find your poll. Having gone several weeks, maybe months, avoiding gluten, I took my daughter and her boyfriend out to eat because my wife has been working late at the office lately. Although I was thinking I would just eat my steak and chicken, I succumbed to the temptation of eating about a dozen greasy, breaded shrimp that my daughter and her boyfriend ordered. It's 1:39am and I still do not feel sleepy. My left nostril is completely blocked, my stomach feels bloated, really, really full and I've been burping. In your poll I checked sinus problems but could have chose gastrointestinal or nervous problems just as well.

A few weeks ago my daughter brought home a pizza and, once again, despite my knowing that I shouldn't, I ate a couple of pieces. I was sick for two days. The pain in what I think was my transverse colon was so bad I thought I might have to go to ther emergency room. Before I ate the pizza I had never gone grain-free that long before. I did this after reading Robb Wolf's book.

I AM CONVINCED. No more wheat for me! Please, Lord, give me strength.

LV said:

What don't I experience! I typically avoid wheat (and gluten for that matter) as I'm pretty sure it makes me sick, but when I slip (or someone else slips me some) I end up with massive amounts of joint swelling and tenderness, diarhea, cramping, gas, bloating and brain fog. I'm absolutely miserable. Just that alone is enough to keep me off gluten. I have RA, so if I have repeated exposures I'll have a flare which SUCKS!

A carpenter is only as good as his tools

4. février 2011 William Davis (18)

A carpenter wouldn't build a house using just his bare hands. You shouldn't stumble your way through nutritional blunders without the proper tools to guide you.

Best tool to lose weight:

Best tool to cure diabetes:

Best tool to reduce small LDL particles:

Best tool for anti-aging:

Observing blood sugar excursions after eating is proving to be among the most powerful tools I have come across.

The perfect Frankengrain

4. février 2011 William Davis (25)

Pretend I'm a mad food scientist. I'd like to create a food that:

1) Wreaks gastrointestinal havoc and cause intractable diarrhea, cramps, and anemia.
2) Kills some people who consume it after a long, painful course of illness.
3) Damages the brain and nervous system such that some people wet their pants, lose balance, and lose the ability to feel their feet and legs.
4) Brings out the mania of bipolar illness.
5) Amplifies auditory hallucinations in people with paranoid schizophrenia.
6) Makes people diabetic by increasing blood sugars.
7) Worsens arthritis, such as osteoarthritis and rheumatoid arthritis.
8) Triggers addictive eating behavior.
9) Punishes you with a withdrawal process if you try to remove it from your diet.

I will develop a strain that is exceptionally hardy and tolerates diverse conditions so that it can grow in just about any climate. It should also be an exceptionally high yield crop, so that I can sell it cheaply to the masses.

Now, if my evil scheme goes as planned, I will then persuade the USDA that not only is my food harmless, but it is good for health. If they really take the bait, they might even endorse it, create a diet program around it.

Dag nabit! Such a plan has already been implemented. Another evil food scientist already beat me to the punch. The food is called wheat.

Diabetes: A study in aging

3. février 2011 William Davis (0)

Diabetics experience long-term health difficulties, including atherosclerosis/heart attacks, peripheral vascular disease, hypertension, cataracts, kidney disease, neuropathies, male erectile dysfunction, osteoarthritis, and colorectal cancer. They also die, on average, 10 years earlier than non-diabetics.

In effect, diabetics compress their lives into a shorter period of time. They experience all the "complications" of aging at a younger age. People without diabetes, of course, can develop atherosclerosis, cataracts, kidney disease, etc., but they tend to do so later in life compared to diabetics.

One index of the rate of aging (but not chronologic age itself) is hemoglobin A1c, or HbA1c, a "moving average" of glycated hemoglobin, i.e., glucose-modified hemoglobin. Blood glucose glycates hemoglobin linearly and irreversibly; measuring HbA1c thereby provides an index of the last 60 or so days average blood glucose.

To put HbA1c values into perspective:

Average HbA1c of hunter-gatherers: 4.5%
Average HbA1c for Americans: 5.6%
American Diabetes Association definition of diabetes: 6.5% or greater
American Diabetes Association definition of adequate control of diabetes: 7.0% or less

Why do diabetics age faster? There are likely several reasons. One important reason is glycation, as indexed by HbA1c. Glycated proteins in the lens of the eye causes cataracts. Glycated proteins in cartilage leads to arthritis. Glycated LDL particles (apo B) leads to atherosclerosis. Glycated nerve cells causes neuropathy. And so on.

