Food allergies: challenges in the management of this global epidemic

Food allergies have surged in Western countries since the late 20 th century. Despite the steady rate of food allergy prevalence since the 21 st century, anaphylaxis incidence continues to rise. Recent studies indicated that food allergies and anaphylaxis are not uncommon in the developing world, but the trend in food allergy is marked by significant regional differences and urban-rural disparity. Globally, there is a discernible pattern of evolving allergen triggers associated with food protein-induced enterocolitis syndrome (FPIES), alongside the emergence of new food allergies, such as alpha-gal syndrome. Effective management of these allergies faces numerous challenges, including a lack of comprehensive data from developing nations. The global shortage of allergists, coupled with inconsistent access to care—particularly in low- to middle-income regions where epinephrine auto-injectors are often unavailable—further complicates the situation. Addressing these issues requires enhancing training for healthcare providers and establishing standardized practices to ensure comprehensive support for individuals with food allergies. The increasing instances of anaphylaxis underscore the need for strategies that extend beyond simple allergen avoidance. Recent innovations in food allergy treatment, including allergen immunotherapy (AIT) and alternative delivery methods like oral, epicutaneous, and sublingual immunotherapy, show great promise in desensitizing patients, particularly young children. Nonetheless, there remains a pressing need for more long-term safety studies and inclusive clinical trials. This article aims to examine the evolving landscape of food allergies globally and highlight critical gaps in our understanding and management, inspiring a collective effort to improve.
