Serious Food Allergies Can Begin in Adulthood

You bite into an apple and suddenly your mouth starts tingling. Or you eat shrimp for dinner and get hives.

A number of conditions could be the cause, but one is adult-onset food allergies. That's becoming allergic -- sometimes seriously so -- after reaching adulthood.

Researchers don't know for sure why some people become allergic to certain foods after adulthood, but there are several theories about triggers as well as possible remedies.

More than 50 million Americans have food allergies, which happen when a person's immune system overreacts to something in a food.

That includes about 10% of adults, according to Gupta's own research. Some allergies carried over from childhood, but nearly half of those began during adulthood.

About 38% in the 2019 study of 40,000 people reported having a severe reaction to food that sent them to the emergency room.

While you can be allergic to anything, nine substances cause 90% of food allergies: peanuts, tree nuts, milk, egg, shellfish, fin fish, soy, wheat and sesame.
