Developing adult-onset allergies — from seasonal allergies to food allergies — is possible no matter how old you are. Allergies develop when your immune system mistakenly identifies a substance such as pollen, mold, animal dander, or food as harmful. That substance is referred to as an allergen.
Keeping this in view, can you develop allergies later in life?
Most food allergies start in childhood, but they can develop at any time of life. It isn't clear why, but some adults develop an allergy to a food they used to eat with no problem. Sometimes a child outgrows a food allergy only to have it reappear in adulthood. Get emergency treatment for any severe food reaction.
