This work therefore aims to assess the environmental, economic and nutritional quality dimensions of the menus consumed across the Local Network of School Canteens in the municipality of Ames (Galicia, Spain). It additionally performs different scenarios to evaluate the effects on the environment-cost-nutritional quality trilemma of implementing two major dietary changes in these menus: introducing more organic products, and shifting toward a more plant-based consumption pattern. To this end, this study considers the following indicators: a) those obtained from an energy and carbon life cycle assessment of the school menus (cradle-to-grave approach), mainly the cumulative energy demand (CED) and the carbon footprint (CF), complemented by some energy efficiency indicators; b) the total cost (TC) of the menus, obtained from their life cycle cost assessment (cradle-to-fork approach); and c) the nutritional quality of the menus, calculated and assessed based on the nutrient rich diet index (NRD 9.3). The CED, CF, TC, and NRD 9.3 index of a daily meal at school canteens are, respectively, estimated at 18.87 MJ, 1.30 kg CO2-eq, EUR 4.65, and 278 per meal. The consumption of animal products and labor (for food preparation) are identified, respectively, as the main environmental impact and economic cost of the menus. The results of our research show how implementing changes in consumption habits toward a more vegetarian diet in school menus makes it possible to include organic products to generate the most positive effects in terms of the environment and nutrition without incurring in cost overruns. Our work discusses the main barriers to be overcome and the political actions that must be enforced to advance the procurement of more sustainable and healthy public food.
