What is the definition or description of: soybean allergy?

Soy Allergy: A soy allergy is an exaggerated immune response due to exposure to soy protein. The reaction can present with typical symptoms of hives, respiratory symptoms (cough, wheeze, shortness of breath), GI symptoms (abdominal pain, vomiting), swelling, loss of consciousness, and can be fatal. Symptoms typically present within minutes to a couple hours after ingestion or contact.

Symptoms when eating: Soybean allergy means having symptoms when eating soybeans or related foods. The most common symptoms are abdominal pain, vomiting or diarrhea ; and/ or skin symptoms such as a itchy rash. Sensitization is a positive allergy test which is not the same as allergy (symptoms) since as many as 50 % of people with a positive allergy test don't have symptoms when eating the food.

Food allergy: Soy can cause food allergy symptoms such as vomiting, rash and diarrhea. Asthma and anaphylaxis can occur in extreme situations.
