Abstract

This study investigates the impact of cocoa (Theobroma Cacao L.) flavonoid-rich aqueous supplementation on alpha-amylase and alpha-glucosidase enzymes, influencing glucose homeostasis in Wistar rats. Over 12 weeks, Wistar rats underwent a high-fat diet induction for obesity. Group assignments included a negative control on a normal diet, a positive control on a normal diet with 600 mg/kg cocoa-containing flavonoid-rich water extract, a fat-treated group on a high-fat diet with the same cocoa extract, and an untreated fat group exclusively on a high-fat diet. The cocoa extract was orally administered for 14 days, evaluating various metabolic parameters. Results showed that the rats displayed improved glucose tolerance, reduced fasting serum glucose, and enhanced insulin sensitivity with increased alpha-amylase and alpha-glucosidase levels compared to the untreated high-fat group and controls. This study suggests that cocoa-derived polyphenols hold potential in mitigating high-fat diet-induced adverse effects on glucose metabolism by regulating the secretion of alpha-amylase and alpha-glucosidase in rats.
