Enhancing food sustainability in the acute hospital setting - a nurse-led study of patient food.

Intensive global food production causes soil, water and air pollution, which has a negative impact on our health and future ability to produce sufficient nutritious food. Plant-based diets have the potential to reduce the environmental damage associated with the global food chain. The project sought to understand drivers of food waste and to improve food sustainability in a busy, tertiary referral hospital in England. Ward-level food waste was quantified. Qualitative data were collected using informal interviews with staff and additional data utilised the patient feedback survey. Ward-level food packaging waste and patient food choices were quantified using data on patient menu choices. The carbon footprint of patient food choices was calculated. Beef was the most popular menu choice, and was the main contributing factor to the high environmental impact of the hospital food chain. Increasing the visibility of vegetarian options on the menu led to a four-fold rise in these meals being chosen, which reduced the carbon footprint of the patient meal service. Recycling food packaging was also started, but there are challenges to widespread implementation. The project was successful, but it remains a starting point from which to increase food sustainability across the NHS and care sector catering provision.

Differences in perspectives on sustainability attributes of dietary protein sources between reduced animal-based dieters and nondieters

The United Nations Sustainable Development Goals envision a sustainable future that includes a shift in food consumption, aiming to reduce anthropogenic environmental impacts. Protein sources are crucial in sustainable diets because of their high environmental influence. Although consumers play a pivotal role in driving the shift towards more sustainable food consumption patterns, research on the perceptions of specific dietary groups regarding protein sources is limited. In this study, the perceived sustainability attributes of eight common protein sources between reduced animal-based dieters (RABs) and nondieters (NDs) were evaluated. Using a cross-sectional survey, we measured demographic data, food consumption frequency, perceived healthiness, and environmental friendliness. We performed conjoint analysis on the importance of the protein sources’ sustainability attributes (nutritional score, ecological score, price, product category). In total, 294 RABs and 247 NDs participated. The majority of the sample consisted of highly educated, childless women aged 18–39 years with high incomes, residing in cities, and responsible for food in their households. The presence of a nutritional score had a positive effect on both consumer groups’ perceptions of product sustainability, whereas the presence of an ecological score negatively affected consumer preferences for more sustainable products. The perceptions of the sustainability of protein sources varied significantly between RABs and NDs. Overall, RABs underestimated the healthiness of animal-based products, whereas NDs underestimated the environmental impact of protein sources. Among the animal-based protein sources, eggs and fish were seen as the most sustainable, with significantly higher means for NDs (p < 0.001). Among the sustainability attributes, plant-based foods and nutritional scores had a significant positive effect on both groups’ choices. For RABs, all animal-based protein sources had a significant negative effect on food choice. These results support the assumption that nutritional scores can improve the nutritional quality of food choices, whereas ecological scores can reduce the environmental impact of food choices. These findings underscore the need for tailored communication strategies and interventions to promote sustainable food choices among diverse dietary groups.

Orthorexia Nervosa - unhealthy obsession on healthy lifestyle

Introduction: Eating disorders have expanded rapidly in recent years, with social media platforms like Instagram and TikTok playing a significant role. These platforms often showcase idealized images of healthy eating and body image, exposing young people to an overwhelming amount of information. This overstimulation can contribute to the development of various eating disorders. In our study, we focus particularly on orthorexia nervosa. Review methods: Our study was conducted as a literature review, with data gathered from PubMed and Embase. The state of knowledge: Orthorexia Nervosa (ON), introduced by Steven Bratman in 1997, could be defined as an unhealthy obsession with healthy eating. This obsession leads to strict dietary restrictions, where individuals often exclude certain food types, such as preservatives and GMOs, and experience significant stress and anxiety over food choices, planning, and preparation methods. The fixation on food purity can result in social isolation, anxiety, and major disruptions to daily life. In comparison to other eating disorders like anorexia nervosa and obsessive-compulsive disorder (OCD), ON is characterized by its focus on food quality rather than body image or weight. Conclusions: The classification of orthorexia as a mental disorder and the need for its recognition in DSM-5 are still debated. However, growing concern about its impact on mental and physical health has led to increased research and awareness.

