Most cheese contains some amount of iodine, but the exact amount depends on what type of cheese you're eating. An ounce of cheddar cheese, for example, contains 12 micrograms of iodine, which is 8 percent of the amount you need for the day. Mozzarella cheese is a good source of iodine as well, according to HealWithFood.org. Sheep and goat cheese supply iodine, too.
Cheese is an excellent source of protein (1). One thick slice of cheddar cheese (28 g) contains about 6.7 g of protein, which is similar to what you get from a glass of milk. The majority of proteins in cheese belong to a family of milk proteins called casein. Milk proteins are of excellent quality, rich in essential amino acids, and highly digestible.
