Rickerby A, Green R. Barriers to Adopting a Plant-Based Diet in High-Income Countries: A Systematic Review. Nutrients 2024; 16:823. [PMID: 38542734 PMCID: PMC10975979 DOI: 10.3390/nu16060823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 03/05/2024] [Accepted: 03/08/2024] [Indexed: 04/01/2024] Open
Abstract
Adopting a plant-based diet (PBD) has been shown to reduce the risk of developing certain diseases and is linked to environmental benefits. This review synthesises the evidence on the barriers adults aged 18 to 65 living in high-income countries (HIC) may experience when adopting a PBD. A systematic literature review was conducted using four search databases: Medline, Embase, Global Health, and Web of Science. Barriers were mapped to behaviour change strategies using the COM-B model. Ten studies were included in the final review, including 1740 participants. Five were qualitative, four were cross-sectional, and one was a pre- and-post-intervention study. In total, 40 barriers were identified and synthesised into 11 themes: financial, lack of knowledge, emotional, health, convenience, social, enjoyment of meat, environmental, accessibility, personal ability, and media. Of the 40 barriers, nutritional intake/requirements (categorised into the "health" theme) had the most evidence. This barrier encompassed concerns around being able to meet nutritional needs if an individual were to adopt a PBD. Habits (in the "personal ability" theme), which included established eating habits and habitual behaviours relating to animal-source foods, had the second most evidence alongside the barrier of not knowing what to eat as part of a PBD (in the "lack of knowledge" theme). Education interventions and communication/marketing policies were the behaviour change mechanisms mapped onto these barriers. Future interventions should focus on informing individuals about what to consume as part of a nutritionally balanced PBD and facilitating habitual dietary change.

Benedetto L, Sabato I, Costanza C, Gagliano A, Germanò E, Vetri L, Roccella M, Parisi L, Scaffidi Abbate C, Ingrassia M. Diet-Related Attitudes, Beliefs, and Well-Being in Adolescents with a Vegetarian Lifestyle. Healthcare (Basel) 2023; 11:2885. [PMID: 37958029 PMCID: PMC10650094 DOI: 10.3390/healthcare11212885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 10/04/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023] Open
Abstract
Vegetarianism can meet healthy, ethical, or ecological values (such as equality and protection of animals or the environment). At the same time, it can represent a response to the need for self-determination in adolescence. Furthermore, some studies show vegetarians have greater depressive risk and a lower sense of body satisfaction. Considering the spread of non-meat diets in the Western world, researchers have investigated the benefits and risks to physical and psychological health. Despite this, few studies have been conducted on factors influencing adolescent's vegetarian diet-related attitudes. Through self-administered loosely structured interviews, this research investigated factors potentially associated with vegetarian choices in adolescence. It checked (a) gender differences in vegetarian choices; (b) religious, familial, ethical, or health factors implied in vegetarian choices; and (c) indicators of well-being among young vegetarians. The findings suggest that for our sample, non-vegetarians have lower scores on health-related questions than others, while for vegetarian adolescents, the benefits of vegetarianism mainly depend on their ethical stances, beliefs, and values. Conversely, it is unrelated to factors such as the desire to lose weight, dissatisfaction about one's body shape, or depressive feelings.

Abstract
Food choice has long been recognized as an interaction between psychological, social, cultural, economic, and biological forces through life course events and experiences. Adolescence is a particularly sensitive life stage during which personal and external environments influence food decisions and attitudes that can have long-term implications. Young people represent future households, yet little is understood about their perspectives on, and experiences of, their foodscape. To address this, a photovoice study with thirty-two students was undertaken at three state high schools with differing foodscapes in South East Queensland (Australia). Adolescent perspectives on foodscapes highlighted the food in front of them (either common or favourite foods), food routines, their emotional relationship with food, and the important role that family has in shaping their relationship with food (in particular mothers). Adolescents demonstrated an astute awareness of healthy/good and unhealthy/bad foods in relation to ingredients, ways of eating and different types of foods. Yet they expressed noticeable confusion on this matter, referring to some foods as "healthy-ish", or describing a "balanced" diet as consuming something healthy followed by something unhealthy. We found that adolescents are inundated by discretionary foods on a daily basis, however, are not particularly cognisant of them. These findings have direct implications for preventative health messages targeting adolescents.

