The present study aimed to investigate the migration of potentially hazardous compounds from plastic food packaging into edible oils, bottled water and soft drinks available on the market in the Republic of Moldova. GC–MS screening was applied to identify plastic additives and unintentionally added substances (NIAS). The influence of key extraction parameters, including solvent type, extraction time, pH, alcohol content and sugar concentration, was systematically investigated. The optimized procedure demonstrated satisfactory analytical performances, with recoveries ranging from 81 to 96%, repeatability below 5% and detection limits between 0.006 and 0.01 mg/L. To allow a comprehensive assessment of total phthalate contamination, an additional analytical approach based on the hydrolysis of phthalate esters and the determination of o-phthalic acid using capillary electrophoresis with spectrophotometric detection was proposed. The method showed a linearity range of 0.1–5.0 mg/L and a limit of quantification of 0.07 mg/L. The combined chromatographic and hydrolysis-capillary electrophoresis approaches provide a reliable tool for the integrated determination and evaluation of phthalate residues in aqueous-alcoholic systems and beverages, accessible to laboratories performing food quality control.

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

This study evaluated the potential protective effect of a synthesized self-antibacterial nano-hydroxyapatite (nano-HA) toothpaste against erosive changes in the enamel surface induced by a cola-based soft drink, based on a qualitative scanning electron microscopy (SEM) study, in comparison with conventional fluoride toothpaste. Thirty extracted human premolars were sectioned to obtain enamel specimens and randomly assigned into a control group and experimental groups in which fluoride or synthesized nano-HA toothpaste was applied either before or after cola exposure (n = 5 per group). Enamel surface morphology was qualitatively assessed using SEM, and surface roughness (Ra) was estimated using a semi-quantitative approach based on SEM image analysis using ImageJ software. Antibacterial activity was evaluated using the agar diffusion method to explore the potential additional benefits of the synthesized self-antibacterial nano-HA formulation. SEM observations showed that, after cola exposure, specimens treated with nano-HA exhibited less surface erosion than fluoride-treated groups. Post-treatment with nano-HA results in a denser and more uniform surface layer with fewer structural defects. Similarly, enamel treated with nano-HA after cola exposure showed a statistically significant reduction in surface roughness compared with the fluoride group (p < 0.05). These findings suggest that nano-HA provides greater protective effects against acid-induced enamel surface erosion. Furthermore, nano-HA indicated potential antibacterial activity against S. aureus and E. coli. Overall, nano-HA toothpaste provided enhanced protection against acid-induced enamel erosion with additional antibacterial effects. Full article

Background and Objectives: Gastroesophageal reflux disease (GERD) is a prevalent gastrointestinal disorder that significantly affects quality of life. Night eating syndrome (NES), characterized by evening hyperphagia and nocturnal eating, may worsen reflux through delayed gastric emptying and increased nocturnal acid exposure, yet evidence in young adults remains limited. This study aimed to estimate the prevalence of GERD and NES, examine their association, and identify clinically relevant predictors among adults in southern Saudi Arabia. Methods: A cross-sectional study was conducted among 831 adults (≥18 years) in the Jazan region between November 2024 and April 2025. Data were collected using a validated 54-item online questionnaire assessing sociodemographic characteristics, lifestyle behaviors, dietary habits, and medical history. GERD was defined using the GerdQ (score ≥ 8), and NES using the night eating questionnaire (NEQ ≥ 25). Multivariable logistic and linear regression analyses were performed to identify independent predictors. Results: The prevalence of GERD was 25.6%, and 9.7% of participants met the criteria for NES. Higher NEQ scores were independently associated with increased odds of GERD (OR = 1.05, 95% CI: 1.02–1.07; p = 0.001). GERD was predicted by tea consumption, middle income (10,000–14,999 SAR), asthma, hiatal hernia, and a family history of GERD. NES was independently associated with GERD, smoking, and frequent intake of fatty foods, chocolate, salty foods, and soft drinks, while male sex, employment or student status, higher income, and fiber-rich food intake were protective. Conclusions: NES is significantly associated with GERD among young adults. Integrating screening for disordered eating behaviors and dietary counseling into routine GERD care may improve clinical outcomes. Full article

In the context of economic integration and the global trend of sustainable development, sustainability information disclosure is increasingly becoming an essential requirement for businesses. For the listed wine, beer, and soft drink industry in Vietnam (Listed Wine, Beer, Soft Drink Companies: WBDCs), a sector with a significant impact on the environment and society, the Sustainability Report (SR) is not only a communication tool but also a representation of the company’s long-term development strategy. This study aims to identify and measure the extent of influence of internal and external factors on the decision to adopt SR in companies belonging to the WBDCs. Through quantitative surveys and data analysis using the SEM model, the results show that the group of factors related to Enterprise Size plays a decisive role. Additionally, the managerial perspective is also identified as a crucial driver in promoting the transparency of sustainability information. From the research findings, the author team proposes several policy recommendations and orientations to support businesses in enhancing their capacity for sustainability information disclosure, aiming to improve competitiveness and long-term development of the industry in the context of deep integration.

