In 2020, following the death of George Floyd and the renewed national focus on racism, many food brands with racist names and packages announced they would rebrand. Brands differed in their extent of rebranding (some only removed an image, whereas others also changed a brand name) and differed in the reasons they gave for the rebranding in PR statements and news interviews. At this point, little is known about how consumers responded to these branding changes. To address this, we conducted an online experiment using the case of Aunt Jemima pancake mix to evaluate how changes in the extent of rebranding and the reason for rebranding impact consumers' likelihood of purchase, expected taste, brand liking, and brand trust. We find that removing the image of Aunt Jemima brought moderate reductions to likelihood of purchase and expected taste and no changes to brand liking or brand trust. When the brand name was also changed to Pearl Milling Company we find larger reductions to likelihood of purchase and expected taste and reductions to brand liking and brand trust. Additionally, we find that informing consumers the change was done to address racism partially mitigated losses in likelihood of purchase following renaming the brand but provided no protection when only the image was removed. The information also had no impact on expected taste, brand liking, or brand trust following either image removal or brand name change. Last, we find evidence of heterogeneity in consumer responses across political ideologies, with liberals reacting more positively to the rebranding and conservatives reacting more negatively.

To determine the rates of episodic and persistent food insecurity among college students and whether coping strategies employed differs on the basis of food security status. Online cross-sectional survey administered in March 2021. A large Midwestern university. A random sample of students (n = 5,000) were invited to participate via email with a response rate of 20% (n = 888). Food insecurity was assessed using the 10-item US Department of Agriculture Adult Food Security Survey Module. Food acquisition and management coping strategies were measured using modified questionnaires. Pearson's chi-squared tests, 1-way ANOVAs, and post hoc analyses were conducted to examine associations of sociodemographic factors and coping strategies with food security status. Linear regression models were used to estimate the association between the coping strategies scale and subscales with food insecurity status. The food insecurity rate was 22%, with 11% and 10% of students experiencing episodic and persistent food insecurity, respectively. Coping strategies varied significantly by food security status (P < 0.001), with students facing persistent food insecurity employing coping strategies most frequently. Future research is needed to better understand the persistent nature of food insecurity and coping strategies to develop tailored policies and programs for the college student population.

The COVID-19 pandemic upended how many Americans acquire foods. In this paper, we analyze eight food acquisition activities at different points in the pandemic, which allows us to evaluate how food acquisition changed as case rates changed and vaccine rollouts occurred. We collected data from three nationally representative online samples in September 2020, December 2020, and March 2021. We evaluate changes across time and across demographics using a multivariate probit model. Across time, we find that in-person grocery shopping remained extremely common (over 90%) throughout the pandemic. Food acquisition activities with less in-person contact (e.g., ordering from a meal kit service, online grocery shopping) peaked in December 2020, likely due to the surge in cases during that period. Ordering take-out from a restaurant remained common throughout the pandemic, but indoor dining increased significantly in March 2021 when vaccines were becoming more widely available. Food acquisition activities also varied across consumer groups, particularly indoor and outdoor restaurant dining. Overall our results offer evidence that in-person grocery shopping is a staple food acquisition activity that is unlikely to be changed; however, there is a segment of consumers who complement their in-person grocery shopping with online grocery shopping options. Further, relative to grocery stores, restaurants may be more vulnerable to surges in COVID-19 case rates. We conclude with implications for grocery retailers and restaurants as they continue to navigate operational challenges associated with the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Purpose: Compare consumers' overall label comprehension of the original Nutrition Facts (NF) label with the updated label. Design: Online survey conducted in 2019. Participants randomly assigned to original label, updated-single column, or updated-dual column labeling condition and asked to complete a series of label comprehension questions. Setting: Online survey; participants recruited through Prolific. Sample: N = 992 U.S. adults. Sample similar to U.S. population in terms of sex (49.2% female), race (73.3% White/Caucasian), and household size (mean = 2.7 members). However, sample was younger (median age: 29.0), more educated (98.8% high school graduate or higher), and exhibited a lower rate of obesity (22.6% obese) than the U.S. population. Measures: Dependent variables: objective (% correct) NF label comprehension. Independent variables: label condition, nutrition knowledge, and socio-demographic variables. Analysis: Regression analysis assessed relationships between label condition and label comprehension. Significance level of 5% used for analyses. Results: Average score for objective comprehension was 81.4%. The updates did not significantly improve label comprehension. Participants in the updated NF label conditions had trouble answering questions related to total and added sugars. Conclusions: Results suggest consumers may struggle to correctly utilize information on the updated NF label, specifically total and added sugars. Consumers may benefit from educational opportunities on using the new label. [ABSTRACT FROM AUTHOR]

Obesity and food waste are related issues, both exacerbated by an overabundance of food. Efforts to reduce food waste can have varying unintended, obesity-related consequences, which further underscores the need for a systems approach to food waste reduction. Yet, these 2 issues are rarely examined together. It is the authors' point of view that for nutrition educators and other public health practitioners to develop interventions that simultaneously address food waste and obesity, they need to understand how actions at the consumer-level may impact waste and its related food system consequences earlier in the supply chain.

