Background/Objectives: To examine the associations of dietary inflammatory index (DII) with bone mineral density (BMD) and fracture risk in adult Americans. Subjects/Method: The United States National Health and Nutrition Examination Survey participants during 2005-2010 were included if they had measured data on dietary intake and BMD. DII scores were calculated from estimated micro- and macronutrients from a single 24-h dietary recall. BMD was measured using dual-energy X-ray absorptiometry densitometers. Risk of fractures was obtained from participant self-report (ever) based on doctor information. Analyze of covariance and [chi].sup.2-tests were employed, while accounting for the complex survey design. Results: A total of 18 318 participants were included, with 51.3% (9397) being men. Age, sex, race, physical activity, smoking, C-reactive protein and body mass index-adjusted mean BMD (g/cm.sup.2) in different bodily sites significantly decreased across increasing quarters of the DII (all P Conclusions: The current study provides evidence suggesting a potential adverse effect of pro-inflammatory diet on bone health; which may have implications for dietary approaches for those with history of abnormal bone health complications., Author(s): M Mazidi [sup.1] [sup.2] , N Shivappa [sup.3] [sup.4] [sup.5] , M D Wirth [sup.3] [sup.4] [sup.5] , J R Hebert [sup.3] [sup.4] [sup.5] , H Vatanparast [sup.6] , [...]

BACKGROUND/OBJECTIVES: Obese infants are more susceptible to develop adulthood obesity and its related comorbidities. Previous studies have shown the presence of hormones and growth factors in maternal breast milk that may influence infant adiposity. The aim of this study was to investigate differences in concentrations of three hormones and two growth factors in the breast milk of mothers with obese and non-obese infants. SUBJECTS/METHODS: In this cross-sectional study, 40 mothers with overweight or obese infants (weight for length percentile >97) and 40 age-matched mothers with normal-weight infant (-10 < weight for length percentile < 85) who were between 2 and 5 months of age were enrolled. Anthropometric indices of infants and mothers were measured by routine methods. Breast milk concentrations of ghrelin and adiponectin, leptin, epithelial growth factor (EGF) and insulin-like growth factor-1 (IGF-1) were measured using enzyme-linked immunosorbent assay methods. RESULTS: The mean breast milk concentration of ghrelin was higher in mothers with normal-weight infants, 137.50 pg/ml, than in mothers with obese infants, 132.00 pg/ml (P =0.001). This was also true regarding the concentration of EGF in mothers with (0/04 ng/ml) and without (0/038 ng/ml) normal-weight infants (P = 0.01). No significant differences were observed in concentrations of leptin, adiponectin and IGF-1 between two groups (P>0.05). There was also a significant positive correlation between EGF and ghrelin in both groups. CONCLUSIONS: This study revealed that there was a correlation between ghrelin and EGF level in breast milk of mothers with obese and non-obese infants, suggesting a possible regulatory effect of these two hormones on weight in infants. European Journal of Clinical Nutrition (2015) 69, 614-618; doi: 10.1038/ejcn.2014.205; published online 5 November 2014, INTRODUCTION Obesity and its comorbidities have been increasing in prevalence, including in children and infants.

Dietary nitrates are thought to confer several cardiometabolic health benefits, including improvements in blood pressure and the plasma lipid profile. However, existing data from Iran is conflicting and there is a dearth of literature focusing on non-adult populations. A total of 988 adolescent girls were recruited from schools in different areas of Mashhad and Sabzevar, Iran. Dietary nitrate intake was assessed using a food frequency questionnaire and participants were categorized into quartiles based on this. Differences in participant characteristics between quartiles were assessed using one-way ANOVA and associations between total nitrate intake, nitrate intake from vegetables and cardiometabolic risk markers (blood lipid profile, fasting blood glucose, systolic and diastolic blood pressure) were assessed using linear regression. Nitrate intake from vegetables was positively correlated with triglycerides, even after adjusting for several variables (β = 0.086, 95% CI = 0.002-0.097; P = 0.043). Total nitrate intake was also significantly positively associated with serum triglycerides (β = 0.097, 95% CI = 0.010-0.084; P = 0.012); however, this relationship disappeared after adjusting for several variables. Significant interaction effects were observed between total nitrate intake, nitrate intake from vegetables, and vitamin C upon triglycerides (P < 0.01). No significant relationships were found between total nitrate intake, nitrate intake from vegetables, and other cardiometabolic risk markers. Our findings suggest there may be neutral or possibly detrimental cardiovascular effects of dietary nitrate and/or vitamin C intake which are not in agreement with contemporary literature and warrant further investigation., (© 2024.

The prevalence of non-alcoholic fatty liver disease (NAFLD) is rising-caused, at least in part, by unhealthy lifestyles including poor dietary choices. We examined the link between the inflammatory potential of diet as measured by the Dietary Inflammatory Index (DII ® ) and liver function tests [summarised by the fatty liver index (FLI)]. Of 20,643 US NHANES participants, 48.7% were men and the mean age was 47.3 years. Significant associations were apparent between increasing DII score and prevalent fatty liver. Individuals in the fourth DII quartile had nearly a six-fold higher likelihood of fatty liver [odds ratio (OR) = 5.97, 95% confidence interval: 4.44-8.02] compared with those in the first quartile. Moderation analysis indicated a significant impact of adiposity on the link between FLI and DII score (p < 0.001). This study provides further evidence of an association between the inflammatory potential of diet and fatty liver.

