Background/Objectives: Rhinosinusitis (RS) is a prevalent inflammatory condition with substantial morbidity and variable response to standard therapies. Diet is a modifiable determinant of systemic inflammation, yet its role in sinonasal disease remains incompletely defined. Methods: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Scopus, Cochrane Library, and Web of Science were searched from inception through 28 June 2026. Studies assessing dietary exposures or interventions in RS were included using predefined criteria. Risk of bias was assessed using ROBINS-I and Joanna Briggs Institute tools. Due to heterogeneity in study design and outcomes, findings were synthesized narratively. Results: Ten studies met inclusion criteria (5 adult, 4 pediatric, 1 mixed), including interventional and observational designs. Anti-inflammatory dietary patterns were associated with improved sinonasal outcomes. In children, Mediterranean diet adherence reduced recurrent inflammatory episodes, and reduced sugar intake improved sinus infection scores with decreased TNF-α concentrations. In adults, both allergen-guided elimination diets and a low-arachidonic acid, low-salicylate, high-fiber dietary intervention improved symptom severity, with accompanying improvements in endoscopic outcomes. Observational studies demonstrated that higher fruit intake was associated with lower RS prevalence, whereas higher fat intake, caloric intake, Dietary Inflammatory Index scores, frequent meals prepared away from home, and ultra-processed food intake were associated with increased disease risk or sinonasal symptom burden. Phenotype-specific associations included increased dietary salicylate sensitivity and food-triggered symptom exacerbation among patients with nasal polyposis. Conclusions: Dietary patterns and specific nutritional exposures are associated with RS outcomes across age groups. Anti-inflammatory dietary profiles demonstrate potential protective effects, whereas pro-inflammatory dietary patterns are associated with increased disease burden. However, the predominance of observational data and study heterogeneity limit causal inference. Well-designed prospective and randomized studies are needed to define the therapeutic role of dietary modification in RS. Full article

Background: In the wake of the COVID-19 pandemic, the dietary landscapes of young adults have been profoundly reshaped. As social restrictions ease, the resurgence of dining out presents new behavioral shifts regarding health and safety. Objective: This study investigates the post-pandemic experiences of young adults in Hong Kong, focusing on the burgeoning phenomenon of eating out of home and its complex influence on eating habits and food hygiene consciousness. Methods: This qualitative study utilized a phenomenological approach to explore participants’ lived experiences. Semi-structured interviews were conducted with 12 young adults in Hong Kong to gather narratives regarding their dining practices. The data were analyzed using thematic analysis to identify recurring patterns associated with their return to public dining spaces. Results: Three core themes emerged: (i) confined palates: the remaking of the Hong Kong meal in the shadow of a pandemic; (ii) shared screen: mediating hunger from the home-as-hub; and (iii) watchful guard: the moralization of the meal amidst viral uncertainty. Conclusions: These findings dissect the critical, evolving relationship between contemporary consumption patterns and health maintenance. While the small size limits statistical generalizability, the study suggests that post-pandemic dining involves a modified reality of sustained hypervigilance. These insights offer a basis for developing sensitive and targeted public health strategies that resonate with the altered dietary realities of young adults in a post-pandemic world. Full article

The large-scale expansion of the golden jackal (Canis aureus) across Europe in recent decades has been strongly influenced by its successful space and habitat use. In this study, we analyzed the habitat selection of seven golden jackals tracked with GPS collars between 15 March 2021 and 25 November 2022 in a predominantly agricultural landscape in the southwestern part of the Pannonian Basin, Central Europe. Animals were tracked for an average of 29 weeks, and GPS collars recorded a total of 29,840 hourly localization points, which were compared to a high-resolution land cover dataset. We found that golden jackals maintain smaller home ranges in agricultural landscapes than in more pristine environments. Based on Jacobs’ index values calculated for monthly habitat preferences and the distribution of distances from land cover edges, we also found that preferences for the various habitat types differed significantly among individuals. Most of the time, golden jackals stayed near the edges of forests, agricultural lands, and shrublands, while they stayed away from artificial areas, wetlands, and water bodies. Forests and shrublands providing cover and safety were generally preferred by the golden jackals, especially during breeding and pup-rearing periods, while there was a strong avoidance of agricultural lands in general. Overall, our findings suggest that despite individual differences in the availability of habitat types within home ranges, forest–agricultural ecotones with relative proximity to food and shelter play a key role in the habitat selection of golden jackals.

