Shiitakes have four to ten times the flavor of common white button mushrooms. In addition to their robust/pungent, woodsy flavor and meaty texture, shiitakes provide high levels of protein (18%), potassium, niacin and B vitamins, calcium, magnesium and phosphorus. They have natural antiviral and immunity-boosting properties and are used nutritionally to fight viruses, lower cholesterol and regulate blood pressure. Lentinan, an immunostimulant derived from shiitakes, has been used to treat cancer, AIDS, diabetes, chronic fatigue syndrome, fibrocystic breast disease, and other conditions with impressive results. Researchers S. Suzuki and Oshima found that a raw shiitake eaten daily for one week lowered serum cholesterol by 12%.
The shiitake flavor is intensified by drying. Dried mushrooms can be stored indefinitely and reconstituted by soaking. The texture is different from fresh log-grown shiitake, and they don.t saut well, but dried shiitakes are perfect for soups, stews, gravies and baked dishes
