This article describes the process evaluation of two environmental programs and a educational nutrition program, implemented at supermarkets and worksite cafeterias. Studies conducted earlier, indicated that the programs had no effect on consumers’ eating behavior. Consequently, the more specific purpose of the present study was to identify explanations for the ineffectiveness of the programs and to formulate recommendations for future programs. Materials and Methods The environmental programs included labeling of healthy products and increasing the range of healthy foods on offer. The education program consisted of several elements, such as brochures and a self-help guide. Semi-structured interviews were conducted with twenty-one managers of supermarkets and worksite cafeterias where the programs were implemented. Results Although materials were not always entirely compatible with the different supermarkets and worksite cafeterias, the degree of implementation was satisfactory. According to the managers, the programs were not striking enough, the labeling would have been more effective if it had discriminated between different brands of a product, and the number of new products was too small compared to the total range of foods on offer. Discussion The results can be used to help design and check future intervention programs for use at supermarkets or worksite cafeterias. Recommendations for future programs and research are given.
