Gut-microbe study races to capture what urban diets erase in urbanising India
Bacteria in the human gut, and not just genes, may help explain why urbanising Indians face rising rates of diabetes, obesity and hypertension. This is from a three-year study that has produced what its authors describe as the first reference database of the gut microbiome across South Asia.The study, published in the peer-reviewed Gut Microbes, sampled 575 adults from 10 communities across India and Sri Lanka and profiled their gut bacteria through gene. Niraj Rai of the Birbal Sahni Institute of Palaeosciences, Lucknow, who led the work with Maanasa Raghavan of the University of Chicago, said India offered a rare natural experiment.
