Mushroom: Edibility and Nutritional Properties

Mushrooms are not very nutritious in terms of energy value, since they are about 90 per cent water, very low in fat, and have most of their carbohydrates in the form of indigestible chitin. But they do contain useful protein (1–3 per cent depending on the species), and vitamins of the B group and certain others. For example, cultivated mushrooms have a little of vitamins C and K. The chanterelle owes its yellow colour to carotene, which yields vitamin A, and also contains vitamin D.
