Are endogenous nutritional supplements better? 4. May 2008 William Davis (6) Just a muse. Endogenous substances are those that are already contained within our bodies. They are part of basic human equipment. Exogenous substances are those that come from outside of our bodies. This includes various substances in foods, drugs (most, though not all), and pesticides. I often mull over all of the tools we use in the Track Your Plaque program to achieve control over this thing called coronary plaque. It struck me that just about all the supplements we use that seem to provide outsized benefits are all endogenous substances themselves:--Omega-3 fatty acids from fish oil--Vitamin D--l-arginine--Niacin (vitamin B3)Many of the other substances, though not directly relevant to our plaque-control efforts, but are among the most effective nutritional supplements, also supplement endogenous levels: calcium pyruvate, creatine, acetylcarnitine, DHEA, testosterone, progesterone, growth hormone, pregnenolone, phenylalanine, tyrosine, melatonin, etc. Curiously, most drugs are not meant to directly supplement endogenous levels, but are designed either to enhance or block an enzyme (e.g., acetylcholinesterase inhibitors that block breakdown of acetylcholine; HMG CoA reductase inhibitors to block cholesterol synthesis; angiotensin converting enzyme inhibitors to reduce blood pressure), to exert toxic effects on an organism (antibiotics, antivirals), or to exert an entirely unique effect that does not ordinarily occur in the human body (some anti-cancer drugs, for instance). (This is an admitted, vast over-simplification.)That's not to say that any endogenous substance is desirable or safe when supplemented. Cortisol, thyroid hormone, and estrogens are three examples of endogenous substances that have downsides when administered at slightly more than physiologic concentrations. Nonetheless, it makes me wonder if the world of endogenous substance supplementation has not been fully explored. Are there other endogenous substances that are as potent and wonderful, for instance, as vitamin D but not yet fully appreciated? I'm sure there are.
Vitamin D Newsletter reprinted 1. May 2008 William Davis (2) Reprinted here is the unfailingly informative Vitamin D Newsletter from Dr. John Cannell. Although there's little here specifically about heart disease, there's so much great information about vitamin D that I thought most would still appreciate it. The Vitamin D NewsletterMay, 2008Yesterday's Washington Post article, Too-Good-To-Be-True Nutrient?, sums up the April 9th vitamin D symposium at UCSD in San Diego, which was nothing short of spectacular. Carole Baggerly outdid herself organizing it and explaining how she got involved. Make no mistake; Carole is both serious and energetic. She told about her efforts to introduce resolutions at upcoming meetings of various professional groups. Then she introduced the volunteers from the San Diego Black Nurses Association who made sure the conference went off without a hitch. Then Carole introduced the four speakers. The slides of each speaker are available at Grassroots Health. Before I tell you the highlights of the conference, I'd like to tell you about another conference, this one in Germany, this May 17th and 18th. It is the Third International Symposium on Vitamin D Analogs in Cancer Prevention and Therapy. Readers know how I feel about giving analogs to vitamin D deficient patients instead of vitamin D but speakers include Michael Holick, Reinhold Veith, Bill Grant, Tai Chen, Heidi Cross, David Feldman, and Roger Bouillon, all of whom know the importance of the nutrient. Most of this conference is for scientists, not lay people. However, Michael Holick is the first speaker and if you have not heard his latest talk about vitamin D, it might be worth a trip to Germany.The first San Diego speaker was Dr. William Grant. Since leaving NASA to begin a full-time career as a vitamin D researcher, Bill has published dozens of studies and has another dozen in the works. Using ecological studies (from Greek oikos, house + German -logie, study or studying your own house) of UVB irradiance and cancer, Bill reported that 15 cancers (colon, esophageal, gallbladder, gastric, pancreatic, rectal, small intestinal, bladder, kidney, prostate, breast, endometrial, ovarian, Hodgkin's lymphoma, and non-Hodgkin's lymphoma) are associated with lower UVB light. He concluded that 257,000 cancer deaths in 2007 in the USA were accounted for by inadequate vitamin D levels. Of course the problem with ecological studies is that it easy to be vitamin D deficient in Miami, all you have to do is listen to your doctor's advice and stay out of the sun. Recently, a group from the Arizona Cancer Center found almost 80% of Arizonians had levels below 30 ng/ml. So much for sunny spots.Jacobs ET, et al. Vitamin D insufficiency in southern Arizona. Am J Clin Nutr. 2008 Mar;87(3):608-13.The next speaker was Professor Cedric Garland. I found myself wondering how he did it. I became convinced that vitamin D prevents cancer five years ago. Cedric and his brother Frank and his colleague Ed Gorham knew it 30 years ago! I know what it is like to tell someone that vitamin D prevents cancer and see them think, "Here we go again, another miracle vitamin." I know what it is like to try and explain and watch people die unnecessarily. But I've only had that experience for five years. Cedric has dealt with that frustration for thirty years. Almost thirty years ago, Cedric and Frank Garland published evidence that vitamin D prevents cancer. In fact, it was Cedric's first publication. Thankfully, the paper was recently recognized as being so important that it was republished in 2006 by the International Journal of Epidemiology. You can read the entire paper for free by clicking on the second link below and then clicking on "free final text", courtesy of Oxford Journals.Garland CF, Garland FC. Do sunlight and vitamin D reduce the likelihood of colon cancer? Int J Epidemiol. 1980 Sep;9(3):227-31.Garland CF, Garland FC. Do sunlight and vitamin D reduce the likelihood of colon cancer? Int J Epidemiol. 2006 Apr;35(2):217-20. Cedric began by showing the incidence of type-1 diabetes and multiple sclerosis by latitude. I had no idea that the latitudinal data was so strong for type 1 diabetes in children. This disease is almost nonexistent around the equator. Type-1 diabetes is but one of the three modern childhood epidemics caused by the sunlight-hating dermatologists, the other two, I think, are autism and asthma. Next he showed latitude and 25(OH)D levels, which reminded me to be suspicious of high levels, unless they use accurate methods of detecting 25(OH)D. Some methods used, even in this country, are over detecting vitamin D and telling patients their levels are above 50 ng/ml when they are, in reality, much lower. Cedric's data showed Thailand had mean levels of 70 ng/ml, which I doubt and suspect were due to inaccurate 25(OH)D tests. He then reviewed evidence of the 25(OH)D levels needed to prevent numerous cancers. The safest levels are somewhere above 50 ng/ml. Cedric spent most of his time presenting an entirely new theory of carcinogenesis, one dependent on vitamin D maintaining cellular junctions. I suspect this paper will also be reprinted in 20 years. The only disagreement I have is with his recommendation for cancer patients to start at fairly low doses. For reasons I recently explained, the risk benefit analysis indicates cancer patients should take 5,000 to 10,000 IU per day and they may have no time to lose. Why worry about the phantom of vitamin D toxicity if you may be dying of cancer? Just have your calcium checked along with frequent 25(OH)D levels. Get your levels up to 70-90 ng/ml if you have cancer.Does vitamin D treat cancer?The next speaker was Professor Bruce Hollis. He reviewed basic physiology of vitamin D and emphasized that the entire system is designed to deal with an excess not with an insufficiency of vitamin D. Numerous mechanisms are available in your body to prevent vitamin D toxicity but few are available to deal with insufficiency. Then he briefly mentioned one of the most important discoveries about vitamin D in the last few years, one where Professor Neil Binkley of the University of Wisconsin was senior author. (In the last four years, Professor Binkley has become a prolific vitamin D expert and I hope Carol Baggerly is able to get him to speak at some of the upcoming conferences she hopes to sponsor.) As I have pointed out before, Hollis and Binkley's crucial discovery was that the body doesn't start storing the parent compound, cholecalciferol, until 25(OH)D levels reach about 50 ng/ml. They showed, using basic steroid pharmacology, that 50 ng/ml should be considered the lower limit of adequate 25(OH)D levels.Hollis BW, Wagner CL, Drezner MK, Binkley NC. Circulating vitamin D3 and 25-hydroxyvitamin D in humans: An important tool to define adequate nutritional vitamin D status. J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):631-4. Bruce kept