Move students beyond memorization with a functional approach to nutrition

The Science of Nutrition  helps students master tough nutrition concepts while providing rich support to save instructors time. This best-selling, thoroughly current, research-based nutrition text is uniquely organized around the highly regarded functional approach, which organizes vitamins and minerals based on their functions within the body and is easily seen in the organization of the micronutrient (vitamin and mineral) chapters.


The 5th Edition includes the most up-to-date scientific research in the field of nutrition, an increased emphasis on nutrition and disease content, and new icons in the margins directing students to Oregon State University’s FoodHero.org. The text covers key concepts in nutrition with new and updated Focus Figures; updated Nutri-Case case studies; and Nutrition Concept Videos, which feature author Janice Thompson explaining difficult course concepts. Additionally, instructors can assign updated NutriTool activities and autogradable  MyDietAnalysis Personalized Dietary Analysis activities in Mastering Nutrition  


Also available as a Pearson eText or packaged with Mastering Nutrition:


Pearson eText is a simple-to-use, mobile-optimized, personalized reading experience that can be adopted on its own as the main course material. It lets students highlight, take notes, and review key vocabulary all in one place, even when offline. Seamlessly integrated videos and other rich media engage students and give them access to the help they need, when they need it. Educators can easily share their own notes with students so they see the connection between their eText and what they learn in class – motivating them to keep reading, and keep learning.

If your instructor has assigned Pearson eText as your main course material, search for:

013537152X / 9780135371527 Pearson eText The Science of Nutrition -- Access Card, 8/e
