Understanding Nutrition

COMPLETE AND RELEVANT: The new edition begins by introducing the nutrients and thoroughly explaining their work in the body. Later chapters equip students to apply that information to their own and other people's lives—describing the role of foods and nutrients in energy balance, body weight, physical activity, disease prevention, food safety, hunger, and in the overall life cycle.

EMPHASIS ON KEY CONCEPTS: Chapters open with Chapter Outlines & Learning Objectives to help the reader immediately focus on important concepts. Each learning objective is tied to a section that closes with a Review.

HANDS-ON PRACTICE: Many chapters include "How To" features that guide readers through problem-solving tasks. New to this edition is the "How To" feature in Chapter 1 detailing how to Calculate the Acceptable Macronutrient Distribution Range (AMDR) in Grams and in kCalories. Each “How To” feature ends with a "Try It" activity that gives students an opportunity to practice these new lessons.

NEW GUIDELINES: All text, tables, and figures have been updated to reflect current food labels: the 2020-2025 Dietary Guidelines, Healthy People 2030, 2019 Choose Your Foods, and the 2018 edition of the Physical Activity Guidelines for Americans.

NEW HIGHLIGHT: Highlight 2 expands its presentation of vegetarian diets and shifts its focus to include the many benefits of plant-based diets.

THE LATEST RESEARCH: Continuing a tradition of cutting-edge coverage, the 16th Edition has been thoroughly revised and updated to reflect current research and emerging trends.

UPDATED HIGHLIGHTS: Every chapter is followed by a Highlight that provides an in-depth look at a current, and often controversial, topic that relates to its companion chapter. Each Highlight closes with Critical Thinking Questions to encourage readers to develop a clear, rational, open-minded, and informed understanding based on the evidence presented in the text.
