Food Rules is a small book with short, concise yet simple rules to help you stay on your road to a healthy body and planet. All super rules. Like Rule 20; it's not food if it arrived through the window of your car. Or Rule 57; don't get your fuel from the same place your car does. I love that one. Each rule has a brief paragraph explaining the rule. I not only recommend the book to you but I have purchased several as gifts for friends
