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).

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.
