Background/Objectives: Overweight and obesity are increasing globally. However, structured contemporary data on lifestyle behaviors and adiposity in Romanian young adults remain limited. Therefore, this study aimed to describe dietary and lifestyle habits, BMI, and overweight/obesity prevalence in Romanian adults aged 18–30 years and to examine associations between these variables. Methods: This cross-sectional online questionnaire study included 1202 young Romanian adults. BMI was calculated from self-reported height and weight and analyzed continuously, as well as for overweight/obesity (BMI ≥25 kg/m²). Pre-specified exposures were compulsive eating, soft-drink intake, breakfast frequency, physical activity, and sleep duration. Multivariable linear regression with heteroscedasticity-consistent standard errors was used for BMI, and modified Poisson regression with robust variance was used for overweight/obesity. Composite dietary score, sex-interaction, and sensitivity analyses were also performed. Results: Mean age was 23.2 ± 3.3 years, mean BMI was 23.8 ± 4.2 kg/m², and 32.4% of participants had overweight/obesity. Men had higher BMI and a higher prevalence of overweight/obesity than women. Compulsive eating and soft-drink intake showed dose-dependent associations with higher BMI and higher overweight/obesity prevalence. Short sleep duration (≤5 h/night) and daily breakfast consumption were associated with a higher and, respectively, lower prevalence of overweight/obesity. Physical activity showed no independent association after full adjustment, although this finding may be influenced by the use of a single self-reported item. Composite-score analyses supported the main findings. Conclusions: In Romanian young adults, compulsive eating and soft-drink intake were the most consistent behavioral correlates of adiposity, while breakfast regularity and short sleep showed threshold-type associations with overweight/obesity. These findings may inform the design of multicomponent prevention strategies, although longitudinal confirmation is needed. Full article

Background: Serum concentrations of 25-hydroxyvitamin D [25(OH)D] are associated with the risk of several chronic and acute diseases. However, updated data on vitamin D status in Mediterranean countries, including Italy, remain limited, hindering effective public health strategies. Objective: To assess serum 25(OH)D levels and their seasonal variation in healthy blood donors aged 18–65 years living in Northern Italy and not taking vitamin D supplements. Given the latitude and the high levels of environmental pollution, cutaneous vitamin D synthesis may be impaired in this population. Recent Italian guidelines on supplementation emphasize the need for updated data on the prevalence of hypovitaminosis D and seasonal variation in endogenous vitamin D synthesis. Methods: In this exploratory retrospective cross-sectional study, 534 blood donors (268 men and 266 women) attending the Transfusion Medicine Unit of the Verona University Hospital were enrolled between April 2016 and May 2018. Serum 25(OH)D concentrations were analyzed by season. Clinical, lifestyle, pharmacological and dietary characteristics were also collected. Results: Among healthy, normal-weight individuals, the prevalence of vitamin D insufficiency (25(OH)D < 50 nmol/L) was low and limited to one-two months per year. Overweight and obesity significantly reduced the likelihood of achieving adequate 25(OH)D levels through cutaneous synthesis for several months. Mean 25(OH)D concentrations were higher than those previously reported in the same area, while seasonal variation remained preserved. Conclusions: In a relatively small non-supplemented population of blood donors living in a high polluted urban area of Northern Italy, seasonal vitamin D synthesis seems to be preserved. These updated data show higher 25(OH)D levels compared to past findings. Although these data certainly warrant further validation through a national survey involving other regions of Italy and in not selected population, they appear to be in line with the SIOMMMS recommendations against indiscriminate serum 25(OH)D testing and against routine supplementation for healthy normal-weight individuals under 70 years.

Congenital heart disease (CHD) is the most common anatomical malformation occurring in live-born infants and an increasing cause of morbidity and mortality all over the world. Population-based observations have described associations between maternal cardiometabolic disorders and the risk of CHD in offspring. The present article is a narrative review. The aim of this study was to review the epidemiological evidence and clinical observations relating maternal obesity and diabetes mellitus to the risk of CHD in offspring, with particular attention paid to first trimester disturbances of fetal cardiac development and the influence of genetic, epigenetic and environmental factors. Studies have shown that maternal diabetes is a risk factor associated with nearly all subtypes of CHDs in offspring, while obesity and overweight are associated with increased risk for complex defects and outflow tract obstruction and decreased risk for ventricular septal defects. Diabetes and obesity share several phenotypes, which could be transmissible from mother to fetus via the placenta. This means that an increase in maternal glucose could be responsible for the prevalence of CHD in newborns of obese women. On the other hand, maternal diabetes may induce epigenetic modifications in the developing fetus. DNA methylation changes can impact gene expression patterns relevant to heart development. The abovementioned studies are heterogenous, express different opinions and are often difficult to compare. Therefore, the results from these meta-analyses must be interpreted with caution. Optimal diabetes control is responsible for the prevention of oxidative stress in diabetic pregnancies, and a deeper understanding of maternal risk factors holds the potential to improve both prenatal detection of CHDs by identifying at-risk pregnancies and primary prevention of diseases by improving preconception management.

