Research Coconut Oil

Excerpt from www.coconutoil.com :
Coconut oil is an edible oil that has been consumed in tropical places for thousands of years. Studies done on native diets high in coconut consumption show that these populations are generally in good health, and don't suffer as much from many of the modern diseases of western nations.
Coconut oil was once prevalent in western countries like the United States as well. With a long shelf life and a melting point of 76 degrees, it was a favorite in the baking industry. But a negative campaign against saturated fats in general, and the tropical oils in particular, led to most food manufacturers abandoning coconut oil in recent years in favor of hydrogenated polyunsaturated oils that come from the main cash crops in the US, particularly soy, and contain trans fatty acids. These polyunsaturated oils were not a big part of the diet of previous generations, so how has the health of Americans changed now that polyunsaturated oils are for the most part all one finds on supermarket shelves across the US? We encourage you to take an honest look at the research presented on this website, and consider the "other side" of the story, whether it be coconut oil, saturated fats, or the new vegetable oils!

Department of Medical Microbiology & Parasitology, University College Hospital, Ibadan, Nigeria.
The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungicidal actions, prompted this present study to characterize Candida species in our environment and determine the effectiveness of virgin coconut oil as an antifungal agent on these species. In 2004, 52 recent isolates of Candida species were obtained from clinical specimens sent to the Medical Microbiology Laboratory, University College Hospital, Ibadan, Nigeria. Their susceptibilities to virgin coconut oil and fluconazole were studied by using the agar-well diffusion technique. Candida albicans was the most common isolate from clinical specimens (17); others were Candida glabrata (nine), Candida tropicalis (seven), Candida parapsilosis (seven), Candida stellatoidea (six), and Candida krusei (six). C. albicans had the highest susceptibility to coconut oil (100%), with a minimum inhibitory concentration (MIC) of 25% (1:4 dilution), while fluconazole had 100% susceptibility at an MIC of 64 microg/mL (1:2 dilution). C. krusei showed the highest resistance to coconut oil with an MIC of 100% (undiluted), while fluconazole had an MIC of > 128 microg/mL. It is noteworthy that coconut oil was active against species of Candida at 100% concentration compared to fluconazole. Coconut oil should be used in the treatment of fungal infections in view of emerging drug-resistant Candida species.

The effects of high and low fat diets with identical polyunsaturated/saturated fatty acid (P/S) ratios on plasma postprandial levels of some hemostatic variables and on fasting lipoprotein (a) [Lp(a)] are not known. This controlled crossover study compared the effects of a high fat diet [38.4% of energy (E%) from fat; HSAFA-diet, P/S ratio 0.14], a low fat diet (19.7 E% from fat; LSAFA-diet, P/S ratio 0.17), both based on coconut oil, and a diet with a high content of monounsaturated fatty acids (MUFA) and PUFA (38.2 E% from fat; HUFA-diet, P/S ratio 1.9) on diurnal postprandial levels of some hemostatic variables (n = 11) and fasting levels of Lp(a) (n = 25). The postprandial plasma concentration of tissue plasminogen activator antigen (t-PA antigen) was decreased when the women consumed the HSAFA-diet compared with the HUFA-diet (P = 0.02). Plasma t-PA antigen was correlated with plasminogen activator inhibitor type 1 (PAI-1) activity when the participants consumed all three diets (Rs = 0.78, P < 0.01; Rs = 0.76, P < 0.01; Rs = 0.66, P = 0.03; on the HSAFA-, the LSAFA- and the HUFA-diet, respectively), although the diets did not affect the PAI-1 levels. There were no significant differences in postprandial variations in t-PA activity, factor VII coagulant activity or fibrinogen levels due to the diets. Serum fasting Lp(a) levels were lower when women consumed the HSAFA-diet (13%, P < 0.001) and tended to be lower when they consumed the LSAFA-diet (5.3%, P = 0.052) than when they consumed the HUFA-diet. Serum Lp(a) concentrations did not differ when the women consumed the HSAFA- and LSAFA-diets. In conclusion, our results indicate that a coconut oil-based diet (HSAFA-diet) lowers postprandial t-PA antigen concentration, and this may favorably affect the fibrinolytic system and the Lp(a) concentration compared with the HUFA-diet. The proportions of dietary saturated fatty acids more than the percentage of saturated fat energy seem to have a beneficial influence on Lp(a) levels.

