Green tea reduces the risk of developing cancer
Evidence for the benefits of green tea continues to mount. A study of nearly 70,000 Chinese women showed a significant reduction in the risk of developing colorectal cancer in women who drank green tea regularly, with the greatest reduction among those who drank more tea overall and who drank it regularly. (Prospective cohort study of green tea consumption and colorectal cancer risk in women. Cancer Epidemiol Biomarkers Prev 2007; 16: 1219-23).
In another study of over 50,000 Japanese adults (40-79 years of age), women who drank from one to five or more cups of green tea a day showed a 40-70 percent reduced risk of developing oral cancer (depending on the amount of green tea consumed). No such benefit was demonstrated for men. (A prospective study of green tea consumption and oral cancer incidence in Japan. Ann Epidemiol 2007; doi: 10.1016/j.anneepidem.2007.04.003).
