What is a food allergy?
A food allergy is a reaction of the body’s immune system that generally occurs soon after eating certain food. Some people experience severe reactions known as anaphylaxis, which can be dangerous and even life threatening if left untreated. Although there is no cure, it is possible that some children may outgrow their food allergy as they get older.
How fast can you have an allergic reaction to food?
Food allergy symptoms can develop within minutes of consuming the food or can take several hours to advance.
Food Allergies vs. Food Intolerance
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.
An allergic reaction to a particular food may be uncomfortable but not necessarily severe. For other people, an allergic food reaction can be frightening and even fatal.
