Vitamin A is a fat soluble vitamin known for being good for the eyes and is found in carrots. But what is behind it?
Vitamin A is not only in carrots, but also in meat and colorful vegetables. The most amount of vitamin A is found in the liver, followed by carrots and then sweet potatoes.
There are several types of provitamins, the most powerful being beta-carotene. The Body can pull out 50% more vitamin A than from another vitamin A provitamins. If you, for example, eat a carrot your body forms it to vitamin A, then your colon forms it to retinol, which is bound to a protein in the liver and carries away by blood. People say vitamin A is good for the eyes, which is true. It is also responsible for cell formation and is overall good for growth. You also need it for reproduction and for virus and bacteria protection, because it builds a virus and bacteria barrier in the nasal mucous membranes. A man needs 1 mg and a woman 0,8 mag vitamin A per day. A pregnant woman needs 1,1 to 1,5 mg vitamin A. Symptoms of vitamin A deficiency are night blindness, blurred vision, weakened immune system, delayed bone growth and your skin and nails become brittle. If you take 3mg or more vitamin A, you have an overdose. But that normally only happens if you take vitamin A sublimeness with too much of that vitamin. In the case of an overdose you get headaches, your skin is changing, your liver gets damaged and your bone density will decrease.
That´s the reason why, we should eat more vitamin A.
