Whether you love or dislike mushrooms, they offer unusual health benefits unlike any other plant or animal-based foods, since mushrooms fall into the entirely distinct fungal food category. Among mushrooms' health properties are compounds called adaptogens.

Adaptogens are thought to be used by the body in whatever way it requires, unlike other fixed nutrients serving just one purpose. Along with being a great source of fiber, these adaptogens make mushrooms an invaluable nutrition source, regardless of cost.
