About The Study

Northwestern University scientists surveyed 40K American adults over a 2-year period. The findings:

  • Approx. 50% of adults with a food allergy developed it later in life. 
  • Adult-onset food allergies were equally common in those with & without a childhood food allergy.
  • Only half of adults with a “food allergy” had an official diagnosis.

Allergy v. Intolerance

According to Dr. Ruchi Gupta, one of the study’s co-authors, nearly 1 out of 5 American adults *believe* they have a food allergy; they most likely have a food sensitivity or intolerance.

Why do allergies start in adulthood? No one knows.
