Dietary patterns in middle age: effects on concurrent neurocognition and risk of age-related cognitive decline
Gauci S, Young LM, Arnoldy L, Lassemillante AC, Scholey A, Pipingas A.. Nutrition reviews, 2022-04-01
Topic: Risk, prevention and care in population studies
Context Diet plays a critical role in cognitive integrity and decline in older adults. However, little is known about the relationship between diet and cognitive integrity in middle age. Objective To investigate the relationship between dietary patterns in healthy middle-aged adults and neurocognition both in middle age and later in life. Data sources Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, the following electronic databases were searched: Web of Science, Scopus, PubMed, and PsychInfo. Data extraction Data from eligible articles was extracted by 2 reviewers. Data analysis Articles included in the systematic review were synthesized (based on the synthesis without meta-analysis reporting guidelines) and assessed for quality (using the Joanna Briggs Institute checklist for randomized controlled trials, cohort studies, and cross-sectional studies) by 2 reviewers. Results Of 1558 studies identified, 34 met the eligibility criteria for inclusion. These comprised 9 cross-sectional studies, 23 longitudinal or prospective cohort studies, and 2 randomized controlled trials. Findings were mixed, with some studies reporting a significant positive relationship between adherence to various "healthy" dietary patterns and neurocognition, but others reporting no such relationship. Conclusion This systematic review demonstrated that adherence to the Mediterranean diet and other healthy dietary patterns in middle age can protect neurocognition later in life. Systematic review registration PROSPERO registration no. CRD42020153179.

How this study scored 71/100
Published in a peer-reviewed journal, and it is a systematic review of all the studies on the question. Scored zero for sample size, effect reported and studied in people because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 41 of the 58 points we could judge it on, which is 71 out of 100.
