Fish oil: The natural triglyceride form is better

2. February 2011 William Davis (43)
If you have a choice, the triglyceride form of fish oil is preferable. The triglyceride form, i.e., 3 omega-3 fatty acids on a glycerol "backbone," is the form found in the body of fish that protects them from cold temperatures (i.e., they remain liquid at low ambient temperatures).

Most fish oils on the market are the ethyl ester form. This means that the omega-3 fatty acids have been removed from the glycerol backbone; the fatty acids are then reacted with ethanol to form the ethyl ester.

If the form is not specified on your fish oil bottle, it is likely ethyl ester, since the triglyceride form is more costly to process and most manufacturers therefore boast about it. Also, prescription Lovaza--nearly 20 times more costly than the most expensive fish oil triglyceride liquid on a milligram for milligram basis--is the ethyl ester form. That's not even factoring in reduced absorption of ethyl esters compared to triglyceride forms. Remember: FDA approval is not necessarily a stamp of superiority. It just means somebody had the money and ambition to pursue FDA approval. Period.

Taking any kind of fish oil, provided it is not overly oxidized (and thereby yields a smelly fish odor), is better than taking none at all. All fish oil will reduce triglycerides, accelerate clearance of postprandial (after-eating) lipoprotein byproducts of a meal (via activation of lipoprotein lipase), enhance endothelial responsiveness, reduce small LDL particles, and provide a physical stabilizing effect on atherosclerotic plaque.

But if you desire enhanced absorption and potentially lower dose to achieve equivalent RBC omega-3 levels, then triglyceride forms are better.

Here are cut-and-pasted abstracts of two of the studies comparing forms of fish oil.

Bioavailability of marine n-3 fatty acid formulations.

Dyerberg J, Madsen P, Moller JM et al. 
Department of Human Nutrition, Faculty of Life Sciences, University of Copenhagen, Copenhagen, Denmark.

Abstract

The use of marine n-3 polyunsaturated fatty acids (n-3 PUFA) as supplements has prompted the development of concentrated formulations to overcome compliance problems. The present study compares three concentrated preparations - ethyl esters, free fatty acids and re-esterified triglycerides - with placebo oil in a double-blinded design, and with fish body oil and cod liver oil in single-blinded arms. Seventy-two volunteers were given approximately 3.3g of eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) daily for 2 weeks. Increases in absolute amounts of EPA and DHA in fasting serum triglycerides, cholesterol esters and phospholipids were examined. Bioavailability of EPA+DHA from re-esterified triglycerides was superior (124%) compared with natural fish oil, whereas the bioavailability from ethyl esters was inferior (73%). Free fatty acid bioavailability (91%) did not differ significantly from natural triglycerides. The stereochemistry of fatty acid in acylglycerols did not influence the bioavailability of EPA and DHA.

Enhanced increase of omega-3 index in response to long-term n-3 fatty acid supplementation from triacylglycerides versus ethyl esters.

Neubronner J, Schuchardt JP, Kressel G et al. 
Institute of Food Science and Human Nutrition, Leibniz Universität Hannover, Am Kleinen Felde 30, Hannover, Germany.

Abstract

There is a debate currently about whether different chemical forms of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are absorbed in an identical way. The objective of this study was to investigate the response of the omega-3 index, the percentage of EPA+DHA in red blood cell membranes, to supplementation with two different omega-3 fatty acid (n-3 FA) formulations in humans. The study was conducted as a double-blinded placebo-controlled trial. A total of 150 volunteers was randomly assigned to one of the three groups: (1) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as reesterified triacylglycerides (rTAG group); (2) corn oil (placebo group) or (3) fish oil concentrate with EPA+DHA (1.01?g+0.67?g) given as ethyl ester (EE group). Volunteers consumed four gelatine-coated soft capsules daily over a period of six months. The omega-3 index was determined at baseline (t(0)) after three months (t(3)) and at the end of the intervention period (t(6)). The omega-3 index increased significantly in both groups treated with n-3 FAs from baseline to t(3) and t(6) (P < 0.001). The omega-3 index increased to a greater extent in the rTAG group than in the EE group (t(3): 186 versus 161% (P < 0.001); t(6): 197 versus 171% (P < 0.01)). Conclusion: A six-month supplementation of identical doses of EPA+DHA led to a faster and higher increase in the omega-3 index when consumed as triacylglycerides than when consumed as ethyl esters.

Diarrhea, asthma, arthritis--What is your wheat re-exposure syndrome?

30. January 2011 William Davis (52)
Have you experienced a wheat re-exposure syndrome?

As I recently discussed, gastrointestinal distress--cramps, gas, diarrhea--is the most common "syndrome" that results from re-exposure to wheat after a period of elimination.

Others experience asthma, sinus congestion and infections, mental "fogginess" and difficulty concentrating, or joint pains and/or overt swelling.

Still others say there is no such thing.

Let's take a poll and find out what readers say.

Marathoners, triathletes, and heart disease

30. January 2011 William Davis (0)
Curious thing: People with lipoprotein(a) gravitate towards elite levels of exercise.

I tell my lipoprotein(a) patients that, if they want to see a lot of other people with lipoprotein(a), go to a marathon or triathlon.

