Food-Pollen Syndrome

Food-Pollen Syndrome, also known as oral allergy syndrome, occurs when certain proteins in fruits, vegetables, or nuts resemble pollen proteins from plants that trigger allergies. People with pollen allergies may experience allergic reactions, like itching or swelling in their mouths and throats, when eating specific foods. Common triggers include apples, cherries, and carrots in those allergic to birch pollen, and melons and bananas for ragweed pollen allergy sufferers. Cooking or peeling the food often reduces symptoms, as heating or removing the skin breaks down the problematic proteins.
