Dietary recommendations for the consumption of Black Corinth Raisin (Vitis vinifera L.) in Islamic religious books and the low probability of distortion in such hadiths on the other hand, can have high scientific support to ensure the physiological health of individuals. Emphasis has been undertaken on continuous eating of the fruits/nuts in these books to prevent the forgetfulness, enhance the memory and happiness, and improve physical health. This review has investigated the published studies in details on properties of red/black grape regarding the mentioned issues.https://ijns.sums.ac.ir/article_48050_379d39d544303d1c2622383f073cf242.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201The Nutritive and Medicinal Properties of Tahini: A Review1721794805410.30476/ijns.2021.90294.1123ENLouayLabbanDepartment of Nutrition, Faculty of Pharmacy, Al Rasheed Private University, Dmascus, Syria0000-0002-0308-5148GhiathSumainahSyrian Private University, Dmascus, SyriaJournal Article20210224Tahini is an oily paste made from mechanically hulled and ground sesame seeds. Tahini is considered a condiment in many regions of the world primarily in the Middle Eastern countries from the Levant region including Syria, Lebanon, Palestine, and Jordan. Sesame seeds contain about 25-35% protein, as well as at least 55% oil, predominantly unsaturated fat from oleic acid (35.9-47%), linoleic acid (35.6-47.6), palmitic acid (8.7- 13.8%), stearic acid (2.1-6.4%), and arachidic acid (0.1-0.7%). Tahini is widely known as one of the natural health promoting foods that has the potential to prevent various health problems such as hypertension, hypercholesterolemia, cancer and aging. Additionally, it may be useful in managing oxidative stress-associated diseases, such as atherosclerosis, diabetes mellitus, obesity, chronic renal failure, rheumatoid arthritis, and neurodegenerative diseases including Alzheimer’s disease. Moreover, sesame oil has multiple physiological functions, such as decreasing blood lipids, increasing antioxidative ability and γ-tocopherol bioavailability, and providing anti-inflammatory function and a potential estrogenic activity. Many health promoting effects are attributed to its lignans that are consisted of sesamin and sesamolin. In sesame oils, the ranges of sesamin and sesamolin are 0.93-2.89 and 0.30-0.74 mg/g oil, respectively, with tocopherol contents of 304-647 μg/g oil. Lignans may increase antioxidant potential of diets and provide stability. Hence, this review will highlight and discuss the potential nutritional and health promoting effects of Tahini.https://ijns.sums.ac.ir/article_48054_7e6617b573577b4f28fc21f4722472fb.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201The Relationship between Body Mass Index and Eating Disorder Risk and Intuitive Eating among Young Adults1801884805810.30476/ijns.2021.91438.1138ENHacı ÖmerYılmazNutrition and Dietetics, Health Science Faculty, Gumushane University, Turkey0000-0003-4597-7758Tuba EdaArpa ZemzemogluNutrition and Dietetics, Health Science Faculty, Gumushane University, Turkey0000-0002-6836-4527Journal Article20210530Background: Obesity is a serious health problem that threatens public health. There are limited researches exploring the relationship between obesity and eating disorder risk and intuitive eating. The purpose of this study was to determine the rate of eating disorder risk and obesity, and identify the relationship between body mass index (BMI) and eating disorder risk and intuitive eating among young adults.<br />Methods: This cross-sectional study enrolled 1216 young adults. The data were obtained through a questionnaire consisted of three sections of socio-demographic information in the first part, Intuitive Eating Scale-2 (IES-2) in second part and Eating Attitudes Test-26 (EAT-26) in third part. Weight, height, and BMI of participants were also measured by<br />researchers.<br />Results: The overall overweight/obesity rate of the participants was 16% (male=25.9%; female=10.9%). The rate of eating disorders risk was 24.3% in general (male=21.5%; female=25.4%). Overweight/obese had higher eating disorders risk than normal and underweight (26.7%, 23.8%, 21.6%, respectively). IES-2 score of underweight was significantly higher than overweight/obese (3.33±0.35, 3.20±0.37, respectively).<br />Conclusion: This is the first study to examine the relationship between BMI and EAT-26 subscale showing that BMI was positively correlated with EAT-26 and negatively was correlated with IES-2 score. Therefore, BMI may be affected by eating behaviors and intuitive eating. Also, intuitive eating can be a new method of eating, and weight control and management.https://ijns.sums.ac.ir/article_48058_62879d3f5ebca457e502225b2828a42a.