Don't forget the pumpkin in the wheat-free pumpkin bread 25. December 2010 William Davis (3) Ooops!Anyone who receives this blog via RSS feed may have received the Wheat-free pumpkin bread recipe in which I failed to list the pumpkin in the list of ingredients. Here's the recipe with all the ingredients.
Wheat-free pumpkin bread 25. December 2010 William Davis (5) Try this recipe for a wheat-free, gluten-free yet healthy "bread." Unlike many gluten-free foods that send blood sugar skyward, this will not. Ingredients:2 cups ground almond meal (Buy it from Trader Joe's--70% cheaper than other grocery stores.)1/2 cup ground flaxseed1/2 cup sour cream (full-fat, of course)15 oz canned pumpkin (Trader Joe's is bisphenol A-free)2 medium to large eggs1/2 cup chopped walnuts or pecans4 tablespoons butter, melted2 teaspoons baking powder2 teaspoons cinnamon1 teaspoon nutmeg or allspiceDash of saltChoice of non-nutritive sweetener (I used 3 teaspoons Trader Joe's stevia extract powder, the one mixed with lactose. Two tablespoons of Truvia, 1/2 teaspoon of the more concentrated stevia extract, or 1/2 cup Splenda are other choices. You can taste the mixed batter to gauge sweetness if in doubt.) Preheat oven to 350 degrees F. Grease baking pan (e.g., 10 x 6 inch). The pan should be big enough so that the mix will not be more than 2 inches deep, else it will require much longer to bake. (If you have only smaller pans, you will need to cook longer while the pan is covered with aluminum foil.) Mix all ingredients thoroughly in large bowl. Pour mix into greased baking pan. Cover with aluminum foil and bake for 30 minutes. Remove foil and bake for additional 30 minutes or until inserted toothpick or knife comes out dry. Serve with cream cheese or as is. (I'd have some pictures, but the kids and I ate it up before I thought to take any photographs.)
Vitamin D: Deficiency vs optimum level 19. December 2010 William Davis (20) Dr. James Dowd of the Vitamin D Cure posted his insightful comments regarding the Institute of Medicine's inane evaluation of vitamin D. Dr. Dowd hits a bullseye with this remark:The IOM is focusing on deficiency when it should be focusing on optimal health values for vitamin D. The scientific community continues to argue about the lower limit of normal when we now have definitive pathologic data showing that an optimal vitamin D level is at or above 30 ng/mL. Moreover, if no credible toxicity has been reported for vitamin D levels below 200 ng/mL, why are we obsessing over whether our vitamin D level should be 20 ng/mL or 30 ng/mL?Yes, indeed. Have no doubts: Vitamin D deficiency is among the greatest public health problems of our age; correction of vitamin D (using the human form of vitamin D, i.e., D3 or cholecalciferol, not the invertebrate or plant form, D2 or ergocalciferol) is among the most powerful health solutions. I have seen everything from relief from winter "blues," to reversal of arthritis, to stopping the progression of aortic valve disease, to partial reversal of dementia by achieving 25-hydroxy vitamin D levels of 50 ng/ml or greater. (I aim for 60-70 ng/ml.) The IOM's definition of vitamin D adequacy rests on what level of 25-hydroxy vitamin D reverses hyperparathyroidism (high PTH levels) and rickets. Surely there is more to health than that. Dr. Dowd and vocal vitamin D advocate, Dr. John Cannell, continue to champion the vitamin D cause that, like many health issues, conradicts the "wisdom" of official organizations like the IOM.
Large LDL counts, too 15. December 2010 William Davis (0) Chad is a 43-year old father of five kids. Earlier this year, he developed chest pain that got worse and worse. He ended up with a total of five stents in all three coronary arteries. After a devastating experience with Lipitor that resulted from a ruptured tendon, he came to me for an option. Chad's lipoproteins:
Slow Burn works 14. December 2010 William Davis (55) I have been impressed with the results I've been obtaining with Fred Hahn's Slow Burn strength training technique. Because I have limited time to hang around the gym, any technique that provides outsized results in a limited amount of time, I have to admit, appeals to me. In past, I'd be lucky to squeeze in one or two strength training sessions per week, devoting the rest of the time to biking outdoors, biking on a sedentary bike (while playing XBox), jogging, or doing strenuous yard work like digging trenches and planting shrubs. Over the years, I've gradually lost muscle, since the strength training effort suffered with my time limitations. So Fred's time-efficient Slow Burn idea struck a chord. Having now done it with some regularity, usually 1-2 times per week since mid-September, I have gradually added back visible muscle. My Slow Burn workouts, involving 8-10 different movements, seem to have restored the muscle I've lost, with a very modest time effort.It took a little getting used to. After Fred showed me how to do the movements--slow motion movement in both the "positive" and "negative" directions, with smooth, non-jerking transitions, one set per muscle group, each taken to muscle exhaustion--it left me unusually tired and sore the next day. This surprised me, given the limited time involved. Breathing is also very important; the usual exhale-during-the-positive, inhale-during-the-negative pattern is replaced by breathing freely during the entire set. I didn't get this at first and ended up with headaches that got worse with each set. Breathing freely relieved me from the effect. I have strength trained since I was around 15 years old. Back in the early 1970s, I had about 2000 lbs of barbells and dumbbells in my garage in New Jersey, while also driving back and forth to the Morristown, NJ, YMCA to train with friends. The Slow Burn movements forced me to break habits established over nearly 40 years of conventional strength training. I've also played around with mixing conventional movements with Slow Burn movements to keep it fresh. This also seems to work. If you're interested in giving it a try, here's an animation that demonstrates what Slow Burn movements look like. Fred has also produced an excellent 3-DVD set of videos that more fully describe the practice.
Do your part to save on healthcare costs 13. December 2010 William Davis (37) While many of the factors that drive the relentless increase in health care costs are beyond individual control, you are still able to exert personal influence over costs. Just as in political elections, your one vote alone may not count; it's the collective effort of many people who share similar opinions that results in real change.I just got the new monthly premium for my high-deductible health insurance: Up $300 per month, putting my family's total premium over $2000 per month---for four healthy people. (My son fractured his wrist playing high school hockey earlier this year; that may explain at least some of the increase.) I'm going to shop around for a better deal. However, shopping is likely to only stall the process. It will not address the systemic problems with healthcare that continue to drive premiums up and up and up. So what can you do to help keep costs down? Here are a few thoughts:Never accept a prescription for fish oil, i.e., Lovaza. Just buy far less costly over-the-counter fish oil. I treat complex hyperlipidemias, including familial hypertriglyceridemia, ever day. I NEVER use prescription fish oil. A typical 4 capsule per day Lovaza prescription adds around $280 to $520 per month to overall health costs (though your direct out-of-pocket costs may be less, since you shove the costs onto others in your plan). Never accept a prescription for vitamin D. Prescription vitamin D is the mushroom or invertebrate form anyway. Just buy the human (cholecalciferol, D3) form from your health food store or "big box" store. They yield consistent increases in 25-hydroxy vitamin D levels, superior to the prescription form. And they're wonderfully inexpensive.Eliminate wheat from your diet. If there is a dietary strategy that yields unexpected and outsized benefits across a wide spectrum of health, it's elimination of this thing we're sold called "wheat," you know, the genetically-transformed, high-yield dwarf mutant that now represents 99% of all wheat sold. Blood sugar drops, pre-diabetics become non-prediabetics, diabetics reduce need for medication or become non-diabetic, cholesterol values plummet, arthritis improves, acid reflux and irritable bowel symptoms improve or disappear, just to mention a few. Wheat elimination alone, I believe, would result in incalculable savings in both healthcare costs and lives saved. Be sure to obtain iodine. In the fuss to cut salt use, everyone forgot about iodine. Lack of iodine leads to thyroid disease, usually hypothyroidism, that, in turn, causes cholesterol values to increase, weight to increase, and heart disease risk to double, triple, or quadruple. Iodine supplementation is easy and wonderfully inexpensive. Over time, I hope that all of us can help develop the effort to self-direct more and more of our own health. Our Track Your Plaque program has shown me that, not only can people take the initiative to direct aspects of their own health, they can do it better than 99% of doctors. I'm sure there are many, many other ways to help reduce costs. Any suggestions?
Fish oil: What's the difference? 10. December 2010 William Davis (27) Ultra-purified, pharmaceutical grade, molecularly distilled. Over-the-counter vs. prescription. Gelcap, liquid, emulsion. There's a mind-boggling variety of choices in fish oil today. A visit to any health food store, or any "big box" store for that matter, will yield at least several, if not dozens, of choices, all with varying and often extravagant claims of purity and potency.So what's the real story? Given the analyses conducted over the years, along with my experience with dozens of different preparations, I believe that several conclusions can be reached about fish oil:Fish oil is free of contamination with mercury, dioxin, PCBs, or furans. To my knowledge, only one fish oil preparation has been found to have a slight excess of PCBs. (This is different from cod liver oil that has been found by one source to have a slight excess of PCBs.)Oxidative breakdown products differ among the various brands. Consumer Lab (http://www.consumerlab.org/), for instance, has found that several widely available brands of fish oil contained excessive oxidative breakdown products (TOTOX). You can perform you own simple test of oxidative breakdown products: Sniff it. Your fish oil should pass the "sniff test." High quality fish oil should smell non-fishy to lightly fishy. Rancid fish oil with excessive quantities of oxidative breakdown products will smell nasty fishy.FDA approval does not necessarily mean greater potency, purity, or effectiveness. It just means that somebody assembled the hundreds of millions of dollars to obtain FDA approval, followed by lots of marketing savvy to squash the competition.This means that there are a number of excellent fish oil products available. My favorites are the liquid fish oils from Pharmax, Nordic Naturals, and Barleans. Capsules from Carlson, PharmaNutrients, and Fisol have also performed consistently. The "big box" capsules from Sam's Club and Costco have also performed well and are wonderfully affordable.
