Kiss-type allergy, also known as oral allergy syndrome, is a type of allergic reaction that occurs when a person ingests certain foods that cross-react with allergens in pollen. Symptoms may include itching or swelling in the mouth, throat or lips, and may occur within minutes after eating the allergenic food. However, there are other terms or phrases that are similar to "kiss-type allergy," such as pollen food syndrome, cross-reactivity, cross-allergy, and oral allergy. These terms are used to describe the mechanism by which certain foods trigger an allergic reaction in people with pollen allergies. Awareness of common food triggers and practicing precautions such as cooking foods thoroughly can help prevent these allergic reactions.
