Description: An expert group was convened by IAFNS in March 2022 to discuss the current issues surrounding cognitive task selection in nutrition research. One of the outcomes of this meeting was that it was decided that many reviews had already been undertaken in this area, so it was more appropriate to conduct a systematic review of the existing reviews, so as to identify the best ways to move the area forward. The main questions the review will try to address are: What are the current issues surrounding cognitive task selection in nutrition research? Based on this, what are some possible solutions towards informing dietary guidance for cognitive health, to address a gap identified in the 2020 US DGAC report, specifically the “considerable variation in testing methods used, [and] inconsistent validity and reliability of cognitive testing methods” (p.31)?
