But that evidence simply isn't there. For example, in the breast cancer study, incidence rates between the intervention and comparison group did not show a statistically significant difference, meaning that any differences between words the groups were indistinguishable from chance. Similarly, in the cardiovascular disease study, the "diet had no significant effects on incidence of CHD (coronary heart disease), words ... stroke ... words or CVD (cardiovascular disease)." So whatever the hype about these studies showing "trends" toward the benefits of low-fat diets, the scientific results do not support those claims. What's difficult to know is just which bit of the story about the new studies is most extraordinary. Is it the fact that the advice provided to Americans to eat diets low in fat in order to reduce the risk of heart disease and cancer is not supported by current science?
