Abstract
Background: Picky eating (PE), also termed food selectivity, is one of the most common feeding concerns in childhood. Although often a transient developmental stage, persistent or severe selectivity may lead to nutritional deficiencies, growth impairment, and psychosocial consequences. Methods: This narrative review is based on literature searches conducted in April 2025 across PubMed, Web of Science, Embase, Medline, and Google Scholar. Articles published between 2015 and 2025 were included if they addressed the epidemiology, etiology, assessment, or management of PE in children aged 0-18 years. Additional seminal references predating this period were also considered. Results: Prevalence estimates of PE vary widely (13-50%), with peak incidence between ages two and six. Contributing factors include genetic predisposition, sensory sensitivities, temperament, family feeding practices, environmental influences, and adverse feeding experiences. Distinction from avoidant/restrictive food intake disorder (ARFID) and pediatric feeding disorder (PFD) is essential, as these conditions carry greater risk of nutritional and psychosocial impairment. Assessment relies on caregiver-report instruments, clinical observation, growth monitoring, and targeted nutritional evaluation. Effective management integrates parental education, responsive feeding strategies, repeated exposure to novel foods, and, when indicated, nutritional supplementation or referral to multidisciplinary teams. Sensory-based therapies, behavioral interventions, and psychoeducational programs show particular benefit in persistent cases. Conclusions: While most children outgrow PE without adverse outcomes, a subset remains at risk of long-term nutritional compromise and psychosocial difficulties. Early recognition, family-centered guidance, and evidence-based interventions are essential. Future research should refine diagnostic criteria, develop culturally sensitive assessment tools, and evaluate innovative therapies to improve outcomes.
