High-sugar diet alters gut microbiome, causing obesity (in mice)

Sugar can alter the community of bacteria living in the gut, thereby depleting crucial immune cells and causing obesity, a new mouse study suggests.

So far, the results have only been shown in mice. But if follow-up studies show similar trends in humans, it could lead to treatments for metabolic diseases and obesity, said lead author Ivaylo Ivanov, associate professor of microbiology and immunology at the Vagelos College of Physicians and Surgeons of the Columbia University.
