Fish oil: What's the difference?

10. December 2010 William Davis (27)
Ultra-purified, pharmaceutical grade, molecularly distilled. Over-the-counter vs. prescription. Gelcap, liquid, emulsion.

There's a mind-boggling variety of choices in fish oil today. A visit to any health food store, or any "big box" store for that matter, will yield at least several, if not dozens, of choices, all with varying and often extravagant claims of purity and potency.

So what's the real story?

Given the analyses conducted over the years, along with my experience with dozens of different preparations, I believe that several conclusions can be reached about fish oil:

Fish oil is free of contamination with mercury, dioxin, PCBs, or furans. To my knowledge, only one fish oil preparation has been found to have a slight excess of PCBs. (This is different from cod liver oil that has been found by one source to have a slight excess of PCBs.)

Oxidative breakdown products differ among the various brands. Consumer Lab (http://www.consumerlab.org/), for instance, has found that several widely available brands of fish oil contained excessive oxidative breakdown products (TOTOX). You can perform you own simple test of oxidative breakdown products: Sniff it. Your fish oil should pass the "sniff test." High quality fish oil should smell non-fishy to lightly fishy. Rancid fish oil with excessive quantities of oxidative breakdown products will smell nasty fishy.

FDA approval does not necessarily mean greater potency, purity, or effectiveness. It just means that somebody assembled the hundreds of millions of dollars to obtain FDA approval, followed by lots of marketing savvy to squash the competition.

This means that there are a number of excellent fish oil products available. My favorites are the liquid fish oils from Pharmax, Nordic Naturals, and Barleans. Capsules from Carlson, PharmaNutrients, and Fisol have also performed consistently. The "big box" capsules from Sam's Club and Costco have also performed well and are wonderfully affordable.

Wheat-free pie crust

9. December 2010 William Davis (17)
I've been working on wheat-free yet healthy recipes these past two months.

You can buy wheat-free, gluten-free foods at the store, of course. But the majority of these products are unhealthy because cornstarch, rice starch, potato starch, or tapioca starch are commonly used in place of wheat. Recall that these are among the few foods that increase blood glucose higher than even wheat.

Here's a simple recipe for wheat-free pie crust that works best for cheesecake, pumpkin pie, and cream pies, but not for berry or other fruit pies like apple.

You will need:
?
1½ cups ground pecans
6 tablespoons melted butter?or melted coconut oil
1 teaspoon vanilla extract?
2 teaspoons cinnamon
1 medium egg
2 tablespoons Truvia™ or ½ teaspoon stevia extract or ½ cup Splenda®

Mix all ingredients thoroughly in bowl. Pour mixture into pie pan and press onto bottom and sides.

Fill pie crust with desired filling. You can fill it with your favorite cheesecake recipe (e.g., Neufchatel or cream cheese, sour cream, eggs, vanilla, and stevia; add pumpkin for pumpkin cheesecake) and bake, usually at 350 degrees F for one hour. 

Yes, the butter provokes insulin and artificial sweeteners can trigger appetite. But, for the holidays, a slice or two of pie made with this crust will not increase blood sugar nor trigger the uncontrolled impulse eating that wheat crust will trigger.

Here's a great insight dating all the way back to 1966 from one of the early explorations in lipoproteins from the National Institutes of Health lab of Levy, Lees, and Fredrickson:

The nature of pre-beta (very low density) lipoproteins

The subject is a 19 year old female (among the total of 11 in the this small, diet-controlled study) who was first fed a low-carbohydrate (50 grams per day), low-cholesterol diet; followed by a high-carbohydrate (500 grams per day), low-fat (5 grams per day) diet.






To B or not to B

5. December 2010 William Davis (11)
Apoprotein B (apo B) is the principle protein that resides in LDL particles along with other proteins, phospholipids, triglycerides, and, of course, cholesterol.

There's a curious thing about apo B. Just like one child per family in China or one television per household in 1950s America, there is only one apo B for every LDL particle.

So measuring apo B, in effect, provides a virtual count of LDL particles. (Actually, VLDL particles, the first lipoprotein to emerge from the liver, also have one apo B per particle but LDL particles far outnumber VLDL particles.) While apo B structure can show limited structural variation from individual to individual, the effect on measured apo B is negligible.

One apo B per LDL particle . . . no more, no less. What about the other components of LDL particles?

The other components of LDL particles are a different story. Cholesterol and triglycerides in LDL particles vary substantially. Diet has profound effects on cholesterol and triglyceride content of LDL particles. A diet rich in carbohydrates, for instance, increases triglycerides in LDL particles while reducing cholesterol. This means that measuring cholesterol in the LDL fraction will be misleading, since cholesterol will be falsely low. LDL cholesterol is therefore a flawed means to assess the behavior and composition of LDL particles. In particular, when LDL particles become enriched in triglycerides, they go through a process that transforms them into small LDL particles, the variety most likely to cause atherosclerosis.

In other words, when the worst situation of all--an abnormal abundance of small LDL particles develops--it is usually not signalled by high LDL cholesterol.

Because apo B is not sensitive to the composition of LDL particles--high cholesterol, low cholesterol, high triglycerides, etc.--it is a superior method to characterize LDL particles. While apo B doesn't tell you whether LDL particles are big, small, or in between, it provides a count of particles that is far more helpful than measuring this deeply flawed thing called "LDL cholesterol."

(Even better: Count LDL particles and measure LDL size, since size gives us insight into sensitivity to oxidation, glycation, adhesiveness, ability to trigger inflammatory pathways via monocyte chemoattractant protein, various interleukins, tunor necrosis factor and others. This is why cholesterol panels should go the way of tie dye shirts and 8-track tapes: They are hopelessly, miserably, and irretrievably inaccurate. Cholesterol panels should be replaced by either apoprotein B or lipoprotein measures.)

Put lipstick on a dwarf

2. December 2010 William Davis (24)
Today, virtually all wheat products are produced from the Triticum aestivum dwarf mutant.

You might call it "multi-grain bread,""oat bread," or "flaxseed bread." You could call it "organic," "pesticide-free," "non-GMO," or "no preservatives." It might be shaped into a ciabatta, bruschetta, focaccia, or panini. It might be sourdough, unleavened, or sprouted. It could be brown, black, Pumpernickel, or white. It could be shaped into a roll, bun, bagel, pizza, loaf, pretzel, cracker, pancake, brioche, baguette, or pita. It could be matzah, challah, naan, or Communion wafers.

No matter what you call it, it's all the same. It's all from the dwarf mutant Triticum aestivum plant, the 18-inch tall product of hybridizations, backcrossings, and introgressions that emerged from genetics research during the 1960s and 70s.

According to Dr. Allan Fritz, Professor of Wheat Breeding at Kansas State University, and Dr. Gary Vocke at the USDA, over 99% of all wheat grown today is the dwarf variant of Triticum aestivum. (For you genetics types, Triticum aestivum is the hexaploid, i.e., 3 combined genomes, product of extensive hybridizations, while ancestral einkorn is a diploid, i.e., a single genome, grass. Hexaploid Triticum aestivum contains the especially hazardous "D" genome, the set of genes most commonly the recipient of genetic manipulations to modify the characteristics of flour, such as gluten content. Einkorn contains only the original "A" genome.)

No matter what you call it, add to it, how you shape it, etc., it's all the same. It's all the dwarf mutant product of tens of thousands of hybridizations.

You can put lipstick on a pig, but it's still a pig. By the way, lipstick may contain wheat.

What the Institute of Medicine SHOULD have said

1. December 2010 William Davis (47)
The news is full of comments, along with many attention-grabbing headlines, about the announcement from the Institute of Medicine that the new Recommended Daily Allowance (RDA) for vitamin D should be 600 units per day for adults.

What surprised me was the certainty with which some of the more outspoken committee members expressed with their view that 1) the desirable serum 25-hydroxy vitamin D level was only 20 ng/ml, and 2) that most Americans already obtain a sufficient quantity of vitamin D.

Here's what I believe the Institute of Medicine SHOULD have said:

Multiple lines of evidence suggest that there is a plausible biological basis for vitamin D's effects on cancer, inflammatory responses, bone health, and metabolic responses including insulin responsiveness and blood glucose. However, the full extent and magnitude of these responses has not yet been fully characterized.

Given the substantial observations reported in several large epidemiologic studies that show an inverse correlation between 25-hydroxy vitamin D levels and mortality, there is without question an association between vitamin D and mortality from cancer, cardiovascular disease, and all cause mortality. However, it has not been established that there are cause-effect relationships, as this cannot be established by epidemiologic study.

