One bite or many mouthfuls 6. januára 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. januára 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. This is what the aortic valve should look like on a CT heart scan--you shouldn't see it at all. The first man with the calcified valve will unfortunately require a new prosthetic aortic valve sometime in his future. This is usually determined with the help of an ultrasound, or echocardiogram, a better test for assessment of the aortic valve (though useless for detection of coronary plaque).It's my suspicion that chronic and longstanding deficiency of vitamin D is among the factors that contribute to the abnormal deposition of calcium on the aortic valve. We desperately need more data on this. Nonetheless, perhaps this adds yet another reason to 1)get a CT heart scan, and 2) bring your vitamin D blood level to normal. (We aim for 50 ng/ml year round.)
Fish oil and the perverse logic of hospitals 4. januára 2007 William Davis (6) Hospitals are now starting to carry prescription fish oil, known as Omacor, on their formularies. It's used by some thoracic surgeons after bypass surgery, since fish oil has been shown to reduce the likelihood of atrial fibrillation (a common rhythm after heart surgery).Why now? The data confirming the benefits of fish oil on atrial fibrillation has been available for several years. It's now available in hospitals because it's FDA-approved. In other words, when fish oil was just a supplement, it was not available in most hospitals. Whenever I've tried to get fish oil for my patients while in hospital, you'd think I was trying to smuggle Osama Bin Laden into the place. The resistance was incredible. Now that FDA-approved Omacor is available, costing $130 dollars per month for two capsules, $195 for the three capsule per day dose for after surgery, all of a sudden it becomes available. Why would this irrational state of affairs occur in hospitals? Several reasons, most of which revolve around the great suspicion my colleagues have towards nutritional supplements. In addition, there's the litigation risk: If something has been approved by the FDA, their stamp of endorsement provides some layer of legal protection.However, I regard those as pretty weak reasons. I am, indeed, grateful that fish oil is gaining a wider audience. But I think it's absurd that it requires a prescription to get it in many hospitals. Imagine, as the drug companies would love, vitamin C became a prescription agent. Instead of $3, it would cost far more. Does that make it better, safer, more effective? Of course, no drug sales representative is promoting the nutritional supplement fish oil to physicians nor to hospitals. I now see people adding the extraordinary expense of prescription fish oil to their presription bills. In my view, it's unnecessary, irrational, and driven more by politics and greed than actual need. Take a look at the website for Omacor (www.omacorrx.com). Among the claims:"OMACOR is the only omega-3 that, along with diet, has been proven and approved to dramatically reduce very high triglycerides..." This is a bald lie. Dozens of studies have used nutritional supplement fish oil and shown spectacular triglyceride-reducing effects.Their argument against fish oil supplements:"Dietary supplements are not FDA-approved for the treatment of any specific disease or medical condition. Get the Facts: nonprescription, dietary supplement omega-3 is not a substitute for prescription OMACOR." Does that make any sense to you? Should you buy a GM car because only GM makes genuine GM cars? This is the silly logic being offered by these people to justify their ridiculous pricing. How about: "The unique manufacturing process for OMACOR helps to eliminate worries about mercury and other pollution from the environment." Funny...mercury in fish tends to be sequestered in the meat, not the oil. Independent reports by both Consumer Reports and Consumer Lab found no mercury, nor PCB's, in nutritional supplement fish oil. But just suggesting a difference without proving it may be enough to scare some people. Just because something is used by a hospital does not make it better. The adoption of fish oil is hospitals is a good thing. Too bad it has to add to already bloated health care costs to enrich some drug manufacturer.
Repent for past sins 2. januára 2007 William Davis (0) If the food temptations of the holidays got the best of you, and you're now 5, 10, 15 lbs or more over your pre-holiday weight (our record is 18lbs!), then it's time for serious action. One easy method to regain the control you may have lost is to pick some period, say, 3 days. During those three days, eat nothing but vegetables--no breads, meats, dairy products, certainly no cookies, cakes, pasta, etc., not even fruit. Follow this routine and weight drops rapidly. Vegetables are wonderful but sometimes boring, so use healthy condiments to spice them up: mustards (hot, brown, yellow, horseradish); healthy salad dressings, which are olive or canola oil-based; salsas, a fabulous garnish with no nutritional downside whatsoever; pesto; tapenades; horseradish added to other condiments or even by itself (wasabi).Of course, fasting in one of its several variations is another rapid method to regain control. My favorite is to use soy milk in a modified fast, usually 4-6 glasses of a low-fat, low-sugar soy milk per day, along with plenty of water. (Please refer to the precautions detailed in the recent Track Your Plaque Special Report, Fasting: Fast Track to Control Plaque , particularly if you fast 5 days or longer or take blood pressure or diabetic medication.) Of course, yo-yoing your weight--up during the holidays, down after their conclusion--is not good for you. It does raise the likelihood of diabetes, not to mention cultivate the patterns that contribute to coronary plaque growth, especially small LDL. But if temptation got out of control and you need to regain lost ground, these two strategies work fabulously well for most people. If you've gained, say, 10 lbs during the holidays, but simply resume your usual habits, chances are you won't lose the weight. Year after year, this can add up to an enormous weight gain. The time to act is now. It's easier to lose the 10 lbs of weight you gained recently, rather than the 50 lbs you've stacked up over the past 5 years.
