Cooking-based nutrition education (CBNE), which promotes acceptance through direct experience, may support the development of healthy eating habits. This study aimed to develop and implement a standardized CBNE program for school-aged children in Seoul, South Korea, and to evaluate its effectiveness by assessing changes in raw vegetable intake. Raw vegetable intake is an early indicator of the effectiveness of nutrition education on diverse topics in promoting healthy eating habits.</p><p><strong>Methods: </strong>A single-group pre-post study was conducted with 37 children aged 6-11 years who participated in a 2-day CBNE program in October 2023.
