Any time people eat, they come in contact with substances that could trigger allergic reactions. Although people can have these reactions due to many foods, just a handful of foods cause most allergies.
Foods contain protein allergens. For the majority of people, these proteins do not trigger an allergic reaction. While many foods can cause an allergic reaction, only nine common foods cause 90%Trusted Source of allergies in the United States. These are:
- tree nuts like almonds or pecans
Children most commonly experience food allergies to peanuts, milk, soybean, tree nuts, eggs, and wheat, but many children stop being allergic to foods like milk, egg, wheat, and soy early in their childhood.
Adults with food allergies typically react to tree nuts, peanuts, fish, and shellfish. When a person thinks they have a food allergy but is not sure what food they are reacting to, an allergist can recommend a food allergy test. This can be done via either a skin or a blood test.
This article looks at the different types of common food allergies, the symptoms of each allergy, and what people can do to avoid a reaction. In severe cases, food allergies can lead to a serious and sometimes fatal allergic reaction called anaphylaxis. A person experiencing this severe reaction should seek medical attention immediately. Whenever possible people should keep epinephrine on hand and use it to treat anaphylaxis immediately.
Like many food allergies, an egg allergy is common in childhood. The major proteins that cause an allergic reaction to eggs are ovomucoid, ovalbumin, and ovotransferrin.
Some people can consume baked or cooked eggs without getting an allergic reaction, but not others. Some people might also get an allergic reaction to eggs if they are allergic to the bird that laid the egg or its feathers. This is called bird-egg syndromeTrusted Source.