If glycation underlies many of the phenomena of aging, then we might surmise that:

1) The less you glycate, the slower you age.
2) The more you glycate, the faster you age.

Therefore, the higher the HbA1c, the faster you are aging.

What foods increase HbA1c? Carbohydrates. That bowl of slow-cooked, stone ground oatmeal? A one-hour after-eating blood sugar of 170 mg/dl is common. Your doctor says that's okay because it's below 200 mg/dl and you don't "need" medication yet.

Why do the Japanese have less heart disease?

24. April 2011 William Davis (49)

We should look to the Japanese to teach us a few lessons about preventing heart disease. A Japanese male has only 65% of the risk of an American male (despite 40% of Japanese men being smokers), while a Japanese woman has 80% less risk than an American woman. While the U.S. is near the top of the list of nations with highest cardiovascular risk, Japan is the lowest.

What are they doing right?

There is no one explanation, but several. Genetics probably does not play a substantial role, by the way, as demonstrated by observations of Japanese people who emigrate to Western cultures. People of Japanese heritage living in Hawaii, for instance, develop the same cardiovascular risk as non-Japanese living in Hawaii. They also develop obesity and diabetes.

Among the factors that likely contribute to reduced risk in Japanese people:

--A style of eating that does not include a lot of sweet foods. No breakfast cereal or donuts for breakfast, for instance, but miso soup with tofu, fish, green onions, and daikon (as takuan, or pickled radish).
--Seaweed--It's probably a combination of the green phytonutrients and iodine. Typical daily iodine intake is in the neighborhood of 5000 mcg per day from nori, kombu, wakame, and other seaweed forms. (The average American obtains 125 mcg per day of iodine from diet.)
--Seafood--Fish in many forms not seen in the U.S. are popular.
--Green tea--Consumption of green tea has been confidently linked to reduced cardiovascular risk, probably via visceral fat-reducing, anti-oxidative, and anti-inflammatory effects. Although tea in Japan is often the less flavonoid-rich oolong tea, softer benefits from this form are likely.
--Soy--Tofu, miso, and soy sauce are staples. It's not clear to me whether soy is intrinsically beneficial or whether it is beneficial because it serves to replace unhealthy alternatives. (Genetic modification may change this effect.)
--Reduced exposure to cooked animal products (except seafood). This is not a saturated fat issue, but probably an advanced glycation end-product/lipoxidation issue that result from cooking.
--The lack of a "eat more healthy whole grain" mentality, the advice that has plunged the entire U.S. into the depths of a diabetes and obesity crisis (along with high-fructose corn syrup and sugar). Noodles like udon and ramen do have a place in their diet, as do some dessert foods. But the overall wheat exposure is less--no bagels, sandwiches, and breakfast cereals.
--Less overweight and obesity--The above eating style leads to less weight gain.

Japanese foods have a unique taste, consistency, and mouth-feel that go well with saltiness, thus the downside of their diet: salt consumption. On a broad scale, high salt consumption has been associated with hypertension and gastric cancer. But the tradeoff has, on the whole, been a favorable one.

One study trying to find some answers:

Dietary patterns and cardiovascular disease mortality in Japan: a prospective cohort study.

Shimazu T, Kuriyama S, Hozawa A et al.
Division of Epidemiology, Department of Public Health and Forensic Medicine, Tohoku University Graduate School of Medicine, Japan.

We prospectively assessed the association between dietary patterns among the Japanese and CVD mortality. Dietary information was collected from 40 547 Japanese men and women aged 40-79 years without a history of diabetes, stroke, myocardial infarction or cancer at the baseline in 1994.
During 7 years of follow-up, 801 participants died of CVD.

Factor analysis (principal component) based on a validated food frequency questionnaire identified three dietary patterns: (i) a Japanese dietary pattern highly correlated with soybean products, fish, seaweeds, vegetables, fruits and green tea, (ii) an 'animal food' dietary pattern and (iii) a high-dairy, high-fruit-and-vegetable, low-alcohol (DFA) dietary pattern. The Japanese dietary pattern was related to high sodium intake and high prevalence of hypertension. After adjustment for potential confounders, the Japanese dietary pattern score was associated with a lower risk of CVD mortality (hazard ratio of the highest quartile vs the lowest, 0.73; 95% confidence interval: 0.59-0.90; P for trend = 0.003). The 'animal food' dietary pattern was associated with an increased risk of CVD, but the DFA dietary pattern was not.

