Vitamin A: Antioxidant Power

"Antioxidant And Antiaging Vitamin"

Vitamin A forms part of a group of compounds, which are essential for our health. The word vitamin comes from a combined latin word: "vital" which means necessary for life, and "amine" which is an organic compound. They were given this name by polish chemist Casimir Funk in 1912. Our bodies (with some exceptions) can't produce vitamins, so we need to obtain them, in small amounts from our diet.

They occur naturally in plants and animals. There are 13 of them identified, which can be divided in two groups:

water-soluble
fat-soluble

Vitamin A is a fat soluble vitamin. Our bodies can't produce it, that is why we have to obtain it from food. Our organism stores this compound in the liver. As an antioxidant it has many benefits:

Carotenoids

Have you ever wondered why carrots are orange, or tomatoes are red? Well, this is due to certain pigments called carotenoids. Carotenoids provide red, yellow and orange colours to fruits and vegetables ,and can be converted to vitamin A. The most well known carotenoids are:

beta-carotene
alpha-carotene
gamma-carotene
luteinlycopene

I'm sure you have heard some of this names before from magazines or tv programs.

There are around 600 identified carotenoids. Some of this are converted to provitamin A compounds, meaning that they are converted to retinol, which is an active form of vitamin A. The most effective is beta-carotene.

Carotenoids have important antioxidant properties, and can help in the prevention of:

cataracts
heart disease
some forms of cancer
cholesterol
aging skin

So it make good sense to eat fruits and vegetables, with a high level of carotenoids. For information in foods containing vitamin a, click in this link skin vitamins
