Eat food, not too much, mostly plants

Michael Pollan is not a vegetarian. He is however a journalist who has written some powerful pieces that explore, and support, the vegetarian argument.
In his January 2007 New York Times article, Unhappy Meals he uses nearly a dozen pages to prove his opening thesis that we'd all be better off if we ate "food" (real food - apples, not apple derivatives), and only a little bit, and stayed as far away from meat as possible.
His 2006 book The Omnivore's Dilemma examined the different types of meals available to North Americans - a fast food meal vs. an "organic meal" vs. a completely self grown & cooked meal. It was at it's most powerful when examining the factory farming system, and part of this can be read here.

Really interesting reading, especially if you haven't given much thought to food issues & and industrial agriculture before, and want to be introduced to the field by a fairly neutral, but very critical, omnivore.
