Vitamin A is a fat-soluble
vitamin that's essential to maintaining good all around health. A deficiency of
vitamin A can result in a number of health problems, ranging from mild to severe
ailments. Ought to be fact, a deficiency of vitamin A is the most common cause of
blindness around the world. In order to maintain healthy vision, proper bone
growth, healthy reproduction, and normal cell division and differentiation,
individuals must take in the recommended daily values of vitamin A. This important
vitamin can also be needed for many of the body's maintenance functions, for
example maintaining the surface linings from the intestinal tracts, eyes, and
respiratory and urinary tracts.Vitamin A is also a fighter vitamin, and therefore
it aids the defense mechanisms in fighting and preventing infections.
If someone is not getting enough vitamin A in his or her diet, it is quite entirely possible that the first sign of the deficiency is going to be night blindness. Night blindness is really a tell-tale sign that the body is lacking vitamin A. Night blindness is seen as a the complete inability to see at nighttime, but in initial stages it may just be very difficult to see or for your eyes to adjust to darkness. Vitamin A deficiency may also trigger itchiness and dryness within the eyes, cornea shriveling, cornea ulceration, and the onset of Bitot's spots within the eyes. Bitot's spots are tiny floating gray circles that demonstrate up in the white part of the eyes. Vitamin A deficiency is certainly not to mess around with. Even though it is true that many of the early indications of a deficiency are treatable and reversible through vitamin A treatment, severe symptoms like blindness and tissue death are permanent and can't be aided by increased vitamin A intake.
Preventing vitamin A deficiency is almost not a daunting challenge for individuals who aren't poverty-stricken. Maintaining a healthy diet that includes vitamin A-rich foods is it takes to stave off an insufficiency. Adult men should be sure to consume 900 micro grams from the vitamin each day, while female adults require just 700 daily micro grams. Eggs, dairy, liver, some cereals (look at your labels), and dark-colored fruits and vegetables are great sources of vitamin A. In industrialized nations, vit a deficiency is a relatively scarce problem. However, children and adults in third world countries are in an increased risk for the deficiency solely since there often are not vitamin A foods which are accessible to the general population.
