Dietary habits and the gut microbiota in military Veterans: results from the United States-Veteran Microbiome Project (US-VMP).

ABSTRACT: Dietary patterns influence gut microbiota composition. To date, there has not been an assessment of diet and gut microbiota in Veterans, who have a history of unique environmental exposures, including military deployment, that may influence associations between diet and gut microbiota. Our aim was to characterise Veteran habitual dietary intake and quality, and to evaluate correlations between diet and gut microbiota. We administered Food Frequency Questionnaires (FFQs) and collected stool samples from 330 Veterans. FFQ data were used to generate Healthy Eating Indices (HEI) of dietary quality. Exploratory factor analysis was used to identify two dietary patterns we defined as "Western" and "Prudent." Stool samples underwent 16S rRNA gene sequencing, and the resulting data were used to eva
