ABSTRACT Introduction: food is a human right and a basic need for their subsistence and development. enough food is produced worldwide to supply all inhabitants and satisfy their caloric and nutritional needs. But the mere fact of producing them does not ensure access to safe and nutritious food for all. Therefore, the correct measurement of nutritional food insecurity is essential for a better understanding of this phenomenon, allowing better communication between society, decision-makers and the political agenda. Objectives: analyze the strengths and limitations of the methodologies used to measure nutritional food security in the Argentine Republic between 1984 and 2017. Materials and methods: a systematic review of articles published in five electronic databases was carried out: Scopus, SciELO, PubMed, BVS and Redalyc. The categories analyzed were the nutritional food security measurement methodologies (when people enjoy food security in addition to a healthy environment, as well as adequate health, education and care), with their type of technique, level, duration and dimension evaluated, limitations and strengths. The search terms used were food insecurity, food security, hunger, food sovereignty, food policy, food availability, nutritional programs, nutritional policies and food assistance. Results: after the search, 22 articles were selected for analysis. Conclusions: all the methodologies analyzed take partial aspects. A methodology has not yet been developed that reflects the multisectoral (food, agricultural, governmental, economic, social, etc.) and multidimensional (access, availability, use and stability) nature of the concept of nutritional food security. Having an adequate measurement of nutritional food security is essential to assess the state of nutritional food insecurity in the Argentine Republic, the government policies that are developed under this concept and verify its impact on the health and nutrition of the Argentine population. Key words: food security; food insecurity; hunger; nutrition policy; Argentina.
