Clinical Research Core

The Clinical Research Core (CRC) provides human nutrition research investigators with multi-disciplinary services and equipment in one location. The core is complete with examination rooms and equipment, phlebotomy and processing areas, pharmacy, and furnished consultation rooms. For nutrition intervention studies, the CRC offers a metabolic kitchen specifically designed to support nutrition research.

State-of-the-Art Resources and Support

• Human metabolism and body composition assessments
• Clinical laboratory and support services
• Preparation and delivery of precisely designed meals for study participants

The CRC – a part of UNC NORC – is available for academic, public and private research. The core encourages collaborative as well as independent research and is committed to conducting innovative, basic, and translational science to support the understanding of precision nutrition. These advances in science promote the prevention and reduction of metabolic diseases such as obesity, type 2 diabetes and cardiovascular diseases.

Human Whole-Room Calorimeter

Our advanced research suite uses indirect calorimetry to evaluate a research participant’s 24-hour energy balance (intake and expenditure). The suite is equipped with a bed, treadmill, bathroom, airlock chamber for entry of food, ports for blood draws and entertainment options. Data can be collected without interruption during meals, sleep and light activity. Monitoring, consenting, scrubs, supplies, technicians and analysis upon completion are included. The Whole-Room Calorimeter is essential for studies on energy balance and fuel use.

Metabolic Research Kitchen

Investigators work with a Registered Dietitian to design, prepare and serve precisely composed meals with a safe, accurate and consistent approach. The kitchen is equipped with commercial appliances and professional software. A spacious dining area, adjacent to the kitchen, is available to accommodate up to 50 research participants for diet intervention studies.
