        There has been an increase in the viewing of YouTube content among children and adolescents. This, coupled with the popularity of live-streamed video content such as mukbang, where viewers watch the host eat, has raised concerns about media addiction and the indiscriminate imitation of eating behavior. Therefore, there is a need for guidance on the appropriate behavior for viewing YouTube food content to promote healthy eating habits among children. In this study, we aimed to compare the patterns of the main caregivers and their children while viewing media and investigate the impact of viewing YouTube food content on the physical and mental health of the children. The findings suggest that active YouTube food content viewing by the main caregivers may reduce imitative behaviors due to passive media consumption by their children. This study provides valuable insights by comparing and analyzing the YouTube content viewing of the main caregivers and their children. The results can be used as a basis for the development of lifestyle-centered guidelines for children. However, it is important to note that this study was conducted during the coronavirus disease (COVID-19) pandemic when there was a significant increase in the use of media, which is limitation of the study.

        The endothelium, a continuous monolayer of cells that surrounds blood vessels, has a variety of physiological roles. Chronic exposure to psychological and physical stress, oxidative stress, and inflammation activates the endothelial signaling cascade, resulting in vascular dysfunction such as vasospasm, thrombosis, and abnormal vascular proliferation. Aging is also a significant factor in vascular dysfunction, mainly developing structural and functional changes in the endothelium. The molecules involved in endothelial dysfunction are typically angiopoietin-1 (Ang-1), Tie2, and tight junction proteins. Ang-1, an oligomeric-secreted glycoprotein, is required for the correct organization and maturation of newly-formed vessels. Ang-1 binding to tyrosine kinase receptors Tie-2 leads to the phosphorylation and activation of multiple signaling pathways related to vascular permeability. Endothelial junctions are another vital target of Tie-2 activation. Nutrition and food are closely connected with vascular dysfunction and permeability. The caloric restriction prevents age-related declines in endothelial function. Dietary patterns that prioritize moderate intake of fruits and vegetables, whole grains, low-fat dairy products, and lean meats improve endothelial function in the elderly. Natural products such as Centella asiatica, Pueraria montana, and Piper retrofractum have also been shown to help inhibit endothelial dysfunction. This review provides an update on aging-related vascular dysfunction and the role of food and nutrition.

        Unhealthy dietary behavior such as insufficient calcium intake can be one of risk factors of osteoporosis and chronic diseases in older people. This study evaluated the recent trends in dietary calcium intake and the food source in Korean adults aged 50 years or older using the Korea National Health and Nutrition Examination Survey (KNHANES, 2015-2019) data. This study used 24-hour recall survey data to investigate the calcium intake, the major food groups and main dishes contributing to the calcium intake. The mean calcium intake was 479.55-506.81 mg/day. The major food groups that contribute to calcium intake were vegetables, milks and fishes. Dairy and frozen desserts and kimchi were the major dish groups that contributed to the calcium intake. Calcium intake from milk in dairy and frozen dessert group has been high in last 5 years (50-64 years old: 34.71-47.68 mg, 65-74 years old: 29.72-43.65 mg, over 75 years old: 22.91-42.93 mg). In addition, baechu-kimchi is the most contributed to the calcium intake in kimchi group (50-64 years old: 35.10-41.47 mg, 65-74 years old: 29.62-34.96 mg, over 75 years old: 23.79-29.13 mg). In conclusion, various source of calcium needs to be recommended to increase intake calcium in over 50 years, which may reduce chronic diseases and improve quality of life.

        The intake of processed foods containing high levels of sugar increases the incidence of chronic diseases, including obesity, diabetes, and metabolic syndrome. Limiting sugar intake is important for a healthy life at all ages. Therefore, this study analyzed food sources and sugar intake by the different age groups based on the 7th Korea National Health and Nutrition Examination Survey (KNHANES). We used 24-hour recall survey data to investigate the daily sugar intake and the major food groups and main dishes contributing to sugar intake. The mean sugar intake was 58.9-66.8 g/day. The three major food groups contributing to sugar intake were fruits (15.2-19.9 g/day), beverages (10.7-12.4 g/day), and milk and milk products (7.6-7.8 g/day). Teas and other non-alcoholic beverages (14.7-17.3 g/day), fruits (12.5-16.2 g/day), and dairy products (7.0-7.6 g/day) were the major food groups that contributed to the sugar intake. Carbonated drinks, apples, and milk were the top sources of sugar intake in each group. In conclusion, the sugar intake of Koreans is mainly from carbonated drinks, fruits, and milk. These results provided the basic data for nutrition education and nutrition program development according to the different age groups of the Korean population.

