Firefighters Face Added Risk of Fatal Heart Attack

22. March 2007 William Davis (1)

Firefighters are twice as likely to die from a heart attack in the line of duty than are policemen, and three times more likely than EMTs.

That's among the headlines run today because of a report in the New England Journal of Medicine documenting a dramatically higher risk for heart attack for fire fighters putting out fires. The above headline is from an excellent report run on NPR radio. You can listen to the webcast at http://www.npr.org/templates/story/story.php?storyId=9047656.

The story sparked comments from experts insisting that all fire fighters should have physicals, should be in better physical condition, should be covered by health insurance (the NPR report said that 1 out of 4 fire fighters lack health insurance). Judging from the indisputable risk firefighters encounter, these are all good ideas.

But if you've been following my blog or the Track Your Plaque program, you know that physicals alone are hopeless exercises for identifying hidden heart disease. Among the solutions: identify whether or not heart disease is present in the first place--do a CT heart scan.

In fact, several local fire companies in my area have done just that: insisting that all firefighters undergo a heart scan. When groups of people like firefighters arrange for heart scans, they gain the advantage of doing so en masse, thereby allowing many scan centers to offer a dramatically reduced price to the city, town, or village that is paying for them. I've even seen many firefighters scanned at no cost.

It would also help to have health insurance, be physically fit, and have a stress test (an exception to my view that stress tests are also useless to screen asymptomatic people for heart disease). But a CT heart scan would settle the question quickly, easily, undeniably, and inexpensively.

Prophylactic bypass surgery?

20. March 2007 William Davis (0)

This question comes up around once a week:

My CT heart scan score is ____. Wouldn't I be better off just getting a bypass (or stent, etc.) and getting it over with? If I know that heart attack is in my future, why not just get it over with?

The most recent source of this question was the wife of a patient. Jack had a heart scan score of 92 in 2005. He made very little effort to correct his causes, permitting pre-diabetic patterns to persist, failed to correct vitamin D, etc. and a repeat heart scan score showed a dramatic rise to 264.

Jack's wife asked whether he should just have a bypass.

There are several problems with this line of reasoning:

1) Bypass surgery does not reduce the long term risk for heart attack.

2) The risk of bypass surgery often outweighs the risk of an asymptomatic heart scan score.

3) Bypass surgery is a temporary "fix," a fancy Band Aid for a disease that progresses after the procedure. One bypass typically prompts another, and another...

4) Bypassing arteries that have vigorous blood flow often causes the bypass graft to not "take" and close within the first few days.

Thankfully, nobody in his right mind has proposed that we perform prophylactic bypass operations.

Of course, hospitals and surgeons would jump at the chance to perform procedures in anybody with some threshhold heart scan score. It would double or triple their business overnight. At $70,000 or more per procedure, they would dance in glee. Of course, you and I would pay for their new burst of wealth by a sharp increase in our health insurance premiums. Not only that, the people who underwent the procedure would not benefit.

Lipitor 80 mg

20. March 2007 William Davis (4)

I'm seeing more and more people taking 80 mg of Lipitor per day. For the most part, these are people who come in for another opinion after a stent or heart attack and are prescribed the drug during their hospitalization.

This practice is based on the results of the PROVE IT-TIMI 22 (PRavastatin Or atorVastatin Evaluation and Infection Therapy-Thrombolysis In Myocardial Infarction) trial, and the Reversal of Atherosclerosis with Aggressive Lipid Lowering (REVERSAL) trial, both reported in 2005. In the PROVE IT Trial, 4,000 people experiencing heart attacks were treated with Lipitor (atorvastatin), 80 mg, or Pravachol (pravastatin), 40 mg. There was a reduction in events like recurrent heart attack from 13.1% in the Pravachol group to 9.6% in the Lipitor group. In the REVERSAL Trial, the Lipitor group also showed no plaque growth compared to the Pravachol group, which did progress, with disease tracked by intracoronary ultrasound.

I believe that many of my colleagues took the bait. In a half-hearted effort to reduce events and trend towards better coronary plaque control, writing a prescription for 80 mg rather than a lower dose has become increasingly popular.

Some problems: Despite the favorable tolerance to high dose Lipitor in these trials, I don't know anybody who can tolerate 80 mg per day for more than a few months in real life. In my experience, people inevitably end up with intolerable muscle aches.

