[^_^] Supplements for Nasal Allergy and Sinus Infection Patients

^_^ has posted a new item, 'Supplements for Nasal Allergy and Sinus Infection
Patients'

Nasal allergy is a quite common illness that everybody can have it. It is
caused by the exposure of the individual to the various types of allergens such
as pollen, fungus, mold, dust mites, certain foods, latex, animal dander,
volatile chemicals and others. When allergens were inhaled into the nasal
cavity, it penetrated mucosal membrane and came to contact with blood serum.
Individual with Immunoglobulin-A antibody deficiency will easily let the
allergens penetrate mucosal barrier because deficiency of Immunoglobulin-A
antibody increases the mucosal permeability. Macrophages are the first type of
cells that will come in contact with the allergen particles and after processing
the allergens; it will pass information about the invasion of the allergen
particles into the body to B-lymphocyte cells (one type of the white blood
cell). This will stimulate B-lymphocyte cells and cause them start to multiply
and transform into plasma cells. Stimulation of the B-lymphocyte is controlled
by T-lymphocyte cell (the other type of white blood cell). The plasma cells that
have been formed will produce IgE antibodies, which after that bind with the
mast cells and basophil cells around nose and cause itching and hypersensitive.
Subsequently, histamine chemical will be released from the mast cells when the
mast cells started degranulatingWhat we know that why an individual?s nose
easily becomes allergy is due to the deficiency of Immunoglobulin-A antibody,
which is one of our defense components in our body. Its function is scavenging
of exogenous material, which is coming in contact to the mucosal membrane. Apart
from this, T-lymphocyte cells, which are developed in bone marrow, work as
helper and suppressor to the secretion of immunoglobulin by the B-lymphocyte
cells. Malfunction or deficiency of these cells will cause over secretion of
immunoglobulin-E antibodies. This may exacerbate the nasal allergy illness. All
this malfunction and deficiency may due to the genetic disorder inheriting from
our parent. However, it may also cause by our irregular lifestyle, unhealthy
eating habit and environmental factor such as not enough sleep, eat too much
fried food, smoking, alcoholic, exposure to hazardous chemicals and so on.
Infection with certain virus such as HIV or utilized certain steroid or
chemotherapy medicines may also cause this problem. In other words,
deterioration of the body immune system will make nasal allergy illness become
more critical. Due to this, in order that one can relieve from the nasal allergy
torturing, he or she must have a strong immune system to defend the foreign
substances that will enter into their body.Deterioration of immune system mostly
due to the attack by the free radicals that have formed in our body. Free
radical is a very reactive molecule and has a strong tendency to oxidize lipid,
protein and DNA in our body. Everyday, a lot of free radicals are produced in
our body. Although our body itself can generate antioxidant to protect
ourselves, it is still not enough. That's why, we are all aging. Free radicals
that have been generated in our body can weaken our body immune system by
attacking to the white blood cells. Changing the DNA in a white blood cell is
the most crucial point because it causes irreversible mutation of the cell. Due
to this, white blood cells can not function properly and become malfunctioned.
When this happening, nasal allergy illness will emerge in our body. To protect
our body from radical and maintain our body immune system, we need to take
enough antioxidant supplements to neutralize the excessive free radicals that
have been produced in our body everyday.Vitamin C is the most common antioxidant
that can relief nasal allergy symptom. But the doses that we need to take to
stop the nasal allergy are around five to eight gram. This is quite a large
amount and it may cause stomach and intestinal upset. To prevent this, we should
use ascorbate form of vitamin C. Until now, there is no solid evidence to show
how vitamin C can stop the nasal allergy reaction. But scientists figured out
that it may due to its antioxidant capabilities, which prevent cell damage.
Research had been carried out in the department of obsterics at Methodist
Hospital in Brooklyn to study vitamin C and histamine levels in the blood of 400
people. They found out that, people with high levels of vitamin C in their blood
have lower histamine levels. When 1000mg vitamin C supplement was given daily to
those with low levels of vitamin C and high levels of histamine, their hay fever
improved remarkably within three days. [Journal Nutrition, April, 1980]. When
large amount of vitamin C is taken, just make sure you take calcium supplement.