        This study was conducted to examine the status of food consumption and nutrition intake of young adults according to food security using data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2008~2018). A total of 10,655 young adults aged 19~34 years participated in the study. The subjects in the moderately/severely food insecure group consumed less fruits, vegetables, meat, nuts and seeds than those in food secure/mildly food insecure group after adjusting for confounding factors. The moderately/severely food insecure group significantly decreased mean adequacy ratio (MAR) and nutrient adequacy ratio (NAR) for protein, vitamin A, riboflavin, niacin, vitamin C, calcium, phosphorus and iron compared to the food secure/ mildly food insecure group. The percentages of the participants consuming a daily diet with carbohydrate, protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, phosphorus and iron less than the estimated average requirement (EAR) increased in the moderately/severely food insecure group compared with the food secure group. This study suggested that the nutrition intake of young adults was related to food security status. These findings can be used as basic data for developing nutritional policies for young adults.

        This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

        In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

        In this study, 594 questionnaires administered to men and women residing in the capital metropolitan area who work night shifts were analyzed in order to study the effect of health information cognition on healing needs in accordance with the type of food selection criteria of the night worker. The results of confirmatory factor analysis in deriving food selection type identified four categories, a safety seeking type, a food exploratory type, a habitual seeking type, and a rational type, and the cognition types on health information were classified into physical cognition and psychological cognition. The need for healing, which was the investigated factor, was found to have a high correlation between questionnaire items with high reliable consistency. The results of this study were as follows. First, the food selection types of safety seeking type and habitual food seeking type had significant positive effects on the cognitive level of physical health information, and food exploratory type and habitual seeking type had significant positive effects on the cognitive level of psychological health information. In addition, it was shown that food exploratory type and rational type had significant positive effects on healing needs. As a result of this study, it was found that the cognition level of physical and psychological information was different according to food selection type, and the higher the cognitive level, the higher the healing needs. In particular, the result that the level of psychological health information significantly affected healing needs signifies that there is a demand to develop programs and menus that satisfy various needs related to healing and recovery from fatigue. In addition, further interest and study on the health and healing of night workers are required.

        The objective of this study was to analyze labeling improvements and evaluate willingness to pay for health functional foods with a focus on the caution for intake. For this study, we conducted a survey on health functional food intake behavior, confirmation and improvements of cautions for intake. We assessed the willingness to pay for improvement of the caution for intake. Consumers anticipate improved immune function, and fatigue improvement after consumption of health functional foods. They mainly checked the function components related to efficacy and effectiveness, ingredients and their contents, ingestion amount and method, expiry date and best mode of storage, product name, and cautions associated with ingestion of health functional foods. They has been difficulties in obtaining sufficient caution information for intake from the current labeling method. Therefore, it is necessary to improve the labeling of caution for intake. The analysis indicated that about 5.14% of the respondents were willing to pay more if new labeling was introduces. However, there is still controversy over their safety, which is damaging to the consumers. Therefore, by providing consumers with accurate and detailed information on cautions for intake, it can contribute to securing safety and improving the quality of health functional foods.

        This study examined the effects of ‘Dietary education for children’s health UP’ (DECHUP) on the changes in knowledge, attitudes, and practice (KAP) of nutrition and food safety in 5th grade elementary school students in Incheon. The DECHUP program was conducted from May to October 2018 and consisted of education and activities focusing on the children’s levels of understanding. Data were collected before, immediately after, and 6 weeks after DECHUP using the same method. All data were analyzed using SPSS ver 20.0. The level of knowledge and attitudes of the subjects to nutrition and food safety was significantly higher after than before DECHUP, but the attitude of boys did not show any significant difference after 6 weeks. Although there were no significant differences in the behavior for nutrition in the practice of the subjects, there were significant positive changes in the behavior of food safety. The higher the satisfaction of DECHUP, the more positive the change in knowledge, and the more positive the attitude and practice behaviors. Therefore, DECHUP has positive effects on the KAP of the subjects, and it will be helpful for elementary school students to form desirable eating habits if it can be carried out periodically and continuously.

