3 Mushrooms
Since sunlight feeds mushroom growth, no wonder it is one of the best vitamin D-rich foods. It is one of the plant foods with high vitamin content without additional artificial fortification.
Some varieties of mushrooms contain up to 2,300 IU in a hundred-gram serving, which is almost several times the daily allowance. For example, Shiitake mushrooms are a popular source of vitamin D – even if it is a dry version. Maitake and morel mushrooms are high in vitamin D too.
However, not all mushrooms are super high in vitamin D, as well as not all mushrooms must be fresh. Those mushrooms grown under standard commercial conditions – in the dark – cannot serve as sources of vitamin D.
