PLoS One 2024; 19:e0308689. [PMID: 39137220 PMCID: PMC11321581 DOI: 10.1371/journal.pone.0308689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 07/29/2024] [Indexed: 08/15/2024] Open
Abstract
BACKGROUND AND AIM The long-term impact of COVID-19 on nutrition and community health is inevitably noticeable. These effects can change the nutritional behavior and lifestyle of survivors. Due to the COVID consequential fear and anxiety, the pandemic can alter the motivations for choosing, buying, and consuming food. The relationship between nutritional behavior and COVID-19 fear is the primary purpose of this research. MATERIALS & METHODS This cross-sectional study was conducted via online and face-to-face surveys. Accessing participants was through health centers of Qazvin, Iran, and the selected centers were sampled by cluster sampling method. The study population included 331 adults aged 18 to 65. Data were collected in three sections using valid questionnaires. The Demographic Questionnaire, FCV-19S, and FCQ were used to gather demographic information, the level of fear caused by COVID-19, and food choice motivations, respectively. The statistical analyzes were performed using R software. Analysis of variance and linear regression methods were used to determine the effect of independent variables on dependent variables (p = 0.05). RESULTS The mean score of fear of COVID-19 in the study population was 15.25 ± 5.78. Price, Mood, Natural content, Familiarity, Convenience, and Ethical concerns were significantly and positively associated with fear of COVID-19 (p<0.05). The only food motive significantly different than before during COVID-19 was Health, which was increased (p = 0.02). Sensory appeal and Health were the most important motivations for food choices before and during COVID-19. The Ethical concern was considered the least important food motivation. DISCUSSION AND CONCLUSION Some food motivations were associated with fear of COVID-19, possibly due to their psychological nature. The increasing importance of the Health factor and Natural content motivations can relate to the advice of experts on the importance of eating healthy food to counteract COVID-19 and indicate people's preference for this training.

Abstract
There is a growing concern about unhealthy eating habits and their impact on public health, underscoring the importance of research to understand its determinants and encourage healthy food habits. Using behavioural economic insights in researching dietary habit offer advantages beyond the scope of observational studies. Therefore, this paper examines impulsivity, self-indulgence, prudence and their associations with an individual's eating habits and body mass index (BMI). Data were collected from a sample of 487 Chinese participants. Most participants (88%) had good eating habits based on the Healthy Eating Assessment score. The findings of a logistic regression analysis investigating the determinants of individual dietary behaviour based on participants' self-rating of their overall dietary habits indicate that consumers who showed temporal impulsivity for favourite food tend to have poorer habits of eating healthy foods. The results of a multiple linear regression examining the factors that influence eating habits from a composite score of the Healthy Eating Assessment indicate that the score is better with temporal impulsivity for healthy food and poor with temporal impulsivity for unhealthy food. Further, the score decreases with impulsivity measured as low self-control. The control variables, age and gender, are also significant. The findings of a linear regression analysis exploring the determinants of BMI and their association with impulsivity, self-indulgence and prudence indicate that individuals with higher impulsivity measured as low self-control are mostly in the higher BMI category. These findings are important for designing and implementing public health initiatives to promote healthier dietary habits.

Abstract
Since the start of the war in Ukraine, almost 8 million people left the country; more than 1 million of them relocated to Germany. It is to be expected that the war puts considerable strain on refugees, which will impact the public health system in host countries. This paper presents baseline data and protocol of longitudinal online experimental study of 619 Ukrainian refugees in Germany started in autumn 2022, focusing on participants' self-reports of appetite, food intake, and levels of stress, anxiety, and depressive symptoms to examine their associations. Results indicate that levels of stress, anxiety, and depressive symptoms in refugees significantly exceed the indicators of relevant parameters as reported by independent large-scale surveys conducted in Ukraine before the war as well as strong correlations between these deviations (.59 ≤ r ≤ .69, p = .005). Changes in appetite were related to more severe psycho-emotional deviations (.15 ≤ r ≤ .19, p = .003) and somewhat unhealthier food intake (r = -.08, p < .001). The study underlines the need of psychological care for refugees to improve their mental health and counteract potential negative consequences for physical health via changes in food intake, for which suitable interventions need to be developed.

Abstract
In 2022 the British government made calorie labels on menus a legal requirement to encourage healthier food choices while dining out. Yet, little research has explored perceptions of calorie labels on menus in the United Kingdom or tested whether there may be groups of people vulnerable to potential negative effects of calorie labels, such as those with body dissatisfaction. This between-subjects, convergent mixed-methods study addressed these enquiries. Participants were 562 adults who completed an online survey where hypothetical food orders were made from a menu. The study found that participants who viewed a menu with calorie labels ordered fewer calories. Quantitative results did not find that participants with higher levels of body dissatisfaction were at significantly greater odds of using calorie labels to order fewer calories. However, our qualitative (thematic) analysis revealed that experiences of calorie labels could be shaped by body image concerns. Themes further drew on how calorie labels were empowering, but there were also concerns about their oversimplicity. Findings are discussed in relation to implications for future calorie labelling policies. Given the inconsistent findings amongst the limited amount of literature investigating the role of body dissatisfaction in how calorie labels are used, future research is crucial. In the meantime, as a cautionary measure, clinicians involved in supporting individuals with body or food-related concerns should be aware of the challenges their clients may experience in facing calorie labels on menus when dining out.

Abstract
Diet and physical activity guidelines for cancer survivorship are less likely to be followed by populations of minority cancer survivors, such as Latina/Hispanic women, compared to non-Hispanic White women. It is important to understand psychosocial mechanisms that may increase adherence to healthy lifestyle habits, especially in populations at risk for poorer cancer outcomes. This cross-sectional study examined the relationships between overall social support (SS) and SS from three sources (family, friends, and significant other) with diet (fruit and vegetables, fat, energy density, and diet quality), and moderate-to-vigorous physical activity (MVPA) behaviors in Latina/Hispanic women with a history of breast cancer (n = 85; M age = 55.2; SD = 9.2). Linear regression models and odds ratios were used to examine associations and adjusted for age, income, and acculturation. Family, significant other, and total SS were positively related to total fruit and vegetable intake but SS from friends was not. Higher levels of SS from all sources were each related to a low energy density diet. A higher quality diet was only related to SS from family. SS was not related to fat intake or MVPA. Higher SS from family and a significant other were associated with higher odds of meeting the fruit/vegetable guidelines; (family, OR = 3.72, 95% CI [1.21, 11.39]; significant other, OR = 3.32, 95% CI [1.08, 10.30]). Having more SS from family or a significant other may contribute to Latina/Hispanic women breast cancer survivors meeting national guidelines for a diet high in fruits and vegetables and low in energy density.

Abstract
Objectives We introduce the Bitemporal Lens Model, a comprehensive methodology for chronic disease prevention using digital biomarkers. Materials and Methods The Bitemporal Lens Model integrates the change-point model, focusing on critical disease-specific parameters, and the recurrent-pattern model, emphasizing lifestyle and behavioral patterns, for early risk identification. Results By incorporating both the change-point and recurrent-pattern models, the Bitemporal Lens Model offers a comprehensive approach to preventive healthcare, enabling a more nuanced understanding of individual health trajectories, demonstrated through its application in cardiovascular disease prevention. Discussion We explore the benefits of the Bitemporal Lens Model, highlighting its capacity for personalized risk assessment through the integration of two distinct lenses. We also acknowledge challenges associated with handling intricate data across dual temporal dimensions, maintaining data integrity, and addressing ethical concerns pertaining to privacy and data protection. Conclusion The Bitemporal Lens Model presents a novel approach to enhancing preventive healthcare effectiveness.