The Nutrition Facts (NF) label was recently updated and now includes the added sugars content in an effort to reduce added sugars consumption. This study investigated whether consumers wanted to access or avoid the added sugars content using an online experiment and five product categories (yogurt, cereal, fruit juice, snack bar, ice cream). We recruited a sample of 490 U.S. adults (49% female; 73% White/Caucasian). Respondents were randomly assigned to an information treatment (simple or full) before making decisions on whether to access or avoid the added sugars content. The simple information treatment explained that added sugars information was now available on the NF label, while the full information treatment included additional details (e.g., how to interpret the added sugars content and associated diseases). After making the access or avoid decisions for each product category, respondents rated their likelihood of purchase for ten products (two per category). Rates of information avoidance were much lower than what has been observed in previous studies, and rates of avoidance did not vary by information treatment. The majority of respondents (75–87% across the five product categories) preferred to access the added sugars content. Still, we found some consumers preferred to avoid this information, with higher rates of avoidance for the ice cream product category. Additionally, we found significant differences in likelihood of purchase ratings between information accessors and avoiders. Respondents who chose to access the added sugars information exhibited healthier purchasing behaviors for all product categories; they were more likely to purchase low added sugars products and less likely to purchase high added sugars products relative to information avoiders. Given consumers' demonstrated interest in accessing the added sugars content, it is important that the new changes to the NF label be broadly communicated to promote healthy eating behaviors.

Food waste has drawn increasing public attention, and the high levels of estimated waste are largely considered to be a failure of our current food system. Recently, economists have begun to weigh in, showing food waste can emerge as the result of a complex equilibrium affected by consumers' preferences for convenience; expectations about future food prices and availability; food safety concerns; producers' costs of holding inventory, transportation, and storage; government regulation; and technology. If food waste is a form of inefficiency, there are either strong economic motivations to reduce waste, or unmeasured costs or preferences affecting waste decisions. If consumers have behavioral biases, suffer from information asymmetries, or do not pay the full cost of their waste, there may be a role for government intervention to reduce waste, but most empirical models in the literature have not articulated or quantified the extent of the deadweight loss from the market failures in relation to food waste. In some cases, waste reduction efforts could harm producers if overall demand for food is reduced or harm consumers if overconsumption is encouraged, quality or safety degrades, or supply disruptions occur. Technological innovations, which lower the cost of storage or extend shelf life have the potential to improve both consumer and producer welfare. [ABSTRACT FROM AUTHOR]

Background: School meal programs have a large reach and thus are ideal environments in which to implement interventions targeting improved youth eating behaviors and reduced food waste. This systematic review summarizes the evidence on the effectiveness of school meal nudge interventions on influencing children's eating and waste behaviors. Methods: Inclusion criteria required studies have participants in primary or secondary school (grades K-12) with interventions that occurred during school lunch or breakfast in the cafeteria and included at least one of the following outcomes: selection, consumption, waste, or school meal participation. Analyses of intervention outcomes were restricted to studies of strong and moderate quality. Results: Twenty-nine studies were included in the quality assessment. Included interventions fell into three categories: 1) placement/convenience, 2) marketing/promotion, or 3) variety/portions. The 20 strong and moderate quality studies included in outcome analyses generally used strong data collection methods and study designs, but were limited by an overall lack of intervention fidelity checks. Multi-component interventions often did not use methods that allowed for separate analyses of outcomes for different intervention components. Conclusions: School meal nudge interventions were positively associated with food selection, and had an inconsistent relationship with food consumption. There were few studies evaluating the impact of nudge interventions on meal participation or food waste. The limited evidence available links nudges to improved meal participation, as well as undesirable increases in food waste. Future research in this area should use methods that incorporate implementation metrics, attend to systems factors, and allow the outcomes of individual intervention components to be isolated.

Objectives: Literature suggests that college (ie, post-secondary) students experience food insecurity (FI) at alarming rates. However, the commonly used FI questionnaires have undergone limited evaluations for accuracy in this sub-population. The objective of this exploratory study was to evaluate if FI estimates among college students differ by survey distribution modality. Methods: A test-retest study was conducted from October to December 2017. A random sample of undergraduate students (N = 343) participated in an online survey. After completing the survey, a random sample of these students (N = 66; 29%) completed the same items in paper-and-pencil format. Responses were compared with percent agreement and kappa (κ) coefficients. Results: Students were less likely to affirm each item on paper-and-pencil questionnaires. Percent agreement ranged from 71.2% to 96.9% across items, and κ coefficients ranged from poor to fair. FI prevalence differed by 15% between online and paper-and-pencil assessments (40.9% and 25.8%, respectively). Percent agreement for FI categorization was 75.8% and κ=0.47. Conclusions: Differing survey modalities resulted in varying FI classifications in a sample of undergraduate students. Though limited by size and representativeness, this supports the need for further testing of FI surveys, as accurate FI estimates are essential to serving college students. [ABSTRACT FROM AUTHOR]

