Hunter-gatherers' seasonal gut-microbe diversity loss echoes our permanent one -- ScienceDaily

Hunter-gatherers' seasonal gut-microbe diversity loss echoes our permanent one -- ScienceDaily:



More evidence that our intestinal microbes are profoundly influenced by the foods we eat -- or don't: The gut ecosystems of members of a small group of hunter-gatherers inhabiting Tanzania's Rift Valley show a strong cyclicality consistent with the population's seasonally changing diet.
A study led by researchers at the Stanford University School of Medicine is the first to look at seasonal variations in the gut-microbial composition, or microbiota, of the Hadza, one of the world's few remaining traditional hunter-gatherer populations. The findings confirm that the Hadza microbiota is more diverse than, and substantially different from, that of industrialized countries' urban-dwelling denizens.
