What is soy allergy?

Also known as: soybean allergy, food allergy.

Food allergies are when a person develops allergy antibodies (IgE antibodies) to a protein in a food, and when exposed to this protein it causes an allergic reaction. If a person has an allergic reaction after ingestion of soy protein, this is known as a soy allergy.
