Background: Pistachio butter is produced from ground roasted pistachio nuts. Methods: In this study, different formulas of low-fat pistachio butter with 0, 5 and, 10% of pistachio meal and 0, 1 and, 2% of mono- and diglyceride were examined in terms of physicochemical, sensory, and nutritional characteristics. Results: In the fourth month of storage, the highest oil separation (12.4%) from the product was observed in pistachio butter without emulsifier and meal (P≤ 0.05). The most value of carbohydrates and the least value of oil content were observed in the pistachio butter containing 10% meal. The lowest anisidine and peroxide value was detected in the formula with higher content of emulsifier (2%). The pistachio butter formulas without or with 5% meal showed a better green color (lower 'a' value). The pistachio butter with higher values of the meal obtained the least spreadability score. Conclusion: The formula containing 1% mono- and diglyceride and 5% pistachio meal was selected as the best low-fat pistachio butter

Background: Observance of food hygiene is considered an important principle to prevent humans from contracting diseases and also to protect the environment from contamination. Health workers are on the front line forces of the health system. Therefore, promoting the health of health workers has an important role in promoting community health. The aim of this study is to investigate the determinants of food hygiene based on the Health Belief Model (HBM) in health workers in Urmia. Methods: In this descriptive-analytical study, 300 health workers in rural health centers of Urmia city were selected and entered into the study by census method based on inclusion criteria. Data collection tools included 3 parts: demographic characteristics, knowledge questionnaire, attitude and behavior, and health belief model questionnaire. Data were collected and analyzed using interviews. Results: The mean age of the workers was 36.76±7.61 year. The attitude and behavior of observing food hygiene had a statistically significant relationship with work experience, knowledge, attitude, gender, marital status, and level of education (P<0.05). Based on linear regression test, in all studied constructs, 30% of the variance of food hygiene behavior was explained. The predictive power of perceived efficiency was higher than other constructs (β=0.45). Conclusion: In designing educational interventions, the variables of self-efficacy, perceived benefits, perceived susceptibility, and perceived sensitivity should be emphasized as the most important predictors of food hygiene behaviors in health workers.

Background: In school age children, a healthy nutritional behavior can prevent double burden of malnutrition and chronic diseases. Nutritional education has a key role in adopting a healthy lifestyle. This study aims to evaluate the effectiveness of an educational package on the nutritional knowledge and practices, physical activity (PA), and body mass index (BMI) of elementary school children in Zahedan, southeast Iran. Methods: In this quasi-experimental before-after study, a total of 734 elementary school children, aged 10–14 years, recruited by census sampling method completed the survey. Each student received 8 hours of training and they were provided with a booklet that included a weekly chart for recording intake of food groups and PA by students for 3 months. A semi-structured questionnaire that included questions on the students' nutritional knowledge, eating behavior, PA performance, and BMI before and after the intervention was used for data collection. Paired t-test, McNemar's, and Friedman tests were used for data analysis. Results: Before the intervention, the mean score of nutritional knowledge was 7.5 and the prevalence of underweight and overweight/obesity was 17.4% and 0.4%, respectively. After the intervention, the results showed a significant increase in the nutritional knowledge scores, the number of days with 30 min PA per week, and the frequency of consumption of dairy products, animal protein, and fruits. Also, in comparison with before intervention, a significant decrease was found in the prevalence of underweight and overweight/obesity of school children after the intervention. Conclusion: This multifaceted nutritional education intervention was associated with improved nutritional knowledge score, PA, and being underweight in elementary school children.

Background: Cross-contamination between food, equipment, and contact surfaces during food processing may occur with some pathogenic bacteria, such as E. coli and S. aureus. This study was conducted to investigate the bactericidal potential of ozonized water spray in food contact surfaces (plastic, glass, steel, and ceramic) for the inactivation of E. coli and S. aureus isolated from traditional yogurt.
Methods: Two isolated bacteria were tested for antibiotic resistance and the strains were exposed to ozonized water with concentration of 4 mg/l for 0, 2, and 10 minutes and after drying on food contact surfaces (FCS).
Results: E. coli and S. aureus were defined as multidrug-resistant. Ozonized water inhibited two bacteria growth on the FCS after two minutes. On plastic, glass, and ceramic surfaces, E. coli was more sensitive than S. aureus, while S. aureus on steel surface was more sensitive than E. coli.
Conclusion: Based on the results, it is recommended to use the ozonized water spray at 4 mg/l concentration to disinfect surfaces in contact with food, especially glass and ceramic surfaces.

