Inhibition of prostate carcinogenesis by green tea polyphenols
This was a rat study, but much evidence points to similar evidence in humans. Green tea is such a wonderful replacement for soft drinks and especially coffee. Not only does green tea not have the harmful effects, but the polyphenolenic compounds have numerous health benefits. For those who do not like tea plain, try flavoring with either lemon or stevia, an herbal sweetener.
