Background/Objectives: With the rising trend of out-of-home dining in China, the use of iodized salt (IS) in eating-out venues plays a key role in preventing iodine deficiency disorders (IDDs). However, the coverage rate of iodized salt (CRIS) and the utilization rate of adequately iodized salt (URAIS) in these venues in China remain underexplored, potentially undermining IDD prevention strategies. This study aims to assess the CRIS and URAIS in such venues across China and identify the factors influencing their prevalence. Methods: From 2021 to 2024, a nationwide cross-sectional study was conducted in China, involving 19,346 venues. A 50 g sample of cooking salt was collected from each venue, and the iodine content was measured. The CRIS and URAIS were calculated, and associations with various factors were assessed using Chi-square tests, the Cochran–Armitage trend test, and multivariate logistic regression. Results: Of the 19,346 samples, 18,519 tested positive for IS, and 17,588 contained adequately iodized salt (AIS), resulting in a CRIS of 95.7% and a URAIS of 90.9%. Significant regional differences were found, with coastal areas showing a lower CRIS and URAIS than inland areas (87.0% vs. 97.8%; 81.0% vs. 93.2%) and urbanized areas having lower rates compared to less urbanized areas (94.1% vs. 97.3%; 88.9% vs. 92.9%). Higher per capita income was associated with a lower CRIS and URAIS (Z = −19.72, p < 0.0001; Z = −13.85, p < 0.0001). Lower per capita income (OR = 3.24, OR = 1.36, p < 0.0001), inland areas (OR = 4.14, OR = 2.68, p < 0.0001), and mountainous areas (OR = 2.48, OR = 1.27, p < 0.0001) were associated with a higher likelihood of IS and AIS use. Conclusions: While the CRIS and URAIS in dining venues meet national standards, regional disparities persist, particularly in coastal, plain, and economically advanced areas. Strengthening regulatory oversight and public education on iodized salt’s health benefits is essential. Full article

Background/Objectives: Food allergy (FA) is a growing concern in pediatric care, requiring effective avoidance strategies and timely emergency responses. The role of caregivers is central to the daily management of FA. This study aimed to assess parental knowledge, preparedness, and behaviors regarding pediatric FA management, focusing on both prevention and emergency readiness. Methods: A cross-sectional survey was conducted from December 2024 to April 2025 through the SurveyMonkey^® platform, promoted by the Italian Society of Pediatric Allergology and Immunology (SIAIP). The anonymous, structured questionnaire was distributed online and in two Italian university hospitals. A total of 129 fully completed responses from caregivers of children with FA were analyzed. The survey explored self-perceived knowledge, symptom recognition, preventive actions, emergency preparedness, and communication practices. Results: Only 9.3% of parents considered themselves “very informed,” while 54.3% reported limited or no knowledge. Just 16.0% recognized all symptoms of an allergic reaction, and only 24.0% could distinguish mild reactions from anaphylaxis. Notably, 67.4% reported not knowing how to respond to anaphylaxis, and 83.7% did not possess an epinephrine auto-injector. Preventive measures at home were inconsistently applied, and 41.1% took no precautions when eating out. Communication with external caregivers was often informal or absent. Only 33% updated physicians regularly. Conclusions: The findings reveal significant gaps in parental preparedness and highlight critical areas for educational intervention. Enhanced caregiver training, standardized communication protocols, and improved clinical follow-up are essential to strengthen pediatric FA management and safety. Full article

Background: Food environments can determine food choices, acting as barriers to or promoters of healthy eating. It is necessary to investigate individuals’ perceptions of those barriers and promoters of healthy eating in the food environment. Methods: This is a qualitative and quantitative study involving patients diagnosed with arterial hypertension. In the quantitative approach, a validated questionnaire for the Brazilian population, the Perceived Nutrition Environment Measures Survey, was used. For the qualitative approach, a talking map was applied in a focus group with guiding questions. Quantitative data were analyzed through simple relative frequency, and qualitative data through reports; subsequently, both were grouped into perceived barriers and facilitators. Results: Participants found high access to ultra-processed foods, strongly influenced by advertising in commercial establishments, as a barrier, as well as barriers related to changes in commensality habits and transformations in food systems. As promoting factors, access to fruits and vegetables was highlighted as favoring healthier food choices. The qualitative findings emphasized the importance of home gardens and foods sourced from family farming. Conclusions: This study found that individuals perceive high access to ultra-processed foods in their food environment, both in financial terms and availability, while reporting low access to fresh foods.