The Health Benefits of Virgin Coconut Oil
Brian and Marianita Shilhavy
Marianita’s Story
I grew up in the Philippines during the 1960s and 1970s. My family lived in a small rural community of about 100 families. We lived on the side of a mountain, and everybody in our community earned their living from agriculture, primarily coconuts.
My father was a farmer, and his main crop was coconuts. He had some rice plantations and grew some other crops, and he was also the principal of our local government elementary school. But his main source of income in the 1960s and early 1970s was from coconuts. He made more money from the sale of his coconuts than he did as a school principal, for example. In the Philippines, the government provides education through 6th grade only in many places. High school and college are usually privately run and beyond the cost of most of the poor. My father sent all eight of his children to high school and college through the profits of the coconut industry, producing 3 school teachers, 1 nurse, 1 medical doctor, and myself, a nutritionist/dietician.
The people in our farming community while I was growing up primarily ate food that they had grown or raised themselves. Our diet consisted mainly of rice, coconuts, vegetables and root crops, herbs (especially garlic and ginger), and some meat that was raised locally. Trips to the market were made once a week to buy primarily fresh fish caught in the ports nearby. While my parents’ generation would have grinded their own rice by hand, leaving in tact most of the bran and nutrients, after World War II during my time rice mills starting popping up making it easier to mill rice. The first mills used in my day were “crude,” and did not polish the rice, so we basically still ate healthy grains which today would be considered low-carb. Later, the mills became more sophisticated and began to polish the rice making it bright white. All of our food back then would be considered “organic” by today’s standards, as we had no access to chemical fertilizers or pesticides. Living in a tropical climate, our animals, such as chickens, cows, goats, etc., all grazed on natural green vegetation.
Coconut and coconut oil was used daily. My parents’ generation made coconut oil by hand using either the boiling or fermentation method. After World War II desiccated coconut plants and coconut oil mills were established for the booming baking industry in the US. Refined coconut oil started to make its way into the local economy as well, but at that time even the refined coconut oil made from copra (dried coconut meat) was done through a mechanical pressing that did not use solvent extracts. While some people still made coconut oil the “old fashioned” way, many began buying the cheaper, odorless coconut oil in the markets. Our natural diet was definitely a high-fat diet, a diet high in the saturated fat of coconut oil.
So what was the health of the people like in our community, where everyone ate a diet high in the saturated fat of coconut oil? Our community was part of a larger community of some 50,000 people that was served by a single government doctor in those days. While pharmaceuticals began to be manufactured in the Philippines after World War II, people in communities like ours could not afford them. We had our own traditions of dealing with simple sicknesses using local herbs and coconut oil. When people did go to town to visit the local government doctor, it was usually not for the kind of ailments that westerners go to the doctor today, such as diabetes, cancer, heart disease, thyroid problems, etc. These illnesses were virtually unknown in my younger days. People went to see the doctor to treat wounds, or from sicknesses common in the tropics, such as malaria, diarrhea, dengue, etc. My father was well into his 60s before he made his first visit to the doctor, and that was for a head wound. He died in the late 1980s in a car accident in the U.S. He was in his 70s and in perfect health. Three of his older sisters still survive him to this day and are in great health. One is in her 90s. One of his sisters, my aunt, is in her late 80s and still lives in the remote area of the Philippines where I grew up, eating a traditional diet. She taught us how her generation made coconut oil by hand, which is the basis for the Tropical Traditions Virgin Coconut Oil, the most popular Virgin Coconut Oil sold in the U.S. She still shuns modern conveniences (such as electricity) and eats mostly all food that she herself has grown on her farm, and she has excellent health. Her first visit to a doctor was when she was in her early 80s. I myself have no memory of being sick growing up. I suffered my first “cold” when I was in my 30s, after I married my American husband and spent a year in the U.S. eating typical U.S. food found in grocery stores.
This picture of life in the rural Philippines is typical of those who grew up in my generation or my parents’ generation, eating traditional foods with an abundance of saturated fat found in coconut oil. Sadly, it is no longer true today. Since the mid-1970s demand for coconut oil fell so low that coconut farmers could no longer afford to support their family on the income of coconut harvests. Many people left the farms and went to the cities to find better employment, and soon adopted new dietary trends similar to western diets. Cheaper mass-produced industrial foods, particularly meats, now replace most of the local traditional foods we used to grow or raise ourselves. Snack foods and other fast foods are now made with hydrogenated coconut oil to keep it solid at the high air temperatures experienced in our tropical climate. The rice is now polished and grown with chemical fertilizers, and soft drinks loaded with refined sugars are found on every street corner, replacing the natural “buko juice”, the water from the inside of the coconuts, that my generation grew up drinking. Even the coconut water drinks still sold are usually loaded with refined sugars. Our traditional, high-fat low-carb diet has been replaced with many refined high-carb substitutes. Growing up it was very rare to see anyone considered overweight, and almost never considered “obese”, but even that is changing now as the diet has changed also.

