Study finds diverse gut bacteria of immigrants change once they arrive in the U.S.

The video discusses how geographical location influences the diversity of microbes in the human body, with some areas having more diverse microbial populations. It highlights a study showing that immigrants in the US adopt a Western diet, leading to a 15% reduction in microbiome diversity. This dietary shift changes the dominant gut bacteria from Provotella to Bacteroids, commonly found in Western populations. The video concludes by linking decreased microbiome diversity to increased risks of obesity and diabetes.
