Abstract
Food waste is a pressing global issue with profound social, environmental, and economic implications, prompting an urgent need for a comprehensive understanding of its sources. In the current study, we explored the role of cultural and personal determinants in food management practices. We operationalized two food practices - prevention of food waste by inventory and meal management and reduction of food waste by leftovers management, and explored how they are shaped by personal and cultural determinants. We asked 1200 respondents, three types of questions about their (1) cultural and personal attributes, such as their ethical and religious values; (2) lifestyle and dietary habits, such as their frequency of eating out, and (3) sociodemographic characteristics. We modeled the association between these three types of questions and the two food management practices utilizing a hierarchical multiple regression model. The results indicate that ascribing significant importance to hospitality is associated with less proficiency in inventory and meal management. Those who place a high priority on hospitality preparedness are proficient in managing leftovers but less proficient in inventory and meal management. In addition, individuals with strong ethical and religious views against food wastage tend to manage their inventory and meals poorly but excel at handling surplus food. Finally, secular Ashkenazi Israelis tend to engage in better practices to prevent and reduce food waste. The results also stress the differences between practices to prevent food waste and those to reduce it, opening a promising avenue for future research.

Abstract
This study investigates the structure of factors that influence consumer intentions to both try and to consume cultured proteins, and their intentions to substitute vegan, vegetarian and omnivore diets with these alternative protein sources. Comprehensive survey data (N = 3862) was collected from three Nordic countries (Denmark, Finland, and Norway) and analysed using confirmatory factor analysis and structural equation modelling. Theoretically, this article draws from behavioural models of environmental psychology, identity theory, and attitude theory. Results indicate that beliefs about the necessity of an industry producing cultured proteins and impacts of cultured proteins on the global economy are significant predictors of consumer intentions. Moreover, participants who exhibited high levels of general and food innovativeness were more likely to express positive intentions to consume cultured proteins. Social norms influenced consumer intentions: Individuals surrounded by positive attitudes and intentions toward cultured proteins within their social networks were more inclined to want to consume these products. The predictor variables in the final model accounted for between 39% and 66% of the variance in the different cultured proteins related intentions. Understanding consumer intentions better can inform targeted communication strategies aimed at promoting the advantages of cultured proteins and facilitating its adoption.

Abstract
In Western countries, a behavioural shift towards more plant-based diets is helpful in protecting population and planet health. School canteens are an important public policy target to achieve this transition. Increasing the frequency of vegetarian meals in school canteens has been proposed as a solution to decrease greenhouse gas emissions while maintaining a good nutritional quality. However, vegetarian meals acceptance by children is key to limit unintended consequences such as increased food waste or increased nutritional inequalities. We aimed to examine children's liking for vegetarian and non-vegetarian main dishes at school canteens; and whether it varied across socioeconomic level. Connected scoring devices displaying a five-point smiley scale were installed in all the 38 primary school canteens of a French city, located in socially diverse neighbourhoods. Every day after their school lunch, children were asked to rate the main dish they had just eaten. During one school year, from September 2021 to June 2022, we collected 208,985 votes for 125 main dishes, including 32 vegetarian (i.e., no meat or fish) and 93 non-vegetarian dishes, for an average of 1672 (SD 440) votes per day across the 38 school canteens. We showed no difference in children's liking for vegetarian and non-vegetarian dishes. Additionally, the socioeconomic level of the schools was found to interact negatively with children's liking for vegetarian main dishes whereby vegetarian main dishes tended to be more liked in schools of lower socioeconomic level. In this French city, children's acceptance would not be a barrier to increase the frequency of vegetarian school meals and would not increase social dietary inequalities.

Abstract
Eating healthily in terms of fruit and vegetable consumption has beneficial effects for employees and their organisations. Yet, we know little about how employees' eating behaviour develops over longer periods of time (trajectories) as well as about how subgroups of employees in these trajectories differ (trajectory classes). Gaining such insights is critical to understand how employees address healthy eating recommendations over time as well as to develop individualised interventions that also consider the development of healthy eating (i.e. improvement versus impairment beyond mean levels). We analysed panel data (Longitudinal Internet Studies for the Social Sciences) from 1054 employees by means of growth mixture modelling. Our analyses revealed three relevant classes of healthy-eating trajectories: a favourable trajectory class, an unfavourable trajectory class and a strongly improving trajectory class. Furthermore, unfavourable healthy-eating trajectories were especially critical with respect to impaired psychological well-being. Specifically, we found robust results for impaired positive and negative affects, but not for self-esteem, in the unfavourable trajectory class. We discuss limitations and implications of these findings, thereby encouraging research and practice to further consider such fine-grained approaches (i.e. focusing on subgroups within a larger population) when addressing healthy-eating promotion over time.

Abstract
BACKGROUND Refugees have a high prevalence of obesity post resettlement, but few studies have compared their risk of obesity to those of the host population. We systematically investigated the association between refugee status and obesity after resettlement in a high-income nation. METHODS We searched PubMed, Embase, OpenGrey and bibliographies of retrieved articles, with no date, location, and language restrictions, for observational studies assessing obesity rates in resettled refugees compared to the host population. RESULTS Nine studies were analyzed. We found no evidence of increased risk of obesity among refugees compared to the host population, with significant heterogeneity across studies. However, the risk of obesity among refugee men were significantly lower than the host population. DISCUSSION The heterogeneity between studies calls for more high-quality research to examine the risk of obesity among refugees compared to the host population in high-income countries. This will enable results to be pooled to provide more decisive evidence about obesity trends among refugees post migration in a high-income nation.

Abstract
Preventing food waste is important. Analyzing the effects of food waste attitudes on urban residents' waste production behaviors is necessary to reduce food waste. As Shanghai is a mega-city with a population of 24 million people, once food is adequately supplied, more attention is paid to the safety of food in terms of quantity, quality, and nutrition. COVID-19 gave a shock to the food supply in Shanghai, which in turn resulted in food waste behavior. The moderating effect of pandemic during the COVID-19 is one that has rarely been mentioned in previous studies. An investigation of urban residents was conducted in Shanghai. A total of 1030 valid questionnaires were collected in October 2020. This study examined the influence of food waste attitudes on food waste behavior under the moderating effects of pandemic expectations, quantity safety, quality safety, and price stability using a multivariate ordered probit model. The results show that food waste attitudes had a significant negative effect on food waste behavior at a p < 0.01 level of significance, which means that the more people feel shame about food waste, the less food waste they will have. The interaction coefficient between food waste attitudes and pandemic expectations was positive at a p < 0.1 level of significance. This paper concludes with strategies for dealing with food waste in the future.

Abstract
There is a reliable association between autism and Feeding and Eating Disorders. Concerningly, where these two conditions co-occur, clinical outcomes of Feeding and Eating Disorders are significantly worse, and treatment less effective, than when the Feeding and Eating Disorders occur in neurotypical individuals. Problematically, the reason for the association between autism and Feeding and Eating Disorders is poorly understood, which constrains advances in clinical care. This paper outlines several possible mechanisms that may underlie the observed association and suggests ways in which they may be empirically tested. Mechanisms are split into those producing an artefactual association, and those reflecting a genuine link between conditions. Artefactual associations may be due to conceptual overlap in both diagnostic criteria and measurement, Feeding and Eating Disorders causing transient autistic traits, or the association being non-specific in nature. A genuine association between autism and Feeding and Eating Disorders may be due to common causal factors, autism directly or indirectly causing Feeding and Eating Disorders, and Feeding and Eating Disorders being a female manifestation of autism.

