Mushrooms are the only produce item that can synthesize Vitamin D from sunlight, much like human skin. 

They contain a precursor called ergosterol. 

When exposed to UV light, they convert it into Vitamin D2. 

Studies show that even "store-bought" mushrooms will skyrocket in nutrient density if you just put them on a windowsill before eating them. 

You’re essentially "charging" your food with solar energy.
