Drink up orange juice lovers! Hesperidin, an antioxidant found in the popular breakfast drink, improves blood vessel function and helps lower the risk of heart disease, according to a new study reported on by WebMD.

Hesperidin, also classified as a flavonoid, is a plant-based compound found in other foods, such as grapes, red wine, green and black teas and chocolate. Research suggests that flavonoids help repair the fragile endothelial cells that line blood vessels. When these cells breakdown, it leads to clogged arteries, a major risk factor for heart attacks and strokes.

During the study, 24 men at risk for cardiovascular disease drank either 500 milliliters of OJ every day (naturally containing 292 milligrams of hesperidin), a “dummy” drink that contained the same calories as orange juice or a dummy drink fortified with 292 mg of hesperidin.

After a month, researchers discovered that men who drank orange juice or the hesperidin-fortified drink had better endothelial cell function and lower diastolic blood pressure than men who drank beverages without hesperidin.

More OJ anyone?