Population Studies
There are quite a few studies that have been done on traditional diets in tropical areas that are high in coconut oil consumption. These studies back up the fact that Marianita’s experience growing up in the Philippines is common in cultures that derive much of their caloric intake from the saturated fats of coconut oil. In a study published in 1981, the populations of two South Pacific islands (Pukapuka and Tokelau) were examined over a period of time starting in the 1960s, before western foods were prevalent in the diets of either culture. The study was designed to investigate the relative effects of saturated fat and dietary cholesterol in determining serum cholesterol levels. Coconuts were practically a staple in the diets, with up to 60% of their caloric intake coming from the saturated fat of coconut oil. The study found very lean and healthy people who were relatively free from the modern diseases of western cultures, including obesity. Their conclusion: "Vascular disease is uncommon in both populations and there is no evidence of the high saturated fat intake having a harmful effect in these populations."1
My friend Nida's grandmother has continued to prepare coconut oil in the [traditional] manner... She is also a manghihilot. The herbs she adds are, among others, garlic and ginger. She rubs it on herself and her husband every night. They are still healthy. Nida tells of her cousins who were very poor. So poor, in fact, that they ate mostly coconut. Other kids teased them because they ate fresh coconut for breakfast instead of rice and fish, and munched it whenever they were hungry, picking it up from the copra being laid out to dry. These kids ended up being the healthiest in the neighborhood, fat, with smooth, shiny skin and good teeth! As teenagers, they never had skin eruptions. Luanne, Mindanao, Philippines
Other studies done among the Pacific islands were conducted back in the 1930s by Dr. Weston Price, a dentist. Dr. Price spent significant time traveling and examining traditional cultures, their diet, and dental and overall health, as compared to those eating more modern diets consisting of refined foods. His work is documented in the book Nutrition and Physical Degeneration (1939 Keats Publishing). As he traveled to islands throughout the South Pacific, he found the same thing wherever he went. Those eating a traditional diet consisting of high concentrations of coconut were in very good health, and were not obese even though they had such a high fat content in their diet. Those who through commercial trade with western countries were starting to eat more refined foods high in carbohydrates were starting to suffer common western diseases, including dental decay.
In India a study was done comparing traditional cooking oils, like coconut oil and ghee which are rich in saturated fats, with modern oils like sunflower or safflower oils which are mostly polyunsaturated, in relation to prevalence of heart disease and Type-II diabetes. The study was done by the Department of Medicine, at Safdarjang Hospital in New Delhi. The study was titled “Choice of cooking oils--myths and realities”, and was published in the Journal of the Indian Medical Association in 1998. They found that while saturated fats were portrayed as unhealthy in favor of newer polyunsaturated vegetable oils, that heart disease and diabetes had actually increased after consumption of the traditional oils like coconut oil and ghee decreased.2 Weight gain typically is associated with heart disease and diabetes. They concluded that these newer "heart-friendly" oils like sunflower or safflower oils possess an undesirable Omega 6 fatty acid ratio to Omega 3 fatty acids,  and that there are numerous research data now available to indicate that the sole use or excess intake of these newer vegetable oils are actually detrimental to the health of Indians.
My wife and I have been using the Virgin Coconut Oil for about 3 months now (a teaspoon in the morning and at night). We have noticed increased energy along with a decrease in the amount of time it takes to overcome viruses. We attribute this to the anti-viral properties of the virgin coconut oil. Also, we use the oil as a moisturizer and have noticed less dryness of our skin in our dry winter climate. Tom Rutland, Vermont
P.K. Thampan, the former Chief Coconut Development officer of Coconut Development Board in India, has found the same thing true in his studies of traditional cultures consuming large amounts of coconut. In his book “'Facts and Fallacies about Coconut Oil” Thampan shows that population studies conducted in countries where coconut oil is a part of the normal diet of the people have revealed that coconut oil consumption is unrelated to coronary heart disease mortality and morbidity, which is contrary to what is being taught in many of these countries. Observations recorded in these countries, where coconut kernel and coconut oil form major dietary components, have shown a longer life expectancy at birth than in countries with negligible intake of coconut products. There are also instances of longer life expectancy in predominantly coconut-consuming areas than in other places within the same country that eat less coconut.3
Dr. P. Rethinam and Muhartoyo wrote in the Jakarta Post, on June 18, 2003, that before 1950, heart attacks were not common in Sri Lanka. However, hospital admission rates for heart attacks grew dramatically from 1970 to 1992. On the other hand, the Central Bank of Sri Lanka had determined that the coconut consumption has gone down from 132 nuts per person per year in 1952 to 90 per person per year in 1991. Because of the saturated fat scare of recent years condemning coconut oil, people ate fewer coconuts and heart disease and the associated weight gain actually increased! H. Kaunitz wrote in 1986 that the 1978 edition of the Demographic Yearbook of the United Nations reported that Sri Lanka had the lowest death rate from ischemic heart disease, while coconut oil was their main dietary fat.4
The Research
So how do people in the tropics do it? How can people on traditional diets consume so much saturated fat and remain slim and healthy?
Researchers have known for quite some time that the secret to health and weight loss associated with coconut oil is related to the length of the fatty acid chains contained in coconut oil. Coconut oil contains what are called medium chain fatty acids, or medium chain triglycerides (MCTs for short). These medium chain fatty acids are different from the common longer chain fatty acids found in other plant-based oils. Most vegetable oils are composed of longer chain fatty acids, or triglycerides (LCTs). LCTs are typically stored in the body as fat, while MCTs are burned for energy. MCTs burn up quickly in the body.  They are a lot like adding kindling to a fireplace, rather than a big damp log.
Coconut oil is nature’s richest source of MCTs.  Not only do MCTs raise the body’s metabolism leading to weight loss, but they have special health-giving properties as well. The most predominant MCT in coconut oil, for example, is lauric acid. Lipid researcher Dr. Jon Kabara states “Never before in the history of man is it so important to emphasize the value of Lauric Oils. The medium-chain fats in coconut oil are similar to fats in mother’s milk and have similar nutriceutical effects. These health effects were recognized centuries ago in Ayurvedic medicine. Modern research has now found a common link between these two natural health products----their fat or lipid content. The medium chain fatty acids and monoglycerides found primarily in coconut oil and mother’s milk have miraculous healing power.”5 Outside of a human mother’s breast milk, coconut oil is nature’s most abundant source of lauric acid and medium chain fatty acids.
I have personal experience with using Virgin Coconut Oil (VCO) to richen my milk supply :) In fact, this is why I started taking VCO in the first place. My baby was very low weight and I just knew that something wasn't right. Our pediatrician was no help~ he said because she hadn't lost weight, she was fine. I finally went to a naturopathic doctor, and explained my situation (besides the baby gaining only a few ounces, I had PPD). Since my baby was my 9th and I'd nursed the last 6... He said that I probably didn't have enough good fats in my system. That would account for my milk not being rich enough/full of fat to help her grow, and it also probably had a great deal to do with my hormones being out of whack and me struggling with PPD. I started taking VCO when the baby was 5 months old. By the time she was 7 months old, she'd gained 3 whole pounds! My PPD had disappeared also :)
 
