Lower socioeconomic status (SES) is related to increased incidence and mortality due to chronic diseases in adults. Association between SES variables and gut microbiome variation has been observed in adults at the population level, suggesting that biological mechanisms may underlie the SES associations; however, there is a need for larger studies that consider individual- and neighborhood-level measures of SES in racially diverse populations. In 825 participants from a multi-ethnic cohort, we investigated how SES shapes the gut microbiome.

- A study investigated how habitual consumption of whole grains, refined grains, fiber, and gluten affects the gut microbiome in 779 participants, using stool samples and dietary assessments.* -
- Results indicated that higher whole grain intake is linked to a more diverse gut microbiome, with specific beneficial bacteria being more abundant, while refined grains and gluten consumption is associated with lower microbial diversity.* -
- These findings suggest that eating whole grains and fiber could reduce colorectal cancer risk, but more research is needed on the impact of refined grains and gluten on gut health.*
Tobacco Smoking and the Fecal Microbiome in a Large, Multi-ethnic Cohort.
Cancer Epidemiol Biomarkers Prev
July 2021
Background: Increasing evidence suggests that tobacco smoking, a well-known driver of carcinogenesis, influences the gut microbiome; however, these relationships remain understudied in diverse populations. Thus, we performed an analysis of smoking and the gut microbiome in a subset of 803 adults from the multi-ethnic NYU FAMiLI study.
Methods: We assessed fecal microbiota using 16S rRNA gene sequencing, and clustered samples into Amplicon Sequence Variants using QIIME2.
Little is known regarding the impact of immigrant acculturation on the gut microbiome. We characterized differences in the gut microbiome between racially/ethnically diverse US immigrant and US-born groups, and determined the impact of dietary acculturation on the microbiome. Stool samples were collected from 863 US residents, including US-born (315 White, 93 Black, 40 Hispanic) and foreign-born (105 Hispanic, 264 Korean) groups.
