Many have been led to believe that a diet low in fat will that losing weight and increasing your cholesterol. Unfortunately, this could not be further from the truth. Most people are still afraid to eat fat – fat. They believe that a low-fat diet will help you lose weight and help prevent heart disease. In fact, the opposite may be true. Low-fat diets recommended by most nutritionists and dietitians are not only totally useless, they are also dangerous.
The New York Times has published a great article on low-fat obsession in the United States, “In 1988, the surgeon general, C. Everett Koop, proclaimed ice cream to a threat to public health is to the height of the cigarettes. in allusion to the famous report of its office 1964 on the dangers of smoking, Dr. Koop announced that the American diet was a problem of magnitude “comparable”, mainly due to high food . fat that were causing coronary heart disease and other deadly diseases presented his report with these words: “. The depth of the science base underlying its findings is even more impressive than snuff and health in 1964 “
In the case of fatty foods, which trusts the voice belonged to Ancel Keys, a prominent researcher diet half a century ago (it was said that the K rations in World War that his name carries). he became convinced in the 1950s that Americans were suffering from a new epidemic of heart disease because they ate more fat than their ancestors.
there were two obvious problems with this theory, as Mr. Taubes, a correspondent for Science magazine, explains his book. first, it is not clear that traditional diets were especially lean. nineteenth-century Americans consumed large quantities of meat. the percentage of fat in the diet of ancient hunter-gatherers, according to the current best estimate it was as high or higher than the ratio in the modern Western diet.Second, there was not really a new epidemic of heart disease. Yes, they are reporting more cases, but not because people were in worse health. It was mainly because they were living longer and were more likely to see a doctor who diagnosed the symptoms.
to bolster his theory, Dr. Keys in 1953 compared diets and rates of heart disease in the United States, Japan and four other countries. Indeed, more fat correlated with more disease (America tops the list). But critics of the time said that if Dr. Keys had analyzed all 22 countries for which data are available, would not have found a correlation. (And, as Mr. Taubes points out, no one would have puzzled about the so-called French paradox gras connoisseurs with healthy hearts.)
The evidence that dietary fat correlates with heart disease ‘ does not stand up to critical scrutiny, the American Heart Association concluded in 1957. However, three years later, the association changed position – not because of the new data, Mr. Taubes writes, but because Dr. Keys and an ally were on the committee issuing the new report. It was stated that “the best evidence of the time ‘justifies a low-fat diet for people at high risk of heart disease.”
Why low fat is killing you
1. Low Fat High often means sugar
to make foods low in fat or fat-free food companies turn to further processing, the addition of chemicals and fat substitutes to keep the textures and flavors like the original product. These additives (gums, inulin, maltodextrin, plydestrose, starch, modified starch) are fat substitutes based on carbohydrates. In many cases, a fancy name for sugar.
2. It can lead to cardiovascular problems
Did you know that high levels of high-density lipoprotein ( “good” cholesterol) is associated with a lower risk of disease from the heart? Whereas, a diet low in fat leads to reductions in HDL, cany leading to increased risk of heart disease.
In a 2004 editorial in the Journal of American College of Cardiology, Sylvan Lee Weinberg, former president of the American College of Cardiology and outspoken proponent of the hypothesis of the diet-heart, he said:
the low-fat, high-carbohydrate diet … may well have played an unintended role in the current epidemic of obesity, dyslipidemia, type 2 diabetes and metabolic syndrome. This diet can no longer defend themselves by appealing to the authority of prestigious medical organizations.
3. Produce hormonal imbalances
Did you know that many of the most important hormones are made from cholesterol? Cholesterol is required for normal cell function and brain function; to strengthen your immune system and build brain and nerve tissue.
4. It causes weight gain
Health Initiative of Women, the largest clinical trial of diet and body weight, found that 50,000 women in low-fat diets had no significant weight loss and no differences between those who followed low-fat, low carb, and very- diets low in carbohydrates. In fact, most low-fat foods such as margarine, skim milk and other low-fat products are loaded with calories, carbohydrates, sugar and processed flour that lead to weight gain.
5. It can cause depression and anxiety
Most of our cells are made up of cholesterol, and more than 60% of the brain is composed of fat. Therefore, if you are not eating the right kind of fat, you are damaging your brain.
Sarah Conklin, PhD, a postdoctoral researcher at the Cardiovascular Behavioral Medicine, Department of Psychiatry, University of Pittsburgh presented a study that found that low levels of EPA and DHA are related to the deterioration of the state of spirit.
We were able to show that people who consumed more omega-3 in their diets had the volume of gray matter in areas important for mood regulation brain. These results suggest that these specific fats, certainly not fat, in general, may confer a protective effect against depression and other problems related to mood.
