Green tea and prostate cancer

Here's an article, from Forbes (of all place), about another study that found that green tea may curb prostate cancer in men.


In the study, conducted at the University of Parma in Italy, researchers held a trial with two groups of men, both with a pre-cancerous condition that normally progresses to cancer it 30% of men. One group was given a placebo to take, whereas the second group was given 600 milligrams of green tea catechins a day, "equivalent to 12-15 cups of green tea infusion, that is about two times the average intake in Asian countries."


Nine out of the 30 men given the placebo group developed full-blown prostate cancer, a rate of 30%. But only 1 man in the gren-tea group developed cancer, a rate of only 3%. In other words only one-tenth the rate of those who didn't drink green tea.


Said the scientist in charge of the study: "To our knowledge, this is the first study showing that [green tea catechins] have potent in vivo chemoprevention activity for human prostate cancer." He also said that a collaborative study involving U.S. and Italian researchers on the effect of green tea on breast and colon cancer rates is in the works.
