The article discusses the U.S. movement to eat a low-fat diet. Topics include flawed research by physiologist Ancel Keys suggesting that fat raised cholesterol levels, causing heart disease, research since the 1980s indicating a tenuous link between saturated fat and heart disease by multiple teams, including epidemiologist Rajiv Chowdhury, cardiologist Ronald Krauss and physician Dean Ornish and the conclusion that small LDL-cholesterol may be affected by carbohydrates rather than fat.
