In a 2022 randomized clinical trial, participants who followed a calorie-restricted MIND diet for three months scored higher in working memory, verbal recognition memory, and attention than participants in a calorie-restricted control group.

Notes on verification

Confirmed directly by the peer-reviewed primary source (Scientific Reports, 2022) with matching effect sizes and p-values; corroborated by PubMed, PMC, and ClinicalTrials.gov listings. Small sample size (37 completers, obese women only) limits generalizability, and a larger 2023 NEJM trial found no significant long-term cognitive effect, so results should be framed as study-specific rather than universal.
