Plant source of vitamins

Mushrooms are high in nutritional content. They're low in calories and high in fiber and protein (especially on a plant-based diet). Mushrooms also include a variety of vital elements, such as B vitamins, selenium, potassium, copper, and (when exposed to sunlight) vitamin D. Even though white mushrooms are the most common in grocery shops, don't be fooled by their appearance. White button mushrooms provide the same amount of antioxidants as more colorful fruits and vegetables.

Mushrooms are one of the few non-animal vitamin D sources. Mushrooms increase their vitamin D concentration when growing and exposed to ultraviolet (UV) radiation, either from sunshine or a UV lamp. In fact, you can achieve this at home by leaving mushrooms out in full sunshine for 15-120 minutes; studies show that this simple act can result in vitamin D2 levels as high as 10mcg per 100g fresh weight.
