Mushrooms are nutritious and low in calories: They are a good source of B vitamins, especially niacin and riboflavin, and rank the highest among vegetables for protein content.
But because they are low in fat and calories, Western nutritionists mistakenly considered them of no food value (a fresh pound has only about 125 calories). Yet in dried form, mushrooms have almost as much protein as veal and a significant amount of complex carbohydrates called polysaccharides. One of the most valuable mushrooms, both nutritionally and flavor-wise, is Lentinus edodes, commonly called shiitake.