Also, I believe it is folly to believe that we can regress coronary plaque on a broad scale by just using one drug that addresses only a single cause (i.e., LDL cholesterol). Yes, drug companies would argue that the statin drugs are so wonderful because of their so-called "pleiotropic", or non-lipid, effects like reducing inflammation. I have seen regression of plaque once using Lipitor alone. We struggle to reduce coronary plaque using a multi-faceted approach. It is highly unlikely that Lipitor alone at a 80 mg dose will be sufficient in most people to regress plaque. How about lipoprotein(a)? Or vitamin D deficiency? Lipitor has no effect on these patterns and people do not regress just by taking statin agents.

Orlistat for weight loss

19. March 2007 William Davis (3)

In early February, the FDA approved orlistat, formerly known as prescription Xenical, for over-the-counter sale. Orlistat is a blocker of fat absorption.

The new OTC version will be called "Alli" (pronounced like "ally") and will come at a dose of 60 mg to be taken three times a day with meals. Prescription Xenical came as a 120 mg tablet. However, the company claims that the reduced dose sacrifices only 5% in reduced fat absorption, dropping from 30% with Xenical to 25% with Alli. It will cost in the neighborhood of $1 to $2 per day, or $30-60 per month, far less expensive than the $110-150 for the prescription form.

Does it work? Is it worth the money? Clinical trials document around 5-10 lbs lost over a 3 to 6 month period, 50% greater than using diet and exercise alone.

Our experience is that it works, though inconsistently. Results depend heavily on how reliant you are on fat calories. If you were to follow a low-fat diet while on the drug, you likely will lose little or no weight, since there's little fat absorption to block. However, I have witnessed more substantial weight loss of 10-20 lbs. in people who follow a higher fat intake in their diet, e.g., a traditional American diet. However, these people gain the weight back immediately because they've made no effort to modify food choices.

It is messy. Even though the clinical trials claims modest inconvenient effects like gas and greasy stools, I have found that it is, without fail, a very annoying product that results in crampiness and frequent messy stools in nearly everybody.

The company has created a glitzy website that you can view at www.myalli.com and promises to provide a personalized program and support for registrants when it is up and running by summer 2007.

I think that's a good idea, since the drug itself is no more than a temporary fix unless it's combined with long-term diet changes. However, the website, I believe, oversells the value of the drug with a drug company's usual over-the-top hints and innuendoes without actually coming out with straight pitches of the truth.

Beware of the vitamin D-blocking effect of Orlistat. The period of time you take it may be a time to resort to some modest sun exposure (10-15 minutes; be careful not to burn), rather than than oil-based vitamin D capsules, in order to avoid the inevitable vitamin D plunge in blood level.

I am not a fan of orlistat, having seen it tried many times with minimal success. However, it is another option for those who are really struggling. Personally, I would try fasting or some of the other strategies we've detailed on the www.cureality.com website before I resorted to orlistat.

Low HDL makes Dr. Friedewald a liar

17. March 2007 William Davis (5)

There's a $22 billion industry based on treating LDL cholesterol, a fictitious number.

LDL cholesterol is calculated from the following equation:

LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5

So when your doctor tells you that your LDL cholesterol is X, 99% of the time it has been calculated. This is based on the empiric calculation developed by Dr. Friedwald in the 1960s. Back then, it was a reasonable solution, just like bacon and eggs was a reasonable breakfast and a '62 Rambler was a reasonable automobile.

One of the problems with Dr. Friedewald's calculation is that the lower HDL cholesterol, the less accurate LDL cholesterol becomes. If it were just a few points, so what? But what if it were commonly 50 to 100 mg/dl inaccurate? In other words, your doctor tells you that your LDL is 120 mg/dl, but the real number is somewhere between 170 and 220 mg/dl. Does this happen?

You bet it does. In my experience, it is an everyday event. In fact, I'm actually surprised when the Friedewald calculated LDL closely approximates true LDL--it's the exception.

Dr. Friedewald would likely have explained that, when applied to a large population of, say, 10,000 people, calculated LDL is a good representation of true LDL. However, just like saying that the average weight for an American woman is 176 lbs (that's true, by the way), does that mean if you weigh 125 lbs that you are "off" by 41 lbs? No, but it shows how you cannot apply the statistical observations made in large populations to a single individual.

