Background: Time-restricted eating (TRE) is a current popular dietary strategy for noncommunicable diseases. However, studies demonstrated contradictory results for it and in all dietary strategies, diet quality is an the important part of the well-being. Our study aimed to investigate the effect of TRE and energy-restricted diet (ERD) on the nutritional status and diet quality of individuals. Methods: This pilot study was completed 23 healthy overweight female. Anthropometric and body composition measurements of individuals were taken. The energy expenditure was measured using indirect calorimetry. Blood pressure and heart rate measurements were made. Biochemical parameters were evaluated and food consumption were taken. The quality of dietary intake was assessed using the Healthy Eating Index (HEI) -2015. The physical activity levels of the individuals were estimated using the physical activity record. The Statistical Package for the Social Sciences (version 22.0) software was used for all analyses. A p-value of less than 0.05 was considered to be statistically significant. Results: After 8 weeks of intervention, while no change was observed in the diet quality of the individuals in the TRE group (p > 0.05), a significant increase was found in the diet quality score of the individuals in the ERD group (p < 0.05). There was a 3.2% and 5.5% decrease in body weight of individuals in the TRE and ERD groups, respectively (p < 0.05). While no significant change was observed in the body fat percentage of individuals in the TRE group (p > 0.05), a 7.1% decrease was observed in the ERD group (p < 0.05). A statistically significant decrease was found in the total cholesterol (3.7%) in the ERD group, and in the total cholesterol (6.7%) and low density lipoprotein cholesterol (LDL-C) (6.5%) in the TRE group. In addition, a statistically significant increase was found in adiponectin (77.3%) and total antioxidant status (TAS) (13.2%) in the ERD group. Conclusion: Energy-restricted diet yielded better results in weight loss and improvement of body composition and diet quality compared to TRE. Also, a decrease in total cholesterol level was found in the ERD group. However, more studies should be done with longer follow-ups and high sample sizes are very important in terms of creating public health-based recommendations.

Objective: The determination of nutritional knowledge and nutrition literacy among nursing students will enable nursing departments to establish the needs and solutions to enhance nutrition education in their education programs. Therefore, this study is aimed to evaluate the nutrition literacy and nutrition knowledge level of nursing students.Method: The study data were collected with ‘Information Form’, ‘Anthropometric Measurements’, ‘Nutrition Knowledge Level Scale for Adults’, and ‘Evaluation Instrument of Nutrition Literacy on Adults’. Analyzes were performed using descriptive and nonparametric tests.Results: The score of nutrition knowledge is 56.6 ± 6.8 and 50.5% of them have a good nutrition knowledge level. The total nutrition literacy score is 28.6 ± 4.4 and 91.6% of them have a sufficient nutrition literacy level. It was no significant difference between students’ characteristic features and nutrition knowledge score and nutrition literacy total score (p > 0.05). There was a statistically significant positive correlation between the nutrition knowledge score and the nutrition literacy total score and the nutrition literacy sub-sections scores (p < 0.05).Conclusion: It has been determined that the nutrition knowledge and nutrition literacy levels of nursing students correlated with each other. To improve students’ nutrition knowledge levels, as well as to improve their nutrition literacy and prevent non-communicable diseases nutrition lessons should be included in the curriculum.

The aim of this study is to investigate the relationship between food and cooking skills and healthy eating attitudes in college students. The demographic characteristics, anthropometric measurements, nutritional habits, attitudes toward healthy eating, and cooking and food preparation skills were questioned. 16.2% of the students have moderate, 63.5% high, and 20.3% ideally high attitudes toward healthy eating. While a positive and significant correlation was found between the total score and sub‐factor scores of the “Cooking Skills and Food Skills” scale and the total score of the “Attitude Scale for Healthy Nutrition”; a negative statistically significant correlation was found between the total score and sub‐factor scores of the “Cooking Skills and Food Skills” scale and the frequency of consumption of fast‐food, processed meat products, packaged foods, and bread types (p < .05). Cooking and food preparation skills seem to be positively associated with healthy attitudes and habits. Considering this positive association, interventions to improve food and cooking skills may help promote healthy eating attitudes in college students. Developing these skills can shed light on increasing the frequency of cooking at home, consuming healthier foods, and as a result, providing a healthy eating attitude. Therefore, more comprehensive intervention studies are needed in this area.

Industrialization and urbanization increase the consumption of ultra-processed foods (UPFs); decreasing cooking skills and low food literacy make healthy eating difficult. The aim of this study is to evaluate the effects of individuals’ cooking and preparation skills and food literacy levels in relation to UPF consumption and to contribute to strategies that will promote healthy eating. This cross-sectional study included 3572 adults (2413 females, 1159 males) aged 18–65 years selected through snowball sampling in Ankara, Türkiye. Data were collected via a web-based survey including demographic information, self-reported anthropometric measurements, and validated scales: The High Processed Food Consumption Screening Questionnaire (with higher scores indicating greater consumption of UPFs), the Cooking and Food Preparation Skills Scale (where higher scores indicate better cooking and food preparation skills), and the Food Literacy Tool (with higher scores reflecting higher levels of food literacy). The Screening Questionnaire of Highly Processed Food Consumption score was negatively correlated with the total and subdimension scores of the Cooking and Food Preparation Skills Scale, as well as with the total score of the Food Literacy Tool. (p < 0.001). According to the linear regression analysis, gender, age, the total score of the Cooking and Food Preparation Skills Scale, and the total score of the Food Literacy Tool were significant predictors of UPF consumption (p < 0.05). Significant differences were observed between individuals with low and high levels of UPF consumption in terms of age, gender, marital status, total score on the Cooking and Food Preparation Skills Scale, and total score on the Food Literacy Tool (p < 0.05). In conclusion, given the significant associations of cooking and food preparation skills and food literacy factors with UPF consumption, public health interventions targeting healthy eating habits, improving culinary skills, and increasing awareness of food processing and nutritional quality should be developed. Furthermore, more research is needed in this area to reduce UPF consumption and improve overall diet quality.

Ultra‐processed foods (UPF) play a central role in modern diets but pose a serious threat to public health. The aim of this study was to investigate the relationship between UPF consumption and hedonic hunger, food addiction, and mood and to explain the impact of these factors on dietary habits. This cross‐sectional study included 3997 adults (2517 female, 1480 male), aged 18–65 years, recruited through snowball sampling in Ankara, Turkey. Data were collected via a web‐based survey that included demographic information, self‐reported anthropometric measurements, and validated scales: Screening Questionnaire of Highly Processed Food Consumption, The Power of Food Scale, Yale Food Addiction Scale, and Depression Anxiety Stress Scale‐21. The mean age of the participants was 31.7 ± 12.82 years. The Screening Questionnaire of Highly Processed Food Consumption was positively correlated with the Yale Food Addiction Scale score and the subdimension scores of the Depression Anxiety Stress Scale‐21 (p < 0.05). According to linear regression analysis, it was determined that gender, age, Yale Food Addiction Scale score, and the scores of depression, anxiety, and stress affected the Screening Questionnaire of Highly Processed Food Consumption score (p < 0.05). There was a difference between the groups with low and high levels of UPF consumption in terms of age, gender, marital and working status, Yale Food Addiction Scale score, and the subdimension scores of the Depression Anxiety Stress Scale‐21 (p < 0.05). In conclusion, considering the influence of food addiction and mood on UPF consumption, policies and interventions targeting the psychosocial processes of individuals should be developed and further research conducted in this area to limit the UPF consumption and promote healthy eating habits along with conscious eating behaviors.
