Abstract
BACKGROUND Development of methods to accurately measure dietary intake in free-living situations-restaurants or otherwise-is critically needed to understand overall dietary patterns. OBJECTIVE This study aimed to develop and test reliability and validity of digital images (DI) for measuring children's dietary intake in quick-service restaurants (QSRs), validating against weighed plate waste (PW) and bomb calorimetry (BC). DESIGN In 2016, cross-sectional data were collected at two time points within a randomized controlled trial assessing children's leftovers in QSRs from parents of 4- to 12-year-old children. PARTICIPANTS/SETTING Parents (n = 640; mean age = 35.9 y; 70.8% female) consented and agreed to provide their child's PW for digital imaging, across 11 QSRs in Massachusetts in areas with low socioeconomic status and ethnically diverse populations. OUTCOME MEASURES Outcome measures were interrater reliability for DIs, correspondence between methods for energy consumed and left over, and correspondence between methods across varying quantities of PW. ANALYSES PERFORMED Intraclass correlations, percent agreement, Spearman correlations, Wilcoxon signed rank tests, and Bland-Altman plots were used. RESULTS Interrater reliability ratings for DIs had substantial intraclass correlations (ICC = 0.94) but not acceptable exact percent agreement (80.2%); DI and PW energy consumed were significantly correlated (r = 0.96, P < 0.001); DI slightly underestimated energy consumed compared with PW (Mdiff = -1.61 kcals, P < 0.001). Bland-Altman plots showed high DI-PW correspondence across various energy amounts and revealed few outliers. Energy left over by BC was highly correlated with DI (r = 0.87, P < 0.001) and PW (r = 0.90, P < 0.001); and mean differences were not significantly different from DI (Mdiff = 9.77 kcal, P = 0.06) or PW (Mdiff = -2.84 kcal, P = 0.20). CONCLUSIONS Correspondence was high between PW and DI assessments of energy consumed, and high with BC energy left over. Results demonstrate reliability and practical validity of digital images for assessing child meal consumption in QSR settings.

Caso G, Vecchio R. Nudging low-medium income mothers towards healthy child options in an online restaurant scenario. Appetite 2023; 180:106360. [PMID: 36343869 DOI: 10.1016/j.appet.2022.106360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/18/2022] [Accepted: 10/27/2022] [Indexed: 11/06/2022]
Abstract
Helping mothers make the healthiest choices for their children when eating out can contribute to preventing the prevalence of childhood overweight and obesity, particularly in economically disadvantaged classes. Herein, we tested whether two different nudges (a default option and a social norm prompt) could guide low- and middle-income mothers towards healthier children's menu choices in a fictive restaurant setting and investigated the drivers of healthy child menu selection. A cross-sectional online survey was performed among 809 Italian mothers with children aged between 3 and 12 years, and a between-subjects design (control, nudge 1, and nudge 2) was applied. The findings revealed that both nudges had no significant effect on the number of healthy menu selections compared with the healthy choices made in the control condition. Furthermore, considering the entire sample, the results show that certain characteristics of a mother (e.g., authoritative parenting style) and child (younger age) duo increase the likelihood of the former selecting a healthy children's menu. Similarly, a positive correlation between the likelihood of choosing a healthy children's menu and the mother's involvement in the child's nutrition (meal preparation and weekly diet) was observed.

Abstract
OBJECTIVE The goal of this study was to examine the potential of an optimal-defaults intervention to promote grocery purchases corresponding to a diet for diabetes. METHODS In total, 65 adults diagnosed with or at increased risk for type 2 diabetes who grocery shopped at one of two study stores were randomized to one of three groups: Defaults, Online, or Control. All groups received diabetes-friendly recipes. In addition, the Online group was asked to grocery shop online during a 3-week intervention, and the Defaults group was asked to shop online, with their online grocery carts prefilled with food items needed to prepare provided recipes. Participants provided weekly grocery receipt data at baseline, at each week of the 3-week intervention, and at post-intervention. RESULTS Overall, the Defaults group had grocery purchases of a significantly greater nutritional quality versus other groups (F = 16.3, p < 0.001). Between-group comparisons of least-squares means showed consistent effects of the Defaults intervention while intervention components were in place, with a similar pattern for energy and carbohydrate content of grocery purchases. CONCLUSIONS These results build upon emerging evidence that optimal defaults can promote healthier grocery purchases. Continued examination of this approach could promote healthy food acquisition in accordance with individual dietary preferences and needs.

