Genetic vs. lifestyle small LDL 19. February 2010 William Davis (59) Let me explain what I mean by "genetic small LDL." I think it helps to illustrate with two common examples. Ollie is 50 years old, 5 ft 10 inches tall, and weighs 253 lbs. BMI = 36.4 (obese). Starting lipoproteins (NMR):LDL particle number 2310 nmol/LSmall LDL: 1893 nmol/L (1893/2310 = 81.9% of total, a severe small LDL pattern)Stan is 50 years old, also, 5 ft 10 inches tall, and weighs 148 lbs. BMI = 21.3. Starting lipoproteins:LDL particle number 1424 nmol/LSmall LDL 1288 nmol/L (1288/1424 = 90.4% of total, also severe)Both Ollie and Stan go on the New Track Your Plaque diet and eliminate wheat, cornstarch, and sugars, while increasing oils, meats and fish, unlimited raw nuts, and vegetables. They add fish oil and vitamin D and achieve perfect levels of both. Six months later, Ollie has lost 55 lbs, Stan has lost 4 lbs. A second round of lipoproteins:Ollie:LDL particle number 1810 nmol/LSmall LDL: 193 nmol/L (193/1810 = 10.6% of total)Stan:LDL particle number 1113 nmol/LSmall LDL 729 nmool/L (729/1113 = 65.4% of total)Ollie has reduced, nearly eliminated, small LDL through elimination of wheat, cornstarch, and sugars, along with weight loss, fish oil, and vitamin D. Stan, beginning at a much more favorable weight, reduced both total and small LDL with the same efforts, but retains a substantial proportion (65.4%) of small LDL. Stan's pattern is what I call "genetic small LDL." Of course, this is a presumptive designation, since we've not identified the specific gene(s) that allow this (e.g., gene for variants of cholesteryl ester transfer protein, hepatic lipase, lipoprotein lipase, and others). But it is such a sharp distinction that I am convinced that people like Stan have this persistent pattern as a genetically-determined trait.
Carbohydrate sins of the past 17. February 2010 Toggle navigation Home Blog Home Archive Join Now Log in Man walks after removing wheat 9. May 2010 William Davis (27) No, this isn't some National Enquirer headline like "Woman delivers alien baby."Tom is a 26-year old man with a complex medical condition, a malformation he was born with and has had reconstructed. Aside from this, he leads a normal life: works, is married, and is, in fact, quite intelligent. He came to me for an opinion regarding his overall health. Tom was worried that his congenital condition would impair his long-term health and longevity prospects, so he wanted to optimize all other aspects of his health.But, when I examined Tom, he could barely get himself up on the exam table without wincing in pain. When I asked him to walk, he hobbled a few steps, again clearly in pain. When I asked him what hurt, he said "everything." He said that all his joints hurt just to move. He told me that his several doctors over the years didn't know why he was in such pain: It wasn't rheumatoid arthritis, gout, pseudogout, or any of the other inflammatory joint diseases that might account for virtually incapacitating this 26-year old man. Even the rheumatologists were stumped. It was also unrelated to his repaired congenital condition. So Tom went on with his life, barely able to even go for a walk with his wife without pain, slowing him down to the pace of an 80-year old. So I suggested that he eliminate all wheat products. "I don't know for a fact whether it will work, Tom. But the only way to find out is to give it a try. Why not try a 4-week period of meticulously avoiding wheat? Nothing bad will come of it."He and his wife look perplexed, but were so desperate for a solution that they agreed to give it a try. Tom returned 6 weeks later. He walked into the room briskly, then bounded up on the exam table. He told me that, within days, all his joint pains had completely disappeared. He could walk, stretch, do all the normal physical things with none of the pain he had suffered previously. Tom told me, "I didn't think it could be true. I thought it was just a coincidence. So I had a sandwich about 2 weeks into it. In about 5 minutes, I got about half my pains back."Tom now remains wheat-free and pain-free, thankfully with no discernible joint impairment. So, yes, Tom walked freely and without pain simply by eliminating wheat from his life. Is it an immune phenomenon? Does wheat gluten trigger some inflammatory reaction in some people? There is surely something like this underlying experiences like Tom. Wheat contains far more than gluten. Modern wheat is a collection of hundreds of different proteins, though gluten is the most plentiful, the one that confers the "viscoelasticity" of dough. But there's plenty more to wheat than gluten or celiac disease. AGEing gracefully 5. May 2010 William Davis (32) Advanced Glycation End-products, or AGEs, have the potential to change our entire conversation about diet. AGEs come from two principal sources: 1) Endogenous--Glucose-protein interactions that arise from high blood glucose levels 2) Exogenous--From diet The first is sensitive to glucose levels: the higher the glucose level, the greater the AGE formation. The second depends on the quantity of AGE in the food consumed.A compelling body of evidence points towards AGEs as an agent of aging, as well as kidney dysfunction, dementia, and atherosclerosis. Some of the observations made include:--If AGEs are infused into an experimental animal, it develops atherosclerosis, kidney disease, and other "diseases of senescence" within weeks to months. --In endothelial cells (cells lining arteries), AGE induces expression of adhesion molecules and inflammatory signals. In fibroblasts, AGE provokes collagen production. In smooth muscle cells, AGE triggers migration and proliferation. In monocytes and macrophages, AGEs induce chemotaxis and release of inflammation mediators. In short, AGEs have been implicated in just about every step leading to atherosclerosis.