Scientists discover that fiber-fermenting bacteria has the potential to improve health of type 2 diabetic patients, according to a study published on March 8, 2018.
Researchers at the School of Environmental and Biological Sciences at Rutgers University-New Brunswick have found that diet high in diverse fibers results in better blood glucose control, higher weight loss, and better lipid levels in people suffering from type 2 diabetes. The study was carried on for six years, after which the scientists were able to draw to the conclusion that intake of the right dietary fibers in high proportions has the potential to rebalance the gut microbiota, gastrointestinal tract. This in turn, helps in better digestion of food and improve overall human health.
“Our study lays the foundation and opens the possibility that fibers targeting this group of gut bacteria could eventually become a major part of your diet and your treatment,” said Liping Zhao, lead author of the study. Clinical studies also show that increasing consumption of dietary fibers could improve type 2 diabetes.
A study in China by Zhao included patients suffering from type 2 diabetes, further randomizing them into two groups. The control group received standard patient education and dietary recommendations. The treatment group was given a large amount of many types of dietary fibers while ingesting a similar diet for energy and major nutrients. Both the groups were also given drug acarbose to help control blood glucose.
The high-fiber diet provided to the individuals included whole grains, traditional Chinese medicinal foods rich in dietary fibers, and prebiotics. Patients who were on the high-fiber diet showed greater reduction in a three-month average of blood glucose levels. Their fasting blood glucose levels also dropped faster and they lost more weight.
