The 1990s were the height of the low-fat diet craze, exemplifed by the original Food Guide Pyramid, published in 1992 (see fgure on page 4). Based on the notion that all calories are alike, the pyramid advised us to avoid all types of fat because they contain twice the calories of other major nutrients. Instead, we were told to load up on carbohydrates, including six to eleven servings each day of bread, cereal, crackers, pasta, and other grain products. Luckily, I hadn’t been indoctrinated in these conventional teachings and began my career in research and patient care with an open (and mostly empty) mind when it came to nutrition.
