Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih; Yabancı Ayhan, Nurcan
The aim of the study was to compare the effects of acute intake dietary sugars on cognitive performance and reaction time. This study was, randomized, placebo-controlled, double-blind experimental design, conducted with 75 healthy adults. At the beginning of the study, the participants (36 male, 39 female; 21.6 ± 1.3 years of age; body mass index: 21.59 ± 1.94 kg/m2) were randomly divided into equal five groups (n:15) (glucose (10 g), fructose (10 g), sucrose (10 g), saccharin (0.24 g), placebo), and received dietary sugars dissolved in 200 mL of water. Cognitive performance was determined with Cancelation Test, and the Simple Response Time and Ruler Drop Tests were used in order to response and reaction time of participants, respectively. General score of cognitive performance (0.93 ± 0.1), reaction (295 ± 20 ms), and response (204 ms) were highest in glucose and lowest in placebo (0.63 ± 0.1; 368 ± 22 ms; 251 ms, respectively) (p <.001). Saccharin groups had a higher reaction (312 ± 22 ms) and response (216 ms) time score compared to consumed fructose (316 ± 39; 227 ms), sucrose (354 ± 26; 246 ms), and placebo (368 ± 22; 251 ms) groups, respectively (p <.001). These findings show that differences in the absorption pattern and sweetness levels of sugar types may have different effects on cognitive performance and reaction time.

Türkkan, Tuğba; Bülbül, Kenan; Yilmaz, Hacı Ömer; Meriç, Çağdaş Salih
This research was conducted determine the mediating role of eating habits in the effect of internet and smartphone addiction on body mass index. The study group consisted of 604 individuals aged between 18 and 45 years (Mean(Age) = 21.07, SD = 3.00). Data were collected using Young Internet Addiction Scale, Smartphone Addiction Scale Short Form and Three-Factor Eating Questionnaire. Findings show positive correlations between internet addiction and smartphone addiction with uncontrolled eating, cognitive restraint and emotional eating behavior. Internet and smartphone addiction were determined to positively predict emotional eating behavior, uncontrolled eating behavior and cognitive restraint. The direct effect and total effect of internet addiction on body mass index were insignificant. However results show that both smartphone and internet use by individuals affect body mass index mediated by eating behavior. This is the first study showing that smartphone and internet use both affected body mass index mediated by eating behavior. Research results emphasise the threat of addiction on physical health and suggest that educational and cognitive dietary interventions can contribute to healthy eating habits. Additionally, considering the internet may be used as an emotion regulation strategy, intervention programs may focus on developing emotion regulation skills aiming to develop coping ability for negative emotions to reduce emotional or uncontrolled eating.

Doğan, Gökcen; Tokaç Er, Nida; Öztürk, Meryem Elif; Meriç, Çağdaş Salih; Yilmaz, Hacı Ömer; Yabanci Ayhan, Nurcan
Aim: The aims of this study were to evaluate hand grip strength in young adults, to examine its relationship with anthropometric values, and to determine which values are predictive. Subject and methods: This prospective, cross-sectional study was conducted with 913 healthy young adults aged 18–30 years. A questionnaire form was administered in face-to-face interviews, and anthropometric measurements including height, body weight, waist circumference (WC), hip circumference (HC), mid-upper arm circumference (MAC), neck circumference (NC), triceps skinfold thickness (TSF), and hand grip strength (kg) were performed for each participant. Results: Hand grip strength was significantly higher for men than for women (p < 0.001), and was also higher in obese and overweight people compared to underweight participants (p < 0.001). Hand grip strength was correlated with weight, height, body mass index, MAC, TSF, WC, and NC (p < 0.001). The predictive ability of anthropometric measurements in estimating hand grip strength was thus demonstrated in a large population of healthy young adults. Significant regression was found, with an R2 value of 0.556. Hand grip strength increased by 0.282 kg for each centimeter of height and by 0.135 kg for each centimeter of MAC. The hand grip strength of male participants was 0.424 kg greater than that of females. Height, MAC, TSF, and sex were significant predictors of hand grip strength. Conclusion: According to our results, variability in hand grip strength among healthy subjects can be explained by height, MAC, TSF, WC, HC, age, and sex. The estimation of hand grip strength could be established based on these demographic and anthropometric variables.

