Vitamins and Minerals

Crimini mushrooms are among the only natural food sources of vitamin D, and mushrooms are one of the few foods that contain germanium, a trace mineral that helps your body use oxygen efficiently and prevents against damaging effects of free radicals. Many mushrooms are also good sources of selenium, an antioxidant mineral, as well as copper, niacin, potassium and phosphorous. Additionally, mushrooms provide protein, vitamin C and iron. Because their cells walls are undigestible unless exposed to heat, you must cook mushrooms to get their nutritional benefits.
