The association between dietary quality and biological aging: two-mediation analysis.

ABSTRACT:

Aims

Previous research has emphasized the firm link between diet and human health. However, the connection between comprehensive dietary patterns and biological aging has not been fully investigated. Our aim was to explore the potential association between dietary quality and delaying aging.

Methods

A total of 20,763 participants from the National Health and Nutrition Examination Survey were included in this cross-sectional study. The Mediterranean diet score (MDS), dietary approaches to stop hypertension index (DASHI), and healthy eating index 2020 (HEI2020) were utilized to assess dietary quality. Biological age was determined using the Klemera-Doubal method (KDM) biological age and phenotypic age (Levine's), with the difference between biological age and chronological age