This effect applies more to males than to females, just as the fascination with numbers seems to be confined to men, too. That's why I've posted in past about the "prototypical" lipoprotein(a) male.

I believe this is a big part, perhaps the only, reason why there seems to be a modest increased risk for cardiovascular events despite high exercise levels in marathoners. It has nothing to do with the exercise itself; it has to do with the kind of people who choose to exercise at this level.

The best fish oil

29. January 2011 William Davis (30)
The best fish oils available are the liquid forms. Contrary to many people's expectations, the best liquid fish oils have no fishy odor or taste.

I use a lot of liquid fish oils because of the higher doses we use in the Track Your Plaque program, as well as our strategy of high-dose fish oil to reduce lipoprotein(a). Women, in particular, don't like taking the oodles of capsules required to achieve the higher doses we need. So the ladies really like the liquid forms.

The best liquid fish oils are non-fishy, highly-concentrated, and come in the better absorbed triglyceride form. Many capsules, including prescription Lovaza, are the less well-absorbed ethyl ester form. Several studies, such as this one, have now demonstrated that the naturally-occurring triglyceride form yields higher blood (RBC) levels of omega-3 fatty acids, likely due to more efficient digestion via pancreatic lipase.

While there are many good forms of fish oil and only a few bad, these are the best of the best:

Pharmax
The Pharmax Finest Pure Fish Oil with Essential Oil of Orange contains 1800 mg EPA + DHA per teaspoon. This is the preparation I've been taking.

Nordic Naturals
The Nordic Naturals lemon-flavored ProOmega Liquid contains 2752 mg EPA + DHA per teaspoon, the most concentrated of any fish oil I've seen.

(This list is not exclusive. These are just two brands I've used extensively with good results.)

These highly-concentrated, triglyceride forms are more expensive, due to their concentrated nature. 1 teaspoon Pharmax fish oil, for example, provides an equivalent quantity of omega-3 fatty acids as 6 standard fish oil capsules on a milligram for milligram basis, but more like 8 to 9 capsules when absorption efficiency is factored in. The triglyceride form is also more laborious to manufacture. On our Track Your Plaque Marketplace, our Pharmax 500 ml runs $58.95 list. (500 ml provides 100 teaspoons or 600-capsule equivalent.)

Note that, minus the protection of the capsule, liquid fish oils will oxidize if not refrigerated. So be sure to keep your liquid fish oil in the fridge.

What do Salmonella, E coli, and bread have in common?

28. January 2011 William Davis (22)
Say you happen to eat some chicken fingers contaminated with bacteria because the 19-year old kid behind the counter failed to wash his hands after using the toilet, or because the kitchen is poorly managed with unwashed counters and cutting boards, or because the food is undercooked. You get a bout of diarrhea and cramps, along with a desire to banish chicken from your life.

Here's yet another odd wheat phenomenon: About 30% of people who eliminate wheat from their lives experience an acute food poisoning-like effect on re-exposure. You've been wheat-free for, say, 6 months. You've lost 25 lbs from your wheat belly, you've regained energy, joints feel better. You go to an office party where they're serving some really yummy looking bruschetta. Surely a couple won't hurt! Within a hour, you're getting that awful rumbling and unease that precede the explosion.

The majority of people who experience a wheat re-exposure syndrome will have diarrhea and cramps that can last from hours to days, similar to food poisoning. (Why? Why would a common food trigger a food poisoning-like effect? It happens too fast to attribute to inflammation.) Others experience asthma attacks, joint pains that last 48 hours to a week, mental fogginess, emotional distress, even rage (in males).

Wheat re-exposure in the susceptible provides a tidy demonstration of the effects of this peculiar product of genetic research. So if you are wheat-free but entertain an occasional indulgence, don't be surprised if you have to make a beeline to the toilet.

The world of intermediate carbohydrates

28. January 2011 William Davis (0)
There are clear-cut bad carbohydrates: wheat, oats, cornstarch, and sucrose. (Fructose, too, but in a class of bad all its own.)

Wheat: The worst. Not only does wheat flour increase blood sugar higher than nearly all other carbohydrates, it invites celiac disease, neurologic impairment, mental and emotional effects, addictive (i.e., exorphin) effects, asthma, irritable bowel syndrome, acid reflux, sleepiness, sleep disruption, arthritis . . . just to name a few.

Oats: Yeah, yeah, I know: "Lowers cholesterol." But nobody told you that oats, including slow-cooked oatmeal, causes blood sugar to skyrocket.

Cornstarch: Like wheat, cornstarch flagrantly increases blood sugar.It also stimulates appetite. That's why food manufacturers put it in everything from soups to frozen dinners.

Sucrose: Not only does sucrose create a desire for more food, it is also 50% fructose, the peculiar sugar that makes us fat, increases small LDL particles, increases triglycerides, slows the metabolism of other foods, encourages diabetes, and causes more glycation than any other sugar.

But there are a large world of "other" natural carbohydrates that don't fall into the really bad category. This includes starchy beans like black, kidney, and pinto; rices such as white, brown, and wild; potatoes, including white, red, sweet, and yams; and fruits. It includes "alternative" grains like quinoa, spelt, triticale, amaranth, and barley.

