Öğe Added sugars and non-nutritive sweeteners in the food supply: Are they a threat for consumers?(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2022) Bayram, Hatice Merve; Öztürkcan, S. ArdaBackground & aims: Excess sugar intake can cause chronic diseases such as obesity, diabetes, and cardiovascular disease. Thus, limiting the intake of sugar in the diet is an important preventive measure. Food manufacturers have considered non-nutritive sweeteners (NNS) as an alternative to sugars. To date, there has been no systematic monitoring of the types of added sugars and NNS in Turkey's food supply. The aim of this study identified the added sugars and NNS in packaged foods and beverages that were available in supermarkets across Turkey. Methods: A cross-sectional study was conducted from April to December 2020. Three supermarkets in Turkey were chosen for this study. Results: Of the 2514 packaged foods and beverages analyzed, 1647 (65.5%) contained added sugars or NNS. Out of 1647 products, 9.7% contained both added sugars and NNS; 86.5% only added sugars whereas 3.8% had only NNS. The most used added sugar was white sugar in all food groups (50.6%e100%) while the most used NNS was sorbitol (28.4%). Conclusion: The use of added sugars and NNS in Turkey's food supply was found to be high, and white sugar being the most used sweetener in products available in the food supply. Therefore, it may be important to start monitoring the prevalence of products containing added sugars and NNS due to their negative health effects.Öğe AI showdown: info accuracy on protein quality content in foods from ChatGPT 3.5, ChatGPT 4, bard AI and bing chat(Emerald Group Publishing Ltd, 2024) Bayram, Hatice Merve; Ozturkcan, ArdaPurpose - This study aims to assess the effectiveness of different AI models in accurately aggregating information about the protein quality (PQ) content of food items using four artificial intelligence (AI) models - ChatGPT 3.5, ChatGPT 4, Bard AI and Bing Chat.

The aim of this study is to investigate nutritional status, body composition and biochemical parameters following SG. Methods: This was a prospective study, the subjects were patients who underwent SG at a special obesity clinic in _ Istanbul, Turkey, between 01.05.2017 and 01.11.2017. The mean body mass index (BMI) of the participants was 42.15 ± 4.84 kg/m2 for men and 41.44 ± 4.34 kg/m2 for women, preoperatively. Nutritional status, some anthropometric measurements and blood sampling were taken at each visit. Data were collected and analyzed for the present study at the following periods: pre-operation (pre-op), 1 month, 3 months and 6 months after surgery. Results: A total of 47 SG patients (20 men, 27 women) were evaluated. The mean BMI was 30.23 ± 3.56 kg/m2 for men and 30.35 ± 4.36 kg/m2 for women after 6 months and the amount of excess weight loss (EWL) increased in the 3 months (p < .001). Mean energy, fiber, vitamin A, vitamin C, vitamin B1, niacin, vitamin B12, folate, calcium, magnesium, iron, zinc, phosphorus and iodine were above the Dietary Reference Intake (DRI) recommendations. A significant association was found between protein intake and fat free mass loss in both genders after SG at 6 months (p < .05). Conclusion: Nutrition deficiencies are common for patients after SG. Therefore, it is important to routinely monitor these patients with a professional team.Öğe The Association between BMI and Body Weight Perception among Children in Turkey: A Cross-Sectional Study(Iranian Scientific Society Medical Entomology, 2023) Demir, Halime Pulat; Bayram, Hatice MerveBackground: There is a complex relationship between body mass index (BMI) and body weight perception. The present study aimed to determine the relationship between BMI and body weight perception among middle-aged children.Methods: This study was cross-sectional, and conducted among 333 children (9-11 yr) from the largest public school in Istanbul, Turkey between Oct 2019 and Jan 2020. BMI was calculated as weight divided by height squared (kg/m(2)). Body weight perception was determined using a photograph figure rating scale. Data were analyzed using SPSS version 24.0. Results: Overall, 325 children (mean age 10.01 +/- 0.99 yr) completed the study. According to the BMI classification, 8.6% of children were severely underweight, 4.9% underweight, 68.0% normal weight, 8.3% overweight, and 10.2% obese. However, 38.8% of the children perceived themselves as overweight, 21.2% as underweight, 20.3% as normal, 10.3% as overweight, and 9.4% as obese. 