While the adverse health effects of 25-hydroxy vitamin D levels of less than 30 ng/ml have been established, the evidence supporting achieving higher 25-hydroxy vitamin D levels remains insufficient, limited to epidemiologic observations on cancer incidence. However, should 25-hydroxy vitamin D levels of greater than 30 ng/ml be shown to be desirable for ideal health, then vitamin D deficiency has potential to be the most widespread deficiency of the modern age.

Given the potential for vitamin D's impact on multiple facets of health, as suggested by preliminary epidemiologic and basic science data, we suggest that future research efforts be focused on establishing 1) the ideal level of 25-hydroxy vitamin D levels to achieve cancer-preventing, bone health-preserving or reversing, and cardiovascular health preventive benefits, 2) the racial and genetic (vitamin D receptor, VDR) variants that may account for varying effects in different populations, 3) whether vitamin D restoration has potential to exert not just health-preserving effects, but also treatment effects, specifically as adjunct to conventional cancer and osteoporosis therapies, and 4) how such vitamin D restoration is best achieved.

Until the above crucial issues are clarified, we advise Americans that vitamin D is a necessary and important nutrient for multiple facets of health but, given current evidence, are unable to specify a level of vitamin D intake that is likely to be safe, effective, and fully beneficial for all Americans.


Instead of a careful, science-minded conclusion that meets the painfully conservative demands of crafting broad public policy, the committee instead chose to dogmatically pull the discussion back to the 1990s, ignoring the flood of compelling evidence that suggests that vitamin D is among the most important public health issues of the age.

Believe it or not, this new, though anemic, RDA represents progress: It's a (small) step farther down the road towards broader recognition and acceptance that higher intakes (or skin exposures) to achieve higher vitamin D levels are good for health.

My view: Vitamin D remains among the most substantial, life-changing health issues of our age. Having restored 25-hydroxy vitamin D levels in over 1000 people, I have no doubt whatsoever that vitamin D achieves substantial benefits in health with virtually no downside, provided 25-hydroxy vitamin D levels are monitored.

Coronary calcium: Cause or effect?

28. November 2010 William Davis (25)
Here's an interesting observation made by a British research group.

We all know that coronary calcium, as measured by CT heart scans, are a surrogate measure of atherosclerotic plaque "burden," i.e., an indirect yardstick for coronary plaque. The greater the quantity of coronary calcium, the higher the heart scan "score," the greater the risk for heart attack and other unstable coronary syndromes that lead to stents, bypass, etc.

But can calcium also cause plaque to form or trigger processes that lead to plaque formation and/or instability?

Nadra et al show, in an in vitro preparation, that calcium phosphate crystals are actively incorporated into inflammatory macrophages, which then trigger a constellation of inflammatory cytokine release (tumor necrosis factor-alpha, interleukins), fundamental processes underlying atherosclerotic plaque formation and inflammation.

Here's the abstract of the study:
Proinflammatory Activation of Macrophages by Basic Calcium Phosphate Crystals via Protein Kinase C and MAP Kinase Pathways:

A Vicious Cycle of Inflammation and Arterial Calcification?

Basic calcium phosphate (BCP) crystal deposition underlies the development of arterial calcification. Inflammatory macrophagescolocalize with BCP deposits in developing atherosclerotic lesionsand in vitro can promote calcification through the release of TNF alpha. Here we have investigated whether BCP crystals can elicit a proinflammatory response from monocyte-macrophages.BCP microcrystals were internalized into vacuoles of human monocyte-derived macrophages in vitro. This was associated with secretion of proinflammatory cytokines (TNF{alpha}, IL-1ß and IL-8) capable of activating cultured endothelial cells and promoting capture of flowing leukocytes under shear flow. Critical roles for PKC, ERK1/2, JNK, but not p38 intracellular signaling pathways were identified in the secretion of TNF alpha, with activation of ERK1/2 but not JNK being dependent on upstream activation of PKC. Using confocal microscopy and adenoviral transfection approaches, we determined a specific role for the PKC-alpha isozyme.

The response of macrophages to BCP crystals suggests that pathological calcification is not merely a passive consequence of chronic inflammatory disease but may lead to a positive feed-back loop of calcification and inflammation driving disease progression.


This observation adds support to the notion that increasing coronary calcium scores, i.e., increasing accumulation of calcium within plaque, suggests active plaque. As I say in Track Your Plaque, "growing plaque is active plaque." Active plaque means plaque that is actively growing, inflamed and infiltrated by inflammatory cells like macrophages, eroding its structural components, and prone to "rupture," i.e., cause heart attack. Someone whose first heart scan score is, say, 100, followed by another heart scan score two years later of 200 is exposed to sharply increasing risk for cardiovascular events which may, in part, be due to the plaque-stimulating effects of calcium.

Conversely, reducing coronary calcium scores removes a component of plaque that would otherwise fuel its growth. So, people like our Freddie, who reduced his heart scan score by 75%, can be expected to enjoy a dramatic reduction of risk for cardiovascular events.

Less calcium, less plaque to rupture, less risk.

Wheat one-liners

26. November 2010 William Davis (22)
If you're having difficulty convincing a loved one or someone else that wheat should be eliminated from the human diet, here are some useful one-liners to use:

Wheat makes your boobs big.
(This is true. Priceless for women to use on their husbands.)

Wheat causes dementia.
(And confirmed on examination of brain tissue at autopsy. Yes, autopsy.)

Wheat makes you look pregnant.
(The visceral fat of a wheat belly does a darn good imitation of a near-term infant.)

The first sign of wheat intolerance can be wetting your pants.
(Cerebellar ataxia, i.e., destruction and atrophy of the cerebellum, caused by wheat leads to loss of coordination and bladder control. Average age of onset: 53 years old.)

White flour bad, whole grain better; just as Marlboros are bad, Salems are better.
(The flawed syllogism that led to the "eat more healthy whole grain" colossal blunder.)

Wheat is the only food with its very own mortality rate.
(Celiac disease, osteoporotic hip fractures, and the neurologic diseases triggered by wheat can be fatal.)

"Wheat" is no longer wheat; it's the dwarf mutant that came from genetics research in the 1960s.
(Over 99% of all wheat today comes from the 18-inch tall dwarf mutant.)

Wheat increases blood sugar higher than nearly all other foods.
(Higher than Milky Way bars, higher than Snickers bars, higher than table sugar.)


There you have it: A full arsenal of one-liners to shoot at your husband, wife, or friend when they roll their eyes at your refusal to consume this thing called "wheat."

The happy homeotherm

24. November 2010 William Davis (14)
If you were a "cold blooded" poikilotherm unable to regulate internal body temperature, you would have to sun yourself on rocks to raise your body temperature, just like turtles and snakes. When it got cold, your metabolic rate would slow and you might burrow into the mud to hide.

You and I, however, are homeotherms, terrestrial animals able to regulate our own internal body temperature. Principal responsibility for keeping your body temperature regulated falls with the thyroid gland, your very own thermoregulatory "thermostat."

But internal body temperature, even in a homeotherm, varies with circadian rhythm: Highest temperature occurs in the early evening around 8 p.m.; the low temperature nadir occurs at around 4 a.m.

The notion that normal human temperature is 98.6 degrees Fahrenheit is a widely-held fiction, a legacy of the extraordinary experience of 19th century German physician, Carl Reinhold August Wunderlich, who claims to have measured temperatures of one million people using his crude, uncalibrated thermometer to obtain axillary (armpit) body temperatures.

Dr. Broda Barnes was a 20th century American proponent of using the nadir body temperature to gauge thyroid function. Like Wunderlich, Barnes also used axillary temperatures.

Modern temperature assessments have employed radiotransmitting thermistors that are swallowed, with temperatures tracked as the thermistor travels through the stomach, duodenum, small intestine, large intestine, rectum, then peek-a-boos back out. Such internal "core temperature" assessments have shown that:

--Axillary temperatures do not track with internal core temperatures very well, often veering off course due to external factors.
--Axillary temperatures are subject to ambient temperatures, such as room temperature, and are affected by clothing.
--Axillary temperatures are more susceptible to physical activity, e.g., increased with exercise or physical work.

Even right vs. left axillary temperatures have been shown to vary up to 2 degrees Fahrenheit.

Studies such as this demonstrate that normal oral temperature upon arising is around 97.2-97.3 degrees Fahrenheit. While we lack data correlating thyroid function with circadian temperature variation, the a.m. nadir does indeed, as Dr. Barnes originally suggested, seem to track thyroid status quite well: lower with hypothyroidism, higher with normal or hyperthyroidism.

