Diet quality and snack preferences of Turkish adolescents in private and public schools.

Introduction: Socioeconomic level is one of the important factors determining diet quality. Snack preferences are affected by socioeconomic level. The objective of this research was to determine the effect of socioeconomic levels on diet quality and snack preferences among adolescents from different socioeconomic backgrounds. Methods: The study involved 118 adolescents aged between 10-18 years residing in Istanbul. A questionnaire prepared by the researchers was used to obtain information on the adolescents' dietary habits, consumption of main meals and snacks, habits, and food consumption records. The participants' food consumption was assessed using the retrospective 24-hour recall method, and diet quality was evaluated using the calculated nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). Results: The mean age of the adolescents was 16.42±0.89 years. The number of snacks consumed in private schools was found to be higher than in public schools (p < 0.05). The NAR score for vitamin C consumption was significantly higher in private schools compared to public schools (p < 0.05). Although the MAR scores of adolescents in private schools were higher than those in public schools, this difference was not statistically significant. The majority of adolescents in private schools regularly consumed fresh fruit (67.2%), milk (60.3%), yogurt (60.3%), and nuts (56.9%) as snacks. In contrast, 45% of adolescents in public schools regularly consumed pastries (p < 0.05). Discussion: It was observed that adolescents studying in public schools had a lower tendency to prefer healthy foods for snacks compared to those in private schools. Socioeconomic level was identified as an important factor influencing eating habits during adolescence. Considering that the level of income is significantly different between the adolescents studying at private and public schools, the higher consumption of snacks by the adolescents studying at private school may be associated with higher income.

Mediterranean diet is associated with better gastrointestinal health and quality of life, and less nutrient deficiency in children/adolescents with disabilities.

Background: Children and adolescents with disabilities face various nutritional problems. This study aimed to examine dietary characteristics, nutritional status and problems, gastrointestinal health, and quality of life in children and adolescents with disabilities. Methods: This study included 5-18 years old children and adolescents (n = 1,991) with disabilities. We used the Mediterranean Diet Quality Index (KIDMED), the Gastrointestinal Symptom Rating Scale (GSRS), and the Pediatric Quality of Life Inventory (PedsQL) to assess diet characteristics, gastrointestinal problems, and life quality. We collected retrospective 24-h food record to assess energy and nutrient intakes. Results: The rate of stunting in children with disabilities varies between 16.5% and 19.8%. When comparing disability types, more children with physical disabilities were underweight (8.8% vs. 6.7%) and stunted (19.8% vs. 16.5%), while more children with intellectual disabilities were tall (7.9% vs. 5.5%) and overweight/obese (21.1 vs. 17.2%; p < 0.05). Wasting (9.3%) and overweight/obesity (23.8%) were more common in children with disabilities aged 5-7 years (p < 0.001). Eating problems such as loss of appetite, food refusal, food neophobia, and food selectivity were more common in children aged 5-7 years, and problems with fast eating and overeating were more common in adolescents aged 13-18 years (p < 0.05). Among children and adolescents with disabilities, the nutrients with inadequate intakes were vitamin E, vitamin B1, folate, potassium, calcium, and iron, while the nutrients with intakes above the requirements were proteins, carbohydrates, vitamins A, B2, B6, B12, and C, phosphorus, zinc, and sodium. Participants with good Mediterranean diet quality had higher energy and nutrient intakes and higher percentages of meeting nutrient requirements (p < 0.05). KIDMED scores were negatively correlated with GSRS total (r = -0.14, p < 0.001) and subcomponent scores (abdominal pain, diarrhea, reflux, indigestion, and constipation; p < 0.05), and significantly and positively correlated with PedsQL total (r = 0.12, p < 0.001). A one-unit increase in the GSRS score resulted in a 14.4 times decrease in the PedsQL score, and a one-unit increase in the KIDMED score resulted in a 10.8 times increase in the PedsQL score (p = 0.001). Conclusion: Overweight/obesity, stunting/wasting, nutritional problems, and deficiencies are common among disabled children and adolescents. Mediterranean diet is associated with a better quality of life, and gastrointestinal health in children with disabilities.

Effects of inulin on calcium metabolism and bone health.

