The allergen profile of affected individuals changes with age: milk, egg, wheat, and soy allergies are more common in early childhood and often resolve before adolescence, whereas peanut, tree nut, fish, and shellfish allergies tend to persist and become more apparent in teenagers. The aim of this narrative review is to discuss the impact of food allergy and elimination diets on the nutritional status, psychological functioning, and quality of life of adolescents. Although an elimination diet remains the main way of treatment, it may lead to the risk of vitamin D, calcium, iron, and protein deficiencies, and potentially to growth disorders. In adolescents, irregular eating habits and poor adherence to dietary recommendations pose additional challenges. The psychological burden of living with food allergy include fear of accidental contact with the allergen, difficulties in peer relationships, and reduced quality of life, particularly in terms of social and emotional functioning. Lack of training in using an adrenaline autoinjector and embarrassment about its use are further risk factors in this age group. Optimal care for adolescents with food allergies requires a multidisciplinary approach, including an allergist, dietitian, and psychologist. Education, psychological support, and gradual development of self-management skills are crucial to improving the safety and quality of life of adolescents with food allergies. Further efforts by medical societies are warranted to advance the development of alternative therapeutic approaches for food allergy, including immunotherapy and biologic therapies, as well as to strengthen public health strategies for individuals affected by food allergies.  \nKeywords: food allergy; adolescence; elimination diet; quality of life  \n1. Introduction  \nAwareness of food allergy (FA) dates back many centuries. As early as 2700 BC, Chinese records recommended that pregnant women avoid certain foods believed to cause skin lesions. In the 1st century BC, Titus Lucretius Carus wrote “What is food to one, to another is rank poison”, clearly indicating that adverse reactions to food were already recognized at that time [1] . Recent advances in medical science, technology, and nutrition research have greatly improved our understanding of how certain foods can trigger harmful reactions in the body.  \nThe prevalence of FA continues to rise worldwide. It is estimated to affect approximately 8% of children and 10% of adults in highly industrialized countries [2] . Significant regional differences are observed, and the reported prevalence varies depending on the specific food analyzed: in Europe and North America, peanut and egg allergies are the  \nmost common allergens, while in Asia, shellfish and fish allergy predominate [3] . Reactions to lipid transfer proteins (LTPs) in fruits, lentils, and walnuts are frequently reported in Southern Europe, whereas allergies to birch pollen and birch pollen cross-allergens (e.g., apple, carrot, celery, hazelnut) are common in Central and Northern Europe. Furthermore, the patient’s allergen profile changes with age: milk, egg, whea","cbCaiaKlsk81Cl72","https://ap.wps.com/l/cbCaiaKlsk81Cl72","pdf",545736,18,"English","# Abstract\n# 1.
