Worksites are a suitable platform for employees to engage in behavioral change towards a healthy lifestyle by the modification of the food environment. Grading canteen foods at worksites into categories of relative healthfulness is an important indicator in the planning of food environmental interventions. However, in the absence of mandatory front of pack (FOP) labelling in South Africa, categorizing packaged and cooked food at worksite canteens is challenging. A scoping review was conducted on FOP labelling schemes to inform the selection of a FOP labelling scheme best suited for canteen foods at worksites in South Africa. The results of the scoping study, tabulated into a narrative summary, showed that there are several well-developed approaches to classifying foods by relative healthfulness through nutrient profiling and different forms of expression. It is recommended that because worksite canteen food sales in South Africa include both packaged and cooked food, and that a general test of various labelling schemes should be conducted to determine if a directional change is made towards purchasing healthier foods. Grading foods using interpretational aides such as an adapted FOP nutrition label to the South African context into categories of relative healthfulness can be a practical tool to inform food environmental interventions at worksite canteens and beyond.
工作场所是员工通过改善食物环境来改变健康生活方式的合适平台。将工作场所食堂的食物分为相对健康程度的类别是规划食物环境干预的一个重要指标。然而，由于南非没有强制性的标签前置（FOP）标签，因此对工作场所食堂的包装食品和熟食进行分类具有挑战性。对 FOP 标签方案进行了范围审查，以为南非工作场所食堂的 FOP 标签方案选择提供信息，该方案最适合食堂食品。该范围研究的结果以叙述性摘要的形式列出，表明有几种通过营养成分分析和不同形式的表达来对相对健康程度进行分类的成熟方法。建议由于南非工作场所食堂的食品销售既包括包装食品又包括熟食，因此应该对各种标签方案进行一般性测试，以确定是否朝着购买更健康食品的方向做出了方向性改变。使用解释辅助工具（如适应南非国情的 FOP 营养标签）将食品分为相对健康程度的类别，可以作为在工作场所食堂及其他场所进行食物环境干预的实用工具。
