It’s not unusual for a person with seasonal allergies to own an itchy nose and itchy eyes. But it may seem surprising that some hay-fever sufferers get an itchy feeling in their mouths, throats and lips when they start to eat certain foods.

This condition is known as oral allergy syndrome (OAS) or pollen-associated food allergy syndrome, and it’s the most common form of food allergy in adults. It occurs because proteins found in some unused fruits and vegetables are similar to allergy-causing proteins found in pollens, such as ragweed, birch, mugwort and grasses.

Not endless after some people with seasonal allergies eat raw fruits and raw vegetables, as well as some nuts and spices, these people’s immune systems recognize a similarity between the food and pollen’s proteins.

This is called cross reactivity.

«The thinking in the field is that the pollen allergy is the driver behind the immune response to the food,» said Dr. Wayne Shreffler, director of the Food Allergy Middle at MassGeneral Hospital for Children in Boston.

Here are his tips for people with hay fever who may experience oral allergy syndrome.

Realize that some hay fever sufferers are not affected

OAS is «pretty common» in people with seasonal allergies, Shreffler told Live Science.