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201Relationship between Internet Addiction and Dietary Behaviors of Students, Studying in a Teaching Hospital1891934805310.30476/ijns.2021.91305.1136ENWishaWaheedDepartment of Clinical Nutrition, Nur International University, Lahore, Pakistan0000-0002-0524-3891WaraJamilDepartment of Biochemistry, Arid Agriculture University, Rawalpindi, PakistanTayyabaRahatPakistan Health Research Council, Islamabad, Pakistan0000-0002-4788-0194ShaziaZahraDepartment of Clinical Nutrition, Nur International University, Lahore, PakistanMeshaalPerwaizProvincial Food fortification Alliance of Pakistan, Civil Secretariat Office, Lower Mall, Lahore, PakistanSafeenaAmjadDepartment of Food and Nutrition, University of Home Economics, Lahore, PakistanQaiserRazaDepartment of Health Sciences, Faculty of Earth and Life Sciences, Vrije Universiteit, Amsterdam, The NetherlandsJournal Article20210520Background: Problematic Internet Use (PIU) as an impulse-control disorder including “internet addiction” is commonly described as “a person’s incapability to overcome their excessive internet use, which in turn leads to distress and weakening of daily functional activities”. This study aimed to determine the dietary behavior of internet addicts among students.<br />Methods: In a cross-sectional study in Fatima Memorial College of Medicine and Dentistry,<br />176 students aged 18-28 years were enrolled. A self-constructed questionnaire was used to evaluate demographic profile, level of internet addiction, dietary habits, physical activity, and snacking, and lifestyle patterns.<br />Results: Totally, 46.6% of students were mildly addicted to internet and 46% skipped the breakfast. Among internet addicted persons, snacking was found very common due to hunger, habit and lack of time for proper meal. The daily intake of fruits, vegetables, dairy, bread and cereal and meat was below WHO recommended amount and only 2.8% took appropriate amount. Only meat and fried food consumption were significantly and positively correlated with internet addiction.<br />Conclusion: The study findings showed that addiction of students to the internet is increasing day by day and its negative effects on dietary patterns are evident. There is a need to plan interventions focusing on reducing screen time and promoting healthy eating.https://ijns.sums.ac.ir/article_48053_a5512ba4863f8e7eacba0c7e10524f51.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201Effect of Germinated Black Rice Krisna Extract on Fasting Blood Glucose and Body Weight in Diabetes Mellitus Rats1942004805110.30476/ijns.2021.93204.1163ENSudana FatahillahPasaribuDepartement of Nutrition, Postgraduate, Universitas Sebelas Maret, Surakarta, Indonesia0000-0003-3937-6278BudiyantiWiboworiniDepartment of Nutrition, Faculty of Medicine, Universitas Sebelas Maret, Surakarta, Indonesia0000-0002-5561-4451Lilik RetnaKartikasariDepartement of Animal Science, Faculty of Agriculture, Universitas Sebelas Maret, Surakarta, IndonesiaJournal Article20211018Background: Diabetes mellitus (DM) is a non-communicable disease that is generally associated with fasting blood glucose (FBG) level of >126 mg/dL and weight loss. Germinated black rice krisna (GBRK) extract contains phytochemicals with antioxidant and anti-diabetic properties. The purpose of this study was to assess the impact of GBRK extract on FBG level and body weight (BW) in rat model of DM.<br />Methods: In an in vivo pre- and post-test study 36 male Wistar rats with BW design, of 150-200 g were enrolled and divided into 6 groups, including control (C), negative control (NC), GBRK 535 mg/kg BW (P1), GBRK 1070 mg/kg. BW (P2), and GBRK 2140 mg/kg BW (P3). Diabetes was induced using streptozotocin (STZ) and nicotinamide (NA) and the intervention period was 14 days. Measurement of FBG level was by quantitative enzymatic colorimetric test of Glucose Oxidase Phenol 4-Aminoantipyrine (GOD-PAP) and body weight was determined by a digital scale.<br />Results: The administration of GBRK extract in P1, P2, and P3 groups could significantly reduce the FBG (p <0.01). GBRK in P1, P2, and P3 groups could also significantly improve the body weight to normal state too (p <0.01).<br />Conclusion: GBRK extract at doses of 535, 1070, and 2140 mg/kg BW for 14 days was demonstrated to improve metabolic disorders in diabetes by reducing FBG level and improving the BW to the normal state.https://ijns.sums.ac.ir/article_48051_c13f6245baecdd127a7178c5054e2674.