Why food with high sugar content is bad for the gut
According to a study conducted by researchers at Columbia University Vagelos College of Physicians and Surgeons, dietary sugar alters the gut microbiome, which leads to obesity, metabolic syndrome, and diabetes.
The study was conducted on mice, and the findings were published in the 15 September 2022 issue of the Cell journal.
After the animals that participated in the study were kept under a high-fat, high-sugar diet for four weeks, the amount of segmented filamentous bacteria in their microbiome fell sharply, while other bacteria showed a rapid increase.
The drop in filamentous bacteria reduced the number of Th17 cells in the gut, which were found to be necessary for preventing metabolic disease, diabetes, and weight gain, as seen in the participants.
“These immune cells produce molecules that slow down the absorption of ‘bad’ lipids from the intestines, and they decrease intestinal inflammation,” explained Ivaylo Ivanov, PhD, associate professor of microbiology & immunology at Columbia University Vagelos College of Physicians and Surgeons and one of the authors of the paper, in a university journal.
“In other words, they keep the gut healthy and protect the body from absorbing pathogenic lipids.”
