Dyslipidemia in adolescents represents an early and potentially modifiable stage in the lifelong trajectory of cardiovascular disease. However, optimal lipid screening strategies in this age group remain controversial, particularly regarding feasibility, biological relevance, and reliance on family history. Non-high-density lipoprotein cholesterol (non-HDL cholesterol) has emerged as a promising screening marker because it reflects the total burden of atherogenic lipoproteins and can be reliably assessed even without fasting, making it particularly suitable for large-scale pediatric screening settings. A recent nationwide population-based study of Korean adolescents provides robust real-world evidence supporting the utility of non-HDL cholesterol in dyslipidemia screening, across both sexes and independent of familial lipid risk. From a nutritional and public health perspective, non-HDL cholesterol is closely related to dietary habits, postprandial hyperlipidemia, and metabolic stress, and is particularly important in the modern food environment characterized by increased consumption of ultra-processed foods. This Opinion discusses the biological rationale, clinical feasibility, and population-level implications of non-HDL cholesterol-based screening in adolescents. By linking lipid biology with nutrition-focused prevention and lifelong cardiovascular health, non-HDL cholesterol may serve as a practical gatekeeper for early risk identification and upstream intervention.

Background: This study aimed to analyze the relationship between dietary habits and mental health among people with disability (PWD) using the Panel Survey of Employment for the Disabled (PSED). Significant differences according to gender and age were identified. Methods: This study used secondary data (the second wave of the PSED) collected from 2016 to 2018 (n = 4345). Dietary habits (i.e., skipping meals and regular meal timing) were analyzed as independent variables, and mental health indicators (depression and stress) were treated as dependent variables. Results: Compared with participants who rarely skipped meals, those who skipped meals occasionally and frequently had significantly higher odds of depression (OR = 1.44, 95% CI 1.23–1.68, p < 0.001; OR = 2.30, 95% CI 1.70–3.10, p < 0.001, respectively). Occasional meal skipping was also associated with higher odds of stress (OR = 1.13, 95% CI 1.01–1.26, p = 0.038), but frequent meal skipping was not significantly associated with stress (OR = 1.27, 95% CI 0.97–1.65, p = 0.080). Irregular meal timing was consistently associated with both depressive symptoms (sometimes irregular: OR = 1.27, 95% CI 1.09–1.49, p = 0.003; irregular: OR = 1.82, 95% CI 1.37–2.41, p < 0.001) and perceived stress (sometimes irregular: OR = 1.35, 95% CI 1.21–1.51, p < 0.001; irregular: OR = 1.42, 95% CI 1.11–1.80, p = 0.005). Gender-stratified analyses showed outcome-specific patterns: frequent meal skipping was strongly associated with depressive symptoms among women (OR = 3.11, 95% CI 1.94–4.98) and was also significant among men (OR = 1.89, 95% CI 1.28–2.80), whereas occasional meal skipping was significantly associated with perceived stress among men (OR = 1.16, 95% CI 1.01–1.33) but not among women. Conclusions: Meal skipping and irregular meal timing were associated with poorer mental health outcomes among people with disabilities. In particular, meal skipping was consistently associated with higher odds of self-reported depressive symptoms, whereas meal regularity was associated with both depressive symptoms and perceived stress. These findings suggest that disability-sensitive nutritional support and integrated mental health interventions may help promote psychological wellbeing among people with disabilities. Full article