Background: White egg powder provides essential amino acids compounds. This study aims to investigate the theory that a regular consumption of white egg powder would improve weight gain and appetite in children with malnutrition. Methods: The present experimental study was conducted among children aged 3-6 years with mild to severe malnutrition referred to Ghadir Mother and Child Hospital affiliated with Shiraz University of Medical Sciences from April to October 2017. The malnourished children received egg white protein (1 g/kg of their current body weight) for 3 weeks. Weight loss as a primary outcome and weight-for-height Z-score (WHZ), height-for-age Z-score (HAZ), weight-for-age Z-score (WAZ), and BMI-for-age Z-score (BAZ) were measured as secondary outcomes, assessed at baseline and after six weeks of study. Results: Of the 23 children included, 20 finished the study. Weight increased in all children although it was not significant (P = 0.101). A lower appetite was seen at the end of the intervention, but it was not significant (P = 0.575). Malnutrition based on WHZ and BAZ decreased compared to the baseline measurement, while the changes were not significant. Regarding other markers, no statistically significant changes were found compared to the baseline measurement. Conclusion: The addition of white egg powder to complementary nutrition could not improve weight gain and appetite in malnourished children. Further research with a larger study population and longer intervention time is needed to demonstrate the clear effect of egg white on improving malnutrition in children.

Background: Magnetic nanoparticles attract increasing interest due to their use in cancer therapy and as drug carriers for several other diseases. The present study investigates the physiochemical properties of quercetin-conjugated superparamagnetic Fe3O4 nanoparticles and their effects on breast cancer cell line MCF-7. Methods: A simple precipitation method was used to prepare the Poly Ethylene Imine (PEI)-coated Fe3O4 nanoparticles; they were then conjugated with flavonoid-compound quercetin on the surface via carboxylic/amine group using nanoprecipitation method. Then, the physical and chemical parameters were calculated using Zeta-sizer, scanning electron microscopy (SEM), and extract release patterns at 37 and 42 0C. Finally, the toxicity level of this quercetin- conjugated nanosystem on the MCF-7 cells was investigated by MTT assay. Results: The results showed that the prepared nanosystem attained about 74% of quercetin inclusion, 91.2 nm size, 65.1 mV zeta potential, spherical morphology and a controlled release. Compared to Fe3O4 nanoparticles and pure quercetin, MTT and microscopy analysis revealed that quercetin-conjugated Fe3O4 nanoparticles induced considerable cytotoxicity, and morphology changes against MCF7 cells. Conclusion: Quercetin-conjugated Fe3O4 nanoparticles have appropriate physiochemical properties; they can be a suitable carrier for drug delivery and a promising therapy for candidates.

Background: There is a close relationship between food insecurity and diabetes. It has been shown that some socio-economic factors can affect Type I diabetes. This study was conducted to investigate the relationship between food insecurity and some socio-economic factors with type 2 diabetes in patients referring to Diabetes Clinic of Buali Hospital in Zahedan city. Methods: This case-control study was conducted on 450 patients with type 2 diabetes as the case group and 450 similar participants without diabetes as the control group in 2021. The data were collected for the demographic and socioeconomic characteristics and food insecurity by the 18-item USDA household food security questionnaire. Results: The results showed that food insecurity was significantly higher in case group (7.27±5.25) compared to the control group (6.44±5.82). Participants with higher income had lower food insecurity (P=0.0001). Married participants had higher food security compared to other status in both groups (P=0.0001). Individuals with higher education had better food security and diabetic individuals had lower education compared to healthy people (P=0.001). Employee and housewife in case group had higher food security compared to participants with other jobs (P=0.0001). Conclusion: Food insecurity was higher in diabetic patients and socio-economic factors had a close relation with food insecurity. Policy makers must consider strategies for improving socio-economic factors in Zahedan city.