Conceptualizing university students’ food choices based on theory of planned behavior

Background Several students use hostel facilities offered by their colleges and universities while pursuing higher education. A crucial change is witnessed in their food habits during their stay at the campus, which is vastly different from their home experience. Method The study employs the theory of planned behavior to conceptualize and understand the food choices of university students while following the qualitative research methodology and the phenomenological approach. The snowball sampling method is applied to select participants for the study. We selected twenty-six undergraduate and postgraduate students pursuing programs in technical and health science from a private university at Udupi with residence in the university campus for two to four years. Interviews with candidates were conducted online and audio-recorded with participants’ consent. Results The transcribed interviews were coded and categorized to obtain themes, which were then conceptualized to develop the model based on the theory of planned behaviour. The duration of their stay on campus allowed students to gain a perspective on the food events and the food they consumed at the university dining facility (UDF) guided by factors, such as taste, price, availability of time(during academic activity), accessibility to healthy food, academic stress and lack of knowledge on nutrition. Two factors emerged from the interviews, one, there was no display in the dining facility about the nutritional value of the food served; and, second, students preferred to dine out on unhealthy food rather than at the university because food from outside the campus, even though unhealthy, was easier on the pocket. Conclusion The study provides insights into the role of UDF in serving healthy and nutritional food to students for better health and improved academic performance. This work brings to light the relationship between students’ food choices and their impact on academic performance.

Assessment of Obesity Among Pregnant Women in the Volta Region of Ghana

Background: Obesity remains a rising challenge in both developed and developing countries, and maternal obesity has become one of the most occurring risk factors, which can lead to gestational diabetes, pre-eclampsia and prematurity in obstetric practice for both the mother and the child. Pregnancy is a timeline where obesity cannot be effectively worked on as the mother is more likely to live unhealthy lifestyle such as unhealthy diet, binge eating and less physical activity, which would most likely affect foetal health. This is an issue as most pregnant women in Volta Region are either overweight or obese. This research assessed the prevalence of obesity among pregnant women in the Volta Region of Ghana. Material and Method: A full structured questionnaire was administered to 220 participants based on their knowledge of obesity and its effect on pregnancy, food choices, mealtimes and portion sizes, as well as physical activity during pregnancy. Body weight and height were measured using standardized procedures and body mass index (BMI) was calculated. Overweight and obesity were defined based on WHO criteria. Data analysis was performed using SPSS version 20.0. Results: Based on excessive gestational weight gain, prevalence of obesity among the pregnant women was 54% (119). Majority of respondents had poor knowledge of obesity and its effect on the mother and the foetus, which represented a significant correlation (p&lt; 0.0001) between their caloric intake and high gestational weight gain. Physical activity showed no significant effect (p = 0.2) on gestational weight gain. However, pre-pregnancy BMI of the expectant mothers was directly linked to high gestational weight gain with age being the significant risk factor (p&lt;0.02) for obesity before pregnancy. Conclusion: This research found limited awareness of excessive gestational weight gain and its health consequences among pregnant women and the unborn baby. Therefore, monitoring gestational weight gain using diverse approaches to integrate and manage the condition in routine antenatal care needs consideration.

EXPRESS: How Socioeconomic Status Shapes Food Preferences and Perceptions

This paper assesses the extent to which consumers from the opposite poles of the socioeconomic distribution weigh three critical food attributes–healthiness, fillingness, and taste–, how they perceive the associations among them, and how differences in weights and associations influence food preferences. The results of a series of eight pre-registered studies in a highly unequal socioeconomic environment (Rio de Janeiro, Brazil) show that low (vs. high) socioeconomic status consumers are more likely to (a) choose unhealthy items even when supply-side factors (e.g., affordability and accessibility) are controlled by design, (b) trade healthiness for fillingness (but not taste), and (c) display stronger negative associations between the attributes (healthy = less filling; healthy = less tasty). These findings highlight the importance of a deeper understanding of the psychological differences in food preferences and perceptions and the use of such insights to design interventions aimed at mitigating nutritional inequality. In line with this rationale, the final set of studies shows that, albeit not being a trivial task, it is possible to increase healthy food choices among the disadvantaged by enhancing the fillingness of the healthy options available. Managerial and policy implications are discussed.

