The body rests on the delicate balance of nutrients and the necessary vitamins. If something is excluded in our body, it signals us the ways we often do not notice. As simple as acne, it can be an indicator if something doesn’t work properly. Now imagine that Vitamin C deficiency in the body. The signs can first be thin, but over time.Vitamin A, as well as other vitamins necessary for the proper functioning of the body, is a necessary trace element (vitamins needed in a small amount in the body), that is, it is not made by our bodies; We need to absorb this in the form of food, so it is an important inclusion in our diet.Of course, consumption of healthy diet is important, but when and how to consume what is equally important. Foods made in the wrong hours may have adverse results.
What is Vitamin A and why is it important
Vitamin A-is a fat-soluble vitamin, which naturally occurs in many foods. Most of us know this vitamin for its important vision, healthy immune system and growth and development of our bodies. In addition to this, it can also help in the proper functioning of our heart, lungs and other bodily organs.There are two different types of vitamin A (National Institute of Health):Vitamin A is performed: Mostly found in meat bodies, seafood and dairy products.Provitamin A carotenoids: these are vegetable pigments that include vegetable pigments that include beta-carotene, alpha-carotene and beta cryptoxan. Our bodies convert provitamin a carotenoids into vitamin A for our bodies in the gut with beta-carotene. Mostly found in fruits, vegetables and plant sources.
Why is it important
Vitamin A performs many vital functions such as:
The immune system and the integrity of the barrier
Studies have shown that important immune organs need a constant diet consumption to maintain the Vita concentration, and has previously been shown both for promoting proliferation and for the regulation of timocytes apoptosis (national medicine). It is known that it increases the body’s immune function and provides natural protection against many infectious diseases. Vitamin A plays a decisive role in creating and maintaining the immune system, it showed several demonstrations even therapeutic effects, to a certain extent, in diseases transmitted through the respiratory system, such as pneumonia, measles or contagious problems such as baby diarrhea, manual foot and mouth disease.
Vision and eye health
The concentration of vitamin A is the highest in the tissues of the eyes, reaching up to 3 millimolar in the retina (National Library of Medicine). Vitamin A has a very powerful substance that is called retinoid responsible for cell growth, differentiation and apoptosis, including embryonic development and normal eye metabolism. Vitamin A is important for the formation of a visual pigment (rhodopsin) in the retinal cells, which allows low light. Its deficiency can lead to irreversible cornea damage and even blindness.
Skin health and mucous membrane
As published in the Asian Pacific Journal of Allergy and Immunology, vitamin A is necessary for the proliferation and maturation of epithelial cells lining the surfaces of the mucous membrane. Its deficiency can aggravate the integrity of the epithelium and the ability to absorb the mucous membrane antigen. It also regulates the expression of genes in the skin, provides hydration and resistance in the body. If you lack vitamin A in your body, it can increase skin inflammation and dryness.
Growth, development and reproduction
Based on the Vitamin A study article in reproduction and development published in the National Library of Medicine, Vitamin A, through its active metabolite and retinoin, plays a major role in the development of embryan, organs and reproduction. It regulates the expression of genes important for the development of the heart, lungs and kidneys, as well as nervous and limbs.
Signs of vitamin A deficit
Night blindness: The eye’s ability to see in low light decreases over a period of time and this is one of the earliest signs of vitamin A.Bitot stains: Usually they are triangular areas Xerosed conjunctiva with a layer of foam on the surface, caused by the accumulation of keratin.Dry eyes (Xerophthalmia): Eyes may feel dry, irritated or unable to create enough tears, which can lead to further complications.And since vitamin A makes miracles for the immune system, its absence in the body can put us on the radar of infections such as respiratory infections or retention of wound treatment.
