Diet modifies gut bacteria genetics making it more permeable to infections

26 jan 2022

New research from Instituto Gulbenkian de Ciência reveals that diet can change the evolutionary path of bacteria in the gut, within host-relevant timescales. The study, published in Cell Host & Microbe, demonstrates how quickly Bacteroides thetaiotaomicron (B. theta), a prevalent bacterium in the human gut, acquires adaptive mutations in response to dietary changes. These findings show that acquisition of genetic changes can explain the observed microbiota-mediated negative effects that unbalanced diets have on host health.
