Calling all super-duper weight losers!

9. July 2011 William Davis (12)

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

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

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

Lp(a): Be patient with fish oil

8. July 2011 William Davis (35)

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

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

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

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

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

Baby your pancreas

1. July 2011 William Davis (35)

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

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

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

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

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

Bread equals sugar

22. June 2011 William Davis (36)

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

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

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

Gluten-free carbohydrate mania

18. June 2011 William Davis (14)

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

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

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

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

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

Gluten-free is going DOWN

16. June 2011 William Davis (18)

The majority of gluten-free foods are junk foods.

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

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

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

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

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

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

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

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

Medicine ain't what it used to be

15. June 2011 William Davis (0)

The practice of medicine ain't what it used to be.

For instance:

White coats are out-of-date--Not only do they serve as filthy reservoirs of microorganisms (since they hang unwashed after repeated use week after week), they only serve to distance the practitioner from the patient, an outdated notion that should join electroshock therapy to treat homosexuality and other "disorders" in the museum of outdated medical practices.

Normal cholesterol panel . . . no heart disease?

15. June 2011 William Davis (19)

I often hear this comment: "I have a normal cholesterol panel. So I have low risk for heart disease, right?"

While there's a germ of truth in the statement, there are many exceptions. Having "normal" cholesterol values is far from a guarantee that you won't drop over at your daughter's wedding or find yourself lying on a gurney at your nearest profit-center-for-health, aka hospital, heading for the cath lab.

Statistically, large populations do indeed show fewer heart attacks at the lower end of the curve for low total and LDL cholesterol and the higher end of HDL. But that's on a population basis. When applied to a specific individual, population observations can fall apart. Heart attack can occur at the low risk end of the curve; no heart attack can occur at the high risk end of the curve.

First of all, to me a "normal" lipid panel is not adhering to the lax notion of "normal" specified in the lab's "reference range" drawn from population observations. Most labs, for instance, specify that an HDL cholesterol of 40 mg/dl or more and triglycerides of 150 mg/dl or less are in the normal ranges. However, heart disease can readily occur with normal values of, say, an HDL of 48 mg/dl and triglycerides of 125 mg/dl, both of which allow substantial small oxidation-prone LDL particles to develop. So "normal" may not be ideal or desirable. Look at any study comparing people with heart disease vs. those without, for instance: Typical HDLs in people with heart attacks are around 46 mg/dl, while HDLs in people without heart attacks typically average 48 mg/dl--there is nearly perfect overlap in the distribution curves.

There are also causes for heart disease that are not revealed by the lipid values. Lipoprotein(a), or Lp(a), is among the most important exceptions: You can have a heart attack, stroke, three stents or bypass surgery at age 40 even with spectacular lipid values if you have this genetically-determined condition. And it's not rare, since 11% of the population express it. How about people with the apo E2 genetic variation? These people tend to have normal fasting cholesterol values (if they have only one copy of E2, not two) but have extravagant abnormalities after they eat that contribute to risk. You won't know this from a standard cholesterol panel.

Vitamin D deficiency can be suggested by low HDL and omega-3 fatty acid deficiency suggested by higher triglycerides, but deficiencies of both can exist in severe degrees even with reasonably favorable ranges for both lipid values. Despite the recent inane comments by the Institute of Medicine committee, from what I've witnessed from replacing vitamin D to achieve serum 25-hydroxy vitamin D levels of 60-70 ng/ml, vitamin D deficiency is among the most powerful and correctable causes of heart disease I've ever seen. And, while greater quantities of omega-3 fatty acids from fish oil are associated with lower triglycerides, they are even better at reducing postprandial phenomena, i.e., the after-eating flood of lipoproteins like VLDL and chylomicron remnants, that underlie formation of much atherosclerotic plaque--but not revealed by fasting lipids.

I view standard cholesterol panels as the 1963 version of heart disease prediction. We've come a long way since then and we now have far better tools for prediction of heart attack. Yet the majority of physicians and the public still follow the outdated notion that a cholesterol panel is sufficient to predict your heart's future. Nostalgic, quaint perhaps, but as outdated as transistor radios and prime time acts on the Ed Sullivan show.

Idiot farm

11. June 2011 William Davis (10)

The notion of genetic modification of foods and livestock is a contentious issue. The purposeful insertion or deletion of a gene into a plant or animal's genome to yield specific traits, such as herbicide resistance, nutritional composition, or size, prompted the Codex Alimentarius Commission, an international effort to regulate the safety of foods, to issue guidelines concerning genetically-modified foods.

The committee is aware of the concept of unintended effects, i.e., effects that were not part of the original gene insertion or deletion design. In their report, last updated in 2009, they state that:

Unintended effects can result from the random insertion of DNA sequences into the plant genome, which may cause disruption or silencing of existing genes, activation of silent genes, or modifications in the expression of existing genes. Unintended effects may also result in the formation of new or changed patterns of metabolites. For example, the expression of enzymes at high levels may give rise to secondary biochemical effects or changes in the regulation of metabolic pathways and/or altered levels of metabolites.

They make the point that food crops generated using techniques without genetic modification are released into the food supply without safety testing:

New varieties of corn, soybean, potatoes and other common food plants are evaluated by breeders for agronomic and phenotypic characteristics, but generally, foods derived from such new plant varieties are not subjected to the rigorous and extensive food safety testing procedures, including studies in animals, that are typical of chemicals, such as food additives or pesticide residues, that may be present in food.

In other words, conventional plant breeding techniques, such as hybridization, backcrossing, and introgression, practices that include crossing parental plants with their progeny over and over again or crossing a plant with an unrelated plant, yield unique plants that are not subject to any regulation. This means that unintended effects that arise are often not identified or tested. Plant geneticists know that, when one plant is crossed with another, approximately 5% of the genes in the offspring are unique to that plant and not present in either parent. It means that offspring may express new characteristics, such as unique gliadin or gluten proteins in wheat, not expressed in either parent and with new immunological potential in consuming humans.

Dr. James Maryanski, the FDA's Biotechnology Coordinator, stated during Congressional testimony in 1999 that:

The new gene splicing techniques are being used to achieve many of the same goals and improvements that plant breeders have sought through conventional methods. Today's techniques are different from their predecessors in two significant ways. First, they can be used with greater precision and allow for more complete characterization and, therefore, greater predictability about the qualities of the new variety. These techniques give scientists the ability to isolate genes and to introduce new traits into foods without simultaneously introducing many other undesirable traits, as may occur with traditional breeding. [Emphasis mine.]

Efforts by the Codex Alimentarius and FDA are meant to control the introduction and specify safety testing procedures for genetically modified foods. But both organizations have publicly stated that there is another larger problem that has not been addressed that predates genetic modification. In other words, conventional methods like hybridization techniques, the crossing of different strains of a crop or crossing two dissimilar plants (e.g., wheat with a wild grass) have been practiced for decades before genetic modification became possible. And it is still going on.

In other words, the potential hazards of hybridization, often taken to extremes, have essentially been ignored. Hybridized plants are introduced into the food supply with no question of human safety. While hybridization can yield what appear to be benign foods, such as the tangelo, a hybrid of tangerines and grapefruit, it can also yield plants containing extensive unintended effects. It means that unique immunological sequences can be generated. It might be a unique gliadin sequence in wheat or a unique lectin sequence in beans. None are tested prior to selling to humans. So the world frets over the potential dangers of genetic modification while, all along, the much larger hazard of hybridization techniques have been--and still are--going on.

Imagine we applied the hybridization techniques applied by plant geneticists to humans, mating an uncle with his niece, then having the uncle mate again with the offspring, repeating it over and over until some trait was fully expressed. Such extensive inbreeding was practiced in the 19th century German village of Dilsberg, what Mark Twain described as "a thriving and diligent idiot factory."

Eat triglycerides

8. June 2011 William Davis (31)

Dietary fats, from olive oil to cocoa butter to beef tallow, are made of triglycerides.

