I really enjoyed this book! Easy and fast to read, the book is written tongue-in-cheek by Michael Pollan. It's one that a family could pass around and everyone could read in a day. More white space than print, but don't be fooled:
The print is powerful!
You can find used copies on Ebay for less than $10, total. Newer versions have delightful artwork. Once you read it, the book becomes part of you, so you can pass it on. You won't forget what you read. Follow what it says, and you'll eat better and feel better for it.
