Understanding the complexity of the elements that constitute organizational food environments and their operating dynamics is essential to improving their healthiness. This study developed a conceptual model of organizational food environments. For this purpose, a comprehensive literature review was conducted, a first version of the conceptual model was prepared, a panel of experts was consulted, the model was improved, a second panel of experts was consulted, and the model was finalized. The model consists of four components (the institutional level, internal level of eating spaces, surroundings, and the decisional level) and 10 dimensions related to the institutional level and internal level of eating spaces (the availability, accessibility, affordability, quality, food and nutrition information, and promotion of foods, beverages, and culinary preparations and the availability, acceptability, convenience, ambience, and infrastructure of the eating space), as expressed in a graphical scheme. The conceptual model presented here offers innovative elements which contribute to understanding of the organizational food environment. It can guide the development of both assessment studies of food environments and interventions for their improvement.
