My mouth itches when I eat fruit: is it an allergy?
There are several different proteins in fruit that can cause an allergy. Some also exist in pollens and are destroyed by higher temperatures and in the stomach and therefore only cause oral allergy syndrome, i.e. itching of the lips, tongue, mouth or throat and sometimes even slight swelling, which only happens when eating. fresh fruit (not cooked) and which usually resolves spontaneously or quickly with an antihistamine.