Background/Objectives: Imposed sleep restriction leads to increased feelings of appetite and hedonic eating behaviors (or food rewards). No study to date has assessed home-based measures of sleep with appetite and food rewards exclusively in Black emerging adults (ages 18–28 years), despite higher risks of short sleep and obesity in this population. We examined associations between 6-month changes in sleep with changes in appetite and food reward in Black emerging adults. Methods: Fifteen Black emerging adults (12 females; age, 21 ± 2.5 years; body mass index, 25.7 ± 4.5 kg/m²; body fat, 25.8 ± 11.9%) completed two identical 7-day measurement bursts at baseline and 6 months. Sleep (duration, efficiency, and architecture) was captured via 7 days of actigraphy and 2 nights of in-home polysomnography. During a laboratory visit, participants completed appetite measures (desire to eat, hunger, fullness, and prospective food consumption) via visual analog scales before and for 3 h following standard breakfast intake. The food reward for the fat and sweet categories of food was measured before lunch with the Leeds Food Preference Questionnaire. Results: Fasting fullness scores decreased from baseline to 6 months (−8.9 mm, p < 0.01) despite increases in body weight (2.6 kg, p < 0.01) and waist circumference (2.4 cm, p = 0.03). Increases in actigraph-measured sleep duration were associated with decreases in fasting desire to eat (r = −0.58, p = 0.04). Increases in actigraph-measured sleep efficiency were also associated with decreases in explicit liking for sweet foods (r = −0.60, p = 0.03). Conclusions: Our findings suggest that improvements in sleep duration and sleep efficiency may lead to decreased feelings of appetite and food reward in Black emerging adults. Full article

The COVID-19 pandemic had significant global impacts. In Japan, consumers refrained from going out, and dining out decreased significantly, which strongly affected the restaurant industry and resulted in a shift in food demand from eating out to home consumption. The seafood industry is no exception to this trend. This study surveyed 300 individuals with experience in seafood transactions across wholesalers, restaurants, and retailers to examine how the pandemic influenced supply and demand patterns from a distribution perspective. Results indicated that while the volume of luxury seafood handled by restaurants and wholesalers decreased, the volume handled by retailers increased. Conversely, the volume of inexpensive popular seafood declined across all three sectors. The findings suggest that some of the luxury seafood previously sold to restaurants was redirected to retailers as consumer demand shifted from dining out to home consumption during the pandemic.

The consequences of climate change directly affect food production and threaten food security. Therefore, efforts are needed to reduce environmental impacts while ensuring access to food. Massive food services play a key role in this context; however, related literature lacks comparative studies between home cooking and restaurants. Through life-cycle assessment, this research compares the environmental impacts generated by stewed chickpeas, a nutritious and flavorful meal prepared at a large food service offered by a public university, and those prepared at home using two recipes. The system boundaries consider the impact of ingredient production, processing, cooking, cooling, and reheating, as well as waste and wastewater generation. The functional unit (FU) weighs 100 g to facilitate comparison. The findings indicate that the recipe from the massive food service has a significant impact on human health, resulting in 3.54·10⁻⁷ DALY; meanwhile, the other two scenarios generate approximately 7.2·10⁻⁷ DALY. Moreover, regarding biodiversity impact, the recipe from the massive food service reaches 8.57·10⁻¹⁰ species.yr; by contrast, the other scenarios generate around 1.01·10⁻¹⁰ species.yr. Massive food services exhibit a lower environmental impact than home meals in preparing stewed chickpeas. This difference is primarily attributed to the cooling and reheating stages that occur when eating outside the home. Full article