the audience enthralled with a review of all the disease states that indicate 25(OH)D levels need to be much higher than they are now, that is, the multiple biomarkers that suggest the lower limit of 25(OH)D levels should be above 40 ng/ml and closer to 50 ng/ml. Then Professor Hollis spoke of his ongoing study in pregnant women and how he got approval to use 4,000 IU of vitamin D per day back in 2003, quite an accomplishment. He also reviewed another one of his research projects, one that answered an age old question, why is breast milk a poor source of vitamin D? How were prehistoric infants supposed to get their vitamin D, by lying out in the sun where saber tooth tigers would eat them? No, they were hidden in caves and had to have another source or the human race would have died out long ago because rickets destroys a woman's and infant's chance to live through childbirth due to rachitic deformations of the mother's pelvis. Carol Wagner and Bruce Hollis, together with their colleagues, answered that age old question, human breast milk is a poor vitamin D source because virtually all modern mothers are vitamin D deficient. That is, when pregnant women keep their levels where we think prehistoric human levels were, about 50 ng/ml, breast milk becomes a rich source of vitamin D. First Carol and Bruce gave 2,000 IU per day, then 4,000 IU per day and finally 6400 IU of D3 per day to lactating women. Only at 6400 of D3/day did the women maintain both their own 25(OH)D levels and the levels of their breast feeding babies above 50 ng/ml. On 6400 IU/day, the vitamin D activity of the breast milk went from about 80 to 800 IU/L. Quite a discovery, and another reason for all of us to keep our levels above 50 ng/ml.Wagner CL, Hulsey TC, Fanning D, Ebeling M, Hollis BW. High-dose vitamin D3 supplementation in a cohort of breastfeeding mothers and their infants: a 6-month follow-up pilot study. Breastfeed Med. 2006 Summer;1(2):59-70.Professor Robert Heaney went last, discussing 74 slides. So much of what we know about vitamin D today is due to Robert's unceasing dedication to vitamin D, the most recent example being his and Joanne Lappe's randomized controlled trial showing that increasing baseline levels from 29 to 38 ng/ml reduced the risk of getting cancer by around 70%. He again pointed out that the body does not begin to consistently store much vitamin D until your levels get to around 50 ng/ml. He also went through multiple biomarkers of vitamin D. That is, what level or intakes do you have to have to reduce the incidence of multiple diseases? He covered calcium absorption, osteoporosis, risk of falling, muscle function, death and disability of the aged, TB, influenza, cardiovascular disease, hypertension, diabetes, cancer, multiple sclerosis, and gum disease. How can one vitamin be involved in so many diseases? Simple said Dr. Heaney, "vitamin D is the key that unlocks the DNA library." He then reviewed toxicity and concluded there is no evidence that it occurs at levels below 200 ng/ml or with intakes (total) below 30,000 IU per day. Of course, we have no reason to think anyone needs 30,000 IU per day or levels of 200 ng/ml, which would be irresponsible. But someone with a serious cancer should consider getting their level up to 70-90 ng/ml and that may take 10,000 IU per day or even more in some people. As a rule of thumb, 1,000 IU will raise 25(OH)D levels by about 10 ng/ml. Then Professor Heaney addressed a public health question. How much would we have to give all Americans to get 98% of people above 32 ng/ml without causing toxicity in anybody? The answer: 2,000 IU per day. Of course 32 ng/ml is not adequate but it would be a great first step. Furthermore, of the people left out, a high percentage would be African Americans. In fact, Dr. Talwar recently reported that 40% of African American women fail to achieve a level of 30 ng/ml even after taking 2,000 IU/day for a year.Talwar SA, Aloia JF, Pollack S, Yeh JK. Dose response to vitamin D supplementation among postmenopausal African American women. Am J Clin Nutr. 2007 Dec;86(6):1657-62.He also discussed his recent study giving healthy adults 100,000 IU as a single dose. If you start with a baseline level of 28 ng/ml and take 100,000 IU as a single dose, mean levels will remain above 32 ng/ml for two months. If you rely on such stoss doses, but you start with a lower level, or want your levels above 50 ng/ml, how often do you need to take 100,000 IU? We don't know the answer to the last question but we know that Grey et al gave 50,000 IU per week for four weeks then 50,000 per month for a year to 21 patients with hyperparathyroidism. Blood levels rose from a mean of 11 ng/ml at baseline to 30 ng/ml at one year and levels did not continue to rise after six months. Remember, that means half the patients had levels lower than 30 ng/ml at the end of the year. Also remember that the metabolic clearance (how quickly you use it up) might be higher in certain disease states.Grey A, et al. Vitamin D repletion in patients with primary hyperparathyroidism and coexistent vitamin D insufficiency. J Clin Endocrinol Metab. 2005 Apr;90(4):2122-6. That last point, metabolic clearance, is only one of a number of reasons that patients vary in their response to vitamin D. Remember, a surprising number of patients will tell their physician they are taking vitamin D when they are not, some will be taking preparations that have less in it than the label says, some will not absorb it, and some people weigh more than others. As Dr. Heaney points out, even if you know patients took 100,000 IU, great variably exists in individual response. At the end of two months some will have shown a minimal response and other much more. This is a field where little is known. Do different disease states use up vitamin D quickly? The answer is probably yes. Furthermore, variability also exists in how one metabolizes and catabolizes (breaks down) vitamin D. Also, what is the interactive effect of drugs that use the same liver enzymes for catabolism? We just don't know and that is why vitamin D blood testing is crucial. Remember, the only test to have is a 25-hydroxy-vitamin D. Do not let anyone get a 1,25-dihydroxy-vitamin D; it will not tell you if you are vitamin D deficient and is usually only indicated in evaluating high blood calcium.As far as 25(OH)D levels go, many of you have written complaining about the high cost of a 25(OH)D levels at some labs. I've got some good news. For the next month, Life Extension Foundation is having a sale on their 25(OH)D blood tests, only $32.25, including the fee for drawing the blood. (No, we don't get funding from Life Extension, I wish we did.) Life Extension uses LabCorp, which, in turn, uses an accurate method to determine 25(OH)D levels, the DiaSorin Laiason method. The only problem is that DiaSorin, LabCorp, and Life Extension all say that 30 ng/ml is acceptable. It is not. Take enough vitamin D or get enough UVB radiation to get your levels above 50 ng/ml. To order the test, call Life Extension at 800 208-3444. Unfortunately, this offer is not available in New York, New Jersey or Rhode Island.Also, Dr. James Dowd has written a fine book about vitamin D, The Vitamin D Cure. Get this, he is board certified in internal medicine, adult rheumatology, and pediatric rheumatology, an associate professor at Michigan State University, and runs his own Arthritis Institute and the Michigan Arthritis Research Center. He gives a formula for how much vitamin D you need but stresses the importance of testing to know for sure. He uses the formula of 2000 IU for every 100 pounds of body weight, which is as accurate an estimation as one can make without knowing baseline levels. Of course it depends on so many things, as Dr. Dowd points out, such as percentage body fat, latitude, skin type, sun exposure Toggle navigation Home Blog Home Archive Join Now Log in Another interview with Livin' La Vida Low Carb's Jimmy Moore 7. January 2009 William Davis (4) I recently provided another interview for Livin' La Vida Low Carb's Jimmy Moore. You may remember Jimmy as the irrepressible host of the Livin' La Vida Low Carb Show who lost around 200 lbs, dropping from 410 to 230 lbs on a low-carbohydrate diet. In this hour-long interview, we discussed some of the dietary strategies that we use in the Track Your Plaque program. Jimmy's website is definitely worth exploring. It's loaded with great interviews, including with Good Calories, Bad Calories author, Gary Taubes. "Millions of needless deaths" 6. January 2009 William Davis (4) "Millions of needless deaths" is the title of an editorial by Life Extension Magazine's Bill Faloon.". . . If vitamin D’s only benefit was to reduce coronary heart attack rates by 142%, the net savings (after deducting the cost of the vitamin D) if every American supplemented properly would be around $84 billion each year. That’s enough to put a major dent in the health care cost crisis that is forecast to bankrupt Medicare and many private insurance plans."Although I don't agree with all the