can be night blindness known as Nick tilapia night blindness occurs in people
with vitamin A deficiency as the vitamin as a major component of the pigment
rhodopsin rhodopsin is found in the retina of your eye and extremely
sensitive to light people with this condition can still see normally during

at lower levels in addition to preventing night blindness eating
adequate amounts of beta-carotene may help slow the decline in eyesight that
some people experience as they age age-related macular degeneration as the
leading cause of blindness in the developed world though its exact cause
is unknown it’s thought to be the result of cellular damage to the retina
attributable to oxidative stress the age-related eye disease study found that
giving people over the age of 50 with some eyesight degeneration and
antioxidant supplement including beta-carotene reduced their risk of
developing advanced macular degeneration by 25% however a recent Cochrane review

scientists in observational studies eating higher amounts of vitamin A in
the form of beta-carotene has been linked to a decreased risk of certain
types of cancer including Hodgkin’s lymphoma as well as cervical lung and
bladder cancer yet though high intakes of vitamin A from plant foods have been
associated with a reduced risk of cancer animal foods which contain active forms
of vitamin A aren’t linked in the same way similarly vitamin A supplements
haven’t shown the same beneficial effects current evidence suggests that
getting adequate vitamin A especially from plants is important for healthy
cell division and may reduce your risk of some types of cancer
number 3 vitamin a supports a healthy immune system having enough vitamin A in
your diet helps keep your immune system healthy and function at its best vitamin
A plays a vital role in maintaining your body’s natural defenses this includes
the mucous barriers in your lungs gut and genitals which help trap
bacteria and other infectious agents it’s also involved in the production and
function of white blood cells which help capture and clear bacteria and other
pathogens from your bloodstream this means that a deficiency in vitamin A can

back and chest these spots occur when the sebaceous
glands get clogged up with dead skin and oils these glands are found in the hair
follicles on your skin and produce sebum an oily waxy substance that keeps your
skin lubricated and waterproof though the spots are physically harmless acne
may have a serious effect on people’s mental health and lead to low
self-esteem anxiety and depression the exact role that vitamin uh plays in the
development and treatment of acne remains unclear it has been suggested
that vitamin A deficiency may increase your risk of developing acne as it
causes an overproduction of the protein keratin in your hair follicles this
would increase your risk of acne by making it more difficult for dead skin
cells to be removed from hair follicles leading to blockages some vitamin of
based medications for acne are now available with a prescription
isotretinoin as one example of an oral retinoid that is effective in treating
severe acne however this medication can have serious
side effects and must only be taken under medical supervision

healthy levels additionally a recent meta-analysis of observational studies
found that people with the highest amounts of total vitamin A in their diet
had a 6 percent decreased risk of fractures number 6 vitamin a promotes
healthy growth and reproduction adequate amounts of vitamin A in the diet are
essential for reproductive health and the healthy development of babies during
pregnancy vitamin A is essential for maintaining a healthy reproductive
system in both men and women as well as ensuring the normal growth and
development of embryos during pregnancy Bratt studies examining the importance
of vitamin A in male reproduction have shown that a deficiency blocks the
development of sperm cells causing infertility
likewise animal studies have suggested that vitamin A deficiency and females
can impact reproduction by reducing egg quality and affecting egg implantation
in the womb in pregnant women vitamin A is also involved in the growth and
development of many major organs and structures of the unborn child including
the skeleton nervous system heart kidneys eyes lungs and pancreas yet
though much less common than vitamin A deficiency too much vitamin A during
pregnancy can be harmful to the growing baby as well and may lead to birth
defects therefore many health authorities recommended that women avoid
foods that contain concentrated amounts of vitamin A such as pate and liver as
well as supplements containing vitamin A during pregnancy those were six health
