Why you need it: The vitamin A family plays a key role in immunity, reproductive behaviors, and especially vision. The A vitamins, which include beta-carotene, help the retina, cornea, and membranes of the eye to function properly.
Where to get it: The highest concentration of vitamin A is found in sweet potatoes; just one medium-sized baked sweet potato contains more than 28,000 international units (IU) of vitamin A, or 561% of your recommended daily value (DV). Beef liver, spinach, fish, milk, eggs, and carrots also are good sources.
