Gut Microbiome: Westernization and the Disappearance of Intestinal Diversity

Curr Biol. 2015 Jul 20;25(14):R611-3. doi: 10.1016/j.cub.2015.05.040.


The environment shapes our intestinal microbiome. By contrasting the gut microbiomes of African hunter-gatherer and European subjects, a new study reveals that urbanization is associated with a loss of microbial organisms and genes. What will be the consequences of the lost biodiversity in the sanitized, western-diet world?
