When a child is diagnosed with a food allergy, they know they will deal with it for the rest of their lives. But what if you’re 30 years old?  Can you grow into an allergy? A new study sheds some light.

Peanuts, shellfish, eggs and wheat are just a few of the common food allergy culprits children avoid at home and at school. But what if you never had an allergy as a child? Could that change, down the road? The short answer is yes.

According to a study published in the New England Journal of Medicine, about one in 10 adults has a food allergy, and as many as half of them developed the allergy as an adult. The most common culprit being shellfish. 

Doctors say, even if you’ve never had a problem, listen to your body. If something always triggers a bad reaction after you eat it, that could be a new allergy.

Remember, allergies can be life-threatening, so it’s vital that you know what you’re allergic to.  

But avoiding foods you’re not actually allergic to can be expensive and inconvenient. So to be safe, check with your doctor to see if you need an allergy test. 

While one in 10 adults has a food allergy, twice as many think they do — 20 percent of adults. Some other common food allergies are milk, fish, soy and sesame.
