<![CDATA[Obesity, particularly among children and adolescents, represents a growing public health concern in Indonesia and globally, leading to increased risks of non-communicable diseases. This narrative review aims to synthesize existing literature on the impact and effectiveness of nutrition education interventions in improving knowledge, attitudes, and healthy snack consumption behaviors among school students. The review was conducted by analyzing secondary data from relevant international articles published between 2015 and 2025, obtained from databases such as Google Scholar, Scopus, and PubMed, focusing on full-text original research. Findings indicate that various nutrition education approaches, including those utilizing interactive media, Health Belief Model-based interventions, and peer education, consistently enhance nutritional knowledge. Furthermore, these programs positively influence actual eating behaviors by reducing unhealthy snack intake and promoting healthier choices, as evidenced by improved fruit and vegetable consumption and better overall snack quality. School-based and after-school programs, alongside community service activities, prove effective settings for delivery. These interventions also encourage students to develop greater awareness of the importance of balanced nutrition and healthier food choices in their daily lives. Moreover, the involvement of teachers, parents, and peers can strengthen the effectiveness and sustainability of nutrition education programs. In conclusion, structured nutrition education significantly contributes to fostering healthier eating habits in young populations. These findings underscore the necessity for continued, multidisciplinary, and contextually relevant nutrition education to combat the rising prevalence of obesity and promote long-term well-being among school students]]>