59.1% of children underestimated their current body weight. On the other hand, 14.2% of children overestimated their current body weight. There were statistical differences between body weight perception and BMI (P<0.001).Conclusion: There was a discrepancy between body weight perception and BMI among middle-aged children. More than half of the children tend to underestimate their actual body weight. Therefore, evaluating the nutritional status of children and learning which body type children perceive can guide the preparation of individual nutrition programs.Öğe Association between neutrophil to lymphocyte ratio, handgrip strength and nutritional status in geriatric patients(Emerald Group Publishing Ltd, 2023) Epcacan, Elif; Gonul, Idil; Bayram, Hatice Merve; Gurbuz, MuratPurposeThis study aims to examine the relationship between neutrophil to lymphocyte ratio (NLR), handgrip strength (HGS) and nutritional status in non-critically ill patients and outpatients. Design/methodology/approachA cross-sectional study was conducted on 80 geriatric patients. Nutritional status was evaluated using the Mini Nutritional Assessment Short Form, Geriatric Nutritional Risk Index, some anthropometric and biochemical parameters. NLR was calculated from the complete blood count results. Data were analyzed using SPSS 24.0. FindingsWhile 38.3% of patients were malnourished or at risk of malnutrition, 61.7% had normal nutritional status. Mini Nutritional Assessment Short Form was not correlated with NLR, whereas it showed a weak positive correlation with HGS. According to the logistic regression analysis, age, HGS, hemoglobin and platelet to lymphocyte ratio were significant independent factors for predicting malnutrition or risk of malnutrition. The receiver operator characteristic curve analysis showed that the optimum HGS cut-off point for patients with malnourished or at risk of malnutrition was 13.2. In conclusion, HGS was associated with the nutritional status. NLR was not associated with nutritional status but associated with nutritional risk. Originality/valueIt is well known that malnutrition is a serious health problem among older adults, and it is important to assess the nutritional status of older adults because of the adverse health effects. In addition, to the best of the authors' knowledge, this is the first study to determine the relationship between NLR, HGS and nutritional status in non-critically ill patients and outpatients.Öğe Banka Çalışanlarının Yaşam Doyumları, Depresyon Durumları, Beslenme Alışkanlıkları ile Antropometrik Ölçümlerinin Değerlendirilmesi: İstanbul İli Örneği(İstanbul Gelişim Üniversitesi Yayınları / Istanbul Gelisim University Press, 2023) Pulat Demir, Halime; Bayram, Hatice MerveAmaç: Bu çalışmanın amacı banka çalışanlarının yaşam doyumları, depresyon durumları, beslenme alışkanlıkları ile antropometrik ölçümlerinin değerlendirilmesidir. Yöntem: Bu tanımlayıcı ve kesitsel çalışma, 146 (%62,3 erkek, %37,7 kadın) bankacı üzerinde yürütülmüştür. Katılımcılara yüz yüze görüşme yöntemiyle demografik özellikler, beslenme bilgisi ve alışkanlıkları ile ilgili soruları içeren anket formu, Yaşam Doyum Ölçeği (YDÖ) ve Beck Depresyon Ölçeği (BDÖ) uygulanmış ve antropometrik ölçümleri alınmıştır. Veriler SPSS 24.0 paket programı ile analiz edilmiştir. Bulgular: Katılımcıların YDÖ puanları erkeklerde 14,52±6,58, kadınlarda 15,55±7,13 olup, BDÖ puanları sırasıyla; 6,44±5,56 ve 8,44±8,22’dir. BDÖ sınıflamasına göre katılımcıların %92,4’ünde depresyon semptomu olmadığı bulunmuştur. YDÖ ile BDÖ arasında negatif yönde zayıf bir korelasyon saptanmıştır (r: -0,386;p: 0,001). Bankacıların çoğu sağlıklı beslendiğini düşünse de çalışırken atıştırmalık olarak %51,4 oranında sağlıksız atıştırmalık tükettikleri tespit edilmiştir. Ayrıca psikolojik durumların yeme isteğini etkilediği gözlenmiştir (p<0,05). Beden Kütle İndeksi (BKİ)’ne göre erkeklerin %61,5’i ile kadınların %22,2’si; bel/kalça oranlarına göre ise erkeklerin %30,8’i ile kadınların %14,5’inin obezite riski olduğu saptanmıştır. Sonuç: Çalışmaya katılan bankacıların büyük çoğunda depresyon riski olmadığı ve yaşam doyumlarının yüksek olduğu saptansa da, çoğu sağlıklı beslendiğini düşünmesine karşın, yarısından fazlasının sağlıksız atıştırmalık tükettiği ve obezite risklerinin olduğu görülmüştür. Bu nedenle yoğun ve stresli bir çalışma ortamında çalışan banka çalışanlarının yaşam doyumları ile beslenme bilgilerini arttırmaya yönelik kurum içi eğitimler verilebilir. Ayrıca diyetisyen tarafında ideal vücut ağırlığa ulaşmalarını sağlamak ve sağlıklı beslenme alışkanlıklarını geliştirmek amacı ile eğitimler düzenlenebilir ve bireysel beslenme planlamaları hazırlanabilir.