Nutrition labelling is a strategy to promote healthy eating and combat non-communicable diseases (NCDs). The present study aimed to provide an analysis of the nutrition labelling policy and its opportunities to improve in Iran. Data were collected by 1) reviewing relevant documents and 2) semi-structured interviews with stakeholders through purposive and snowball sampling, continued until data saturation was achieved. A deductive content analysis was used by applying the policy triangulation framework and the Kingdon multiple stream theory. MAXQDA software was used to manage data analysis. Iran, is the first country in the Eastern Mediterranean region which has accomplished to implement nutrition traffic light labelling. The main contextual factors that affected nutrition labelling policy to become a national included health, political commitment, and international factors. Poor involvement of media for public awareness of nutrition traffic labeling, the inconsistency of nutrition traffic light color ranking using food standard guidelines, lack of consistency between nutrition traffic light colors and the healthy/unhealthy nature of some food products and the absence of a comprehensive evaluation plan were among the policy challenges identified. Strengthening the governance for a healthy food environment is recommended to improve the program. Also, establishing national portion sizes for food labelling, initiating public awareness campaigns, evaluation of the policy effect and public perception of the labels and their application are recommended.
