Associations Between Healthy and Plant-Based Dietary Patterns and Cognitive Reserve: A Cross-Sectional Analysis of the 1946 British Birth Cohort.

ABSTRACT:

Background

Cognitive reserve (CR) is the ability to compensate for brain changes, injury, and disease, and it is measured by acquired knowledge and experiences. Genes and environmental factors influence CR, but the role of diet is unclear.

Objectives

This study examined associations between CR and alignment with different dietary patterns and investigated diet's unique contribution to variability in CR.

Methods

We applied cross-sectional methods to data from the National Survey of Health and Development's 1946 British Birth Cohort. National Adult Reading Test (NART) scores at age 53 identified CR levels. Scores for the Healthy Eating Index (HEI)-2020 and Plant-Based Diet Indexes (PDIs overall, healthful [hPDI], and unhealthful [uPDI]) were calculated from diet recalls