Öğe Beslenme Durumunun ve Beslenme ile İlişkili Bazı Hastalıkların Saptanmasında Boyun Çevresi Ölçümü(Kafkas Üniversitesi Tıp Fakültesi, 2021) Bayram, Hatice Merve; Margot Çelik, Zehra; Güneş, Fatma EsraBesin ögeleri alımı ile besin ögeleri gereksinmesi arasındaki dengenin sağlanması optimal sağlık için önem taşımaktadır. Beslenme durumunun saptanması bu açıdan önemlidir. Boyun çevresi ölçümü (Neck circumference-NC) beslenme durumunun saptanmasında kullanılan antropometrik ölçümlerden biri olup, karmaşık yöntemlere gerek kalmadan sonuca ulaşmaya yardımcı olan basit bir tekniktir. Ayrıca NC erişilebilir ve ölçümü kolaydır, bunun yanı sıra gün içerisinde değişiklik göstermediği için kullanılabilirliği araştırılmaktadır. Bu derlemenin amacı, NC ölçümü ile diğer antropometrik ölçümlerin, beslenme ile ilintili bazı hastalıkların, ilgili biyokimyasal bulguların ve metabolitlerin arasındaki ortaya konulmuş ilişkilerin incelenmesidir. Bu amaçla yapılan literatür taraması sonucunda, NC obezite ve metabolik sendrom riski ile yüksek korelasyon göstermesinin yanı sıra diğer antropometrik ölçümlerle de (vücut ağırlığı, beden kütle indeksi, bel çevresi, kalça çevresi ve bel/kalça oranı) ilişkili olabileceği görülmüştür. Ayrıca NC, insülin direnci, tip 2 diyabet, hipertansiyon, hiperlipidemi, kardiyovasküler hastalıklar ve obstrüktif uyku apnesi sendromunun tanımlanmasında kullanılabilecek bir ölçüm aracı olarak görülmektedir.Öğe Bioactive components and biological properties of cornelian cherry (Cornus mas L.): A comprehensive review(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2020) Bayram, Hatice Merve; Öztürkcan, S. ArdaToday, medicinal plants are very popular due to preventing many diseases and associated complications. Cornus mas L. (CM), is a member of Cornaceae family, is widely used in folk medicine for the treatment of a wide range of diseases such as diabetes, digestive ailments, anemia, liver and renal diseases, among others. The aim of this review is to present an overview of CM’s biological properties and usefulness as a nutritional supplement. CM fruits contain high levels of anthocyanins and iridoids while the leaves contain higher phenolic acids. The therapeutic effects of CM include anti (-oxidant, -microbial, -diabetic, -atherosclerosis, -obesity, -glaucoma); (cyto-, neuro-, cardio-, liver-, renal-) protective; hypo (-lipidemia and -tensive) have been found in reported studies, but clinical studies are limited. CM is rich in polyphenols, vitamin C and minerals, resulting in it being a “superfood”. Large-population and long-term clinical studies are needed to evaluate the biological activities of CM.Öğe Bioactive Components of Berry Fruits and Their Effects on Human Health(Sidas Medya A.S., 2022) Bayram, Hatice Merve; Öztürkcan, ArdaBerry fruits and their products are known as “functional foods” and have a growing interest in the food industry. Berries have high antioxidant capacity and anthocyanin contents in comparison to other fruits, and they are considered to have protective effects on human health by reducing the risks and symptoms of diseases. Although Turkey is in a prominent position with fruit production, having in the fifth place in the world according to the 2019 Turkey Statistical Institute (TUIK) data, the amount of berry fruit production is low, and its importance is still poorly understood. For this reason, it is very important to increase the interest in berry fruits, which are thought to have a positive effect on health, in our country, both scientifically and economically in order to increase their production. This review aims to evaluate the bioactive compounds of berry fruits and their health effects on human with clinical studies conducted in the last decade. To reach this goal, a literature search was conducted in DergiPark, PubMed, Elsevier and Google Scholar databases and a total of 32 international clinical studies were included in this non-systematic review. No clinical human study was found in Turkey. Results showed that berry fruits have anti-oxidant, anti-inflammatory, anti-diabetes effect and protective effect on the cardiovascular system, effect of improved lipid metabolism, anti-hypertension effect, and reducing effect of colon cancer symptoms and beneficial effects on microbiota by positively affecting human health. More clinical studies are needed to understand the exact mechanisms and long-term effects. © 2022 Sidas Medya A.S..