At the beginning of the COVID-19 pandemic, people had to stay at home due to quarantine, and the food delivery industry grew significantly. Concerns have been raised regarding the popularity of away-from-home (AFH) meals and their impact on health. In this study, we evaluated the association between the frequency of AFH meals and the prevalence of allergic rhinitis (AR) and chronic rhinosinusitis (CRS). In this cross-sectional study, the Korean National Health and Nutrition Examination Survey was reviewed from 2010 to 2019. The frequency of AFH meals was assessed as how often the respondents ate AFH meals in an average week. Those who ate AFH meals less than once per week were designated as group 1, one to four times as group 2, and five times or more as group 3. The diagnoses of AR and CRS were evaluated, and symptoms, endoscopic findings, and serum immunoglobulin E (IgE) levels were assessed. Logistic regression analyses were performed. A total of 48,515 participants were eligible. In multivariate logistic regression analysis for AR, when compared to group 1, the odds ratios (ORs) for AR in participants of group 2 (OR = 1.226, 95% confidence interval [CI] = 1.136–1.324) and group 3 (OR = 1.227, 95% CI = 1.126–1.337) were significantly higher (p < 0.0001). For CRS, group 2 (OR = 1.139, 95% CI = 1.029–1.260) and group 3 (OR = 1.210, 95% CI = 1.078–1.358) showed a significantly higher risk than group 1 (p = 0.0044). Individuals who consume AFH meals frequently might suffer less from AR or CRS if they change their dietary habits and prepare meals more often at home. Full article

The Central Australian red honey-pot ant Melophorus bagoti maintains non-cryptic ground-nesting colonies in the semi-desert habitat, performing all the activities outside the nest during the hottest periods of summer days. These ants rely on path integration and view-based cues for navigation. They manage waste by taking out unwanted food, dead nestmates, and some other wastes, typically depositing such items at distances > 5 m from the nest entrance, a process called dumping. We found that over multiple runs, dumpers headed in the same general direction, showing sector fidelity. Experienced ants dumped waste more efficiently than naive ants. Naive individuals, lacking prior exposure to the outdoor environment around the nest, exhibited much scanning and meandering during waste disposal. In contrast, experienced ants dumped waste with straighter paths and a notable absence of scanning behaviour. Furthermore, experienced dumpers deposited waste at a greater distance from the nest compared to their naive counterparts. We also investigated the navigational knowledge of naive and experienced dumpers by displacing them 2 m away from the nest. Naive dumpers were not oriented towards the nest in their initial trajectory at any of the 2 m test locations, whereas experienced dumpers were oriented towards the nest at all test locations. Naive dumpers were nest-oriented as a group, however, at the test location nearest to where they dumped their waste. These differences suggest that in red honey ants, learning supports waste disposal, with dumping being refined through experience. Dumpers gain greater spatial knowledge through repeated runs outside the nest, contributing to successful homing behaviour. Full article

This study examined seafood consumption during the early period of economic recovery following the COVID-19 pandemic. Specifically, surveys of U.S. consumers compared seafood purchasing behavior of the first two quarters of 2021 (Q1, 1 January through 31 March 2021, and Q2, 1 April through 30 June 2021) with those of 2020. Each survey included 100 seafood consumer respondents in each of the 20 U.S. metropolitan market areas. Following data cleaning, there were 1885 valid responses for Q1-2021 and 1940 for Q2-2021. A majority (57%) of respondents had received at least one dose of the COVID-19 vaccine before March 2021 and 70% had received at least one dose as of June 2021. Regardless of vaccination status, few respondents (6% to 9.5% for food generally and 4% to 6.5% for seafood) reported changes in seafood consumption. Seafood consumption away from home increased significantly in Q1-2021 as compared to 2020 and continued to increase but to a lesser degree in Q2-2021. Demographic differences were found in shopping behaviors by age, education, income, and gender, but not by ethnic group. Generally, higher-income females with higher education tended to purchase more seafood. Respondents reported increased numbers of shopping trips per year in Q1-2021 as compared to 2020, which continued into Q2-2021 for general food, but shopping trips for seafood decreased as compared to 2020. The frequency of takeout purchases (times/year) of prepared meals for home consumption of seafood decreased during Q1 from 2020 and remained at that level in Q2-2021, but home delivery purchases of prepared meals of seafood increased during this period. Approximately 50–55% of respondents reported no change in overall seafood consumption levels, while 28% noted an increase in seafood consumption compared to pre-pandemic periods, a significant increase from the 19% who had reported doing so pre-pandemic. In contrast, those reporting a decrease declined from 31% to 17% in comparison to pre-pandemic levels. Seafood consumption in the U.S. remained stable and recovered in early 2021, with a preference for dining out. Consumer behaviors varied by age, income, education, and gender, but not by ethnicity. These changes were primarily driven by access, availability, and income, indicating the need for further research on long-term consumption patterns. This study found apparent stability of seafood consumption by U.S. consumers, which recovered from pandemic consumption levels in early 2021, and there was little change in seafood consumption, frequency, or the types of seafood consumed. Vaccination status did not appear to affect seafood consumption. Full article

