Unexpected effects of a wheat-free diet 17. September 2009 William Davis (59) 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? 15. September 2009 William Davis (21) 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? 9. September 2009 William Davis (19) 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 outlawedWhile 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. Some more info on sterols in a previous Heart Scan Blog post: Are sterols the new trans fat? .
Why obese people can't fast 9. September 2009 William Davis (21) 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 7. September 2009 William Davis (15) 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 sortsOr, 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 4. September 2009 William Davis (10) 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 3. September 2009 William Davis (15) 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 – OralCommon Brand name(s): Drisdol, Maximum D3Identification: PA140 Green Oval CapsuleThis is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: ErgocalciferolMy 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.For more on the D2 vs. D3 issue, see the Heart Scan Post, The case against vitamin D2.
Weight loss: Different causes, different solutions 1. September 2009 William Davis (8) 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 fa All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in Dr. Cannell comments on vitamin D lab tests 14. July 2008 William Davis (9) As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D. Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here. (I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.) Does it matter what reference lab my doctor uses?Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.Demand for vitamin D tests soars as nutrient's potential benefits touted.Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.My doctor prescribed Drisdol, 50,000 IU per week. What is it?Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.What is the ideal level of 25(OH)D?We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

Am J Clin Nutr. 2008 Jun;87(6):1738-42.I have advanced renal failure and I'm on dialysis, how much vitamin D should I take? The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases. Vieth R. Vitamin D toxicity, policy, and science. J Bone Miner Res. 2007 Dec;22 Suppl 2:V64-8.When I asked my doctor for a 25(OH)D blood test, he just laughed and said it was all idiotic. What can I do? Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.Goodwin JS, Tangum MR.

July 2008 William Davis (9) In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit. Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights. But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly. Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies. Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few. Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled. Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets. I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people. Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on. Dr. Jeffrey Dach on the Track Your Plaque program 10. July 2008 William Davis (5) Dr. Jeffrey Dach posted a great piece on his blog, Bioidentical Hormone Blog , about his perspective on the Track Your Plaque program.