I have been using 97.3 degrees F orally as the cutoff for confirming or uncovering thyroid dysfunction, particularly when symptoms or blood tests (TSH, free T3, free T4) are equivocal, a value that has held up well in the majority of cases. I find it helpful when, for instance, someone complains of cold hands and feet and has normal TSH (1.5 mIU/L or less in my view) but low free T3. An a.m. oral temperature of, say, 95.7 degrees F, suggests that there will be a favorable response to T3 supplementation. And it nearly always plays out that way.

Wouldn't it be interesting to know if there was insight into thyroid status provided by also examining the circadian behavior of temperature (e.g., height or timing of the peak)?

Statin buster?

19. November 2010 William Davis (20)
Merck recently reported preliminary results with its drug-in-development, anacetrapib.

After six months of treatment, participants showed:

LDL cholesterol was reduced from 81 mg/dl to 45 mg/dl in those taking anacetrapib, and from 82 mg/dl to 77 mg/dl in the placebo group.

HDL increased from 41 mg/dl to 101 mg/dl in the drug group, from 40 mg/dl to 46 mg/dl in those on placebo.

As you'd expect, the usual line-up of my colleagues gushed over the prospects of the drug, salivating over new speaking opportunities, handsomely-paid clinical "research" trials, and plenty of nice trips to exotic locales.

Anacetrapib is a cholesteryl-ester transfer protein inhibitor, or CETP inhibitor, much like its scrapped predecessor, torcetrapib . . . you know, the one that went down in flames in 2006 after 60% excess mortality occurred in people taking the drug compared to placebo. The hopes of many investors and Pfizer executives were dashed with torcetrapib's demise. The data on torcetrapib's lipid effects were as impressive as Merck's anacetrapib.

These drugs block the effects of the CETP enzyme, an enzyme with complex effects. Among CETP's effects: mediating the "heteroexchange" of triglycerides from triglyceride-rich VLDL particles that first emerge from the liver for cholesterol from LDL particles. This CETP-mediated process enriches LDL particles with triglycerides, which then make LDL a target for action by another enzyme, hepatic lipase, that removes triglycerides. This yields a several nanometer smaller LDL particle, now the number one most common cause of heart disease in the U.S., thanks to conventional advice to cut fat intake and increase consumption of "healthy whole grains."

With effects like this, anacetrapib, should it hold up under the scrutiny of FDA-required trials and not show the same mortality-increasing effects of torcetrapib, will be a huge blockbuster for Merck if release goes as scheduled in 2015. It will likely match or exceed sales of any statin drug. Statin drugs have achieved $27 billion annual sales, some of it deserved. Anacetrapib will likely handily match or exceed Lipitor's $12 billion annual revenue.

More than increasing HDL, CETP inhibition is really a strategy to reduce small LDL particles.

As with many drugs, there are natural means to achieve similar effects with none of the side-effects. In this case, similar effects to CETP inhibition, though with no risk of heightened mortality, is . . . elimination of wheat, in addition to an overall limitation of carbohydrate consumption. Not just low-carb, mind you, but wheat elimination on the background of low-carb. For instance, eliminate wheat products and limit daily carbohydrate intake to 50-100 grams per day, depending on your individual carbohydrate sensitivity, and small LDL drops 50-75%. HDL, too, will increase over time, not as vigorously as with a CETP inhibitor, but a healthy 20-30% increase, more with restoration of vitamin D.

Eliminating wheat and adjusting diet to ratchet down carbs is, of course, cheap, non-prescription, and can be self-administerd, criteria that leave the medical world indifferent. But it's a form of "CETP inhibition" that you can employ today with none of the worries of a new drug, especially one that might share effects with an agent with a dangerous track record.

One bite or many mouthfuls

6. January 2007 William Davis (0)
A reader brought this beautiful series of food photos to my attention:

http://www.wisegeek.com/what-does-200-calories-look-like.htm

It's simply a graphic display of what 200 calories of various foods look like. You'll note that vegetables and fruits permit large servings to yield 200 calories. Processed foods, on the other hand, require very little to tally up the same calorie load. In particularly, look how little in the way of wheat products are required to match that amount.

Heart scan curiosities #4

5. January 2007 William Davis (2)
Here's an interesting example of a 63-year old man with a heart scan score of 112. However, his aortic valve was also severely calcified (loaded with calcium). In other words, the normally flexible and mobile "leaflets" of the aortic valve were coated with calcium and other tissues that interfere with its free motion. The aortic valve is the starburst white in the center of the heart.








This is what the aortic valve should look like on a CT heart scan--you shouldn't see it at all.

The first man with the calcified valve will unfortunately require a new prosthetic aortic valve sometime in his future. This is usually determined with the help of an ultrasound, or echocardiogram, a better test for assessment of the aortic valve (though useless for detection of coronary plaque).

It's my suspicion that chronic and longstanding deficiency of vitamin D is among the factors that contribute to the abnormal deposition of calcium on the aortic valve. We desperately need more data on this. Nonetheless, perhaps this adds yet another reason to 1)get a CT heart scan, and 2) bring your vitamin D blood level to normal. (We aim for 50 ng/ml year round.)

Fish oil and the perverse logic of hospitals

4. January 2007 William Davis (6)
Hospitals are now starting to carry prescription fish oil, known as Omacor, on their formularies. It's used by some thoracic surgeons after bypass surgery, since fish oil has been shown to reduce the likelihood of atrial fibrillation (a common rhythm after heart surgery).

Why now? The data confirming the benefits of fish oil on atrial fibrillation has been available for several years.

It's now available in hospitals because it's FDA-approved. In other words, when fish oil was just a supplement, it was not available in most hospitals. Whenever I've tried to get fish oil for my patients while in hospital, you'd think I was trying to smuggle Osama Bin Laden into the place. The resistance was incredible.

Now that FDA-approved Omacor is available, costing $130 dollars per month for two capsules, $195 for the three capsule per day dose for after surgery, all of a sudden it becomes available. Why would this irrational state of affairs occur in hospitals?

Several reasons, most of which revolve around the great suspicion my colleagues have towards nutritional supplements. In addition, there's the litigation risk: If something has been approved by the FDA, their stamp of endorsement provides some layer of legal protection.

However, I regard those as pretty weak reasons. I am, indeed, grateful that fish oil is gaining a wider audience. But I think it's absurd that it requires a prescription to get it in many hospitals. Imagine, as the drug companies would love, vitamin C became a prescription agent. Instead of $3, it would cost far more. Does that make it better, safer, more effective?

Of course, no drug sales representative is promoting the nutritional supplement fish oil to physicians nor to hospitals. I now see people adding the extraordinary expense of prescription fish oil to their presription bills.

In my view, it's unnecessary, irrational, and driven more by politics and greed than actual need. Take a look at the website for Omacor (www.omacorrx.com). Among the claims:

"OMACOR is the only omega-3 that, along with diet, has been proven and approved to dramatically reduce very high triglycerides..."

This is a bald lie. Dozens of studies have used nutritional supplement fish oil and shown spectacular triglyceride-reducing effects.

Their argument against fish oil supplements:

"Dietary supplements are not FDA-approved for the treatment of any specific disease or medical condition. Get the Facts: nonprescription, dietary supplement omega-3 is not a substitute for prescription OMACOR."

Does that make any sense to you? Should you buy a GM car because only GM makes genuine GM cars? This is the silly logic being offered by these people to justify their ridiculous pricing.

How about: "The unique manufacturing process for OMACOR helps to eliminate worries about mercury and other pollution from the environment."

Funny...mercury in fish tends to be sequestered in the meat, not the oil. Independent reports by both Consumer Reports and Consumer Lab found no mercury, nor PCB's, in nutritional supplement fish oil. But just suggesting a difference without proving it may be enough to scare some people.

Just because something is used by a hospital does not make it better. The adoption of fish oil is hospitals is a good thing. Too bad it has to add to already bloated health care costs to enrich some drug manufacturer.

Repent for past sins

2. January 2007 William Davis (0)
If the food temptations of the holidays got the best of you, and you're now 5, 10, 15 lbs or more over your pre-holiday weight (our record is 18lbs!), then it's time for serious action.

