What are the causes of wheat allergy?
A wheat allergy is an immune system response. Our immune system is designed to protect us from foreign bodies and pathogens (things that cause disease), such as bacteria, viruses, and toxic substances. An allergic reaction occurs when the immune system mistakes a normal or good substance for a pathogen, and attacks it. Sometimes our immune system may attack good tissues and cells in our bodies; this is called an autoimmune disease. In the cases of wheat allergy, the immune system attacks wheat proteins as if they were, for example, harmful bacteria. The body of a person who is allergic to wheat produces an antibody to a protein found in wheat, causing an allergy. When the human body has developed an allergy-causing antibody to a specific agent (an allergen), which in this case is a wheat protein, the immune system becomes sensitive to it. Whenever that person eats a protein contained in wheat, their immune system attacks it. Albumin, globulin, gliadin and gluten are classes of protein