Inulin, a dietary fibre found in the roots of many plants, has positive effects on health. It is particularly noteworthy due to its positive impact on calcium metabolism. Inulin has significant functions, such as improving calcium absorption through passive diffusion, bolstering calcium absorption via ion exchange and expanding the absorption surface of the colon by stimulating cell growth. In addition, inulin boosts calcium absorption by increasing calcium solubility, stimulating levels of calcium-binding protein expression and increasing useful microorganisms. It increases calbindin levels and stimulates transcellular active calcium transport. An inulin intake of least 8-10 g/day supports calcium absorption and total body bone mineral content/density in adolescents through its known mechanisms of action. It also significantly enhances calcium absorption and improves bone health in postmenopausal women and adult men. Sustained and sufficient inulin supplementation in adults has a positive effect on calcium metabolism and bone mineral density.

Dietary Patterns and Cardiovascular Risk: Are the Mediterranean Diet, the Heart-Healthy Diet, and Phytochemicals Associated with Lower Cardiovascular Risks?

Background: Dietary pattern may be one of the determinants of cardiovascular health. This study aimed to examine the relationship between a heart-healthy diet, the phytochemical content of a diet, and Mediterranean diet and cardiovascular disease (CVD) risks. Methods: This study was conducted with healthy volunteers (n=1446) from Turkey between August 2022 and September 2022. As risk assessment systems to determine CVD risks, SCORE (Systematic Coronary Risk Evaluation) and ASCVD (Atherosclerotic Cardiovascular Disease) were used. We utilized MEDFICTS (Meats, Eggs, Dairy, Fried foods, Fat in Baked Goods, Convenience Foods, Fats Added at the Table, and Snacks) to establish the suitability of the current diet for heart health, and MEDAS (Mediterranean Diet Adherence Screener) to examine the Mediterranean diet characteristics of the current diet. The phytochemical content of the diet was determined using the Phytochemical Index method developed by McCarty. Results: The lifetime and 10-year risk scores of SCORE and ASCVD were positively correlated with the MEDFICTS score (r=0.12, P<0.001; r=0.06, P=0.020; r=0.10, P=0.001, respectively). Mediterranean diet characteristics were correlated with lower CVD risk as per the SCORE categories (r=-0.07, P=0.009). A one-unit increase in MEDFICTS scores increased high-to-very high CVD risk and 10-year moderate-to-high CVD risk by 1.01 times, while a one-unit increase in the Mediterranean diet score decreased high-to-very high CVD risk and 10-year moderate-to-high CVD risk by 0.91 times and 0.95 times, respectively. In addition, high values of body weight, body mass index, waist circumference, waist-height ratio, and neck circumference were associated with higher CVD risk (P<0.001). Conclusion: Adopting a Mediterranean diet and a heart-healthy diet may be a good strategy to reduce CVD risks.

Migraine severity, disability, and duration: Is a good diet quality, high intake of phytochemicals and polyphenols important?

Objectives: Dietary pattern may be the determinant of migraine prognosis through various mechanisms such as systemic inflammation, vasodilation, cerebral glucose metabolism, and mitochondrial dysfunction.This study was conducted to examine the relationship of the symptoms and signs of migraine with dietary polyphenols and the phytochemical intake and the quality of the diet. Materials and methods: Individuals (n = 90), who were admitted to the headache outpatient clinic due to the diagnosis of episodic migraine, underwent physical examination by a neurologist. Migraine characteristics were assessed using the Migraine Disability Assessment Questionnaire and the Visual Analogue Scale. The Healthy Eating Index-2015 (HEI-2015) was used to evaluate the diet quality of individuals, and the Phytochemical Index developed by McCarty was used to determine the dietary intake of phytochemicals. Phenol-Explorer version 3.6 and the USDA Database for the Flavonoid Content of Selected Foods-Release 3.3 were used to calculate the dietary polyphenol intake. Results: Migraine severity was negatively correlated with the intake of phytochemicals and good diet quality (r = -0.37, p = 0.0003; r = -0.37, p = 0.0003, respectively), and with the intake of phenolic components flavanones (r = -0.27, p = 0.01) and lignans (r = -0.27, p = 0.01). With respect to the food groups; migraine severity was found to be inversely correlated with the total phenol intake from olive oil, oil, and fruits (r = -0.26, p = 0.01; r = -0.21, p = 0.04; r = -0.24, p = 0.02, respectively), and the flavonoid intake from olive oil, oil, fruits, and vegetables (r = -0.26, p = 0.01; r = -0.26, p = 0.01; r = -0.35, p = 0.0007; r = -0.22, p = 0.04, respectively). Strikingly, fruit flavanone intake was correlated with low migraine severity (r = -0.39, p = 0.0002), and fruit flavanol intake was correlated with low migraine disability (r = -0.21, p = 0.04). Conclusion: A high-quality diet rich in phytochemicals and polyphenols (especially flavanones and lignans) is associated with low migraine severity. Lower intake of phenols and flavonoids from vegetable oil, olive oil, fruits, and vegetables were associated with more severe migraine attacks. Examination of migraine characteristics and dietary pattern together with phytochemical and polyphenol intake may guide the development of dietary strategies to be used in migraine patients.

