By Dr. George Goodheart

Summary: In 1961 the American Heart Association (AHA) officially endorsed the “diet-heart hypothesis,” the idea that overconsumption of dietary fat increases the risk of heart attack. In particular the AHA condemned saturated fat, a type of fat found primarily in animal foods. Holistic health practitioners balked at the idea of this natural substance causing an unnatural condition such as heart disease and sensibly claimed that, if anything, synthetic fats such as hydrogenated fats and heat-processed plant oils—introduced just prior to the rise of the heart disease epidemic—were likely to blame. These natural healers proved to be prescient, as research in recent decades has shown a correlation between the consumption of hydrogenated fats and heart disease while failing to show such a connection for natural saturated fat. (Ironically, many of the early studies “supporting” the diet-heart hypothesis lumped hydrogenated fats and saturated fat into the same category.) In this article from 1965, famed chiropractor Dr. George Goodheart dispels myths about the diet-heart hypothesis—including the idea that cholesterol is a toxin—and explains why natural fats actually aid proper cholesterol metabolism, not hinder it. He goes on to suggest that overconsumption of refined carbohydrates, not natural fat, is likely the biggest dietary cause of heart disease—a hypothesis explored in scientific detail in the seminal 2007 book Good Calories Bad Calories.