Wheat-free pie crust 9. December 2010 William Davis Toggle navigation Home Blog Home Archive Join Now Site normal Se connecter Can I see your linea alba? 2. novembre 2010 William Davis (19) As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba. Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen. It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors. Can you see your linea alba? Dwarf mutant wheat 31. octobre 2010 William Davis (13) Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant. Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to. The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans. Medical education in the days of Big Pharma 30. octobre 2010 William Davis (43) I received this detailed email from an unexpected source: a 3rd-year medical student.In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life. Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat. While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career. Dr. Davis,I am a 3rd year medical student at ________ University. I came across your blog today, and I'm very glad I did. I appreciate the value of your time, so I want to be as succinct as possible while still getting across what I'm really thinking and feeling:From what I gathered exploring your blog for a while this afternoon, the wellness strategies you incorporate into your practice are some of the exact things I want to do with my future patients. Personally, I strongly believe in staying healthy by eating right, staying active, etc. For instance, I don't eat grains or much in the way of starches and sugars. So I love the fact that you are helping your patients make these powerful and foundational changes in their lives.As I'm sure was your experience, a full appreciation of nutrition and lifestyle as a first-line health strategy is not something that was taught to me in medical school. I came to school with this deep conviction already in my heart and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss as to how I'm going to be able to practice medicine the way I want to, which is to incorporate these all-important principles into the care of my patients.What I've come to understand about the medical field today is that the information that exists is primarily subsidized by the pharmaceutical industry, and dictated to medical professionals as "evidence-based" treatment guidelines and recommendations by organizations with sincere and official sounding names like American Heart Association and American Cancer Society. Add to that the pressure of potential malpractice litigation and the complexities of the insurance reimbursement game, and it seems to me like what you get is a bunch of diagnostic and medication management algorithms that any half-trained monkey could follow. In his sleep. Which I guess would be alright if at least they weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma, Food Inc, insurance conglomerates, and agri-politics (I think I just made that word up.) A lot of well-intentioned physicians are just parroting the party line, as their patients dutifully and gratefully chomp down their statins and diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes education" programs with curriculum put together by drug companies? How is that even legal? Massive corporations raking in massive profits that are dependent on uncontrolled blood sugars telling people how to best control their blood sugars?!Anyway, forgive my rant. What I'm getting at is this: How can I practice medicine, with the freedom to educate/coach/treat my patients with diet and lifestyle changes to mitigate/reverse their chronic health conditions? Without feeling like I automatically have to first and foremost prescribe the litany of drugs dictated by "evidence-based" guidelines? Without excessive fear of litigation or loss of credibility among my peers? Without having to lie through my teeth to my patients, and tell them that eating low-fat and heart-healthy whole grains is the best way (implication also being the only scientifically proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?I want my patients to have the full benefit of honest nutrition and lifestyle information, and medications and surgery as necessary. I'm afraid that there isn't room for this kind of holistic emphasis in the medical profession today. Are there residencies that include this kind of training or at least respect these "unconventional" philosophies? Are there clinics or practice groups that would allow me to practice with this emphasis, or is there a bias against docs who do not necessarily conform to the party position? Will I have no other option but to go it alone under the auspices of my own shingle? How do you handle these kinds of issues in your professional life?Sincerely,Theresa M. A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets. I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often. The Great Low-Carb Connector 28. octobre 2010 William Davis (15) The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible. New Track Your Plaque record! 27. octobre 2010 William Davis (19) The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score. Well, the longstanding record was broken this week: 75% reduction in score. At the start, Freddie has disastrous lipid values:LDL cholesterol 263 mg/dlHDL 26 mg/dlTriglycerides 323 mg/dlTotal cholesterol 354 mg/dlLipoproteins (NMR) were worse:LDL particle number 3360 nmol/LSmall LDL 2677 nmol/LHeart scan score: 732Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable. Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me. Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight. 43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction. While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees. The Anti-AGEing Diet 22. octobre 2010 William Davis (36) Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck. There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others. One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)There are two general ways to develop AGEs:1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months. A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation. 2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi. The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation. Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food. If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy. The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs. Butter: Just because it's low-carb doesn't mean it's good 21. octobre 2010 William Davis (59) The diet I advocate in the Track Your Plaque program to gain control over the factors that lead us to coronary plaque and heart attack is a low-carbohydrate diet. We begin with elimination of wheat, cornstarch, oats, and sugars in the context of an overall carbohydrate-reduced diet. We refine the program by monitoring postprandial (after-meal) glucoses. But not everything low-carb is good for you. Fried sausages, for instance, are exceptionally unhealthy, despite having little to no carbohydrates. An emerging but potentially very powerful issue is that of Advanced Glycation End-products, or AGEs. There are two general varieties of AGEs: endogenous (formed within the body) and exogenous (formed in food that is consumed). Endogenous AGEs form in the body as a result of high blood glucose, i.e., glycation. When exposed to any blood glucose level of 100 mg/dl or greater, some measure of glycation will develop due to a reaction between glucose and various proteins, e.g., proteins in the lens of the eye, forming cataracts over time. Exogenous AGEs form in food, generally as a result of heating to high-temperature. (AGEs is really a catch-all term; there are actually a number of reactions that occur in foods, not all of them involving sugars. However, the "AGE" label is used to signify all the various related compounds. The values quoted here are from Dr. Helen Vlassara's Mt. Sinai Hospital laboratory; reference below.) Beef cooked to high-temperature yields plentiful AGEs. One gram of roast beef, for instance, contains 306,238 units. This means that an 8-oz serving yields 13.8 million units AGEs. Compare this to a boiled egg with 573 units per gram, raw tomato with 234 units per gram. Butter contains an impressive 264,873 units AGEs per gram, the highest content per gram in the entire list of 250 foods tested in the Mt. Sinai study. A couple pats of butter (10 g) therefore contains 2.64 million units. A stick of butter that you might add to cake batter to make a cake therefore yields 30 million units of AGEs. So there's nothing wrong with the fat of butter. It's AGEs that appear to be responsible for the endothelial dysfunction/artery-constricting, insulin-blocking, oxidation and inflammation reactions that are triggered. Among all of our food choices, butter is among the worst from this viewpoint. Throw in the peculiar "insulinotrophic" effect of butter, and you have potent distortion of metabolic pathways, courtesy of the butter on your lobster. (AGE data from Goldberg 2004. In this analysis, carboxymethyllysine was the marker used for AGE content.)Incidentally, the new Track Your Plaque diet will soon be released as chapter 9 of the new Track Your Plaque book on the website. Einkorn now in Whole Foods 16. octobre 2010 William Davis (19) I just saw this at Whole Foods: einkorn pasta. In my einkorn bread experience (In search of wheat: We bake einkorn bread), I was spared the high blood glucose and neurologic and gastrointestinal effects of conventional whole wheat grain (dwarf Triticum aestivum). I shared the einkorn bread with four other people with histories of acute wheat sensitivities, only one of whom experienced a mild diffuse joint reaction, the other three not experiencing any symptoms. Anyone wishing to try einkorn can now obtain commercial pasta from Jovial, an Italy-based manufacturer. It comes in spaghetti, linguine, rigatoni, fusilli, and penne rigate shapes. Eli Rogosa, founder of The Heritage Wheat Conservancy, tells me that, in her experience, celiac suffers seem to not experience immunologic phenomena triggered by conventional wheat. However, we've got to be careful here. The so-called ("diploid") "A" genome of einkorn shares many of the same genes as the ("hexaploid") "ABD" genomes of modern wheat, including overlap in the sequences coding for the 50-or so different glutens and glutenins. Most of the genes that code for the glutens that cause celiac and related illnesses reside in the "D" genome that are absent in the einkorn "A" genome. However, the "A" genome still codes for glutens. So there is potential for activating celiac disease in some people. Insufficient research has been devoted to this question. It is a question of extreme importance to people with celiac and other immune-mediated conditions, since re-exposure to the wrong form of gluten can increase risk of intestinal lymphoma 77-fold, as well as risk of other gastrointestinal cancers. So einkorn should not be viewed as a cure-all for all things wheat, but as something to consider for a carbohydrate indulgence. Yes, indeed: It is a carbohydrate, with 61 grams ("net") carbs per 4 oz (uncooked) serving. Should anyone give it a try, please be sure to report back your experience, especially if you have a history of wheat intolerance. If you have a glucose meter, pre- and 1-hour post values are the ones to measure to gauge the blood sugar effects of consumption. Because pasta tends to cause long sustained blood sugar rises, another value at 2-4 hours might be interesting. Noodles without the headaches 14. octobre 2010 William Davis (26) If you are looking for a wheat-free noodle or pasta, shirataki noodles are worth a try. Shirataki noodles are low-carbohydrate (less than 3 g per 8 oz package) and, of course, do not trigger all the unhealthy effects of wheat--no blood sugar/insulin provocation, no addictive brain effects (exorphins), no gluten-mediated inflammatory effects. (I advise avoiding gluten-free pasta alternatives made with rice flour and other common gluten alternatives, since they trigger blood sugar, small LDL, and growth of visceral fat just like wheat.)I made a stir-fry using the shirataki-tofu noodles, shown below. (Tofu is added to make the noodles more noodly in consistency, as opposed to the chewier non-tofu variety.) The noodles were a lot like the ramen I used to eat as a kid. They were filling and tasted great in the sesame oil, soy sauce, tofu, and vegetables I used. The noodles are easy to use. Just drain liquid out of package. (The noodles come in water.) Rinse in collander 30 seconds, then boil for 3 minutes. Add to your stir-fry or other dish. Some manufacturers, such as House Foods, also have angel hair and fettucine style noodles. You're fried 13. octobre 2010 William Davis (26) If I could invent a food that illustrates nearly all of the shortcomings of the American diet, it would be French fries, the familiar fixture of fast food. What we have come to view as French fries contain just about every one of the unhealthy ingredients that lead us down the path of obesity, diabetes, heart disease, high blood pressure, etc. Let's take them one by one:Potato starch--Potato starch exerts an effect on blood sugar similar to that of table sugar, only worse. (Glycemic index french fries 75; glycemic index sucrose 65.) Advanced Glycation End-products (AGEs)--AGEs form when proteins and fats are subjected to high temperature cooking; the longer the high temperature, the more the food reaction creating AGEs proceeds. AGEs are the likely culprit in roasted and fried foods that made it appear that saturated fats were bad, when it was really AGEs all along. AGEs have been shown to block insulin's effects, increase blood sugar, cause endothelial dysfunction and high blood pressure.Acrylamides--Acrylamides, like AGEs, are created through high-temperature heating. French fries are unusually rich in AGEs. Brewed coffee also contains a small quantity, while French fries contain 82-fold greater quantities, among the highest of all known sources of acrylamides.Oxidized oils--The amount of oxidized oils will depend on what sort of oil was used for frying. As more restaurants are trying to get away from hydrogenated oils, many are turning back to polyunsaturates. Others are turning to commercial-grade oils that contain both hydrogenated and polyunsaturates. If oils are permitted to oxidize, then they will trigger oxidative phenomena in your body upon consumptions, e.g., LDL oxidation (Staprans 1994).In other words, the innocent appearing French fry unavoidably triggers oxidation, all the phenomena triggered by high blood glucose (high insulin, glycation, visceral fat accumulation), along with the cascade of effects arising from AGEs and acrylamides.Top your French fries with some ketchup made with high-fructose corn syrup that exagerrates AGE formation, visceral fat, and distorts postprandial (after-eating) effects. Is it any wonder that we've lost control over diet? << Articles précédents Articles suivants >> Articles suivants12...181920212223242526...123124Articles