Omnivore's Dilemma

So I started reading The Omnivore's Dilemma the other day. I really love the way Michael Pollan has structured the book around three different food chains, the industrial, the organic, and one that is entirley local. i'm still in the industrial food chain right now, and he covers a lot of the same ground that Katz covered in Underground Food Movements. It still shocks and appalls me how much corn we really eat. Its everywhere and in almost anything. I don't know if anyone saw the movie 'The Informant' with Matt Damon, but his character works for Archer Daniels-Midland and he jokes and quizzes his son about the prevalence of corn in so much of our food. We really are trapped in this maze where we have no idea where our food comes from (beyond "the grocery store." it saddens me when I try to encourage others to buy local or to at least be more aware of what they are eating and they just shrug their shoulders and eat another McNugget.
