Background: Schools are widely recognized as key settings for promoting healthy eating behaviors and supporting childhood obesity prevention. In recent years, increasing attention has been devoted to experiential and interactive nutrition education strategies designed to actively engage children and adolescents in food-related learning processes. These approaches move beyond traditional didactic teaching and include practical and participatory formats, such as cooking activities, school gardening, digital or app-based learning tools, workshops and educational camps, and game-based learning interventions. Objective: This narrative review aims to provide an overview of experiential school-based nutrition education interventions, describing the main types of programs implemented in school settings and summarizing their reported effects on nutrition knowledge, attitudes, and eating behaviors among children and adolescents. Results: Across intervention studies and systematic reviews, hands-on and interactive educational models, including cooking classes, gardening programs, digital learning tools, workshops or camps, and board game-based interventions, frequently report improvements in nutrition knowledge, attitudes toward food, food-related skills, and self-efficacy. These programs seek to strengthen food literacy by combining experiential learning with educational content delivered within the school environment. Evidence regarding changes in dietary intake, diet quality, and anthropometric outcomes is more heterogeneous, with some studies reporting improvements in eating behaviors and others showing more modest or short-term effects. Program outcomes appear to be influenced by several contextual factors, including intervention duration, curriculum integration, teacher involvement, and the availability of resources supporting implementation. Conclusions: Experiential and interactive approaches represent an increasingly adopted strategy in school-based nutrition education. Their effectiveness appears to depend on the quality of implementation, the degree of integration within the school curriculum, and the broader educational context. Future research should further explore how different experiential formats can be optimally integrated into school systems to support the development of food literacy and sustainable healthy eating behaviors among children and adolescents.

Objectives: Parental health literacy plays a pivotal role in shaping caregiving practices and influencing their children’s health. The aim of this systematic review is to analyze studies examining health literacy among parents raising children under five, in relation to caregiving practices and children’s health outcomes. Methods: The research was conducted in accordance with PRISMA protocol. The sample of the study was determined by using the terms related to “health literacy” AND “parent” (OR “caregiver” OR “mother” OR “father”) AND “child” AND “measure” (OR “instrument” OR “tool” OR “questionnaire” OR “survey” OR “interview”) in ERIC, PUBMED, Scopus and WOS databases published between 2015 and 2024. Results: Of the 1726 results identified, 18 studies met the inclusion criteria. The reviewed studies on parental health literacy place particular emphasis on oral health literacy, nutrition/food literacy, vaccine literacy, and fever literacy. Conclusions: Based on the included studies, parents’ health literacy is generally found to be significantly associated with the adequate fulfilment of children’s care needs, the implementation of appropriate parenting practices, and the effective management of childhood illnesses (although findings regarding vaccination willingness are inconsistent). Overall, these associations may carry long-term implications for children’s health. Full article

Background: Dining out has become increasingly prevalent in China, which is associated with higher intakes of energy, fat and sodium, elevating the risk of diet-related non-communicable diseases. However, evidence on color-coded nutrition labels for onsite prepared meals remains scarce. This study aimed to examine consumers’ perceptions of Dish-Choice, a three-color-coded onsite label, in comparison with the standard Nutrition Facts Label (NFL), to evaluate subjective perceptions of this novel label. Methods: A self-controlled trial was conducted among 3008 diners from canteens in Shanghai, with completing questionnaires twice: first on NFL perceptions, then three months later on Dish-Choice. Logistic regression and paired-sample comparison were used for analysis. Results: Compared with the NFL, Dish-Choice was associated with higher perceptual scores, with greater changes in overweight/obese, males, lower socio-economic status (SES) groups and those with poor dietary quality. Conclusions: The Dish-Choice label elicits more positive perceptual responses across multiple perceptual constructs. It is particularly well-received among vulnerable populations with lower health literacy, including men, lower-SES groups, and individuals with poor dietary habits. This supports its potential as a public health tool for on-site dining settings, though further research is needed to confirm its impact on actual food choices. Full article

