Thursday 16 June 2005

Foods account for 90% of allergic reactions in children are cow’s milk protein, eggs, peanut, soy, tree nuts, fish, and wheat.

Food allergy can manifest as urticaria/angioedema, anaphylaxis, atopic dermatitis, respiratory symptoms, or a gastrointestinal (GI) disorder.

  • oral allergy syndrome)

- "mixed" GI allergy syndromes (involving some IgE components and some non-IgE or T-cell-mediated components)

  • eosinophilic esophagitis
  • eosinophilic gastroenteritis

- T-cell-mediated allergic GI disorders (non-IgE-mediated)

  • dietary protein enteropathy
  • protein-induced enterocolitis
  • proctitis