Abstract
Plant-based diets (PBDs) refer to dietary habits that reduce the consumption of animal-based products and increase the consumption of nutritionally rich plant foods. PBD's have been shown to provide significant health benefits, such as reducing obesity and improving psychological wellbeing, and are environmentally friendly. However, few studies have investigated factors that influence young people's thoughts and attitudes toward following a PBD in western societies, particularly in the United Kingdom. Understanding these factors may benefit public health interventions that encourage the consumption of more fruit and vegetables. The aim of this study was to explore the factors that affect young people's intentions toward following a PBD. Twenty-one young people (18-24 years) participated in this qualitative study. Participants were asked about their views of PBDs in a semi-structured interview. Thematic analysis was utilized to explore views and the barriers and facilitators to following a PBD. The Theory of Planned Behavior (TPB) was used as a framework to organise the findings. Within attitudes, the sub-themes identified were an awareness of a healthy diet, environmental concerns, health concerns and distrust, perceptions of PBDs and associated stereotypes, perceived restriction and lack of enjoyment, and need for education. Within subjective norms, the sub-themes identified were cultural and familial norms, peer influence, and exposure through social media. Within perceived behavioral control (PBC), the sub-themes identified were a lack of independence and parental control, lack of knowledge and perceived difficulty, lack of inclusiveness and accessibility, and inconvenience. Overall, the findings suggest that increased provision of education and knowledge about PBDs to young people, and widening access to PBDs, could encourage and help improve their understanding and intention to follow this dietary style. Tailored health promotion strategies, which also consider additional barriers and facilitators found within this study, could motivate young people to consume a more PBD.

Abstract
In Indonesia, school feeding programs have not been established nationally due to the government's limited budget. To examine the possibility of copayment for school feeding programs, parents' intentions to use the school feeding programs and their willingness to pay (WTP) for these programs should be considered. We conducted an online questionnaire survey among the parents of junior high school students in all five public junior high schools in the Kepanjen District of Malang Regency, East Java Province, Indonesia. We used the contingent valuation method to elicit parents' WTP for school feeding and calculated the price elasticity of school feeding. Factors associated with the WTP were examined using logistic regression analysis. Of the 940 participants, 90% intended to use school feeding programs, and 30% were willing to pay Rp 15,000 (USD 1.05) or higher per meal. Of the 944 students (participants' children), all but two students consumed meals or snacks at school, with 74% consuming foods three or more times daily. Higher WTP for school feeding was associated with frequent food consumption at school, higher income, and a better perception of meals at school. In contrast, lower WTP was associated with more household members. Most parents intended to use school feeding programs with certain WTP irrespective of the price of school feeding. Therefore, school feeding in Indonesia might be expanded through copayment.

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.

Abstract
Adolescence is a critical time of physical, psychological and social development, and thus, optimal nutritional intakes are required during this life stage. Despite this, adolescence is recognised as a period of nutritional vulnerability, with many reportedly failing to meet current dietary guidelines. The school-setting presents a favourable environment to intervene and promote positive dietary behaviours and is also inclusive regardless of socio-economic status. However, a lack of consensus exists on how best to utilise schools to facilitate improvements in dietary behaviours among this age group. Whilst previous research has focused on identifying the factors motivating dietary choices within the school-setting, less is known on the optimum strategies to enhance these dietary choices which could positively contribute to the design of future interventions. It is reported that adolescents have good nutritional knowledge, although this does not appear to be a central consideration when making their dietary choices. Alternative factors at the individual (taste, visual appeal, familiarity, food quality, price, portion size, value for money, time/ convenience), social (peer influence), physical (product placement) and macro environment (food availability) levels have been frequently cited as important influences on adolescents' dietary choices in school. Although school-based interventions have shown potential in achieving positive dietary change among adolescents, more research is needed to determine the most effective methods in improving dietary behaviours in schools. This review summarises the key factors which influence adolescents' school-based dietary choices and the effectiveness of previously conducted interventions, identifying promising components for consideration when developing future dietary interventions within the school-setting.

Abstract
This study aimed to explore and evaluate factors that impact the dining experience of vegetarian consumers within a range of vegetarian-friendly restaurants. To explore the factors and understand consumer experience, this study analyzed a vast number of user-generated contents of vegetarian consumers, which have become vital sources of consumer experience information. This study utilized machine-learning techniques and traditional methods to examine 54,299 TripAdvisor reviews of approximately 1,008 vegetarian-friendly restaurants in London. The study identified 21 topics that represent a holistic opinion influencing the dining experience of vegetarian customers. The results suggested that "value" is the most popular topic and had the highest topic percentage. The results of regression analyses revealed that five topics had a significant impact on restaurant ratings, while 12 topics had negative impacts. Restaurant managers who pay close attention to vegetarian aspects may utilize the findings of this study to satisfy vegetarian consumer requirements better and enhance service operations.