Fertilizers play a crucial role in increasing grain yields and ensuring agricultural supply. However, heavy reliance on fertilizers has brought growing pressure on food security and environmental sustainability. Soil improvement technologies provide an effective way to reduce fertilizer use while maintaining agricultural productivity. This paper uses survey data from 808 farmers in China’s major grain-producing regions. It examines the effects of single and combined soil improvement technologies on fertilizer application intensity. Based on farmers’ capabilities, cognition, and production behaviors, this study further explores the moderating roles of digital literacy, psychological expectation, and continuous technology adoption. The results show that technology combinations have a stronger inhibitory effect on fertilizer reduction than a single technology. Digital literacy and continuous technology adoption strengthen this mitigation effect, while psychological expectations weaken it. The fertilizer-reduction effect is more evident in larger farms, non-transferred land, and farms with higher levels of mechanization. Future agricultural policies should place more emphasis on the popularization of technology combinations, such as through targeted subsidies and special supporting funds. At the same time, differentiated support measures should be formulated in light of local conditions to curb excessive fertilizer application and promote the sustainable development of agriculture.

Background: During the early years of the coronavirus disease 2019 (COVID-19) pandemic, many schools found their staff, specifically teachers, adapting their roles to address social and health challenges, such as food insecurity and health literacy. Given the challenges these school-based communities faced, and continue to face, a clear gap was exposed during these early years of the public health crisis: a lack of community-centered professionals who can assist with social health factors impacting health and well-being. Methods: In this descriptive report, we examine the process and implementation of training two teachers to become community-centered professionals, specifically community health workers (CHWs), to serve schools located in socioeconomically challenged neighborhoods of urban regions. We explore their training and how these CHW–teachers prescribed social health interventions across four major domains: (a) access to medical and environmental equipment, (b) mental health challenges, (c) food insecurity, and (d) health literacy. We describe the specific interventions they implemented and the potential economic value and practicality of the overall initiative. Outputs: In less than one year, two teachers were successfully trained as CHWs in and for underserved communities. These CHW–teachers conducted informal surveys based on objectives of health themes that aligned with absenteeism. Both the process and implementation of the CHW training and CHW-led school-based interventions proved cost-effective and practical. Conclusions: Having CHW–teachers in schools is practical, may offer economic value, and is likely to complement additional health initiatives at schools (e.g., school nurses). As a small-scale pilot initiative, further studies should evaluate CHW–teacher impact on school-based goals, such as attendance rates, while this report focuses on early implementation processes.

Background/Objectives: There is a limited body of research on evidence-based food literacy education for adolescents. The inquiry-based curriculum, Teens CAN: Comprehensive Food Literacy in Cooking, Agriculture, and Nutrition, was designed to improve food literacy among adolescents ages 14–18 years. This study aimed to assess the Teens CAN curriculum by examining changes in food literacy outcomes among high school–aged adolescents and explore the effectiveness of undergraduate facilitators in implementing the curriculum with fidelity. Methods: This quasi-experimental pilot study was conducted among high school students comprising intervention (n =14) and comparison groups (n = 16). All Teens CAN lessons were delivered by trained undergraduate facilitators, and lesson fidelity was measured by a trained observer. Baseline and follow-up survey measures assessed various components of food literacy, including adolescent nutrition knowledge, diet quality, and intrinsic motivation to prepare healthy food (cooking self-efficacy). Between-group differences were examined using t-tests, and ANCOVA regression models assessed associations between changes in baseline to follow-up nutrition knowledge, diet quality, and cooking self-efficacy, adjusting for baseline values. Results: The adolescents in the intervention group had a significant increase in nutrition knowledge scores compared to the comparison group (4.6 ± 2.3 vs. 1.1 ± 3.7, respectively; p = 0.01). High fidelity (≥80%) was achieved across lessons and lesson components. In ANCOVA regression analyses, participation in the intervention was positively associated with nutrition knowledge (β = 3.3, 95% CI [0.87–5.80]; p = 0.01), providing evidence for future investigation. Conclusions: The findings from this pilot study suggest that Teens CAN has the potential to positively influence food literacy and related behaviors among adolescents, therefore warranting further investigation in a larger population.

Background/Objectives: Diet is implicated in the high burden of mental health on society, and research examining associations between these two fields is growing. However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Methods: Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Results: Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Conclusions: Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States.