People in multilingual societies develop complex and interconnected food-making and food-discussing networks. On the basis of an experimental course titled “Food at Home, Food on the Move: Globalization and Regionalism in Modern Food Culture” taught at the University of Helsinki, we will show how the acquisition of culinary terminology puts forward the interconnectedness of languages and the dynamics between them in several sociolinguistic contexts. The lectures were grouped geographically: Eating with the Neighbors (Finnish cuisine and Swedish, Russian, Karelian and other influences); From the Baltic to Central Europe (Latvian, Lithuanian, Polish, German, and Hungarian food cultures); Formative Cuisines of the Mediterranean (French, Italian, Greek, Middle Eastern cuisine, etc.); and Eating Outside Europe (food culture influences from the US, Mexico, China, Japan, and India). The assignments included a critical lecture diary, an essay about eating experiences, or additional reading, a conversational analysis of a culinary show, or fieldwork in an ethnic restaurant. Raising awareness of linguistic and cultural diversity, motivating course participants to discuss the role and interaction of languages in their repertoire, makes them reflect on their multilingual identities. It allows educators to explore individuals’ DLCs in different contexts while navigating diverse global and local environments based on the principles of fairness and equality in education.

Background/Objectives: Despite the growing awareness of nutrition and the popularity of healthy lifestyles among adolescents, disordered eating behaviors—such as anorexia nervosa, bulimia nervosa, binge eating disorder (BED), and avoidant/restrictive food intake disorder (ARFID)—remain significant public health concerns. ARFID, officially recognized only in 2013, is still poorly understood among youth. This study aimed to assess the relationship between adolescents’ nutritional knowledge, emotional regulation, media influence, and eating behaviors. Methods: A cross-sectional study was conducted in 2024 among 120 students aged 15–17 attending W. Reymont Secondary School No. II in Ostrów Wielkopolski, Poland. Participants completed a custom-designed, paper-based questionnaire consisting of 30 single-choice questions and demographic items. The instrument assessed knowledge of eating disorders, body satisfaction, social media impact, and the emotional determinants of food choices. The tool was developed with expert input but has not undergone formal psychometric validation. While many adolescents demonstrated basic nutritional knowledge—such as awareness of BMI norms and food group distribution—they often failed to apply this knowledge to their dietary behaviors. Results: Significant gender differences were observed: girls were more likely to restrict food intake, report emotional eating, and engage in slimming behaviors, while boys were less emotionally reactive and less influenced by social media. Most participants reported eating one meal daily with family but rarely discussed nutrition at home. Emotional involvement in eating, particularly among girls, emerged as a key factor, more influential than social media in shaping dietary behaviors. Conclusions: The findings highlight a clear gap between nutritional knowledge and actual behavior among adolescents, driven in part by emotional dysregulation and body image concerns. School-based interventions should incorporate not only nutritional education but also emotional regulation strategies and media literacy to effectively support healthy eating behaviors in youth.

Background/Objectives: Recent decades have seen a remarkable westernization of diets and a decline in adherence to the Mediterranean diet (MD). This study examined the eating habits of a representative sample of Italian university students to identify the determinants of adherence to the MD and the most relevant actions to improve their well-being. Methods: The Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) and Sustainable Healthy Diet (SHED) index questionnaires were used to explore MD adherence as the primary outcome, and dietary behavior sustainability, respectively. Sociodemographic, anthropometric, and lifestyle information was also collected. Results: The final sample included 1434 subjects (18–24; 60% female). The median (IQR) KIDMED score was 6.0 (4.0–8.0) and 33% showed a high adherence to the MD. Having breakfast, eating fruit and vegetables at least once a day, consuming pasta or other grains almost daily, and using olive oil at home were among the most common positive aspects of students’ diets. However, regular consumption of fish, nuts, legumes, dairy products, and a second serving of fruit and vegetables was less prevalent. Having an active lifestyle, eating more plant products, and having more sustainable dietary behaviors in terms of the SHED index, were the main determinants of a high KIDMED score. Likewise, graduate students, daily consumers of plant-based meat alternatives, and students attending university canteens daily were more likely to adopt healthier diets. Conclusions: Future actions are crucial to create a food environment that facilitates healthy and sustainable dietary choices among young adults, such as improving the nutritional quality of processed products and regulating their promotion, as well as implementing initiatives to improve university food services and encourage the use of campus dining facilities.

