The current western diet is filled with an excessive amount of processed foods from the industrial age. In this work, we address the Menu Planning Problem for an individual or a group, finding efficient solutions that are healthy and reliable while handling different objectives: minimizing cost and environmental impact and maximizing palatability. In order to obtain efficient solutions, we use different heuristic strategies to optimize the Wierzbicky achievement function of a model with nutritional, cultural, and economic constraints. There is an inherent trade-off between cost and environmental impact, highlighting the importance of considering multiple criteria when making menu planning decisions. Our method provides a valuable tool for menu planners, enabling them to explore the feasible region and find Pareto-efficient solutions that satisfy individual preferences and system constraints.
