The dietary theory of fat avoidance probably began with the United States Senate Select Committee On Nutrition And Human Needs (1968-1977). This committee created “Dietary goals for the United States” in 1977. A main feature of those dietary goals was to reduce the fat in the diet.
There is little doubt that that Senate Select Committee depended on a famous fat study known as the Seven Countries Study, which began in 1956. This study was carried out by Ancel Keys, Ph.D. Of interest, this study studied included 22 countries. Apparently, only seven of the countries met Dr. Keys preconceived notions. Dr. Keys designed this study to show that as dietary, saturated fat consumption increases, so does cardiac disease.
Another famous anti-fat study was known at The China Study (2005). This study was spearheaded by Colin Campbell, Ph.D. Dr. Campbell designed this study to demonstrate that increased meat and dairy consumption caused increased heart disease.
The concept of low fat diets being advantageous should have been resoundingly defeated following the Women’s Health Initiative (1991-2006). This study was better designed than the Seven Countries Study or The China Study. It involved 50,000 women. This study clearly demonstrated that low fat diets have absolutely no health benefits.
In my opinion, low-fat diets gave Americans an epidemic of obesity, heart disease, diabetes, and the rest of the Western Diseases.
Utilizing the principles outlined in Chapter 3, this outcome from the Women’s Health Initiative could have been predicted utilizing known facts of physiology, biochemistry and nutrition. Please understand that a low fat diet almost necessarily translates into a high carbohydrate diet.
To reiterate, fat in the diet does not cause disease. Saturated fats, meaning fatty acids with double bonds between adjacent carbon atoms, have been demonized. Saturated fats are found in meat and cheese. There is no association between saturated fats and coronary artery disease (heart attacks), cerebrovascular accidents (strokes) or dyslipidemia (increased cholesterol, low HDL, high IDL, etc.).
Fat is an essential fuel for many cells of the body. In fact, when not exercising, fat is the primary fuel for muscles and the heart.
As alluded to earlier, there are essential fats. That means that we must take in these fats in the diet, as we cannot create these fats on our own. These include omega 3 fatty acids and omega 6 fatty acids. Our body needs a combination of omega 3 and omega 6 fatty acids to :function optimally. Unfortunately, most of us have a diet much richer in omega 6 fatty acids, creating an imbalance between omega 3 and omega 6 fatty acids.
