Long-term diet quality is associated with gut microbiome diversity and composition among urban Chinese adults.

ABSTRACT:

Background

Few population-based studies have evaluated the influence of long-term diet on the gut microbiome, and data among Asian populations are lacking.

Objective

We examined the association of long-term diet quality, comprising 8 food groups (fruit, vegetables, dairy, fish/seafood, nuts/legumes, refined grains, red meat, and processed meat), with gut microbiome among Chinese adults.

Methods

Included were 1920 men and women, enrolled in 2 prospective cohorts (baseline 1996-2006), who remained free of cardiovascular diseases, diabetes, and cancer at stool collection (2015-2018) and had no diarrhea or antibiotic use in the last 7 d before stool collection. Microbiome was profiled by 16S rRNA sequencing. Long-term diet was assessed by repeated surveys at baseline and
