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 William Davis (15) Fifty years ago, diabetes was a relatively uncommon disease. Today, the latest estimates are that 50% of Americans are now diabetic or pre-diabetic. There are some obvious explanations: excess weight, inactivity, the proliferation of fructose in our diets. It is also my firm belief that the diets advocated by official agencies, like the USDA, the American Heart Association, the American Dietetic Association, and the American Diabetes Association, have also contributed with their advice to eat more “healthy whole grains.” When I was a kid, I ate Lucky Charms® or Cocoa Puffs® for breakfast, carried Hoho’s® and Scooter Pies® in my lunchbox, along with a peanut butter sandwich on white bread. We ate TV dinners, biscuits, instant mashed potatoes for dinner. Back then, it was a matter of novelty, convenience, and, yes, taste. What did we do to our pancreases eating such insulin-stimulating foods through childhood, teenage years, and into early adulthood? Did our eating habits as children and young adults create diabetes many years later? Could sugary breakfast cereals, snacks, and candy in virtually unlimited quantities have impaired our pancreas’ ability to produce insulin, leading to pre-diabetes and diabetes many years later? A phenomenon called glucose toxicity underlies the development of diabetes and pre-diabetes. Glucose toxicity refers to the damaging effect that high blood sugars (glucose) have on the delicate beta cells of the pancreas, the cells that produce insulin. This damage isirreversible: once it occurs, it cannot be undone, and the beta cells stop producing insulin and die. The destructive effect of high glucose levels on pancreatic beta cells likely occurs through oxidative damage, with injury from toxic oxidative compounds like superoxide anion and peroxide. The pancreas is uniquely ill-equipped to resist oxidative injury, lacking little more than rudimentary anti-oxidative protection mechanisms. Glucose toxicity that occurs over many years eventually leaves you with a pancreas that retains only 50% or less of its original insulin producing capacity. That’s when diabetes develops, when impaired pancreatic insulin production can no longer keep up with the demands put on it. (Interesting but unanswered question: If oxidative injury leads to beta cell dysfunction and destruction, can antioxidants prevent such injury? Studies in cell preparations and animals suggest that anti-oxidative agents, such as astaxanthin and acetylcysteine, may block beta cell oxidative injury. However, no human studies have yet been performed. This may prove to be a fascinating area for future.)Now that 50% of American have diabetes or pre-diabetes, how much should we blame on eating habits when we were younger? I would wager that eating habits of youth play a large part in determining potential for diabetes or pre-diabetes as an adult. The lesson: Don’t allow children to repeat our mistakes. Letting them indulge in a lifestyle of soft drinks, candy, pretzels, and other processed junk carbohydrates has the potential to cause diabetes 20 or 30 years later, shortening their life by 10 years. Kids are not impervious to the effects of high sugar, including the cumulative damaging effects of glucose toxicity.
Saturated fat and large LDL 16. February 2010 William Davis (44) Here's a half-truth I often encounter in low-carb discussions:Saturated fat increases large LDL particlesFor those of you unfamiliar with the argument, I advocate a low-carbohydrate approach, specifically elimination of all wheat, cornstarch, and sugars, to reduce expression of the small LDL pattern (not to mention reduction of triglycerides, relief from acid reflux and irritable bowel, weight loss, various rashes, diabetes, etc). Small LDL particles have become the most common cause for heart disease in the U.S., exploding on the scene ever since agencies like the USDA and American Heart Association have been advising the public to increase consumption of "healthy whole grains." This has led some to make the pronouncement that saturated fat increases large LDL, thereby representing a benign effect. Is this true? It is true, but only partly. Let me explain. There are two general categories of factors causing small LDL particles: lifestyle (overweight, excess carbohydrates) and genetics (e.g., variants of the gene coding for cholesteryl-ester transfer protein, or CETP). If small LDL is purely driven by excess carbohydrates, then adding saturated fat will reduce small LDL and increase large LDL. If, on the other hand, your small LDL is genetically programmed, then saturated fat will increase small LDL. In other words, saturated fat tends to increase the dominant or genetically-determined form of LDL. If your dominant genetically-determined form is small, then saturated fat increases small LDL particles. So to say that saturated fat increases large LDL is an oversimplification, one that can have dire consequences in the wrong situation.
