Variance in gut microbiome in Himalayan populations linked to dietary lifestyle

The gut bacteria of four Himalayan populations differ based on their dietary lifestyles, according to a new study by researchers at the Stanford University School of Medicine and their collaborators.  All four populations -- the Tharu, the Raute, the Raji and the Chepang -- are longtime residents of the Himalayan foothills, with similar languages, cultural practices and ancestry. Where the four diverge is in their dietary history: The Tharu have practiced agriculture for the past 250 to 300 years; the Raute and the Raji have practiced agriculture for the past 30 to 40 years; and the Chepang are hunter-gatherers. The study found that the composition of the gut microorganisms, or gut microbiome, of each population differed based on whether and how long ago it had departed from a hunter-gatherer lifestyle.  Read more...