The objective of this study is to analyze the current situation of out-of-home catering (OHC) in Germany concerning the use of regional organic food using a case study; we also aim to determine the potential and challenges that exist in increasing the proportion of regional organic food in OHC. The food purchasing data from three canteens of the company were analyzed concerning regionality, seasonality, and organic share. The companies’ employees were asked about their willingness to pay and their attitude towards regional organic food using an online questionnaire. A price comparison between organically and conventionally grown food was carried out with food wholesalers’ product price lists. The study confirms the potential to increase the share of regional organic food in OHC. With their private purchasing behavior, eating habits and willingness to pay a surcharge for organic quality in the company restaurants, the consumers confirm that they support an increase in the regional organic share. Regional organic food could be purchased from (organic) wholesalers. However, the study also shows that the cost of sourcing organic food is on average 50% higher than that of conventional food and that this price markup is the main reason for consumers not buying organic food.

Food neophobia (FN) has been poorly explored in real contexts and in large-scale studies with children. This study assessed the impact of FN in children on school canteen meals by considering liking, emotional status, and food waste behaviours. We involved 630 children (7–11 years old; females = 53%) from nine Italian primary schools. The main self-reported variables that were collected included pleasure of eating in the canteen, declared liking for different foods, emotional responses, meal description, and food waste. The characteristics of low neophobia (LN), medium neophobia (MN), and high neophobia (HN) were comparable between genders and provenience and did not differ by the pleasure of eating at home. Children with HN had the lowest frequency of eating in the canteen, the highest self-reported amount of wasted food, and the lowest liking for all items, especially vegetables and legumes; they selected mostly emotions with negative valence and described the meal as more uncomfortable and boring. Instead, children exhibiting LN used positive emotions with high arousal to describe the meal and found it a little boring, while those with MN showed an intermediate attitude. Children with HN may benefit from familiarisation actions to accept non-domestic meals and reduce food waste in non-familiar environments. Improving school canteen contexts (e.g., the socialising possibility) can modulate children’s emotional responses and reduce food waste. Full article

Background: Culinary habits and knowledge play a key role in shaping dietary behaviors and overall health. In Spain, societal changes have led to a decline in traditional Mediterranean practices and, in some cases, to unhealthy lifestyles. This study explores the relationship between culinary habits, knowledge, and health behaviors among adults in Spain. Methods: A cross-sectional study was conducted with 1534 participants using validated questionnaires to assess culinary habits, knowledge, and lifestyle factors. Data were collected online via snowball sampling and analyzed using the Kruskal–Wallis test and a Gaussian graphical model to explore variable associations. Results: Participants with healthy culinary habits reported higher self-perceived health and greater fruit and vegetable consumption, while those with unhealthy habits consumed more fast food. Higher culinary knowledge was linked to better dietary choices, more vegetables and cereals, and lower smoking rates. Higher home cooking frequency was moderately correlated with the use of healthy cooking techniques. The network analysis showed that the frequency of cooking at home is positively associated with gender and age. A similar association was found for time spent cooking. Positive associations were also found between living with the family and time spent cooking, while age showed a negative correlation with living situation. Centrality measures identified influential variables within the network. Conclusions: Culinary knowledge and habits strongly influence health behaviors. Network analysis underscores the importance of specific variables such as cooking frequency and living situation in shaping lifestyle patterns. Educational programs aimed at enhancing culinary skills could promote healthier eating behaviors and mitigate public health risks. Full article

