Regularly drinking green tea cuts the risk of all digestive system cancers in women

     Researchers from Vanderbilt University School of Medicine in Nashville, along with researchers from the Shanghai Cancer Institute in China and the National Cancer Institute in Maryland compared green tea consumption and the incidence of cancers of the digestive tract in Chinese women. The study included more than 69,000 middle-aged to older women who participated in the study for eleven years on average.
Over the eleven year study there were 1255 digestive system cancers including cancers of the stomach, esophagus, colon and rectum, liver, pancreas and gallbladder. Regularly drinking green tea was associated with a reduced risk of all digestive system cancers by 16%. However it was also found that the longer the women drank green tea and the more they consumed the greater the decrease in the risk of all digestive system cancers. For instance women who consumed 2 or 3 cups of green tea per day had a 21% reduced risk of all digestive system cancers. The greatest level of protection was for colon, rectal, stomach and esophageal cancers. The study is published in the November 2012 issue of the American Journal of Clinical Nutrition.
