There is no cure for food allergies. Strict avoidance of food allergens — and early recognition and management of allergic reactions to food — are important measures to prevent serious health consequences. http://www.fda.gov/Food/IngredientsPackagingLabeling/FoodAllergens/ucm079311.htm
A food allergy is an adverse immune response to a food protein. They are distinct from other adverse responses to food, such as food intolerance, pharmacological reactions, and toxin-mediated reactions. Individuals with protein allergies commonly avoid contact with the problematic protein. Some medications may prevent, minimize or treat protein allergy reactions, but there is no cure.
Mild Symptoms Can Become More Severe
Initially mild symptoms that occur after ingesting a food allergen are not always a measure of mild severity. In fact, if not treated promptly, these symptoms can become more serious in a very short amount of time, and could lead to anaphylaxis.
Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. After being exposed to a substance such as bee sting venom, the person’s immune system becomes sensitized to it.
