Overview

Cross-sectional and longitudinal associations explore brain volume changes in older adults, suggesting dietary diversity impacts cognitive health.

Key Points

  • This research aims to clarify the relationship between dietary variety score and brain volume changes in older adults.
  • Examined cross-sectional and longitudinal data from the NEIGE cohort of community-dwelling older Japanese adults.
  • Assessed dietary variety score using standardized dietary assessments.
  • Measured brain volume through neuroimaging techniques.
  • Found significant associations between higher dietary variety score and increased hippocampal volume.
  • Noted a reduction in grey matter volume over time for those with lower dietary diversity.
  • Indicated a protective effect of dietary diversity against cognitive decline.