over-the-top commentary that issues from Mr. Faloon or Life Extension (although I sit on their Medical Advisory Board), I agree with virtually all of the issues he raises with vitamin D.Despite the enormously compelling observations of vitamin D potential effects in populations, the medical community's reluctance comes from the lack of treatment data. In other words, what we lack are long-term data on vitamin D supplementation vs. placebo on rate of heart attack, vitamin D vs. placebo on risk of colon cancer, etc.The data that exists connecting vitamin D levels with cardiovascular risk originate from three population observations:1) The NHANES data in 16,000 participants showed 20% increased risk of cardiovascular events in those with vitamin D levels <20>20 ng/ml after factoring in all standard risk factors.Another NHANES analysis showed the high prevalence of vitamin D deficiency in those with cardiovascular disease.2) A German study of 2500 participants that showed showed the lowest quartile of vitamin D levels (<13.3>28.4 ng/ml.3) The Health Professionals' Follow-Up Study of 18,000 males showed a 2.4-fold increase in cardiovascular events in those with vitamin D levels <15>30 ng/ml.While we lack treatment data (vitamin D vs. placebo) in a large population, we do have data that Suzie Rockway, Mary Kwasny (both from Rush University, Chicago) and I generated on the effect of vitamin D as a part of a broader treatment program on coronary calcium scores:Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.Davis W, Rockway S, Kwasny M. Amer J Ther 2008 (Dec 15). The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides =60 lipoprotein high-density dL; mg>/=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.I also summed up the data as of early 2008 in a Life Extension article:Vitamin D's Crucial Role in Cardiovascular ProtectionI do agree with Mr. Faloon: It's time to take the vitamin D issue very seriously. Personally, I think it is foolhardy to not correct vitamin D deficiency, even in the absence of long-term treatment data.Should we subject people living in tropical climates with vitamin D blood levels of 90 ng/ml to long-term observation? Though that has not yet been done, it has been done--in effect--through observations on the prevalence of diabetes, heart disease, and various cancers by latitude: the farther away from the equator, the greater the prevalence of these diseases.That's more than good enough for me. Thiazide diuretics: Treatment of choice for high blood pressure? 5. January 2009 William Davis (14) Thiazide diuretics are a popular first-line treatment for hypertension among the primary care set.This practice became especially well-established with the 2002 publication of the ALLHAT Study (Major Outcomes in High-Risk Hypertensive Patients Randomized to Angiotensin-Converting Enzyme Inhibitor or Calcium Channel Blocker vs Diuretic:The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT)). ALLHAT showed that an inexpensive diuretic like chlorthalidone (a weak diuretic in the thiazide class, similar to hydrochlorothiazide) as first-line treatment for hypertension achieved equivalent reductions in cardiovascular events (cardiovasular death and heart attack) as non-thiazide antihypertensives, lisinopril (an ACE inhibitor) and amlodipine (a calcium channel blocker, better known as Norvasc). After 7 years of treatment, there was 14% death or heart attack among all three groups--no difference. This was interpreted to mean that inexpensive thiazide diuretics like chlorthalidone offer as much benefit as other blood pressure medications at reduced cost. On the surface, that's great. Anything that detracts from the ubiquitous pharmaceutical industry propaganda of bigger, better, more expensive drugs to replace old, inexpensive, generic drugs is fine by me. But you knew there'd be more to this issue! If we accept that thiazides are equivalent to other single-drug treatments for high blood pressure, what do we do with the following issues:--Thiazides deplete body potassium-This effect can be profound. In fact, built into the ALLHAT mortality rate is an expected death rate from potassium depletion. When potassium in the body and blood go low, the heart becomes electrically unstable and dangerous rhythms develop. --Thiazides deplete magnesium--Similar in implication to the potassium loss, magnesium loss also creates electrical instability in the heart, not to mention exaggeration of insulin resistance, rise in triglycerides, reduction in HDL.--Thiazides reduce HDL cholesterol--Thiazides increase triglycerides--Thiazides increase small LDL particles--You know, the number one cause for heart disease in the U.S. --Thiazides increase uric acid--Uric acid is increasingly looking like a coronary risk factor: The higher the uric acid blood level, the greater the risk for heart attack. Thiazides have long been known to increase uric acid, occasionally sufficient to trigger attacks of gout (uric acid crystals that precipitate in joints, like rock candy). (Fully detailed Special Report on uric acid coming this week on the Track Your Plaque website.)What about the advice we commonly give people to hydrate themselves generously? Yet we give them diuretics? Which is it: More hydration or less hydration? You can't have both. Do thiazides exert an apparent cardiovascular risk reduction in a society due to its flagrant sodium obsession? Thus, there are a number of inconsistencies in the thinking surrounding thiazides. In my experience, I have seen more harm done than good using these agents. While I cannot fully reconcile the reported benefit seen in ALLHAT with what I see in real life, all too often I see people having to take another drug to make up for a side-effect of a thiazide diuretic (e.g., high-dose prescription potassium to replace lost potassium, allopurinol to reduce uric acid, etc.). I have seen many people get hospitalized, even suffer near-fatal or fatal events from extremely low potassium or magnesium levels. My personal view: ALLHAT or no, avoid thiazide diuretics like the plague. Sure, it might save money on a population basis, but I suspect that the ALLHAT data are deeply misleading. What's better than a thiazide, calcium blocker, or ACE inhibitor? How about vitamin D restoration, thyroid normalization, wheat elimination? "High-dose" Vitamin D 30. December 2008 William Davis (43) I stumbled on one of the growing number of local media stories on the power of vitamin D. In one story, a purported "expert" was talking about the benefits of "high-dose" vitamin D, meaning up to 1000, even 2000 units per day. I regard this as high-dose---for an infant. Judging by my experiences, now numbering well over 1000 patients over three years time, I'd regard this dose range not as "high dose," nor moderate dose, perhaps not even low dose. I'd regard it as barely adequate. Though needs vary widely, the majority of men require 6000 units per day, women 5000 units per day. Only then do most men and women achieve what I'd define as desirable: 60-70 ng/ml 25-hydroxy vitamin D blood level. I base this target level by extrapolating from several simple observations: --In epidemiologic studies, a blood level of 52 ng/ml seems to be an eerily consistent value: >52 ng/ml and cancer of the colon, breast, and prostate become far less common; <52 ng/ml and cancers are far more likely. I don't know about you, but I'd like to have a little larger margin of safety than just achieving 52.1 ng/ml. --Young people (not older people >40 years old, who have lost most of the capacity to activate vitamin D in the skin) who obtain several days to weeks of tropical sun typically have 25-hydroxy vitamin D blood levels of 80-100 ng/ml without adverse effect. More recently, having achieved this target blood level in many people, I can tell you confidently that achieving this blood level of vitamin D achieves:--Virtual elimination of "winter blues" and seasonal affective disorder in the great majority--Dramatic increases in HDL cholesterol (though full effect can require a year to develop)--Reduction in triglycerides--Modest reduction in blood pressure--Dramatic reduction in c-reactive protein (far greater than achieved with Crestor, JUPITER trial or no)--Increased bone density (improved osteoporosis/osteopenia)--Halting or reversal of aortic valve disease(I don't see enough cancer in my cardiology practice to gauge whether or not there has been an impact on cancer incidence.)My colleagues who have bothered to participate in the vitamin D conversation have issued warnings about not going "overboard" with vitamin D, generally meaning a level of >30 ng/ml. I know of no rational basis for these cautions. If hypercalcemia (increased blood calcium) is the concern, then calcium levels can be monitored. I can reassure them that calcium levels virtually never go up in people (without rare diseases like sarcoid or hyperparathyroidism). Then why any hesitation in recreating blood levels that are enjoyed by tropical inhabitants exposed to plentiful sun that achieve these extraordinary health