The purpose of this study is the systematization of the contents analysis to develop school dietary education based on the government-published textbooks for elementary school students. The components of the content are divided into several categories that include a general perspective of the pages, illustrations, table of contents, introductory remarks, summary evaluation, and etc. This study carried out as basic fundamental research to propose a theoretical framework for the elementary school dietary education. We examined and analyzed the nature and characteristics, the educational goals, and the structural framework of the contents of the textbooks. We have developed a systematic structure with 4 large content elements for dietary education as foods & cooking, nutrition & health, dietary environment & consumption, and food culture & industry. This analysis will definitely play an important role in establishing a standard framework and the curriculum contents for school dietary education in elementary school.
