Abstract: This monograph presents a no-nonsense approach to nutrition and abolishes the nutritional "magic" of oversimplified advice, baseless food fears, and false hopes. It shows how proper diet can help one live a healthier, more active and more productive life. Discussions are on how one can analyze his/her diet according to the latest findings on food content and recommended daily allowances. Most of the current data about specific nutrients, metabolism, digesion, weight control, modern nutritional def iciencies, and the role of nutrition in disease are discussed. Information is tailored to specific life stages, health concerns, and levels of physical activity. Appendices are included.
