The negative relationship between carbohydrate intake with lipid profiles and body weight has been previously investigated. However, this is the first study seeking to assess the association of carbohydrate quality index (CQI) with CVD risk factors.MethodsThis cross-sectional study was conducted on 291 Iranian overweight and obese women, with a body mass index (BMI) ranging between 25 and 40 kg/m2, and aged 18–48 years. CQI scores were calculated by using a validated 168-item semi-quantitative food frequency questionnaire (FFQ). Biochemical and anthropometric measures were assessed using standard methods, and bioelectrical impedance was used to measure body composition.ResultsWe observed that fruits (P < 0.001), vegetables (P < 0.001), and protein (P = 0.002) intake were higher in participants with a higher score of the CQI. When we adjusted for potential confounders, we observed that th...

Methods A comprehensive search was done in PubMed, Scopus, Web of Science, Embase, and Cochrane databases up to December 2020. We used standard and weighted mean differences and 95% confidence intervals for net changes in selected parameters of immune responses. Subgroup analysis was used to find heterogeneity. Result Overall, 35 RCTs comprising 1995 participants were eligible for this meta-analysis. There was a significant reduction of circulating CRP (WMD: −32.4; 95% CI: −44.45 to −19.62, p < 0.001), hs-CRP (WMD: −0.95; 95% CI: −1.01 to −0.89, p < 0.001), Neutrophil levels (SMD: −0.46; 95% CI: −0.90 to −0.01, p = 0.043), following zinc supplementation. CD4 level also increased significantly, (WMD: 1.79; 95% CI: 0.57 to 3, p = 0.004). Zinc supplementation had no significant effect on WBC (SMD: −0.66; 95% CI: −1.67 to 0.36, p = 0.204), lymphocyte (WMD: 1.86; 95% CI: −0.86 to 4.58, p = 0.181), monocyte levels (SMD: −0.16; 95% CI: −0.07 to 0.39, p = 0.167), CD3 (SMD: 0.37; 95% CI: −0.49 to 1.22, p = 0.399). Conclusion Zinc supplementation decreased the CRP, hs-CRP and TNF-α, IL-6, neutrophil and increased CD3 and CD4 level significantly.

Methods: This cross-sectional study was conducted among 371 healthy 18 to 50 year-old Iranian women. Participant dietary intake was assessed using a validated food frequency questionnaire. Nineteen food groups were ranked in deciles and received scores from 1 to 10. An overall plant-based dietary index (PDI), a healthy plant-based dietary index (hPDI), and an unhealthy plant-based dietary index (uPDI) were calculated. Results: Participants who scored in the top tertile of the PDI or uPDI consumed less fat and protein and more carbohydrates, compared to women in the lowest tertile (P < 0.05). There was no significant variation in macronutrient consumption between the highest and lowest tertiles of hPDI. Participants who scored in the highest tertile of...

This study aimed to summarize the current literature to determine whether almonds can affect inflammatory markers. A systematic search was carried out in PubMed, Scopus, and ISI Web of Science up to March 2021. Randomized clinical trials that compared almond with no almond consumption were included. The outcomes of interest were changes in circulating C-reactive protein (CRP), IL-6, TNF-α, intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) concentrations. The random-effects model was used to find the mean differences. In total, 18 trials with 847 participants were eligible for the current analysis. Participants’ ages ranged from 26.3 to 69.6 y. Combining 16 studies, almond consumption significantly reduced serum concentrations of CRP [weighted mean difference (WMD): −0.25 mg/L; 95% CI: −0.43, −0.06 mg/L; I2 = 0.0%; P-heterogeneity = 0.6...

Thus, whey protein that contains higher amounts of EAA can have a considerable effect on modifying muscle synthesis. However, there is insufficient evidence regarding the effect of soya and whey protein supplementation on body composition. Thus, we sought to perform a meta-analysis of published randomised clinical trials that examined the effect of whey protein supplementation and soya protein supplementation on body composition (lean body mass, fat mass, body mass and body fat percentage) in adults. We searched PubMed, Scopus and Google Scholar, up to August 2020, for all relevant published articles assessing soya protein supplementation and whey protein supplementation on body composition parameters. We included all randomised clinical trials that investigated the effect of whey protein supplementation and soya protein supplementation on body composition in adults.

Methods: This analytic cross-sectional study included 400 pregnant women. The nutritional, demographic, clinical data, and fasting blood samples (selected micronutrients and blood glucose) were evaluated. The data were analyzed using chi-square, independent t-test, and logistic regression tests. Results: The prevalence of gestational diabetes mellitus (GDM) was 18%. The OR for GDM was (OR: 0.329; 95% CI: 0.156-0.696) in normal-weight compared to mothers who were obese before pregnancy. Normal serum zinc concentration was associated with 0.413-fold lower rates of developing GDM (95% CI: 0.227-0.750). Magnesium supplementation was inversely associated with the risk of GDM (OR: 0.986; 95% CI: 0.979-0.994). Inadequate and exces...

Thus, understanding the influence of overall quality of diet and dietary patterns on anthropometric measures during childhood is critical to inform dietary recommendations. The current study used an updated version of the healthy eating index (HEI) to evaluate the association between overall diet quality and measures of childhood development in six-year-old children. METHODS This cross-sectional study was conducted across 788 six-year-old children referred to healthcare centers in Tehran, Iran. Anthropometric indices and dietary intake were evaluated using standard protocols and food frequency questionnaires, respectively. The HEI-2015 was used to evaluate participant diet quality. The total HEI-2015 score ranged from zero to 100 using the sum of thirteen food score components. RESULTS Children in the highest tertile of HEI score had higher nutrient intakes and HEI-related food groups (p < 0.05). Children within the highest tertile of HEI score compared to those within the lowest tertile were more likely to be overweight (OR: 1.45; 95% CI = 1.01; 2.08). CONCLUSIONS Findings presented in this study showed that HEI was not associated with a greater likelihood of obesity, underweight, severe underweight, and stunting. However, children in the highest tertile of HEI score were more likely to be overweight.

Low resting metabolic rate (RMR) caused by the diet has been shown to have, potentially, unfavorable effects on obesity. This study sought to investigate the interactions between the Cry 1 Gene and fat intake on RMR in women with overweight of obesity. Methods This comparative cross-sectional study was conducted on 377 Iranian women with overweight of obesity. A food frequency questionnaire (FFQ), with 147 items, was used to assess dietary intake. Individuals were categorized into two groups based on the rs2287161 genotype. Body composition, dietary intake, and RMR were assessed for all participants. Results There was a significant difference between genotypes for fasting blood sugar (FBS) (P = 0.04), fat free mass (FFM) (P = 0.0009), RMR per FFM (P = 0.05), RMR per body mass index (BMI) (P = 0.02), and RMR deviation (P...
