Is coconut oil and saturated fat bad for health?

Coconut oil is a saturated fat and was drilled into our minds as deadly, but is it really so? and saturated fats are they really bad? well recent researches prove that it is not the saturated fat that is the real culprit. the real problem is the trans fat found in all refined oils including refined coconut oil. pure Coconut oil contains medium chain fatty acids which bypasses the carnitine system and goes directly to the liver to be metabolized into energy. It increases thermogenesis and metabolism and reduces body weight. Virgin coconut oil also reduces LDL (bad cholesterol) and is the only oil in the planet that can increase HDL (good cholesterol). That” saturated fats are bad fats and can cause heart disease “needs to be seriously reconsidered. The diet heart hypothesis is also at stake as agreed by Framingham Heart Study Co-Director, Dr George Mann where he says "the diet heart hypothesis has been repeatedly shown to be wrong and yet for complicated reasons of pride and prejudice, the hypothesis continuues to be exploited by scientists, fund-raising enterprises, food companies and even governmental agencies.”The public is being deceived by te greatest health scam of the century". And according to Dr Willium Castelli the director of Framingham study " In Framingham studies,the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower people''s serum cholesterol.. we found that the people who ate most cholesterol,ate the most saturated fat,ate the most calories weighed the least and were the most physically active." It is now proven that coconut oil even destroys the Cytomegalovirus and Chlamydia pneumonia which is one of the responsible factors for initiating atherosclerosis. Our ancestors of south East Asia were all healthy when they consumed coconut products abundantly. A study conducted in Safdarjung, New Delhi (1998)[choice of cooking myths & realities] showed that the incidents of cancer, diabetes and heart disease arose when Indians stopped using traditional oils like coconut oil and mustard oil and started consuming the so called ''heart friendly'' cooking oils, which is full of trans fat, the culprit that causes all these diseases, obtained from hydrogenating and heating oils. one of the healthiest oil is virgin coconut oil. numerous researched have been done with VCO. Beneficial effects of virgin coconut oil on lipid parameters and in vitro LDL oxidation. by Nevin KG, Rajamohan T. Department of Biochemistry, University of Kerala, Kariavattom, Thiruvananthapuram 695 581, India..where they found It reduced total cholesterol, triglycerides, phospholipids, LDL, and VLDL cholesterol levels and increased HDL cholesterol in serum and tissues. The PF of virgin coconut oil was also found to be capable of preventing in vitro LDL oxidation with reduced carbonyl formation. CONCLUSION: The results demonstrated the potential beneficiary effect of virgin coconut oil in lowering lipid levels in serum and tissues and LDL oxidation by physiological oxidants. This property of VCO may be attributed to the biologically active polyphenol components present in the oil.According to Dr Mary Enig a renowed lipid biochemist,( who has done more than 20 years of research on fats) says, the problems for coconut oil started four decades ago when researchers fed animals hydrogenated coconut oil that was purposely altered to make it completely devoid of any essential fatty acids... The animals fed the hydrogenated coconut oil (as the only fat source) naturally became essential fatty acid deficient; their serum cholesterol increased. Diets that cause an essential fatty acid deficiency always produce an increase in serum cholesterol levels as well as in increase in the atherosclerotic indices. The same effect has also been seen when other ...highly hydrogenated oils such as cottonseesoybean or corn oils have been fed; so it is clearly a function of the hydrogenated products, either because the oil is essential fatty acid (EFA) deficient or because of transfatty acids." What about studies where animals were fed unprocessed coconut oil? Enig wrote: "Hostmark et al (1980) compared the effects of diets containing 10% coconut oil and 10% sunflower oil on lipoprotein distribution in male Wistar rats.
Coconut oil feeding produced significantly lower levels (p=0.05) of pre-beta lipoproteins (VLDL) and significantly higher (p=<0.01) alpha-lipoproteins (HDL) relative to sunflower feeding." (Editor''s note: HDLs are considered the good cholesterol as they prevent deposits of LDL cholesterol on artery walls.) She also cited a study by Awad (1981) on Wistar rats fed a diet of either 14% (natural) coconut oil or 14% safflower oil. She stated:"Total tissue cholesterol accumulation for animals on the safflower diet was six times greater than for animals fed the [unhydrogenated] coconut oil. A conclusion that can be drawn from some of the animal research is that feeding hydrogenated coconut oil devoid of essential fatty acids (EFA) ...potentate the formation of atherosclerosis markers. It is of note that animals fed regular coconut oil have less cholesterol deposited in their livers and other parts of their bodies." Enig also referred to epidemiological studies done by Kaunitz and Dayrit (1992) on coconut eating societies who found that "available population studies show that dietary pure coconut oil does not lead to high serum cholesterol nor to high coronary heart disease.." It is noteworthy that hydrogenated coconut oil was not consumed by these coconut eating societies; they only consumed natural coconut oil. her final conclusion was "everything the public has been told about vegetable oils on television for the past 15 years has been half truths and leading the public to the wrong conclusions. The public has been led to believe that tropicals will clog your arteries and cause heart disease. In fact, the opposite is true; natural tropical oils will help prevent hardening of the arteries while most liquid vegetable oils will increase hardening of the arteries!" As a practising Doctor in Oman for almost two decades, I find what the above researchers say is 100% correct in my experience with my patients, All my patients who avoid the refined oils and who switch on to virgin coconut oil, and olive oil ( olive oil is not to be cooked, for it is oxidized by light & heat.). and those who take a lot of fish and meat ( grilled not fried) are much healthier than those who use the so called " heart friendly" refined oils and consumed fried fish and meat. Virgin coconut oil can be safely used for cooking because it is nearly a completely saturated fat, which means it is much less susceptible to damage when it is heated, and the heat labile point of VCO is also very high. So I feel it is time for us to re evaluate our present knowledge and brain washed notion on saturated fats and cholesterol, and bring back into our patients their traditional eating habits which has been passed down from generation to generation and lead them to good health. As Doctor RusselL.Smith Phd (Author of authoritive study on CHD) has righty pointed out that "the relevant literature [on CHD] is permeated with fraudulent material that is designed to convert negative evidence into positive evidence with respect to lipid hypothesisi. that fraud is relatively easy to detect."

    so how do we know what to believe?

    what is good for us, what is bad for us? every other research claims complete opposites. it's very confusing.
