This study was intended to investigate the sodium-related perception, dietary behavior, and practicability of methods for reducing sodium intake(RSI) according to the stage of change in consumers. The survey was conducted to 770 housewives, among them 553 subjects who answered the key questions for the stage of change were categorized into 'Maintenance (M)' stage (maintaining reduced salt intake for more than 6 months; n = 287, 51.90%), 'Action (A)' stage (maintaining reduced salt intake for less than 6 months; n=139, 25.14%), and 'Pre-Action (P)' stage (not starting reduced salt intake; n = 127, 22.97%). The subjects in M and A were significantly older than those in P (p < 0.01). The scores of desirable dietary habit and dietary balance were the highest in M followed by A and P. When eating out, the subjects in P considered 'price' more and 'healthiness of food' less than those in M and A did. Among the guidelines for RSI, 'Avoid Processed Foods', 'Eat enough vegetables and fruits' and 'Add little amount of dipping sauce for fried food' were selected as the three easiest items to perform. With regard to the sodium-related perception, the subjects in M considered eating-out food to be more salty than homemade dishes, read nutrition labels more, avoided table salt or dipping sauce for fried food more, and had 'own low-sodium recipe' than those in P (p < 0.001). It is suggested that practicability of actions for RSI and the stage of change should be considered to develop effective personalized education program and nutrition guidance.

In an attempt to examine the risk factors and analyze an odds ratio for risk factors associated with mild and moderate. severe hypertension, this study was carried out from August, 1987 to September, 1997. From periodic health examinations of insured adults, 747 subjects were assigned to nomotensives, mild hypertensives and moderate' severe hypertensives. Major findings obtained from the study are as follows: 1. The Body mass index(BMI) was revealed a significant difference among the 3 groups. Also, there was a significant positive correlation between the BMI and systolic, dyastolic blood pressure. 2. Cholesterol was revealed to be significantly different among the 3 groups. Also, there was a significant positive correlation between the cholesterol and systolic, dyastolic blood pressure. 3. Urine protein and a cardiovascular family history was revealed to be significantly different among the 3 groups. The presence of urine protein and cardiovascular family history were significantly higher in hypertensives than nomotensives. 4. A preference for salty food, a preference for flesh and the frequency of flesh eating were not significantly different among the 3 groups. 5. Smoking habits, frequency and duration of cigarette smoking were not significantly different among 3 groups. 6. The habit of alcohol consumption and the frequency and duration of alcohol consumption were not significantly different among the 3 groups. 7. The habit of exercise and its frequency and duration were not significantly different among the 3 groups. 8. Statistically significant elevated odds ratios were noted in the following BMI(mild hypertensives; 2.48, moderate. severe hypertensives ; 4.65), urine protein(mild hypertensives ; 2.37, moderate. severe hypertensives; 6.77), cholesterol(moderate. severe hypertensives ;1.64), cardiovascular family histoy(moderate severe hypertensives; 4.77). Based on these results, the significant risk factors of mild, moderate. severe hypertension were BMI, cholesterol, urine protein, and family history, but diet, smoking, alcohol consumption, and exercise had no significant association.

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.

Nutrition counselors in Korea often encounter difficulty in their attempt to change village women's attitudes regarding food taboos which are counter to good eating habits. There are a great many food superstitions which are not due to religious influence, but seem to be related to shape and composition of food. Many expectant mothers superstitiously avoid eating certain foods for fear that they may cause mental or physical abnormality in their babies. As was shown in a previous survey (Mo, 1966)of villages in all provinces except Jeju Island, such superstitions were common among pregnant and lactating mothers. Many food taboos and superstitions based on non-scientific and irrational ideas do exist even in modern society, and are a major obstacle to nutritionally adequate food consumption. A study of food taboos among women of Jeju Island was undertaken from November to December of 1976, these results to be compared as well with those of the previous study. There were 73 items found to be prohibited during pregnancy. Of these, 48.7% were of the deaf group, 17.4% fish, 5.5% eggs, 4.7% cereal, and only 2.2% fruit. Of 252% women respondents, 111 (45% ) abstained from eating chicken, duck, and shark because of the belief that they would cause their babies to be born with gooseflesh or shark skin. Many of them avoided rabbit meat for fear that their babies might be born with harelip. It was also feared that a baby would become disfigured if his mother ate duck, goat, dog meat, chicken or duck eggs, or soup made of bones. A common superstition was that highly spiced or salty foods would cause the fetus to be hairless. Squid and octopus were believed to cause babies to have weak bones, or none at all. Most of these food taboos were associated with fears concerning Physical structure and appearance of unborn babies. Other taboos were associated with fear of undesirable behavioral characteristics. For example, some mothers thought that a baby would pinch or bite the mother's breast during the weaning period, if crab meat were eaten during pregnancy. Unevenly sliced rice cake, loach, snake meat and eel were also believed to cause a baby to be ill-tempered. The findings of this study are remarkably similar to those of the previous study conducted by the authour in 1966. Most of the same food taboos, based on non-scientific and irrational reasons, were found on Jeju Island as on the peninsula, and thor were similarly wide-spread. The results of correlational analysis show that the most significant factors related to prevalence of food taboos, are level of education and religious background. Number of food taboos is correlated with level of education. Also, food taboos are least freqent among the Christian woman. Proper nutrition education should he undertaken in order to encourage intake of protein-rich food, particularly during pregnancy when nutritional needs of mother and fetus are great.