One easy method to regain the control you may have lost is to pick some period, say, 3 days. During those three days, eat nothing but vegetables--no breads, meats, dairy products, certainly no cookies, cakes, pasta, etc., not even fruit. Follow this routine and weight drops rapidly. Vegetables are wonderful but sometimes boring, so use healthy condiments to spice them up: mustards (hot, brown, yellow, horseradish); healthy salad dressings, which are olive or canola oil-based; salsas, a fabulous garnish with no nutritional downside whatsoever; pesto; tapenades; horseradish added to other condiments or even by itself (wasabi).

Of course, fasting in one of its several variations is another rapid method to regain control. My favorite is to use soy milk in a modified fast, usually 4-6 glasses of a low-fat, low-sugar soy milk per day, along with plenty of water. (Please refer to the precautions detailed in the recent Track Your Plaque Special Report, Fasting: Fast Track to Control Plaque , particularly if you fast 5 days or longer or take blood pressure or diabetic medication.)

Of course, yo-yoing your weight--up during the holidays, down after their conclusion--is not good for you. It does raise the likelihood of diabetes, not to mention cultivate the patterns that contribute to coronary plaque growth, especially small LDL. But if temptation got out of control and you need to regain lost ground, these two strategies work fabulously well for most people.

If you've gained, say, 10 lbs during the holidays, but simply resume your usual habits, chances are you won't lose the weight. Year after year, this can add up to an enormous weight gain. The time to act is now. It's easier to lose the 10 lbs of weight you gained recently, rather than the 50 lbs you've stacked up over the past 5 years.

Wheat-free 2007

1. January 2007 William Davis (4)

Long ago, most of us made the change of reducing saturated fat in our diet. Few people now rely on butter (despite the idiotic butter vs. margarine controversy), full-fat dairy products, fried foods, and greasy meats. That's a healthy change, since saturated fat has conclusively been tied to various cancers, high blood pressure, rise in LDL, and is calorie-dense.

But if there were just one change you were to make beyond a reduction in saturated fat, a change that would translate into dramatic health benefits, it would be a drastic reduction, even elimination, of wheat products.

People do indeed eat enormous quantities of wheat flour-containing products. U.S. per capita consumption of wheat flour was 110 pounds in the early 1970s, and rose to 141 pounds in 1991. It's even higher now. 20% or more of most people's caloric intake every day is provided by wheat flour products.

Wheat containing foods are tasty and convenient. Witness the popularity of bagel shops, the goodie counter at Starbuck's, the proliferation of crackers, breads, and breakfast cereals at the grocery store. Patients are horrified when I suggest that they find a substitute for the sandwiches they eat every day. Even Mom said they were okay!

You're unlikely to hear much about this from the popular press. The wheat industry is enormous and exerts extraordinary clout, just like the drug industry. Texas alone farms 6 million acres of wheat, yielding over $2 billion for the state's economy. The "wheat chain" is complex and far-reaching: growers, processors, food manufacturers, the transportation industry, retailers, chemical producers, and on and on. Wheat futures are traded on the Chicago Board of Trade. Wheat is a major export industry for the U.S.

Of course, these are not evil people, intent on corrupting your health. In fact, most of them are probably working under the perception that they are raising a healthy product. The point is that the notion that wheat is healthy is deeply entrenched in the minds and economy of the U.S. Don't expect to hear unbiased commentary on the health effects of wheat products from most media sources.

What can you expect if you sharply reduce or eliminate wheat? The majority of people:

--Feel like a cloud has been lifted from their thinking.
--Don't experience the afternoon blah or tired feeling after lunch.
--Lose weight, sometimes substantial quantities.
--Raise HDL.
--Reduce small LDL.
--Reduce triglycerides, particularly if they start >100 mg/dl.
--Reduce blood sugar.

The reduction in small LDL can be especially impressive.

For most people, reducing or eliminating wheat is a sacrifice, a major change in food choices and even a loss of convenience. But the health benefits for most people can be dramatic.

Is vitamin D a "vitamin"?

29. December 2006 William Davis (5)
Vitamins are crucial participants in the body's reactions and are obtainable from food. Vitamin C, for example, comes from citrus fruits and vegetables. Vitamin K comes from green vegetables. The B vitamins are found in meats, soy, dairy products, and grains. Vitamin A comes from carrots, squash, and other orange and green colored vegetables.

How about vitamin D? What foods contain vitamin D? The list includes:


Food International Units(IU) vitamin D per serving

Cod liver oil, 1 Tablespoon 1,360
Salmon, cooked, 3½ ounces 360
Mackerel, cooked, 3½ ounces 345
Tuna fish, canned in oil, 3 ounces 200
Sardines, canned in oil, drained, 1¾ ounces 250

Milk, nonfat, reduced fat, and whole, vitamin D fortified, 1 cup 98
Margarine, fortified, 1 Tablespoon 60
Pudding, prepared from mix and made with vitamin D fortified milk, ½ cup 50
Cheese, Swiss, 1 ounce 12

Ready-to-eat cereals fortified with 10% of the DV for vitamin D, ¾ cup to 1 cup servings (servings vary according to the brand) 40

Egg, 1 whole (vitamin D is found in egg yolk) 20
Liver, beef, cooked, 3½ ounces 15

(Modified from the Office of Dietary Supplements, National Institutes of Health)


You'll note that the only naturally-occurring food sources of vitamin D are the modest quantities in fish, egg yolks, and liver. All the other vitamin D-containing foods like cereal, milk, and other dairy products have vitamin D only because humans add it.

It takes me (personally) 6000 units of vitamin D per day to bring my blood level to an acceptable 50 ng/ml. To obtain this from eating salmon, I would have to eat 58 ounces, or 3 1/2 pounds of salmon--every day. Or, I could eat 30 cans of tuna fish.

If I didn't want to eat loads of fish every day, I could drink 60 glasses of milk every day. After I recovered from the diarrhea, my vitamin D might be adequate, provided the milk indeed contained the amount stated on the label (which it often does not when scrutinized by the USDA).

If vitamin D is a vitamin, how are humans supposed to get sufficient quantities? I don't know anybody who can eat 3 1/2 lbs of salmon per day, nor drink 60 glasses of milk per day. But aren't vitamins supposed to come from food?




The problem is that vitamin D is not really a vitamin, it's a hormone. If your thyroid hormone level was low, you'd gain 20, 30, or more pounds in weight, your blood pressure would skyrocket, you'd lose your hair, become constipated, develop blood clots, be terribly fatigued. In other words, you'd suffer profound changes. Likewise, if thyroid hormone levels are corrected by giving you thyroid hormone, you'd experience profound correction of these phenomena.

That's what I'm seeing with vitamin D: restoration of this hormone to normal blood levels (25-OH-vitamin D3 50 ng/ml) yields profound changes in the body.

If there's one thing that I've come across lately that packs extraordinary potential to help us in reducing heart scan scores, it's the vitamin--sorry, the hormone--cholecalciferol, or D3.

Heart scan curiosities 3

28. December 2006 William Davis (0)

Note the shape of the chest in this 64-year old man. The front of his chest (upper portion of scan) is concave. In other words, if you were looking at this man (shirtless, of course) face to face, his chest would bow inward, rather than the usual outward configuration. The official name for this is "pectus excavatum".





Compare this to the normal chest in the second image, in which the chest is convex. Face to face, the chest would bow slightly outward.















What does it matter? The pectus excavatum in and of itself has no importance, just a curiousity. (I personally find this surprising, given the fact that the heart actually appears squashed by the sternum, or chest wall.) However, it is commonly associated with a "floppy" mitral valve (also called mitral valve prolapse), a common congenital disorder of the mitral valve often accompanied by a slender build, loose joints, and even a nervous disposition. Occasionally, in its more severe forms, the aorta is also enlarged. (This man's aorta is not enlarged.)

So, while we can't actually visualize the mitral valve by a CT heart scan, we can surmise that he likely has a floppy mitral valve, is slender, is probably a nervous sort, and has long limbs with loose joints. He probably required braces as a child, since many people have a phenemenon of "crowded teeth". The roof of his mouth, or hard palate, probably unusually high up in the mouth. He probably has a "weak chin", meaning a less prominent protuberance of his chin. His fingers and toes are likely unusually long and slender.

It could mean that some attention and exploration of how floppy his mitral valve might be could be useful, e.g., an ultrasound or echocardiogram. He might even require oral antibiotics at the time of any oral or some gastrointestinal procedures, since floppy valve are more susceptible to blood infections when potentially "dirty" orifices are instrumented.

All that from a heart scan!

Gratitude

24. December 2006 William Davis (2)
The holidays and the end of the year may be a good time to reflect on how grateful we should be for having the freedom to discuss the ideas we share on this Blog, the Track Your Plaque website, online and offline.