Background/Objectives: Within pediatric healthcare systems, integrated strategies combining dietary and oral hygiene interventions have been proposed to improve oral health outcomes. In order to evaluate the effects of combined dietary and oral hygiene approaches on behavioral, knowledge-based, and clinical outcomes in pediatric populations, this systematic review synthesized evidence from intervention studies. Methods: A comprehensive literature search was conducted on 5 September 2025 using PubMed, Scopus, Web of Science, Google Scholar, and arXiv. Children and adolescents (0–18 years old) exposed to dietary and oral hygiene interventions with documented behavioral, clinical, or knowledge-related outcomes were included in eligible studies. Studies were stratified by age groups (0–5, 6–12, and 13–18 years) in order to address developmental heterogeneity. The Cochrane RoB 2 tool for randomized trials and the ROBINS-I tool for non-randomized studies with a comparator were used to evaluate the risk of bias. For single-arm pre–post studies, a narrative risk-of-bias assessment was conducted, as ROBINS-I is not designed for uncontrolled studies. Due to methodological and clinical heterogeneity, a narrative synthesis approach was applied. Results: Out of 1231 records, eight outcome-reporting intervention studies satisfied the inclusion criteria. Improvements in self-reported oral hygiene behaviors, dietary habits, and oral health knowledge were consistently linked to integrated interventions across developmental subgroups. There was little and inconsistent evidence for clinical outcomes, such as caries and periodontal indicators. Conclusions: In pediatric populations, integrated dietary and oral hygiene interventions seem to enhance behavioral and educational oral health outcomes. These findings highlight the need for developmentally tailored preventive strategies integrated within pediatric healthcare frameworks. Full article

Background/Objectives: The global incidence of neuroendocrine tumors (NETs) is steadily rising. While modifiable lifestyle factors impact oncological outcomes, the interplay between dietary habits, orthorexia nervosa (ON) tendencies, physical activity levels (PAL), and body image in NET survivors remains poorly understood. Methods: A cross-sectional study was conducted on a convenience sample of 61 patients with NETs. Validated evaluation tools included the PREDIMED questionnaire for Mediterranean Diet (MD) adherence, the GPAQ for PAL, and the ORTO-15 questionnaire for ON risk. Body image satisfaction and comprehensive clinical features were also assessed. Results: Most participants (75.4%) demonstrated moderate MD adherence. Body image dissatisfaction (32.8%) was significantly associated with a higher BMI (28.86 vs. 24.93 kg/m², p < 0.01) and reduced PAL (660.0 vs. 1680.0 MET-min/week, p = 0.021, pFDR = 0.042). Notably, moderate MD adherence was linked to a higher orthorexic risk (corresponding to lower ORTO-15 scores) compared to low adherence (p = 0.032, pFDR = 0.078). Somatostatin analog therapy showed no detrimental impact on behavioral parameters (p > 0.05). Conclusions: These findings highlight specific vulnerabilities in NET patients: body image dissatisfaction correlates with higher BMI and lower physical activity, while moderate Mediterranean Diet adherence associates with orthorexic risk, which is localized and was not independent in multivariate analysis. Targeted nutritional and physical activity interventions should be integrated into multidisciplinary NET care. Full article

Pollen–food allergy syndrome is an IgE-mediated allergic condition resulting from cross-reactivity between pollen allergens and homologous proteins present in plant-derived foods. PFAS typically presents with rapid-onset itching, burning, swelling, and erythema of the oral cavity and pharynx, with symptoms usually limited to the oropharyngeal region, although systemic reactions, including respiratory or gastrointestinal symptoms and, rarely, anaphylaxis, may occur. PFAS is strongly associated with the atopic phenotype and frequently coexists with allergic rhinitis, atopic dermatitis, and asthma. Available studies show marked variability in prevalence, from a few percent in general pediatric populations to 50–80% among atopic children, especially those with allergic rhinitis, with regional differences likely reflecting pollen sensitization patterns and dietary habits. The aim of this review was to summarize current knowledge regarding the epidemiology, clinical characteristics, molecular determinants, and food-related aspects of PFAS in children across different regions of the world. PFAS is a common but still insufficiently studied condition in children. Standardized diagnostic criteria and large population-based studies incorporating molecular diagnostic approaches are needed to better define the true burden, risk factors, and clinical spectrum of PFAS in childhood.