For lack of a better term, I call these "intermediate" carbohydrates. They are not as bad as wheat, etc., but nor are they good. They will still increase blood glucose, small LDL, triglycerides, etc., just not as much as the worst carbohydrates.

The difference is relative. Say we compare the one-hour blood glucose effects of 1 cup of wheat flour product vs. one cup of quinoa. Typical blood sugar after wheat product: 180 mg/dl. Typical blood sugar after quinoa: 160 mg/dl--better but still pretty bad.

Some people are so carb-sensitive that they should avoid even these so-called intermediate carbohydrates. Others can have small indulgences, e.g., 1/2 cup, and not generate high blood sugars.

Heroin, Oxycontin, and a whole wheat bagel

25. January 2011 William Davis (27)
For a substantial proportion of people who remove wheat from their diet, there is a distinct and unpleasant withdrawal syndrome. Here are the comments of Heart Scan Blog reader, Scott, from Texas:

Hello Dr. Davis,

I've been experimenting with diet, converging upon a Paleo type diet, but I keep running into problems. I have isolated the problem to cutting out wheat.

Sugar, rice, fruit, corn, potatoes, etc. are relatively ok to add or remove from the diet, but cutting out wheat in particular brings on a moderate headache with heavy fatigue all day long. This resembles the wheat withdrawal symptoms I found on your blog. As I write this, I'm on day 8 of wheat-free. I consume a fair variety of meat and veggies each day with a moderate amount of white rice for carbs. Perhaps a bowl of corn flakes with milk and half a bar of dark chocolate a day. I've learned from experience over the past 5 months or so that none of these foods affect the withdrawal. It's purely wheat.

My question is, what is the range of times for withdrawal symptoms that you've heard from different people? Has there been anyone who never recovered from the wheat withdrawal symptoms even after many months?

It's very tough to get work done like this, and even though my body and head feel much healthier in general, my sinuses have cleared, don't have to take a big nap after I eat, etc., I don't want to go down a path where this is the way things are going to be forever. 


People who have never experienced wheat withdrawal pooh-pooh the effect. But, for about 30% of people, wheat withdrawal is a real, palpable, and sometimes incapacitating experience.

Beyond removing an exceptionally digestible carbohydrate that yields blood sugar rises higher than nearly any other known food (due to the unique amylopectin structure of wheat-derived carbohydrate), wheat withdrawal is a form of opiate withdrawal, somewhat like stopping heroin, Oxycontin, and other opiates. Stop eating whole wheat toast for breakfast, whole grain sandwiches for lunch, or whole grain pasta for dinner, and the flow of exorphins, i.e., exogenous morphine-like compounds, stops. You experience dysphoria (sadness, unhappiness), mental "fog," inability to concentrate, fatigue, and decreased capacity to exercise. It is milder than withdrawal from prescription opiates. Unlike withdrawal from more powerful opiates like heroine, there are, thankfully, no seizures or hallucinations. There are also no deaths.

In my experience, most people get through with wheat withdrawal in about 5 days. An occasional person will struggle for as long as 4 weeks. Thankfully for Scott, I've never seen it last longer than 4 weeks. (Interestingly, people who survive the withdrawal syndrome are often prone to a peculiar re-exposure phenomenon that I will discuss in future, i.e., they get sick upon re-exposure.)

The modern dwarf mutant variant of Triticum aestivum (that our USDA urges us to eat more of) contains greater proportions of gluten proteins compared to wheat pre-1970; glutens are the source of wheat-derived exorphins.

Incidentally, a drug company should be releasing a drug in the next year that will contain naltrexone, an oral opiate blocking drug, for a weight loss indication. They claim it is a blocker of the "mesolimbic reward system." I say it's a blocker of wheat exorphins.

The five most powerful heart disease prevention strategies

24. January 2011 William Davis (39)
You've seen such lists before: 5 steps to prevent heart disease or some such thing. These lists usually say things like "cut your saturated fat," eat a "balanced diet" (whatever the heck that means), exercise, and don't smoke.

I would offer a different list. You already know that smoking is a supremely idiotic habit, so I won't repeat that. Here are the 5 most important strategies I know of that help you prevent heart disease and heart attack:

1) Eliminate wheat from the diet--Provided you don't do something stupid, like allow M&M's, Coca Cola, and corn chips to dominate your diet, elimination of wheat is an enormously effective means to reduce small LDL particles, reduce triglycerides, increase HDL, reduce inflammatory measures like c-reactive protein, lose weight (inflammation-driving visceral fat), reduce blood sugar, and reduce blood pressure. I know of no other single dietary strategy that packs as much punch. This has become even more true over the past 20 years, ever since the dwarf variant of modern wheat has come to dominate.

2) Achieve a desirable 25-hydroxy vitamin D level--Contrary to the inane comments of the Institute of Medicine, vitamin D supplementation increases HDL, reduces small LDL, normalizes insulin and reduces blood sugar, reduces blood pressure, and exerts potent anti-inflammatory effects on c-reactive protein, matrix metalloproteinase, and other inflammmatory mediators. While we also have drugs that mimic some of these effects, vitamin D does so without side-effects.

