## Abstract

The rising prevalence of food allergies, particularly to peanuts and tree nuts, poses significant challenges for pediatric health worldwide. These allergens are among the leading causes of severe allergic reactions, including anaphylaxis, often manifesting in early life. This review synthesizes the current knowledge on the immune mechanisms underlying these allergies, emphasizing the interplay between genetic, immunologic, and environmental factors in shaping allergic sensitization. Advances in prevention strategies, including early allergen introduction, have been critically evaluated. Predictive and diagnostic methodologies, from traditional IgE evaluation to cutting-edge proteomics and metabolomics approaches, have been explored to identify biomarkers that predict allergy onset and severity. By unraveling early immunological and molecular signatures, this study aimed to summarize the early prediction, prevention, diagnosis, and treatment of peanut and tree nut allergies, ultimately contributing to more effective interventions and a better quality of life for affected children.
