3. Mushrooms
Mushrooms are a great source of vitamin D. Just one cup of mushrooms provides over 400 IU of vitamin D. Mushrooms also contain other nutrients like potassium and copper. They can be eaten cooked or raw and are often used in soups, salads, and stir-fries.
Some mushrooms can even provide you with more vitamin D than others. For example, the Maitake mushroom is exceptionally high in vitamin D.