3) Supplement omega-3 fatty acids from fish oil--Omega-3 fatty acids reduce triglycerides, accelerate postprandial (after-meal) clearance of lipoprotein byproducts like chylomicron remnants, and have a physical stabilizing effect on atherosclerotic plaque.

4) Normalize thyroid function--Start with obtaining sufficient iodine. Iodine is not optional; it is an essential trace mineral to maintain normal thyroid function, protect the thyroid from the hundreds of thyroid disrupters in our environment (e.g., perchlorates from fertilizer residues in produce), as well as other functions such as anti-bacterial effects. Thyroid dysfunction is epidemic; correction of subtle degrees of hypothyroidism reduces LDL, reduces triglycerides, reduces small LDL, facilitates weight loss, reduces blood pressure, normalizes endothelial responses, and reduces oxidized LDL particles.

5) Make exercise fun--Not just exercise for the sake of exercise, but physical activity or exercise for the sake of having a good time. It's the difference between resigning yourself to 30 minutes of torture and boredom on the treadmill versus engaging in an activity you enjoy and look forward to: go dancing, walk with a friend, organize a paintball tournament outdoors, Zumba class, plant a new garden, etc. It's a distinction that spells the difference between finding every excuse not to do it, compared to making time for it because you enjoy it.

Note what is not on the list: cut your fat, eat more "healthy whole grains," take a cholesterol drug, take aspirin. That's the list you'd follow if you feel your hospital needs your $100,000 contribution, otherwise known as coronary bypass surgery.

Topping up your vitamin D tank

22. January 2011 William Davis (17)
Now that my vitamin D replacement experience dates back nearly 5 years, I've been witnessing an unusual phenomenon:

The longer you take vitamin D, the less you need.

Let me explain. You take 10,000 units D3 in gelcap form. 25-hydroxy vitamin D levels, checked every 6 months, have remained consistently between 60 and 70 ng/ml. Three years into your vitamin D experience and 25-hydroxy vitamin D level rises to 98 ng/ml--an apparent need for less vitamin D.

So we cut your intake from 10,000 units per day to 8000 units per day. Another 25-hydroxy vitamin D level 6 months later: 94 ng/ml. We cut dose again to 6000 units, followed by another 25-hydroxy vitamin D level of 66 ng/ml.

This has now happened in approximately 20% of the people who have been taking vitamin D for 3 or more years. I know of no formal analysis of this effect, what I call the "topping up" phenomenon. Reasoned simply, it seems to me that, once your vitamin D "tank" is topped up (i.e., tissue stores have been replenished), it requires less to keep it full.

No one has experienced any adverse consequence of this topping up effect though it has potential for some people to develop toxic levels if 25-hydroxy vitamin D levels are not monitored long-term. In my office, I measure 25-hydroxy vitamin D levels every 6 months.

It means that long-term monitoring of 25-hydroxy vitamin D is crucial to maintain favorable and safe levels.

Thirteen catheterizations later

21. January 2011 William Davis (16)
When I first met her, Janet couldn't stop sobbing. She'd just been through her 10th heart catheterization in two years.

It started with chest pains at age 56, prompting her first heart catheterization that uncovered severe atherosclerotic blockages in all three coronary arteries. Her cardiologist advised a bypass operation.

Six months after the bypass operation, Janet was back with more chest pains, just as bad as before. Another heart catherization showed that two of the three bypass grafts had failed. The third bypass graft contained a severe blockage that required a stent, along with multiple stents in the two now unbypassed arteries.

In the ensuing 18 months, Janet returned for 8 additional catheterizations, each time leaving the hospital with one or more stents.

Janet's doctor was puzzled as to why her disease was progressing so aggressively despite Lipitor and the low-fat diet provided by the hospital dietitian. So he had Janet undergo lipoprotein testing (NMR):

LDL particle number: 3363 nmol/L
Small LDL particle number: 2865 nmol/L
HDL cholesterol: 32 mg/dl
Triglycerides: 344 mg/dl
Fasting blood glucose 118 mg/dl
HbA1c 5.8%

Unfortunately, Janet's doctor didn't understand what these values meant. He pretty much threw his arms up in frustration. That's when I met Janet.

From her lipoprotein panel and other values, it was clear to me that Janet was miserably carbohydrate-sensitive and carbohydrate-indulgent, as demonstrated by the extravagant quantity (2865 nmol/L) and proportion (2865/3363, or 85%) of small LDL, the form of LDL particles created by carbohydrate exposure. Janet struggled with depression over the years and had been using carbohydrate foods as "comfort" foods, often resorting to cookies, pies, cakes, breads, and other wheat-containing foods for emotional solace.

It took a bit of persuasion to convince Janet that it was low-fat, "healthy whole grains," as well as comfort foods, that had led her down this path. I also helped Janet correct her severe vitamin D deficiency, mild thyroid dysfunction, and lack of omega-3 fatty acids.

