Pollen allergy beware: Christmas cookies may contain allergens

02/12/2011

The European Foundation for Allergy Research is warning pollen allergy sufferers of Christmas cookies. Often the treats contain spices and nuts that can trigger cross-allergies.

What is a cross allergy?
It is called a cross-allergy when the body is allergic to different substances, which are very similar in their chemical structure. An example of a cross-allergy is a birch pollen allergy, in which the affected person also has intolerance to nuts and tomatoes.

Especially pollen allergy sufferers are at risk
Prof. Dr. med. Torsten Zuberbier from the European Foundation for Allergy Research (ECARF) reports: „ Especially pollen allergy sufferers have to be careful when eating gingerbread and similar pastries. Spices and nuts can trigger cross-allergies because they contain substances that are similar in structure to birch pollen and can cause allergic symptoms.“ As a rule, that occurs „Oral allergy syndrome“ (OAS) as an incompatibility reaction. The symptoms are unpleasant but usually harmless. There may be a tingling sensation on the tongue and throat as well as itching on the palate and ears. If there is also swelling in the mouth and throat, a doctor should be consulted.

Observe instructions on food packaging
Since 2005, the law on the declaration of ingredients prescribed in the EU has been in force. Since then, information must be available on all food packaging. Allergy sufferers should be extra cautious with unpacked Christmas cookies, since the information on the ingredients is usually incomplete or missing, the experts warn. (Ag)
