Background/Objectives: Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder with implications for individual quality of life and society. Patients with IBS suffer a variety of symptoms but have few treatment options. The level of satisfaction with IBS treatment is low, stressing the need to expand the IBS treatment toolbox. The aim of this study is to describe drivers and barriers to the implementation of time-restricted eating (TRE) as a treatment alternative for patients with IBS. Methods: A convenience sample of 14 informants was drawn from a pool of 97 successful participants in an eight-week 16:8 TRE intervention. The informants partook in audio-recorded semi-structured in-depth interviews. Recordings were processed by a computer language model and interview transcripts were generated automatically. The transcripts were proofread, structured and analysed with a reflexive inductive thematic analysis approach. Results: The analysis generated six main themes consisting of 18 sub-themes in total. One main theme describes drivers of implementation concerning domains such as motivation, supporting factors, mentality, behaviour and determinants of sustainability. The results from this study are largely coherent with the findings from earlier feasibility studies conducted on other populations, but several key differences related to population characteristics emerged. Conclusions: Overall, the analysis suggests that TRE can be a feasible treatment option for IBS, but successful implementation is dependent on individual ability, external support and symptom relief.

Drawing on the Seeking Proxies for Internal States (SPIS) model and the concept of Difficulties in Accessing Internal States (DAIS), the present study examined the statistical associations among self-esteem, DAIS, body-checking, and disordered eating patterns (DEP). Within the SPIS framework, self-esteem is conceptualized as an evaluative internal state that may be appraised through externally observable proxies, such as body appearance. Cross-sectional data were collected from 200 adults recruited through Prolific Academic. Hayes’ PROCESS macro was used to test simple and serial mediation models examining whether DAIS and body-checking statistically account for associations between state self-esteem and DEP. Lower self-esteem was associated with higher DEP. Both DAIS and body-checking statistically accounted for portions of this association in simple mediation models. In a serial mediation model, the fully sequential pathway (self-esteem → DAIS → body-checking → DEP) remained statistically significant after accounting for shared variance among mediators. Given the cross-sectional design, these findings cannot establish temporal or causal relationships, but the observed pattern of associations is compatible with the proposed conceptual process. Additionally, our findings are based on a nonclinical sample and reflect variability in subclinical eating pathology. Implications for extending the SPIS framework to dimensional eating-related phenomena are discussed. Full article

Background/Objectives: Patients with food allergy (FA) may exhibit dysfunctional eating behaviours and/or food aversions that extend beyond the necessary allergen elimination diet and may result in avoidant/restrictive food intake disorder (ARFID) or food neophobia (FN); however, no data are available on adults. This study aimed to explore ARFID, FN, FA anxiety, and eating styles in adults with FA, analysing influences of sociodemographic and clinical factors. Methods: This cross-sectional preliminary study involved 79 adults with FA, who completed the Nine Item ARFID screen (NIAS), Food Neophobia Scale (FNS), Scale of Food Allergy Anxiety (SOFAA), and Dutch Eating Behaviour Questionnaire (DEBQ—brief). Pearson and Spearman correlation coefficients and multiple linear regressions were performed (p < 0.05). Results: In total, 25% and 73% of participants scored positively for ARFID and FN, respectively. A positive correlation was observed between FN and ARFID levels (p < 0.006), and between FN and FA anxiety (p < 0.001). Current psychological problems positively correlated with ARFID (p = 0.004), FN (p = 0.006), and FA anxiety scores (p = 0.03). Restrained eating was positively associated with female gender (p < 0.001), and ARFID (p = 0.002) and FN scores (p = 0.028). External eating was negatively correlated with ARFID (p = 0.004). Adrenaline auto-injector (AAI) prescription was negatively associated with ARFID (p < 001) and restrained eating (p = 0.006), while previous anaphylaxis was negatively associated with ARFID (p = 0.020) and positively associated with external eating (p = 0.021). Multiple logistic regression models confirmed that restrained eating was associated with a higher probability of both ARFID (p = 0.031) and FN (p = 0.074). Conclusions: Clinicians should be aware of the risk of ARFID and FN among adult patients with FA and recommend appropriate psychological and dietary support. Further studies are needed to better understand the protective and precipitating factors of ARFID and FN to develop effective prevention and treatment strategies. Full article