Abstract
BACKGROUND There is evidence that most people are aware of the importance of healthy eating and have a broad understanding regarding types of food that enhance or detract from health. However, greater health literacy does not always result in healthier eating. Andreasen's Social Marketing Model and Community-Based Social Marketing both posit that, in order to change health behaviours, it is crucial to understand reasons for current behaviours and perceived barriers and benefits to improved behaviours. Limited research has been conducted, however, that explores these issues with general populations. This study aimed to help address this gap in the evidence using a qualitative methodology. METHODS Three group discussions were conducted with a total of 23 participants: (1) young women aged 18-24 with no children; (2) women aged 35-45 with primary school aged children; and (3) men aged 35-50 living with a partner and with pre- or primary school aged children. The discussions took place in a regional centre of Victoria, Australia. Transcriptions were thematically analysed using an inductive descriptive approach and with reference to a recent integrated framework of food choice that identified five key interrelated determinants: food- internal factors; food- external factors; personal-state factors; cognitive factors; and sociocultural factors. RESULTS We found that food choice was complex, with all five determinants evident from the discussions. However, the "Social environment" sub-category of "Food-external factors", which included family, work, and social structures, and expectations (or perceived expectations) of family members, colleagues, friends, and others, was particularly prominent. Knowledge that one should practice healthy eating, which falls under the "Cognitive factor" category, while seen as an aspiration by most participants, was often viewed as unrealistic, trumped by the need and/or desire for convenience, a combination of Food-external factor: Social environment and Personal-state factor: Psychological components. CONCLUSIONS We found that decisions regarding what, when, and how much to eat are seen as heavily influenced by factors outside the control of the individual. It appears, therefore, that a key to improving people's eating behaviours is to make it easy to eat more healthfully, or at least not much harder than eating poorly.

Abstract
Previous research on health information seeking has primarily focused on individuals'intentions to seek or avoid information. However, limited empirical evidence exists regarding the actual behavioral patterns of information-seeking and non-seeking. To address this, we conducted a survey experiment manipulating cognitive load with mostly Belgian participants (N = 359). By integrating self-report and behavioral data, we investigated motivations and conditions associated with information (non)-seeking behaviors on a healthy diet. Guided by the risk information seeking and processing (RISP) model, we examined the roles of informational subjective norms and information insufficiency, as well as the moderating role of cognitive capacity. Neither informational subjective norms nor information insufficiency significantly correlated with information-seeking behaviors. However, a significant interaction between the predictors and cognitive capacity in predicting non-seeking behaviors was observed. These findings underscore the intricate nature of individuals' behavioral patterns in seeking or not seeking information about healthy eating.

Abstract
BACKGROUND Recent evidence highlights the importance of interventions tackling physical inactivity and unhealthy eating in lower-income countries. The purpose of this study was to examine the effectiveness of the Canadian ACCELERATION lifestyle program adapted to Brazilians. The main outcomes of the study were changes in the engagement in weekly moderate-to-vigorous physical activity (MVPA) and in the daily consumption of fruits/vegetables. METHODS The adapted intervention consisted of a 12-week quasi-randomized controlled trial delivered through email. The data from the original Canadian experimental group (CE, n = 194) and the two groups of Portuguese-speaking Brazilians living in Canada in the adapted program - Brazilian experimental (BE, n = 41) and Brazilian control (BC, n = 35) - were assessed at baseline and post-intervention. The data of the 270 participants were analyzed using two-way repeated measures factorial ANCOVA (group x time) for ratio variables and Chi-square and McNemar tests for the categorical variables. RESULTS The BE group had a significant increase in MVPA (mean difference, 95% CI: 86.3, 38.1-134.4 min/week) and fruits/vegetables intake (3.2, 1.4-5.1 servings/day) after the intervention (both p < 0.001). The proportion of participants engaging in ≥ 150 min of MVPA increased from 4.9% to 73.2%, while adoption of a healthy diet increased from 4.9% to 53.7% in the BE group (both p < 0.001). The CE group also improved on these variables (p < 0.05) with no difference vs the BE group (p > 0.05), whereas BC did not show changes (p > 0.05). CONCLUSION The Brazilian version of the ACCELERATION program effectively promoted positive health behavior changes in its participants and has the potential to contribute to the fight against risk factors for chronic diseases in Brazilians.

Abstract
This study determined consumers' attitudes towards physical and mental wellness related to red meat consumption and their willingness to pay (WTP) more for the meat. In 2019, two online surveys of red meat eaters were conducted in the USA (n = 1000) and Australia (n = 523) using commercial platforms. Results showed that over 90% of respondents indicated interest in purchasing red meat to improve their wellness status. Additionally, about 85% indicated their WTP more for red meat for its wellness benefits, with Americans indicating stronger willingness than Australian respondents. The potential of meat consumption to improve overall wellness among red meat eaters was a dominant factor influencing consumers' WTP more. Other factors that increased WTP included frequency of meat consumption, physical exercise, sleep quality, number of children in a household, partnership status, and economic position. Outcomes from this study highlight a unique opportunity for the meat industry to position meat on its qualities that include wellness improvement if backed up with robust scientific evidence.

Abstract
Dietary intake is tightly coupled to gut microbiota composition, human metabolism, and to the incidence of virtually all major chronic diseases. Dietary and nutrient intake are usually quantified using dietary questionnaires, which tend to focus on broad food categories, suffer from self-reporting biases, and require strong compliance from study participants. Here, we present MEDI (Metagenomic Estimation of Dietary Intake): a method for quantifying dietary intake using food-derived DNA in stool metagenomes. We show that food items can be accurately detected in metagenomic shotgun sequencing data, even when present at low abundances (>10 reads). Furthermore, we show how dietary intake, in terms of DNA abundance from specific organisms, can be converted into a detailed metabolic representation of nutrient intake. MEDI could identify the onset of solid food consumption in infants and it accurately predicted food questionnaire responses in an adult population. Additionally, we were able to identify specific dietary features associated with metabolic syndrome in a large clinical cohort, providing a proof-of-concept for detailed quantification of individual-specific dietary patterns without the need for questionnaires.