Binary choice models are widely used in econometric modeling when the dependent variable corresponds to discrete outcomes. With appropriate decision rules, these models provide predictions of binary choices generated from predicted probabilities. The accuracy of these predictions in terms of classifying probabilities to events that occurred versus those that did not is a key issue. The use of expectation-prediction success at present is the standard method used to assess the accuracy of these predictions. However, this method is limited in its ability to correctly classify probabilities in the absence of appropriate predetermined cut-off levels. We propose alternative methods to classify probabilities generated through binary choice models, namely resolution graphs and resolution regressions that measure the ability to sort predicted probabilities against observed outcomes. Using probabilities generated from the use of logit models applied to purchasing decisions of various non-alcoholic beverages made by U.S. households, we compare probability sorting power using expectation-prediction success as well as resolution graphs and resolution regressions. Based on expectation-prediction success, the logit models performed better at classifying outcomes related to purchasing isotonic drinks, regular soft drinks, diet drinks, bottled water, and tea. Based on resolution regressions, the null hypothesis of perfect sorting of probabilities was rejected for all non-alcoholic beverages. Although the logit models generated upward-sloping resolution graphs as expected, they were relatively flat compared to the 45-degree perfect sorting line. Going forward, we recommend using resolution regression and resolution graphs to capture sorting of probabilities in addition to the conventional metrics used in ascertaining the ability of binary choice models to predict out-of-sample behavior.

Background and Objectives: This study aimed to evaluate and compare the effects of immersion and brushing on resins used for temporary crowns, including two 3D-printed resins (Nanolab and PrintaX) and one self-curing resin (Duralay), with different surface finishing protocols. Materials and Methods: Printed specimens were designed using specialized software, followed by slicing and printing. Self-curing resin samples were fabricated using silicone matrices, with the printed specimens serving as references. Square samples (7.0 × 7.0 × 2.0 mm, n = 90) were divided into three groups based on surface finishing: extrinsic pigment with glaze, glaze only, and polish only. The samples were immersed in 15 mL of cola soft drink, energy drink, or distilled water for six days at 37 °C in a dark environment before undergoing a brushing test (180 cycles/minute, 65,700 cycles, 2 N, 37 °C). Color alterations, surface roughness, and Knoop microhardness were then analyzed. Results: Statistical analyses revealed that all factors significantly influenced the tested properties (p < 0.05). Nanolab exhibited the most pronounced color alterations, with ∆E₀₀ values reaching up to 22.21 ± 3.13 in specific conditions (e.g., Glaze, Cola soft drink). It also presented increased surface roughness, particularly when compared to PrintaX. Conversely, Duralay consistently displayed the highest Knoop microhardness changes (e.g., ranging from −1.84 ± 0.36 to 0.47 ± 0.45 in different conditions) across most experimental groups. Polishing consistently provided better outcomes in terms of color stability, surface roughness, and microhardness compared to extrinsic pigment + glaze or glaze-only treatments. The first immersion generally led to the greatest color change. Conclusions: The acidic challenge promoted significant changes in the optical and surface properties of the evaluated resins, increasing ∆E₀₀ and roughness and reducing microhardness to different extents depending on the material. Clinically, these findings highlight the relevance of material selection and limiting exposure to acidic beverages during provisional use. Full article

Background/Objectives: Understanding the purchasing behaviour of sweetened beverages is important, as beverages have been highlighted as a key target for reducing sugar intake. This research aimed to provide a comprehensive understanding of trends in per capita volume sales of non-alcoholic water-based beverages (WBB) in Australia and their contribution to dietary sugars between 1997 and 2024. Methods: Volume sales data for the years 2018 to 2024 (Circana Connect) were integrated with three previously published datasets spanning 1997 to 2018, with adjustments to reflect the total market where applicable. Per capita volume sales were determined using national population data (Australian Bureau of Statistics) for each corresponding year. Linear regression analysis was performed to assess trends in per capita volume sales over time. Sugar contributions of each beverage category were modelled based on representative sugar content data. Results: Total WBB sales showed consistent growth over the 28-year period (1.68 L/person/year, 36.2%). Within this, sales of sugar-sweetened beverages (SSB) declined (−1.08 L/person/year), with a concurrent increase in non-sugar-sweetened and unsweetened beverage purchases (2.74 L/person/year). This transition became more pronounced from 2015 and coincided with a decreased contribution of WBB to dietary sugars (−0.13 kg/person/year, p < 0.001). There was variation in sales and sugar contribution trends by beverage category. Functional beverages (e.g., coconut water, protein water) showed increases in sales and sugar contribution. Conclusions: The last 28 years have seen a trend in beverage purchases away from sugar-sweetened to non-sugar-sweetened and unsweetened varieties. This comprehensive analysis of consumer beverage choices makes a valuable contribution to policy and health-focused food industry initiatives. Full article

