One of this it’s main roles is in the production of retinal.
This substance is used within the rods and the cones in our eyes to sense light.
The body cannot produce retinal without the presence of vitamin A and without retinal, our eyes would not be able to see.
Vitamin A has been known for a long time to have an effect on our normal vision.
A deficiency in this vitamin would usually result in poor eyesight.
Vitamin-A, aside from its importance to the development of good vision, is also essential in the development of the eyes, lungs, ears and heart.
Vitamin A is also needed in order to maintain healthy skin and can even be used to treat a variety of skin diseases.
It also performs a very important function in the development of the fetus as it grows.
Vitamin A helps promote the healthy growth of the different organs of the fetus and a deficiency of the vitamin in these crucial stages can affect the child in the future.
Vitamin-A can come from a variety of sources.
Retinol, which is an active form of vitamin A, is rarely found in foods.
However, chemical compounds with similar structure and belonging to the vitamin A family of compounds can be found in food.
This compound can be processed in the body into vitamin A for use.
Different foods can supply you with different amounts of the vitamin.
Vitamin A can usually be found in green leafy vegetables and foods with a natural orange pigment.
This pigment is known as carotene.
This pigment is being processed by the body and transforms it into the vitamin-A that it uses.
Such food types would include carrots, kale, spinach, papaya, sweet potatoes and mangoes.
Vitamin-A can be lost during food preparation such as cooking and storage.
It is always wise to consume vitamin a rich foods in their raw and natural state in order to get the most out of it.
There are also a lot of processed foods available that have been fortified with this vitamin to compensate for the vitamin loss during processing.
Such examples would be fortified low-fat and skim milk as well as margarine, which have been fortified to contain an equal amount of vitamin A content with butter.
Even most ready to eat and instant cereals today are fortified with this vitamin in order to keep up with the body’s daily vitamin a needs.