        Introduction Despite the rise of digital media, TV remains the number one place children spend their media time (Moses, 2014). Past research has shown that less healthy food and beverages such as those containing high fat, sugar, and salt (HFSS) are prominent in TV commercials (e.g., Carter, Patterson, Donovan, Ewing, & Roberts, 2011). In these commercials, various persuasive techniques (e.g., taste/smell, convenience), which promote the purchase of the products, have been used (Hebden, King, & Kelly, 2011). Extensive studies have found that exposure to advertising for HFSS products, including confectionery, soft drinks, crisps or savory snacks, fast food, pre-sugared breakfast cereals, is associated with children‟s cognition, food consumption, and obesity (e.g., Harris, Bargh, & Brownell, 2009; Macklin, 1994; see also Moore, Wilkie, & Desrochers, 2017). Since younger children, especially those in the “perceptual stage” of development, may not understand the persuasive or selling intent of commercials (e.g., John, 1999), they may be vulnerable to this advertising. As a result, several countries such as UK and Ireland (Hawkes, Lobstein, & For the Polmark Consortium, 2011) have introduced restrictions or regulations for broadcasting food and beverage commercials for children. The commercials of HFSS food and beverage have sometimes introduced these products with healthier images and words / phrases like health and nutrition claims. Health claims refer to any representation that states, suggests, or implies that a relationship exists between a food (/beverage) or a constituent of that food (/beverage) and health. Nutrition claims mean any representation which states, suggests or implies that a food (/beverage) has particular nutritional properties including but not limited to the energy value and to the content of protein, fat and carbohydrates, as well as the content of vitamins and minerals (Food and Agriculture Organization of the United States & World Health Organization, 2013). Using health messages for HFSS food presents the risk of a biased image of the products (i.e., they are „healthy‟), which may result in unhealthy life styles and conditions. In recent years, there has been regulatory pressure on food advertisers to market their products responsibly (e.g., WHO regulations; Kraak et al., 2016). At the same time, the Children‟s Food and Beverage Advertising Initiative (CFBAI) emerged, in which several leading companies pledged to market their products to children responsibly (see editorial by Boyland & Harris, 2017). Therefore, we were interested in seeing if food and beverage advertising had changed in 2017. Specifically, the purpose of this study was to examine the relative frequency of food and beverage commercials targeting children with a focus on healthy aspects of the products, their health and nutrition claims, as well as other persuasive techniques. Method A total of twenty hours of programming targeting children was recorded on Nickelodeon and Cartoon Networks in the United States during the hours of 5 p.m. to 10 p.m. on two weekdays in September 2017. The advertisements were coded for product type (“food”, “beverage”, fast-food restaurant (“Restaurant: Quick-service/fast food restaurant”), and sit-down restaurant (“Restaurant: Sit-down restaurant”), food type (e.g., “confectionary”, “savory snacks”, “pre-prepared convenience foods”, “bread”, “fruits”, and “vegetables”) (Food and Agriculture Organization of the United Nations & World Health Organization, 2016; Suzuki, 2018), and persuasive techniques (e.g., “health claims”, “nutrition claims”, “taste/smell/flavor”, “convenience”, “scientific information”, “celebrities/a well-known person”, and “eating /drinking behavior”) (e.g., Hebden et. al., 2011; Jenkin, Madhvani, Signal & Bowers, 2014; Kraak & Story, 2015; Warren, Wicks, Wicks, Fosu, & Chung, 2008). Food type can be classified into two categories; Less healthy (“confectionary”, “savory snacks”, “sweet bakery wares”, “other sweets/desserts”, “Sugared breakfast cereals”, “pre-prepared convenience foods”) or healthier categories related to other food categories (Ofcom, 2004; Nutrition Australia, 2013; Suzuki, 2018). Seven coders independently evaluated the advertisements, with two coders assigned to every programming block. They were trained for about three weeks to read the coding manual, practice coding and discuss the coding scheme, and revise their coding after receiving feedback of the trial coding. To check coding reliability, two independent coders evaluated the same programs. 