“…Various modes of delivery were used, including smartphone apps (n 12, 70•6 %), websites (n 7, 41•2 %) and hardcopy handouts (n 3, 7•3 %) (Table 2). The technology-assisted components of the interventions were designed to improve food choices through self-monitoring (32,33,35,(37)(38)(39)(41)(42)(43)(44) , goal setting (32,33,37,39,41,43) , feedback (32,33,35,37,42,43) , education (33,34,37,45) , inhibitory control (36,40,44,46) , nudging (47,48) and social support (44) .

Making healthy food choices is crucial for health promotion and disease prevention. While there are an increasing number of technology-assisted interventions to promote healthy food choices, the underlying mechanism by which consumption behaviours and weight status change remains unclear. Our scoping review and meta-analysis of 17 studies represents 3,988 individuals with mean ages ranging from 19.2 to 54.2 years old and mean body mass index ranging from 24.5kg/m2 to 35.6kg/m2. Six main outcomes were identified namely weight, total calories, vegetables, fruits, healthy food, and fats and other food groups including sugar-sweetened beverages, saturated fats, snacks, whole grains, sodium, proteins, fibre, cholesterol, dairy, carbohydrates, and takeout meals. Technology-assisted interventions were effective for weight loss (g=-0.29; 95% CI=-0.54, -0.04; I2=65.7%, t=-2.83, P=0.03) but not for promoting healthy food choices. This highlights the complexity in creating effective interactive technology-assisted interventions and understanding its mechanisms of influence and change. We also identified that there needs to be greater application of theory to inform the development of technology-assisted interventions in this area as new and improved interventions are being developed.

“…Limitations of the present study include the relatively homogeneous sample although research from Coffino et al [12–14] and the expansion of SNAP acceptance in the context of online grocery shopping highlight the potential of this approach to extend to lower‐income households. We focused on two grocery stores, choosing two of the largest chains in the region in which the research team was located.…”

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.

“…16 Default options have been shown to increase healthy food orders in a full-service restaurant, 17 as well as healthy food purchases in laboratory-based and online supermarket settings. [18][19][20] Most previous research has had small sample sizes or has not tailored default options to past purchasing decisions. No research has focused on prefilling online shopping carts with fruit and vegetable items.…”

“…This bias can be leveraged to promote health by changing environmental defaults to healthy choices that people can opt out of, such as legislative requirements for restaurants to serve healthy drinks as the default with kid’s meals . Default options have been shown to increase healthy food orders in a full-service restaurant, as well as healthy food purchases in laboratory-based and online supermarket settings . Most previous research has had small sample sizes or has not tailored default options to past purchasing decisions.…”

ImportanceDespite recent growth in online redemption of Supplemental Nutrition Assistance Program (SNAP) benefits, no previous work has tested the impact of economic and behavioral economic strategies on food purchasing behaviors in an online grocery retail setting among adults with low income.ObjectiveTo examine the extent to which financial incentives and default shopping cart options influence fruit and vegetable purchases.Design, Setting, and ParticipantsThis randomized clinical trial used an experimental online grocery store for adults who currently or have ever received SNAP benefits. From October 7 to December 2, 2021, participants were instructed to shop for a week’s worth of groceries for their household, with a budget tailored to household size; no payment was taken.InterventionsRandom assignment to 1 of 4 conditions: no intervention, 50% discount on eligible fruits and vegetables, prefilled shopping carts with tailored fruit and vegetable items (ie, default options), or a combination of the discount and default options.Main Outcomes and MeasuresThe primary outcome was the percentage of nondiscounted dollars spent on eligible fruit and vegetables per basket.ResultsOf 2744 participants, mean (SD) age was 46.7 (16.0) years, and 1447 (52.7%) identified as women. A total of 1842 participants (67.1%) reported currently receiving SNAP benefits and 1492 (54.4%) reported shopping online for groceries in the previous 12 months. Participants spent a mean (SD) 20.5% (23.5%) of total dollars on eligible fruits and vegetables. Compared with no intervention, those in the discount condition spent 4.7% (98.3% CI, 1.7%-7.7%) of more total dollars on eligible fruits and vegetables; those in the default condition, 7.8% (98.3% CI, 4.8%-10.7%) more; and those in the combination condition, 13.0% (98.3% CI, 10.0%-16.0%) more (P &lt; .001 for all). There was no difference between the discount and the default conditions (P = .06), but the effect in the combination condition was significantly larger than both discount and default conditions (P &lt; .001). Default shopping cart items were purchased by 679 participants (93.4%) in the default condition and 655 (95.5%) in the combination condition, whereas 297 (45.8%) in the control and 361 (52.9%) in the discount conditions purchased those items (P &lt; .001). No variation was observed by age, sex, or race and ethnicity, and results were similar when those who reported never shopping online for groceries were excluded.Conclusions and RelevanceIn this randomized clinical trial, financial incentives for fruits and vegetables and default options, especially in combination, led to meaningful increases in online fruit and vegetable purchases among adults with low income.Trial RegistrationClinicalTrials.gov Identifier: NCT04766034
