There is a consistent increase in prevalence of food allergy (FA). The diagnosis of FA is based on thorough history supported by positive skin test, specific IgE (extract-and component-based), Basophil activation test (BAT) to reduce the need for Oral food challenge (OFC). OFC procedures may be conducted in cases of diagnostic uncertainty or to assess the presence or development of tolerance. Effective management of food allergy involves a comprehensive three-pronged strategy. Firstly, it includes implementing measures for avoidance and diet elimination to minimize exposure to allergens. Secondly, an emergency action plan, often involving the use of an Epipen autoinjector, is crucial for immediate response to accidental allergen exposure. Finally, the approach incorporates strategies to induce tolerance through a combination of oral immunotherapy (OIT) and the use of biological agents like Omalizumab etc.. This updated review provides a practical and comprehensive approach to the diagnosis and management of food allergies