Abstract
Concepts and definitions of 'healthy' have been evolving within clinical treatment algorithms as well as reference standards such as Body Mass Index and Dietary Reference Intakes. Consumers' perception of the word 'healthy' is also changing to reflect longer life span, need to stay active and in a good state of mental well-being while managing multiple diseases. Guidelines from the US Food and Drug Administration indicate that substantiating evidence for support of Structure/Function (S/F) claims for dietary supplements is best derived from clinical research conducted in a 'healthy' population. S/F claims cannot be represented to diagnose, treat, cure or prevent any disease. However, in this context, the term 'healthy' is non-descriptive and largely interpreted as an absence of disease. Guidelines for treatment of disease have been broadened to include biomarkers of disease risk such that the pool of 'healthy' volunteers eligible to be enrolled in clinical trials for S/F claim substantiation is greatly diminished. This perspective presents the challenges faced by the food and dietary supplement industry and by researcher efforts designed to substantiate S/F claims and suggest the phrase 'physiologically stable' or 'apparently healthy' as descriptions better suited to replace the term 'healthy.'

van der Merwe D, de Beer H, Ellis S, Bester P, Marais F, Steyn A. Consumer objective and subjective knowledge about healthy foods: An approach to promote healthy lifestyle choices in South Africa. PLoS One 2024; 19:e0296504. [PMID: 38271393 PMCID: PMC10810447 DOI: 10.1371/journal.pone.0296504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 12/14/2023] [Indexed: 01/27/2024] Open
Abstract
Unhealthy food choices and consumption, coupled with sedentary lifestyles among consumers, intensify public health concerns regarding the quadruple disease burden, despite Primary Health Care (PHC) policy. However, the current relationship between consumer knowledge about healthy foods and following a healthy lifestyle needs to be explored. Our study, therefore, aimed to determine the association between consumers' subjective and objective knowledge about healthy foods and various healthy lifestyle choices. A cross-sectional survey was conducted among employed consumers (N = 157) from South African corporate settings. We used structural equation modelling (SEM) to determine associations between subjective and objective knowledge about healthy foods and healthy lifestyle choices. Our findings showed that most participants scored high on making healthy lifestyle choices relating to avoiding smoking (69.5%) and limiting drinking alcohol (68.7%) but less so for food and sleep (44.4%) while neglecting exercise, relaxation (13.7%), and choices that require dedicated effort (25.2%). On average, participants had high levels of subjective (mean = 3.59; 5-point Likert scale) knowledge and objective knowledge about healthy foods (88.4-95.9% correct responses). However, their objective knowledge about weight and cholesterol had severe deficiencies (36.7%). SEM confirmed an association between subjective knowledge and most healthy lifestyle choice categories, while income contributed to dedicated effort lifestyle choices. By contrast, objective knowledge did not associate with such choices. Our structural model suggests that subjective knowledge about healthy foods contributes to healthy lifestyle choices. Therefore, subjective knowledge and the objective knowledge deficiencies we identified among corporate consumers can serve as a valuable starting point for informed education to promote PHC policy and healthy lifestyle choices.

Impact of Medical School on the Relationship between Nutritional Knowledge and Sleep Quality-A Longitudinal Study of Students at Wroclaw Medical University in Poland. Nutrients 2024; 16:278. [PMID: 38257170 PMCID: PMC10819250 DOI: 10.3390/nu16020278] [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: 12/20/2023] [Revised: 01/13/2024] [Accepted: 01/16/2024] [Indexed: 01/24/2024] Open
Abstract
The aim of this study was to investigate the impact of the first year of medical school on the relationship between nutritional knowledge and sleep. To achieve this, first-year medical students at Wroclaw Medical University were invited to participate in the study during both the initial and final months of their first academic year. The study included 570 students in the initial period and 705 in the latter. The research questionnaire comprised the KomPAN, assessing nutritional knowledge, and the Pittsburgh Sleep Quality Index (PSQI), evaluating sleep quality. The majority of students demonstrated at least sufficient nutritional knowledge, while approximately two-thirds of students experienced poor sleep in both periods. Notably, sleep quality further deteriorated in the second period (PSQI total score: 6.86 vs. 7.38, p = 0.0157). This change was influenced mainly by a decrease in sleep duration and an increase in the use of sleep medications (both p < 0.0001). The significant difference in overall sleep quality between different nutritional knowledge levels emerged only in the second semester, where students with the highest nutritional knowledge slept the best, while those with the lowest slept the worst (p = 0.0001). Crucially, in both periods, the use of sleep medications was highest among individuals with insufficient nutritional knowledge. Throughout the academic year, the usage increased for all except those with the highest nutritional knowledge, who exhibited the best sleep (p < 0.0001). The escalating use of sleep medications among medical students warrants greater attention, and leveraging the relationship between nutritional knowledge and sleep could prove beneficial, as positive habits in one domain may positively influence the other.

The specially designed nudging tableware promotes healthy food choices: Evidence from a randomized crossover trial in normal-weight young adults. Physiol Behav 2024; 273:114412. [PMID: 37981095 DOI: 10.1016/j.physbeh.2023.114412] [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: 08/06/2023] [Revised: 10/13/2023] [Accepted: 11/16/2023] [Indexed: 11/21/2023]
Abstract
PURPOSE To evaluate the effects of the specially designed nudging tableware, including a plate and bowl, on individual food choices in normal-weight young adults and preliminarily explore its mechanisms. We hypothesized that the toolset could increase the choice of vegetables and decrease that of rice. METHODS A randomized, single-blind, two-period crossover trial was carried out among 40 normal-weight university students in China. All subjects completed two buffets separated by an interval of one week, wearing the eye tracker. Vegetable choice, evaluated through the proportion of vegetables, was the primary outcome, and the weight of vegetables and rice were the secondary outcomes. The mechanisms of the decision-making process were preliminarily explored through eye tracking. RESULTS The usage of the nudging tableware significantly increased the proportion of vegetables and decreased the amount of rice taken (P<0.05), while insignificantly increased the weight of vegetables (P = 0.079). Eye tracking shows that the nudging plate significantly prolonged the food-choosing process and fixation duration on vegetables (P<0.05), and the latter was positively correlated to the increased quantity of vegetables while using the nudging plate (r = 0.493, P<0.01). CONCLUSION The specially designed nudging tableware might be an effective and practical tool to promote the choice of less rice and more vegetables. Mechanisms behind this change might include automatic and unconscious processes with the inconspicuously smaller capacity of the bowl and larger portion size of the vegetable segment, and increased attention triggered by the vegetable patterns and larger green underpainting.

Abstract
Despite the evidence that mothers' food purchasing behavior impacts the quality of children's diet, few studies have explored psycho-social factors influencing how mothers choose the food to buy for their children. To fill this gap, this study tested an extended Theory of Planned Behavior (TPB) model to predict mothers' tendency to seek information on food labels before purchasing food for children. Participants included 311 Italian mothers who completed a self-report questionnaire measuring their information-seeking behavior, TPB variables, anticipated regret and healthy-eater identity. Results from a Multiple Correspondence Analysis showed that mothers' information-seeking behavior involved a continuum of choices ranging from selecting conventional or prepackaged foods to choosing to read the food label before making a purchase. Besides, a Partial Least Squares-Structural Equation Modeling analysis showed that information-seeking behavior was positively predicted by intention (β = 0.309, p < 0.001) and healthy-eater identity (β = 0.195, p < 0.001). In turn, intention was positively affected by attitude (β = 0.208, p < 0.001), subjective norms (β = 0.155, p < 0.01), perceived behavioral control (β = 0.124, p < 0.05), anticipated regret (β = 0.193, p < 0.001), and healthy-eater identity (β = 0.191, p < 0.001). These findings emphasize that future initiatives could usefully target attitude, anticipated regret and self-identity to encourage mothers' informed food choices for their children.

