Unexpected effects of a wheat-free diet

Wheat elimination continues to yield explosive and unexpected health benefits.

I initially asked patients in the office to eliminate wheat because I wanted to help them reduce blood sugar and pre-diabetic tendencies.

A patient would come to the office, for example, with a blood sugar of 118 mg/dl (in the pre-diabetic range) and the other phenomena of pre-diabetes or metabolic syndrome (high blood pressure, high inflammation/c-reactive protein, low HDL, high triglycerides, small LDL), and the characteristic wheat belly. Eliminate wheat and, within three months, they lose 30 lbs, blood sugar drops to normal, blood pressure drops, triglycerides drop by several hundred milligrams, HDL goes up, small LDL plummets, c-reactive protein drops.

People also felt better, with flat tummies and more energy. But they also developed benefits I did not anticipate:

--Improved rheumatoid arthritis--I have seen this time and time again. Eliminate wheat and the painful thumbs, fingers, and other joints clear up dramatically. Many former rheumatoid sufferers people tell me that one cracker or pretzel will trigger a painful throbbing reminder that lasts a couple of hours.

--Improved ulcerative colitis--People incapacitated with pain, cramping, and diarrhea of ulcerative colitis (who are negative for the antibodies for celiac disease) can experience marked improvement. I've seen people be able to stop all their nasty colitis medications just by eliminating wheat.

--Reduction or elimination of irritable bowel syndrome

--Reduction or elimination of gastroesophageal reflux

--Better mood--Eliminating wheat makes you happier and experience more stable moods. Just as wheat is responsible for a subset of schizophrenia and bipolar illness (this is fact), and wheat elimination generates dramatic improvement, when you or I eliminate wheat, we also experience a "smoothing" of mood swings.

--Better libido--I'm not sure whether this is a consequence of losing a belly the size of a watermelon or improvement in sex hormones (esp. testosterone) or endothelial responses, but more interest in sex typically develops.

--Better complexion--I'm not entirely sure why, but various rashes will often dissipate, bags under the eyes are reduced, itching in funny places stops.


It's also peculiar how, after someone eliminates wheat for several months, re-exposure of an errant cracker or sandwich results in cramping and diarrhea in about 30% of people.

Obviously, people with celiac disease, who can even die of exposure to wheat, are even worse. What other common food do you know of that makes us sick so often, even occasionally with fatal outcome?

Is Lp(a) part of your legacy to your children?

If you have lipoprotein(a), Lp(a)--the most aggressive known cause of heart disease that no one has heard of--then you need to tell your children.

Lp(a) is a "cleanly" inherited genetic pattern: If either parent has it, there's a 50% chance that you have it. If you have it, then there's a 50% likelihood that each of your children has it. (Note that each child experiences a likelihood of 50%, not 50% of your children. This is because each child is conceived as an independent statistical event. So much for romance!)

The atherogenicity (plaque-causing potential) of Lp(a) also tends to get transmitted. In other words, if your Dad had a heart attack at age 50 due to Lp(a) and you share Lp(a), then you likely share a similar magnitude of risk as your Dad. If your Mom had Lp(a), though passed quietly at age 89 without any overt evidence of heart disease, then you are likely to share the relatively benign form of Lp(a).

For most of us with Lp(a), however, it is best to assume that it has at least some potential for causing heart disease, being the most aggressive cause known. (That is, until we have the ability in everyday clinical practice to characterize Lp(a) by assessing such factors as the size of the apoprotein(a) molecule, the number of kringle "repeats" on the tail, etc. Until then, we need to rely on the crude, though helpful, observation of family history.)

At what age should you inform your children? There's no hard-and-fast rule. However, I generally suggest to patients that they talk about Lp(a) with their children when they reach their 20s or 30s, old enough to begin to understand the implications and begin to think about adopting healthier lifestyles. Is treatment required at, say, age 35? That depends on the pattern of Lp(a)-related heart disease in the family: With exceptionally aggressive forms, it might be reasonable to begin treatment at this relatively early age.

Do "Heart Healthy" sterols cause heart disease?

The sterol question continues to pop up.

Sterols are an ingredient widely added by food manufacturers that allows a "heart healthy" claim, since sterols have been shown to reduce LDL cholesterol (at least transiently). HOWEVER, sterols have also been implicated in possibly increasing risk for heart disease. After all, people with the genetic condition called sitosterolemia absorb sterols into the blood and develop coronary heart disease in their teens and twenties. Those of us without sitosterolemia who increase sterol intake with sterol-enriched foods increase blood levels of sterols several-fold. Is this healthy, or does it contribute to coronary plaque as it does in people with sitosterolemia?

Below, I've reprinted a previous Heart Scan Blog post on sterols.


Sterols should be outlawed

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

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


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

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

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

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

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




Though the data are mixed:

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

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




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

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




Each Nature Valley Healthy Heart Bar contains 400 mg sterols.