The impact of the consumer and neighbourhood food environment on dietary intake and obesity-related outcomes: A systematic review of causal impact studies. Soc Sci Med 2022; 299:114879. [PMID: 35290815 PMCID: PMC8987734 DOI: 10.1016/j.socscimed.2022.114879] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 02/19/2022] [Accepted: 03/04/2022] [Indexed: 12/16/2022]
Abstract
BACKGROUND The food environment has been found to impact population dietary behaviour. Our study aimed to systematically review the impact of different elements of the food environment on dietary intake and obesity. METHODS We searched MEDLINE, Embase, PsychInfo, EconLit databases to identify literature that assessed the relationship between the built food environments (intervention) and dietary intake and obesity (outcomes), published between database inception to March 26, 2020. All human studies were eligible except for those on clinical sub-groups. Only studies with causal inference methods were assessed. Studies focusing on the food environment inside homes, workplaces and schools were excluded. A risk of bias assessment was conducted using the CASP appraisal checklist. Findings were summarized using a narrative synthesis approach. FINDINGS 58 papers were included, 55 of which were conducted in high-income countries. 70% of papers focused on the consumer food environments and found that in-kind/financial incentives, healthy food saliency, and health primes, but not calorie menu labelling significantly improved dietary quality of children and adults, while BMI results were null. 30% of the papers focused on the neighbourhood food environments and found that the number of and distance to unhealthy food outlets increased the likelihood of fast-food consumption and higher BMI for children of any SES; among adults only selected groups were impacted - females, black, and Hispanics living in low and medium density areas. The availability and distance to healthy food outlets significantly improved children's dietary intake and BMI but null results were found for adults. INTERPRETATION Evidence suggests certain elements of the consumer and neighbourhood food environments could improve populations dietary intake, while effect on BMI was observed among children and selected adult populations. Underprivileged groups are most likely to experience and impact on BMI. Future research should investigate whether findings translate in other countries.

Abstract
Physical activity (PA) benefits health, and intensive environmental modifications can increase children’s PA. Research has not yet addressed if subtle environmental cues, such as posters depicting PA, increase child PA. In the current study, it was hypothesized that children exposed to active posters (vs. nature posters) would spend a larger proportion of free play time engaging with active toys (relative to sedentary toys). Participants were randomly assigned to one of two conditions in which posters on a laboratory wall depicted 1. People being active, or 2. Nature scenes. Children aged 5–10 years (N = 175) could play with up to eight toys (four active, four sedentary) while parents completed study-related surveys. The proportion of playtime that was active was compared between groups. Poster type did not have a significant effect on proportion of active playtime. Previous environmental interventions that increase children’s PA have done so through enhancing access to active opportunities, rather than via signage. It is possible that poster interventions such as this may not influence children’s PA, or perhaps other types of cues would have been more effective. Future research should investigate subtle environmental cues that match both the target audience and the accessible PA options (e.g., posters depicting children playing with available active toys) and explore other low-investment environmental modifications to boost children’s PA.

BMC Public Health 2022; 22:78.

