Man, the medical establishment can drive one nuts. Check out the results of an 8 year study on the effects of a low-fat diet in this article in the New York Times. The answer? Not much at all in terms of the incidence of heart disease and various cancers between the women on the diet and the ones who were not. This is apparently one of the most comprehensive studies of this nature ever conducted, and the results have thrown things into confusion for dietitian and physicians trying to advise their patients, including folks like me. The article is well worth a look for anyone interested in healthy eating.