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













Promise SuperShots contains 400 mg sterols per container.














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














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














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










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

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

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

Why obese people can't fast

Why do obese people claim it is impossible to fast?

Most overweight people are terrified at the prospect of facing any period of time without ready access to food. Persuading them to begin a program of intermittent fasting is a hopeless cause. They just refuse.

Contrary to popular opinion, this is not just glutonny at work. It is the effect of what I call "the cycle of hunger," the 2-hour up and down cycle of rising sugar and insulin, followed by their inevitable fall. The precipitous fall of sugar and insulin triggers mental fogginess, fatigue, and insatiable hunger. (By the way, this is the same phenomenon underlying the silly notion of "grazing.")

According to an LA Times article, fasting may be difficult to impossible for some people:

"Ruth Frechman, a registered dietitian in Burbank and spokeswoman for the American Dietetic Assn., says she frequently sees such extreme strategies backfire. 'You're hungry, fatigued, irritable. Fasting is not very comfortable. People try to cut back one day and the next day they're starving and they overeat.'"
(Not surprising, coming from the American Diatetic Assn. They, along with such agencies as the American Diabetes Association, are vocal proponents of low-fat, high-carbohydrate, "healthy whole grain" diets--you know, the diets that make us fat and diabetic.)

Ms. Frechman is correct: Having someone engage in a period of fasting, no matter how brief, when the diet leading up to the fast is filled with "healthy whole grains" and other carbohydrates will result in painful hunger that eventually overcomes any effort. A period of overeating typically follows the aborted attempt.

Fasting cannot work as long as the 2-hour cycle of hunger continues. The first step: Eliminate the 2-hour cycle of hunger by dramatically reducing or eliminating carbohydrates. Our preferred method is to eliminate wheat, cornstarch, and sugars. (Just be aware of wheat withdrawal, the fatigue that develops in the first 5 days after wheat elimination that affects up to 30% of people.)

Once wheat, cornstarch, and sugars are eliminated, hunger reverts to that of physiologic need--appetite will be smaller and less intense, since it is driven by your body's needs, not by abnormal stimulation from wheat, cornstarch, and sugar. The fear of not having food dissolves, the 2-hour cycle of mental fogginess, fatigue, and hunger will be gone.

Intermittent fasting is a wonderful strategy for reducing weight; gaining control over lipids, lipoproteins, and coronary plaque; regaining appreciation for food; reducing appetite. But it's not even worth trying unless you've already eliminated the unnatural appetite triggers that will booby-trap any fasting effort.

Test your own thyroid

134 people responded to the latest Heart Scan Blog poll:


When I ask my doctor to test my thyroid, he/she:

Accommodates me without question 45 (33%)

Questions why, but orders the tests 49 (36%)

Refuses because you seem "healthy" 20 (14%)

Refuses without explanation 4 (2%)

Ridicules your request 16 (11%)



That's better than I anticipated: 69% of physicians complied with this small request. After all, you're not asking for major surgery. You're just asking for a very basic test, as basic as a blood count or electrolytes. 36% of respondents said that their doctor asked why, but still complied; this is simply practicing good medicine--If there is a problem, your doctor would like to know about it.

However, the remainder--31%--were refused in one way or another. Incredibly, 11% were ridiculed.

Although this was not asked in the poll, I believe that it is a safe assumption that you asked with good reason: you're abnormally fatigued, you have been gaining weight for no apparent reason or can't lose weight despite substantial effort, or you feel cold at inappropriate times.

Let's say you're tired. Ever since last summer, you've suffered a gradual decline in energy.

So you ask your doctor to assess your thyroid. He refuses. "You're just fine! There's nothing wrong with you."

You disagree. In fact, you are quite convinced that there is something physically wrong. What do you do?

You could:

--Drink more coffee
--Exercise more in the hopes that it will snap you out of your lethargy
--Sleep more
--Take stimulants of various sorts

Or, you could get your thyroid assessed and settle the issue. But how can you get this done when your doctor won't accommodate you, even though you have perfectly fine health insurance and are simply interested in feeling better and preserving your health?

You could test your thyroid yourself. This is why we're making self-testing kits available. Test kits are available here.

This is yet another facet of the powerful revolution that is emerging: Self-directed health.

Trains, planes, and heart scans

A Heart Scan Blog reader posted the following question:

It is not clear to me why getting a cardiac scan is the necessary first step, if in fact the next step would be to bring down small LDL particles which is revealed on a NMR lipoprofile or VAP test. Why isn't the NMR or VAP test the first thing?