précédents All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in Who knows what 4. September 2008 William Davis (4) You know that cynical old saying:It’s not what you know, it’s who you know. In other words, knowing the right person provides you strategic advantage in business, social advancement, etc. In health, it was often true. Knowing who the better doctors were, for instance, in your city might provide you with access to better care. Enter the Information Age. You now have access to medical information equal to that of your doctor. You now have access to patient discussions about doctors, their practices, their performance records. There is now a depth and breadth of information on health that was never available before. I’d therefore turn the old saying into the new Health 2.0 version:It’s not who you know, it’s what you know.In health, information now reigns supreme, not knowing somebody else who has the right connections. Positive: Everybody now theoretically has access to an equal amount of information, since you can access information on any topic just as easily as I can. Negative: It puts more of the burden on you. If you screw up in health, perhaps you didn’t try to get the best information hard enough. I love this new development, this emergence of empowerment in health. I call it self-directed health, the individual capacity to exert enormous influence over the quality of your healthcare. This is obviously a work in progress. All the answers and tools for self-directed care, self-empowerment are not yet available, some haven’t even yet been imagined. But they are coming. “Too many false positives” 4. September 2008 William Davis (6) “Do you really think I need a heart scan?” asked Terry. “My doctor said that heart scans show too many false positives. He says that many people end up getting unnecessary heart catheterizations because of them.” At age 56, Terry was becoming increasingly frightened. His father had suffered his first heart attack at age 53, Terry’s paternal uncle had a heart attack at age 56, his paternal grandfather a heart attack at age 50. Is this true? Do heart scans yield too many false positives, meaning abnormal results when there really is no abnormality?No, it is not. What Terry’s doctor is referring to is the fact that, in the decades-long process that leads to heart attack, heart scans have the ability to detect early phases of developing coronary atherosclerotic plaque. Let’s take Terry’s case, for example. Given his family history, it is quite likely that he does indeed have coronary atherosclerotic plaque. Will it be detectable by performing a stress test? Probably not. In fact, Terry jogs and feels well while doing so. While a stress test abnormality that fails to reach conscious perception is possible, it’s fairly unlikely given his exercise routine. Will Terry’s coronary atherosclerotic plaque be detectable by heart catheterization? Very likely. But why perform an invasive hospital procedure just as a screening test? Should a woman wishing to undergo a screening test for breast cancer undergo breast removal? Of course not. Is waiting for symptoms a rational way to approach diagnosis of heart disease? Well, when symptoms appear, it means that coronary blood flow is reduced. Stents and bypass surgery may be indicated. The risk of heart attack and death skyrocket. Sudden death becomes a real possibility. In the 30 or so years required to establish sufficient coronary plaque to permit the appearance of symptoms or the development of an abnormality detectable by stress testing, there were many years when the disease was early--too early to generate symptoms, too early to be detectable by stress testing. That’s when heart scans uncover evidence for silent coronary atherosclerotic plaque.Should we call this a “false positive” just because it doesn’t also correlate with “need” for a catheterization, stent, bypass operation or result in heart attack within the next few weeks? The detection of early plaque is just that: early disease detection. Imagine, for instance, that the breast cancer that will grow into a palpable nodule or mass detectable by mammogram is detectable by a special breast scan 15 years before it becomes a full-blown tumor, metastasizing to other organs. What if effective means to halt that earliest evidence of cancer could put a stop to this devastating disease decades ahead of danger? Is this a “false positive” too?In my view, this is the knuckleheaded thinking of the conventional practitioner: “Don’t bother me until you’re really sick.” Prevention is a practice that has become fashionable only because of the push of the drug industry. Nutrition is an afterthought, a message conceived through consensus of “experts” with suspect motivations and allegiances. So, no, heart scans do not uncover “false positives.” They uncover early disease--true positives--years before it is detectable by standard tests or by the appearance of catastrophe. But that is the whole point: Early detection means getting a head start on prevention.Do heart scans lead to unnecessary heart catheterizations? Yes, sadly they do. But not because heart scans are false positive. It happens because of unscrupulous or ignorant cardiologists who use the information wrongly. In my view, heart scans should NEVER lead directly to heart catheterization in an asymptomatic patient. Heart scans, as helpful as they are, do not modify the standard reasons for performing heart procedures. If a car mechanic is dishonest and fixes a carburetor that didn't need fixing, should we condemn all car mechanics? No, of course not. We only need to develop the means to weed out the bad apples. The same applies to heart scans. Triglycerides divided by five 3. September 2008 William Davis (8) Here's a bit of lipid tedium that might nonetheless help you one day decipher the meaning of shifts in your cholesterol panel. Recall from prior discussions that conventional LDL cholesterol is a calculated value. Contrary to popular opinion, LDL is usually not measured, but calculated from the Friedewald equation:LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5For the sake of simplicity, let's call total cholesterol TC; HDL cholesterol HDL, and triglycerides TG. We've also talked in past how a low HDL makes calculated LDL inaccurate, sometimes wildly so. (See Low HDL makes Dr. Friedewald a liar.)Here's yet another source of inaccuracy of the Friedewald-calculated LDL: any increase in triglycerides.Let's say, for instance, that starting lipid panel shows:TC 170 mg/dlLDL 100 mg/dl HDL 50 mg/dlTG 100 mg/dlYou're advised to follow a standard low-fat, whole grain-rich diet advocated by "official" agencies (the diet I bash as knuckleheaded). Another panel a few months later shows:TC 230 mg/dlLDL 140 mg/dlHDL 50 mg/dlTG 200 mg/dl(Obviously, I've oversimplified the response for the sake of argument. HDL would likely go down, LDL would change more depending on body weight, small LDL tendencies, and other factors. You'd also likely get fat.) Now your doctor declares that your LDL has gone up and you "need" a statin agent. Nonsense, absolute nonsense. What has really happened is that the increased dietary intake of wheat and other "healthy whole-grain foods" has caused triglycerides to skyrocket. LDL increases, in turn, by a factor of TG/5, or 40 mg/dl. Thus, LDL has been inflated by the triglyceride-raising effect of whole grains. This is yet another reason why the standard lipid panel, full of hazards and landmines, needs to be abandoned. But calculated LDL in particular is an exercise in frustration. Though the example used is hypothetical, I've witnessed this effect thousands of times. I've also seen many people placed on statin drugs unnecessarily, due to the appearance of a high LDL cholesterol that really represented increased TG/5, usually induced by an excessive carbohydrate intake, including those commonly misrepresented as healthy such as whole grains. Who reads The Heart Scan Blog? 2. September 2008 William Davis (0) In the Heart Scan Blog, I am often guilty of speaking out loud of my varied thoughts on this crazy thing that we've created called the cardiovascular healthcare machine. But I discuss it in the context of asking "How could this be done better--better outcomes, more patient-friendly, more accessible . . . more do-it-yourself? The last part is the part that throws most people. Do-it-yourself? My colleagues would claim I'm nuts, suggesting that coronary heart disease is something manageable by yourself. In the conventional pathway, after all, coronary disease is that unpredictable, poorly detected by standard tests, condition that then leads to heart catheterization, stents, bypass , and the like. Several factors distinguish the readers of The Heart Scan Blog that surprised me:--Nearly 60% are women--There are a disproportionate number of Asian people. (Can someone explain this to me?) --A great number have graduate degreesI believe this tells me that The Heart Scan Blog appeals to a somewhat more sophisticated audience. This, to some degree, warms my heart, since it means that I've captured the attention of some people who may be more discriminating and thoughtful in their Internet surfing. However, I also lament the fact that these conversations are not achieving the mainstream. After all, Kitchen sink approach for Lp(a) 29. August 2008 William Davis (12) Lipoprotein(a), Lp(a), can be a tough nut to crack. Having struggled and wrestled with this genetic pattern for the last 12 years or so in hundreds of patients, I have gained great respect for this difficult to control pattern. I regard lipoprotein(a) as the number one most aggressive cause for heart disease and coronary plaque known. It can account for heart attacks in men in their 40s, women in their 50s. It can cause heart disease and heart attacks in even the ultra-fit like marathon runners. It accounts for both excessive coronary risk and misleading cholesterol values in slender, healthy-appearing people. Niacin is the number one treatment choice for Lp(a), followed by testosterone for men, estrogens (preferably human, not horse or other non-human mammal) for women. I then often resort to DHEA, along with adjunctive nutritional agents like raw almonds, ground flaxseed, and others. Our most recent addition to the Lp(a) treatment list is high-dose fish oil, which appears to exert a significant effect in about 40% of people with Lp(a). Even with this multi-agent approach, not everybody gains control over Lp(a).That makes me wonder if someone has Lp(a) at a substantial level of, say, 200 nmol/L or 70 mg/dl (values can differ tremendously, depending on the method of measurement), should we throw everything but the kitchen sink at Lp(a) from the start? Right now, by adding an agent one at a time, it often takes two years to gain control over Lp(a) (if we are going to get it at all).While many people might find this unpalatable and overwhelming from the starting gate of their program, I do believe it may be a strategy we should consider adopting for full and more immediate plaque control in the Track Your Plaque program. Something to chew on. Clearly, we need better answers for Lp(a). A "kitchen sink," full-frontal assault might be a way to gain faster control, though not necessarily a superior approach with regards to efficacy and potency. There are a number of unique, potentially effective therapies for Lp(a) that are worth examining. Given the difficulty of performing clinical trials with non-drug agents (largely a lack of financial support, since nobody gets a financial return with non-patent-protectable agents), I am anxious to put these potential treatments to a test in the Track Your Plaque program Virtual Clinical Trail (VCT). The VCT gives us a quick and relatively easy method to test various potential treatments, with feedback generated in months, rather than years. Any suggestions on promising agents to test? Of course, they must be widely available nutritional agents, not drugs. Making Dr. Friedewald an honest man 28. August 2008 William Davis (3) Colleen started with the usual discrepancy between conventional calculated LDL cholesterol of 121 mg/dl and the far more accurate LDL particle number (NMR) of 1927 nmol/L. Those of you following this conversation or our many conversations on the Track Your Plaque Forum know that a useful and highly reliable rule-of-thumb for converting NMR LDL particle number to LDL is to drop the last digit: 1927 nmol/L becomes 192 mg/dl. (This is, admitttedly, arrived at empirically, not by design. However, it has held up through thousands of NMR analyses and plays out reasonably when you compare distributions of Friedewald LDL and LDL particle number on a population basis.)In other words, by this simple manipulation, Colleen's Friedewald calculated LDL is off by 58%. This is very common, a phenomenon I witness several times every day. By LDL particle size, 75% of all Colleen's LDL particle were abnormally small (small LDL particle number 1440 nmol/L). This is a moderately severe small LDL tendency.So we took all the steps for reduction of small LDL/LDL, including elimination of wheat and cornstarch, exercise, weight loss (which happens inevitably when wheat and cornstarch are eliminated), fish oil, vitamin D, etc. Another NMR lipoprotein panel showed an LDL particle number of 882 nmol/L and a Friedewald calculated LDL of 87 mg/dl. Using our rule-of-thumb, LDL by particle number is virtually the same as the calculated LDL. This time, small LDL numbered only 237 nmol/L, or 26.8% of the total, a marked reduction. Isn't that interesting? As small LDL is corrected, the crude Friedwald calculated LDL approximates the more accurate LDL particle number. It assumes that accuracy of the Friedewald calculation may be more likely to occur as LDL size approaches normal. However, when LDL size is abnormally small--a condition shared by at least 70% of people with coronary heart disease--then the Friedewald LDL becomes increasingly inaccurate.The opposite can also happen: When all or nearly all LDL particles are large, Friedewald calculated LDL can markedly overestimate LDL particle number. Yesterday, for instance, a patient had a Friedewald calculated LDL of 183 mg/dl, but an NMR particle number of 1110 nmol/L--drop the zero . . . LDL 110 mg/dl. This woman was advised to take a statin drug by her primary care physician, based on the Friedewald LDL. Instead, she proved to have a far lower LDL. She would not have benefitted from taking a statin drug. As I've warned many times before: Beware the Friedewald calculated LDL. Some basic vitamin D issues 24. August 2008 William Davis (7) The last post on vitamin D raised a number of basic questions among readers. So let me discuss some of these questions one by one. All of them raise important issues surrounding the practical aspects of managing vitamin D in your health. Anne said:I think it is important to stress that vitamin D supplementation needs to be continued long term. I have met too many people who have been prescribed 50,000 IU of D2 for 8-12 weeks and then told