An apple a day may keep the doctor away, but when it comes to your heart health, eat a pomegranate, too. The juice of the deep red fruit seems to keep fatty deposits from forming on artery walls. Researchers tested pomegranate juice’s effect on mice bred to have high cholesterol and on human heart cells isolated in a lab. The juice reduced the rate of plaque buildup in the mice by 30 percent and increased by 50 percent the heart cells’ production of nitric oxide, a substance that aids healthy blood vessel function. Pomegranates are also a good source of potassium, vitamin C and other antioxidants.
