This study systematically reviewed the published data on pesticide residues in Iranian fruits and vegetables to clarify the gap in this issue.

The title and abstract of all articles were evaluated after removing duplicate articles (2289 articles) by two independent reviewers. Finally, 25 articles were found that reported pesticide residues in fruits and vegetables. There was a great variation in measurement methods and pesticides reported across studies, which precluded meta-analysis. Therefore, a summary of the included studies was only reported. Results: Twenty-four studies reporting pesticide residues in Iranian fruits and vegetables were included. The percentage of Iranian fruits and vegetables contaminated with pesticides exceeding the maximum residue limit (MRL) was less than 10% in most studies. Contaminated samples were collected mainly from cultivated areas such as fields, orchards, or greenhouses. Conclusion: Pesticide residues in food have not been systematically reported in Iran. It was found that only limited articles were published by academic societies on this issue. Considering the current scenario, there is an urgent need to facilitate reliable and continuous measurements of toxic residues in Iranian food.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139867995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most common side effects of fasting is constipation if fasted people do not follow a proper diet. Therefore, the purpose of this study is to review the effect of synbiotic foods on reducing and treating constipation in fasted people during Ramadan. Methods: Search engines including PubMed, Scopus, Embase, Science Direct, Google scholar, Magiran, and scientific information database (SID) were applied with keywords such as Fasting, Synbiotics, Constipation, Ramadan, Digestive System, Probiotics and Prebiotics to find related articles published up to 2022. Finally, 45 articles were included in the review. Results: Synbiotics are actually oral supplements and a mixture of probiotics and prebiotics. The use of these compounds, in addition to reducing the complication of constipation, has other benefits that can be a step towards reducing the use of drugs and changing lifestyle not only this month but also at other times. Conclusion: The use of fiber-containing compounds, beneficial for the activity of the gastrointestinal tract, both microbial and to improve its peristalsis, is especially necessary in the elderly, whose peristalsis has decreased due to aging. The placement of synbiotic foods such as synbiotic dairy products will help to control this complication due to the presence of prebiotics and beneficial probiotics.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139868039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since a large proportion of employees in Semirom are engaged in apple gardening, this study aims to investigate the effect of increasing the productivity of all factors of apple production in improving the level of food security in Semirom city. Methods: In order to answer the research questions, using Cochran's formula, 139 gardeners were selected and the required data were collected through interviews and completing a questionnaire by cluster sampling in 2020. First, the productivity of all factors of production and the level of food security of the surveyed households were measured using the Household Food Insecurity Access (HFIA) index. Results: The results of this analysis showed that gardeners are not in a good food security situation. Then, using Shazam software and estimating the coefficients of the variables in the logit model, the relationship between productivity and food security was investigated. The results showed that productivity had a positive and significant effect on food security of the studied farmers. Based on the final effect, the variables of productivity, income, and savings had the greatest effect on food security of the farmers. In order to create more employment and increase income for gardeners and their families, apple-related processing industries should be established. Conclusion: The results of the study showed that apple gardeners of Semirom do not have good food security. It is recommended that younger people be educated by experienced farmers in the region.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139868460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown that omega-3 fatty acids and genetic variants contribute to perceived stress. This study aimed to examine interactions between vitamin D receptor (VDR) gene FokI polymorphism and omega-3 fatty acids on perceived stress score and serum cortisol levels in nurses. Methods: A total of 268 Iranian nurses (248 women; 20 men) participated in this cross-sectional study. Omega-3 fatty acids and perceived stress score of participants were evaluated using a 3-day food record and the Perceived Stress Scale (PSS)-10, respectively. Serum cortisol concentrations were evaluated by ELISA. VDR FokI polymorphism was genotyped using the restriction fragment length polymorphism method. Results: No significant relationship was found between omega-3 fatty acids with perceived stress score or cortisol level in FF genotype carriers, but lower intake of PUFA was related to higher cortisol level (P=0.04) in Ff carriers. Significant interactions were observed between VDR FOKI polymorphism and intakes of eicosapentaenoic acid (EPA) (P Interaction=0.06), linoleic acid (P Interaction=0.06), and docosahexaenoic acid (DHA) (P Interaction=0.06) on serum cortisol, so that lower intake of EPA, linoleic acid, and DHA was associated with an increase in cortisol levels in individuals with ff genotype. Moreover, in carriers of ff genotype, lower intake of EPA was related to the elevated perceived stress score (P Interaction=0.06).
