• When we have a food allergy, our immune system mistakenly identifies a specific food or a substance in food as something harmful.
  • Our immune system triggers cells to release antibodies known as Immunoglobulin E (IgE) antibodies to neutralize the food or food substance (the allergen).
  • The next time when we eat even the smallest amount of that food, the IgE antibodies sense it and signal your immune system to release a chemical called histamine, as well as other chemicals, into your bloodstream.
