Preschool children's interest in popular culture is linked to many determinants of obesity development including branded energy-dense foods and sedentary play using digital technologies. In addition, highly packaged foods and throwaway toys reinforce unsustainable environmental habits encouraged by immersive marketing systems. Interrupting the effects of these systems demands multiple and diverse solutions. Our solution engages early childhood educators in obesity prevention by doing what they do best--pedagogy, curricula and care. Assisting young children to interact with their interests and developing habits like Healthy eating, Active play and environmentally Sustainable practices (HAS) is unique methodology. We believe that building the capacity of educators to co-create HAS curricula using children's interests has the potential to develop life-long well-being and sustainability habits. HAS curricula aid in young children's development of agentic decision-making abilities through the transformation of everyday concepts into higher-order mature concepts.
