An emerging interest in healthy eating has led to an increase in the consumption of rice mixed with various types of grains. Cooked rice was prepared with five different seaweeds, Hizikia fusiformis, Sargassum fulvellum, Enteromorpha compressa, Undaria pinnatifida, and Gracilaria verrucosa, and the antioxidant activity was measured. In addition, the antioxidant activities of 80% ethanol and methanol extracts of the five seaweeds were compared. Total phenolic content (TPC), total reducing power (TRP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) cation radical scavenging activities of the ethanol extracts were higher than those of the methanol extracts. The TPC of raw seaweed ethanol extracts was from 7.58 to 26.27 mg gallic acid equivalent (GAE)/g. The antioxidant activities of both extracts of Hizikia fusiformis were the highest among the five seaweeds, and the antioxidant activities of the cooked rice were lower than those of the raw seaweed extracts. The DPPH radical scavenging activities of cooked white rice, mixed grains, barley, and a mixture of white rice and barely added with Hizikia fusiformis, Sargassum fulvellum and Undaria pinnatifida were 3.17, 23.12, 31.11 and 10.66%, respectively. These results demonstrate the addition of seaweeds to cooked rice helps to improve the antioxidant activity compared to white rice alone.

This study was designed to assess diet and health-related factors of older adults in Korea. Subjects females were 2,660 adults aged 50 and over living in Korea. Males were 847 persons and were 1813 persons. The mean weight and height for males and females were 63.8 $\pm$ 0.3kg / 164.0 $\pm$ 0.2cm and 57.0 $\pm$ 0.2kg /150.6 $\pm$ 0.1cm respectively. BMI (body mass index), body fat, and percent fat were significantly greater in females than in males. The muscle mass and body water were significantly greater in males than in females. Twenty-one percent of total subjects lived alone and 26% with spouse only. Most of the subject's self-reported income was in middle level (65%) or low level (24%). Proportion of subjects who answered 'very poor' or 'poor' on perceived health status was higher in older group. The 50-64 years old group was facing more stress than 65yr and over group. Among male subjects,38.4% were current-smokers and 22.0% were ex-smokers. But only 6.5% of female subjects were current-smokers. Males turned out to have better dietary habits-meal frequency per day, mealtime regularity, regular meal size and balanced eating-than females (p < 0.001). This study revealed that the diet and health-related factors affect nutritional status and chronic diseases of the elderly. For better management and evaluation of health status of the elderly, more effective nutritional assessment tools should be developed.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.

Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

The number of school lunch-supported children who belong to low-income families has been rapidly increased in Korea. This study was aimed at evaluation of nutritional status of school lunch-supported elementary school children. One hundred school lunch-supported children and 119 non-supported children of fourth to sixth year class in 3 elementary schools in Gyeongbuk rural area were selected, and surveys were conducted twice, i.e., once during school term and once during summer vacation in 2006. Food consumption survey during school term was carried out through an interview by dieticians at school-lunch time using a 24-hour recall method, and the survey during summer vacation conducted by recording food intakes for three days by children. Nutrient intakes were calculated using CAN-Pro 3.0 program. School lunch-supported children showed higher rate of skipping breakfast and rather irregular meal time as compared to non-supported students. Eating alone was more frequent in school lunch-supported children than in nonsupported children. The average nutrient intakes and nutrient adequacy ratios were lower in supported children than in non-supported children. During term, percentages of nutrient intakes provided by school-lunch were higher in supported children than in non-supported children. Intakes of energy nutrients were within acceptable macronutrient distribution ranges, but proportion of carbohydrate intake increased during vacation. Analysis of patterns of food intakes based on major food groups (dairy, meat, grain, fruit, vegetable) indicated that meals during term were more balanced as compared to meals during vacation. In conclusion, food behaviors and nutrient intakes of school lunchsupported children were inferior to those of non-supported children during term and during summer vacation. They were provided with more nutrient intakes from school lunch during term as compared to non-supported children. Therefore, it is necessary not only to keep meal support program during vacation but also to provide a proper nutrition education as a part of school lunch program to improve nutritional status and food behaviors of school lunch-supported children.