to stop because their 23(OH)D went over 30ng/ml. I know one person who's doctor stopped and started the D2 3 times. Thanks for pointing that out, Anne. Excellent point. I also see doctors do this with statin drugs: start it, check a LDL level which is lower, then think that you're done and stop the drug. What the heck are they thinking? If vitamin D is not being produced by sun exposure and not obtainable through diet, continued supplementation is necessary, essentially for life. Twinb asked:How often you think Vit. D levels should be tested after the initial test is done, especially if the levels are drastically low?We have used every 6 months in the office. Ideally, levels are in mid-summer and mid- to-late winter in order to gauge the extremes of your seasonal fluctuations. While most adults over 40 fail to fluctuate more than 10 ng/ml in the Wisconsin climate (and this summer, after an initial rainy season early, has been flawlessly bright and sunny, in the high-70s and 80s every single day for months), an occasional person fluctuates more widely. The only way to judge is to check a blood level. Rich said:Vitamin D dosage effects appear to be quite idiosyncratic.Yes, indeed it is. Despite using crude rules-of-thumb, like taking 1000 units of vitamin D per 10 ng/ml desired (a rule I learned from Dr. John Cannell, which he offered fully aware of its inaccuracy), many people will surprise you and have levels that make no sense. Testing is crucial to know your vitamin D level. Richard asked: Where do we get enough vitamin D wihout worring about laboratory tests? Well, the entire point of the post was that you absolutely, positively cannot just take vitamin D blindly at any dose and hope that your level is ideal, no more than you can blindly take a dose of thyroid and know you have achieved normal thyroid levels. In my view, vitamin D blood levels are an absolute. Another simple issue: Don't be afraid of vitamin D. It is, in all practicality, no more dangerous than getting a dark tan. (But, as many of you realize, getting a tan is no assurance of raising vitamin D if you are over 40 years old.)Wouldn't it be great if someone developed a do-it-yourself-at-home skin test for vitamin D? I know of no effort to develop this, but it would be a huge advantage for all of us. “How much vitamin D should I take?” 22. August 2008 William Davis (17) It’s probably the number one most common question I get today: “How much vitamin D should I take?”Like asking for investing advice, there are no shortage of people willing to provide answers, most of them plain wrong. The media are quick to offer advice like “Take the recommended daily allowance of 400 units per day,” or “Some experts say that intake of vitamin D should be higher, as high as 2000 units per day.” Or “Be sure to get your 15 minutes of midday sun.”Utter nonsense. The Food and Nutrition Board of the Institute of Medicine has been struggling with this question, also. They have an impossible job: Draft broad pronouncements on requirements for various nutrients by recommending Recommended Daily Allowances (RDA) for all Americans. The Food and Nutrition Board has tried to factor in individual variation by breaking vitamin D requirements down by age and sex, but what amounts to a one-size-fits-nearly-all approach. Much of the uncertainty over dosing stems from the fact that vitamin D should not be called a “vitamin.” Vitamins are nutrients obtained from foods. But, outside of oily fish, you'll find very little naturally-occurring vitamin D in food. (Even in fish, there is generally no more than 400 units per 4 oz. serving.) Sure, there’s 20 units in an egg yolk and you can activate the vitamin D in a shiitake mushroom by exposing it to ultraviolet radiation. Dairy products like milk (usually) contain vitamin D because the USDA mandates it. But food sources hardly help at all unless you’re an infant or small child. It all makes sense when vitamin D is viewed as a hormone, a steroid hormone, not a vitamin. Vitamin-no, steroid hormone-D exerts potent effects in tiny quantities with hormone-like action in cells, including activation of nuclear receptors. It is the only hormone that is meant to be activated by sun exposure of the skin, not obtained through diet. But the ability to activate D is lost by the majority of us by age 40 and even a dark tan is no assurance that sufficient skin prohormone D activation has taken place. As with any other hormone, such as thyroid, parathyroid, or growth hormones, dose needs to be individualized. Imagine you developed a severely low thyroid condition that resulted in 30 lbs of weight gain, lose your hair, legs swell, and heart disease explodes. Would you accept that you should take the same dose of thyroid hormone as every other man or woman your age, regardless of your body size, proportion of body fat, metabolism, genetics, race, dietary habits, and other factors that influence thyroid hormone levels? Of course you wouldn’t. Then why would anyone insist that vitamin D be applied in a one-size-fits-all fashion? (There’s another world in which a one-size-fits-all approach to hormone replacement has been widely applied, that of female estrogen replacement. In conventional practice, there’s no effort to identify need, estrogen-progesterone interactions, nor assess the adequacy of dose, not to mention the perverse non-human preparation used.) With thyroid hormone, ideal replacement dose of hormone ranges widely from one person to another. Some people require 25 mcg per day of T4; others require 800% greater doses. Many require T3, but not everybody. Likewise, vitamin D requirements can range widely. I have used anywhere from 1000 units per day, all the way up to 16,000 units per day before desirable blood levels were achieved. Vitamin D dose needs to be individualized. Factors that influence vitamin D need include body size and percent body fat (both of which increase need substantially); sex (males require, on average, 1000 units per day more than females); age (older need more); skin color (darker-skinned races require more, fairer-skinned races less); and other factors that remain ill-defined. But these are “rules” often broken. My office experience with vitamin D now numbers nearly 1000 patients. The average female dose is 4000-5000 units per day, average male dose 6000 units per day to achieve a blood level of 60-70 ng/ml, though there are frequent exceptions. I’ve had 98 lb women who require 12,000 units, 300 lb men who require 1000 units, 21-year olds who require 10,000 units. (Of course, this is a Wisconsin experience. However, regional differences in dosing needs diminish as we age, since less and less vitamin D activation occurs.)Let me reiterate: Steroid hormone-vitamin D dose needs to be individualized. There’s only one way to individualize your need for vitamin D and thereby determine your dose: Measure a blood level. Nobody can gauge your vitamin D need by looking at you, by your skin color, size, or other simple measurement like weight or body fat. A vitamin D blood level needs to be measured specifically-period. Unfortunately, many people balk at this, claiming either that it’s too much bother or that their doctor refused to measure it. I would rank normalizing steroid hormone-vitamin D as among the most important things you can do for your health. It should never be too much bother. And if your doctor refuses to at least discuss why he/she won’t measure it, then it’s time for a new doctor. If you’re worried about adding to rising healthcare costs by adding yet another blood test, think of the money saved by sparing you from a future of cancer, heart disease, osteoporosis, diabetes, etc. The cost of a vitamin D blood test is relatively trivial (around $40-50, a fraction of the cost of a one month supply of a drug for diabetes.) So how much vitamin D should you take? Enough to raise your blood level of 25-hydroxy vitamin D to normal. (We aim for a normal level of 60-70 ng/ml.) You probably don't take enough fish oil 20. August 2008 William Davis (17) The results of the recent Heart Scan Blog survey in response to the question: MY DAILY DOSE OF EPA + DHA FROM FISH OIL IS revealed:Zero--I don't take any 17 (7%) of respondents Less than 1000 mg per day 24 (10%) of respondents 1000-2000 mg per day 91 (38%) of respondents 2000-3000 mg per day 44 (18%) of respondents 3000-4000 mg per day 40 (16%) of respondents More than 4000 mg per day 20 (8%) of respondentsBased on the above results, I would say that only a minority of respondents are taking an ideal dose of omega-3 fatty acids. Nearly all of us should consider taking more. Benefits of omega-3 fatty acids (EPA + DHA) from fish oil begin around a dose of 840 mg per day, according to the GISSI Prevenzione Trial of 1999, an 11,000-participant trial. This dose also corresponds to a quantity of omega-3s that have been shown to raise EPA + DHA blood levels and thereby reduce the notoriously high AA:EPA ratio of Americans. But what dose is sufficient? What dose is ideal? Well, the answer to a great degree depends on what you are taking the fish oil for. If being taken to reduce triglycerides and triglyceride-containing lipoproteins, like VLDL and the after-eating (postprandial) IDL, then a higher dose will be necessary. (Triglyceride reduction for the genetically-determined very high triglyceride level of familial hypertriglyceridemia is the FDA-approved indication for prescription Lovaza.) If you are taking fish oil for treatment of ADHD, depression, or bipolar illness, very high doses are often necessary. But how about maximal reduction of cardiovascular risk and for control or reversal of atherosclerotic plaque? This conversation is still evolving. But we can learn some important lessons from three populations of the world that are vigorous consumers of fish:--The Inuits (aka Eskimos) of Greenland and northern Canada--The Japanese--The Bantus of Tanzania who live along Nyasa LakeAll three indigenous populations have several-fold greater intakes of fish and omega-3 fatty acids, have higher blood levels of omega-3 fatty acids, and have enjoyed reduced cardiovascular events, reduced atherosclerotic plaque, or improvement in various surrogates of cardiovascular risk (e.g., Lp(a)). The most recent addition to this conversation is the ERA JUMP Study, discussed in a previous Heart Scan Blog post. In ERA JUMP, despite being heavy smokers and having other markers for greater risk for heart disease, Japanese men living in Japan had markedly less carotid and coronary plaque, as compared to Caucasian men living in PIttsburgh or Hawaiian men of Japanese descent. The difference appeared to be attributable to serum levels of omega-3 fatty acids. I believe that the trend is here is to increase the amount of omega-3 fatty acids that most of us take. In the Track Your Plaque program, we have been advocating a rock-bottom starting dose of EPA + DHA of 1200 mg per day. However, I believe that this is due for a change. We will be increasing the minimum dose for plaque regression and control. Please attend our Webinar this evening for a full, in-depth discussion of the rationale behind this important change. As always, let me remind you that I am not selling, nor ever have sold, fish oil supplements. If I advocate a specific dose, a higher dose, I do so based on my interpretation of the data and experience with patients, not because I am interested in selling brand X of fish oil. Vitamin D and HDL 19. August 2008 William Davis (23) Despite the paucity of scientific documentation of this phenomenon, I am continuing to witness extraordinary increases in HDL cholesterol levels with vitamin D supplementation. I've touched on the interaction of vitamin D supplementation with HDL in The Heart Scan Blog previously:Vitamin D: Treatment for metabolic syndrome?HDL for DummiesAt first, I thought it was attributable to other factors. In real life, most people don't modify one factor at a time. They reduceprocessed carbohydrates/eliminate wheat and cornstarch, lose weight, add or increase omega-3 fatty acids from fish oil, begin niacin, increase exercise and physical activity. All these efforts also impact on HDL. Among the many things I do, I consult on complex lipid (cholesterol) disorders (complex hyperlipidemias) in my office. A substantial number of these people carry a diagnosis of hypoalphalipoproteinemia, a mouthful that simply means these people are unable to manufacture much apoprotein A1, the principal protein of HDL cholesterol particles. As a result, people with hypoalphalipoproteinemia have HDL cholesterol levels in the neighborhood of 20-30 mg/dl--very low. They are also at high risk for heart disease and stroke. Encourage these people to exercise, attain ideal weight, eliminate wheat and cornstarch: HDL increases 5 mg/dl or so. Add niacin, HDL increases another 5-10 mg/dl. Perhaps we're now sitting somewhere around an HDL of 35-40 mg/dl--better, but hardly great. Add vitamin D to achieve our target serum level . . . HDL jumps to 50, 60, 70, even 90 mg/dl. The first few times this occurred, I thought it was an error or fluke. But now that I've witnessed this effect many dozens of time, I am convinced that it is real. Just today, I saw a 40-year old man whose starting HDL was 25 mg/dl increase to 87 mg/dl. Responses like this are supposed to be impossible. Before vitamin D, I had never witnessed increases of this magnitude. Not all therapies for raising HDL raise the important large (also known as HDL2b) fraction. With lipoprotein analyses, it appears that is principally the large fraction of HDL that rises with vitamin D supplementation. Why? How? That I can't tell you. But for those of you struggling with low HDL cholesterols despite your best efforts, vitamin D can make a world of difference.An interesting corollary: If super-high HDL cholesterols are associated with extreme longevity, as they are with centenarians, does raising HDL to extraordinary levels with vitamin D lead to longer, healthier life, all the way up to age 110 years? Again, no answers, but an interesting thought. And one I'd bet on. (And I'm not selling vitamin D.) << Older posts Newer posts >> Newer posts12...525354555657585960...121122Older posts
Can I see your linea alba? 2. novembre 2010 William Davis (19) As more and more people are eliminating wheat from their diet and losing their "wheat bellies," i.e., the muffin top around their waists along with the visceral fat beneath, I am frequently seeing something I haven't seen in years: the linea alba. Linea alba, or "white line," refers to the band of connective tissue running vertically from sternum to pubic area. It underlies the depression that separates the horizontal abdominal rectus muscles of the "six pack" abdomen. It's like digging in your closet and finding something you thought you'd lost years earlier. Surprise! It's been there all along. Buried deep beneath the abdominal fat from dozens of deep-crust pizzas, whole wheat pasta, and whole grain sandwiches is this pleasing anatomical feature long lost from most peoples' anteriors. Can you see your linea alba?
