Vitamin D Is Key to a Healthy Immune System, and These 7 Foods Have It in Spades

All mushrooms contain some vitamin D, but some varieties boast even more due to UV light or sunlight exposure. Mushroom farmers literally expose mushrooms to UV light to increase their vitamin D content!

A simple and delicious way to add vitamin D to your diet is blending finely chopped mushrooms with ground meat in dishes such as burgers, tacos, or bolognese. Swapping just 25 percent of the meat for mushrooms will reduce your calorie and fat intake, while adding nutrients like vitamin D, potassium, B vitamins, and antioxidants.