Background/Objectives: Functional foods are widely discussed in nutrition research, yet their consumption is rarely quantified using a standardized, food-based metric. We developed the Functional Food Consumption Index (FunFoCI) and conducted an initial evaluation of its performance in adults. Methods: In this cross-sectional study, 500 adults (≥18 years, 286 women, 214 men) were assessed using a 210-item quantitative food frequency questionnaire (FFQ) and a 3 day food record (FR). Candidate index foods were evaluated by five experts, using a 4-point Likert scale to establish content validity, and the finalized FunFoCI comprised 100 foods across nine groups: fruits; vegetables; whole grains; legumes; nuts and oilseeds; fermented foods and products; animal-based foods; functional oils; and spices, herbal teas, and functional beverages. FunFoCI scoring used a sample distribution-based percentile approach, including modifications for zero-inflated or sparsely consumed items, followed by group-level normalization (0–1), equal weighting across nine groups, and rescaling to 0–100. FR data were used to examine the between-method feasibility of the scoring approach. The convergent validity was assessed via correlation analyses, with the Diet Quality Index-International (DQI-I) and Healthy Eating Index-2015 (HEI-2015) derived from both FFQ and FR data, and additional correlation analyses and robustness checks were conducted to examine associations among key study variables. Known group patterns were examined across sociodemographic, lifestyle, and anthropometric characteristics. Results: Content evaluation supported index coverage (S-CVI/Ave = 0.912; S-CVI/UA = 0.877; mean modified kappa = 0.899). The mean FunFoCI total scores were 32.68 ± 11.92 (FFQ) and 13.29 ± 4.65 (FR). Participants were classified into low (32.8%, n = 164), moderate (33.0%, n = 165), and high (34.2%, n = 171) FunFoCI categories. FunFoCI correlated with FFQ-derived DQI-I and HEI-2015 (r = 0.367 and r = 0.368; both p < 0.001), and both indices increased across ascending FunFoCI total scores (p < 0.001). The FFQ-derived FunFoCI total score was correlated with the FR-derived FunFoCI score (r = 0.294; p < 0.001). FunFoCI scores showed differences across participant sociodemographic, lifestyle and anthropometric characteristics. Conclusions: FunFoCI is a newly developed, expert-reviewed, food-based index with transparent, sample distribution-based scoring and normalized aggregation. Its initial evaluation supports its use for the standardized quantification of relative functional food consumption in adults, while further studies should assess the reliability and external validation criteria in other populations and study designs.

With global economic development and rising living standards, expectations regarding the quality of staple rice have become increasingly multifaceted. This shift has imposed more stringent demands on high-quality rice breeding and field management and has stimulated research into the mechanisms underlying changes in rice quality. This article explores how assessments of rice quality have evolved from a primary emphasis on appearance, eating and processing quality to include stronger requirements for nutritional value and safety. In rice production systems, quality outcomes are influenced by interactions among genetic traits, ecological factors and field management practices. Through genetic improvement, biological breeding techniques and precise field management, improvements in appearance, eating and nutritional qualities can be achieved. Although climate change is an uncontrollable external factor affecting rice quality, constructing multi-factor dynamic simulation models that target key genes has been proposed as a strategy to enhance stress resistance and guide rice breeding. Rice safety and quality depend on the rational use of pesticides in terms of timing and dosage, which can help mitigate disease and insect resistance while reducing the risks associated with pesticide residues and toxins. Furthermore, the application of artificial intelligence technologies in biological breeding and field management can shorten breeding cycles, improve disease and pest outbreak prediction and support the timely formulation of treatment prescriptions.

Background and Aim: Obesity has reached alarming levels globally and across the Middle East. In Saudi Arabia, approximately one-third of Saudi adults have obesity, representing a major public health concern. Understanding behavioral factors underlying obesity is essential; therefore, this study aimed to investigate the association between eating styles and obesity indicators among Saudi adults and to examine gender differences in these associations. Methods: This cross-sectional study included 997 adult (405 males and 592 females) aged ≥ 18 years residing in Saudi Arabia. Data were collected using a self-administered questionnaire covering sociodemographic characteristics, anthropometric measures, health status. Eating behaviors were assessed using the validated Dutch Eating Behavior Questionnaire (DEBQ), which measures restrained, emotional, and external eating styles. Regression models were used to examine gender differences in mean eating style scores and to assess associations between eating styles, categorical BMI, and body fatness. Results: The mean age of participants was 37.05 ± 13.39 years. Significant gender differences were observed in BMI, body fatness, and physical activity levels. Females demonstrated higher restrained eating scores compared with males (β = −0.14; 95% CI: −0.24, −0.04; p = 0.008). Participants with obesity exhibited higher emotional eating scores, while external eating was more prevalent among underweight participants. Body fatness was significantly associated with emotional and external eating but not restrained eating. Conclusions: BMI status appears to be associated with specific eating styles, particularly unhealthy eating behaviors. These findings highlight the importance of behavioral-focused nutritional interventions that support eating regulation rather than emphasizing weight loss alone. Full article

