Adding two cups of fruit to your daily diet can lower your risk of heart disease as much as 25 percent. “Fruit contains dozens of different nutrients that lower levels of artery-clogging fats, plus help keep your heart’s blood vessels clear and healthy,” says Nieca Goldberg, M.D., the medical director of New York University’s Women’s Heart Program. If your blood pressure starts to creep up, which can weaken artery walls, make kiwis a part of your daily fruit quota. In a recent study at Norway’s Oslo University Hospital, just snacking on a few of these tasty gems each day single-handedly cut blood pressure readings by four points. The kiwi’s lutein -- a plant compound that helps artery walls stay relaxed -- keeps your blood pressure down even when your stress levels climb.
