July 20, 2009 -- An apple a day is said to keep the doctor away, but orange juice may be good at the job, too.
An antioxidant in orange juice called hesperidin improves blood vessel function and helps lower a person’s risk of heart disease, researchers report.
Hesperidin is a plant-based compound called a flavonoid. (Grapes, red wine, green and black teas, and chocolate also contain flavonoids.) A growing body of evidence suggests that flavonoids can improve the health of the delicate cells that line blood vessels. The way these cells work is referred to as "endothelial function." Problems with these cells can lead to the development of clogged arteries, a major risk factor for heart attacks and strokes.