A growing body of literature suggests that post-secondary students experience food insecurity (FI) at greater rates than the general population. However, these rates vary dramatically across institutions and studies. FI assessment methods commonly used in studies with college students have not been scrutinized for psychometric properties, and varying protocols may influence resulting FI prevalence estimates. The objective of this study was to assess the performance of standard food security assessment protocols and to evaluate their agreement as well as the relative accuracy of these protocols in identifying student FI. A randomized sample of 4,000 undergraduate students were invited to participate in an online survey (Qualtrics, LLC, Provo, Utah, USA) that evaluated sociodemographic characteristics and FI with the 2-item food sufficiency screener and the 10-item USDA Adult Food Security Survey Module (FSSM; containing the abbreviated 6-item module). Four hundred sixty-two eligible responses were included in the final sample. The psychometric analysis revealed inconsistencies in college student response patterns on the FSSM when compared to national evaluations. Agreement between FI protocols was generally high (>90%) but was lessened when compared with a protocol that incorporated the 2-item screener. The 10-item FSSM with the 2-item screener had the best model fit (McFadden's R2 = 0.15 and Bayesian Information Criterion = -2049.72) and emerged as the tool providing the greatest relative accuracy for identifying students with FI. Though the 10-item FSSM and 2-item screener yields the most accuracy in this sample, it is unknown why students respond to FSSM items differently than the general population. Further qualitative and quantitative evaluations are needed to determine which assessment protocol is the most valid and reliable for use in accurately identifying FI in post-secondary students across the U.S. [ABSTRACT FROM AUTHOR]

The objective of the MealSim study is to empower school nutrition directors with evidence-based strategies specific to their institution to improve student fruit and vegetable consumption while decreasing food waste through the development and evaluation of a school meal systems agent-based model simulation tool. The project aims to improve fruit and vegetable consumption and reduce food waste. Research activities will be conducted through two key objectives: Build an agent-based model (MealSim) to simulate dietary behavior in school meal systems and validate MealSim using data from school nutrition programs in collaboration with key stakeholders. Year three focused on analyzing qualitative data from key stakeholders who provided feedback on MealSim, identifying priorities for model adaptations based stakeholder input, and revising model validation procedures due to COVID-related changes to school nutrition programs. School nutrition stakeholders viewed the MealSim interface positively and reported several potential uses for the simulation tool, such as advocating for policy changes and various training/educational purposes. Stakeholders suggested that additional features be added to MealSim to better represent the school nutrition environment, such as more nuanced time use and number of staff supervising students during lunch. Lunch period structured observation protocols were revised to better differentiate between seated lunch time and other lunch period time uses, as requested by stakeholder feedback. Plate waste assessment protocols were modified to adapt to COVID-related changes and supply chain challenges to school nutrition programs. Adapting MealSim according to stakeholder feedback will facilitate trust in the tool and likely improve its utility. It is anticipated that MealSim will empower school nutrition stakeholders to make evidence-based decisions on how to modify their cafeteria operations to improve fruit and vegetable consumption and reduce food waste, ultimately resulting in improved public and planetary health. 2020-68015-30735 This work is supported by the USDA National Institute of Food and Agriculture.

Background Nutrition labels at the point of purchase are recommended to improve food choice, yet food choice does not always translate into food consumption. It is important to understand the relationship between label use, food selection, servings, and consumption. Previous research, which has relied on self-reported intake or inferred label use or intake based on sales data, has not adequately answered this question. Objective To combine survey and meal photographic data to compare food selection, servings, and consumption between label users and nonusers. Design Diners were surveyed in two cross-sectional waves during the fall 2014 semester. Food selections were recorded, and pre- and postmeal photographs were taken of diners’ plate. Photographs were coded to identify the selection, servings, and consumption of MyPlate food categories. Participants/setting Convenience sample of 1,069 diners (39% women, 53% freshman) in two university dining halls. Students had to be older than age 18 years and just beginning their meal to participate. Main outcome measures Selection, servings, and consumption of MyPlate food categories for label users and nonusers. Statistical analyses performed Differences in food selection were tested via χ 2 tests, and differences in adjusted least squares means for servings and consumption were tested via t tests. Results A greater proportion of nutrition label users selected fruits, vegetables, and beans and fewer selected potatoes compared with nonusers. In addition, fewer label users selected fried foods and foods with added sugars (all P values <0.05). Label users served themselves and consumed more vegetables and fewer potatoes and refined grains compared with nonusers (all P values <0.05). Conclusions Our results suggest label users behave differently compared with nonusers. Based on the meals observed, these differences appear more qualitative in nature (selecting different foods) than quantitative (selecting more or less food). [ABSTRACT FROM AUTHOR]

Consumers' perceptions and WTP values suggest that many individuals see vertical farming as a comparable--and perhaps acceptable--form of agricultural production. WTP for vertically farmed lettuce was similar to that of greenhouse or field-grown lettuce. In addition, consumers rated the safety and expected quality of produce from all three production systems similarly. We see this as evidence that consumers largely fail to distinguish between these agricultural production methods when purchasing lettuce. That being said, it should be noted that study participants still rated vertically farmed lettuce as significantly less natural and significantly less likely to be purchased by the average consumer than other alternatives. Thus, while vertical farming may be one marketable solution to the problem of slowing yield growth and limited food supplies in the future, producers and retailers alike need to be prepared for hesitation on the part of consumers--a common occurrence with the introduction of many new food technologies (Bieberstein et al., 2013; Grunert, Bredahl, and Scholderer, 2003; Henson, 1995; Honkanen and Verplanken, 2004; O'Connor et al., 2006; Sparks, Shepherd, and Frewer, 1994).

