1 in 10 Adults Has a Food Allergy — And Many Don’t Know It

🌎How Common Are Food Allergies in the U.S.?

Food Allergies Affect Millions of Americans

Recent U.S. data show that about 10.8% of adults — roughly 26 million people — report having at least one food allergy.
That’s more than the population of Florida and Pennsylvania combined living with the risk of allergic reactions.

Hidden Danger: The ER Connection

Among those adults with food allergies, 38% have had at least one emergency department (ED) visit at some point in their lives due to a reaction.
This highlights how unpredictable food allergies can be — even for people who believe their condition is “mild.”

The Most Common Food Allergens

In adults, the most frequently reported allergens are:

  • Shellfish (shrimp, crab, lobster)
  • Milk
  • Peanuts and tree nuts
  • Fish
  • Wheat and soy

Cross-reactivity and ingredient labeling gaps often make it difficult to avoid exposures entirely.

Why Awareness Matters

Many people mistake digestive upset or hives for “sensitivity” when it’s actually an allergic response.
Knowing your triggers — and understanding how allergens appear under different ingredient names — can make the difference between mild discomfort and a trip to the ER.