Good question. Think of it this way:

Lipoproteins, as measured via VAP (Vertical Auto Profile) or NMR (Nuclear Magnetic Resonance), provide a snapshot of risk from a metabolic viewpoint at that moment. Lipoproteins shift with the tides of age, menopause, weight changes, even what you ate last evening for dinner (especially small LDL). There are also other factors that cause coronary plaque, as well, not revealed through lipoprotein testing, such as vitamin D deficiency, smoking, high blood pressure, phosopholipase A2, lipoprotein(a), inflammatory factors, thyroid dysfunction, omega-3 fatty acid deficiency, etc.

A heart scan, providing a coronary calcium score, provides an indirect measure of coronary plaque that is the sum total of lipoprotein and other plaque-causing factors that have accumulated up to the time of your scan--regardless of the cause.

It means that two females, each 60 years old, with 70% small LDL, HDL 42 mg/dl, triglycerides 150 mg/dl, and mild hypertension, have identical markers for potential coronary risk, but can have widely different heart scan scores. One might have a score of zero, while the other might have a score of 300.

Why would the same panel of causes measured at one moment yield wildly different quantities of plaque? Several reasons:

1) The lifestyles, eating habits, and weight of each woman differed during their earlier years, not currently reflected in this moment's lipid or lipoprotein patterns. Perhpaps one experienced several years of extraordinary stress from a failed marriage, or suffered through two years of depression that caused her to smoke and overeat.

2) There are hidden factors that affect coronary plaque growth that we are presently not able to detect, e.g., vitamin D receptor genotype, cholesteryl-ester transfer protein variants, variation in inflammatory factors. If we can't measure it, we won't know whether it might influence coronary plaque risk.


With all the changes that occur over a person's life, with the uncertainties of yet-to-be-identified causes for coronary plaque, how can you possible know what your risk for heart disease truly is? Yup--a heart scan. Do it and you will know.

D2 and D3 are two different things

Helena posted this instructive comment in response to the Heart Scan Blog post, Weight loss and vitamin D. It illustrates the confusion common among physicians and pharmacists on the differences between D2 and D3.

(Edited slightly for clarity.)

Not many weeks ago a colleague of mine (let’s call him Eric) asked me if I knew the difference between D2 and D3 and I told Eric that D2 comes from irradiated mushrooms and D3 comes from wool. In other words, D3 is the same kind of vitamin as humans get from the sun. Humans just don’t get enough and we can’t produce it on our own, like the sheep can. (D3 is natural for humans, D2 is not.)

After telling Eric this, he asked me how he would know what he is taking and I gave him the medical definitions of them both (D2 = Ergocalciferol; D3 = Cholecaliciferol). Since I was aware that he had gotten his Vitamin D by prescription, I told him “I am 99.9% sure that you are taking D2, but I would be thrilled to find out I am wrong.”

Eric called his pharmacy right away and got the answer I was expecting: ergocalciferol. On confronting the person Eric was talking to, the answer he got back was that Ergocalciferol is the only Vitamin D they are giving out.

A week later, Eric had a new appointment with his doctor and decided to ask him about the D2/D3 issue. The doctor said he knew that there was a difference in them both, but could not say what, not even the basic facts I mentioned above. But the doctor stamped a post-it with what he had sent to the pharmacy just to show Eric. “Vitamin D3; 50,000IU tab” is what the stamp said.

Eric, off course, got confused and was starting to believe that the pharmacy had made a mistake by giving him Ergocalciferol (D2) since the doctor had given him D3, or at least that is what was stamped on the little note he had.

Today, after getting a refill of his Vitamin D he also got and kept all his paperwork that came along with it. Still believing that stamp the doctor had given Eric earlier, he asked me to double and triple check that my definition of D2 and D3 was correct. I did, just for my own sanity, and I was still right.

One of the sheets Eric brought me today was the “Patient Education Monograph” sheet stating the drugs and how to use it and so on. The thing that jumped out the most to me was this:

Generic Name: Vitamin D – Oral
Common Brand name(s): Drisdol, Maximum D3
Identification: PA140 Green Oval Capsule

This is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: Ergocalciferol

My researching mind went into high concentration mood and I started to dig. And this is what I found:

The brand name Drisdol is Ergocalciferol (D2), not D3. The Brand name Maximum D3 seems to be hard to find out there in cyber space as a brand name. But the ones I found that were called Maximum D3 seems to be the real stuff, however none of them required a prescription.

When trying to find out through the identification number on the pills (PA140) I now know for sure that Eric is taking Vitamin D2 and not the preferred Vitamin D3. The brand name, Drisdol, had the identification W on one side and D92 on the other, but it is still Ergocalciferol.

The only conclusion I can draw from all this is that the medical industry does not know or care about the difference in D2 and D3 – it is all same to them. And as long as the pharmacies only give out D2 it does not matter what the doctor prescribe anyway.

I know that people are most likely to be prescribed a D2 pill than to be told to buy over-the-counter D3. But it was almost heart breaking to see the letter D and number 3 right next to the drug Drisdol, as we know is a D2 vitamin. It just didn’t make sense to me that they can be labeled as the same type of medication, when we know it is not!



