Anthocyanin intake is associated with improved memory in older adults with mild cognitive impairment

Research on the role of dietary anthocyanins in preventing cognitive decline in older adults shows promise. This study investigated the association between usual anthocyanin intake and indices of memory and cognition in 40 older adults diagnosed with mild cognitive impairment that were recruited to a randomized clinical trial. It was hypothesized that daily anthocyanin intake would be similar to healthy older adults and that higher anthocyanin intake would be associated with better cognitive performance. Cognitive performance was assessed using a battery of tests including the Rey Auditory Verbal Learning Test (RAVLT). Dietary intake was assessed through 3-day food records and anthocyanin intake was quantified using the PhenolExplorer food composition database. Multivariate linear regression compared differences in cognitive performance between higher (>10 mg/d) and lower consumers (