Abstract
OBJECTIVE To identify common themes of the meaning of food among people who identify with a specific religious tradition, particularly focusing on potential applications for nutrition education and professional practice at multiple levels of the Social-Ecological Model. DESIGN Virtual and in-person focus groups were used to collect qualitative data. SETTING A midsized city in eastern Washington State. PARTICIPANTS Nine focus groups (n = 35), each representing a distinct religious congregation. PHENOMENON OF INTEREST Meaning of food in the context of religion. ANALYSIS Qualitative, reflexive thematic analysis using web-based software to organize data. RESULTS Four key themes were identified that applied to both of the overarching focus group topic areas (general and religious): (1) food fosters connection, (2) food influences health, (3) relationships with food are complicated, and (4) food choices reflect values. Subthemes were specific to topic areas. In religious contexts, the meaning of food was more likely understood at a community level in addition to individual and relational levels of the Social-Ecological Model. CONCLUSIONS AND IMPLICATIONS Acknowledgment and consideration of the religious identities of patients and clients may provide greater opportunities for community connection, which may have potential implications for community-level nutrition interventions.

Abstract
Innate behaviors meet multiple needs adaptively and in a serial order, suggesting the existence of a hitherto elusive brain dynamics that brings together representations of upcoming behaviors during their selection. Here we show that during behavioral transitions, possible upcoming behaviors are encoded by specific signatures of neuronal populations in the lateral hypothalamus (LH) that are active near beta oscillation peaks. Optogenetic recruitment of intrahypothalamic inhibition at this phase eliminates behavioral transitions. We show that transitions are elicited by beta-rhythmic inputs from the prefrontal cortex that spontaneously synchronize with LH 'transition cells' encoding multiple behaviors. Downstream of the LH, dopamine neurons increase firing during beta oscillations and also encode behavioral transitions. Thus, a hypothalamic transition state signals alternative future behaviors, encodes the one most likely to be selected and enables rapid coordination with cognitive and reward-processing circuitries, commanding adaptive social contact and eating behaviors.

Abstract
Background: Childhood obesity is one of the most serious public health epidemics of the 21st century. Observational studies report that increases in portion size (PS) have occurred in parallel with levels of obesity. Increased PSs of high-energy-dense foods can promote overeating, and without compensatory behaviours, can contribute to childhood obesity. Caregivers make decisions about PSs for children in the home and nursery environment, thus are gatekeepers to child food intake. Understanding caregiver PS decisions can aid in the best practice of PS provision to young children. The aim of this study was to explore parent and nursery staff influences on child PS selection and their suggestions for useful tools/strategies in PS decisions. Methods: A qualitative design was employed using focus group discussions (FGDs) with parents and nursery staff of children aged 3-5 years. FGDs were employed given their ability to generate rich data, as well as permit the exploration of collective perceptions, attitudes, behaviours and experiences. Data were analysed using an inductive, semantic approach to reflexive thematic analysis. Results: Four FGDs were conducted: two with parents (n = 13), two with nursery staff (n = 17). Four overarching themes were derived: (i) awareness of PS guidelines; (ii) control over PS; (iii) social influences on children's eating behaviours; (iv) child-specific, social and external factors influencing parent and nursery staff PS decisions. Additionally, participants discussed tools/strategies they believe would be useful in PS decisions. Conclusion: Data from the themes suggest that caregiver control, social, child-specific and external factors are more influential than PS guidelines in both parent and nursery staff PS decisions for young children aged 3-5 years. These findings can inform future childhood obesity prevention initiatives focussed on improving parent and nursery staff provision/use of age-appropriate PSs.

Abstract
BACKGROUND Little is known about motivation for weight loss and barriers to weight loss among patients with idiopathic intracranial hypertension (IIH). Such information is crucial for developing tailored weight management recommendations and novel interventions. METHODS We administered a survey to patients with IIH presenting to neuro-ophthalmology clinics at The University of Michigan Kellogg Eye Center (Michigan, USA) and St. Thomas' Hospital (London, England). Participants rated importance and motivation to lose weight (1-10 scale; 10 = extremely important/motivated). Facilitators and barriers to weight loss were assessed using open-ended survey questions informed by motivational interviewing methodology. Open-ended responses were coded by 2 team members independently using a modified grounded theory approach. Demographic data were extracted from medical records. Descriptive statistics were used to analyze quantitative responses. RESULTS Of the 221 (43 Michigan and 178 London) patients with IIH (Table 1), most were female (n = 40 [93.0%] Michigan and n = 167 [94.9%] London). The majority of patients in the United States were White (n = 35 [81.4%] Michigan), and the plurality were Black in the United Kingdom (n = 67 [37.6%] London]) with a mean (SD) BMI of 38.9 kg/m2 (10.6 kg/m2) Michigan and 37.5 kg/m2 (7.7 kg/m2) London. Participants' mean (SD) level of importance to lose weight was 8.5 (2.2) (8.1 [2.3] Michigan and 8.8 [2.1] London), but their mean (SD) level of motivation to lose weight was 7.2 (2.2) (6.8 [2.4] Michigan and 7.4 [2.1] London). Nine themes emerged from the 992 open-ended coded survey responses grouped into 3 actionable categories: self-efficacy, professional resources (weight loss tools, diet, physical activity level, mental health, and physical health), and external factors (physical/environmental conditions, social influences, and time constraints). Most responses (55.6%; n = 551) were about barriers to weight loss. Lack of self-efficacy was the most discussed single barrier (N = 126; 22.9% total, 28.9% Michigan, and 20.4% London) and facilitator (N = 77; 17.5% total, 15.9% Michigan, and 18.7% London) to weight loss. Other common barriers were related to physical activity level (N = 79; 14.3% total, 13.2% Michigan, and 14.8% London) and diet (N = 79; 14.3% total, 9.4% Michigan, and 16.3% London). Commonly reported facilitators included improvements in physical activity level (N = 73; 16.6% total, 18.5% Michigan, and 15.1% London) and dietary changes (N = 76; 17.2% total, 16.4% Michigan, and 17.9% London). CONCLUSIONS Patients with IIH believe weight loss is important. Self-efficacy was the single most mentioned important patient-identified barrier or facilitator of weight loss, but professional resource needs and external factors vary widely at the individual level. These factors should be assessed to guide selection of weight loss interventions that are tailored to individual patients with IIH.

Scott AG, Johnson BJ, Hunter SC. Exploring the influence of context on social norms around Australian parents' food provision using story completion. Public Health Nutr 2024; 27:e110. [PMID: 38576146 PMCID: PMC11036444 DOI: 10.1017/s1368980024000806] [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: 03/23/2023] [Revised: 03/13/2024] [Accepted: 03/25/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE To explore the differences in social norms around parents' food provision in different provision contexts and by demographics. DESIGN Qualitative study using story completion methodology via an online survey in September 2021. Adults 18+ with or without children were randomised to one of three story stems focusing on food provision in different contexts; food provision at home (non-visitor), with visitors present and with the involvement of sport. Stories were coded and themed using thematic analysis. A content analysis was performed to determine count and frequency of codes in stories by participant demographics and story assumptions. SETTING Australia. PARTICIPANTS Adults (n 196). RESULTS Nine themes were identified from the data resulting in four social norms around providing healthy foods and justifying non-adherence to healthy eating guidelines, evolution of family life and mealtime values, the presence of others influencing how we engage with food provision and unhealthy foods used as incentives/rewards in sport. Following content analysis, no differences of themes or norms by participant demographics or story assumptions were found. CONCLUSIONS We identified pervasive social norms around family food provision and further identified how contextual factors resulted in variations or distinct norms. This highlights the impact context may have on the social norms parents face when providing food to their children and the opportunities and risks of leveraging these social norms to influence food choice in these contexts. Public health interventions and practitioners should understand the influence of context and social environments when promoting behaviour change and providing individualised advice. Future research could explore parents' experiences of these norms and to what extent they impact food choice.

