Abstract
Added-sugar consumption in the U.S. exceeds recommended limits. Policymakers are considering requiring restaurants to use menu warning labels to indicate items high in added sugar. We sought to determine whether icon-only and icon-plus-text added-sugar menu labels were (1) perceived as more effective at potentially reducing consumption of items high in added sugar and (2) increased knowledge of menu items' added-sugar content relative to control labels, and if effects differed by label design. A national sample of U.S. adults (n = 1327) participated in an online randomized experiment. Participants viewed menu items with either a control label, 1 of 6 icon-only labels, or 1 of 18 icon-plus-text labels with 3 text variations. For their assigned label, participants provided ratings of perceived message effectiveness (a validated scale of a message's potential to change behavior). Participants were also asked to classify menu items by their added-sugar content. The icon-only and icon-plus-text labels were perceived as more effective than the control label (means: 3.7 and 3.7 vs. 3.1, respectively, on a 5-point scale; p < 0.001). The icon-only and icon-plus-text groups each correctly classified 71% of menu items by added-sugar content vs. 56% in the control group (p < 0.001). All icons and text variations were perceived as similarly effective. In conclusion, relative to a control label, icon-only and icon-plus-text added-sugar menu labels were perceived as effective and helped consumers identify items high in added sugar. Menu warning labels may be a promising strategy for reducing added-sugar consumption from restaurants, but research on behavioral effects in real-world settings is needed.

Abstract
As COVID-19 escalated globally in 2020, mandated suspension of dine-in services was instilled to control virus transmission. Restaurants lost billions of dollars, millions experienced severe employment changes, and numerous small restaurants closed. For those remaining in business, converting to online food ordering was essential. Unique to the food ordering setting, this study extended the Stimulus-Organism-Response model to predict the purchase intentions of participants in an online food ordering context. Using structural equation modeling, this study discovered the indirect effects of the menu's visual appeal and informativeness, and the perception of COVID-19 risks on consumer purchase intentions. This causal relationship was significantly mediated by consumers' desire for food and their perceived convenience of online food ordering. Through providing theoretical and managerial implications for how to identify appropriate products, utilize content marketing effectively, and attract new customers, this study could assist restaurants in adapting to remaining competitive, even post COVID-19.

Abstract
Consumers have difficulty using nutrition information. We hypothesized that graphically delivering information of select nutrients relative to a target would allow individuals to process information in time-constrained settings more effectively than numerical information. Objectives of the study were to determine the efficacy of the graphical method in (1) improving memory of nutrient information and (2) improving consumer purchasing behavior in a restaurant. Values of fiber and protein per calorie were 2-dimensionally plotted alongside a target box. First, a randomized cued recall experiment was conducted (n=63). Recall accuracy of nutrition information improved by up to 43% when shown graphically instead of numerically. Second, the impact of graphical nutrition signposting on diner choices was tested in a cafeteria. Saturated fat and sodium information was also presented using color coding. Nutrient content of meals (n=362) was compared between 3 signposting phases: graphical, nutrition facts panels (NFP), or no nutrition label. Graphical signposting improved nutrient content of purchases in the intended direction, whereas NFP had no effect compared with the baseline. Calories ordered from total meals, entrées, and sides were significantly less during graphical signposting than no-label and NFP periods. For total meal and entrées, protein per calorie purchased was significantly higher and saturated fat significantly lower during graphical signposting than the other phases. Graphical signposting remained a predictor of calories and protein per calorie purchased in regression modeling. These findings demonstrate that graphically presenting nutrition information makes that information more available for decision making and influences behavior change in a realistic setting.
