4. Reduce cholesterol absorption: Studies have found that black rice extract reduces cholesterol absorption by inhibiting pancreatic lipase, reducing micellar cholesterol solubility and inhibiting cholesterol absorption by Caco-2 cells. The inhibitory activity is positively correlated with the content of anthocyanins in the extract: cyanidin-3-glucoside (C3G) and peony-3-glucoside (Pn-3-G).
5. Anti-diabetes: Studies have found that cyanidin-3-glucoside (C3G) in black rice has a hypoglycemic effect on diabetic rats. 8 weeks of C3G supplementation can reduce blood glucose and serum insulin in diabetic nephropathy (DN) rats, improve renal function, and reduce glomerular sclerosis and interstitial fibrosis. In addition, the oxidative defense system of the kidneys of DN rats was improved. Proinflammatory mediators in serum and kidneys of the C3G treatment group were significantly reduced. The expression levels of transforming growth factor β1 (TGF-β1), phosphorylated Smad2, and phosphorylated Smad3 proteins in the kidneys of the C3G treatment group were significantly reduced, while the expression level of Smad7 was upregulated by C3G. This suggests that black rice C3G can be used as a renal protective nutrient for DN patients.