Hybrid methods are a suitable option for extracting dietary patterns associated with health outcomes. This study aimed to identify the dietary patterns of Brazilian adults (20–59 years old; n = 28,153) related to dietary components associated with the risk of obesity. Data from the 2017–2018 Brazilian National Dietary Survey were analyzed. Food consumption was obtained through 24 h recall. Dietary patterns were extracted using partial least squares regression, using energy density (ED), percentage of total fat (%TF), and fiber density (FD) as response variables. In addition, 32 food groups were established as predictor variables in the model. The first dietary pattern, named as energy-dense and low-fiber (ED-LF), included with the positive factor loadings solid fats, breads, added-sugar beverages, fast foods, sauces, pasta, and cheeses, and negative factor loadings rice, beans, vegetables, water, and fruits (≥|0.15|). Higher adherence to the ED-LF dietary pattern was observed for individuals >40 years old from urban areas, in the highest income level, who were not on a diet, reported away-from-home food consumption, and having ≥1 snack/day. The dietary pattern characterized by a low intake of fruits, vegetables, and staple foods and a high intake of fast foods and sugar-sweetened beverages may contribute to the obesity scenario in Brazil.

(1) Background: Independently owned restaurants (IORs) are prevalent in under-resourced racial and ethnic minority communities in the US and present a unique setting for public health nutrition interventions. (2) Methods: We conducted 14 in-depth interviews with IOR owners in Baltimore about their perceptions of healthy food, and customers’ acceptance of healthier menus and cooking methods and concurrent observations of the availability of healthy options on their menus. Qualitative data were coded and analyzed using ATLAS.ti. Observations were analyzed with statistical analysis performed in R. (3) Results: Owners perceived non-fried options, lean proteins, and plant-based meals as healthy. While open to using healthier cooking fats, they had mixed feelings about reducing salt, adopting non-frying methods for cooking, and adding vegetables and whole grains to the menu, and were reluctant to reduce sugar in recipes and beverages. Only 17.5% of 1019 foods and 27.6% of 174 beverages in these IORs were healthy, with no significant differences in the healthfulness of restaurant offerings within low-healthy-food-access/low-income neighborhoods and those outside. (4) Conclusion: Healthy options are generally scarce in Baltimore’s IORs. Insights from owners inform future interventions to tailor healthy menu offerings that are well-received by customers and feasible for implementation. Full article

This paper examines the social context of “domestic food production” (dfp) in the inland North of Sweden, with a focus on understanding the contributions of non-commercial food distribution to local food security and sustainable rural community-building. We report on the findings of an exploratory pilot study that included an online survey of 305 people who engaged in at least one dfp activity (hunting, fishing, foraging, or farming). The aims were to uncover common social practices of dfp, as well as to identify key values attached to dfp, the extent of commercial and non-commercial distribution of home-produced food, and motivations to give away food. The main findings emphasize the social nature of dfp activities, with the vast majority of respondents undertaking dfp in groups or as part of formal clubs. Key values attached to dfp included social and community-related aspects, while commercial interests were limited. Respondents were more likely to engage in non-commercial distribution networks, usually involving close family and friends. Food givers mostly cited social factors as their main motivations rather than other food-related aspects (such as food security, health benefits, or food waste). Food givers were also likely to receive food from others, emphasizing the relatively narrow and reciprocal character of non-commercial food networks. We conclude that non-commercial dfp networks may be expanded to the broader community by exploiting the social nature of dfp and encouraging generalized reciprocity led by dfp clubs. This could potentially reduce the negative impacts of food deserts whilst also stimulating community interactions, learning and local dfp communities of practice. Full article

