Since the enactment of the School Meal Support Act in 2009, South Korean dietary education has been evolving, placing health, environment, and consideration as its core values. The 3rd Basic Plan for Dietary Education (2020-2024) aims to achieve a sustainable dietary lifestyle that civic agriculture for collective consumption, healthy citizens, and an inclusive society. However, the digital civilization of the Fourth Industrial Revolution is significantly impacting dietary education in schools. Therefore, this study examines sustainable dietary education content in South Korean school meals, diagnoses the phenomena of dietary education facing digital transformation in education due to the Fourth Industrial Revolution, and explores directions for inclusive dietary education through concrete structures and content systems for inclusive dietary education that foster sustainable dietary capabilities. To achieve inclusive dietary education, a structure and system that allow cognitive, normative, and practical learning to be combined in an inclusive way is required. Furthermore, to practice sustainable dietary education, alternative approaches that emphasize the development of learners' core competencies are necessary in the direction of inclusive dietary education that fosters inclusivity.

BACKGROUND/OBJECTIVES: The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. SUBJECTS/METHODS: We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. RESULTS: Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products. Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements. This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. CONCLUSION: This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.

Objectives: This study aimed to assess the adherence to dietary guidelines among college students in the post-COVID-19 era and examine the changes in their dietary habits as the learning environment transitioned from remote to in-person classes. Methods: We conducted a survey involving 327 college students in Daejeon from March to April 2023. The survey questionnaires included various factors, including age, gender, type of residence, frequency of use of delivery food, convenience food, and eating out. In addition, we investigated the extent of adherence to the dietary guidelines for Koreans and the degree of dietary changes following the post-COVID-19 shift in class format were investigated. For comparative analysis of the level of adherence to dietary guidelines in relation to dietary habit changes, an ANOVA and a post hoc Scheffe test were employed. We also performed a multiple linear regression analysis to identify dietary factors influencing the level of adherence to dietary guidelines. Results: The study revealed a high rate of convenience food consumption and a low rate of homemade food intake among students. There was a marked increase in the consumption of processed foods, convenience foods, dining out, sweet foods, high-fat fried foods, beverages, and alcohol following the transition from online to in-person classes. When examining adherence to Korean dietary guidelines, the highest scored practice was 'Hydration', and the lowest was 'Breakfast habit'. Increased consumption of convenience foods, late-night snacks, and dining out were negatively correlated with adherence levels to dietary guidelines, specifically correlating with 'Healthy weight', 'Hydration', 'Breakfast habit', and the total score of adherence. The adoption of 'regular meals' was positively associated with increased adherence levels to dietary guidelines. Conclusions: The transition from remote to in-person classes post-COVID-19 led to increased intake of convenience foods, dining out, sweet foods, high-fat fried foods, and alcohol. The rise in convenience food and late-night snack consumption negatively influenced several aspects of the dietary guidelines adherence, thereby suggesting the need for strategies to encourage healthy dietary habits among college students.

The dietary fiber contents of soybean sprout and spinach were changed by heat treatment. Before heat treatment, soybean sprout and spinach had larger amount of insoluble dietary fiber than soluble, and similar proportions of insoluble v/s soluble dietary fibers. After heat treatment, the value of insoluble dietary fiber of soybean sprout and spinach was increased significantly, except for microwave heating short time treatment. It is believed that the increment of insoluble dietary fiber is due to Maillard reaction products and resistant starch after heat treatment. The change of soluble dietary fiber contents of soybean sprout and spinach were not consistent in heat treatment. It is supposed that some soluble dietary fiber was destroyed by heat treatment, and some insoluble dietary fiber was hydrolysed or destroyed to be soluble. Total dietary fiber of soybean sprout and spinach was significantly incereased by all heat treatment, except for microwave heating short time of spinach.

Effects of a short-period nutrition education program on the dietary behavior and the dietary intake were investigated in sixty nine healthy female college students. Questionnaires for general health information, character type, dietary behavior and dietary intake were answered by the subjects. All the subjects were participated in the nutrition education program which was carried out twice during the study. Subjects were divided into three groups according to their adiposity indices (AI), which are low AI (33 subjects), normal AI (31), and high AI (5). In the normal and the high AI group, the nutrition education program appeared to influence the dietary behaviors of the subjects significantly. However the program did not significantly influence the dietary intake of three groups, except PUFA ratio. It appears that a longer-period nutrition education program is required for influencing both the dietary behavior and the dietary intake of the subjects.

