Background/Objectives: Sensory processing disorders (SID) are common in children with autism spectrum disorder (ASD) and can influence children’s eating behaviors. Evaluating the nutritional status of children with ASD is crucial for families or caregivers to manage their feeding. Therefore, this study aimed to compare the eating behaviors and dietary intake between children with ASD and children with ASD + SID. Methods: This cross-sectional study included 72 children with ASD aged 6–15 years, of whom 36 also had SID. Sociodemographic information and dietary habits of children were collected. The children’s body weight and height were measured. Children’s eating behaviors were assessed using the Children’s Eating Behavior Scale. Dietary intake was obtained using 3-day food consumption records. Results: The rate of overweight was higher in children with ASD compared to children with ASD + SID, but there was no statistically significant difference between the groups (p > 0.05). Children with ASD + SID were more likely to skip main meals than children with ASD (p < 0.05). Children with ASD + SID had significantly lower dietary reference intake levels of energy, macronutrients, fiber, PUFAs, vitamin E, B1, B6, folate, potassium, calcium, magnesium, phosphorus, and iron compared to children with ASD (p < 0.05). Increased scores on the drinking passion subscale were identified as a risk factor for SID (OR = 2.15, 95% CI [1.30, 4.30], p = 0.005). Conclusions: The higher frequency of skipping main meals, significantly lower energy and nutrient intake in the ASD + SID group indicates that these children are at higher nutritional risk. Incorporating sensory-based assessments and interventions into nutritional management may be crucial. Full article

Tea (Camellia sinensis L.) infusion is the second most commonly consumed drink in the world after water, valued for its sensory qualities and health-promoting properties. Tea contains a range of chemical compounds that give it specific nutritional and refreshing properties. These include alkaloids, polyphenolic compounds, carbohydrates, amino acids, enzymes, and aromatic compounds. The content of individual compounds in tea leaves is impacted by factors such as the variety, region, and cultivation method, as well as specific processing operations. The aim of the present study was to investigate the content of bioactive compounds in a selection of organic and conventional tea infusions characterized by different degrees of leaf fragmentation. The analysis of selected phenolic acids, catechins, quercetin, and caffeine in black tea and black Earl Grey tea infusions was conducted using high-performance liquid chromatography (HPLC). The study confirmed that the chemical composition of tea infusions is significantly impacted by the type of tea, cultivation practices, and form of the leaves, and revealed some previously underexplored interactions between the leaf fragmentation and cultivation system effects. From a consumer or product design perspective, organic loose-leaf Earl Grey teas appear to offer the most favourable balance of catechins, and flavonoids whereas conventional bagged black teas provide higher phenolic acid content.

Background: Adolescence is a critical developmental period during which dietary habits are formed and may influence long-term health outcomes. Monitoring changes in adolescents’ eating behaviors and nutrition-related knowledge over time is important for developing effective health promotion strategies. The aim of this study was to compare adolescents’ (Lower Silesia, Poland) dietary habits and nutritional knowledge between two study periods (2011 and 2023) using comparable survey methods. Methods: A repeated cross-sectional comparison of two independent cohorts was conducted using an identical questionnaire in both study periods. The 2023 cohort included 14-year-old primary school students (n = 100; 48 girls and 52 boys), while the comparison group consisted of adolescents aged 13–15 years assessed in 2011 (n = 377; 202 girls and 175 boys). Anthropometric measurements and self-reported data on dietary habits and nutritional knowledge were analyzed using descriptive statistics and group comparison tests. Results: The findings indicate changes in selected dietary behaviors and levels of nutritional knowledge among adolescents over the studied period. A higher percentage of students in 2023 reported eating four meals per day and obtaining information about healthy eating from the Internet rather than from television. Students in 2023 were also more likely to recognize the relationship between diet and attention, identify the harmful effects of energy drinks and excessive fast-food consumption, and provide correct answers regarding proper nutrition. Nutritional knowledge improved over time, with a mean percentage of correct responses of 71.9% in 2023 compared with 63.7% in 2011. Although nutritional awareness improved in several areas, certain unhealthy eating habits remained prevalent, including irregular breakfast consumption and frequent intake of sweets. Changes in the distribution of body weight categories were also observed, with gender-specific differences between cohorts. Conclusions: The results suggest that improvements in nutritional knowledge alone may not be sufficient to ensure positive changes in dietary behavior among adolescents. Continued monitoring of adolescent nutrition and the development of comprehensive health promotion strategies addressing both knowledge and environmental influences remain necessary. Full article