Background/Objectives: Breast Milk Feeding (BMF) benefits mother and infant. However, women with select risk factors report shorter breastfeeding durations. Our previous prospective cohort observational study of a lactation-consultant-led telephone-based support program in the first month postpartum increased BMF rates up to 6 months. This post hoc study further evaluated the program for mothers at increased risk of early breastfeeding cessation. Methods: We performed secondary analysis involving 762 mothers (control, n = 378; intervention, n = 384), recruited between 2018 and 2019. Infant feeding types, including BMF, were recorded at 1, 3 and 6 months. Feeding outcomes were analyzed in association with maternal risk factors. p-values, odds ratios and 95% confidence intervals were reported via both univariate (UVA) and multivariate regression analysis (MVA). Results: Via MVA, the intervention was associated with increased 6-month BMF rates in these groupings [OR (95%CI), p-value]: European [1.80 (1.07–2.96), p = 0.027]; South Asian [1.93 (1.19–3.13), p = 0.008]; employed [1.47 (1.02–2.12), p = 0.038]; unemployed [2.15 (1.33–3.50), p = 0.002]; married [1.71 (1.22–2.39), p = 0.002]; social support present [1.51 (1.05–2.16), p = 0.026]; chronic illness [1.93 (1.35–2.75), p = 0.001]; gestational diabetes mellitus [2.17 (1.19–3.95), p = 0.11]; overweight and obese [1.48 (1.03–2.12), p = 0.034]. A derived success score across the study period indicated via UVA associated increases in BMF rates with history of depression and anxiety (MI) [p = 0.044] and ongoing MI [p = 0.033], but these increases were smaller than that for no history of MI [p < 0.001]. No effect was observed in East/Southeast Asian mothers, Middle Eastern mothers, single or de facto mothers, older mothers, mothers without social support and mothers of any skill level. Conclusions: Although early postpartum telephone support was associated with a number of positive findings of improved BMF at 6 months and over the course of the study, the results were mixed. This suggests that future breastfeeding telephone-based initiatives need to be multifaceted in order to target mothers at risk of early breastfeeding cessation. Full article

Background/Objectives: To assess the prevalence of eating disorder (ED) risk in a sample of Italian university students and to examine its independent associations with mental health indicators, self-rated health, body mass index (BMI), lifestyle behaviours, and engagement with digital food-related applications. Methods: Of the 2779 Italian university students who accessed the survey, 2691 completed and were included in the analysis. ED risk was assessed with the validated 5-item SCOFF questionnaire. Exposure included socio-demographics, BMI, depressive symptoms (PHQ-9), self-rated health, adherence to the Mediterranean diet (Medi-Lite), smoking, alcohol use (AUDIT-C), and use of food delivery and food waste apps. Multivariable logistic regression models, stratified by sex, and adjusted by age and education, estimated associations with ED risk. Results: Overall, 34.6% of participants screened positive for ED risk (women 39.5%, men 21.8%). Smoking and use of food delivery apps and food waste apps were independently associated with ED risk. Clinically relevant depressive symptoms (PHQ-9 ≥ 10) (aOR 3.37, 95% CI 2.82–4.02) and poor/fair self-rated health (aOR 2.45, 95% CI 1.93–3.11) showed the strongest association. Overweight (aOR 1.47, 95% CI 1.06–2.03) and obesity (aOR 2.48, 95% CI 1.53–4.01) increased the likelihood of ED risk. Risky alcohol use was also associated (aOR 1.42, 95% CI 1.15–1.75). Conclusions: More than one in three Italian university students is at risk for an ED, highlighting a substantial public health concern. Strong links with depression, perceived poor health, digital food app use, and unhealthy behaviours underscore the need for early screening and integrated mental health and nutrition interventions within university settings.

