Tingling in the mouth and a feeling of fur on the tongue are the main symptoms
Mixed allergy ... suffering from pollen even bananas and apples
Some foods allergic to pollen are not tolerated, such as tomatoes, bananas, apples, and some herbs, and this phenomenon is known as a mixed allergy.
"The reasons for this are due to the presence of a match between the two sources that cause allergies, or the presence of a similar combination between them, which the immune system suddenly recognized, and therefore it responds with the similar source of allergy," said Sonya Limel, of the German Society of Allergy and Asthma.
For his part, said dermatologist, Professor Berger Kranke: "There are some people with allergies who put themselves at risk." Even if the person is aware of pollen allergy and is aware of the seasonal symptoms that he suffers, this does not mean that he is able to assess the allergic symptoms that appear after eating certain foods properly.
He added, "In some rare cases, this may lead to a state of shock."
He explained that usually mixed reactions are talked about with regard to pollen allergies and food allergies, and here the immune system does not respond to known allergens, such as pollen, house dust mites or animal hair, but it does respond to some foods as well.
If a person suffers from an allergy to birch pollen, he is at risk of developing allergic reactions when consuming apples, hazelnuts, or soy, and if a person has hay fever, he often has a response, said Kranke, who is head of the outpatient allergy clinic at the University Hospital Graz. 50% sensitivity when eating certain foods.
Meanwhile, Sonya Leimel pointed out that there has been an increase in the number of people with pollen allergy, who suffer at the same time from food allergies related to pollen grains, in recent years, and also suffer from some mixed allergy syndromes.
Birch and apple
In terms of numbers, the syndrome of birch pollen, walnuts and pome fruits is currently the most important, meaning that if the immune system responds allergic to the structures of birch pollen, it can also respond allergic to when consuming apples, plums, cherries, plums, hazelnuts, walnuts and soybeans.
In addition, celery and carrot syndrome, fire and spice grass, and house dust mite syndrome, crustaceans and mollusks are common, as eating shrimp and mussels can cause allergic problems in those with allergies to house dust mites.
Tingling and itching
The mixed response symptoms often first appear on parts of the body that come in direct contact with the allergen.
Sonia Limel explained that tingling in the mouth, itching in the throat and a feeling of fur on the tongue are among the most common symptoms, and it is also possible to have a runny nose, itchy eye or irritation in the throat.
Kranke stressed that there is rarely a significant spread of symptoms, so that the symptoms appear in other body organs, such as the lungs, skin and the whole body, or what is known as allergic shock, and mixed responses can only be avoided, except by examining and diagnosing mixed sensitivity.
Antihistamines
German doctors advise that all people with specific allergies should take antihistamines and corticosteroids, including an adrenaline auto-injector, however the most effective procedure is to avoid allergens and foods.
Sonia Limel advises following a nutritional treatment, in which recommendations are made to avoid certain foods according to each individual case, given that the allergy test shows in most cases "silent allergic responses", and this means that the test is positive due to the mixed response, but eating certain foods It triggers an allergic response.
• Mixed responses cannot be avoided, except through a sensitivity test.