Although I rant and rave against the status quo in heart disease, the shameful profiteering of my colleagues and hospitals, the cut-throat marketing practices of drug and device manufacturers, I am truly grateful that, in the U.S., I have the extraordinary freedom to say these things. You have the freedom to agree or disagree and none of us pays a price for truth.

I've been reflecting myself a great deal on this idea of happiness and gratitude being a critical component of coronary plaque regression and dropping your heart scan score. (See The Heart Scan Blog from earlier this week.) The more I think about this, the more I think that it is indeed true: Harboring anger and resentment, regrets, irritability, all those petty emotions that most of us know are not good for us, erode our chances for success in dropping your heart scan score.

We could rationalize it this way: Anger and other negative emotions are adrenaline-driven states, also characterized by activation of the "sympathetic" nervous system. (Despite its name, the sympathetic system is not sympathetic, as in compassionate; its the "fight-or-flight" activator that accelerates heart rate and blood pressure.)

Happiness, contentment, and gratitude are "parasympathetic" states characterized by slower heart rates, deeper respiration, greater variation in beat-to-beat heart rates (a powerful predictor for health and the basis for the HeartMath program of Lew Childre), lower blood pressure, and even a subtle change in brain waves. In other words, happiness is not just a mental and emotional state, it is a constellation of physical phenomena.

Even though I pick on Dr. Dean Ornish for his stubborn adherence to the outdated low-fat mantra, I do agree with him on the value of happiness. His book, Love and Survival, articulates this concept. Ornish has even said on several occasions that it wasn't the diet that was most important but the connection and warmth that was created by the comraderie created by participation in the Ornish Program group sessions.

I am personally grateful that the concepts I promote are gaining a following and that I can say so without fear of prosecution. I am grateful that Track Your Plaque followers are not just sharing our concepts, but obtaining genuine and powerful health advice that will help keep them home and healthy, away from hospitals, procedures, and the dangers of heart disease.

I hope you share in my gratitude and are thankful for all the truly wonderful things that surround us. I wish you all a wonderful holiday and long, healthy life filled with gratitude.

A Track Your Plaque failure

23. December 2006 William Davis (0)
We recently had a man suffer a heart attack after beginning the program. Let me tell you the details.

Jerry's heart scan score 781, age 53. Multiple lipoprotein abnormalities: HDL 32 mg/dl, triglycerides 279 mg/dl, nearly all of his LDL was in small particles with an "effective" LDL (LDL particle number), and very high IDL. So Jerry added fish oil 6000 mg per day, niacin, and vitamin D to the statin drug prescribed by his primary physician. Jerry added oat bran, ground flaxseed, and tried to eat fish at least once per week.

However, Jerry continued to smoke. He'd smoked for 40 years (!), up to 2 packs per day, and just reasoned that it was too late to quit. He also continued to indulge in the packaged, processed foods that were part of his convenience story business.

Jerry's stress test was normal--no chest pain, normal EKG, normal images of blood flow, though he was somewhat breathless, likely from his lung disease from smoking.

Two months into his program, he abruptly experienced severe crushing pain in his chest. Because he was traveling, he ended up in a small local hospital. A failed angioplasty led to urgent coronary bypass surgery.

Jerry's alive. Now he's a non-smoker. He's got the pursed lips and peculiar breathing pattern that smokers get, but he's breathing.

Lesson: In the face of the most powerful program for heart disease known, it can still be overpowered by Twinkies, Hoho's, pretzels, chips--and cigarettes.

The new year is approaching. Be grateful for another year of healthy life and commit to a new year of even greater health. If you're a smoker, there's no choice: you've got to quit.

Are you more like a dog or a rabbit?

20. December 2006 William Davis (11)
Dr. William Roberts, editor of the American Journal of Cardiology and cardiovascular pathologist, is a perennial source of clever ideas on heart disease.
In a recent editorial, Dr. Roberts comments:








"Because humans get atherosclerosis, and atherosclerosis is a disease only of herbivorers, humans also must be herbivores. Most humans, of course, eat flesh, but that act does not make us carnivores. Carnivores and herbivores have different characteristics. (1) The teeth of carnivores are sharp; those of herbivores, flat (humans have some sharp teeth but most are flat for grinding the fruits, vegetables, and grains we are built to eat). (2) The intestinal tract of carnivores is short (about 3 times body length); that of herbivores, long (about 12 times body length). (Since I am 6 feet tall my intestinal tract should be about 60 feet long. As a consequence, if I eat bovine muscle [steak], it could take 5 days to course through those 20 yards.) (3) Body cooling for carnivores is done by panting because they have no ability to seat; although herbivores also can pant, they cool their bodies mainly by sweating. (4) Drinking fluids is by lapping them for the carnivore; it is by sipping them for the herbivore. (5) Vitamin C is made by the carnivore's own body; herbivores obtain their ascorbic acid only from their diet. Thus, although most human beings think we are carnivores or at least conduct their lives as if we were, basically humans are herbivores. If we could decrease our flesh intake to as few as 5 to 7 meals a week our health would improve substantially."



You can always count on Dr. Bill Roberts to come up with some clever observations.

I think he's right. Some of the most unhealthy people I've known have been serious meat eaters. Most of the vegetarians have been among the healthiest. (I say most because if a vegetarian still indulges in plenty of junk foods like chips, crackers, breakfast cereals, breads, etc., then they can be every bit as unhealthy as a meat eater.)

Should you become a vegetarian to gain control over coronary plaque and other aspects of health? I don't believe you have to. However, modern livestock raising practices have substantially modified the composition of meats. A steak in 2006, for instance, is not the same thing as a steak in 1896. The saturated and monounsaturated fat content are different, the pattern of fat "marbling" is different, the lean protein content is different. Meat is less healthy today than 100 years ago.

Take a lesson from Dr. Roberts' tongue-in-cheek but nonetheless provocative thoughts. Pardon me while I chew on some carrots.

Self-directed health: At-home lab testing

29. March 2009 William Davis (20)
I have a prediction.

I predict that more and more healthcare can and will be obtained directly by the individual--without doctors, without hospitals, without the corrupt profit-at-any-costs modus operandi of the pharmaceutical industry. I predict that, given the right tools, Joe or Jane Q. Public will have the choice to manage his or her own health using tools that are directly accessible, tools that include direct-to-consumer medical imaging (CT scans, ultrasound, MRI, etc.), nutritional supplements (a loosely-defined term, to our advantage), and direct-to-consumer laboratory testing.

Done responsibly, self-directed healthcare is superior to healthcare from your doctor. While no one expects you to remove your own gallbladder, you can manage cholesterol, blood sugar issues, vitamin D, low thyroid, and others--better than your doctor.

As everyone becomes more comfortable with the notion of self-directed health, you will see new services appear that help individuals manage their health. You will see prices for direct-to-consumer medical imaging and lab testing drop due to competition, something that doesn't happen in current insurance-based healthcare delivery. People are being exposed to larger deductibles and/or draw money from a medical savings account and will seek more cost advantages. Such direct-to-consumer competitive pricing will meet those needs. Overall, the presently unsustainable cost of healthcare will decline.

To help accelerate the shift of human healthcare away from conventional paths and divert it towards the individual, we have launched a panel of direct-to-consumer at-home laboratory tests that we are making available on the Track Your Plaque website.

On your own (except in California, which requires a doctor's order or prescription; and NY, the only state in the nation that prohibits entirely), you can now test, in the comfort of your own home with no laboratory blood draw required, parameters including:

--Thyroid tests--Free T3, free T4, TSH
--Lipids
--C-reactive protein
--Vitamin D
--Testosterone
--Progesterone

and others.

As the technology improves, more tests will become available for testing at home. (Lipoproteins are not yet available, but will probably be available within the next few years. That would be an enormous boon to those of us interested in supercharged heart disease prevention and reversal.)

Anyone interested in our at-home testing can just go to the Track Your Plaque lab test Marketplace.

When I first began the Track Your Plaque program around 8 years ago, I saw it as a way for people to learn how to control or reverse coronary atherosclerotic plaque, and I'd hoped that physicians would begin to see the light and become patient advocates in this process. But I have lost hope that most of my colleagues are interested in becoming your advocate in health. They are too locked into the "call me when you hurt" mentality. I now see Track Your Plaque as a way for people to seize control over coronary plaque with minimal assistance from their doctors. Indeed, some of our Members have achieved reduction of their plaque in spite of their doctors.

