For decades, nutritionists have advocated a diet low in fat. But investigative journalist Nina Teicholz says that recommendation is based on a single, faulty study. In her book "The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet," Teicholz says America's obsession with diets low in fat and high in carbohydrates has actually made us fatter and less healthy. Teicholz is a former NPR reporter and has written for The New Yorker, The Economist and The New York Times.
