Book excerpt: While written from a nutritional sciences perspective, Advanced Nutrition and Regulation of Metabolism is a reference source that emphasizes regulation of proteins and gene expression. The focus is on the function of nutrients, how function relates to deficiency and its symptoms, how both of these relate to assessment, and how this is achieved during the fed-fasted cycle. After reviewing cell biology and basic biological concepts, the book discusses digestion and absorption, carbohydrates, lipids, proteins, water-soluble vitamins, fat-soluble vitamins, and minerals. Students learn how these are all structured and absorbed, become familiar with the nomenclature, and study their impact on metabolism, as well as other essential biological functions. Each chapter includes specific objectives and outcomes to guide student learning, reflection, discussion, comprehension questions, and an application opportunity. Designed for students who are already familiar with introductory and intermediate nutritional sciences, Advanced Nutrition and Regulation of Metabolism assumes that readers have a background in cell biology, biochemistry, and physiology. The book is well-suited to advanced nutritional sciences courses, as well as some classes in animal science, kinesiology, genetics, and biochemistry.