The purpose of this study is to know the effects on school lunch service programme of elementary school in rural area, by using the group consisting of the sixth year students in the schools that have provided them with the lunch for six years or longer(male student:312, & female student:324), while using the comparing group consisting of the sixth year students in the schools that have not provided them with the school lunch under their similar living condition(male student: 306 & female student:322). In addition, this study was carried out by examining all continued information about their height and weight shown in the developmetal record for six years from the 1st to 6th year, and by checking their eating habits on the basis of questionnaires. The result of this study is summarized as follows. As the result of comparing the values of their height and weight grown for 6 years, it was shown that the height of the male group provided with school lunch is 27.8 cm while the male group without lunch is 27.1 cm. And the female group provided with school lunch indicated the growing value of 29.9 cm while the group without lunch did 28.4 cm. Then, it appeared that both male and female groups provided with school lunch show higher growing values of 0.7 cm, respectively, and 1.5 cm than these groups without lunch. Also, the weight of the group without lunch was 14.8 kg. Moreover, the weight of the female group provided with school lunch was 16.9 kg while the group without lunch was 17.2 kg. Then, it was shown that the male group provided with school lunch indicates heavier growing value of 0.9 kg than the group without lunch while the female group without lunch does heavier value of 0.3 kg than the group provided with school lunch. It's figure showed that although this distribution according to percentile in the 1st year is similar to the standard regular curve it is positioned in the upper group(more thatn 70%) divided centering around 50% in the 6th year, of which distribution of children provided with school lunch was higher. When comparing the values of physical status in the 6th year, it was also shown that male children with school lunch are better than these children without lunch in jumping, throwing, chinning and lifting while female children are better than these children without lunch only in jumping, which were a significant difference. In addition, the group provided with lunch showed distribution of the higher physical grade. The result of analysis on their breakfast indicated that the children with every morning breakfast account for 67.6% of the group provided with school lunch while the group without lunch for 57.8%. Regarding the reason that they do not have the breakfast, the group with school lunch answered "Because of habits"(50.7%) while the group without lunch did "Because they have no appetite"(58.9%). When comparing the degree of preference for hot or salty food, it was apparent that these children with school lunch generally tend to prefer less hot or sailty food. With respect to the frequency and place of their eating between meals, it was shown that about 70.0% of both groups has the eating between meals, more than one time a day. Then, the group with school lunch had the eating between meals at home(45.2%) while the group without lunch did it in the process of returning to home(48.4%). Regarding the degree of their preference for a certain food, it was shown that more children of the group with school lunch do not prefer a food to others. Also, their eating attitude indicated that such children as eating the food with chat after completely swallowing food and with T.V watching are larger and lower among the group with school lunch, which showed a remarkable defference from the group without lunch. With respect to their sanitary habits such as hand washing and toothing, these children who always wash their hand before eating, accounted for 84.4 % of the group provided with school lunch while the group without lunch did for 63.6%, of which the female group with school lunch indicated a remarkable difference. The actual condition of their nutrition education showed that these children who answered "Received this education" accounted for 78.0% of the group with school lunch while the group without lunch accounted for 57.5%.

We examined the obesity levels and dietary habits of 323 college students taking the course 'