The meat intake was probably from smaller animals. On the other hand, mammoths were probably similar to elephants in being non-ruminants having lower concentrations of saturated fat.

Did you read something > indicating that people on his diet had the wrong type of LDL > cholesterol? end up with lower LDL particle size leading towards faster cardiovascular disease progression. Trans-fats also lower particle size. So Ornish by cutting fat generally got the benefit of LDL particle size increases from lowering trans-fat consumption while getting the negative of lowering LDL particle size by cutting other healthy fats. There was a general win there but not because of the low-fat diet. Cutting trans fats AND maintaining fat consumption would have generated much better results. (I find that polyunsaturated fats - PUFAs - are best avoided and that mono and saturated fats are preferred, but thats another discussion.) Effect of a low-carbohydrate, ketogenic diet program compared to a low-fat diet on fasting lipoprotein subclasses. Westman EC, Yancy WS Jr, Olsen MK, Dudley T, Guyton JR. Department of Medicine, Duke University Medical Center, Durham, NC 27705, USA. ewestman[at]duke.edu BACKGROUND: Low-carbohydrate, ketogenic diets (LCKD) are effective for weight loss, but concerns remain regarding cardiovascular risk. The purpose of this study was to determine the effect of an LCKD program on serum lipoprotein subclasses. METHODS: This was a randomized, two-arm clinical trial in an outpatient research clinic involving overweight, hyperlipidemic community volunteers motivated to lose weight. Subjects were randomized to either an LCKD (n = 59) and nutritional supplementation (including fish, borage and flaxseed oil), or a low-fat, reduced-calorie diet (LFD, n = 60). The main outcomes were fasting serum lipoprotein subclasses determined by nuclear magnetic resonance analysis. RESULTS: The mean age of subjects was 44.9 years, the mean BMI was 34.4 kg/m(2), and 76% were women. Comparing baseline to 6 months, the LCKD group had significant changes in large VLDL (-78%), medium VLDL (-60%), small VLDL (-57%), LDL particle size (+2%), large LDL (+54%), medium LDL (-42%), small LDL (-78%), HDL particle size (+5%), large HDL (+21%), and LDL particle concentration (-11%). Compared with the LFD group, the LCKD group had greater reductions in medium VLDL (p = 0.01), small VLDL (p = 0.01) and medium LDL (p = 0.02), and greater increases in VLDL particle size (p = 0.01), large LDL (p = 0.004), and HDL particle size (p = 0.05). CONCLUSIONS: The LCKD with nutritional supplementation led to beneficial changes in serum lipid subclasses during weight loss. While the LCKD did not lower total LDL cholesterol, it did result in a shift from small, dense LDL to large, buoyant LDL, which could lower cardiovascular disease risk. Low-density-lipoprotein subclasses and response to a low-fat diet in healthy men. Krauss RM, Dreon DM. Donner Laboratory, Lawrence Berkeley Laboratory, University of California, Berkeley 94720, USA. Lipid and lipoprotein responses to reduced dietary fat intake were investigated in relation to differences in distribution of low-density-lipoprotein (LDL) subclasses among 105 healthy men consuming high-fat (46% fat) and low-fat (24% fat) diets in random order for 6 wk each. With high-fat diets, 87 subjects had predominantly large, buoyant LDL (pattern A), whereas the remainder had primarily smaller, denser LDL (pattern B). With low-fat diets, 36 men changed from pattern A to B. Compared with the 51 men with pattern A with both diets (stable A group), men in the stable B group (n = 18) had significantly greater reductions in plasma LDL cholesterol, apolipoprotein B, and mass of mid-sized (LDL II) and small (LDL III) LDL subfractions. In both the stable A and change groups, there was a shift in LDL particle mass from larger, lipid-enriched (LDL I and II) to smaller, lipid-depleted (LDL III and IV) subfractions, suggestive of change in LDL composition with minimal change in particle number, and consistent with the observation of reduced plasma LDL cholesterol without reduced apolipoprotein B. Stable B subjects had significantly greater increases in the largest very-low-density-lipoprotein subfraction with the low-fat diet than the stable A group, and also had greater decreases in the high-density-lipoprotein (HDL) subclass HDL3 but smaller reductions in HDL2. Genetic and environmental factors influencing LDL subclass distributions thus may also contribute substantially to interindividual variation in plasma lipoprotein response to a low-fat diet.

Perhaps now but I've never read where he factored that into his "lowfat" vegetarian style diet as the source of the benefit he obtained. I'm still convinced from the mounds of research abstracts I've read over the years that ornish was lucky simply because he cut trans-fats and that greater benefits would have come from merely eliminating trans-fats, not cutting fat or meat (and getting fat from other than PUFA sources). - quote - > > A better look at the research has been done by Gary Taubes in "Good

For one third of the people on his recommended low fat diet, their LDL will decrease in size, a very bad thing. The only upside to his low fat diet was the decrease in trans-fats which was a side effect that he was clueless about. A better look at the research has been done by Gary Taubes in "Good Calories Bad Calories". Dean Ornish doesn't strike me as a "low carb advocate" as he was not too fond of meat. Perhaps he has changed his stripes in the past year or two. Saturated fat has it's place in good health. I take the paleo diet generally as my guide in these matters and when modern "experts" deviate far from paleo, they are moving in an unhealthy direction.

| NewsTarget.com printable article Originally published November 30 2007 The Great Fat Debate - Why Virgin Coconut Oil Is Best by Teya Skae (NewsTarget) There is so much media hype from the mainstream media and leading health authorities, including the naturopathic community, suggesting the many ill effects of consuming Trans Fatty Acids (TFA's) that the topic of the Great Fat Debate deserves a closer look for the sake of our heath and understanding. Whilst there is unanimous agreement that TFA's are problematic and are to be avoided at all costs, some explanations are confusing at best or misleading at worst. It is time for more clarity so we can all choose the fats that are good and avoid those that are bad. Let's look at some of these warnings: Rekha Balu, writing for the Wall Street Journal, states that TFA's are like saturated fats "which raise bad cholesterol, causing a build-up of fatty deposits in the arteries." That is incorrect as saturated fats raise both the good and the bad cholesterol and they do not cause fatty deposits in the arteries. An under-active thyroid coupled with stress and a diet high in polyunsaturated oils cause a build-up of fatty deposits in the arteries. Lynn Roblin, writing for the Toronto Star, advises consumers to avoid TFA's by consuming more vegetable oils, such as olive oil and canola oil, in preference to butter and coconut oil. Let's remember that vegetable oils such as canola and safflower are rich in omega-6 fatty acids which have now been proven to cause oxidation of our cells. This reaction leads to inflammation which in turn promotes degenerative conditions and premature aging. Harvard nutritionist Frank Hu, featured in an article for the Washington Post, says butter is better than margarine, but tub or liquid margarine made from commercial vegetable oils is "a more healthful choice than butter." What Mr. Hu is promoting is the omega-6 fatty acids which have been hydrogenated and these are technically TFA's. Quite confusing indeed! Why is there so much confusion amongst health authorities in relation to fats? This is because in 1961, the American Heart Association published its first dietary guidelines aimed at the public. The authors, Dr. Ancel Keys, Irving Page, Jeremiah Stamler and Frederick Stare, called for the substitution of polyunsaturated oils for saturated fat. This was put forth even though Keys, Stare and Page had all previously noted in their published papers that the increase in Heart Disease was due to increasing consumption of vegetable oils. The 1961 report did not publish this fact, even after a 1956 paper by Dr. Keys suggested that the increasing use of partially hydrogenated vegetable oils (which is what TFA's technically are) is one of the culprits in the heart disease epidemic. Why was Dr. Keys report ignored? For obvious economic reasons the vegetable oil industry then squashed the reports on the dangers of vegetable oils and stealthily began their phony attack on making saturated fats - meat, eggs, cheese, butter and coconut oil responsible for heart disease. In actuality, saturated fats are shown to help in preventing heart disease. If we examine the health statistics along with the research on saturated fats consumption from the nations that consume large amounts of saturated fats in their diet, we find that they are among the healthiest nations /tribes/cultures in the world. Herein lies the big 'fat' confusion. Let's look closer at the FAT debate: TFA's are typically found in processed foods such as cookies, margarine, fried foods, fried potatoes, potato chips, crackers, breaded chicken, and fast food. McDonald's has admitted its french fries contain a third more TFA's than they had thought. In New York City, there are hefty fines imposed upon restaurants if they are not compliant with avoiding TFA's in their cooking; this ordinance took effect as of July 2007. Polyunsaturated Fats Defined Polyunsaturated oils are liquid at room temperature. Polyunsaturated fats such as Safflower, Corn, Sunflower, Soybean and Cottonseed Oils all contain over 50% omega-6 fatty acids. Safflower oil contains almost 80% omega-6. Researchers have now discovered there are dangers in consuming more of omega-6 oils in our diet then we need. The ideal ratio of omega-6 to omega-3 (the essential fatty acid) is 1:1. This is easily achieved if one avoids the use of vegetable oils as omega-6 is far more abundant in our diet then omega-3 essential fatty acids, which is found in cold water fish - salmon, sardines and mackerel. TFA's Defined In order to have polyunsaturated fats last longer and make them look more appealing, food manufacturers use a process called "hydrogenation". Hydrogenation is a process that takes unsaturated liquid fat (usually some kind of vegetable oil) and adds hydrogen. The result is a TFA. During hydrogenation, oil is heated to an extremely high temperature; this causes the oil to rapidly oxidize and create free-radicals. In basic chemistry 101, free radicals cause prolific cell damage and is responsible for premature aging. Even using the so called "healthiest" organic vegetable oils, which includes olive oil, in baking and frying creates free radicals. This is because all vegetable oils oxidize; especially when used in cooking. They not only produce TFA's but form free radicals - lethal combination for our bodies. The only oil that does not oxidize, even at 170 degree Celsius, is Organic Virgin Coconut oil which is a saturated fat. Amazing! Avoiding TFA's at all costs is a must according to the WHO (World Health Organization). This is because TFA's are injurious to the heart and have been linked to cancer, atherosclerosis, diabetes, obesity, immune system dysfunction, birth defects, difficulty in lactation, and problems with bones and tendons. So we want to exclude them from our diet, yet it is difficult when some of the most tempting foods such as commercial cakes, biscuits, chocolates, and potato chips are laden with TFA's. Why Saturated fats are not TFA's TFA's have similar properties to saturated fatty acids when used in baked goods, but the claim that TFA's are like saturated fatty acids is incorrect in view of their molecular bonding/structure and their biological effect in our bodies. This is the area that has been mostly ignored by mainstream media and even among the naturopathic community according to lipid and nutritional expert Dr. Mary G. Enig. Enig campaigned against TFA's back in the late 1970's after completing her most extensive research on the analysis of all fats. For more extensive information, see Mary G. Enig's PhD Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition (www.newtrendspublishing.com) So which oils do we use now? A good option is Organic Virgin Coconut oil. This is a saturated fat that is unlike any other fat and truly deserves a classification of its own. With all the research and studies on saturated fats to date, health authorities still group TFA's with healthy saturated fats like coconut oil. Coconut oil is not only the healthiest saturated fat but is one of the healthiest foods we can consume on a daily basis. Let's examine the most misunderstood fat that is actually a super food. Why is Coconut oil unique and unlike any other fat? Coconut oil is made up of medium-chain fatty acids (MCFA's). Two- thirds of the saturated fat in coconut oil is a medium-chain saturated fat. This important fact deserves clarification as MCFA's actually helps us to lose weight, lower cholesterol, improve diabetic conditions and reduce the risk of heart disease. One of the most outstanding benefits of consuming MCFA's is that they do not require the liver and gallbladder to digest and emulsify them. This means instant energy and increased thermogenesis (increased metabolic rate in the body) which leads to more heat production as well as improved circulation. For anyone with impaired fat digestion or a removed gallbladder, coconut oil is the only oil to consume as it is very easily digested. MCFA's are also known for having antimicrobial and anti-fungal properties, so they are beneficial to our immune system. In addition, coconut oil assists people with under-active thyroids by increasing the metabolic rate of the body and creating more energy. Ray Peat Ph.D., a physiologist who has worked with progesterone and related hormones since 1968, says that the sudden surge of polyunsaturated oils in the food chain post World War II has caused many changes in hormones. He writes: Their [polyunsaturated oils] best understood effect is their interference with the function of the thyroid gland. Polyunsaturated oils block thyroid hormone secretion, its movement in the circulatory system, and the response of tissues to the hormone. When the thyroid hormone is deficient, the body is generally exposed to increased levels of oestrogen. The thyroid hormone is essential for making the 'protective hormones' progesterone and pregnenolone, so these hormones are lowered when anything interferes with the function of the thyroid. The thyroid hormone is required for using and eliminating cholesterol, so cholesterol is likely to be raised by anything that blocks the thyroid function ( [link to www.efn.org] It is very interesting to note that high cholesterol is not a sign of eating too much saturated fat. High cholesterol in a lot of the cases is due to an under-active thyroid which affects the liver as well as the many loops and feedback systems within the endocrine system. Stress and the over consumption of carbohydrates/sugars also form high levels of cholesterol. What are saturated fats and why do we need them? Saturated fats are semi solid at room temperature and are found in animal products such as meat, poultry, lard, poultry skin, whole milk, cheese, eggs, butter and tropical oils such as coconut and palm oil. Our body actually needs saturated fats to stay healthy. Why? 1) Saturated fats constitute at least 50% of our cell's membranes - the phospholipid component of every cell. Saturated fatty acids are what gives our cells structural integrity, so the cell walls are not weak and can protect the inside of the cells. 2) Saturated fatty acids play a vital role in the health of our bones. For calcium to be effectively utilized by the bones, at least 50% of the dietary fats should be saturated. 3) Saturated fatty acids actually lower Lipoprotein (a), a substance in the blood that leads to heart disease, whereas excess consumption of vegetable oils increases it. 4) Saturated fatty acids protect the liver from alcohol and other toxins, including Tylenol, a pain reliever. 5) Saturated fatty acids are needed for the proper utilization of omega-3 essential fatty acids because omega-3's are better retained in the tissues when the diet is rich in saturated fats (particularly organic virgin coconut oil) 6) Saturated stearic acid found in beef and cocoa, and palmitic acid found in coconut oil are the preferred foods for the heart; which is why the fat around the heart muscle is highly saturated. The heart draws on this reserve of fat in times of stress. 7) Saturated fatty acids such as caprylic acid found abundantly in coconut oil, is anti fungal and helps combat candida (yeast overgrowth that is common in our society). 8) While saturated fats raise both the bad and the good cholesterol, TFA's as well as excess consumption of omega-6 fatty acids raise the bad Low Density Lipo-protein (LDL) and suppress the good High Density Lipo-protein (HDL) cholesterol, making it even worse. In conclusion, avoiding TFA's is a must. There are no tolerance levels. They are serious culprits of degenerative conditions disguised in some of the most tempting foods to date. Avoiding over consumption of polyunsaturated oils (omega-6 fatty acids) such as flax oil and completely avoiding corn, soy, safflower and canola is a great start, as polyunsaturated oils have been shown to contribute to heart disease, inflammation, under-active thyroid and weight gain. Use virgin organic coconut oil. I stress the importance of using only virgin organic coconut oil because the refined version of coconut oil no longer has the same structure and same health benefits as the virgin organic coconut oil. In fact, consuming plain coconut oil can even give someone a headache or nausea. The food manufacturers will not willingly return to using naturally saturated fats such as coconut oil, palm oil, butter and lard because they are more expensive. Only a concerted demand by educated consumers will bring traditional healthy fats back into our commercial food supply and restaurant cooking. Using organic coconut oil in all cooking and baking is the best choice for a healthy alternative. Because virgin coconut oil is completely saturated and no TFA's can be made from it, it is therefore harmless. In addition, it does not oxidize, even at 170 degrees Celsius. Virgin Coconut oil is the fat of fats as it also helps us burn body fat for energy because of its unique molecular structure of medium chain fatty acids. So do enjoy eating more organic virgin coconut oil, drinking organic coconut milk/crème in your teas as well as pouring it over your porridge and munching on macaroons made from organic cocoa and desiccated organic coconut for health and longevity.
