The world according to the Wheat Foods Council and the Whole Grains Council

23. April 2010 William Davis (26)

You might get a kick out of what the Wheat Foods Council and the Whole Grains Council recommend for a sample meal plan:

Breakfast: Whole grain raisin toast
Lunch: Sandwich on whole grain
Snack: Rye bread crackers
Dinner: Whole grain pasta with your favorite sauce

Breakfast: Whole grain waffles 
Lunch: Hamburger on whole grain bun
Snack: Graham crackers
Dinner: Whole grain homemade pizza on whole grain pita crust

Remember Morgon Spurlock's documentary movie, Super Size Me? (If you haven't already seen it, Super Size Me is viewable for free on Hulu.) Spurlock conducts a self-inflicted 30-day experiment of eating at McDonald's fast food restaurants every day. In short, the results on Spurlock's weight and health are disastrous. 

How about Wheat Belly: The Movie? We would chronicle our star through a 30-day course of meals served up by the Wheat Foods and Whole Grains Councils, all featuring wonderful wheat products in every meal. We could measure blood sugar, triglycerides, LDL, small LDL, weight, etc.


Any predictions?

Why bananas increase cholesterol

21. April 2010 William Davis (0)
Anything that increases postprandial (after-eating) blood sugar will increase the number of LDL particles in the blood.

An increase in LDL particles is an important factor in causing heart disease: The greater the number of LDL particles, the more opportunity they have to interact with the walls of arteries, contributing to atherosclerosis.

Carbohydrates increase small LDL, especially if postprandial sugar is increased. Here's another way carbohydrates increase LDL particles: The duration of time LDL particles hang around in the blood stream is doubled.

When blood sugar increases, such as after the 30 grams carbohydrates in a medium-sized banana, glycation of LDL particles occurs. This means that a gglucose (sugar) molecule reacts with a lysine residue in the apoprotein B of the LDL particle. This induces a change in conformation that makes it less readily recognized by the LDL receptor. Thus, the glycated LDL particle persists for a longer period of time in the blood stream.

LDL particles are therefore cleared less efficiently, numbers of LDL particles increase.

Plant-based or animal-based?

19. April 2010 William Davis (78)
The ideal diet for heart and overall health restricts carbohydrate intake. I say this because carbohydrates:

Make you fat--Carbohydrates increase visceral fat, in particular.
Increase triglycerides
Reduce HDL
Increase small LDL particles
Increase glycation of LDL
Increase blood pressure
Increase c-reactive protein

Reducing carbohydrates reverses all the above.

But here's a common mistake many people make when following a low-carbohydrate diet: Converting to a low-carb, high-animal product diet.

It accounts for a breakfast of a 3-egg omelette with cheese and butter, 4 strips of bacon, 2 sausages, cream in coffee. Low-carb? It certainly is. But it is a purely high-animal product, no-plant-based meal.

I believe a strong argument can be made that a low-carbohydrate but plant-based diet with animal products as the side dish is a better way to go.

Consider that:

1) Animal products have little to no fiber, while plant-based products like spinach, avocado, and walnuts and other raw nuts have substantial quantities.

2) Plant products are a source of polyphenols and flavonoids--This encompasses a large universe of nutrients, from epigallocatechins in tea, polymeric procyanidins from cocoa, to hydroxytyrosol from olives, and anthocyanins from red wine and eggplant. The inflow of these beneficial compounds needs to be frequent and generous, not piddly amounts taken infrequently.

3) Vitamin C--While it's easy to obtain, the fact that you and I need to obtain vitamin C from frequent ingestion of plant sources suggests that humans were meant to eat lots of plants. While it may require a few months of deficiency before your teeth fall out, imagine what low-grade deficiency can do over a long period.

4) Vitamin K1--Rich in green vegetables, vitamin K1 is virtually absent in animal products.