Diet quality, nutrition knowledge, and psychosomatic literacy—defined as the understanding of the interactions between diet, gut microbiota, and mental well-being—may shape weight-related behaviours in youth. This study used a cross-sectional design to integrate these domains with digital information pathways in Central–Eastern Europe. This study assessed diet quality, nutrition, and psychosomatic knowledge, supplement use, and health-information sources among Polish adolescents and young adults, with emphasis on age-related differences and the role of social media. A cross-sectional, anonymous online survey (October 2025–January 2026) was conducted in Poland (final analytical sample: n = 478; adolescents 15–19 years vs. young adults 20–30 years). Of 591 individuals who accessed the survey, 478 were included in the final analytical sample. Diet quality was estimated from FFQ data using KomPAN-derived indices (pHDI-10, nHDI-14, DQI). Nutrition knowledge (0–25 points), psychosomatic/gut–brain indicators, supplementation, and information sources were analysed using χ²/Fisher tests and Mann–Whitney U tests with effect sizes. The primary outcomes measured were dietary supplement use and excess body weight (BMI ≥ 25 kg/m²). Multivariable logistic regression examined predictors of supplement use and BMI ≥ 25 kg/m². Overall diet quality was low to moderate, with limited intake of whole grains, legumes, and fish, and common nutrition misconceptions. Social media was the most frequently indicated source of diet/supplement information and was independently associated with more frequent supplement use (OR = 2.29; 95% CI: 1.43–3.64). Adolescents reported lower whole-grain intake and more misconceptions than young adults. Predictors of BMI ≥ 25 kg/m² included male sex (OR = 2.46; 95% CI: 1.46–4.15), lower education, and lower nutrition knowledge, while age showed a non-linear positive association with excess body weight. Polish adolescents and young adults show gaps between declared pro-health attitudes and actual diet quality/competencies. Social media reliance appears particularly linked to product-oriented behaviours (supplementation). Prevention should strengthen nutrition and food safety education, digital health literacy, and professional guidance on supplementation, especially in adolescents. Our findings suggest that social media is a primary driver for dietary supplementation among Polish youth, more so than objective nutrition knowledge. While diet quality is linked to weight status, the relationship is complex. These results may inform future public health interventions targeting digital health literacy to promote balanced nutrition and safe supplementation practices. Full article

South African irrigation schemes face critical challenges of water scarcity, infrastructure deterioration, and limited monitoring capacity, threatening agricultural productivity and food security. This scoping review systematically analyses 59 peer-reviewed publications (2000–2025) on sensor-based and acoustic irrigation monitoring technologies in South Africa, using transformer-based natural language processing (Sentence-BERT embeddings), unsupervised Machine Learning (UMAP dimensionality reduction, HDBSCAN clustering), and geospatial mapping applied to literature retrieved from Web of Science and Scopus. Results show that water quality monitoring (42.4% of studies) and remote sensing (25.4%) dominate the national research landscape, while soil moisture sensing and modelling remain comparatively limited. Notably, no peer-reviewed studies applying acoustic monitoring technologies to irrigation were identified, representing a critical gap despite proven international applications for leak detection (95–98% accuracy), widespread infrastructure aging (over 50% of schemes exceeding 30 years), and reported water losses of 30–60% in poorly managed systems. Reported experimental water savings range from 15% to 30%, yet applications remain largely confined to pilot-scale implementations concentrated within a limited number of Water Management Areas. Persistent adoption barriers include infrastructure unreliability, financial inaccessibility, limited digital literacy, and weak institutional coordination. The review recommends: (i) expanding research coverage across underrepresented regions and Water Management Areas; (ii) strengthening extension support and technical training to enable broader adoption; and (iii) integrating low-cost sensor networks with predictive, data-driven irrigation advisory systems. These priorities aim to support scalable, context-sensitive irrigation modernisation under increasing water scarcity pressures. Full article

