Omega-6 / omega-3 ratio 7. August 2008 William Davis (11) Most of us already know that the intake of omega-6 fatty acids in the American diet has gone overboard, much at the expense of the omega-3 fraction. This occurred as a result of the misguided advice of the 1970s and 1980s to eat polyunsaturated oils like corn, sunflower, and safflower, because of their presumed cholesterol-reducing properties compared to saturated fats. However, more recent examinations of this advice have suggested that the omega-6 fraction of oils present in polyunsaturated oils may amplify arachidonic acid and other inflammatory patterns despite the reduction in cholesterol (total and LDL). Dr. Artemis Simopoulos of the Center for Genetics, Nutrition and Health in Washington, D.C. has written extensively on the role of omega-6 and omega-3 fatty acids in diet. In a review entitled The Importance of the Omega-6/Omega-3 Fatty Acid Ratio in Cadiovacular Disease and Other Chronic Disease , Dr. Simopoulos collects the following comparison of omega-6 to omega-3 ratios from various populations: Paleolithic humans 0.79Greece (prior to 1960) 1.00-2.00Current Japan 4.00Current India, rural 5-6.1Current United Kindom and northern Europe 15.00Current United States 16.74Current India, urban 38-50(The numbers refer to the ratio of omega-6 to omega-3 intake.)If we believe the observations of Dr. Loren Cordain and others, while paleolithic man died of trauma and infectious diseases, they did not die of heart disease. Paleolithic human intake of omega-3 exceeded that of omega-6. Likewise, the traditionally low cardiac event regions of the world like Japan and Greece have less omega-3 intake than Paleolithic man, but still many times more than the U.S. and U.K. Worst of all with an enormous preponderance of omega-6 over omega-3 are urban Indians, who experience among the highest rates of heart disease in the world. Just for perspective, let's assume you eat an 1800 calorie per day diet, of which 30% of calories come from fat. This would amount to 540 calories per day from fat. With 9 calories per gram of fat, this means that there are 60 grams, or 60,000 mg, of fat in your diet per day. Paleolithic man has been found to have existed on a diet consisting of 21% of calories from fats. Again assuming an 1800 calorie per day diet, that comes to 42 grams of fat per day (42,000 mg). If we were to try to recreate the Paleolithic fat composition of diet, we would ingest 21,000 mg of omega-3 fatty acids (EPA, DHA, linolenic acid) per day. Even recreating a Japanese experience with a 4:1 ratio, it would mean 8400 mg of omega-3 per day. (Curiously, this does not agree with all estimates of Japanese intake of omega-3s.)No matter how you look at it, cultures with lower rates of cardiovascular disease take in greater--much greater--quantities of omega-3 fatty acids. So don't complain about your six fish oil capsules (usually containing 6000 mg of total oil, 1800 mg omega-3s)!
Dr. Bernadine Healy on heart scans 5. August 2008 William Davis (1) A Heart Scan Blog reader brought the following tidbit to my attention. Cardiologist and now writer for U.S. News and World Report, Dr. Bernadine Healy, wrote this editorial, a glowing endorsement of heart scans: The approach is beautifully simple. Calcium accumulates in advanced plaques, so calcium visible in the heart's arteries indicates atherosclerosis. An exploding number of studies in the past few years have unequivocally shown that the calcium score predicts both heart attack and sudden death. As a generalization, patients with scores between 100 and 400 face three to four times the risk of a heart attack or death compared with others at the same age with a zero score. Over 400, that elevated risk more than doubles.Most doctors rely instead on the Framingham calculator, which estimates a symptom-free person's risk of a heart attack in the next 10 years based on smoking history, blood pressure, cholesterol levels, sex, and age. It's available free online from the National Institutes of Health. Most people taking the test will have minimal or no coronary disease, though risk estimates over 9 percent should inspire vigorous preventive efforts. For some, however, coronary heart disease is sneaky, and Framingham will underestimate what lies ahead. Roughly half of those who suffer a major heart attack or sudden coronary death are symptom free. Calcium scores are additive to Framingham; they pick up the individual surprises by using X-ray vision to look inside the heart. No wonder insurance companies are scrambling to use coronary calcium scores—life insurers, that is.Dr. Bernadine Healy is no small-time player. In addition to her academic credentials, she is former chief of the National Institutes of Health (the first woman to hold the influential post), former head of the American Red Cross, and former deputy director of the White House Office of Science and Technology Policy under the Reagan administration. An endorsement of CT heart scans, though written under the guise of a probing editorial, will do an enormous amount of good to overcome the hurdles in gaining wider acceptance of heart scans.Those of us applying heart scans in everyday practice have long appreciated their enormous power to detect and track coronary plaque. Framingham scoring can't even touch the certainty and quantification provided by heart scans in day-to-day life. Hundreds of studies have validated their use, but they still suffer from lying in the shadows of the procedural bullies aiming to boost the number of heart catheterizations, angioplasties, stents, bypass surgeries. Dr. Healy, a voice with great weight, not just a political figure but also a cardiologist and scientist, has done a great service to broadcast the message of heart scanning.
