The Omnivore's Dilemma: A Natural History of Four Meals

Author: Michael Pollan

I enjoyed this book. It takes an incredibly complex subject (namely, our industrial food complex which is a mysterious black box to most people) and attempts to explain it and personalize it and talk about how what we do on a daily basis affects the economy, the environment, our health, etc. And after finishing it, I swore to never eat "industrial" beef ever again. And for two weeks I didn't have McDonalds. That's pretty good.

In summary: "Eat food, not a lot, mostly plants".
