Rockville, MD - "The influence of dietary fats on serum cholesterol has been overstated," concludes a review in an American Society for Nutrition publication that, in its words, "calls for a rational reevaluation of existing dietary recommendations that focus on minimizing dietary [saturated fatty acids] SFAs, for which mechanisms for adverse health effects are lacking". Indeed, argues the author, Dr Glen D Lawrence (Long Island University, Brooklyn, NY), it is likely other factors, such as oxidized polyunsaturated fatty acids (PUFAs) or preservatives in processed meats, that are also present in high-SFA foods that lead to adverse health effects typically associated with high SFA intake. "The meager effect that saturated fats have on serum cholesterol levels when modest but adequate amounts of polyunsaturated oils are included in the diet, and the lack of any clear evidence that saturated fats are promoting any of the conditions that can be attributed to PUFA, makes one wonder how saturated fats got such a bad reputation in the health literature," Lawrence writes in the review, published May 1, 2013 in Advances in Nutrition.
