Two members of the workshop planning group—Drs. John W. Suttie and Susan J. Whiting—moderated the DRI Research Synthesis Workshop. After an overview and demonstration of the DRI Research Synthesis Database, panels of experts addressed DRI research recommendations related to each of the six DRI nutrient reports, the two DRI applications reports, and three cross-cutting topics: (1) setting DRIs for children, (2) Tolerable Upper Intake Levels, and (3) relevant new and underutilized research techniques. Periodically, presenters and other attendees took part in lively discussions. During the wrap-up session, moderator John Suttie and four other individuals—from U.S. and Canadian agencies, industry, and academia—provided their perspectives on the workshop.
This report is a summary of the workshop presentations and discussions. Meeting transcripts and slides used during presentations served as the basis for the summary. Topics frequently mentioned by individual participants as continuing knowledge gaps include the following:
Requirements of children, pregnant and lactating women, and the elderly
Individual variation of requirements caused by genetics and epigenetics, lifestyle, environment, and/or geography
The need for biomarkers that are able to predict functional outcomes and chronic diseases
