An important way to understand the methods used in the nutritional literacy of different groups is the study of existing scientific productions. Thus, the objective of this study is to carry out a scope review on educational nutritional literacy interventions and to classify them according to the economic situation of the country of origin. The review was built based on the methodology proposed by The Joanna Briggs Institute (2015), written according to the PRISMA-SCR guidelines (PRISMA extension for scope reviews) (TRICCO et al., 2018) and the studies included according to the PCC strategy (population, concept and context of the study). The inclusion criteria were to include adults of both sexes, healthy or with chronic diseases. The databases used were PubMed, MEDLINE (OVID), SCIELO, LILACS, BVS, Web of Science, Scopus, Science Direct and Google Scholar. We use the World Bank (2020) for the economic classification of countries. In the research, 1,864 articles were found and, after reading all of them, 17, that met the inclusion criteria, were selected. They were developed in 5 countries: Australia, 4 (23.53%), United States, 8 (47.06%), Canada, 3 (17.65%), Switzerland, 1 (5.88%) and Greece, 1 (5.88%). All countries were classified as having high annual income per capita ($ 12,536 or more) and were distributed on only three continents: North America, 11 (64.71%), Oceania, 4 (23.53%) and Europe, 2 (11.76%). The interventions occurred through videos (5.88%), applications (11.76%), workshops (11.76%), campaigns (5.88%), audios (5.88%), serious games (5, 88%), classes (23.53%) or using two or more forms of intervention in the same study (23.53%). It was possible to observe that there is a concentration of studies in rich contries. The scarcity of interventions in low- and middle-income countries may be due to the lack of resources, as they are still in the epidemiological diagnosis and survey phase, or even because they are not aware of the importance of nutritional literacy. There is a need for further studies in low and middle income countries to better understand the functioning of nutritional literacy skills in different populations.
