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'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.
