To verify the effectiveness of dietary education activities that incorporate dishes from picture books into school lunches and to understand the actual situation of picture books and school-lunch contents, this study surveyed staff involved in nursery school lunches. The questionnaire results demonstrated that all but one nursery school implemented planned dietary education activities: approximately 90% aimed for “children who talk about food” and “children who want to eat and like more things.” Top foods served among the 29 school lunches were broad beans (18), pancakes (7), and homemade bread (5). Effects of dietary education activities included: “Interest in food and school lunches expanded,” “Children who did not like the food were able to eat it,” and “School lunches became a topic of conversation at home.” There was a significant correlation between the number of dietary education goals selected and the number of chosen dietary education effects. The goals and effects also aligned, suggesting that dietary education activities that incorporate dishes from picture books into school lunches effectively achieve the desired results.