Comparing the Dietary Habits and the Food Choices Between Italian and Dominican Adult Populations: Focus on Fruit and Vegetable Intakes and Their Association with Skin Carotenoid Levels.

The Mediterranean Diet (MD) is characterized by a high intake of fruits and vegetables (FVs), which is considered as an important contributor to the beneficial effects of the MD pattern. In this cross-sectional study, we compared the food choices, evaluated by dietary habit questionnaires, of a sample of 995 adults, including 601 and 394 participants from Southern Italy and the Dominican Republic, respectively. In addition, we focused on their FV consumption, assessed by the Mediterranean Diet Adherence Screener (MEDAS) questionnaire, and on its association with skin carotenoid levels as measured by the Veggie Meter®. We found that a significantly higher percentage of Italians had five meals/day and breakfast compared to Dominicans (five meals/day: 43 vs. 25, p < 0.05; breakfast: 89 vs. 79, p < 0.05), whereas a lower percentage of participants from Italy consumed snacks between the two meals compared to the Dominican Republic population (47 vs. 70, p < 0.005). Most of the participants from both populations had breakfast at home. However, 59.3% of Italians and 27.5% of Dominicans (p = 0.005) had breakfast between 7:00 and 9:00 a.m., whereas 5.8% and 27.5% (p = 0.001) had breakfast after 9:00 a.m., respectively. Milk/yogurt and eggs were the most consumed foods for breakfast in Italy and the Dominican Republic, respectively. Regarding the main meals, most of the Italians and Dominicans had a first course for lunch and a second course for dinner. Of note, we observed that approximately half of the Italians ate FVs in their main meals and had a higher carotenoid score than the Dominicans. Interestingly, in the multiple linear regression analysis, we found that the carotenoid score was positively associated with sex (β = 0.078; p = 0.009), age (β = 0.008; p = 0.001), vegetable consumption (β = 0.12; p = 0.041) and the perception of a healthy diet (β = 0.12; p = 0.001) in the Dominic Republic population, while the carotenoid score was directly associated with sex (β = 54.97; p < 0.0001) and both vegetable (β = 25.42; p = 0.0008) and fruit (β = 38.61; p < 0.0001) consumption in the Italian sample. Our findings confirm the need to promote nutrition-based interventions to encourage FV intake, particularly in non-Mediterranean countries.

Sociodemographic Variations in Organic Food Consumption and Food Choice Motives among Malaysian Adults: A Study between Organic and Non-Organic Food Consumers

Sociodemographic Variations in Organic Food Consumption and Food Choice Motives among Malaysian Adults: A Study between Organic and Non-Organic Food Consumers

Stakeholder Perspectives on the School Food Environment: Insights from South African Learners-A Pilot Study.

Leveraging learner-driven insights to enhance the SFE can significantly influence food choices by decreasing the consumption of unhealthy foods and increasing access to healthier options. Using learners' voices as important stakeholders in the school food environment (SFE), this qualitative research study aimed to gain a deeper understanding of their perspectives, identify barriers and enablers to fostering a healthy SFE in South African public schools, and explore the link between the SFE and learners' food choices. Six focus group discussions (FGDs) with 4-6 participants were held in six schools, including three primary and three secondary schools in the KwaZulu-Natal Department of Education's iLembe district, SA, with learners aged 12-14 and 15-18 years, respectively. Learners were asked how schools could help them eat healthier and how their SFE benefitted them. The data were analysed using thematic data analysis methods. The FGDs generated 14 themes and subthemes. Emerging information suggests a lack of control over the sale of unhealthy food despite the existence of guidelines. This is further exacerbated by the marketing of unhealthy foods, which prevents learners from selecting healthier options. Furthermore, they stated that promoting the school food programme (SFP) and changing attitudes towards healthy food intake through comprehensive nutrition education are useful ways to enhance the SFE. The findings of this study underscore the critical role of learner insights in shaping effective strategies to improve the SFE.

