Allergic reactions occur when your body responds to
 allergenin certain foods or the environment in a specific way. If you have an allergy, your immune system sees that substance as harmful and has a mild or severe responseA mild symptom might involve an itchy mouth, while a more severe one might include difficulty breathing. Keep reading to learn about the most common food allergies, how to avoid your food triggersand steps to take if you have an allergic reaction. 


Most common food allergies 
 

While many foods can cause allergic reactions, these are some of the most common:  

  • Eggs 
  • Fish (bass, cod, flounder) 
  • Milk 
  • Peanuts 
  • Shellfish (crab, lobster, shrimp) 
  • Soybeans 
  • Tree nuts 
  • Wheat 

It is important to check food labels for these major allergens or other ingredients if you or your child has a known or suspected allergy. This will reduce the chances of an allergic reaction and perhaps give you and your family peace of mind when enjoying your food.  

Tip: It’s also a good idea to tell your waiter or waitress about your food allergy if you’re eating at a restaurant or getting takeout. If you are at a holiday celebration or get-together, ask the host about the different food ingredients so you can stay safe and have a good time!

If you eat the food you’re allergic to or discover a reaction after eating a food for the first time, you may experience some of the following symptoms within minutes or hours: 

  • Coughing and/or wheezing 
  • Diarrhea 
  • Difficulty breathing  
  • Dizziness and/or lightheadedness 
  • Face, tongue, or lip swelling

When to see a doctor 
if you have an allergic reaction 

If you think you may have a food allergy, it’s important to see a doctor for care, evaluation, and testing 

Though many food allergies first appear in young children, people can discover or develop food allergies at any stage of life so be sure to seek care if you have any concerns.
