6. Beef Liver
Not everyone likes eating beef liver, but if cooked correctly, it can be as delicious as any food in this list if cooked correctly. Moreover, it has around 42 IUs of vitamin D for every 3 oz. Calf liver also tends to be milder and tenderer if that is your preference. It’s also rich in protein and vitamin B-12 which is critical for keeping your red blood cells and brain healthy.
7. Cheese
Like milk, cheese can also be a good source of vitamin D, with 40 IUs per slice. With an amazing amount of variety among them, cheese can be eaten on its own, in a burger or sandwich, added to pasta, or even combined with wine and cold cuts for those looking for pleasant appetizers in a party. Mozzarella cheese is a prime ingredient of pizza, of course, so you can’t go wrong there.
