The ode to vitamin A
What we know about vitamin A? If as we remember from school lessons of biology, just that the shortcoming causes it a disease with the name known in the people as “night blindness“ (inability to see in the dark).
I it is valid, this major element exerts huge impact on work of organs of vision, including on visual acuity in twilight and on color sensation. However, on it functions of vitamin A in an organism and adults and kids far do not come to an end.
Vitamins of group A participate in processes of maturing and development of cages of an epithelium which covers mucous membranes of our organism, - respiratory and urinary tract, skin, eyes of a digestive tract, kidneys. It is very important that vitamin A provides the normal growth of the child, regulates exchange processes, increases organism resilience to infections and normalizes tissue respiration.
Vitamin A, unlike other vitamins, has property to collect in a human body. However you should not think that gipovitaminoz and avitaminosis of this vitamin do not exist.
On the contrary, this problem is very actual, for example, for strict vegetarians who cannot receive this important element in “a ready look“, and fill it with the vegetables and fruit rich with carotene insufficiently, - the predecessor of vitamin A.Shortage of vitamin A can lead
to serious violations in an organism of any adult and furthermore the kid. In case of insufficient amount of vitamin B the first stage sight violation, decrease in resilience of an organism to infectious diseases and delay of growth at children is noted. Also defeats of epitelialny fabrics, including skin which becomes inclined to dryness, a furunkulez are possible. At insufficiency of vitamin A predisposition of children to rhinitises, bronchitis, pneumonia and other diseases is also characteristic, the epithelium (cover) of a gastric path and urinary tract can be surprised, develop an inflammation of integuments, mucous membranes and a cornea of an eye.Therefore it is very important
that this vitamin daily got to an organism of yours of the baby. The kid about one year needs to receive every day vitamin A in number of 400 mkg, after a year and till three years - 450 mkg, and after three years - 500 mkg.
In a “ready“ look this vitamin comes to our organism with products of an animal origin, especially with a liver and kidneys, cod-liver oil, butter, milk, sour cream, cream, cheese, eggs.
Vitamin A, unlike vitamin C and other vitamins, is steady against temperature, but is sensitive to light and oxygen therefore oil, sour cream, cream and fats it is necessary to store in the closed container. Being oxidized, these products lose the nutrition value.
Vitamin A gets to us and in the form of pro-vitamin - the carotene which is present at vegetable products which the organism processes into vitamin A. Carrots, parsley, spinach, a sorrel, a celery, tomatoes, apricots, a sea-buckthorn, red pepper differ in the high content of carotene.will not prevent to give
in order to avoid a lack of vitamin A at least several times a week to the baby, grated carrot. And that he did not refuse the “vitamin“ dish prepared for it, add grated apple or other fruit to carrot gruel. Not only that vegetables are vitamin-rich, they also contain vegetable fibers, including pectins which promote work of intestines.
to exclude probability of gipovitaminoz at the kid, add special polyvitaminic complexes to his food. However, it is possible to do it only after consultation with the doctor. 1 dragee which needs to be given to the child every day or every other day (depending on a preparation and appointment of the doctor) will be a sufficient preventive dose. From domestic complexes, (which differ from foreign unless in the price), it is possible to use, for example, such as “Geksavit“, “Undevit“, “Revit“, “Komplivit“, “A gold sphere“ and others. Absolutely babies who will not be able to swallow a dragee can buy vitamin complexes in the form of syrup, and children will be more senior with pleasure to eat vitamins B chewable tablets, pastils and fruit-paste sweets.