Mercury and fish oil 2. August 2008 William Davis (9) As time passes, the dose of fish oil advocated in the Track Your Plaque program is going upward. While epidemiologic studies, like the Chicago Western Electric Study and the Nurses' Health Study suggest that decreases in mortality from heart disease begin by just eating fish a couple times per month, there are newer data that suggest greater quantities confer greater benefits. In the last Heart Scan Blog post, I discussed the recently-released ERA JUMP Study that demonstrated a relationship between higher omega-3 fatty acid blood content and reduced quantities of carotid and coronary plaque. The JELIS Study demonstrated a 19% reduction in cardiovascular events when fish-consuming Japanese added 1800 mg of EPA (only). However, the suggestion that increased quantities of fish oil potentially yield greater protection from heart attack and facilitate coronary plaque regression is also stirring up worries about mercury exposure. So I dug up a Heart Scan Blog post from a year ago that discussed this issue and reprint it here. I often get questions about the mercury content in fish oil. I've even had patients come to the office saying their primary care doctor told them to stop fish oil to avoid mercury poisoning. Manufacturers of fish oil also make claims that this product or that ("super-concentrated", "pharmaceutical grade", "purified", etc.) is purer or less contaminated than competitors' products. The manufacturers of the "drug" Omacor [now Lovaza], or prescription fish oil, have added to the confusion by suggesting that their product is the most pure of all, since it is the most concentrated of any fish oil preparation (900 mg EPA+DHA per capsule). They claim that "OMACOR is naturally derived through a unique, patented process that creates a highly concentrated, highly purified prescription medicine. By prescribing OMACOR® (omega-3-acid ethyl esters), a prescription omega-3, your doctor is giving you a concentrated and reliable omega-3. Each OMACOR capsule contains 90% omega-3 acids (84% EPA/DHA*). Nonprescription omega-3 dietary supplements typically contain only 13%-63% EPA/DHA." How much truth is there in these concerns?Let's go to the data published by the USDA, FDA, and several independent studies. Let's add to that the independent (and therefore presumably unbiased) analyses provided by Consumer Reports and Consumer Labs (www.consumerlab.com). How much mercury has been found in fish oil supplements?None.This is different from the mercury content of whole fish that you eat. Predatory fish that are at the top of the food chain and consume other fish and thereby concentrate organic methyl mercury, the toxic form of mercury. Thus, shark, swordfish, and King mackerel are higher in mercury than sardines, herring, and salmon. The mercury content of fish oil capsules have little to do with the method of processing and much more with the animal source of oil. Fish oil is generally obtained from sardines, salmon, and cod, all low in mercury. Fish oil capsules are not prepared from swordfish or shark. Thus, concerns about mercury from fish oil--regardless of brand--are generally unfounded, according to the best information we have. Eating whole fish--now that's another story for another time. But you and I can take our fish oil to reduce triglycerides, VLDL, IDL, small LDL, and heart attack risk without worrying about mercury.I am not advocating ad libitum eating of fish. Sadly, this may be related to excessive accumulation of contaminants. I am suggesting that greater quantities of omega-3 fatty acids from relatively contaminant- and mercury-free fish oil capsules. More on this in an upcoming webinar on the Track Your Plaque website: Fish Oil and the Track Your Plaque Program - Is More Better?
ERA JUMP: Omega-3 fatty acids and plaque 1. August 2008 William Davis (5) The results of the uniquely-constructed ERA JUMP Study were just released, a fascinating study of the relationship of omega-3 fatty acids to coronary and carotid plaque.The study adds insight into why the Japanese experience only one third of the heart attacks of Americans, and why Japan occupies the bottom of the list for least heart attacks among all developed countries. The Electron-Beam Tomography, Risk Factor Assessment Among Japanese and U.S. Men in the Post-World War II Birth Cohort Study (ERA JUMP), a collaborative U.S.-Japanese effort, compared three groups of men: -- 281 Japanese men living in Japan-- 306 non-Japanese men living in the U.S. (Pittsburgh, Pennsylvania)-- 303 Japanese Americans (having both parents Japanese without “ethnic admixture”) living in Hawaii. The last group represents a group that is genetically similar to the group in Japan, but exposed to an American diet and lifestyle. Three main measures were compared: -- Blood levels of omega-3 fatty acids, EPA and DHA)-- Carotid intimal-medial thickness (CIMT, the thickness of the carotid artery lining that can serve as an index of body-wide atherosclerosis)-- Coronary calcium (heart scan) scores. Interestingly, at the start of the study, the Japanese men possessed an overall cardiovascular risk profile worse than the Americans: Though more slender (BMI 23.6), Japanese men were more likely to be smokers, alcohol drinkers, had more high blood pressure, and were less likely to take cholesterol medications. The Americans, conversely, although heavier (BMI 27.9), were less likely to be smokers and drinkers, and had a four-fold greater use of cholesterol medications. The Japanese Americans were the most likely to be hypertensive, diabetic, with a similar proportion of overweight as the non-Japanese Americans. Despite the overall greater heart disease risk for profile for Japanese men, compared to non-Japanese Americans they had 10% less CIMT. In addition, only 9.3% of Japanese men had abnormal coronary calcium scores vs. 26.1% of non-Japanese Americans. Japanese-Americans were the worst, however, with nearly 10% more CIMT than non-Japanese Americans and 31.4% with abnormal calcium scores. The most intriguing finding of all was the fact that, of all the various groups and degrees of atherosclerosis, whether gauged via CIMT or coronary calcium scores, the blood level of omega-3 fatty acids was inversely related, i.e., the greater the omega-3 blood level, the less plaque by either measure was detected. Japanese men had the highest omega-3 blood levels: twice that of the non-Japanese Americans. The Japanese-Americans had levels only slightly greater than non-Japanese Americans. While other studies, like the GISSI Prevenzione study, have persuasively demonstrated that omega-3 fatty acids substantially reduce heart attack, a weak link in the omega-3 argument has been a study that links greater omega-3 intake with less atherosclerosis. The unique construction of the ERA JUMP Study, employing two groups with sharply different omega-3 intakes, very powerfully argues for the plaque-inhibiting effects of this fraction of fats. How much omega-3 fatty acids do Japanese people eat? Estimates vary, depending on part of the country, coastal vs. inland, age, etc., but Japanese tend to ingest anywhere from 5 to 15-times more omega-3 fatty acids than Americans. The actual intake of omega-3 fatty acids (EPA +DHA) in Japanese ranges from 850 to 3100 mg per day.