Background: Carcinogenic polycyclic aromatic hydrocarbons (PAHs), particularly benzo[a]pyrene (BaP) and the EFSA-recommended PAH4 index (benzo[a]pyrene, benzo[a]anthracene, benzo[b]fluoranthene, and chrysene), can accumulate in human breast milk following maternal exposure. Aim: This study aimed to determine BaP and PAH4 levels in breast milk samples of lactating mothers in Hungary and to evaluate demographic, lifestyle, dietary, and environmental predictors of these carcinogenic PAHs. Methods: Breast milk samples (n = 50) were analyzed using high-performance liquid chromatography with fluorescence detection (HPLC/FLD). Due to the right-skewed distribution of PAH concentrations, BaP and PAH4 values were log10-transformed before statistical analysis. Associations between log10-transformed PAH concentrations and maternal variables were assessed using t-tests, Pearson correlation, and multivariable linear regression. Results: BaP was detected in 32 of 50 samples (64%), whereas PAH4 was detectable in 44 of 50 samples (88%). Frequent milk consumption was independently associated with higher log10-transformed PAH4 concentrations in multivariable analysis. Samples collected during the heating season tended to show higher carcinogenic PAH levels compared to those obtained outside the heating period. Other demographic and lifestyle factors showed no consistent independent associations. Conclusions: Lifestyle and environmental factors, particularly dietary habits and seasonal exposure, contribute to carcinogenic PAH levels in breast milk among Hungarian mothers. Identifying modifiable determinants may support strategies to reduce infant exposure. Full article

(1) Background: Adolescence is a critical period for the development of health-related behaviors, including dietary habits and physical activity. This cross-sectional study examined the associations between participation in organized sports, nutrient intake, and body composition in a sample of Greek adolescents. (2) Methods: A total of 224 adolescents aged 12–18 years from schools in the Attica region, Greece, participated in the study. Physical activity and organized sports participation were assessed using a validated questionnaire. Body composition was estimated using bioelectrical impedance analysis, and dietary intake was evaluated using three-day self-reported food records analyzed with Cronometer^® nutrition analysis software. (3) Results: Boys had higher fat-free mass and basal metabolic rate and lower fat-mass percentage than girls. Organized sports participation was common and differed by sex, with boys reporting higher participation and greater adherence to physical activity recommendations than girls. Organized sports participation was associated with differences in selected nutrient intakes, particularly among late adolescents; however, several differences were attenuated when nutrient intake was standardized per 1000 kcal, suggesting that part of the observed pattern may reflect differences in total energy intake. (4) Conclusions: These cross-sectional findings suggest that age-defined adolescent stage and organized sports participation are associated with differences in sports involvement, body composition, and nutrient intake among Greek adolescents; however, causal relationships cannot be established, and the findings should be interpreted as associations.

African pygmy hedgehogs (APHs) are increasingly kept as companion animals, yet evidence-based nutritional recommendations for this species remain limited. Commercial cat or kitten diets are still commonly used by owners and veterinarians in practice, despite being formulated exclusively for domestic cats rather than for hedgehogs with omnivorous–insectivorous feeding habits. This cross-sectional study evaluated the association between dietary regimen and serum biochemical parameters associated with renal function in APHs. Blood samples were collected from 19 client-owned APHs aged 12–68 months: 10 hedgehogs fed a commercial kitten diet and 9 fed a commercial APH-specific diet. Serum concentrations of blood urea nitrogen, creatinine, phosphorus, and calcium were measured, and the nutritional composition of the two diets was compared using manufacturer declarations and targeted laboratory analyses. Hedgehogs fed the commercial kitten diet had significantly higher serum blood urea nitrogen (p = 0.0133), creatinine (p = 0.0279), and phosphorus (p = 0.0279) concentrations than those fed the APH-specific diet, whereas serum calcium concentrations did not differ significantly (p = 0.3846). These differences occurred despite similar dietary phosphorus content, while the commercial kitten diet had higher declared fat and lower fiber content. The findings suggest that dietary regimen may be associated with alterations in renal biochemical profiles in APHs and support the use of species-appropriate diets in clinical practice. Full article