We went back for a weight check when the baby was 9 months old, and she had gained another 2 pounds and was not only back on the weight chart, but on the correct curve for her age, etc. I had also noticed that she was developing new skills all at once, that maybe she'd not been able to before. My pediatrician was so impressed he asked me what I'd done... I was a little nervous about telling him, but truthfully, the only thing I'd done differently was to take the VCO! So I told him and he never rolled his eyes or treated me like I'd lost my mind ;-) He even wrote it in her chart! Jan El Paso, TX
Much of the recent research done on coconut oil and lauric acid, the most predominant fatty acid chain found in coconut oil, has centered around the anti-microbial and anti-viral properties of this unique fatty acid. Today, many strains of bacteria are becoming resistant to antibiotics, and antibiotics are generally ineffective in treating virus infections. When lauric acid is consumed in the diet, either in human breast milk or in coconut oil, lauric acid forms a monoglyceride called monolaurin, which has been shown to destroy several bacteria and viruses, including listeria monocytogenes and helicobacter pylori, and protozoa such as giardia lamblia.  Some of the viruses that have been destroyed by monolaurin include HIV, measles, herpes simplex virus-1, vesicular stomatitis virus, influenza and cytomegalovirus.6 There is also evidence now that the MCTs in coconut oil kill yeast infections, such as Candida.7
So now that we know that these wonderful health benefits found of coconut oil that lead to weight loss and vibrant health are in the fatty acids of coconut oil, the question that begs to be answered is why hasn’t this secret been revealed in the past?
The answer is that is has! The incredible health properties of MCTs was researched and documented by people like Dr. Jon Kabara as far back as 1966. MCTs have been part of infant formulas and hospital formulas for many years. The food industry at one time considered coconut oil to be the most superior dietary oil for use in baking and food preparations. At one time, it was a significant part of the American diet.
Our whole family is really enjoying your Virgin Coconut Oil.  The original purpose for the purchase was because we have a special needs child who has quadriplegic cerebral palsy and cortical blindness.  Unlike most children in her condition, our daughter is fed pureed foods orally and given liquids via gastrostomy tube.  She is able to tolerate very few proteins and fats because of the extremely slow movement of her digestive system.  Your Virgin Coconut Oil is gentle on her system and she tolerates it wonderfully.  This is such an accomplishment since there are only a few oils available that she is able to obtain nourishment and sustenance from.  The taste is pleasant and mild, and we are always pleased to provide her with foods that are whole and unprocessed.  Much to the surprise of her many doctors, she continues to gain weight steadily, although she is small for her age.  The nutritional consultants at the hospital where she receives all necessary care (recently noted to be one of the top ten in the country) continue to instruct us with regard to her nutrition "just keep doing whatever you are doing because she is thriving wonderfully."  They have no explanation for her wonderful skin, great immune system, and weight gain-  all areas in which children like her struggle for daily their entire lives.  We thank God for such wonderful foods as the coconut, for blessing her with great health, and for companies such as yours (Tropical Traditions) who can provide quality products with great integrity.

