In The Omnivore's Dilemma, Michael Pollan writes about how our food is grown -- what it is, in fact, that we are eating. The book is really three in one: The first section discusses industrial farming; the second, organic food, both as big business and on a relatively small farm; and the third, what it is like to hunt and gather food for oneself. And each section culminates in a meal -- a cheeseburger and fries from McDonald's; roast chicken, vegetables and a salad from Whole Foods; and grilled chicken, corn and a chocolate soufflé (made with fresh eggs) from a sustainable farm; and, finally, mushrooms and pork, foraged from the wild.