Bovine colostrum (COL) is widely used in dietary supplements, and previous studies have suggested its potential benefits for immune function, selected clinical conditions, wound healing, and athletic performance. This systematic review analyzed clinical trials published between 2001 and 2025 that investigated the effects of COL on human body fat and blood lipid profiles. The review was conducted in accordance with PRISMA guidelines, and study quality was assessed using Cochrane risk-of-bias tools. Thirteen studies were included. One study in older adults reported that COL supplementation at 60 g/day for 8 weeks significantly reduced body fat percentage by 0.4% (p < 0.05). Another study found that COL supplementation at 10 g/day combined with plant proteins for 12 weeks significantly attenuated the increase in leg tissue fat percentage compared with placebo (PLA) (0.48 ± 1.29% vs. 1.12 ± 1.27%, respectively; p < 0.05). Changes in blood lipid profiles were reported in two studies. In individuals with type 2 diabetes, COL supplementation at 10 g/day for 4 weeks significantly reduced total cholesterol (TC) and triglyceride levels in both men and women, by 8.27% vs. 7.62% and 11.96% vs. 21.46%, respectively. In another study involving older adults, COL supplementation at 30 g/day for 12 weeks significantly reduced TC (5.88 to 5.38 mmol/L) and low-density lipoprotein cholesterol (LDL-C) (3.68 to 3.28 mmol/L) compared with PLA. Owing to substantial methodological heterogeneity and inconsistent findings, further randomized, double-blind trials are needed in larger groups of overweight or obese participants, with intervention periods lasting at least six months. Future studies should use a standardized COL dose of 20–25 g/day, controlled caloric deficits, and a four-arm design comparing placebo and COL under normocaloric and energy-restricted dietary conditions. Assessments should include blood metabolic biomarkers, body composition measured by dual-energy X-ray absorptiometry, gut microbiome composition, and fecal short-chain fatty acids to determine whether any observed benefits are attributable to COL alone or to its combination with dietary intervention.

Background: Underweight status is common among young women in Japan and has been linked to impaired glucose tolerance, but its long-term association with HbA1c trajectories remains unclear. This study examined whether body size history in the twenties is associated with subsequent HbA1c trajectories across adulthood. Methods: We analyzed health check-up data from Fujita Health University, collected between 2003 and 2025. Participants were classified as normal weight in the twenties (NW20s), underweight at least once in the twenties (UW20s_ever), or overweight at least once in the twenties (OW20s_ever), excluding mixed underweight/overweight histories. Eligible individuals had at least 5 years of follow-up, at least five BMI and HbA1c measurements, and at least one BMI record between ages 20 and 29 years. HbA1c trajectories were evaluated using sex-stratified linear mixed-effects models. Kaplan–Meier and Cox regression analyses were used to assess the risk of first reaching HbA1c ≥ 5.6%. Results: A total of 2923 participants were included in the trajectory analysis. For the time-to-event analysis, 2753 participants were included after exclusion of 170 participants with HbA1c ≥ 5.6% at study entry. Body size history in the twenties was associated with distinct, sex-specific HbA1c trajectories. OW20s_ever showed persistently higher HbA1c levels in both women and men, but the local slope of HbA1c was greater at ages 35 and 45 years in women and at age 25 years in men. In contrast, UW20s_ever showed lower HbA1c levels than NW20s at ages 25 and 35 years only in women. In complementary time-to-event analyses, OW20s_ever was associated with a higher risk of HbA1c ≥ 5.6% in both women and men (women: HR 1.37, 95% CI 1.06–1.76, p = 0.016; men: HR 1.81, 95% CI 1.41–2.32, p < 0.001), whereas UW20s_ever was associated with a lower risk only in women (HR 0.81, 95% CI 0.67–0.98, p = 0.028). Conclusions: Underweight and overweight history in the twenties are not simply mirror-image exposures but rather have sex-dependent and asymmetric associations with later HbA1c regulation.