Background: Studies outside Japan have linked sugar-sweetened beverage (SSB) intake with weight gain; however, evidence in Japanese adults is scarce, and no study has examined beverage-derived energy in relation to anthropometric indices and handgrip strength. Methods: The participants were employees of Fujita Health University aged 20–39 years (n = 76; male n = 35, average age: 29.97 ± 4.67 years; female n = 41, average age: 27.29 ± 4.53 years). Energy from beverage intake was assessed via the Brief Beverage Intake Questionnaire-15, and energy from alcoholic drinks, milk, SSBs, and total beverages was calculated. The associations of energy from different beverages with nutrient intake, BMI, skeletal muscle mass index (SMI), and handgrip strength were analyzed via ordinary least squares (OLS) regression; quantile regression (QR) and the generalized additive model (GAM) were used for sensitivity analyses. Results: Increased SSB intake was associated with increased BMI (standardized β = 0.35, 95% CI 0.12–0.58, p(OLS) < 0.001; p(QR) = 0.23; p(GAM) < 0.001) and was nonlinearly associated with increased SMI (standardized β = 0.21, 95% CI 0.043–0.37, p(OLS) = 0.02; p(QR) = 0.11; p(GAM) = 0.02), even after adjustment for total energy intake. Modest milk intake was linked to higher protein intake and a higher SMI without a higher BMI (standardized β = 0.18, 95% CI 0.020–0.35, p(OLS) = 0.03; p(QR) = 0.39; p(GAM) = 0.03). Conclusions: A positive association was found between SSB intake and both BMI and SMI and between MILK intake and SMI. Clarification in larger, diverse Japanese populations will be necessary.

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: Food cravings are common with high-palatability foods that are high in sugar and/or fat. Food cues can strongly induce food craving, and heightened food cue reactivity is associated with eating disorders and obesity. Sweet taste signalling is suggested to be an important regulator of appetite and food intake, with sensory-metabolic mismatch potentially relevant for the food craving experience. This study investigated the interaction between taste and food cues and food craving in healthy people with and without ingestion of a sugary drink. Methods: This study had a randomised crossover design with 47 healthy individuals who participated in two experimental trials. Fasted individuals were exposed to food cues, and food craving pre- and post-exposure was measured via a newly validated method using handgrip force as a response modality. This was followed either by ingestion (ingestion trial) or mouth rinse (mouth rinse trial) of a sugary drink and reassessment of food cue craving responses. Continuous interstitial glucose monitoring was performed using a glucose sensor inserted into the upper arm, and a blood sample for leptin levels was taken. Results: A strong food craving response to food cues was bound to the fasted state, while ingestion of a sugary drink blunted food cue reactivity and reduced craving levels. Mouth rinse induced a stable increase in food craving, which reached a maximum after food cues. Interstitial glucose levels over the after-trial periods (incremental area under the curve, iAUC) were significantly higher for the rinse trial day than for the ingestion trial day, which may suggest higher carbohydrate/sugar intake after the rinse trial, while craving levels were associated with iAUC in the rinse trial. Conclusions: Outcomes indicate that taste/flavour in connection with food cues may generate an error signal experienced as food craving, whereas receipt of sugars, with concomitant physiological responses, reduces the signal and diminishes food craving. These results highlight the importance of sensory-metabolic mismatch in the food craving experience. Full article

