Why did I suddenly develop a food allergy?
Some adult-onset food allergies arise from preexisting allergies to pollen, one of the most common environmental allergens. With the body already on high alert for pollen and anything resembling it, an overzealous immune system can become even more hypervigilant and mistake proteins in fruits and vegetables for pollen.
Can you randomly become allergic to a food?
Most food allergies start in childhood, but they can develop at any time of life. It is not clear why, but some adults develop an allergy to a food they typically eat with no problem. Sometimes a child outgrows a food allergy, but that’s less likely to happen with adults.
What causes sudden allergies in adults?

The most common food allergies in adults are peanuts, fish, shellfish such as shrimp, lobster and tree nuts (almonds, walnuts, pecans and cashews).
Can you be allergic to something all of a sudden?
Allergies can develop at any point in a person’s life. Usually, allergies first appear early in life and become a lifelong issue. However, allergies can start unexpectedly as an adult. A family history of allergies puts you at a higher risk of developing allergies some time in your life.

Why does this happen? It isn’t exactly clear why allergies might develop in adulthood. Researchers believe that a severe allergic reaction during childhood , even a single episode of symptoms, can increase your likelihood of developing allergies as an adult when you’re re-exposed to that allergen at higher levels.
What causes multiple food allergies?
A person may be generally predisposed to have food allergy and be allergic to multiple, unrelated common allergens such as peanut, egg and milk. Or, a person may be allergic to multiple foods only because those foods share similar proteins.
How do you find out what food allergies you have?
A blood test can measure your immune system’s response to particular foods by measuring the allergy-related antibody known as immunoglobulin E (IgE). For this test, a blood sample taken in your doctor’s office is sent to a medical laboratory, where different foods can be tested. Elimination diet.
Why do we develop food allergies?
The body’s immune system keeps you healthy by fighting off infections and other dangers to good health. A food allergy reaction occurs when your immune system overreacts to a food or a substance in a food, identifying it as a danger and triggering a protective response.
Can you develop food allergies as an adult?
48\% of the adult population with a convincing food allergy reported getting at least one as an adult. (They may have had others as a child.) But one out of 4 adults with a food allergy reported getting their first allergy in adulthood.
