Takeaways
Our gut microbiota, the community of microbes in our gastrointestinal tract, is associated with many aspects of health, including weight. People living in less industrialized places often have a greater diversity of microbes in their gut communities than those living in more industrialized nations.
In this study, when women from Thailand immigrated to the US or were born of such immigrants in the US, their gut microbe communities soon came to resemble those of Americans of European descent, with lower diversity of species. They also tended to gain weight.
However, the diets of these immigrants and children of immigrants didn't resemble the typical American diet as closely as one might expect, suggesting that there may be other factors affecting the gut community of these women.