effects? For the present, I have applied the target level of 60-70 ng/ml without apparent ill-effect. In fact, I have witnessed nothing but hugely positive effects. Vitamin D Home Test 29. December 2008 William Davis (13) The ever-resourceful Dr. John Cannell of the Vitamin D Council has announced the availability of an at-home, self-ordered vitamin D test kit for $65. The Vitamin D Council newsletter is reprinted below. (However, please note that, as wonderful as the advice Dr. Cannell provides, I don't agree on several small points, such as the lack of need for vitamin D if you use a tanning bed or obtain "sufficient" sun; I have seen many people with dark tans, virtually all over 40 years old, who are still severely deficient. I attribute this to the lost capacity for vitamin D activation as we age.) I have not used this service. Should anyone choose to try it, please let us know how it goes. The Vitamin D NewsletterDecember 28, 2008 The Vitamin D Council is happy to announce that we have partnered with ZRT Laboratory to provide an inexpensive, $65.00, in-home, accurate, vitamin D [25(OH)D] test. The usual cost for this test is between $100.00 and $200.00. If you read this newsletter, you know about our interest in accurate vitamin D testing. In the next few weeks, you may read about the Vitamin D Council's quest for accurate vitamin D blood tests in the national media. Before we partnered with ZRT, we verified, repeatedly, that ZRT provides accurate and reliable vitamin D tests and that their method corresponds very well to the gold standard of vitamin D blood tests, the DiaSorin RIA. Our ZRT service is not just inexpensive, it means no more worrying about your doctor ordering the right test or interpreting it correctly. You buy the test kit on the internet or by phone, a few days later the kit comes in the mail, you or a nurse friend do a finger stick, collect a few drops of blood, and send the blotter paper back to ZRT in the postage paid envelope provided with the kit. A week later you get results back in the mail and know accurate 25-hydroxy-vitamin D levels of you and your family. For every test you order, ZRT will donate $10.00 to the Vitamin D Council. Please read the new page hyperlinked below on our website as it both explains the procedure and how to order the test. http://www.vitamindcouncil.org/health/deficiency/am-i-vitamin-d-deficient.shtml Executive summary: keep your family's 25-hydroxy-vitamin D blood test above 50 ng/ml, year around. Most adults need at least 5,000 IU per day, especially this time of year. Most children need at least 1,000 IU per day per every 25 pounds of body weight.

December 2008 William Davis (9) People pay about $90 per year to become Members on the Track Your Plaque website. This provide access to our in-depth Special Reports, guides, webinars, and our proprietary software data tracking tools. Members can also participate in online discussions, such as those in the Track Your Plaque Forum and chats. Why is there a charge for membership in the program and where does the money go? Money raised from membership fees goes towards: 1) The costs of doing business, e.g., server fees, software purchases, legal fees. Hosting webinars, for instance, costs us about $99 per month for the GoToWebinar software service. 2) Software development--Our most recent round of software data tracking tools, for instance, cost us nearly $30,000. That may not be a lot from big business standards, but it is onerous enough that obtaining membership dues really helps. 3) Graphics development--A website without graphics would be awfully dull, regardless of the quality of the textual content. Some of the newest tools on the Track Your Plaque website require photography and graphics work, which can add up very quickly. Where membership fees do NOT go: 1) In our pockets--In fact, except for the various contractors who are paid for their services (e.g., software developers), NOBODY on the Track Your Plaque staff are paid: not me, nor any of the behind-the-scenes staff. Some of the staff overlap with my office staff, but they are paid purely out of the office revenues, not out of Track Your Plaque membership dues. 2) Towards overhead costs beyond those listed above--For example, membership fees do not pay for office lease, utilities, phones, etc. We rely on membership fees because we have chosen to remain as free of commercial bias as possible. We host no advertising, we have no behind-the-scenes corporate or institutional agendas, we show no favoritism to any business or commercial operation. We believe this permits editorial freedom that few other health websites can enjoy. (In fact, I know of no other that is so free of commercial bias, outside of small blogs or narrow-interest websites.) If you want to see what damage commercial bias can create, just go to a health website like WebMD. I challenge you to find information that is not flagrantly biased by commercial influence, namely that of the drug industry. (According to the WebMD SEC filings, in fact, the great majority--approximately 80%--of their $331 million revenues (2007) were derived directly or indirectly from the drug industry.) This commercial bias reaches into all of WebMD's related businesses, including MedicineNet.com, RxList.com, Medscape.com, and several others. Preventing heart disease is not a money maker, sad to say. It is, from the perspective of conventional heart care, a big money loser. Undergo a heart catheterization, hospitalization, stent or bypass for anywhere from $14,000 to well over $100,000---or pay $90 for in-depth health information that dramatically reduces the potential need for the hospital and its procedures, minimizes need for prescription medication (statins alone, of course, are a $27 billion annual revenue phenomenon), and achieves all this by maximizing nutrition, self-purchased nutritional supplements, and inexpensive heart scans. Nobody is going to make a bundle off of this approach. So that is why we charge a membership fee. I often get a laugh from some of the comments of people on this blog or even in my office who believe that we are rolling in money from the website from membership dues. The opposite is true: We don't pay ourselves. Virtually every penny is reinvested back into the website to better serve the Members. Getting your dose of fish oil right 23. December 2008 William Davis (11) Confusion often stems from the simplest of calculations: dose of fish oil. Actually, you and I don't take fish oil for fish oil. We take fish oil for its content of omega-3 fatty acids, the dominant ones being EPA and DHA. The contents of fish oil outside of its EPA + DHA content likely exert little or no benefit (beyond that of other dietary oils).To determine what you are currently taking, simply examine the back of your fish oil bottle and look for the EPA + DHA composition. This should be clearly and prominently labeled. If not, don't buy that brand again. Add up the EPA + DHA content per capsule, then multiply by the number of capsules you take per day. That yields your daily EPA + DHA intake. The only other substantial source of omega-3 fatty acids is fish. Other food sources, such as non-fish meats, eggs, etc., contribute little or none. Processed foods that bear health claims of "contains heart healthy omega-3" often contain linolenic acid or flaxseed oil, which contributes very little to total EPA + DHA, or contain relatively trivial quantities of DHA. What are you doing eating processed foods, anyway? What should the total daily dose of EPA + DHA dose be? That depends on what your goals are. If your goal is to modestly reduce the risk of dying from heart attack, then just eating fish a couple of times per month will begin to exert an effect, or just taking a dose of 300 mg EPA + DHA per day from a low-potency capsule will do it. However, that's an awfully unambitious goal. Our starting omega-3 dose in the Track Your Plaque program has, over the years, increased and now stands at 1800 mg EPA + DHA per day. However, the dose for 1) full reduction of triglycerides and/or triglyceride-containing abnormal lipoproteins, 2) reduction of Lp(a), and 3) the ideal dose for coronary and carotid plaque control are substantially higher. But once you know your desired daily target of total EPA + DHA, you can easily determine the quantity of capsules to take by doing the above arithemetic, totaling the EPA + DHA per capsule. For example, if you have been instructed to take 6000 mg per day EPA + DHA, and your capsule contains 750 mg EPA + DHA, then you will need to take 8 capsules per day (6000/750). Flat tummy . . . or, Why your dietitian is fat 19. December 2008 William Davis (19) When I go to the hospital, I am continually amazed at some of the hospital staff: 5 ft 4 inch nurses weighing over 200 lbs, etc. But what I find particularly bothersome are some (not all) hospital dietitans--presumably experts at the day-to-day of healthy eating--who waddle through the halls, easily 40, 50, or more pounds overweight. It is, to say the least, credibility-challenging for