Background: Leading sports medicine and nutrition organizations recommend replacing sodium losses during prolonged exercise; however, practical guidance for implementing sodium replacement strategies remains limited. Estimating sodium needs during exercise requires assessment of both whole-body sweat sodium concentration (WBSSC) and sweat rate. Objectives: This study focused on WBSSC by examining its temporal stability, reproducibility, and predictability during prolonged cycling exercise while drinking according to two hydration strategies. Methods: Using a randomized, crossover, counterbalanced design, eight highly trained men completed two 5 h cycling sessions (183 ± 14 W, 30 °C) while consuming fluids either in a programmed (P) or ad libitum (A_L) fashion. Sweat was collected with patches applied on the forearm for ~20 min before sampling, which occurred at ~40, 130, 220, and 290 min. Local sweat sodium concentration was converted to WBSSC using a validated equation. Results: A main effect of time was observed for WBSSC (p < 0.05), with only the 40 min time point differing from later measurements; no condition or interaction effects were detected. The within-trial typical variation in WBSSC was 7.2 mmol·L⁻¹ for P and 6.1 mmol·L⁻¹ for A_L, while the between-trial typical variation was 5.6 mmol·L⁻¹. The WBSSC measured at 40 min predicted mean exercise WBSSC with good precision and moderate stability (y = 0.2738 + 1.3397x, R² = 0.87, standard error of the estimate = 5.4 mmol·L⁻¹, 95% confidence interval slope = 0.82–1.86 mmol·L⁻¹). Conclusions: These findings indicate that during prolonged cycling exercise, WBSSC (1) varies trivially within and between trials; (2) can reasonably be predicted using a single sweat sample and; (3) is not influenced by P or A_L drinking.

Background: Parental knowledge and perceptions towards Functional Foods (FFs) play a critical role in shaping children’s dietary behaviors. This study aimed to investigate dietary habits, FFs knowledge and perceptions among Greek primary school children and their parents and to evaluate the feasibility of a one-month pilot asynchronous nutrition education program. Methods: A cross-sectional study included 374 children aged 9–11 years and 159 parents from urban (Thessaloniki) and rural (Lemnos) areas. Children completed questionnaires on dietary habits, FFs knowledge and Mediterranean Diet (MD) adherence (KIDMED score), while parents provided sociodemographic information, BMI, dietary habits, FFs knowledge and perceptions. A pilot asynchronous nutrition education intervention was delivered via pre-recorded videos on FFs, the MD, portion sizes and food label interpretation, with participation tracked and program evaluation conducted among parents. Data was analyzed using IBM SPSS Statistics (version 28). Descriptive statistics were calculated, group differences were assessed with t-tests and ANOVA and associations between variables were examined using chi-square tests and Pearson correlations (p < 0.06). Results: Children showed moderate MD adherence, frequent fast-food and soft drinks consumption and low FF knowledge, with a substantial gap between perceived and actual understanding. Parental FF knowledge was uneven, higher among normal-weight participants and largely limited to fortified products. Positive associations were found between children’s and parents’ diet quality and natural FF consumption, as well as between parental and child physical activity. The asynchronous intervention was positively rated; substantial attrition was observed across sessions and follow-up, which limited the ability to assess the intervention’s effects on behavioral change. Conclusions: This study highlights critical gaps in FFs knowledge among families and demonstrates that asynchronous, family-based nutrition education is feasible but challenged by engagement attrition. Targeted interventions are needed to clarify FF concepts and promote healthier family dietary behaviors. Full article

