Hi today Troosta is going to discuss

What is the importance of vitamin A?
This is a fat soluble
vitamin. It is also known as retinol, which is its chemical name. We can divide
the sources of vitamin A foods into two different types; they are known as
retinol and carotenes. Retinol can be found in the animal based food items and
carotenes can be found in the plant based foods. Now we can talks about the
importance of vitamin A in our body. Vitamin A plays a significant role in our
growth of bones. This vitamin protects our body from infections. Like fungal or virus or bacterial infections.
And it is very important for our normal vision, development, also it is
necessary for reproduction, bone maintenance and for immune functions. The lack of vitamin A caused for blindness or
some disorders of our vision, like night blindness, dry eyes, and nutritional
blindness. The deficiency of vitamin A also affects the reproductive functions.
We can prevent these situations by the regular eating of fresh carrots and
vegetables. And at the same time the excess quantity of vitamin A caused for
headaches, nausea, dry and cracked skin. It also caused for liver
diseases. It is recommended to eat
700mcg of vitamin A for women and 900 micrograms for men per day. And always
careful that there is a limitation of the value of vitamin a in our body, never
exceed 3000mcg of vitamin A in each day.
And at the time of pregnancy eating more than1000 IU of vitamin A is not
advisable. An IU or international units of retinol is equal to 0.3 microgram
and 1IU of carotenes is equal to 0.6 microgram.
Our body needs vitamin A to keep our eyes and bones etc being strong and
healthy and keep our skin, lungs and immunity healthily.
