Our productivity is measured in part by the number of publications arising from studies that use GCRC resources. If your study is supported by the GCRC, we rely on you to cite our grant in your publications. Don't forget to send us a reprint too! (via email or campus mail, Box 356178). Thank you!

Nutrition Studies

For Constant Diet or Controlled-Nutrient Feeding Studies

The Nutrition Research Core of the UW GCRC includes the university's only fully-equipped research kitchen, as well as an adjacent office for one full-time nutrition research manager and research dietitian. The nutrition research kitchen is staffed by three full-time research dietetic technicians, who create and test recipes for research diets and prepare the food for feeding studies. All food items are weighed on precision electronic scales to ensure the nutrient content as determined using ProNutra software. Returned food is weighed on a balance connected directly to ProNESSY software that allows correction for items not consumed.

Subjects meet with GCRC research dietitians for screening and explanation of the dietary requirements, nutrition assessment, and determination of food preferences and energy requirements. Subject compliance is monitored by the nutrition research staff.

Outpatients

Outpatients pick up meals at the research kitchen and receive instruction on dietary compliance and safe food handling practices by the research dietetic technicians.

Inpatients

Inpatients are accommodated in patient rooms located on the UW GCRC unit.

For Dietary Intake Analysis utilizing 3-day Food Records

The Nutrition Research Core of the UW GCRC is staffed by an experienced nutrition research manager, research dietitian and three research dietetic technicians. They instruct subjects on the collection of 3-day food records, clarify the returned records, and analyze the dietary intake using University of Minnesota Nutrient Data System for Research (NDS-R) software. The nutrition research manager has over 20 years experience in the design and implementation of studies involving dietary intake analysis. The research dietitian has worked with NDS-R software for 14 years and conducts the training for the research dietetic technicians.

Body Composition Laboratory

Since the the Body Composition Laboratory and staffed Research Kitchen are both housed on the GCRC, subjects may see the nutrition research staff and have their blood samples, DXA measurements and indirect calorimetry done at one location.

Bone mineral density and total body composition will be measured using a Lunar Prodigy fan beam Dual X-Ray Absorptiometry (DXA) scanner and an RJL Bioelectrical Impedance Analysis Device at the UW GCRC Body Composition Laboratory. The DXA scanner is maintained by a fully trained and accredited DXA technician who also operates a Parvo-Medics 2400 Metabolic Cart and ventilated hood system for determination of resting metabolic rate by indirect calorimetry. The cart is calibrated daily using standard gas mixtures. VO2max testing will be conducted using an exercise testing treadmill with metabolic measurement capabilities and a Quinton Q4500 ECG monitoring machine.
