Researchers Old apple varieties can cure apple allergy

Study shows: Old plant species can cure apple allergy

Many hay fever patients develop an allergy to apples over time. New findings provide an observational study: The regular consumption of old apple varieties can alleviate the symptoms overall, so that new apple varieties are better tolerated again.

The obser- vation study shows that the regular eating of low-allergen apples seems to allow tolerance development. Apple allergy sufferers should, if possible, access apples when buying apples.

With this observational study, the researchers were able to show that it makes perfect sense to try to find and buy old apple varieties such as Alcmene, Eifeler Rambur, Goldparmäne Gravensteiner, Jonathan and Boskoop in an apple allergy, as a regular consumption after the Study is able to not completely eliminate the existing apple allergy, but to significantly reduce the complaints when eating apples.

What is an "apple allergy"??

• An allergy to allergens in the apple
• The symptoms are varied: Itching and burning on the lip, in the mouth, on the tongue, swelling of the tongue, the oral mucosa, pharynx, suffocation, runny nose, itching of the nose or eyes, itching and wheal of the skin (as after nettle contact) , Difficulty breathing, even diarrhea and nausea.
• Most symptoms appear about 5-20 minutes after eating an apple (or hazelnuts or other stone and pomaceous fruit) and last for 1 - 2 hours.

What is the cause of an "apple allergy"?

• The prerequisite for an allergy to apples and other pome and stone fruit as well as hazelnuts is - as a rule - the existence of hay fever through the pollen of hazel, alder and birch.
• It is a kind of "floor change" from the nose and eye to the mouth.
• Responsible are allergens in the apple that are similar to the allergens in birch pollen; i.e. is spoken of a "cross-reactivity".

The study was attended by 63 allergic persons who had allergic symptoms after eating an apple of a common variety.

The most common symptoms of apple allergy are itching in the mouth, swelling of the oral mucosa, tongue or lips. It can also cause eye, nose, skin or difficulty breathing. The symptoms usually start 5 to 10 minutes after eating and clear after 20 minutes.

The study showed that after eating a Golden Delicious apple before and after the daily consumption of a low-allergenic apple over 90 days, the symptoms of the allergy, such as tingling / itching in the mouth, swelling of the oral mucosa, significantly improved. Slightly improved the itching of the lips. No significant changes were observed in the symptoms of "swelling of the lip" and "swelling of the tongue".
