New thinking on saturated fat
Back in 1957, the American Heart Association (AHA) proffered its first guidelines for a heart-healthy diet. In a nutshell, the AHA said that diet may influence heart disease, that both the fat content and total calories in a person's diet were important, and that people should consume less saturated fat and more unsaturated fat. By the late 1960s, though, the message morphed into "fat is bad."
What we know today is that dietary fats fall on a spectrum, with trans fats on the "avoid completely" end, saturated fats in the "go easy" middle, and unsaturated fats on the "emphasize" end. Until trans fat slid onto the public health radar, saturated fat was the poster child for "bad" fats. Analyses brush a bit of the tarnish off its sinister reputation.
