The benefits of drinking green tea are reduced risk for several cancers, heart disease and hypertension, according to Harvard Medical School. Tea contains a high amount of flavonoids, which are plant-derived compounds that function as antioxidants.
Green tea also contains catechins, which are more powerful than vitamins C and E in reducing oxidative damage to cells, explains Harvard Medical School. Green tea drinkers have reduced risk for skin, breast, bladder, lung, colon and esophageal cancers. The antioxidants in green tea reduce risk for heart disease by lowering LDL cholesterol, increasing HDL cholesterol and improving artery function. Additionally, drinkers of green tea may have a 46 to 65 percent reduced risk for hypertension.