Dwarf mutant wheat 31. octobre 2010 William Davis (13) Here's my 12-year old standing next to dwarf wheat grown near my house. The wheat is full-grown, harvested about 2 weeks after I took this photo.Wheat is no longer the 4-foot tall "amber waves of grain" of the 20th century. Over 99% of all wheat grown worldwide is now the 18- to 24-inch tall dwarf. New size, new biochemistry, new effects on humans. I call it dwarf "mutant" wheat despite its lack of extra limbs or eyes because of the dramatic transformation required to breed this unique synthetic plant. Short-stature means less stalk, faster growing. The stockier stalk also means that the heavy seed head won't cause the plant to "buckle," as 4-foot tall wheat used to. The thousand-plus proteins of wheat that have been transformed to generate this dwarf mutant also changed wheat's relationship to consuming humans.
Medical education in the days of Big Pharma 30. octobre 2010 William Davis (43) I received this detailed email from an unexpected source: a 3rd-year medical student.In her email, Theresa describes her frustrations in what she is witnessing for the first time, proceeding through her training and getting exposed to the realities of medical life. Medical training, particularly clinical training from the 3rd and 4th years of medical school, onwards through internship, residency, and fellowship training, consists largely of bullying, "pimping" (meaning rapid-fire grilling of questions at trainees), and sleep deprivation. It is an extended hazing period meant to demoralize and inculcate the trainee into following the lead of superiors. Buck the system and you're . . . out. Imagine you've just sunk $190,000 and 8 years of college into getting to your internship. You are not going to chance being thrown out on principle. So you just swallow your pride, go along with the game, and echo all the answers they want you to repeat. While Theresa laments the sad state of modern American pharmaceutical- and procedure-obsessed medicine, she provides me with hope that some young people training to practice medicine today will carve out their own paths, not the one laid for them by the pharmaceutical industry, nor fall for the temptation of higher-paying procedural specialties like orthopedics and cardiology. I am impressed with her ability to see this so early in her career. Dr. Davis,I am a 3rd year medical student at ________ University. I came across your blog today, and I'm very glad I did. I appreciate the value of your time, so I want to be as succinct as possible while still getting across what I'm really thinking and feeling:From what I gathered exploring your blog for a while this afternoon, the wellness strategies you incorporate into your practice are some of the exact things I want to do with my future patients. Personally, I strongly believe in staying healthy by eating right, staying active, etc. For instance, I don't eat grains or much in the way of starches and sugars. So I love the fact that you are helping your patients make these powerful and foundational changes in their lives.As I'm sure was your experience, a full appreciation of nutrition and lifestyle as a first-line health strategy is not something that was taught to me in medical school. I came to school with this deep conviction already in my heart and mind, and now, on my 3rd year rotations, I am still conflicted and at a loss as to how I'm going to be able to practice medicine the way I want to, which is to incorporate these all-important principles into the care of my patients.What I've come to understand about the medical field today is that the information that exists is primarily subsidized by the pharmaceutical industry, and dictated to medical professionals as "evidence-based" treatment guidelines and recommendations by organizations with sincere and official sounding names like American Heart Association and American Cancer Society. Add to that the pressure of potential malpractice litigation and the complexities of the insurance reimbursement game, and it seems to me like what you get is a bunch of diagnostic and medication management algorithms that any half-trained monkey could follow. In his sleep. Which I guess would be alright if at least they weren't algorithms based on misguided, self-serving, profit-seeking Big Pharma, Food Inc, insurance conglomerates, and agri-politics (I think I just made that word up.) A lot of well-intentioned physicians are just parroting the party line, as their patients dutifully and gratefully chomp down their statins and diabetes drugs and blood pressure pills. And I'm sorry, but "diabetes education" programs with curriculum put together by drug companies? How is that even legal? Massive corporations raking in massive profits that are dependent on uncontrolled blood sugars telling people how to best control their blood sugars?!Anyway, forgive my rant. What I'm getting at is this: How can I practice medicine, with the freedom to educate/coach/treat my patients with diet and lifestyle changes to mitigate/reverse their chronic health conditions? Without feeling like I automatically have to first and foremost prescribe the litany of drugs dictated by "evidence-based" guidelines? Without excessive fear of litigation or loss of credibility among my peers? Without having to lie through my teeth to my patients, and tell them that eating low-fat and heart-healthy whole grains is the best way (implication also being the only scientifically proven way) to control their diabetes, lower their cholesterol, etc, etc, etc?I want my patients to have the full benefit of honest nutrition and lifestyle information, and medications and surgery as necessary. I'm afraid that there isn't room for this kind of holistic emphasis in the medical profession today. Are there residencies that include this kind of training or at least respect these "unconventional" philosophies? Are there clinics or practice groups that would allow me to practice with this emphasis, or is there a bias against docs who do not necessarily conform to the party position? Will I have no other option but to go it alone under the auspices of my own shingle? How do you handle these kinds of issues in your professional life?Sincerely,Theresa M. A ray of hope! Perhaps Theresa is just the first among many more medical students who refuse to submit to the brainwashing practices of the pharmaceutical industry, the same mind manipulation that has hopelessly turned most of my colleagues into their unwitting puppets. I'll be interested in watching how Theresa's experience unfolds. I've asked her to keep us informed every so often.
The Great Low-Carb Connector 28. octobre 2010 William Davis (15) The effusive Jimmy Moore of Livin' La Vida Low-Carb asked me to help get the word out about his new podcast subscription service, The Livin' La Vida Low-Carb Show Fan Club.Jimmy has been The Great Connector for the low-carb discussion, from his ubiquitous online and social media presence, to his annual low-carb cruise. He has also broadcast first class interviews of nutritional notables like Gary Taubes, Dr. Robert Lustig, and blogger Stephan Guyenet. His Fan Club expands listener involvement in the podcast process and, potentially, greater access to his guests:My faithful listeners have long been asking me about how they can become even more engaged in the behind-the-scenes workings of the show to get the inside scoop about what’s coming next. I’ve heard people ask specifically for access to transcripts of the most popular podcasts, a listing of the interviews I’m currently working on with the ability to ask questions of those guests, to have sneak peek of audio from not-yet-released interviews and more. My amazing podcast producer, Kevin Kennedy-Spaein, and I have been discussing how to best do this for a while in an effort to meet the demands of our biggest fans and we think we’ve got just the answer for you. Introducing The Livin’ La Vida Low-Carb Show Fan Club!This is for all intents and purposes the quintessential destination for people who can’t get enough of this podcast that goes much deeper than discussion about the low-carb lifestyle. Yes, I speak with a lot of people who are supporters of carbohydrate-restricted diets, but I also talk with fitness gurus, people who support alternative eating plans, those who have interesting theories and beliefs regarding health and much more. Wouldn’t you love to have a chance to know who’s coming up in my schedule to be able to ask them questions BEFORE I interview them? Keep in mind that my interviews are pre-recorded and air sometimes as much as 5-6 months afterwards. Members of the “fan club” would know all about who’s coming and likely will have their question asked on the air just for signing up to be a part of this exciting new addition to “The Livin’ La Vida Low-Carb Show.”Jimmy is the guy who is bringing this disparate and widely-spread community together. He's the guy we all know, he knows "everybody." I'm looking forward to seeing how this new project makes a more involved, personal delivery of interaction possible.
New Track Your Plaque record! 27. octobre 2010 William Davis (19) The record for the largest drop in heart scan score (by percentage of starting score) has been held for around three years, with 63% reduction in score. Well, the longstanding record was broken this week: 75% reduction in score. At the start, Freddie has disastrous lipid values:LDL cholesterol 263 mg/dlHDL 26 mg/dlTriglycerides 323 mg/dlTotal cholesterol 354 mg/dlLipoproteins (NMR) were worse:LDL particle number 3360 nmol/LSmall LDL 2677 nmol/LHeart scan score: 732Interestingly, Freddie had virtually no vitamin D in his body, with a 25-hydroxy vitamin D level that was unmeasurable. Freddie was miserably intolerant to statin drugs, with even the smallest dose resulting in intolerable muscle aches. That's when his doctor sent him to me. Because I felt that the dominant abnormality in Freddie's lipids and lipoproteins was small LDL particles, representing 80% of total LDL particle number, we focused his program on correcting this parameter. Freddie's program was therefore focused elimination of wheat, cornstarch, oats, and sugars, along with an eventual vitamin D dose of 20,000 units to finally achieve a 25-hydroxy vitamin D level of 66 ng/ml. No statin drug in sight. 43 lbs of weight loss and 18 months later, a second heart scan score: 183--a 75% reduction. While the rest of the world continues to insist that coronary calcium (heart scan) scores cannot be reduced, I am seeing records being broken. I add Freddie's experience to the rapidly growing list of people who have not just stopped coronary plaque from growing, but are seizing control and reducing it, sometimes to dramatic degrees.
