Oyster mushrooms are low in fat; yet rich in fiber, protein, potassium, vitamin B-6, folate, iron and niacin.
Mushrooms are one of the few foods that are plant based that can supply vitamin D. Ergosterol is found in mushrooms and it turns into vitamin D as it is exposed to ultraviolet light. To enhance the vitamin D content of your mushrooms, set them in the sun for an hour before cooking. Oyster mushrooms and other fungi are the only sources of ergothioneine, which functions as an antioxidant and lowers systemic inflammation.
These Oyster mushrooms are grown on synthetic logs, produced with hardwood sawdust, soybean hulls and water. The ingredients are put into a special bag with porous filters that allow for proper gas exchange for the fungus. Once the substrate has been fully colonized by the mycelium, it is then placed into a fruiting trailer and allowed to develop mushrooms.
