Oysters are good for your vision because they're high in zinc, plus they're a great source of protein. Zinc is an antioxidant that is important for eye health and is necessary for immune system function. It's involved in many different chemical reactions that occur in the body. If you don't like oysters, you can still get some zinc from beef or pork, although oysters contain more zinc than any other food.
Oysters have been eaten throughout history. In most grocery stores, you'll find canned oysters, but some meat departments will sell fresh, live oysters. Eat raw, smoked or cooked oysters as an appetizer or you can make oyster stew.