94.3% agreement was achieved for product type. Results and discussion A total of 856 commercials appeared. Food and beverage advertisements represented 29.0% (N=248). On average, children were exposed to 12.4 food and beverage advertisements per hour. Of all the food, beverage and restaurant advertisements, “food” and fast-food commercials were frequently broadcasted; 40.7% (N=101) were for “food” commercials, and fast-food restaurant commercials accounted for 43.5% (N=108). 12.1% (N=30) “beverage” commercials and 3.6% (N=9) sit-down restaurant commercials were included. Food, beverage and restaurant commercials were more likely to appear on Nickelodeon (36.2%, N=129) than on the Cartoon network (28.4%, N=419) (χ2=5.43, df=1, p<.05). As for the appearances of product type, “food” advertisements frequently appeared on Nickelodeon (54.6%, N=65), whereas the programs of Cartoon network included a lot of fast food commercials (61.2%, N=79). In examining the appearances of “beverage”, “food”, “fast food”, and “others (except food, beverage, and restaurant)” between the channels, the results showed that the programs of Cartoon network were more likely to broadcast “fast food” commercials than those of Nickelodeon, whereas the programs of Nickelodeon were more likely to broadcast “food” commercials (χ2=38.23, df=3, p<.01)1. The majority of food types were “confectionary” (25.7%, N=26), “savory snacks” (16.8%, N=17), “breakfast cereals” (14.9%, N=15), and “pre-prepared convenience foods” (13.9%, N=14). In classifying various kinds of foods into two big categories related to health (healthier or less healthy) as above-mentioned, less healthy food accounted for 88.1% (N=89). No commercials were categorized into three of the healthier categories (bread, fruits, and vegetables). As persuasive techniques for consumers, “health claims”, and “nutrition claims” were low (8.9%). For example, grape juice produced by Welch‟s used the appeal “sugar free”. In the commercials with nutrition claims, there was no significant difference in the appearance between the “beverage” and “food” commercials (χ2=1.70, df=1, n.s.). The other persuasive techniques like “convenience” (75.8%, N=188), “taste/smell/flavor” (51.2%, N=127), and “eating/drinking behavior” (49.2%, N=122) were frequently used. In contrast, the rates of some techniques (e.g., “celebrities/a well-known person”, “scientific information”) were very low. As for the persuasive technique of “celebrities/a well-known person”, the category of product type was classified in only the “beverage” category. Thus, this study indicated that there were not many less-healthy food commercials that appealed to health and nutrition aspects of the products by using health and nutrition claims, or scientific information. In previous studies, the rate of health and nutrition claims varied between less than 10% to more than 30% (Jenkin et al., 2014). This may be due to the differences in the definitions of health and nutrition claims. Our study referred to the international standard definitions. Therefore, the findings regarding the rate of health and nutrition claims in this study can contribute to overall knowledge about the current spread of health and nutrition claims in “less healthy” food commercials of children‟s television programs. It may also be the case that food companies are acting more responsibly by limiting their persuasion techniques to those that relate to taste or convenience and not by misrepresenting the products as healthy. However, overall, the proportion of less healthy food commercials was high, and various persuasive techniques were used. At the same time, there were no commercials for fruits or vegetables presented during this time frame despite governmental regulations for eating these healthier foods. These findings suggest that more attention should be paid to the ways that certain foods are promoted (or are not promoted) among parents and policy-makers. As the sample used in this study was recorded only on weekdays and through the two kids' channels. It would be expected that the future study develop the analysis for the recorded commercials on weekends and on the other local channels. The sample used in this study was analyzed only on weekdays and through two children‟s channels. Future research might examine food and beverage advertising across different time frames and channels.
