Food Allergy Testing

A food allergy is an immune response when the body incorrectly identifies a certain food as a threat. The immune system creates a range of symptoms throughout the body. Some people have anaphylactic reactions, which are life-threatening emergencies.

Types of Food Allergies

There are three different types of food allergies. Food sensitivities or intolerance will also be discussed.

Nearly any food can cause an allergy, but the most common food allergens are:

  • peanuts

  • tree nuts

  • milk

  • eggs

  • shellfish

  • fish

  • wheat

  • soy

  • some fruits and vegetables

This is the most common type of food allergy. It occurs when the immune system produces the antibody immunoglobulin E (IgE). Symptoms happen within a few minutes after eating the allergen. Anaphylaxis is more common with this type of reaction.

Symptoms of IgE-mediated food allergy can include:

  • Hives

  • Swelling, especially of the face, mouth or throat

  • Itching or tingling inside the mouth

  • Trouble swallowing

  • Dizziness

  • Nausea or vomiting

  • Wheezing or shortness of breath

  • Diarrhea

  • Abdominal pain

  • Itchy eyes

  • Sneezing

Anaphylaxis is a severe allergic reaction. This is an emergency that can happen suddenly and worsen rapidly. If you see someone in anaphylaxis, give epinephrine if trained to do so, and call an ambulance immediately.

In addition to the symptoms above, a person in anaphylaxis may have:

  • Difficulty breathing, swallowing or speaking

  • Chest tightness

  • Tongue swelling

  • Dizziness or feeling faint

  • Collapse

In this type of allergy, immunoglobulin E is not involved. Instead, other immune cells cause the reaction. After eating, it can take several hours or even days for the reaction to develop.

Symptoms of a non-IgE-mediated food allergy include:

  • Red, itchy skin (but not raised hives)

  • Eczema

  • Vomiting

  • Diarrhea

  • Constipation

  • Abdominal cramps

  • Colic in babies

In a mixed reaction, a person experiences symptoms from both immunoglobulin E (IgE) and other immune cells.

Food Allergy Awareness on Halloween

Did you know that one in 13 children have food allergies?

On Halloween and beyond, you can help kids and adults with allergies stay safe. Be informed about common allergens and the signs of an allergic reaction. Do something for yourself by getting tested for food allergies or sensitivities.

The Teal Pumpkin Project

The Teal Pumpkin Project is a simple way to make Halloween fun for everyone, including kids with food allergies. Put a teal pumpkin outside your home to show that you’re offering safe, non-food treats. You can still offer candy in a separate bowl, too!

Examples of non-food treats
include stickers, glow sticks, small toys, bouncy balls, and spooky trinkets. You can buy a teal pumpkin from Food Allergy Research and Education (FARE) or make your own.