The Japanese dietary pattern was associated with a decreased risk of CVD mortality, despite its relation to sodium intake and hypertension.

Niacin: What forms are safe?

20. April 2011 William Davis (52)

Niacin, or vitamin B3, remains a confusing issue for many people. It shouldn't be.

It doesn't help that most physicians and many pharmacists also do not understand the basic issues surrounding niacin. The only reason why there is any level of prevailing knowledge about niacin is that Kos Pharmaceuticals managed to "pharmaceuticalize" a niacin preparation, prescription Niaspan, that provided the revenue to fund professional "education."

Niacin can be helpful to increase HDL, reduce small LDL particles and shift them towards the more benign large particles, reduce triglycerides, and reduce lipoprotein(a).

So here's a brief description of the various forms that you will find niacin:

Immediate-release niacin--Also called crystalline niacin or just niacin. This is the original niacin that releases within minutes of ingestion. Because it releases rapidly, it triggers the most intense "hot flush." While this form of niacin works wonderfully well, is the safest, and is dirt cheap, the majority of people are simply unable to tolerate the intense flush. It also works best taken twice a day, generating two intolerable flushes per day.

Slow-release niacin--These preparations were popular in the 1980s, since the slow 12 to 24 hour pattern of release minimized the annoying hot flush. But, with prolonged use, it also became apparent that an unnaceptable frequency of liver toxicity developed. Unfortunately, this means that any niacin preparation that trickles niacin out over an extended period, including many of the slow-release preparations now sold in health food stores and pharmacies, have potential for liver toxicity. These preparations should be avoided.

6-hour release niacin--Releasing niacin more slowly than immediate-release niacin but more rapidly than slow-release niacin, 6-hour release (or what the Niaspan people call "extended-release" niacin) is nearly as effective as immediate-release niacin with approximately the same low potential for liver toxicity. It is far less liver toxic than slow-release niacin. 6-hour release niacin therefore offers the best balance between effectiveness and safety. Preparations that show this pattern of release include Niaspan ($180 per month), the poorly-named Sloniacin (about $8 per month), and Enduracin (about $7 per month) for 1000 mg per day. (Some Track Your Plaque Members have also determined that several other over-the-counter preparations have been demonstrated to share a similar pattern of release.)

Then there are the scam products that have no useful effect at all:

Flush-free or no-flush niacin--Inositol hexaniacinate, or 6 niacin molecules bound to the sugar, inositol, has no effect in humans, at least not with the dozen or so preparations that I've seen used. Nor are there any data to document the effectiveness of flush-free niacin. It's also more expensive.

Nicotinamide--This niacin derivative likewise has no effect on the usual targets for niacin treatment.

While I used to prescribe Niaspan, the ridiculous pricing and aggressive marketing really turned me off. I now advise my patients and our online followers to use only Sloniacin or Enduracin, unless you can tolerate immediate-release niacin.

Introduction to the New Track Your Plaque book, version 2.0

18. April 2011 William Davis (0)

Out with the old,

in with the new

“I believe that you are suffering from what is called a fatty degeneration of the heart.”

Dr. Tertius Lydgate to Mr. Casaubon on making a diagnosis with the new medical device, the stethoscope.

George Elliot

Middlemarch, 1871

Old notions in medicine have a peculiar way of lingering.

In 1882, Dr. Robert Koch discovered the tubercle bacillus in tissues of people with “consumption.” By connecting a bacterium with the disease, he usurped the long held notion that tuberculosis was a degenerative disease caused by lack of fresh air. But, for decades after Dr. Koch’s revelation, the “bad air” belief persisted. Surgical collapse of the lung, a painful and barbaric treatment for tuberculosis, persisted well into the 1960s, years after effective antibiotics were discovered in 1947.

The medical community of the 19^th century viewed mental illness as the hereditary end-product of ancestral nervousness, alcoholism, prostitution and criminal behavior, a bias that remained widespread well into the mid-20^th century. Nazi physicians invoked the theory of heritable “mental degeneration” to justify wholesale extermination of schizophrenics. Electro-convulsive therapy (ECT, or “electroshock therapy”) was widely applied to treat schizophrenia, depression, homosexuality, and criminal behavior for over 30 years, gradually abandoned (at least in its original form) after years of abusive application to subdue patients, demonized in the 1975 movie, “One Flew Over the Cuckoo’s Nest,” depicting the author’s real-life experience with ECT.

