Healthy, environmentally friendly and socially responsible : how an online tool helps to cook more sustainably

Every diet has an impact on an individual's health status, the environment as well as on social aspects. In particular, ecological and social concerns are usually only vaguely assessed in the daily routines of out-of-home catering and a systematic sustainability assessment of meals is usually not carried out. Since May 2018, the menu calculator presented in this paper has been supporting stakeholders in various catering establishments with their sustainability assessment. The tool was developed within the NAHGAST project (www.nahgast.de) in cooperation with five practice partners and tested and validated by a total of 120 recipes. This article provides an overview of selected recipes' sustainability assessments (meals with fish and meat as well as vegetarian and vegan meals) and highlights the effects on the ecological, health and social dimensions
