Nutrition addresses the most hotly debated topics in the news today: obesity, food safety, irradiation, and vegetarianism and also describes the currently accepted principles of good nutrition for men, women, and children.Despite the abundance of advice on food and diet, more Americans are obese than ever before, diabetes rates are skyrocketing, and more foods are recalled due to contamination. It is high-time for non-biased answers to the question of what is healthy and safe to eat. Nutrition provides those answers. The book explains basic guidelines for healthy eating, along with the government's role in nutrition. It examines the issues of food safety and technology and the debates about genetically modified foods, organic foods, and vegetarian dining. Food bans, such as those on transfats are discussed, as are vitamins and supplements. After tracing the history of the study of nutrition and identifying principal researchers, the book examines seven major controversies in nutrition today. This basic guide to healthy eating will give both students and adults the tools they need to choose a diet that is healthy and safe.