The lower HDL goes, the more inaccurate LDL becomes. This would be acceptable if most HDLs still permitted reasonable estimation of LDL--but it does not. LDL begins to become significantly inaccurate with HDL below 60 mg/dl.

How to get around this antiquated formula? In order of most accurate to least accurate:

--LDL particle number (NMR)--the most accurate by far.

--Apoprotein B--available in most laboratories.

--"Direct" LDL

--Non-HDL--i.e., the calculation of total cholesterol minus HDL. But it's still a calculated with built-in flaws.

--LDL by Friedewald calculation.

My personal view: you need to get an NMR if you want to know what your LDL truly is. A month of Lipitor costs around $80-120. A basic NMR costs less than $90. It's a relative bargain.

Menopause unleashes lipoprotein(a)

16. March 2007 William Davis (0)

Faye was clearly frustrated.

At age 52, she was having chest pains every day. A CT heart scan showed a score of zero. A CT coronary angiogram showed no plaque whatsoever.

"Everything went downhill when my menopause started. I gained weight, I started to have chest pains, my blood pressure went up, my cholesterol shot up."

She saw three physicians, none of whom shed much light on the situation. They ran through the predictable sequence of (horse, not human) estrogens, anti-depressants, suggestions for psychological counseling.

But we checked Faye for lipoprotein(a), which she proved to have at a high level of 182 nmol/l. This explained a lot.

A curious and predictable set of phenomenon occur to females with Lp(a) proceeding through the menopause. As estrogen recedes:

--Lp(a) levels rise dramatically.

--Blood pressure goes up, sometimes creating severe hypertension by mid- to late-50s.

--Chest pain can develop, presumably due to "endothelial dysfunction" or "microvascular angina", both representing abnormal coronary artery constriction facilitated by worsening expression of Lp(a).

All too often, these phenomena get dismissed as simply part of the menopausal package, when they are, in fact, important facets of this very important genetic pattern that confers high risk for heart disease.

If any of this rings familiar for you or a loved one, think Lp(a). Though Faye hadn't yet developed any measurable coronary plaque by her CT heart scan score, it was likely on its way, given the surge in Lp(a) expression as menopause unfolded--unless its recognized and appropriate preventive action taken.

Vitamin D must be oil-based

15. March 2007 William Davis (0)

I've talked about this before, but I need to periodically remind everybody:
Vitamin D must be an oil-based capsule, a gel-cap, not a tablet.

Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago.

However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day.

She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.)

In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations.

You may have to look, but if you want to enjoy the extraordinary benefits of vitamin D replacement, it must be an oil-based capsule. Carlson's and Vitamin Shoppe have excellent prepartions. They raise blood levels substantially and consistently, and they're inexpensive. We pay $5.99 for a bottle of 120 capsules.

Vitamin D for $200?

13. March 2007 William Davis (2)

What if vitamin D cost $200 rather than $2?

In other words, what if cholecalciferol, or vitamin D3, was a patent-protectable agent that would sell for an extravagant price, just like a drug?

Vitamin D would be the hot topic. There would be TV ads run during Oprah, slick magazine two-page spreads with experts touting its outsized benefits, insurance companies would battle over how much your copay should be.

The manufacturer would host large fancy symposia to educate physicians on how wonderful vitamin D is for treatment of numerous conditions, complete with dinner, a show, and gifts. They would hire expert speakers to speak, scientists to have articles ghost-written, give out knick knacks with the brand label inscribed--just like Lipitor, Actos, Vytorin, ReoPro, Plavix . . .

After all, what other "drug" substantially increases bone density (up to 20% in adult females), enhances insulin responses 30% (equivalent to the TZD drugs, Actos and Avandia), and slashes colon cancer risk?

But it's not a drug. That is both vitamin D's strength and its weakness. It's a strong point because it's natural, phenomenally helpful across a variety of conditions, and inexpensive. It is also a weakness because, at $2 a month, no one is raking in the $12 billion annually that Pfizer makes for Lipitor that allows it to fund an enormous marketing campaign.

Vitamin D is a "discovery" of huge importance for health, including making reductions of CT heart scan scores far more likely for more people. And it comes without a prescription.

