This is because the main allergen in birch pollen (Bet v 1), is highly cross-reactive to many plant foods Moreover, people with birch pollen allergy often develop an allergy to certain foods, including apples, peaches, celery, cherries and nuts, which causes swelling of the lips when the food is eaten. They may also be allergic to hazel and alder pollen.

The oral allergy syndrome (OAS) is caused by 'cross-reactivity' between similar proteins that are found in certain fresh foods (fruit, vegetables and nuts) and pollen (usually birch tree and grass pollen in the UK).
