Shiitake mushrooms are one of the most popular mushrooms worldwide. They are prized for their rich, savory taste and diverse health benefits. Compounds in shiitake may help fight cancer, boost immunity, and support heart health.

Shiitake are edible mushrooms. They’re tan to dark brown, with caps that grow between 2 and 4 inches (5 and 10 cm). While typically eaten like vegetables, shiitake are fungi that grow naturally on decaying hardwood trees.
