Food for thought:
That the official embrace of low-fat, high-carbohydrate diets coincided not with a national decline in weight but with epidemics of both obesity and diabetes (both of which increase heart disease risk), should make any reasonable person question the underlying assumptions of the advice. But that’s not how people tend to think when confronted with evidence that one of their long-held beliefs is wrong. It’s not how we typically deal with cognitive dissonance. It’s certainly not how institutions and governments do it.
From Why We Get Fat (Amazon.com, Amazon UK) by Gary Taubes. This book explains why eating fat doesn’t make us fat, but eating carbohydrates does. Why we don’t get fat because we eat, but we eat because we’re getting fat. Fascinating stuff.