Contextual factors influence food intake at eating occasions in young adults: A mixed effect analysis

Understanding eating behaviours of young adults is crucial for developing strategies to improve their diet quality. Factors that influence eating behaviours are often multifaceted and highly contextual, with little research focused on young adults. This study examined contextual factors influencing food intake at eating occasions among young adults. Participants (n = 675, 18–30 years) recorded dietary intake and contextual characteristics at eating occasions (n = 27,513) using a smartphone food diary (“FoodNow”) over three to four non-consecutive days. Food and beverage intakes were classified into six groups according to the Australian Dietary Guidelines. Eating occasion-level contextual factors, such as consumption location, purchase location, activity, and social context, were recorded via the app, while person-level contextual factors were collected through an online survey. Generalised mixed models with random intercepts were used to investigate effects of contextual factors on food group consumption at meals and snacks. Eating location was associated with vegetable and discretionary food intake; meals that were eaten while in transit were 0.59 serves lower in vegetables (95% CI: −0.93, −0.38; p < 0.001) and 0.31 serves higher in discretionary foods (95% CI: 0.03, 0.54; p = 0.014), compared meals eaten at home. Higher intakes of discretionary foods were observed when friends were present at meals and snacks (0.66 and 0.57 serves, 95% CI: 0.56, 0.88; 0.36, 0.77, p < 0.001). Meals purchased from convenience stores were higher in grain and discretionary foods than meals from other locations (p < 0.001). Majority of person-level factors showed minimal effects on food group consumption. Addressing factors such as purchase location and social contexts during meals and snacks may improve food choices, as small changes at eating occasions can significantly impact overall diet quality over time.

Disclosure of mandatory and voluntary nutrition labelling information across major online food retailers in the USA.

Nutrition labelling is mandatory on food products in retail stores, but compliance in the rapidly expanding online setting remains unclear. We assessed mandatory and voluntary labelling information across major U.S. online retailers. Between January and August 2022, we evaluated a representative basket of sixty food and beverage items across eight product categories of ten major retailers. We evaluated online presence, accessibility and legibility of four mandatory elements - Nutrition Facts, ingredients, allergen statements and percent juice for fruit drinks - and presence of seven voluntary elements - nutrient content claims, health/qualified health claims, ingredient claims, structure-function claims, additive claims, front-of-package nutrient profiling symbols and other marketing claims. Major online food retailers in the USA. N/A. On average, each mandatory element was present, accessible and legible for only 35·1 % of items, varying modestly by element (from 38·3 % for ingredients lists to 31·5 % for Nutrition Facts) but widely by retailer (6·6-86·3 %). Voluntary elements were present for 45·8 % of items, ranging from 83·7 % for marketing claims to 2·0 % for structure-function claims. Findings were generally consistent across the eight product categories. Voluntary elements were more frequently present than accessible and legible mandatory elements for six of ten retailers and seven of eight product categories. Mandatory nutrition label elements are not commonly present, accessible and legible in online retail settings and are less consistently present than marketing elements. Coordinated industry and regulatory actions may be needed to ensure consumers can access mandatory nutrition information to make healthy and safe food choices online.

Early influences on development of sensory perception and eating habits.

