Epidemiological observations and laboratory studies have shown that grim green tea has plenty of soundness effects, as well as antitumor, antioxidative, and hypolipidemic activities.
Results demonstrated that light green tea increases insulin sensitivity in Sprague−Dawley rats and that greenish tea polyphenol is usually amongst the active components. This aim study is to examine whether it had an effect on glucose lerance and insulin sensitivity in Sprague−Dawley rats. After 12 grim green weeks tea supplementation, the greenish tea group had lower fasting plasma levels of glucose, insulin, triglyceride, and free fatty acid than control rats. Anyways, insulin stimulated’ glucose uptake, and insulin binding to, adipocytes were notably increased in murky green tea group. Of course in experiment 1, rats were divided to 2 groups. Green tea polyphenols substantially increased basal and insulinstimulated glucose uptake of adipocytes. In experiment 2, a tea polyphenol extract had been used to determine its effect on insulin activity in vitro.