Triglycerides are simply three ("tri-") fatty acids attached to a glycerol backbone. Glycerol is a simple 3-carbon molecule that readily binds fatty acids. Fatty acids, of course, can be saturated, polyunsaturated, and monounsaturated.

Once ingested, the action of the pancreatic enzyme, pancreatic lipase, along with bile acids secreted by the gallbladder, remove triglycerides from glycerol. Triglycerides pass through the intestinal wall and are "repackaged" into large complex triglyceride-rich (about 90% triglycerides) molecules called chylomicrons, which then pass into the lymphatic system, then to the bloodstream. The liver takes up chylomicrons, removes triglycerides which are then repackaged into triglyceride-rich very low-density lipoproteins (VLDL).

So eating triglycerides increases blood levels of triglycerides, repackaged as chylomicrons and VLDL.

Many physicians are frightened of dietary triglycerides, i.e, fats, for fear it will increase blood levels of triglycerides. It's true: Consuming triglycerides does indeed increase blood levels of triglycerides--but only a little bit. Following a fat-rich meal of, say, a 3-egg omelet with 2 tablespoons of olive oil and 2 oz whole milk mozzarella cheese (total 55 grams triglycerides), blood triglycerides will increase modestly. A typical response would be an increase from 60 mg/dl to 80 mg/dl--an increase, but quite small.

Counterintuitively, it's the foods that convert to triglycerides in the liver that send triglycerides up, not 20 mg/dl, but 200, 400, or 1000 mg/dl or more. What foods convert to triglycerides in the liver? Carbohydrates.

After swallowing a piece of multigrain bread, for instance, carbohydrates are released by salivary and gastric amylase, yielding glucose molecules. Glucose is rapidly absorbed through the intestinal tract and into the liver. The liver is magnificently efficient at storing carbohydrate calories by converting them to the body's principal currency of energy, triglycerides, via the process of de novo lipogenesis, the alchemy of converting glucose into triglycerides for storage. The effect is not immediate; it may require many hours for the liver to do its thing, increasing blood triglycerides many hours after the carbohydrate meal.

This explains why people who follow low-fat diets typically have high triglyceride levels--despite limited ingestion of triglycerides. When I cut my calories from fat to 10% or less--a very strict low-fat diet--my triglycerides are 350 mg/dl. When I slash my carbohydrates to 40-50 grams per day but ingest unlimited triglycerides like olive oil, raw nuts, whole milk cheese, fish oil and fish, etc., my triglycerides are 50 mg/dl.

Don't be afraid of triglycerides. But be very careful with the foods that convert to triglycerides: carbohydrates.

Cholesterol follies

11. January 2008 William Davis (5)

Rudy is a 59-year old man. He's had three heart catheterizations, two of which resulted in stent implantations. Obviously, Rudy should be the beneciary of a prevention program.

His basic cholesterol values:

Total cholesterol 164 mg/dl--pretty good, it seems.

LDL cholesterol 111 mg/dl--Wow! Not too bad.

HDL cholesterol 23 mg/dl--Uh oh, that's not too good.

Triglycerides 148 mg/dl--By national (NCEP ATP-III) guidelines, triglycerides of 150 mg/dl and below fall within the desirable range.

So we're left with an apparently isolated low HDL cholesterol, nothing more. On the surface, it doesn't seem all that bad.

Of course, we need to keep in mind that this pattern landed Rudy in the hospital on several occasions and prompted several procedures.

Should we rely on these results? How about Rudy's lipoproteins?

Here they are (NMR; Liposcience):

LDL particle number 2139 nmol/l--Representing an effective LDL of 213--over 100 mg higher than the standard value (above) suggests.

Small LDL particles 2139 nmol/l--In other words, 100% of all Rudy's LDL particles are small. (Thus, weight-based measures of LDL cholesterol fail to tell us that he has too many small particles.)

Large HDL 0 (zero) mg/dl--Rudy has virtually no functional HDL particles.

If we had relied only on Rudy's standard cholesterol values, we would have focused on raising HDL. However, lipoprotein analysis uncovered a smorgasbord of additional severe patterns. The high LDL particle number comprised 100% of small particles is especially concerning.

Truly, conventional cholesterol testing is a fool's game, one that time and again fails to fully uncover or predict risk for heart disease. One look at Rudy's lipoproteins and it becomes immediately obvious: This man is at high risk for heart disease and the causes are clear.

Of course, many physicians and insurance companies argue that the added information provided by this portion of the lipoprotein test added around $70 more to the expense.

When you see results like this, is there even a choice?

Equal calories, different effects

9. January 2008 William Davis (15)

A great study was just published in the Journal of the American College of Cardiology:

Metabolic effects of weight loss on a very-low-carbohydrate diet compared with an isocaloric high-carbohydrate diet in abdominally obese subjects.

88 obese adults with metabolic syndrome were placed on either of two diets:

1) A very low-carbohydrate, high-fat diet (VLCHF): 4% calories from carbohydrates (truly low-carb); 35% protein; 61% fat, of which 20% were saturated. In the first 8 weeks, carbohydrate intake was severely limited to <20 grams per day, then <40 grams per day thereafter.

2) A high-carbohydrate, low-fat diet (HCLF): 46% calories from carbohydrates; 24% protein; 30% total fat, of which <8% were saturated.

Both diets were equal in calories (around 1400 calories per day--rather restrictive) and participants were maintained on the program for six months.

At the end of the six month period, participants on the VLCHF diet lost 26.4 lb, those on the HCLF diet 22.2 lbs (though the difference did not reach statistical significance). Thus, both approaches were spectacularly successful at weight loss.

Surprisingly, blood pressure, blood sugar, insulin and insulin sensitivity (a measure called HOMA) were all improved with both diets equally. Thus, these measures seemed to respond more to weight loss and less to the food composition.

Lipids differed between the two diets, however:

VLCHF:
Total cholesterol: initial 208.4 mg/dl final 207.7 mg/dl

LDL: initial 125 mg/dl final 123 mg/dl

HDL: initial 55 mg/dl final 64.5 mg/dl

Triglycerides: initial 144 mg/dl final 74 mg/dl

Apoprotein B: initial 98 mg/dl final 96 mg/dl

HCLF
Total cholesterol: initial 208.4 mg/dl final 187.5 mg/dl

LDL: initial 126 mg/dl final 108 mg/dl

HDL: initial 51 mg/dl final 54.5 mg/dl

Triglycerides: initial 157.6 mg/dl final 111 mg/dl

Apoprotein B: initial 100 mg/dl final 95 mg/dl

Some interesting differences became apparent:
--The VLCHF diet more effectively reduced triglycerides and raised HDL.
--The HCLF diet more effectively reduced total and LDL.
--There was no difference in Apo B (no statistical difference).

The investigators also made the observation that individual responsiveness to the diets differed substantially. They concluded that both diets appeared to exert no adverse effect on any of the parameters measured, both were approximately equally effective in weight loss with slight advantage with the carbohydrate restricted diet, and that lipid effects were indeed somewhat different.

What lessons can we learn from this study? I would propose/extrapolate several:

When calories are severely restricted, the composition of diet may be less important. However, when calories are not so severely restricted, then composition may assume a larger role. When calories are unrestricted, I would propose that the carbohydrate restriction approach may yield larger effects on weight loss and on lipids when compared to a low-fat diet.

The changes in total cholesterol are virtually meaningless. Part of the reason that it didn't drop with the VLCHF diet is that HDL cholesterol increased. In other words, total cholesterol = LDL + HDL + trig/5. A rise in HDL raises total cholesterol.

Despite no change in Apo B, if NMR lipoprotein analysis had been performed (or other assessment of LDL particle size made), then there would almost certainly have seen a dramatic shift from undesirable small LDL to less harmful large LDL particles on the VLCHF diet, less change on the HCLF diet.

The lack of restriction of saturated fat in the VLCHF that failed to yield adverse effects is interesting. It would be conssistent with the re-analysis of saturated fat as not-the-villain-we thought-it-was put forward by people like Gary Taubes (Good Calories, Bad Calories).