Infancy and early childhood are important periods for the development of food choices and eating preferences that are tracked into adult life influencing weight gain, body composition, metabolism, and ultimately affecting the balance between health and disease. In this narrative review, we aimed at discussing studies focused on the effects of fetal programming and early food experiences, highlighting recent advances in the discovery of factors that contribute to the development of food preferences and eating behavior. Food preference can be influenced by early direct contact with flavors, textures, and aromas, as well as by environmental adversities during early development. Evidence suggests that exposure to intrauterine growth restriction is associated with an increased preferences for highly palatable foods such as those rich in carbohydrates and fats over the life-course. Early flavor experiences, whether from amniotic fluid or human milk, may also shape the development of food preferences. Finally, children are more likely to accept textures that they are able to manipulate, and early exposure to a range of textures facilitates the acceptance of foods of various textures later on. Improving diet habits during gestation (fetal) and postnatal periods is of critical importance for the establishment of positive eating habits and healthy growth in infants and should be an important focus of primary prevention efforts.

Retrospective analysis of regional and metropolitan school food environments using Google Street View: A case study in New South Wales, Australia with youth consultation.

Food environments surrounding schools have a strong influence on the adolescent's food choices. Moreover, the prevalence of diet-related chronic diseases is higher in regional than metropolitan areas in Australia. Understanding school food environments in these different settings is crucial for informing future strategies to improve adolescent health. Google Street View was used to identify food outlets within 1.6 km around all secondary schools in Wagga Wagga and Blacktown in New South Wales which were selected as regional and metropolitan case study areas. Based on food outlet type, healthfulness categories were assigned, and Chi-squared tests were performed. The Health Advisory Panel for Youth at the University of Sydney (HAPYUS) were engaged to obtain their perspectives on findings. Unhealthful food outlets were consistently most prevalent around schools in Wagga Wagga and Blacktown over 17 years. In 2023, these were predominantly restaurants (19.4% vs. 21.1%), cafés (16.8% vs. 11.1%), fast-food franchise outlets (15.1% vs. 17.4%) and independent takeaway stores (14.1% vs. 9.6%). No significant difference in healthfulness between regional and metropolitan areas was found. Youth advisors recognised price and social reasons as major contributors to food choices. Google Street View was used as a novel resource to examine school food environments in regional and metropolitan areas which have remained consistently unhealthful for nearly two decades. SO WHAT?: Unhealthful school food environments may encourage poor diets and exacerbate rates of adolescent overweight and obesity. Critical government action is needed to improve school food environments.

Understanding consumer perception of a new product including apple pomace: The role of health, sustainability, and culinary engagement

The aim of the present study was to determine perception of a new product made with apple pomace including consumers from three different gastronomy cultures: Spain (Mediterranean), Poland (Central Europe), and Denmark (Nordic). The new product was mainly made from potato and apple pomace and had the typical texture of a savory snack (crisp-like), but it was characterized by its apple/sweet taste. Besides consumers from the aforementioned countries, a group of Foodies-consumers from 20 different nationalities participated in the study to determine potential differences on the product perception due to their high culinary knowledge/ingredients exposure. Over 600 consumers participated in the study. To segments consumers into different groups beyond nationality, the demographic questionnaire included the short version of the Food Choice Questionnaire, the Food Neophobia Scale, and questions on Dietary and Sustainability related habits. The hedonic response, as well as the intrinsic properties of the product (sweetness, sourness, saltiness, apple flavor, hardness, and crunchiness) were measured using Just-About-Right scales. Additional questions included assessment on the storytelling of the product, potential applications/consumption moments, and finally, the impact of adding a health (high in fiber) or a sustainable (made using by-products) claim. Analysis revealed variations in demographics across consumer groups, potentially influencing their perception of the new product. Including the question on applications/consumption moments of the new food, as well as gathering free words about the main aspects consumers valued about the food, were useful to better understand its potential in the market and design a proper communication strategy.

