Causes & Symptoms of Food Allergies

Food allergies arise when the immune system mistakenly identifies certain foods as harmful. Common causes include genetics, exposure, and specific proteins in foods.A food allergy is an adverse immune response to a food protein. The protein in the food is the most common allergic component. These kinds of allergies occur when the body's immune system mistakenly identifies a protein as harmful.

Although sensitivity levels vary by country, the most common food allergies are allergies to milk, egg, peanuts, tree nuts, sea food, shellfish, soy and wheat. These are often referred to as "the big eight."





There are 3 common types of allergy testing: Skin prick test, blood test, and food challenges. An allergist can perform these tests and also go into further depth depending on the result.

In order to avoid an allergic reaction, a strict diet can be followed. Healthcare providers will often suggest alternate food sources of essential vitamins and minerals which are less allergic.
