Nutrition Tip
Mushrooms are low in calories and fat, are cholesterol-free and are essentially free of sodium. All mushrooms contain a wide variety of essential nutrients, including B vitamins, riboflavin, niacin, and pantothenic acid.
They also contain copper and the antioxidants selenium and ergothioniene. White button mushrooms are a good source of vitamin D: one serving of 4 to 5 mushrooms provides 15 IU of vitamin D.
Mushrooms are the best source of selenium in the fruit and vegetable aisle. In the body, selenium forms an antioxidant that may help protect cells from damage. Cell damage may develop into diseases like cancer and heart disease.
Ergothioneine is a natural antioxidant found in mushrooms, with about 3 to 4 milligrams per serving.
