Cornell University researchers say the natural antioxidants found in green tea EGCG (epigallocatechin gallate) has shown to benefit brain and heart health in a variety of studies. Their research showed levels of EGCG were "drastically reduced" in green teas brewed with tap water because levels of calcium, magnesium and iron are higher in tap water.
