Natural Compounds in Shiitake Mushrooms
Shiitake mushrooms contain various bioactive compounds that contribute to their health benefits:
Beta-glucans and their immune-boosting properties
Shiitake mushrooms contain beta-glucans, a type of polysaccharide that has immune-boosting properties. Beta-glucans stimulate immune cells like macrophages and natural killer cells, which play a crucial role in defending the body against infections and diseases.
Lentinan and its anti-cancer effects
Lentinan is another polysaccharide found in shiitake mushrooms that has been shown to have anti-cancer effects. Lentinan has been found to stimulate the immune system, prevent tumor growth and metastasis, and enhance the effectiveness of chemotherapy.