Wheat-free 2007 1. januára 2007 William Davis (4) Long ago, most of us made the change of reducing saturated fat in our diet. Few people now rely on butter (despite the idiotic butter vs. margarine controversy), full-fat dairy products, fried foods, and greasy meats. That's a healthy change, since saturated fat has conclusively been tied to various cancers, high blood pressure, rise in LDL, and is calorie-dense. But if there were just one change you were to make beyond a reduction in saturated fat, a change that would translate into dramatic health benefits, it would be a drastic reduction, even elimination, of wheat products.People do indeed eat enormous quantities of wheat flour-containing products. U.S. per capita consumption of wheat flour was 110 pounds in the early 1970s, and rose to 141 pounds in 1991. It's even higher now. 20% or more of most people's caloric intake every day is provided by wheat flour products. Wheat containing foods are tasty and convenient. Witness the popularity of bagel shops, the goodie counter at Starbuck's, the proliferation of crackers, breads, and breakfast cereals at the grocery store. Patients are horrified when I suggest that they find a substitute for the sandwiches they eat every day. Even Mom said they were okay! You're unlikely to hear much about this from the popular press. The wheat industry is enormous and exerts extraordinary clout, just like the drug industry. Texas alone farms 6 million acres of wheat, yielding over $2 billion for the state's economy. The "wheat chain" is complex and far-reaching: growers, processors, food manufacturers, the transportation industry, retailers, chemical producers, and on and on. Wheat futures are traded on the Chicago Board of Trade. Wheat is a major export industry for the U.S. Of course, these are not evil people, intent on corrupting your health. In fact, most of them are probably working under the perception that they are raising a healthy product. The point is that the notion that wheat is healthy is deeply entrenched in the minds and economy of the U.S. Don't expect to hear unbiased commentary on the health effects of wheat products from most media sources. What can you expect if you sharply reduce or eliminate wheat? The majority of people:--Feel like a cloud has been lifted from their thinking. --Don't experience the afternoon blah or tired feeling after lunch.--Lose weight, sometimes substantial quantities.--Raise HDL.--Reduce small LDL.--Reduce triglycerides, particularly if they start >100 mg/dl.--Reduce blood sugar. The reduction in small LDL can be especially impressive. For most people, reducing or eliminating wheat is a sacrifice, a major change in food choices and even a loss of convenience. But the health benefits for most people can be dramatic.
Is vitamin D a "vitamin"? 29. decembra 2006 William Davis (5) Vitamins are crucial participants in the body's reactions and are obtainable from food. Vitamin C, for example, comes from citrus fruits and vegetables. Vitamin K comes from green vegetables. The B vitamins are found in meats, soy, dairy products, and grains. Vitamin A comes from carrots, squash, and other orange and green colored vegetables.How about vitamin D? What foods contain vitamin D? The list includes:Food International Units(IU) vitamin D per serving Cod liver oil, 1 Tablespoon 1,360Salmon, cooked, 3½ ounces 360Mackerel, cooked, 3½ ounces 345Tuna fish, canned in oil, 3 ounces 200Sardines, canned in oil, drained, 1¾ ounces 250Milk, nonfat, reduced fat, and whole, vitamin D fortified, 1 cup 98Margarine, fortified, 1 Tablespoon 60Pudding, prepared from mix and made with vitamin D fortified milk, ½ cup 50Cheese, Swiss, 1 ounce 12Ready-to-eat cereals fortified with 10% of the DV for vitamin D, ¾ cup to 1 cup servings (servings vary according to the brand) 40Egg, 1 whole (vitamin D is found in egg yolk) 20Liver, beef, cooked, 3½ ounces 15(Modified from the Office of Dietary Supplements, National Institutes of Health)You'll note that the only naturally-occurring food sources of vitamin D are the modest quantities in fish, egg yolks, and liver. All the other vitamin D-containing foods like cereal, milk, and other dairy products have vitamin D only because humans add it. It takes me (personally) 6000 units of vitamin D per day to bring my blood level to an acceptable 50 ng/ml. To obtain this from eating salmon, I would have to eat 58 ounces, or 3 1/2 pounds of salmon--every day. Or, I could eat 30 cans of tuna fish. If I didn't want to eat loads of fish every day, I could drink 60 glasses of milk every day. After I recovered from the diarrhea, my vitamin D might be adequate, provided the milk indeed contained the amount stated on the label (which it often does not when scrutinized by the USDA). If vitamin D is a vitamin, how are humans supposed to get sufficient quantities? I don't know anybody who can eat 3 1/2 lbs of salmon per day, nor drink 60 glasses of milk per day. But aren't vitamins supposed to come from food?The problem is that vitamin D is 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. decembra 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. decembra 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. decembra 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. decembra 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.