Abstract
CONTEXT Food insecurity affects approximately 2.37 billion people worldwide. Individuals experiencing food insecurity are more likely to exhibit poor health-related endpoints. Dental caries, a highly prevalent noncommunicable disease, is modulated by an interplay between biological, behavioral, and environmental factors. OBJECTIVE This systematic review and meta-analysis aimed to assess whether individuals experiencing food insecurity were more likely to exhibit dental caries than individuals facing food security. DATA SOURCES The Web of Science, PubMed, Scopus, Embase, Ovid, CINAHL, LILACS, and APA PsycINFO databases were checked from inception to November 2021. Grey literature and Google Scholar were also examined. An updated search was conducted in August 2022. Observational studies were included if they evaluated the association between dental caries and food insecurity status. DATA EXTRACTION Data extraction was performed by two reviewers. DATA ANALYSIS Random-effects meta-analyses were conducted using R language. In total, 514 references were retrieved from databases, of which 14 articles were included in qualitative synthesis and 7 were merged into meta-analysis. The results of an inverse-variance meta-analysis (OR = 1.62; 95%CI, 1.01-2.60) and a meta-analysis of binary data (OR = 1.66; 95%CI, 1.36-2.02) demonstrated that food-insecure individuals were more likely to exhibit dental caries than food-secure individuals. Inverse-variance meta-analyses appraising multiple strata of food security also showed that individuals experiencing marginal food security (OR = 1.48; 95%CI, 1.28-1.72), individuals experiencing low food security (OR = 1.26; 95%CI, 1.01-1.57), and those experiencing very low food security (OR = 1.33; 95%CI, 1.04-1.71) were more likely to exhibit dental caries than individuals experiencing full food security. CONCLUSION Dental caries is associated with food insecurity. Individuals living with food insecurity are more likely to exhibit dental caries than those who have food security.

Abstract
Dietary risk, one of the major risk factors for the increasing burden of non-communicable diseases, is influenced by household food choices and purchases. A community-based cross-sectional study was conducted in 250 randomly selected households of an urban resettlement colony in Delhi to estimate the proportion of households purchasing different healthier food options during the last purchasing occasion and to identify its key determinants. Purchase of healthier options in staple items like wheat flour with fiber (100%), plant-based oils (97.9%), unpolished pulses (96.2%), and toned milk (94.5%) was high. Affordability and health considerations in food purchases were identified as key determinants.

Abstract
OBJECTIVES Myths about diet and nutrition are widespread and may seriously impact health and well-being. This study tests whether texts in a truth sandwich format, that is, texts presenting two blocks of factual, correcting information around a text block listing a myth and identifying it as false, are effective in reducing agreement with a range of nutrition myths. DESIGN Prestudy: observational survey; main study: 4 Text × 6 statement mixed experimental design. METHODS Out of 13 nutrition myths that were presented to 58 participants in a prestudy, the six most prevalent myths were selected for the main study. In the preregistered main study, 302 participants were randomly assigned to either reading one of three texts in the truth sandwich format addressing a nutrition myth or reading a text about healthy eating (control condition) before rating their agreement with a total of six nutrition myths. RESULTS Participants agreed less with the specific myth targeted by the truth sandwich text, while controls were not differentiating between them. CONCLUSIONS Thus, truth sandwiches are effective in reducing agreement with myths and can be harnessed to promote evidence-based dietary practices to promote health in the population.

Abstract
Introduction Nudging is a promising intervention technique that supports people in pursuing their healthy eating goals. Recent research suggests that, despite previous assumptions, disclosure of the presence of a nudge does not compromise nudge effectiveness. However, it is unknown whether attention to a nudge affects nudge effects. We assessed the role of attention systematically, by examining explicit and implicit attention to nudges, while also exploring healthy eating goals as a potential moderator. Methods Participants were assigned to a nudge (i.e., a shopping basket inlay with pictures of healthy items) or control condition (i.e., a shopping basket inlay with neutral pictures) and chose a snack in an experimental supermarket field study. Explicit and implicit attention (with a mobile eye-tracker) to nudges, healthiness of snack choice, and healthy eating goals were assessed. Results Results showed that attention to the nudge did not hamper the nudge's effect. Furthermore, individuals with strong healthy eating goals made healthier food choices in the nudge condition. Individuals with weak to non-existent healthy eating goals were not influenced by the nudge. Discussion Findings are in line with the viewpoint that nudging does not by definition work 'in the dark', and suggests that nudges support people in adhering to their healthy eating goal.

Abstract
Making healthy food choices is crucial for health promotion and disease prevention. While there are an increasing number of technology-assisted interventions to promote healthy food choices, the underlying mechanism by which consumption behaviours and weight status change remains unclear. Our scoping review and meta-analysis of seventeen studies represents 3988 individuals with mean ages ranging from 19·2 to 54·2 years and mean BMI ranging from 24·5 kg/m2 to 35·6 kg/m2. Six main outcomes were identified namely weight, total calories, vegetables, fruits, healthy food, and fats and other food groups including sugar-sweetened beverages, saturated fats, snacks, wholegrains, Na, proteins, fibre, cholesterol, dairy products, carbohydrates, and takeout meals. Technology-assisted interventions were effective for weight loss (g = -0·29; 95 % CI -0·54, -0·04; I2 = 65·7 %, t = -2·83, P = 0·03) but not for promoting healthy food choices. This highlights the complexity in creating effective interactive technology-assisted interventions and understanding its mechanisms of influence and change. We also identified that there needs to be greater application of theory to inform the development of technology-assisted interventions in this area as new and improved interventions are being developed.

Abstract
The high rate of deaths around the world from noncommunicable diseases (NCDs) (70%) is a consequence of a poor diet lacking in nutrients and is linked to lifestyle and environmental conditions that together trigger predisposing factors. NCDs have increased 9.8% of public health spending worldwide, which has been increasing since 2000. Hence, international organizations such as the WHO, the Pan American Health Organization, and the Food and Agriculture Organization of the United Nations have been developing strategic plans to implement government and economic policies to strengthen programs in favor of food security and nutrition. A systematic review is presented to document an analysis of the origin and characteristics of obesity, cardiovascular disease, chronic respiratory diseases, diabetes, and cancers affecting a large part of the world's population. This review proposes a scientifically based report of functional foods including fruits, vegetables, grains, and plants, and how their bioactive compounds called nutraceuticals-when consumed as part of a diet-benefit in the prevention and treatment of NCDs from an early age. Multifactorial aspects of NCDs, such as culture and eating habits, are limitations to consider from the clinical, nutritional, and biochemical points of view of everyone who suffers from them.

Abstract
Jordan has never conducted a nutrition survey to determine nutrient and energy intakes. The current study aimed to describe the energy and macronutrient consumed by the Jordanian population. A cross-sectional food consumption study was conducted, including a sample of Jordanians using two non-consecutive 24-h dietary recalls (24-h DR) between October 2021 and March 2022. A total of 2145 males and females aged 8 to 85 years old living in households were studied. The average of two 24-h DRs for each individual was converted into energy and nutrient intakes. After measuring weight, height, and waist circumference, the body mass index (BMI) and waist-to-height ratio (WHtR) were calculated. The percentage of under-reporters was higher in women than men (58.2% vs. 45.9%). Adults and older adult women had the highest prevalence of obesity (29.6%), while adults and older adult men had the highest prevalence of overweight (41.4%). There is a significant increase in energy intake in children, boys, and all adults, compared to the recommended calories. The mean energy percentage (E %) of total fat was 38%, exceeding the upper limit of the Acceptable Macronutrient Distribution Range (AMDR). At the same time, the mean daily dietary fiber intake fell below the recommended levels (ranging from 13.5 g in children to 19.5 g in older adults). The study population consumes more fat and less fiber than the recommended levels. Actions must be taken across all age groups to correct the deviation of energy and macronutrient intakes from the recommended dietary allowances.

