High-sugar diet disrupts gut microbiome, leading to obesity (in mice)

A new study in mice has found that sugar may disrupt the community of bacteria that live in the gut, depleting essential immune cells and causing obesity.

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