Mushrooms are highly nutritious foods containing proteins as complete and high-quality as meat, with unique compounds that boost immunity, fight infections, and may help prevent diseases like cancer and diabetes. Different types of mushroom proteins have specific health benefits, from strengthening immune systems to lowering blood pressure and fighting viruses. Scientists are finding new ways to grow mushrooms and extract their proteins for use in sports nutrition, medicines, and fortified foods, making them increasingly valuable for human health and sustainability.
