A food allergy is an exaggerated immune response to certain proteins present in food. If the body senses a protein as an allergen and deems it threatening, it creates antibodies to fight it, creating a response to the allergic reaction to food. The allergic response is of two types: IgE Mediated: IgE is a type of antibody (protective Y-shaped immune protein) created in the body. In an IgE response, histamines, an inflammatory molecule, are released to fight off the perceived invader (aka the food allergen). This triggers a typical allergy response. Non-IgE Mediated: This type of immune response involves other parts of the immune system that are not the IgE antibody, resulting in allergy symptoms in the stomach.
