Association of the dietary inflammatory index with multi-organ biological age acceleration.

ABSTRACT:

Aim and background

In recent years, the dietary inflammation index (DII) has become an important tool widely used to assess the inflammatory potential of an individual's diet. The aim of this study was to investigate the relationship between the DII and the biological aging of multiple organs (heart, liver, and kidneys) in American adults.

Methods

A cross-sectional study was performed using data from the National Health and Nutrition Examination Survey of American adults between 2003 and 2018. The DII was calculated using 28 nutrients from daily dietary intake. The biological age (BA) of the heart, liver, and kidneys was calculated using the Klemera-Doubal method. ∆ age was determined by assessing the difference between an individual's estimated BA and their actual age.
