5. Strengths and limitations
Although this study presents new findings on promoting FNLIT in primary children, it also has some limitations. The most important of these limitations are the following. First, the inconsistency of some unhealthy food advertising on national media with the nature of the study curriculum, that the effect of unhealthy food advertisements on ongoing and sustained training, group discussions, and criticism of unhealthy food advertising in the national media counteracted the target group.Second, the lack of inter-sectoral cooperation between the Ministry of Health and the Ministry of Education to provide children with proper education on healthy nutrition and promote their food and nutrition literacy has exacerbated the dilemma and should be addressed at the national level by health policymakers. Third, children usually prefer unhealthy foods to natural and healthy ones because of their flavors/taste. Many children know healthy foods and may have access to them but still choose to eat unhealthy ones. In order to change this, the issue must be addressed in a multifaceted and inclusive way, and all the different sections involved should take part in resolving it. Finally, the generalizability of the results was limited to Iranian primary school students in the Baneh region in Kurdistan.
