Treat him to green tea
by Andrew Weil, MD

Japanese men, who commonly drink 4 to 6 cups of green tea a day, have a significantly lower mortality rate from prostate cancer than Western men do; Chinese men, who also drink green tea regularly, have the lowest rate of prostate cancer in the world.

A Mayo Clinic study found that a compound in green tea, epigallocatechin-3-gallate (EGCG), inhibits the growth of prostate cancer cells.
