EGCG also topped other antioxidants, such as BHA, BHT, and Resveratol. Antioxidants are thought to prevent cellular damage that leads to certain diseases - especially cancer. It has not been determined whether one cup per day is sufficient.
Further research is needed.
In June of this year, Dr. Jerzy Jankun and associates from the Medical College of Ohio published a study in the science journal Nature that offered a possible explanation as to how green tea may work to prevent certain cancers. Green tea lovers who consume five or more cups per day are benefiting from very high levels of inhibitor. Previous studies have concluded that inhibition of urokinase can decrease or even cause complete remission of cancers in mice. Green tea may inhibit cancer formation in a number of different ways. More research is much needed in this area so that we can gain a better understanding of green teas role in cancer prevention.
