The
GCRC Bionutrition core offers specialized nutrition services
to all GCRC-approved protocols. It is supported by specialized
instrumentation and a state-of-the-art metabolic kitchen.
The research kitchen is designed to provide clinical research
subjects with meals scheduled and prepared in accordance
with specific protocols. The kitchen offers a meal service
unique to the research setting that includes regular, special,
controlled-nutrient and weighed diets.
In addition to the metabolic kitchen, the Bionutrition core
offers a variety of clinical nutrition services. Clinical
services include nutrition assessment and analysis, body
