How do mushrooms benefit your heart?
A: Mushrooms are loaded with a potent disease-fighting antioxidant called ergothioneine, according to researchers at Pennsylvania State University. In fact, they report that specialty mushrooms, such as shiitake, oyster, or maitake (hen of the woods), contain about 40 times as much ergothioneine as wheat germ, which once was thought to be the best source of the antioxidant. Even common mushrooms, such as white buttons, portobello, and cremini, contain about 12 times more of the antioxidant than wheat germ.
           
Studies from Asia also suggest compounds in mushrooms, particularly maitake and shiitake, reduce the risk of coronary heart disease. They’re a good source of potassium too, which may cut the risk of high blood pressure and stroke. In fact, a 3-ounce portobello mushroom contains about as much potassium as a small banana.
           
Researchers say both raw and cooked forms provide cardiovascular benefits. So pile them on salads, on an antipasto platter, or over pasta.