Evaluation of psychosocial status and nutritional awareness in municipal employees during the coronavirus disease 2019 outbreak: A cross-sectional study.

Background: Coronavirus disease 2019 emerged in China in December 2019 as a disease spreading from person to person by rapid droplet transmission, and which eventually evolved into a pandemic. Aim: This study aims to examine the psychosocial state, nutritional awareness, and physical activity level of municipal employees who provided services under changing working conditions during the coronavirus disease 2019 pandemic. Methods: A total of 220 employees working in two different municipalities in Istanbul were included in this study during March and April of 2021. For data collection, a questionnaire form was used. The form consisted of questions about the demographics and nutritional awareness of individuals, the Coronavirus-19 Phobia Scale, and the International Physical Activity Questionnaire (short form). Results: The mean total coronaphobia score was 51.08 ± 14.47 with the mean score for women being significantly higher than that for men (p < 0.05). The mean score obtained by the responses of participants to questions about nutritional awareness during the pandemic was significantly higher than the mean score referring to the period before the pandemic. The examination of the physical activity level of employees revealed that 62.4% of the men and 60% of the women were physically inactive during the pandemic. Conclusion: It was found that the coronaphobia scores of municipal employees during the coronavirus disease 2019 pandemic were at an average level, their nutritional awareness levels increased in general compared to the pre-pandemic period, and municipal employees were mostly inactive physically during the pandemic.

The effect of obesity on human reproductive health and foetal life.

Obesity in both women and men is regarded as one of the many factors that may contribute to impaired reproductive health. Obesity can be accompanied by several neuroendocrine and ovarian dysfunctions, including chronic oligo/anovulation, menstrual irregularities, subfertility, and the increased risk of pregnancy in women. Insulin resistance, elevated triglyceride and fatty acid levels, and the secretion of adipocytokines caused by the excessive accumulation of adipose tissue associated with obesity adversely affect reproductive functions. Alterations in sperm quality and motility and hormone levels related to a rise in body mass index (BMI) may predispose men to infertility. The mechanisms of action of obesity on male infertility include endocrinopathy, erectile dysfunction, epididymitis, increased leptin and adipocytes, increased aromatase, inflammatory cytokines secreted by fat tissue, and sperm DNA fragmentation. This study reports that an increased BMI may lead to low semen quality, poor sperm motility, and reduced fertilization rates in men as well as anovulation, pregnancy loss, diminished pregnancy, and low live birth rates in women. Having optimal weight with balanced nutrition enables one to maintain a continuity of reproductive health throughout the entire life cycle, which is extremely important in terms of having a healthy embryo, including pre-foetal life, in the continuity of pregnancy and having a live birth.

Associations between diet quality, DASH and Mediterranean dietary patterns and migraine characteristics.

This study was conducted to describe the dietary patterns and diet quality and to examine the correlation between diet quality, dietary patterns (Mediterranean or DASH) and migraine attributes.Individuals between the ages of 18-64 who applied to the headache outpatient clinic and were diagnosed with episodic migraine were evaluated by a neurologist. Healthy Eating Index-2010 was used to determine the diet quality. Dietary Approaches to Stop Hypertension compliance scale and Mediterranean Diet Adherence Screener were used to describe the dietary patterns.It was found that individuals with a low Mediterranean Diet Adherence Screener score had more severe disability and more severe and frequent attacks (p < 0.05). In addition, a significant negative correlation was found between Mediterranean Diet Adherence Screener score and attack severity (r = -0.733, p < 0.05). Individuals with a low Dietary Approaches to Stop Hypertension compliance scale score had more severe and frequent attacks (p < 0.05). There was a significant negative correlation between attack severity and Dietary Approaches to Stop Hypertension compliance scale scores (r = -0.700, p < 0.001). Individuals with poor diet quality had more severe migraine attacks compared to others (p < 0.05). A significant negative correlation was found between diet quality total score and attack severity (r = 0.458, p < 0.05). High diet quality scores and higher vegetables, fruits, legumes, and oil seeds subscores, DASH and Mediterranean dietary patterns were associated with lower migraine attack severity (p < 0.05).A nutritional approach that adopts the Mediterranean diet or involves a good diet quality pattern can help alleviate the symptoms of individuals with migraine.