Consumers’ perception plays a central role in tackling food waste at the final consumption stage, specifically among university students. In Europe, it is estimated that 47 to 67 Mt of food waste is generated at the household level or at food service consumption, including university canteens. The present cross-country research, through an online-based questionnaire among university students, investigates students’ perception on food waste by distinguishing among two different categories: on the one side, students living with their family; on the other side, students living without their family. Further, the research distinguishes among students eating at university canteens, students preparing food at home, students purchasing take-away foods and students coming back home to eat. The study compares university students’ perception on food waste in Italy and in Poland, with the overarching purpose of shaping sustainable pathways and defining educational interventions to enhance students’ perception and awareness on food waste. Data are analyzed according to the Mann–Whitney U test and the Kruskal–Wallis test. Age is a pivotal factor and suggests a generational gap in awareness and attitude toward food waste, whereas sex significantly affects food waste perception in Poland but not in Italy, suggesting a more homogeneous perception across sexes. The research highlights the impacts that socio-economic and environmental crises (e.g., climate change, the Russia–Ukraine conflict, high inflation rates) have on food waste perception in Poland, which is closer to that of Russia and Ukraine compared to that of Italy, and provides academics, practitioners and public authorities with practical and theoretical insights toward food waste minimization.

In highly developed countries, more and more people use culinary services. Cooking at home, for the family, is giving way to culinary services. Consumers either order food home or use the offers of restaurants and bars. Consumers’ choice of culinary form may be influenced by cooking television programs. Many TV stations broadcast cooking programs. This study examined the impact of television culinary programs on consumer behavior in the restaurant services market. The article examines the interplay of emotional responses, personality traits, and culinary preferences to understand how TV cooking programs influence dining decisions. The study was conducted using the CAWI method, which involved 742 respondents. The study, conducted between May 2021 and April 2022, was addressed to people who visited restaurants presented in the Polish culinary TV show titled “Kitchen Revolutions”. The study revealed that almost 3/4 of the respondents chose restaurants based on the program’s recommendations. Although there was a strong emotional connection with this program—nearly half of the respondents expressed delight in the taste of snacks and main courses—this did not always translate into an increased frequency of eating meals away from home. Only every third respondent said that the program influenced their gastronomic behavior. The research hypotheses examined the extent to which culinary TV shows influence the frequency of visits to restaurants, the perceived quality of life, and the influence on consumers with specific personality traits. The results partially supported the hypothesis that cooking programs on television encourage people to eat out more often, but the perceived impact on quality of life and on some personality traits was less clear. The article contributes to the understanding of consumer behavior in the food service market by highlighting the complex dynamics of emotional reactions, personality traits, and the impact of culinary television programs. The findings have practical implications for the restaurant industry, suggesting a focus on emotional impact, food quality and presentation, and targeting marketing strategies towards consumers who are open to new experiences and ready to experiment.

The loss of productive soils and food-producing landscapes on the edges of cities is an increasing issue facing Aotearoa New Zealand. Like many countries globally, New Zealand’s largest cities are facing rapid expansion because of increasing urbanisation, with high levels of low-density residential sprawl into the productive peri-urban hinterlands and increasing rates of ‘reverse sensitivity’. Food production, as a result, is being pushed further away, disconnected from the communities it serves, and often onto less productive soil. This paper explores the perceptions and attitudes of both peri-urban residents and food producers living and working within the peri-urban zone of Ōtautahi Christchurch. Conducting two surveys, one with residents and another with producers, respondents’ perceptions of food growing within this peri-urban landscape are explored to better understand the enablers and barriers of growing food close to cities. Overall, the results indicated that peri-urban residents appreciate food being produced close to where they live, with over 90% of residential respondents feeling either ‘mostly positive’ or ‘extremely positive’ towards food being grown close to their homes. Of greatest concern for peri-urban residents were issues relating to negative impacts on the environment and human health, with particular concern for water quality. The lack of accessibility to locally produced food was also identified as an area of concern to residents. Food producers felt less positive towards operating their food-production enterprises within the peri-urban zone, identifying a range of issues impacting their experience. The information rendered from these surveys provides a base for future land-use planning consideration within the peri-urban zone, where both food production and housing can co-exist. Full article

