As you may have known already, food allergy is an unusual reaction to food that is elicited by an exposure to certain food types which then creates a response from the immune system. The reaction that the immune system eventually generates will then cause discomfiting symptoms.
Allergies to food are commonly dealt with by the avoidance of the allergy-causing food. When the allergen (the one that causes allergic reactions) has been recognized, the patient is then advised to eliminate it from his or her diet. This is achieved by revolutionizing the food prepared and reading carefully food labels on food products. A specific instruction when ordering food also helps avoid allergic mishaps when eating out.