Background: In Greece, nutrition education is not taught as an independent subject but is incorporated across multiple disciplines. Objective: To evaluate the extent, distribution, and thematic orientation of nutrition-related content in Greek secondary school textbooks. Methods: A systematic content analysis was conducted on all officially approved textbooks used in Greek secondary education during the academic year 2022–2023. A total of 164 textbooks (26,914 pages) were analyzed. Nutrition-related references were systematically identified using predefined keywords and categorized into thematic domains. Coding was performed independently by two researchers (Cohen’s κ = 0.84). Results: A total of 1426 nutrition-related references were identified. Nutrition-related content was unevenly distributed, with 57.1% in Gymnasium textbooks and 42.9% in Lyceum textbooks. When normalized, Gymnasium textbooks contained 7.47 references per 100 pages compared with 3.82 in Lyceum. Content was primarily focused on biological concepts (27.1%) and health/disease prevention (20.3%), while behavioral (16.5%), psychosocial (16.2%), and sustainability-related (19.8%) dimensions were less represented. No references addressed skills-based nutrition education. Conclusions: Nutrition education in Greek textbooks is present but fragmented and predominantly biologically oriented. The lack of behavioral and skills-based content suggests the need for more comprehensive and interdisciplinary educational approaches. Full article

Background/Objectives: Cardiovascular disease (CVD) is the leading cause of death in China. While obesity and dietary patterns are well-established factors, the independent association between overall dietary quality and CVD prevalence—specifically whether this link persists regardless of Body Mass Index (BMI)—requires further clarification. Furthermore, the behavioral and cognitive correlates that drive dietary quality, such as health literacy, remain insufficiently explored. This study evaluated the association of dietary quality with self-reported CVD among Chinese adults, independent of BMI, and identified the key behavioral and cognitive factors associated with dietary adherence in this population. Methods: This cross-sectional study surveyed 975 Chinese adults through anonymous questionnaires and collected self-reported data on CVD, BMI, dietary quality, and health literacy. One-way analysis of variance (ANOVA) and the chi-square test were used to compare the characteristics between groups, and multivariate Logistic regression was used to analyze the association between dietary quality and the odds of CVD, sequentially adjusting for variables such as BMI, physical activity. Results: Higher dietary quality was independently associated with lower odds of CVD (Model 3: OR = 0.879, 95% CI: 0.845–0.915, p < 0.001). Notably, this inverse association remained significant after adjusting for BMI, which itself showed no significant association with CVD prevalence in the multivariable model. Regarding population profiling, poor dietary quality was significantly related to regular smoking (p < 0.05), whereas age, gender, residence, employment status, and BMI showed no significant associations with dietary quality categories. Furthermore, health literacy (p < 0.05) and physical activity (p < 0.05) showed positive associations with superior dietary quality. Conclusions: Dietary quality is a significant independent factor inversely associated with CVD prevalence, regardless of obesity status. Suboptimal dietary habits cluster among smokers and individuals with lower health literacy and physical activity levels, showing a stronger association with cognitive and behavioral factors than with demographic or occupational characteristics. Interventions should prioritize enhancing health literacy and addressing the clustering of unhealthy behaviors to effectively address the cardiovascular burden in the Chinese population.

While Artificial Intelligence (AI) approaches date back more than 60 years, there is no doubt that in the last 4 years, we have entered the era of AI. The advanced capabilities of Generative AI (GenAI) and Large Language Models (LLMs) have noticeably reshaped multiple sectors, becoming a driving force in participatory environments. Recent developments in Machine/Deep Learning (ML/DL) and Natural Language Processing (NLP) have enabled the introduction of tools and applications integrated into various professional fields. Areas ranging from education and media to art, tourism, and food science incorporate AI technologies to optimize established workflows, facilitate change, enhance creativity, and foster interaction. The current Special Issue includes nineteen multidisciplinary research works exploring AI in participatory environments, primarily focusing on technologies, ethics, and literacy aspects. Employing diverse methodologies, the research identifies various uses of AI along with the critical ethical and legal risks and challenges they entail. Concerns about inaccuracy, algorithmic bias, data infringements, and the potential erosion of transparency and interpretability need to be addressed in every phase of the design and implementation of AI technologies. Co-creative human-in-the-loop processes and human judgment need to be further strengthened and supported through digital/AI literacy initiatives. In this regard, effective regulatory frameworks, inclusive institutional strategies, and targeted training programs can ensure responsible and trustworthy AI use with a balance between technological evolution and human oversight.

