Can you be allergic to something all of a sudden?

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.

Can you get a nut allergy at any age?

It is possible to develop a tree nut allergy as an adult. Most food allergies start in childhood, but they can also develop in adults. It is unknown why some adults develop an allergy to a food they have previously consumed without problems. Tree nuts can cause severe, potentially fatal, allergic reactions.

What age do you develop food allergies?

A: Most food allergies develop in children 6 years of age or younger, but they can occur for the first time at any age, including in adulthood. The estimated prevalence of food allergy among American children is 5-7 percent. In adults, it is about 1-2 percent.
