The papers highlight a number of novel techniques that are currently used in nutritional research, including the doubly labeled water method; the labeled bicarbonate method; X-ray computed tomography; neutron activation analysis; magnetic resonance imaging; and the application of stable isotope tracers. Divided into four sections encompassing 20 chapters, this volume begins with an overview of stable isotopes and their applications in nutrition science, including vitamin research, and in the investigation of mineral metabolism. It then discusses modern approaches for measuring energy expenditure and body composition, classical and modern methods of anthropometry, measurement of bone mineral content in vivo, and imaging techniques in analysis of bone status. Nutritional scientists will find this book a useful source of information related to the field.