Background: 3D-printed resin composite and hybrid ceramic materials are widely used in prosthetic dentistry for their esthetic, mechanical advantages, and digital compatibility, though their surface properties may be affected by drinking habits. This study aimed to evaluate the influence of a carbonated nutritional beverage multivitamin drink (Oronamin C) on the surface microhardness, roughness, solubility, and color changes in a recently introduced 3D-printed resin composite (Permanent Crown Resin), hybrid ceramic material (Vita Enamic) and a nanohybrid resin composite (Luna). Methods: A total of 120 disk-shaped specimens were distributed according to the type of material into three groups (n = 40). These were divided into four subgroups of specimens for each test (n = 10). The specimens were examined before and after immersion in Oronamin C solution for 12 days. Results: The results showed that there was no significant change in surface microhardness and surface roughness in both 3D-printed resin composite and hybrid ceramic after immersion, while microhardness decreased significantly in the nanohybrid resin composite with an increase in surface roughness. Solubility increased significantly in the nanohybrid and 3D-printed resin composites, but not in the hybrid ceramic. All materials presented clinically acceptable color changes, with mean values lower for both nanohybrid and hybrid ceramic. Conclusions: This study concluded that the hybrid ceramic and 3D-printed resin composite exhibited good stability after Oronamin C beverage exposure, whereas the nanohybrid resin composite exhibited the most impairment among all materials. All materials demonstrated clinically acceptable color changes. Full article

Common buckwheat (Fagopyrum esculentum Mill.) is a pseudocereal that has recently gained increasing interest among both farmers and scientists. Its low soil requirements, high adaptability, and high resistance to diseases and pests allow it to be cultivated in many regions of the world. It is recommended for various cultivation systems, especially for low-input and organic farming. Currently, buckwheat is grown mainly for seeds and less often for green fodder. Thanks to its above-average nutritional value and many benefits that support human health, it is considered one of the leaders in functional food. It can be a basic raw material for many food products such as flour, groats, and flakes, but can also be used as a valuable addition to crisps, bars and drinks. Recently, buckwheat’s usefulness in the energy industry, construction, medicine, and pharmacology has been confirmed. Buckwheat, as a plant species distinct from the dominant global crops, fits very well into the current standards and assumptions of sustainable development. Its cultivation and consumption are associated with a number of benefits not only for human health but also for the whole environment. It is considered a species that counteracts climate change. Buckwheat’s valuable properties include its positive impact on soil physicochemical properties, its enhancement of biodiversity, and its support for pollinators. It is considered a species that can be cultivated in a changing climate, generating a very low carbon footprint. The aim of this study was to determine the contemporary economic importance of buckwheat, its place among species supporting sustainable development, and to identify potential research areas that will contribute to strengthening buckwheat’s role in sustainable agriculture.

Objective: To examine the proportion of drinks and snacks offered by the largest coffee shop chains in the UK that exceed the NHS and Public Health England maximum recommended intakes for energy and sugar. Design: Observational study design where nutritional information for drinks and snacks was gathered from the official coffee shop chain website. Data were compared with the maximum recommended intakes of 200 kcal per drink or snack and 30 g of free sugar per day. Direct comparisons between mean values were performed using analysis of variance (ANOVA). Subjects: A total of 2707 drinks and 434 snacks across eight leading coffee shop chains in the United Kingdom. Results: Overall, 47.0% of drinks and 66.8% of snacks exceed the recommended energy intake, while 32.5% of drinks and 45.3% of snacks surpass the recommended daily free sugar intake. ‘Hot chocolates and other speciality drinks’ contain the most energy (255.6 ± 5.78 kcal) of all drink categories. Snacks contain significantly more energy than drinks (p < 0.001), with all three snack categories exceeding the recommended intake of energy. Variations in nutritional content were observed in dairy-alternative milk options and specific chains. Conclusions: The high energy and sugar content of drinks and snacks in major UK coffee chains may contribute to excessive energy intake, with almost half of all drinks and snacks exceeding the maximum recommended levels. Healthier choices, such as avoiding flavoured drinks or limiting the consumption of snacks, may be necessary to help mitigate weight gain and combat obesity and T2DM rates in the UK. Full article