The Anti-AGEing Diet 22. octobre 2010 William Davis (36) Advanced Glycation End-products, AGEs, are a diverse collection of compounds that have been associated with endothelial dysfunction, cataracts, kidney disease, and atherosclerosis in both animal models and human studies. Not all involve glycation nor glucose, but the catch-all name has stuck. There are a number of actively-held theories of aging, such as the idea that aging is the result of accumulated products of oxidative injury; a genetically pre-programmed script of declining hormones and other phenomena; genetic "mis-reading" that results in disordered gene expression, debris, and uncontrolled cell proliferation (e.g., cancer); among others. One of the fascinating theories of aging is, cutely, the AGEing theory of aging, i.e., the accumulation of AGE debris in various tissues. Such AGEs have been recovered in lenses from the eyes, atherosclerotic plaque in arteries, kidney and liver tissue, even brain tissue of people with Alzheimer's dementia. AGEs perform no known useful physiologic function: They are relatively inert once formed (especially polymeric AGEs), they do not participate in communication, they make no contribution of significance. They simply gum up the works--debris. (AGEs are to health as the USDA food pyramid is to dietary advice: material for the junkyard.)There are two general ways to develop AGEs:1) Endogenous--High blood glucose (any blood sugar above 100 mg/dl) will permit glycation of the various proteins of the body. The higher the blood glucose, the more glycation will proceed. Glycation also occurs at low velocity at blood glucose levels below 100 mg/dl, though this would therefore represent the "normal," expected rate of glycation. Endogenous glycation explains why people with diabetes appear to age and develop all the phenomena of aging faster than non-diabetics (kidney disease, eye diseases, atherosclerosis, dementia, etc.). Hemoglobin A1c, HbA1c, is a readily-obtainable blood test that can show how enthusiastically you have been glycating proteins (hemoglobin, in this case) over the last 2 to 3 months. A low-carbohydrate diet is the nutritional path that limits endogenous glycation leading to AGE formation. Restricting the most obnoxious carbohydrates, the ones that increase blood sugar the most, such as wheat, cornstarch, rice starch, potato starch, tapioca starch, and sucrose, will limit endogenous AGE formation. 2) Exogenous--AGEs (here especially is where the "AGE" label is misleading, since many other reactions besides glycation lead to such compounds) are formed with cooking at high temperatures, especially meats and animal products. Therefore, a rare steak will have far less than a well-done steak. A thoroughly baked piece of salmon will have greater AGE content than sashimi. The forms of cooking that increase AGE content the most: roasting,deep-frying, and barbecuing. Temperatures of 350 degrees Fahrenheit and greater increase AGE formation. Therefore, cooking foods at lower temperature (e.g., baking, sauteeing, or boiling), eating meats rare whenever possible (not chicken or pork, of course), eating raw foods whenever possible (e.g., nuts) are all strategies that limit exogenous AGE exposure. And minimize or avoid butter use, if we are to believe the data that suggest that it contains the highest exogenous AGE content of any known food. If we connect the dots and limit exposure to both endogenous and exogenous AGEs, we will therefore not trigger this collection of debris that is likely associated with disease and aging. So following a low-AGE diet may also be an anti-aging strategy. The New Track Your Plaque Diet, soon to be released on the Track Your Plaque website, has incorporated strategies to limit both endogenous as well as exogenous AGEs.
Butter: Just because it's low-carb doesn't mean it's good 21. octobre 2010 William Davis (59) The diet I advocate in the Track Your Plaque program to gain control over the factors that lead us to coronary plaque and heart attack is a low-carbohydrate diet. We begin with elimination of wheat, cornstarch, oats, and sugars in the context of an overall carbohydrate-reduced diet. We refine the program by monitoring postprandial (after-meal) glucoses. But not everything low-carb is good for you. Fried sausages, for instance, are exceptionally unhealthy, despite having little to no carbohydrates. An emerging but potentially very powerful issue is that of Advanced Glycation End-products, or AGEs. There are two general varieties of AGEs: endogenous (formed within the body) and exogenous (formed in food that is consumed). Endogenous AGEs form in the body as a result of high blood glucose, i.e., glycation. When exposed to any blood glucose level of 100 mg/dl or greater, some measure of glycation will develop due to a reaction between glucose and various proteins, e.g., proteins in the lens of the eye, forming cataracts over time. Exogenous AGEs form in food, generally as a result of heating to high-temperature. (AGEs is really a catch-all term; there are actually a number of reactions that occur in foods, not all of them involving sugars. However, the "AGE" label is used to signify all the various related compounds. The values quoted here are from Dr. Helen Vlassara's Mt. Sinai Hospital laboratory; reference below.) Beef cooked to high-temperature yields plentiful AGEs. One gram of roast beef, for instance, contains 306,238 units. This means that an 8-oz serving yields 13.8 million units AGEs. Compare this to a boiled egg with 573 units per gram, raw tomato with 234 units per gram. Butter contains an impressive 264,873 units AGEs per gram, the highest content per gram in the entire list of 250 foods tested in the Mt. Sinai study. A couple pats of butter (10 g) therefore contains 2.64 million units. A stick of butter that you might add to cake batter to make a cake therefore yields 30 million units of AGEs. So there's nothing wrong with the fat of butter. It's AGEs that appear to be responsible for the endothelial dysfunction/artery-constricting, insulin-blocking, oxidation and inflammation reactions that are triggered. Among all of our food choices, butter is among the worst from this viewpoint. Throw in the peculiar "insulinotrophic" effect of butter, and you have potent distortion of metabolic pathways, courtesy of the butter on your lobster. (AGE data from Goldberg 2004. In this analysis, carboxymethyllysine was the marker used for AGE content.)Incidentally, the new Track Your Plaque diet will soon be released as chapter 9 of the new Track Your Plaque book on the website.
Einkorn now in Whole Foods 16. octobre 2010 William Davis (19) I just saw this at Whole Foods: einkorn pasta. In my einkorn bread experience (In search of wheat: We bake einkorn bread), I was spared the high blood glucose and neurologic and gastrointestinal effects of conventional whole wheat grain (dwarf Triticum aestivum). I shared the einkorn bread with four other people with histories of acute wheat sensitivities, only one of whom experienced a mild diffuse joint reaction, the other three not experiencing any symptoms. Anyone wishing to try einkorn can now obtain commercial pasta from Jovial, an Italy-based manufacturer. It comes in spaghetti, linguine, rigatoni, fusilli, and penne rigate shapes. Eli Rogosa, founder of The Heritage Wheat Conservancy, tells me that, in her experience, celiac suffers seem to not experience immunologic phenomena triggered by conventional wheat. However, we've got to be careful here. The so-called ("diploid") "A" genome of einkorn shares many of the same genes as the ("hexaploid") "ABD" genomes of modern wheat, including overlap in the sequences coding for the 50-or so different glutens and glutenins. Most of the genes that code for the glutens that cause celiac and related illnesses reside in the "D" genome that are absent in the einkorn "A" genome. However, the "A" genome still codes for glutens. So there is potential for activating celiac disease in some people. Insufficient research has been devoted to this question. It is a question of extreme importance to people with celiac and other immune-mediated conditions, since re-exposure to the wrong form of gluten can increase risk of intestinal lymphoma 77-fold, as well as risk of other gastrointestinal cancers. So einkorn should not be viewed as a cure-all for all things wheat, but as something to consider for a carbohydrate indulgence. Yes, indeed: It is a carbohydrate, with 61 grams ("net") carbs per 4 oz (uncooked) serving. Should anyone give it a try, please be sure to report back your experience, especially if you have a history of wheat intolerance. If you have a glucose meter, pre- and 1-hour post values are the ones to measure to gauge the blood sugar effects of consumption. Because pasta tends to cause long sustained blood sugar rises, another value at 2-4 hours might be interesting.
Noodles without the headaches 14. octobre 2010 William Davis (26) If you are looking for a wheat-free noodle or pasta, shirataki noodles are worth a try. Shirataki noodles are low-carbohydrate (less than 3 g per 8 oz package) and, of course, do not trigger all the unhealthy effects of wheat--no blood sugar/insulin provocation, no addictive brain effects (exorphins), no gluten-mediated inflammatory effects. (I advise avoiding gluten-free pasta alternatives made with rice flour and other common gluten alternatives, since they trigger blood sugar, small LDL, and growth of visceral fat just like wheat.)I made a stir-fry using the shirataki-tofu noodles, shown below. (Tofu is added to make the noodles more noodly in consistency, as opposed to the chewier non-tofu variety.) The noodles were a lot like the ramen I used to eat as a kid. They were filling and tasted great in the sesame oil, soy sauce, tofu, and vegetables I used. The noodles are easy to use. Just drain liquid out of package. (The noodles come in water.) Rinse in collander 30 seconds, then boil for 3 minutes. Add to your stir-fry or other dish. Some manufacturers, such as House Foods, also have angel hair and fettucine style noodles.
You're fried 13. octobre 2010 William Davis (26) If I could invent a food that illustrates nearly all of the shortcomings of the American diet, it would be French fries, the familiar fixture of fast food. What we have come to view as French fries contain just about every one of the unhealthy ingredients that lead us down the path of obesity, diabetes, heart disease, high blood pressure, etc. Let's take them one by one:Potato starch--Potato starch exerts an effect on blood sugar similar to that of table sugar, only worse. (Glycemic index french fries 75; glycemic index sucrose 65.) Advanced Glycation End-products (AGEs)--AGEs form when proteins and fats are subjected to high temperature cooking; the longer the high temperature, the more the food reaction creating AGEs proceeds. AGEs are the likely culprit in roasted and fried foods that made it appear that saturated fats were bad, when it was really AGEs all along. AGEs have been shown to block insulin's effects, increase blood sugar, cause endothelial dysfunction and high blood pressure.Acrylamides--Acrylamides, like AGEs, are created through high-temperature heating. French fries are unusually rich in AGEs. Brewed coffee also contains a small quantity, while French fries contain 82-fold greater quantities, among the highest of all known sources of acrylamides.Oxidized oils--The amount of oxidized oils will depend on what sort of oil was used for frying. As more restaurants are trying to get away from hydrogenated oils, many are turning back to polyunsaturates. Others are turning to commercial-grade oils that contain both hydrogenated and polyunsaturates. If oils are permitted to oxidize, then they will trigger oxidative phenomena in your body upon consumptions, e.g., LDL oxidation (Staprans 1994).In other words, the innocent appearing French fry unavoidably triggers oxidation, all the phenomena triggered by high blood glucose (high insulin, glycation, visceral fat accumulation), along with the cascade of effects arising from AGEs and acrylamides.Top your French fries with some ketchup made with high-fructose corn syrup that exagerrates AGE formation, visceral fat, and distorts postprandial (after-eating) effects. Is it any wonder that we've lost control over diet?
Who knows what 4. September 2008 William Davis (4) You know that cynical old saying:It’s not what you know, it’s who you know. In other words, knowing the right person provides you strategic advantage in business, social advancement, etc. In health, it was often true. Knowing who the better doctors were, for instance, in your city might provide you with access to better care. Enter the Information Age. You now have access to medical information equal to that of your doctor. You now have access to patient discussions about doctors, their practices, their performance records. There is now a depth and breadth of information on health that was never available before. I’d therefore turn the old saying into the new Health 2.0 version:It’s not who you know, it’s what you know.In health, information now reigns supreme, not knowing somebody else who has the right connections. Positive: Everybody now theoretically has access to an equal amount of information, since you can access information on any topic just as easily as I can. Negative: It puts more of the burden on you. If you screw up in health, perhaps you didn’t try to get the best information hard enough. I love this new development, this emergence of empowerment in health. I call it self-directed health, the individual capacity to exert enormous influence over the quality of your healthcare. This is obviously a work in progress. All the answers and tools for self-directed care, self-empowerment are not yet available, some haven’t even yet been imagined. But they are coming.