--In humans, greater quantities of AGEs are present in diabetics, pre-diabetics and people with insulin resistance. We all know that these people develop atherosclerosis, kidney disease, cataracts, and other conditions at an accelerated rate. --Foods containing greater quantities of AGEs cause endothelial dysfunction, i.e., artery constriction via blockade of nitric oxide and other mechanisms.Short of taking agents that block AGE activity, how can you minimize the absorption or production of AGEs? There are two general strategies:1) Keep blood glucose low--The Whitehall study demonstrated increased cardiovascular mortality with a postprandial (actually 2-hour post- 50-gram glucose challenge) blood sugar of 83 mg/dl. Lower blood glucose, less glycation. Less carbohydrates in the diet, the lower the blood sugar, the less the glycation. Studies like Whitehall demonstrate that glycation begins with glucose values within the normal range. Thus, aging occurs even with normal glucose levels. It occurs faster with higher glucose levels. 2) Choose and prepare foods with lower AGE content. Food content of AGEs is a major determinant of blood AGE levels. Fats and meats are the primary dietary source of AGEs, particularly if cooked at high temperature (broiling, frying). While this does not mean that meats and fats need to be avoided, it can mean that limiting serving size of meats and fats, while being selective in how they are prepared, are important. This can mean cutting your meats in thinner slices or smaller pieces to permit faster cooking, eating rare when possible (not poultry, of course), avoiding cooking with sauces that contain sugar (which enhances AGE formation). Is this an argument in favor of sashimi?Minimizing exposure to AGEs, endogenous or exogenous, has the potential to slow the aging process, or at least to lessen the likelihood of many of the phenomena of aging. More on this to come. Small LDL: Simple vs. complex carbohydrates 4. May 2010 William Davis (17) Joseph is a whip-smart corporate attorney, but one who accepts advice at his own pace. He likes to explore and consider each step of the advice I give him. Starting (NMR) lipoprotein panel on no treatment or diet change:LDL particle number 2620 nmol/L (which I would equate to 262 mg/dl LDL cholesterol) Small LDL 2331 nmol/L--representing 89% of LDL particle number, a severe dominance of small LDLI advised him to eliminate wheat, cornstarch, and sugars, while limiting other carbohydrate sources, as well. Joseph didn't like this idea very much, concerned that it would be impractical, given his busy schedule. He also did a lot of reading of the sort that suggested that replacing white flour with whole grains provided health advantages. So that's what he did: Replaced all sugar and refined flour products with whole grains, but did not restrict his intake of grains. Next lipoprotein panel with whole grains replacing white refined flour:LDL particle number 2451 nmol/L Small LDL 1998 nmol/L--representing 81.5% of LDL particle number. In other words, replacing white flour products with whole grain products reduced small LDL by 14%--a modest improvement, but hardly great. I explained to Joseph that any grain, complex, refined, or simple--will, just like other sugars and carbohydrates, still provoke small LDL. Given the severity of his patterns, I suggested trying again, this time with full elimination of grains. Next lipoprotein panel with elimination of whole grains:LDL particle number 1320 nmol/LSmall LDL 646 nmol/L--48.9% of total LDL particle number, but a much lower absolute number, a reduction of 67.6%. This is typical of the LDL responses I see with elimination of wheat products on the background of an overall carbohydrate restriction: Big drops in precisely measured LDL as LDL particle number (i.e., an actual count of LDL particles, not LDL cholesterol) and big drops in the number of small LDL particles. You might say that wheat elimination and limitation of carbohydrate intake can yield statin-like values . . . without the statin. Is Cocoa Puffs no longer heart healthy? 