Vitamin A is a fat-soluble vitamin that plays an essential role in maintaining vision, body growth, immune function and reproductive health.
Getting adequate amounts of vitamin A from your diet should prevent the symptoms of deficiency, which include hair loss, skin problems, dry eyes, night blindness and increased susceptibility to infections.
Deficiency is a leading cause of blindness in developing countries. In contrast, most people in developed countries get enough vitamin A from their diet.
The recommended dietary allowance (RDA) is 900 mcg for men, 700 mcg for women and 300–600 mcg for children and adolescents.
The RDA provides enough vitamin A for the vast majority of people.
Put simply, a single daily value (DV) of 900 mcg is used as a reference on nutrition labels in the U.S. and Canada.
This article lists 20 foods that are rich in vitamin A, plus an additional 20 fruits and vegetables rich in provitamin A (1).

10 Vegetables High in Provitamin A
Your body can produce vitamin A from carotenoids found in plants.
These carotenoids include beta-carotene and alpha-carotene, which are collectively known as provitamin A.
However, about 45 percent of people carry a genetic mutation that significantly reduces their ability to convert provitamin A into vitamin A (2, 3).
Depending on your genetics, the following vegetables might provide considerably less vitamin A than indicated.
1. Sweet Potato (cooked)—204 percent DV per serving
1 cup: 1,836 mcg (204 percent DV)
100 grams: 1,043 mcg (116 percent DV)

How Do You Meet Your Vitamin A Requirements?
You can easily meet your requirements for vitamin A by regularly eating some of the foods listed in this article. Many foods also contain added vitamin A, including cereals, margarine and dairy products.
Since vitamin A is fat-soluble, it is more efficiently absorbed into the bloodstream when eaten with fat. Most animal-sourced foods that are rich in vitamin A are also high in fat, but the same doesn’t apply to most plant sources of provitamin A.
You can improve your absorption of provitamin A from plant sources by adding a dash of oil to your salad.
However, as mentioned above, some people have a genetic mutation that makes the conversion of provitamin A into vitamin A much less efficient (2, 3).
Because of this, vegans should take supplements or make sure to eat plenty of the fruits and vegetables listed above.
Fortunately, foods abundant in vitamin A are usually easy to come by and most are an excellent addition to a healthy diet.