Abstract
Retrospective self-reports are commonly used to assess dietary intake. Yet, their use is criticized as it is unclear whether the underlying assumptions for valid self-reports are met: Individuals have to consider the behavior of all days in the retention interval and weigh the behavior of all days equally. This study examines whether these assumptions for retrospective self-reports are met and whether interindividual differences in self-report performance are relevant regarding these assumptions. Ninety-two participants aged 18-61 years participated in seven sequential 24-h recalls and one retrospective 7-day recall concerning their intake of fruit, vegetables, and eggs. A multiple linear regression approach was used to examine the relation between the daily reported dietary intake and the 7-day recall. In the overall sample, the requirements for retrospective self-reports were not tenable. Distinguishing good and poor self-reporters based on a rational criterion showed that the requirements can be taken as given for good self-reporters, whereas poor self-reporters base their retrospective self-reports mostly on recency effects. The underlying requirements for retrospective self-reports appear to be met in two thirds of the sample, supporting the use of retrospective self-reports to capture dietary behavior. Future research should investigate characteristics separating good from poor self-reporters.

Abstract
The supermarket is a promising location for stimulating healthier food choices by nudging interventions. However, nudging healthy food choices in the supermarket has shown weak effects to date. The present research introduces a new nudge based on the concept of affordances - i.e., an animated character - that invites interaction with healthy food products and examines its effectiveness and appreciation in a supermarket context. We present findings of a series of three studies. In Study 1, evaluations of the new nudge were collected, revealing that the nudge was appreciated. In Studies 2 and 3, field experiments were conducted to test the nudge's effect on vegetable purchases in a real-life supermarket. Study 3 demonstrated that vegetable purchases increased significantly (up to 17%) when the affordance nudge was placed on the vegetable shelves. Furthermore, customers appreciated the nudge and its potential for implementation. Taken together, this set of studies presents compelling findings illustrating the potential of the affordance nudge for increasing healthy choices in the supermarket.

Abstract
BACKGROUND & AIMS Transitioning into higher education (HE) impacts health behaviours. Poor dietary and lifestyle behaviours may correlate and increase risk of co-morbidities. The introduction of the Okanagan Charter detailed the important role of health promotion within a HE setting. The aim of this study was to assess the relationship between dietary quality and lifestyle behaviours of students attending HE. METHODS Full-time students, aged 18+, were eligible to participate in this online cross-sectional study. Self-reported questions were asked in relation to demographics, body mass index (BMI), smoking, and COVID-19. A food frequency questionnaire measured dietary quality along with tools assessing alcohol use, sleep quality, perceived stress, and physical activity. Statistical analyses were performed using chi-square, one-way ANOVA, independent sample t-tests, Pearson's correlation, and multivariate linear regression. RESULTS Evidence of a correlation between poor diet quality and having a higher BMI (p = 0.040), higher alcohol consumption (p = <0.001), poorer sleep quality (p = 0.003), higher stress levels (p = 0.006) and smoking (p = 0.001) was found. Low fruit and vegetable consumption were associated with higher BMI (p = 0.013), higher alcohol consumption (p = <0.001), lower physical activity levels (p = 0.006), higher stress levels (p = <0.001), smoking (p = <0.001) and being male (p = 0.002). CONCLUSIONS This study provides data on the association between dietary quality and lifestyle behaviours among HE students and will inform healthy campus initiatives.

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
People with intellectual disabilities generally have poorer health outcomes compared with those who do not, including outcomes related to nutrition-related non-communicable diseases. Carers support people with intellectual disabilities in many aspects including habitual shopping and preparation of food, but their own nutrition knowledge and the influence this may have on dietary intakes of clients is unknown. We explored the nutrition knowledge of carers of people with intellectual disabilities in residential care settings, their dietary habits and their influence on clients' food shopping and preparation and therefore the diet consumed by their clients. Ninety-seven carers belonging to a large independent care sector organisation specialising in the care of people with an intellectual disability completed a validated general nutrition knowledge and behaviour questionnaire. Seventeen carers from the residential care settings were interviewed to contextualise practice. Knowledge about key dietary recommendations scored highly. Carers who had more work experience were found to have higher scores in 'making everyday food choices' (p = 0.034). Daily consumption of fruit and vegetables (at least one portion per day) was observed (for fruit by 46% of the carers and for vegetables by 60% of the carers), whilst most carers reported avoiding consuming full-fat dairy products, sugary foods and fried foods. The concept of a healthy diet; typical dietary habits of clients; role in food acquisition; and training in nutrition emerged as themes from the interviews. Carers discussed various topics including the importance of a balanced diet, cooking fresh foods and control of food portion sizes for clients relative to the care philosophy of a client-centred approach, which encapsulates client autonomy. Gaps in knowledge around specific nutrients, making healthy choices and cooking skills remain. Carers have an influence on clients' dietary choices; they are able to provide healthy meals and share good dietary habits with clients. Further training in nutrition is recommended for impact on clients' health.

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.

Mediterranean Diet and Sarcopenia Features in Apparently Healthy Adults over 65 Years: A Systematic Review. Nutrients 2023; 15:nu15051104.

Abstract
Low muscle mass combined with changes in physical function and muscle quality is defined as sarcopenia. In people > 60 years, sarcopenia reaches 10% and tends to increase with age. Individual nutrients, such as protein, may have a protective role against sarcopenia, but recent evidence suggests that protein alone has been ineffective in increasing muscle strength. Dietary patterns, instead, with a high "anti-inflammatory" potential, such as the Mediterranean dietary pattern, have been considered as an emerging dietary remedy against sarcopenia. The aim of this systematic review was to summarize the evidence of the role of Mediterranean diet in sarcopenia prevention and/or improvement, including recent data, in healthy elders. We searched published studies about sarcopenia and the Mediterranean diet until December 2022 in Pubmed, Cochrane, Scopus search engine and grey literature. In total, ten articles were identified as relevant: four cross-sectional studies and six prospective. No clinical trial was identified. Only three studies assessed sarcopenia presence and four measured muscle mass, which is an essential criterion in sarcopenia diagnosis. Mediterranean diet adherence had, in general, a positive role in muscle mass and muscle function, while the results were less clear with regard to muscle strength. Additionally, there was no evidence of a positive effect of the Mediterranean diet on sarcopenia. There is a need for conduction of clinical trials in order to reach cause-effects conclusions regarding the importance of the Mediterranean diet in sarcopenia prevention and management in Mediterranean and non-Mediterranean populations.