Access to safe drinking water is critical for child growth and development. However, microbial contamination is a constant threat in many low- and middle-income countries. The current systematic review sets out to examine the evidence of drinking water quality and the physical and cognitive development of children aged 0 to 5 years. The review authors conducted a comprehensive search of SCOPUS, EBSCO, PubMed, the Cochrane Library, and Google Search for cohort studies and clinical trials conducted in English between the years 2010 and 2025. Of 222 studies, 15 were included in the review and the majority were conducted in low- and middle-income countries The findings consistently demonstrate that microbiological contamination, predominantly by Escherichia coli (the primary water quality indicator examined across studies), is associated with an increased risk of stunting (odds ratio up to 4.14) and reductions in height-for-age Z-scores (HAZ) (by 0.29–0.57). There is currently limited evidence in the studies reviewed that suggests a correlation between the presence of unsafe drinking water and a decrease in cognitive development; however, the evidence is insufficient and warrants further study. Integrated water, sanitation and hygiene (WASH) and nutrition programs had promising growth results, which varied depending on the initial sanitation coverage of the target population, adherence to the intervention, and the overall design of the program. To sum up, contaminated drinking water negatively affects physical and cognitive development during early childhood. Comprehensive WASH–nutrition strategies need to be implemented to reduce this impact and further progress towards Sustainable Development Goal (SDG) 6. Full article

Background/Objectives: Colombia has implemented a tiered tax on sugar-sweetened beverages (SSBs), reaching 20% for high-sugar products by 2025. To inform evaluations of this policy, we estimated taxed and untaxed beverage intake prior to implementation and examined differences across sociodemographic groups. Methods: We analyzed 24 h dietary recall data from the 2015 National Survey of the Nutritional Situation of Colombia (ENSIN; n = 11,877 adults aged 18–64), which uses a stratified, multistage cluster sampling design covering all regions of the country. Beverages were categorized by 2025 tax thresholds: untaxed (<5 g added sugar/100 mL), taxed (≥5 g), and high-sugar taxed (≥9 g). Intake (mL, kcal) was estimated per capita and per consumer using survey-weighted two-part models, adjusting for sociodemographic characteristics. Results: Eighty-four percent of adults consumed taxed beverages, with per capita intake of 209 kcal (95% CI: 203–216) and 481 mL (95% CI: 464–497). Sixty-three percent consumed high-sugar taxed beverages, with intake of 134 kcal (95% CI: 130–139) and 292 mL (95% CI: 282–303) per capita. Untaxed beverages accounted for 109 kcal (95% CI: 106–112) and 837 mL (95% CI: 793–882) per capita. Across categories, the highest per capita kcal intakes were from untaxed dairy/milk substitutes (67 kcal, 95% CI: 64–69), any taxed fruit/vegetable juices (61 kcal, 95% CI: 55–66), and any taxed sodas/carbonated beverages (47 kcal, 95% CI: 44–50). Males consumed more taxed beverages of any type (255 kcal, 95% CI: 247–264) than females (174 kcal, 95% CI: 165–182). Conclusions: Prior to its SSB tax, Colombians had a high consumption of SSBs that would be subject to the tax. Future research should assess how consumption changed in response to the tax.

