Stopping Tumor Cell Growth With Nutrients
"There is evidence that habitual consumption of green tea by Japanese men is correlated with a reduction in cancers, including prostate; soybean isoflavones are also associated with increased protection," noted noted Dr. K. Sakamoto of Case Western Reserve U., Cleveland recently.*

"The present study," he continued, "compared the anti-proliferative effect of 'a black tea ingredient] alone or combined with the isoflavone genistein, on human prostate 'cancer]cells. 'The black tea ingredient] alone did not result in any alteration in cell growth. When combined with genistein however, 'it] significantly inhibited cell growth ...These findings indicate the potential use of combined 'plant] chemicals to provide protection against prostate cancer."