Introduction: Breast milk is the best food for a growing infant during the first 6 months of life. The presence of trans fatty acids (TFAs) in breast milk can interfere with the synthesis of long-chain polyunsaturated fatty acids (LC-PUFAs), increasing the risk of developing, among other issues, asthma or atopic dermatitis. TFAs are not synthesised de novo in the human body. Their content in breast milk may be a good marker of short-term dietary intake of these compounds by breastfeeding mothers. However, the literature shows differences in the assessment of the relationship between dietary TFAs intake and TFAs content in breast milk. Furthermore, the decrease in the TFAs content in food observed recently seems to make it impossible to use Craig-Schmidt’s formula to estimate the TFAs content in the diet or in breast milk. The aim of this study was to confirm the possibility of using TFAs content in breast milk as a marker of their short-term intake within the breastfeeding mother’s diet, together with an attempt at preliminary quantitative determination of the relationship between these parameters. Materials: The study material was collected from a single breastfeeding mother and included 10 breast milk samples and 10 samples of daily food rations reconstructed based on the 24 h food consumption survey. Methods: The content of fatty acids, including TFAs, was determined by gas chromatography–mass spectrometry (GC-MS). Results: The TFAs content in the whole-day mother’s diet and in 100 mL of breast milk ranged from 0.11 to 0.54 g/day and from 0.02 to 0.07 g, respectively. A strong statistically significant (p < 0.05) positive correlation between these parameters was found. Equations for an exploratory linear relationship between the TFAs content in a breastfeeding mother’s diet and the concentration of these fatty acids in breast milk have been developed. Due to the small number of samples, these data should be interpreted very cautiously and validated in a larger cohort. Conclusions: This single-participant pilot study suggests that TFAs content in breast milk may be a marker of the dietary intake of these compounds from the previous day. It seems that the dietary habits of breastfeeding mothers of twins are a significant factor influencing the composition of breast milk and, consequently, the nutritional quality of breastfed infants.

Background/Objectives: Dietary habits are important modifiable factors influencing survival among cancer patients. The dietary quality among cancer survivors may differ from those of the general population and may vary according to age at cancer diagnosis. This study aimed to compare dietary quality between cancer survivors and the general population and to examine whether age at diagnosis is associated with dietary quality. Methods: This retrospective cross-sectional study used data from 8706 adults aged ≥ 30 years (641 cancer survivors and 8065 controls) from the 2019–2021 Korea National Health and Nutrition Examination Survey. Dietary quality was assessed using the Diet Quality Index-International (DQI-I; range 0–100). Survey-weighted multiple linear regression models were used to compare DQI-I scores between cancer survivors and controls. Subgroup analyses were stratified by age at diagnosis, and quadratic age terms were included to assess nonlinear associations. All analyses accounted for the complex survey design. Results: Cancer survivors had significantly higher mean DQI-I scores than controls (69.1 ± 0.4 vs. 66.1 ± 0.2; p < 0.001). Among survivors diagnosed before age 50, dietary quality was significantly higher in those currently under 65 years than in controls (mean difference +3.02, 95% CI 1.44–4.60), but notably lower in those aged ≥ 65 years (−3.18, 95% CI −6.16 to −0.20). In contrast, survivors diagnosed at age ≥ 50 consistently showed higher dietary quality than controls across all age groups (+3.76, 95% CI 2.83–4.68). Conclusions: While cancer survivors generally exhibit better dietary quality than the general population, this positive trend was not observed among younger-onset survivors in older age groups. These findings suggest that age at cancer diagnosis may be associated with dietary quality and highlight the need for sustained, age-specific nutritional support strategies in cancer survivorship.

Background/Objectives: Infertility is a multifactorial condition influenced by both medical factors and lifestyle-related determinants, including diet quality and nutritional supplementation. However, it is unclear which dietary patterns are optimal for women requiring assisted reproductive technology (ART). This study had two main objectives: (1) to assess dietary habits and the prevalence of nutritional supplementation among women with fertility disorders preparing for in vitro fertilization (IVF); (2) to develop, based primarily on a review of the scientific literature, a nutritional protocol to support women undergoing assisted reproductive procedures. Methods: A cross-sectional study was conducted among 61 women undergoing IVF treatment. Diet quality was assessed using the original ProFertiMed score (food-based score). Data regarding supplementation practices, anthropometric characteristics, and the number of IVF attempts were collected using a structured questionnaire. Statistical analyses (Chi-square test) were performed to evaluate associations between diet quality, supplementation practices, and clinical outcomes. Results: Only 8% of the respondents demonstrated a high level of dietary adherence according to the ProFertiMed score, suggesting that nutritional intervention should be implemented in the remaining 92% of women. Dietary supplement use was highly prevalent (95%), with participants taking a mean of 7 ± 4 supplements (range: 1–17). No statistically significant association was observed between diet quality assessed using the ProFertiMed score and the number of IVF attempts (Chi-square test, p = 0.85). Conclusions: The ProFertiMed score appears to be a promising tool for assessing diet-related factors in the context of assisted reproduction and may be particularly valuable when applied at the time of female infertility diagnosis, allowing for the early identification and modification of dietary factors that may affect reproductive outcomes. The proposed protocol, which is primarily based on the scientific literature, outlines key aspects of supportive nutritional management that may contribute to preconception preparation; however, its potential impact on IVF outcomes has not yet been empirically confirmed and should be evaluated in future studies. Therefore, further refinement and validation are required before its implementation in clinical practice. Full article