The article discusses a study which examined spice and herb (S/H) use with vegetables and its relation to consumer characteristics in the U.S. Topics covered include the frequent use of S/H by younger Asian/Pacific Islander consumers, the higher S/H use when cooking vegetables among women and the potential benefit of interventions encouraging S/H use with vegetables to low-income male and white respondents.

Background Nutrition labels may be important predictors of dietary selections among college students; however, awareness and use are not well understood in this population. Objective The aim of this work was to investigate the influence of label placement on label awareness and use, including influences over time. We also aimed to identify predictors of awareness and use, preferred label information, and reasons for label nonuse. Design Cross-sectional surveys were administered in three 1-week waves over 3 months. Participants/setting Two thousand seven hundred twenty-nine students aged 18 years or older in four university dining halls. Intervention Nutrition labels were placed on sneeze guards in two dining halls and directly in front of food in two comparator dining halls. Main outcome measures Label awareness and use were measured using 5-point Likert scales. Reasons for label nonuse and preferred types of information were assessed by response frequencies. Statistical analysis performed Logistic regression was used to determine predictors of label awareness and use. To test for differences in information preferences between label users and nonusers, χ 2 tests were used. Results Nutrition label awareness and use did not vary by label placement or over time. Awareness was related to being obese, having higher perceived stress, taking nutrition classes, having good/excellent eating habits, eating breakfast, tracking food intake, and exercising five or more times per week. Use was related to being a woman, being overweight, having higher perceived stress, having good/excellent eating habits, eating breakfast, tracking food intake, and exercising three or more times per week. Information preferences differed by use, but calories, fat, and protein were the most preferred pieces of information overall. Not caring, already having a good idea about nutrition information, and not having time were the top reasons for label nonuse. Conclusions Label awareness and use did not change with label placement or over time. Making labels easy to read and including preferred information may encourage greater awareness and use.

The organic label has been studied extensively in the literature; however, few studies take into consideration the context in which the organic purchase takes place. In this study, we examine the product type (virtue vs. vice) as well as the purchase context (retailer: Target vs. Walmart). Using an online experiment with U.S. consumers ( N = 605), we determine how the organic label interacts with each of these contexts and how these interactions impact downstream evaluations such as expected taste, nutrition, safety, likelihood of purchase, and attitude and trust toward the product’s brand. Results of the study reveal both the organic label and retail context impact product evaluations. First, results showed organic products were perceived more favorably on a number of measures (including nutrition, safety, brand attitude, and brand trust) than their non-organic counterparts, providing evidence of an organic “halo” effect. Interestingly, though, the organic “halo” did not extend to two measures: expected taste and likelihood of purchase. Secondly, organic labeling benefits virtue and vice products in distinct aspects – the organic virtue product had better expected taste while the organic vice product had higher expected nutrition. Finally, we find that retailers are a crucial factor that moderates the evaluation of organic products. Our results suggest retailers like Target may be better outlets for promoting organic vice products whereas retailers like Walmart may only be good outlets for promoting organic virtue products. This study has important implications for the National Organic Program, the Organic Trade Association, producers, and food brand managers. [ABSTRACT FROM AUTHOR]

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.

Highlights: [•] We examine the level of item variety and category variety at restaurant tables. [•] Diners are more likely to seek item variety than category variety. [•] Diners are happier if another diner orders from the same food category as them. [•] Calorie labels did not influence the marginal utility of calories. [•] Peer effects may outweigh the effects of nutritional information on food choice. [Copyright &y& Elsevier]

Using field experiment data, we compare the effectiveness of calorie labels to a 'fat tax' at reducing calories ordered. Results from a structural model of consumer demand show that numeric labels did not influence food choice, but symbolic traffic light labels caused restaurant patrons to select lower-calorie menu items; thus, adding a traffic light symbol could enhance the effectiveness of the numeric calorie label (as currently proposed by the Food and Drug Administration). Additionally, our model projects that labels can both reduce intake more than a 10% tax on high-calorie items and a 10% subsidy on low-calorie items. (JEL Q18, I18 ) [ABSTRACT FROM AUTHOR]

In the U.S., the estimated food waste at the household level is 32% of purchased food, translating to $240 billion in economic losses. The U.S. Department of Agriculture and Environmental Protection Agency set the first-ever national food waste reduction goal of a 50-percent reduction by 2030. Under this policy environment, this study assesses public support for nine food waste solutions: changes in food packaging, changes in portion sizes, standardization of date labeling terms, selling imperfect produce in retail stores, making donations easier, using uneaten food to feed animals, implementing composting in communities, consumer education campaigns on food waste, and taxing food waste. An online survey was sent to a nationally representative sample of U.S. respondents that asked about support for and perception of the effectiveness of each food waste solution. This study finds that making donations easier and the standardization of date labels were the most supported food waste solutions. Different food waste solutions appealed to different demographics of people based on their personal food waste experiences. Results are similar for the perception of the effectiveness of each food waste solution. Nevertheless, the percentage of respondents that considered each food waste solution to be effective was almost always less than the share of respondents who supported the solution. Thus, it is important to be cautious about this divergence when assessing public opinion on potential solutions, which may be enacted as policies designed to mitigate food waste.

