There is little agreement among governments, institutions, scientists and food activists as to how to best tackle the challenging issues of health and sustainability in the food sector. This essay discusses the potential of school meals as a platform to promote healthy and sustainable food behavior. School meal programs are of particular interest for improving public diet because they reach children at a population scale across socio-economic classes and for over a decade of their lives, and because food habits of children are more malleable than those of adults. Current research on the history and health implications of school meal programs is reviewed in a cross-national comparative framework, and arguments explored that speak for the need of a new developmental phase of school meals as an integrative learning platform for healthy and sustainable food behavior. Nutritional, social, practical, educational, economical, political, and cultural perspectives and challenges linked to the implementation of healthy and sustainable school meals are discussed. Finally, the need for long-term interventions and evaluations is highlighted and new research directions are proposed.

Nutrition-related diseases, such as some cancers, heart diseases, and obesity, belong to the most challenging health concerns of our time. Communicating intuitive and simple nutrition information by means of front-of-pack (FOP) nutrition profile signpost labeling is increasingly seen as an essential tool in efforts to combat unhealthy food choices and improve public health. Consequently, much attention in policy and research is given to nutrient profiling methods and the determination of optimal nutrition criteria. Although consumer research on nutrition signpost labeling is now gradually appearing in the literature, the value and meaning of these labeling systems for consumers have received less attention. In the current debate a concise overview is lacking of the consumer perspective, including relevant psychological phenomena, in relation to much debated controversies surrounding these labels and their further development, such as the most effective type of signpost labeling system and varying stakeholder interests. Therefore, this paper aims to critically review the literature in the consumer domain of FOP nutrition labeling in order to illustrate the strengths and weaknesses of this form of nutrition education from a consumer perspective.

The essence of nudging is to adapt the environment in which consumers make decisions to help them make better choices, without forcing certain outcomes upon them. To determine how consumers can effectively be guided to select healthier snacks, we examine the effect of manipulating the assortment structure and shelf layout of an impulse display including both healthy and unhealthy snacks near the checkout counter of a canteen.
