A food allergy can range from uncomfortable to dangerous. It is caused when a normally harmless substance causes our immune system to react in an inflammatory response usually on the skin or respiratory system, and when the airways constrict due to swelling, known as laryngeal edema, the condition may be life-threatening. Allergies can be caused by airborne substances like pollen and bee stings and bites of other insects, but for this piece we will confine our discussion to common food allergies.
Food allergies should not be confused with food intolerance. The symptoms may be similar, but food allergies, though usually easier to diagnose, are often more critical. A true food allergy requires the presence of Immunoglobulin E, a class of antibody found only in mammals. These antibodies react against the problematic food, and food intolerance does not exhibit the same reaction.