This is because; vitamin C in the blood will bind with the calcium in the bone
and attract them out into the blood. This calcium will be discarded from the
body through urination. This is because vitamin C is an organic acid that can
dissolve mineral in bone. To avoid this, we should take calcium ascorbate, which
is a mineral form of vitamin C.Vitamin C is very soluble in water. Therefore,
high levels of vitamin C in the blood may not be easily achieved. This is
because vitamin C easily excretes from the body through urination. More frequent
you urinating; less vitamin C can be retained in your body. Therefore, although
we take a lot of vitamin C, the actual amount retaining in the body in very
little. You may relief the nasal allergy for a while and if you want to
continually remain relief from nasal allergy, you may need to continually take
vitamin C. This situation can be seen after we have taken the vitamin C. The
urine that we excrete after one hour taking the vitamin C is yellowish color.
The color is due to the presence of the vitamin C in the urine. The following
urine may still yellowish. After the urine no longer shows any yellowish color;
that means the vitamin C levels in the blood has gone down already. Due to this,
a lot of vitamin C has been wasted. To save cost, we need to take citrus
bioflavonoids and pantothenic acid. Both of them are vitamin B complex
substances. Citrus bioflavonoids alter the body?s metabolism of vitamin C and
raising the concentration of vitamin C in certain tissue [American Journal of
Clinical Nutrition, August, 1979]. Whereas, pantothenic acid can help our body
absorbs vitamin C more easily.Apart from vitamin C and B, the second supplement
that can boost our immune system is zinc. Zinc is a transitional metal that is
indispensable in our body. Biochemical functions in our body that involves zinc
are protein synthesis, spermatogenesis, platelet reactivity and the main one is
maintaining cellular immunity. Apart from these, zinc also can prevent certain
type of cancer. Zinc deficiency mostly due to malnutrition, alcoholism,
malabsorption, liver cirrhosis, chronic renal disease, extensive burns, use of
chelating agents and genetic disorders. Our meats that contains high amount of
zinc are chicken and beef. People who try to avoid red meat due to its high
cholesterol have the higher possibility not enough zinc in their body. Zinc
deficiency can cause growth retardation, male testerone deficiency, delayed
wound healing, bullous dermatitis, diarrhea and intercurrent infection. Zinc can
inhibit replication of several viruses such as herpes simplex virus, foot and
mouth disease virus, poliovirus and rhinovirus. Zinc is very effective to treat
common cold because it prevents rhinovirus (cold virus) from binding to the
tissue surface and stabilizes the cell membranes. Subsequently, it is also
inhibiting prostaglandin metabolism and inducing production of interferon gamma,
which is a natural chemical that help body to fight infections. Study that had
been published in the Annals Internal Medicine in 1996 showed that if an
individual starts taking zinc gluconate glycine within 24 hours onset of the
common cold symptoms, it can significantly reduced the illness duration.The
third supplement that has antioxidant function is virgin coconut oil. The
difference between ordinary coconut oil and virgin coconut oil is that the later
is extracted by wet process directly from the coconut milk or meat under a
control temperature usually is 50 oC, whereas; coconut oil is obtained from the
copra by dry process, which involves high temperature or sunlight exposure for
several days. Due to the exposure to sunlight and application of high
temperature, most of the minor components such as tocopherols, tocotrienols and
polyphenols will be destroyed. This is because all these components are unstable
in high temperature. Sunlight can destroy there components because sunlight
contains a few percent of UV light, which is a high energy wave that can break
the chemical bonding in an organic substance. Recently, study had been carried
out in University Kerala in India to determine the effectiveness of the virgin
coconut oil as antioxidant enzymes in male rat [Food Chemistry, 2006]. They
found out that virgin coconut oil has more effect as an antioxidant and prevents
peroxidation of lipids compared to the groundnut oil and copra oil. Study also
had been carried in the same University to determine the beneficial effect of
the virgin coconut oil to lipid components in male rat [Clinical Biochemistry,
37, 2004]. The finding that they got is that virgin coconut oil can reduce the
levels of lipid in serum and tissues. Besides, it also can reduce low-density
lipoprotein (LDL) and increased high-density lipoprotein in the blood. This
effect may due to its high polyphenol content.Finally, what we know
immunoglobulin-A (IgA) antibodies are the main antibodies that can prevent
allergens from entering our body through nasal mucosal membrane. Therefore,
nasal allergy and sinus infection can be prevented by increasing this antibody
level in our body. Nutrients that can boost this antibody level in our body are
monounsaturated oleic acids and vitamin A. Monounsaturated oleic acids can be
found in cold-pressed extra virgin olive oil, hazelnut or filbert oil (or the
whole nuts), green and ripe olives, and almonds. Whereas, vitamin A can be found
in cod liver oil, pumpkin, cooked carrots, sweet potatoes/yams, squash and other
yellow or orange vegetableBy Alexander Chong Author of "How to cure your