ArdaGünümüzde dünya nüfusunun artması ile birlikte insanlığın, kaynakların tükenme tehlikesi ile karşı karşıya kalması beklenmektedir. "Sürdürülebilir Beslenme" kavramının amaçlarından biri kaynakların gelecek kuşaklara aktarılabilmesidir. Bunun için yapılabileceklerin başında geleneksel beslenme modellerini ve beslenme alışkanlıklarını; çevreye ve sağlığa yararlı beslenme modelleri ve alışkanlıkları ile değiştirmek gelmektedir. Bunun yanı sıra sürdürülebilir beslenme için besin ögesi içerikleri hayvansal protein kaynaklı besinlere yakın olan, herkes tarafından erişilebilir ve kabul görebilecek alternatif protein kaynakları bulmak önemlidir. Son yıllarda ülkemizde bu kavramın önemi artmış durumdadır. Bu derlemenin amacı, sürdürülebilir beslenme ve çevresel etki açısından devamlılığı en fazla olan bitkisel kaynaklı besinleri temel alan beslenme modelleri ile gelecek yüzyıllarda sera gazı etkisini azaltmak için tüketilebilecek alternatif protein kaynakları hakkında insanların bilinç düzeyini artırmak adına kapsamlı bilgi sunmaktır.Öğe Comparison of several anthropometric measurements and blood lipid‑related indexes in metabolic-dysfunction associated fatty liver disease in adults: A cross-sectional study(YILDIZ TECHNICAL UNIV, YILDIZ CAMPUS, BESIKTAS, ISTANBUL 34349, TURKEY, 2024) Bayram, Hatice Merve; İliaz, Raim; Öztürkcan, S. Arda; Dündar, Bagnu; Güneş, Fatma EsraDyslipidemia is strongly related to metabolic-dysfunction associated fatty liver disease (MAFLD). Therefore, the lipid profile may be a potential indicator of defining MAFLD. Anthropometric measurements are widely used as simple and practicable tools to screen metabolic dysfunction, and no study determined the relationship between anthropometric measurements and blood lipid-related indexes. The aim of this study was to examine the relationship between several anthropometric measurements and blood lipid-related indexes in MAFLD patients. This study was conducted among 123 MAFLD patients in a private University Hospital in Istanbul, Turkey, between 01.06.2021 – 30.12.2021. Anthropometric and biochemical measurements were taken from all patients. Hepatic steatosis was determined using ultrasonography. SPSS was used to analyze the data. Neck circumference (NC) was moderately associated with triglyceride glucose index (TyG) in both genders. It was found that there was a moderate correlation between NC and cardiometabolic index (CMI), triglyceride (TG), and triglyceride to high-density lipoprotein ratio (TG/HDL-C) in women, whereas it was weakly correlated with CMI index in men. Neck-to-height ratio (NHtR) was moderately associated with CMI, and TyG indexes in women, while it was weakly correlated with TyG index in men. There was a moderate association between waist-to-hip ratio (WHR) and low-density lipoprotein (LDL-C) in women. However, it was only weakly correlated with CMI index in men. It was observed that the waist-to-height ratio (WHtR) was only linked with TyG index in men. Additionally, the body mass index (BMI) and blood lipid-related indicators had no association. Our finding suggests that both NC and NHtR could be used to predict the risk of dyslipidemia in MAFLD, especially among women.