In the Track Your Plaque experience, small LDL is among the most important measures of all for coronary plaque reversal and control. Unfortunately, although this study was well designed and does add to the developing scientific exploration of diet, it doesn't add to our insight into small LDL effects. But if I had to make a choice, I'd choose the low-carbohydrate, high-fat approach for overall benefit.

Is skinny necessary for reversal?

6. January 2008 William Davis (19)

Nothing we do in the Track Your Plaque program guarantees that coronary atherosclerotic plaque or your heart scan score is reduced or reversed.

But everything we do weighs the odds in your favor of successfully achieving reversal: correction of lipoprotein patterns, uncovering hidden patterns like Lp(a), vitamin D, being optimistic--it all tips the scales in your favor.

But how necessary is it to be skinny, meaning somewhere near your ideal weight?

It is important, but not as important as it used to be. Let me explain.

I used to tell people that plaque would not regress unless ideal weight was achieved and all the parameters of abdominal obesity and metabolic syndrome were corrected. This includes blood pressure, blood sugar, low HDL, small LDL, high triglycerides, and high c-reactive protein. Curiously, though, as we've gotten better and better at reducing coronary calcium scores, I've been finding that complete correction of all parameters, including achieving ideal weight, don't seem to be as necessary to achieve plaque reversal.

I almost hate to say this, but I've even witnessed significant drops in heart scan scores in people with body mass indexes (BMI) of 30--obese.

The necessary change doesn't seem to be weight, per se, but the consequences of weight. In other words, if you remain overweight, but blood sugar, HDL, small LDL, etc. have shown substantial improvement, then reversal is still achievable.

Then is it okay to be fat or overweight?

Reducing weight to ideal weight does indeed tip the scales in your favor, since it represents an observable, perceptible measure of all associated patterns. Dropping weight can also minimize the need for efforts to correct the consequences of overweight--you might need less niacin, fish oil, exercise, blood pressure medication, etc. to succeed at plaque reversal. Achieving ideal weight may also provide benefits like reduced risk of cancers and degenerative diseases of the hips and knees. But, to my recent surprise over the last two years, achieving ideal weight is not an absolute requirement to achieve reversal.

This is contrary to what some others say. For instance, in an upcoming interview with Dr. Joel Fuhrman on the Track Your Plaque website, Dr. Fuhrman argues that 10% body fat for males, 22% body fat for females, accelerates plaque and symptom reversal. Dr. Fuhrman is author of Fasting and Eating for Health, Eat to Live, and a new upcoming 2-part book, Eat for Health, and proponent of high-nutrient vegetarian diets and fasting. Dr. Fuhrman has been helpful in teaching us some important lessons on how to apply periodic fasting to accelerate plaque reversal.

So, which is it, fat or skinny?

If given a choice (which everyone has), I'd choose skinny. But, provided all the parameters associated with overweight are corrected, then remaining overweight doesn't necessarily mean that you can't still succeed at plaque reversal.

If you are interested in knowing what your ideal weight is, there are a number of software calculators and tables available, including the HealthCentral.com calculator and the National Heart, Lung, and Blood Institute BMI Calculator.

MESA Study: Track Your Plaque-Lite?

4. January 2008 William Davis (11)

The long-awaited data analyses from the Multi-Ethnic Study of Atherosclerosis (MESA) are finally making it to press.

The MESA Study is an enormously ambitious and important study of 6800 people, 45 to 84 years old, that includes white, black, Hispanic, and Chinese participants from six communities around the U.S. (Forsyth County, NC; Northern Manhattan and the Bronx, NY; Baltimore and Baltimore County, Md; St Paul, Minn; Chicago, Ill; and Los Angeles County, California.) Participants had no history of heart disease at enrollment. All underwent a heart scan (either EBT or multi-detector heart scans) at the start. It is therefore the largest prospective study involving heart scans ever performed. It is, not unexpectedly, yielding some fascinating observations relevant to the Track Your Plaque program. The MESA study is, incidentally, funded by the non-commercial, publicly-funded National Heart, Lung, and Blood Institute and is therefore presumably free of commercial bias.

Among the most recent publications is Risk factors for the progression of coronary artery calcification in asymptomatic subjects: Results from the Multi-Ethnic Study of Atherosclerosis (MESA) In this analysis of 5700 of the MESA participants, a repeat heart scan was obtained an average of 2.4 years after the first. Conventional risk factors for heart disease were obtained at the start (see below for details under Measurement of Covariates.)

After analyzing the data and risk factors assessed, such as age, sex, race, blood pressure, body mass index (BMI), presence of diabetes, blood sugar, and family history of heart disease, two questions were asked:

1) What risk factors predict heart scan scores?

2) What risk factors predict progression (i.e., increase) in heart scan scores?

(The second question is particularly relevant to us and the Track Your Plaque experience.)

The MESA analysis showed that essentially all the risk factors assessed correlated with both the initial heart scan score, as well as the rate of progression. No surprises here.

But the most eye-opening finding was that the conventional risk factors assessed explained only 12% of the variation and progression in heart scan scores (coefficient of determination, or R squared, = 0.12.) In other words:

--Conventional risk factors like LDL cholesterol, diabetes, and excess weight explain only a tiny fraction of why someone develops coronary atherosclerotic plaque as represented by a heart scan score.

--The great majority of risk for a high heart scan score remains unexplained by conventional risk factors.

--The great majority of risk for progressive increase in heart scan scores also remains unexplained by conventional risk factors.

In light of the MESA analysis, it's no surprise that strategies like reducing LDL cholesterol with statin drugs fails to prevent most heart attacks. It's no surprise that conventional prevention programs that talk about "knowing your numbers," eating a "balanced" or low-fat diet, etc., fail miserably to prevent the vast majority of heart attacks and heart procedures.

MESA confirms what we've been saying these past few years: If you want control over coronary heart disease, you won't find it in Lipitor, a low-fat diet, and other limited conventional notions of risk. Correction of conventional risk factors like cholesterol and blood pressure are, in a word, a failure. I wouldn't even call the conventional approach Track Your Plaque-Lite. They don't even come close.

If conventional risk factors can explain only 12% of the reason behind heart disease, we've got to look elsewhere to understand why you and I develop this process.

Measurement of Covariates
Information on demographics, smoking, medical conditions, and family history was collected by questionnaire at the initial examination. Height and weight were also measured at the baseline examination, and blood was drawn for measurements, including lipids, inflammation, fasting glucose, fibrinogen, and creatinine. Resting blood pressure was measured 3 times in the seated position, and the average of the last 2 measurements was used in the analysis. Medication use was determined by questionnaire. Additionally, the participant was asked to bring to the clinic containers for all medications used during the 2 weeks before the visit. The interviewer then recorded the name of each medication, the prescribed dose, and frequency of administration from the containers.

Risks for coronary disease 2008

31. December 2007 William Davis (27)

According to conventional thinking, there are identifiable risks for coronary disease and heart attack. These risk factors are:

* smoking
* high blood pressure
* high blood cholesterol and excessive saturated fat intake
* diabetes
* being overweight or obese
* physical inactivity

I'd agree with all the factors listed (though I would argue about the importance of high blood cholesterol and saturated fat; they are not as important as commonly made to be.)

Is the list complete?

From the unique perspectives gained in the Track Your Plaque program, I'd offer a significantly different list. Trying to stop or reduce coronary atherosclerotic plaque and heart scan scores makes you a whole lot smarter about what works and what doesn't work.

