Culinary preparations, how to determine when they are part of a sustainable diet?

The adoption of sustainable forms of consumption and production is an imminent need due to the adverse consequences that current food systems have on health and the planet. Although studies show that people value a lesser effect of diet on the environment, they do not know how to evaluate its impact in this sense. This qualitative literature review investigated the existence of indicators or tools to assess the sustainability of culinary preparations as part of a sustainable diet. Definitions, approaches, and ways of measuring and evaluating sustainable diets and sustainable gastronomy at the global and national levels were included. The search for scientific articles was carried out in the Medline/PubMed, Scopus, Web of Science and SciELO databases using as keywords "sustainable diets", "sustainable diets", "ecogastronomy", "sustainability assessment", "out of home meals", "sustainable gastronomy", "sustainable diet", "sustainable healthy diets", "sustainability indicators", "sustainable indicators", "sustainability index", "sustainable diets index", "dietas sustentaveis". Every diet has an impact on the environment, however, factors such as its composition and forms of production determine the magnitude of this impact. A central issue revolves around the methodologies to measure, analyze and evaluate the different aspects that make up the sustainability of diets, and there is little evidence regarding tools to qualify culinary preparations according to their level of sustainability. Therefore, further research is required in this area in order to contribute to the adoption of healthy and sustainable diets the
