Development of a campus-based intervention program to strengthen food literacy among university students: A qualitative formative study: Eunji Ko, Eunjin Jang, Jiwon Sim, Minjeong Jeong, Sohyun Park; Korean J Community Nutr 2023;28(6):495-508. Published online December 31, 2023; DOI: https://doi.org/10.5720/kjcn.2023.28.6.495

Abstract PDF: Objectives
This study aimed to develop a campus-based intervention program to enhance food literacy (FL) among university students.
Methods
In the initial phase, we conducted a literature review of FL intervention studies and held in-depth interviews with university students to identify facilitators and barriers to improving and practicing FL. Expert counseling sessions were conducted with nutrition education, marketing, and service design professionals. The results of this phase led to the creation of an initial curriculum draft. In the second phase, a follow-up survey was conducted with young adults to assess the acceptability of the developed curriculum. After the follow-up survey, additional meetings were conducted with the aforementioned experts, and the curriculum was further refined based on their input.
Results
An 11-week FL intervention program was devised using constructs from the Social Cognitive Theory. The weekly curriculum consisted of 90-min theory-based and 90-min hands-on experience sessions. Three primary aspects of FL were covered: nutrition and food safety, cultural and relational dimensions, and socio-ecological aspects. Program highlights included cooking sessions for crafting traditional Korean desserts, lectures on animal welfare, insights into zero-waste practices, and communal eating experiences. Based on the study team’s previous research, the program also addressed mindful eating, helping participants understand the relationship with their eating habits, and providing strategies to manage negative emotions without resorting to food. Yoga sessions and local farm visits were incorporated into the curriculum to promote holistic well-being.
Conclusions
This study elucidated the comprehensive process of creating a campus-based curriculum to enhance FL among university students, a group particularly susceptible to problematic eating behaviors and low FL levels. The developed program can serve as a blueprint for adaptation to other campuses seeking to bolster students’ FL.

Development of Korean NOVA Food Classification and Estimation of Ultra-Processed Food Intake Among Adults: Using 2018 Korea National Health and Nutrition Examination Survey: Hae Jin Park, Sohyun Park, Jee Young Kim; Korean J Community Nutr 2022;27(6):455-467. Published online December 31, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.6.455

Objectives
In this study, we suggest a Korean NOVA food classification that can be applied to food consumption among Korean. Based on this suggestion, the nutritional intake of Korean adults from ultra-processed foods (UPFs) was estimated.
Methods
Korean commercial food was categorized based on the NOVA food classification criteria through the Korea Food Code and expert meetings. Then, the nutrient intake status of 6,991 participants in the 2018 National Health and Nutrition Examination Survey was analyzed according to the food processing level. Then, 4,152 adult participants (age 19-65) were divided into quartiles on the basis of their intake of UPFs, and the nutrient intakes from UPFs were compared.
Results
Korean NOVA Food Classification defines with priority Group I (Unprocessed/ Minimally processed foods) and Group II (Processed culinary ingredients) foods based on the food cooking or consumption. Then, Group III (Processed foods) and Group IV (UPFs) are classified according to whether the characteristics of the raw materials used are maintained or whether the food was consumed before the 1970s. Our analysis results showed that most of the calories in the diet were consumed by Group I (52.7%), followed by Group IV (29.3%). After categorization of the adult participants into four groups according to their energy consumption from UPFs, we found that the highest consumption group (Q4) was younger and had higher percentage of men than women. The comparative analysis of the consumption of ultra-processed foods by Korean adults revealed that participants of a younger age and men consumed higher energy from UPFs than older participants and women, respectively (P < 0.01). Furthermore, the larger intake of UPFs was associated with an increasing trend for a higher intake of energy, sugar, saturated fat (P for trend < 0.001), total fat (P for trend = 0.021), and sodium (P for trend = 0.005), whereas the intake of carbohydrate, protein, and dietary fiber had a decreasing trend (P for trend < 0.001).
Conclusions
With the current increase in the consumption of processed and ultra-processed foods, it is important to carefully consider not only nutrient intake but also the level of food processing.