29. April 2010 William Davis (17) Until recently, Cocoa Puffs enjoyed the endorsement of the American Heart Association (AHA) as a heart-healthy food. For a price, the AHA will allow food manufacturers to affix a heart "check mark" signifying endorsement by the AHA as conforming to some basic "heart healthy" requirements. Odd thing: The list of breakfast cereals on the check mark program has shrunk dramatically. When I last posted about this, there were around 50-some breakfast cereals, from Cocoa Puffs to Frosted Mini Wheats. Now, the list has been trimmed down to 17:Berry Burst Cheerios-Triple BerryCheeriosCheerios CrunchHoney Nut CheeriosKashi Heart to Heart Honey Toasted Oat CerealKashi Heart to Heart Oat Flakes & Wild Blueberry ClustersKashi Heart to Heart Warm Cinnamon Oat CerealMulti Grain CheeriosOatmeal Crisp Crunchy AlmondOatmeal Crisp Hearty RaisinQuaker Cinnamon LifeQuaker Heart HealthQuaker LifeQuaker Life Maple & Brown SugarQuaker Oat BranQuaker Oatmeal Squares - Brown SugarQuaker Oatmeal Squares - Cinnamon According to sales material targeted to food manufacturers, the American Heart Association boasts that "The American Heart Association’s heart-check mark is the most recognized and trusted food icon today . . . Eighty-three percent of consumers are aware of the heart-check mark. Sixty-six percent of primary grocery shoppers say the heart-check mark has a strong/moderate influence on their choices when shopping."So, is Cocoa Puffs no longer heart healthy? I suspect that agencies like the AHA, the USDA, the American Diabetes Association as starting to understand that they have blundered big time by pushing low-fat, having contributed to the nationwide epidemic of obesity and diabetes, and that it is time to quietly start backpedaling. While it's a step in the right direction, judging from the above list of breakfast cereal "survivors" of the check mark program, the criteria may have been tightened . . . but not that much. Fractures and vitamin D 27. April 2010 William Davis (25) This is a bit off topic, but it's such an interesting observation that I'd like to pass it on. Over the past several years, there have been inevitable bone fractures: People slip on ice, for instance, and fracture a wrist or elbow. Or miss a step and fracture a foot, fall off a ladder and fracture a leg. People will come to my office and tell me that their orthopedist commented that they healed faster than usual, often faster than anyone else they've seen before. My son was told this after he shattered his hand getting slammed against the boards in hockey; his orthopedist took the screws and cast off much sooner than usual since he judged that healing had occured early. (My son was taking 8000 units vitamin D in gelcap form; I also had him take 20,000 units for several days early after his injury to be absolutely sure he had sufficient levels.)My suspicion is that people taking vitamin D sufficient to enjoy desirable blood levels (I aim for a 25-hydroxy vitamin D level of 60-70 ng/ml) heal fractures much faster, abbreviating healing time (crudely estimated) by at least 30%.For any interested orthopedist, it would be an easy clinical study: Enroll people with traumatic fractures, randomize to vitamin D at, say, 10,000 units per day vs. placebo, watch who heals faster gauged by, for instance, x-ray. My prediction: Vitamin D will win hands down with faster healing and perhaps more assured fusion of the fracture site. T3 for accelerating weight loss 25. April 2010 William Davis (57) Supplementation of the thyroid hormone, T3, is an underappreciated means to lose weight. Thyroid health, in general, is extremely important for weight control, since even subtle low thyroid hormone levels can result in weight gain. The first step in achieving thyroid health is to be sure you are obtaining sufficient iodine. (See Iodine deficiency is real and Healthy people are the most iodine deficient) But, after iodine replacement has been undertaken, the next step is to consider your T3 status. I've seen T3 ignite weight loss or boost someone out of a weight loss "plateau" many times. Endocrinologists cringe at this notion of using T3. They claim that you will develop atrial fibrillation (an abnormal heart rhythm) and osteoporosis by doing this. I have yet to see this happen. Adding T3 revs up metabolic rate at low doses. The idea is to push free T3 hormone levels to the upper limit of normal, but not to the hyperthyroid range. While an occasional person feels a little "hyper" like they've had a pot of coffee, most people just feel energized, clear-headed, and happier. And weight trends down much more readily. Taking T3 by itself with no effort at weight loss generally yields only a modest weight reduction. However, T3 added to other weight reducing efforts, such as wheat elimination and exercise, accelerates the weight loss effect considerably. 5 lbs lost will likely be more like 8 to 10 lbs lost; 10 lbs lost will likely be more like 15 to 20 lbs, etc.It's also my suspicion that more and more people are developing a selective impairment of T3, making it all the more important. I believe that you and I are being exposed to something (perchlorates, bis 410mg, DHA 274.Thanks for your blog. It made me feel better that I wasn't the only one outraged by this stuff. I 've been a nurse for 20 years and it just never seems to get better. Thank you for your wisdom. Sincerely JP, TennesseeHad this reader not been aware that her brother could take fish oil as a nutritional supplement, he likely would have been denied the benefit of omega-3 fatty acids in slashing the risk for recurrent cardiovascular events. You and I can buy wonderfully safe and effective fish oil as a nutritional supplement, but there won't be a sexy drug representative to sell it, nor an expensive dinner and payment for a trip to Orlando to hear about it. << Older posts Newer posts >> Newer posts12...262728293031323334...121122Older posts