What's up with garlic?

13. March 2007 William Davis (0)

Fanatic Cook has posted an excellent summary on the recent negative attention cast on garlic preparations, at least for LDL cholesterol reduction.

Go to http://fanaticcook.blogspot.com to view.

I think Fanatic Cook is right--despite the lack of LDL reducing effects, it doesn't necessarily mean no benefit whatsoever. Anti-coagulation and anti-inflammatory effects, in particular, are well proven.

I do think, however, that it argues more in favor of sticking to whole cloves, rather than supplements. The benefits are also likely small. I would view garlic as a soft advantage for your plaque control program. You can do fine without it. You might do slightly better with it.

Drop the pretense

12. March 2007 William Davis (1)

Most hospitals maintain the "Saint _____" in their names, despite many having little or nothing to do with the church.

Out of 15 hospitals in my area, 13 are named after saints.

In my view, a more honest name would be something like "ABC Medical Enterprises, Inc." The profit motive, aggressive marketing tactics, and high CEO salaries would make better sense then. The trend to convert practicing physicians from professionals acting on behalf of patient welfare into paid employees would also be clearer.

Imagine Walmart were to change its name to "St. Mary's Emporium" Would it modify your perception of their business? I think it would. It would cause many people to believe that maybe their work was, at least in part, charitable and being done for the public welfare. But Walmart makes such pretense--they are in business for profit, just like all businesses.

It's time for the pretense to be dropped. Hospitals are cut-throat profit-seeking operations, operating under the guise of charitable, tax-free institutions. It's the farthest thing from the truth.

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.

You've come a long way, baby

3. June 2011 William Davis (16)

In 1945, the room-sized ENIAC vacuum tube computer was first turned on, women began to smoke openly in public, and a US postal stamp cost three cents. And this was the US government's advice on healthy eating:

Green and yellow vegetables; oranges, tomatoes, grapefruit; potatoes and other vegetables and fruits; followed by milk and milk products; meat, poultry, fish, or eggs; bread, flour, and cereals, butter and fortified margarine.

In 2011, the computing power of the ENIAC can be performed by a microchip a few millimeters in width, smoking is now banned in public places, and a first class postage stamp has increased in price by 1466%. And this is the new USDA Food Plate for Americans:

Have we made any progress over the past 65 years? We certainly have in computing power and awareness of the adverse effects of smoking. But have US government agencies like the USDA kept up with nutritional advice? Compare the 2011 Food Plate with the dietary advice of 1945.

It looks to me like the USDA has not only failed to keep up with the evolution of nutritional thought, but has regressed to something close to advising Americans to go out and buy stocks on the eve of the 1929 depression. Most of us discuss issues like the genetic distortions introduced into wheat, corn, and soy; the dangers of fructose; exogenous glycoxidation and lipoxidation products yielded via high-temperature cooking; organic, free-range meats and the dangers of factory farming, etc. None of this, of course, fits the agenda of the USDA.

My advice: The USDA should stay out of the business of offering nutritional advice. They are very bad at it. They also have too many hidden motives to be a reliable source of unbiased information.

Fasting with green tea

1. June 2011 William Davis (34)

I've been playing around with brief (18-24 hour) fasts with the use of green tea. Of the several variations on fasting, such as juice "fasts," I've been most impressed with the green tea experience.

While the weight loss effects of daily green tea consumption are modest, there seems to be a specific satiety effect that has now been demonstrated in multiple studies, such as this and this. In other words, green tea, through an uncertain mechanism, reduces hunger. The effect is not just due to volume, since the effect cannot be reproduced with hot water alone.

I therefore wondered whether green tea might be a useful beverage to consume during a fast, as it might take the "edge" off of hunger. While hunger during a fast in the wheat-free is far less than wheat-consuming humans, there is indeed an occasional twinge of hunger felt.

So I tried it, brewing a fresh 6-8 oz cup evert two hours or so. I brewed a pot in the morning while at home, followed by brewing single cups using my tea infuser at the office. Whenever I began to experience a hunger pang, I brewed another cup and sipped it. I was pleasantly surprised that hunger was considerably reduced. I sailed through my last 18 hours, for instance, effortlessly. The process was actually quite pleasant.