Mediterranean diet and blood sugar 31. July 2008 All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in Wheat "debate" on CBC 11. October 2011 William Davis (29) "Many Canadians plan warm buns, stuffing and pie for their Thanksgiving meals tonight. But I'll speak with a cardiologist who thinks we have no reason to be thankful for any food that contains wheat. William Davis says our daily bread is making us fat and sick."That's the introduction to my recent interview and debate on CBC, the Canadian public radio system, aired on the Canadian Thanksgiving. Arguing the other side was Dr. Susan Whiting, an academic nutritionist. (I use the word "arguing" loosely, since she hardly argued the issues, certainly hadn't read the book, but was content to echo the conventional line that whole grains are healthy and cutting out a food group is unhealthy.) I do have to give credit to the Canadian media, including the CBC, who have been hosting some rough-and-tumble discussions about the entire wheat question despite Canada being a world exporter of wheat. I recently participated in another debate with a PhD nutrition expert from Montreal who, in response to my assertion that the genetically-altered high-yield, semi-dwarf strains have changed the basic composition of wheat, argued that the creation of the 2-foot tall semi-dwarf strain was a convenience created so that farmers could see above their fields--no kidding. I stifled my laugh. (The semi-dwarf variants were actually created to compensate for the heavy seed head that develops with vigorous nitrate fertilization that buckles 4 1/2-foot tall wheat stalk, making harvesting and threshing impossible, a process farmers call "lodging." The 2-foot tall semi-dwarf thick, stocky stalk is strong enough to resist lodging.) In short, debating the nutrition "experts" on this question has been tantamount to arguing with a school age child on the finer points of quantum physics. There has not yet been any real objection raised on the basic arguments against modern genetically-altered wheat. Modern semi-dwarf wheat is, and remains, an incredibly bad creation of the genetics laboratories of the 1970s. It has no business on the shelves of your grocery store nor on the cupboards in your home. Carrot Cake 5. October 2011 William Davis (14) This is among my favorite recipes from the Wheat Belly book. I reproduce it here for those of you who read the Kindle or audio version and therefore didn't get the recipes.I made this most recently this past weekend. It was gone very quickly, as even the 13-year old gobbled it up.(I reduced the sour cream in this version from 8 to 6 oz to reduce cooking time. Also, note that anyone trying to avoid dairy can substitute more coconut milk, i.e., the thicker variety, in equivalent quantities.)Makes 8-10 servings Ingredients:Cake:2 cups carrots, finely grated1 cup chopped pecans1 cup coconut flour1 tablespoon ground flaxseed2 teaspoons ground cinnamon1 teaspoon allspice1 teaspoon nutmeg1 teaspoon baking powder2 tablespoons freshly grated orange peelSweetener equivalent to ½ cup sugar (e.g., 4 tablespoons Truvia)½ teaspoon sea salt4 eggs1/2 cup butter or coconut oil, melted2 teaspoons vanilla extract½ cup coconut milk6 ounces sour creamIcing:8 ounces cream cheese or Neufchâtel cheese, softened1 teaspoon lemon juice1 tablespoon Truvía or 1/8 teaspoon stevia extract powder or ¼ cup SplendaPreheat oven to 325° degrees F. Grate carrots and set aside.Combine coconut flour, flaxseed, cinnamon, nutmeg, baking powder, orange peel, sweetener, and salt in large bowl and mix by hand.Put eggs, butter or coconut oil, vanilla coconut milk, and sour cream in mixing bowl; mix by hand.

Add lemon juice and sweetener and mix thoroughly. Spread on cake. Why wheat makes you fat 1. October 2011 William Davis (32) How is it that a blueberry muffin or onion bagel can trigger weight gain? Why do people who exercise, soccer Moms, and other everyday people who cut their fat and eat more "healthy whole grains" get fatter and fatter? And why weight gain specifically in the abdomen, the deep visceral fat that I call a "wheat belly"?There are several fairly straightforward ways that wheat in all its varied forms--whole wheat bread, white bread, multigrain bread, sprouted bread, sourdough bread, pasta, noodles, bagels, ciabatta, pizza, etc. etc.--lead to substantial weight gain:High glucose and high insulin--This effect is not unique to wheat, but shared with other high-glycemic index foods (yes: whole wheat has a very high-glycemic index) like cornstarch and rice starch (yes, the stuff used to make gluten-free foods). The high-glycemic index means high blood glucose triggers high blood insulin. This occurs in 90- to 120-minute cycles. The high insulin that inevitably accompanies high blood sugar, over time and occurring repeatedly, induces insulin resistance in the tissues of the body. Insulin resistance causes fat accumulation, specifically in abdominal visceral fat, as well as diabetes and pre-diabetes. The more visceral fat you accumulate, the worse insulin resistance becomes; thus the vicious cycle ensues. Cycles of satiety and hunger--The 90- to 120-minute glucose/insulin cycle is concluded with a precipitous drop in blood sugar. This is the foggy, irritable, hungry hypoglycemia that occurs 2 hours after your breakfast cereal or English muffin. The hypoglyemia is remedied with another dose of carbohydrate, starting the cycle over again . . . and again, and again, and again. Gliadin proteins--The gliadin proteins unique to wheat, now increased in quantity and altered in amino acid structure from their non-genetically-altered predecessors, act as appetite stimulants. This is because gliadins are degraded to exorphins, morphine-like polypeptides that enter the brain. Exorphins can be blocked by opiate-blocking drugs like naltrexone. A drug company has filed an application with the FDA for a weight loss indication for naltrexone based on their clinical studies demonstrating 22 pounds weight loss after 6 months treatment. Overweight people given an opiate blocker reduce calorie intake 400 calories per day. But why? There's only one food that yields substantial quantities of opiate-like compounds in the bloodstream and brain: wheat gliadin. Leptin resistance--Though the data are preliminary, the lectin in wheat, wheat germ agglutinin, has the potential to block the leptin receptor. Leptin resistance is increasingly looking like a fundamental reason why people struggle to lose weight. This might explain why eliminating, say, 500 calories of wheat consumption per day yields 3500 calories of weight loss. And, as in many things wheat, the whole is greater than the sum of the parts. Despite all we know about this re-engineered thing called wheat, eliminating it yields health benefits, including weight loss, that seem to be larger than what you'd predict with knowledge of all its nasty little individual pieces. Just who is "Real Facts 2000"? 