Like humans, mushrooms convert sunlight into a usable form of vitamin D. Vitamin D aids in the absorption of calcium and phosphorus, two essential minerals for maintaining bone health and strength. Just one half-cup serving of mushrooms provides 100 percent of the recommended daily vitamin D intake.
