The American diet can compromise the microbiome

New research shows that immigrants from Southeast Asia lose their gut microbiome diversity almost immediately after relocating to the U.S. The article, published in Cell, also revealed that as the microbiome diversity of these immigrants dropped, obesity and other metabolic disease rates became much more common. The American diet—higher in fats, protein and sugar than the Asian diet—is also lacking in fiber (prebiotics), which researchers say caused the dramatic decrease in diversity of bacteria in the gut microbiome.