an obese dietitian to be providing nutritional advice to men or women recovering after bypass or stent while clearly not in command of nutritional health herself. What's behind this perverse situation? How can a person charged to dispense "healthy" nutritional information clearly display such clear-cut evidence of poor nutrition? How would you view a success coach dressed in rags? Or a reading coach who can barely read a sentence? Easy: She follows her own advice. Hospital dietitians are essentially forced to adhere to nutritional guidelines of "official" organizations, such as the American Heart Association and the USDA. There is some reason behind this. Imagine a rogue dietitian decides to advocate some crazy diet that yields dangerous effects, e.g., high-potassium diets in people with kidney disease. There is a role for oversite on the information any hospital staff member dispenses. The problem, of course, doesn't lie with the dietitian, but with the organizations drafting the guidelines. For years, the mantra of hospital diets was "low-fat." More recently, this dated message has begun--only begun--to falter, but now replaced with the "healthy, whole grain" mantra. And that is the advice the hapless dietitian follows herself, unwittingly indulging in foods that make us fat. Sadly, the "healthy, whole grain" message also contributes to heart disease via drop in HDL, increased triglycerides, a huge surge in small LDL, rise in blood sugar, increased resistance to insulin, tummy fat, and diabetes. Yes, the diet provided to survivors of heart attack increases risk. The "healthy, whole grain" message also enjoys apparent "validation" through the enormous proliferation of commercial products cleverly disguised as healthy: Cheerios, Raisin Bran, whole grain bread, whole wheat pasta, etc. The "healthy, whole grain" message, while a health disaster, is undoubtedly a commercial success. I'll bet that our fat dietitian friend enjoys a breakfast of healthy, whole grains in skim milk, followed by a lunch of low-fat chicken breast on two slices of whole grain bread, and ends her day with a healthy meal of whole wheat pasta. She then ascribes her continually climbing weight and size 16 figure to slow metabolism, lack of exercise, or the once-a-week piece of chocolate. Wheat has no role in the Track Your Plaque program for coronary plaque control and reversal. In fact, my personal view is that wheat has no role in the human diet whatsoever. More on this concept can be found at: What's worse than sugar? The Wheat-Deficiency Syndrome Nutritional approaches: Large vs. Small LDLAre you wheat-free? Statin drug revolt 16. December 2008 William Davis (28) I sense a growing revolt against the intrusion of statin drugs into our lives. No doubt, the statin drug industry is, at least from an economic perspective, a huge success: $27 billion annual revenues at last accounting. The latest big plug for more and more statins was the JUPITER trial that showed reduced cardiovascular events on Crestor in people with "normal" LDL cholesterol levels and increased c-reactive protein. It seems that not one day passes that doesn't include some news story about the "benefits" of statin drugs: reduction in heart attack, stroke, colon cancer, osteoporosis, heart failure, etc. Ironically, the overwhelming economic success of the statin drug industry also seems to be encouraging a grassroots revolt. More and more people are coming to the office, more people commenting on the web over how they want to avoid statin drugs, stop a drug they are already taking, or at least reduce the dose of an ongoing drug.My day-to-day experience with coronary plaque control and reversal is that, while statin drugs are helpful tools, they are not necessary tools for full benefit of a prevention program. "Need" for statin drugs can differ by the patterns measured, though not the usual patterns suggested by the drug industry. For instance, using C-reactive protein, a la JUPITER, as justification for statin prescription is, in my view, totally absurd and makes no sense whatsoever, since inflammatory responses can be effective reduced with plenty of other strategies besides statin drugs. Conventional LDL, likewise, is a fictitious number that often bear little or no resemblance to the true and genuine measured value (apoprotein B or LDL particle number). So here are a number of strategies that can help reduce or eliminate the "need" for a statin drug:--Elimination of wheat and cornstarch--This is no namby-pamby dietary strategy, as low-fat diets were. This is a powerful, enormously effective strategy, particularly if LDL is in the small category. Small LDL drops like a stone when these foods are eliminated. This means no breads, pasta, breakfast cereals, pretzels, crackers, chips, tacos, wraps, etc. --Non-wheat fibers--Especially raw nuts, ground flaxseed, and oat bran. --Vitamin D restoration--Fish oil --Weight loss--NiacinThere are additional strategies that focus on specific subsets of LDL cholesterol (e.g., Lp(a) masquerading as LDL). But the above list can reduce LDL cholesterol substantially, reducing the apparent "need" for a statin drug.You will notice that there are few money makers in the above list, compared to the billions of dollars reaped by the statin drug industry. There is therefore little incentive to allow a pretty sales rep to go to your doctor and pitch the use of over-the-counter vitamin D or make changes in diet. Statin drugs in my view need to be shoved back into their more limited role as drugs to be used on occasion when necessary (e.g., heterozygous familial hypercholesterolemia with LDL cholesterol values of 250 mg/dl in a person with measurable coronary plaque). These should never have achieved the "celebrity" status they enjoy, complete with gushing endorsements by TV personalities, daily news stories, and back-to-back TV commercials. Join the revolt! Lovaza Rip-off 14. December 2008 William Davis (107) Lovaza is GlaxoSmithKline's prescription fish oil, an ethyl ester modification to allow higher concentration of omega-3 fatty acids, EPA + DHA, per capsule. Each capsule contains 840 mg EPA + DHA. It is FDA-approved for treatment of high triglycerides (>500 mg/dl). In their marketing, they claim "Unlike LOVAZA, dietary supplements are not FDA approved to treat any disease." They also highlight the "patented five-step" purification process that eliminates any concerns over mercury or pesticide residues. What does Lovaza cost? In Milwaukee, it costs about $70 per capsule per month (PCPM). Most people are taking four capsules per day: $280 per month, or $3360 per year to obtain 3360 mg of EPA + DHA per day. (Funny coincidence with the numbers.) Did you catch that? $3360 per year, just for one person to take Lovaza. What if I instead went to Costco and bought their high-potency fish oil. This is also an ethyl ester form. It costs $14.99 for 180 capsules, or $2.50 PCPM; each capsule contains 684 mg EPA + DHA. I would therefore have to take five capsules per day to obtain the same 3360 mg EPA + DHA per day. This would cost me 5 x $2.50 = $12.50 per month, or $150 per year. $3360 per year vs. $150 per year to obtain the same dose of omega-3 fatty acids, or a 22.4-fold difference. Lovaza is FDA-approved for treatment of high triglycerides. But I am seeing more and more people take it for other reasons at this four-capsule-per-day dose. Regardless, this "drug" is adding $3360 per year costs to our healthcare. A school teacher, for instance, recently commented to me that she didn't care about the costs, since her insurance (in Milwaukee county, teachers have unbelievably generous healthcare coverage) covers Lovaza. I've heard this from others: insurance covers it, so they don't care how much it costs. Guess who eventually has to pay the $3360 per year per person costs? Yup, you and me. We all bitch and moan about the costs of healthcare and health insurance, but many of us are more than willing to shift the costs to our friends and neighbors to save a few bucks. You think Lipitor makes a bundle of money for Pfizer at about $120 per month? Lovaza is making a bundle of money for GlaxoSmithKline, and all because people are cheap and willing to selfishly shift costs to other people. Keep in mind that $3360 per year is just for fish oil. It's not for surgery, it's not for hospital care, it's just for stinking fish oil. << Older posts Newer posts >> Newer posts12...495051525354555657...123124Older posts
Another interview with Livin' La Vida Low Carb's Jimmy Moore 7. January 2009 William Davis (4) I recently provided another interview for Livin' La Vida Low Carb's Jimmy Moore. You may remember Jimmy as the irrepressible host of the Livin' La Vida Low Carb Show who lost around 200 lbs, dropping from 410 to 230 lbs on a low-carbohydrate diet. In this hour-long interview, we discussed some of the dietary strategies that we use in the Track Your Plaque program. Jimmy's website is definitely worth exploring. It's loaded with great interviews, including with Good Calories, Bad Calories author, Gary Taubes.