Background: Metabolic syndrome (MetS) is influenced by behavioral and genetic factors, yet evidence on eating behavior patterns and related genetic polymorphisms in Central Asian populations remains limited. Aim: The aim of this study was to assess eating behaviors among adults with and without MetS and evaluate their associations with clinical indicators and ADIPOQ rs266729 and MC4R rs17782313 variants. Methods: A cross-sectional study of 200 adults (115 non-MetS, 85 MetS) was conducted using Dutch Eating Behavior Questionnaire (DEBQ), standardized clinical measurements, and PCR-RFLP genotyping. Results: Participants with MetS were older than non-MetS adults (52 vs. 47 years; p = 0.004) and had substantially higher systolic blood pressure (126 vs. 114 mmHg; p < 0.001), diastolic blood pressure (83 vs. 74 mmHg; p < 0.001), and BMI (32.2 vs. 25.9 kg/m²; p < 0.001). Waist circumference, hip circumference, triglycerides, total cholesterol, and LDL were also significantly higher, while HDL was lower (1.13 ± 0.40 vs. 1.58 ± 1.50 mmol/L; p = 0.008). DEBQ restrained, emotional, and external eating scores showed no differences between groups (all p > 0.05). Eating behavior distribution was similar (p = 0.291). ADIPOQ genotypes (CC/CG/GG) did not differ by MetS status (p = 0.227), nor did MC4R variants (p = 0.679). Among MetS participants, clinical indicators did not vary across eating behavior categories, and no associations were observed between eating behavior and either polymorphism. Conclusions: Despite clear clinical and metabolic differences between MetS and non-MetS groups, neither eating behavior patterns nor ADIPOQ and MC4R variants were associated with metabolic measures among MetS group.

The circadian cycle regulates metabolism in response to external stimuli, such as light exposure, sleep schedules, and eating patterns. However, misalignment between internal biological rhythms and social demands can compromise food choices, potentially leading to overweight and obesity. This research aimed to assess how a person’s chronotype links to social jet lag (SJL), which in turn would relate to their nutritional status and food consumption patterns as a university student. 617 students from a State University located in the State of Paraná, Brazil, completed a cross-sectional research study that collected sociodemographic information/anthropometrics by means of an online survey. It included self-reported height/weight data and dietary habits. The Munich Chronotype Questionnaire (MCTQ) was utilized to determine each participant’s chronotype classification and SJL calculation. Researchers found that nearly half of the students (49.3%) displayed an Intermediate Chronotype, which is associated with a diet that contained elements of the “Mixed” Diet, meaning there are equal portions of healthy food (Fresh Fruits, Beans, etc.) and unhealthy foods (Sweetened Beverages). The multivariate logistic regression analyses identified age as a significant predictor of obesity risk (OR: 1.15, p < 0.001), while dietary habits such as fruit consumption played a protective role. Additionally, having a breakfast protected them from being classified as obese compared to those who did not eat breakfast (OR = 0.59). Contrary to expectations, late-night supper was not a statistically significant predictor in the adjusted model. Predictors of an Intermediate chronotype included being male and eating morning snacks regularly. The results of this study suggest that students with an intermediate chronotype will predictably have skewed eating patterns, such as skipping breakfast and eating late—both of which affect obesity risks. Nutritional strategies for university students should focus on promoting circadian regularity and optimizing meal timing. Full article

Background: Coeliac disease (CD) is an autoimmune chronic condition that requires a strict diet without gluten as a single effective treatment. However, adherence to a life-long gluten-free diet (GFD) may promote psychological suffering and disordered eating. The Coeliac Disease Food Attitudes and Behaviours Scale (CD-FAB) is the only instrument specifically designed to evaluate these aspects in individuals with CD. Objective: This study aimed to translate the CD-FAB and test its reliability in the Brazilian population. Methods: The research was conducted in three stages: (i) translation and cultural adaptation of CD-FAB into Brazilian Portuguese; (ii) pretesting with Brazilian individuals diagnosed with CD to assess item understanding; and (iii) psychometric evaluation through reproducibility (test–retest reliability) via intraclass correlation coefficient (ICC) and internal consistency via Cronbach’s alpha. Results: The CD-FAB was successfully adapted to the Brazilian CD population (Child CD-FAB-BR) and demonstrated strong internal consistency (α = 0.807) and an intraclass correlation coefficient (ICC = 0.928). Conclusions: The Brazilian version of CD-FAB proved to be reliable for assessing food attitudes and behaviours in people with CD, potentially allowing for the identification of factors to guide research and clinical practice by driving behaviour-based strategies to improve nutritional education and strategic policies for coeliac patients. Studies with larger and more diverse samples are recommended to provide external validation of the instrument. Full article