Abstract
Carotenoids, polyphenols, and minerals (CPMs) are representative bioactive compounds and micronutrients in plant-based foods, showing many potentially positive bioactivities. Bioaccessibility is a prerequisite for bioactivities of CPMs. Cell wall polysaccharides (CWPs) are major structural components of plant cell wall, and they have been proven to affect the bioaccessibility of CPMs in different ways. This review summarizes recent literatures about the effects of CWPs on the bioaccessibility of CPMs and discusses the potential mechanisms. Based on the current findings, CWPs can inhibit the bioaccessibility of CPMs in gastrointestinal tract. The effects of CWPs on the bioaccessibility of polyphenols and minerals mainly attributes to bind between them, while CWPs affect the bioaccessibility of carotenoids by changing the digestive environment. Further, this review overviews the factors (environmental conditions, CWPs properties and CPMs characteristics) affecting the interactions between CWPs and CWPs. This review may help to better design healthy and nutritious foods precisely.

Abstract
OBJECTIVE This study aimed to describe meat consumption rationalisation and relationships with meat consumption patterns and food choice motivations in New Zealand adolescents. DESIGN This was a cross-sectional study of adolescents from high schools across New Zealand. Demographics, dietary habits, and motivations and attitudes towards food were assessed by online questionnaire and anthropometric measurements taken by researchers. The 4Ns questionnaire assessed meat consumption rationalisation with four subscales: 'Nice', 'Normal', 'Necessary' and 'Natural'. SETTING Nineteen secondary schools from eight regions in New Zealand, with some purposive sampling of adolescent vegetarians in Otago, New Zealand. PARTICIPANTS Questionnaires were completed by 385 non-vegetarian and vegetarian (self-identified) adolescents. RESULTS A majority of non-vegetarian adolescents agreed that consuming meat was 'nice' (65 %), but fewer agreed that meat consumption was 'necessary' (51 %). Males agreed more strongly than females with all 4N subscales. High meat consumers were more likely to agree than to disagree that meat consumption was nice, normal, necessary and natural, and vegetarians tended to disagree with all rationalisations. Adolescent non-vegetarians whose food choice was motivated more by convenience, sensory appeal, price and familiarity tended to agree more with all 4N subscales, whereas adolescents motivated by animal welfare and environmental concerns were less likely to agree. CONCLUSIONS To promote a reduction in meat consumption in adolescents, approaches will need to overcome beliefs that meat consumption is nice, normal, necessary and natural.

Abstract
Objective To explore the acceptability and feasibility of choice architecture strategies for dietary change in UK secondary school canteens from the perspectives of pupils, school staff and catering providers through qualitative focus groups and interviews. Results Three focus groups with adolescents (n = 15; mean age 13.7 years; standard deviation 1.9) and eight interviews with school staff and caterers recruited from one school and catering provider in Coventry UK were undertaken. The most acceptable choice architecture strategies for intervening to drive healthy dietary choices are those that make use of proximity and positioning, on the basis that convenience was one of the main drivers for food/drink selections. Acknowledging adolescents’ desire for autonomy and for food to be familiar and predictable was considered important in enhancing acceptability. Challenges to the feasibility of nudge strategies included concerns about behavioural issues, increased food waste, and a decline in uptake of canteen purchases. The design of food choice architecture interventions for secondary school settings should consider the specific characteristics of this age group and setting to ensure successful implementation.

