Green tea drinkers show lower cancer risks: Study
NASHVILLE, Tennessee (REUTERS) - Older women who regularly drank green tea may have slightly lower risks of colon, stomach and throat cancers than women who don't, according to a Canadian study that followed thousands of Chinese women over a decade.
The researchers, whose report appeared in the American Journal of Clinical Nutrition, found that of the more than 69,000 women, those who drank green tea at least three times a week were 14 per cent less likely to develop a cancer of the digestive system.
Green tea conctains certain antioxidant chemicals, particularly a compound known as EGCG, that may ward off the body-cell damage that can lead to cancer and other diseases. None of this proves that people should start downing green tea to thwart cancer.
"In this large prospective cohort study, tea consumption was associated with reduced risk of colorectal and stomach/esophageal cancers in Chinese women," wrote study leader Wei Zheng, who heads epidemiology at Vanderbilt University school of Medicine in Nashville, and his colleagues.
