Allergies

Not a bit of thought, allergic just same as autoimum diseases.In fact, the two entirely different.Allergies can occur because of external factors.For example, people get itchy from eating eggs.Allergies are inappropriate reactions to a person.These reactions are caused by contact with certain materials that should not be dangerous for people in general.Among them, the contact with food, air and direct contact with the skin.There are genetic factors that affect the allergic.Therefore, patients are rarely cured.There are some foods that normally trigger an allergic reaction.Among others, seafood, like clams, shrimp, lobster, crab, squid and fish.Other foods, some types of nuts, like almonds and peanuts.Allergic to eggs are also often encountered.Food allergy is a hypersensitive reaction.That is, before an allergic reaction to food appears, the patient never exposed to the same allergens previously.When the first time hit, allergen will stimulate the lymphocytes to produce antibody (IgE) against the allergen.
   Antibodies are attached to the mast cells of human tissue.If at any time the person ate the same food, it will send antibody mast cells release histamine.Chemical called histamine is the cause of food allergy symptoms.Symptoms may appear several minutes after eating or hours later.Usually, the form of itching.And, the material in the form of the protein allergens.Materials are not damaged during food processing.Also not damaged by stomach acid.As a result, allergen enter easily into the body and into the blood circulation.Furthermore, allergen reaches the target organ for allergic reaction.