Abstract
Social norm perceptions are implicit standards describing what is typically done or seen as acceptable and have shown to be important both in sustaining meat consumption as well as facilitating meat reduction. Norm perceptions depend on individual differences and the contexts (e.g., supermarket, restaurant). Yet, evidence how norm perceptions differ within and across individuals is scarce. The primary aim of this study was to investigate how descriptive, injunctive, and personal norms perceptions favouring meat consumption differ across contexts and meat consumer groups. The second aim was to investigate how generic dynamic norm perceptions vary across meat consumer groups. British meat eaters (n = 1205, 25-65 years) participated in an online cross-sectional survey. Weekly meat, fish and meat substitute consumption was measured with the adapted Oxford Meat Frequency Questionnaire. All but dynamic norm perceptions were measured for the supermarket, restaurant and worksite cafeteria context. Dynamic norms were measured without a specified context. A two-step cluster analysis was conducted to identify meat consumer groups. Descriptive norm perceptions favouring meat consumption were strongest in supermarket and restaurant contexts, compared to the worksite cafeteria. Injunctive and personal norms favouring meat consumption were both perceived strongest in the supermarket, followed by the restaurant, and least in the worksite cafeteria context. Four meat consumer groups were identified and those with higher meat intake (i.e., Meat lovers and Exceeders) perceived norms favouring meat consumption stronger and norms favouring meat avoidance weaker than the groups with lower meat intake (i.e., Flexitarians and Moderates). While norm perceptions differed between meat consumer groups, the pattern of contextual differences is similar for these meat consumer groups. Our findings underscore the importance of considering contexts and meat consumer groups in efforts to reduce meat consumption.

Abstract
Transitioning towards more plant-based protein diets is essential for public and planetary health. Current research about consumption practices of protein sources provides limited insight in the multidisciplinary nature and interconnectivity of the food environment. This study aimed to collect mental models of review authors by synthesizing both their implicit and explicit system views into an overarching system view. Published reviews were used to select participants and identify variables that explain the protein transition in relation to the food environment. To overcome differences in disciplines and scale levels (e.g. individual, interpersonal, environmental), variables were organized according to the Determinants of Nutrition and Eating Framework. Eight review authors shared their mental models in an interview. Participants were asked to construct a causal loop diagram (CLD), a tool proven valuable in making one's ontology explicit to others. Implicit system views in narrative were converted into CLDs using a coding framework. The overarching system view suggests that a multitude of feedback loops sustain current consumption patterns of protein sources, for example by reinforcement through habit, availability and peer support. Several aspects require further research, such as variable relationships that were subject to disagreement and the lack of reciprocity between the physical and social elements of the food environment. In addition, knowledge gaps were exposed, including long-term behaviour and interaction of multiple variables. As a boundary object, the overarching system view can facilitate the direction of future research. The findings underscore the interconnected nature of many disparate elements within the food environment, stressing the need for holistic methods like systems thinking. These are essential in developing a systemic understanding and facilitating the transition towards more plant-based diets.

Eat Behav 2024; 53:101872.

Abstract
Exposing children to adults eating a raw vegetable with positive facial expressions ('positive modelling') increases children's consumption of the modelled vegetable. However, whether repeated versus a single exposure to positive modelling enhances this effect, and whether it generalises to a non-modelled vegetable, remains to be examined. Hence, this study examined the effect of a single exposure, versus repeated, exposure to positive modelling on children's acceptance and intake of a modelled and non-modelled vegetable. Children aged 5-6 years (N = 153; 81 males, 72 females) were randomised to one of three conditions in which they had i) a single or ii) repeated exposure to a video of adults eating raw broccoli with positive facial expressions or iii) were exposed to a no-food control video. Children's acceptance (measured as willingness to try and number of tastes), intake and liking of a modelled (raw broccoli) and non-modelled vegetable (raw mangetout) were measured. Children had greater raw broccoli consumption and liking if they had received repeated exposure to positive modelling, compared to children who had received a single exposure, but not compared to children in the control condition. Children's mangetout intake was greater in the single (versus repeated) positive condition, but this effect was not dependent on time. There was no effect on children's vegetable acceptance. Repeatedly exposing children to adults enjoying a vegetable encourages children's intake of the modelled vegetable in comparison to a single exposure. Thus, repeated exposure to others' food enjoyment may be a practical and useful strategy to encourage children's vegetable consumption.

Family Meals and Social Eating Behavior and Their Association with Disordered Eating among Spanish Adolescents: The EHDLA Study. Nutrients 2024; 16:951.

Abstract
PURPOSE The aim of this study was to examine the association of family meals and social eating behavior with disordered eating behavior in Spanish adolescents. METHODS This was a cross-sectional study that included 706 adolescents (43.9% boys) from the Eating Habits and Daily Life Activities (EHDLA) study (aged 12 to 17) from Valle de Ricote, Region of Murcia, Spain. The frequency of family meals was assessed by asking participants to report how often their family, or most household members, had shared meals in the past week. Social eating behavior was evaluated using three statements: "I enjoy sitting down with family or friends for a meal", "Having at least one meal a day with others (family or friends) is important to me", and "I usually have dinner with others". To evaluate disordered eating, two psychologists administered the Sick, Control, One, Fat and Food (SCOFF) questionnaire. RESULTS After adjusting for several covariates, for each additional family meal, the likelihood of having disordered eating behavior was lower (odds ratio (OR) = 0.96; 95% confidence interval (CI) 0.93 to 0.9997, p = 0.049). On the other hand, a lower likelihood of having disordered eating behavior was observed for each additional point in the social eating behavior scale (OR = 0.85; 95% CI 0.77 to 0.93, p = 0.001). The likelihood of having disordered eating behavior was 0.7% lower for each additional family meal (95% CI 0.01% to 1.4%, p = 0.046). Furthermore, for each additional point in the social eating behavior scale, a lower probability of having disordered eating behavior was observed (3.2%; 95% CI 1.4% to 5.0%, p < 0.001). CONCLUSIONS While disordered eating behavior is complex and can be shaped by various factors, both family meals and social eating behavior emerge as significant factors inversely associated with this condition among adolescents. Promoting regular engagement in family meals and fostering positive social eating experiences could serve as effective strategies in public health initiatives aimed at mitigating the incidence of disordered eating behavior among the young population.

Abstract
Previous research has shown that being observed can influence people's behaviors, including their eating habits. In this study, we predicted that men and women would exhibit different reactions to the perception of portion size of meat when being observed. By utilizing a camera to create a sense of being observed during the act of eating meat, we revealed that men in the observed condition reported perceiving the portion size of the meat they ate to be smaller and the eating amount to be less than was reported by those in the non-observed condition. However, women did not show any differences in their perceptions of the portion size of the meat they ate. These findings demonstrate that gender identity plays a role in how people perceive the meat they eat when they are aware of being observed. The discussion highlights the effect of being observed on meat consumption and illustrates the influence of masculine identity.

Abstract
EAT-26 questionnaire is used globally to screen people for the risk of eating disorders. In addition to this, the EAT-26 is being used in its original English version in research and clinical settings due to unavailability of the Urdu version. Therefore, the aim of this study was to introduce the Urdu version of EAT-26 to clinicians and academicians in Pakistan, interested in the assessment of population at risk of eating disorders. After getting the formal permission for translation by Dr. D. M. Garner, WHO guidelines were followed for the translation and adaptation process. Two independent translators with psychological background worked under the supervision of a lead to produce the definitive version following six steps of translation and adaptation. Cognitive interviews and focused group discussions helped in the assessment process for the understanding level of translated Urdu version. The pre-final version showed comprehension and acceptability during initial pilot testing.•The final translated version of EAT-26 in Urdu will be available on Internet to use. It is expected that the use of EAT-26 will be widespread in Pakistan, aiming at the assessment of eating disorders.•The Urdu version of EAT-26 is finalized, and ready to use by researchers and clinicians in Pakistan.

