“…A fourth narrative review demonstrated that although nudging interventions focusing on one specific aspect (e.g. availability, accessibility, visibility) were moderately effective, combined strategies including multiple factors at once were the most effective in achieving healthier food choices (Wilson, Buckley, Buckley, & Bogomolova, 2016). All reviews stress that the quality of studies included was suboptimal, and in some cases even weak, and that more systematic, experimental studies are needed into the effectiveness of nudging strategies.…”

Objective: To discuss healthy diet from a psychological perspective by considering definitions of healthy diet in terms of consumer understanding; the health effects of specific dietary elements in terms of overweight and (chronic) illness; the prevalence of healthy diet; the psychological and environmental determinants of healthy diet; and the psychological interventions that have been designed to promote healthy diet. Design: A systematic review of the psychological literature on healthy diet. Results: Our findings suggest that consumers have a relatively poor understanding of a healthy diet. The literature also demonstrates that there is poor evidence on the health protective effects of single foods or nutrients. We further show that low SES is the single consistent risk factor for not adhering to a healthy diet. Our review of the literature on determinants demonstrates that intentions, habits, self-regulatory skills, and the social and physical environment are the most important determinants of a healthy diet, which are in turn amenable to change by intervention strategies with varying levels of effectiveness. Educational interventions generally show a limited effect on practising a healthy diet whereas interventions targeting habitual behaviour and/or the physical environment seem more promising. Conclusions: In view of the large number of people who are concerned about their diets and make attempts to change their dietary patterns, we conclude that it is crucial to gain a better understanding of both the automatic and environmental influences that are responsible for people not acting upon their good intentions for diet change.

“…Wilson et al 18 concluded from their review of 13 articles that combined 'salience' and 'priming' nudges show a consistent positive influence on healthier food and beverage choice. Bucher et al 19 found a positive effect of positional changes of food placements on food choice in sixteen out of 18 studies, but like Wilson et al 18 also mentioned a need for higher quality studies in the field. In line with these reviews, Hollands et al 6 underlined that there is not an absence of evidence, but rather a lack of definitional and conceptual clarity concerning the applications of choice architecture interventions and nudging and of high-quality systematic reviews in this area.…”

BACKGROUND: Nudging refers to interventions that organize the choice architecture in order to alter people's behaviour in a predictable way without forbidding any options or significantly changing their economic incentives. As a strategy to encourage healthy behaviour, nudging can serve as a complement to health education. However, the empirical evidence regarding the effectiveness of nudging as a way to influence food choice remains contradictory. To address this issue, a systematic review and meta-analysis was conducted to test the effects of nudging to encourage people to select more fruit and vegetables. METHODS: A systematic literature search was performed on PubMed, Medline, PsycInfo, Cochrane library, Scopus and Google Scholar. After quality assessment, 20 articles (23 studies) were retained for narrative synthesis. Twelve articles (14 studies) contained enough information to calculate effect-sizes for meta-analysis using Comprehensive Meta-analysis software. RESULTS: The meta...

“…Recently a systematic review by Wilson et al (2016) demonstrated, when choice options are re-arranged, food choice outcomes can be improved. This was also shown in studies investigating middle choice preferences for food (Keller et al, 2015), however without controlling for selfregulatory resources, as this may be key for a successful implementation of this particular nudge.…”
