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.
Isn’t it annoying when you smell the delicious aroma of a meal only to find out that it has an ingredient to which you are allergic? Ah! The demise of every person with food allergies! It is no fun to watch other people devour food that seems so delicious but you can’t take part of the experience. How many times have you encountered comments like, great food isn’t? And sometimes you just can’t bear to admit you are allergic and just smile as if you knew how it tasted.
