Gr 6-10-Each chapter in this informative presentation consists of about 20 questions and answers plus an article on a related topic. Queries (printed in red type) are generally answered in a few paragraphs but responses to a number of questions are longer. Metabolism, carbohydrates, fats, proteins, vitamins, minerals, cholesterol, fiber, fast food, milk, vegetarianism, vegetables, unusual eating behaviors, nutritional diseases, cancer, organic food, fluoride, and world hunger are among the topics covered. Black-and-white charts, diagrams, and photos complement the text. Readers will find diagrams of the hydrolysis process, the human digestion system, Type 2 diabetes, and sigmoidoscopy and colonoscopy procedures. Charts note the energy density of selected foods, sources of sugar in the American diet, and the pros and cons of the genetic modification. Back matter includes tables of vitamins and minerals, nutritional deficiency diseases, and some herbal supplements. Despite a few typographical/and or spelling errors, this is a fine addition to most collections.-Augusta R. Malvagno, Queens Borough Public Library, NY Copyright 2003 Reed Business Information.