Concern for the environment when making dietary choices has grown as the contribution of the food sector to global greenhouse gas emissions becomes more widely known. Understanding the correlates of beef eating could assist in the targeting of campaigns to reduce the consumption of high-impact foods. The objective of this study was to identify the demographic, socioeconomic, and behavioral correlates of disproportionate beef consumption in the United States. We analyzed 24-h dietary recall data from adults (n = 10,248) in the 2015–2018 National Health and Nutrition Examination Survey (NHANES). Disproportionate beef consumption was defined as an intake greater than four ounce-equivalents per 2200 kcal. Associations of this indicator variable with gender, age, race/ethnicity, education, family income, diet knowledge, and away-from-home meals were assessed using logistic regression, incorporating survey design and weighting. Disproportionate beef diets were consumed by 12% of individuals, but accounted for half of all beef consumed. Males were more likely than females (p < 0.001) to consume these diets. This relationship was seen in all bivariate and multivariable models. Older adults, college graduates, and those who looked up the MyPlate educational campaign online were less likely (p < 0.01) to consume a disproportionate beef diet. While almost one-third of reported consumption came from cuts of beef (e.g., steak or brisket), six of the top ten beef sources were mixed dishes: burgers, meat mixed dishes, burritos and tacos, frankfurters, soups, and pasta. Efforts to address climate change through diet modification could benefit from targeting campaigns to the highest consumers of beef, as their consumption accounts for half of all beef consumed.

The assessment of eating and physical activity habits is an important step in promoting healthy behaviors among the adolescent population and is key in the prevention and management of chronic non-communicable diseases, such as obesity, diabetes, and cardiovascular disease. For this purpose, reliable and valid measuring instruments are essential. In this context, the aim of this article is to present the validation of a self-report questionnaire on eating and physical activity habits among adolescents in Mexico City. In order to validate the questionnaire, a cross-sectional study was conducted with a sample of 2710 adolescents between 11 and 12 years of age, the piloting of the questionnaire was carried out in September 2022 with a focus group, and the programming of the anthropometric measurements was established with the Federal Educational Authority of CDMX, as well as the application of the questionnaire to 33 schools, with these activities being scheduled from 7 November 2022 to 3 February 2023 and having an application duration of 15–25 min for each of the groups to which it was applied; the questionnaire that was applied consists of 31 questions that refer to the frequencies, quantity, or performance of behaviors related to the frequency and type of food, type of physical activity and behaviors related to the act of eating referring to the place where it is carried out (home or away from home) and with whom it is carried out (alone or in company), and about the individual’s lifestyle. Subsequently, the reliability of the instrument was evaluated using Cronbach’s alpha coefficient, and an exploratory factor analysis was conducted to determine the structure of the questionnaire. The results obtained showed that the questionnaire was adequately reliable (α = 0.778) with an eight-factor structure: four questions on mealtime frequencies, four questions on physical activity and lifestyles, six questions on the consumption of high-calorie foods, four questions on company and food consumption, four questions on the consumption of vegetables and fruits, four questions on the place of food consumption, two questions on the consumption of alcoholic beverages, and three questions on the consumption of sugary drinks, plain water, and milk. In conclusion, the self-report questionnaire on eating and physical activity habits among adolescents in Mexico City is reliable, has adequate internal consistency, and can therefore be used as a useful tool for the evaluation of eating and physical activity habits in this population.

Background: The years spent at university represent a critical period that can influence both the quality of lifestyle and the eating habits of subsequent adulthood, and also, in the long term, the health of the individual. The aim of this study was to investigate the lifestyle of university students living away from home. Methods: Each subject recruited for the study was given a questionnaire to obtain general information, eating habits and physical activity levels before (T0) and after six month of training seminars (T1). Blood pressure, body composition and questionnaire responses were investigated. Results: The main findings of this study are a significant decrement in blood pressure; an increment in physical activity practice; an increased number of subjects who pay attention to the calorific value of food and also an improvement in BIA parameters. Conclusions: In conclusion, this study demonstrated the challenges that university students face in leading a healthy lifestyle and caring for their nutritional needs, particularly when they are away from their families. No intervention specifically targets young adults, even though much emphasis is placed on the promotion of a healthy lifestyle based on a varied and balanced diet and sufficient exercise. Our study showed that it is possible to improve lifestyle through educational events aimed at making students aware of the health risks deriving from unhealthy lifestyles. Full article