“Too many false positives” 4. September 2008 William Davis (6) “Do you really think I need a heart scan?” asked Terry. “My doctor said that heart scans show too many false positives. He says that many people end up getting unnecessary heart catheterizations because of them.” At age 56, Terry was becoming increasingly frightened. His father had suffered his first heart attack at age 53, Terry’s paternal uncle had a heart attack at age 56, his paternal grandfather a heart attack at age 50. Is this true? Do heart scans yield too many false positives, meaning abnormal results when there really is no abnormality?No, it is not. What Terry’s doctor is referring to is the fact that, in the decades-long process that leads to heart attack, heart scans have the ability to detect early phases of developing coronary atherosclerotic plaque. Let’s take Terry’s case, for example. Given his family history, it is quite likely that he does indeed have coronary atherosclerotic plaque. Will it be detectable by performing a stress test? Probably not. In fact, Terry jogs and feels well while doing so. While a stress test abnormality that fails to reach conscious perception is possible, it’s fairly unlikely given his exercise routine. Will Terry’s coronary atherosclerotic plaque be detectable by heart catheterization? Very likely. But why perform an invasive hospital procedure just as a screening test? Should a woman wishing to undergo a screening test for breast cancer undergo breast removal? Of course not. Is waiting for symptoms a rational way to approach diagnosis of heart disease? Well, when symptoms appear, it means that coronary blood flow is reduced. Stents and bypass surgery may be indicated. The risk of heart attack and death skyrocket. Sudden death becomes a real possibility. In the 30 or so years required to establish sufficient coronary plaque to permit the appearance of symptoms or the development of an abnormality detectable by stress testing, there were many years when the disease was early--too early to generate symptoms, too early to be detectable by stress testing. That’s when heart scans uncover evidence for silent coronary atherosclerotic plaque.Should we call this a “false positive” just because it doesn’t also correlate with “need” for a catheterization, stent, bypass operation or result in heart attack within the next few weeks? The detection of early plaque is just that: early disease detection. Imagine, for instance, that the breast cancer that will grow into a palpable nodule or mass detectable by mammogram is detectable by a special breast scan 15 years before it becomes a full-blown tumor, metastasizing to other organs. What if effective means to halt that earliest evidence of cancer could put a stop to this devastating disease decades ahead of danger? Is this a “false positive” too?In my view, this is the knuckleheaded thinking of the conventional practitioner: “Don’t bother me until you’re really sick.” Prevention is a practice that has become fashionable only because of the push of the drug industry. Nutrition is an afterthought, a message conceived through consensus of “experts” with suspect motivations and allegiances. So, no, heart scans do not uncover “false positives.” They uncover early disease--true positives--years before it is detectable by standard tests or by the appearance of catastrophe. But that is the whole point: Early detection means getting a head start on prevention.Do heart scans lead to unnecessary heart catheterizations? Yes, sadly they do. But not because heart scans are false positive. It happens because of unscrupulous or ignorant cardiologists who use the information wrongly. In my view, heart scans should NEVER lead directly to heart catheterization in an asymptomatic patient. Heart scans, as helpful as they are, do not modify the standard reasons for performing heart procedures. If a car mechanic is dishonest and fixes a carburetor that didn't need fixing, should we condemn all car mechanics? No, of course not. We only need to develop the means to weed out the bad apples. The same applies to heart scans.
Triglycerides divided by five 3. September 2008 William Davis (8) Here's a bit of lipid tedium that might nonetheless help you one day decipher the meaning of shifts in your cholesterol panel. Recall from prior discussions that conventional LDL cholesterol is a calculated value. Contrary to popular opinion, LDL is usually not measured, but calculated from the Friedewald equation:LDL cholesterol = Total cholesterol - HDL cholesterol - triglycerides/5For the sake of simplicity, let's call total cholesterol TC; HDL cholesterol HDL, and triglycerides TG. We've also talked in past how a low HDL makes calculated LDL inaccurate, sometimes wildly so. (See Low HDL makes Dr. Friedewald a liar.)Here's yet another source of inaccuracy of the Friedewald-calculated LDL: any increase in triglycerides.Let's say, for instance, that starting lipid panel shows:TC 170 mg/dlLDL 100 mg/dl HDL 50 mg/dlTG 100 mg/dlYou're advised to follow a standard low-fat, whole grain-rich diet advocated by "official" agencies (the diet I bash as knuckleheaded). Another panel a few months later shows:TC 230 mg/dlLDL 140 mg/dlHDL 50 mg/dlTG 200 mg/dl(Obviously, I've oversimplified the response for the sake of argument. HDL would likely go down, LDL would change more depending on body weight, small LDL tendencies, and other factors. You'd also likely get fat.) Now your doctor declares that your LDL has gone up and you "need" a statin agent. Nonsense, absolute nonsense. What has really happened is that the increased dietary intake of wheat and other "healthy whole-grain foods" has caused triglycerides to skyrocket. LDL increases, in turn, by a factor of TG/5, or 40 mg/dl. Thus, LDL has been inflated by the triglyceride-raising effect of whole grains. This is yet another reason why the standard lipid panel, full of hazards and landmines, needs to be abandoned. But calculated LDL in particular is an exercise in frustration. Though the example used is hypothetical, I've witnessed this effect thousands of times. I've also seen many people placed on statin drugs unnecessarily, due to the appearance of a high LDL cholesterol that really represented increased TG/5, usually induced by an excessive carbohydrate intake, including those commonly misrepresented as healthy such as whole grains.
Who reads The Heart Scan Blog? 2. September 2008 William Davis (0) In the Heart Scan Blog, I am often guilty of speaking out loud of my varied thoughts on this crazy thing that we've created called the cardiovascular healthcare machine. But I discuss it in the context of asking "How could this be done better--better outcomes, more patient-friendly, more accessible . . . more do-it-yourself? The last part is the part that throws most people. Do-it-yourself? My colleagues would claim I'm nuts, suggesting that coronary heart disease is something manageable by yourself. In the conventional pathway, after all, coronary disease is that unpredictable, poorly detected by standard tests, condition that then leads to heart catheterization, stents, bypass , and the like. Several factors distinguish the readers of The Heart Scan Blog that surprised me:--Nearly 60% are women--There are a disproportionate number of Asian people. (Can someone explain this to me?) --A great number have graduate degreesI believe this tells me that The Heart Scan Blog appeals to a somewhat more sophisticated audience. This, to some degree, warms my heart, since it means that I've captured the attention of some people who may be more discriminating and thoughtful in their Internet surfing. However, I also lament the fact that these conversations are not achieving the mainstream. After all,
Kitchen sink approach for Lp(a) 29. August 2008 William Davis (12) Lipoprotein(a), Lp(a), can be a tough nut to crack. Having struggled and wrestled with this genetic pattern for the last 12 years or so in hundreds of patients, I have gained great respect for this difficult to control pattern. I regard lipoprotein(a) as the number one most aggressive cause for heart disease and coronary plaque known. It can account for heart attacks in men in their 40s, women in their 50s. It can cause heart disease and heart attacks in even the ultra-fit like marathon runners. It accounts for both excessive coronary risk and misleading cholesterol values in slender, healthy-appearing people. Niacin is the number one treatment choice for Lp(a), followed by testosterone for men, estrogens (preferably human, not horse or other non-human mammal) for women. I then often resort to DHEA, along with adjunctive nutritional agents like raw almonds, ground flaxseed, and others. Our most recent addition to the Lp(a) treatment list is high-dose fish oil, which appears to exert a significant effect in about 40% of people with Lp(a). Even with this multi-agent approach, not everybody gains control over Lp(a).That makes me wonder if someone has Lp(a) at a substantial level of, say, 200 nmol/L or 70 mg/dl (values can differ tremendously, depending on the method of measurement), should we throw everything but the kitchen sink at Lp(a) from the start? Right now, by adding an agent one at a time, it often takes two years to gain control over Lp(a) (if we are going to get it at all).While many people might find this unpalatable and overwhelming from the starting gate of their program, I do believe it may be a strategy we should consider adopting for full and more immediate plaque control in the Track Your Plaque program. Something to chew on. Clearly, we need better answers for Lp(a). A "kitchen sink," full-frontal assault might be a way to gain faster control, though not necessarily a superior approach with regards to efficacy and potency. There are a number of unique, potentially effective therapies for Lp(a) that are worth examining. Given the difficulty of performing clinical trials with non-drug agents (largely a lack of financial support, since nobody gets a financial return with non-patent-protectable agents), I am anxious to put these potential treatments to a test in the Track Your Plaque program Virtual Clinical Trail (VCT). The VCT gives us a quick and relatively easy method to test various potential treatments, with feedback generated in months, rather than years. Any suggestions on promising agents to test? Of course, they must be widely available nutritional agents, not drugs.
Making Dr. Friedewald an honest man 28. August 2008 William Davis (3) Colleen started with the usual discrepancy between conventional calculated LDL cholesterol of 121 mg/dl and the far more accurate LDL particle number (NMR) of 1927 nmol/L. Those of you following this conversation or our many conversations on the Track Your Plaque Forum know that a useful and highly reliable rule-of-thumb for converting NMR LDL particle number to LDL is to drop the last digit: 1927 nmol/L becomes 192 mg/dl. (This is, admitttedly, arrived at empirically, not by design. However, it has held up through thousands of NMR analyses and plays out reasonably when you compare distributions of Friedewald LDL and LDL particle number on a population basis.)In other words, by this simple manipulation, Colleen's Friedewald calculated LDL is off by 58%. This is very common, a phenomenon I witness several times every day. By LDL particle size, 75% of all Colleen's LDL particle were abnormally small (small LDL particle number 1440 nmol/L). This is a moderately severe small LDL tendency.So we took all the steps for reduction of small LDL/LDL, including elimination of wheat and cornstarch, exercise, weight loss (which happens inevitably when wheat and cornstarch are eliminated), fish oil, vitamin D, etc. Another NMR lipoprotein panel showed an LDL particle number of 882 nmol/L and a Friedewald calculated LDL of 87 mg/dl. Using our rule-of-thumb, LDL by particle number is virtually the same as the calculated LDL. This time, small LDL numbered only 237 nmol/L, or 26.8% of the total, a marked reduction. Isn't that interesting? As small LDL is corrected, the crude Friedwald calculated LDL approximates the more accurate LDL particle number. It assumes that accuracy of the Friedewald calculation may be more likely to occur as LDL size approaches normal. However, when LDL size is abnormally small--a condition shared by at least 70% of people with coronary heart disease--then the Friedewald LDL becomes increasingly inaccurate.The opposite can also happen: When all or nearly all LDL particles are large, Friedewald calculated LDL can markedly overestimate LDL particle number. Yesterday, for instance, a patient had a Friedewald calculated LDL of 183 mg/dl, but an NMR particle number of 1110 nmol/L--drop the zero . . . LDL 110 mg/dl. This woman was advised to take a statin drug by her primary care physician, based on the Friedewald LDL. Instead, she proved to have a far lower LDL. She would not have benefitted from taking a statin drug. As I've warned many times before: Beware the Friedewald calculated LDL.
Some basic vitamin D issues 24. August 2008 William Davis (7) The last post on vitamin D raised a number of basic questions among readers. So let me discuss some of these questions one by one. All of them raise important issues surrounding the practical aspects of managing vitamin D in your health. Anne said:I think it is important to stress that vitamin D supplementation needs to be continued long term. I have met too many people who have been prescribed 50,000 IU of D2 for 8-12 weeks and then told to stop because their 23(OH)D went over 30ng/ml. I know one person who's doctor stopped and started the D2 3 times. Thanks for pointing that out, Anne. Excellent point. I also see doctors do this with statin drugs: start it, check a LDL level which is lower, then think that you're done and stop the drug. What the heck are they thinking? If vitamin D is not being produced by sun exposure and not obtainable through diet, continued supplementation is necessary, essentially for life. Twinb asked:How often you think Vit. D levels should be tested after the initial test is done, especially if the levels are drastically low?We have used every 6 months in the office. Ideally, levels are in mid-summer and mid- to-late winter in order to gauge the extremes of your seasonal fluctuations. While most adults over 40 fail to fluctuate more than 10 ng/ml in the Wisconsin climate (and this summer, after an initial rainy season early, has been flawlessly bright and sunny, in the high-70s and 80s every single day for months), an occasional person fluctuates more widely. The only way to judge is to check a blood level. Rich said:Vitamin D dosage effects appear to be quite idiosyncratic.Yes, indeed it is. Despite using crude rules-of-thumb, like taking 1000 units of vitamin D per 10 ng/ml desired (a rule I learned from Dr. John Cannell, which he offered fully aware of its inaccuracy), many people will surprise you and have levels that make no sense. Testing is crucial to know your vitamin D level. Richard asked: Where do we get enough vitamin D wihout worring about laboratory tests? Well, the entire point of the post was that you absolutely, positively cannot just take vitamin D blindly at any dose and hope that your level is ideal, no more than you can blindly take a dose of thyroid and know you have achieved normal thyroid levels. In my view, vitamin D blood levels are an absolute. Another simple issue: Don't be afraid of vitamin D. It is, in all practicality, no more dangerous than getting a dark tan. (But, as many of you realize, getting a tan is no assurance of raising vitamin D if you are over 40 years old.)Wouldn't it be great if someone developed a do-it-yourself-at-home skin test for vitamin D? I know of no effort to develop this, but it would be a huge advantage for all of us.