Background: The first 1000 days of a child’s life, from a woman’s pregnancy to her child’s second birthday, represent a critical window during which nutritional and environmental exposures shape long-term health. Gut microbiota play an important role in metabolic and overall health. Although pet exposure during pregnancy affects neonatal microbiota, immunity, and development, its effects on maternal health remain unclear. This study investigated the associations of pet exposure with gestational health, maternal and infant microbiota, and breast milk composition in overweight/obese pregnant women. Methods: Fecal samples and breast milk samples were collected from pet-exposed participants (n = 22) and non-exposed controls (n = 32) for 16S rRNA sequencing. Breast milk lipids and proteins were also quantified. Results: Pet exposure before conception, during pregnancy, and postpartum was not associated with gestational diabetes mellitus or gestational weight gain. In the maternal gut, the relative abundances of Proteobacteria, Verrucomicrobia, Sutterellaceae, Enterobacteriaceae, Akkermansia muciniphila, and Parabacteroides were higher, whereas that of Ruminococcus was lower, in the pet-exposed group. In breast milk, the relative abundance of Escherichia-Shigella and the concentrations of phosphatidylinositol 36:2, phosphatidylethanolamine 38:3, lysine, and β-casein were higher, whereas the abundance of Rothia was lower, in the pet-exposed group. The relative abundance of Escherichia-Shigella was also lower in the infant gut of the pet-exposed group. Conclusions: In overweight/obese pregnant women, pet exposure was associated with differences in maternal gut and breast milk microbiota, higher concentrations of selected breast milk phospholipids and β-casein, and lower Escherichia-Shigella abundance in the infant gut.

Background: Neonatal birth weight is a key determinant of short- and long-term health outcomes. Pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) are important predictors of birth weight; however, their independent associations remain unclear, particularly in settings where national GWG guidelines are lacking. Methods: A prospective cohort study was conducted among 340 pregnant women in Ulaanbaatar, Mongolia in 2022. Data were collected using standardized questionnaires and anthropometric measurements. Pre-pregnancy BMI and GWG were classified according to World Health Organization criteria and the 2009 Institute of Medicine guidelines. Multivariable linear regression models were used to examine independent associations with neonatal birth weight. Results: The mean maternal age, pre-pregnancy BMI, and GWG were 30.3 ± 6.0 years, 23.5 ± 4.4 kg/m², and 14.3 ± 6.2 kg, respectively. Both BMI and GWG were independently associated with neonatal birth weight (p < 0.001), with no significant interaction observed (p = 0.147). Birth weight increased by 29.7 g (95% CI: 18.6–40.8) per 1 kg/m² increase in BMI and by 31.7 g (95% CI: 24.0–39.4) per 1 kg increase in GWG. Compared with normal BMI, overweight/obesity was associated with higher birth weight, while excessive GWG increased and inadequate GWG decreased birth weight (all p < 0.05). Conclusions: Pre-pregnancy BMI and GWG were independently associated with neonatal birth weight, with GWG showing a slightly stronger association. These findings highlight the importance of optimizing maternal weight before and during pregnancy. Countries undergoing rapid nutritional transitions may benefit from developing context-specific GWG guidelines, with Mongolia representing a relevant example. Full article

Background/Objectives: Preterm birth (PTB) is a major public health concern worldwide, which may lead to detrimental maternal and neonatal outcomes. Maternal nutritional status, gestational weight gain (GWG), and lifestyle factors are potentially modifiable determinants of adverse pregnancy outcomes. This study examined the association between PTB and maternal GWG and assessed whether maternal dietary habits and lifestyle factors were related to GWG in women delivering preterm versus at term. Methods: A retrospective case–control study was conducted at a tertiary center in Hungary (MANOR Study, 2019). The case group included n = 100 women with PTB, while n = 200 matched term deliveries served as controls (1:2 ratio). Data were collected using a self-administered questionnaire and medical records. Pre-pregnancy body mass index (BMI) was categorized using standard definitions, while GWG was classified as inadequate, recommended, or excessive according to the US 2009 Institute of Medicine guidelines. A 7-item dietary index score was calculated based on gestational dietary habits. Results: Pre-pregnancy BMI distribution did not considerably differ between groups (p > 0.05); over one-third of women in both groups were overweight or had obesity (38.7% vs. 36.7%). Previous PTB (p < 0.001) and gestational hypertension (GHT) (p = 0.003) were more common among current PTB cases, while smoking, alcohol consumption, and gestational diabetes mellitus (GDM) showed negligible differences (p > 0.05)—28.0% of cases, and 34.5% of controls were classified as having healthy dietary habits, based on the dietary index score calculated. Inadequate GWG was more prevalent among PTB cases (49.0% vs. 26.8%), whereas excessive GWG was less frequent among cases (21.9% vs. 38.4%). Being within the recommended GWG range and the manifestation of gestational hypertension were associated with lower (aOR: 0.39; 95% CI: 0.18–0.87; p = 0.020) and higher (aOR: 3.43; 95% CI: 1.44–8.19; p = 0.005) odds of PTB, respectively. Conclusions: Inadequate GWG was more common in PTB, while excessive GWG was more frequent in term pregnancies. Fast-food consumption was associated with excessive GWG among term births. Optimizing GWG and improving maternal diet quality should be included as key, cross-cutting interventions targeting the improvement of antenatal care. Full article

