Nowadays, consumers are further interested in low saturated frying oils. Recently, manufacturers focus on eliminating palm oil derivatives (as a major vegetable source of saturation) from frying oil formulations. Therefore, achievement of balances between nutritional, technological and economic aspects is a big challenge for the oil industries. Materials and Methods: The aim of this study was to design and develop a palm-free frying oil formulation based on oils of sunflower (10–30%), canola (10–70%), corn (10–30%) and sesame (10–30%) using D-optimal mixture design. Linolenic acid (Ln) content, trans fatty acids (TFA), saturated fatty acids (SFA), oxidative stability index (OSI) and smoke point (SP) were considered as the response variables. To evaluate performances of these blends during deep frying processes (180 °C for 200 min), total polar compound (TPC) content, peroxide value (PV) and free fatty acid (FFA) content of the blends were assessed. Results: In summary, the total polar compound content, PV and FFA content of the blends included 15.87–19.41%, 16.41–20.58 meq O2/kg oil and 0.55–0.77%, respectively; fitted in published recommending ranges. All responses were fitted in the best way (R 2 > 0.91) to the linear model used for optimization. The optimal formulation included canola (40.675%), sesame (26.015%), sunflower (23.310%) and corn (10.000%) oils and all experimental values of this formulation were in the confidence interval.

The aim of the current study was to investigate effects of eight weeks of resistance training (RT) on myostatin gene expression in soleus muscles and insulin resistance in streptozotocin (STZ)-induced diabetic rats. Materials and Methods: In general, 14 Wistar male rats weighing 200–250 g and aging 8–10 weeks were selected for the study. Then, a newly prepared diabetic STZ solution was intraperitoneally injected to the rats. Animals were randomly divided into two groups of controls and resistance training diabetes. The resistance training protocol was carried out at ten repetitions as climbing up the ladder with 100% of the body weight for eight weeks, five days a week. Nearly 48 h after the last training session, soleus muscles of the rats were removed and the myostatin gene expression was assessed. Statistical data analysis was carried out using independent t-test at a significance level of P <0.05. Results: Results of the independent t-test showed that the mean expression rate of myostatin protein genes in rat soleus muscles of the resistance training group was significantly lower than that of the control group (P = 0.013). Furthermore, levels of glucose, insulin and insulin resistance were significantly lower in resistance training group, compared to those in control group (P-values of 0.001, 0.005 and 0.001, respectively). A significantly positive correlation was seen between the mean expression of myostatin protein gene and the blood glucose (P = 0.012, r = 0.539), as well as the expression of myostatin protein gene and the insulin resistance (P = 0.015, r = 0.525). Conclusions: Results of this study indicated that resistance training decreased myostatin expression and could improve insulin resistance in rats with type 2 diabetes. Hence, targeting myostatin might be a new therapeutic approach for the treatment of metabolic diseases such as obesity, diabetes and metabolic syndrome.","PeriodicalId":325113,"journal":{"name":"Nutrition and Food Sciences Research","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114773471","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}

The objective of this study was to investigate correlations between parental factors and nutritional status of the schoolchildren in a rural setting of Indonesia. Materials and Methods: This cross-sectional study was carried out during May 2018. Totally, 146 schoolchildren from ten primary public schools in Sepatan Timur, Tangerang, Indonesia, were involved in the study. Structured questionnaires were used to collect socio-demographic data (educational level, employment status and number of children) and estimated anthropometric measures (body weight and height). Digital weighing scales and standard microtoises were used to measure children weight and height, respectively. Anthropometric indices, height for age (HAZ) and body mass index for age (BAZ) Z-scores were calculated using WHO AntroPlus. Moreover, multiple regression analysis was used in the study. Results: Nearly 19.2, 11.6 and 16.4% of the schoolchildren were stunting, wasted and overweight, respectively. Maternal nutrition status were significantly associated with schoolchildren HAZ (β 95% CI = 0.367 [0.009–0.724]) and BAZ (β 95% CI = 0.926 [0.428–1.423]) scores. The BAZ scores of the children were inversely associated with maternal education levels (β 95% CI = -1.206 [-2.000; -0.441]).