Dr. Cannell comments on vitamin D lab tests 14. July 2008 William Davis (9) As always, Dr. John Cannell of The Vitamin D Council continues to teach us new lessons about vitamin D. Apparently, Dr. Cannell is swamped with the attention that vitamin D is drawing, largely due to his efforts to publicize the enormous deficiency of Americans and his great talent for articulating the science. The most current newsletter, while a bit haphazard, makes some excellent new points that I reprint here. (I did not reprint his conversation about "any form of vitamin D" being acceptable. My experience differs: In nearly 1000 patients who have taken vitamin D supplements, my experience is that most tablet forms are inconsistently absorbed, sometimes not absorbed at all. I therefore advocate only use of gelcaps or liquids. I'm told by members of Track Your Plaque, however, that they are witnessing reliable increases in blood levels of vitamin D by taking the powdered form of Bio Tech Pharmacal's product.) Does it matter what reference lab my doctor uses?Yes, it might make a huge difference. A number of methods exist to measure 25(OH)D in commercial labs. The two most common are mass spectrometry and a chemiluminescence method, LIAISON. The first, mass spectrometry, is highly accurate in the hands of experienced technicians given enough time to do the test properly. However, in the hands of a normally trained technician at a commercial reference lab overwhelmed with 25(OH)D tests, it may give falsely elevated readings, that is, it tells you are OK when in fact you are vitamin D deficient. The second method, chemiluminescence, LIAISON, was recently developed and is the most accurate of the screening, high throughput, methods; LabCorp uses it. Quest Diagnostics reference lab uses mass spec. Again, both Quest and LabCorp are overwhelmed by 25(OH)D requests. The problem is that the faster the technicians do the mass spec test, the more inaccurate it is likely to be. If your 25(OH)D blood test says "Quest Diagnostics" on the top, do not believe you have an adequate level (> 50 ng/ml). You may or may not; the test may be falsely elevated. Let me give you an example. A doctor at my hospital had Quest Diagnostics do a 25(OH)D. It came back as 99 ng/ml of ergocalciferol. He is not taking ergocalciferol (D2), he has never taken ergocalciferol, only cholecalciferol, and he is not taking enough to get a level of 99 ng/ml, 50 ng/ml at the most. His email to Dr. Brett Holmquist at Quest about why Quest identified a substance he was not taking went unanswered other than to say "any friend of Dr. Cannell's is a friend of ours."Long story short: if your lab report says "LabCorp" on the top, it is probably accurate; if it says Quest Diagnostic, it may be falsely elevated. While LabCorp has also been overwhelmed with 25(OH)D requests, the LIAISON method they use is relatively easy to do and does not rely on technician skill as much as the mass spec methods do. I'm not saying this because I'm a consultant for DiaSorin, who makes LIAISON, I'm saying it because it is true. If you don't believe me, get Quest to make me an offer to be their consultant at 10 times what DiaSorin is supposed to be paying me ($10,000 per year) and see how fast I turn Quest down. If Quest fixes their test, I'd love to consult. The ironic thing: I've made both Quest and LabCorp lots of money via this newsletter, the website, and by repeatedly telling the press that people need to know their 25(OH)D level, which has contributed to the skyrocketing sales of 25(OH)D blood tests.Demand for vitamin D tests soars as nutrient's potential benefits touted.Here you can help. Find out which labs in your town use Quest Diagnostics and which use LabCorp. Have a 25(OH)D test at both labs the same day (you will have to pay for them yourself). Then send both results to the Vitamin D Council address below. If Quest Diagnostics does not fix their 25(OH)D test, the Vitamin D Council will fix it for them.My doctor prescribed Drisdol, 50,000 IU per week. What is it?Drisdol is a prescription of 50,000 IU tablets of ergocalciferol or D2. Ergocalciferol is not vitamin D but it is similar. It is made by irradiating ergosterol, which is found in many living things, such as yeast. D2 is not normally found in humans and most studies show it does not raise 25(OH)D levels as well as human vitamin D (cholecalciferol or D3) does. However, Drisdol is a lot better than nothing. The best thing to do, if you are vitamin D deficient, and a human, is to take human vitamin D, cholecalciferol, A.K.A. vitamin D3.What is the ideal level of 25(OH)D?We don't know. However, thanks to Bruce Hollis, Robert Heaney, Neil Binkley, and others, we now know the minimal acceptable level. It is 50 ng/ml. In a recent study, Heaney et al enlarged on Bruce Hollis's seminal work by analyzing five studies in which both the parent compound, cholecalciferol, and 25(OH)D levels were measured. It turn out that the body does not reliably begin storing the parent compound (cholecalciferol) in fat and muscle tissue until 25(OH)D levels get above 50 ng/ml. The average person starts to store cholecalciferol at 40 ng/ml, but at 50 ng/ml, virtually everyone begins to store it for future use. That is, at levels below 50 ng/ml, the body is usually using up the vitamin D as fast as you make it or take it, indicating chronic substrate starvation, not a good thing.

Am J Clin Nutr. 2008 Jun;87(6):1738-42.I have advanced renal failure and I'm on dialysis, how much vitamin D should I take? The same as everyone else. Since I have told you about commercial labs ripping you off, let's add some drug companies. Patients with advanced renal failure need activated vitamin D or one of it's analogs, available by prescription. This is very important as their kidneys cannot make enough 1,25-dihydroxy-vitamin D (calcitriol) to maintain serum calcium. However, the rest of their tissues activate vitamin D just fine and when those tissues get enough, and when the kidneys get more vitamin D, the calcitriol spills out into the blood, lowering their need for prescription calcitriol or one of its analogs. The companies that make the analogs don't like that, it means reduced sales. So these companies do nothing, the scientists behind these companies say nothing, and renal failure patients die prematurely from one of the vitamin D deficiency diseases. Vieth R.