Since meeting Janet and instituting her new prevention program, she has undergone three additional catheterizations (performed by another cardiologist), all performed for chest pain symptoms that struck during periods of emotional stress. All showed . . . no significant blockage. (Apparently, the repeated "need" for stents triggered a Pavlovian response: chest pain = "need" for yet more stents.)

In short, correction of the causes of coronary atherosclerotic plaque--small LDL, vitamin D deficiency, omega-3 fatty acid deficiency, and thyroid dysfunction--and Janet's disease essentially ground to a halt.

Imagine, instead, that Janet had undergone 1) a heart scan to identify hidden coronary plaque 5-10 years before her first heart procedure, then 2) corrected the causes before they triggered symptoms and posed danger. She might have been spared an extraordinary amount of life crises, hospital procedures, expense (nearly $1 million), and emotional suffering.
Have some more

Have some more

7. April 2011 William Davis (37)
Wheat, via exorphin effects, is an appetite stimulant. Eat a whole wheat bagel or bran muffin, you want another. You also want more of other foods. You also want something to eat every two hours due to widely-swinging insulin-glucose responses: blood sugar high followed by a sharp downturn that triggers a powerful impulse to eat (thus the cravings for a snack at 9 and 11 a.m. after a 7 a.m. breakfast).

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

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

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

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

    The reduced appetite after wheat withdrawal is exactly what I'm experiencing. A very low carbs (and so very low wheat) diet is the first diet that I can stay on because I don't get hunger pangs. I'm down about 20 lbs. (10%) since finding this blog and going wheat-less.

    Hmmm... I've been wheat free (grain-free, actually) for almost 3 weeks now. I started off being mildly hungry all the time, and that has faded. I wonder if that's what you're talking about there!! Terrific!

    I started just before Christmas. The first week or so was unpleasant ... hungry, groggy ... wheat withdrawal. The "no hunger pangs" showed up after that and made it possible for me to stay on this diet. It's the first time I've been able to consistently lose weight.

    When I first went off wheat it took a good 3-4 weeks for the withdrawl to stop.  During that time I was ravenously hungry and ate constantly.  I know my body was just hoping I'd eventually eat some bread.  I gained probably 10 pounds, but it came back off (I don't have any other weight to lose).

    Was that a study you are referencing or clinical experience?  Would love to have more details.

    Biblical wheat and remote regional "landrace" wheat strains are not the same as tetra-ploid wheat we're sold. Tetraploid varieties have been grown for less than 500 years; and di-ploid varieties around for 500 to 1,000 years.

    Look, I'm glad that this works for some/lots of people - but I've been doing this since before Christmas, 4 months now, and I haven't lost a pound.  My status is a good deal worse in a number of subtle and not-so-subtle respects, and frankly nothing of substance has actually improved in any way.  Recommendations of iodine supplementation were an unqualified disaster.  And I effectively have nowhere to go, now -- I'm stuck with this mode, because I have every reason to believe that going back to grain in any degree will yield uncontrollable weight gain.  I'm really not trying to be negative, but the point  has to be made, amid all the rosy predictions of magic pounds disappearing (that's just calories-in-calories-out which is supposed to be BS, according to the new Received Wisdom, no?) that this regimen doesn't work for everyone.

    @Megaera

    I used to eat a lot of bread. For the first four months of my grain-free and carbs-from-veggie-only life and policing my blood sugar I gained about 10lbs. My NMR profile got significantly worse, too. Dr Davis checked my APOE and it was type 4, so he told me to limit fats and changed my medications. In addition, I stopped being a vegetarian and increased the amount of lean proteins in my diet. I also changed my exercise routine according to slow-burn. Four months later - 14 lbs have been lost and NMR profile improved drastically.

    I am saying it, because there is a happy path of losing weight when you stop eating wheat, but certain people may need to make an additional effort. So you need to look further.

    Japanese children (290) aged 5 - 18 had MRI of brain to see if breakfast centered on white bread vs. white rice differ. The study adjusted for confounding factors.

    The older white rice breakfasters showed a larger grey matter in relation to cranium volume; in some brain areas white bread eaters had more grey matter.In the youngest there was not a statistical differenece in grey matter volume between the groups.

    Rice breakfasters' MRI showed more grey matter in left superior temporal gyrus, left inferior temporal gyrus,right pre-central gyrus, left superior caudate  nuclei and the bilateral caudate nuclei. Caudate volume is associated with a subset of verbal IQ ( POI component); the rice breakfasters had higher POI scoring. And in addition they had higher IQ than the bread group; IQ is associated with prefrontal and orbito-facial corteces and the cingulate gyrus.

    Bread breakfasters MRI showed more grey matter in the postcentral gyrus, right precentral gyrus, right fronto- parietal orbit, and bilateral orbito-frontal corteces. Their MRI showed more white matter in
    the right pre-frontal gyrus  and post-central guyrus; otherwise the two diets showed no white matter % differences between the groups.

    My experience has been exactly like Steve's. Since going completely wheat-free (as well as ditching the sugar and most fruit), I'm down 15 lbs. and still losing. The best part of all is that my hypoglycemia symptoms have completely disappeared, my energy is through the roof, and I no longer get uncontrollable hunger pangs.