Hepatitis E virus (HEV) is an emerging zoonotic pathogen in Europe, mainly transmitted via consumption of naturally contaminated food or contact with infected animals. People living in the Balkans have diverse dietary habits, with high pork consumption in some countries, making this region a relevant setting for investigating HEV seroprevalence and its possible determinants. The current study aimed to estimate pooled HEV seroprevalence among adults in the general population and blood donors and to assess factors associated with regional variation. Twenty-eight eligible studies were identified from PubMed, Scopus, and Web of Science following the PRISMA guidelines. Pooled prevalence estimates were calculated using a random-effects meta-analysis of proportions implemented via a generalized linear mixed model (GLMM) with logit transformation. Potential factors associated with HEV seroprevalence, including national pork consumption, serological assay type, population group, year of publication, sex, and country, were evaluated. The pooled anti-HEV seroprevalence was estimated to be 5.68% (95% CI: 3.48–9.12%), with substantial heterogeneity. Country-specific estimates ranged from 1.01% in Greece to 26.66% in Bulgaria. Subgroup analyses showed significant variation according to national pork consumption category, serological assay type, year of publication, and country. However, meta-regression indicated that methodological and temporal factors, particularly serological assay type and year of publication, were the main significant moderators, whereas national pork consumption was not independently associated with seropositivity. Therefore, pork consumption should be interpreted as an exploratory ecological indicator rather than as evidence of a direct association. The methodological differences contribute substantially to the variability in HEV seroprevalence across the Balkans, emphasizing the need for standardized diagnostic approaches within a One Health framework.

Background: Vitamin D is involved not only in calcium–phosphate homeostasis but also in immune and endothelial regulation. Vitamin D deficiency has been suggested to worsen disease activity in systemic lupus erythematosus (SLE). Environmental and lifestyle factors, including seasonal sun exposure, smoking, diet, and supplementation, may influence vitamin D status and disease manifestations. This study aimed to evaluate the association between serum 25-hydroxyvitamin D [25(OH)D] levels, disease activity, and anti-double-stranded DNA (anti-dsDNA) antibody titers in patients with SLE, taking selected lifestyle and environmental factors into account. Methods: Serum 25(OH)D concentrations, SLE disease activity assessed by the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score, and anti-dsDNA antibody titers were measured in patients with SLE and healthy controls. Blood samples were collected during sunny (April–September) and non-sunny (October–March) months. Information on vitamin D supplementation, smoking status, and dietary habits was obtained using a structured questionnaire. Associations between vitamin D status, disease activity, anti-dsDNA seropositivity, season of blood collection, supplementation, smoking, and diet were analyzed statistically. Results: Patients with SLE had significantly higher mean serum 25(OH)D levels than controls, mainly due to frequent vitamin D supplementation. No significant associations were observed between serum 25(OH)D levels and SLEDAI-2K scores or anti-dsDNA antibody positivity. Seasonality, smoking status, and adherence to special diets were not significantly related to disease activity or anti-dsDNA seropositivity. Vitamin D supplementation was strongly associated with sufficient 25(OH)D levels but did not translate into reduced disease activity or lower anti-dsDNA prevalence. Conclusions: Serum 25(OH)D concentration was not associated with clinical or immunological activity of SLE in this cross-sectional study, despite effective correction of deficiency through supplementation. These findings likely reflect the heterogeneity of SLE and the limitations of single time-point assessments, although regular monitoring and individualized vitamin D supplementation may still be considered in SLE care, particularly in the context of recommended photoprotection.

