About Food Allergies

Food allergy is a serious medical condition affecting up to 15 million people in the United States, including 1 in 13 children. Whether you’re newly diagnosed or brushing up on the facts, learning all you can about the disease is the key to staying safe and living well with food allergies.

What is Food Allergy?

The job of the body’s immune system is to identify and destroy germs (such as bacteria or viruses) that make you sick. A food allergy results when the immune system mistakenly targets a harmless food protein – an allergen – as a threat and attacks it.

Unlike other types of food disorders, such as intolerances, food allergies are “IgE mediated.” This means that your immune system produces abnormally large amounts of an antibody called immunoglobulin E — IgE for short. IgE antibodies fight the “enemy” food allergens by releasing histamine and other chemicals, which trigger the symptoms of an allergic reaction.
