The Ministry of Agriculture, Food and Rural Affairs has conducted the Dietary Education Projects at Childcare Centers since 2015. This study provides preliminary data for early childhood dietary education programs, by evaluating the outcomes of the projects. This survey enrolled 212 participants whose children had participated in the projects, and 142 non-participants. Comparing the perception of importance towards each educational program of the projects, dietary education program gained significantly higher importance than other subjects included, and was significantly higher in the participants than in non-participants. In the preference for food group survey for children, vegetable and seaweed preferences were higher among participants than non-participants, indicating that participation in the dietary education projects contribute towards increase in preferences for vegetables and seaweed, which children generally dislike. No significant differences were observed in children’s dietary habits between participant and non-participant groups, thereby suggesting that the education projects were insufficient for inducing dietary habit changes. In order to accomplish effective improvement of dietary habits, the education projects need further improvements to achieve systematic and long-term plans.
