Pomegranate
Pomegranate contains phytochemicals that act as antioxidants to protect the lining of the arteries from damage, explains Dr. Gregg Schneider, a nutritionally oriented dentist and expert on alternative medicine. A 2005 study published in the Proceedings of the National Academy of Sciences found that antioxidant-rich pomegranate juice stimulated the body’s production of nitric oxide, which helps keep blood flowing and arteries open.