Incredible.

Why prescribe plant form D2 when you can get perfectly reliable, safe, effective D3--the human form, at the health food store for about $6?

Once again, it's the peculiar false bias of physicians and pharmacists: If it's prescription, it must be good; if it comes from a health food store, it must be bogus.

Humans need human vitamin D. Plain and simple.

Weight loss: Different causes, different solutions

Heart Scan Blog reader, Kris, related this enlightening story of weight loss (slightly edited for clarity).

Kris learned that excess weight is gained through multiple causes. The solutions are therefore multiple, not just one change in diet or two.


I started studying about my thyroid issue much earlier and did lose some weight. But ever since I started following Dr. Davis’s blog, it has given me confidence that I was on the right track. I did have my thyroid and iodine figured out from other sources, but Dr. Davis helped me to understand the issues with not only the thyroid but vitamin D3, fructose, fish oil, niacin, wheat etc. I have lost 43lb in last 14 months.

It seems to me that there are certain percentages of weight connected with different issues. For example, after I gave up alcohol and sugar, I lost about 14lbs from total weight of 243lbs, weight came down to about 229lb. Then it stopped at 229lb, even though I was in the gym almost 5 to 6 days a week with full workouts.

After I changed my thyroid medication to natural thyroid hormones (took synthetic T4 for over 10 years), the weight dropped down further 13lbs or so in matter of few days, shape of the face changed from moon shape/double chin to ordinary long face. Then it kind of stopped at around 213-216 lbs.

After giving up wheat, reducing carbs, increasing protein intake (whey protein, chicken etc. no soya, no fructose) the weight came down another 14lbs. Now it is around 200-202lbs and I am over 6.2 tall with heavy set of bones.

I feel better than I have ever in my life. More stamina, more clarity/no fog, more confidence and 99% of the time relaxed and being able to see the situation from multiple angles.

I use to be able to drink a liter or more jack denial without a problem in one evening but now can’t stand half a can of beer (I miss JD). Drinking alcohol makes me sick. I sleep well and if I wake up in the middle of the night, I have no problem going back to sleep. No more out of breath stair climbing at all.

One other thing: I used to be the most attractive meal to the mosquitoes, but not anymore. This year I haven’t been bitten once. I take my dog to the park everyday and I do not use any mosquito repellent, what a relief. I don’t know if it is because of thyroid, iodine, wheat or something else. Skin texture has changed dramatically. I do not use full soap or shampoo, 20% borax, 10 percent of my soap or shampoo for scent and rest water, mixed in a 500ml bottle. No more dandruff, dry skin, pimples for me.

Dr. Davis I am thankful to people like you who have the ability to see beyond what you have been taught and have the guts to say the way it is. Most of us work to make living on daily basis but some make their living while spreading their knowledge to save lives. Dr Davis you are one of those few people. Please keep it going.

Calling all losers!

I'd like to invite anyone who has followed the Track Your Plaque Break the Weight Barrier program to consider posting their stories and photos on the Heart Scan Blog.

Because our focus is prevention and reversal of coronary heart disease, we have not made an effort to catalog the weight loss experience that people have while on the program. For many, weight loss has been substantial. (Several people this week alone have reported weight loss of 9 to 46 lbs in the past 6 months.)

It would be helpful to hear and see these results.

For those of you who don't mind having a story and photo on this Blog, please come back in future to post your results. You will find this post by entering "weight loss" into the site-specific search bar at the top of the page.

Weight loss and vitamin D

At the start of her program, Penny's 25-hydroxy vitamin D blood level showed the usual deficiency at 22 ng/ml.

She supplemented with 8000 units of vitamin D. Another 25-hydroxy vitamin D blood level several months later showed a level of 67.8 ng/ml, right on target.

But Penny also began our diet, including the elimination of wheat, cornstarch, and sugars, and, over 6 months, lost 34 lbs.

Now a much trimmer 146 lbs (still more to go!), another vitamin D blood level: 111 ng/ml.

Penny's weight loss means that the vitamin D is distributed in a smaller total volume, particularly a lower volume of fat.

This is a common phenomenon with substantial weight loss: lose weight and the need for vitamin D is reduced. The reduction in dose is roughly proportion to the weight lost. Vitamin D should therefore be reassessed with any substantial change in weight of, say, 10 lbs or more, either up or down, because of the influence of fat on vitamin D blood levels.

Some references on this effect:

Although the bulk of the effect is most likely due to sequestration by fatty tissue, perhaps less sun exposure in obese people also contributes:

Vitamin D: Treatment for metabolic syndrome?

Vitamin D: Treatment for metabolic syndrome?

