Can You Be Allergic to Smell?
Even in the case of severe allergies, the aroma of the offending substance can’t by itself trigger an allergic reaction. The proteins that are responsible for it are not transferred with the smell. For example, nut allergy sufferers could smell peanut butter without worrying about experiencing breathing difficulties. It’s only when certain substances are cooked that large amounts of protein molecules from the food are released into the air. Inhaling large amounts of these fumes could trigger an allergic reaction.
