Effects of dietary diversity on frailty in Chinese older adults: a 3-year cohort study.

ABSTRACT:

Background

Frailty has emerged as a global health burden with increased population aging. A diverse diet is essential for an adequate and balanced supply of nutrients. However, limited evidence supports the relationship between dietary diversity and frailty. We therefore assessed the associations of dietary diversity with the risk of frailty.