The increase in the prevalence of non-communicable diseases globally has been attributed in part to poor lifestyle choices, including unhealthy dietary habits. Dietary polysaccharides, including resistant starch and non-starch polysaccharides, have gained increasing attention due to their potential role in the regulation of glucose and lipid metabolism. Therefore, the aim of this review was to evaluate the role of dietary polysaccharides in the regulation of blood glucose and lipid parameters. Method: A narrative review approach was adopted for this review. Searches were conducted through EBSCOHost and involved the following databases: Medline, APA PsycInfo, CINAHL Plus with Full Text, Psychology and Behavioural Sciences collection, Academic Search Premier and APA PsycArticles. Searches were conducted on 14 April 2026 and covered all records available from database inception to the search date. Search terms were combined using Boolean operators (AND/OR). The reference list of articles was also searched for more articles. Results: Twenty-one studies from thirteen different countries were included in this review. Based on narrative synthesis, five themes were identified: the effects of dietary polysaccharides on glycaemia, insulin, lipids, energy intake and satiety/appetite. The findings demonstrated considerable heterogeneity across studies. While several studies reported improvements in fasting glucose, postprandial glucose, glycated haemoglobin and insulin responses following resistant starch and non-starch polysaccharide interventions, other studies found no significant effects on glycaemic control or insulin levels. Lipid outcomes were similarly inconsistent, although some studies reported reductions in total cholesterol and low density lipoprotein cholesterol. Effects on energy intake and satiety varied according to the type and physicochemical characteristics of the polysaccharide investigated. Conclusion: The findings of this review suggest that dietary polysaccharides may contribute to improvements in glucose control and lipid metabolism, although the magnitude and consistency of these effects vary across populations, intervention types and study designs. The most frequently reported beneficial findings related to blood glucose parameters, although substantial heterogeneity remained across studies. Further, well-designed studies, including randomised controlled trials with longer durations, are needed to fully establish the role of dietary polysaccharides in the control of blood glucose and lipid parameters.

Background/Objectives: Nutrition during childhood and adolescence is a key determinant of long-term health, influencing metabolic homeostasis, neurocognitive development, and immune system maturation. Globalization and technological advances have reshaped food production and consumption, increasing the availability of ultra-processed foods (UPF) of low nutritional quality. This study aimed to investigate the relationship between parental factors, namely food literacy, perceived barriers and enablers, dietary attitudes, and healthy eating behaviors, and the consumption of discretionary UPF among children and adolescents living in 5 Mediterranean countries. Methods: This cross-sectional study was based on a survey completed by 2011 parents of children and adolescents aged 6–17 years from 5 Mediterranean countries, who reported on their children’s dietary and lifestyle habits. Adherence to the Mediterranean diet was assessed through the KIDMED index. Parental food literacy was measured using the Short Food Literacy Questionnaire (SFLQ). Perceived barriers and enablers were assessed based on the Theory of Planned Behavior, and parents’ attitudes toward their child’s diet were evaluated using the Healthy-Eating Attitudes Questionnaire (HEAQ). Finally, the Theory of Internet Use Related to Health (TIUH) questionnaire was used to assess parents’ tendencies related to health information use online. Results: Higher perceived barriers and enablers were significantly associated with lower discretionary UPF consumption across all models. Parental food literacy (SFLQ) showed a positive association with discretionary UPF consumption, remaining significant in the fully adjusted model, although with reduced magnitude. Healthy-eating attitudes (HEAQ) were initially positively associated with discretionary UPF intake but lost statistical significance after full adjustment. Regarding health-related internet use (TIUH), the Health Information dimension showed a strong positive association with discretionary UPF consumption, while other dimensions (Consciousness and Beliefs) showed inconsistent and non-significant associations in the fully adjusted model. Conclusions: Children’s consumption of discretionary UPF is shaped by several interrelated factors, such as family environment, eating patterns, and parents’ perceptions, rather than solely by knowledge or attitudes.
