A recent scientific study has shown that compounds found in blueberries, especially anthocyanins, affect blood sugar levels and the composition of gut microbes in patients with type 2 diabetes.
The study included 15 adults with type 2 diabetes. The participants were divided into two groups. The first group received 400 milligrams of blueberry anthocyanin extract daily, while the second group did not take any supplements for six months. Although no statistically significant improvements were achieved in glycated hemoglobin (HbA1c) levels in the first group, positive indications of reduced blood glucose levels were observed in them.
The researchers also found that taking anthocyanin supplements derived from blueberries led to a significant change in the composition of gut microbes, reducing the abundance of Vermicelli bacteria, which can stimulate inflammation, and increasing the abundance of Bacteroides bacteria, which are associated with improved metabolism.
The researchers also noted that taking this dietary supplement led to increased levels of short-chain fatty acids in the stool, indicating improved metabolic processes in the body.
These results suggest that blueberry extract may be a useful adjunct in the treatment of type 2 diabetes.
