Swiss cheese
This is another way to pick up your vitamin D, along with calcium and vitamin K, which work together to keep your bones strong. Swiss cheese is easy to shred and sprinkle over a salad, throw into veggies, or bake onto bread. Try to buy organic, raw cheeses when possible.
Egg yolk
Vitamin D is found in the yolk of the egg only. Eggs also contain all your essential amino acids and are a great source of choline and healthy fats. Always choose free-range or pastured eggs, as they contain 4 to 6 times more vitamin D.
