It is estimated that one in six men living in Western countries will be diagnosed with prostate cancer at some point in their lives, while many fewer Asian men will receive the dreaded news. While the underlying risks of developing this cancer are basically the same (a significant portion of Asian men have prostate micro-tumors), certain lifestyle differences are thought to prevent the micro-tumors from maturing into cancer. Recent studies suggest that drinking green tea on a regular basis accounts, in part, for this disparity.
One double-blind, placebo-controlled trial found a marked decrease in the rates of advancing prostate cancers. EGCG, a polyphenol found in green tea, has the ability to inhibit the function of the androgen receptor - a protein frequently found in prostate cancer cells. Some believe EGCG could prevent these tumors from progressing.
As more and more studies are being done, we will keep you posted.
