Why do older people develop food allergies?
Aging affects the immune system in a process called immunosenescence, which causes cells to react differently to stimuli such as foods. This change can lead to new allergic responses to foods that were previously tolerated.
What causes food allergies?
Food allergies occur when the immune system mistakenly identifies a food protein as harmful and sends antibodies to fight it. This can cause symptoms such as
- Itching
- Urticaria
- Swelling
- Diarrhea
- Anaphylaxis (severe reaction with wheezing, tightness in the throat or difficulty breathing)
According to the American Academy of Allergy, Asthma and Immunology (AAAAI), 90% of food allergies are caused by these common allergens:
- Seafood (more frequent in adults)
- Fish (more frequent in adults)
- Peanuts
- Tree nuts
- Cow's milk
- Eggs
- Soybeans
- Wheat
Most allergic reactions occur within two hours after ingestion of the offending food.

- Carry an Epinephrine Auto-injector: If prescribed, carry an EpiPen at all times.
