The 10-volume "Health Facts" series is intended to supplement to health education curricula and provide a handy reference for individuals who would like additional background information on particular health topics. The emphasis is on topics and examples relevant to youth of middle and high school age. The five sections in this book provide teachers with basic facts about: the types and components of food; the most recent guidelines for eating a healthy diet; the association between diet and disease; the relationship between body image and weight control; and special dietary issues associated with exercise and sports. An easy to read reference format offers clear, concise data intended to familiarize educators with the most important facts about the issues and concerns. A glossary, a list of resources, and 20 references complete the volume. (LL)