Is glycemic index irrelevant? 14. February 2010 William Davis (20) University of Toronto nutrition scientist, Dr. David Jenkins, was the first to quantify the phenomenon of "glycemic index," describing how much blood sugar increased over 90 minutes compared to glucose. The graph is from their 1981 study, The glycemic index of foods: a physiologic basis for carbohydrate exchange. The research originated with an effort to characterize carbohydrates for diabetics to gain better control over blood sugar.Since Dr. Jenkins’ original work, thousands of clinical studies have been performed by others exploring this concept. The food industry has also devoted plenty of effort exploiting it (e.g., low-glycemic index noodles, low-glycemic index cereals, etc.). Most Americans are now familiar with the concept of glycemic index. You likely know that table sugar has a high glycemic index (60), increasing blood sugar to a similar degree as white bread (glycemic index 71). Oatmeal (slow-cooked) has a lower glycemic index (48), since it increases blood sugar less than white bread. A number of studies have shown that when low glycemic index foods replace high glycemic index foods (e.g., whole wheat bread in place of cupcakes), people are healthier: less diabetes, less heart attack, less high blood pressure. Books have been written about glycemic index, touting its benefits for health and weight control. Health-conscious people will try to substitute low-glycemic index foods for high-glycemic index foods. So what’s not to like here? There are several fundamental flaws with the notion that low-glycemic index foods are good for you:1) Check your blood sugar after a low-glycemic index food like oatmeal. Most non-diabetic adults will show blood sugars in the 140 to 200 mg/dl range. The more central (visceral) fat you have, the higher the value will be. In other words, an apparently “healthy” whole grain food like oatmeal can generate extravagantly high blood sugars. Repeated high blood sugars of 125 mg/dl or greater after eating increase heart disease risk by 50%. 2) Foods like whole wheat pasta have a low glycemic index because the blood sugar effect over the usual 90 minutes is increased to a lesser degree. The problem is that it remains increased for an extended period of up to several hours. In other words, the blood sugar-increasing effect of pasta, even whole grain, is long and sustained. 3) Low-glycemic index foods trigger other abnormalities, such as small LDL particles, triglycerides, and c-reactive protein (a measure of inflammation). While they are not as bad as high-glycemic index foods, they are still quite potent triggers. Low-glycemic index foods trigger the very same responses as high-glycemic index foods—they’re just less bad. But less bad does not equate to good. Low-glycemic index foods cause weight gain, trigger appetite, increase blood pressure, and lead to the patterns that cause heart disease. High-glycemic index foods are bad for you. This includes foods made with white flour (bagels, white bread, pretzels). Low-glycemic foods (whole grain bread, whole wheat crackers, whole wheat pasta) are less bad for you—but they are not necessarily good. Don’t be falsely reassured by foods because they are billed as “low-glycemic index.” View low-glycemic index foods as indulgences, something you might have once in a while, since a slice of whole grain bread is really not that different from a icing-covered cupcake.
What Mr. Clinton did NOT do 12. February 2010 William Davis (36) You've likely already heard that former President Bill Clinton underwent a heart catheterization today during which one of the bypass grafts to his coronary arteries was found to be occluded. The original coronary artery was therefore stented. Dr. Alan Schwartz, Mr. Clinton's cardiologist, announced to the gathered press that Mr. Clinton had followed a good diet, had adopted a regular exercise program, but that his condition is a "chronic disease" like hypertension that is not cured by these efforts. Needing a stent just 6 years after four bypass grafts are inserted is awfully soon. I would propose that it has less to do with having a "chronic disease" and more to do with all the things that Mr. Clinton likely is NOT doing. (In addition to all the other things that Mr. Clinton did not do.) In other words, in the Track Your Plaque world, procedures are a rarity, heart attacks virtually unheard of. I would wager that Mr. Clinton has been doing none of the following: --Taking fish oil. Or, if his doctor was "advanced" enough to have advised him to take fish oil, not taking enough. --Vitamin D--Followers of the Heart Scan Blog already know that vitamin D is the most incredible health find of the last 50 years, including its effects on reducing heart disease risk. Unless Mr. Clinton runs naked in a tropical sun, he is vitamin D deficient. A typical dose for a man his size is 8000 units per day (gelcap only!). --Eating a true heart healthy diet. I'll bet Mr. Clinton's doctor, trying to do the "right" thing, follows the prudent course of advising a "balanced diet" that is low in fat--you know, the diet that causes heart disease. Judging by Mr. Clinton's body shape (central body fat), it is a virtual certainty that he conceals a severe small LDL pattern, the sort that is worsened by grains, improved with their elimination.--Making sure that hidden causes are addressed--In addition to the "hidden" small LDL, lipoprotein(a) is another biggie. Lp(a) tends to be the province of people with greater than average intelligence. I believe Mr. Clinton qualifies in this regard. I would not be at all surprised if Mr. Clinton conceals a substantial lipoprotein(a) pattern, worsened in the presence of small LDL. --Controlling after-meal blood sugars--Postprandial (after-eating) blood sugars are a major trigger for atherosclerotic plaque growth. There are easy-to-follow methods to blunt the after-meal rise of blood sugar.