This is just the tip of the iceberg of what's to come. Brace yourself for a cataclysmic shift in returning health to you and away from those who would profit from your misfortune.

Vitamin D for Peter, Paul, and Mary

27. March 2009 William Davis (15)
Why is it that vitamin D deficiency can manifest in so many different ways in different people? One big reason is something called vitamin D receptor (VDR) genotypes, the variation in the receptor for vitamin D.

It means that vitamin D deficiency sustained over many years in:

Peter yields prostate cancer

Paul yields coronary heart disease and diabetes

Mary yields osteoporosis and knee arthritis.


Same deficiency, different diseases.

VDR genotype-determined susceptibility to numerous conditions have been identified, including Graves' thyroiditis, osteoporosis and related bone demineralization diseases, prostate cancer (Fok1 ffI genotype), ovarian cancer, rheumatoid arthritis, breast cancer (Fok1 ff), birth weight of newborns, melanoma and non-melanoma skin cancers, insulin resistance and metabolic syndrome, susceptibility to type I diabetes, Crohn's disease, and neurological or musculoskeletal deterioration with aging that leads to falls, respiratory infections, kidney cancer, even periodontal disease.


Why is it that the dose of vitamin D necessary to reach a specific level differs so widely from one person to the next? VDR genotype, again. Variation in blood levels of 25-hydroxy vitamin D from a specific dose of vitamin D can vary three-fold, as shown by a University of Toronto study. In other words, a dose of 4000 units per day may yield a 25-hydroxy vitamin D blood level of 30 ng/ml in Mary, 60 ng/ml in Paul, and 90 ng/ml in Pete--same dose, different blood levels.

Should we all run out and get our VDR genotypes assessed? So far the data have not progressed far enough to tell us. If, for instance, you prove to have the high-risk Fok1 ff genotype, would you do anything different? Would vitamin D supplementation be conducted any differently? I don't believe so.

Virtually all of us should be supplementing vitamin D at a dose that generates healthy blood levels, regardless of VDR genotype. For those of us following the Track Your Plaque program for coronary plaque control and reversal, that means maintaining serum 25-hydroxy vitamin D levels between 60-70 ng/ml.

As the fascinating research behind VDR genotype susceptibility to disease unfolds, perhaps it will suggest that specific genotypes be somehow managed differently. Until then, take your vitamin D.

Blowup at Milwaukee Heart Scan

26. March 2009 William Davis (20)
A local TV investigative news report just ran a critical report of the goings-on at Milwaukee Heart Scan:

Andy Smith went to Milwaukee Heart Scan. "It passed the smell test like a road kill skunk. I mean it was bad," Smith explained.

Our hidden cameras went inside the high pressure sales pitch. "On a good day I sell eight, nine, 10 people. On a bad day probably three," sales manager Angelo Callegari told us.


What the heck happened?

Let me tell you a story.

Back in 1996, I learned of a new technology called UltraFast CT scanning, or electron-beam tomography (EBT), a variation on the standard CT technology that permitted very rapid scanning, sufficiently rapid to allow visualization of the coronary arteries. Back then, only a few dozen devices had been established nationwide.

But the technology was so promising and the initial data so powerful that I lobbied several hospital systems in town to consider purchasing one of the $1.8 million devices. I was interested in applying this exciting technology for early detection of coronary heart disease in Milwaukee. While administrators from several hospitals listened, they quickly lost interest when they figured out that the scanner was primarily a tool for prevention, and would not be directly useful to increase revenue-generating hospital procedures.

I floundered about for a year, trying to drum up support for obtaining a scanner. The manufacturer of the device, Imatron, put me in touch with a couple from Indiana who were also interested in setting up a scanner and had actually obtained the investment capital to do it. We met and, over the next year, got Milwaukee Heart Scan up and running. I served as Medical Director (but never an investor or owner).

Milwaukee Heart Scan was busy from day one, performing EBT heart scans, as well as CT coronary angiograms as long ago as the late 1990s, virtual colonoscopies, and other imaging tests. We all spent a great deal of time educating the public and physicians on what this technology meant for detection and prevention of disease.

Despite the public's perception that the owners, Nancy and Steve Burlingame, were making a bundle of money, in reality they could barely pay their expenses. As price competition heated up in Milwaukee with the lower-cost competing multidetector scanners cropping up, the Burlingames often did not pay themselves.

My interest was to keep this device afloat. I therefore told the Burlingames that they should pay their bills first--their staff, overhead, the scanner costs, and pay themselves--and not worry about reimbursing me for the (very modest) heart scan interpretation fees. For several years, I read thousands of scans without any compensation. But that was okay with me--I just wanted to be sure this device remained available.

But in 2008, some business people from Chicago contacted Steve Burlingame with prospects of applying a contract model of long-term scanning to patients,i.e.,getting people to sign a several-year contract for discounted imaging. They proposed that Milwaukee Heart Scan offer heart scans for free to get people in the door.

What was peculiar about all this is that none of the four physicians on staff at Milwaukee Heart Scan had any knowledge of these discussions at all, including myself. Personally, I figured something was afoot when I came in to read scans in the summer of 2008. While, ordinarily, there is a single stack of scans to read from the preceding few days, this time there were numerous stacks of scans, hundreds of scans in all. Not a word had been said to me or my colleagues. I quickly figured out (thanks to the staff filling me in) that they had been offering scans for free. Not surprisingly, many people took them up on the offer.

Up until then, I had been readily willing to read heart scans without compensation, provided I could perform scan readings in a modest time commitment every week on the weeks it was my responsibility. But work several hours every day for free? Impossible.

My colleagues and I were deeply upset and concerned and insisted on a meeting with all the people involved, including the Burlingames, who had engineered this new sales program. We expressed serious reservations about what they were doing and insisted that they dramatically scale back the promises being made to people. I personally asked that they fire several of the people they had hired as sales people, given what we thought was unprofessional appearance and behavior.

The Burlingames and their new business partners essentially thumbed their noses at the physicians and ignored our advice. So, of the four physicians (one radiologist, three cardiologists), three of us resigned. (The one remaining cardiologist, I believe, didn't really understand what was going on.)

Apparently, after we left, the hard sales tactics continued. The news media got hold of the story through some understandably disgruntled people, and you know the rest.

The tragedy in all this is that, as wonderful as heart scans are, they don't make money for the people who invest in the technology. In the sad case of Milwaukee Heart Scan, it meant that my former friends, the Burlingames, turned to questionable tactics to make this technology pay.

Make no mistake: Heart scans remain a wonderful medical imaging modality. EBT, in particular, remains a fabulous technology that would--even today--remain the pre-eminent means to image coronary arteries, except that GE (who acquired Imatron some years ago) decided that a more direct path to bigger revenues was to purchase Imatron, then promptly scrap the entire operation, choosing to focus on multidetector technology exclusively.

Don't let the spotty past and petty ambitions cloud the fact that heart scans remain the best way to identify and track coronary plaque. Just don't get tempted by the offer of any free scans "without obligation."

Do you work for the pharmaceutical industry?

24. March 2009 William Davis (30)
In response to my post, Lovaza Rip-off, I received this angry comment:


Very high triglycerides, as you all know, is a very serious and life-threatening condition. Therefore, it is very important that any medication you take for treatment must be FDA proven and scientifically backed. This is true for a few reasons. First, there have been zero studies done to show the effects of Costco brand fish oil pills on patients with high triglycerides. So, you cannot assume, simply because the pills you are taking "claim" to have a certain amount of Omega 3 in the them, that they actually do (supplement labeling is self-submitted by the company, and not regulated by any external or 3rd party agency).

Secondly, the other components in fish oil, and maybe in Costco brand (no one knows because it isn't on the label) can actually inhibit the bioavailablity of Omega 3, most notably, Omega 6. And, nowhere on the Costco label does it tell you how much Omega 6 is in it. We also cannot underestimate the importance of purity with these compounds: a top selling brand of fish oil found stores like CVS was recently recalled because it was found to have large amounts of fire retardant in it! These supplements are NOT regulated by the FDA.

Thirdly, be careful when you compare costs. The cost of hospitalization due to acute pancreatitis (a risk of very high triglycerides) far outweighs the cost of taking Lovaza for even several years. If you have a real disease, you need a real drug. And, until Costco does a prospective long-term clinical trial to show that it lowers triglycerides, it should not be used in place of Lovaza.

