Grades 4-5. Food Chemistry offers a comprehensive overview of how food influences our health. Students learn about balanced diets by exploring the differences among carbohydrates, protein, and fats; the interaction between food and the body through digestion; and special diets. One story discusses what astronauts eat while they spend long stretches of time in space, why astronauts' food is packaged as it is, and how the space program has influenced our daily diet. The book also includes healthy seafood recipes collected and published by Smithsonian scientists.
