A high-sugar diet disrupts the gut microbiome, leading to obesity (in mice)

Sugar may disrupt the community of bacteria in the gut, 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 eventually lead to treatments for metabolic disease and obesity, said senior author Ivaylo Ivanov, an associate professor of microbiology and immunology at Columbia University Vagelos College of Physicians and Surgeons.
