Background: Polycystic ovary syndrome (PCOS) is an inflammation-related condition and a common metabolic disorder in women at fertility ages. The Dietary Inflammatory Index (DII) is a validated nutritional tool for estimating the inflammatory potential of the diet. It is assumed that a high DII score (indicating a predominantly inflammatory diet) has an association with higher odds of PCOS. The current study aimed to investigate the association between DII and PCOS risk in women. Methods: This case-control study was conducted in 2019-2020 on 120 newly-diagnosed PCOS cases and 120 healthy controls aged 18-45 years in Khorramabad, Iran. DII was estimated based on a validated 168-item Food Frequency Questionnaire (FFQ). Results: The mean±SD of DII in PCOS patients was 0.40±2.09, while it was 0.45±1.92 in the control group (P<0.001). There was a positive association between increasing DII score and the risk of PCOS (odds ratio= 2.41; 95%CI: 1.15-5.02, P for trend =0.006) in the crude model as the fourth quartile was compared with the lowest one. This association was still significant in several models after adjusting for age and energy intake (P for trend <0.001), in the model adjusted for the physical activity level, education status, and family history of PCOS (P for trend=0.003), and also after additional adjustment for BMI (P for trend= 0.003). Conclusions: The present study revealed that consuming more pro-inflammatory diets with higher DII scores is related to an increased risk of PCOS.

Background: Ecological conditions can change infection routes and increase the risks of outbreaks. The aim of this study is risk assessment of foodborne disease outbreaks based on dispersed regional climatic and demographic variables in Yazd Province, Iran. Methods: In this cross-sectional study, data of temporal climatic parameters and regional demographic factors linked to bacterial foodborne diseases were addressed. A multi-level regression analysis model was used to detect associations between the risk of outbreaks and ecological risk factors; the relationships were verified using (P<0.05). Results: Significant associations were observed between the outbreaks and age )P<0.001(, community type (P<0.001), temperature (P=0.04), rainfall (P=0.03) and dust pollution (P<0.001) in scattered parts of the province. The maximum rate of outbreaks was seen in spring, while the frequency of the outbreaks increased during April and October, compared to other months of the year (2012–2016). Conclusion: Consequences have revealed interventions of the environmental exposures in transmissions of microbial agents by complex ecological processes that caused the outbreaks.

Background: There is little knowledge about healthy and sustainable diets (HSDs) in Africa. This study assesses women’s readiness to adopt HSDs and its associated factors in Enugu, Nigeria. Methods: This was a cross-sectional household survey in 2021, which assessed women’s (n =450) food choice motives, perceived benefit, and readiness to adopt HSDs. The diets were categorised as pre-contemplation and contemplation (PC/C), preparation and relapse (P/R), and action and maintenance (A/M) stages. Odds ratios (OR) were generated using multinomial logistic regression. Results: Almost 57% of the women perceived HSD to be of high benefit. About 19%, 21%, and 60% of the women were in the PC/C, P/R and A/M, respectively. Low perceived benefit (OR=4.30, 95%CI: 2.30-8.05, P<0.001), low health concern (OR=6.35, 95%CI: 2.53-15.93, P<0.001), low education (OR=2.75, 95%CI: 1.39-5.44, P=0.004), and age <35 years (OR=2.48, 95%CI: 1.02-6.07, P=0.046) predicted being in the PC/C stage. Low perceived benefit (OR=2.75, 95%CI: 1.63-4.63, P<0.001), low health concern (OR=5.35, 95% CI: 2.40-11.92, P<0.001), low level of education (OR=1.90, 95%CI: 1.05-3.42, P=0.033), and being poor (OR=2.90, 95%CI: 1.05-7.97, P=0.039) predicted being in the P/R stage. Being <35 (OR=0.50, 95%CI: 0.28-0.87, P=0.014) and having low taste consideration (OR=0.29, 95%CI: 0.12-0.72, P=0.008) predicted being in the A/M stage. Conclusions: Readiness to adopt HSDs needs to be improved in Enugu, Nigeria. For this purpose, respective nutrition education interventions might be implemented regarding progress in HSDs.

