The purpose of this study was to develop a sustainable dietary education program for middle school home economics subject using a teaching strategy to improve the empowerment of adolescents and to verify and evaluate the effectiveness of the program. To achieve the purpose of this study, the program was developed and evaluated according to the ADDIE teaching design model. The contents related to the dietary area were extracted from the technical & home economics curriculum of the 2015 revised middle school and SDGs, and their relevance was analyzed to select the contents of dietary education. The program developed based on the analysis results is 'dietary life together' and consists of five learning topics: 'living together in the global village', 'maintaining healthy diet', 'creating a dietary culture together', 'living with nature and people', and 'maintaining a safe diet'. As a strategy for improving empowerment, we presented four situations, each of which represents value judgment, prediction of results, responsible behavior choice, and decision making. The developed program was reviewed by experts and applied to 17 unit classes for 17 weeks (1 unit hour per week) to the third graders of middle schools in Gyeonggi-do. Significant differences were found between before and after the class measurements of the personal empowerment and the political and social empowerment, which shows the classes were effective in improving empowerment. However, since there was no significant difference in interpersonal empowerment before and after the program, suggestions were made to utilize strategies to facilitate discussion and cooperative learning when implementing the program. The students who participated in the class evaluated the program positively as a whole. The program was evaluated to have helped the students believe they could change society through solving dietary problems.

Objectives: Diet and incidence of chronic diseases are highly related. This study examined the characteristics of dietary safety awareness and competency for chronic disease prevention among adults. Methods: Data were collected from 247 adults in Daegu and Gyeongbuk areas using a self-administered questionnaire in May and June of 2018. Data were analyzed by frequency analysis, χ²-test, factor analysis, reliability analysis, t-test, one-way analysis of variances, and correlation. Results: The results of the factor analysis indicate that dietary safety awareness of health management was classified into chronic disease anxiety and obsession. Awareness of dietary safety management was sub-grouped into difficulty in acquiring knowledge, lack of awareness of over and malnutrition, food safety anxiety, importance of weight management, education requirement for cancer prevention, and knowledge. Dietary safety behavior composed of a balanced diet, unhealthy diet, and health-functional pursuit. Dietary safety management competency was comprised of health management, food management, and cooking. The competency scores of dietary safety management factors were significantly different according to sex, age, and education level (P < 0.05). Balanced diet factor was significantly correlated with knowledge, health-functional pursuit, health management, food management, and cooking capacity factors (P < 0.01). Conclusions: Active education for dietary safety management competency according to age, gender, and education level should provide dietary safety education to reduce anxiety and obsession regarding chronic diseases and sustainable health management.

Globally, agriculture is one of the largest consumers and polluters of water resources, contributing to the unsustainable use of limited water resources. To reduce the resource use and environmental footprints associated with current and future food systems, researchers and policy makers have recommended the transition to sustainable and healthier diets and the reduction of food loss and waste along the food supply chain. However, there is limited information on the synergistic effects and trade-offs of adopting the two measures. In this study, we assessed the water-saving potential of the two measures in South Korea using environmentally extended input-output relying on the EXIOBASE database for the reference year 2020, along with scenario analysis to model the potential outcomes. Specifically, we analyzed scenarios where meat consumption was reduced by 30% and 50% and in combination with a 50% reduction in food waste at the consumption stage for each scenario. According to our findings, by considering individual measures of dietary change and food waste reduction, shifting to a diet with 30% and 50% less meat consumption could lead to reduction in water footprint by 6.9% and 7.5%, respectively, while 50% reduction in food waste at the consumption stage could save about 14% of water footprint. However, the synergistic effects of the two measures such as 30% less meat consumption and 50% food waste reduction, and 50% less meat consumption and 50% food waste reduction result to 20% and 24% reductions in water footprint, respectively. Moreover, our findings also showed that increasing food consumption with high environmental impacts could promote resources use inefficiency when waste occurs. Thus, policy strategies that address synergistic effects of both dietary change and food waste reduction should be strengthened to achieve sustainable food system. International and national policies can increase resource efficiency by utilizing all available reduction potentials while considering strategies interactions.

