Oligomeric polyphenol-enriched specified kiwifruit extract (SKE) is reported to inhibit pancreatic lipase activity in vitro. Therefore, in this work, we investigated the effects of SKE on body weight, visceral fat, and lipid metabolism in mice fed a high-fat diet for 6 weeks. Body weight gain was significantly and dosedependently suppressed in the groups fed a high-fat diet containing SKE (HF + SKE groups) compared to the high-fat diet control group (HF group). Moreover, Dose-dependent increases in triglyceride (TG) content in feces were observed in the HF + SKE groups. Since we confirmed that SKE inhibits lipase in vitro, these findings indicate that SKE suppresses the hydrolysis of TG by inhibiting lipase activity in the intestinal tract, thereby restricting the absorption of lipids, increasing the excretion of TG in feces, and suppressing the increase in body weight and visceral fat caused by the high-fat diet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