The purpose of this study were to identify the dietary practices of vulnerable older adults and to assess the foodservice and food provision service programs perceived by the health and welfare service providers in the community. A survey was conducted on health and welfare service providers working in outreach community centers and community health centers in Seoul. A total of 260 nurses and social workers participated in the survey and 224 responses were used for data analysis after excluding significant missing data. The respondents consisted of nurses (58.5%) and social workers (41.5%). In terms of the dietary life of the vulnerable older adults, they perceived that the food cost was burdensome to the older adults and poor dental conditions prohibited them from eating various foods. The health and welfare service providers rated highly for 'home-delivered meal and side dish services are effective for checking older adults' conditions' but rated low for availability of menu choices. In targeting vulnerable older adults for food and nutrition service programs, the home-delivered meal service was found to be suitable for older adults living alone, those over age of 80 years, those with mobility difficulties, and those with economic difficulties. The food provision service was appropriate for older adults living with their spouse or other family members. Vulnerable older adults are a heterogeneous population with diverse needs related to food and nutrition. Home-delivered meal/side dish service and food provision services will achieve their goals when they reach the correct targets with a customized service.

Purpose: With increased time spent at home due to prolonged online classes, this study sought to determine how the coronavirus disease 2019 (COVID-19) pandemic has impacted the mukbang- and cookbang-watching patterns and dietary life of college students. Methods: All students majoring in food and nutrition (FN) at a college in Gyeonggi, Korea, participated in the survey in April 2019 (M/F = 36/106) and June 2020 (M/F -37/130) and data were analyzed using SPSS 26.0. Results: Compared to students responding in 2019, those in 2020 reported more frequently eating alone (p < 0.01) and cooking (p < 0.01), and evaluated their diets better regarding pleasant mealtimes atmosphere (p < 0.05), moderation in drinking (p < 0.05), and not consuming excessively delivery foods (p < 0.001), processed foods (p < 0.01), foods with animal fat (p < 0.01), salty foods (p < 0.01), and sweets (p < 0.01). Although the proportion of respondents who answered that they watched mukbang and cookbang at least occasionally did not change, greater proportions of respondents reported watching both genres frequently (p < 0.001, respectively) and spending less time/day in watching mukbang (p < 0.05) in 2020 vs. 2019. While they evaluated the effect of mukbang- and cookbang-watching on overall diet similarly, the proportion of respondents that reported feeling as though mukbang-watching prompted them to eat more of less-desirable foods decreased from 54.3% to 41.5% (p < 0.05). Diet improvement of participants due to COVID-19 resulted in that the association between frequent mukbang-watching and unhealthier dietary habits in 2019 was not shown in 2020. Conclusion: Our results suggest that the prolonged at-home stays due to COVID-19 might have improved many aspects of diet and decreased undesirable effect of frequent mukbang-watching in case of college students majoring in FN.

Objectives: This study examines the effect on the frequency of ramyeon consumption based on who checks nutrition labels and on the levels of sodium-related nutrition knowledge among middle school students in the Incheon area. Methods: Self-administered questionnaires were completed by 359 students (143 males and 216 females) from May to October 2021. General information as well as ramyeon-eating behaviors were surveyed. The frequency of ramyeon consumption was compared depending on who checks nutrition labels and on the amount of sodium-related nutrition knowledge students have. Both 𝛘² tests and t-tests were conducted for categorical and mean comparisons. Results: Regarding the consumption of ramyeon, 46% of the students replied that they eat it alone at home. The criteria for choosing the kind of ramyeon to eat were taste (79.4%), price (9.2%), brand and new products (4.5%), nutrition (2.2%), weight control (2.2%), and other factors (2.5%). When purchasing ramyeon, more students replied that they did not read nutrition labels (66.0%) compared to those who did read labels (34.0%). Answers to questions on sodium-related nutrition earned an average of 6.84 out of nine points (males, 6.72 points, females, 6.91 points, ns). The average frequency of ramyeon consumption was 1.67 times per week (males, 1.66, females, 1.68, ns). The frequency of ramyeon consumption by students who checked nutrition labels was lower than for students who did not check labels (1.44 times per week vs. 1.79 times per week, P < 0.05). Conclusions: Students who checked nutrition labels reported a lower frequency of ramyeon consumption than students who did not check them. Education on checking nutrition labels may reduce the consumption of processed foods such as ramyeon and may lead to making healthy choices when purchasing food.
