Résumé : | Background Results from observational studies suggest high diet quality favorably influences the human gut microbiome. Fruit and vegetable consumption is often a key contributor to high diet quality. Objective To evaluate measures of gut bacterial diversity and abundance in relation to serum biomarkers of fruit and vegetable intake. Design Secondary analysis of cross-sectional data. Participants and setting Men and women from Los Angeles, CA, and Hawai?i who participated in the Multiethnic Cohort?Adiposity Phenotype Study from 2013 to 2016 (N = 1,709). Main outcome measures Gut microbiome diversity and composition in relation to dietary biomarkers. Statistical analysis Carotenoid (beta carotene, alpha carotene, cryptoxanthins, lutein, lycopene, and zeaxanthin), tocopherol (?, ? + ?, and ?), and retinol concentrations were assessed in serum. The ? and ? diversity and composition of the gut microbiome were classified based on 16S rRNA gene sequencing of bacterial DNA from self-collected fecal samples. Global differences in microbial community profiles in relation dietary biomarkers were evaluated using multivariable permutational analysis of variance. Associations of ? diversity (Shannon index), ? diversity (weighted and unweighted UniFrac) with center log-ratio?transformed phyla and genera abundances were evaluated using linear regression, adjusted for covariates. Results Increasing total carotenoid, beta carotene, alpha carotene, cryptoxanthin, and lycopene concentrations were associated with higher gut bacterial diversity (Shannon Index) (P |