Using Service Design Tools in Community Nutrition Research: A Case Study in Developing Dietary Guidelines for Young Adults: Eunbin Jo, Jae Eun Shim, Hyun Joo Ryou, Kirang Kim, Su Jin Song, Hyun Ja Kim, Jeong Sun Ahn, Kwang-il Kwon, Hye Young Lee, Sohyun Park; Korean J Community Nutr 2022;27(3):177-191. Published online June 30, 2022; DOI: https://doi.org/10.5720/kjcn.2022.27.3.177

Abstract PDF

Objectives
Recent epidemiological data reported that young adults in their 20 ~ 30s are a vulnerable population with unhealthy dietary practices and a few signs of deteriorated health indicators. However, there are no dietary guidelines that are specifically developed for the young adult population. This study introduces some data collection tools that are mostly used in the service design field, and demonstrates how these tools can be used in nutrition research for developing dietary guidelines for specific target groups.
Methods
To understand the context of food choices among young people, 39 people were enrolled to complete a probes booklet. Thematic analysis and word cloud were performed to capture the main themes from the probes and a persona was developed based on the findings.
Results
Data from the probes enabled us to grasp the various contextual meanings of eating practices among young people. Most participants understand what a healthy diet is and often have a willingness to practice it. However, there were very few participants who were following the practices. We created four types of persona for developing dietary guidelines: healthy eating, emotional eating, convenient eating, and trendy eating.
Conclusions
Probes and persona were used in order to understand the lives of young adults and develop targeted messages. We hope that this introduction will be helpful to researchers who are looking for new ways of understanding their target population in the field of community nutrition.

Basic Concepts and Detailed Dimensions of Food Security and Related Indicators for Policy Development and Evaluation: Sohyun Park, Ji-Yun Hwang, Jae Eun Shim, Kirang Kim; Korean J Community Nutr 2021;26(6):429-440. Published online December 31, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.6.429

Abstract PDF: Objectives
Standardized guidelines and reference points for a food security policy are necessary to guarantee that basic social safety nets work properly. Therefore, this study aimed to explore the basic concepts and detailed dimensions of food security, including the potential relevant indicators, and sought to establish standardized well-being baselines.
Methods
A literature review and 14 expert roundtable discussions were carried out to analyze and extract the key concepts of food security. After determining these concepts and detailed dimensions of food security, a conceptual framework was modeled. Then, indicators for each local government that could be monitored and evaluated for each sub-area were suggested.
Results
The concept of food security was defined as follows: Individuals should be provided with sufficient, safe, and quality food, which should be accessible to the community and available for use to achieve health and well-being. In addition, food security should be ensured sustainably in a changing environment. Four dimensions were suggested while conceptualizing food security. First, sufficient food, which means sufficient food supply in quantity, quality, and safety. Second, equitable food which includes creating environments in which high-quality and safe food can be purchased at an appropriate price and can be provided regardless of the socioeconomic gap. Third, healthy food which should be provided to promote people’s health and happiness through the eco-friendly consumption of food. Fourth, sustainable food, which can be supplied in a sustainable manner and as part of an eco-friendly food system that considers the conservation of natural environments.
Conclusions
The basic concepts and detailed areas of food security including the potential indicators proposed in this study, may be useful for developing and implementing various policies and programs to support food and nutrition security in the future.

Defining Food Literacy and Its Application to Nutrition Interventions: A scoping Review: Hye lim Yoo, Eun bin Jo, Kirang Kim, Sohyun Park; Korean J Community Nutr 2021;26(2):77-92. Published online April 30, 2021; DOI: https://doi.org/10.5720/kjcn.2021.26.2.77

Abstract PDF

Objectives
Food literacy (FL) can be an important concept that embodies the nutritional capabilities of individuals. The purpose of this study was to introduce the definition and core elements of FL from previous literature, to summarize measurement tools and intervention programs with FL, and to suggest the direction of future research and programs to integrate the concept of FL. Methods: The literature review was conducted through PubMed and Google Scholar databases by combining the search term ‘food literacy’ with ‘definition’, ‘measurement’, ‘questionnaire’, ‘intervention’, and ‘program’. Among the 94 papers primarily reviewed 31 manuscripts that suited the purpose of the study were used for analyses. Results: There is no consensus on the definition of FL that encompasses the multidimensional aspects of the concept. The definitions of FL were slightly different depending on the authors, and the interpretation of the core elements also varied. Based on the review, we propose a framework of FL that is in line with the current discussion among international researchers. This focuses on the core elements adapted from health literacy, namely functional, interactive, and critical FL. Specifically, we suggest some detailed elements for interactive and critical FL, which were often the subject of divergent views among researchers in previous literature. We found that most of the tools in the reviewed literature provided information on validity and reliability and were developed for a specific target population. Also, most of the tools were focused on functional FL. Similarly, most of the interventions targeted functional FL. Conclusions: This study reviewed the definition and core elements of FL, available measurement tools, and intervention programs using validated tools. We propose the development of tools with sound reliability and validity that encompass the three core elements of FL for different age groups. This will help to understand whether improving food literacy can translate into better nutritional intake and health status among individuals and communities.
