Oyster mushrooms contain ergothioneine, a unique antioxidant exclusively produced by fungi, according to a 2010 study led by Penn State food scientist Joy Dubost. The study found that oyster mushrooms have significant antioxidant properties that protect cells in the body. A 3 oz. serving of oyster mushrooms contains 13 mg of ergothioneine, and cooking the mushrooms does not reduce this level.
Oyster mushrooms also have significant antibacterial activity, according to a 1997 study published in the Journal of Agricultural and Food Chemistry. The study found that the active compound benzaldehyde reduces bacterial levels.
