Button mushrooms
Button mushrooms are mild edible mushrooms with white or brown caps. They work well in stir-fries, soups and sauces and provide B vitamins and minerals.
Common cultivated button mushrooms belong to the species Agaricus bisporus. Although they are fungi, they are used much like vegetables in cooking. You can sauté, grill, roast or stuff them; cooking brings out their savoury flavour. The nutrient table lists amounts per 100 g, together with the source.

Safety information
Contraindication
Avoid if you have a confirmed mushroom allergy
If you have a confirmed allergy to button, cremini or portobello mushrooms, avoid them even when cooked. Allergic reactions, including anaphylaxis, have been documented; cooking does not reliably prevent them. Whether you can tolerate other mushroom species needs individual assessment by an allergy specialist. [1]
Caution
Prefer cooked mushrooms
Mushrooms naturally contain agaritine and related substances. Prefer cooked mushrooms and limit raw consumption, particularly if you eat them frequently. Heating reduces these substances but does not necessarily remove them completely. A human cancer risk from ordinary mushroom meals has not been established. [2][3]
Caution
Store safely and prepare hygienically
Keep fresh mushrooms refrigerated, do not use spoiled mushrooms, and clean them under running water before preparation. Avoid contact with raw meat and cook thoroughly. These precautions are especially important during pregnancy and for young children, older adults and people with weakened immune systems, who are more vulnerable to serious foodborne illness. [2][4]