Background: Recent legislation has required calorie labels on restaurant menus as a means of improving Americans' health. Despite the growing research in this area, no consensus has been reached on the effectiveness of menu labels. This suggests the possibility of heterogeneity in responses to caloric labels across people with different attitudes and demographics. The purpose of this study was to explore the potential relationships between caloric intake and diners' socio-economic characteristics and attitudes in a restaurant field experiment that systematically varied the caloric information printed on the menus. Methods: We conducted a field experiment in a full service restaurant where patrons were randomly assigned to one of three menu treatments which varied the amount of caloric information printed on the menus (none, numeric, or symbolic calorie label). At the conclusion of their meals, diners were asked to complete a brief survey regarding their socio-economic characteristics, attitudes, and meal selections. Using regression analysis, we estimated the number of entrée and extra calories ordered by diners as a function of demographic and attitudinal variables. Additionally, irrespective of the menu treatment to which a subject was assigned, our study identified which types of people are likely to be low-, medium-, and high-calorie diners. Results: Results showed that calorie labels have the greatest impact on those who are least health conscious. Additionally, using a symbolic calorie label can further reduce the caloric intake of even the most health conscious patrons. Finally, calorie labels were more likely to influence the selection of the main entrée as opposed to supplemental items such as drinks and desserts. Conclusions: If numeric calorie labels are implemented (as currently proposed), they are most likely to influence consumers who are less health conscious -- probably one of the key targets of this legislation. Unfortunately, numeric labels did little for those consumers who were already more knowledgeable about health and nutrition. To reach a broader group of diners, a symbolic calorie label may be preferred as it reduced caloric intake across all levels of health consciousness. [ABSTRACT FROM AUTHOR]

• There is increased interest in food insecurity rates on college campuses. • College food insecurity rates vary widely in the published literature. • No food insecurity measure has been validated for use with college students. • Consistent and comparable measurement is critical for efficient policy design. A growing body of research among college students has estimated remarkably high levels of food insecurity when compared to food insecurity estimates from the general population over the past decade, with recent literature reviews reporting average prevalence rates of 33–51% compared to 9.8% among U.S. adults. Given these high rates of food insecurity, policymakers at the state- and federal-levels are considering legislation to better understand and ultimately alleviate food insecurity in the college student population. Further, the National Postsecondary Student Aid Study will soon collect national surveillance data on college student food insecurity. However, emerging research suggests that existing food insecurity measurement tools may not perform as expected when used with college students. Indeed, there is no food insecurity measure that has been validated for use with college students. The purpose of this commentary is to discuss the current state of food insecurity measurement among college students and set a course for more meaningful measurement in the college-student population that produces consistent and comparable estimates of food insecurity.

While packaging is praised for reducing waste of perishable food products, packaging waste is a growing concern. Its least recyclable type, plastics waste, is increasingly polluting the marine environment and many developing countries are now refusing to take the waste from developed countries. Before responsibility can be established, one has to identify the key producers and consumers. This paper adjusts the packaging waste satellite account in EXIOBASE 3 by combining the official waste data published by the World Bank. Based on input–output methods, we find that the world's top suppliers of plastic packaging waste are the United States, China, and Brazil. Food and beverage products constitute the bulk of the problem. Yet, 21% of these countries' plastic packaging waste is induced export. At the global level, it is 25.8%. About 76.0% of export‐induced plastic packaging waste corresponds to packaging of the exported goods that will ultimately be disposed of in the destination country; while the others correspond to the packaging used in their supply‐chain and wasted domestically. We conclude that international efforts need to assign shared responsibility and promote improvement in plastic packaging recyclability. [ABSTRACT FROM AUTHOR]

To obtain feedback from school nutrition stakeholders on an agent-based model simulating school lunch to inform model refinement and future applications. Qualitative study using online discussion groups. School nutrition professional stakeholders across the US. Twenty-eight school nutrition stakeholders. Perceptions and applicability of MealSim for school nutrition stakeholders to help reduce food waste. Deductive approach followed by inductive analysis of discussion group transcripts. Stakeholders appreciated the customizability of the cafeteria characteristics and suggested adding additional characteristics to best represent the school meal system, such as factors relating to school staff supervision of students during meals. The perceived utility of MealSim was high and included using it to train personnel and to advocate for policy and budgetary changes. However, they viewed MealSim as more representative of elementary than high schools. Stakeholders also provided suggestions for training school nutrition administrators on how to use MealSim and requested opportunities for technical assistance. Although agent-based models were new to the school nutrition stakeholders, MealSim was viewed as a useful tool. Application of these findings will allow the model to meet the intended audience's needs and better estimate the system. [ABSTRACT FROM AUTHOR]

