The Omnivore's Dilemma by Michael Pollan
Recommended by Libby V:
This book has turned vegetarians into omnivores and omnivores into vegetarians. I’ve been a vegetarian for 10+ years and this book reaffirmed that decision for me, but it’s full of purely objective information. It covers the full spectrum of possibilities of where our food can come from and changed my eating habits from unhealthy, processed food vegetarian to healthy, local food-eating vegetarian. Changed my life.
