Shiitake mushrooms, originating from Soria, are recognized by their beige and brown cap that can reach up to 25 cm in diameter. This fungus, scientifically known as Lentinula edodes, grows on oak, eucalyptus, beech, or holm oak wood in mountainous and humid areas. They are high in fiber, mainly chitin, which helps eliminate fats and cholesterol, and contain beta-glucans like lentinan, known for its potential health benefits. Nutritiously, shiitakes are a source of B vitamins such as B2, B3, and B6, and minerals like copper and selenium that contribute to various bodily functions, including immune system regulation. Shiitake is valued for its exquisite flavor and is associated with anti-inflammatory and antioxidant benefits, with research suggesting it has anti-cancer properties and nutrients that modulate immune function, providing support against infections.