Purpose: The purpose of the study was to examine the snack meal management for infants and toddlers and the demand for snack products according to mothers' sustainable dietary style in the Jeonbuk area. Methods: The participants were 359 mothers in the Jeonbuk area. The data was analyzed using factor analysis, cluster analysis, analysis of variance, and χ²-tests with SPSS v. 25.0. According to the sustainable dietary style, the situation of providing snacks at home, the purchasing behavior for snack products, and the satisfaction and, demand for snack products were investigated. Results: Using the K-clustering method, the sustainable dietary style of the subjects was categorized into 3 clusters. Cluster 1 was the family health-seeking group, cluster 2 was the sustainable dietary trend group, and cluster 3 was the sustainability-interested group. The frequency of snack intakes according to the cluster groups showed a significant difference (p < 0.001). Fruits were the snack item most frequently consumed by all the cluster groups. Approximately 92.8% of mothers had purchased snack products, and 95.2% of the subjects were satisfied with them (p < 0.05). The main reason for satisfaction with the snack products in all the cluster groups was the various kinds of products with considering the growth stage of children. Clusters 2 and 3 required the development of snack products using organic food materials, while cluster 1 required the snack products to be supplemented with various nutrients. Conclusion: It is necessary to develop various snack products according to the sustainable dietary style and the needs of mothers so that these snacks can increase the satisfaction of mothers with the snack products and lead them to better snack purchasing behavior.

This study was performed to improve the effectiveness of dietary education using a food ethics approach. Dietary education is a way of practicing food ethics based on Korean culture. The core values of dietary education and the keywords related to food ethics can be combined into environment·life, health·wisdom, and consideration·happiness. Sustainable dietary life comprises the value system of dietary education based on core values. To reach the ultimate goal of food ethics-sustaining the survival of the human race, the coexistence of humans and nature, the coexistence of humans and humans, and the fulfillment of food requirements are needed. These needs yield certain core principles, including respect for life, environmental preservation, justice, the priority of consumers, dynamic equilibrium, and the priority of safety. The extended ethical matrix with six core principles and three interest groups can be used for an ethical analysis either qualitative or quantitative. It is believed that if food ethics are introduced into dietary education programs, the effectiveness of education can be improved.

Considering the importance of institutional foodservice in modern dietary life and its influence on the environment, sustainable development in institutional foodservice industry carries great significance. The current study was conducted to investigate dietitians' perceptions of sustainable business-and-industry foodservice and their intentions to perform sustainable practices by applying a mixed methodology. For the quantitative study, an online survey was conducted on 362 dietitians who had worked at a contact foodservice company for more than 1 year. The survey was performed from December 15th, 2011 to January 30th, 2012, and 202 responses were used for the analysis. For the qualitative a study, a focus group interview was conducted during May, 2012 with representative employees of the company. According to the results, dietitians seemed to be unfamiliar with the terms "sustainability" or "sustainable development," whereas they understood related contents and practices. Dietitians' awareness and perceived need in terms of sustainable business-and-industry foodservice were not significantly different across general characteristics. Dietitians seemed to be highly aware of the impacts of business-and-industry foodservice on economy, whereas they appeared to lack understanding of its impacts on society and environment. Cost increase and levy on work in daily operations were considered as main obstacles hampering dietitians' intentions to perform sustainable practices. A total of 88.1% of responding dietitians expected that the meal price at a sustainable business-and-industry foodservice should be higher than the supposed standard price of 4,000 won, with an average reaching 5,270 won. Findings from this study could be used as baseline information for vitalizing sustainable business-and-industry foodservice in Korea.

The sufficient amount of protein supply is crucial for improving the growth performance of growing beef cattle. In addition, due to the improvement in the genetic potential of the carcass weight of Hanwoo steers, dietary protein requirements may be increased during the rapid growth period. Accordingly, the dietary crude protein (CP) level in growing Hanwoo steers has been increasing in the field. However, little scientific evidence is available in relation to this. Therefore, this study was conducted to test whether a higher dietary CP level than convention would improve the growth performance and body metabolism in growing Hanwoo steers. Fifty growing Hanwoo steers were randomly divided into two groups and fed either a commercial diet (CON) or a higher CP (HCP) concentrate mix, provided with a similar level of dietary energy. Tall fescue hay was provided ad libitum. The dietary CP level did not affect growth performance and blood metabolite. Nitrogen intake, predicted nitrogen excretion, and retained nitrogen were higher in the HCP group than in the CON group (p < 0.01). Although there was no difference in the nitrogen utilization efficiency, the growth efficiency per retained nitrogen decreased in the HCP group (p = 0.02). A higher dietary CP level may increase nitrogen retention in growing Hanwoo steers without improving growth performance, which leads to reduced growth efficiency per retained nitrogen. Furthermore, considering the high price of feed protein and increased nitrogen excretion to the environment, a further increase in the protein level may not be sustainable.