Abstract
Background Restaurants are ideal settings for implementing food interventions targeted at children. Studies with adults suggest that changes to the physical menu can lead to healthier food choices; online studies with parents indicate that specific menu designs facilitate healthier choices. However, it is unknown whether applying well-established nudging and boosting methods to children’s menus also increases their choice of healthier meals in a real-world restaurant setting. Methods The effects of two versions of a restaurant menu on the frequency of choosing a healthy meal (newly created, healthy target dish) were tested in a blinded quasi-randomized controlled trial. The menu in the control condition contained all dishes (including the healthy target dish) in a standardized format. The intervention menu included nudging (e.g. comic character, fun attractive name for the dish) and boosting elements (e.g. information on low calorie density) next to the healthy target dish. Over five months, the control and intervention menus were switched every two weeks and records were made of how often the healthy target dish was ordered. Results In total, 607 orders were made from the children’s restaurant menu (57% from the intervention menu). During the intervention phase, 4.2% of all ordered dishes from the children’s menu were the healthy target dish, during the control phase, 4.4% of orders were for the target dish (p=.896). Conclusions Contrary to our hypothesis, a modified children’s menu did not lead to a significant increase in the number of orders for a healthy dish compared with a neutral control menu. Importantly, given that parents and children often choose the child’s dish together, particularly boosting methods that focus on social processes and joint decision making could be promising to increase children’s frequency of healthy food choices in restaurants.

Abstract
Restaurants are regular eating environments for many families. Children's consumption of restaurant foods has been linked with poorer diet quality, prompting emerging research examining strategies to encourage healthier eating among children in restaurants. Although taste is a primary determinant of restaurant meal choices, there is a lack of research considering children's perspectives on the taste of different healthier kids' meal options. The current study sought to examine, via objective taste testing, children's liking of and preference for healthier kids' meal options at a quick-service restaurant (QSR) and to describe bundled kids' meals with evidence of both taste acceptability and consistency with nutrition guidelines. Thirty-seven 4-to-8-year-old children completed taste tests of ten healthier main and side dish options. Liking and preference were assessed using standard methods after children tasted each food. Children also reported their ideal kids' meal. Results show the majority of children liked and preferred three main (turkey sandwich, chicken strips, peanut butter/banana sandwich) and side dishes (yogurt, applesauce, broccoli), with rank order differing slightly by age group. Accepted foods were combined into 11 bundles meeting nutritional criteria. Results highlight healthier kids' meals with evidence of appeal among children in a QSR. Findings can inform future research and may increase the success of healthy eating interventions in these settings.

Abstract
The global prevalence of children with overweight and obesity continues to rise. Obesity in childhood has dire long-term consequences on health, social and economic outcomes. Promising interventions using behavioural insights to address obesity in childhood have emerged. This systematic review examines the effectiveness and health equity implications of interventions using behavioural insights to improve children's diet-related outcomes. The search strategy included searches on six electronic databases, reference lists of previous systematic reviews and backward searching of all included studies. One-hundred and eight papers describing 137 interventions were included. Interventions using behavioural insights were effective at modifying children's diet-related outcomes in 74% of all included interventions. The most promising approaches involved using incentives, changing defaults and modifying the physical environment. Information provision alone was the least effective approach. Health equity implications were rarely analysed or discussed. There was limited evidence of the sustainability of interventions-both in relation to their overall effectiveness and cost-effectiveness. The limited evidence on health equity, long-term effectiveness and the cost-effectiveness of these interventions limit what can be inferred for policymakers. This review synthesises the use of behavioural insights to improve children's diet-related outcomes, which can be used to inform future interventions.

Abstract
This study evaluated orders of adult menu items designated as healthier at the Silver Diner, a regional full-service restaurant chain serving over 4 million customers annually. This restaurant implemented a healthier children’s menu in April 2012. Orders of adult menu items were abstracted from before (September 2011–March 2012; PRE; n = 1,801,647) and after (September 2012–March 2013; POST; n = 1,793,582) the healthier children’s menu was introduced. Entrées, appetizers, and sides listed as healthier options on the menu were coded as healthier. PRE to POST changes in the percentage of orders of healthier items, soda, and dessert were evaluated using McNemar tests of paired proportions. Orders of healthier entrées, appetizers, and sides on the adult menu increased PRE to POST (8.9% to 10.4%, 25.5% to 27.5%, and 7.3% to 9.3%, respectively), and soda and dessert orders decreased (23.2% to 21.7% and 29.0% to 28.3%, respectively). All shifts were statistically significant (p < 0.0001). Our findings demonstrate improvements in orders of healthier adult menu options during the same time frame as a healthy children’s menu change. Future research can help elucidate mechanisms to inform future health promotion efforts in restaurants in ways that have the potential to impact both adults and children.