Background: Obesity is an important predictor of diabetes. Defining the risk of diabetes among obese subjects is important for preventive health strategies. This study aims to compare the 5-year incidence of diabetes in obese and non-obese adult participants aged 20-70 years in a large population sample of central Iran. Methods: In this prospective study, 9964 people aged 20-70 years were selected between 2014 and 2015 using multi-stage cluster sampling from Yazd Greater Area, Iran. Participants with diabetes were excluded and non-diabetic individuals were evaluated for incident diabetes after a five-year follow-up. Logistic regression was used to find the association between obesity and 5-year incidence of diabetes in bivariate, and multivariate adjusted models for age, sex, physical activity, medical history, marital status, smoking, and education. Results: Out of the initial 9964 participants, 1383 (14%) were excluded due to prevalence of diabetes. The remaining 8413 (86.0%) participants were re-examined in 2019-2020. After five years of follow up, diabetes occurred in 6.6% (n=556) of the participants. The incidence of diabetes in obese men and women was 10.4% (n=109) and 9.9% (n=264), respectively; however, it was 4.5% (n=143) and 2.8% (n=40) in their non-obese counterparts (P<0.01). After multivariate analysis, obesity was associated with a higher likelihood of diabetes in men (OR=1.77, 95% CI: 1.33-2.35), women (OR=2.23, 95% CI: 1.55-3.21), and overall (OR=1.99, 95%CI: 1.60-2.48). Similar findings were obtained in participants aged under and over 60 years (P<0.05). Conclusion: There was a positive association between obesity and 5-year incidence of diabetes in an Iranian adult population. Interventions are required to change lifestyle in the adult population especially in younger participants to prevent obesity and diabetes.

Background: Sports nutrition knowledge is one of the essential needs of coaches. However, there is no standardized questionnaire in Persian to assess coaches' nutritional knowledge and information. Therefore, the purpose of this study is to evaluate the validity and reliability of Persian version of the Coach Sports Nutrition Questionnaire (CSNQ). Methods: CSNQ was translated-re-translated according to the WHO standard method, following Iranian culture and eating habits. The reliability of the questionnaire was assessed by test-retest method, correlation coefficient and internal reliability by Cronbach's alpha, and differential validity by independent t-test. 123 Iranian coaches completed the questionnaire. Results: The total internal reliability of the questionnaire assessed by Cronbach's alpha was 0.73. The intragroup correlation of the questionnaire, assessed by the test-retest method, was 0.71. Moreover, the comparison of the coaches with different levels of education was found to be significant (P < 0.001). Conclusion: The Persian version of the questionnaire regarding the coaches' nutrition sports knowledge has acceptable reliability and validity. It can help other studies and evaluate sports nutrition knowledge in Persian coaches.

Background: Since most studies evaluating the prevalence of hospital malnutrition in Iran have only been conducted on a specific group of patients, the present study was designed to investigate the prevalence of malnutrition in several different hospital wards. Methods: The nutritional status of 284 hospitalized patients was evaluated using the PG-SGA short form and compared according to demographic data and body mass index (BMI). Demographic and SGA domains were compared across BMI categories. Malnutrition degree was also compared. Results: Among the participants, 37.0% (n=105) had moderate malnutrition and 51.1% (n=145) had severe malnutrition. Comparing differences within patients according to their BMI status, there were no significant differences according to age, hospitalization duration, and current food intake status. Only sex and cause of hospitalization showed significant differences. Most of male participants had normal weight and were hospitalized for non-GI disorders (P=0.001 and 0.031, respectively). As expected, the scores obtained from weight, food intake, and symptoms sections of the questionnaire were higher in underweight patients in comparison to other BMI categories. Comparison of the same characteristics as per malnutrition status showed that people with high risk of malnutrition were older (P= 0.023), had oral food intake (P=0.007) and normal BMI (P=0.001). Conclusion: The number of patients at high risk of malnutrition was relatively significant in the study. A high frequency of malnutrition was observed among individuals with normal BMI. Screening tools in addition to BMI should be used to detect patients at risk of malnutrition.