A growing body of evidence suggests that post-secondary (i.e. college) students in the US are at higher risk of food insecurity (FI) than the general population. However, the accuracy of the common assessment procedures has come into question. Evidence suggests that pairing the 10-item Food Security Survey Module (FSSM) with a brief screener may produce the most accurate estimates, but this protocol has thus far not been adopted in the field to understand correlates of FI among students. The current study aims to estimate behavioral and health-related correlates of FI using the suggested protocol – incorporating a two-item screener with the 10-item FSSM. Undergraduate students, aged 18- to 24-years old and fluent in English were recruited from a land-grant university using digital advertisements. During the cross-sectional study, participating students completed questionnaires and anthropometric data was collected by trained researchers. Questionnaires assessed FI, perceived stress, diet quality, perceived health, grade point average (GPA), and financial anxiety. Anthropometric data was used to calculate Body Mass Index (BMI). Differences between secure and insecure students were assessed with student's t-tests. Among the preliminary sample of n = 74 participants, students were on average 20.2 years old (± 1.4), predominantly male (55%), and 48.7% experienced FI. Food insecure students reported significantly greater perceived personal stress (P =.011), higher financial anxiety (P <.001), and poorer diet quality (P =.032). However, there was no significant difference between secure and insecure students related to their BMI, achieved GPA, and self-rated health. These preliminary findings suggest that students experiencing FI consume poorer quality diets and experience greater stress and financial anxiety when compared with secure students. These results are consistent with some of the previous findings when researchers have used the 10-item FSSM without the screening items. Further research that uses this FI assessment protocol with a larger sample of students from a variety of institutions is warranted. None. [ABSTRACT FROM AUTHOR]

Children's willingness to try (WTT) foods is positively associated with dietary quality. Sensory characteristics of foods are likely to contribute to children's WTT and dietary intake, but there is little research investigating how sensory characteristics inform vegetable consumption in real-world settings. To investigate the relationship between students' vegetable sensory perception questionnaire responses and vegetable consumption during school lunch. This repeated cross-sectional study collected data at 3 rural Illinois schools over 3 months (3 dates at 2 schools, 2 dates at 1 school) when broccoli or peas were served. Schools participated in the National School Lunch Program and had students in grades K-8. Vegetable consumption was measured by individual direct weighing of waste remaining from standardized vegetable portions. Questionnaire data used a 3-point scale, adapted from USDA Try-Day Taste-Testing Ballots, to assess if students tried the vegetable and WTT vegetable again, and allowed students to rate the vegetable's visual appeal and taste. Descriptive statistics were used to characterize the study sample. Linear regression analyses (adjusted for grade, sex, and percent entrée consumption) were used to examine the association between students' questionnaire responses and school lunch percent vegetable consumption. Participants were 51% female and 49% male (n = 317 students, average of n = 40 per month per school). Responses to vegetable taste and visual appeal questions were significant predictors of percent vegetable consumption, such that students who responded positively to the questions consumed 17.1 and 17.8 percentage points more vegetables than those who responded neutrally (β = 17.1 and 17.8, respectively, P <.001). WTT responses significantly predicted vegetable consumption, with students who responded positively consuming 15.0 percentage points more than those who responded neutrally (β = 15.0, P <.001). Students' vegetable sensory perception questionnaire responses are significant predictors of school lunch vegetable consumption. Subsequently, practitioners should consider improving the visual appeal and taste of school meals, and researchers should incorporate sensory perception measures when evaluating school meal interventions.

Background: Food insecurity (FI) - the lack of sufficient access to food to maintain a healthy lifestyle - among college (i.e. post-secondary or higher education institution) students has become a prominent issue in the U.S. However, it is not clear if high rates of FI among students are due to the modern experience in higher education institutions or due to underlying issues in common surveying methods. To understand if there were underlying content validity issues, the present study had two primary research questions: 1) How do students interpret the U.S. Department of Agriculture (USDA) Food Security Survey Module (FSSM) questionnaire items, and 2) How do responses of students experiencing FI compare with the theorized experiences and coping responses?Methods: Thirty-three undergraduate students, aged 18- to 24-years old and fluent in English were recruited from a single 4-year university. During a 60-min session, participants completed the 10-item Adult FSSM and then were cognitively interviewed about their responses using the think-aloud method. Interview transcripts were analysed by two researchers using a collaborative process and basic interpretative approach.Results: Students were on average 19.5 years old (± 1.2 years), the majority were in their freshman or sophomore (i.e., first or second) year, and 67% (n = 22) experienced FI. Results indicated that students' interpretations of key terms - such as "money for more," "balanced meals," and "real hunger" - diverge from expectations. Furthermore, students categorized as food insecure reported experiences and responses to FI that varied from theoretical dimensions of the process.Conclusions: Though limited by sample size and representativeness, the present results indicate that the content validity of the FSSM may be compromised in this population and the managed process of FI may present differently among college students. Further psychometric research on modifications to the FSSM or with new FI assessment tools should be conducted with college students. [ABSTRACT FROM AUTHOR]