Abstract
OBJECTIVE To examine the feasibility of taste testing and point-of-purchase prompting to promote healthier food choices at a food truck event. DESIGN A pre-/post-study was conducted where food trucks provided samples of healthy food items to patrons and implemented point-of-purchase prompting (promotional signage; verbal cues). Implementation fidelity, acceptability and initial effectiveness were assessed via observation, patron surveys and sales data. A linear mixed model with a random effect for subject (food truck) and fixed effect for time point (baseline, intervention and post-intervention) was used to assess changes in relative sales of promoted healthy items as a percentage of food items sold. SETTING Weekly food truck event in Buffalo, New York. PARTICIPANTS Seven food trucks; 179 patrons. RESULTS Implementation fidelity data illustrated that all food trucks complied with manualised procedures. Approximately one-third of surveyed patrons accepted a healthy sample, with the majority rating the sample positively. There was no main effect of time when examining changes in relative sales of promoted healthy items across all periods (P = 0·32); however, effect sizes representing changes between individual time points are consistent with an increase from baseline to intervention (d = 0·51), which was maintained through post-intervention (d = 0·03). The change from baseline to post-intervention corresponded to a medium effect size (d = 0·55). CONCLUSIONS Findings generally support the feasibility of implementing taste testing and point-of-purchase prompting to increase the selection of healthy food items from food trucks; implications for future research in this novel setting are discussed.

Abstract
BACKGROUND Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Testing the effects of interventions to increase consumption of fruit and vegetables, including those focused on specific child-feeding strategies or broader multicomponent interventions targeting the home or childcare environment is required to assess the potential to reduce this disease burden. OBJECTIVES To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 January 2020. We searched Proquest Dissertations and Theses in November 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials. SELECTION CRITERIA We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures. MAIN RESULTS We included 80 trials with 218 trial arms and 12,965 participants. Fifty trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education only in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 23 of the 80 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption, equivalent to an increase of 5.30 grams as-desired consumption of vegetables (SMD 0.50, 95% CI 0.29 to 0.71; 19 trials, 2140 participants; mean post-intervention follow-up = 8.3 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.32, 95% CI 0.09 to 0.55; 9 trials, 2961 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.34 cups of fruit and vegetables a day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.13, 95% CI -0.02 to 0.28; 11 trials, 3050 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) or unintended adverse consequences of interventions (2 trials), limiting our ability to assess these outcomes. Trials reported receiving governmental or charitable funds, except for four trials reporting industry funding. AUTHORS' CONCLUSIONS Despite identifying 80 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited in terms of quality of evidence and magnitude of effect. Of the types of interventions identified, there was moderate-quality evidence that multicomponent interventions probably lead to, and low-quality evidence that child-feeding practice may lead to, only small increases in fruit and vegetable consumption in children aged five years and under. It is uncertain whether parent nutrition education or child nutrition education interventions alone are effective in increasing fruit and vegetable consumption in children aged five years and under. Our confidence in effect estimates for all intervention approaches, with the exception of multicomponent interventions, is limited on the basis of the very low to low-quality evidence. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

