Background Maintaining brain health is an advanced goal of healthy ageing. Nutrition has been identified as a promising approach to reduce the risk of dementia, but there is currently a lack of targeted nutritional management to promote brain health in clinical practice, resulting in lack or inadequate health guidance.?Objective To search and evaluate studies about dietary nutrition management to promote brain health, and to provide evidence-based basis for clinical development of dietary nutrition management of brain health.?Methods We searched UpToDate, BMJ Best Practice, JBI Library, NIA, RNAO, Cochrane Library, PubMed, CNKI, Medlive and other databases to collect clinical decisions, best practices, guidelines, evidence summaries, expert consensus and systematic reviews regarding dietary nutrition management to promote brain health from January 1,? 2017 to March 29, 2022. The quality and evidence level of the literature were assessed by two researchers systematically trained on evidence-based medicine. Results A total of 28 articles were included, including 3 clinical guidelines, 5 expert consensus, 1 clinical decision and 19 systematic reviews. Their methodological qualities were rated high overall. Finally 23 pieces of best evidence involving 7 aspects were intervention timing, dietary nutrition assessment and screening, dietary patterns and components, specific nutrients, coffee intake, weight management, health education and guidance. Conclusion Dietary nutrition can promote brain health. Community medical staff should choose and apply the best evidence based on clinical situation, residents' dietary nutrition status and preferences, so as to develop individualized dietary nutrition program for brain health.
