Nina Teicholz's letter to NYTimes: Let’s Re-examine the Science of Dietary Fats
Let’s Re-examine the Science of Dietary Fats

To the Editor:
“Why Diets Are Such a Mystery,” by David S. Ludwig and Steven B. Heymsfield (Op-Ed, Nov. 14), rightly highlights the lack of funding for diet trials and notes that a dearth of such data may inhibit work by the expert committee currently reviewing the science for the next Dietary Guidelines for Americans.
In fact, many large, government-funded trials have been conducted but ignored, by all successive expert committees, since the guidelines’ launch in 1980.
Most critically, no committee has ever directly reviewed the trials on saturated fats, on more than 25,000 trial participants in experiments lasting up to 12 years. These experiments conclusively demonstrated that when people replaced saturated fats with polyunsaturated vegetable oils (swapping butter for margarine, for instance), there was no reduction in cardiovascular or total mortality.
These major trials, which are the most rigorous evidence available on these fats, have been analyzed in 17 different reviews, concluding over all that there is little to no support for the government’s continued caps on saturated fats.
Thus, while we wait for new funds for new diet trials, let’s use the data we do have to provide science-based advice to the public.
