The role of the institutional review board in the oversight of the ethical aspects of human studies research.

Institutional review boards are charged with overseeing that human studies research is conducted in accordance with federal and state regulations and with their own policies and procedures, with the goal of minimizing risks to participants and maximizing the quality of the research data. Nutrition research often involves vulnerable populations, including children and the cognitively impaired, for whom there are specific regulations. Ethical issues are common in nutrition research, and both the investigative team and the institutional review board should seek input regarding ethical issues that arise.
