I've been telling everyone around me that corn/soy are in almost all of our processed products today. Food Inc. also touched on the obscene amount of corn and soy that are being grown in America today. What's funny and what I don't understand sometimes is they use corn, soy and other high carbohydrate feeds to fatten up the livestock so they produce more meat but, turn around and say a high carb diet is healthy for us and will make us skinnier. People don't really pay attention do they haha.
Also, to add, they seem to have taken the full movie off of youtube.
