Background. The importance of issue is the rising incidence of allergies to volatile organic compounds, particularly in children and adults. This necessitates understanding the causes, risk factors, and methods for prevention and treatment. The purpose of the study was to clarify the relationship between the development of allergy to lipid transfer proteins (LTP) and various environmental influences, nutrition and the immune state of the body. Materials and methods. To achieve goal, the following research methods were used: content analysis of the database of medical organizations, the method of a representative sample and quantitative examination. In the practical part of the study, we used the Immuno Solid-phase Allergen Chip test. Results. The study results demonstrated adverse reactions in both children and adults with LTP allergies. Peach (Prunus persica) was identified as an allergenic product. It was found that childhood is a particularly sensitive period for the development of allergic reactions to LTP due to incomplete immune development. Additionally, the peculiarities of food allergy were investigated, taking into account its connection with antibodies and cause-and-effect relationships. Conclusions. Sensitization to lipid transfer proteins occurs in various groups, including children and adults, and depends on the sources of exposure.