Background/Objectives: Obesity in young adults is a major public health concern and a key contributor to cardiometabolic risk. Vitamin K2 (VK2) has been proposed as a potential adjuvant therapy; however, evidence from randomized controlled trials remains limited. This study evaluated the effect of VK2 supplementation on cardiometabolic risk factors in young adults with overweight or obesity. Methods: In this 12-week randomized, double-blind, placebo-controlled trial (NCT05995522), men and women aged 18–35 years with overweight or obesity (BMI 25–40 kg/m²) were assigned to receive VK2 (menaquinone-4, 100 µg/day) or placebo. Both groups received standardized nutritional counseling. Body composition, blood pressure, glucose homeostasis, lipid profile, and vitamin K-dependent proteins were assessed at baseline and post-intervention. Between-group differences were analyzed using ANCOVA adjusted for baseline values. Results: Forty-six participants completed the study (placebo n = 24; VK2 n = 22). VK2 supplementation significantly reduced total cholesterol (−10.64 mg/dL, p = 0.038) and LDL cholesterol (−6.12 mg/dL, p = 0.005) compared with placebo. A reduction in systolic blood pressure showed a trend toward significance (−5.56 mm Hg, p = 0.067). No significant effects were observed on body composition, glucose metabolism, or vitamin K-dependent proteins. Conclusions: VK2 supplementation resulted in improvements in total and LDL cholesterol levels, with no significant changes in vitamin K-dependent proteins, and may represent a safe and potentially beneficial adjunct to nutritional strategies aimed at early cardiometabolic risk modulation.

Background: The relationship between AMH (anti-Müllerian hormone) levels, fat distribution, and insulin resistance in women with PCOS has been widely studied, yet findings remain inconsistent. Recent guidelines emphasize the growing role of AMH in PCOS diagnosis and suggest its potential inclusion among diagnostic criteria, highlighting its relevance for guiding therapeutic management. Objectives: This retrospective study aimed to evaluate the association between AMH levels and metabolic parameters in overweight and obese reproductive-age women with PCOS. Ethical approval was obtained from the bioethics committee. Methods: Two groups of 52 women each were selected from PCOS patients treated at our clinic between 2024 and 2025: one with a waist-to-hip ratio (WHR) ≤ 0.85 and the other with a WHR > 0.85. Venous blood samples were collected to measure AMH, fasting glucose, and fasting insulin. Body height and weight were recorded to calculate body mass index (BMI), and insulin resistance was assessed using HOMA-IR. Waist and hip circumferences were measured to determine WHR. Results: The association between central adiposity and AMH in overweight and obese women with PCOS depended on insulin resistance. In insulin-resistant women, higher WHR was linked to lower AMH, whereas in women without insulin resistance, higher WHR corresponded to higher AMH levels. Conclusions: Insulin resistance appears to influence AMH in opposite directions depending on a woman’s WHR, suggesting its potential role in tailoring individualized treatment strategies.

Background: Overweight and obesity remain major public health challenges in Puerto Rico, affecting over 70% of adults and contributing to cardiovascular, metabolic, and mental health disorders. This study explores the psychosocial and behavioral factors influencing obesity within low-income Puerto Rican communities, emphasizing both biological sex differences and socially defined sex-role influences, along with their respective mental health dimensions. Method: Using a qualitative approach, Community-Based Participatory Research (CBPR), ten focus groups were conducted with 71 participants (37 women and 34 men) from two municipalities in southern Puerto Rico. Discussions were analyzed thematically with the Socioecological and Health Belief Models to identify key determinants. Results: The data collected revealed that women expressed greater emotional vulnerability, frequently citing anxiety, depression, body image concerns, and stress-related eating as contributors to obesity. Men, meanwhile, reported frustration with diet adherence, economic limitations, and healthcare inaccessibility. Across participants, economic hardship, cultural norms, and limited health education emerged as major obstacles. Conclusions: Findings underscore the need for holistic, sex-informed and socially responsive interventions that integrate mental health support with nutritional and physical health strategies. Addressing self-esteem, emotional regulation, and stress management alongside behavioral modification can promote sustainable, culturally tailored obesity prevention in Puerto Rico. Full article