So, in addition to the risk factors listed above, I would add:

* Small LDL particles--Lots of small LDL particles is MORE important than high LDL.
* High blood pressure with exercise
* Excessive wheat intake and other processed carbohydrates--An issue of explosive importance today. Wheat creates large numbers of small LDL particles, among other adverse effects.
* Vitamin D deficiency--Among the most powerful risks I know of. It belongs at the top of the list.
* Vitamin K2 deficiency
* Low HDL cholesterol
* Blood sugar >100 mg/dl
* High triglycerides--While some argue about whether triglycerides are a risk that behaves independently of patterns like low HDL, they are neglecting the potent force of this risk. Sure, it occurs in tandem with low HDL (usually, though not always), but it is a factor that can leave you with risk even when HDL is raised to healthy levels.
* Lipoprotein(a)--It is eminently, positively crystal clear that lipoprotein(a) is a powerful risk for heart disease. The lack of a profitable treatment keeps it hidden in the shadows.
* Pessimism--Be happy, do better. Be a constantly angry, frustrated, complaining sourpuss and you are more likely to succumb to heart disease, cancer, or other undesirable fate.

These are the risk factors that we address through the Track Your Plaque program, a list that yields a far more powerful and comprehensive approach to control over coronary plaque/atherosclerosis, sufficient to achieve reversal in many (though not in all) instances.

I view the list of conventional risk factors as a "no brainer" list. Sure, smoking is a risk factor. But there are virtually no smokers in the Track Your Plaque program. If you smoke, you clearly don't care enough to engage in a high-intensity prevention program like this.

Saturated fat? Perhaps, but the battlefield of heart disease is riddled with the bodies of those who employed this as their sole strategy and failed catastrophically.

Diabetes, hypertension, and overweight all represent a continuum of risk; the solutions offered in the conventional scheme (i.e., low-fat diet, etc.) make these patterns worse, not better.

The conventional response to heart disease risk is trapped somewhere in 1973 and has not changed in over 30 years. Heart disease continues to be a growth industry for hospitals and the pharmaceutical and medical device industries. The "official" organizations continue to deliver an antiquated, outdated message.

If you want heart disease, follow the American Heart Association diet. If you want established heart disease to get worse, follow the American Heart Association diet. If you want diabetes or, if you already have diabetes or pre-diabetes, if you want it to worsen and develop organ damage (eyes, kidneys, nervous system, etc.), then follow the American Diabetes Association diet. USDA food pyramid? Loosen your belt!

The list of conventional risk factors for heart disease is woefully inadequate. If that is as far as your prevention program takes you, heart disease will not be controlled or prevented. At best, it might be slowed; at worst--and more likely--it might be accelerated.

Food sources of vitamin K2

27. December 2007 William Davis (46)

Vitamin K2 is emerging as an exciting player in the control and possible regression of coronary atherosclerotic plaque. Only about 10% of dietary vitamin K intake is in the K2 form, the other 90% being the more common K1.

The ideal source of K2 is natto, the unpalatable, gooey, slimy mass of fermented soybeans that Japanese eat and has been held responsible for substantial decreases in osteoporosis and bone fractures of aging. Natto has an ammonia-like bouquet, in addition to its phlegmy consistency that makes it virtually inedible to anyone but native Japanese.

I say that the conversation on vitamin K2 is emerging because of a number of uncertainties: What form of vitamin K2 is best (so-called MK-4 vs. MK7 vs. MK-9, all of which vary in structure and duration of action in human blood)? What dose is required for bone benefits vs. other benefits outside of bone health? Why would humans have developed a need for a nutrient that is created through fermentation with only small quantities in meats and other non-fermented foods?

Much of the developing research on vit K2 is coming from the laboratories of Drs. Vermeer, Geleijnse, and Schurgers at the University of Maastricht in the Netherlands, along with several laboratories in Japan, the champions of K2.

MK-7 and MK-8,9,10 come from bacterial fermentation, whether in natto, cheese, or in your intestinal tract; MK-4 is naturally synthesized by animals from vitamin K1. While natto is the richest source of the MK-7 form, egg yolks and fermented cheeses are the richest sources of the MK-4 form.

Chicken contains about 8 mcg MK-4 per 3 1/2 oz serving; beef contains about 1 mcg. Egg yolks contain 31 mcg MK-4 per 3 1/2 oz serving (app. 6 raw yolks). Hard cheeses contain about 5 mcg MK-4 per 3 1/2 oz serving, about 70 mcg of MK-8,9; soft cheeses contain about 30% less. Natto contains about 1000 mcg of MK-7, 84 mcg MK-8, and no MK-4 per 3 1/2 oz serving.

Feta cheese

Thanks to the research efforts of the Dutch and Japanese groups, several phenomena surrounding vitamin K2 are clear, even well-established fact:

--Vitamin K2 supplementation (via frequent natto consumption or pharmaceutical doses of K2) substantially improves bone health. While K2 by itself exerts significant bone density/strength increasing properties in dozens of studies, when combined with other bone health-promoting agents (e.g., vitamin D3, prescription drugs like Fosamax and calcitonin), an exaggerated synergy of bone health-promoting effects develop.

--The MK-4 form of vitamin K2 is short-lived, lasting only 3-4 hours in the body. The MK-7 form, in contrast, the form in natto, lasts several days. MK-7 and MK-8-10 are extremely well absorbed, virtually complete.

--Bone health benefits have been shown for both the MK-7 and MK-4 forms.

--Coumadin (warfarin) blocks all forms of vitamin K.

Interestingly, farm-raised meats and eggs do not differ from factory farm-raised foods in K2 content. (But please do not regard this as an endorsement of factory farm foods.)

Another interesting fact: Since mammals synthesize a small quantity of Vit K2 forms from vitamin K1, then eating lots of green vegetables should provide substrate for some quantity of K2 conversion. However, work by Schurgers et al have shown that K1 absorption is poor, no more than 10%, but increases significantly when vegetables are eaten in the presence of oils. (Thus arguing that oils are meant to be part of the human diet. Does your olive oil or oil-based salad dressing represent fulfillment of some subconscious biologic imperative?)

If we believe the data of the Rotterdam Heart Study, then a threshold of 32.7 micrograms of K2 from cheese yields the reduction in cardiovascular events and aortic calcification.

It's all very, very interesting. My prediction is that abnormal (pathologic) calcium deposition will prove to be a basic process that parallels atherosclerotic plaque growth, and that manipulation of phenomena that impact on calcium depostion also impact on atherosclerotic plaque growth. Vitamins D3 and K2 provide potential potent means of at least partially normalizing these processes.

As the data matures, I am going to enjoy my gouda, Emmenthaler, Gruyere, and feta cheeses, along with a few egg yolks. I'm going to be certain to include healthy oils like olive and canola with my vegetables.

Track Your Plaque: Naughty or nice?

24. December 2007 William Davis (6)

Among the many wonderful surprises we've had at Track Your Plaque this holiday season was a letter from Santa Claus himself!

It seems that Santa, like the rest of us, has been busy surfing the web for useful health information the last few months. He was struck with this curious discussion we've been having about "wheat belly" and all the unhealthy consequences of wheat products in our diet.

He writes:

"I wouldn't have believed it myself, except that my waist size has grown four inches in as many years. Sure, I'm known for my healthy girth, but now even Mrs. Claus calls me fat!

"I was open to new ideas when I came across this crazy discussion about eliminating wheat from your diet. So I said, "What have I got to lose?" Well, four weeks later and 12 lbs lighter, I'm convinced. Now comes the tough part: I've got to deliver all the toys and resist all those cookies the children put out for me. I wonder if wheat makes reindeer fat, too?

"Anyway, thanks to your program I'm back to my old weight again. Doc says my blood sugar and blood pressure are also back down to normal. Thanks, Track Your Plaque! (You'll find something extra special under the tree this year.)"

And so it goes. I'm tempted to put Santa's testimonial on our homepage, but I think that may be tooting our own horn a bit too much.

Have a wonderful holiday!

Vitamin D: Treatment for metabolic syndrome?

