Health InformationBefore having a food allergy reaction, a sensitive person must be exposed to the food at least once before. It is the second time the person eats the food that the allergic symptoms happen. At that time, when IgE antibodies react with the food, histamines are released, which can cause hives, asthma, itching in the mouth, trouble breathing, stomach pains, vomiting, or diarrhea.

Related QuestionsWhat is the difference between food allergy and food intolerance?
Frequently Asked QuestionsMany people think the terms food allergy and food intolerance mean the same thing; however, they do not. A "food intolerance" is an adverse food-induced reaction that does not involve the immune system. Lactose intolerance is one example of a food intolerance. A person with lactose intolerance lacks an enzyme that is needed to digest milk sugar. When the person eats milk products, symptoms such as gas, bloating, and abdominal pain may occur.
Related QuestionsFrequently Asked QuestionsFood allergy involves a reaction of the body's immune system; food intolerance does not. Food intolerance stems from problems with digestion or metabolism-the way the body breaks down food-usually because of an enzyme deficiency. Food intolerance rarely causes life-threatening reactions, as is possible with food allergy. A common symptom of food allergy is hives on the skin.Related Questions