"Millions of needless deaths" 6. January 2009 William Davis (4) "Millions of needless deaths" is the title of an editorial by Life Extension Magazine's Bill Faloon.". . . If vitamin D’s only benefit was to reduce coronary heart attack rates by 142%, the net savings (after deducting the cost of the vitamin D) if every American supplemented properly would be around $84 billion each year. That’s enough to put a major dent in the health care cost crisis that is forecast to bankrupt Medicare and many private insurance plans."Although I don't agree with all the over-the-top commentary that issues from Mr. Faloon or Life Extension (although I sit on their Medical Advisory Board), I agree with virtually all of the issues he raises with vitamin D.Despite the enormously compelling observations of vitamin D potential effects in populations, the medical community's reluctance comes from the lack of treatment data. In other words, what we lack are long-term data on vitamin D supplementation vs. placebo on rate of heart attack, vitamin D vs. placebo on risk of colon cancer, etc.The data that exists connecting vitamin D levels with cardiovascular risk originate from three population observations:1) The NHANES data in 16,000 participants showed 20% increased risk of cardiovascular events in those with vitamin D levels <20>20 ng/ml after factoring in all standard risk factors.Another NHANES analysis showed the high prevalence of vitamin D deficiency in those with cardiovascular disease.2) A German study of 2500 participants that showed showed the lowest quartile of vitamin D levels (<13.3>28.4 ng/ml.3) The Health Professionals' Follow-Up Study of 18,000 males showed a 2.4-fold increase in cardiovascular events in those with vitamin D levels <15>30 ng/ml.While we lack treatment data (vitamin D vs. placebo) in a large population, we do have data that Suzie Rockway, Mary Kwasny (both from Rush University, Chicago) and I generated on the effect of vitamin D as a part of a broader treatment program on coronary calcium scores:Effect of a Combined Therapeutic Approach of Intensive Lipid Management, Omega-3 Fatty Acid Supplementation, and Increased Serum 25 (OH) Vitamin D on Coronary Calcium Scores in Asymptomatic Adults.Davis W, Rockway S, Kwasny M. Amer J Ther 2008 (Dec 15). The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of >/= 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides =60 lipoprotein high-density dL; mg>/=60 mg/dL; and vitamin D3 supplementation to achieve serum levels of >/=50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program.I also summed up the data as of early 2008 in a Life Extension article:Vitamin D's Crucial Role in Cardiovascular ProtectionI do agree with Mr. Faloon: It's time to take the vitamin D issue very seriously. Personally, I think it is foolhardy to not correct vitamin D deficiency, even in the absence of long-term treatment data.Should we subject people living in tropical climates with vitamin D blood levels of 90 ng/ml to long-term observation? Though that has not yet been done, it has been done--in effect--through observations on the prevalence of diabetes, heart disease, and various cancers by latitude: the farther away from the equator, the greater the prevalence of these diseases.That's more than good enough for me.
Thiazide diuretics: Treatment of choice for high blood pressure? 5. January 2009 William Davis (14) Thiazide diuretics are a popular first-line treatment for hypertension among the primary care set.This practice became especially well-established with the 2002 publication of the ALLHAT Study (Major Outcomes in High-Risk Hypertensive Patients Randomized to Angiotensin-Converting Enzyme Inhibitor or Calcium Channel Blocker vs Diuretic:The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT)). ALLHAT showed that an inexpensive diuretic like chlorthalidone (a weak diuretic in the thiazide class, similar to hydrochlorothiazide) as first-line treatment for hypertension achieved equivalent reductions in cardiovascular events (cardiovasular death and heart attack) as non-thiazide antihypertensives, lisinopril (an ACE inhibitor) and amlodipine (a calcium channel blocker, better known as Norvasc). After 7 years of treatment, there was 14% death or heart attack among all three groups--no difference. This was interpreted to mean that inexpensive thiazide diuretics like chlorthalidone offer as much benefit as other blood pressure medications at reduced cost. On the surface, that's great. Anything that detracts from the ubiquitous pharmaceutical industry propaganda of bigger, better, more expensive drugs to replace old, inexpensive, generic drugs is fine by me. But you knew there'd be more to this issue! If we accept that thiazides are equivalent to other single-drug treatments for high blood pressure, what do we do with the following issues:--Thiazides deplete body potassium-This effect can be profound. In fact, built into the ALLHAT mortality rate is an expected death rate from potassium depletion. When potassium in the body and blood go low, the heart becomes electrically unstable and dangerous rhythms develop. --Thiazides deplete magnesium--Similar in implication to the potassium loss, magnesium loss also creates electrical instability in the heart, not to mention exaggeration of insulin resistance, rise in triglycerides, reduction in HDL.--Thiazides reduce HDL cholesterol--Thiazides increase triglycerides--Thiazides increase small LDL particles--You know, the number one cause for heart disease in the U.S. --Thiazides increase uric acid--Uric acid is increasingly looking like a coronary risk factor: The higher the uric acid blood level, the greater the risk for heart attack. Thiazides have long been known to increase uric acid, occasionally sufficient to trigger attacks of gout (uric acid crystals that precipitate in joints, like rock candy). (Fully detailed Special Report on uric acid coming this week on the Track Your Plaque website.)What about the advice we commonly give people to hydrate themselves generously? Yet we give them diuretics? Which is it: More hydration or less hydration? You can't have both. Do thiazides exert an apparent cardiovascular risk reduction in a society due to its flagrant sodium obsession? Thus, there are a number of inconsistencies in the thinking surrounding thiazides. In my experience, I have seen more harm done than good using these agents. While I cannot fully reconcile the reported benefit seen in ALLHAT with what I see in real life, all too often I see people having to take another drug to make up for a side-effect of a thiazide diuretic (e.g., high-dose prescription potassium to replace lost potassium, allopurinol to reduce uric acid, etc.). I have seen many people get hospitalized, even suffer near-fatal or fatal events from extremely low potassium or magnesium levels. My personal view: ALLHAT or no, avoid thiazide diuretics like the plague. Sure, it might save money on a population basis, but I suspect that the ALLHAT data are deeply misleading. What's better than a thiazide, calcium blocker, or ACE inhibitor? How about vitamin D restoration, thyroid normalization, wheat elimination?
"High-dose" Vitamin D 30. December 2008 William Davis (43) I stumbled on one of the growing number of local media stories on the power of vitamin D. In one story, a purported "expert" was talking about the benefits of "high-dose" vitamin D, meaning up to 1000, even 2000 units per day. I regard this as high-dose---for an infant. Judging by my experiences, now numbering well over 1000 patients over three years time, I'd regard this dose range not as "high dose," nor moderate dose, perhaps not even low dose. I'd regard it as barely adequate. Though needs vary widely, the majority of men require 6000 units per day, women 5000 units per day. Only then do most men and women achieve what I'd define as desirable: 60-70 ng/ml 25-hydroxy vitamin D blood level. I base this target level by extrapolating from several simple observations: --In epidemiologic studies, a blood level of 52 ng/ml seems to be an eerily consistent value: >52 ng/ml and cancer of the colon, breast, and prostate become far less common; <52 ng/ml and cancers are far more likely. I don't know about you, but I'd like to have a little larger margin of safety than just achieving 52.1 ng/ml. --Young people (not older people >40 years old, who have lost most of the capacity to activate vitamin D in the skin) who obtain several days to weeks of tropical sun typically have 25-hydroxy vitamin D blood levels of 80-100 ng/ml without adverse effect. More recently, having achieved this target blood level in many people, I can tell you confidently that achieving this blood level of vitamin D achieves:--Virtual elimination of "winter blues" and seasonal affective disorder in the great majority--Dramatic increases in HDL cholesterol (though full effect can require a year to develop)--Reduction in triglycerides--Modest reduction in blood pressure--Dramatic reduction in c-reactive protein (far greater than achieved with Crestor, JUPITER trial or no)--Increased bone density (improved osteoporosis/osteopenia)--Halting or reversal of aortic valve disease(I don't see enough cancer in my cardiology practice to gauge whether or not there has been an impact on cancer incidence.)My colleagues who have bothered to participate in the vitamin D conversation have issued warnings about not going "overboard" with vitamin D, generally meaning a level of >30 ng/ml. I know of no rational basis for these cautions. If hypercalcemia (increased blood calcium) is the concern, then calcium levels can be monitored. I can reassure them that calcium levels virtually never go up in people (without rare diseases like sarcoid or hyperparathyroidism). Then why any hesitation in recreating blood levels that are enjoyed by tropical inhabitants exposed to plentiful sun that achieve these extraordinary health effects? For the present, I have applied the target level of 60-70 ng/ml without apparent ill-effect. In fact, I have witnessed nothing but hugely positive effects.