However, during World War II when the Japanese occupied most of the South Pacific and the Philippines, supplies of coconut oil were cut off for several years. Americans were forced to turn to alternative sources for cooking oils, and this is when many of the polyunsaturated oils began to make their way into the market place.
How Did Coconut Oil Get Such a Bad Reputation?
Beginning in the 1950s, public opinion towards saturated fats in general, and then later towards coconut oil in particular, began to turn negative. This history of the edible oil industry in the US has been well documented by Dr. Mary Enig, Ph.D., and can be read at www.coconutoil.com or at the Weston Price Foundation website (www.westonaprice.org). Her articles “The Oiling of American” and “Coconut: In Support of Good Health in the 21st Century” provide in depth analysis of the saturated fat research, and the negative campaigns that have been waged against coconut oil.
The anti saturated fat theory apparently began in the 1950s, with the steep rise of heart disease. While heart disease probably caused no more than 10% of all deaths in the U.S. prior to the 1920s, by the 1950s it had risen to more than 30% of all deaths. Researchers were looking for the cause of this new threat to the nation’s health. Some researchers suggested that cholesterol levels were the problem, and that saturated fats raised cholesterol levels. One such study was based on examining the artery plaques found in American soldiers who had died in Korea. With high levels of cholesterol found in artery plaques, some started looking at cholesterol levels found in foods as a possible cause. Cholesterol is found only in animal foods such as meat, fish, cheese, eggs and butter. Soon a “lipid hypothesis” was formed that stated “saturated fat and cholesterol from animal sources raise cholesterol levels in the blood, leading to deposition of cholesterol and fatty material as pathogenic plaques in the arteries.” So the traditional foods of butter, eggs, and fat from meats were “out”, and the new vegetable oils were seen as heart-healthy replacements. However, research now shows that cholesterol levels in food have little or no effect on blood cholesterol levels, and the whole lipid theory of heart disease has been rejected by many researchers and doctors. Malcom Kendrick M.D., Dr. Mary Enig Ph.D., Uffe Ravnskov M.D., Ph.D (author of The Cholesterol Myths), George Mann M.D., Sc.D, and many other top researchers have written extensively on the flaws of the “cholesterol theory” of heart disease.
So what was the cause of the rapid rise of heart disease in the US? While there are many factors to consider, one thing we know is that after World War II there were some significant dietary changes in the American diet, including that kinds of fats Americans were eating. As Mary Enig reports:
Butter consumption was declining while the use of vegetable oils, especially oils that had been hardened to resemble butter by a process called hydrogenation, was increasing—dramatically increasing. By 1950 butter consumption had dropped from eighteen pounds per person per year to just over ten. Margarine filled in the gap, rising from about two pounds per person at the turn of the century to about eight. Consumption of vegetable shortening—used in crackers and baked goods—remained relatively steady at about twelve pounds per person per year but vegetable oil consumption had more than tripled—from just under three pounds per person per year to more than ten.8
What we know today, but was not known well in the 1950s, is that hydrogenated and partially hydrogenated vegetable oils create trans fatty acids that have been linked to heart disease. (see below)
Coconut Oil: the Center of Attack
The saturated fats/cholesterol scare soon became mainstream thinking, however, and before long certain groups began taking aim at the saturated fats found in coconut oil. At one time coconut oil was a significant part of the American diet.  Suddenly, we were told to avoid anything with tropical oils—from theater popcorn oil to packaged snack foods, which was a complete turn from when the food industry considered coconut oil to be an excellent dietary oil for use in baking and food preparations.
Dr. Mary Enig states:
The coconut industry has suffered more than three decades of abusive rhetoric from the consumer activist group Center for Science in the Public Interest (CSPI), from the American Soybean Association (ASA) and other members of the edible oil industry, and from those in the medical and scientific community who learned their misinformation from groups like CSPI and ASA. According to one of CSPI’s own press releases, "In 1984, CSPI organized the first national campaign to pressure fast-food restaurants and food companies to stop frying with beef fat and tropical oils, which are high in the cholesterol-raising saturated fats that increase the risk of heart disease. After six years of public pressure—including full-page newspaper ads placed by Nebraska millionaire and cholesterol-crusader Phil Sokolof—the industry finally relented in 1990.”9
Congress held hearings in 1988 to discuss the safety of tropical oils. Dr. George Blackburn, a Harvard medical researcher, testified that coconut oil has a neutral effect on blood cholesterol, even in situations where coconut oil is the sole source of fat. Surgeon General C. Everett Koop dismissed the entire attacks on coconut oil as “Foolishness,” and continued to say “but to get the word to commercial interests terrorizing the public about nothing is another matter.” However, with no strong political influence in Washington from the coconut-producing countries, the ASA and CSPI prevailed and soon coconut oil almost vanished from the American diet. At one time a significant part of the American diet, today it has been replaced by the so called “healthier” vegetable oils.

