Compulsion and complexity in food

When I was first becoming a foodie in college I decided to switch my major to food science. I registered for most of the required basic science courses, as well as the intro class for majors. Unfortunately that class is why I'm not a food scientist. It was taught by a former head food scientist from Kraft and you could have retitled it "how to sell massive and ever increasing amounts of garbage commodity foods to Americans." I remember in one lab we toured they were making crispy puffs out of some soy byproduct that they told us would otherwise go to waste.
