A number of scientific studies have demonstrated the hypoglycemic effect of BBR on T2DM; for example, BBR could improve insulin sensitivity and promote insulin secretion; BBR regulates glucose and lipid metabolism in liver via modulating the PPARs protein expression; BBR reduces intestinal absorption of glucose; BBR possesses antioxidant activities aimed at diabetic complications [19–28]. This evidence concerns the gene INS and type 2 diabetes mellitus.
