Oil consumption is an important part of the modifiable nutritional risk factor of cardiovascular diseases. The present study aims to examine the effects of grape seed oil consumption against sunflower oil on lipid profiles, high-sensitivity C-reactive protein, and weight management among overweight and obese females. In the current randomized clinical trial, 39 overweight or obese women were randomly allocated into the grape seed oil and sunflower oil groups and completed the study successfully. Anthropometric parameters were measured every two weeks. Fasting serum lipid profiles and high-sensitivity C-reactive protein levels were measured at the beginning and at the end of the intervention. Dietary data were collected using 3 days of 24-hours dietary recall. The changes in anthropometric measures and nutrient intakes at the end of the study were not significant between the groups. Although lipid profiles improved significantly in both groups, only the changes of the low-density lipoprotein (25.9 ± 6.6 mg/dL vs. 8.63 ± 6.87 mg/dL) and high-density lipoprotein (5.35 ± 2.56 mg/dL vs. 1.73 ± 1.14 mg/dL) were significantly different between the grape seed oil and sunflower oil groups. The changes in the high-sensitivity C-reactive protein level in the grape seed oil vs. sunflower oil group were statistically significant (P = 0.03). Grape seed oil consumption seems to improve lipid biomarkers and reduce the risk of cardiovascular diseases in overweight and/or obese females.

This study aims to systematically examine the effects of community-based interventions on fruits and vegetables consumption in adults. Design/methodology/approach To collect relevant publications, the authors searched electronic databases including PubMed/MEDLINE, Scopus and Web of Science from January 2000 to July 2021. Considering random models, this study analyzed the data using weighted mean differences (WMD) and 95% confidence intervals (CI). Findings Among 1,621 retrieved publications, 21 articles met the inclusion criteria. The overall effect size demonstrated that, at the end of the trials, the educational interventions increased the consumption of aggregated fruits and vegetables (WMD: 0.55 serving/day, 95%CI: 0.34, 0.77), and vegetables (WMD: 0.15, 95%CI: 0.09, 0.21, I2: 33.2%; p = 0.103) in the intervention groups, compared to the ...

The prevalence of childhood obesity has increased worldwide and various environmental factors have accelerated this trend. Several reports have suggested that food advertising causes childhood obesity. We proposed a review study to evaluate the relationship between TV food advertisements and obesity in children. By searching over electronic databases (including PubMed, Web of Science, Scopus, and Google Scholar), the reference lists of original studies, and reviews using key search terms, 1181 articles were identified. Out of these, only 9 articles met the inclusion and quality criteria. Most of the longitudinal study carried out at the national level have reported a significant association between commercial viewing and BMI in children. The duration of these studies varied between 7 months and 5 years. The children’s TV viewing time was between 1.5 and 3.5 hours per day. Results of the reviewed studies have revealed a controversial attitude about the influence of TV food advertisements on obesity. However, three of four modeling studies indicated an increment in the prevalence of overweight and obesity following exposure to food advertisements. Further interventional and longitude studies are needed to achieve more precise results.

Patients were randomized in a 1:1:1:1 allocation ratio to 1of 4 treatment groups: (A) 5 mg of boron citrate twice a day, (B) 200 mg of oleoylethanolamide twice a day, (C) both therapies, or (D) routine treatments without any study medications. At pre-and post-intervention phase, some clinical and biochemical parameters were assessed.ResultsSupplementation with boron citrate alone or in combination with oleoylethanolamide significantly improved O2 saturation and respiratory rate (p < 0.01). At the end of the study, significant increases in white blood cell and lymphocyte count were observed in the boron citrate and combined groups (p < 0.001). Boron citrate supplementation led to a significant decrease in serum lactate dehydrogenase (p = 0.026) and erythrocyte sedimentation rate (p = 0.014), compared with other groups. Furthermore, boron citrate in combination with oleoylethanolamide resulted in a significant reduction in the high-sensitivity C-reactive protein and interleukin-1β concentrations (p = 0.031 and p = 0.027, respectively). No significant differences were found among four groups post-intervention, in terms of hemoglobin concentrations, platelet count, and serum interleukin-6 levels. At the end of the study, common symptoms of COVID-19 including cough, fatigue, shortness of breath, and myalgia significantly improved in the supplemented groups, compared to the placebo (p < 0.05).ConclusionSupplementation with boron citrate alone or in combination with oleoylethanolamide could improve some clinical and biochemical parameters in COVID-19 patients.

Studies on the impact of shrinking hyper-saline lakes suggest severe negative consequences for the health of the affected population. The primary aim was to investigate the relationship between changes in the water level of the hyper-saline Lake Urmia, along with the associated salt release, and the prevalence of hypertension and the general state of health of the local population in Shabestar County north of the lake. Moreover, we sought to map the vulnerability of the local population to the health risks associated with salt-dust scatter using multiple environmental and demographic characteristics. We applied a spatiotemporal analysis of the environmental parameters of Lake Urmia and the health of the local population. We analyzed health survey data from local health care centers and a national STEPS study in Shabestar County, Iran. We used a time-series of remote sensing images t...

