Nutrition, Fourth Edition is an up-to-date, accessible introduction to nutritional concepts, guidelines, and functions. This text provides students with accurate, scientifically based information on topics and issues that concern them--a balanced diet, weight management, and more--and encourages them to think about the material they#146;re reading and how it relates to their own lives. The MyPlate Update integrates the latest nutritional standards -- the new Dietary Reference Intakes, the 2010 Dietary Guidelines, and MyPlate (which replaces the former MyPyramid) -- right within the book, providing instructors and students with the most current information available.