Long after a theory or practice has been discredited, it can persist, refusing to die. The new and improved may not be adopted into mainstream practice for years, even decades.

Back to the 21^st century: What if you realized that, by quirks of human nature and the uneven adoption of health information, your doctor practiced medicine appropriate for 1985? 1975?

While digital information nowadays is transmitted at the speed of light, disseminating as fast as it takes the next juicy tidbit to be “virally” reproduced via social networking websites, it’s the human factor that still operates with the inertia of human behavior. Habits and attitudes slow the adoption of new information in time measured not in seconds, but in years or decades.

A century ago, 20 years were required for the new technology of blood pressure measurement to be adopted after its introduction in the U.S. in 1910, since physicians were long comfortable with the practice of “pulse palpation” (feeling the pulse). (The arcane language of pulse palpation persists to this day, terms like “pulsus parvus et tardus,” the slow rising pulse of a stiff aortic valve; and the "water-hammer" pulse of a leaking aortic valve.)

The discovery of new, health-changing information today in the 21^st century disseminates through the ranks of modern healthcare providers at much the same pace as measuring blood pressure did in the early 20^th century.

It’s also tempting to paint American medicine as a fiefdom intent on maintaining exclusive rein over health information. Look back over the hierarchical relationship of medicine over nursing in the past century: When blood pressure measurement was adopted on a broad scale in the 1930s, it was practiced only by physicians, since nurses were deemed incapable. (Modern-day nurses should surely have a hearty laugh over this.) Stethoscopes, around even longer than blood pressure cuffs, weren’t permitted to fall into the hands of nurses until the 1960s, since the medical community feared that nurses might command too much control over patient care. Even after nurses were permitted to have their own stethoscopes, great pains were taken to be certain the nurses’ version was readily distinguishable from the “real” tool wielded by physicians; nurses’ stethoscopes were therefore labeled “nurse-o-scopes,” or “assistoscopes,” and were required to be smaller and flimsier.

Old and ineffective doesn’t always give way to new and better at once; it is slowed by habit as well as an unwillingness to relinquish control.

Somehow technology marches on. But it does so unevenly, sweeping some along in its first wave, others in its wake, some never at all.

Just as effective antibiotics to cure tuberculosis were available for 20 years while surgeons continued to remove patients’ lungs, so better solutions to heart disease are already available but not yet employed by your neighborhood physician. The primary care physician may have heard about some of the newest means to prevent heart disease, but is too overwhelmed with the day-to-day of sore throats, diarrhea, and rashes. Cardiologists, intent on inserting the next best stent or defibrillator, have little but passing interest in strategies that might halt or reverse the heart disease that can be “managed,” no matter how imperfectly, with procedural solutions like angioplasty and bypass surgery. We should bear these flawed human tendencies in mind as we explore the world of heart disease prevention.

We need look no farther than the front page of the newspaper to find evidence of the failure of present-day heart disease detection and management. Over the past several years, headlines have carried the likes of Tim Russert, Bill Clinton, Larry King, Dick Cheney, David Letterman, Tommy Lasorda, Ed Bradley, Mike Ditka, Walter Cronkite, Alberto Salazar, all heart disease sufferers. Some, like talk show host David Letterman, survived their brush with heart catastrophe and underwent successful bypass surgery. Others, like marathoners Fixx and Salazar, raised none of the conventional red flags for heart disease. All received standard, “modern” medical care . . . all the way up to their heart attack, bypass surgery, or untimely death.

Like the sphygnomanometer (blood pressure) cuffs of 1910, Track Your Plaque represents an example of the new. But, unlike the simple practice of taking blood pressure in the early 20^th century, Track Your Plaque represents an entirely new way to look at coronary heart disease: a new way to measure it, a new way to identify its causes, and a new way to seize control over it, often to the point of achieving reversal of the process. It also puts control over much of this process into your hands and away from hospitals, cardiologists, and heart procedures.

I could speak of revealing “secrets,” but that’s not true. In Track Your Plaque, I simply convey information about heart disease that you were likely unaware existed, strategies that doctors fail to discuss. I assemble them into a “package” that, together, create an enormously empowering unique approach to prevent heart disease and heart attack.

