A probiotic drink in your diet could help control insulin resistance, a major characteristic of diet-induced diseases such as type 2 diabetes, a new study has claimed.
The study, led by Dr Carl Hulston based in the Loughborough University’s School of Sport, Exercise and Health Sciences, suggests that the composition of the gut microbiota is an important factor in understanding metabolic disease in humans.
For the study, seventeen healthy individuals were split into two groups. Both maintained their habitual food intake for the first three weeks of the study.
One of the groups also consumed two bottles of a probiotic fermented milk drink every day.
During the fourth week, both groups were given a high-fat and high-energy diet. The probiotic intake was continued for the same group during this week.
The main finding of the study was that high-fat overfeeding for seven days decreased insulin sensitivity by approximately 27 per cent within these healthy volunteers. But the group that consumed the probiotic drink preserved their glycaemic control and maintained insulin action.
The results provide further indirect evidence that changes in the gut microbiota are involved in the development of human metabolic disease and, furthermore, that supplementation with a probiotic could help prevent insulin resistance caused by excessive consumption of high-fat foods.
“We are already aware that excessive consumption of high-fat foods, even for a short period, can lead to the development of metabolic diseases such as type II diabetes,” said Hulston.
“Therefore the demonstration by this study that a probiotic has the potential to prevent insulin resistance in humans is a significant breakthrough. This warrants further investigation on a larger scale to support our initial findings,” Hulston added.
The study was published in the British Journal of Nutrition