Vitamin D Home Test 29. December 2008 William Davis (13) The ever-resourceful Dr. John Cannell of the Vitamin D Council has announced the availability of an at-home, self-ordered vitamin D test kit for $65. The Vitamin D Council newsletter is reprinted below. (However, please note that, as wonderful as the advice Dr. Cannell provides, I don't agree on several small points, such as the lack of need for vitamin D if you use a tanning bed or obtain "sufficient" sun; I have seen many people with dark tans, virtually all over 40 years old, who are still severely deficient. I attribute this to the lost capacity for vitamin D activation as we age.) I have not used this service. Should anyone choose to try it, please let us know how it goes. The Vitamin D NewsletterDecember 28, 2008 The Vitamin D Council is happy to announce that we have partnered with ZRT Laboratory to provide an inexpensive, $65.00, in-home, accurate, vitamin D [25(OH)D] test. The usual cost for this test is between $100.00 and $200.00. If you read this newsletter, you know about our interest in accurate vitamin D testing. In the next few weeks, you may read about the Vitamin D Council's quest for accurate vitamin D blood tests in the national media. Before we partnered with ZRT, we verified, repeatedly, that ZRT provides accurate and reliable vitamin D tests and that their method corresponds very well to the gold standard of vitamin D blood tests, the DiaSorin RIA. Our ZRT service is not just inexpensive, it means no more worrying about your doctor ordering the right test or interpreting it correctly. You buy the test kit on the internet or by phone, a few days later the kit comes in the mail, you or a nurse friend do a finger stick, collect a few drops of blood, and send the blotter paper back to ZRT in the postage paid envelope provided with the kit. A week later you get results back in the mail and know accurate 25-hydroxy-vitamin D levels of you and your family. For every test you order, ZRT will donate $10.00 to the Vitamin D Council. Please read the new page hyperlinked below on our website as it both explains the procedure and how to order the test. http://www.vitamindcouncil.org/health/deficiency/am-i-vitamin-d-deficient.shtml Executive summary: keep your family's 25-hydroxy-vitamin D blood test above 50 ng/ml, year around. Most adults need at least 5,000 IU per day, especially this time of year. Most children need at least 1,000 IU per day per every 25 pounds of body weight. Bio Tech Pharmacal provides high quality and inexpensive vitamin D. Currently Bio Tech Pharmacal is providing vitamin D for numerous scientific studies. To see their prices and for ordering, click the hyperlink below. http://www.bio-tech-pharm.com/catalog.aspx?cat_id=2 As a gift to our readers for the New Year, Thorne publications have provided a free download to a basic paper about vitamin D.

Where do Track Your Plaque membership revenues go? 26. December 2008 William Davis (9) People pay about $90 per year to become Members on the Track Your Plaque website. This provide access to our in-depth Special Reports, guides, webinars, and our proprietary software data tracking tools. Members can also participate in online discussions, such as those in the Track Your Plaque Forum and chats. Why is there a charge for membership in the program and where does the money go? Money raised from membership fees goes towards: 1) The costs of doing business, e.g., server fees, software purchases, legal fees. Hosting webinars, for instance, costs us about $99 per month for the GoToWebinar software service. 2) Software development--Our most recent round of software data tracking tools, for instance, cost us nearly $30,000. That may not be a lot from big business standards, but it is onerous enough that obtaining membership dues really helps. 3) Graphics development--A website without graphics would be awfully dull, regardless of the quality of the textual content. Some of the newest tools on the Track Your Plaque website require photography and graphics work, which can add up very quickly. Where membership fees do NOT go: 1) In our pockets--In fact, except for the various contractors who are paid for their services (e.g., software developers), NOBODY on the Track Your Plaque staff are paid: not me, nor any of the behind-the-scenes staff. Some of the staff overlap with my office staff, but they are paid purely out of the office revenues, not out of Track Your Plaque membership dues. 2) Towards overhead costs beyond those listed above--For example, membership fees do not pay for office lease, utilities, phones, etc. We rely on membership fees because we have chosen to remain as free of commercial bias as possible. We host no advertising, we have no behind-the-scenes corporate or institutional agendas, we show no favoritism to any business or commercial operation. We believe this permits editorial freedom that few other health websites can enjoy. (In fact, I know of no other that is so free of commercial bias, outside of small blogs or narrow-interest websites.) If you want to see what damage commercial bias can create, just go to a health website like WebMD. I challenge you to find information that is not flagrantly biased by commercial influence, namely that of the drug industry. (According to the WebMD SEC filings, in fact, the great majority--approximately 80%--of their $331 million revenues (2007) were derived directly or indirectly from the drug industry.) This commercial bias reaches into all of WebMD's related businesses, including MedicineNet.com, RxList.com, Medscape.com, and several others. Preventing heart disease is not a money maker, sad to say. It is, from the perspective of conventional heart care, a big money loser. Undergo a heart catheterization, hospitalization, stent or bypass for anywhere from $14,000 to well over $100,000---or pay $90 for in-depth health information that dramatically reduces the potential need for the hospital and its procedures, minimizes need for prescription medication (statins alone, of course, are a $27 billion annual revenue phenomenon), and achieves all this by maximizing nutrition, self-purchased nutritional supplements, and inexpensive heart scans. Nobody is going to make a bundle off of this approach. So that is why we charge a membership fee. I often get a laugh from some of the comments of people on this blog or even in my office who believe that we are rolling in money from the website from membership dues. The opposite is true: We don't pay ourselves. Virtually every penny is reinvested back into the website to better serve the Members.
Getting your dose of fish oil right 23. December 2008 William Davis (11) Confusion often stems from the simplest of calculations: dose of fish oil. Actually, you and I don't take fish oil for fish oil. We take fish oil for its content of omega-3 fatty acids, the dominant ones being EPA and DHA. The contents of fish oil outside of its EPA + DHA content likely exert little or no benefit (beyond that of other dietary oils).To determine what you are currently taking, simply examine the back of your fish oil bottle and look for the EPA + DHA composition. This should be clearly and prominently labeled. If not, don't buy that brand again. Add up the EPA + DHA content per capsule, then multiply by the number of capsules you take per day. That yields your daily EPA + DHA intake. The only other substantial source of omega-3 fatty acids is fish. Other food sources, such as non-fish meats, eggs, etc., contribute little or none. Processed foods that bear health claims of "contains heart healthy omega-3" often contain linolenic acid or flaxseed oil, which contributes very little to total EPA + DHA, or contain relatively trivial quantities of DHA. What are you doing eating processed foods, anyway? What should the total daily dose of EPA + DHA dose be? That depends on what your goals are. If your goal is to modestly reduce the risk of dying from heart attack, then just eating fish a couple of times per month will begin to exert an effect, or just taking a dose of 300 mg EPA + DHA per day from a low-potency capsule will do it. However, that's an awfully unambitious goal. Our starting omega-3 dose in the Track Your Plaque program has, over the years, increased and now stands at 1800 mg EPA + DHA per day. However, the dose for 1) full reduction of triglycerides and/or triglyceride-containing abnormal lipoproteins, 2) reduction of Lp(a), and 3) the ideal dose for coronary and carotid plaque control are substantially higher. But once you know your desired daily target of total EPA + DHA, you can easily determine the quantity of capsules to take by doing the above arithemetic, totaling the EPA + DHA per capsule. For example, if you have been instructed to take 6000 mg per day EPA + DHA, and your capsule contains 750 mg EPA + DHA, then you will need to take 8 capsules per day (6000/750).
