Beschreibung

A new book in the acclaimed Nutrition Society Textbook Series, Nutrition Research Methodologies addresses the rapidly advancing field of nutrition research. It covers the diverse methodologies required for robust nutritional research to ensure thorough understanding of key concepts, both for students at undergraduate and postgraduate levels and for scientists working in nutrition research.

Combining theory with practical application, Nutrition Research Methodologies addresses both traditional research methods and new technologies, and focuses on a range of complex topics, including energy compensation, nutrient-gene interactions and metabolic adaptation. It also considers statistical issues as well as application of data to policy development.

• Provides the reader with the required scientific basics of nutrition research in the context of a systems and health approach
• Written specifically to meet the needs of individuals involved in nutrition research
• Combines the viewpoints of world-leading nutrition experts from academia and research with practical applications
• Accompanied by a companion website with a range of self-assessment material (www.wiley.com/go/lovegrove/nutritionresearch)
