Vitamin A is a fat-soluble vitamin resistant to heat but easily altered in contact with air and light! She is stored in large quantities in the body, either in the form of retinol (its free and active form), or in the form of provitamin A (precursor of vitamin A), which the body then transforms according to its needs. The best known form of provitamin A is beta carotene.
Vitamin A is essential for many body functions because it:
- Maintains the quality of vision by participating in particular in the normal functioning of the retina. It is essential for the perception of shapes and colors and above all allows the eye to adapt to the dark.
- Participates in cell regeneration and enters into the formation and protection of skin and mucous tissues. In this sense, it also plays an essential role in healing process.
- Regulates many glands such as the endocrine glands (which produce the hormones), the sebaceous glands (which produce the sebum) and the sweat glands (which produce the sweat).
- Enhances the immune response.
- Promotes normal growth of bones and teeth.
- Beta-carotene, the best known precursor of vitamin A, is known to be a powerful antioxidant, that is to say, it helps to neutralize free radicals and thus slow down the phenomenon of natural cellular aging.
We find vitamin A in the form of retinol in animal foods including butter, dairy products, egg yolk, organ meats and fish liver oil.
Provitamin A, and in particular beta carotene, is found in colorful fruits and vegetables : carrots, apricots, sweet potatoes, leafy vegetables, cruciferous vegetables (cauliflower, broccoli ...), etc ...
Remark : The assimilation of beta-carotene is greatly favored by the presence of fatty substances during the meal!
Vitamin A was discovered in 1913 by an English researcher, Hopkins. It is the first vitamin to be discovered and it is for this reason that it carries the first letter of the alphabet!
