What are the signs and food allergy symptoms? Food allergy also known as digestive allergy (allergic action of digestive system), allergic gastroenteritis and so on, which is due to IgE-mediated and non-IgE-mediated immune response caused by some kind of food or food additives, thus led to the digestive system or systemic allergy. Not all food allergies are so obvious like nuts and peanut allergies. It may mean a problem if the following six kinds of food allergy symptoms appear.