Background: Non-alcoholic fatty liver disease (NAFLD) is regarded as a global health issue with increasing prevalence worldwide. Polyphenols play a pivotal role in alleviating inflammatory and oxidative stress pathways associated with the pathogenesis of NAFLD, however the literature are still scarce. Methods: This systematic review and meta-analysis was designed to investigate the association between dietary polyphenols and the risk of NAFLD with a meta-analysis approach. All observational studies in the online databases of PubMed, Scopus, Web of Science, Embase and Google Scholar up to June 2021 were searched, determining appropriate keywords, to identify relevant articles. Data were summarized using risk ratios (RRs) with 95% confidence intervals (CIs). Results: Of the total number of 4144 articles identified in the first phase of the literature search, 6 studies covering 21 arms on polyphenol intake and NAFLD risk containing 9436 participants in the case groups and 19996 participants in the control groups were included in study. The summary effect size (ES) for the risk of NAFLD, comparing the highest with lowest intakes of polyphenol, was 0.80 (95% CI: 0.77-0.83, P<0.0001, I2 = 0.0%;), indicating a significant inverse association. Conclusions: Our results proved that higher dietary intake of polyphenols can reduce the risk of NAFLD. However, due to small number of determined studies, these findings require further investigations to confirm recommendations for intensifying polyphenol intake in the general population.

Background: The aim of this study is to investigate the effect of endurance training with garlic and stevia supplementation on AgRP and α-MSH in the brain tissue of obese Wistar rats. Methods: 36 obese male Wistar rats fed with a high-fat diet (24 g fat, 24 g protein, and 41 g carbohydrate/100 g) were divided into six groups, including: 1) sham; 2) stevia supplementation; 3) garlic supplementation; 4) endurance training; 5) stevia supplementation plus endurance training, and 6) garlic supplementation plus endurance training. Moreover, 6 rats were included in the healthy control group to investigate the effects of obesity on the research variable. Training groups performed incremental endurance training for 15-50 minutes at a speed of 15-25 m/min, for eight weeks. Garlic and stevia supplements were added to the diet of the supplementation groups at a dose of 250 mg/kg. Results: Levels of AgRP in stevia supplementation group were significantly higher than endurance training (P=0.019) and endurance training plus stevia supplementation (P=0.018) groups. Levels of α-MSH in the garlic supplementation (P=0.001), endurance training (P=0.002), stevia supplementation plus endurance training (P=0.001), and garlic supplementation plus endurance training (P=0.001) groups were significantly higher than the sham group. In addition, in the endurance training plus stevia supplementation group, the levels were significantly higher than the stevia supplementation group (P=0.002). Conclusion: Endurance training plus garlic supplementation as well as endurance training plus stevia supplementation seem to play a synergistic role in appetite control protein; however, more studies on AgRP changes, following training and garlic and stevia supplementation are needed.

Background: While the broad issue of food security has generally received attention of the researchers, the particularities in hills and mountains has remained neglected. Thus, to provide some insights on food insecurity regarding mountain specificities, the current study aims to evaluate household food access of indigenous hill people in Meghalaya, India. Methods: Food access is a measure of household’s ability to acquire available food over a given period. In the current study, a sample of 900 people from indigenous population were randomly selected from rural Khasi, Garo and Jaintia Hills of Meghalaya. Household food access was explored with the following indicators: household wealth and income; household dietary diversity score (HDDS), and food consumption score (FCS). Data collection was done during December, 2019 to September, 2020. Results: The sample households are characterised by the predominance of marginal farmers (93% to 97%). Most of them were in the category of borderline food security with the FCS of between 21.5 to 35.0. Starchy staples were considered the main component of their diet. Their dietary diversity was significantly correlated with income (correlation coefficient=0.22) and wealth (correlation coefficient=0.38) at 0.01 level of significance. Conclusion: As dietary diversity at household is related to income and wealth, scarcity of income and wealth regarding indigenous hill population was an obvious reason for poor dietary diversity and the resultant poor dietary quality at the household level. To increase local food production and improve dietary diversity of indigenous hill people, revitalizing and strengthening local food systems is of great significance.

Background: In 2017, Turkey introduced Turkish Food Codex Regulation on labeling and providing food information to customers, which has been revised on a regular basis ever since. The purpose of this study was to survey food allergen information regarding foods and beverages sold in Turkey and the extent to which food allergens and precautionary allergen labeling (PAL) are emphasized in the products. Method: Thirteen food and drink categories were reviewed in five physical food stores and three online stores. A total of 1,010 foods and beverages were checked for allergens according to their labels. Results: 1,116 allergenic foods were identified in 59.7% of foods and beverages,. Gluten-containing cereals were clearly labelled in every food category, and milk received the highest number of declarations (30.55%), followed by gluten (27.42%), and tree nuts (9.67%). Snacks contained the most number of allergens (14.8%), followed by dairy products (13.8%), and baked products (12.4%). Conclusions: Accurate and understandable food allergy labeling is essential in avoiding food allergies. Food allergy labeling legislation especially The EU Regulation No. 1169/2011 establishes uniform rules for allergen labeling, which is one of the most stringent food regulations in the world. Current allergen labeling restrictions and policies need to be improved to reduce the risk of food hypersensitivity.