Finally, I am a living example of how taking a high-potency supplement form of Omega 3 barely lowered my triglycerides, yet within 2 weeks of being on Lovaza there was a significant difference. I am now at my goal. So, before you knock a company, that, in my opinion, has saved my life, please do your research and do not mislead people into thinking that an Omega 3 is an Omega 3 is an Omega 3. If your insurance covers the most potent, the most pure, and the ONLY proven Omega 3 pill on the market, you should be thankful.


The comment was posted anonymously, so I don't know who it came from. But I can tell who I think it is: Someone who works for the drug industry.

This is a common phenomenon: Large corporations are fearful of the comments that are generated on internet conversations and other media. On the internet, there are actually people whose job it is to do "damage control." I suspect this came from one of them.

Why bother? Surely there are better things to do? Well, that's easy. There are billions of dollars at stake. Lovaza, in particular, is sold on the perception that it is somehow superior. If word gets out that maybe you can achieve the same results at a fraction of the cost . . .

Perhaps the "commenter" should also question whether omega-3 fatty acids can come from eating fish.

As part of my cardiology practice, I provide consultation on complex hyperlipidemias, or unusual lipid abnormalities. I have many patients with something called familial hypertriglyceridemia, a genetic condition that permits triglyceride levels of 500, 1000, even many thousands of mg/dl, levels that, as the anonymous commenter points out, can be dangerous.

I virtually never prescribe Lovaza for these people. In their treatment program, I use simple fish oil supplements, such as that from Costco, Sam's Club, or other retailers. I have not witnessed a single failure in treating these people and reducing triglycerides. People with lesser triglyceride abnormalities likewise respond very nicely to inexpensive fish oil that we can buy at the health food store. (I do rely on useful services like Consumer Reports and www.consumerlab.com to reassure us that no pesticide residues, mercury, or other contaminants are in the brands we use.) Excellent, high-quality fish oil supplements are sold by Carlson, Life Extension, Barlean's, even the Members' Mark brand from Sam's Club.

So, the notion that only prescription fish oil is capable of reducing triglycerides is, in a word, nonsense.

Take that back to your CEO.

Cholesterol effects of carbohydrates

24. March 2009 William Davis (31)
Let's take a hypothetical person, say, a 50-year old male. 5 ft 10 inches, 160 lbs, BMI 23.0. He's slender and in good health.

Our hypothetical man eats a simple diet of vegetables, some fruit, nuts, and meats but avoids processed industrial foods. By macronutrient composition, his diet is approximately 30% protein, 40-50% fat, 20-30% carbohydrate. His starting lipid panel:

Total cholesterol 149 mg/dl
LDL cholesterol 80 mg/dl
HDL 60 mg/dl
Triglycerides 45 mg/dl

His starting lipids are quite favorable (though I don't often see this kind of starting panel nowadays except in athletes). We begin here because this hypothetical man is going to serve as our test subject.

We ask our hypothetical man to load his diet up on "healthy whole grains." He complies by eating whole grain cereals for breakfast, whole wheat toast; sandwiches made with whole grain bread; dinners of whole wheat pasta; snacks of granola bars, whole wheat pretzels and crackers.

Three months later, his lipids show:

Total cholesterol 175 mg/dl
LDL cholesterol 130 mg/dl
HDL 45 mg/dl
Triglycerides 150 mg/dl


You can see that LDL cholesterol has increased, HDL has dropped, and triglycerides have increased. This wave of change is the hallmark of carbohydrate excess, but more specifically of overreliance on wheat products. Beyond his lipid panel, the man has gained 10 lbs, all concentrated in a soft roll around his abdomen, his blood sugar is now in the "borderline range" of between 110 and 126 mg/dl, i.e., pre-diabetic.

If we were to examine this man's advanced lipoproteins (e.g., NMR from Liposcience, or VAP from Atherotech), we would see that there has been an explosive increase in small LDL particles, along with a shift of large HDL to small, and the appearance of multiple abnormal classes of particles called VLDL and IDL (signalling abnormally slowed clearance of dietary by-products from the blood).

Familiar scenario? The "after-carbohydrate" situation is the rule among the people who I first meet who claim to be eating a "healthy" diet, though their patterns are usually much worse, with higher LDL, lower HDL, and much higher triglycerides, an exaggeration of our hypothetical man's abnormalities.

What if our hypothetical man now goes to his conventionally thinking (read "taught medicine by the pharmaceutical industry") physician? What will likely be the advice he receives? Reduce his saturated fat intake, eat plenty of healthy whole grains, take a statin drug.

Although my illustrative man is hypothetical, I've seen this scenario play out many thousands of times. It happens in real life all the time. It is predictable, it is highly manipulable. Sadly, it is rarely recognized for what it is: the result of excess carbohydrates, or what I call "Carbohydrate Intolerance Syndrome."

The misinterpretation of this condition has created 1) an epidemic of diabetes and pre-diabetes, 2) a nation of frustrated obese Americans, 3) a $27 billion per year statin industry, 4) another growth opportunity for the drug industry in diabetes drugs.

Wheat Belly Revisited

23. March 2009 William Davis (24)
Do you have a wheat belly?

When I first coined this phrase back in July, 2007, I had witnessed the phenomenal health effects of wheat elimination in several hundred patients.

In the nearly two years that have passed since my original post, I have witnessed hundreds more people who have done the same: eliminate pretzels, crackers, breads of all sorts, bagels, pasta, muffins, waffles, pancakes, etc.

If anything, I am convinced now more than ever that wheat is among the most destructive foods in the human diet. At least 70% of people who eliminate wheat from their diet obtain at least one, if not several, substantial health benefits.

Now, if I were trying to sell you something, say, an alternative to wheat, then you should be skeptical. If I tell you that drug or nutritional supplement X is great and you should take it, only to follow it with a sales pitch, you should be skeptical.

What am I selling? Nothing. I gain nothing by telling everyone to avoid wheat. In fact, I wish it wasn't true. Wheat foods taste good. Wheat flour makes great comfort foods. In years past, I spent many hours sitting at the bagel shop reviewing papers over a cup of coffee and a bagel. No longer.

So here, back by popular demand, the original Wheat Belly post:



Wheat Belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

Thank you, Crestor

20. March 2009 William Davis (9)
I'm sure everyone by now has seen the Crestor ads run by drugmaker, AstraZeneca. TV ads, magazine ads, and the Crestor website all echoing the same message:

"While I was busy building my life, something else was busy building in my arteries: dangerous plaque."

While previous drug trials with Mevacor, Pravachol, Zocor, and Lipitor have focused mostly on examining whether the drugs reduced incidence of cardiovascular events, Crestor studies have also focused on effects on atherosclerotic plaque volume. The best example is the ASTEROID trial that demonstrated approximately 7% reduction in plaque volume by intracoronary ultrasound.

So the AstraZeneca decision makers took the leap from cholesterol reduction to plaque reduction.

I'm sure this switch wasn't taken lightly, but was the topic of discussion at many meetings before the decision to make plaque reduction the focus of hundreds of millions of dollars of advertising. After all, billions of dollars are at stake in this bloated statin market.

Ordinarily, I couldn't care less about how the drug manufacturers conduct their advertising campaigns. But this one I paid attention to because the Crestor ads are helping fuel a new way of thinking about coronary heart disease: It's not about the cholesterol; it's about the atherosclerotic plaque that accumulates in arteries.

It's not cholesterol that grows, limits coronary blood flow, and causes angina. It's not cholesterol that "ruptures" its internal contents to the surface within the interior of the blood vessel and causes blood clot and heart attack. It's not cholesterol that fragments from the carotid arteries and showers debris to the brain, causing stroke. It's all plaque.

I took the same leap years ago, though not backed by hundreds of millions of dollars of marketing money. When I first called my book Track Your Plaque, some of the feedback I got from editors included comments like "I thought this was a book about teeth!" Even now, the word "plaque" in the book title and website is responsible for confusion.

But AstraZeneca is helping me clear up the confusion. As the word plaque gains hold in public consciousness, it will become increasingly clear that cholesterol reduction is not what we're after. We are looking for reduction of plaque.

If you are trying to develop an effective means to reduce or reverse coronary heart disease, then there are two simple equations to keep in mind:


Plaque = coronary heart disease

Cholesterol ? coronary heart disease


Plaque is the disease, cholesterol is not. Cholesterol is simply a crude risk for plaque.

While I'm no friend to the drug industry nor to AstraZeneca, some good will come of their efforts.

Supermarkets and buggy whips

17. March 2009 William Davis (17)
Will supermarkets eventually phase out, joining the history books as a phenomenon of the past? Or are supermarkets here to stay, an emblem of the industrialization of our food--easy access to foods that are convenient, suit the undiscriminating masses, stripped of nutritional value despite the prominent health claim on the package front?