Purpose: Obesity can lead to several chronic diseases. With a continuous increase in the obesity rates, sustainable healthy weight management among growing adolescents has become essential. This study was conducted to examine the relationship between obesity-related factors and creative convergence ability. This could form the basis for convergence education for the sustainable healthy weight management of adolescents. Methods: Data were collected from 430 adolescents in Daegu, Gyeongbuk, and Gyeonggi regions using a self-administered 5-Likert questionnaire from November to December 2020. Results: The average score of the male students was higher than that of the female students in terms of healthy weight management convergence awareness, creativity, convergence thinking ability, self-efficacy, exercise, and dietary diversity. On the other hand, the dietary restraint score and the number of weight loss attempts were higher in the female students. Dietary restraint, disinhibition scores and weight loss attempts were higher in obese adolescents compared to underweight adolescents. It was found that dietary restraint, convergence thinking ability, problem-solving ability, exercise, and dietary diversity factors had a positive effect on healthy weight management convergence awareness. Healthy weight management convergence awareness, exercise, meal amount management, junk food management, weight loss belief, and weight loss trial experience had a positive effect on dietary restraint. Convergence thinking ability, weight loss experience, and obesity factors had a positive effect on dietary disinhibition. Conclusion: The sustainable healthy weight management education of adolescents is based on weight management knowledge and awareness of convergence, and must include gender differences. Thus, the problem-solving ability for healthy weight management can be creatively cultivated to enhance self-efficacy.

Two dietary experiments were performed to evaluate the impact of the herb Mentha piperita as a dietary supplement on Catla catla. In Experiment 1, fingerlings (0.45-2.60 g) were fed on diets supplemented with M. piperita at different levels (P1, P2, P3, and P4 at 2, 4, 6, and $8g\;Kg^{-1}$ of feed) and C1 served as the control with no peppermint supplementation. In Experiment 2, fingerlings (0.40-3.15 g) were fed with diets containing autochthonous probiotic bacteria Bacillus coagulans (3000 colony forming unit $g^{-1}$) along with M. piperita (PP1-PP4 at 2, 4, 6, and $8g\;Kg^{-1}$ of feed) and feed C2 served as control containing probiotics but no peppermint. Significantly (P < 0.05) high values of growth parameters, digestive enzyme activities, low reed conservation ratio, low excretion of ammonia, and orthophosphates were observed in fingerlings fed with P3 for Experiment 1 and PP3 for Experiment 2. Hematological counts, phagocytic activity, and respiratory burst activity were also enhanced in fingerlings fed with M. piperita supplementation revealing that dietary administration of peppermint at optimum level can enhance the growth, digestibility, and immunity of C. catla fingerlings; however, incorporation of B. coagulans showed better growth and immunity revealing that synergistic effects of M. piperita and autochthonous probiotic in C. catla diets can lead to its sustainable aquaculture.

In Korea, several national cross-sectional surveys monitor the diet, nutritional status, and health status of children. This continual dedicated national surveillance system contributes to the identification of nutritional and health issues, establishment of public health policies, and development of nutrition recommendations. This paper provides recent information about the Korea National Health and Nutrition Examination Survey and the Korean Youth Risk Behavior Web-based Survey and describes key nationwide survey findings published in the last 5 years on infant feeding practices and the dietary intake and nutritional status of Korean infants, children, and adolescents. There have been increasing trends in children, and teenagers who skip breakfast, eat fast food, consume sugary drinks, have vitamin D deficiency, and are obese. This review will inform pediatricians, nutritionists, and other health care practitioners who track children's growth and development. It may also help researchers and policymakers identify diet-related policies and strategies for chronic disease prevention in Korean infants, children, and adolescents.