Türkkan, Tuğba; Bülbül, Kenan; Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih
Giriş ve Amaç: İnternet bağımlılığı özellikle fizyolojik, psikolojik ve sosyal gelişimin hızlı olduğu, başta beslenme olmak üzere çoğu alışkanlıkların kazanıldığı çocukluk ve adölesan dönemi etkilemektedir. Bu araştırma, adölesanlarda internet bağımlılığının beslenme alışkanlıkları ve vücut ağırlığı-obezite (BKİ/Z-Skor) ile ilişkisini değerlendirmek amacıyla planlanmış ve yürütülmüştür. Gereç ve Yöntemler: Tanımlayıcı-kesitsel tipte olan bu araştırmaya basit rastgele örneklem metodu ve yüz yüze görüşme tekniği kullanılarak 679 adölesan dahil edilmiştir. Araştırmacılar tarafından güncel literatürün taranmasıyla hazırlanan anket formu adölesanların sosyo demografik özelliklerini, beslenme alışkanlıklarını, Türkiye Beslenme Rehberi’ne (TÜBER) göre günlük tüketilmesi gereken besin gruplarını, adölesanların fiziksel aktivite düzeylerini, internet ve akıllı telefon kullanım durumları ile “Young İnternet Bağımlılığı Ölçeği–Kısa Form (YİBÖ-KF)”unu içermektedir. Bulgular: Yaş ortalaması 14,06±2,06 yıl olan adölesanların BKİ ve Z-skor ortalamaları sırasıyla 20,67±3,7kg/m2 ve 1,24±1,10’dur. Z-skor’a göre adölesanların %77,0’ı zayıf/normal, %23,0’ı şişman/obez olarak kategorize edilmiştir. Şişman/obez adölesanların zayıf/normal olanlara kıyasla internet ve akıllı telefon kullanım sürelerinin anlamlı olarak yüksektir. Adölesanların YİBÖ-KF puanları 26,2±7,6 olup şişman/obez adölesanların puanları (27,8±7,0) zayıf/normal olanlara kıyasla (25,7±7,7) anlamlı olarak yüksektir. TÜBER’in günlük önerdiği düzeyde süt ve süt ürünleri, ekmek ve tahıl ürünleri ile sebze tüketen adölesanların internet bağımlılık düzeyleri bazen tüketen veya hiç tüketmeyenlere kıyasla anlamlı olarak düşüktür. Adölesanların Z-skorları ile internet bağımlılıkları arasında kuvvetli pozitif korelasyon belirlenmiş olup adölesanların internet bağımlılıkları arttıkça Z-skorları ve obezite riskleri de artmaktadır. Sonuç: Araştırma bulguları adölesanların önemli ölçüde sağlıksız beslenme alışkanlıklarına sahip olduklarını, sağlıklı besin gruplarını günlük önerilen düzeyde tüketmediklerini ve bu durumun internet bağımlılığı ile ilişkili olduğunu göstermiştir. İnternet bağımlılığı ve beslenme alışkanlıkları ile anormal vücut ağırlığı arasındaki ilişkinin objektif ölçümler ile detaylıca irdeleneceği, geniş ölçekli ileriye dönük çalışmalara ihtiyaç vardır.

Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih
Buckwheat (Fagopyrum esculentum Moench and Fagopyrum tataricum (L.) Gaertn.) is believed to have originated in central Asia. Chiefly cultivated in India, Nepal, China, North Korea, Russia, and Japan, it is a pseudocereal containing high protein, dietary fiber, vitamins and minerals, polyunsaturated fatty acids, and important antioxidants and phenolic compounds. In addition to its high protein bioavailability and economic value, it is an important alternative food with high nutritional value, suitable for the diet of celiac patients because it does not contain gluten. Buckwheat has gained worldwide importance because of the presence of some important bioactive constituents such as rutin, orientin, vitexin, quercetin, isovitexin, and isoorientin; other essential components like fagopyritols find vast potential for glycemic control in type 2 diabetics, positive cardiovascular effects, treatment of celiac disease, prevention of gallstones, and several hormone-dependent tumors. Currently, various products of buckwheat like flour, bread, biscuits, cookies, muffins, cakes, pasta, noodles, crackers, chips, and various fermented products and desserts are available in the market. Buckwheat has attracted worldwide attention, especially from food scientists, for its healing effects over chronic diseases. This chapter focuses on buckwheat in diets of the Middle East and its important effects on health.

Meriç, Çağdaş Salih; Yabanci Ayhan, Nurcan; Yilmaz, Hacı Ömer
Background/Purpose: This study was carried out to evaluate the nutritional status of elderly who received home health care. Methods: A total of 120 elderly were included in this cross sectional study. Elderly were visited in their homes and nutritional status of them was evaluated by Mini Nutritional Assessment-Short Form (MNA-SF) scale. In questionnaire; general information about elderly, presence of chronic disease, pressure sores, anthropometric measurement, nutritional status of elderly were asked. In addition, current biochemical parameters which were routinely evaluated in elderly were recorded by the researcher. Results: The mean age of elderly (40 males and 80 females) was 81.3±8.3 (65-105) years, and 97.5% of elderly were diagnosed with at least one disease. According to the MNA-SF score, 60.8% of elderly were classified as malnourished, 34.2% at risk for malnutrition and 5.0% as normal nutritional status. Currently, 49.2% of malnourished elderly have pressure sores and 54.8% had at least once before; these rates were higher than elderly without malnutrition (p <0.001). In addition, total MNA-SF score of elderly is strongly positive with hemoglobin, hematocrit and calf circumference; it was found that there was a strong negative correlation with C-reactive protein (CRP). Conclusion: In this study, it was found that only 5.0% of elderly who received home health care were in good nutritional status and pressure sore was higher in elderly who have risk of malnutrition or malnourished. Nutritional status of elderly receiving home health care should be evaluated by dietitians and more comprehensive scientific studies are needed.