21. December 2007 William Davis (44)

Metabolic syndrome is that increasingly common collection of low HDL cholesterol, high triglycerides, high blood sugar, and high pressure that now afflicts nearly 1 in 4 adults, rapidly gaining ground to 1 in 3. Beyond these surface factors, metabolic syndrome also creates small LDL particles, VLDL, intermediate-density lipoproteins (IDL), increased imperceptible inflammation measured as higher c-reactive protein, and greater blood clotting tendencies. Metabolic syndrome is usually, though not always, associated with a big tummy ("beer belly," though I call it "wheat belly").

In short, metabolic syndrome creates a metabolic mess that leads to dramatic increases in heart disease, vascular disease and stroke, and cancer. The medical community has been paying increasingly greater attention to this condition because of its booming prevalence and because of the big bucks invested in "education" by the manufacturers of the diabetes and pre-diabetes drugs, particularly makers of Actos and Avandia.

But here's a curious observation:

Replacement of vitamin D to healthy levels (we aim for 50-60 ng/ml, or 125-150 nmol/l) yields:

--Higher HDL
--Lower triglycerides
--Lower blood sugar
--Reduced c-reactive protein
--Reduced blood pressure
--Reduced small LDL
--Enhanced sensitivity to insulin

(Whether blood clotting and effects on IDL should be added to this list is uncertain.)

It's obvious: Vitamin D is proving to be a very important and powerful corrective influence on many of the facets of the metabolic syndrome. In fact, I would go as far as saying that, side by side, vitamin D yields nearly the same effect as prescription drugs Actos and Avandia--without the extravagant cost (nearly $200 per month), leg swelling, congestive heart failure and heightened heart attack risk (with Avandia), and average 8 lb weight gain. Of course, vitamin D also provides benefits beyond metabolic syndrome like facilitation of coronary plaque regression, increased bone density, reduced arthritis, and reduced risk of several cancers.

You'd think that agencies like the American Diabetes Association (ADA) would be all over vitamin D like white on rice. Yet they remain curiously quiet about the entire issue. (That should come as no surprise to anyone familiar with the behavior and politics of this organization, the same outfit that has widely propagated the ADA diet, a program that accelerates diabetes and its complications. In my view, the ADA is an embarassment.)

For a really great story and video on vitamin D that includes a terrific interview with vitamin D guru and Track Your Plaque friend, California psychiatrist Dr. John Cannell, go to What's the Real Story on Vitamin D?. While the video will yield little new to readers of The Heart Scan Blog or Track Your Plaque members, it just feels really good to see a well-made, high-class video production echoing many of the things we've been talking about these past two years.

Appetite stimulants

20. December 2007 William Davis (17)

Ever have days when you just can't seem to get enough to eat, your stomach gnawing just a hour after a meal? We all get them, some more than others. Other days, you can be content with a few simple foods and hunger is subdued, temptation easy to control.

Why such contrasts on different days?

A major part of the reason can be the presence of appetite stimulants, factors that trigger appetite beyond rational control. The list of common appetite stimulants includes:

--Sleep deprivation--A very important factor. Lack of sleep drives tremendous appetite, and often for the wrong foods (processed carbohydrates). I personally have experienced my most shamefully indulgent days when sleep-deprived. The solution is obvious: Sleep. Another factor that is based purely on personal observation is that of waking mid-phase. In other words, waking up while you're still enjoying the deeper phases of sleep (e.g., phase 3,4, or REM). This can oddly disrupt your day and your impulse control. I usually try and time sleep to increments of 90 minutes to coincide with the average duration of the full cycle of sleep. For example, 7 1/2 hours is better than 8 hours, since the extra half hour puts your square into a deeper sleep cycle.

--Excessive caffeine--Caffeine stimulates stomach acid. This triggers the impulse to eat . . . and eat and eat.

Image courtesy Wikipedia

--Aspirin and other anti-inflammatory agents--If you take aspirin (as many of our Track Your Plaquers do), then beware of the gastritis that can develop. Like excessive caffeine, it also triggers the impulse to eat, likely a protective mechanism, since food sops up excess acid. I ask patients to take periodic breaks from aspirin, e.g., a week off every two or three months, to allow the stomach to heal. Alternatively, an occasional dose of acid-suppressing medication is a safe practice, e.g., Pepcid AC 10-20 mg; Prilosec 10-20 mg.

--Wheat-containing foods--Followers of The Heart Scan Blog know my feelings on this. Wheat is a potent appetite stimulant: Eat something containing wheat like a pretzel or whole wheat bagel, and you want more. You may want more immediately, or a little later when your blood sugar plunges after the wheat-driven insulin surge. Solution: Dump the wheat, one of the most unhealthy food groups around.

--Alcohol--Though perhaps not a direct appetite-stimulating effect, the loss of impulse-control with alcoholic drinks can lead to overindulgence, often in the worst foods. Just beware.

--Hanging around with heavy people. Remember peer pressure? It can be subliminal. People with poor eating habits provide the silent message that it's okay to yield to impulse, overeat, overindulge, and choose the wrong foods.

--Stress--Whether through cortisol stimulation or other means, stress triggers appetite in some people. If you experience this and must give in, reach for raw nuts or nuts, rather than wheat snacks or chips. The effect will be minimal, perhaps even beneficial, rather than the bloating, appetite-stimulating, fattening effect of crackers, chips, or pretzels. This may be the same phenomenon as taking prescription steroids like prednisone.

--Short dark days, long nights--In other words, winter. Though just an anecdotal observation, I am convinced that vitamin D supplementation is an effective antidote to this effect. The short, dark days just don't bother you as much, perhaps not at all, and there's no impulse for comfort foods.

How about appetite suppressants? In this list I would include 1) raw nuts--especially almonds, walnuts, pecans, and pistachios, the sort with a fibrous covering and rich in monounsaturates, 2) other sources of plentiful healthy oils, e.g, use more olive oil in your salad or add it to hummus for your veggie dip, 3) space-occupying fibers such as glucomannan, inulin (such as in Fiber Choice), and psyllium seed products. Counteracting the above appetite stimulants like sleep deprivation is, of course, important.

The coming wheat frenzy, otherwise known as the holidays, is an especially important time to be aware of these effects. Eat, drink, and be merry--but with rational impulse control not driven by subconscious appetite stimulants.

"Heart scans are experimental"

18. December 2007 William Davis (25)

Let me warn you: This is a rant.

It is prompted by a 44-year old woman. She has a very serious lipoprotein disorder. Her family experiences heart attacks in their 40s and 50s. I asked for a heart scan. Her insurance companied denied it.

This is nothing new: heart scans, like mammograms, have not enjoyed reimbursement from most insurers despite the wealth of data and growing acceptance of this "mammogram" of the heart.

However, 10 minutes on the phone, and the "physician" (what well-meaning physician can do this kind of work for an insurance company is beyond me) advised me that, while CT heart scans for coronary calcium scoring are not covered, CT coronary angiograms are.

Now, I've been witnessing this trend ever since the big players in CT got involved in the game, namely Philips, Siemens, Toshiba, and GE. These are enormous companies with hundreds of billions of dollars in combined annual revenues. They, along with the lobbying power of cardiology organizations like the American College of Cardiology, have gotten behind CT coronary angiograms. This is most likely the explanation of why CT coronary angiograms have rather handily obtaining insurance reimbursement. Interestingly, the insurance company I was speaking to is known (notorious?) for very poor reimbursement practices.

A CT heart scan, when properly used, generates little revenue, a few hundred dollars to a scan center, barely enough to pay for a device that costs up to $2 million. However, CT coronary angiograms, in contrast, yield around $2000 per test. More importantly, they yield downstream revenues, since CT angiograms are performed as preludes to conventional heart catheterizations, angioplasty, stents, bypass surgery, etc. Now we're talking tens or hundreds of thousands of dollars revenue per test.

What puzzles me is that much of that increased cost comes out of the insurance company. Why would they support such tests if it exposes them to more costs? I'm not certain. It could be the greater pressures exerted by the big CT companies and powerful physician organizations. I seriously doubt that the insurance companies truly believe that heart scans for coronary calcium scoring are "experimental" while CT coronary angiograms are "proven." If all we did was compare the number of clinical studies that validate both tests, we'd find that the number of studies validating heart scans eclipses that of coronary angiograms several fold. Experimental? Hardly.