Background/Objectives: The increasing prevalence of obesity among children and adolescents is alarming, and the obesogenic environment is considered a major contributing factor to this public health concern. Nevertheless, individuals exposed to the same obesogenic environment exhibit considerable variability in their body weight and eating behaviors. Therefore, this study investigated the relationships between eating behaviors, sensory processing profiles, and peripheral biomarkers in the context of adolescent obesity. Methods: A total of 99 adolescents aged 11–18 years (51 in the obese group and 48 in the control group) were enrolled in the study. Blood and saliva samples were obtained from participants. All participants also completed a Sociodemographic Information Form, the Adolescent/Adult Sensory Profile (A/ASP), and the Dutch Eating Behavior Questionnaire (DEBQ). Results: No statistically significant differences were found between the groups in any of the sensory processing quadrants (p > 0.05). A moderate positive correlation was observed between Sensory Sensitivity (A/ASP) and Emotional Eating (DEBQ) (r = 0.442, p < 0.001), whereas no other associations between A/ASP quadrants and DEBQ subscales reached statistical significance after adjustment for multiple comparisons. After controlling for the effects of sex, BMI and physical activity, plasma leptin, ghrelin, and salivary cortisol levels were not significantly associated with restrained, emotional, or external eating behaviors (p > 0.05). Conclusions: Obese and control group adolescents exhibited similar sensory processing profiles, yet higher sensory sensitivity scores were associated with greater emotional eating. These findings suggest that sensory sensitivity may be relevant for understanding emotional eating in adolescence; however, longitudinal research is required to determine whether this association is causal and to clarify the processes underlying it.

Background: Mukbang, an online trend featuring individuals eating large amounts of food while interacting with viewers, has become increasingly popular worldwide, including in Saudi Arabia. This study explored how often Saudi adults watch mukbang videos and whether viewing frequency is related to emotional, external, and restrained eating behaviors. Methods: An online survey was completed by 160 participants, of whom 70 had watched mukbang videos in the past 30 days and were included in the analysis. Results: Viewing frequency was not significantly associated with any eating behavior type. Education level showed a significant relationship with viewing habits, with participants who had higher educational attainment reporting less frequent viewing; however, this association should be interpreted cautiously, as media awareness was not directly measured. Conclusions: Overall, the findings provide preliminary insight into how individual characteristics may shape engagement with mukbang content and highlight the need for further research that examines additional psychological and cultural factors.

Positive Body Image (PBI) has been conceptualized as a multidimensional construct encompassing acceptance, functionality appreciation, and self-care, yet little is known about the lived processes through which women move from self-criticism to reconciliation with their bodies. This study aimed to explore how women experience, construct, and sustain PBI in their everyday lives, and to identify the psychological and contextual factors that facilitate its development. Semi-structured interviews were conducted with ten women in Greece (ages 18–62) of diverse body sizes, educational backgrounds, and life circumstances, which were then analyzed using interpretative phenomenological analysis. Participants were recruited through convenience sampling and interviewed online between July and August 2025. Findings revealed three superordinate themes—(1) Catalysts of Realism and Self-Care, (2) From Rejection to Reconciliation, and (3) My Own Positive Body Image—comprising nine subthemes that together illustrated a developmental process of body acceptance and meaning-making. Findings revealed a trajectory from self-rejection to reconciliation, marked by shifts from external appearance to holistic embodiment, and from self-criticism to compassion, functionality appreciation, and intrinsic motivation. Participants described mindful self-care practices—particularly exercise and healthy eating—as acts of self-nurturing, supported by psychotherapy, positive social relationships, and turning points such as illness, aging, or personal maturation. These catalysts facilitated a reorientation of body image away from societal ideals and toward health, resilience, and existential meaning. The study contributes to understanding how women develop sustainable forms of PBI, highlighting the importance of self-compassion, supportive contexts, and body functionality. These insights have implications for interventions aiming to promote wellbeing, resilience, and healthier relationships with the body across the lifespan. Full article