I brew loose Chinese bancha, sencha, and chunmee teas and Japanese gyokuro tea. Gyokuro is my favorite, but also the most expensive. Bancha is more affordable and I've used that most frequently.

If anyone else gives this a try, please report back your experience.

Dreamfields pasta is wheat

28. May 2011 William Davis (11)

An active question on the blogosphere and elsewhere is whether Dreamfields pasta is truly low-carb. Dr. Andreas Eenfeldt of Diet Doctor detailed his high blood glucose experience with it. Jimmy Moore of Livin' La Vida Low Carb had a similar experience, observing virtually no difference when compared to conventional pasta.

The Dreamfields people make the claim that "Dreamfields' patent-pending recipe and manufacturing process protects all but 5 grams of the carbohydrates per serving from being digested and therefore lessens post-meal blood glucose rise as compared to traditional pasta." They call the modified carbohydrates "protected" carbs.

In other words, they are making the claim that they've somehow modified the amylopectin A and amylose molecules in durum wheat flour to inhibit conversion to glucose.

I'd like to add something to the conversation: Dreamfields pasta is wheat. It is a graphic demonstration that, no matter how you cut it, press it, sauce it up, "protect" it, it's all the same thing: wheat. (It reminds me of a bad girlfriend I had in my 20s: She'd put on makeup, a pretty dress, I'd take her out someplace nice . . . She was still an annoying person who whined about everything.)

Wheat is more than a carbohydrate. It is also a collection of over 1000 proteins, including gliadins, glutens, and glutenins. Gliadins, for instance, are degraded to polypeptide exorphins that underlie the addictive potential of wheat, as well as its withdrawal phenomenon on halting consumption. Gliadin-derived exorphins are also the triggers of auditory hallucinations and paranoid delusions in schizophrenia, as well as behavioral outbursts in children with ADHD and autism.

Wheat is a source of lectins that have the curious effect of "unlocking" the proteins of the intestinal lining, the oddly-named "zonulin" proteins, that protect you from ingested foreign molecules. Ingest wheat lectins and all manner of foreign molecules gain entry into your bloodstream. Cholera works by a similar mechanism. (How about a love story: Bread in the time of cholera?)

Glutens, of course, are responsible for triggering celiac disease, the devastating small intestinal disease that now afflicts 3 million Americans, although 2.7 million don't even know it. Glutens are also responsible for neurologic conditions like cerebellar ataxia, peripheral neuropathy, and dementia ("gluten encephalopathy") and the skin condition, dermatitis herpetiformis.

Then there are the conditions for which the active wheat components have not been identified, including acid reflux, irritable bowel syndrome, asthma (excepting "bakers' asthma), rheumatoid arthritis, edema and fluid retention, and a long list of skin conditions from alopecia to gangrene.

My point: Yeah, Dreamfields pastas, from these instructive experiences, acts a lot like conventional durum wheat pasta. But, even if Dreamfields or somebody else perfects the low-carb aspect of it, it's still wheat. Modern wheat is the genetically tarted-up version of Triticum aestivum, the product of genetic shenanigans from the 1960s and 1970s.

Bet you can't fast

26. May 2011 William Davis (28)

People who continue to consume the world's most destructive grain, i.e., wheat, can rarely endure fasting--not eating for an extended period--except by mustering up monumental willpower. That's because wheat is a powerful appetite stimulant through its 2-hour cycle of exaggerated glycemia followed by a glucose low, along with its addictive exorphin effect. Wheat elimination is therefore an important first step towards allowing you to consider fasting.

Why fast? I regard fasting as among the most underappreciated and underutilized strategies for health.

In its purest form, fasting means eating nothing while maintaining hydration with water alone. (Inadequate hydration is the most common reason for failing, often experienced as nausea or lightheadedness.) You can fast for as briefly as 15 hours or as long as several weeks (though I tell people that any more than 5 days and supervision is required, as electrolyte distortions like dangerously low magnesium levels can develop).

Among its many physiological benefits, fasting can:

Reduce blood pressure. The blood pressure reducing effect can be so substantial that I usually have people hold some blood pressure medications, especially ACE inhibitors and ARB agents, during the fast since blood pressure will drop to normal even without the drugs. (A fascinating phenomenon all by itself.)

Reduce visceral fat, i.e., the fat that releases inflammatory mediators and generates resistance to insulin.