Abstract
Self-efficacy has a strong influence on children's eating behavior. Feeling capable of regulating one's eating behavior is especially relevant in situations of activation while facing temptations or experiencing negative emotions. Despite the relevance, there is no validated measure to assess children's self-efficacy to regulate eating behaviors in these domains. The present study examines the psychometric properties of the Self-Efficacy to Regulate Eating Behaviors Scale for Children based on a sample of 724 elementary school children in Portugal. The sample was split randomly into two groups, and a principal component analysis with Group 1 and a confirmatory factor analysis with Group 2 were carried out. The scale comprises two distinct but related factors-self-efficacy to regulate eating behaviors in activation and temptation situations and self-efficacy to regulate eating behaviors in negative emotional situations. Moreover, self-efficacy to regulate eating behaviors was positively and statistically related to self-regulation processes toward healthy eating, declarative knowledge about healthy eating, and attitudes and perceptions toward healthy eating. The present study provides preliminary evidence that the Self-Efficacy to Regulate Eating Behaviors Scale for Children is valid and reliable for evaluating children's self-efficacy in regulating their eating behaviors.

Abstract
Gestational diabetes mellitus (GDM) is one of the most common pregnancy-related endocrinopathies, affecting up to 25% of pregnancies globally. GDM increases the risk of perinatal and delivery complications, and the chance of developing type 2 diabetes mellitus and its complications, including cardiovascular diseases. This elevated risk is then passed on to the next generation, creating a cycle of metabolic dysfunction across generations. For many years, GDM preventive measures have had inconsistent results, but recent systematic reviews and meta-analyses have identified promising new preventative routes. This review aims to summarize the evidence investigating the efficacy of lifestyle treatments for the prevention of GDM and to summarize the effects of two lifestyle interventions, including physical activity and dietary interventions. Based on the present research, future studies should be conducted to investigate whether initiating lifestyle interventions during the preconception period is more beneficial in preventing GDM. In addition, research targeting pregnancy should be designed with a personalized approach. Therefore, studies should customize intervention approaches depending on the presence of modifiable and non-modifiable risk factors at the individual level.

Abstract
BACKGROUND While early onset colorectal cancer (EOCRC) has previously been defined as CRC in patients younger than age 50, recent screening guidelines have been lowered to 45. With more younger patients aged 45-50 are now being screened, incidence trend and outcomes of very early EOCRC (20-44) remains unclear. METHOD Surveillance, Epidemiology, and End Results database was analyzed between 2006 and 2016 using Joinpoint tool to evaluate annual percentage change (APC) in incident rates, focusing on race/ethnicity and socioeconomic status (SES). Cancer specific survival (CSS) was assessed using univariate and multivariate analysis. RESULTS 41,815 EOCRC patients met inclusion criteria. Incidence has increased significantly in both age groups (APC in age group 20-44 = 1.21 and 45-49 = 1.06). Increase incidence of very early EOCRC was observed in White and Hispanic racial/ethnic groups (ACP 1.68 and 2.63), as well as population from counties with high poverty, unemployment, language barrier, foreign born resident, and high school dropout rates (ACP 2.07, 1.87, 1.21, 1.28 and 2.02 respectively). Further, the 5-year CSS was worse in Black patients, and patients from counties with high poverty, unemployment and high school dropouts rates (Age group 20-44, 63.11%, 66.39%, 67.48% and 66.95% respectively). On multivariate analysis, living in high poverty counties was an independent risk factor for poorer CSS for very early EOCRC (HR 1.20, 95% CI 1.07-1.34, p = 0.002). Multivariate analysis was adjusted by sex, pathology type, site of disease, disease extension and surgical treatment history. CONCLUSION Very early EOCRC incidence increases in White, Hispanic and poor patients, and outcomes are worse for minority and low-income patients. Further study on very early EOCRC is needed among those patients.

Social Environmental Predictors of Lapse in Dietary Behavior: An Ecological Momentary Assessment Study Amongst Dutch Adults Trying to Lose Weight. Ann Behav Med 2023:7000437.

Abstract
BACKGROUND When losing weight, most individuals find it difficult to maintain a healthy diet. Social environmental conditions are of pivotal importance in determining dietary behavior. To prevent individuals from lapsing, insight in social environmental predictors of lapse in dietary behavior is needed. PURPOSE Identify social environmental predictors of lapse in dietary behavior, using ecological momentary assessment (EMA) amongst Dutch adults trying to lose weight. METHODS Adults (N = 81) participated in two 7-day EMA weeks. Six times a day semi-random prompts were sent. At each prompt, participants indicated whether a lapse had occurred and responded to questions assessing social support, descriptive norm, injunctive norm, social pressure, presence of others, and current location. Generalized estimating equations were used to examine associations with lapse. RESULTS Injunctive norm (OR = 1.07, 95% CI = 1.03-1.11), descriptive norm (OR = 1.04, 95% CI = 1.02-1.07), and social pressure (OR = 1.09, 95% CI = 1.05-1.14), all toward diverting from diet plans, predicted lapses. Social support toward sticking to diet plans and presence of others did not predict lapses. When controlling for a prior lapse, all other associations became nonsignificant. Lapses occurred most often at home and gradually occurred more often during the day. CONCLUSIONS Traditional public health perspectives have mainly focused on individual choice and responsibility for overweight related unhealthy lifestyles. This study shows that there may be opportunities to enhance intervention programs by also focusing on social norms and social pressure. The involvement of partners or housemates may create more awareness of the impact of (unintentional) social pressure on risk of lapsing, and reduce the level of exerted social pressure.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:1672. [PMID: 36767039 PMCID: PMC9914416 DOI: 10.3390/ijerph20031672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/13/2023] [Accepted: 01/14/2023] [Indexed: 06/18/2023]
Abstract
The present study aims to examine whether multiple dietary factors affect the mental health of older adults amid the COVID-19 pandemic. It proposes an integrative dietary framework that highlights environmental, nutritional, and social aspects of diet for healthy aging. Based on a sample of 7858 Chinese older adults, the associations between diet and depressive symptoms, along with the rural-urban divide, were examined using zero-inflated negative binomial regression. Overall, protein intake (incidence-rate ratio [IRR] = 0.89, p < 0.001), frequency of family dining together (IRR = 0.98, p < 0.001), and using tap water for cooking (IRR = 0.92, p < 0.01) were associated with lower incidence rates of depressive symptoms among older adults. Among rural older adults, frequency of family dining together (IRR = 0.97, p < 0.001) and tap water use (IRR = 0.89, p < 0.001) were associated with fewer depressive symptoms. However, urban residents who had a higher frequency of family dining together (IRR = 0.98, p < 0.05) and protein intake (IRR = 0.81, p < 0.001) exhibited fewer depressive symptoms. The findings revealed multifaceted dietary pathways towards healthy aging, which call for policies and interventions that improve diet quality for community-dwelling older adults.

Abstract
Factors such as regulations and health concerns shifted daily habits, including eating behaviors, during the early months of the coronavirus disease 2019 (COVID-19) pandemic. This comprehensive narrative review synthesizes research on eating behavior changes during the early months of the pandemic (February to June 2020), including changes in amount, rate, and timing of food consumption, types and healthfulness of foods consumed, the occurrence of other specified eating behaviors (eg, restrained eating or binging), and reasons for eating (eg, stress or cravings), among adults. A literature search using three EBSCOhost databases and Google Scholar was conducted to identify relevant articles made available in 2020. A total of 71 articles representing 250,715 individuals from more than 30 countries were reviewed. Findings show eating behaviors changed little during the early COVID-19 pandemic for most participants. Among those whose eating behaviors changed, increases in both intake and frequency of eating meals and snacks were more common than decreases. Findings on timing of eating and healthfulness of food consumed showed mixed results. However, when changes occurred in the type of food consumed, increases were more common for snacks, homemade pastries, white bread/pasta, legumes, and fruits/vegetables; decreases were more common for meats, seafood/fish, frozen foods, fast food, dark breads/grains, and dark leafy green vegetables. During the pandemic, binging, uncontrolled eating, and overeating increased, meal skipping decreased, and restrictive eating had mixed findings. Changes in factors such as emotions and mood (eg, depression), cravings, and environmental factors (eg, food insecurity) were related to changes in eating behaviors. Findings can inform clinical practitioners in efforts to mitigate disruptions to normal, healthy eating patterns among adults both in and outside of global health catastrophes.

