reen tea polyphenol is widely known to have an antioxidant effect in human and rats. Polyphenol, which extracted from green tea, has bitter taste and hard to gain. Therfore, in the present study, green tea was used as the supplement itself. Thirty two rats were divided into control (CON) and high fat fed (HF) group, and they were sub-grouped as water as a placebo (W) and green tea (GT) ingestion group, respectively. They have exercised on the treadmill and fed 43% of fat diet or normal diet for 5 weeks. Green tea, packed with the leaf, was solved in the hot water (85℃) for 5 min and 100㎖ was supplied every 8 A.M. Blood TC, HDL-C, and TG were analyzed using enzymatic methods and LDL-C was calculated by reported previously. SOD and MDA were analyzed to prove antioxidant effect of green tea. Body weight and food consumption were not significantly different between groups. TC and HDL-C were significantly between CON and HF group (p<0.05). TG was significantly lower in GT of HF group (p<0.05). MDA content was significantly lowed in GT in HF group (p<0.05). These results suggested that green tea ingestion lowers the lipid peroxidation and risk of obese when HF diet fed rats. |
