Glucagon-like peptide-1 (GLP-1) is an incretin that is secreted from enteroendocrine L-cells. Dietary factor-stimulation of endogenous GLP-1 is a promising strategy for increasing the action of GLP-1. Recent studies have shown that berries rich in anthocyanins improve insulin sensitivity and reduce
Blackcurrants are berries that contain high levels of anthocyanins, particularly delphinidin 3-rutinoside (D3R). Several studies have reported that the consumption of blackcurrant extract (BCE) lowers blood glucose levels and ameliorates glucose tolerance, but the mechanism underlying this effect