Background: The Human Immunodeficiency Virus (HIV) epidemic is still a public health concern. Micronutrient deficiencies can fasten the progression of this syndrome. Selenium and zinc are essential trace elements, which exert antioxidant and anti-inflammatory activities in HIV infection. The present overview aimed to evaluate the current knowledge from systematic reviews (SRs) of the effects of selenium and zinc supplementation in HIV patients to show the most updated and comprehensive summary of previous SRs. Methods: The current study was performed according to the guidelines of the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) statements. To assess the quality of articles we used the Measurement Tool to Checklist Assess Systematic Reviews (AMSTAR). PubMed/Medline, Web of Science, Scopus, and EMBASE databases and Google Scholar web search engine were searched up until March 2022, using relevant keywords. Results: Among 3731 articles assessed, five and four studies met the inclusion criteria for selenium and zinc supplementation, respectively. Four studies found that selenium supplementation can be effective in delaying CD4 decline in HIV-infected patients. In four SRs, the dosage of selenium supplementation was 200 μg/day. Three studies, however, reported no significant effect of zinc supplementation on CD4 cell counts, and HIV viral load. The dosage of zinc supplementation ranged from 12 to 100 mg/day. The intervention duration ranged from 2 weeks to 18 months. Conclusion: In the present study, we identified some clinical evidence of a potential beneficial effect of selenium supplementation in HIV-infected patients.

Background: Previous studies have shown that some dietary components may be implicated in the aetiology of postmenopausal osteoporosis. Objective: We examined the relationship between Dietary Inflammatory Index (DII®) and osteoporosis in postmenopausal women. Study design: Eight hundred and fifty postmenopausal women aged 50–65 years were randomly selected from 87 health care centers. Bone mineral density (BMD) was measured using the anterior-posterior lumbar spine (L1-L4) and proximal femur neck through Hologic QDR 4500W (S/N 50266) dual-energy X-ray absorptiometry device. After checking inclusion and exclusion criteria and diagnosis of osteoporosis, 124 women with normal bone mineral density (normal-BMD) and 108 women with osteoporosis were selected. Demographic, anthropometric, physical activity, midwifery, and dietary intake questionnaires were completed. DII was calculated based on a valid and reliable 168-item semi-quantitative food frequency questionnaire using 37 (out of 45) food parameters. A Logistic regression model adjusted for confounders was applied to estimate osteoporosis’s odds ratio (OR) based on modeling DII as a continuous and dichotomous variable. Results: In this study, DII scores ranged from −3.71 (the most anti-inflammatory score) to +4.16 (the most pro-inflammatory score). The median DII value among the osteoporosis group was 0.97, among the normal group it was −0.31, indicating a more pro-inflammatory diet for osteoporosis. There were positive associations between osteoporosis and DII based on both continuous (Adjusted OR=3.467, 95% confidence interval (CI): 2.280–5.272, P-value&lt;0.001) and dichotomous (Adjusted OR: DII ≤−0.31 / &gt;−0.31=0.248, 95% CI: 0.110–0.561, P-value=0.001) measures in modeling adjusted for age, BMI, post-menopausal years, parity, education, total energy intake, and physical activity. Conclusions: These data suggest a pro-inflammatory diet, as indicated by increasing the DII score, may be a risk factor for osteoporosis in postmenopausal Iranian women.

However, evidence on the effectiveness of the TLL system on consumers’ choices is conflicting. The present study aims to systematically summarize the effects of TLL on consumers’ point of purchase behaviors. Methods: Five electronic databases, including PubMed/Medline, Scopus, Web of knowledge, the Cochrane library, and Science direct were searched from 2000/01/01 to 2021/11/01. Randomized-controlled trials, in English or Farsi languages, investigating the effects of TLL on choosing healthier foodstuffs or beverages were examined for eligibility and included in the review. Of 6408 potentially relevant publications (including 1255 duplicates), five clinical trials were finally included in the study. Results: The duration of the interventions ranged from 4 to 12 weeks and all studies except on...

This review study aimed to present the available policy options for increasing fruit and vegetable consumption in the populations. Methods: To collect relevant English publications, five electronic databases, including PubMed/Medline, Scopus, Embase, ProQuest, and Ovid from 2000 until 1st January 2021 were searched. The national or population based programs aimed to increase fruit and/or vegetable intake were included. Four types of policy options were recognized, including food promotion, school and workplace food environment regulations, agriculture, food production, supply and storage, and fiscal policies. Results: Increasing consumer’s knowledge has been more effective in increasing fruit and vegetable consumption among populations. However, most of the interventions in the workplace and school emphasize increasing knowledge and changing ac...

Boron is a potential essential trace element and there are some promising results on its weight lowering effect. Therefore, the present meta-analysis was aimed to assess the effect of boron on body weight. METHOD Databases including PubMed, Scopus, Cochrane Library, Embase, and Google Scholar were searched from 1995 until November 2021 using the definitive keywords. Searching was limited to articles with English language. Human studies were excluded in our analyses regarding their limited number and the heterogeneity of study designs. All of the relevant animal studies on rodents with weight changes as a primary outcome were included. The assessments of risk of bias and heterogeneity were conducted using the Cochrane Risk of Bias tool and I-square (I2) statistic respectively. RESULTS According to our findings the overall effect of boron administration orally was significant decrease of body weight (WMD = -18.12 g 95% CI -23.28, -12.96; P < 0.001). The boron compound administration was more effective in the borax form and also when the intervention duration was ≤ 4 weeks. Moreover, the effect size was greater in the male gender rather than female animals. CONCLUSION Most of the experimental studies supported the weight lowering effect of boron although, there are a few inconsistent evidences. It seems that the weight lowering effect of boron may be through increasing the energy metabolism, thermogenesis, lipolysis and inhibition of adiposeness. However, future clinical trials can better clarify the effects of boron on obesity management.
