Excerpt from Gary Taubes’ Article: “What if It’s All Been a Big Fat Lie?”

The Truth about Saturated Fats and Heart Disease

The demonization of saturated fat began in 1953, when Dr. Ancel Keys published a paper comparing saturated fat intake and heart disease mortality. His theory turned out to be flimsy, to say the least, but the misguided ousting of saturated fat has continued unabated ever since.

Keys based his theory on a study of 7 countries, in which higher saturated fat intake equated to higher rates of heart disease. However, he conveniently ignored data from 15 other countries that did not fit his theory. Had he chosen a different set of countries, the data would have shown that increasing the percent of calories from fat reduces the number of deaths from coronary heart disease.

When you include all 22 countries for which data was available at the time of his study, you find that those who consume the highest percentage of saturated fat have the lowest risk of heart disease.

The nutrition community of that time completely accepted Keys’ hypothesis, and encouraged the public to cut out butter, red meat, animal fats, eggs, dairy and other “artery-clogging” fats from their diets – a radical change at that time that is still very much in force today. Most of the experts I know believe that Dr. Keys’ research was pivotal for perpetuating the flawed low-fat approach to health. This is a major part of the solid science you will need to know if anyone seeks to disagree with you when you share this information; this study is really the foundation that triggered the massive emphasis on low-fat diets and the flawed belief that cholesterol and animal fats are so pernicious.
