Green Tea May Reduce Prostate Cancer Risk
Drink green tea may reduce the risk of advanced prostate cancer, according to a study by Japanese researchers from the National Cancer Center.
This study says that men who drink five or more cups of green tea a day may reduce the risk of developing prostate cancer compared with those who drank less than one cup a day.
"This does not mean that people who drink green tea are guaranteed to have a lower risk of advanced prostate cancer, "said Norie Kurahashi, a Japanese scientist who participated in the study. He also said that while they are still presenting their findings, the study points to the hope that drinking green tea reduces the final half the chances of developing prostate cancer.
Prostate cancer is much less common among Asian men than among Westerners, and this may be partly due to the effects of high consumption of green tea in Asia says the study.
However, further studies are needed to confirm the preventive effects green tea on prostate cancer, including well-designed clinical trials.
In the study, published in American Journal of Epidemiology , collected data on 50,000 men between the ages of 40 and 69 years in a period of up to 14 years from 1990.
But in contrast to this study, Cancer Research UK the UK has published on its website that a study of nearly 20,000 Japanese men published in the British Journal of Cancer in 2006 found no link between the Green tea and prostate cancer.
