Fruit, the main cause of food allergies

Fruit allergy has increased 34% in recent years and is the most common cause of food allergy in our country followed by nuts.

Food allergies, unlike intolerances, are an abnormal response of the organism to certain foods that would otherwise be harmless, involving the immune system. The reaction can occur in minutes or a few hours.

According to the Public Declaration on Food Allergy and Anaphylaxis of the European Academy of Clinical Allergy and Immunology (EAACI), around 3% of the Spanish population (1,330,000 people) suffer from food allergy and, the same body indicates that the avoidance of food can cause physical adverse effects for people, since dietary imbalances can occur.

Also, according to the Allergy Report 2015 of the Spanish Society of Allergology and Clinical Immunology (SEAIC), fruit allergy has increased by 34% in 10 years, becoming the most frequent cause of food allergy in our country, followed by nuts. In this report, it is indicated that almost 60% of allergic reactions induced by fruits are due to lipid transporter protein called LTP, which is found in the plant kingdom.

This protein is characterized by its high resistance to digestive enzymes and temperature increase, so it acquires the ability to sensitize directly through the digestive tract. One of the first fruits with which the symptoms were described was the peach.

Allergic reactions caused by LTP are usually systemic and severe – gastrointestinal symptoms, nausea, vomiting and diarrhea, generalized or contact urticaria and also severe asthma and even anaphylaxis. Specifically, food allergy is one of the most frequent causes of anaphylaxis. However, in most cases, systemic symptoms are preceded by oral allergy syndrome (ODS), characterized by symptoms located in the mouth and throat such as tingling, tingling and swelling of the lips, throat irritation.

Treatment of food allergies

To treat allergies to LTP, until recently, in allergology, the only recommendation available was the avoidance of allergens responsible for the diet, although, for patients and their environment, this measure involves a psychosocial disorder, In addition to a possible nutritional deficit in those cases in which there are several food groups involved. Another suggestion made by allergists is specific sublingual immunotherapy, generally indicated in allergy to peach, rosacea fruits and other plant-based foods.

“In the allergic diseases the correct diagnosis and treatment carried out by an allergist specialist is key and it is a legal obligation on the part of the food and hospitality professionals to correctly label the food and its handling to avoid accidental reactions, ”said the president of the Food Committee, Monica Antón.