Background/Objectives: Sustainable nutrition is essential for human and planetary health. The Transtheoretical Model-based Sustainable Nutrition Behavior Scale (TTM-SNBS) was developed to assess sustainable nutrition behaviors and the dynamic processes of behavior change in adolescents. Methods: The item pool was generated through literature review and expert consultation using the Delphi technique (10 experts, three rounds). Construct validity was assessed using exploratory and confirmatory factor analyses. Reliability was evaluated through Cronbach’s alpha and test–retest methods. External validity was examined through correlations with the Sustainable and Healthy Eating Behaviors Scale (SHEBS), following COSMIN standards. The study included 512 adolescents aged 14–18 years (54% female) from public high schools in Ankara, Türkiye. Results: Initially, 75 items were developed through expert evaluation. After preliminary testing, two items with low and negative correlations were removed; 73 were retained for validation. Factor analyses and refinement produced a 45-item final validated scale comprising one stage of change item and five subscales: cognitive processes (14 items), behavioral processes (18 items), decisional balance—pros (4 items), decisional balance—cons (4 items), and self-efficacy (4 items). Items showed good discrimination (>0.27). Cronbach’s alpha values ranged from 0.67 to 0.93, and fit indices were acceptable (χ²/df = 2.8–4.2; RMSEA = 0.045–0.065). External validity was supported by significant positive correlations with the SHEBS. Conclusions: The TTM-SNBS is the first psychometrically validated, theory-based instrument to assess sustainable nutrition behaviors in adolescents. It offers a reliable and valid instrument to support future research and interventions promoting sustainable dietary practices. Full article

Background: Recognizing and balancing internal and external appetite cues is critical for controlling food intake in young children. The main aim of this pilot study was to validate a Hebrew-language Picture-Based Appetite Assessment (PBAA) for 6–9-years-old children. Specifically, the scale’s ability to reflect changes in perceptions of hunger and satiety based on a story and on their actual eating experiences. Methodology: In Part 1 (n = 99), a PBAA was used to rate a character’s hunger level according to a story. In Part 2 (n = 46), the child’s hunger level before and after lunch was assessed, and in Part 3 (n = 55), the child’s hunger level before and after unrestricted snack consumption was assessed. Results: After hearing a story, participants could identify whether a character in a story was hungry (95%) or full (85%) (Part 1). Their reported appetite levels decreased after consuming lunch (p-value < 0.001) (Part 2). When participants were given unrestricted access to snacks, they preferred highly processed sweets with no difference in hunger level before (Part 3). There were no differences between girls and boys except for the reported satiety after lunch, which was greater in older girls compared to younger girls, yet similar between older and younger boys. Conclusions: Participants successfully interpreted the PBAA scale based on the story character and reported lower hunger after eating lunch. Among girls, older age was associated with a greater difference in hunger levels before and after lunch. Most participants reported satiety after consuming unrestricted snacks, which was not related to their hunger level before. Full article

Background: Emotion regulation (ER) difficulties are closely linked to maladaptive coping strategies, including impulsive and emotional eating, which undermine health and well-being in young adults. Technical university students are particularly vulnerable due to factors such as a high academic workload, sedentary behavior, and performance-related stress. This study evaluated the effects of a four-week structured physical activity intervention on ER and eating behaviors among engineering students. Methods: Seventy first- and second-year computer science and engineering students (40 males and 30 females, aged 19–25 years) from Politehnica University of Bucharest participated in the study. The intervention included three weekly supervised training sessions and a daily step count requirement (≥6000 steps), verified via weekly smartphone submissions. Pre- and post-intervention assessments employed the Difficulties in Emotion Regulation Scale (DERS-36) and the Adult Eating Behavior Questionnaire (AEBQ-35). Data were analyzed using Kolmogorov–Smirnov tests, Wilcoxon signed-rank tests, and paired-sample t-tests. Results: Significant improvements were observed in five ER domains—non-acceptance of emotional responses, goal-directed behavior, impulse control, access to regulation strategies, and emotional clarity (all p < 0.01). No change occurred in emotional awareness (p > 0.05). Eating behaviors (restrained, emotional, and external eating) showed no significant differences pre- and post-intervention (all p > 0.05). Conclusions: A short-term, structured physical activity program enhanced emotion regulation capacities but did not alter eating behaviors in the short run. These findings highlight the feasibility of embedding low-cost, exercise-based modules into higher education to strengthen students’ psychological resilience. Longer and multimodal interventions may be required to produce measurable changes in eating behaviors. Full article
