Food allergies typically develop during infancy and childhood. Some individuals develop them after reaching adulthood. This is known as adult-onset food allergies. Specific foods were eaten earlier in life, without an allergic reaction.
Approximately 11% of adults have food allergies. Half of the adults with food allergies develop these new food allergies in their adult years. The most common foods causing adult-onset food allergies include:
- Tree nuts
Adults who believe they may have developed a new food allergy should see an allergist. They’ll review the medical history and do appropriate testing. The allergist will recommend which foods should be eliminated and provide treatment options. This may include carrying an epinephrine autoinjector to treat anaphylactic reactions.