  • Dr. William Davis

    4/8/2011 1:01:57 AM |

    As Steve and 1st Anonymous point out, this approach can work for many, if not most, people with extravagant weight loss and health benefits.

    However, as the frustration expressed by Meg suggests, there may be confounding factors. As Gene points out, apo E4, for instance, can modify the response. But this was not the focus of the post.

    This is a blog. Each post makes a point. Don't mistake this for a one-on-one healthcare encounter.

    A few months ago, I read a post on this blog which suggested getting a BG meter in order to see what effect things like wheat had on BG. The results of my first meal (whole wheat pasta with red sauce, broccoli, and whole wheat toast) showed 183 at 1hr PP and 149 at 2hr! What was really surprising to me, however, was that despite the 2 hour number being as high as it was, I was still very hungry.

    Based on this and subsequent tests, along with increased awareness of satiety, I've made some pretty significant changes in the types of foods I eat. Mostly, I've cut back on all the grains (even "whole grain") and added fats (I no longer believe the "low fat" recommendations).

    The result is that in about 3 months I've lost roughly 15 lbs. (mostly in my belly), despite having no sense of being deprived. It doesn't hurt that my lipids have improved, as well (TC, LDL and trigs all lower).

    I had been skeptical of Dr. Davis's claims about wheat at first, but I am now convinced that for me at least, wheat is not my friend.

    What if that happens to me with prety much every thing. I want another almond, another egg, another piece of cheese, another wine, more chocolatte, another sushi, a bit more of meat....

    I started to cut down on my bread intake about 3 years ago and am now almost completely grain free (apart from accidental consumption). I have lost over 50lb and feel like a diifferent person.

    One of the biggest bonuses of cutting wheat from my diet is the improvement in my mood and temperament. I used to be quite a moody and slightly unpredictable type of personality, but now everything is calm and serene.

    Quite a few scientific papers show a connection between schizophrenia and cereal intake. http://healthydietsandscience.blogspot.com/search/label/Cereals%20and%20Schizophrenia

    This may help to explain the improvement in my personality.

    I've been mostly wheat-free for over a year, and have lost exactly zero pounds. I still don't eat it, since I believe there are a lot of benefits to leaving it out (all my blood-work #'s were fine before, but improved a bit more after awhile of high-fat/low carb). The biggest improvement I've seen is in my mood -- no more depression. However, I'm still 100 lbs overweight. Frown

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


    I would be interested in one study demonstrating that just cutting wheat from the diet resulted in 350-400 cal/day spontaneous reductions in intake.  Preferably controlled for protein content by substituting other carbs for normal wheat content.  

    The VLC diet studies don't count as too many variables are changed there to attribute most, if even any, of the decreased intake to reductions in wheat intake.

    If wheat is addictive, and whole wheat supposedly contains more addictive substances, why don't people gravitate towards whole wheat pasta and bread and binge on
    those?

    CarbSane-

    You stated "The VLC diet studies don't count as too many variables are changed there to attribute most, if even any, of the decreased intake to reductions in wheat intake."

    Same could be said for the studies that cholesterol and fat are the sole reasons for our obesity, diabetes, heart disease, etc- yes?

    I also don't buy your suggestion that people don't binge on whole wheat containing foods as I've seen it countless times at bagel shops, healthy Asian noodle bowl places, pizzerias, etc. People trying to eat "Healthy" often over indulge on "healthy" pizzas, bagels, breads and pasts all while thinking they are doing eating exactly what the AHA recommends. Something that is more than likely silently killing them.

    I've done all this before and all it got me was a plethora of trips to a cardiologist, anxiety, depression, bloating and countless Rx pills that did absolutely nothing. And I'm not an unhealthy guy by any means.

    You may feel Dr. Davis' posts are all anecdotal and that's fine. His new Track Your Plaque book has all the evidence and studies I need to support his claims and it was the anecdotal evidence that he posts that spoke volumes to me. It was the first place I found that explained exactly what I was going thru (30 years old, extremely hypertensive, depressed, slightly overweight and angry with atherosclerosis that seriously a 30 year old should not be suffering from). From that point on I've read his book, followed his plan and have replaced all my worthless Rx's for a daily dose of VD3, Omega3 and steer clear of "Healthy" grains... and I couldn't be happier.

    Of course this is my own "anecdotal" experience, that four of my previous cardiologists couldn't achieve...

    In posts above I didn’t make clear that I am actively “dieting” as in “trying to lose weight”.

    My diet: Two Atkins shakes for breakfast with vitamins and two more for lunch. An Atkins shake for snacks, as needed. Dinner is a leafy greens salad with vinaigrette and maybe nuts, peppers, tomatoes, cheese, minced garlic plus a meat portion and sometimes a low-carb vegetable. A 30 minute after-dinner walk with my dog most  evenings. A 15 minute walk/run some mornings before my weigh-in.

    I believe the only reason I can stay on this tough diet is the “no hunger pangs” effect that I get with very-low-carbs. For example, I can have the Atkins shakes for breakfast and easily go until lunch with no cravings. To accelerate weight loss, I can even skip breakfast – no hunger pangs means I can go from dinner to lunch without cravings – I’m hungry but I can do it – I’ve done it every day this week.