Öğe Consumers' opinions, use of food labels and knowledge of food additives(Emerald Group Publishing Ltd, 2023) Bayram, Hatice Merve; Ozturkcan, ArdaPurpose This study aims to determine what consumers take into consideration while buying food and to increase awareness. We also demonstrated food additives knowledge, and the association between food additive consumption and illness. Design/methodology/approach An online survey was used to collect data from respondents (n = 433). Findings Gender and knowledge of food additives and E numbers were found to be statistically different, as were education status and knowledge of food additives (p < 0.05). When purchasing foods, 40.0% of the respondents seldom read labels and also 34.9% were reading for each buy who verified the product's expiration date (94.2%), followed by brand name (84.8%). Sucralose, Acesulfame potassium (Ace-K) and aspartame consumption were associated with type II diabetes mellitus (T2DM). Additionally, sulfite consumption was linked to diarrhea/constipation. Research limitations/implications This study has some limitations. First, the study was cross-sectional, which does not allow the establishment of causal relationships for the associations found here. Second, the study was limited to one city in Turkey. Therefore, the study's findings cannot be extrapolated to Turkey. Practical implications Nutrition education should be given by the experts, and the policies should be implemented so that food labels may be used more effectively. Furthermore, nutritional education and policies can increase the general public's awareness of food additives. Social implications Nutrition education should be given by the experts, and the policies should be implemented so that food labels may be used more effectively. Furthermore, nutritional education and policies can increase the general public's awareness of food additives. Originality/value Consumers must be knowledgeable about food additives and E numbers. However, the findings revealed that the majority of Turkish consumers seldom read product labels, and the use of several food additives resulted in negative health repercussions. Therefore, professionals should provide nutrition education, and legislation should be put in place so that food labels may be used more effectively.Öğe Dietary habits, physical activity, sleep duration, and their association with overweight and obesity among children aged 6-10(Istanbul Medipol University, 2024) Demir, Halime Pulat; Bayram, Hatice MerveThis study aimed to determine dietary habits, the time spent on sleeping and physical activity among primary school children and to compare the responses given by the children and their parents about their dietary habits. This cross-sectional study was conducted on 282 children. A questionnaire including demographic characteristics, dietary habits, and some anthropometric measurements were performed. Physical activity and sleep duration were statistically different between overweight/obese and normal-weight children groups. The consumption of breakfast, lunch, fresh vegetables, dessert with dairy products, meat and meat products, chocolates, wafer, instant cake, pastry, and fast food was statistically higher in the overweight/obese group. Additionally, a statistical difference was found between “lunch consumption”, “junk food consumption” and “the child finishes all food on his/her plate” according to the responses of children and parents. It is important to raise awareness of healthy eating, exercise, and sleeping habits among primary school children. © 2024, Istanbul Medipol University.

