Book summary

Rick Gallop's simple, user-friendly guide to healthier eating divides food into three groups that correspond to traffic-light colors--red for stop (don't eat), green for go (eat), and yellow for caution. The ratings are based on the Glycemic Index, which was a basis for the Zone Diet. Gallop encourages readers to eat low-G.I. and low-carb meals, and the red-yellow-green format is useful for those who need reminders that some foods really are "bad" and are to be avoided. Readers who want to eat better find more choices for meals, snacks, and shopping. Gallop also includes what he calls "meal ideas" which consist of a variety of approaches to the same ingredient.
