Nutritional payload in mushrooms

Mushrooms are the only natural fruit or vegetable source of vitamin D. They've got a lot of other things going for them too. They're a good source of copper, potassium, selenium and the B-vitamins niacin, pantothenic acid and riboflavin . They also contain ergothioneine, a potent antioxidant, in amounts greater than those found in chicken liver and wheat germ, the other two richest sources. They're fat-free, cholesterol-free and very low in calories.