Background: Meat products contain sodium nitrite. Consumer demand for natural preservatives instead of synthetic ones in foods has been growing in recent years because of their safety. Today, good quality meat products are produced worldwide, and in addition to desirable sensory properties, they are cheaper than fresh meat. Sausage with 40% red meat is one of these products which can partially meet the need for animal proteins. Methods: In this study, sodium nitrite was replaced by lycopene pigment at concentrations of 200, 400 and 600 ppm in 40% meat sausage. Physicochemical properties of sausage samples including moisture, protein, ash contents and pH value were measured according to National Standard. Microbial tests (Clostridium, mold, yeast and Clostridium perfringens count) were performed according to National Standards. The colorimetric lightness index (L*) of the sausage samples was measured. Sensory properties (smell and taste) were compared with control sample (40% meat sausage contain 120 ppm sodium nitrite) after 30 days of storage. Data were analyzed using Duncan's one-way analysis of variance at 95% confidence level through Minitab 16 software. Results: After 30 days of storage, no significant (P>0.05) difference was found in physicochemical properties, microbial tests, lightness index (L*), and sensory properties among the samples. Conclusions: Since no significant difference was observed in microbial load and sensory scores between sausage sample containing 600 ppm lycopene pigment and control sample, 600 ppm lycopene pigment can be used in sausage formulation.

Background: This study aims to investigate cognitive determinants of functional foods (FF) consumption which contain fiber among Iranian students based on the theory of planned behavior (TPB). Methods: A cross-sectional study was carried out between March and May 2018 on the students of Birjand University of Medical Sciences (BUMS). A structured questionnaire was used which was validated with Cronbach’s alpha of 0.78. Results: 515 questionnaires were completed, and the majority of the respondents were females. 20% of the participants were the primary household food purchasers, and familiarity with functional foods was the only effective factor regarding consumption. Subjective norms could predict the students’ consumption of the macaroni which contained fiber. In addition, monthly income of the family had a major effect on having the macaroni containing fiber. The parents’ education also impacted the consumption of these foods. Conclusion: Attitudes and perceived control had a poorer effect on choosing the food containing fiber rather than subjective norms.
研究背景本研究旨在以计划行为理论（TPB）为基础，调查伊朗学生食用含纤维的功能性食品（FF）的认知决定因素。研究方法在 2018 年 3 月至 5 月期间，对比尔詹德医科大学（Birjand University of Medical Sciences，BUMS）的学生进行了一项横断面研究。研究采用了结构化问卷，该问卷的 Cronbach's alpha 值为 0.78。结果共完成 515 份问卷，大部分受访者为女性。20%的参与者是家庭食品的主要购买者，对功能食品的熟悉程度是影响消费的唯一有效因素。主观标准可以预测学生对含纤维通心粉的消费量。此外，家庭月收入对食用含纤维通心粉也有很大影响。父母的教育程度也会影响这些食物的食用量。结论与主观标准相比，态度和感知控制对选择含纤维食物的影响较小。

Background: Oxidative stress is the leading cause of chronic disorders. The aim of the present study is to assess the effects of conjugated linoleic acid (CLA) supplements on oxidative stress biomarkers in adults. Methods: PubMed, Web of Science, Google Scholar, ProQuest, Scopus, and Embase were searched up to December 2020. All clinical trials that evaluated the effect of CLA on malondialdehyde (MDA), GSH-peroxidase (GPX), and 8-IsoprostanesF2α (8-iso-PGF2α) were included. Results: Twelve eligible studies were included in the meta-analysis. A significant increase was observed in 8-iso-PGF2α level (SMD=1.48 nmol/mmol of creatinine; 95% CI: 1.11 to 1.85) with low heterogeneity level (I2= 31.5%, and P=0.199). This effect was also significant in both subgroups of healthy and metabolic disorder individuals. Moreover, after Hartung-Knapp adjustment, the results remained significant. No significant changes were found in MDA (SMD=-0.34 µmol/l; 95% CI: -0.82 to 0.14) and GPX (SMD=0.31 U/gHb; 95% CI: -0.03 to 0.66) levels. However, after Hartung-Knapp adjustment, the results became significant for GPX level (SMD=0.31, 95% CI: 0.04 to 0.59). Conclusion: CLA supplementation could significantly increase some markers of oxidative stress such as 8-iso-PGF2α level and GPX level, without any significant effect on MDA level.
