34, 95% confidence interval (CI) 0.14-0.83] and tolerance (OR 0.35, 95% CI 0.16-0.81) of food; and laparoscopic/laparoscopic assisted (vs. open/converted to open surgery) was associated with early tolerance of food (OR 1.99, 95% CI 1.17-3.39). CONCLUSIONS While three-quarters of the study population ate solid food early, only one-third tolerated solid food early. Findings suggest that bowel preparation and surgery type are factors warranting further investigation in future studies to improve uptake of early post-operative feeding. BACKGROUND & AIMS Oxidative stress has been suggested to play an important role in the pathophysiology of depression, and a diet high in antioxidants may improve mood. However, studies addressing this issue are scarce. The aim of this cohort study was to investigate the prospective association between dietary non-enzymatic antioxidant capacity (NEAC) in overall diet and depressive symptoms in Japanese employees. Additionally, we examined the association separated by dietary NEAC sources. METHOD Participants were 911 workers without depressive symptoms at baseline and participated in 3-y follow-up survey. Dietary NEAC was determined from a database of NEAC measurements obtained by ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC). Dietary NEAC was calculated by multiplying the estimated NEAC values with the consumed amount and summing up those values. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Logistic regression was used to estimate odds ratios of depressive symptoms according to overall NEAC and separately from foods and beverages. RESULTS At 3-y follow-up, 153 (16.8%) workers were newly identified as having depressive symptom. No significant associations were found between higher level of overall dietary NEAC and decreased risk of depressive symptoms after adjustment for potential confounders (overall FRAP, P for trend = 0.19 and ORAC, P for trend = 0.20). Likewise, neither higher dietary NEAC from foods nor beverages were related with lower depressive symptoms. CONCLUSION Our findings did not support an inverse association between dietary NEAC and the risk of depressive symptoms in Japanese workers. BACKGROUND & AIMS Patients with celiac disease (CD) often report inadvertent gluten exposures and challenges reading labels. The most common cause of non-responsive CD is gluten exposure. We aimed to assess whether recently diagnosed CD patients can determine whether a food is gluten-free based on labeling, and to assess skills over time. A secondary aim was to identify factors associated with label reading proficiency. METHODS Inception cohort with follow-up at 6, 12, and 24 months after diagnosis. Participants were asked to determine whether 25 food items were gluten-free based on labeling information. Diet adherence was assessed using the Celiac Diet Assessment Tool (CDAT) and the Gluten-Free Eating Assessment Tool (GF-EAT). 144 adults with newly diagnosed celiac disease were enrolled. The initial quiz at 6 months was completed by 83%. Quizzes were completed by 72% at 12 months and 70% at 24 months. RESULTS Median overall accuracy scores were 23/25, 24/25 and 21/25 at 6, 12 and 24 months respectively. Gluten-free products with explicit "gluten-free" claims had the fewest errors. Quiz scores were not correlated with tTG IgA levels, or CDAT or GF-EAT scores. Diet adherence was generally good (>85% with CDAT less then 13 suggesting adequate GFD adherence); however, at 24 months, only 11% reported no gluten exposure. CONCLUSIONS CD patients may be unable to consistently choose gluten-free foods based on product labeling. Explicit identification of gluten-free products may be helpful. Label reading ability appears stable over time. Further studies are needed to evaluate whether erroneous label reading or misleading labels are associated with persistent villous atrophy. BACKGROUND This study was designed to determine the effects of two dosages of vitamin D supplementation on inflammatory biomarkers in patients with ulcerative colitis (UC). Metabolism inhibitor METHODS Fifty mild to moderate active UC patients were randomly assigned to consume either 2000 or 1000 IU/day vitamin D for 12 weeks. Inflammatory biomarkers, disease activity, quality of life, anthropometric indices, dietary intakes, and physical activity were measured at the beginning and the end of the study. RESULTS Serum level of hs-CRP decreased in both groups at the end of study, but the changes were not significantly different within and between groups. Serum level of TNF-α in the high dose group was reduced at the end of the study non-significantly (P-value = 0.289). In the low dose group, a significant increase in serum TNF-α concentration was observed (p ≤ 0.001). The changes in serum TNF-α were significantly different between two groups (p = 0.005); however, after adjusting for the effect of confounders, the significance effect was disappeared (p = 0.162). Activity of NF-κB increased in both groups while this increase was significant in the low dose group compared to the baseline (p ≤ 0.001), and to high dose group (p = 0.006). After adjustment for confounders, the difference between groups remained statistically significant (p = 0.002). CONCLUSION Our results indicate that 12 weeks supplementation with 2000 IU/day vitamin D prevents from systematic inflammation, while decreasing disease activity in patients with mild to moderate active UC. Further studies are needed to find the optimum dosage and duration of supplementation. This Trial was registered at IRCT.ir with number of IRCT 20100524004010N22. BACKGROUND & AIMS The DASH diet (Dietary Approaches to Stop Hypertension) is considered a healthy dietary pattern, and is recommended for the control of arterial hypertension (AH). However, its role in the adolescent population needs to be better investigated and clarified. The aim of this study is to identify the association between AH and the DASH diet score in a representative sample of Brazilian adolescents. METHODS A cross-sectional study using data from a national, multicenter and schoolbased probabilistic sample of 71,553 Brazilian adolescents who had their blood pressure (BP) measured and completed a 24-hour dietary recall (2013-2014). The components of the DASH score were assessed. Logistic regression models were used to evaluate the association between AH, anthropometric and sociodemographic variables, and the tertile of the DASH score. RESULTS Approximately 11% of the adolescents who were in the 3rd tertile of the DASH score presented AH, 18% were overweight and 9% were obese. Among the components of the score, the highest intake was sugar-sweetened beverages (92.