Abstract
A plant-based diet is more sustainable, and research suggests that adolescents obtain health benefits from adopting a more plant-based diet (e.g., improved weight control, increased cardiovascular health). However, it is still unclear what factors promote/hinder their intention to attain such a dietary habit. The aim of the present study was to examine factors affecting adolescents' willingness to consume more plant-based foods. In a theory-based interview study, using the Reasoned Action Approach as framework, adolescents were interviewed concerning their reasons for their (un)willingness to adopt a more plant-based diet. A total of 11 adolescents (15/16 years old; 7 girls, 4 boys) were recruited and interviewed at two secondary schools in the Dutch Province of Limburg, the Netherlands. None of the interviewees reported being vegan/vegetarian/flexitarian. The interviewed adolescents overall expressed little interest in adopting a more plant-based diet. They appeared to have little knowledge of what would comprise a more plant-based diet and showed a lack of awareness of the benefits for personal and planet health. Further, most participants indicated lacking skills to prepare plant-based meals. Despite that, they felt confident they would be able to consume a much more plant-based diet for a definite period. Most importantly, the low intention to consume more plant-based food options was explained by the perceived (or expected) poor taste of these foods. We conclude that education on the plant-based diet (i.e., increasing awareness of the benefits, and skills to procure or prepare a plant-based meal) might increase both knowledge and plant-based food familiarity. The latter being important as food familiarity is key in promoting its acceptance.

Children's Perceptions about Environmental Sustainability, Food, and Nutrition in Chile: A Qualitative Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189679. [PMID: 34574616 PMCID: PMC8467886 DOI: 10.3390/ijerph18189679] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/08/2021] [Accepted: 09/09/2021] [Indexed: 12/23/2022]
Abstract
Food is inextricably linked to human health and environmental sustainability; however, very little is known about children’s perceptions of the concept of sustainability in the context of food choices. We aimed to explore the perceptions of Chilean schoolchildren about environmental sustainability, food, and nutrition. Eight online focus groups were conducted with boys and girls aged 8–9 (n = 30). Questions related to environmental sustainability, pocket money, and food characteristics such as price, front-of-package (FOP) warning label, and eco-labels were included. Data analysis was conducted using ATLAS.ti through a hybrid content analysis approach. Five central themes were identified: (1) children’s favorite snacks, (2) knowledge of sustainability, (3) sustainability and eco-labels use, (4) healthfulness of food products, and (5) pocket money and food prices. Most children were not aware of the meaning of “environmental sustainability”, but the concept was understood when it was explained in plain language. Participants showed awareness about the environmental impact of their eating behavior, had a positive perception of eco-labels, and identified food with fewer warning labels as “better” options. Results indicate that children understand the concept of sustainability in food if it is communicated clearly, and that eco-labels may be an effective tool in that effort.

Abstract
BACKGROUND In Bangladesh overweight and obesity among urban school children are on the rise. Urban school children tend to consume foods dense in calories and few fruits and vegetables which is associated with overweight and obesity. The current study explored the barriers and opportunities for promoting healthy diets among school children from the perspective of teachers and parents in Dhaka, Bangladesh. METHODS We conducted 14 key informant interviews with teachers and principals, six focus group discussions with 31 mothers of school children (5 to 15 year old) and 14 structured observations of the school food environment. Inductive thematic analysis was performed manually. RESULTS Schools were important for development of food preferences of children, however, most school cafeterias provided foods based on profit rather than health considerations. A shift in food culture resulted in making eating out acquire many meanings beyond convenience. Mothers, especially those who were employed, struggled to prepare healthy foods due to time pressure. Mothers were generally concerned about chemicals added to raw foods in markets which led to limited fruit and vegetable consumption. CONCLUSIONS There were many challenges to promoting healthy foods to school children within and outside the school. It is important to formulate policies and guidance to create a supportive environment for healthy foods in and in the proximity of schools. It is also important to educate consumers about identifying and choosing healthy foods. Laws related to food safety should be adequately implemented to boost the population's confidence in safety of available healthy foods in the food system.

Abstract
The study aim was to investigate the role of foodbanks in the context of food insecurity and explore food choices and eating behaviours amongst users. Food insecurity is associated with poor diet quality and obesity; however, the dimensions that influence food choices and eating behaviour remain unclear. Face-to-face interviews were conducted with individuals who had visited a faith-based foodbank in Perth, Western Australia. Participants were thirty-three service users who had collected a food hamper from the foodbank. Interview transcripts were analyzed using thematic analysis. Four main themes emerged: Ties you over until pay day; Food hamper supporting meals and fruit and vegetable consumption; Food choices supplementing hamper; Household gatekeeping and food control. Participants were complimentary about the content of the food hamper received which included a variety of fresh produce. A key new finding was the frequent purchase and consumption of meat and processed meat to supplement the food hamper provision. Future work and interventions to improve eating behaviour and reduce food-related financial pressure for those vulnerable to food insecurity include further exploration of the dimensions influencing food choices (i.e., cultural norms, habits, symbols); exposure to healthy and tasty plant-based meals, (i.e., tasting low-cost and tasty vegetable-based meals); parenting training focused on handling child/partner food choice influences, and, enforcing household rules governing food.

