Decreasing the environmental footprint of our diet – a modelling approach using Optimeal®

Calculations with a quadratic programming model (Optimeal®) can give insight in the ecological effects of the replacement of animal foods by plant-based foods in the diet. The Optimeal® model can recalculate a healthy alternative diet providing all nutrients needed and, in addition, calculate the environmental impact and consumer price of this diet. The results show that the general paradigm ‘eat a less animal and more plant-based diet’ is not a guarantee to reduce the environmental footprint. Nevertheless, reducing the carbon footprint is feasible by complying to ten eating rules based on these calculations.