    I’m about 5’8”. I found this blog on Dec. 17th and I weighed 204 lbs. On Jan. 29th I weighed 189. Today, April 8th, I weighed in at 179.8! I hadn’t been in the 190s in years. The 180s? The 170s? They were just dreams to me.

    I have gone off the diet; typically after multiple social events in a row. Example -- alumni social Thursday eve, extended-family dinner at a restaurant Friday eve, sports event Saturday, why-not-keep-eating Sunday. Then, I want to keep losing weight so I get back on the diet. I go through wheat-withdrawal again but now I know it’s just a temporary phase and that helps me get through it. It takes about 10 days to get back to where I was and then I keep dieting.

    Disclaimers – On a tough diet like this I am weaker than normal but I can function and I put up with it because, after my initial success, I see this works & I want to lose the weight. I have a desk job so I can probably better handle the reduced energy levels than someone with a more active job. My family is supportive and we eat dinners that work with the diet. So I have intangible factors helping me.

    One definition of hack is “a clever solution to a tricky problem”. To me, very-low-carbs is an empowering “hack” of my metabolism that lets me control my weight. Hallelujah!

    A single variety of modern tetra-ploid wheat has 100s of different gluten proteins. This equates to 10s of thousands of variations of peptide sequences one can ingest from wheat.

    The molecules formed depend on how trans-amin-dation (cross linking proteins) binds the free residues of glutamine. This potential bond is genetic for each strain of wheat, since involves the positioning of Carbon terminals (located on any of those peptides, as a proline residue). Tetra-ploid wheat has many unique proline residues that cross-link (ex: alpha gliadin) in a way that can resist our digestion.

    Plasticity is a term used to describe the human brains ongoing adaptability. The nerve axons are in a outer (extra-cellular) matrix of gluco-proteins; this includes the proteo-glycan chondroitin sulfate ( glycan = poly-saccharides & oligo-saccharides; hence "glyc-").

    Chondroitin sulfate's residue (wing) of N-acetyl-galactos-amine provide a place for lectins to bind to (ex: lectins most infamous  trans-amididation incarnation is the gliadin molecule, a type of glyco-protein). Thus different glyco-proteins, with unique derivative glycos-amino-glycan molecular chains are going to affect brain neurons differently.

    Anti-bodies for uOR (natural opiod receptor)detected in circulation are indicative of a reaction to some lectin. This means a lectin is binding to the uOR; Doc calls this an "exorphin effect" with one end result being appetite stimulation.

    Neo-striata cells in the brain work off of input from the cortex; the neo-striatum has a part called the matrix (note: here matrix is a brain structure & not to be confused with terms like extra-cellular matrix) and another part called the striosome. The matrix neo-striata gets input from the pre-frontal brain and senori-motor regions; while the striosome input is from pre-limbic, infra-limbic and pre-motor corteces.

    The matrix neo-striata neuro-chemistry is  integral to behavior involved in self-initiated action, goal directed behavior, sensory integration and motor programs. During post-natal (growing child) brain development the striosome neo-striatum cells have a high degree of involvement with glyco-proteins; which may partly explain the Japan school children brain development differences due to breakfast of rice vs. bread (detailed above).

    @Eric, I agree.  Don't know where I've claimed such.  Dr. Davis made a claim (and he preceded that with "When wheat products are removed from the diet--without calorie restriction, without counting fat or carbohydrate grams, no exercise program, no cleansing regimen, no skipping meals . . . nothing-").  Study?  One?  

    I'm just asking for a study that demonstrates this claim.  I don't refute that a good many people could benefit from avoiding wheat.

    My apologies CarbSane, I didn't mean for reply to come across as combative.

    Dr. Davis may have a study that he can refer you to.

    But it is a well known fact that foods that trigger a surge in blood sugar and after-meal crashing also lead to increased hunger more frequently.

    Foods that lead to the surge are carbs in (either healthy or processed) grain or sugar form.

    Sometimes all the anecdotal evidence should stand above the biased studies attempting to maintain the status quo. Just my .02

    I reduced my CHO intake about three years ago and lost about 8 pounds in the first three months.  At about the three month point, I removed wheat and all other grains from my diet.  I have lost no additional weight since I gave up wheat.  

    I would say that I have not reduced my caloric intake by 400 calories a day.

    @Eric, no apology necessary, I didn't take your post as combative at all.  I just find Dr.Davis making sensationalistic claims a matter of routine lately.  I do a lot of literature searching and I've not, to my memory, ever come across one study that just looked at eliminating wheat and intake.  I'd be curious to see the results of such a study done in a well controlled manner.

  • Dr. William Davis

    In response to several commenters:

    Citing studies in which calorie intake is reduced by strictly eliminating wheat while not imposing any other restrictions does not necessarily mean that this is the most healthy way to eat.

    In other words, if I eliminate wheat but replace lost calories with corn chips, jelly beans, and Coca Cola, then of course I will not lose weight nor obtain health benefits beyond elimination of gluten and other undesirable ingredients in wheat.