29. September 2011 William Davis (38) This is an example of what seems to be developing over at Amazon.com, posted as a "book review": The author has no credentials, no credibility, just a small cult of terribly misinformed followers. Don't be fooled by the high volume screech against wheat and grains. Allegations of "secret ingredients in wheat" to make you eat more, or comparisons to cigerettes. Seriously?! For over 8000 years wheat has sustained and grown human kind, oh and it tastes good when mixed with a little water and yeast. Every nutritionist and serious medical professional will tell you that bread is the most economical and safe source of essential nutrients. In fact, bread is handed out in natural disasters because it sustains life without food safety issues or requiring refrigeration. And now, suddenly it will kill you. Comical! This book is such a bone headed, misinformed way to just scare people into not eating. As for secret ingredients, humm, apparently the author is ignorant of the food laws that regulate everything that goes into food and on food labels. Unlike some enforcement agencies, the FDA has some serious teeth behind its enforcement. As for frankenwheat, again seriously?! Wheat, due to its ubiquitous presence in the world is treated as sacrosant from any GMO research or development. If you need real, science based information on healthy eating, check out [...] and leave this book and its cult in the compound.If you recognize the wording and tone, you will readily recognize the footprints of the Wheat Lobby here. "Terribly misinformed followers"? . . . Hmmm. "Food laws"? I didn't realize that eating more "healthy whole grains" was a . . . law?Make no mistake: There are people and organizations who have a heavy stake in your continued consumption of the equivalent of 300 loaves of bread per year. There are people and organizations (read: pharmaceutical industry) who have a big stake on the "payoff" of your continued consumption of "healthy whole grains." This is not a book review; this is part of a concerted, organized campaign to discredit a message that needs to be heard. Anybody from the media listening? Almonds are the new wheat 29. September 2011 William Davis (31) Once you eliminate this genetically-altered Frankengrain called modern wheat, the diet should center around vegetables, nuts, healthy oils like olive and coconut, fish, meats, cheese, olives, avocados and other real whole foods. This is, in fact, the diet that I have advocated in my heart disease prevention practice, as well as my online program for prevention and reversal of heart disease. But what if you'd like a piece of cheesecake or a nice slice of dessert bread---but you don't want to gain two pounds, spend 48 hours in the bathroom suffering with diarrhea and cramps, 3 weeks of joint pains and leg swelling, wade through mental "fog," anxiety, and rage just because you had that momentary indulgence---as you would with wheat? That's why I've been focusing on recipes that allow you to have something familiar, e.g., chocolate coconut bread or biscotti, but using ingredients that will not generate the metabolic contortions triggered by wheat. On perusing these recipes, you will notice that there are recurring ingredient themes. Many of the same ingredients pop up time and again. Among the most frequent, versatile, user-friendly, and tasty: Almonds. You can use almonds as ground whole almonds, ground blanched almonds for a finer texture, ground roasted almonds, almond butter (though, for maximum health benefits, I prefer the ground whole almonds). Ground almonds allow you to recreate muffins, breads, scones, pizza crust, pie crust, biscotti, and cookies with health benefits that exceed that of whole wheat---but with none of the downside: no weight gain, no high blood sugar, no triggering of small LDL particles (#1 cause of heart disease in the U.S.), no accumulation of visceral fat, no appetite stimulation. In short, you just have your chocolate almond biscotti or mocha cupcake and enjoy it, no health price to pay. So I call almonds the new wheat, except better. Being regular is dangerous to your health 25. September 2011 William Davis (21) No, I'm not referring to your daily morning ritual in the bathroom. I'm talking about heart rate.Counterintuitively, a perfectly regular heart rate is a marker of poor health. People with perfect regularity of heart rate have more heart attacks, for instance.Regularity of heart rate occurs more commonly in people with hypertension and other metabolic derangements, and it signals increased risk for both heart attack and death. A perfectly regular heart rate, i.e., no variation in the time interval from beat to beat, suggests that the parasympathetic nervous system, the component of automatic ("autonomic") nervous system control that is associated with the relaxation response, feelings of well-being, quiet, and relaxation, is weak. It also means that the opposing sympathetic nervous sytem that regulates the "fight or flight," adrenaline-like response is allowed to be dominant. Dominance of the sympathetic over the parasympathetic system generates regularity of heart rate. Heart rate also tends to be faster, e.g., 85 beats per minutes rather than 55 or 60 beats per minute. So perfect regularity, as well as increased rate, is undesirable.What we want is irregularity of heart rate. But not irregularity that occurs chaotically with no rhyme or reason. More precisely, we want variability in heart rate. And we want variability to occur in synchrony with breathing, i.e., the respiratory cycle.The ideal response is:1) increase in heart rate with inspiration2) decrease in heart rate with expiration.Heart rate in healthy people typically varies 15-20 beats per minute within the respiratory cycle, e.g., 60 bpm at end-exhalation, 80 bpm at end-inspiration. Restoration of increased heart rate variability is associated with reduced blood pressure, reduced blood sugars (HbA1c), reduced inflammatory markers and cortisol (associated with stress), even an increase in DHEA levels. Feelings of well-being and calm also develop. Among the strategies to consider to restore heightened heart rate variability and slowed heart rate include:--Omega-3 fatty acid supplementation--Exercise--Weight loss--Deep breathing exercises--Meditation, prayer, and biofeedbackFor our Track Your Plaque purposes, we are folding in the HeartMath strategies, i.e., use of a heart rate monitor that calculates heart rate variability in the context of respiratory cycle. If you've not already done so, take a look at the two Special Reports devoted to this topic on the Track Your Plaque website. You mean weight loss is hazardous to your health? 23. September 2011 William Davis (11) In my last Heart Scan Blog post, What is this wacky thing called weight loss?, I discussed how weight loss is associated with distortions in cholesterol and blood sugar values that can be very confusing, often leading your doctor to wrongly and unnecessarily prescribe drugs--since he/she likely rarely sees weight loss.Blog reader, Donald K., posted his enlightening story: I experienced this very thing. After losing serious weight from the eliminating wheat, processed, and sugary foods (1 year in total) I lost 130 pounds. When I was nearly finished I went to see my doctor. He wanted to put me on statins. I explained to him how the data does not support application to me (no evidence of heart disease) and I got the mantra about standards of practice, etc, etc. I held my ground and decided I am much happier eating dairy, eggs, grass fed beef, wild caught fish, and as much raw foods (nuts, veggies, fruits) as my body desires to treat my health parameters. Maintaining weight, it is easy. My BMI (23 down from 40) has remained constant for a few months now. You are right: metabolic processes definitely change. I no longer have sensations of glucose fluctuations or an uncontrolled appetite. I can only imagine the improved hormone regulation and metabolic communication going on inside my body. The symptoms from obesity, all gone. Goodbye sleep apnea, hypertension, hemorrhoids, arrhythmias, gastroinestinal disruptions, smelly body, chaffing thighs, and others not mentioned. The positive effects are just as dramatic, but I don’t want to ramble on. Weight loss? What is it? Getting your life back!Brace yourself: If you are following the nutrition advice posted here and in the Track Your Plaque program, or the discussion I've initiated in Wheat Belly, then you may find yourself in the very same health predicament as Donald. Arm yourself to protect yourself against the drug-wielding ways of doctors. No, weight loss to achieve ideal weight is definitely not bad for health. But your doctor's misinterpretation of its effects can be! What is this wacky thing called "weight loss"? 