Background/Objectives: Among more than 300 candidate genes for obesity, FTO, MC4R, and BDNF have been approved for DTC genetic testing. However, population-specific evidence supporting their relevance to obesity-related phenotypes in Koreans remains limited. Methods: A total of 231 healthy adults aged 19–64 years were recruited between March and May 2024. Anthropometric and clinical measurements, genotyping, dietary intake, and questionnaires on socioeconomic status, family history, and lifestyle behaviors were obtained. Associations between genotypes and obesity-related phenotypes were evaluated using ANOVA and ANCOVA, multivariable-adjusted models and multicollinearity analysis-based stepwise regression. Results: In Koreans, MAFs for FTO (3 SNPs), MC4R rs17782313 and BDNF rs6265 were 13–16%, 27.1% and 47.4%, respectively. OB frequency (%) differed significantly between BDNF GG and A allele carriers (p < 0.05). Compared to GG, BDNF A allele carriers showed higher WHR, ALT, HbA1c and sodium intake (p < 0.05). BDNF A allele carriers were observed to have higher drinking frequency and elevated ALT levels. Significant genotype–obesity interactions were identified for RMR/BW status, dietary fiber, Vit E, folate, P, K, cholesterol, and PUFA (p < 0.05). Among A allele carriers, OB-related indicators (BMI, RMR, WHR) were independently associated with age, sex, RMR, SBP, ALT, leptin, and dietary intakes of Vit A and sugars. Conclusions: These findings support the relevance of BDNF rs6265 in obesity phenotypes among Korean adults and provide Korean-specific evidence for genotype-based nutrition strategies. Given the cross-sectional study, the interpretation of personalized nutrition approaches for genetic risk carriers should be made with caution. Full article

This study aimed to determine the effects of incorporating probiotic fermented natural lactic acid bacteria (PFJ) into the drinking water of laying quails subjected to temperature stress on egg production, egg quality, cecum microbiology, blood parameters, and incubation performance. A total of 260 Japanese quails (Coturnixcoturnix japonica) aged 8 weeks were used, of which 200 were females, and 60 were males. The quails were divided into four groups, each containing 50 individuals, and further split into five subgroups of 10 quails. For every 10 female quails, three male quails were housed together in cages. The experiment was conducted under normal environmental conditions in control, PFJ, heat-stressed control, and heat-stressed PFJ groups. Temperature stress (34–36 °C) was applied for 8 h daily. The results indicated that by the end of weeks 1–4, the feed conversion ratios of all groups were significantly different, with the best feed conversion ratio of 2.36 found in the PFJ group under temperature stress. Throughout the periods of weeks 1–4 and 5–8, there were statistically significant differences (p < 0.01) in the daily average feed consumption and egg weights among all treated groups. Temperature stress and the addition of PFJ significantly affected shell thickness, Haugh units, albumen weight, yolk weight, and yolk color; no significant impacts were observed on egg shape index, yolk percentage (%), albumen percentage (%), and specific gravity (g/cm³). The highest counts of lactic acid bacteria (LAB) were found in the PFJ-treated groups under both normal and temperature-stressed conditions. Under temperature stress, the levels of Enterobacter, coliform, and E. coli decreased with the addition of PFJ. Regarding blood parameters, significant differences (p < 0.05) were observed in total protein values among groups, while differences in chloride, triglycerides, total cholesterol, LDL cholesterol, HDL cholesterol, and triglyceride concentrations were not statistically significant (p > 0.05). Furthermore, the addition of temperature stress and PFJ significantly affected fertility rates, incubation efficiency, and hatchability. In conclusion, these findings suggest that PFJ could be considered a potential probiotic alternative for improving nutrition in laying quails under conditions of temperature stress. Full article

Beverages, particularly sugar-sweetened beverages (SSBs), pose a significant public health concern globally. Changing eating habits among Pakistani young adults have led to higher sugary drink consumption, underscoring the need for a suitable cultural assessment tool. A cross-sectional study was conducted among 381 university students aged 18–26 years from three major cities of Pakistan. Following World Health Organization (WHO) guidelines, the original Beverage Intake Questionnaire (BEVQ-15) was modified by removing four items (including alcoholic beverages), adding two culturally relevant types (flavored milk and refreshing drinks), and converting measurement units to milliliters, resulting in a 13-item Beverage Intake Questionnaire-Pakistan (BEVQ-PK). Validity was assessed by comparing BEVQ-PK1 (test) with three 24 h dietary recalls. Test–retest reliability was evaluated after a 14-day interval by comparing BEVQ-PK1 (test) and BEVQ-PK2 (retest). Analyses included descriptive statistics, paired sample t-tests, Intraclass Correlation Coefficients (ICC), Bland–Altman plots, and Spearman’s correlations. The BEVQ-PK (13-item) demonstrated moderate to strong validity (r = 0.2–0.8, p < 0.001) and strong reliability (r = 0.5–0.9, p < 0.001). Most beverage categories showed no significant intake differences between test and retest. Tea/coffee with milk was the most frequently consumed beverage, followed by soft drinks and green/black tea. Overall, BEVQ-PK is a valid and reliable tool for assessing SSB intake among Pakistani university students and can support future nutrition and public health research. Full article

