From: The adoption of a westernized gut microbiome in Indian Immigrants and Indo-Canadians is associated with dietary acculturation

Graphical representation highlighting the main findings from our study. As Indo-Immigrants and Indo-Canadians subsequently increased ultra-processed food intake, their fiber consumption dramatically reduced. This change in dietary pattern was observed alongside a transition away from high Prevotella spp., which were found abundant in the Indian gut. Instead, Indo-Canadians adopted BloSSUM (Bloom or Selected in Societies of Urbanization/Modernization) taxa, which are commonly found in the westernized microbiome. High Prevotella copri in the Indian gut contributed to enriched carbohydrate-active enzymes (CAZymes) that are specialized to degrade complex carbohydrates common in their diet, which decline in Indian migrant cohorts. Additionally, the Indian microbiome displayed characteristics of a more robust gut, with predictive functions of higher stress tolerance and increased microbial cell turnover. Figure was drawn by hand in Procreate.
