Achieving sustainable, healthy diets remains a global challenge to meet the sustainable development agenda by 2030. The purpose of this study is to derive optimal dietary recommendations for children that consider nutritional, environmental, and economic parameters of sustainability, using Lebanon as a case study. Data from the latest national food consumption survey conducted among Lebanese children were used. Optimized diets were derived using Optimeal, a software that produces similar patterns to the usual diet while considering nutrition constraints (energy, and macro/micronutrient needs), environmental footprints ((EFPs): water use, energy use, and greenhouse emissions), and cost. Three optimized diets were derived that meet the nutritional needs of children aged 4–8, 9–13, and 14–18 years, while considering EFPs and cost. Compared to the usual intake, optimized diets included higher intake of vegetables, legumes and dairy, and a decrease in saturated oils, processed meats, sugar, salty snacks, sweets, and sugar-sweetened beverages. Overall, the optimized diets decreased cost by 20% and reduced water use, energy use, and GHG emissions, by 20%, 11%, and 22%, respectively. The proposed models consider various constraints and provide sustainable solutions for decision makers within a country undergoing crises. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
