Study shows: Old varieties of apples can cure apple allergy

Many hay fever patients develop an allergy to apples over time. An observational study provides new insights: Regular consumption of old apple varieties can alleviate the symptoms overall, so that new apple varieties are also better tolerated.

63 allergy sufferers who showed allergic symptoms after eating an apple of a common variety took part in the study.

The most common symptoms of apple allergy are itching in the mouth, swelling of the oral mucosa, tongue or lips. Eye, nose, skin or breathing difficulties may also occur. Typically, symptoms begin 5 to 10 minutes after eating and subside after 20 minutes.

The itching of the lips improved slightly. No significant changes were observed in the symptoms “swelling of the lip” and “swelling of the tongue”.