May 2015 William Davis (0) Our efforts to obtain prebiotic fibers/resistant starches, as discussed in the Cureality Digestive Health Track, to cultivate healthy bowel flora means recreating the eating behavior of primitive humans who dug in the dirt with sticks and bone fragments for underground roots and tubers, behaviors you can still observe in extant hunter-gatherer groups, such as the Hadza and Yanomamo. But, because this practice is inconvenient for us modern folk accustomed to sleek grocery stores, because many of us live in climates where the ground is frozen much of the year, and because we lack the wisdom passed from generation to generation that helps identify which roots and tubers are safe to eat and which are not, we rely on modern equivalents of primitive sources. Thus, green, unripe bananas, raw potatoes and other such fiber sources in the Cureality lifestyle. There is therefore no need to purchase prebiotic fibers outside of your daily effort at including an unripe green banana, say, or inulin and fructooligosaccharides (FOS), or small servings of legumes as a means of cultivating healthy bowel flora. These are powerful strategies that change the number and species of bowel flora over time, thereby leading to beneficial health effects that include reduced blood sugar and blood pressure, reduction in triglycerides, reduced anxiety and improved sleep, and reduced colon cancer risk. HOWEVER, convenience can be a struggle. Traveling by plane, for example, makes lugging around green bananas or raw potatoes inconvenient. Inulin and FOS already come as powders or capsules and they are among the options for a convenient, portable prebiotic fiber strategy. But there are others that can be purchased. This is a more costly way to get your prebiotic fibers and you do not need to purchase these products in order to succeed in your bowel flora management program. These products are therefore listed strictly as a strategy for convenience. Most perspectives on the quality of human bowel flora composition suggest that diversity is an important feature, i.e., the greater the number of species, the better the health of the host. There may therefore be advantage in varying your prebiotic routine, e.g., green banana on Monday, inulin on Tuesday, PGX (below) on Wednesday, etc. Beyond providing convenience, these products may introduce an added level of diversity, as well. Among the preparations available to us that can be used as prebiotic fibers:PGXWhile it is billed as a weight management and blood sugar-reducing product, the naturally occurring fiber--α-D-glucurono-α-D-manno-β-D-manno- β-D-gluco, α-L-gulurono-β-D mannurono, β-D-gluco-β- D-mannan--in PGX also exerts prebiotic effects (evidenced by increased fecal butyrate, the beneficial end-product of bacterial metabolism). PGX is available as capsules or granules. It also seems to exert prebiotic effects at lower doses than other prebiotic fibers. While I usually advise reaching 20 grams per day of fiber, PGX appears to exert substantial effects at a daily dose of half that quantity. As with all prebiotic fibers, it is best to build up slowly over weeks, e.g., start at 1.5 grams twice per day. It is also best taken in two or three divided doses. (Avoid the PGX bars, as they are too carb-rich for those of us trying to achieve ideal metaobolic health.)PrebiotinA combination of inulin and FOS available as powders and in portable Stick Pacs (2 gram and 4 gram packs). This preparation is quite costly, however, given the generally low cost of purchasing chicory inulin and FOS separately. AcaciaAcacia fiber is another form of prebiotic fiber. RenewLife and NOW are two reputable brands. Isomalto-oligosaccharidesThis fiber is used in Quest bars and in Paleo Protein Bars. With Quest bars, choose the flavors without sucralose, since it has been associated with undesirable changes in bowel flora. There you go. It means that there are fewer and fewer reasons to not purposefully cultivate healthy bowel flora and obtain all the wonderful health benefits of doing so, from reduced blood pressure, to reduced triglycerides, to deeper sleep. Disclaimer: I am not compensated in any way by discussing these products. How Not To Have An Autoimmune Condition 20. April 2015 William Davis (0) Autoimmune conditions are becoming increasingly common. Estimates vary, but it appears that at least 8-9% of the population in North America and Western Europe have one of these conditions, with The American Autoimmune Related Diseases Association estimating that it’s even higher at 14% of the population. The 200 or so autoimmune diseases that afflict modern people are conditions that involve an abnormal immune response directed against one or more organs of the body. If the misguided attack is against the thyroid gland, it can result in Hashimoto’s thyroiditis. If it is directed against pancreatic beta cells that produce insulin, it can result in type 1 diabetes or latent autoimmune diabetes of adults (LADA). If it involves tissue encasing joints (synovium) like the fingers or wrists, it can result in rheumatoid arthritis. It if involves the liver, it can result in autoimmune hepatitis, and so on. Nearly every organ of the body can be the target of such a misguided immune response. While it requires a genetic predisposition towards autoimmunity that we have no control over (e.g., the HLA-B27 gene for ankylosing spondylitis), there are numerous environmental triggers of these diseases that we can do something about. Identifying and correcting these factors stacks the odds in your favor of reducing autoimmune inflammation, swelling, pain, organ dysfunction, and can even reverse an autoimmune condition altogether.Among the most important factors to correct in order to minimize or reverse autoimmunity are:Wheat and