What are button mushrooms?

Button mushrooms generally look like tiny umbrellas, having a dense parasol-like cap attached to a stem that can be short and thick or thin and slightly curvy. There are three different types of button mushrooms -- white mushrooms, crimini mushrooms, and Portobello mushrooms -- all of which share the same scientific name, Agaricus bisporus. The white mushroom, the most common type, is the cream-colored mushroom that often adorns salads and is usually one to three inches across. It has a mild earthy flavor with a meaty texture. The crimini mushroom, which looks just like the button but is coffee colored, features a more distinctive and stronger flavor. The Portobello mushroom, whose large size, up to 8 inches across, and meaty flavor make it a wonderful vegetarian entre, is actually an overgrown crimini mushroom.

Button mushrooms are grown on straw-based compost in a controlled environment that is kept warm, moist, and dark, as well as free of other fungi that may parasitize the mushrooms.

d minerals to fiber and herbal remedies, these supplements are not regulated in the same way as either food or medicine. Some of them are backed by solid research, others are folk remedies or proprietary cures. If your diet does not include enough of certain vitamins or minerals, a supplement may be a good idea. Natural treatment for conditions like constipation may be effective. But because these substances are unregulated, it is always a good idea to educate yourself about the products and to use common sense when taking them. This is even more true if you are pregnant or taking a medicine that may be affected by supplements.