    A better approach would be to 1) eliminate wheat, then 2) reduce carbohydrates, especially cornstarch, oats, and sugar, then 3) eat other whole healthy foods.

    My point is that, sans wheat, the drive for consumption is diminished for many, though not all, people.

    MRI of adult brain while eating shows a response according to an individuals BMI variation. I had this as a well composed comment at WholeHealthSource, but can't retrace it; so, roughly, from my notes now.  

    High BMI individuals have more brain activity in the left posterior insula, supramarginal gyrus, para-central lobule and the cerebellum's uvula/declive/tonsil structures. Cerebellum response involves how one likes the looks/smell of food; more blood flowing in the cerebellum coincides with increased appetite.

    Low BMI individuals have more brain activity in the anterior insula, posterior hypothalamus, amygdala, thalamus, pons and mid-brain structures.

    The Vagus nerve (dorsal) leads from our "gut" up into the pons sub-nucleus of our brains dorsal raphe. In obese individuals this link shuts down when eating. Contrary to the obese, this link is open in lean individuals when they (non-obese) are eating.

    The Pons, which inputs into most of the other brain structures, shows more functioning with slower eating. In addition, stuffing with excess food in a meal slows the pons interaction with the brain.

    The Amygdala, part of our limbic system, sets the emotional response to things ingested. It gets plenty of neuro-signals from the gut, and is implicated in binge eating.

    The Posterior Insula recieves input from both the amygdala and hypothalamus (regulator of amount we ingest). In obese individuals both the posterior and middle insula trigger (on)into action when they see the meal; as contrasted to normal BMI individuals, where these brain structures remain unaffected when they (non-obese) see a meal.  

    In obese individuals there is comparatively more dopamine activity in the neurological circuits of the hypothalamus, amygdala, mid-brain and thalamus (arousal response). So, all in all, it seems quite possible Doc's nemesis (tetra-ploid wheat's molecules) can play antagonistic roles in the brain.

    But Dr. Davis, you said there are multiple studies demonstrating a similar drop in caloric intake from eliminating wheat "without calorie restriction, without counting fat or carbohydrate grams, no exercise program, no cleansing regimen, no skipping meals . . . nothing-"

    Are you walking that back?  Or do such studies exist.

    Hi CarbSane,
    Doc's rant is about the "undesireable ingredients"
    in modern wheat. If would you forgive me for sounding like a know-it-all, then, my comments show some brain responses that go beyond "x" number of calories, "x" amount of carbohydrates, "x" level of exercise and "x" amount of meals.

    It is modern wheat's assorted agglutin fractions, the way they bind glycans (like chitotriose, Beta-1-4-linked N-acetyl glucosamine) and how they cleave off "rogue" metabolites that has an effect on the brain cells. These metabolites have to get inside the brain cells cytoplasm by trans-duction; they are not ions.

    These "undesireable" cleaved metabolites have exposed glucosamine (GlcNAc) wings (residues) that bind to GLcNAc receptors on the cell; this fosters their trans-duction (carrying) past the cell membrane and any intervening endothelial (blood vessel wall) barriers.

    The "undesireable" metabolite then out binds Lysosome C; thus normal lysosomal "housekeeping" endo-cytosis (engulfing) action is inhibited from destroying (ie: no opportunity to hydrolyse apart bonds in the metabolite) that metabolite. This gives the metabolite the time to act like a Heat Shock Protein (ie: it has
    physically blocked that brain cell's usual heat shock protein ever since it locked onto that cell's GluNAc receptor); and thus, that "undesireable" metabolite can ferry (translocate) it's glycan/peptide right to the Endoplasmic Reticulum inside of that brain cell.

    Once the endoplasmic reticulum
    (in a brain cell) recieves an
    "undesireable" peptide/glycan complex it (endoplasmic reticulum) is not able to do a
    "normal" job with it; which job is to properly fold (ratchet into explicit configurations) the normal proteins the  brain cell passes to it (endoplasmic reticulum). Any alternate fold in a protein means it (protein)will react differently in the cascades it participates in.

    How this translates into each of the physical alterations in specific brain structures that I mentioned is beyond my understanding. This comment is to explain one of the ways those
    changes can get initiated in human brain cells by modern wheat; and also, to show our schooling on calories/carbs/ exercise/meals/cleansing misdirect us Doc insists he sees clinical results.

    Here is my wheat story. I have been "mostly" avoiding wheat for 3 years and when finally being diagnosed with Hashimoto's decided to go completely wheat free. My doctor suggested a gluten challenge for a definitive diagnoses of celiac or gluten intolerance.  Unfortunately, I agreed. Six weeks into the 3 month challenge I quit due to problems that began during the gluten challenge (joint pain, severe digestive distress, insomnia, adhesive capsulitis, nightsweats). Unfortunately the gluten caused some damage and I developed new food intolerances to dairy and nightshades, which have not resolved in 7 months of being grain free.

    Sorry this reply comes so late! I hope you see it. May I suggest that you try magnesium oil? It's a mixture of mag chloride and water that you apply to your skin. You may be mag deficient and, if so, that could explain why you're not losing weight.
