Green Tea & Heart Protection

December 20, 2010


Green tea catechins, dietary antioxidants, can protect against heart tissue after Ischemic (lack of blood supply) injury. The researchers developed a theory that part of the protection to heart against  injury may involve elevation of phase 2 enzyme activities.  Hearts were compared for indices of cell death, oxidative stress, and phase 2 enzyme activities. Hearts from the green tea group had a 65% to 85% decrease in markers of apoptosis, a tendency to higher total glutathione, and higher activities of the phase 2 enzymes glutamate cysteine ligase and quinone reductase. The results support a possible involvement of phase 2 enzymes in the protection by green tea catechins against myocardial IR injury.