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

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

But here's a curious observation:

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

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

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

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

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



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

    Meaningless anecdote: I've noticed an increased tendency to bruise easily since I've been taking higher doses of vitamin D, and had been wondering whether it was the cause. I definitely have metabolic syndrome.

    An irrational fear of skin cancer prevents most people from getting their vitamin D from sunshine. The doses that the medical establishment recommends are so small as to be almost worthless.

    Is cod liver oil the best way to get vitamin D or just vitamin D3 capsules?
    Is there are connection with hypothyroidism and low vitamin D levels?

  • Dr. Davis

    12/23/2007 1:57:00 PM |

    Either source for vitamin D works.

    I do believe that correction of vitamin D has, in occasional instances, modestly increased thyroid function.

  • MarilynMann

    12/23/2007 3:45:00 PM |

    Cod liver oil has a lot of vitamin A, which in excess can lead to low bone density.  It is better just to take the vitamin D by itself.

    I agree -- over 20yrs ago it was suggested that increased thyroid doses are required in the winter time for hypothyroid pts on replacement (see below). IT sure seems to suggest that Vitamin D deficiency exacerbates hypothyroidism (and I'd go as far to say it even CAUSES it)?  I've observed this as well. (it's corrected with D3)

    In the second study, a corollary phenomenon occurred -- thyroid replacement in hypothyroid pts caused 25(OH)D to INCREASE (in the autumn when you'd normally expect it to decrease).  

    Isn't it fascinating how thyroid hormone and D3 hormone are interrelated.
    ---When D3 hormone (sunlight) is lacking, thyroid function suffers
    ---When thyroid hormone is lacking, a high D3 dose fails to increase 25(OH)D much....
    ---When thyroid hormone is NOT lacking, high dose D3 causes a large increase in 25(OH)D (in normal euthryoid controls)

    it all sounds very familiar to me...  Smile

    Is it necessary to adjust the replacement dose of thyroid hormone to the season in patients with hypothyroidism?Hamada N, Ohno M, Morii H, Jaeduk N, Yamakawa J, Inaba M, Ikeda S, Wada M.
    Hypothalamo-pituitary-thyroid activity varies with the temperature of the environment; we therefore measured variables involved with thyroid function in summer and winter in normal controls and in patients with primary hypothyroidism. All seven patients had impalpable thyroid glands and had received a set replacement dose of thyroxine for over a year. In the patients, serum T3 and FT4 levels were slightly but significantly lower in winter, and TSH levels and delta TSH at 30 minutes in the TRH tests were significantly higher. In the controls, there were no significant differences between summer and winter in these values. These findings suggest that the dose required for replacement of thyroid hormone in patients with hypothyroidism may be higher in winter than in summer.

    Effect of vitamin D3 loading and thyroid hormone replacement therapy on the decreased serum 25-hydroxyvitamin D level in patients with hypothyroidism.Bársony J, Lakatos P, Földes J, Fehér T.
    Twelve hypothyroid subjects, 13 healthy and 12 healthy women with a slight deficiency of vitamin D were studied to distinguish seasonal changes from the thyroxine-dependent ones. Serum 25-hydroxyvitamin D levels of hypothyroid patients were lower than those of healthy individuals when the sera were obtained in the autumn. In hypothyroid patients a single oral dose of 100,000 IU vitamin D3 resulted in a smaller increase in 25-hydroxyvitamin D concentration than in controls having subclinical exogenous vitamin D deficiency. Substitution therapy with thyroid hormone, started in our study always in autumn, increased the 25-hydroxyvitamin D concentration in hypothyroid patients, which was opposite to the autumn-to-spring variation of this hormone observed in healthy controls. The increase of 25-hydroxyvitamin D, dehydroepiandrosterone and its sulphate values following substitution therapy in the hypothyroid patients may indicate that thyroid hormone(s) is (are) involved in the regulation of steroid hormone synthesis.

    This is very hopeful...Vitamin D3 stalls thyroid cancer, one case report:

    Endocr J. 2005 Oct;52(5):613-6. Links
    Vitamin D3 treatment for locally advanced thyroid cancer: a case report.Morishita M, Ohtsuru A, Kumagai A, Namba H, Sato N, Hayashi T, Yamashita S.
    Department of Molecular Medicine, Atomic Bomb Disease Institute, Nagasaki University Graduate School of Biomedical Sciences, Japan.

    There are many intricacies in the surgical treatment of locally advanced thyroid cancer, including the medical management of the remaining functional organ and any cosmetic impairments, which are sometimes very difficult to manage and eventually carry a relatively high morbidity and mortality. Here, we report on a case of a 65-year-old female with an extremely locally-advanced thyroid cancer involving both lobes of the thyroid, blood vessels, trachea and esophagus. Despite the severity of her condition, oral administration of vitamin D3 (alphacalcido) has stalled both the tumor growth and further increases of serum thyroglobulin (Tg) level, and has led to a good preservation of quality of life for the last two years. Several reports have previously demonstrated the efficacy of vitamin D3 to inhibit the proliferation of thyroid cancer cell lines in vitro, but clinical evidence has been limited so far. Therefore, this case report provides important evidence for the effectiveness of vitamin D3 therapy against advanced thyroid cancers.

