Ancel Keys did a study titled the Seven Countries Study in 1955 where he presented his hypothesis, diets low in animal fat protected against heart disease and that a diet high in animal fats led to heart disease. Keys started with twenty-two countries and selected seven. The fifteen he excluded include France and West Germany, countries with high-fat diets and low heart disease rates. They contradicted the hypothesis so they weren't in the study. This study became the definitive citation in official dietary recommendations for the next forty years, telling people to avoid saturated fat. We're still living in the aftermath. Low-fat everything. Seed oils. A food pyramid built on omissions and lies.
