Defaults harmonize our food choices – a systematic data review of default effects across socio-demographic groups
Food policy often struggles to reach diverse population groups, and well-intentioned interventions can sometimes exacerbate inequalities along socio-demographic groups. This systematic data review examines whether default nudges in food choices have consistent effects across different socio-demographic groups, or whether their impact varies depending on factors such as education level, age, and gender. After selecting eligible studies, authors fr…
Examining public support for comprehensive policy packages to tackle unhealthy food environments
Objective: This study examines public support – and its drivers – for comprehensive policy packages (i.e. bundles of coherent policy measures introduced together) aimed at improving food environments. Design: Participants completed an online survey with a choice-based conjoint experiment, where they evaluated pairs of policy packages comprising up to seven distinct food environment measures. After choosing a preferred package or opting for a sing…
A choice architect’s guide to the (autonomous) galaxy: A systematic scoping review of nudge intrusiveness in food choices
In seeking to uphold consumer autonomy in the design and implementation of nudge interventions, choice architects must concern themselves with preserving both the availability of options made to consumers (freedom of choice), and the capacity of consumers to deliberate and choose (agency) Several studies aim to examine the extent to which nudges truly uphold autonomy; however, most examine self-reported perceived intrusiveness on autonomy, rather…
Evidence on the Effectiveness-Acceptance Trade-Off Between Forced Active Choice and Default Nudging: A Field Study to Reduce Meat Consumption in Cafeterias
Overconsumption of meat remains common in Western diets. In a cafeteria setting, we assessed the impact of two interventions on reducing meat consumption: forced active choice (explicitly choosing meat portion size) and default nudge (offering a reduced meat portion with an opt-out option). Our field study, involving 5,966 food choices and feedback from 125 cafeteria users, revealed both interventions were effective and perceived as ethical. Acro…
Options to design more ethical and still successful default nudges: A review and recommendations
On the one hand, default nudges are proven to strongly influence behavior. On the other hand, a number of consumer autonomy and welfare concerns have been raised that hinder public policy applications. Both nudge success and ethical concerns depend heavily on the design of defaults. We identify six taxonomic characteristics that matter to the ethical and the nudge success dimension. We review the default nudge literature ( N = 61) and review ethi…
Public acceptance of default nudges to promote healthy and sustainable food choices
Mitigating the costliness of opting out and improving nudge transparency emerge as key opportunities for choice architects to improve public acceptance, and thereby potentially identify 'sweet spots' in designing default nudges that are both effective and acceptable. The protection of individual freedom of choice and effectiveness are key aspects for choice architects to communicate to increase acceptance

Consumer demand for novel fruit and vegetable products with extended shelf lives in East Africa: A multinational multi-product analysis
Objective: To evaluate the potential of products made out of underutilised fruits and vegetables for closing seasonal nutritional gaps among rural and urban consumers in East Africa. Design: The multinational analysis combines sensory testing and experimental auctions to assess consumers’ perceptions and willingness to pay (WTP) for 6 different fruit and vegetable products. Setting: Open markets in rural and urban areas in Kenya, Tanzania and Uga…
More room for legume – Consumer acceptance of meat substitution with classic, processed and meat-resembling legume products
Staatliche Eingriffe in die Lebensmittelwahl: Welche klimapolitischen Instrumente unterstützt die Bevölkerung
Staatliche Eingriffe in den Lebensmittelkonsum der Deutschen sind im europäischen Vergleich eher selten. Politiker(innen) empfinden wohl Lenkungssteuern- oder Werbeverbote als unpopulär. Konkrete Maßnahmen zum Klimaschutz, etwa eine Klimasteuer auf importierte Flugwaren, stoßen jedoch auf breite Zustimmung und könnten durchaus zu Klimazielen beitragen.In view of climate change, policy approaches addressing the consumption side of nutrition are be…