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201The Effect of High Dietary Salt Consumption on Renal Function in Streptozotocin-Induced Diabetic Male Wistar Rats2012074805210.30476/ijns.2021.92685.1153ENJerome NdudiAsiweDepartment of Physiology, PAMO University of Mefical Science, PortharcourtPhysiology Department, University of Ibadan, Nigeria0000-0001-5600-8288NicholasAsiweAnatomy Department, Delta State University, Abraka.Joy EneOnuhBiomedical Engineering Department, University of Ibadan, NigeriaJournal Article20210907Background: Salt consumption has been linked to increased risk of development of type 2 diabetes mellitus and hypertension due to its glucose resistance and body weight promoting effects. This study investigated the effect of high dietary salt intake on renal function in diabetic male Wistar rats.<br />Methods: Animals were divided into 4 groups (n=7). Group 1 (control group) were fed with normal rat chow, group 2 (Diabetic) were received streptozotocin (STZ, 60 mg/kg), group 3 (high Salt) were given 8% salt diet, and group 4 had both STZ (60 mg/kg) and feeding with 8% salt diet. Fasting blood glucose was measured weekly and after 28 days prior<br />to sacrifice, blood pressure measurements and 24 h urine samples were collected. After sacrifice, blood was collected and serum was separated for biochemical analysis. The kidneys were removed and preserved in 10% formalin for histological examination.<br />Results: Serum urea, creatinine and urine urea increased significantly (p <0.05) across group, when compared with control, while urine creatinine reduced (p <0.05) in all groups. There was a significant (p <0.05) increase in superoxide dismutase and catalase in high salt and salt/diabetes groups, when compared with diabetic group. Glutathione peroxidase significantly increased (p <0.05) across groups. Histologically, kidneys showed signs<br />of inflammation in diabetic group, hemorrhagic lesions in high salt group and both hemorrhagic lesions and inflammation in salt/diabetes group.<br />Conclusion: High dietary salt consumption was shown to affect tubular and glomerular functions by altering kidney histoarchitecture and antioxidant defense system.https://ijns.sums.ac.ir/article_48052_7c2210566a9d857d709c63f9da71d452.pdfShiraz University of Medical SciencesInternational Journal of Nutrition Sciences2538-18736420211201Comparison of Different Methods for Carotenoid Extraction from Dunaliella Salina2082154804810.30476/ijns.2021.93230.1162ENMaryamNejadmansouriDepartment of Food Science and Technology, School of Agriculture, Shiraz University, Shiraz, Iran0000-0003-3005-2058Mohammad-TaghiGolmakaniDepartment of Food Science and Technology, School of Agriculture, Shiraz University, Shiraz, Iran0000-0001-5173-1178MandanaFamouriDepartment of Food Science and Technology, School of Agriculture, Shiraz University, Shiraz, IranJournal Article20211012Background: Dunaliella salina (D. salina) is a unicellular marine alga known for its carotenoid ingredient. Carotenoid has been used in food industry as a coloring additive and as an antioxidant. In addition, it has anticancer, antiaging, and immune-modulatory properties. Different methods have been used for extraction of carotenoids from algae. This study evaluated different extraction methods for carotenoid and compared<br />the carotenoid yield and extraction time for procedures.<br />Methods: In an experimental study, D. salina was isolated from Maharloo Lake in Shiraz, Iran. D. salina was centrifuged, dried, and suspended in methanol for further carotenoid extraction using different methods, namely ultrasound-assisted, supercritical fluid, microwave-assisted, electromantle, magnetic stirring, and maceration extraction methods.<br />Results: Simultaneously, ultrasound-assisted, microwave-assisted, and electromantle extraction methods showed higher carotenoid yield and during a shorter time when compared with supercritical fluid, magnetic stirring, and maceration extraction methods. Since ultrasound-assisted extraction is a cold extraction method and ultrasound waves could release carotenoid and chlorophyll from broken cells to solvent quickly, the highest yields of carotenoid and chlorophyll were obtained during 10 min applying ultrasound-assisted extraction method. In contrast, the lowest yields of carotenoid and chlorophyll were undertaken by supercritical fluid extraction method.<br />Conclusion: Ultrasound-assisted extraction method was demonstrated to be a promising tool to recover higher value-added compounds from D.salina.https://ijns.sums.ac.ir/article_48048_8fe8c0e7baf3a1026ca814b3a9ffe4e4.pdf
