Green Tea Japanese scientists suggest that drinking daily five or more cups of green tea could halve the risk of developing advanced prostate cancer.

According to the article published in the American Journal of Epidemiology, there was a 50 percent lower risk of having advanced prostate cancer in men who drank five or more cups of green tea daily compared with those who had less than a cup.

Findings show while drinking green tea lowers the risk of advanced prostate cancer; it is not associated with localized prostate cancer.

Researchers claim that a substance called catechin in green tea is responsible for reducing cancer risk by curbing testosterone levels which cause prostate cancer.

The study suggests that the lower incidence of prostate cancer in Asians may be linked to the higher consumption of green tea.

Previous studies had reported various health benefits for the green tea catechin including reduced heart attack and cancer risks.