Anna left an insightful comment on the last Heart Scan Blog post, Sterols should be outlawed, along with some useful advice on how to avoid this trap for poor health called a supermarket:


I rarely shop in regular supermarkets anymore (farm subscription for veggies, meat bought in bulk for the freezer, eggs from a local individual, fish from a fish market, freshly roasted coffee from a local coffee place, etc.). What little else I need comes from quirky Trader Joe's (dark chocolate!), the fish market, farmer's markets, a small natural foods store, or mail order.

When I do need to go into one of the many huge supermarkets near me, not being a regular shopper there, I never know where anything is, so I have to ramble a bit around the aisles before I find what I'm looking for (and I almost always can grab a hand basket, instead of a trolley cart).

It's almost like being on another planet! There's always so many new products (most of them I hesitate to even call food). It's really a shock to the senses now to see how much stuff supermarkets sell that I wouldn't even pick up to read the label, let alone put in a cart or want to taste. I'm not even tempted by 99% of the tasting samples handed out by the sweet senior ladies in at Costco anymore (only thing I remember tasting at Costco in at least 6 mos was the Kerrygold Irish cheese, because I know their cows have pasture access and it's real food).

What's really shocking to me is how large some sections of the markets have become in recent years. While Americans got larger, so did some sections of the supermarket (hint - good idea to limit the consumption of products from those areas). Meat and seafood counters have shrunk, though. Produce areas seem to be about the same size as always (but more of it is pre-prepped and RTE in packaging.

But the chilled juice section is h-u-g-e! And no, I don't think there is a Florida orange grove behind the cases. Come on, how much juice do people need? Juice glasses used to be teeny tiny, for a good reason. To me it looks like a long wall stocked full of sugar water. Avoiding that section will put a nice dent in the grocery expenses.

The yogurt case is also e-n-o-r-m-o-u-s! Your 115 yo Bulgarian "grandmother" wouldn't know what to make of all these "pseudo-yogurts"! Chock full of every possible variety, but very little fit to eat. The only yogurts I'll look at are made with plain whole milk, without added gums, emulsifiers, or non-fat milk solids, and live cultures (I mostly buy yogurt now and then to refresh my starter culture at home). I can flavor them at home if needed. The sterols are showing up in processed yogurts, too, along with patented new strains of probiotic cultures (I'll stick to my old fashioned, but time-proven homemade lacto-cultured veggies and yogurt instead).

I found the same "cooler spread" in the butter & "spread" section. The spread options were just grotesque sounding. Actually, the butter options weren't much better, as many were blended with other ingredients to increase spreadability, reduce calories or cholesterol/saturated fat, etc. A few plain butters were enhanced with "butter flavor" - say what? And on no package could it be determined if the butter came from cows that were naturally fed on pasture or on grain in confined pens.


Well said, Anna.

There's a huge supermarket about 1 mile away from my house similar to the one Anna describes with aisle after aisle of eye-catching cellophane-wrapped foods. I go there about every 3 or 4 months, and then I only go to get something I need in a pinch. Every time I go, I too am reminded just how many products there are that look more like junk food than real food.

But there's no real money in real food. Who gets rich off of selling green peppers, tomatoes, and eggs?

Supermarkets sell these modern industrial foods because people buy it: Look around you. You don't get to be a 250 lb 5 ft 2 inch-woman by eating too many cucumbers.

Like Anna, I drive an additional several miles to Trader Joes', buy at farmers' markets whenever possible, buy some odds and ends like wine and cheese and raw nuts at specialty stores. I grow my own basil in a big pot I keep in the kitchen and we are just about to start turning over the soil in the back yard for our vegetable garden. I don't need nor do I miss having the choice among 40 different chips, 25 brands of ready-made microwavable dinners, an entire aisle of breakfast cereasl (all of which are virtually the same with different names and labels), or 75 varieties of salad dressing.

The supermarket for me--and I hope for many of you--has become a place rarely frequented, and only for the odd forgotten item. Oh, I forgot the dog chewies the grocery does have--my dogs love them. So perhaps they are good for something after all.

Sterols should be outlawed

14. March 2009 William Davis (10)
While sterols occur naturally in small quantities in food (nuts, vegetables, oils), food manufacturers are adding them to processed foods in order to earn a "heart healthy" claim.

The FDA approved a cholesterol-reducing indication for sterols , the American Heart Association recommends 200 mg per day as part of its Therapeutic Lifestyle Change diet, and WebMD gushes about the LDL-reducing benefits of sterols added to foods.


Sterols--the same substance that, when absorbed to high levels into the blood in a genetic disorder called "sitosterolemia"--causes extravagant atherosclerosis in young people.

The case against sterols, studies documenting its coronary disease- and valve disease-promoting effects, is building:

Higher blood levels of sterols increase cardiovascular events:
Plasma sitosterol elevations are associated with an increased incidence of coronary events in men: results of a nested case-control analysis of the Prospective Cardiovascular Münster (PROCAM) study.

Sterols can be recovered from diseased aortic valves:
Accumulation of cholesterol precursors and plant sterols in human stenotic aortic valves.

Sterols are incorporated into carotid atherosclerotic plaque:
Plant sterols in serum and in atherosclerotic plaques of patients undergoing carotid endarterectomy.




Though the data are mixed:

Moderately elevated plant sterol levels are associated with reduced cardiovascular risk--the LASA study.

No association between plasma levels of plant sterols and atherosclerosis in mice and men.




The food industry has vigorously pursued the sterol-as-heart-healthy strategy, based on studies conclusively demonstrating LDL-reducing effects. But do sterols that gain entry into the blood increase atherosclerosis regardless of LDL reduction? That's the huge unanswered question.

Despite the uncertainties, the list of sterol-supplemented foods is expanding rapidly:




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












HeartWise orange juice contains 1000 mg sterols per 8 oz serving.













Promise SuperShots contains 400 mg sterols per container.














Corozonas has an entire line of chips that contain added sterols, 400 mg per 1 oz serving.














MonaVie Acai juice, "Pulse," contains 400 mg sterols per 2 oz serving.














Kardea olive oil has 500 mg sterols per 14 gram serving.










WebMD has a table that they say can help you choose "foods" that are sterol-rich.

In my view, sterols should not have been approved without more extensive safety data. Just as Vioxx's potential for increasing heart attack did not become apparent until after FDA approval and widespread use, I fear the same may be ahead for sterols: dissemination throughout the processed food supply, people using large, unnatural quantities from multiple products, eventually . . . increased heart attacks, strokes, aortic valve disease.

Until there is clarification on this issue, I would urge everyone to avoid sterol-added "heart healthy" products.

Texas state representative, Rene Oliveira, has introduced legislation that mandates heart scans for adults in the state of Texas.

Rep. Oliveira

A press release from the SHAPE Society ( Society for Heart Attack Prevention and Eradication) reads:

Assessment of heart attack risk on the basis of traditional risk factors alone such as high cholesterol and high blood pressure and so forth, while useful, misses many who are at high risk and also incorrectly flags some for high risk who are in fact at very low risk of near term heart attack; on the other hand detection of atherosclerosis by non-invasive imaging, as suggested by the SHAPE group, accurately identifies plaque and improves the ability to identify at-risk individuals who could benefit from aggressive preventive intervention while sparing low-risk subjects from unnecessary aggressive medical therapy," said Dr. P.K. Shah, Director of Cardiology at Cedars Sinai Heart Institute in Los Angeles, a leading member of the SHAPE Task Force who is also an active member of the American Heart Association. "Sadly, these vulnerable patients go undetected until struck by a heart attack, because insurance companies don't cover the newer heart attack screening imaging tests."


Rep. Oliveira, whose coronary disease was first uncovered by a heart scan and prompted a bypass operation, states:

"It is about time that we cover preventive screening for the number one killer in Texas, and take action to reduce healthcare costs through preventive healthcare. Right now, we are extending the lives of those who can afford the procedure while hundreds of thousands of Texans with hidden heart disease go undetected because of antiquated thinking. The time has come for this change."


Is this what we've come to? Since practicing physicians are either so entranced by the drug and procedural solutions to heart disease, do we need to resort to heart scan by legislation?

It does indeed appear that we've come to this point. Should this trend catch on, it will surely mean an upfront increase in healthcare costs to cover the expense of heart scans. But in the long run, it will mean reduction in healthcare costs--dramatic reduction--if heart scans prompt effective preventive action.
