This randomised controlled trial investigated the effect of a Mediterranean diet (MD)-based nutritional intervention on children and adolescents with coeliac disease. The intervention group received standard therapeutic education alongside MD-based nutritional education, psychological support, and cooking workshops, while the control group received only standard education. After 90 days, the intervention group showed significantly higher adherence to both the Mediterranean and gluten-free diets, improved lipid quality, and increased fibre and calcium intake. They also experienced reduced sedentary time and better coeliac disease-specific quality of life scores. The study concludes that this integrated educational approach is a promising strategy for managing coeliac disease in young people.
This research is important because it offers a comprehensive strategy to improve the nutritional status and quality of life for children and adolescents living with coeliac disease. By integrating dietary education with psychological and practical support, it addresses the challenges of maintaining a strict, yet nutritionally adequate, gluten-free diet.
This research presents an applied, tested nutritional and educational programme for paediatric coeliac disease management. It could be developed into a structured support programme or educational toolkit for healthcare providers, dietitians, and patient organisations. The findings suggest a clear pathway for improving patient outcomes, potentially leading to improved health services and resources for families managing coeliac disease.

Introduction Although strict adherence to gluten-free diet (GFD) is essential for celiac disease (CeD) management, it does not necessarily ensure optimal or nutritionally adequate diet and lifestyle. Objective To assess the impact of combining Mediterranean diet (MD)–based nutritional education, and psychological and culinary workshops on adherence to GFD, dietary quality, physical activity (PA), and quality of life (QoL) in children and adolescents with CeD. Methods A randomized controlled trial was conducted in 59 celiac children and adolescents (aged 5–18 years), allocated into two groups. The intervention group (IG, n = 35) received standard therapeutic education plus MD–based nutritional education, psychological support sessions, and cooking workshops. The control group (CG, n = 24) received only standard therapeutic education. Anthropometric measurements, biochemical parameters, MD (KIDMED index) and GFD (CDAT) adherence, PA, CeD-specific QoL (CDDUX), health-related (HR) QoL (KIDSCREEN-10), and nutritional intakes were assessed at baseline and at day 90. A linear mixed- model was used to assess the effect of group, time, and their interaction on MD adherence. A multivariate linear regression analysis was performed to identify independent predictors of change in MD adherence (ΔMD). Results At day 90, IG exhibited higher MD adherence ( p < 0.001), better GFD adherence ( p = 0.002), and improved lipid quality ( p < 0.05), compared with CG. Moreover, increased intakes of fiber ( p = 0.010) and calcium ( p < 0.001) were noted. Reduced sedentary time ( p = 0.005), and higher CDDUX “GFD domain” scores ( p = 0.05) were observed. At day 90 in IG, significant improvements were observed for KIDMED index GFD adherence, as well as fiber, protein and calcium intakes ( p < 0.001). Additionally, CDDUX ( p < 0.001), and KIDSCREEN-10 ( p < 0.001) scores were improved compared with baseline. The linear mixed model revealed a significant group × time interaction (β = −4.42, p < 0.001), indicating that the change in MD adherence over time differed significantly between groups. In multivariate analysis, belonging to the IG (β = 4.52, p < 0.001) and having difficulty in gluten-free bread preparation (β = 1.65, p = 0.008) were independently associated with improvement in ΔMD. Conclusion Integrating MD–based nutritional education into reinforced therapeutic education represents a promising strategy for the long-term management of CeD in children and adolescents.