5) Tocotrienols--I've been watching the data on this fascinating family of powerful oil-soluble antioxidants unfold for 20 years. Tocotrienols come only from plants. (I recently had an extended conversation with the brilliant biochemist, Dr. Barrie Tan, who is incredibly knowledgeable about tocotrienols, having developed several methods of extraction from plants, including his discovery of the highly concentrated source, annatto. Be sure to watch for future conversations about tocotrienols.)

6) Meats and dairy yield a net acid load--While plant foods are net basic. At the very least, this yields risk for osteoporosis, since acids are ultimately buffered by basic calcium salts from the bones. Tissue and blood pH is a tightly regulated system; veering off just a teensy-weensy bit from the normal pH of 7.4 to an acidic pH of, say, 7.2, leads to . . . death. In short, pH control is very important. A net acid challenge from animal products is a lot like drinking carbonated soda, a huge acid challenge that leads to osteoporosis and other health issues.

Conversely, a pure plant-based diet has its own set of problems. Eating a pure plant-based diet can lead to deficiencies of vitamin B12, omega-3 fatty acids (no, linolenic acid from flaxseed will NOT cut it), vitamin K2, carnitine, and coenzyme Q10.

So, rather than a breakfast of 3-egg omelet with bacon, sausage, cream, and cheese, how about a handful of pecans, some blueberries, and a 2-egg omelet made with basil-olive oil pesto? Or a spinach salad with walnuts, feta cheese, and lots of olive oil?

Fat is not the demon

16. April 2010 William Davis (36)
So my patient, Dane, generously volunteered to be on the Dr. Oz show, as I discussed previously.

What we didn't know, nor did the producer who contacted us mention, that Dane would be counseled by low-fat guru Dr. Dean Ornish on a strict low-fat diet. The teaser introduction essentially tells the entire story.

Ironically, that is the exact opposite of the dietary program that I advocate. I rejected the 10% fat diet long ago after I became a type II diabetic, gained 30 lbs, and suffered miserable deterioration of my cholesterol values on this diet. I also witnessed similar results in many hundreds of people, all following a strict low-fat diet. In fact, elimination of wheat--whole, white, or otherwise--along with limitation or elimination of all other grains has been among the most powerful health strategies I have ever witnessed.

I now regret having subjected my patient to this theatrical misinformation. Dane is a smart cookie--That's probably why he was not allowed more than a "yes" or "no" during Dr. Oz's monologue, else Dane might have pitched in about some ideas that would have tripped Oz and Ornish up.

In their defense, if we took 100 Americans all following a typical 21st century diet of fast food, white bread buns, Coca Cola and other soft drinks, chips, barbecue sauce, and French fries, converting to a plant-based, high-carbohydrate, grain-rich diet is indeed an improvement. People will, at first, lose weight and enjoy an initial response. (The occasional person with the Apo E4 genetic pattern, heterozygote or homozygote, may even enjoy long-term benefits, a topic for another day.)

But the majority of people, in my experience, after an initial positive response to an Ornish-like low-fat, high-carbohydrate diet will either plateau (stay overweight, have low HDL, high triglycerides, plenty of small LDL, and high blood sugars) or deteriorate, much as I did.

Thankfully, Dane has been a good sport about this, understanding that this is essentially show business. I believe he understands that the information was all well-intended and, after all, we are all working towards the same goal: reduction of heart disease risk.

By the way, regardless of which diet you follow, it is, in my view, absurd to believe that diet alone will do it. What about vitamin D normalization, thyroid normalization (thyroid disease is incredibly common), omega-3 fatty acids from fish oil, identification of hidden sources of risk (something that is unlikely in Ornish, since small LDL particles skyrocket on a low-fat diet), postprandial glucoses, etc., all the pieces we focus on to gain control over coronary plaque? Eating green peppers and barley soup alone is not going to do it.

Near-fatal brush with nattokinase

14. April 2010 William Davis (0)
Here is precisely why I have spoken out against nattokinase: People may put faith in this "supplement" when there are virtually no data to support its use in such dangerous conditions as pulmonary embolism.

