Clinical & Epidemiological Nutrition Research
Clinical and epidemiological research in nutrition.
The Clinical and Epidemiological Nutrition Research program supports clinical research focused on observational/interventional studies in nutrition, as well as nutritional epidemiology studies. This program includes clinical studies examining the effects of nutrient or dietary intake, diet composition, diet intervals, variation in nutritional status, or interventions ranging from, but not limited to, whole foods/dietary patterns, dietary supplements, or alternative delivery modes (i.e., parenteral or enteral nutrition) on health-related outcomes in humans. Nutrients may encompass macronutrients, vitamins/minerals, phytonutrients, and other food components. Clinical studies of nutritional status or interventions from infancy throughout the aging process are of interest. The program serves as a focal point for the collection, analysis, and dissemination of data on nutritional intake, status, and disorders of public health significance, with particular emphasis on national/global surveillance and follow-up studies. This program also includes policy- and population-based approaches to improving nutrient/dietary intake or nutritional status not focused on obesity/weight control. Other relevant research projects would include methodologies to improve assessment of nutrient intake and/or status in humans throughout the lifespan.
The Clinical and Epidemiological Nutrition Research program does not support research regarding obesity, energy balance, or weight control. For obesity research, please see Obesity Treatment and Prevention or Clinical, Behavioral, and Epidemiological Obesity Research. For research related to nutrient requirements and metabolism, see Nutrient Metabolism, Status, and Assessment.