The smell of money by physicians eager to jump on the bandwagon of a new revenue-producing procedure is probably enough to have them lobby insurers successfully. In contrast, plain old heart scans just never garnered the kind of vigorous and vocal support, since nobody gets rich off of them.

If CT coronary angiograms are sufficiently revenue producing that my colleagues and the CT scanner manufacturers have managed to successfully lobby the health insurers, even one as financially "tight" as the one I spoke to today, well then I take that as testimony that money drives testing, as it does the behavior of hospitals, many of my colleagues, and can even force the hand of insurers.

Are you hungry?

6. December 2011 William Davis (43)

Eliminate modern high-yield semi-dwarf Triticum aestivum . . . and what is the effect on appetite?

A reduction in appetite is among the most common and profound experiences resulting from wheat elimination. I know that I have personally felt it: Wake up in the morning, little interest in breakfast for several hours. Lunch? Maybe I'll have a few bites of something. Dinner . . . well, I'd like to exercise first.

The wheatless report that:

--Appetite diminishes to the point where you can't remember whether you've eaten or not. It is not uncommon to miss a meal, perfectly content. Calorie intake drops by 400 calories per day, on average, calories you otherwise would not have needed but all went to . . . you know where.
--Hunger feels different: It's not the gnawing, rumbling hunger that plagues you every 2 hours. In its place, you will find that hunger feels like a soft reminder that, gee, maybe it's time to have something to eat because you haven't had anything in--what?--4 to 6 hours. And it's a subtle reminder, not a desperate hunt that makes you knock people aside at the food bar, steal coworkers' lunches stored in the refrigerator, salivating at the mere thought of food.
--The simplest foods satisfy--It no longer requires an all-you-can-eat buffet to satisfy, but a few small pieces of healthy food. (Yeah, but what happens to revenues at Kraft, Nabisco, and Kelloggs, not to mention the revenues at agribusiness giants ADM and Monsanto? Slash consumption by, say, 30%, you likewise slash revenues by 30%. What would shareholders say?)
--Even prolonged periods of not eating, i.e., fasting, is endured with ease.

Hunger and the relentless search for something to eat disappear for most people. By eliminating the appetite-stimulating properties of wheat, we return to a natural state of eating for sustenance, to satisfy physiologic need. We are no longer victims of this incredibly powerful appetite-stimulant called gliadin from wheat.

This is why many diets fail: They fail to remove this powerful appetite stimulant. You might eat only lean meats, limit your calories, and exercise 90 minutes per day, but as long as the gliadin protein is pushing your appetite button, you will want to eat more or you will have to mount monumental willpower to resist it. You can lose 20 pounds on phase 1 of the South Beach diet, for instance, only to regain it in phases 2 and 3 when "healthy whole grains" are added back.

So the key is to remove the gliadin protein from your life, i.e., eliminate all things wheat.

Chocolate . . . for adults only

30. November 2011 William Davis (22)

If you've got a serious chocolate addiction and you'd like to make it as healthy as possible, give this X-rated dark chocolate a try.

I call it X-rated because it is certain to not satisfy young, sugar-craving palates, but is appropriate for only the most serious chocolate craver. This is a way to obtain the rich flavors and textures of cocoa, the health benefits (e.g., blood pressure reduction, antioxidation) of cocoa flavonoids, while obtaining none of the sugars/carbohydrates . . . and certainly no wheat!

It is easy to make, requiring just a few ingredients, a few steps, and a few minutes. Set aside and save for an indulgence, e.g., dip into natural peanut or almond butter.

Ingredients:
8 ounces 100% unsweetened cocoa
5 tablespoons coconut oil, melted
1/2 cup dry roasted pistachios
1/4 cup whole flaxseeds or chia seeds
Truvia or other non-aqueous sweetener

Using double-boiler method, melt cocoa. Alternatively, melt cocoa in microwave in 15-20 second increments. Stir in coconut oil, pistachios, and flaxseeds or chia seeds. Stir in sweetener, mixing thoroughly. (Note that the sweetener must be non-aqueous, as water-based sweeteners will separate in the oils.)

Lay a sheet of parchment paper out on a large baking pan. Pour chocolate mixture slowly onto paper, tilting pan carefully to spread evenly until thickness of thick cardboard obtained. Place pan in refrigerator or freezer for 20 minutes.

Remove chocolate and break by hand into pieces of desired size.

"Friday is my bad day"

19. November 2011 William Davis (29)

At the start, Ted had a ton of small LDL particles. His starting (NMR) lipoprotien values:

LDL particle number: 2644 nmol/L

Small LDL: 2301 nmol/L

In other words, approximately 85% of all LDL particles were abnormally small. I showed Ted how to use diet to markedly reduce small LDL particles, including elimination of wheat, limiting other carbohydrates, and even counting carbohydrates to keep the quantity no higher than 15 grams per meal ("net" carbs).

Ted comes back 6 months later, having lost 14 pounds in the process (and now with weight stabilized). Another round of lipoproteins show:

LDL particle number: 1532 nmol/L

Small LDL: 799 nmol/L

Better, but not perfect. small LDL persists, representing nearly 50% of total LDL particle number.

So I quiz Ted about his diet. "Gee, I really stick to this diet. I have nothing made of wheat, no sugars. I count my carbs and I almost never go higher . . . except on Fridays."

"What happens on Friday?" I asked.

"That's when I'm bad. Not really bad. Maybe just a couple of slices of pizza. Or I'll go out for a big custard cone or something. That wouldn't do it, would it?"

That's the explanation. Your liver is well-equipped to recognize normal, large LDL particles. Large LDL particles therefore "live" for only a couple of days in the bloodstream. But the human liver does not recognize the peculiar configuration of small LDL particles, so it lets them pass--over and over and over again. The result: Once triggered by, say two slices of pizza, small LDL particles persist for 5 days, sometimes longer.

So Ted's one "bad" day per week is enough to allow a substantial quantity of small LDL particles to persist. While a fat indulgence (if there is such a thing) pushes large LDL up, the effect is relatively short-lived. Have a carbohydrate indulgence, on the other hand, and small LDL particles persist for up to a week. It means that Ted's one "bad" day per week is enough to allow his small LDL particles to persist at this level, preventing him from gaining full control over coronary plaque.

It also means that, if you have blood drawn for lipoprotein analysis but had a carbohydrate goodie within the previous week, small LDL particles may be exaggeratedly high.

HDL 80 mg/dl

14. November 2011 William Davis (73)

More and more people in my clinic are showing HDL cholesterol values of 80 mg/dl or higher, males included.

Think about it: Nationwide, average HDL for males is 42 mg/dl and for females 52 mg/dl. Even though these average values are generally regarded as favorable, HDL cholesterol values at these levels are nearly always associated with higher levels of triglycerides, postprandial (after-eating) lipoprotein abnormalities, and excessive quantities of small LDL particles.

HDL particles are, of course, protective and are powerfully anti-oxidative. Higher levels of HDL have been associated with reduced potential for cancer, as well as reduced risk for heart disease.

Following the simple regimen that we follow to gain control over coronary plaque has therefore increased levels of HDL to heights that are uncommon in the rest of the population, levels that readily top 80, 90, or 100 mg/dl. That regimen includes:

1) Elimination of all wheat--Yes, consumption of "healthy whole grains" sets you up to have lower HDL levels; elimination of wheat increases HDL.
2) Limited carbohydrate consumption--While eliminating wheat is a powerful nutritional strategy to increase HDL, non-wheat carbohydrates like quinoa, millet, beans, rice, and fruit can still cause high triglycerides that lead to reduced levels of HDL. Limited exposure helps keep HDL at higher levels.
3) Omega-3 fatty acid supplementation--Because omega-3 fatty acids reduce both triglycerides and blunt the postprandial rise in lipoproteins that can cause HDL degradation, HDL rises with omega-3s from fish oil.
4) Vitamin D supplementation--The effect is slow, but it is BIG. HDL just goes up and up and up over about 2 years of supplementation. Before vitamin D, HDL levels of 60 mg/dl were the best I could hope for in most people. Now 80 mg/dl is an everyday occurrence.

