Abstract

Growing evidence suggests that polyphenols could mitigate type 2 diabetes mellitus (T2DM). The glucose-regulatory effects of protein-bound polyphenols, however, have been rarely studied. In this study, macrogenomic and metabolomic analyses were applied to investigate the modulation of myofibrillar protein-chlorogenic acid (MP-CGA) complexes on T2DM rats from the gut microbiota perspective. Results showed that MP-CGA improved hyperglycemia and hyperlipidemia, decreased intestinal inflammation, and reduced intestinal barrier injury. MP-CGA reconstructed gut microbiota in T2DM rats, elevating the abundance of probiotics Bacteroides, Akkermansia, and Parabacteroides while suppressing opportunistic pathogens Enterococcus and Staphylococcus. MP-CGA significantly elevated the concentrations of intestinal metabolites like butyric acid that positively regulate T2DM and reduced the secondary bile acids contents. Therefore, MP-CGA modulated the gut microbiota and related metabolites to maintain stable blood glucose in T2DM rats, providing new insights into the application of protein-polyphenol complexes in foods.
