Reaction to a food.: People can become allergic to many substances including certain foods. Some foods are more likely, such as milk, egg, wheat, soybean, shellfish, peanut, or nuts. Reactions can range from rash and itching to anaphylactic shock.
Dr. Brian Novick
Allergy and Immunology 43 years experience
The body is confused: One way of looking at this is to remember the job of the immune system is to "fight off" foreign substances. With a food allergy, the body mistakenly thinks peanut or milk etc are foreign and reacts to try to protect the body.
Dr. Manav Singla
Allergy and Immunology 23 years experience
Immunologic response: A food allergy is a specific immunologic response that your body has to a food that can lead to various symptoms. This is different from a food intolerance, such as excess gas, nausea or diarrhea.
Dr. Luis Matos

If you don't look...: If you suspect specific foods that trigger itching, hives, throat swelling, intestinal cramping, diarrhea, dumping syndrome.And loss of consiousness by dropping you blood pressure you have a food allergy. This situation is very common and it would help to have allergy skin testing to figure out which ones they are.

History and testing: Food allergy diagnosis begins with a detailed history of what symptoms are occurring and when especially in relation to meals. A thorough diet history is obtained. An exam is performed. Allergy testing can be performed either through skin testing or blood tests for ige to specific foods. Neither way of testing is perfect, so food challenges are sometimes necessary. An allergist can assist.
