The aim of this study was to develop a novel dietary education program, which both junior high school students and their parents could relate to, and to evaluate its effectiveness using objective indices. The program focused on the theme of box lunches requiring filioparental involvement. It was effective in improving the nutritional balance of the box lunches by increasing vegetables. However, in the follow-up survey seven months after the end of the intervention, the vegetable intake during school lunch was maintained ; however, the nutritional balance of box lunch had reverted to its former state. This study suggests that dietary education programs should be evaluated objectively and conducted regularly to maintain their effect.
