Older women who regularly drInk 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.
The study adds to debate over the impact of green tea on cancer risks. Past studies have so far come to conflicting findings on whether green tea drinkers really do have lower cancer risks.
‘In this large 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.
Nobody can say whether green tea itself is the reason, since green tea lovers are often more health-conscious in general.