grain eliminationIf you are reading this, you likely already know that the gliadin protein of wheat and related proteins in other grains (especially the secalin of rye, the hordein of barley, zein of corn, perhaps the avenin of oats) initiate the intestinal “leakiness” that begins the autoimmune process, an effect that occurs in over 90% of people who consume wheat and grains. The flood of foreign peptides/proteins, bacterial lipopolysaccharide, and grain proteins themselves cause immune responses to be launched against these foreign factors. If, for instance, an autoimmune response is triggered against wheat gliadin, the same antibodies can be aimed at the synapsin protein of the central nervous system/brain, resulting in dementia or cerebellar ataxia (destruction of the cerebellum resulting in incoordination and loss of bladder and bowel control). Wheat and grain elimination is by far the most important item on this list to reverse autoimmunity.Correct vitamin D deficiencyIt is clear that, across a spectrum of autoimmune diseases, vitamin D deficiency serves a permissive, not necessarily causative, role in allowing an autoimmune process to proceed. It is clear, for instance, that autoimmune conditions such as type 1 diabetes in children, rheumatoid arthritis, and Hashimoto’s thyroiditis are more common in those with low vitamin D status, much less common in those with higher vitamin D levels. For this and other reasons, I aim to achieve a blood level of 25-hydroxy vitamin D level of 60-70 ng/ml, a level that usually requires around 4000-8000 units per day of D3 (cholecalciferol) in gelcap or liquid form (never tablet due to poor or erratic absorption). In view of the serious nature of autoimmune diseases, it is well worth tracking occasional blood levels.Supplement omega-3 fatty acidsWhile omega-3 fatty acids, EPA and DHA, from fish oil have proven only modestly helpful by themselves, when cast onto the background of wheat/grain elimination and vitamin D, omega-3 fatty acids compound anti-inflammatory benefits, such as those exerted via cyclooxygenase-2. This requires a daily EPA + DHA dose of around 3600 mg per day, divided in two. Don’t confuse EPA and DHA omega-3s with linolenic acid, another form of omega-3 obtained from meats, flaxseed, chia, and walnuts that does not not yield the same benefits. Nor can you use krill oil with its relatively trivial content of omega-3s.Eliminate dairyThis is true in North America and most of Western Europe, less true in New Zealand and Australia. Autoimmunity can be triggered by the casein beta A1 form of casein widely expressed in dairy products, but not by casein beta A2 and other forms. Because it is so prevalent in North America and Western Europe, the most confident way to avoid this immunogenic form of casein is to avoid dairy altogether. You might be able to consume cheese, given the fermentation process that alters proteins and sugar, but that has not been fully explored.Cultivate healthy bowel floraPeople with autoimmune conditions have massively screwed up bowel flora with reduced species diversity and dominance of unhealthy species. We restore a healthier anti-inflammatory panel of bacterial species by “seeding” the colon with high-potency probiotics, then nourishing them with prebiotic fibers/resistant starches, a collection of strategies summarized in the Cureality Digestive Health discussions. People sometimes view bowel flora management as optional, just “fluff”–it is anything but. Properly managing bowel flora can be a make-it-or-break-it advantage; don’t neglect it.There you go: a basic list to get started on if your interest is to begin a process of unraveling the processes of autoimmunity. In some conditions, such as rheumatoid arthritis and polymyalgia rheumatica, full recovery is possible. In other conditions, such as Hashimoto’s thyroiditis and the pancreatic beta cell destruction leading to type 1 diabetes, reversing the autoimmune inflammation does not restore organ function: hypothyroidism results after thyroiditis quiets down and type 1 diabetes and need for insulin persists after pancreatic beta cell damage. But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery Five Powerful Ways to Reduce Blood Sugar 4. April 2015 William Davis (0) Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess. If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics. Among the most powerful and effective strategies to reduce blood sugar:1) Eat no wheat nor grainsRecall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.2) Add no sugars, avoid high-fructose corn syrupThis should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.3) Vitamin DBecause vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.4) Restore bowel floraAs cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)5) ExerciseBlood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health. This is our core mission in Cureality. A nice side benefit: information from Cureality is not accompanied by advertisements from Merck, Pfizer, Kelloggs, Kraft, or Cadbury Schweppes.

But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery
Five Powerful Ways to Reduce Blood Sugar 4. April 2015 William Davis (0) Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess. If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics. Among the most powerful and effective strategies to reduce blood sugar:1) Eat no wheat nor grainsRecall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.2) Add no sugars, avoid high-fructose corn syrupThis should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.3) Vitamin DBecause vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.4) Restore bowel floraAs cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)5) ExerciseBlood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health.
