Food allergies
Article Abstract:
Food allergy or hypersensitivity is a moderate to severe immune response to certain types of foods. Many reactions are immediate, and are associated with the production of the IgE antibody. Surveys suggest that only 8% of children under six years old and 1% to 2% of adults have food allergy. Young children are more likely to have food allergy because their gastrointestinal tract, which can eliminate many allergens, is not completely developed. Common food allergens include cow's milk, eggs, peanuts and fish. IgE-hypersensitivity produces many of the symptoms of anaphylaxis, and can be life-threatening. Other food allergies, such as celiac disease and dermatitis herpetiformis, do not involve IgE. The best treatment for food allergy is to avoid the particular food. A severe anaphylactic reaction should be treated with epinephrine and bronchodilators.

Food allergy
Article Abstract:
Food allergies result from an immunologic overreaction to particular food proteins, and may manifest as swelling and itching in the mouth and throat, runny nose, gastrointestinal difficulty, or severe shock. Many people believe they have food allergies, but only about 1.5% of adults demonstrate symptoms in controlled medical studies. Most reactions in adults come from nuts and fish, and all reactions can be controlled with dietary avoidance. Testing with foods hidden in capsules is most diagnostic. Many people lose their sensitivity if they avoid the offending food for several years.