The Replacement for Saturated fats: Toxic Oils

Today, walk into any major grocery or retail food chain, visit the cooking oil section and you will not find much in the way of saturated fats. What have replaced saturated fats are now liquid vegetable oils, also known as polyunsaturated oils.
Unfortunately, polyunsaturated oils are not stable and they are prone to oxidation. These commercial vegetable oils are a recent addition to our diet since World War II, when manufacturers developed a process to make them shelf stable by using hydrogenation. Hydrogenating, or partially hydrogenating these oils, also makes them more solid (mimicking saturated fats) and useful for baking and deep frying.
Research now shows that the processing of these polyunsaturated oils creates a whole new subclass of fats called trans fatty acids. These trans fatty acids are not found in nature, and are very toxic. Studies are now showing that trans fatty acids are linked to cardiovascular disease, diabetes, and cancer, among others. In January 2004 Denmark became the first country in the world to ban the manufacture of trans fatty acids in its foods.10  In Europe, the consumption of trans fatty acids is decreasing. In the U.S., the FDA is requiring all food manufacturers to list trans fatty acids in the nutrition panel of their labels by the year 2006. The FDA website states:
On July 9, 2003, FDA issued a regulation requiring manufacturers to list trans fatty acids, or trans fat, on the Nutrition Facts panel of foods and some dietary supplements. With this rule, consumers have more information to make healthier food choices that could lower their consumption of trans fat as part of a heart-healthy diet. Scientific reports have confirmed the relationship between trans fat and an increased risk of coronary heart disease. Food manufacturers have until Jan. 1, 2006, to list trans fat on the nutrition label. FDA estimates that by three years after that date, trans fat labeling will have prevented from 600 to 1,200 cases of coronary heart disease and 250 to 500 deaths each year.11
What are the polyunsaturated oils commercially processed in the US containing trans fatty acids? Soy, corn, cottonseed, and safflower are the most common. 90% of all margarines in the US today are made from soy oil, and loaded with trans fatty acids. These are the very fats that CSPI promoted as a replacement for saturated fats back in the 1980s. As Dr. Mary Enig writes:
The whitewash of trans fatty acids began in 1987 with an article by Elaine Blume, published in CSPI's Nutrition Action newsletter. Wrote Blume: "From margarine to Tater Tots, partially hydrogenated vegetable oils play a major role in our food supply. . . . In fact, hydrogenated oils don't post a dire threat to health. . . . Improving on Nature. . . . Manufacturers hydrogenate. . . these vegetable oils so they won't become rancid while they sit on shelves, or during frying. . . . it seems unlikely that hydrogenation contributes much to our burden of heart disease. . . The fact that hydrogenated oils appear to be relatively benign is cause for thanks, because these fats are everywhere."
In 1988, CSPI published a booklet called Saturated Fat Attack, which defended trans fatty acids and partially hydrogenated vegetable oils and called for pejorative labeling of "saturated" fats. The booklet contained a section called "Biochemistry 101," which claimed that only tropical oils were dangerous when hydrogenated. "Hydrogenated (or partially hydrogenated) fats are widely used in foods and cause untold consternation among consumers. . . [they] start out as plain old liquid vegetable oils (usually soybean), which are then reacted with hydrogen. . . converting much of the polyunsaturated fatty acids to monounsaturated fatty acids. . . [with]. . . small amounts. . . converted to saturated fatty acids. . . [e.g.], stearic acid, which seems to have no effect on blood cholesterol levels.
"Overall, hydrogenated fats don't pose a significant risk. . . exceptions are hydrogenated [tropical oils, which are made]. . . even worse after hydrogenation."
Obviously, the individuals writing the booklet were completely ignorant (or pretended to be ignorant) of lipid science. Modern hydrogenation methods create trans fatty acids rather than monounsaturated fatty acids, and very few saturated fatty acids. By 1988, the adverse effects of trans fats were well known. The article points out that stearic acid has no effect on blood cholesterol levels, yet CSPI continued to accuse beef tallow, which is rich in stearic acid, of "raising cholesterol and increasing the risk of heart disease." As for the tropical oils, they do not need to be hydrogenated!12
By 1990 the dangers of trans fats from hydrogenated vegetable oils was so well documented, that CSPI had to completely change their position. As Dr. Enig writes:
The revisionism began in December 1992 when Ms. Liebman wrote: "We've been crying 'foul' for some time now, as the margarine industry has tried to convince people that eating margarine was as good for their hearts as aerobic exercise. . . . And we warned folks several years ago that trans fatty acids could be a problem. . . . That's especially true now that we know that trans fatty acids are harmful, but we don't know how much trans are in different foods." Of course, CSPI had issued no such warning, but had been defending trans fats for more than five years. And there's no apology for falsely demonizing traditional fats.

The Benefits of Saturated Fats
Most of the fats in the diet of our forefathers were saturated fats. This is also true of many traditional cultures. Tropical diets, for example, get much of their fats from coconuts and palm oil, which are rich in saturated fats. As we have seen with our experience in the Philippines, these traditional cultures have not had the obesity and health problems that we are seeing today in our culture, even though they had a diet high in saturated fats.
At 2 years of age, my daughter was screaming, grunting and pointing and grunting for most things.  She had a very small vocabulary (despite us trying to teach her words for things).  We discovered that a cousin of hers has NIDS and started researching to find out if our daughter might have NIDS as well. NIDS is NeuroImmune Dysfunction Syndrome.  Basically it says there is a virus attacking the brain that causes Autism, ADD, ADHD and CFS and the whole range in-between (including apraxia).  Her son was put on a ton of pills in order to help him (antivirals, antibacterials, antifungals and others).  Since coconut oil is a known NATURAL antiviral, antibacterial and antifungal, I figured it could not hurt to try it. So I immediately replaced all our cooking oils with coconut oil.  I also gave her a supplement of coconut oil (1-2 teaspoons a day).
While I have no scientific proof that coconut oil helped my daughter, within days she was speaking more words.  She was also trying harder to communicate.  She is now 2 1/2 and speaking 3-4 word sentences!  Her speech is still a little delayed (she has difficulty forming the words - I believe she has always had apraxia, but there has been no official diagnosis), and she is sometimes a little difficult to understand (not able to pronounce clearly).  But she no longer grunts and points at objects.  She even tells me "I love you Mommy." I will continue to give my daughter coconut oil because I truly feel that it is helping her.  And I am thankful that we did not have to give her all those pills her cousin is on!