Pulmonary embolism occurs when a large volume of blood clots in the veins of the pelvis, abdomen, and into the legs. A clot breaks off and lodges in the pulmonary arteries of the lungs. This can be fatal within minutes to hours, the victim struggling to breathe, since oxygen is not transferred to the blood and it causes terrible pain in the chest.

The treatments are fairly obnoxious: intravenous anticoagulants (blood thinners), followed by oral blood thinners like warfarin. While they carry risk of bleeding and other long-term risks, it's better than dying.

Would you bet that a "nutritional supplement" manufacturer's vague claims and lack of data are sufficient proof to treat a life-threatening condition? You're a fool if you are.

Anyone reading these pages knows that I am a vigorous supporter of nutritional supplements. I even consult for the nutritonal supplement industry. But I am also an advocate of TRUTH, not BS.

Here is a woman from England who inquired whether she should stop her husband's warfarin in favor of nattokinase. This is precisely the sort of thing that can happen because of the campaign of misinformation behind nattokinase.


Dr. Davis,

Thank you for your very interesting blogs, which I came across searching for natural alternative treatments to warfarin.

My husband has been following the low carb, high fat, real food regime over the past few years. He got off all the blood pressure and cholesterol drugs and never felt better. He even got his blood sugar down from a recorded high that we are aware of 13 nmol/L (234 mg/dol) to 6.1 nmol/L 109.8 mg/dl).

We were on holiday in the Caribbean. Just before our return home, we did a trip to a neighbouring island that included non-alcoholic fruit punches. They tasted great, but were very sweet. I broke my normal refusal to drink these things, but only had a couple of glasses. (After all, we were on holiday!) My husband believes he consumed around 1.5 litres of the stuff and now realises he was feeding his body a very toxic product – fructose. That night, he had an incredible toxic response and we only got him onto the plane with a visit to the hospital and a pain killer injection.

The symptoms of pulmonary embolism only showed 2 weeks later . . . and warfarin treatment was started. We would both like to use an alternative therapy if we can find someone with experience to provide the support.Do you know of any studies that support alternative options?

Do you know of any practitioners in the England who support a non-drug approach with an understanding of nutrition who we may be able to receive advice and support?

Glucophobia: The Novel

13. April 2010 William Davis (25)
Just kidding: No novel here. However, there is indeed a story to tell that should scare the pants off you.

If you haven't yet gathered that carbohydrates are a macronutrient nightmare, let me recount the list:


Carbohydrates increase small LDL particles
Or, in the cholesterol-speak most people understand, "carbohydrates increase cholesterol." It's counterintuitive, but carbohydrates increase LDL substantially, far more than any fat.


Carbohydrates increase blood sugar
Eggs don't increase blood sugar, nor do chicken, raw almonds, onions or green peppers. But a bowl of oatmeal will send your blood sugar skywards.


Carbohydrates make you fat
Carbohydrates, whether in the form of wheat flour in your whole wheat bread, sucrose in your ice cream, fructose in your "organic Agave nectar," or high-fructose corn syrup in your dill pickles. They all provoke de novo lipogenesis, or fat formation. They also stimulate insulin, the hormone of fat storage.


Carbohydrates cause glycation
High blood sugar, like the kind that develops after a bowl of oatmeal, triggers glycation, or modification of proteins by glucose (blood sugar). This is how cataracts, kidney disease, and atherosclerotic plaque develop. Small LDL is 8-fold more glycation prone than large LDL, providing a carbohydrate double-whammy.


Your glucose meter remains the single best tool to gauge the quality of your diet. Many people have horror stories of the shocking experiences they've had when they finally get around to checking their postprandial glucose.

Drama with the Dr. Oz Show

11. April 2010 William Davis (27)
A producer from the Dr. Oz show recently contacted my office. They asked whether we could supply them with a volunteer patient from either my practice or the Track Your Plaque program who would be willing to appear on the show and discuss heart disease prevention. They needed someone to commit within 24 hours.