Positive perceptions and purchase of sustainable foods is associated with higher diet quality in Australian university students

Purpose This study aims to understand university students' perception and engagement with sustainable food practices and the relationship with diet quality. Design/methodology/approach A cross-sectional survey assessed Australian university students' sustainable food perceptions and purchasing behaviours, diet quality using the validated Australian Recommended Food Score and attitudes towards on campus sustainable food options. Findings Of respondents (n = 197; 63% female), over half (58%) perceived it was important to purchase sustainable foods. These students were eight times more likely report purchasing sustainable foods (OR: 8.1; 95%CI 4.2–15.7; SE: 0.3; p &lt; 0.001) and had significantly higher diet quality (Beta coefficient: 2.9; 95% Confidence Intervals 0.4–5.4; Standard Error: 1.3; p = 0.024). Students who reported frequently purchasing all types of sustainable foods, except organic foods, had significantly higher diet quality. Few students perceived there were sufficient sustainable food choices on campus (19%), but most supported the development of an edible campus (80%). Originality/value The results highlight the potential impact of promoting sustainable food options and creating a supportive campus food environment towards improving students’ diet quality.

NUTRIFLEX

The NUTRIFLEX project is a comprehensive AI-powered application designed to provide personalized nutrition and health management solutions. The goal of the project is to assist individuals in optimizing their diet based on their unique biological and emotional needs, including gut health, mood, and overall well-being. By combining artificial intelligence (AI) and user input, NUTRIFLEX offers tailored meal plans, calorie predictions, mood-enhancing food recommendations, and a gamified approach to motivate users to maintain a healthy lifestyle. The problem addressed by NUTRIFLEX is the growing challenge people face in maintaining a balanced and healthy diet. Modern lifestyles, characterized by fast-paced routines and unhealthy food choices, contribute to poor physical and mental health. Many individuals struggle to find the right balance between their nutritional intake and their health goals, whether it's weight loss, muscle gain, or general wellness. Furthermore, gut health, which plays a critical role in overall health, is often neglected in conventional meal planning applications. Mood fluctuations also significantly impact people's food choices, leading to stress eating or energy dips. NUTRIFLEX solves these problems by offering a holistic, AI-driven solution that adapts to users' unique needs. By using machine learning models, NUTRIFLEX predicts the calorie content of meals and creates personalized meal plans based on user-specific data such as Basal Metabolic Rate (BMR) and Total Energy Expenditure (TEE). The application also provides mood-based meal suggestions, helping users manage their emotional state through food choices that boost energy, focus, and relaxation. One of the most innovative features of NUTRIFLEX is its gut health functionality. By allowing users to input microbiome data, the app generates personalized meal recommendations designed to improve gut health, which in turn enhances overall physical and mental well-being. This focus on gut health distinguishes NUTRIFLEX from traditional meal planners. In addition, NUTRIFLEX integrates gamification to keep users engaged and motivated. Users can set health goals, track their progress, and earn rewards, making the health journey enjoyable and sustainable.

Organoleptic characteristics of high‐protein snacks with novel and sustainable ingredients: Cricket flour and carob powder

AbstractTo fulfill consumer trends in sustainable and healthy food choices, this study explored the application of edible insects and carob powder as sustainable and nutritious ingredients in developing a high‐protein snack, known as a protein ball. Four formulations were developed and characterized in terms of moisture content, water activity, color, texture, microbial count, and nutritional profile. Finally, the sensory profile was determined using the flash profile method, and the developed product was compared to a commercial product. The effect of replacing the conventional protein source with cricket flour and cocoa with its sustainable alternative, carob, on the measured characteristics was determined. The results showed that cricket flour significantly decreased the lightness color values (from 40 to 30) on the internal surface of the protein ball. Texture remained largely unaffected initially; however, after 2 weeks of storage, cricket flour significantly decreased the hardness (from 15 to 12 N) and chewiness values (from 1.6 to 1.0 N mm). Moreover, cricket flour significantly increased the aerobic count (from 3–4 log to 5 log cfu g−1). The sensory space of the cricket samples was separated from the milk protein samples, mainly related to flavor attributes, while the commercial sample was distinguished by dryness and sweetness. In general, carob powder did not affect the measured parameters compared to cocoa. This study demonstrated the suitability of utilizing cricket flour and carob powder in a high‐protein snack without substantially compromising the product's organoleptic properties. Future research could investigate the consumer acceptability of the product.

