Scientists discovered which gut bacteria may increase the risk of developing diabetes 22:31

Prevotella copri, a bacteria that produces branched-chain amino acids (BCAAs), is more common in the intestines of people with diabetes. People with chronically high levels of BCAAs in their blood face a greater risk of obesity and diabetes than others. These results were led by T.H. Chan of the Massachusetts Institute of Technology and Harvard as part of the scientific team. results of work published In the journal Nature Medicine (NatMed).

Scientists analyzed the composition of the gut microbiomes of people with type 2 diabetes (T2DM), prediabetes, and normal blood sugar levels. It was noted that volunteers were recruited from the USA, Israel, Sweden, Finland, Denmark, Germany, France and China. The status of the colon microbiota was evaluated by examining stool samples.

Researchers have found that certain types of gut bacteria have different functions, such as the production of certain amino acids, that may be associated with the risk of developing T2DM. Scientists found that the bacteria Prevotella copri, which can specifically produce large amounts of branched-chain amino acids (BCAAs), were more prevalent in the gut microbiome of patients with diabetes. Previous studies have shown that people with chronically high levels of BCAAs in their blood have a higher risk of developing obesity and diabetes.

It also turns out that bacteriophages (viruses that infect bacteria) can cause changes in certain types of gut bacteria and indirectly trigger diabetes. Scientists explained that viruses can infect bacteria and change their functions in ways that can increase or decrease the risk of developing this disease.

The researchers noted that more research is needed to determine exactly how bacteriophages and bacteria affect health. They suggested that the gut microbiome could be altered through dietary changes, fecal transplants, or probiotics. Such interventions may affect the risk of developing diabetes.
