The Stress Biology & Nutrition Research Initiative is one of the first of its kind created to facilitate innovative research bridging nutrition, agriculture, stress biology, and psychological health.
Controlled-feeding studies give USDA researchers insight into the health effects of the macro and micro-nutrient composition of our daily diets.
Indirect and whole-room calorimetry studies allow USDA researchers to better understand the bio-energetic pathways that our bodies use to process the energy from food, giving us insight into weight loss and weight gain.
To conduct nutrition interventions, that contribute to dietary and physical activity recommendations that will prevent obesity and related metabolic disorders such as diabetes and cardiovascular disease, to conduct vitamin and mineral interventions to improve human health and function, and to conduct nutritional phenotyping studies to better understand the cause and impact of inter-individual variability in response to such interventions. Factors studied include, but are not limited to, diet patterns, a variety of specific foods, different types and amounts of carbohydrates including non-digestible carbohydrates and simple sugars, lipids, vitamins, minerals and stress. In human subjects and cell and animal models, state-of-the-art methods including omics technologies are used to study the effects and mechanisms of action of the nutrition interventions on: whole body, tissue and cell metabolism; body weight and composition; markers of risk of chronic disease; food intake behaviors; endocrinology; nutrient kinetics and absorption; gut microbiome population and function.