The National School Lunch Program (NSLP) reaches over 30.4 million children every school day and can provide roughly one-third of a child's daily energy intake. Understanding the relationship between student characteristics and meal component selection and consumption is critical to mitigating food waste and improving children's eating behaviors. To examine the prevalence of key systems factors, such as time available for lunch and recess timing, and the impact of demographic factors on meal component selection and consumption among children in rural and urban school districts in Illinois. This cross-sectional study examined meal component selection and consumption at four schools throughout central and southern Illinois participating in the NSLP. Selection and consumption data of Kindergarten through 8th-grade students (n = 302) were collected once per school using visual observation to assess selection and individual direct weighing to assess consumption. Descriptive statistics and t-tests were used to characterize the study sample and investigate relationships between gender, meal component selection, and consumption. Study participants were 55% male and 45% female. All schools had recess after lunch periods, except for one kindergarten class, with an average lunch period lasting 24 minutes. Sixty percent of the schools implemented offer vs. serve. Sixty-seven percent of the sample selected flavored milk over white milk; however, gender was not significantly associated with flavored milk selection nor milk consumption (P =.46 and.16, respectively). Differences in flavored and white milk consumption were assessed (mean = 187.6 and 148.4 ml, respectively), and participants consumed significantly more flavored milk (P <.001). An in-depth understanding of factors relating to children's choices and eating behaviors in the school setting can inform cost-effective school nutrition interventions. Results from this study indicate that interventions can be designed to influence more healthful selection or encourage consumption that minimizes food waste. None. [ABSTRACT FROM AUTHOR]

Cooking-related literacy and attitudes may play important roles in preventing and reducing diet-related chronic diseases and nutrition disparities. People living alone are an under-researched but growing population who face above average food insecurity rates. This study's objectives were to 1) test how cooking self-efficacy and attitude are stratified demographically among a sample of people living alone, focusing on variations across gender, age, and food security, and 2) examine how cooking self-efficacy and attitude are associated with two indicators of cooking behavior – cooking frequency and convenience orientation. We draw from a cross-sectional survey analysis of 493 adults living alone in Illinois, USA with validated measures for cooking self-efficacy, attitude, frequency, convenience orientation, and demographic characteristics. Hierarchical linear regression models were used to examine demographic factors explaining variation in self-efficacy and attitude, with attention to interactions between gender, food insecurity, and age. Poisson and OLS linear regression models were used to examine associations between self-efficacy and attitude and cooking frequency and convenience orientation. We find cooking-related self-efficacy and attitude showed strong but distinct associations with cooking frequency and convenience orientation. Overall, food insecure groups had lower self-efficacy than those who were food secure; however, food insecure women had higher self-efficacy than men in similar positions, apart from older-adult women who held particularly low efficacy. Cooking attitudes varied in small ways, notably with food insecure younger and older women possessing more negative cooking attitudes than middle-aged women. This research highlights the importance of understanding the cooking-related orientations of single-living people, while demonstrating that this group's ability to prevent and manage food insecurity is not uniform. These results can inform targeted interventions around food and nutrition insecurity, cooking attitudes, and self-efficacy among single-living populations. [ABSTRACT FROM AUTHOR]

Objectives: We investigated whether the Short Grit Scale (Grit-S) predicted odds of food insecurity (FI) among adults and their children. Methods: A cross-sectional panel of parent-child dyads completed an online questionnaire. Eligible dyads included parents with household income below the 2015 median ($52,250 USD/year) and their self-selected household child between the ages of 13 to 17 years. An online questionnaire assessed: (1) FI using the 18-item Household Food Security Survey Module and the Food Security Survey Module for Youth; (2) perseverance and determination using the validated 8-item Grit-S; and (3) sociodemographic FI predictors. Logit regression models estimated the relationship between odds of FI and predictors among parents and children, separately. Results: Among 252 parents, 61.1% reported household FI. Parents' Grit-S score (N = 179) was associated with a significantly lower odds of household FI (OR= 0.4; 95%CI= 0.2, 0.8; p < .01) while adjusting for established predictors. Mean (±SD) Grit-S was 3.1 (±0.7). Children's Grit-S score (N = 178) was associated with a significantly lower odds of child FI (OR= 0.6; 95%CI= 0.4, 0.9; p < .05) while adjusting for established predictors. Conclusions: Perseverance and determination, also known as "grit," may be one further explanation for why some poor households are food secure. [ABSTRACT FROM AUTHOR]