Other factors can also be used to increase HDL levels, such as weight loss, red wine and alcohol, exercise, cocoa flavonoids, green tea, and niacin. But following the regimen above sends HDL through the roof in the majority.

Lessons from the 20-year statin experience

2. November 2011 William Davis (0)

Readers of the Heart Scan Blog know that, while I recognize that statins are useful in a small segment of the population with genetically-determined disorders, they are wildly overused, misused, and abused. In my view, the majority of people taking statins have no business doing so and could, in fact, obtain superior results by following some of the strategies advocated in these pages.

Nonetheless, the 30-year long statin experience has taught us some important lessons. Statin drugs have enjoyed more "research" than any other class of drugs ever conceived. They have received more media attention and embraced by more physicians than any other class of drugs. Combine these social phenomena and I believe that several lessons can be learned:

Small LDL particles and increased HbA1c--An evil duo

30. October 2011 William Davis (53)

Small LDL particles are triggered by consumption of carbohydrates. Eat more "healthy whole grains," for instance, and small LDL particles skyrocket.

Increased hemoglobin A1c, HbA1c, a reflection of the last 60-90 days' blood sugars, is likewise a reflection of carbohydrate consumption. The greater the carbohydrate consumption and/or carbohydrate intolerance, the greater the HbA1c. Most regard a HbA1c of 6.5% or greater diabetes; values of 5.7-6.4% pre-diabetes. However, note that any value of 5.0% or more signifies that the process of glycation is occurring at a faster than normal rate. Recall that endogenous glycation, i.e., glucose modification of proteins, ensues whenever blood sugars increase over the normal range of 90 mg/dl (equivalent to HbA1c of 4.7-5.0%). Glycation is the fundamental process that leads to cataracts, arthritis, and atherosclerosis.

Put the two together--increased quantity of small LDL particles along with HbA1c of 5.0% or higher--and you have a powerful formula for heart disease and coronary plaque growth. This is because small LDL particles are not just smaller; they also have a unique conformation that exposes a (lysine residue-bearing) portion of the apoprotein B molecule contained within that makes small LDL particles uniquely glycation-prone. Compared to large LDL particles, small LDL particles are 8-fold more prone to glycation.

So glycated small LDL particles are present when HbA1c is increased above 5.0%. Small, glycated LDL particles are poorly recognized by the liver receptor that ordinarily picks up and disposes LDL particles, unlike large LDL particles, meaning small LDL particles "live" much longer in the bloodstream, providing more opportunityt to do its evil handiwork. Curiously, small LDL particles are avidly taken up by inflammatory white blood cells that can live in the walls of arteries, where they are oxidized--"glycoxidized"--and add to coronary atherosclerotic plaque.

The key is therefore to tackle both small LDL particles and HbA1c.

Unforgiving small LDL particles

21. October 2011 William Davis (39)

Small LDL particles are triggered by carbohydrates in the diet: Eat carbohydrates, small LDL particles go up. Cut carbohydrates, small LDL particles go down.

A typical scenario would be someone starts with, say, 2000 nmol/L small LDL (by NMR) because they've been drinking the national Kool Aid of eating more "healthy whole grains" and consuming somewhere around 200 grams carbohydrates per day, including the destructive amylopectin A of wheat. This person slashes wheat followed by limiting other carbohydrates and takes in, say, 40-50 grams per day. Small LDL: 200 nmol/L.

In other words, reducing carbohydrate exposure slashes the expression of small LDL particles, since carbohydrate deprivation disables the liver process of de novo lipogenesis that forms triglycerides. Abnormal or exaggerated postprandial (after-eating) lipoproteins that are packed with triglycerides are also reduced. Because triglycerides provide the first lipoprotein "domino" that cascades into the formation of small LDL particles, carbohydrate reduction results in marked reduction in small LDL particle formation.

So let's say you are doing great and you've slashed carbohydrates. Small LDL particles are now down to zero--no small LDL whatsoever. What LDL particles you have are the more benign large variety, say, 1200 nmol/L (LDL particle number), all large, none small. You are due for some more blood work on Thursday. On Tuesday, however, you have four crackers because, what the heck, you've been doing great, you've lost 43 pounds, and have been enjoying dramatic correction of your lipoprotein abnormalities.

Your next lipoprotein panel: LDL particle number 1800 nmol/L, small LDL 700 nmo/L--substantially worse, with a major uptick in small LDL.

That's how sensitive small LDL particles can be to carbohydrate intake. And the small LDL particles can last for up to several days, since small LDL particles are not just smaller in size, they also differ in conformation, making them unrecognizable by the normal liver receptor. The small LDL particles triggered by the 4 crackers therefore linger, outlasting the normal-conformation large LDL particles that are readily cleared by the liver.

This phenomenon is responsible for great confusion when following lipoprotein panels, since a 98% perfect diet can yield dismaying results just from a minor indulgence. But, buried in this simple observation is the notion that small LDL particles are also extremely unforgiving, being triggered by the smallest carbohydrate indulgence, lasting longer and wreaking their atherosclerotic plaque havoc.

I eliminated wheat . . . and I didn't lose weight!

19. October 2011 William Davis (33)

Elimination of wheat is a wonderfully effective way to lose weight. Because saying goodbye to wheat means removing the gliadin protein of wheat, the protein degraded to brain-active exorphins that stimulate appetite, calorie consumption is reduced, on average, 400 calories per day. It also means eliminating this source of high blood sugar and high blood insulin and the 90-minutes cycles of highs and lows that cause a cyclic need to eat more at the inevitable low. It means that the high blood sugar and insulin phenomena that trigger accumulation of visceral fat are now turned off. It may possibly also mean that wheat lectins no longer block the leptin receptor, undoing leptin resistance and allowing weight loss to proceed. And weight loss usually results effortlessly and rapidly.

But not always. Why? Why are there people who, even after eliminating this appetite-stimulating, insulin-triggering, leptin-blocking food, still cannot lose weight? Or stall after an initial few pounds?

There are a list of reasons, but here are the biggies:

1) Too many carbohydrates--What if I eliminate wheat but replace those calories with gluten-free breads, muffins, and cookies? Then I've switched one glucose-insulin triggering food for another. This is among the reasons I condemn gluten-free foods made with rice starch, cornstarch, tapioca starch, and potato starch. Or perhaps there's too many potatoes, rices, and oats in your diet. While not as harmful as wheat, they still provoke phenomena that cause weight loss to stall. So cutting carbohydrates may become necessary, e.g., no more than 12-14 grams per meal.

2) Fructose--Fructose has become ubiquitous and has even assumed some healthy-appearing forms. "Organic agave nectar" is, by far, the worst, followed by maple syrup, honey, high-fructose corn syrup, sucrose,and fruit--yes, in that order. They are all sources of fructose that causes insulin resistance, visceral fat accumulation or persistency, prolongation of clearing postprandial (after-meal) lipoproteins that antagonize insulin, and glycation. Lose the fructose sources--as much of it as possible. (Fruit should be eaten in very small portions.) Watch for stealth sources like low-fat salad dressings--you shouldn't be limiting your fat anyway!

3) Thyroid dysfunction--A real biggie. Number one cause to consider for thyroid dysfunction: iodine deficiency. Yes, it's coming back in all its glory, just like the early 20th century before iodized salt made it to market shelves. Now, people are cutting back on iodized salt. Guess what's coming back? Iodine deficiency and even goiters. Yes, goiters, the disfiguring growths on the neck that you thought you'd only see in National Geographic pictures of malnourished native Africans. Number two: Exposure to factors that block the thyroid. This may include wheat, but certainly includes perchlorate residues (synthetic fertilizer residues) on produce, pesticides, herbicides, polyfluorooctanoic acid residues from non-stick cookware, polybrominated diphenyl ethers (flame retardants), and on and on. If you are iodine-deficient, it can even include goitrogenic iodine-blocking foods like broccoli, cauliflower, and soy. Thyroid status therefore needs to be assessed.

