The IgE antibody causes "classic" or "atopic" allergic reactions related to hay fever and anaphylaxis and is well-known for causing immediate allergic reactions. IgE food allergy testing reveals reactions that occur immediately after ingesting offending foods such as peanuts or shellfish.
According to the FDA, more than 160 foods can cause allergic reactions in people with food allergies. The eight most common foods accounting for 90 percent of food allergic reactions are required by law to be listed in the ingredients, and are the food sources from which many other ingredients are derived.
The eight foods identified by law which cause common food reactions are:
- Milk
- Eggs
- Fish (e.g., bass, flounder, cod)
- Crustacean shellfish (e.g. crab, lobster, shrimp)
- Tree nuts (e.g., almonds, walnuts, pecans)
- Peanuts
- Wheat
- Soybeans
