One bite or many mouthfuls 6. January 2007 William Davis (0) A reader brought this beautiful series of food photos to my attention:http://www.wisegeek.com/what-does-200-calories-look-like.htmIt's simply a graphic display of what 200 calories of various foods look like. You'll note that vegetables and fruits permit large servings to yield 200 calories. Processed foods, on the other hand, require very little to tally up the same calorie load. In particularly, look how little in the way of wheat products are required to match that amount.
Heart scan curiosities #4 5. January 2007 William Davis (2) Here's an interesting example of a 63-year old man with a heart scan score of 112. However, his aortic valve was also severely calcified (loaded with calcium). In other words, the normally flexible and mobile "leaflets" of the aortic valve were coated with calcium and other tissues that interfere with its free motion. The aortic valve is the starburst white in the center of the heart. All posts by william-davis Toggle navigation Home Blog Home Archive Join Now Log in America: The world’s diet laboratory 23. October 2007 William Davis (14) Low-fat, low-carb, high-protein, Pritikin, Ornish, Atkins, South Beach, Sonoma, Sugar-Busters, Weight Watchers, vegetarian . . . Have Americans tried them all?We’ve witnessed the relative success of diet habits in selected regions world-wide: the longevity of the Japanese on a spare soy and fish-based diet; the reduced heart disease incidence of the French despite an indulgent food-centered culture; the extreme heart disease-free lives of the Cretan Greeks. Contrast this with the startling failure of the American diet experiment: We’re all (speaking for the collective whole) fat, diabetic, and miserably mired in the diseases of obesity. We’ve experimented with every possible iteration of diet from grapefruit or cabbage only, to calorie deprivation (a al Weight Watchers), to restricting this or that element of diet. The “official” organizations have made their contributions, as well: the American Heart Association’s Therapeutic Lifestyle Changes (formerly Step I and II diets), a program eerily similar to what Americans are already eating and resulting in failure; the American Diabetes Association diet, incomprehensibly embracing carbohydrates when they are the root of the nutrition-habit-gone-wrong that caused the disease in the first place; the USDA and their Food Pyramid, encompassing a design that contains the germ of wisdom but is so heavily overweighted in grains that it is a sure-fire way to increase weight and heart disease were you to follow their recommendations. What have we learned from our grand experiment, our nationwide misadventure in nutrition? I believe that we’ve learned how not to eat: Processed snack foods, meals delivered in a fast-food setting with the offer to “super-size” your order, make-believe food ingested in your car eaten for the sake of staving off the inevitable hunger pangs. Few would argue that these are certain paths to obesity and poor health. Certainly, if we’ve learned how not to eat, can we extrapolate just how to eat? And not just for weight loss, since most diets focus just on that, but on health, particularly heart health?Iis not really a vitamin, it's a hormone. If your thyroid hormone level was low, you'd gain 20, 30, or more pounds in weight, your blood pressure would skyrocket, you'd lose your hair, become constipated, develop blood clots, be terribly fatigued. In other words, you'd suffer profound changes. Likewise, if thyroid hormone levels are corrected by giving you thyroid hormone, you'd experience profound correction of these phenomena. That's what I'm seeing with vitamin D: restoration of this hormone to normal blood levels (25-OH-vitamin D3 50 ng/ml) yields profound changes in the body. If there's one thing that I've come across lately that packs extraordinary potential to help us in reducing heart scan scores, it's the vitamin--sorry, the hormone--cholecalciferol, or D3. Heart scan curiosities 3 28. December 2006 William Davis (0) Note the shape of the chest in this 64-year old man. The front of his chest (upper portion of scan) is concave. In other words, if you were looking at this man (shirtless, of course) face to face, his chest would bow inward, rather than the usual outward configuration. The official name for this is "pectus excavatum". Compare this to the normal chest in the second image, in which the chest is convex. Face to face, the chest would bow slightly outward. What does it matter? The pectus excavatum in and of itself has no importance, just a curiousity. (I personally find this surprising, given the fact that the heart actually appears squashed by the sternum, or chest wall.) However, it is commonly associated with a "floppy" mitral valve (also called mitral valve prolapse), a common congenital disorder of the mitral valve often accompanied by a slender build, loose joints, and even a nervous disposition. Occasionally, in its more severe forms, the aorta is also enlarged. (This man's aorta is not enlarged.)So, while we can't actually visualize the mitral valve by a CT heart scan, we can surmise that he likely has a floppy mitral valve, is slender, is probably a nervous sort, and has long limbs with loose joints. He probably required braces as a child, since many people have a phenemenon of "crowded teeth". The roof of his mouth, or hard palate, probably unusually high up in the mouth. He probably has a "weak chin", meaning a less prominent protuberance of his chin. His fingers and toes are likely unusually long and slender. It could mean that some attention and exploration of how floppy his mitral valve might be could be useful, e.g., an ultrasound or echocardiogram. He might even require oral antibiotics at the time of any oral or some gastrointestinal procedures, since floppy valve are more susceptible to blood infections when potentially "dirty" orifices are instrumented. All that from a heart scan! Gratitude 24. December 2006 William Davis (2) The holidays and the end of the year may be a good time to reflect on how grateful we should be for having the freedom to discuss the ideas we share on this Blog, the Track Your Plaque website, online and offline. Although I rant and rave against the status quo in heart disease, the shameful profiteering of my colleagues and hospitals, the cut-throat marketing practices of drug and device manufacturers, I am truly grateful that, in the U.S., I have the extraordinary freedom to say these things. You have the freedom to agree or disagree and none of us pays a price for truth.I've been reflecting myself