Background: Obesity represents a major public health challenge worldwide and contributes substantially to the burden of type 2 diabetes and hypertension. While body mass index (BMI) is widely used in clinical practice, indices reflecting central adiposity may provide additional prognostic value. This study aimed to assess the prevalence of general and central obesity in an adult population across different age groups from Stara Zagora, Bulgaria, and to examine their associations with cardiometabolic outcomes and lifestyle factors. Methods: A quasi-representative cross-sectional study was conducted among 3512 adults (mean age 53.7 ± 14.9 years). Anthropometric indices, including BMI, waist circumference, waist-to-hip ratio, and waist-to-height ratio were measured. Cardiometabolic outcomes included diabetes, hypertension, and their combined presence. Multicollinearity was assessed using the Variance Inflation Factor (VIF), and the discriminatory ability of indices was evaluated using Receiver Operating Characteristic (ROC) analysis and DeLong’s test. Results: The prevalence of overweight/obesity (BMI ≥25) was 68.4%, while central obesity (WHtR ≥0.5) affected 66.9% of participants. BMI demonstrated the highest discriminatory ability in this dataset for hypertension (AUC = 0.852) and diabetes (AUC = 0.796), significantly outperforming WC and WHR (p < 0.05). However, 24.4% of individuals with normal BMI exhibited high-risk central adiposity. Significant sex-specific differences were observed: short sleep duration (<6 h) was a strong predictor of obesity in women (aOR = 2.98), whereas smoking showed stronger associations in men. Age-stratified analyses revealed that while BMI stabilizes in the oldest age group (75–89 years), WHtR continues to increase, reflecting age-related redistribution of visceral fat. A strong protective effect of physical activity was observed, supported by quasi-complete separation in active subgroups. Conclusions: General and central obesity represent a substantial health burden in this urban population. While BMI remains a robust screening tool, the integration of WHtR enhances the identification of “hidden” cardiometabolic risk particularly in older adults and individuals with normal BMI. Given the quasi-representative nature of the sample, these findings are primarily generalizable to similar urban populations and may inform targeted regional public health strategies. Full article

Low glycemic-index foods may reduce postprandial oxidative stress by reducing postprandial glucose excursions, but the evidence for this is limited by dietary confounders. To determine whether reducing postprandial glucose per se reduces postprandial oxidative stress, overnight-fasted participants (BMI 25.0–39.9 kg/m², n = 18) consumed four test meals in random order: 75 g dextrose solution (Dex) within 5 min (bolus/noC), Dex slowly over 3.25 h (sipping/noC), bolus with 1 g vitamin C (bolus/C) and sipping with 1 g vitamin C (sipping/C). Venous blood was taken at intervals over 6 h; a standard lunch was consumed at 4 h. Sipping flattened postprandial glucose and insulin and reduced free fatty acid rebound compared to bolus (p < 0.05). Vitamin C raised serum vitamin C from ~20 to ~55 μmol/L. The total peroxyl radical trapping antioxidant potential (TRAP) increments differed after lunch, with a main effect of vitamin C at 5 h (mean ± SEM; C 70 ± 23 vs. noC −29 ± 27; p = 0.016) and main effects of rate (sipping 57 ± 25 vs. bolus −71 ± 28; p = 0.0002) and vitamin C (C 58 ± 25 vs. noC −73 ± 28; p = 0.0003) at 6 h. By multiple regression analysis, the TRAP area under the curve (AUC) was positively associated with the insulin AUC (p < 0.001) and negatively with the glucose and vitamin C AUCs (p < 0.05). The oxidized LDL increments were higher 6 h after sipping than bolus (7 ± 7 vs. −20 ± 7, p = 0.005). The oxidized LDL AUC was negatively associated with the TRAP AUC (p < 0.001). These results support the hypothesis that reducing postprandial glucose reduces postprandial oxidative stress. Full article