Despite the short notice, we identified a volunteer. He flew to New York the following week where he was interviewed along with several other men and women, all of whom had heart disease (heart attacks, stents, etc.). However, as this young man is very slender and follows most of the Track Your Plaque principles (e.g., vitamin D and omega-3 fatty acid supplementation; no wheat, cornstarch, or sugars, no restriction of fat, etc.), he apparently received less attention than the overweight, I-know-nothing-about-diet interviewees.

Then there was an odd turn of events: Dr. Dean Ornish, apparently a friend of Dr. Oz, will be providing the dietary counseling. The producer had made no mention of Dr. Ornish.

Now that's an odd collision of philosophies: Our Track Your Plaque version of low-carb with the guru of low-fat, Dr. Ornish.

The following week, Dr. Ornish called me and graciously asked whether I was okay with this. I'm not sure just how much he knew about the philosophy I advocate, nor how much I have bashed his program as a destructive approach to diet, nor whether he knew that I gained 30 lbs on the Ornish diet, along with a drop in HDL to 27 mg/dl, increased triglycerides to 350 mg/dl, and type II diabetes that I've talked about on this blog and the Track Your Plaque book and website. I suspect he knew little to none of this.

Anyway, I tried to diplomatically explain that my patient's cause for coronary plaque was small LDL particles that he expressed despite his very slender build, likely from excessive carbohydrates, controlled with carbohydrate restriction. Dr. Ornish maintained his usual arguments: Grains are good, provided they are whole grains, heart disease is "reversed" with his diet program, etc. (I didn't want to challenge him in a phone call and tell him that he never actually reversed coronary plaque, but just reversed endothelial dysfunction. But, as Dr. Ornish is not a cardiologist, I wasn't sure how far his understanding of these issues went.)

We agreed to disagree. This leaves my poor patient in an odd position: Being asked by Dr. Ornish and the Dr. Oz show to follow a low-fat program for the sake of entertainment, or adhering to the advice we follow that has so far served him well, given his small LDL particle size tendencies.

We'll see where this little drama leads.

Response from Nature Made

10. April 2010 William Davis (31)
Here's the response from Nature Made when I emailed them about my concern that there appears to be no vitamin D in their vitamin D gelcaps.

It is the usually CYA corporate-speak that says nothing. The grammatical errors make it clear that this was a "canned" response.



Date: April 9, 2010
From: Marissa Reyes, Consumer Affairs Department
Subject: Reference #346236

Dear William Davis, MD:

We recently received your e-mail regarding Nature Made products. We regret to
hear that the quality standards of our company. [?]

Our company is called Pharmavite, and we manufacture Nature Made nutritional
supplements. We have been in business since 1971. We are committed to quality
control, and have very high quality standards. Our Quality Control personnel
sample and test all raw materials as they enter our plant, and again assay the
finished product, before final packaging.

Dietary Supplements are regulated under the FDA through DSHEA (Dietary
Supplement Health & Education Act of 1994). The United States Pharmacopoeia
(USP) establishes standards for the composition of drugs and nutritional
supplements. This voluntary non governmental organization was set up in 1820
and has officially been recognized by federal law since 1906. Standards
established by USP for products are legally enforceable by the FDA. At
Pharmavite we participate in the USP Dietary Supplement Verification Program
(DSVP). Many of our products have earned the DSVP seal and additional products
are currently being evaluated. Our DSVP certified products will have the DSVP
seal on the product label.

Our Nature Made Vitamin D 400 IU tablets have been reviewed by the USP and bears
the DSVP symbol on the label. Although the USP has not reviewed all of the
Nature Made Vitamin D supplements, all of our products go through the same
rigorous quality testing at Pharmavite. The products which have earned the seal
help us to demonstrate the high quality of our products.