Abstract
Meat reduction has important implications for public health and the environment. With people more likely to reduce their meat consumption than eliminate it completely, there is increased interest in flexitarian (reduced meat) diets. Young adults in particular are transitioning towards a flexitarian diet, yet there is very little research on this crucial sub-set of the population. In this research, 23 interviews are conducted with young adults aged 18-35 in New Zealand to explore their lived experiences (i.e., motivations, strategies and barriers) towards flexitarianism. The research finds young adults are encouraged to transition towards flexitarianism due to increased control, through a transition away from home which is enabled through cooking strategies, social support and experimentation. Young flexitarians are motivated to reduce meat consumption due to concern about various individual (health, variety, price, reduce social unease) and altruistic (environment and ethics) motivations. Continued meat consumption is mainly driven by a need to compromise at social gatherings, and due to positive associations with variety, nutrients and fullness as well as taste due to cravings. The findings have several implications for social marketing and public health, particularly around supportive social settings, seeing flexitarianism as a 'not all or nothing approach' (one does not have to be a full vegetarian or a meat eater, but can instead be something in between), positive emotions such as pride associated with meat reduction, and that documentaries and social networks are key triggers for meat reduction.

Abstract
Alternative proteins are receiving increased global attention. This burgeoning interest in plants (especially plant-based meat alternatives), insects, algae, and cultured meat has been attributed to their reported health benefits, lower environmental impact and improved animal welfare compared to conventional animal-based meat. Food producers and the media are promoting acceptance of these products, claiming superior nutritional, environmental and ethical credentials and a desirable novel sensory experience. However, the evidence supporting these claims remains unclear. In this review, we summarise the main evidence underlying the nutritional, sensorial, economical, ethical, and environmental reasons reported for the rise in consumer demand for alternative proteins. We found many of these reasons to lack a strong evidence base. For instance, evidence is emerging for the nutritional benefits of plant-based meat alternatives, but present claims are largely based on established evidence for plant-based diets. Significant research gaps remain, especially longitudinal evidence on the sustained effects of replacing conventional animal-based proteins with alternative sources. For many alternative proteins, challenges exist in achieving desirable sensory properties akin to animal-based meat to promote their acceptance by consumers. Overall, fundamental shifts in the food system are required to create a culture in which healthful and sustainable food choices are the norm.

Abstract
Studies of adults report that perceived taste affects food choices and intake, which in turn may have an impact on health. However, corresponding evidence on adolescents is limited. Our aim was to summarize current evidence of the impact of taste perception on food choice preferences or dietary intakes among adolescents (mean age 10-19.9 years). Systematic searches identified 13 papers, 12 cross-sectional and one cohort study published between 1 January 2000 to 20 February 2020 assessing the impact of taste (using phenotypic and/or genotypic markers) on food choices in adolescents without any disease conditions. Qualitative assessment in the current review indicated that individuals sensitive to bitter tastes often have a lower preference of bitter-tasting food and higher preference for sweet-tasting food. A meta-analysis of three studies on bitter-taste sensitivity revealed no difference in preference for bitter-tasting vegetables between bitter tasters and non-tasters (standardized mean difference (SMD) = 0.04; 95% CI: -0.18, 0.26; p = 0.72). Overall, a limited number of studies were available for review. As a result, we report no clear relationship between taste perception and food choices or intake in adolescents. More studies are needed to evaluate the link between adolescents' taste perceptions and dietary intake.

Abstract
Excess body weight and risky alcohol consumption are two of the greatest contributors to global disease. Alcohol use contributes directly and indirectly to weight gain. Health behaviours cluster in adolescence and track to adulthood. This review identified and synthesised qualitative research to provide insight into common underlying factors influencing alcohol use and unhealthy eating behaviours amongst young people aged 10–17. Sixty two studies met inclusion criteria. Twenty eight studies focused on alcohol; 34 focused on eating behaviours. Informed by principles of thematic analysis and meta-ethnography, analysis yielded five themes: (1) use of alcohol and unhealthy food to overcome personal problems; (2) unhealthy eating and alcohol use as fun experiences; (3) food, but not alcohol, choices are based on taste; (4) control and restraint; and (5) demonstrating identity through alcohol and food choices. Young people faced pressure, reinforced by industry, to eat and drink in very specific ways, with clear social consequences if their attitudes or behaviour were deemed unacceptable. No qualitative studies were identified with an explicit and concurrent focus on adolescent eating behaviours and alcohol consumption. Further exploratory work is needed to examine the links between food and alcohol in young people’s emotional, social and cultural lives.