Track Your Plaque also challenges the high-tech status quo, practices that occupy exalted places in the enormous cardiovascular healthcare machine that has dominated American healthcare for the past 40 years. I propose that high-tech hospital procedures should join the practice of ECT for homosexuality and insanity¾and become yet another relic of the past.

What are "normal" triglycerides?

Among the most neglected yet enormously helpful values on any standard cholesterol panel is the triglyceride value.

Triglycerides traverse the bloodstream by hitching a ride on water (serum)-soluble lipoproteins, or lipid-carrying proteins. We measure triglycerides as an indirect index of triglyceride-containing lipoproteins.

Triglycerides are a basic currency of energy. While the average American ingests around 300 mg of cholesterol per day, he or she also ingests 60,000-120,000 mg (60-120 grams) of triglycerides, i.e., 200 to 400 times greater amounts, from fat intake. Zero triglycerides in the diet or in the bloodstream is not an option.

But what represents too much triglycerides in the bloodstream? There are several observations to help us make this determination:

1) When fasting triglycerides are 133 mg/dl or greater, 80% of people will show show at least some degree of small LDL particles.

2) When fasting triglycerides are 60 mg/dl or less, most (though not all, since genetic factors enter into the picture) people will show little to no small LDL particles.

3) When fasting triglycerides are 200 mg/dl or greater, small LDL particles will dominate and large LDL particles will be in the minority or be gone entirely.

4) When triglycerides are 88 mg/dl or greater after eating, then risk for heart attack is doubled. Non-fasting triglycerides in the 400+ mg/dl range are associated with 17-fold greater risk for heart attack.

From Austin et al 1990. "Phenotype A" means that large LDL particles dominate; "phenotype B" means that small LDL particles dominate.

Note that conventional "wisdom" (i.e., NCEP ATP-3 guidelines) is that triglycerides of up to 150 mg/dl are okay, a level that virtually guarantees expression of small LDL particles and increased cardiovascular risk.

Based on observations like these, in the Track Your Plaque program we aim for fasting triglycerides of no higher than 60 mg/dl and postprandial (after-meal) triglycerides of no more than 90 mg/dl.

Curiously, while fat intake (i.e., triglyceride intake) plays a role in determining postprandial triglyceride blood levels, it's carbohydrate intake that plays a much larger role. That will be an issue for another day.

1985: The Year of Whole Grains

9. April 2011 William Davis (30)

In 1985, the National Cholesterol Education Panel delivered its Adult Treatment Panel guidelines to Americans, advice to cut cholesterol intake, reduce saturated fat, and increase "healthy whole grains" to reduce the incidence of heart attack and other cardiovascular events.

Per capita wheat consumption increased accordingly. Wheat consumption today is 26 lbs per year greater than in 1970 and now totals 133 lbs per person per year. (Because infants and children are lumped together with adults, average adult consumption is likely greater than 200 lbs per year, or the equivalent of approximately 300 loaves of bread per year.) Another twist: The mid- and late-1980s also marks the widespread adoption of the genetically-altered dwarf variants of wheat to replace standard-height wheat.

In 1985, the Centers for Disease Control also began to track multiple health conditions, including diabetes. Here is the curve for diabetes:

Note that, from 1958 until 1985, the curve was climbing slowly. After 1985, the curve shifted sharply upward. (Not shown is the data point for 2010, an even steeper upward ascent.) Now diabetes is skyrocketing, projected to afflict 1 in 3 adults in the coming decades.

You think there's a relationship?

Have some more

Wheat, via exorphin effects, is an appetite stimulant. Eat a whole wheat bagel or bran muffin, you want another. You also want more of other foods. You also want something to eat every two hours due to widely-swinging insulin-glucose responses: blood sugar high followed by a sharp downturn that triggers a powerful impulse to eat (thus the cravings for a snack at 9 and 11 a.m. after a 7 a.m. breakfast).

If wheat is a stimulant of appetite, then removing it should yield reduced appetite and reduced calorie intake. That is precisely what happens.

When wheat products are removed from the diet--without calorie restriction, without counting fat or carbohydrate grams, no exercise program, no cleansing regimen, no skipping meals . . . nothing--calorie intake drops 350 to 400 calories per day. This calorie figure remains curiously consistent across multiple studies in which wheat was eliminated.