Background: Participation in home and wild food procurement (HWFP) activities (i.e., gardening, hunting, fishing, foraging, preserving food, raising livestock, and raising poultry for eggs) skyrocketed during the COVID-19 pandemic. Procuring food through HWFP activities may have important food security and nutrition benefits, while also enhancing food sovereignty and food system resilience. This cross-sectional study examined the effect of HWFP activities on food security status, fruit and vegetable intake, and meat consumption. Methods: We used data collected in 2021 and 2022 from adults (n = 2001) through two statewide representative surveys in Maine and Vermont, United States. Dietary intake was assessed using the Dietary Screener Questionnaire. Food security status was assessed using the U.S. Department of Agriculture’s 6-item short-form food security module. We analyzed the data using linear regression, logistic regression, and ordinal logistic regression models. Results: Sixty-one percent of respondents engaged in HWFP activities; the majority of those gardened. Households engaging in most individual HWFP activities had greater odds of being food insecure. HWFP engagement was positively associated with fruit and vegetable consumption. Specifically, gardening was associated with an additional one cup-equivalent in fruit and vegetable consumption per week compared to respondents that did not garden. Furthermore, when exploring these relationships disaggregated by food security status, we find that this effect is stronger for food insecure households than food secure households. Respondents from households that hunted were more likely to eat wild game meat and also consumed red and white meat more frequently compared to households that did not hunt. Conclusions: Overall, our results indicate potential nutrition and food security benefits from engaging in HWFP activities. Future research should continue to examine a full suite of HWFP activities and their relationship to diet, health, food security, and food sovereignty. Full article

It is now known that diet or food is one of the environmental factors that can induce or contribute to autoimmunity. In a healthy person with a normal functioning immune system, food substances encounter no resistance and are allowed passage through the immune barriers without triggering immune reactivity. However, clinicians are becoming increasingly aware that modern food-processing methods can increase or decrease the immune reactivity of foods, including allergic reactions. Immune reactions to undigested food antigens could result in the production of IgE antibodies, which are involved in immediate immune reactivity, and in IgG and IgA antibodies, which are involved in delayed immune reactivity. Currently, measurements of these antibodies are generally only performed against antigens derived from raw foods. However, testing for food reactivity based only on raw food consumption is inaccurate because people eat both raw and cooked foods. Even home-cooked foods undergo different kinds of preparation or processing. Food processing can change the structure of raw food materials into secondary, tertiary, and quaternary structures that can have different reactive properties. This can affect the body’s normal oral tolerance of food, causing the immune system to mistakenly identify food as a harmful foreign substance and react to it immunologically, leading to food immune reactivity. This abnormal reaction to food molecules can lead to the production of antibodies against not just target food antigens but also the body’s own tissues, which can have significant implications in autoimmunity induction due to cross-reactivity and the other mechanisms discussed here. We hope that this present review will stimulate further research on the role of modified food antigens in the induction of autoimmunity based on some or all of the key points discussed in this review.

Background/Objectives: Sleep is a fundamental physiological function that plays a crucial role in maintaining health and well-being. The aim of this study was to assess dietary and lifestyle factors associated with adequate sleep duration in children and adolescents living in five Mediterranean countries. Methods: Parents of children and adolescents taking part in an initial survey for the DELICIOUS project were examined to assess their children’s dietary and eating habits (i.e., meal routines), as well as other lifestyle behaviors (i.e., physical activity levels, screen time, etc.) potentially associated with adequate sleep duration (defined as 8–10 h according to the National Sleep Foundation). The youth healthy eating index (Y-HEI) was used to assess the diet quality of children and adolescents. Multivariate logistic regression analyses were performed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs), indicating the level of association between variables. Results: A total of 2011 individuals participated in the survey. The adolescents and children of younger parents reported being more likely to have inadequate sleep duration. Among eating behaviors, having breakfast (OR = 2.23, 95% CI: 1.62, 3.08) and eating at school (OR = 1.33, 95% CI: 1.01, 1.74) were associated with adequate sleep duration. In contrast, children eating alone, screen time, and eating outside of the home were less likely to have adequate sleep duration, although these findings were only significant in the unadjusted model. After adjusting for covariates, a better diet quality (OR = 1.63, 95% CI: 1.24, 2.16), including higher intake of fruits, meat, fish, and whole grains, was associated with adequate sleep duration. Conclusions: Adequate sleep duration seems to be highly influenced by factors related to individual lifestyles, family and school eating behaviors, as well as diet quality. Full article