    Another good story... 3mon old child with depressed thyroid function, CHF and profound Vitamin D deficiency in Oslo, Norway -- corrected with a Vit D analogue:

    Congestive heart failure caused by vitamin D deficiency?Brunvand L, Hågå P, Tangsrud SE, Haug E.
    Department of Paediatrics, Ullevål Hospital, Oslo, Norway.

    We describe a child, 3.5 months old, with severe vitamin D deficiency, profound hypocalcaemia, hyperphosphataemia, dilated left ventricle, severely reduced myocardial contractility and congestive heart failure. She also had depressed thyroid function with subnormal thyroxine and non-detectable serum thyrotropin (TSH) levels. The child promptly responded to calcium infusions, conventional anticongestive therapy and calcitriol. She is now 3 years old and received no medication. Myocardial function is normal but she has motor delay. We believe that her transitory congestive heart failure was caused by severe vitamin D deficiency with profound hypocalcaemia.

    Thanks, Marilyn. You're absolutely right.

    In all honesty, I virtually never use cod liver oil, but for some reason some people gravitate towards it, perhaps since they took it as children.

    I went to a local vitamin supplier yesterday to get some Vitamin D after reading your blog, which is most interesting I might add.  At this store they had Vitamin D2 and D3 but no D1.  Is there such a thing (D1) and which is the one I should be taking to benefit as suggested in the blog?

  • Dr. Davis

    12/24/2007 4:59:00 PM |

    Hi, Jerome--

    Vitamin D3 is the only form I recommend. In my view, vitamin D2 is a worthless scam, whether it's in milk, a multivitamin, or a prescription product. I've never heard of vit D1.

    I liked the *idea* of cod liver oil, as it would replace both fish oil and vitamin D tablets - a total of 8 pills in my 26-pill regimen.

    I bought what was supposed to be one of the best tasting ones and... it made me retch.  It also sort of tingles in your mouth.  And because it's oily, you can't rinse it out of your mouth.  It's just icky.

    I gave some to the cats, figuring it would be a healthy snack for them... and all four of them refused it.

    If someone can get it down, I think it's great stuff.  For me, I'll stick to the extra 8 pills...

  • Sue

    Thanks for all the helpful comments.  I've got cod liver oil in the fridge so I think I will use it up and then get D3 capsules.
    I take the cod liver oil with lemon juice.  I put the cod-liver oil in a little shot glass and squeeze some fresh lemon into the shot glass aswell and drink it in one swoop.  I then wash it down with some water with fresh lemon squeezed into it.  Gets rid of some of the icky fishy taste. The lemon also helps with digesting the fat.

    I wouldn't necessarily be afraid of the A, as we can be deficient in the A as well.  Perhaps alternating between A-containing and A-less forms of D supplements would work.  That way you get a vacation from the A periodically.

    As for surviving the fish taste...try following it up with a bite of something else that's strong tasting and contains fat, like cured olives or a tuna salad sandwich.

    Hi Dr. Davis,

    Have you seen literature making a connection to the plaque linked to Alzheimer's disease with the plaque responsible for heart disease?  I was asked this question by a distant cousin yesterday that wondered if the supplements recommended for TYP ,like vitamin D and K2, could help prevent those at risk for Alzheimer's (his grandmother, and mother both came down with Alzheimer's)

  • Dr. Davis

    No, sorry, they are two completely unrelated phenomena, despite the use of the word "plaque" to describe both.

    Fish oil benefits
    Medical Research News
    Published: Sunday, 30-Dec-2007  

    It's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease.
    Many Alzheimer's researchers have long touted fish oil, by pill or diet, as an accessible and inexpensive "weapon" that may delay or prevent this debilitating disease. Now, UCLA scientists have confirmed that fish oil is indeed a deterrent against Alzheimer's, and they have identified the reasons why.

    Reporting in the current issue of the Journal of Neuroscience, now online, Greg Cole, professor of medicine and neurology at the David Geffen School of Medicine at UCLA and associate director of UCLA's Alzheimer Disease Research Center, and his colleagues report that the omega-3 fatty acid docosahexaenoic acid (DHA) found in fish oil increases the production of LR11, a protein that is found at reduced levels in Alzheimer's patients and which is known to destroy the protein that forms the "plaques" associated with the disease.

    The plaques are deposits of a protein called beta amyloid that is thought to be toxic to neurons in the brain, leading to Alzheimer's. Since having high levels of LR11 prevents the toxic plaques from being made, low levels in patients are believed to be a factor in causing the disease.