Abstract
The hippocampus (HPC), traditionally known for its role in learning and memory, has emerged as a controller of food intake. While prior studies primarily associated the HPC with food intake inhibition, recent research suggests a critical role in appetitive processes. We hypothesized that orexigenic HPC neurons differentially respond to fats and/or sugars, potent natural reinforcers that contribute to obesity development. Results uncover previously-unrecognized, spatially-distinct neuronal ensembles within the dorsal HPC (dHPC) that are responsive to separate nutrient signals originating from the gut. Using activity-dependent genetic capture of nutrient-responsive HPC neurons, we demonstrate a causal role of both populations in promoting nutrient-specific preference through different mechanisms. Sugar-responsive neurons encode an appetitive spatial memory engram for meal location, whereas fat-responsive neurons selectively enhance the preference and motivation for fat intake. Collectively, these findings uncover a neural basis for the exquisite specificity in processing macronutrient signals from a meal that shape dietary choices.

Abstract
(1) Background: There has been a growing interest in understanding the causes of obesity and developing effective prevention strategies. Lifestyle change programs are often considered the gold standard for weight reduction, and they can help individuals with obesity achieve an annual weight loss of around 8-10%. The aim of this review was to evaluate the effect of food during the winter holidays. This knowledge will serve as a valuable foundation for the development of targeted interventions and prevention programs. (2) Methods: We conducted a systematic search of the literature via one database (PubMed). The search was limited to studies published in English in the last 10 years, with adult participants, but without specifying limits regarding the study design. We excluded articles that addressed intermittent fasting diets or weight loss intervention methods during the holidays through various diets. (3) In separate sections, we analyzed the psychological causes of gaining weight during the winter holidays, behavioral patterns, prevention strategies and the nutritional composition of the different types of food served during the festive period. Results: Using the combination of the terms "holiday and obesity", "holiday and weight gain", "festive season and obesity", and "festive season and weight gain" we obtained 216 results involving the addressed topic. Thus, only ten articles remained after screening, with a total of 4627 participants. Most participants experienced weight fluctuations during the study period, particularly during holidays. One concerning observation was that most of the weight gained during these periods was maintained even after the end of the studies, especially in those with obesity. A supervised exercise program and a controlled diet at work over the Christmas period are effective strategies for avoiding weight gain and its deleterious effects in people with metabolic syndrome or weight problems. (4) In addition, attention must be focused on the psycho-social factors during the holidays because for some people it is a stressful period and can cause a much higher caloric consumption. The simplest method to approach during the holidays is to implement small tips and tricks during this period that will prevent individuals from gaining extra pounds. Conclusions: It is essential to acknowledge that obesity is a multifaceted condition that requires a comprehensive and multidisciplinary approach to address its underlying factors and provide ongoing assistance to individuals in their weight-management endeavors. Even the most effective short-term interventions are likely to produce continued positive outcomes with persistent intervention and support.

Abstract
Understanding food prices and affordability is crucial for promoting healthy dietary habits and informing policy actions. We assessed changes in the cost and affordability of habitual and recommended healthy diets in Northwest Tasmania from 2021 to 2023. The recommended diet was 16-22% less expensive than the habitual diet during the period. Notably, 60% of the total cost of the habitual diet was spent on discretionary items. The cost of the habitual diet increased by 9% in this period, whereas the cost of the recommended diet increased by only 2%. The habitual diet was unaffordable for households with median gross, minimum wage disposable or welfare-dependent incomes. The recommended diet, however, was affordable for some groups but posed a risk of food stress for those with median gross and minimum wage disposable income and remained unaffordable for those who were welfare dependent. Our findings reveal that adhering to a healthy Australian Dietary Guidelines-recommended diet can be more cost-effective than following a habitual unhealthy diet. However, adopting a healthy diet can be challenging for low-income families. Interventions such as financial support, nutrition education, community gardens and food hubs, as well as price regulation and subsidies for farmers, can help address food insecurity in Northwest Tasmania.

Abstract
PURPOSE OF REVIEW To explore the current evidence relating to the practical management of cancer cachexia in palliative care. RECENT FINDINGS The authors found a growing evidence base including the publication of several expert guidelines since 2020. Guidelines identified the need for individualised nutritional and physical exercise support as the mainstay of cachexia management. Dietician and allied health professional referrals are recommended for the best patient outcomes. Limitations of nutritional support and exercise are acknowledged. Patient outcomes from multimodal anti-cachexia therapy are awaited at this time. Communication about the mechanisms of cachexia and nutritional counselling are identified as ways to reduce distress. Evidence supporting the use of pharmacological agents remains insufficient to make recommendations. Corticosteroids and progestins may be offered for symptom relief in refractory cachexia, taking into consideration well-documented side effects. Emphasis is placed on adequately managing nutritional impact symptoms. A specific role for palliative care clinicians and the use of existing palliative care guidelines in managing cancer cachexia were not identified. SUMMARY Current evidence recognises the inherently palliative nature of cancer cachexia management, and practical guidance correlates with the tenets of palliative care. Individualised approaches to support nutritional intake, physical exercise and alleviate symptoms that accelerate cachexia processes are currently recommended.

Adv Nutr 2023; 14:983-994. [PMID: 37419418 PMCID: PMC10509404 DOI: 10.1016/j.advnut.2023.06.009] [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: 10/01/2022] [Revised: 05/06/2023] [Accepted: 06/26/2023] [Indexed: 07/09/2023] Open
Abstract
Nearly all approaches to personalized nutrition (PN) use information such as the gene variants of individuals to deliver advice that is more beneficial than a generic "1-size-fits-all" recommendation. Despite great enthusiasm and the increased availability of commercial services, thus far, scientific studies have only revealed small to negligible effects on the efficacy and effectiveness of personalized dietary recommendations, even when using genetic or other individual information. In addition, from a public health perspective, scholars are critical of PN because it primarily targets socially privileged groups rather than the general population, thereby potentially widening health inequality. Therefore, in this perspective, we propose to extend current PN approaches by creating adaptive personalized nutrition advice systems (APNASs) that are tailored to the type and timing of personalized advice for individual needs, capacities, and receptivity in real-life food environments. These systems encompass a broadening of current PN goals (i.e., what should be achieved) to incorporate "individual goal preferences" beyond currently advocated biomedical targets (e.g., making sustainable food choices). Moreover, they cover the "personalization processes of behavior change" by providing in situ, "just-in-time" information in real-life environments (how and when to change), which accounts for individual capacities and constraints (e.g., economic resources). Finally, they are concerned with a "participatory dialog between individuals and experts" (e.g., actual or virtual dieticians, nutritionists, and advisors) when setting goals and deriving measures of adaption. Within this framework, emerging digital nutrition ecosystems enable continuous, real-time monitoring, advice, and support in food environments from exposure to consumption. We present this vision of a novel PN framework along with scenarios and arguments that describe its potential to efficiently address individual and population needs and target groups that would benefit most from its implementation.

Abstract
Omnivorous animals, including mice and humans, tend to prefer energy-dense nutrients rich in fat over plant-based diets, especially for short periods of time, but the health consequences of this short-term consumption of energy-dense nutrients are unclear. Here, we show that short-term reiterative switching to 'feast diets', mimicking our social eating behavior, breaches the potential buffering effect of the intestinal microbiota and reorganizes the immunological architecture of mucosa-associated lymphoid tissues. The first dietary switch was sufficient to induce transient mucosal immune depression and suppress systemic immunity, leading to higher susceptibility to Salmonella enterica serovar Typhimurium and Listeria monocytogenes infections. The ability to respond to antigenic challenges with a model antigen was also impaired. These observations could be explained by a reduction of CD4+ T cell metabolic fitness and cytokine production due to impaired mTOR activity in response to reduced microbial provision of fiber metabolites. Reintroducing dietary fiber rewired T cell metabolism and restored mucosal and systemic CD4+ T cell functions and immunity. Finally, dietary intervention with human volunteers confirmed the effect of short-term dietary switches on human CD4+ T cell functionality. Therefore, short-term nutritional changes cause a transient depression of mucosal and systemic immunity, creating a window of opportunity for pathogenic infection.