4) Cortisol--Not so much excess cortisol as disruptions of circadian rhythm. Cortisol should surge in the morning, part of the process to arouse you from sleep, then decline to lower levels in the evening to allow normal recuperative sleep. But this natural circadian cycling is lost in many people represented, for instance, as a flip-flopping of the pattern with low levels in the morning (with morning fatigue) and high levels at bedtime (with insomnia), which can result in stalled weight loss or weight gain. Cortisol status therefore needs to be assessed, best accomplished with salivary cortisol assessment.

5) Leptin resistance--People who are overweight develop an inappropriate resistance to the hormone, leptin, which can present difficulty in losing weight. This can be a substantial issue and is not always easy to overcome. It might mean assessing leptin levels or it might mean taking some steps to overcome leptin resistance.

Okay, that's a lot. Next: More on how to know when thyroid dysfunction is to blame.

Do the math: 41.7 pounds per year

14. October 2011 William Davis (21)

Consumers of wheat take in, on average, 400 calories more per day. Conversely, people who eliminate wheat consume, on average, 400 calories less per day.

400 calories per day multiplied by 365 days per day equals 146,000 additional calories over the course of one year. 146,000 calories over a year equals 41.7 pounds gained per year. Over a decade, that's 417 pounds. Of course, few people actually gain this much weight over 10 years.

But this is the battle most people who follow conventional advice to "cut your fat and eat more healthy whole grains" are fighting, the constant struggle to subdue the appetite-increasing effects of the gliadin protein of wheat, pushing your appetite buttons to consume more . . . and more, and more, fighting to minimize the impact.

So, if you eat "healthy whole grains" and gain "only" 10 pounds this year, that's an incredible success, since it means that you have avoided gaining the additional 31.7 pounds that could have accumulated. It might mean having to skip meals despite your cravings, or exercising longer and harder, or sticking your finger down your throat.

400 additional calories per day times 365 days per year times 300,000,000 people in the U.S. alone . . . that's a lot of dough. Is this entire scenario an accident?

Or, of course, you could avoid the entire situation and kiss wheat goodbye . . . and lose 20, 30, or 130 pounds this year.

We got the drug industry we deserve

14. October 2011 William Davis (6)

A biting commentary on just who is writing treatment guidelines for diabetes and cardiovascular disease was published in the British Medical Journal, summarized in theHeart.org's HeartWire here.

"About half the experts serving on the committees that wrote national clinical guidelines for diabetes and hyperlipidemia over the past decade had potential financial conflicts of interest (COI), and about 4% had conflicts that were not disclosed.

"Five of the guidelines did not include a declaration of the panel members' conflicts of interest, but 138 of the 288 panel members (48%) reported conflicts of interest at the time of the publication of the guideline. Eight reported more than one conflict. Of those who declared conflicts, 93% reported receiving honoraria, speaker's fees, and/or other kinds of payments or stock ownership from drug manufacturers with an interest in diabetes or hyperlipidemia, and 7% reported receiving only research funding. Six panelists who declared conflicts were chairs of their committee.

"Of the 73 panelists who had a chance to declare a conflict of interest but declared none, eight had undeclared COI that the researchers identified by searching other sources. Among the 77 panel members who did not have an opportunity to publicly declare COI in the guidelines documents, four were found to have COI."

The closing quote by Dr. Edwin Gale of the UK is priceless:
"Legislation will not change the situation, for the smart money is always one step ahead. What is needed is a change of culture in which serving two masters becomes as socially unacceptable as smoking a cigarette. Until then, the drug industry will continue to model its behavior on that of its consumers, and we will continue to get the drug industry we deserve."

It's like having Kellogg's tell us what to each for breakfast, or Toyota telling us what car to drive. The sway of the drug industry is huge. Even to this day, I observe colleagues kowtow to the sexy sales rep hawking her wares. But that's the least of it. Far worse, even the "experts" who we had trusted to have objectively reviewed the evidence to help the practitioner on Main Street appears to be little more than a hired lackey for Big Pharma, hoping for that extra few hundred thousand dollars.

In search of wheat: Emmer

23. June 2010 William Davis (13)

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

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

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

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

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

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

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

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

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

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

Thanks for subjecting yourself to these experiments! Very interesting. I have a friend who reacts poorly to wheat but tolerates spelt.

Wheat is eaten everywhere in the world. I'd hope GM crop scientists design a variety which can solve this problem.

If I am not mistaken, corn is also the result of the domestication of wild grasses existing some 8,000 years ago. Fooling with mother nature put us on a collision course with consequences.

My concern is that the body could be reacting without symptoms. Could these ancient grains cause inflammation even though there is no obvious reaction? I have lived 7 years without gluten and have no desire to add it back to my diet. Before I eliminated gluten I was very ill. It is not worth the risk to me.

Dr. Davis,

In your experience, in terms of small LDL and the like, what's better: a high peak of 150 that's brought down relatively quickly or a lower peak, but extended over a longer duration?

Thanks,
David

Anne--

Please don't interpret these casual observations to mean that we should eat einkorn.

My goal with this little experience is to gain an understanding of where along the way of wheat's 10,000+ year human consumption history did things go wrong.

It seems to me that humans could have gotten away with eating einkorn much more freely, with fewer health problems than with modern wheat. I still would like to know where the extreme adverse effects were acquired, however. I suspect this occured in the 1960s and 1970s with the hybridization experiments conducted in Mexico. more on that later.

No data. I suspect that the high peak is worse, but that is based on no formal data.

FODMAPs comprise a monosaccharide (fructose), a disaccharide (lactose), oligosaccharides (fructans and galactans), and polyols.

In one study, as obese people lose weight, the balance between the Firmicutes and the Bacteroidetes changes - the latter increasing in abundance as an overweight person gets slimmer.

Fructans, found in wheat, are fermented by bacteria in the large intestine into short chain fatty acids.

Besides human metabolism, the digestion of wheat is also affected by how it is metabolized by the particular intestinal flora inhabiting a person.

Fructose in the diet appears to be even more dangerous in the presence of trans-fats.

High Levels of Fructose, Trans Fats Lead to Significant Liver Disease, Says Study

"The investigators found that mice fed the normal calorie chow diet remained lean and did not have fatty liver disease. Mice fed high calorie diets (trans-fat alone or a combination of trans-fat and high fructose) became obese and had fatty liver disease.

"Interestingly, it was only the group fed the combination of trans-fat and high fructose which developed the advanced fatty liver disease which had fibrosis," says Dr. Kohli. "This same group also had increased oxidative stress in the liver, increased inflammatory cells, and increased levels of plasma oxidative stress markers.""

Your experience with einkorn and emmer is interesting. They do not seem to cause you the problems that wheat does, and that evidence supports the theory that they are less harmful than wheat. But the same evidence makes another theory equally plausible: that foods such as wheat harm you through pathways that form only through repeated exposure. Under this theory, einkorn and emmer could be just as harmful as wheat but, being novel to your diet, haven't had enough time for their pathways to form.

It would be interesting, then, to learn what happens if you were to incorporate einkorn or emmer into your diet more regularly.

Just wondering if you have experimented with fermenting the wheat or sprouting wheat and then drying it to make bread. I've read that making bread through this method helps celiac problems and wondered if there is a connection since soaking and/or sprouting neutralizes the phytic acid and supposedly aids in digestion and keeps blood sugars from rising as much.

Wondering if there is a difference in European wheat types verses American. I have illness, vomiting and nausea when I consume wheat here in the US. But when I tried it in France, Germany and Switzerland, I did not have any problems. I thought it might be the way US wheat is processed, but it might be the wheat type, as well.

Thank you,
Janet Creamer
