Background Maintaining brain health is an advanced goal of healthy ageing. Eating a diet with appropriate nutrients has been identified as a promising approach to reducing the risk of dementia, but community-dwelling residents have inadequate or no health guidance from medical workers since there is no detailed and comprehensive clinical dietary nutrients management program for brain health promotion for community-dwelling people . Objective To search, evaluate and summarize the evidence on dietary nutrients management for brain health promotion in community-dwelling people, providing an evidence-based basis for clinical implementation of such management for this group of population. Methods In March 2022, we searched UpToDate, BMJ Best Practice, JBI Model of Evidence-based Healthcare, National Institute on Aging, Registered Nurses' Association of Ontario, the Cochrane Library, PubMed, CNKI, Medlive and other databases to collect literature (involving clinical decisions, recommended practices, guidelines, evidence summaries, expert consensuses and systematic reviews) regarding dietary nutrients management for brain health promotion in community-dwelling people. The retrieval period was from January 1, 2017 to March 29, 2022. Two researchers systematically trained in evidence-based medicine independently screened literature, extracted data, and evaluated the quality of the included literature. Then evidence was extracted from the included literature, and its quality was graded, then the best evidence was summarized. Results A total of 28 studies with an overall high methodological quality were included, including three clinical guidelines, five expert consensuses, one clinical decision and 19 systematic reviews. Finally, 23 pieces of best evidence were summarized, involving seven aspects of intervention timing, dietary nutrients assessment and screening, dietary patterns and components, specific nutrients, coffee intake, body weight management, health education and guidance. Conclusion Eating a diet with appropriate nutrients can promote brain health of residents. Community medical workers should develop an individualized dietary nutrients management program for brain health for them in accordance with the practical clinical situation, residents' current dietary nutrients status and preferences, and insights from the best evidence.