Abstract
OBJECTIVES Proper eating habits ensure human health, so it is important to eat a balanced diet and learn the basics of proper eating from an early age. Adolescence is considered very important period for maintaining good health in terms of nutrition. METHODS In the study, we monitored the eating habits of 182 adolescents aged 14-19 years with different eating habits (73 vegetarians and 109 nonvegetarians) using a questionnaire on nutrition and determination of selected blood parameters - vitamin D, iron and n-3fatty acids. RESULTS Insufficient levels of vitamin D were determined in the whole group of adolescents, regardless of eating habits. Low iron concentrations negatively affect the biosynthesis of long-chain n-3 fatty acids, which was also reflected in our adolescents with alternative diets. CONCLUSIONS Based on the obtained results, it is necessary to place emphasis on the composition of the diet in adolescent age.

Abstract
INTRODUCTION Intuitive eating interventions aim to improve individual health and promote sustainable changes to one's relationship with food. However, there is no evidence-based consensus on the impact of intuitive eating interventions on diet quality. This systematic review aimed to investigate intuitive eating interventions and their impact on diet quality. METHOD PubMed, Embase, CINAHL, PsycInfo, and Cochrane databases were systematically searched to October 2021 for studies reporting interventions that encompassed the principles of intuitive eating and measured diet quality. Other health outcomes were used for secondary analysis. Findings were synthesized narratively. RESULTS Seventeen papers reporting 14 intervention studies (n = 3,960) were included in the review. All studies found a positive or neutral effect on diet quality following an intuitive eating intervention. A favorable change in eating behavior following these interventions was also observed. DISCUSSION Intuitive eating promotes an attunement to the body, which aids in improving diet quality because of increased awareness of physiological cues. The reduction of emotional and binge eating may also increase diet quality. IMPLICATIONS FOR RESEARCH AND PRACTICE Findings from the current review suggest that intuitive eating interventions are most effective face-to-face, in a group setting, and sustained for at least 3 months.

Abstract
Gestational diabetes mellitus (GDM) is the most prevalent pregnancy-related endocrinopathy, affecting up to 25% of pregnancies worldwide. Pregnant individuals who develop GDM have an increased risk of complications during pregnancy and birth, as well as future development of type 2 diabetes mellitus and CVD. This increased risk is subsequently passed along to the offspring, perpetuating a cycle of metabolic dysfunction across generations. GDM prevention strategies have had mixed results for many years, but more recent systematic reviews and meta-analyses have suggested potential new avenues of prevention. The objective of this review is to summarise the literature examining the efficacy of lifestyle interventions for the prevention of GDM and to uncover if specific individual-level characteristics influence this outcome. Based on the present literature, we determined that future trials should be designed to understand if initiation of lifestyle intervention in the preconception period is more effective to reduce GDM. Furthermore, trials initiated during pregnancy should be developed through the lens of precision prevention. That is, trials should tailor intervention approaches based on individual-level risk defined by the presence of modifiable and non-modifiable risk factors. Finally, future interventions might also benefit from just-in-time adaptive intervention designs, which allow for interventions to be modified in real-time based on objective assessments of an individual's response.

Abstract
Background/Aim The COVID-19 pandemic has been spreading throughout the world, having a significant impact on people’s lifestyles and health through social isolation and home confinement. The purpose of this study is to look into the impact of COVID-19 on diet and physical activity, as well as the possible influence factors, among ≥ 13-year-olds in Riyadh, Saudi Arabia. Materials and methods In the present study data were collected from 2,649 participants via an online survey. The Google online questionnaire was available from April 23 to May 6, 2020. During the COVID-19 lockdown, the survey asked respondents about their demographic characteristics (gender, age, education, economic income, and occupation), anthropometric data, physical activity, and diet habits. Results The study included 2,649 respondents, with 23.3% being male and 76.7% female. The majority of them were in good health and ranged in age from 21 to 29 years. 31% of those polled were overweight, and 14.3% were obese. The majority of respondents have a bachelor’s degree, diploma, or the equivalent, and a monthly family income of ≤ 25.000 SR. Those who were following a healthy diet (32.3%) were unable to maintain it during confinement, with males being affected more than females (42.7%, 29.3%, respectively, P = 0.004), and those most impacted were aged 21–29 years (38.0%, P = 0.046). Furthermore, 59.5% of males significantly failed to continue exercising during confinement compared to females who exercised consistently (P = 0.01). In terms of age, females aged less than 40 increased their exercise rate by about 23.4%, while males aged 40 and up decreased their exercise rate by 25.7% (P = 0.000). Moreover, 40.5% of the subjects’ weight increased, according to the findings. However, there was no significant effect on body mass index, despite the fact that 51% of participants were overweight or obese. Conclusion The data showed that the COVID-19 lockdown had a negative impact on maintaining a healthy diet (p = 0.023*) and physical activity (p = 0.000**).

Abstract
Antioxidants can scavenge free radicals in the human body and have been associated with a protective effect on the human body against a variety of diseases. As a part of normal cellular function, free radical production occurs continuously within the body at a cellular level. Excess-free radical production from endogenous or exogenous sources may result in a variety of diseases. Vitamins (A, C, and E), carotenoids, polyphenols, and flavonoids are some examples of common natural antioxidants. Among the different antioxidants quercetin, curcumin, and ascorbic acids have been extensively studied, and numerous reports on their antioxidant activity are available in the literature. Antioxidants are regarded as a key player in the current pandemic situation, and they play a key role as a preventive and controlling tool. There are a variety of herbal formulations and immune booster therapies available, many of which claim to contain various antioxidants and are effective against covid-19. Numerous herbal formulations and immune booster therapies are available and claimed to have different antioxidants and other constituents. In the present study simple, rapid, accurate, precise, and sensitive high-performance thin-layer chromatographic analytical method was developed for simultaneous estimation of quercetin, curcumin, and ascorbic acid. The developed method can effectively employ for different polyherbal formulations. The developed method was validated according to ICH guidelines. In the present study, an aluminum plate precoated with 60F 254 silica gel was used as a stationary phase whereas chloroform: ethyl acetate: formic acid (6:6:2.5 v/v/v) was used as a mobile phase. Chromatographic detection was performed with a Camag TLC scanner at 265 nm. The linearity range for the proposed method was found to be 500–1000 ng/band for all three analytes. The antioxidant potentiality of selected antioxidants was evaluated by an optimized UV visible spectroscopic-reducing power method. The reducing power method was optimized for the concentration and volume of reagent, incubation temperature, and time. The results of the study revealed that quercetin is having the best antioxidant potential compared to curcumin and ascorbic acid.