Weighed Plate Waste Can Accurately Measure Children's Energy Consumption from Food in Quick-Service Restaurants. J Nutr 2020; 150:404-410. [PMID: 31586209 DOI: 10.1093/jn/nxz222] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/26/2019] [Accepted: 08/22/2019] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Quick-service restaurants (QSRs) serve one-third of US children on any given day, yet no methods can directly measure energy (kcal) consumed in QSRs. Weighed plate waste is one feasible option, but the accuracy is unknown. OBJECTIVE The objective of this study was to determine the accuracy of weighed plate waste for measuring children's energy consumption in QSRs. METHODS Children's plate waste (entrées and sides) was collected for a larger study assessing a community-wide health messaging campaign to inform parents' orders for children in QSRs; a subsample (n = 194) was used for validation. Gross energy left over estimated by weighed plate waste combined with restaurant-stated nutrition information was compared to gross energy determined by bomb calorimetry, the gold-standard energy assessment technique. Analyses were conducted at the meal level (all food items, combined) and stratified by the number of items per meal (1, 2, or 3). Pearson correlations and paired t tests analyzed agreement; Bland-Altman statistics examined differences between energy estimations for the total and stratified subsample. RESULTS Overall, significant agreement was observed between weighed plate waste and bomb calorimetry (r = 0.99, P < 0.001). On average, weighed plate waste underestimated energy content by <2 kcal compared with bomb calorimetry (mean percent difference ± SD of 0.3% ± 10.7%); 94% of estimations fell within the limits of agreement (-23.5 to 26.8 kcal), and 63% and 24% of estimations differed by <10 or <20 net kcal, respectively. Although stratification by item number showed slight variation, mean differences for all strata were <5 kcal (t test P > 0.80), suggesting the accuracy of weighed plate waste for measuring meals of various sizes. CONCLUSIONS Weighed plate waste is an accurate and valid field technique for measuring children's energy consumption from food in QSRs. Future improvements to capturing beverages, self-serve condiments, and sharing behaviors may improve the overall feasibility and accuracy.

Abstract
BACKGROUND Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Interventions to increase consumption of fruit and vegetables, such as those focused on specific child-feeding strategies and parent nutrition education interventions in early childhood may therefore be an effective strategy in reducing this disease burden. OBJECTIVES To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 August 2019. We searched Proquest Dissertations and Theses in May 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials. SELECTION CRITERIA We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures. MAIN RESULTS We included 78 trials with 214 trial arms and 13,746 participants. Forty-eight trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 20 of the 78 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is very low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption equivalent to an increase of 4.45 g as-desired consumption of vegetables (SMD 0.42, 95% CI 0.23 to 0.60; 18 trials, 2004 participants; mean post-intervention follow-up = 8.2 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.34, 95% CI 0.10 to 0.57; 9 trials, 3022 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.36 cups of fruit and vegetables per day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.12, 95% CI -0.03 to 0.28; 11 trials, 3078 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) and unintended adverse consequences of interventions (2 trials), limiting their assessment.

There was very low-quality evidence that child-feeding practice may lead to, and moderate-quality evidence that multicomponent interventions probably lead to small increases in fruit and vegetable consumption in children aged five years and younger. It is uncertain whether parent nutrition education interventions are effective in increasing fruit and vegetable consumption in children aged five years and younger. Given that the quality of the evidence is very low or low, future research will likely change estimates and conclusions. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review.

Abstract
Obesity and metabolic syndrome are considered major public health problems, and their negative impact on cardiovascular disease (CVD) and diabetes mellitus type 2 (DM2) is profound. Targeting modifiable risk factors such as dietary habits is therefore of great importance. Many of today’s health challenges with overweight and obesity may have behavioral roots, and traditional methods such as regulations and campaigns are often insufficient to improve dietary choices. Nudging or choice architecture might be a viable tool to influence people’s everyday choices and behaviors to better outcomes. This paper reviews the current state of the rapidly expanding number of experimental field studies that investigate the effects/associations of nudging on healthy food choices. A systematic literature search was conducted in PubMed, where 142 citations were identified. Based on selection criteria, six randomized controlled trials and 15 non-randomized controlled trials were ultimately included. The results of this systematic review show that many of the studies included traffic-light labeling, which may be a promising strategy. The reviewed findings, however, also highlight the challenges that confront experimental studies examining the impact of nudging on diet.
