Trial Design

The Human Nutrition Unit carries out intervention trials investigating the relationships between diet and markers of health and disease.

Trials are randomised, placebo-controlled, single or double blind interventions and may be of either a cross-over or parallel design.

All trials are required to conform to human ethics procedures and good clinical practice (GCP), and human ethics committee approval is mandatory. Therapeutic trials are also required to obtain NZ Standing Committee on Therapeutic Trials (SCOTT) and MedSafe approval.

  • Day stay (single day) studies carried out within the Human Nutrition Unit research clinic
  • Longer term (1-4 weeks) residential studies carried out within the Human Nutrition Unit residential facility
  • Long term (3-6 months) community studies which require visits to the Human Nutrition Unit research clinic for blood tests and other measurements