Abstract
An unhealthy diet is an important risk factor for disability and premature death. This study aimed to assess nutrition knowledge, dietary habits, and food label use among adults in Poland as well as to identify factors associated with diet-related behaviors. A cross-sectional survey was carried out in July 2020 on a non-probability quota-based sample of 1070 adult citizens of Poland. The most common sources of nutrition knowledge were news websites (41.8%) or family/friends (32.4%). Over one-quarter of adults in Poland were on a diet (28.7%). Over one-tenth of respondents (11.9%) consumed less than three meals per day. Half of the respondents (50.3%) declared that they use food labels when shopping, and 15.4% checked the nutrition information on restaurant menus. Female gender (OR:1.70; 95%CI:1.26-2.29; p < 0.001), presence of chronic diseases (OR:1.83; 95%CI:1.37-2.44; p < 0.001), regular physical activity (p < 0.001), and being a non-smoker (OR:1.45; 95%CI:1.02-2.06; p = 0.04) were significantly associated with higher odds of being on a diet. Females (OR:1.63; 95%CI:1.24-2.15; p < 0.001), respondents with higher education (OR:1.53; 95%CI:1.17-2.01; p = 0.002), those who had never been married (OR:1.49; 95%CI:1.07-2.07; p = 0.02), respondents with chronic diseases (OR:1.73; 95%CI:1.30-2.31; p < 0.001), those with regular physical activity (p < 0.05), as well as non-smokers (OR:1.42; 95%CI:1.04-1.95; p = 0.03) had higher odds of checking the food labels. This study showed a significant gap in nutrition knowledge among adults in Poland.

Abstract
We have developed an in situ methodology for determining nitrite concentration in processed meats that can also be used by unskilled personnel. It is based on a colorimetric film-shaped sensory polymer that changes its color upon contacting the meat and a mobile app that automatically calculates the manufacturing and residual nitrite concentration by only taking digital photographs of sensory films and analyzing digital color parameters. The film-shaped polymer sensor detects nitrite anions by an azo-coupling reaction, since they activate this reaction between two of the four monomers that the copolymer is based on. The sensory polymer is complemented with an app, which analyzes the color in two different digital color spaces (RGB and HSV) and performs a set of 32 data fittings representing the concentration of nitrite versus eight different variables, finally providing the nitrite concentration of the test samples using the best fitting curve. The calculated concentration of nitrite correlates with a validated method (ISO 2918: 1975) usually used to determine nitrite, and no statistically significant difference between these methods and our proposed one has been found in our study (26 meat samples, 8 prepared, and 18 commercial). Our method represents a great advance in terms of analysis time, simplicity, and orientation to use by average citizens.

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.

Abstract
During COVID-19, there has been a surge in public interest for information on immunity-boosting foods. There is little scientific support for immunity-supporting properties of specific foods, but strong evidence for food choice impacts on other health outcomes (e.g. risk of non-communicable disease) and environmental sustainability. Here, we relate online recommendations for "immunity-boosting" foods across five continents to their environmental and human health impacts. More frequently recommended food items and groups are plant based and have lower land use and greenhouse gas emission impacts plus more positive health outcomes (reducing relative risks of mortality or chronic diet-related diseases) per serving of food. We identify trade-offs between environmental outcomes of increasing consumption of recommended food items, with aquatic environment impacts increasing with food recommendation frequency. People's reliance on the Internet for health information creates an opportunity to consolidate behaviour change towards consuming foods with multiple co-benefits. Our study identifies win-win options for nudging online information-seeking behaviour towards more sustainable choices for terrestrial biodiversity conservation and human health.

JOURNAL OF ENVIRONMENTAL PSYCHOLOGY 2022; 81:101817. [PMID: 36523649 PMCID: PMC9742849 DOI: 10.1016/j.jenvp.2022.101817] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 04/28/2022] [Accepted: 05/05/2022] [Indexed: 05/15/2023]
Abstract
Policies to reduce meat consumption are needed to help achieve climate change targets, and could also improve population health. Public acceptability can affect the likelihood of policy implementation. This study estimated the acceptability of policies to reduce red and processed meat consumption, and whether acceptability differed when policies were framed as benefitting health or the environment. In an online experiment, 2215 UK adults rated the acceptability of six policies, presented in a randomised order. Prior to rating policies, participants were randomised to one of two framing conditions, with policy outcomes described either as benefitting health or the environment. Regression models examined differences in the primary outcome - policy acceptability (rated on a 7-point scale) - by framing. Labels were the most accepted policy (48% support), followed by a media campaign (45%), reduced availability (40%) and providing incentives (38%). Increasing price (27%) and banning advertising (26%) were the least accepted. A substantial proportion of participants neither supported nor opposed most policies (26-33%), although this fell to 16% for increasing price. There was no evidence that framing policy benefits from a health or environment perspective influenced acceptability (-0.06, 95%CIs: 0.18,0.07). Fewer than half of the UK sample expressed support for any of six policies to reduce meat consumption, regardless of framing measures as benefitting health or the environment. Conversely, fewer than half expressed opposition, with the exception of price, suggesting considerable scope to influence public opinion in support of meat reduction measures to meet environmental and health goals.

Abstract
Background Many theoretical frameworks have been used in order to understand health behaviors such as physical activity, sufficient sleep, healthy eating habits, etc. In most research studies, determinants within these frameworks are assessed only once and thus are considered as stable over time, which leads to rather 'static' health behavior change interventions. However, in real-life, individual-level determinants probably vary over time (within days and from day to day), but currently, not much is known about these time-dependent fluctuations in determinants. In order to personalize health behavior change interventions in a more dynamic manner, such information is urgently needed. Objective The purpose of this study was to explore the time-dependent variability of emotions, physical complaints, intention, and self-efficacy in older adults (65+) using Ecological Momentary Assessment (EMA). Methods Observational data were collected in 64 healthy older adults (56.3% men; mean age 72.1 ± 5.6 years) using EMA. Participants answered questions regarding emotions (i.e., cheerfulness, relaxation, enthusiasm, satisfaction, insecurity, anxiousness, irritation, feeling down), physical complaints (i.e., fatigue, pain, dizziness, stiffness, shortness of breath), intention, and self-efficacy six times a day for seven consecutive days using a smartphone-based questionnaire. Generalized linear mixed models were used to assess the fluctuations of individual determinants within subjects and over days. Results A low variability is present for the negative emotions (i.e., insecurity, anxiousness, irritation, feeling down) and physical complaints of dizziness and shortness of breath. The majority of the variance for relaxation, satisfaction, insecurity, anxiousness, irritation, feeling down, fatigue, dizziness, intention, and self-efficacy is explained by the within subjects and within days variance (42.9% to 65.8%). Hence, these determinants mainly differed within the same subject and within the same day. The between subjects variance explained the majority of the variance for cheerfulness, enthusiasm, pain, stiffness, and shortness of breath (50.2% to 67.3%). Hence, these determinants mainly differed between different subjects. Conclusions This study reveals that multiple individual-level determinants are time-dependent, and are better considered as 'dynamic' or unstable behavior determinants. This study provides us with important insights concerning the development of dynamic health behavior change interventions, anticipating real-time dynamics of determinants instead of considering determinants as stable within individuals.
