A large-scale study suggests that green tea may play a role in lowering risks of colon, stomach and throat cancers for older women. Scientists from Vanderbilt University School of Medicine in Nashville followed 69,000 women for a period of ten years and found that those who drank green tea at least three times a week were 14 percent less likely to develop a cancer of the digestive system. Furthermore, the study found that women who drank green tea for at least 20 years were 27% less likely than non-drinkers to develop any digestive system cancer. Although researchers admit only clinical studies can establish a direct link, they did account for other factors like diet, income, exercise habits and medical history in their study and still found a benefit of drinking green tea.