20. September 2011 William Davis (41) I've discussed this before, but it has proven such an (encouragingly!) frequent issue that I thought it was worth discussing once again.What happens when you lose weight?The process of weight loss is characterized by multiple shifts in metabolic patterns that can be confusing. To the uninitiated eye, weight loss can look like a disastrous distortion in metabolism. The naive doctor on seeing your lab values, for instance, might insist you take a statin drug, a fibrate like Tricor (to reduce triglycerides or increase HDL), or simply berate you for your bad health habits--when it's actually a good thing you've accomplished.So when you lose weight, say, 30 pounds in 3 months, what have you accomplished?Energy stored as fat, especially from visceral fat stores, is mobilized into the bloodstream. It floods the bloodstream as fatty acids and triglycerides. These fatty acids and triglycerides don't occur in isolation, but interact with other particles and metabolic patterns. The resulting blood patterns include:--Increased triglycerides--An increase in triglycerides, for instance, from 90 mg/dl to 200 mg/dl in the midst of weight loss is common.--Reduced HDL--The flood of triglycerides leads to increased degradation of HDL, thus a drop. A drop in HDL from, say, 40 mg/dl to 27 mg/dl--very frightening to people--is exceptionally common.--Increased blood sugar--The flood of fatty acids and triglycerides results in insulin resistance, leading to higher blood sugars. It is not uncommon for someone with pre-diabetes to develop diabetic-range blood sugars, or a non-diabetic to show pre-diabetic blood sugars.--Increased small LDL particles--Though small LDL is highly variable during weight loss. When it does happen, it's probably from the interaction of VLDL (triglycerides) with LDL particles and the reaction that overloads LDL particles with triglycerides and conversion to small LDL particles.So why don't doctors often recognize these patterns when a patient loses weight? Because they rarely see it. Most of my colleagues are accustomed to having patients come back with weight gain, getting heavier and heavier each time. Lose weight? Impossible! So they just don't recognize weight loss effects when they see it. As followers of The Heart Scan Blog know, a frequent conversation around here is "Am I too skinny?" or "How do I stop losing weight?"The solution: Be patient. Be patient and wait about two months after a weight plateau has been achieved. That's when the numbers "settle down" and you see marked drops in triglycerides, increases in HDL, drops in blood sugar, reductions in small LDL.As with many things, it's all about timing. Why small LDL particles are the #1 cause of heart disease in the US 15. September 2011 William Davis (77) Ask your doctor: What is the #1 cause of heart disease in the US?Let's put aside smoking, since it is an eminently modifiable risk and none of those crazies read this blog anyway. What will your doctor say? Most like he or she will respond:High cholesterol or high LDL cholesterolToo much saturated fatObesityPfizer, Merck, AstraZeneca and their kind would be overjoyed to know that they can add your doctor to their eager following.I'd tell you something different. I would tell you that small LDL particles are, by far and away, the #1 cause for heart disease. I base this claim on several observations:--Having run over 10,000 lipoprotein panels (mostly NMR) over the past 15 years, it is a rare person who does not have a moderate, if not severe, excess of small LDL particles. 50%, 70%, even 90% or more small LDL particles are not rare. Over the course of a year, the only people who show no small LDL particles are slender, athletic, pre-menopausal females.--In studies in which lipoproteins have been quantified in people with coronary disease, small LDL particles dominate, just as they do in my office. Here's a 2006 review.--Small LDL is largely the province of people who consume carbohydrates, such as the American population instructed to "cut fat and eat more healthy whole grains." Conventional diet advice has therefore triggered an expllosion in small LDL particles.--When fasting triglycerides exceed 60 mg/dl, small LDL particles increase as a proportion of total LDL particles. This includes the majority of the US population. (This ignores postprandial, or after-eating, triglycerides, which also contribute to small LDL formation.)If you were to read the data, however, you might conclude that small LDL affects a minority of people. This is because in most studies small LDL categorize it as either "pattern B," meaning exceeding some arbitrary threshold of percentage of small LDL particles, versus "pattern A," meaning falling below that same arbitrary threshold.Problem: There is no consensus on what percentage of small LDL particles should mark the cutoff between pattern A vs. pattern B. In many studies, for instance, people with 50% small LDL particles are called "pattern A."If, instead, we were to set the bar lower to identify this highly atherogenic (atherosclerotic plaque-causing) particle at, say, 20-30% of total, then the number or percentage of people with "pattern B" small LDL particles would go much higher.I see this play out in my office and in the online program, Track Your Plaque, every day: At the start eating a low-fat, grain-filled diet with lots of visceral fat ("wheat belly") to start, they add back fat and cut out all wheat and limit carbohydrates. Small LDL particles plummet Even moore from Jimmy Moore 14. September 2011 William Davis (8) The ubiquitous and irrepressible Jimmy Moore posted even more commentary about the Wheat Belly phenomenon here, what he calls "The Wheat Belly Bonanza." Is low-carb really, at its core, little more than elimination of wheat? Sure, corn, rice, and sugar exert deleterious effects. But the dominant effect--by far--is the elimination of wheat. So is the low-carb movement really, at its core, a wheat-elimination movement?Food (non-wheat-containing, of course) for thought. << Older posts Newer posts >> Newer posts12345678910...121122Older posts
Wheat "debate" on CBC 11. October 2011 William Davis (29) "Many Canadians plan warm buns, stuffing and pie for their Thanksgiving meals tonight. But I'll speak with a cardiologist who thinks we have no reason to be thankful for any food that contains wheat. William Davis says our daily bread is making us fat and sick."That's the introduction to my recent interview and debate on CBC, the Canadian public radio system, aired on the Canadian Thanksgiving. Arguing the other side was Dr. Susan Whiting, an academic nutritionist. (I use the word "arguing" loosely, since she hardly argued the issues, certainly hadn't read the book, but was content to echo the conventional line that whole grains are healthy and cutting out a food group is unhealthy.) I do have to give credit to the Canadian media, including the CBC, who have been hosting some rough-and-tumble discussions about the entire wheat question despite Canada being a world exporter of wheat. I recently participated in another debate with a PhD nutrition expert from Montreal who, in response to my assertion that the genetically-altered high-yield, semi-dwarf strains have changed the basic composition of wheat, argued that the creation of the 2-foot tall semi-dwarf strain was a convenience created so that farmers could see above their fields--no kidding. I stifled my laugh. (The semi-dwarf variants were actually created to compensate for the heavy seed head that develops with vigorous nitrate fertilization that buckles 4 1/2-foot tall wheat stalk, making harvesting and threshing impossible, a process farmers call "lodging." The 2-foot tall semi-dwarf thick, stocky stalk is strong enough to resist lodging.) In short, debating the nutrition "experts" on this question has been tantamount to arguing with a school age child on the finer points of quantum physics. There has not yet been any real objection raised on the basic arguments against modern genetically-altered wheat. Modern semi-dwarf wheat is, and remains, an incredibly bad creation of the genetics laboratories of the 1970s. It has no business on the shelves of your grocery store nor on the cupboards in your home.
