Punicalagin is a compound found only in pomegranates and this compound lowers cholesterol, triglycerides and blood pressure. Because pomegranates are rich in antioxidants, they can effectively inhibit the oxidization of bad cholesterol or LDL.
It benefits the heart and blood vessels as it speeds up the process of melting away heart blockages (atherosclerosis). The antioxidants found in pomegranate are sufficient to decrease the inflammation and thickening of the artery walls. By keeping blood circulation in order, buildup of plaque is reduced therefore you get a decreased risk of heart attack and stroke. Pomegranate can also supply iron to the blood hence reducing symptoms of anemia.
A study published at the Clinical Nutrition Journal in 2004 resulted to 30% reduction in atherosclerotic plaque of heart patients with severe carotid artery blockages who were given an ounce of pomegranate juice each day for one year. The participants’ blood pressure also lowered by 12%. The participants who did not take the pomegranate juice had a 9% increase in their atherosclerotic plaque.
Included in Nutrition Reviews, an international and peer-reviewed journal, is the 2009 study on pomegranate juice as a heart-healthy fruit juice. The review supports the cardio-protective benefits of pomegranate juice.
