Food allergies are a growing concern for many people, as the prevalence of allergies to certain foods continues to increase. A food allergy is a condition in which the immune system overreacts to a particular food protein, causing a range of symptoms ranging from mild to severe. These symptoms can include hives, itching, respiratory distress, and in extreme cases, anaphylaxis. There are several different ways to test for food allergies, including skin prick tests, blood tests, elimination diets, and oral food challenges. Skin prick tests involve exposing the skin to a small amount of the allergen and measuring the skin's reaction. Blood tests measure the level of allergen-specific IgE antibodies in the blood, while elimination diets involve removing the suspected allergen from the diet and monitoring any changes in symptoms. Oral food challenges involve gradually introducing the suspected allergen in a controlled environment, in order to determine if a food allergy is present. It