Carrot Cake 5. October 2011 William Davis (14) This is among my favorite recipes from the Wheat Belly book. I reproduce it here for those of you who read the Kindle or audio version and therefore didn't get the recipes.I made this most recently this past weekend. It was gone very quickly, as even the 13-year old gobbled it up.(I reduced the sour cream in this version from 8 to 6 oz to reduce cooking time. Also, note that anyone trying to avoid dairy can substitute more coconut milk, i.e., the thicker variety, in equivalent quantities.)Makes 8-10 servings Ingredients:Cake:2 cups carrots, finely grated1 cup chopped pecans1 cup coconut flour1 tablespoon ground flaxseed2 teaspoons ground cinnamon1 teaspoon allspice1 teaspoon nutmeg1 teaspoon baking powder2 tablespoons freshly grated orange peelSweetener equivalent to ½ cup sugar (e.g., 4 tablespoons Truvia)½ teaspoon sea salt4 eggs1/2 cup butter or coconut oil, melted2 teaspoons vanilla extract½ cup coconut milk6 ounces sour creamIcing:8 ounces cream cheese or Neufchâtel cheese, softened1 teaspoon lemon juice1 tablespoon Truvía or 1/8 teaspoon stevia extract powder or ¼ cup SplendaPreheat oven to 325° degrees F. Grate carrots and set aside.Combine coconut flour, flaxseed, cinnamon, nutmeg, baking powder, orange peel, sweetener, and salt in large bowl and mix by hand.Put eggs, butter or coconut oil, vanilla coconut milk, and sour cream in mixing bowl; mix by hand. Pour liquid mixture into dry pecan/coconut flour mixture and blend with power mixer until thoroughly mixed. Stir carrots and pecans in by hand with spoon. Pour mixture into greased 9- or 10-inch square cake pan.Bake for 60 minutes or until toothpick withdraws dry. Allow to cool 30 minutes.Place Neufchâtel cheese in bowl. Add lemon juice and sweetener and mix thoroughly. Spread on cake.
Why wheat makes you fat 1. October 2011 William Davis (32) How is it that a blueberry muffin or onion bagel can trigger weight gain? Why do people who exercise, soccer Moms, and other everyday people who cut their fat and eat more "healthy whole grains" get fatter and fatter? And why weight gain specifically in the abdomen, the deep visceral fat that I call a "wheat belly"?There are several fairly straightforward ways that wheat in all its varied forms--whole wheat bread, white bread, multigrain bread, sprouted bread, sourdough bread, pasta, noodles, bagels, ciabatta, pizza, etc. etc.--lead to substantial weight gain:High glucose and high insulin--This effect is not unique to wheat, but shared with other high-glycemic index foods (yes: whole wheat has a very high-glycemic index) like cornstarch and rice starch (yes, the stuff used to make gluten-free foods). The high-glycemic index means high blood glucose triggers high blood insulin. This occurs in 90- to 120-minute cycles. The high insulin that inevitably accompanies high blood sugar, over time and occurring repeatedly, induces insulin resistance in the tissues of the body. Insulin resistance causes fat accumulation, specifically in abdominal visceral fat, as well as diabetes and pre-diabetes. The more visceral fat you accumulate, the worse insulin resistance becomes; thus the vicious cycle ensues. Cycles of satiety and hunger--The 90- to 120-minute glucose/insulin cycle is concluded with a precipitous drop in blood sugar. This is the foggy, irritable, hungry hypoglycemia that occurs 2 hours after your breakfast cereal or English muffin. The hypoglyemia is remedied with another dose of carbohydrate, starting the cycle over again . . . and again, and again, and again. Gliadin proteins--The gliadin proteins unique to wheat, now increased in quantity and altered in amino acid structure from their non-genetically-altered predecessors, act as appetite stimulants. This is because gliadins are degraded to exorphins, morphine-like polypeptides that enter the brain. Exorphins can be blocked by opiate-blocking drugs like naltrexone. A drug company has filed an application with the FDA for a weight loss indication for naltrexone based on their clinical studies demonstrating 22 pounds weight loss after 6 months treatment. Overweight people given an opiate blocker reduce calorie intake 400 calories per day. But why? There's only one food that yields substantial quantities of opiate-like compounds in the bloodstream and brain: wheat gliadin. Leptin resistance--Though the data are preliminary, the lectin in wheat, wheat germ agglutinin, has the potential to block the leptin receptor. Leptin resistance is increasingly looking like a fundamental reason why people struggle to lose weight. This might explain why eliminating, say, 500 calories of wheat consumption per day yields 3500 calories of weight loss. And, as in many things wheat, the whole is greater than the sum of the parts. Despite all we know about this re-engineered thing called wheat, eliminating it yields health benefits, including weight loss, that seem to be larger than what you'd predict with knowledge of all its nasty little individual pieces.
