In my new book, THE DORITO EFFECT, I examine the food crisis -- obesity, metabolic disease, etc., through the lens of flavor. For 50 years, we've been arguing over fat, carbs and sugar. Does the way food taste have something to do with how much people eat? I think the answer will surprise, frighten, and thrill you. My first book, which came out in 2010, was STEAK, in which I traveled the world searching for the single greatest piece of meat.
