Planetary Health Diet for Childhood Obesity Prevention: Integrating Nutritional Health with Environmental Stewardship

Background: Childhood obesity is a critical public health challenge with a rising prevalence worldwide, contributing to numerous health risks and long-term societal burdens. Concurrently, climate change and environmental degradation demand sustainable approaches to dietary patterns. The Planetary Health Diet (PHD), initially designed for adults, emphasizes plant-based foods and sustainable practices. Objectives: This review explores the suitability of the PHD for addressing childhood obesity by assessing its nutritional adequacy and proposing necessary adaptations for pediatric populations. Methods: A narrative review methodology was employed, examining data from global and regional nutritional guidelines and evaluating the PHD’s bromatological composition against age-specific requirements. Results: The findings indicate that while the PHD aligns with environmental goals, it may not fully meet the energy and specific nutrient needs of children and adolescents without modifications. Key challenges include ensuring adequate intake of bioavailable protein, iron, calcium, vitamin B12, and vitamin D. Strategies such as incorporating fortified foods, optimizing food pairings, and gradual adaptation to high-fiber diets are critical for successful implementation. This review also highlights the importance of cultural adaptability, family involvement, and regional food systems in promoting adherence. Tailored interventions, such as school meal programs and educational initiatives, can bridge gaps in nutrition while fostering sustainable dietary behaviors. Conclusions: Adapting the PHD for pediatric needs presents an opportunity to integrate nutritional health with environmental stewardship, contributing to obesity prevention and a sustainable future. Further research is required to validate these adaptations and develop comprehensive frameworks for global implementation.