Background/Objectives: Nutrition literacy (NL) is an important determinant of healthy dietary behaviors, particularly among population groups at increased cardiovascular risk. This study aimed to describe NL and adherence to the Mediterranean diet (MD), and to describe their association, among women aged 45–70 years living in socioeconomically disadvantaged neighborhoods in Florence (Italy). Methods: A cross-sectional study was conducted within the Joint Action on Cardiovascular Diseases and Diabetes (JACARDI). This study represents the second step of Phase 1 of the Optimising Health Literacy and Access (Ophelia) process. Women were recruited in a primary health care setting using a convenience sample. NL was assessed using the Italian-adapted version of the Nutrition Literacy Assessment Instrument (NLit-IT) and the adherence to the MD using MEDI-LITE. Results: Questionnaires filled in by 143 women were included in the analysis. Most participants (63.6%) had “possibility of poor NL”. Regarding the MD, 60.8% showed moderate and 9.1% low adherence. A positive correlation was observed between total NLit-IT and MEDI-LITE scores (rho = 0.214; p = 0.011). In logistic regression analysis, an increase in the NLit-IT total score was associated with a higher possibility of having a moderate/high adherence to the MD (OR 1.157). Only the subscale “Food Label and Numeracy” of NLit-IT emerged as an independent predictor of moderate/high adherence to the MD (OR 1.416). Conclusions: These preliminary findings suggest a possible association between NL and adherence to the MD. Further longitudinal and interventional studies are needed to confirm these results and inform tailored nutrition education interventions. Full article

Background: Given the limited evidence in the field, the present study aimed to explore the association of UPF intake with food literacy levels in an adult Mediterranean-based population. Methods: Self-reported demographic and anthropometric data were collected from 317 apparently healthy adults (52.5% males) Food literacy and dietary intake of this population were also assessed. Foods were classified as ultra-processed according to the NOVA system, and their contribution to total daily energy intake (%) was calculated. Then, participants were grouped into the (1) higher UPF intake (HUPFI), and (2) lower UPF intake (LUPFI) groups, based on the median value of this population as a cut-off. Results: Between-group analysis revealed that LUPFI scored statistically significantly higher than the HUPFI group in total food literacy (93.5 [84.0–104.0] vs. 86.0 [78.0–99.0], p < 0.001) and in three out of five food literacy sub-dimensions. Sub-analysis revealed no differences between LUPFI and HUPFI groups of individuals with normal weight. In participants with overweight or obesity, the LUPFI group scored lower than the HUPFI in the total food literacy score (95.0 [87.0–104.0] vs. 81.0 [70.0–94.0], p < 0.001) and in each sub-dimension. Conclusions: Higher UPF intake was associated, in adults with overweight or obesity, with lower levels of food literacy. Full article

Higher rates of food insecurity have been observed among Hispanic immigrants, yet these individuals have traditionally been excluded from food insecurity survey development. The most common Spanish translated food insecurity scale—the Spanish Translation of the U.S. Household Food Security Survey Module (S-FSSM)—may not be capturing how Spanish-speaking immigrant parents conceptualize food insecurity. The purpose of this study was to gain insight into how Spanish-speaking immigrant parents with low English literacy conceptualize household food insecurity within the 18-item S-FSSM and to use this information to revise the S-FSSM instrument. Researchers conducted two rounds of cognitive interviews with Spanish-speaking adults at a community center in Houston, TX, USA (N = 19; Round 1: n = 9, October 2023; Round 2: n = 10, July 2024). Researchers used participants’ feedback to refine the S-FSSM. All participants were female (Rounds 1 and 2 = 100%) and most born in Mexico (Round 1 = 66.7%; Round 2 = 50%). In Round 1, eight items were combined to enhance cultural relevance and to add definitions. Follow-up questions were added to improve clarity. Two items were revised for relevancy, two items had no change, six items were deleted. In Round 2, modifications to wording occurred and one item was added. The revised scale, named Food Access Measure for Immigrant Latinos In America (FAMILIA), resulted in 17 survey items. Study findings suggested that the S-FSSM needed refinement to enhance relevancy for Spanish-speaking immigrant parents with low English literacy. Full article