Help me unleash the dogs of war, the plaintiff attorneys. If you read about past nutritional epidemics caused by society, such as beriberi or pellagra, you will realize that education alone will take decades. Physicians successfully fought against the idea that thiamine deficiency caused beriberi for decades. However, things are different now. The agents of change in modern America, as obnoxious as they are, are plaintiff attorneys. Once the first malpractice lawsuits claiming undiagnosed and untreated vitamin D deficiency led to breast cancer, autism, heart disease, etc., get past summary judgment, and they will, and end up in front of a jury, and they will, things will change rapidly. One of the main reason physicians do what they do is fear of lawsuits. In a matter of months, arrogance and ignorance will give way to 25(OH)D tests and vitamin D supplementation.Goodwin JS, Tangum MR.

Privileged information 12. July 2008 William Davis (9) In 1910, taking a person's blood pressure was considered revolutionary, a high-tech practice that was of uncertain benefit. Dr. Harvey Cushing of Johns Hopkins Hospital in Baltimore had observed a blood pressure device while traveling in Europe, developed by Dr. Sciopione Riva-Rocci. Cushing brought this new technology back with him to the U.S. and promptly promoted its use, convinced that this insight into gauging the forcefulness of blood pressure would yield useful clinical insights. But, in 1910, practicing physicians rejected this new technology, preferring to use their well-established and widely practiced technique of pulse palpation (feeling the pulse), skeptical that the new tool added value. Medical practice of the day was rich with descriptions of the strength and character of the pulse: pulsus parvus et tardus (the slow rising pulse of aortic valve stenosis), the dicrotic notch of aortic valve closure transmitted to the pulse, the "water-hammer" pulse of aortic valve insufficiency.Over the next 20 years, however, the medical community finally gave way to the new technique, although only physicians were allowed to use blood pressure devices, as nurses were regarded as incapable of mastering the skills required to perform the procedure properly. Stethoscopes were also gaining in popularity in the early 20th century, but were also the exclusive province of physicians trained in their use. Nurses were not allowed to use stethoscopes until the 1960s. Even then, nurses were not allowed to call them "stethoscopes," but "nurse-o-scopes" or "assistoscopes," and the nurses' version of the device was manufactured to look different to avoid confusion with the "real" doctor's tool.And just half a century ago, if you wanted to look at a medical textbook, you would have to go to the library and ask for special permission. The librarian would lower her glasses and look you up and down to determine whether or not you were some kind of pervert. Only then might you be granted permission to peer into the pictures of organs and naked bodies. Such has been the spirit of medicine for centuries: Medicine and its practices are meant to be secret, the insider knowledge of a privileged few. Fast forward to 2008: The Information Age has overturned the rules of privileged information. Now you have access to the same information as I do, the same information available to practicing physicians. The playing field has been levelled. Curiously, while information access has advanced at an instantaneous digital pace, attitudes in medicine continue to evolve at the traditional analog crawl. Many of my colleagues continue to be dismayed at the new public access to health information, belittle patients for excessive curiosity about their health, lament the erosion of their healthcare-directing authority. And while new concepts race ahead as we race towards a wiki-like collective growth in healthcare knowledge, physicians are still mired by their reluctance to abdicate their once-lofty positions as chief holders of secrets. I believe that this is part of the reason why family doctors and cardiologists have been slow to adopt technologies like heart scans and self-empowering programs like Track Your Plaque: processes that take heart disease prevention away from the hands of physicians and place more control into the hands of the people. Imagine the horror felt by physicians in 1935 of a young upstart nurse boldly trying to use a stethoscope to take a patient's blood pressure. You can imagine the internal horror now being felt as you and I dare to take control over heart disease and deny them the chance to put in four stents, three bypass grafts, then direct our future health habits.But technology has a way of marching on. It will encounter resistance, bumps, and blind-alleys, but it will go on.