Abstract
The purpose of this narrative review is to emphasize the importance of food consumption and meal selection on mental health and brain function, including psychological and behavioral reactions such as mood, loving relationships, violence, and criminal activity. Additionally, by being aware of the link between food and mental health, the community can be encouraged to make informed food choices in order to avoid unfavorable outcomes like criminality. Food behaviors are shifting significantly over the world. There are also significant changes in mood, sadness, happiness, and violence, as well as the spread of the variety and severity of mental diseases that lead to violent acts. Food intake and meal selection have evolved over the last ten years as the variety and accessibility of food options have become easier and more diverse. These modifications might have both beneficial and bad consequences. This article examines the relationship between food intake and its impact on marital satisfaction. The goal of this review is to support or refute the claim that food influences mood, love, or criminal behavior, or vice versa. Various diets can have an impact on one's mental health and brain, influencing psychological reactions and behavioral responses such as mood, loving relationships, violence, and even criminal activity. Food insecurity has been demonstrated in various studies to have a negative impact on health and psychological well-being, leading to despair, loss of happiness, marital conflict, and violence. For example, herbal extracts and flavonoids have the potential to improve gut microbiota and treat mood disorders. Understanding how the gut-brain axis communicates might help guide interventions for mood and cognitive function. Since the root of most diseases and behaviors is significantly related to the type of food consumed, this research addresses this issue in order to reduce the cost of treatment and prevention of crime and delinquency at the community level by consciously choosing the food consumed by the society. In other words, prevention is always better than cure.

Abstract
AIMS The aim of this narrative review was to identify important knowledge gaps in behavioural science relating to type 2 diabetes prevention, to inform future research in the field. METHODS Seven researchers who have published behaviour science research applied to type 2 diabetes prevention independently identified several important gaps in knowledge. They met to discuss these and to generate recommendations to advance research in behavioural science of type 2 diabetes prevention. RESULTS A total of 21 overlapping recommendations for a research agenda were identified. These covered issues within the following broad categories: (a) evidencing the impact of whole population approaches to type 2 diabetes prevention, (b) understanding the utility of disease-specific approaches to type 2 diabetes prevention such as Diabetes Prevention Programmes (DPPs) compared to generic weight loss programmes, (c) identifying how best to increase reach and engagement of DPPs, whilst avoiding exacerbating inequalities, (d) the need to understand mechanism of DPPs, (e) the need to understand how to increase maintenance of changes as part of or following DPPs, (f) the need to assess the feasibility and effectiveness of alternative approaches to the typical self-regulation approaches that are most commonly used, and (g) the need to address emotional aspects of DPPs, to promote effectiveness and avoid harms. CONCLUSIONS There is a clear role for behavioural science in informing interventions to prevent people from developing type 2 diabetes, based on strong evidence of reach, effectiveness and cost-effectiveness. This review identifies key priorities for research needed to improve existing interventions.

Abstract
There is ample behavioral evidence that others' mere presence can affect any behavior in human and non-human animals, generally facilitating the expression of mastered responses while impairing the acquisition of novel ones. Much less is known about i) how the brain orchestrates the modulation of such a wide array of behaviors by others' presence and ii) when these neural underpinnings mature during development. To address these issues, fMRI data were collected in children and adults alternately observed and unobserved by a familiar peer. Subjects performed a numerosity comparison task and a phonological comparison task. While the former involves number-processing brain areas, the latter involves language-processing areas. Consistent with previous behavioral findings, adults' and children's performance improved in both tasks when observed by a peer. Across all participants, task-specific brain regions showed no reliable change in activity under peer observation. Rather, we found task-independent changes in domain-general brain regions typically involved in mentalizing, reward, and attention. Bayesian analyses singled out the attention network as the exception to the close child-adult resemblance of peer observation neural substrates. These findings suggest that i) social facilitation of some human education-related skills is primarily orchestrated by domain-general brain networks, rather than by task-selective substrates, and ii) apart from attention, peer presence neural processing is largely mature in children.

Abstract
Obesity is a chronic disease resulting from multifactorial causes mainly related to lifestyle (sedentary lifestyle, inadequate eating habits) and to other conditions such as genetic, hereditary, psychological, cultural, and ethnic factors. The weight loss process is slow and complex, and involves lifestyle changes with an emphasis on nutritional therapy, physical activity practice, psychological interventions, and pharmacological or surgical treatment. Because the management of obesity is a long-term process, it is essential that the nutritional treatment contributes to the maintenance of the individual's global health. The main diet-related causes associated with excess weight are the high consumption of ultraprocessed foods, which are high in fats, sugars, and have high energy density; increased portion sizes; and low intake of fruits, vegetables, and grains. In addition, some situations negatively interfere with the weight loss process, such as fad diets that involve the belief in superfoods, the use of teas and phytotherapics, or even the avoidance of certain food groups, as has currently been the case for foods that are sources of carbohydrates. Individuals with obesity are often exposed to fad diets and, on a recurring basis, adhere to proposals with promises of quick solutions, which are not supported by the scientific literature. The adoption of a dietary pattern combining foods such as grains, lean meats, low-fat dairy, fruits, and vegetables, associated with an energy deficit, is the nutritional treatment recommended by the main international guidelines. Moreover, an emphasis on behavioral aspects including motivational interviewing and the encouragement for the individual to develop skills will contribute to achieve and maintain a healthy weight. Therefore, this Position Statement was prepared based on the analysis of the main randomized controlled studies and meta-analyses that tested different nutrition interventions for weight loss. Topics in the frontier of knowledge such as gut microbiota, inflammation, and nutritional genomics, as well as the processes involved in weight regain, were included in this document. This Position Statement was prepared by the Nutrition Department of the Brazilian Association for the Study of Obesity and Metabolic Syndrome (ABESO), with the collaboration of dietitians from research and clinical fields with an emphasis on strategies for weight loss.

[PMID: 36921805 PMCID: PMC10196585 DOI: 10.1016/j.tjnut.2023.02.030] [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: 01/06/2023] [Revised: 02/10/2023] [Accepted: 02/23/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND Assessment of individual and population-level dietary intake is critical for public health surveillance, epidemiology, and dietary intervention research. In recognition of that need, the National Insitutes of Health (NIH) has a history of funding research projects designed to support the development, implementation, and refinement of tools to assess dietary intake in humans. OBJECTIVES This report provides data and information on NIH-funded dietary intake assessment methodological research over the period of 2012-2021. METHODS Data were extracted from an internal NIH data system using the Research, Condition, and Disease Categorization (RCDC) spending category for Nutrition. Data were then examined to identify research focused on dietary assessment tools or methods to capture or analyze dietary intake. RESULTS Over the decade of 2012-2021, NIH supported 46 grants and 2 large contracts specific to dietary assessment methods development. The top 6 Institutes and Offices funding dietary assessment methods research were identified. Most projects were limited to adults. Projects ranged from novel methods to capture dietary intake, and refinement of analytical methods, to biomarkers of dietary intake. One key contract supported the automated self-administered 24-h dietary assessment tool (ASA24), a widely used, free tool available to the research community for assessing dietary intake. CONCLUSIONS NIH's support for dietary assessment methods development over this 10-y period was small but grew over time with an expanding number and variety of methods, data sources, and technological advancements in the assessment of dietary intake. NIH remains committed to supporting research seeking to advance the field of dietary assessment methods research.