We would like to look into the product(s) your patients have been using. If you

Patients who come to the office do not provide me with the bottles nor lot numbers. In past, when I've gone to the trouble of doing this (with other companies, not Nature Made), it has come to nothing helpful. The information gets passed on to the company and we hear nothing and never learn if there was a problem, or receive some more corporate-speak letter saying everything was fine. This is obviously a liability-avoidance tactic: Admitting that something was wrong would open them up to legal risk. So, frankly, I can't be bothered.

So we are left with the unsatisfying experience of relying on street-level experiences.

For now, my advice: Avoid Nature Made vitamin D. Too many people have had blood tests demonstrating that they are not obtaining any vitamin D.

By the way, the Nature Made brand of fish oil is among the very few problem brands of fish oil we've encountered. Fish oil should be only mildly fish in smell and generally should not cause stomach upset and excessive belching if properly purified. Nature Made is excessively fishy when you smell it, suggesting oxidation. We've had repeated (dozens) of patients who have experienced difficulties with this brand. Rather than dealing with the frustrating gobbledy-gook of this company, just avoid their products.

What to Eat: The diet is defined by small LDL

9. April 2010 William Davis (15)
I approach diet from the perspective of small LDL particles.

Small LDL particles have exploded in frequency and severity in Americans. It is not at all uncommon to see 70% or more small LDL particles (i.e., 70% of total LDL particle number or Apo B) on lipoprotein testing. (I saw two people today who began with over 95% small LDL.)

Small LDL particles are:
--More likely to persist in the bloodstream longer than large LDL particles.
--More likely to adhere to components of atherosclerotic plaque.
--More likely to gain entry to plaque.
--More likely to be taken up by inflammatory white blood cells which, in turn, become the mast cells that fill coronary plaque.
--More likely to be oxidized.
--More likely to be glycated (8-fold more likely than large)

To add insult to injury, foods that trigger small LDL formation--i.e., carbohydrates--also cause high postprandial blood sugars. High postprandial blood sugars, in turn, glycate small LDL. That combination of events accelerates 1) plaque growth, 2) plaque instability, and 3) aging.

So carbohydrates trigger this sequence, carbohydrates of all stripes and colors. Not just "white" carbohydrates, but ALL carbohydrates. It's all a matter of degree and quantity. So, yes, even quinoa, bulghur, and sorghum trigger this process. I've only recently appreciated just how bad oats and oatmeal are in this regard--really bad.

Foods that trigger small LDL also trigger higher blood sugars; foods that trigger higher blood sugars also trigger small LDL. Small LDL and blood sugar are two different things, but they track each other very closely.

So, in the Track Your Plaque approach to diet, we craft diet based on these simple principles:

1) Eliminate wheat, cornstarch, and sugars--These are the most flagrant triggers of small LDL, blood sugar, and, therefore, LDL glycation.
2) The inclusion of other carbohydrates, such as oatmeal, quinoa, rye, etc. depends on individual sensitivity. Individual sensitivity is best gauged by assessing one-hour postprandial glucose.

Stay tuned for more in this series. Also, Track Your Plaque Members: We will be having an in-depth webinar detailing more on thees principles in the next couple of weeks.

Is it or isn't it vitamin D?

7. April 2010 William Davis (63)
Jackie takes 10,000 units of vitamin D(3) per day as a gelcap.

Her starting 25-hydroxy vitamin D blood level was 18.1 ng/ml. Severe deficiency, no surprise.

On her 10,000 units per day, Vitamin Shoppe brand, her 25-hydroxy vitamin D level was 76.2 ng/ml--perfect. It stayed in this range for about two years.

She then changed to the Nature Made brand gelcaps she picked up at Walgreen's. Repeat 25-hydroxy vitamin D level: 23 ng/ml.

This has now happened with five different people, all taking the Nature Made brand.

If you are taking this brand of vitamin D, please be on the alert. You might consider a 25-hydroxy vitamin D blood level to be sure it actually has the vitamin D it's supposed to have.

Or, change brands.

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

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.
