The environmental impact of food consumption depends on the type of foods consumed and the amount of food wasted. It follows that dietary change represents one means of directing food systems towards greater environmental sustainability. The difficulty, however, lies in developing ways of...

The effect of consumers’ compliance with nutritional recommendations is uncertain because of potentially complex substitutions. To lift this uncertainty, we adapt a model of consumer behaviour under rationing to the case of linear nutritional constraints. Dietary adjustments are thus derived...

The paper develops a framework combining a model of rational behaviour under dietary constraints, an epidemiological model of diet-related mortality, and a life-cycle-analysis model of environmental impact, which permits the ex-ante assessment of dietary recommendations in multiple...
