					Against Food Allergies?
Never experienced swelling redness, and itching after eating delicious food? Or even to feel
claustrophobic? If so, chances are you have a food allergy. Although the number of events a little, but
food allergies should also be considered because its effects can lead to fatality. Food allergy is an
abnormal response to a food triggered by the body's immune system. Allergic reactions that occur can
cause serious adverse events.


Mechanisms Allergic to Food
Body affect the incidence of immunological reactions to food allergies. This reaction involves the
immunoglobulin, which are proteins that help the body's immune response, rather Imonuglobulin E (IgE)
that make up the body's immune response. Immune responses that appear in allergic reactions through
two stages, namely stage allergen sensitization and elicitation phase.


Sensitization Phase
Sensitization phase occurs when the body produces antibodies specific IgE. Sensitization phase is also
called the induction phase, the first contact with an allergen (ie when consuming food allergens).


Elicitation phase
Elicitation phase occurs when there is a re-exposure. When exposed to food (allergen) of the same, shall
be binding protein molecules in the cell mediators (basophils and mast cells cells). This elicitation phase
causes the body to secrete molecules that cause inflammation (such as leukotrienes and histamine).
Effects that arise as well as the severity of allergies is influenced by the concentration and type of
allergen, route of exposure, and organ systems are involved (eg, skin, gastrointestinal tract, respiratory
tract, and blood).

Causes of Food Allergies
In adults, the foods most likely to cause an allergic reaction is food that comes from the sea, such as
shrimp, lobster, crab. Besides seafood, nuts also cause allergies in some people. Other foods that
commonly cause allergic reactions are fish and eggs. Legumes are one of the foods that can cause an
anaphylactic reaction. In a person who is highly allergic. A small amount of allergen can cause an allergic
reaction. In a person who is less sensitive, could tolerate small amounts of foods that can cause allergies.

In children, the cause of the most common food allergies are eggs, milk, nuts, and fruit. Sometimes
allergies will disappear in children, but allergies in adults tend to settle. In addition, more common in
children allergic to cow's milk or soy milk than allergies to peanuts, fish, or shrimp. Adults and children
tend to have allergic reactions to foods are often consumed. For example, people in Japan are allergic to
rice, and in Scandinavia allergy to codfish are found compared to other places.


Symptoms of Allergies to Food

    Skin
    Allergic reactions to foods most appear to the skin. Bumps, redness, very itchy, and swollen. Even
sometimes appear in groups and out quickly. Bumps on the skin may occur alone or may be
accompanied by other allergy symptoms. Atopic dermatitis or eczema, a skin condition characterized by
itchy, betsisik, redness, can also be triggered by food allergies. These reactions usually are chronic and
appear in someone who has had a family history of allergies or asthma.
    Airway
    Asthma symptoms such as coughing, wheezing sound or difficulty breathing, due to the narrowing of
the channel pernapasam, can be triggered by food allergies, especially in infants and children.

    Symptoms of food allergies that affect the gastrointestinal tract include vomiting, diarrhea, abdominal
cramps, sometimes reddish rash around the mouth. Besides, it can also occur itching and swelling
around the mouth and throat, abdominal pain, and a lot of gas.


Other reactions to food
While other reactions associated with food are food intolerances (such as lactose intolerance, milk
intolerance), food poisoning, and poisoning reaction is not a reaction of the immune response. The
prevalence of food allergy is lower than the side reactions / side effects of the diet. Estimated that food
allergies appear as 2-5% of the population.

In infants, non-allergic reactions, usually transient reactions to some foods, especially fruits, are common.
For example, there is a rash around the mouth caused by natural acid in tomatoes and oranges, or
diarrhea due to the sugar in fruit juice or other foods that appear on several times. Another reaction is an
allergic reaction, and can be caused by foods that cause allergies when eaten again. Along with growth,
