20 Foods That Are High in Vitamin A

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 United States 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% of people carry a genetic mutation that significantly reduces their ability to convert provitamin A into vitamin A (23).
Depending on your genetics, the following vegetables might provide considerably less vitamin A than indicated.

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 (23).
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.
