Abstract The general mortality rate from NCDs in Ukraine exceeds that in European Union countries, (Yurochko et al., 2023) exacerbated by the ongoing war. Healthy nutrition plays a pivotal role in enhancing the overall quality of life and curbing the prevalence of non-communicable diseases (NCDs). Despite its significance, ensuring healthy eating habits, particularly during the early stages of life at the period of setting lifelong habits (Jackson et al., 2020; Riley et al., 2018), remains a challenge. Besides, school-based settings represent an ideal environment for effective intervention because they offer a shared common physical, academic, and social space (Tapia-Fonllem et al., 2020). Through a series of semi-structured interviews with key stakeholders, this study identifies barriers and facilitators to policy implementation, with a focus on educational institutions. Qualitative analysis reveals barriers such as inadequate human resources, funding constraints, resistance from the food industry, and ineffective communication strategies at the family level. Moreover, there exists a disjointed understanding of nutrition standards. However, collaborative efforts with civil society, empowerment of nursing roles, strategic utilization of grants and fundraising, engagement with the food industry, and the adoption of a family-oriented approach emerge as crucial enablers for successful policy implementation. These findings offer theoretical foundations for fostering healthier nutrition environments within schools. This research serves as a roadmap for policymakers and educators striving to create sustainable and effective strategies for promoting healthy eating among early school-age children in Ukraine and beyond. Study finds human resource shortages, funding constraints, and food industry resistance as major barriers to school nutrition policy. Recommendations include collaborative approaches, nurse involvement, and aligned standards for effective school nutrition policy.