Objectives: Metabolic syndrome (MetS) represents a clustering of metabolic abnormalities that are associated with an increased risk of type 2 diabetes and cardiovascular disease. We aimed to evaluate the effects of sesame oil enriched with vitamin E (vit E), sesame oil alone and sunflower oil on lipid profile, fasting blood glucose (FBG), malondialdehyde (MDA), high-sensitivity C-reactive protein (Hs-CRP), homeostatic model assessment (HOMA-IR), and blood pressure (BP) in patients with MetS., Subjects: Overall, 75 individuals with MetS (aged 30-70 years) participated in this randomized, single-blind controlled trial. Patients were randomly allocated to: (1) Group A (n = 25): sesame oil (30 ml/day) enriched with vit E (400 mg/day), (2) Group B (n = 25): sesame oil (30 ml/day), (3) Group C (n = 25): sunflower oil (30 ml/day). Anthropometric data, dietary intake, blood pressure, and biochemical markers, including fasting serum lipids, FBG, serum insulin, MDA, and hs-CRP were measured at baseline and at week 8., Results: In individuals in the sesame oil enriched with vit E group (Group A), there were significant reductions in serum total cholesterol (TC), triglycerides (TG), FBG, HOMA-IR, MDA, hs-CRP, high-density lipoprotein (HDL-C) systolic and diastolic BP (for all the comparison p < 0.02). Similarly, in Group B (taking sesame oil alone), TC, TG, FBG, HOMA-IR, MDA, systolic and diastolic BP were significantly improved (for all the comparison p < 0.025), while there were no significant changes in serum HDL (baseline = 35.9 ± 7.2 mg/dL vs. 36.4 ± 6.2 mg/dL, p = 0.432) and hs-CRP (baseline = 4.38 ± 1.34 mg/dL vs. week 8 = 3.96 ± 1.7 mg/dL, p = 0.057) in second group. No significant changes in any of the studied clinical and anthropometric data were found in Group C (on sunflower oil)., Conclusion: Sesame oil (±vit E) was shown to beneficially affect several cardiometabolic indices (including lipids, FBG, BP, HOMA-IR, and MDA) in patients with MetS.

We aimed to evaluate the association between serum lipophilic antioxidants and liver function and prevalent non-alcoholic fatty liver disease (NAFLD). The Nutrition and Health Examination Surveys data were used (randomly selected population, 2001 and 2006). A total of 9658 participants were included, of whom 44.6% had prevalent NAFLD. In adjusted logistic regression models, participants in the top quarter of vitamin A and E had 56% (95% confidence interval (95%CI): 45-68) and 34% (95%CI: 29-57) lower odds of NAFLD compared with participants in the bottom quarter. When levels of vitamin A changed from low (1.53) to high (1.95), the fatty liver index (FLI) in the low body mass index (BMI) category changed from 36.1 to 24.3. However, at the high BMI level, FLI changed from 84.3 to 65.1 suggesting that obesity modulates the effects of vitamin A on FLI. This study suggests a protective effect of antioxidants against NAFLD occurrence, which is likely modulated by adiposity. Given the cross-sectional design, our results need to be validated in prospective studies.

Background/objectives: To assess the relationship between plasma trans-fatty acids (TFAs) levels and leucocyte telomere length (TL) in a US adult population sample., Subjects/methods: National Health and Nutrition Examination Survey (NHANES) database was used for this study. Gas chromatography was used to separate derivatised fatty acids (Four major TFAs [palmitelaidic acid (C16:1n-7t), trans vaccenic acid (C18:1n-7t), elaidic acid (C18:1n-9t), and linoelaidic acid (C18:2n-6t,9t)]) which were then quatified using negative chemical ionization mass spectrometry. Data analyses used multivariable linear regressions, while accounting for the survey design., Results: A total of 5446 eligible participants, with 46.8% (n = 2550) being men, were included. Their average age was 47.1 years for the total sample, and 47.8 and 46.5 years in men and women respectively (p = 0.085 for men vs. women difference). Concentrations of palmitelaidic acid and linolelaidic acid decreased with increasing length of the telomere (p < 0.05). Univariable linear regressions revealed a significant negative association between levels of the palmitelaidic acid, elaidic acid, vaccenic acid, and linolelaidic acid with TL. However when models were adjusted for age, sex, ethnicity, education, marital status, sub-clinical inflammation, body mass index, and smoking, only palmitelaidic acid and linolelaidic acid remained significant (p < 0.05)., Conclusions: TFAs levels and particularly palmitelaidic and linolelaidic acids, are likely negatively associated with telomere lenght. Future studies should explore the potential implications of these associations.