a great deal on this idea of happiness and gratitude being a critical component of coronary plaque regression and dropping your heart scan score. (See The Heart Scan Blog from earlier this week.) The more I think about this, the more I think that it is indeed true: Harboring anger and resentment, regrets, irritability, all those petty emotions that most of us know are not good for us, erode our chances for success in dropping your heart scan score. We could rationalize it this way: Anger and other negative emotions are adrenaline-driven states, also characterized by activation of the "sympathetic" nervous system. (Despite its name, the sympathetic system is not sympathetic, as in compassionate; its the "fight-or-flight" activator that accelerates heart rate and blood pressure.) Happiness, contentment, and gratitude are "parasympathetic" states characterized by slower heart rates, deeper respiration, greater variation in beat-to-beat heart rates (a powerful predictor for health and the basis for the HeartMath program of Lew Childre), lower blood pressure, and even a subtle change in brain waves. In other words, happiness is not just a mental and emotional state, it is a constellation of physical phenomena. Even though I pick on Dr. Dean Ornish for his stubborn adherence to the outdated low-fat mantra, I do agree with him on the value of happiness. His book, Love and Survival, articulates this concept. Ornish has even said on several occasions that it wasn't the diet that was most important but the connection and warmth that was created by the comraderie created by participation in the Ornish Program group sessions. I am personally grateful that the concepts I promote are gaining a following and that I can say so without fear of prosecution. I am grateful that Track Your Plaque followers are not just sharing our concepts, but obtaining genuine and powerful health advice that will help keep them home and healthy, away from hospitals, procedures, and the dangers of heart disease. I hope you share in my gratitude and are thankful for all the truly wonderful things that surround us. I wish you all a wonderful holiday and long, healthy life filled with gratitude. A Track Your Plaque failure 23. December 2006 William Davis (0) We recently had a man suffer a heart attack after beginning the program. Let me tell you the details.Jerry's heart scan score 781, age 53. Multiple lipoprotein abnormalities: HDL 32 mg/dl, triglycerides 279 mg/dl, nearly all of his LDL was in small particles with an "effective" LDL (LDL particle number), and very high IDL. So Jerry added fish oil 6000 mg per day, niacin, and vitamin D to the statin drug prescribed by his primary physician. Jerry added oat bran, ground flaxseed, and tried to eat fish at least once per week. However, Jerry continued to smoke. He'd smoked for 40 years (!), up to 2 packs per day, and just reasoned that it was too late to quit. He also continued to indulge in the packaged, processed foods that were part of his convenience story business. Jerry's stress test was normal--no chest pain, normal EKG, normal images of blood flow, though he was somewhat breathless, likely from his lung disease from smoking. Two months into his program, he abruptly experienced severe crushing pain in his chest. Because he was traveling, he ended up in a small local hospital. A failed angioplasty led to urgent coronary bypass surgery. Jerry's alive. Now he's a non-smoker. He's got the pursed lips and peculiar breathing pattern that smokers get, but he's breathing. Lesson: In the face of the most powerful program for heart disease known, it can still be overpowered by Twinkies, Hoho's, pretzels, chips--and cigarettes. The new year is approaching. Be grateful for another year of healthy life and commit to a new year of even greater health. If you're a smoker, there's no choice: you've got to quit. Are you more like a dog or a rabbit? 20. December 2006 William Davis (11) Dr. William Roberts, editor of the American Journal of Cardiology and cardiovascular pathologist, is a perennial source of clever ideas on heart disease.In a recent editorial, Dr. Roberts comments:"Because humans get atherosclerosis, and atherosclerosis is a disease only of herbivorers, humans also must be herbivores. Most humans, of course, eat flesh, but that act does not make us carnivores. Carnivores and herbivores have different characteristics. (1) The teeth of carnivores are sharp; those of herbivores, flat (humans have some sharp teeth but most are flat for grinding the fruits, vegetables, and grains we are built to eat). (2) The intestinal tract of carnivores is short (about 3 times body length); that of herbivores, long (about 12 times body length). (Since I am 6 feet tall my intestinal tract should be about 60 feet long. As a consequence, if I eat bovine muscle [steak], it could take 5 days to course through those 20 yards.) (3) Body cooling for carnivores is done by panting because they have no ability to seat; although herbivores also can pant, they cool their bodies mainly by sweating. (4) Drinking fluids is by lapping them for the carnivore; it is by sipping them for the herbivore. (5) Vitamin C is made by the carnivore's own body; herbivores obtain their ascorbic acid only from their diet. Thus, although most human beings think we are carnivores or at least conduct their lives as if we were, basically humans are herbivores. If we could decrease our flesh intake to as few as 5 to 7 meals a week our health would improve substantially." You can always count on Dr. Bill Roberts to come up with some clever observations. I think he's right. Some of the most unhealthy people I've known have been serious meat eaters. Most of the vegetarians have been among the healthiest. (I say most because if a vegetarian still indulges in plenty of junk foods like chips, crackers, breakfast cereals, breads, etc., then they can be every bit as unhealthy as a meat eater.) Should you become a vegetarian to gain control over coronary plaque and other aspects of health? I don't believe you have to. However, modern livestock raising practices have substantially modified the composition of meats. A steak in 2006, for instance, is not the same thing as a steak in 1896. The saturated and monounsaturated fat content are different, the pattern of fat "marbling" is different, the lean protein content is different. Meat is less healthy today than 100 years ago. Take a lesson from Dr. Roberts' tongue-in-cheek but nonetheless provocative thoughts. Pardon me while I chew on some carrots. << Older posts Newer posts >> Newer posts12...949596979899100101102...121122Older posts