“How much vitamin D should I take?” 22. August 2008 William Davis (17) It’s probably the number one most common question I get today: “How much vitamin D should I take?”Like asking for investing advice, there are no shortage of people willing to provide answers, most of them plain wrong. The media are quick to offer advice like “Take the recommended daily allowance of 400 units per day,” or “Some experts say that intake of vitamin D should be higher, as high as 2000 units per day.” Or “Be sure to get your 15 minutes of midday sun.”Utter nonsense. The Food and Nutrition Board of the Institute of Medicine has been struggling with this question, also. They have an impossible job: Draft broad pronouncements on requirements for various nutrients by recommending Recommended Daily Allowances (RDA) for all Americans. The Food and Nutrition Board has tried to factor in individual variation by breaking vitamin D requirements down by age and sex, but what amounts to a one-size-fits-nearly-all approach. Much of the uncertainty over dosing stems from the fact that vitamin D should not be called a “vitamin.” Vitamins are nutrients obtained from foods. But, outside of oily fish, you'll find very little naturally-occurring vitamin D in food. (Even in fish, there is generally no more than 400 units per 4 oz. serving.) Sure, there’s 20 units in an egg yolk and you can activate the vitamin D in a shiitake mushroom by exposing it to ultraviolet radiation. Dairy products like milk (usually) contain vitamin D because the USDA mandates it. But food sources hardly help at all unless you’re an infant or small child. It all makes sense when vitamin D is viewed as a hormone, a steroid hormone, not a vitamin. Vitamin-no, steroid hormone-D exerts potent effects in tiny quantities with hormone-like action in cells, including activation of nuclear receptors. It is the only hormone that is meant to be activated by sun exposure of the skin, not obtained through diet. But the ability to activate D is lost by the majority of us by age 40 and even a dark tan is no assurance that sufficient skin prohormone D activation has taken place. As with any other hormone, such as thyroid, parathyroid, or growth hormones, dose needs to be individualized. Imagine you developed a severely low thyroid condition that resulted in 30 lbs of weight gain, lose your hair, legs swell, and heart disease explodes. Would you accept that you should take the same dose of thyroid hormone as every other man or woman your age, regardless of your body size, proportion of body fat, metabolism, genetics, race, dietary habits, and other factors that influence thyroid hormone levels? Of course you wouldn’t. Then why would anyone insist that vitamin D be applied in a one-size-fits-all fashion? (There’s another world in which a one-size-fits-all approach to hormone replacement has been widely applied, that of female estrogen replacement. In conventional practice, there’s no effort to identify need, estrogen-progesterone interactions, nor assess the adequacy of dose, not to mention the perverse non-human preparation used.) With thyroid hormone, ideal replacement dose of hormone ranges widely from one person to another. Some people require 25 mcg per day of T4; others require 800% greater doses. Many require T3, but not everybody. Likewise, vitamin D requirements can range widely. I have used anywhere from 1000 units per day, all the way up to 16,000 units per day before desirable blood levels were achieved. Vitamin D dose needs to be individualized. Factors that influence vitamin D need include body size and percent body fat (both of which increase need substantially); sex (males require, on average, 1000 units per day more than females); age (older need more); skin color (darker-skinned races require more, fairer-skinned races less); and other factors that remain ill-defined. But these are “rules” often broken. My office experience with vitamin D now numbers nearly 1000 patients. The average female dose is 4000-5000 units per day, average male dose 6000 units per day to achieve a blood level of 60-70 ng/ml, though there are frequent exceptions. I’ve had 98 lb women who require 12,000 units, 300 lb men who require 1000 units, 21-year olds who require 10,000 units. (Of course, this is a Wisconsin experience. However, regional differences in dosing needs diminish as we age, since less and less vitamin D activation occurs.)Let me reiterate: Steroid hormone-vitamin D dose needs to be individualized. There’s only one way to individualize your need for vitamin D and thereby determine your dose: Measure a blood level. Nobody can gauge your vitamin D need by looking at you, by your skin color, size, or other simple measurement like weight or body fat. A vitamin D blood level needs to be measured specifically-period. Unfortunately, many people balk at this, claiming either that it’s too much bother or that their doctor refused to measure it. I would rank normalizing steroid hormone-vitamin D as among the most important things you can do for your health. It should never be too much bother. And if your doctor refuses to at least discuss why he/she won’t measure it, then it’s time for a new doctor. If you’re worried about adding to rising healthcare costs by adding yet another blood test, think of the money saved by sparing you from a future of cancer, heart disease, osteoporosis, diabetes, etc. The cost of a vitamin D blood test is relatively trivial (around $40-50, a fraction of the cost of a one month supply of a drug for diabetes.) So how much vitamin D should you take? Enough to raise your blood level of 25-hydroxy vitamin D to normal. (We aim for a normal level of 60-70 ng/ml.)
You probably don't take enough fish oil 20. August 2008 William Davis (17) The results of the recent Heart Scan Blog survey in response to the question: MY DAILY DOSE OF EPA + DHA FROM FISH OIL IS revealed:Zero--I don't take any 17 (7%) of respondents Less than 1000 mg per day 24 (10%) of respondents 1000-2000 mg per day 91 (38%) of respondents 2000-3000 mg per day 44 (18%) of respondents 3000-4000 mg per day 40 (16%) of respondents More than 4000 mg per day 20 (8%) of respondentsBased on the above results, I would say that only a minority of respondents are taking an ideal dose of omega-3 fatty acids. Nearly all of us should consider taking more. Benefits of omega-3 fatty acids (EPA + DHA) from fish oil begin around a dose of 840 mg per day, according to the GISSI Prevenzione Trial of 1999, an 11,000-participant trial. This dose also corresponds to a quantity of omega-3s that have been shown to raise EPA + DHA blood levels and thereby reduce the notoriously high AA:EPA ratio of Americans. But what dose is sufficient? What dose is ideal? Well, the answer to a great degree depends on what you are taking the fish oil for. If being taken to reduce triglycerides and triglyceride-containing lipoproteins, like VLDL and the after-eating (postprandial) IDL, then a higher dose will be necessary. (Triglyceride reduction for the genetically-determined very high triglyceride level of familial hypertriglyceridemia is the FDA-approved indication for prescription Lovaza.) If you are taking fish oil for treatment of ADHD, depression, or bipolar illness, very high doses are often necessary. But how about maximal reduction of cardiovascular risk and for control or reversal of atherosclerotic plaque? This conversation is still evolving. But we can learn some important lessons from three populations of the world that are vigorous consumers of fish:--The Inuits (aka Eskimos) of Greenland and northern Canada--The Japanese--The Bantus of Tanzania who live along Nyasa LakeAll three indigenous populations have several-fold greater intakes of fish and omega-3 fatty acids, have higher blood levels of omega-3 fatty acids, and have enjoyed reduced cardiovascular events, reduced atherosclerotic plaque, or improvement in various surrogates of cardiovascular risk (e.g., Lp(a)). The most recent addition to this conversation is the ERA JUMP Study, discussed in a previous Heart Scan Blog post. In ERA JUMP, despite being heavy smokers and having other markers for greater risk for heart disease, Japanese men living in Japan had markedly less carotid and coronary plaque, as compared to Caucasian men living in PIttsburgh or Hawaiian men of Japanese descent. The difference appeared to be attributable to serum levels of omega-3 fatty acids. I believe that the trend is here is to increase the amount of omega-3 fatty acids that most of us take. In the Track Your Plaque program, we have been advocating a rock-bottom starting dose of EPA + DHA of 1200 mg per day. However, I believe that this is due for a change. We will be increasing the minimum dose for plaque regression and control. Please attend our Webinar this evening for a full, in-depth discussion of the rationale behind this important change. As always, let me remind you that I am not selling, nor ever have sold, fish oil supplements. If I advocate a specific dose, a higher dose, I do so based on my interpretation of the data and experience with patients, not because I am interested in selling brand X of fish oil.
Vitamin D and HDL 19. August 2008 William Davis (23) Despite the paucity of scientific documentation of this phenomenon, I am continuing to witness extraordinary increases in HDL cholesterol levels with vitamin D supplementation. I've touched on the interaction of vitamin D supplementation with HDL in The Heart Scan Blog previously:Vitamin D: Treatment for metabolic syndrome?HDL for DummiesAt first, I thought it was attributable to other factors. In real life, most people don't modify one factor at a time. They reduceprocessed carbohydrates/eliminate wheat and cornstarch, lose weight, add or increase omega-3 fatty acids from fish oil, begin niacin, increase exercise and physical activity. All these efforts also impact on HDL. Among the many things I do, I consult on complex lipid (cholesterol) disorders (complex hyperlipidemias) in my office. A substantial number of these people carry a diagnosis of hypoalphalipoproteinemia, a mouthful that simply means these people are unable to manufacture much apoprotein A1, the principal protein of HDL cholesterol particles. As a result, people with hypoalphalipoproteinemia have HDL cholesterol levels in the neighborhood of 20-30 mg/dl--very low. They are also at high risk for heart disease and stroke. Encourage these people to exercise, attain ideal weight, eliminate wheat and cornstarch: HDL increases 5 mg/dl or so. Add niacin, HDL increases another 5-10 mg/dl. Perhaps we're now sitting somewhere around an HDL of 35-40 mg/dl--better, but hardly great. Add vitamin D to achieve our target serum level . . . HDL jumps to 50, 60, 70, even 90 mg/dl. The first few times this occurred, I thought it was an error or fluke. But now that I've witnessed this effect many dozens of time, I am convinced that it is real. Just today, I saw a 40-year old man whose starting HDL was 25 mg/dl increase to 87 mg/dl. Responses like this are supposed to be impossible. Before vitamin D, I had never witnessed increases of this magnitude. Not all therapies for raising HDL raise the important large (also known as HDL2b) fraction. With lipoprotein analyses, it appears that is principally the large fraction of HDL that rises with vitamin D supplementation. Why? How? That I can't tell you. But for those of you struggling with low HDL cholesterols despite your best efforts, vitamin D can make a world of difference.An interesting corollary: If super-high HDL cholesterols are associated with extreme longevity, as they are with centenarians, does raising HDL to extraordinary levels with vitamin D lead to longer, healthier life, all the way up to age 110 years? Again, no answers, but an interesting thought. And one I'd bet on. (And I'm not selling vitamin D.)
