Anti-Aging Research: Green Tea Stops Colon Cancer

Green tea stops the growth of colon tumors in their infancy, says a new study using mice, but merely drinking green tea offers no benefits against larger tumors.

Green tea contains between 30 and 40 percent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 percent. The four primary polyphenols found in fresh tealeaves are epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate, and epicatechin.

A large body of epidemiological data already indicates that the beverage and its extracts may offer significant benefits for lowering the risk of colon cancer.