Background/Objectives: Within public health and preventive nutrition, food labeling plays a critical role in supporting healthier dietary behaviors. This study aimed to evaluate the behaviors, perceptions, and nutritional literacy of young adults from Iași, Romania, regarding simple carbohydrates (SCHO) consumption and food label-reading habits. Materials and Methods: A cross-sectional survey was conducted between May–June 2023 using 20-item Likert-scale questionnaire completed by 150 participants aged 18–30 years. Statistical analysis included descriptive metrics, Chi-square tests, and Pearson’s correlation, with significance set at p ≤ 0.05. Results: The cohort consisted of 72% females (N = 108) and 28% males (N = 42), with 42.7% (N = 64) holding university degrees. Although 22% (N = 33) considered SCHO consumption highly important, only 13.3% (N = 20) frequently read nutrition labels (p ≤ 0.05). Dietary patterns showed that 27.3% primarily consumed sweets, while others combined sweets with carbonated beverages, dairy products, or whole grains; overall, 44% (N = 66) reported frequent sweet consumption. Label reading was highest for sweets (40.7%), lower for dairy products (19.3%) and soft drinks (9.3%). Additionally, 30.7% (N = 46) checked only expiration dates, whereas just 11.3% (N = 17) reviewed nutritional content. Trust in label accuracy was low: 48% (N = 72) expressed neutrality and 14% (N = 21) disagreed. Although 77.3% (N = 116) recognized the link between sugar intake and dental caries, only 23.3% (N = 35) felt well informed about oral health risks. Taste dominated food selection (68.7%), while nutritional value was cited by 16.7% (N = 25). Conclusions: Young adults from Iași demonstrated notable gaps in nutritional literacy and suboptimal dietary behaviors, emphasizing the need for structured educational strategies to improve preventive practices relevant to systemic and oral health.

Pomegranate peel, a rich agro-industrial by-product, contains abundant phenolic compounds with strong antioxidant and antimicrobial properties. However, the low stability and bioavailability of these compounds limit their efficacy in animal nutrition. This study investigated the effects of pomegranate peel phenolic extract (PE), either in raw form (PE300) or nano-encapsulated using gum–gelatin nano-capsules (NPE300), on health and growth parameters in newly weaned rabbits. Fifty-four male rabbits (40 days old) were assigned to three treatment groups: PE0 (control), PE300 (300 mg PE/L drinking water), and NPE300 (300 mg nano-encapsulated PE/L drinking water). Over six weeks, growth performance, hematological and immunological profiles, antioxidant status, microbial populations, and carcass traits were evaluated. NPE300 treatment demonstrated superior antimicrobial activity in vitro, with larger inhibition zones against all tested pathogens compared to PE300. In vivo, NPE300 significantly improved body weight gain (945.8 g) and feed efficiency, while also enhancing immune function, evidenced by higher white and red blood cell counts, phagocytic activity, and increased plasma IgG and IgM levels. Antioxidant markers showed that NPE300 significantly reduced malondialdehyde levels and tended to improve total antioxidant capacity. Furthermore, intestinal Clostridia counts were reduced, and beneficial microflora significantly increased in the NPE300 group. Carcass weight with edible parts, fur weight, kidney weight, and cecum length were also elevated under NPE300 treatment. In conclusion, nanoencapsulation of PE using gum–gelatin carriers enhanced its bio-efficacy, supporting better redox balance, immunity, gut health, and growth performance in rabbits. These findings support the application of nano-encapsulated PE as a promising natural growth promoter in rabbit production. Full article