400 calories per day results in 21 lbs lost over 6 months, based just on calories. (3500 calories per pound lost.) That is what happens in wheat elimination diets: 21-26 lbs lost over 6 months.

Wheat is the processed food industry's nicotine, a means of ensuring repeat food purchases. It's also low-cost (subsidized by the U.S. government), high-yield, an ingredient that even has its very own withdrawal syndrome should you miss a "hit."

When MIGHT statins be helpful?

7. April 2011 William Davis (17)

I spend a lot of my day bashing statin drugs and helping people get rid of them.

But are there instances in which statin drugs do indeed provide real advantage? If someone follows the diet I've articulated in these posts and in the Track Your Plaque program, supplements omega-3 fatty acids and vitamin D, normalizes thyroid measures, and identifies and corrects hidden genetic sources of cardiovascular risk (e.g., Lp(a)), then are there any people who obtain incremental benefit from use of a statin drug?

I believe there are some groups of people who do indeed do better with statin drugs. These include:

Apoprotein E4 homozygotes

Apoprotein E2 homozygotes

Familial combined hyperlipidemia (apoprotein B overproduction and/or defective degradation)

Cholesteryl ester transfer protein homozygotes (though occasionally manageable strictly with diet)

Familial heterozygous hypercholesterolemia, familial homozygous hypercholesterolemia

Other rare variants, e.g., apo B and C variants

The vast majority of people now taking statin drugs do NOT have the above genetic diagnoses. The majority either have increased LDL from the absurd "cut your fat, eat more healthy whole grains" diet that introduces grotesque distortions into metabolism (like skyrocketing apo B/VLDL and small LDL particles) or have misleading calculated LDL cholesterol values (since conventional LDL is calculated, not measured).

As time passes, we are witnessing more and more people slow, stop, or reverse coronary plaque using no statin drugs.

Like antibiotics and other drugs, there may be an appropriate time and situation in which they are helpful, but not for every sneeze, runny nose, or chill. Same with statin drugs: There may be an occasional person who, for genetically-determined reasons, is unable to, for example, clear postprandial (after-eating) lipoproteins from the bloodstream and thereby develops coronary atherosclerotic plaque and heart attack at age 40. But these people are the exception.

Advanced topics in nutrition

5. April 2011 William Davis (0)

Nutrition in the modern world has become an increasingly problematic topic. From genetic modification to commercialized methods of mass production, we are having to navigate all manner of complex issues in food choices, particularly if ideal health, including maximal control over coronary plaque, is among our goals.

We will therefore be releasing a series of discussions on the Track Your Plaque website in the coming months, a series I call "Track Your Plaque Advanced Topics in Nutrition." These will be, as the series title suggests, discussions for anyone interested in more than the "eat a balanced diet" nonsense that issues from "official" sources. Among the topics to be covered:

1)Advanced Glycation End-products--both endogenous and exogenous, including peripheral issues like lipoxidation and acrylamides.

2)Dietary influences on LDL oxidation--including the concept of "glycoxidation." Protection from oxidative phenomena is not just about taking antioxidants.

3) Foods you MUST eat--We've talked a lot about foods that you shouldn't eat. How about foods you should eat?

The New Track Your Plaque Guide now available

4. April 2011 William Davis (5)

The New Track Your Plaque Guide is now available!

The Track Your Plaque program has evolved over its 8 year history. While the original Track Your Plaque book reflected the program details that got the program started back in 2003-2004, plenty has changed.

This new version of the book, what I call the program Guide, represents version 2.0 of Track Your Plaque and includes:

--Updated lipoprotein treatment strategies--including new and expanded treatment choices for small LDL and lipoprotein(a).

--An entire chapter on vitamin D and its crucial role in cardiovascular health and plaque control.

--A new and expanded diet--All the reasons why the New Track Your Plaque Diet can achieve spectacular improvement in lipids/lipoproteins, reversal of insulin resistance/pre-diabetes/diabetes, weight loss, reduction in blood pressure, etc. are discussed in considerable detail. The diet is crafted to achieve maximum control over both metabolic responses and coronary plaque.

--An entire chapter on the role of omega-3 fatty acids is included.

--A detailed discussion on the role of iodine and thyroid health--One of the newest additions to the Track Your Plaque menu of strategies is to achieve and maintain ideal thyroid health. This tips the scales in your favor for improved control over lipids/lipoproteins, weight, blood sugar, and coronary plaque.