Abstract
OBJECTIVE This study examined the association between family meals and social eating behaviour with depression, anxiety and stress symptoms among Spanish adolescents. METHODS This was a cross-sectional study with data obtained from a representative sample of adolescents aged 12-17 years from Valle de Ricote, Murcia, Spain. Emotional symptomatology was evaluated with the Depression, Anxiety and Stress Scale. The frequency of family meals and social eating behaviour were self-reported. RESULTS Each additional point in social eating behaviour decreased the probability of having a higher number of depressive (OR = 0.83; 95% CI, 0.75-0.92), anxiety (OR = 0.88; 95% CI, 0.80-0.97) and stress (OR = 0.90; 95% CI, 0.82-0.99) symptoms. CONCLUSIONS Higher social eating behaviour was associated with lower probabilities of higher number of depressive, anxiety and stress symptoms.

Changes in food cue reactivity through affective and nonaffective touch: An event-related potential study. Appetite 2023; 183:106481.

Abstract
Affective touch (gentle/slow brushing of the skin) can facilitate the allocation of processing resources to simultaneously present stimuli from different modalities. The present event-related potential (ERP) study investigated whether affective touch can enhance attention to visual cues of healthy food. Female participants (n = 117) were randomly assigned to three different groups that either received affective touch, nonaffective touch (fast brushing of the skin), or no touch during the presentation of pictures of healthy food (fruits and vegetables) and non-food. Electrocortical markers of motivated attention (frontal/parietal P300, late positive potential: LPP) and reported appetite for the depicted food items were compared between the three groups. Nonaffective touch was associated with reduced amplitudes of the frontal P300/LPP (300-1000 ms) for food pictures indexing reduced motivated attention. Affective touch did not influence food cue reactivity (P300/LPP, appetite). Effects of affective touch may be restricted to specific stimuli, e.g. those with social relevance.

Abstract
Introduction China has the largest youth population in the world. To better implement the Smoke-free School Initiative, this study aims to examine the protective and risk factors for different smoking behaviors (never smoked, experimental smoking, and current smoking) among school adolescents based on social cognitive theory. Methods This research was a secondary analysis of a cross-sectional survey of middle schools in Huli District of Xiamen, China. The final sample consisted of 1937 participants with an average age of 15.41 (SD = 1.64). Descriptive statistics were used to summarize the sociodemographic characteristics of the sample. Multivariate multinomial logistic regression analysis was performed using four models. Results Of the respondents, 1685 (86.99%) were never smokers, 210 (10.84%) were experimental smokers, and 42 (2.17%) were current smokers. Social norms, positive outcome expectations, anti-smoking self-efficacy, and attitudes toward control tobacco policies were associated with adolescents' smoking behaviors. The number of smoking family members, classmates smoking, the perception that smoking is cool and attractive, and attitudes toward control tobacco policies were the predictors of current smoking behavior (p < 0.05). In contrast, friends smoking and individual and social relationship motivation were associated with only experimental smoking (p < 0.05). Discussion The relationship of social norms, positive outcome expectations, anti-smoking self-efficacy, and attitudes toward control tobacco policies varied across smoking behaviors. Family, school, society and the government need to cooperate in prevention and intervention programs for adolescent smoking. The relationships between these factors and adolescents' different smoking behaviors needs to be further verified.

Abstract
Introduction: Sugar consumption is associated with many negative health consequences. It is, therefore, important to understand what can effectively influence individuals to consume less sugar. We recently showed that a healthy eating call by a health expert can significantly decrease the willingness to pay (WTP) for sugar-containing food. Here, we investigate which aspects of neural responses to the same healthy eating call can predict the efficacy of expert persuasion.Methods: Forty-five healthy participants performed two blocks of a bidding task, in which they had to bid on sugar-containing, sugar-free and non-edible products, while their electroencephalography (EEG) was recorded. In between the two blocks, they listened to a healthy eating call by a nutritionist emphasizing the risks of sugar consumption.Results: We found that after listening to the healthy eating call, participants significantly decreased their WTP for sugar-containing products. Moreover, a higher intersubject correlation of EEG (a measure of engagement) during listening to the healthy eating call resulted in a larger decrease in WTP for sugar-containing food. Whether or not a participant’s valuation of a product was highly influenced by the healthy eating call could also be predicted by spatiotemporal patterns of EEG responses to the healthy eating call, using a machine learning classification model. Finally, the healthy eating call increased the amplitude of the P300 component of the visual event-related potential in response to sugar-containing food.Disussion: Overall, our results shed light on the neural basis of expert persuasion and demonstrate that EEG is a powerful tool to design and assess health-related advertisements before they are released to the public.

Abstract
Young adults are frequently confronted with eating-related social media content. How such exposure influences eating in those who post and their network members is largely unknown. We conducted two intensive longitudinal field experiments combining self-reports with social media data. The posting behavior of young adults was manipulated. We examined how postings about fruit and vegetables affected intake in senders and their network members (Study 1, N = 81) and in senders with a change goal (Study 2, N = 128). Potential mechanisms of action were explored. Descriptively, posting led to a stronger increase of senders' and network members' intake, but this increase was not statistically significant. Posting led to higher perceived social support and injunctive norms of senders (Study 1). Posting supported eating behavior change; the effect size was comparable to picture-based self-monitoring of intake (Study 2). Intraindividual variations in senders' daily eating-related social media activities were associated with daily eating behavior and perceived social support (both studies), daily self-efficacy, experiential and instrumental attitudes, and goal commitment (Study 2). Our studies underline that social media environments should be considered in research and interventions targeting eating behavior of young adults.

Abstract
Childhood obesity is a precursor to future health complications. In adults, neighborhood walkability is inversely associated with obesity prevalence. Recently, it has been shown that current urban walkability has been influenced by historical discriminatory neighborhood disinvestment. However, the relationship between this systemic racism and obesity has not been extensively studied. The objective of this study was to evaluate the association of neighborhood walkability and redlining, a historical practice of denying home loans to communities of color, with childhood obesity. We evaluated neighborhood walkability and walkable destinations for 250 participants of the Healthy Start cohort, based in the Denver metropolitan region. Eligible participants attended an examination between ages 4 and 8. Walkable destinations and redlining geolocations were determined based on residential addresses, and a weighting system for destination types was developed. Sidewalks and trails in Denver were included in the network analyst tool in ArcMap to calculate the precise walkable environment for each child. We implemented linear regression models to estimate associations between neighborhood characteristics and child body mass index (BMI) z-scores and fat mass percent. There was a significant association between child BMI and redlining (β: 1.36, 95% CI: 0.106, 2.620). We did not find an association between walkability measures and childhood obesity outcomes. We propose that cities such as Denver pursue built environment policies, such as inclusionary zoning and direct investments in neighborhoods that have been historically neglected, to reduce the childhood health impacts of segregated poverty, and suggest further studies on the influences that redlining and urban built environment factors have on childhood obesity.

Abstract
Epidemiological and intervention studies in nutritional psychiatry suggest that the risk of mood disorders is associated with what we eat. However, few studies use a person-centred approach to explore the food and mood relationship. In this qualitative study of 50 Australian participants, we explored individuals' experiences with food and mood as revealed during focus group discussions. Using a thematic template analysis, we identified three themes in the food and mood relationship: (i) social context: familial and cultural influences of food and mood, (ii) social economics: time, finance, and food security, and (iii) food nostalgia: unlocking memories that impact mood. Participants suggested that nutrients, food components or food patterns may not be the only way that food impacts mood. Rather, they described the social context of who, with, and where food is eaten, and that time, finances, and access to healthy fresh foods and bittersweet memories of foods shared with loved ones all impacted their mood. Findings suggest that quantitative studies examining the links between diet and mood should look beyond nutritional factors and give increased attention to the cultural, social, economic, and identity aspects of diet.