Flat tummy . . . or, Why your dietitian is fat 19. December 2008 William Davis (19) When I go to the hospital, I am continually amazed at some of the hospital staff: 5 ft 4 inch nurses weighing over 200 lbs, etc. But what I find particularly bothersome are some (not all) hospital dietitans--presumably experts at the day-to-day of healthy eating--who waddle through the halls, easily 40, 50, or more pounds overweight. It is, to say the least, credibility-challenging for an obese dietitian to be providing nutritional advice to men or women recovering after bypass or stent while clearly not in command of nutritional health herself. What's behind this perverse situation? How can a person charged to dispense "healthy" nutritional information clearly display such clear-cut evidence of poor nutrition? How would you view a success coach dressed in rags? Or a reading coach who can barely read a sentence? Easy: She follows her own advice. Hospital dietitians are essentially forced to adhere to nutritional guidelines of "official" organizations, such as the American Heart Association and the USDA. There is some reason behind this. Imagine a rogue dietitian decides to advocate some crazy diet that yields dangerous effects, e.g., high-potassium diets in people with kidney disease. There is a role for oversite on the information any hospital staff member dispenses. The problem, of course, doesn't lie with the dietitian, but with the organizations drafting the guidelines. For years, the mantra of hospital diets was "low-fat." More recently, this dated message has begun--only begun--to falter, but now replaced with the "healthy, whole grain" mantra. And that is the advice the hapless dietitian follows herself, unwittingly indulging in foods that make us fat. Sadly, the "healthy, whole grain" message also contributes to heart disease via drop in HDL, increased triglycerides, a huge surge in small LDL, rise in blood sugar, increased resistance to insulin, tummy fat, and diabetes. Yes, the diet provided to survivors of heart attack increases risk. The "healthy, whole grain" message also enjoys apparent "validation" through the enormous proliferation of commercial products cleverly disguised as healthy: Cheerios, Raisin Bran, whole grain bread, whole wheat pasta, etc. The "healthy, whole grain" message, while a health disaster, is undoubtedly a commercial success. I'll bet that our fat dietitian friend enjoys a breakfast of healthy, whole grains in skim milk, followed by a lunch of low-fat chicken breast on two slices of whole grain bread, and ends her day with a healthy meal of whole wheat pasta. She then ascribes her continually climbing weight and size 16 figure to slow metabolism, lack of exercise, or the once-a-week piece of chocolate. Wheat has no role in the Track Your Plaque program for coronary plaque control and reversal. In fact, my personal view is that wheat has no role in the human diet whatsoever. More on this concept can be found at: What's worse than sugar? The Wheat-Deficiency Syndrome Nutritional approaches: Large vs. Small LDLAre you wheat-free?
Statin drug revolt 16. December 2008 William Davis (28) I sense a growing revolt against the intrusion of statin drugs into our lives. No doubt, the statin drug industry is, at least from an economic perspective, a huge success: $27 billion annual revenues at last accounting. The latest big plug for more and more statins was the JUPITER trial that showed reduced cardiovascular events on Crestor in people with "normal" LDL cholesterol levels and increased c-reactive protein. It seems that not one day passes that doesn't include some news story about the "benefits" of statin drugs: reduction in heart attack, stroke, colon cancer, osteoporosis, heart failure, etc. Ironically, the overwhelming economic success of the statin drug industry also seems to be encouraging a grassroots revolt. More and more people are coming to the office, more people commenting on the web over how they want to avoid statin drugs, stop a drug they are already taking, or at least reduce the dose of an ongoing drug.My day-to-day experience with coronary plaque control and reversal is that, while statin drugs are helpful tools, they are not necessary tools for full benefit of a prevention program. "Need" for statin drugs can differ by the patterns measured, though not the usual patterns suggested by the drug industry. For instance, using C-reactive protein, a la JUPITER, as justification for statin prescription is, in my view, totally absurd and makes no sense whatsoever, since inflammatory responses can be effective reduced with plenty of other strategies besides statin drugs. Conventional LDL, likewise, is a fictitious number that often bear little or no resemblance to the true and genuine measured value (apoprotein B or LDL particle number). So here are a number of strategies that can help reduce or eliminate the "need" for a statin drug:--Elimination of wheat and cornstarch--This is no namby-pamby dietary strategy, as low-fat diets were. This is a powerful, enormously effective strategy, particularly if LDL is in the small category. Small LDL drops like a stone when these foods are eliminated. This means no breads, pasta, breakfast cereals, pretzels, crackers, chips, tacos, wraps, etc. --Non-wheat fibers--Especially raw nuts, ground flaxseed, and oat bran. --Vitamin D restoration--Fish oil --Weight loss--NiacinThere are additional strategies that focus on specific subsets of LDL cholesterol (e.g., Lp(a) masquerading as LDL). But the above list can reduce LDL cholesterol substantially, reducing the apparent "need" for a statin drug.You will notice that there are few money makers in the above list, compared to the billions of dollars reaped by the statin drug industry. There is therefore little incentive to allow a pretty sales rep to go to your doctor and pitch the use of over-the-counter vitamin D or make changes in diet. Statin drugs in my view need to be shoved back into their more limited role as drugs to be used on occasion when necessary (e.g., heterozygous familial hypercholesterolemia with LDL cholesterol values of 250 mg/dl in a person with measurable coronary plaque). These should never have achieved the "celebrity" status they enjoy, complete with gushing endorsements by TV personalities, daily news stories, and back-to-back TV commercials. Join the revolt!
Lovaza Rip-off 14. December 2008 William Davis (107) Lovaza is GlaxoSmithKline's prescription fish oil, an ethyl ester modification to allow higher concentration of omega-3 fatty acids, EPA + DHA, per capsule. Each capsule contains 840 mg EPA + DHA. It is FDA-approved for treatment of high triglycerides (>500 mg/dl). In their marketing, they claim "Unlike LOVAZA, dietary supplements are not FDA approved to treat any disease." They also highlight the "patented five-step" purification process that eliminates any concerns over mercury or pesticide residues. What does Lovaza cost? In Milwaukee, it costs about $70 per capsule per month (PCPM). Most people are taking four capsules per day: $280 per month, or $3360 per year to obtain 3360 mg of EPA + DHA per day. (Funny coincidence with the numbers.) Did you catch that? $3360 per year, just for one person to take Lovaza. What if I instead went to Costco and bought their high-potency fish oil. This is also an ethyl ester form. It costs $14.99 for 180 capsules, or $2.50 PCPM; each capsule contains 684 mg EPA + DHA. I would therefore have to take five capsules per day to obtain the same 3360 mg EPA + DHA per day. This would cost me 5 x $2.50 = $12.50 per month, or $150 per year. $3360 per year vs. $150 per year to obtain the same dose of omega-3 fatty acids, or a 22.4-fold difference. Lovaza is FDA-approved for treatment of high triglycerides. But I am seeing more and more people take it for other reasons at this four-capsule-per-day dose. Regardless, this "drug" is adding $3360 per year costs to our healthcare. A school teacher, for instance, recently commented to me that she didn't care about the costs, since her insurance (in Milwaukee county, teachers have unbelievably generous healthcare coverage) covers Lovaza. I've heard this from others: insurance covers it, so they don't care how much it costs. Guess who eventually has to pay the $3360 per year per person costs? Yup, you and me. We all bitch and moan about the costs of healthcare and health insurance, but many of us are more than willing to shift the costs to our friends and neighbors to save a few bucks. You think Lipitor makes a bundle of money for Pfizer at about $120 per month? Lovaza is making a bundle of money for GlaxoSmithKline, and all because people are cheap and willing to selfishly shift costs to other people. Keep in mind that $3360 per year is just for fish oil. It's not for surgery, it's not for hospital care, it's just for stinking fish oil.
