Ever noticed how after you eat a pomegranate your mouth feels a little dry? That sensation comes from phenolic compounds in pomegranates called ellagitannins. These ellagitannins (and other anthocyanins and flavonoids) are antioxidants and may be why pomegranates have been shown to have 3x more antioxidant activity than green tea. Studies suggest that consuming pomegranate may increase endurance during exercise. Pomegranates have also been researched for their potential to help lower blood pressure and reduce swelling and pain in the joints.