(Cornelian cherry, CM) fruits were dehydrated by solar-drying (SD) and freeze-drying (FD), and in addition to sugar and mineral contents, the free and insoluble-bound phenolics were determined in fresh and dried fruits. After subjecting the sample to simulated in vitro digestion, the change of free and bound phenolics at gastric and intestinal digestion steps was evaluated in fresh and dried CM fruits. In fresh CM fruits, the total phenolic content (TPC) was dominated by the bound fraction, whereas the contribution of free phenolics to the total content (free + bound) became more dominant (731-1439 mg GAE/100 g dw) in the dried fruits. The bioaccessibility (BI%) of TPC from fresh CM after digestion was 193%, whereas it was 18.60 and 48.02% for SD and FD fruits, respectively. The contribution free fraction to the total TPC value was around 28% in nondigested fresh samples and increased to 94% in digested samples; however, in dried samples, it was 64% prior to digestion and only increased to 70% in digested samples. A total of 17 phenolic compounds were identified in CM fruits: chlorogenic acid, caffeic acid, epicatechin, quercetin, cyanidin-3-O-glucoside, and pelargonidin 3-O-glucoside were only detected in the free fraction; gallic acid, vanillic acid, ferulic acid, and kaempferol were detected in higher amounts in the bound fraction. The quantity of detected phenolics in the nondigested sample generally decreased from the gastric to the intestinal stage of digestion. The release of phenolics from the fruit matrix and their degradation occurred simultaneously during digestion, and this could be affected by the state of the fruit, e.g., fresh or dried.Öğe Effects of Cornus mas L. on anthropometric and biochemical parameters among metabolic associated fatty liver disease patients: Randomized clinical trial(Elsevier Ireland Ltd, 2024) Bayram, Hatice Merve; Iliaz, Raim; Gunes, Fatma EsraEthnopharmacological relevance: Cornus mas L. (Cornelian cherry, CM) fruits have been utilized for decades in numerous European and Asian countries as traditional cuisine and folk medicine. CM has antioxidant, anti-diabetic, anti-inflammatory, anti-obesity, and hypolipidemic activities due to its rich bioactive compounds, and CM fruits and other parts have been used for the prevention and treatment of a diverse variety of diseases in folk medicine. Obesity, insulin resistance, and inflammation are strongly associated with metabolic-associated fatty liver disease (MAFLD), therefore, CM may be hope for MAFLD patients.Aim of the study: The study aimed to evaluate the effect of lyophilized CM fruit powder with/without diet therapy on biochemical parameters and anthropometric measurements in patients with MAFLD.Materials and methods: This randomized clinical trial was conducted on 87 patients with MAFLD and 21 healthy individuals. Patients were randomly assigned into 4 groups: group-1 receiving 30 g/d lyophilized CM fruit powder plus diet therapy, group-2 receiving only diet therapy, group-3 receiving only 30 g/d lyophilized CM fruit powder, and group-4 had not undertaken any pharmacological treatment and diet therapy or lyophilized CM fruit powder for 8 weeks. Biochemical parameters, and anthropometric measurements at baseline and after the intervention were taken.Results: After 8 weeks of intervention, a significant decrease in body weight, body mass index, body fat mass, waist and hip circumferences, fasting blood glucose, insulin, hbA1c, liver enzymes, total triglycerides, low-density lipoprotein, total cholesterol were found in group-1, 2 and 3.Conclusion: Lyophilized CM fruit powder in addition to diet therapy and only diet therapy had a positive and similar effect on anthropometric measurements and biochemical parameters in MAFLD patients. Furthermore, only lyophilized CM fruit powder improved glycemic parameters. Therefore, lyophilized CM fruit powder may be beneficial for adult patients with MAFLD.Öğe Effects of Nutritional Status and Habits During Pregnancy on Term and Preterm Births(Eurasian Journal of Medicine and Oncology, 2018) Pulat Demir, Halime; İdiz, Cemile; Bayram, Hatice Merve; Yıldırım, SeldaObjectives: This study was designed to explore nutritional status and behaviors in pregnancy and investigate the effects on preterm and term births. Methods: The study was conducted with 120 mothers who gave birth (60 preterm and 60 term deliveries) in a private hospital between November 2015 and December 2015 in Istanbul. A questionnaire to record the demographic characteristics of patients, smoking and alcohol use, nutritional habits, and food consumption frequency was administered in a face-to-face interview. Results: In all, 65% of the births were by cesarean section and 35% were vaginal delivery; 41.7% of the preterm deliveries were in women aged ?35 years, whereas only 5% of term deliveries were in women aged ?35 years. Statistically significant differences were found in terms of education, work status, income level, smoking, pregnancy nutrition, and psychological status between preterm and term delivery mothers (p<0.05). Gestational weight gain was ?8 kg in 36.7% of mothers with preterm deliveries and ?12 kg in 36.7% of mothers and 8-12 kg in 68.3% of the mothers with term deliveries. Compared with preterm delivery mothers, term delivery mothers had fewer nutritional problems during pregnancy and more regular meal consumption (p<0.05). Conclusion: Weight gain and nutrition in pregnancy are variables that affect preterm birth. Hence, nutritional training should be provided regularly to pregnant women, and their weight should be monitored.Öğe Futbol İl Hakemlerinin Beslenme Alışkanlıkları, Besin Tüketimleri ve Antropometrik Ölçümlerinin Değerlendirilmesi(Türkiye Klinikleri Yayınevi, 2021) Pulat Demir, Halime; Bayram, Hatice MerveAmaç: Çalışmanın amacı, İstanbul ilinde bulunan futbol il hakemlerinin beslenme alışkanlıklarını, besin tüketimlerini ve antropometrik ölçümlerini değerlendirmektir.