Just who is "Real Facts 2000"? 29. September 2011 William Davis (38) This is an example of what seems to be developing over at Amazon.com, posted as a "book review": The author has no credentials, no credibility, just a small cult of terribly misinformed followers. Don't be fooled by the high volume screech against wheat and grains. Allegations of "secret ingredients in wheat" to make you eat more, or comparisons to cigerettes. Seriously?! For over 8000 years wheat has sustained and grown human kind, oh and it tastes good when mixed with a little water and yeast. Every nutritionist and serious medical professional will tell you that bread is the most economical and safe source of essential nutrients. In fact, bread is handed out in natural disasters because it sustains life without food safety issues or requiring refrigeration. And now, suddenly it will kill you. Comical! This book is such a bone headed, misinformed way to just scare people into not eating. As for secret ingredients, humm, apparently the author is ignorant of the food laws that regulate everything that goes into food and on food labels. Unlike some enforcement agencies, the FDA has some serious teeth behind its enforcement. As for frankenwheat, again seriously?! Wheat, due to its ubiquitous presence in the world is treated as sacrosant from any GMO research or development. If you need real, science based information on healthy eating, check out [...] and leave this book and its cult in the compound.If you recognize the wording and tone, you will readily recognize the footprints of the Wheat Lobby here. "Terribly misinformed followers"? . . . Hmmm. "Food laws"? I didn't realize that eating more "healthy whole grains" was a . . . law?Make no mistake: There are people and organizations who have a heavy stake in your continued consumption of the equivalent of 300 loaves of bread per year. There are people and organizations (read: pharmaceutical industry) who have a big stake on the "payoff" of your continued consumption of "healthy whole grains." This is not a book review; this is part of a concerted, organized campaign to discredit a message that needs to be heard. Anybody from the media listening?
Almonds are the new wheat 29. September 2011 William Davis (31) Once you eliminate this genetically-altered Frankengrain called modern wheat, the diet should center around vegetables, nuts, healthy oils like olive and coconut, fish, meats, cheese, olives, avocados and other real whole foods. This is, in fact, the diet that I have advocated in my heart disease prevention practice, as well as my online program for prevention and reversal of heart disease. But what if you'd like a piece of cheesecake or a nice slice of dessert bread---but you don't want to gain two pounds, spend 48 hours in the bathroom suffering with diarrhea and cramps, 3 weeks of joint pains and leg swelling, wade through mental "fog," anxiety, and rage just because you had that momentary indulgence---as you would with wheat? That's why I've been focusing on recipes that allow you to have something familiar, e.g., chocolate coconut bread or biscotti, but using ingredients that will not generate the metabolic contortions triggered by wheat. On perusing these recipes, you will notice that there are recurring ingredient themes. Many of the same ingredients pop up time and again. Among the most frequent, versatile, user-friendly, and tasty: Almonds. You can use almonds as ground whole almonds, ground blanched almonds for a finer texture, ground roasted almonds, almond butter (though, for maximum health benefits, I prefer the ground whole almonds). Ground almonds allow you to recreate muffins, breads, scones, pizza crust, pie crust, biscotti, and cookies with health benefits that exceed that of whole wheat---but with none of the downside: no weight gain, no high blood sugar, no triggering of small LDL particles (#1 cause of heart disease in the U.S.), no accumulation of visceral fat, no appetite stimulation. In short, you just have your chocolate almond biscotti or mocha cupcake and enjoy it, no health price to pay. So I call almonds the new wheat, except better.
Being regular is dangerous to your health 25. September 2011 William Davis (21) No, I'm not referring to your daily morning ritual in the bathroom. I'm talking about heart rate.Counterintuitively, a perfectly regular heart rate is a marker of poor health. People with perfect regularity of heart rate have more heart attacks, for instance.Regularity of heart rate occurs more commonly in people with hypertension and other metabolic derangements, and it signals increased risk for both heart attack and death. A perfectly regular heart rate, i.e., no variation in the time interval from beat to beat, suggests that the parasympathetic nervous system, the component of automatic ("autonomic") nervous system control that is associated with the relaxation response, feelings of well-being, quiet, and relaxation, is weak. It also means that the opposing sympathetic nervous sytem that regulates the "fight or flight," adrenaline-like response is allowed to be dominant. Dominance of the sympathetic over the parasympathetic system generates regularity of heart rate. Heart rate also tends to be faster, e.g., 85 beats per minutes rather than 55 or 60 beats per minute. So perfect regularity, as well as increased rate, is undesirable.What we want is irregularity of heart rate. But not irregularity that occurs chaotically with no rhyme or reason. More precisely, we want variability in heart rate. And we want variability to occur in synchrony with breathing, i.e., the respiratory cycle.The ideal response is:1) increase in heart rate with inspiration2) decrease in heart rate with expiration.Heart rate in healthy people typically varies 15-20 beats per minute within the respiratory cycle, e.g., 60 bpm at end-exhalation, 80 bpm at end-inspiration. Restoration of increased heart rate variability is associated with reduced blood pressure, reduced blood sugars (HbA1c), reduced inflammatory markers and cortisol (associated with stress), even an increase in DHEA levels. Feelings of well-being and calm also develop. Among the strategies to consider to restore heightened heart rate variability and slowed heart rate include:--Omega-3 fatty acid supplementation--Exercise--Weight loss--Deep breathing exercises--Meditation, prayer, and biofeedbackFor our Track Your Plaque purposes, we are folding in the HeartMath strategies, i.e., use of a heart rate monitor that calculates heart rate variability in the context of respiratory cycle. If you've not already done so, take a look at the two Special Reports devoted to this topic on the Track Your Plaque website.
