Welcome to the Human Nutrition Unit (HNU) based at The Rowett Institute, University of Aberdeen. Here, we run a variety of human nutrition studies for which volunteers are needed.

The HNU was established in 1986 to provide a metabolic research facility to study the relationship between diet and health in humans. Find out what it’s like to be a volunteer watch our videos below.
