My friends don't want to read this book because they see how it changed my eating habits. It's been a while since I've read it, and truthfully, I've gone back to some of my old habits. What you take from this book is knowledge about where your food comes from, who grows it, who engineers it, and what effect this all has on our health, our country, and the environment. 
 This book is similar to Omnivore's Dilema and In Defense of Food, although it concentrates more on the fast food machine.
