Evidence-based nutrition

B M Margetts, H H Vorster, C S Venter

Abstract


The evidence-based approach has recently been implemented to translate the vast body of literature available into effective action aimed at addressing the pressing nutritional problems that affect populations. In this paper, the first in a series on the topic, the meaning of evidence-based nutrition (EBN) is clarified and the broad outlines of how to review and interpret both individual papers and reviews of a collection of papers is discussed. The objectives of the EBN approach and the steps to follow in the process are outlined. A useful checklist for the critical appraisal of research papers is given and criteria for reviewing reviews of all relevant available information are discussed. The benefits of the EBN approach are highlighted.