    Alzheimer's is a debilitating neurodegenerative disease that causes memory loss, dementia, personality change and ultimately death. The national Alzheimer's Association estimates that 5.1 million Americans are currently afflicted with the disease and predicts that the number may increase to between 11 million and 16 million people by the year 2050.

    The researchers examined the effects of fish oil, or its component DHA, in multiple biological systems and administered the oil or fatty acid by diet and by adding it directly to neurons grown in the laboratory.

    "We found that even low doses of DHA increased the levels of LR11 in rat neurons, while dietary DHA increased LR11 in brains of rats or older mice that had been genetically altered to develop Alzheimer's disease," said Cole, who is also associate director of the Geriatric Research Center at the Veterans Affairs Medical Center.

    To show that the benefits of DHA were not limited to nonhuman animal cells, the researchers also confirmed a direct impact of DHA on human neuronal cells in culture as well. Thus, high levels of DHA leading to abundant LR11 seem to protect against Alzheimer's, Cole said, while low LR11 levels lead to formation of the amyloid plaques.

    Fish oil and its key ingredient, omega-3 fatty acids (found in fatty fish like salmon), have been a mainstay of alternative health practitioners for years and have been endorsed by the American Heart Association to reduce the risk of cardiovascular disease.

    Fatty acids like DHA are considered "essential" fatty acids because the body cannot make them from other sources and must obtain them through diet. Years of research have shown that DHA is the most abundant essential fatty acid in the brain, Cole said, and that it is critical to fetal and infant brain development. Studies have also linked low levels of DHA in the brain to cognitive impairment and have shown that lower levels may increase oxidative stress in the brains of Alzheimer's patients.

    Based on the positive results, the National Institutes of Health is currently conducting a large-scale clinical trial with DHA in patients with established Alzheimer's disease. For those patients, Cole said, it may be too late in the disease's progression for DHA to have much effect. But he is hopeful that the NIH will conduct a large-scale prevention clinical trial using fish oil at the earliest stages of the disease - particularly because it is unlikely that a pharmaceutical company will do so, since fish oil in pill form is readily available and inexpensive.

    Still to be determined, he said, "is what the optimal dose should be. It could be that a smaller amount might be helpful, especially in a place like the south of France, where people are already on a Mediterranean diet."

    Here in the United States, though, where fish consumption is not very high, the dose may need to be higher.

    "There's a deficiency of DHA to begin with," Cole said, "and this may contribute to the low LR11 seen in many Alzheimer's patients."

  • Dr. Davis

    I do not advocate use of powder preparations of vit D. The absorption is simply too erratic. oil-based gelcaps are best.

    I wonder what you think of this report? http://www.eurekalert.org/pub_releases/2008-01/bu-vdi010208.php I'm guessing that this is probably Hollick's idea of infiltration - get them to at least accept profitable D2 more before winning them over with D2.

    Also, last year I was prescribed 400IU of D2 which raised my 10nmol/L to 21nmol/L; in realising this is inadequate what would you recommend is a good plan for me?

  • Dr. Davis

    1/4/2008 1:35:00 PM |

    I don't know what to make of Holick's study. He is a source of reliable observations. However, his experience is dramatically different from my experience and that of many others. I have seen D2 have no effect whatsoever repeatedly. I had one woman who had been taking 50,000 units D2 per day have a blood level of D3 of 4 ng/ml.

    Most of my patients take somwhere in the 4000-6000 units per day of vit D3 to generate a blood level of 50-60 ng/ml.

    I saw the study about the vitamin D2 being just as good as D3 also.  Here is the link I read: http://www.nutraingredients.com/news/ng.asp?n=82331-vitamin-d-cholecalciferol-ergocalciferolI thought the article was interesting, until I read the part of the company that made the softgels.  I'd question  what where the Q/C of the content? Did an independent lab test the softgels?

  • Dr. Davis

    1/5/2008 1:52:00 AM |

    Excellent point.

    To me, there is absolutely no reason to take vit D2, given the uncertainty. It is not cheaper, more effective, nor more available. It may, however, be more profitable for a drug company. D3 is the human form; D2 is the plant form.

    Is there any reason at all to take D2? I don't think there is.

    Thanks for the information on Alzheimer's (AD) known now as 'Type 3 Diabetes.' It's conjectured that profound Insulin Resistance in the brain occurs prior to amyloid development in AD patients.  The brain can only use two types of fuel -- ketones (ie like during starvation) and glucose.  There appears to be a problem with excessive glucose.  Some neurobiologist experts believe a mildly ketotic diet may be beneficial for preventing this type of insulin resistance.

    Many benefits in recent studies have shown that fish oil significantly decreases IR associated with Type 2 Diabetes, NAFLD (a precursor to diabetes and believed to be a new indicator for Metabolic Syndrome, non-alcoholic fatty liver dz) and even cancers -- including prostate (shown by Vieth) and glioblastoma -- a rare malignant brain cancer -- thought to be incurable but now being 'cured' with fish oil (and tamoxifen, etc cocktail).

