Mushrooms: Your Newest Vitamin D Source
May 06, 2006
New research suggests that exposure to ultraviolet light could enrich growing or just-picked mushrooms with a large supply of vitamin D. This could be good news for those who do not eat fish or drink fortified milk, which are currently the major food sources of the vitamin.
Better Than Cod Liver Oil?
A single serving of white button mushrooms could contain almost nine times the daily value of vitamin D after exposure to only five minutes of UV light. This would make it a richer source than two tablespoons of cod liver oil, one of the best current sources of the vitamin.
Currently, Mushrooms Not Exposed
Current practice is to raise mushrooms indoors in the dark, which minimizes their contact with UV light; therefore, they presently contain only minimal amounts of vitamin D.
Osteoporosis, Heart Disease, Cancer
Vitamin D deficiency has been connected to osteoporosis, cardiovascular disease, and tooth loss, and an increased mortality rate for several kinds of cancer.
