CONGRESO Designing healthy, climate friendly and affordable school lunches


It is well-known that the feeding of students is related to their health and well-being, contributing to a reduction in the risk of chronic dis-eases in adulthood. However, students¿ parents also take the cost of school lunches into account. In addition, we should not forget that the food sector contributes to 15-30% of the total greenhouse gas emissions and, as such, food choices can have a notable influence on cli-mate change. Although these three aspects, health, environment and cost, need to be borne in mind in order to build sustainable lunches, they are not necessarily convergent. In this context, this study aims to develop a model with which building a sustainable school diet while taking nutritional, environmental and economic aspects into account. Interval goal programming can be very useful as a means of addressing this problem. By establishing two goals, an economic one and a carbon footprint (CFP) one, positive deviations can be mini-mized while keeping the recommended daily intake (RDI) fractions (macronutrients and micronutrients) and energy in the expected range.