The new guide, as well as our new Member kits that include the new Track Your Plaque Recipe Book, At-Home Lab Test kits, and nutritional supplements, are all available in the Track Your Plaque Marketplace.

Don't wet yourself

3. April 2011 William Davis (13)

While there is more to wheat's adverse effects on human health than celiac disease, studying celiac disease provides important insights into why and how wheat--the gluten component of wheat, in this case--is so destructive to human health.

Modern wheat, in particular, is capable of causing "celiac disease" without intestinal symptoms---no cramping or diarrhea--but instead shows itself as brain injury (ataxia, dementia), peripheral nervous system damage (peripheral neuropathy), joint and muscle inflammation (rheumatoid arthritis, polymyalgia rheumatica and others), and gastrointestinal cancers.

One neurological manifestation of wheat's effect on the human brain is a condition called cerebellar ataxia. This is a condition that can affect adults (average age 48 years) and children and consists of incoordination, falls, and incontinence.

Because brain tissue has limited capacity for healing and regeneration, symptoms of cerebellar ataxia usually improve slowly and modestly with meticulous elimination of wheat and other gluten sources.

Such observations are relevant even to people without celiac disease. Celiac disease sufferers are more susceptible to such extra-intestinal phenomena, but it can also happen in people without positive celiac antibodies.

Some references:

Neurological symptoms in patients with biopsy proven celiac disease

A total of 72 patients with biopsy proven celiac disease (CD) (mean age 51 +/- 15 years, mean disease duration 8 +/- 11 years) were recruited through advertisements. All participants adhered to a gluten-free diet. Patients were interviewed following a standard questionnaire and examined clinically for neurological symptoms. Medical history revealed neurological disorders such as migraine (28%), carpal tunnel syndrome (20%), vestibular dysfunction (8%), seizures (6%), and myelitis (3%). Interestingly, 35% of patients with CD reported of a history of psychiatric disease including depression, personality changes, or even psychosis. Physical examination yielded stance and gait problems in about one third of patients that could be attributed to afferent ataxia in 26%, vestibular dysfunction in 6%, and cerebellar ataxia in 6%. Other motor features such as basal ganglia symptoms, pyramidal tract signs, tics, and myoclonus were infrequent. 35% of patients with CD showed deep sensory loss and reduced ankle reflexes in 14%. Gait disturbances in CD do not only result from cerebellar ataxia but also from proprioceptive or vestibular impairment.

Gluten ataxia in perspective: epidemiology, genetic susceptibility and clinical characteristics

Two hundred and twenty-four patients with various causes of ataxia from North Trent (59 familial and/or positive testing for spinocerebellar ataxias 1, 2, 3, 6 and 7, and Friedreich's ataxia, 132 sporadic idiopathic and 33 clinically probable cerebellar variant of multiple system atrophy MSA-C) and 44 patients with sporadic idiopathic ataxia from The Institute of Neurology, London, were screened for the presence of antigliadin antibodies. A total of 1200 volunteers were screened as normal controls. The prevalence of antigliadin antibodies in the familial group was eight out of 59 (14%), 54 out of 132 (41%) in the sporadic idiopathic group, five out of 33 (15%) in the MSA-C group and 149 out of 1200 (12%) in the normal controls. The prevalence in the sporadic idiopathic group from London was 14 out of 44 (32%). The difference in prevalence between the idiopathic sporadic groups and the other groups was highly significant (P < 0.0001 and P < 0.003, respectively). The clinical characteristics of 68 patients with gluten ataxia were as follows: the mean age at onset of the ataxia was 48 years (range 14-81 years) with a mean duration of the ataxia of 9.7 years (range 1-40 years). Ocular signs were observed in 84% and dysarthria in 66%. Upper limb ataxia was evident in 75%, lower limb ataxia in 90% and gait ataxia in 100% of patients. Gastrointestinal symptoms were present in only 13%. MRI revealed atrophy of the cerebellum in 79% and white matter hyperintensities in 19%. Forty-five percent of patients had neurophysiological evidence of a sensorimotor axonal neuropathy. Gluten-sensitive enteropathy was found in 24%. HLA DQ2 was present in 72% of patients. Gluten ataxia is therefore the single most common cause of sporadic idiopathic ataxia.
