The Dire Effects of Vitamin A

As a means of being aware of you
not to fall trapped to this situation of getting into mess of getting
the sickness of vitamin A deficiency best knows how to avoid that to
affect you.  Well to those of you who weren’t
that much aware of what basically Vitamin A is then, let me be your
knight shine in armor by saying that vitamin A is a compound also known
as Retina more to those who are in the medical fraternity . it is being
defined as a vitamin that is needed by the retina of the eye in the form
of a specific metabolite, the light-absorbing molecule retinal, that is
necessary for both low-light (scotopic vision) and color vision.
Vitamin A also functions in a very different role as an irreversibly
oxidized form of retinol known as retinoic acid, which is an important
hormone-like growth factor for epithelial and other cells. Well like the
headline says, my plan is to dwell more into the deficiency that can be
caused if one don’t take the required amount of foods that will ensure you don’t
get that chance of being a statistics that is being counted as those
who are suffering from that condition. The way this condition is so
endemic, Vitamin A deficiency is estimated to affect approximately one
third of children under the age of five around the world. It is
estimated to claim the lives of 670,000 children under five annually.
Approximately 250,000–500,000
children in developing countries become blind each year owing to
vitamin A deficiency, with the highest prevalence in Southeast Asia and
Africa. Vitamin A deficiency can occur as either a primary or a
secondary deficiency. A primary vitamin A deficiency occurs among
children and adults who do not consume an adequate intake of provitamin A
carotenoids from fruits and vegetables or preformed vitamin A from
animal and dairy products. Early weaning from breastmilk can also
increase the risk of vitamin A deficiency.

Secondary vitamin A deficiency is
associated with chronic malabsorption of lipids, impaired bile
production and release, and chronic exposure to oxidants, such as
cigarette smoke, and chronic alcoholism. Vitamin A is a fat soluble
vitamin and depends on micellar solubilization for dispersion into the
small intestine, which results in poor use of vitamin A from low-fat
diets. Zinc deficiency can also impair absorption, transport, and
metabolism of vitamin A because it is essential for the synthesis of the
vitamin A transport proteins and as the cofactor in conversion of
retinol to retinal. It is no wonder you find this condition in
malnourished populations, as the common low intakes of vitamin A and
zinc increase the severity of vitamin A deficiency and lead
physiological signs and symptoms of deficiency.

That
is just a stern warning and do trust that you will be able to make

Vitamin A Supplement Benefits

We can all benefit from the vitamin
and if we consume the right dosage then we can stay in a healthy state
and keep it that way. Vitamin A, also called retinol, helps your eyes
adjust to light changes when you come in from outside and also helps
keep your eyes, skin and mucous membranes moist. Vitamin A mostly comes
from animal foods, but some plant-based foods supply beta-carotene,
which your body then converts into Vitamin A. It also has antioxidant
properties that neutralize free radicals in the body that cause tissue
and cellular damage. Eating a normal diet of foods rich in these
vitamins won’t cause a problem. Remember, you only need small amounts of
any vitamin, so you don’t
have to overdo it because that can lead to unforeseen results. In the
case of vitamin A, overconsumption has been linked with an increased
risk of fractures in postmenopausal women. So when you supposed to take
this much you should stick to it and don’t
think otherwise, you will be saving your own life. And if you have a
chronic health condition, ask your doctor about whether your vitamin
absorption will be affected. It’s always important to consult a specialist first before taking anything that might harm you at the end, so do exactly that.

And if
you want to get the most vitamins possible from your food, refrigerate
fresh produce, and keep milk and grains away from strong light.
Vitamins are easily destroyed and washed out during food preparation
and storage. So if you take vitamin supplements, store them at room

deficiency, diabetes, hyperthyroidism, liver/pancreas problems can cause
low levels of vitamin A. Vitamin A plays an important role in the body
and it is needed for growth and bone development and to maintain the
health of the skin and eyesight. Low levels of vitamin A may cause

Types of Foods that has Vitamin A

You love chewing and munching
anything that passes through your mouth and some of those foods you love
eating might have some of the most beneficial results for your
wellbeing which you would gladly love to see that taking place. Well my
initial intention roundabout here is to review about Vitamin A complex
which is hugely required in our bodies at all times because if you do
so, you will be able to keep the abreast with the ideal things that
holistically keeps you as healthy as a fiddle. Vitamin A is a generic
term for a large number of related compounds. Retinol (an alcohol) and
retinal (an aldehyde) are often referred to as preformed vitamin A.
Retinal can be converted by the body to retinoic acid, the form of
vitamin A known to affect gene transcription. Retinol, retinal, retinoic
acid, and related compounds are known as retinoid. Beta-carotene and
other carotenoids that can be converted by the body into retinol are
referred to as provitamin a carotenoids. The way it functions, this
vitamin complex it plays a vital role in the growth and repair of body
tissues, and is particularly important in maintaining good eyesight and
healthy skin, as well as aiding in bone and teeth formation. Recent
research suggests that it may also function as an anti-oxidant which its
basic function deals with the retina is located at the back of the eye. When light passes
through the lens, it is sensed by the retina and converted to a nerve
impulse for interpretation by the brain. Retinol is transported to the
retina via the circulation and accumulates in retinal pigment epithelial
cells (diagram). Here, retinol is esterified to form a retinyl ester,
which can be stored. When needed, retinyl esters are broken apart
(hydrolyzed) and isomerized to form 11-cis-retinol, which can
be oxidized to form 11-cis-retinal. 11-cis-retinal can be shuttled
across the interphotoreceptor matrix to the rod cell where it binds to a
protein called opsin to form the visual pigment, rhodopsin (also known
as visual purple). Rod cells with rhodopsin can detect very small
amounts of light, making them important for night vision.

In
terms of the foods sources, be in the know that Free retinol is not
generally found in foods. Retinyl palmitate, a precursor and storage
form of retinol, is found in foods from animals. Plants contain
carotenoids, some of which are precursors for vitamin A (e.g.,
alpha-carotene, beta-carotene, and beta-cryptoxanthin). Yellow and
orange vegetables contain significant quantities of carotenoids. Green
vegetables also contain carotenoids, though the pigment is masked by the
green pigment of chlorophyll. A number of good food sources of vitamin A
are listed in the table below along with their vitamin A content in
micrograms of retinol activity equivalents (mcg RAE). In those foods
where retinol activity comes mainly from provitamin A carotenoids, the
carotenoid content and the retinol activity equivalents are presented.

So
there you have it then guys and I kindly insist that if you would like
to pair yourself with knowledge of this kind which by the way is so in
abundance through our very own site vitamin-a.co.za to stick with this
very same site as you will just get that…which is what you have

Why Vitamin A is important?

Vitamin A is very important in
helping your body to maintain healthy cells in structures of your eyes.
It is responsible for helping your retina convert light into nerve
signals. By not having vitamin A, many eye problems could start to
develop. Some of the problems that can occur are difficulty to see in
the dark, dim light or twilight. Another problem that can be cause by
lack of vitamin A is bitot spots. These are cheese like tissue spots,
that are whitish is color, which from around your eye ball, which in
turn causes dryness in your eyes. If this is left alone and untreated,
it can eventually lead you to complete and permanent blindness. It is
also important to know that vitamin A plays a big role in the repair and
growth of body tissues. The mucous membranes of your mouth, throat,
lungs and nose also need this vitamin to protect them against possible
infection. Surely now that you have read half way through you can now

quite seriously. Without this vitamin, people, especially children would
