  • UPDATED HIGHLIGHTS: Each chapter is followed by a timely "Highlight" section offering an in-depth look at a current--and often controversial--topic that relates to chapter concepts. Questions at the end of each Highlight help readers develop clear, rational, open-minded and informed thoughts based on the evidence presented in the text--critical-thinking skills that will serve them well beyond the course.

  • THE LATEST RESEARCH: Continuing a tradition of cutting-edge coverage, the 15th Edition of UNDERSTANDING NUTRITION has been thoroughly revised and updated with the most current research available, as well as emerging trends, issues and developments from the field.

  • NEW GUIDELINES: Content and tables throughout have been updated to reflect the 2015-2020 Dietary Guidelines.

  • HANDS-ON PRACTICE: Integrated throughout the text, "How To" tasks develop readers' problem-solving and other practical skills, such as calculating energy intake from carbohydrate, fat and protein. A "Try It" activity following each section gives students plenty of practice sharpening their skills.

  • COMPLETE AND RELEVANT: UNDERSTANDING NUTRITION, 15th Edition, begins by introducing the nutrients and thoroughly explaining their work in the body, while later chapters equip students to apply that information to their own and other people's lives.

  • EMPHASIS ON KEY CONCEPTS: Chapters open with Learning Objectives to help students immediately focus on important concepts. Each learning objective is tied to a "Learn It" section and reinforced with end-of-chapter "Review It" sections.

  • QUICK REFERENCE TABLES: Equipping students with a fast but thorough reference, up-to-date tables throughout the text include the USDA Healthy Mediterranean Eating Pattern, 2015-2020 Dietary Guidelines, carbohydrate recommendations for physical activities and much more.

  • WEIGHT LOSS: Information to support this always-relevant topic includes up-to-date tables for ghrelin and leptin and SMART goals, recent FDA-approved weight loss drugs, discussions of medical procedures to treat obesity and updated map illustrations showing the prevalence of obesity among U.S. adults.

  • FITNESS FACTS: In addition to thorough coverage of general fitness, UNDERSTANDING NUTRITION, 15th Edition, includes updated protein recommendations for athletes and a table of food sources, a discussion of dietary nitrate as an ergogenic aid, a section on glucose use during physical activity and other weighty matters.
