Oral Allergy Syndrome: When Seasonal Allergies Affect Your Diet

Oral Allergy Syndrome: Understanding the Link Between Food and Pollen Millions suffer from seasonal allergies, but many are unaware of a related condition: oral allergy syndrome (OAS). OAS causes an allergic reaction in the mouth after eating certain fruits, vegetables, and nuts. The symptoms, often mild, include itching, burning, and swelling. "This spring, many of my patients with oral allergy syndrome are experiencing worsening symptoms," says Dr. Rubin, MD, a pediatrician and allergist. He explains that the cross-reactivity is due to similar proteins found in both pollen and certain foods like apples, peaches, and pears. Fortunately, there's a simple solution. "Cooking or peeling the fruit reduces oral allergy syndrome symptoms because it removes or breaks down some of the proteins that cause cross-reactivity," explains Dr. Rubin. Blood tests can help identify the specific allergens, allowing for better management of symptoms. Dr. Rubin's partnership with Allergy Insider provides additional resources for those seeking more information about OAS and allergy testing.