    Hi Dr. Davis,

    I know that you recommend oil-based / gel caps for Vitamin D as opposed to tablets. Does the same hold true for daily multi-vitamins? Is a capsule and a gelcap the same thing?

  • Renee

    Wow another sickness that not enough Vitamin D is contributed to.  I just read an article at Here Comes The Sun talking about ways you can intake more Vitamin D.  Check it out.

  • Dr. Davis

    1/9/2008 3:33:00 AM |

    Paul--
    Vit D gelcaps contain oil. Gelcaps are capsules. However, not all capsules are gelcaps; some contain powder.

    Oil-based vitamins like A, D, and E are best taken as an oil. The D, for instance, in your multivitamin probably doesn't work at all, or absorption is erratic.

    Gelcaps are no more expensive, so why bother with tablet or powder forms?

    Just wondered what your opinion on this anti-D report is? http://www.prweb.com/releases/2008/1/prweb639651.htm

    For what it's worth, I think this guy is going too far. His Marshall Protocol might be entertainable for those with certain autoimmune diseases, but saying D is bad for everyone based on his *personal* model seems nuts. Furthermore, his basic assumption is that everyone with low D 'is' ill, rather than has the potential to. And yet we know treating D in associated illness restores health.

    Would this guy withhold blood because a bullet causes bleeding? No wonder he's not an MD.

    I've witnessed such extraordinary effects of vitamin D replacement that, for me, there is no turning back. Thus far, the effects of vitamin D replacement have paralleled the effects of sun exposure (except for the tan, of course).

    For every new idea, there will always be those who protest. Some have validity, some are plain kooks.

    Dear Dr. Davis,

    Thank you for your support of Vitamin D. I recently was tested and found to have a level of 37. I do have a question or two, though. I was on the mega-dose (50000IU twice a week for four weeks).

    I am now on 2000IU per day (just started this past Sunday). I have all of the Metabolic Syndrome symptoms except the high glucose (my last fasting was 81).

    How long do you think I should continue on this does before I have my level checked again? And how long before I would start to see results?

    My doctor seems very concerned about my CRP (3.1), and I'm really hoping that this vit d. regime helps.
    Thank you.

  • Dr. Davis

    1/24/2008 12:50:00 PM |

    Unfortunately, the "mega-dose" you refer to probably yielding nothing--it was probably vitamin D2 (ergocalciferol). In my experience, this synthetic form fails to be converted to the active form in humans, D3.

    We wait at least 4 weeks before checking a blood level, ideally 8 weeks.

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

    Vitamin D is proving to be a very important and powerful influence on many of the facets of the metabolic syndrome. Because the metabolic syndrome increases the risk of diabetes and cardiovascular disease, an adequate vitamin D level in the body might be important in the prevention of these diseases.

    I was wondering can you have a genetic compenont against making enough vit d by the sun? I bask in the sun for hours (since I love it so much and I am drawn to it like postive charge does to negative charge) yet I am d deficient, I suffer terrible metabolic syndrome, the whole nine yards just short of type 2. my doctor calls me prediabetic.

    I have even improved my diet big time over the last 3 years. lower gi, lower sat fat, more veggies etc. omega 3 fish oil

    I never use sunscreen and I never burn. just a nice light brown tan.I keep this tan by the way almost the whole winter. I started to take a cal vita d mag supplement chewables and I drink whole milk with it to make sure I absorb them being fat soluable and all. I can't expose my belly for more than a few minutes that will burn. ouch!

    being obese I am sure whatever cal vita d I take is going to end up in storage hoarding it an all. what can I do? I now drink more whole milk, eat organic bacon per suggestion from article the obesity epidemic is metabolic syndrome a nutritional deficiency. by stephanic seneff. real nice lady by the way.

    anyway slowly after implementing her suggestions my fasting hypoglycemic especially at night has improved, i don't run to the bathroom like i used to, I am more relaxed too. I have more energy, all this is a slow process not overnight. over many months.

    I don't have to eat at 3 in the morning anymore because of getting super hungry, nervous sweaty etc.

    but I still suffer some of the symptoms just not as severe. is there anything else I can do to speed up the improvments in mets?

    reduced cal diets do not work I get to hungry can't sleep and lose all energy. even a slight reduction which I have done makes me to hungry to sleep at night. or forces me up to eat after a couple of hours of sleep.

    forcing my body to get by on less caloires is not an option. (losing weight is always touted by my doctor to cure mets but mets was caused by my dieting history) I have lost hundreds of pounds over my 35 dieting history.

    I would like to hear any suggestions you may have. my doctor keeps pushing weight loss but that is what got me like this in the first place.
