IgE antibodies are usually produced in response to parasitic infections, such as malaria. However, some people produce IgE in response to certain foods.

The first time you eat food allergens, your immune system responds by making IgE. IgE in this case acts like a molecular marker of food allergens. When you eat food again, the body will secrete IgE antibodies and other chemicals, including histamine, to expel the enemy from your body protein.

Histamine is a powerful chemical that can affect the respiratory system, gastrointestinal tract, skin, or cardiovascular system. As a result of this response, symptoms of food allergy occur. Your symptoms depend on where in the body the histamine is released. If you remove it in the ear, nose, and throat, you may feel itchy on nose and mouth, or difficulty breathing or swallowing. If histamine is released in the skin, you may develop hives or rash. If histamine is released in the digestive tract, you likely will develop stomach pain, cramping, or diarrhea.