Molecular Survey of Parasitic Contamination of Frozen Berries.

Berries represent healthy dietary options and contain bioactive compounds associated with a decreased risk of diseases. Despite representing healthy food choices, these products can be contaminated by pathogenic microorganisms, including parasites. Among foodborne parasites, Giardia duodenalis, Cryptosporidium parvum, Cyclospora cayetanensis, Toxoplasma gondii, and Echinococcus multilocularis are of significant public health importance and have been recently detected in fresh berries in Europe, including Italy. Berries can be purchased fresh or frozen, and it is worrying that even frozen berries could represent a risk for the consumer. In fact, several parasites can resist freezing temperatures and have been responsible for outbreaks of infection. The aim of this study was to investigate the presence of G. duodenalis, C. parvum, C. cayetanensis, T. gondii, and E. multilocularis in frozen berries with simplex and multiplex real-time PCR protocols. A total of 108 packages of mixed frozen berries were bought from supermarkets located in a south-eastern region of Italy. The samples were tested using two simplex real-time PCR protocols targeting C. parvum and G. duodenalis, respectively, and a multiplex real-time PCR targeting C. cayetanensis, T. gondii, and E. multilocularis. None of the investigated parasites were detected in the frozen berry samples tested. This research topic is still unexplored and of great current interest. These results represent a first attempt to investigate parasitic contamination of frozen berries sold on the Italian market, but further large-scale surveys are required.

Who Would Taste It? Exploring Decision-Making Styles and Intention to Eat Insect-Based Food among Italian University Students

Background: Although insect-based foods (IBFs) have been recently proposed as a way to face climate crisis and starvation, they encounter aversion from Western countries, which express fear, disgust, and high risk. The contribution of psychology research to food choices highlights how decisions are made, not only through reasoned attitudes and goal-directed behavior, but also through more automatic associations (dual-system models). Methods: In this paper, we investigated people’s dispositions towards IBFs by combining (a) explicit attitudes (as assessed via self-report scales), (b) automatic associations (as measured via indirect measures), and (c) intention to taste, and comparing different profiles based on (d) psychological factors, including decision-making style, food neophobia, and trust in science and scientist. A pilot sample of 175 Italian university students participated in the study. Results: The analyses of the general sample highlighted rather negative attitudes. The cluster analysis identified 4 decision-making profiles: ‘the gut feeling’, ‘the suspicious’, ‘the vicarious’, and ‘the mind’. It revealed more favorable opinions in ‘the mind’ profile, characterized by a rational decision-making style and high trust in science, and very aversive reactions from ‘the suspicious’ profile, characterized by high food neophobia and low trust in science. Conclusions: The results underline the importance of psychological factors in interpreting people’s reactions to IBF and changes in dietary habits based on the decision-making process. They suggest possible strategies to promote eco-friendly diets.

Knowledge, attitudes and behavior of Gulf medical students in relation to Food Dome dietary guidelines: a mixed-method research

This mixed-methods research is the first to explore knowledge, attitudes and behaviours in relation to the Food Dome dietary guidelines (FDDG) among Gulf medical students. Quantitative phase included the administration of Food Dome questionnaire among n = 414 students; qualitative phase used focus group discussions. The quantitative findings show that more than half the sample reported that they had heard of the FDDG (55.3%), of which 15.7% followed and 39.6% did not follow the FDDG. An average female knew more about and behaved more in line with the guidelines, Bahrainis and Saudis were more aware than Kuwaitis on average, and those aged 21 or more showed, on average, more behaviour consistency with the FDDG. The qualitative findings show that the food choices of the Gulf medical students largely depend on time, university load, availability, and taste. Suggested recommendations include educational campaigns, FDDG application examples, teaching children from an early age.
