Development and evaluation of play-based food and nutrition education materials for early childhood through sensory experiences: a pre-post observational study

This study developed experiential, PBNE materials aligned with the national standard child- and play-centered curriculum. The materials were effective in enhancing food awareness and promoting attempts at consumption. Future efforts should focus on developing additional experiential teaching tools that incorporate teacher feedback and on strengthening home-linked programs to support healthy seasonal food intake and positive dietary experiences in young children.
