Chances are you’ve tasted pomegranates in their newly popular juice form. And from a heart-health perspective, that’s probably a good thing. Pomegranate juice is rich in antioxidants (more so than other fruit juices)—just a cup daily might help to keep free radicals from oxidizing “bad” LDL cholesterol, according to a preliminary study in theAmerican Journal of Clinical Nutrition. Oxidized LDL contributes to plaque buildup in the arteries. Another study showed that drinking pomegranate juice might improve blood flow to the heart in people with myocardial ischemia, a serious condition in which the heart’s oxygen supply is compromised because the arteries leading to it are blocked.