This fruit is highly interested due to high quantities of anthocyanins. The bioactive compounds are often present in fruit tissues and should be released. The aim of this study was to extract bioactive compounds of black mulberries and assessment of heating process effects on the extracted compounds. Materials and Methods: Aqueous, ethanol and aqueous-ethanol solvents were used for the extraction processes. The physicochemical properties of extracts, including total phenol, total anthocyanin content, anthocyanin profile, antioxidant activity, acidity and total solids, were investigated. Then, the aqueous-ethanol extract was subjected to direct heating, microwave heating and non-thermal (gamma radiation) processes to assess their possible effects on the extract. Results: The aqueous-ethanol extract included higher total phenol (68.94 mg GAE/g) and anthocyanin contents (226.16 mg/ml), higher antioxidant activity (DPPH of 90.29% and FRAP of 1.42) as well as higher quantities of anthocyanins (cyanidin-3-glucoside, cyanidin-3-rutinoside and cyanidin-3-xyloside of 277.36, 53.21, and 11.44 mg/ml, respectively). It was observed that less time and power of heating, microwave and gamma radiation conditions included less deteriorative effects on anthocyanin compounds and thus a higher antioxidant activity was seen. Conclusions: Aqueous-ethanol solvents include further extraction efficiencies on phenolic compounds and anthocyanins and are considered as appropriate chemicals for the extraction of bioactive compounds from black mulberries. Furthermore, moderate heating conditions can preserve higher quantities of anthocyanins.","PeriodicalId":325113,"journal":{"name":"Nutrition and Food Sciences Research","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128867771","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}

In this study, effects of Cuminum cyminum essential oil (CCEO) and Biarum carduchcorum water extract (BCWE) and a combination of the two compounds on growth of L. monocytogenes and physicochemical, textural and sensory properties of lambs were investigated during cold storage. Materials and Methods: Effects of CCEO and BCWE on L. monocytogenes were investigated after a short time of cold storage using broth microdilution assay. Furthermore, physicochemical assessments of the lamb samples were carried out, including meat quality index (pH, color, texture) and sensory analysis. Gas chromatography-mass spectroscopy (CGMS) was used for the chemical analysis. Results: The GC-MS analysis showed that γ-terpinene (%12.57), β-pinene (%11.03), geranyl acetate (%10.81), pcymene (%9.95) and sabinene (%9.81) were the major components of the CCEO. Use of CCEO or BCWE alone decreased L. monocytogenes count to below 2 log CFU/g. Moreover, use of combined CCEO and BCWE decreased the number of L. monocytogenes to below the limit (2 log CFU/g) after 48 h. Conclusions: Results of the physicochemical parameters of the highlighted compounds revealed their useful values since these compounds showed improvement effects with no significant changes in meat quality.

Based on the epidemiological studies, RA is less severe in Southern Mediterranean regions, where fish, olive oil, fruits and vegetables are consumed in great quantities. Materials and Methods: This study was carried out in a case-control design. Totally, 100 RA patients (case group) and 100 age, gender and body mass index (BMI) healthy individuals (control group) were participated in the study. Dietary intakes were estimated using validated 160-item semi-quantitative food frequency questionnaire (FFQ). Food items of FFQ were grouped into 20 groups and dietary patterns were detected using principal component factor analysis. Associations between the adherence to dietary patterns and risk of RA were reported using logistic regression. Results: In general, two dietary patterns were detected, including Western dietary pattern, which was high in sweet snacks, high-fat meats, refined grains, high-fat dairies and salty snacks, and healthy dietary pattern, which was high in fishes, low-fat dairies, fruits, vegetables and olives. The RA patients had a significantly higher Western diet score than that the controls had (P < 0.001). However, no significant differences were seen in scores of healthy diet between the groups. The Western dietary pattern showed a significant positive association with RA either in the crude model (OR = 2.01, P < 0.001) or after adjustments of age, gender, education level, marital status, income, physical activity, smoking, BMI, dietary intake of vitamin E, saturated fatty acids and polyunsaturated fatty acids (OR = 4.28, P < 0.001).

The present study aims to develop new predictive equations for the Iranian people and to compare these equations with commonly used formulas. Materials and Methods: Total, 150healthy subjects aged 18-60 yrare invited to the Laboratory of Nutrition Research, National Nutrition and Food Technology Research Institute. Demographic data are gathered using a questionnaire. Then, anthropometric measures are taken and blood sampling is done for thyroid function tests. If the subject merits all the inclusion criteria, indirect calorimetry will be performed. The value of BMR will be predicted using common equations (Harris-Benedict, FAO/WHO/UNU, Miffilin). Differences between predicted (using equations) and measured (using indirect calorimetry) values are estimated. Correlations between the two sets of data is performed using Pearson or Spearman coefficients. Between-method agreement is checked using Bland-AltmanPlot. Accuracy of the predicted values using equations isconsidered as the proportion of participants whose calculated BMR is 90-110% of their measured BMR. Multiple regression analysis is employed to develop new predictive equations for the BMR based on the independent variables. Conclusions: Since facilities for the measurement of BMR may not be accessible in many clinical or research settings, BMR is usually estimated using predictive equations. However, several studies have reported inaccuracy of these equations for certain populations. Therefore, development of new population-specific predictive equations seems reasonable. These equations could hopefully reduce the energy estimation errors both in clinical nutritional interventions and community-based nutrition researches.","PeriodicalId":325113,"journal":{"name":"Nutrition and Food Sciences Research","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128454525","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}
