I'm taking a Sociology of Food class this semester which has covered most of these. We've had to read a pretty diverse amount of material. One thing covered though was excerpts from Marion Nestle books. In the readings she details instances of various members of the Food Industry influencing policy as well as general guidelines for health and nutrition published by the government, which have in turn influenced the public opinion on what's considered a healthy diet. If anyone is interested I can compile the readings into on PDF and post it later on when I get home.
I'd totally be into that, but I understand if you don't just want to compile your readings into a PDF for one person.
Here you go dude, I just included all the course reading. The "textbook" is omnivores dilemma with the other pdf's filling in gaps the books leaves. The word document is the order in which we've been reading things in class. The articles in particular I mentioned are (4) and (5). Hope you enjoy it.
