The Nutrition Obesity Research Center (NORC), formerly the Clinical Nutrition Research Unit (CNRU), is designed to promote and enhance the interdisciplinary nutrition and obesity research activities at the University of Washington. By providing a number of Core Facilities, the NORC facilitates the integration and coordination of the abundant ongoing activities throughout the UW system. Our overarching goals are to foster new interdisciplinary research collaborations, stimulate new research activities, improve nutrition and obesity education at multiple levels, and facilitate optimal nutritional management of patients. Core facilities are available for use by Affiliate Investigators, who are broadly dispersed throughout several schools and numerous departments and divisions within the University of Washington. The University of Washington NORC is supported by the National Institutes of Health, NIDDK, grant # P30 DK035816.
