This study aimed to measure the reported use of food labeling by grocery shoppers in Semnan city, Iran. In this descriptive cross-sectional study, 339 people were selected by a cluster random sampling plan from a chain store in Semnan city. For each of the participants, a demographic questionnaire and performance about food and labels were completed. Data were analyzed by SPSS. The study samples consisted of 139 (41%) males and 200 (59%) females. The average age of the participants was about 32 years. About 86.4% of respondents based on observation interviewing looked at information on the package before making a selection. However, in self-reported behavior, 98.5% of consumers said that looked at food labeling. Our study results propose that self-reported behavior when compared to measures based on observation interviewing on the actual purchase, lead to overreporting. Therefore, research on consumer attention to food labeling is an immediate need. https://jfsh.tums.ac.ir/index.php/jfsh/article/view/149 https://jfsh.tums.ac.ir/index.php/jfsh/article/download/149/90