Bacterial transformation of bile acids is possibly involved in colorectal carcinogenesis. n several epidemiological studies, the fecal bile acid dietary fiber are related to the indicence of colonic cancer. This study investigated the influence of age, dietary fiber intake on fecal bile acid profiles in healthy subject. The dietary fiber were assessed by mean of 24 hour dietary recall method, the subjects consist of 238 members aged 20 to 64 years old and feces are collected from the subjects. Fecal bile acids and neutral sterols were analyzed by gas chromatography. Mean dily crude fiber intake level was 7.7$\pm$1.4g(dietary fiber : 16.7$\pm$3.5g), dietary fiber intake range being 6.5-36.8g. The dietary fiber intake in elederly subject was significantly lower than in the other younger groups. Dietary fiber intakes was negatively correlated with the total bil acid concentation in feces. Probably, a decrease in dietary fiber intake results in higher fecal bile acid concentrations. The secondary bile acid concentration is related to the colon cancer, deoxycholic acid and lithocholic acid were significantly higher in elderly subjects. Concentration of fecal total bile acid, deoxycholic acid, coprostanol, coprostanone were higher in low dietary fiber intake group. These results suggest that the risk factor for colon cancer might be reduced, when dietary fibers are consummed more.

Purpose: The purpose of this descriptive study was to identify gender differences in predictors on dietary self-efficacy in fifth and sixth grade elementary school children. Methods: The data were collected by a questionnaire given to the 408 children between June 7 to June 17, 2011. Descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression were used to analyze the data. Results: There were gender differences in dietary self-efficacy, exercise self-efficacy, dietary practice and depression. Dietary self-efficacy had a significant positive correlation with exercise self-efficacy and dietary practice and negative correlation with depression for both girls and boys. The predictors of dietary self-efficacy for boy were exercise self-efficacy and dietary practice, these factors explained 37.1% of the total variance. In girls, exercise self-efficacy and dietary practice were significant predictors and explained 38.7% of dietary self-efficacy. Conclusion: Based on the finding of this study, it is needed to develop a nursing intervention for dietary self-efficacy in elementary school children including to promote exercise self-efficacy and dietary practice.

This study was performed to examine dietary habits, nutrition knowledge and dietary behaviors of elementary school students by sex and skipping breakfast. The subjects were 3rd grade elementary school students in Ulsan area (total 1,349; 734 males and 615 females). The skipping breakfast group were 215 students, 15.4% of total subjects. Major reasons for skipping breakfast were 'have no time' 27.8%, 'no appetite' 26.9%, 'over sleeping' 14.9%. Females and eating breakfast group had better dietary habits than males and skipping breakfast group. The scores of nutrition knowledge of females were higher than those of males. The dietary behaviors scores of eating breakfast group were higher than those of skipping the breakfast categories. Our results showed that these difference by sex and skipping breakfast in dietary habits, nutrition knowledges, dietary behaviors should be considered in developing of nutrition education program for low-grade elementary school students.

This study examined the nutritional status and dietary behaviors of university students in Gangwon-do as well as the effects of dietary education on them. Forty college students were recruited, and their dietary lifestyle was examined using an Adult NQ questionnaire before and after dietary education. The questionnaire items were grouped into four categories: balance, diversity, moderation, and dietary behavior. The mean NQ score out of 100 was 48.00. Among the three grades of the NQ grade criteria, most subjects (50%) were in the lowest grade, which was poor. The mean scores of the NQ factors were highest for moderation (68.76%), followed in order by diversity (50.81%), dietary behavior (45.66%), and balance (21.01%). Compared to the criterion value, moderation was only good, and balance was the worst. These results suggest that the nutritional status of the subjects is poor. On the other hand, there was a significant change in the areas of the NQ score (53.7), balance (29.22) and dietary behavior (56.77) after dietary education. Nevertheless, the 'balance' area remained lower than the average, highlighting the need for education on food intake to enable diverse food intake.

Purpose: The study was to test the effects of nutrition education program changing the dietary self-efficacy and dietary practice of elementary school children. Method: The study was designed as a nonequivalent control group pretest-posttest design. The subjects of the study were 70 boys and girls in the fourth grade of elementary school in Seoul. They were devided in two groups evenly : control group and treatment group. The control group participated in the nutrition education with 4 sessions for 4 weeks. data were collected by self-reported questionnaires(dietary self-efficacy and dietary practice) from the 28th of August to the 10th of October. 200l. Result: 1. A hypothesis that 'the elementary school children who participated in the nutrition education may get higher points on dietary self-efficacy than the elementary school children who did not participated' has been adopted(t=-6.36. p<001). 2. A hypothesis that 'the elementary school children who participated in the nutrition education may get higher points on dietary practice than the elementary school children who did not participated' has been adopted(t=-5.03. p<001). Conclusion: The nutrition education is an effective nursing intervention strategy for elementary school children by supporting them form positive dietary self-efficacy and improve dietary practice.
