Facts about food allergies

People who experience food allergies know their immune system is attacking their bodies. Even one bite of a forbidden food can cause symptoms ranging from hives and digestive problems to swollen airways and life-threatening anaphylaxis.

And the problem is on the rise. The National Institute of Allergy and Infectious Diseases estimates about 5% of children — a 20% increase from 20 years ago — and 4% of adults in America have a food allergy.

About 90% of all food allergies are caused by foods commonly referred to as the “big 8.” These are

  • eggs
  • fish
  • milk
  • nuts from trees
  • peanuts
  • shellfish
  • soy and
  • wheat.

Symptoms can range from mild to severe and affect each individual differently. Common signs and symptoms include

  • tingling in the mouth
  • burning sensation in the lips and mouth
  • swelling of the lips and face
  • skin rash
  • itchy and/or blotchy skin
  • wheezing
  • nausea
  • diarrhea
  • runny nose and
  • watery eyes.

For some people, diagnosing food allergies can be challenging. Finding out if you have an allergy can sometimes be as simple as having your doctor perform a skin prick or blood test, or keeping a food diary to help you find answers. Then, your work begins.

  • Remove foods from your diet.
  • Avoid inhaling, touching or eating foods with traces of the food allergen.
  • Thoroughly wash cutlery, cooking surfaces and chopping boards.
  • Read food and drink labels carefully.
  • Watch out for soaps, pet foods, glues and adhesives with traces of the food allergen.