U.S. consumers, namely young adults, are one of the largest sources of preventable food waste. However, the antecedents of wasted food among young adults in the U.S. are unknown. This study aimed to explore the perceptions, beliefs and behaviors related to wasted food among 18- to 24-year-old adults. Fifty-eight individuals (63.8% female) with an average age of 20.2 y (±1.6) who lived in a residence where they had control over some food purchases (excluding co-op or other communal housing, and living with parents) participated in 75-min focus groups during spring of 2016. Thirty participants lived in residence halls at a university and the remaining 28 lived in off-campus dwellings. Focus group transcriptions were analyzed for themes by two investigators using a constant-comparative approach. Inductive thematic analyses provided insights that were broadly categorized into: 1) awareness and knowledge of wasted food, 2) factors that influence food waste behaviors, and 3) suggested interventions to reduce wasted food. Results provide evidence of heterogeneity in perceptions, beliefs, and behaviors related to wasted food based on dwelling type. Insights from the current study may be used to inform observational or intervention work focused on reducing wasted food by young adults. [ABSTRACT FROM AUTHOR]

Low vegetable intake continues to be a health concern, and strategies to increase vegetable intake have resulted in only small increases. One strategy that has received less attention is the use of seasonings. This study's objective was to determine the impact of seasoning on vegetable selection, liking, and intent to purchase. We conducted a 3-week study in a public café on a university campus. Customers buying a main dish could select a vegetable side (seasoned [SS] or steamed [ST]) at no cost. Based on café data and power analysis (alpha 0.05, 80% power), 2 days per vegetable pair were conducted with carrot, broccoli, and green bean pairs randomized 3 days/week 1 and 3, with normal service week 2. Selection was greater for SS vs ST, n = 335 vs. 143 for all 3 vegetables combined; n = 97 vs 47 for carrots; n = 114 vs. 55 for broccoli; n = 124 vs. 41 for green beans (p < 0.001 Chi-Square). Liking responses were similar for SS vs ST and were high for all vegetables. Response distribution was not significantly different for SS vs ST vegetables when people were asked if they would purchase the vegetable that they selected. More customers chose the 'somewhat likely' and 'very likely' (n = 353) than the 'not likely' and 'definitely would not' (n = 121) purchase responses. Regression showed that people who did not often consume a vegetable with lunch while dining out were 1.59 times more likely to select the SS vegetables over the ST (p = 0.007). Given a choice, consumers were more likely to select a seasoned vegetable. With low vegetable consumption as a predictor of seasoned vegetable choice, offering seasoned vegetables may increase intake in those with poor vegetable intake in a café setting.

Current population-based methods for assessing dietary intake, including food frequency questionnaires, food diaries, and 24-h dietary recall, are limited in their ability to objectively measure food intake. Digital photography has been identified as a promising addition to these techniques but has rarely been assessed in self-serve settings. We utilized digital photography to examine university students' food choices and consumption in a self-serve dining hall setting. Research assistants took pre- and post-photos of students’ plates during lunch and dinner to assess selection (presence), servings, and consumption of MyPlate food groups. Four coders rated the same set of approximately 180 meals for inter-rater reliability analyses; approximately 50 additional meals were coded twice by each coder to assess intra-rater agreement. Inter-rater agreement on the selection, servings, and consumption of food groups was high at 93.5%; intra-rater agreement was similarly high with an average of 95.6% agreement. Coders achieved the highest rates of agreement in assessing if a food group was present on the plate (95–99% inter-rater agreement, depending on food group) and estimating the servings of food selected (81–98% inter-rater agreement). Estimating consumption, particularly for items such as beans and cheese that were often in mixed dishes, was more challenging (77–94% inter-rater agreement). Results suggest that the digital photography method presented is feasible for large studies in real-world environments and can provide an objective measure of food selection, servings, and consumption with a high degree of agreement between coders; however, to make accurate claims about the state of dietary intake in all-you-can-eat, self-serve settings, researchers will need to account for the possibility of diners taking multiple trips through the serving line.

Objective: Nutrition labels are an essential source for consumers to obtain nutrition-related information on food products and serve as a population-level intervention with unparalleled reach. The present study systematically reviewed existing evidence on the correlates of nutrition label use among college students and young adults. Design: Keyword and reference searches were conducted in PubMed, EBSCO, PsycInfo, Cochrane Library and Web of Science. Inclusion criteria included: study design (randomized controlled trial, cohort study, pre-post study or cross-sectional study); population (college students and young adults 18-30 years old); main outcome (nutrition label use); article type (peer-reviewed publication); and language (English). Setting: College/university. Subjects: College students and young adults. Results: Sixteen studies based on data from college surveys in four countries (USA, UK, Canada, South Korea) were identified from keyword and reference search. Reported prevalence of nutrition label use varied substantially across studies; a weighted average calculation showed 36·5% of college students and young adults reported using labels always or often. Females were more likely to use nutrition labels than males. Nutrition label use was found to be associated with attitudes towards healthy diet, beliefs on the importance of nutrition labels in guiding food selection, self-efficacy, and nutrition knowledge and education. Conclusions: The impact of nutrition labelling on food purchase and intake could differ by population subgroups. Nutrition awareness campaigns and education programmes may be important mechanisms for promoting nutrition label use among college students and young adults. Future research is warranted to assess the role of label use on improved dietary decisions. [ABSTRACT FROM AUTHOR]