You mean weight loss is hazardous to your health? 23. September 2011 William Davis (11) In my last Heart Scan Blog post, What is this wacky thing called weight loss?, I discussed how weight loss is associated with distortions in cholesterol and blood sugar values that can be very confusing, often leading your doctor to wrongly and unnecessarily prescribe drugs--since he/she likely rarely sees weight loss.Blog reader, Donald K., posted his enlightening story: I experienced this very thing. After losing serious weight from the eliminating wheat, processed, and sugary foods (1 year in total) I lost 130 pounds. When I was nearly finished I went to see my doctor. He wanted to put me on statins. I explained to him how the data does not support application to me (no evidence of heart disease) and I got the mantra about standards of practice, etc, etc. I held my ground and decided I am much happier eating dairy, eggs, grass fed beef, wild caught fish, and as much raw foods (nuts, veggies, fruits) as my body desires to treat my health parameters. Maintaining weight, it is easy. My BMI (23 down from 40) has remained constant for a few months now. You are right: metabolic processes definitely change. I no longer have sensations of glucose fluctuations or an uncontrolled appetite. I can only imagine the improved hormone regulation and metabolic communication going on inside my body. The symptoms from obesity, all gone. Goodbye sleep apnea, hypertension, hemorrhoids, arrhythmias, gastroinestinal disruptions, smelly body, chaffing thighs, and others not mentioned. The positive effects are just as dramatic, but I don’t want to ramble on. Weight loss? What is it? Getting your life back!Brace yourself: If you are following the nutrition advice posted here and in the Track Your Plaque program, or the discussion I've initiated in Wheat Belly, then you may find yourself in the very same health predicament as Donald. Arm yourself to protect yourself against the drug-wielding ways of doctors. No, weight loss to achieve ideal weight is definitely not bad for health. But your doctor's misinterpretation of its effects can be!
What is this wacky thing called "weight loss"? 20. September 2011 William Davis (41) I've discussed this before, but it has proven such an (encouragingly!) frequent issue that I thought it was worth discussing once again.What happens when you lose weight?The process of weight loss is characterized by multiple shifts in metabolic patterns that can be confusing. To the uninitiated eye, weight loss can look like a disastrous distortion in metabolism. The naive doctor on seeing your lab values, for instance, might insist you take a statin drug, a fibrate like Tricor (to reduce triglycerides or increase HDL), or simply berate you for your bad health habits--when it's actually a good thing you've accomplished.So when you lose weight, say, 30 pounds in 3 months, what have you accomplished?Energy stored as fat, especially from visceral fat stores, is mobilized into the bloodstream. It floods the bloodstream as fatty acids and triglycerides. These fatty acids and triglycerides don't occur in isolation, but interact with other particles and metabolic patterns. The resulting blood patterns include:--Increased triglycerides--An increase in triglycerides, for instance, from 90 mg/dl to 200 mg/dl in the midst of weight loss is common.--Reduced HDL--The flood of triglycerides leads to increased degradation of HDL, thus a drop. A drop in HDL from, say, 40 mg/dl to 27 mg/dl--very frightening to people--is exceptionally common.--Increased blood sugar--The flood of fatty acids and triglycerides results in insulin resistance, leading to higher blood sugars. It is not uncommon for someone with pre-diabetes to develop diabetic-range blood sugars, or a non-diabetic to show pre-diabetic blood sugars.--Increased small LDL particles--Though small LDL is highly variable during weight loss. When it does happen, it's probably from the interaction of VLDL (triglycerides) with LDL particles and the reaction that overloads LDL particles with triglycerides and conversion to small LDL particles.So why don't doctors often recognize these patterns when a patient loses weight? Because they rarely see it. Most of my colleagues are accustomed to having patients come back with weight gain, getting heavier and heavier each time. Lose weight? Impossible! So they just don't recognize weight loss effects when they see it. As followers of The Heart Scan Blog know, a frequent conversation around here is "Am I too skinny?" or "How do I stop losing weight?"The solution: Be patient. Be patient and wait about two months after a weight plateau has been achieved. That's when the numbers "settle down" and you see marked drops in triglycerides, increases in HDL, drops in blood sugar, reductions in small LDL.As with many things, it's all about timing.
Why small LDL particles are the #1 cause of heart disease in the US 15. September 2011 William Davis (77) Ask your doctor: What is the #1 cause of heart disease in the US?Let's put aside smoking, since it is an eminently modifiable risk and none of those crazies read this blog anyway. What will your doctor say? Most like he or she will respond:High cholesterol or high LDL cholesterolToo much saturated fatObesityPfizer, Merck, AstraZeneca and their kind would be overjoyed to know that they can add your doctor to their eager following.I'd tell you something different. I would tell you that small LDL particles are, by far and away, the #1 cause for heart disease. I base this claim on several observations:--Having run over 10,000 lipoprotein panels (mostly NMR) over the past 15 years, it is a rare person who does not have a moderate, if not severe, excess of small LDL particles. 50%, 70%, even 90% or more small LDL particles are not rare. Over the course of a year, the only people who show no small LDL particles are slender, athletic, pre-menopausal females.--In studies in which lipoproteins have been quantified in people with coronary disease, small LDL particles dominate, just as they do in my office. Here's a 2006 review.--Small LDL is largely the province of people who consume carbohydrates, such as the American population instructed to "cut fat and eat more healthy whole grains." Conventional diet advice has therefore triggered an expllosion in small LDL particles.--When fasting triglycerides exceed 60 mg/dl, small LDL particles increase as a proportion of total LDL particles. This includes the majority of the US population. (This ignores postprandial, or after-eating, triglycerides, which also contribute to small LDL formation.)If you were to read the data, however, you might conclude that small LDL affects a minority of people. This is because in most studies small LDL categorize it as either "pattern B," meaning exceeding some arbitrary threshold of percentage of small LDL particles, versus "pattern A," meaning falling below that same arbitrary threshold.Problem: There is no consensus on what percentage of small LDL particles should mark the cutoff between pattern A vs. pattern B. In many studies, for instance, people with 50% small LDL particles are called "pattern A."If, instead, we were to set the bar lower to identify this highly atherogenic (atherosclerotic plaque-causing) particle at, say, 20-30% of total, then the number or percentage of people with "pattern B" small LDL particles would go much higher.I see this play out in my office and in the online program, Track Your Plaque, every day: At the start eating a low-fat, grain-filled diet with lots of visceral fat ("wheat belly") to start, they add back fat and cut out all wheat and limit carbohydrates. Small LDL particles plummet
Even moore from Jimmy Moore 14. September 2011 William Davis (8) The ubiquitous and irrepressible Jimmy Moore posted even more commentary about the Wheat Belly phenomenon here, what he calls "The Wheat Belly Bonanza." Is low-carb really, at its core, little more than elimination of wheat? Sure, corn, rice, and sugar exert deleterious effects. But the dominant effect--by far--is the elimination of wheat. So is the low-carb movement really, at its core, a wheat-elimination movement?Food (non-wheat-containing, of course) for thought.
