Produce with pollen-like proteins
If you're sneezing and sniffling, you could also have a problem eating some fruits and veggies. It's called oral-allergy syndrome (OAS), and the Asthma and Allergy Foundation of America estimates up to a third of pollen allergy patients may be affected. You can blame a protein found on the surface of some raw produce, including apples, tomatoes, and cantaloupe, though each pollen allergy has its own set of trigger foods.
"Pollen and food proteins are like first cousins," says Cliff Bassett, MD, founder of Allergy and Asthma Care in New York City. "So your body thinks you're swallowing pollen."
This usually leads to bothersome symptoms, like an itchy throat and mouth as well as cough. Peeling produce may help to reduce your reaction, Dr. Bassett says. Even cooking the produce may help. Just be careful—research shows about 2 percent of people with OAS have symptoms than can progress to potentially life-threatening anaphylactic shock, according to the Asthma and Allergy Foundation of America.