Abstract
AIMS To investigate whether 'low sugar' and related claims influence consumers' perceptions of the healthiness or other attributes of alcoholic drinks, promote greater consumption or impact diet and activity behaviour intentions. METHOD N = 501 Australian women aged 18-35 viewed and rated six images of alcoholic drinks in a randomized online experiment with a 2 (claim: low sugar claim, no claim control) × 2 (drink type: cider, ready-to-drink spirits) between-subjects design. RESULTS Participants who viewed drinks with low sugar claims rated them as healthier, less harmful to health, lower in sugar and kilojoules, and more suitable for weight management and a healthy diet than participants who viewed identical drinks with no claim (P < 0.001-P = 0.002). Drinks with low sugar claims were also perceived as being lower in alcohol (P < 0.001) despite being of equivalent alcohol content. There were no significant differences in anticipated social approval associated with consumption or in hypothetical intended consumption of the drinks, but participants who viewed drinks with low sugar claims were less likely to indicate they would compensate for consumption of the drink by modifying food intake or physical activity (P = 0.01). CONCLUSIONS Low sugar and related claims on alcoholic drinks can generate a health halo: consumers generalise from a specific favourable attribute (low sugar) to misperceive other favourable health- and nutrition-related attributes, including lower alcohol content. Findings support calls to reconsider the permissibility of low sugar claims on alcoholic drinks as they may mislead consumers.

Abstract
Black Americans have the lowest life expectancy and health-related quality of life (HRQoL; a strong predictor of premature mortality) of any racial/ethnic group in the United States. Low rates of physical activity and engagement in healthy eating are two known contributors to low HRQoL. Black Americans are more likely to live in environments that inhibit engagement in these two contributors. The present study examined sense of community as a buffer against the adverse effects of low physical activity and healthy eating on HRQoL among Black Americans. A sample of 290 Black American adults were recruited for the present study. Results indicate that sense of community buffers against the adverse effects of low physical activity on HRQoL. The results of the present study can be used by health promotion interventionists and policy-makers to improve HRQoL and reduce premature mortality among Black Americans.

Understanding the determinants of food provisioning is crucial for efforts to reduce household food wastage. Various studies have identified a web of interrelated socio-demographic characteristics, values, attitudes, and skills as drivers of household food wastage. Our contribution is in exploring the relationship between cultural and religious views and food waste generation. We do that in the context of three social groups in Israel: secular Jews, religious Jews, and Muslim Arabs. We interviewed 27 individuals who have a certain standing in their respective communities with broad perspective of the cultural context of food-related issues. Our results highlight the conflict between religious and secular values and actual food wastage practices. We identified several factors that lead to household food wastage: past scarcity, the consumer culture, and hospitality. We found various ways by which cultural and religious values shape food-waste perceptions. Results show a dissonance between food-related motivations and actual practices. We also demonstrate how the dissonance can be reconciled, both on the level of justification and on the level of action.

BMC Public Health 2022; 22:2390. [PMID: 36539744 PMCID: PMC9763797 DOI: 10.1186/s12889-022-14729-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 11/25/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Diet norms are the shared social behaviours and beliefs about diets. In many societies, including the UK, these norms are typically linked to unhealthy diets and impede efforts to improve food choices. Social interactions that could influence one another's food choices, were highly disrupted during the lockdowns in response to the COVID-19 pandemic. A return to workplaces and re-establishment of eating networks may present an opportunity to influence dietary norms by introducing minimum dietary standards to in workplaces, which could then spread through wider home and workplace networks. METHODS An agent-based model was constructed to simulate a society reflecting the structure of a city population (1000 households) to explore changes in personal and social diet-related norms. The model tracked individual meal choices as agents interact in home, work or school settings and recorded changes in diet quality (range 1 to 100). Scenarios were run to compare individuals' diet quality with the introduction of minimum dietary standards with degrees of working from home. RESULTS The more people mixed at work the greater the impact of minimum standards on improving diet norms. Socially isolated households remained unaffected by minimum standards, whereas household members exposed directly, in workplaces or schools, or indirectly, influenced by others in the household, had a large and linear increase in diet quality in relation to minimum standards (0.48 [95% CI 0.34, 0.62] per unit increase in minimum standards). Since individuals regressed to the new population mean, a small proportion of diets decreased toward lower population norms. The degree of return to work influenced the rate and magnitude of change cross the population (-2.4 points [-2.40, -2.34] in mean diet quality per 20% of workers isolating). CONCLUSIONS These model results illustrate the qualitative impact social connectivity could have on changing diets through interventions. Norms can be changed more in a more connected population, and social interactions spread norms between contexts and amplified the influence of, for example, workplace minimum standards beyond those directly exposed. However, implementation of minimum standards in a single type of setting would not reach the whole population and in some cases may decrease diet quality. Any non-zero standard could yield improvements beyond the immediate adult workforce and this could spill between social contexts, but would be contingent on population connectivity.

Association between Fathers' and Mothers' Parenting Styles and the Risk of Overweight/Obesity among Adolescents in San José Province, Costa Rica. Nutrients 2022; 14:nu14245328. [PMID: 36558486 PMCID: PMC9781581 DOI: 10.3390/nu14245328] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
Parenting styles are a risk factor for adolescents overweight/obesity worldwide, but this association is not well understood in the context of Latin America. This study examines the association between the parenting styles of mothers and fathers and the risk of overweight/obesity among Costa Rican adolescents. Data are cross-sectional from a sample of adolescents (13-18 years old) enrolled in ten urban and eight rural schools (n = 18) in the province of San José, Costa Rica, in 2017. Hierarchical logistic regression analyses were performed to assess the likelihood of adolescents being overweight according to the mothers' and fathers' parenting styles. A significant association was found between the risk of adolescent overweight/obesity and the paternal authoritarian style only in rural areas (B = 0.622, SE = 0.317, Wald = 3.864, ExpB = 1.863, p = 0.04), and between said risk and the paternal permissive style only in male adolescents (B = 0.901, SE = 0.435, Wald = 4.286, ExpB = 2.461, p = 0.038). For maternal parenting styles, no associations reached significant levels once logistic regression models were adjusted for the fathers' parenting styles. These findings underscore the importance of further studying the role of fathers' paternal parenting styles on Latin American adolescent weight outcomes. Expanding our understanding of the parenting styles of fathers has important implications for the design and implementation of culturally- and gender-appropriate family interventions.

Eating Patterns among Emergency Medical Service Providers in the United States: A Qualitative Interview Study. Nutrients 2022; 14:nu14224884. [PMID: 36432571 PMCID: PMC9696925 DOI: 10.3390/nu14224884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 11/15/2022] [Accepted: 11/16/2022] [Indexed: 11/22/2022] Open
Abstract
Emergency medical service (EMS) providers experience demanding work conditions in addition to shift work, which increases risk for nutrition related chronic disease such as metabolic syndrome, diabetes, obesity, and cardiovascular disease. The high stress, emergent, and unpredictable nature of EMS may interfere with healthy eating patterns on and off shift, however little is known about how these conditions impact dietary patterns among EMS providers. This study aimed to understand factors impacting dietary patterns through semi-structured interviews with 40 EMS providers throughout the United States. Interviews were conducted virtually via Zoom video conference. Inductive coding was used to identify themes throughout the interviews. Salient factors mentioned in the interviews included hunger, fatigue, stress, coworker influence, ambulance posting, geographical location, agency policy, and culture. Factors were grouped into 4 domains: physiological factors, psychosocial factors, physical environment, and organizational environment, represented by an adapted version of the social ecological model of health behaviors to include factors influencing eating patterns specific to EMS, which may contribute to overall health. Various barriers to healthy eating exist within EMS, and future studies should explore interventions at each level of our proposed model to improve conditions and reduce nutrition related disease risk in this essential population.

