Mediterranean-style diet linked to better cognitive functioning in elderly, Finds study
Researchers have recently noted that adherence to a Mediterranean-style diet is associated with better cognitive functioning, but not better brain structural integrity, in older adults, as published in the Experimental Gerontology Journal.
Few studies have explored dietary patterns with cognitive and neuroimaging outcomes. Therefore, Janie Corley colleagues from the Lothian Birth Cohorts Group, Department of Psychology, University of Edinburgh, UK conducted this present study to examine the cross-sectional associations between dietary patterns and cognitive and neuroimaging indices of brain health concurrently in the same sample of healthy older adults.
Dietary patterns were derived from a 130-item food frequency questionnaire for 511 individuals in the Lothian Birth Cohort 1936 (mean age 79.3 ± 0.6 years). Composite scores for global cognitive function, visuospatial ability, processing speed, memory, and verbal ability were assessed. Brain volumes and white matter microstructure were assessed in participants (n = 358) who also underwent structural magnetic resonance imaging.