Reduce inflammatory measures

Reduce liver output of VLDL that cascades into reduced small LDL, improved HDL "architecture," and improved insulin responsiveness. (The opposite of fasting is "grazing," the ridiculous strategy advocated by many dietitians to control weight. Grazing, or eating small meals every two hours, is incredibly destructive for the opposite reason: flagrant provocation of VLDL production.)

Accelerate weight loss. One pound per day is typical.

Beyond this, fasting also achieves unique subjective benefits, including reduced appetite upon resumption of eating. You will find that as single boiled egg or a few slices of cucumber, for example, rapidly generate a feeling of fullness and satisfaction. Most people also experience greater appreciation of food--the sensory experience of eating is heightened and your sense of texture, flavors, sweetness, sourness, etc. are magnified.

After decades of the sense-deadening effects of processed foods--over-sugared, over-salted, reheated, dehydrated then just-add-water foods--fasting reawakens your appreciation for simple, real food. On breaking one of my fasts, I had a slice of green pepper. Despite its simplicity, it was a veritable feast of flavors and textures. Just a few more bites and I was full and satisfied.

Once you've fasted, I believe that you will see why it is often practiced as part of religious ritual. It has an almost spiritual effect.

More on fasting to come . . .

Total cholesterol 220

24. May 2011 William Davis (17)

Talking about total cholesterol is like wearing a tie-dyed t-shirt with the peace sign emblazoned on the front: So totally 60s and out of date.

But talk of total cholesterol somehow keeps on coming back. After I spend 45 minutes discussing a patient's lipoprotein patterns, for instance, they'll asking something like, "But what's my total cholesterol?"

To help put this ridiculous notion of total cholesterol to rest, let me paint several pictures of what total cholesterol can tell you. Let's start with a theoretical, but very common, total cholesterol value of 220 mg/dl. Recall that:

LDL cholesterol = total cholesterol - HDL cholesterol - triglycerides/5

Note that LDL cholesterol is nearly always a calculated value. (Yes, your doctor has been treating a calculated, what I call "fictitious," value.)

Rearranging the equation:

Total cholesterol = LDL cholesterol + HDL cholesterol + Triglycerides/5

This relationship means that a great many variations are possible, all under total cholesterol = 220 mg/dl. For example:

LDL 95 mg/dl + HDL 105 mg/dl + Triglycerides 100 mg/dl

(a relatively low-risk pattern for heart disease)

LDL 160 mg/dl + HDL 50 mg/dl + Triglycerides 50 mg/dl

(an indeterminate risk pattern, potentially moderate risk)

LDL 120 mg/dl + HDL 30 mg/dl + Triglycerides 350 mg/dl

(a potentially high-risk pattern)

LDL 60 mg/dl + HDL 25 mg/dl + Triglycerides 675 mg/dl

(an indeterminate risk pattern)

That's just a sample of the incredible variation of patterns that can all fall under this simple observation, total cholesterol 220 mg/dl.

Total cholesterol is an outdated concept, one ready long ago for the junk heap of outdated ideas. It's time to throw total cholesterol out in the trash along with beliefs like high-fat intake causes diabetes, whole grains are healthy, and the tooth fairy will leave you money when you leave your molars under the pillow.

Scientists are freakin' liars

14. May 2011 William Davis (3)

So says Tom Naughton, referring to the frequent misinterpretations or misrepresentations of data that characterize much medical research. Dr. Andreas Eenfeldt posted Tom Naughton's recent wonderfully engaging and hilarious talk from Jimmy Moore's Low-Carb Cruise on his Diet Doctor blog.

Comedian and blogger Tom Naughton, also the filmmaker of the movie Fat Head, has brought humor and personality into the low-carb movement. I told my wife to watch it and I could hear her laughing from 30 feet away while watching her laptop.

Dr. Eenfeldt is a sensation of sorts himself, making a big low-carb splash in Sweden. While I missed the cruise this year (due to time pressures), it's clear that Eenfeldt and Naughton have contributed substantially to helping people understand the nonsense that passes as dietary advice in the U.S. and the world.

I watched Naughton's talk while eating my three eggs scrambled with ricotta cheese. I almost spit my eggs out at the computer screen I was laughing so hard.
