Food Allergy Overview

    What is a Food Allergy?

    A food allergy occurs when a person’s immune system identifies proteins in a food as allergenic and begins to produce antibodies – called Immunoglobulin E or IgE – to guard against that food (e.g. shellfish or peanuts).

    Signs and Symptoms of Food Allergy

    Do you sometimes feel sick to your stomach not long after eating? Have you noticed a pattern in the types of food you eat when this occurs? Perhaps you have experienced unexplained skin rashes (known as hives) or vomiting or diarrhea? Does your child refuse to eat a certain food, or complain that it makes his “tongue hurt”? These could be signs of a food allergy, and should be taken seriously.