One reason why saturated fats have a long history of use in traditional cultures is because they are very stable fats that do not easily oxidize (turn rancid). Virgin Coconut Oil, for example, will not go rancid even at room temperatures in the tropics for a couple of years. Conversely, the refined oils that many Americans use are very unstable and turn rancid (oxidize) quickly.  Oxidized oils are very toxic to the body and they can cause wide spread free-radical damage.
In addition to their shelf stability, saturated fats have many important roles in the body’s chemistry: For example:

Ceylon Medical Journal on coconut fats

There is the need to clarify issues relating to intake of coconut fats and health, more particularly for populations that still depend on coconut fats for much of their fat intake.
This paper describes the metabolism of coconut fats and its potential benefits, and attempts to highlight its benefits to remove certain misconceptions regarding its use.
Coconut consumption and lipid patterns in Sri Lanka
A recent study has shown that in Sri Lanka, whereas 91 per cent of the poor still consume coconut as their main source of fat, only 70 per cent of those earning more than Rs. 5,000 use coconut oil.
The amount of coconut consumed is less than 5 years ago for 75 per cent of those surveyed. Thus study also found that one of the reasons for reduced coconut consumption was a misconception that coconut fats are bad. The misconception has arisen due to the fact that coconut fat is mainly saturated fat, and saturated fats are synonymous with atherosclerosis, ischaemic heart disease and cerebrovascular disease.
There remains the question whether coconut fats have actions other than those in relation to lipid hypothesis of atherosclerosis, ischaemic heart disease and cerebrovascular disease which need to be considered when answering the above question. Ischemic heart disease
To answer that, one would have to first look at coconut consumption and possible relationship to the prevalence of ischaemic heart disease and cerebrovascular disease in Sri Lanka. Kaunitz states that the Demographic Yearbook of the United Nations (1978) reported that Sri Lanka has the lowest death rate from ischaemic heart disease.
Sri Lanka was quoted as being the only country giving reliable data where coconut oil is the main dietary fat. This was at a time when average coconut consumption was around 130 nuts/person/year.
On the other hand, according to Abeywardena, the incidence of ischaemic heart disease and cerebrovascular disease in Sri Lanka is increasing at an alarming rate and is similar to that of the developed world. Central Bank of Sri Lanka reports show that the coconut consumption has now declined to around 100-110 nuts/person/year.

Are coconut fats the culprit

Under the circumstances, are coconut fats the culprit or have they been given a bad name simply by virtue of its fat being greater than 90 per cent saturated fat?
Epidemiologic studies both in Sri Lanka and elsewhere, have failed to clearly establish a relationship between coconut fats, atherosclerosis and ischaemic heart disease.
The classic study by Prior among Pacific islanders whose diet contained large amounts of coconut showed a low prevalence of heart disease, cancer, diabetes and arthritis.
Mendis has attributed this to a 'protective effect' of omega-3 fatty acids from the fish these people ate. Other, more recent studies on small population samples have failed to establish a clear link between consumption of coconut products and atherosclerosis, ischaemic heart disease and cerebrovascular disease.
Case control studies comparing the diet of patients with ischaemic heart disease and controls have come out both for and against a causative role for coconut fats.

