Food allergy is a serious and potentially life-threatening medical condition affecting 32 million Americans. One in every 13 children has a food allergy, that's about 2 in every U.S. classroom. And every 3 minutes, a food allergy reaction sends someone to the emergency room. Food allergy is among the diseases considered to be part of the Atopic March. Also known as the Allergic March, this term refers to the progression of allergic diseases in a person's life: eczema, food allergy, allergic rhinitis and asthma. Not everyone will follow this progression or experience every condition.
What Causes Food Allergies?
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 happens when your immune system overreacts to a harmless food protein, an allergen. The eight most common food allergies in the U.S. are:
- Tree Nuts
Family history appears to play a role in whether someone develops a food allergy. If you have other kinds of allergic reactions, like eczema or hay fever, you have a greater risk of food allergy. This is also true of asthma. Food allergies are not the same as food intolerances, and food allergy symptoms overlap with symptoms of other medical conditions. It is therefore important to have your food allergy confirmed by an appropriate evaluation with an allergist. Food allergies are serious. Food allergy may occur in response to any food, and some people are allergic to more than one food. Food allergies may start in childhood or as an adult. All food allergies have one thing in common: They are potentially life threatening. Always take food allergies and the people who live with them seriously. Food allergy reactions can vary unpredictably from mild to severe. Mild food allergy reactions may involve only a few hives or minor abdominal pain, though some food allergy reactions progress to severe anaphylaxis with low blood pressure and loss of consciousness.
Currently, there is no cure for food allergies.