Sonuç: Çalışma sonucunda futbol il hakemlerinin beslenme bilgisinin yeterli olmadığı, maç öncesi ve sonrasında bazı besin ögelerinin alımında farklılıklar olduğu, BKİ ve yağ oranlarının normal aralıkta olduğu bulunmuştur. Sporcular gibi hakemler için de vücut kompozisyonu ve besin ögesi ihtiyaçlarına göre bu alanda uzmanlaşmış diyetisyen tarafından sağlıklı ve dengeli beslenme programları ve eğitimlerinin düzenlenmesi performansları açısından faydalı olabilir.Öğe The greenhouse gas emissions from food consumption in Turkey: a regional analysis with developmental parameters†(Royal Society of Chemistry, 2023) Bayram, Hatice Merve; Ozturkcan, ArdaDue to the expected growth rate in world energy consumption in the near future, it is critical to estimate future energy consumption and associated environmental problems as precisely as possible. This study aims to describe total greenhouse gas emissions (GHGE) linked to different geographical diet profiles in Turkey, to map the environmental impacts that these generate. We used the last Address Based Population Registration System results to identify regions, populations, and some developmental parameters such as population density, the population growth rate, gross domestic product per capita, and socio-economic development scores, and the latest National Nutrition and Health Survey to determine the nutrient composition of Turkey's regional diets. The West Marmara diet had the highest GHGE levels, at 2983.79 g CO2-eq. per person per day, followed by the Istanbul diet and South-eastern Anatolia diet (2941.73 g CO2-eq. per person per day and 2935.08 g CO2-eq. per person per day) whereas the Mediterranean diet had the lowest, at 2623.90 g CO2-eq. per person per day. The contributions of beef and lamb to total diet weight (both were 0.98%) were lower than their contribution to total GHGE (21.65% and 21.04%). Our findings indicated that dietary changes could significantly help to reduce GHGE. Additionally, GHGE of diets might be associated with developmental parameters, but we did not find statistical differences. If the balance between natural resources and economic growth factors cannot be achieved in developing countries such as Turkey, which is a member of the United Nations, the environment will start to suffer and environmental sustainability will become a distant goal. Therefore, more studies are needed to confirm these results. © 2023 The Author(s).Öğe Greenhouse gas emissions in the food system: Current and alternative dietary scenarios(Ios Press, 2022) Bayram, Hatice Merve; Ozturkcan, S. ArdaBACKGROUND: There is a growing interest in diets due to the high contribution to greenhouse gas emissions (GHGE). OBJECTIVE: The study was aimed to estimate the impact on GHGE of replacing the current diet with eight alternative diets, which would be associated with GHGE, to contribute to the discussion of how dietary changes affect the GHGE. METHODS: The latest National Nutrition and Health Survey was utilized to determine the nutrient composition of Turkey's current diet, with eight dietary scenarios designed to meet the National Dietary Guidelines. RESULTS: The current diet had the highest GHGE with 3254.50 g CO(2)eq/person/day with beef, lamb, and cheese products accounting for the majority of emissions (18.61%, 17.15%, and 10.89%, respectively). The Model diet had a GHGE of 2994.18 g CO2eq/person/day, whereas vegetarian diets had the lowest (lacto-ovo vegetarian diet with 1944.95 g CO(2)eq/person/day and vegan diet with 1166.80 g CO(2)eq/person/day). Low energy efficiencies were associated with high diet-related GHGE levels. CONCLUSION: When evaluating future dietary guidelines for a sustainable diet, our study highlighted the need of integrating both health and environmental aspects. The present study found that dietary changes would significantly contribute to lowering GHGE. These findings will be beneficial in informing Turkey's nutrition, agriculture, and public policymakers.