Abstract
OBJECTIVE To explore communities' perspectives on the factors in the social food environment that influence dietary behaviours in African cities. DESIGN A qualitative study using participatory photography (Photovoice). Participants took and discussed photographs representing factors in the social food environment that influence their dietary behaviours. Follow-up in-depth interviews allowed participants to tell the 'stories' of their photographs. Thematic analysis was conducted, using data-driven and theory-driven (based on the socio-ecological model) approaches. SETTING Three low-income areas of Nairobi (n 48) in Kenya and Accra (n 62) and Ho (n 32) in Ghana. PARTICIPANTS Adolescents and adults, male and female aged ≥13 years. RESULTS The 'people' who were most commonly reported as influencers of dietary behaviours within the social food environment included family members, friends, health workers and food vendors. They mainly influenced food purchase, preparation and consumption, through (1) considerations for family members' food preferences, (2) considerations for family members' health and nutrition needs, (3) social support by family and friends, (4) provision of nutritional advice and modelling food behaviour by parents and health professionals, (5) food vendors' services and social qualities. CONCLUSIONS The family presents an opportunity for promoting healthy dietary behaviours among family members. Peer groups could be harnessed to promote healthy dietary behaviours among adolescents and youth. Empowering food vendors to provide healthier and safer food options could enhance healthier food sourcing, purchasing and consumption in African low-income urban communities.

Abstract
Previous research has documented the influence of eating together on people's food expectations and choices. We conducted an fMRI study to investigate the influence of the label "eating together" on behavioral and brain responses to healthy or unhealthy foods. The participants (N = 28, 13 females; mean age = 21.19) viewed food photos presented with a label of "eating together" or "eating alone" and estimated the palatability, pleasantness, and desirability of each food. The label "eating together" elicited more positive ratings for both healthy and unhealthy foods than the label "eating alone," and this effect of social context was larger for unhealthy than healthy foods. The label "eating together" also elicited greater activation in the left insula and the right posterior insula for unhealthy foods (p = 0.001 and p = 0.004, whole-brain corrected, respectively). These findings suggest that a label of "eating together" can enhance the reward values of foods, with a potentially greater enhancement for unhealthy foods.

Abstract
Diet quality is influenced by demographics and can change over time. This study aimed to (1) compare diet quality among adolescents/adults who completed the online Healthy Eating Quiz (HEQ) by demographic characteristics, and (2) to evaluate change in score over time for repeat completers. HEQ data collected between July 2016 and May 2022 were analysed, including demographics (age, gender, vegetarian status, socio-economic status, number of people main meals are shared with, country), and diet quality calculated using the Australian Recommended Food Score (ARFS) (range 0−73) for respondents aged ≥ 16 years. Differences in ARFS by demographic characteristics and change in score over time, adjusted for age, gender and vegetarian status, were tested by linear regression. The participants (n = 176,075) were predominantly female (70.4%), Australian (62.8%), and aged 18−24 years (27.7%), with 4.0% (n = 7087) repeat completers. Mean ± SD ARFS was 33.9 ± 9.4/73. Results indicate that ARFS was significantly lower among males and significantly higher with increasing age group, higher socio-economic status, in vegetarians, those who shared main meals with others, and those living in Australia (p-values < 0.001). Mean change in ARFS over time (2.3 ± 6.9) was significantly higher for those with lower baseline scores (p < 0.001). Publicly available, brief dietary assessment tools have the potential to improve diet quality at the population level.

Abstract
CONTEXT Portion size norm is described as the perception of how much of a given food people choose to eat. Reducing the portion size norm of foods that are high in saturated fat, added sugar, and added salt toward smaller sizes might be a potential strategy to promote appropriate portion size selections. However, an overview of existing portion size norms for discretionary foods has yet to be established. OBJECTIVE The aim of this systematic review was to examine the portion size norm of discretionary foods and assess the methodologies used to investigate the norm. DATA SOURCES The literature search was conducted in 6 databases following the PRISMA guidelines (from inception to January 2022). DATA EXTRACTION Forty studies were eligible and grouped into 3 categories by portion size norm measures: normal (n = 26), appropriate (n = 8), and preferred portion sizes (n = 3). Study quality was assessed using the Joanna Briggs Institute Critical Appraisal Tools. DATA ANALYSIS A wide range of portion sizes were considered normal for each food type, with means/medians varying from 2- to 4-fold among studies. Studies differed considerably in design, with variables including the setting, food type, food presentation, the manner in which portion-size-related questions were formulated, and the range and number of displayed serving size options. The quality of reviewed studies was mixed (25 studies had low or moderate risk of bias, 15 had high risk of bias), and the method of assessing portion size was not validated in 15 of 33 quantitative studies. CONCLUSION The assessment of portion size in future studies should be conducted using tools that are validated for the population of interest so that more definitive conclusions can be drawn regarding portion size norms for discretionary foods.

Abstract
The relation among the various causal factors of obesity is not well understood, and there remains a lack of viable data to advance integrated, systems models of its etiology. The collection of big data has begun to allow the exploration of causal associations between behavior, built environment, and obesity-relevant health outcomes. Here, the traditional epidemiologic and emerging big data approaches used in obesity research are compared, describing the research questions, needs, and outcomes of 3 broad research domains: eating behavior, social food environments, and the built environment. Taking tangible steps at the intersection of these domains, the recent European Union project "BigO: Big data against childhood obesity" used a mobile health tool to link objective measurements of health, physical activity, and the built environment. BigO provided learning on the limitations of big data, such as privacy concerns, study sampling, and the balancing of epidemiologic domain expertise with the required technical expertise. Adopting big data approaches will facilitate the exploitation of data concerning obesity-relevant behaviors of a greater variety, which are also processed at speed, facilitated by mobile-based data collection and monitoring systems, citizen science, and artificial intelligence. These approaches will allow the field to expand from causal inference to more complex, systems-level predictive models, stimulating ambitious and effective policy interventions.

Abstract
Recent studies have revealed types of eating nudges that can steer consumers toward choosing healthier options. However, most of the previously studied interventions target individual decisions and are not directed to changing consumers’ underlying perception of unhealthy food. Here, we investigate how a healthy eating call—first-person narrative by a health expert—affects individuals’ willingness to pay (WTP) for sugar-free and sugar-containing food products. Participants performed two blocks of a bidding task, in which they had to bid on sweets labeled either as “sugar- free” or as “sugar-containing.” In-between the two blocks, half of the participants listened to a narrative by a dietary specialist emphasizing the health risks of sugar consumption, whereas the remaining participants listened to a control narrative irrelevant to food choices. We demonstrate that the health expert’s narrative decreased individuals’ WTP for sugar-containing food, but did not modulate their WTP for sugar- free food. Overall, our findings confirm that consumers may conform to healthy eating calls by rather devaluating unhealthy food products than by increasing the value of healthy ones. This paves the way for an avenue of innovative marketing strategies to support individuals in their food choices.

[PMID: 35569603 DOI: 10.1016/j.appet.2022.106081] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 04/07/2022] [Accepted: 05/09/2022] [Indexed: 11/02/2022]
Abstract
This qualitative study, framed by social identity theory, examines how self-identified vegans and vegetarians negotiate diet-related social norm conflicts within their social networks. Twenty-one semi-structured interviews with 18- to 58-year-old vegans and vegetarians who represented five nationalities were analysed inductively through thematic analysis. According to the results, social norm conflicts occurred in contexts where tense family relations or boundaries between in-group and out-group were salient. The results also show that in order to manage norm conflict situations, the interviewees used strategies towards the dominant social norms, such as adapting, challenging, and weakening. In particular, adapting to the dominant social norms was used in relationships that were not close, whereas challenging and weakening were used within close relationships. The interviewees had developed practical solutions to resolve social norm conflicts, such as eating what was served, actively providing information, or acting as an example to others. The results enhance understanding of the challenges entailed by practising vegan or vegetarian diet in an omnivorous society.
