Vitamin D can improve the absorption of calcium and accelerate the growth of the bones for the human body. But the natural sources of it are few. According to the latest research in America, the irradiation of ultraviolet rays can increase the amount of vitamin D contained in mushroom. The researchers use an ultraviolet lamp to irradiate the fresh mushroom for 5 minutes, and a large amount of vitamin D is produced, the content of which is 8.69 times higher than the content needed by the human body every day.