Abstract
ABSTRACT Objective To evaluate the interpretation by adolescents of messages contained in the Dietary Guidelines for the Brazilian Population. Methods Qualitative study of adolescents distributed across “conversation circles”. Each group received messages about healthy eating from the Dietary Guidelines and was instructed to develop materials containing their own interpretation thereof, using appealing wording and format. Content analysis was then used to evaluate these materials. Results Presentation of the produced materials revealed a focus on placing the participants at the center of the process and highlighting the dynamic and innovative nature of each strategy. Corpus analysis identified three clusters of meaning: (I) Food classification and selection model: The participants showed comprehension of the different formulations of foods and their impacts on health, but using other terms. A reductionist understanding of the composition of a healthy diet was observed; (II) Environment and eating practices: the environment was characterized as conducive or not to healthy eating, and open-air markets were recognized as spaces for healthy choices. Creating recipes was judged a wise choice to be shared; and (III) Diet-related individual and collective wellness: consequences of unhealthy food intake were linked to physical and emotional well-being. Concerns were raised about the use of natural resources and the impact of pesticides on individuals and the environment. Conclusion To facilitate understanding of the Dietary Guidelines, the wording of its messages must be adapted, and the discussion about healthy eating and proper diet must be broadened to ascribe greater value to the act of cooking in this population.

Abstract
Developmental shifts during early adolescence relate to type 1 diabetes (T1D) self-management, increased risk of emotional distress, and worsening health status. Less is known about positive experiences related to T1D. This study evaluated associations of positive well-being (PWB) with diabetes burden, self-management, and glycemic control. Youth (N = 55, age = 12-13 years; X̄ age = 12.75 + 0.56 years, 50.9% male, 38.2% non-Caucasian) reported PWB, depressive symptoms, and diabetes burden. Parents reported on overall T1D adherence. Adherence behaviors and glycemic control were assessed objectively. Higher PWB correlated with lower depressive symptoms (r s = -.45), less diabetes burden (r s = -.48), and better glycemic control (r s = -.43), all p < .01. When controlling for diabetes duration, higher PWB correlated with lower depressive symptoms and better glycemic control. PWB was not related to demographics or adherence. Initial exploration suggests PWB is related to key diabetes constructs, and maybe valuable to consider along with efforts to support youth with T1D during a vulnerable developmental period.

Abstract
Vegetarian diets have become a prominent area of interest. However, little research has focused on the attitudes and perceptions on vegetarian diets. The purpose of this scoping review was to methodologically search the literature and summarize public perceptions and attitudes towards a vegetarian diet. Using the information found from this review, the Health Belief Model can be applied to shape future health promotion initiatives to move individuals towards a vegetarian or plant-based diet. The main findings indicate that vegetarian diets are generally perceived in a positive light. There are many barriers to consuming this diet such as health concerns, an unwillingness to make dietary changes, and an enjoyment of eating meat.

Abstract
In this Special Issue, entitled "Food choice and Nutrition: A Social Psychological Perspective", three broad themes have been identified: (1) social and environmental influences on food choice; (2) psychological influences on eating behaviour; and (3) eating behaviour profiling.The studies that addressed the social and environmental influences indicated that further research would do well to promote positive food choices rather than reduce negative food choices; promote the reading and interpretation of food labels and find ways to effectively market healthy food choices through accessibility, availability and presentation. The studies on psychological influences found that intentions, perceived behavioural control, and confidence were predictors of healthy eating. Given the importance of psychological factors, such as perceived behavioural control and self-efficacy, healthy eating interventions should reduce barriers to healthy eating and foster perceptions of confidence to consume a healthy diet. The final theme focused on the clustering of individuals according to eating behaviour. Some "types" of individuals reported more frequent consumption of fast foods, ready meals or convenience meals or greater levels of disinhibitiona nd less control over food cravings. Intervention designs which make use of multi-level strategies as advocated by the Ecological Model of Behaviour change that proposes multi-level (combining psychological, social and environmental) strategies are likely to be more effective in reaching and engaging individuals susceptible to unhealthy eating habits than interventions operating on a single level.
