Before undertaking research involving subjects in developing communities, the researcher must ensure that:

1. 1. People in developing communities do not participate regularly in research that can be done reasonably in developed communities;
   2. The research meets the needs of food and nutrition security and the priorities of the community in which it takes place;
   3. Make everything possible to safeguard the ethical imperative that the consent of each subject is informed; and
   4. The research project has been reviewed and approved by a Committee of ethical evaluation that has among its members or consultants persons who know the Customs and traditions of the community.