Dietary pattern characterized by low intake of vegetables and fruits and high consumption of fat, soft drink and desserts are associated with an increased risk of chronic diseases. To investigate the effects of folate status and fructose intake on adenine-induced chronic kidney disease (CKD), seven-week-old C57BL/6 mice were divided into six groups and fed either a control diet (Ctrl), a 26% (w/w) high-fructose diet (Hfru), Ctrl plus 0.15% adenine (Ctrl+ade), Hfru+ade, Hfru with folate deficiency plus adenine (Hfru−f+ade), or Hfru with tenfold folate supplementation plus adenine (Hfru+f10+ade). After 10 weeks on the assigned diets, adenine was administrated to the +ade groups for 7 weeks. The results showed that all adenine-treated mice exhibited increased fasting blood glucose, urinary glucose, and elevated renal expression of collagen 1a1 (Col1a1), fibronectin (Fn1), and smooth muscle α-actin (Acta2). Compared with Ctrl mice, Hfru-fed mice showed significantly higher serum creatinine, increased urinary protein, and reduced creatinine clearance. Adenine induced kidney injury in all +ade groups, with the most severe damage observed in Hfru−f+ade mice, as indicated by elevated blood urine nitrogen (BUN), urinary protein, neutrophil gelatinase-associated lipocalin (NGAL), and renal fibrosis. In contrast, Hfru+f10+ade mice showed the lowest levels of these renal injury markers. The Hfru+ade diets increased renal Hif1α and iNos gene expression, which was further exacerbated by folate deficiency. Secretion of the anti-inflammatory cytokine interleukin (IL-10) by splenocytes was significantly reduced under folate-deficient conditions. Renal IL-10 levels were suppressed in all +ade groups but were significantly increased by folate supplementation. Renal IL-10 levels were negatively correlated with the inflammatory chemokine monocyte chemoattractant protein (MCP-1) and transforming growth factor (TGF)-β, whereas renal MCP-1 levels showed positive correlations with TGF-β and IL-6. Overall, these findings suggest that high fructose consumption in the absence of adequate folate intake may be of concern for CKD progression. 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.

The widespread presence of nanoplastics (NPs) in the environment creates a significant and growing concern for global health, with ingestion, inhalation, and dermal contact identified as primary exposure pathways. Despite their documented presence in various environmental matrices and human tissues, robust quantitative data on NP levels remains scarce. This study addresses this critical gap by employing a novel and rapid flow cytometry technique to quantify nanoplastic concentrations in commercial waters, common beverages and infant food, with special focus in packaging influence. Pyrogen-free water was analyzed to establish the negative control for NP concentration, yielding 5.24 ± 2.02 events/µL. Ten commercial waters from natural springs in Spain and France showed NP levels ranging from 1.75 NP/µL to 67.94 NP/µL (mean: 19.90 ± 14.53 NP/µL), where three of those brands showed significantly higher NP numbers than the pyrogen-free water control. Compared to pyrogen-free water, infant formula and cereal porridge showed very low NP concentrations, with values of 10.27 ± 6.85 and 6.78 ± 2.27 events/µL, respectively, following triplicate analyses of six samples. Additional analyses comparing three similar soft drinks across different packaging (can, plastic bottle, or glass bottle) found no significant differences in NP concentration attributable to the container type. NPs, as ubiquitous contaminants, can be ingested by organisms through food and drink. Potential NP contamination in commercial water may be due to factors such as source water contamination, filtration and packaging. The presence of very low concentrations of NPs in infant foods suggests rigorous and effective quality control. Finally, the presence of NP in soft drinks was not affected by the type of packaging. Although soft drinks have higher NP levels than water, the type of packaging had no effect on the presence of NP in these soft drinks. Despite all plastic bottles being made of polyethylene terephthalate, variation in NP accumulation implies that material quality, storage condition, and substantially, water treatment and filtering processes contribute to NP contamination. This research gives evidence for widespread nanoplastic accumulation in bottled water, common beverages and infant formula and sets the stage for demanding research to further investigate sources, health effects, and development into effective quality control and preventive measures for public health.

Following the drinking water crisis induced by harmful algal blooms in Lake Taihu in 2007, industrial restructuring and systematic pollution treatment projects were synchronously conducted to control pollutions in Lake Taihu basin. This paper conducts a systematic review of integrated pollution governance in the Lake Taihu Basin to conduct an exploration of sustainability in developing areas. Critical assessment of the conceptual frameworks and implementation strategies from the aspects of governance concept, technology application and environmental benefits have been made through multi-year water quality monitoring. The results showed that the total nitrogen (TN) and total phosphorous (TP) loads entering the lake decreased by 45.6% and 36.6% in 2008–2023, and the water quality of Lake Tiahu and all 15 major inflow rivers met or exceeded Grade III standards in 2024, according to the National Standard for Surface Water Quality. The lake ecosystem has showed signs of restoration via a decline in the extent and intensity of toxic cyanobacterial bloom. At same time, the local economics have been developed without halting due to the pollution governance, which demonstrates a feasible pathway for both pollution management and economic development. This synergistic governance with both soft and hard measures implemented in Lake Taihu basin has reference significance for other developing countries toward sustainability around the world.