Coconut fats and lipids

The possible role of coconut fats in disturbances of lipid metabolism is also not well established. Many allopathic medical practitioners seem to think that, as coconut fats are saturated, they elevate plasma lipids in the same manner as the saturated fats from animal sources.
Adding to the misconception is the fact that many of the animal studies on the role of coconut fats in lipid metabolism have used hydrogenated coconut oil. This is an unnatural form of coconut oil that is purposely altered to make it completely devoid of any essential fatty acids.
The conclusion that can be drawn from such animal research is that feeding hydrogenated coconut oil devoid of essential fatty acids enhances the formation of atherosclerosis markers. However, coconut oil, unlike much of the soybean and corn oil consumed both here and abroad, is free of hydrogenated fat and hence transfatty acids.
In human feeding studies, coconut fats without doubt elevate high density lipoprotein (HDL) cholesterol. The effect on total cholesterol and low density lipoprotein (LDL) cholesterol is probably neutral. It is also possible that women may react differently to men when fed a coconut diet.
A Sri Lankan study found that the risk of coronary heart disease as assessed by the body mass index, ratios of total cholesterol to HDL-cholesterol, and LDL-cholesterol to HDL-cholesterol, was significantly lower in subjects in rural areas, who were agricultural workers with a high degree of physical activity, subsisting on a diet consisting mainly of plant food, despite a higher consumption of coconut, a saturated fat.
This study also suggest that hyperlipidaemia is more common among urban dwellers than among the rural population. This difference was attributed to lower fruit, vegetable and fibre content in the diet and lower physical activity among the urban population. Yet from Peiris' study we know the rural poor consume more coconut than city dwellers.
Abeywardena has proposed that a low fat diet with predominantly coconut fat may lead to the 'metabolic syndrome' and thus be associated with the increasing prevalence of ischaemic heart disease and cerebrovascular disease. However, this needs to be proven by good epidemiologic studies.
Virgin coconut oil when fed to rats is reported to lower lipid levels in serum and tissues, and LDL oxidation.
This property of virgin coconut oil is attributed to the biologically active polyphenol components present in the oil. Other studies have shown that consumption of a solid fat rich in lauric acid gives a more favourable serum lipoprotein pattern than consumption of partially hydrogenated soybean oil rich in trans-fatty acids.

Other effects of coconut oil

What of the claim that coconut fats decrease platelet adhesiveness? Hard data are not readily available. A 1993 study comparing a high fat diet (50 per cent of total energy) to a low fat diet (20 per cent) suggested that the high fat diet might increase blood thrombogenicity by virtue of augmented postprandial activation of factor VII. A more recent 2003 study showed that a lesser increase in FVIIa occurred after the consumption of saturated fats, than after unsaturated test fats.
Others have attempted to study the effects of individual fatty acids on whole blood aggregation and concluded that compared to oleic acid, lauric, myristic or palmitic acids do not effect in vitro whole blood aggregation induced by collagen ADP-induced aggregation.
Compared to a high unsaturated fat or high polyunsaturated fat diet, a coconut oil-based diet lowers postprandial t-PA antigen concentration, and this may favourably affect the fibrinolytic system and the Lp (a) concentration.
What of other benefits that may accrue from eating coconut oil? Many readers may not be aware of the close similarity among the medium chain triglycerides in coconut fats, human breast milk and the secretion of sebaceous glands, all rich in lauric acid.
Monolaurin and even lauric acid have been shown to be bactericidal, particularly against Helicobater pylori, Vibrio cholerae, Salmonella typhi, Shigella sonnei and enterotoxigenic Escheichia coli. coconut oil also helps the body to increase absorption of calcium and magnesium ions.
It has been suggested that coconut oil is used to supplement treatment of rickets in poorly developed countries, alongside infant formulae supplemented with these inorganic ions.
No work has been done with coconut fats per se. However, it is interesting to speculate whether monolaurin and lauric acid released by pre-gastric lipase may contribute to the reported low incidence of Helicobacter pylori infection in Sri Lanka compared to other South Asian countries.

Immune system

Current understanding based on the effect of dietary lipid manipulation upon immune system function indicates that fatty acids are involved in the modulation of the immune response through complex pathways.
The problem with many animal studies is that they use hydrogenated coconut oil. One study where non-hydrogenated coconut oil was used showed that lipopolysaccharide-stimulated TNF-alpha production by macrophages decreased with increasing unsaturated fatty acid content of the diet.


World peace flag with baby emblem -D.W.A.

Doctors Wives Association will call for the adoption of a flag by the UN with a baby just born emblem, as the UN peace flag for the whole world, if possible.
This will be done this Sunday at the HealthWatch children's crossword draw on peace and amity to be held at the Wijerama Mawatha auditorium of the SLMA.
The DWA president Chrissy Aloysius said this follows a poem on the subject published in the Poetry Corner of the Daily News on January 25, 2006 by the HealthWatch, coordinator under the 'Just Born' heading, calling for the necessity to change the present peace emblem of the dove, to a baby just born as the emblem and make it the peace flag for the whole world, which the DWA felt was a very timely need, and a very simple and realistic step towards peace and unity in the world which the women folk should take up, and push forward.
She said "We discussed this and at our last meeting we had one of our members Nalini de Alwis to carry a baby and show the world how realistically and movingly it depicts how the people in the world could be moved to gather around a baby for peace and unity flag."

Foreign doctors likely to sit local diploma in Clinical Hypnotism

The local diploma course in clinical hypnotism conducted by the Sri Lanka College of General Practitioners (CGP) is likely to be taken up by several doctors in India and Pakistan shortly. This was revealed to the HealthWatch by the head of the CGP Clinical Hypnotic Examination Unit, Dr. H. B. Jayasinghe. He said that several requests made by doctors in these two countries to follow this course and sit the examination is now being taken up by the CGP with the PGIM. Last week the CGP had its Diploma examination for Clinical Hypnotism for local doctors for the third year. These doctors have to undergo one year training course at the CGP before they sit the exam. This year, six doctors took up this diploma examination. At present there are 26 doctors in the country who have passed this exam and practising this therapy.
