Don't fear fat. Eating saturated fat will not make you fat. Eating refined carbs will.
An article published in "Advances in Nutrition" this year calls for re-evaluation of current recommendations which suggest reduction of saturated fats in diet. Framingham Heart Study showed that hypercholesterolemia is a major risk factor for coronary artery diease (CAD). Other studies showed high saturated fat diet led to high serum cholesterol levels. These two findings led to the widely-accepted concept that high saturated fat diets increase the risk of CAD. Recent data revealed that the relation between saturated fat content and CAD incidence is weak. Several recent analyses indicate that saturated fats, particularly in dairy products and coconut oil, can improve health. The evidence of n-6 polyunsaturated fatty acids (PUFAs) promoting inflammation and augmenting many diseases continues to grow, whereas n-3 PUFAs seem to counter these adverse effects. Patients should be advised to minimize their intake of n-6 oils when attempting n-3 supplementation as a therapeutic approach to reduce the inflammation of arthritis and other inflammatory syndromes. Because dietary saturated fats do not promote inflammation, it may be wiser to minimize n-6 PUFAs and consume more saturated fats to reduce various types of inflammation. The replacement of saturated fats in the diet with carbohydrates, especially sugars, has resulted in increased obesity and its associated health complications. The metabolism of cholesterol and pathogenesis of CAD are indeed extremely complex and the fat phobia dogma makes the problem even harder to solve. It is time health care professionals update their knowledge about fat, so that the general public would have the right direction to follow in the current obesity epidemic.
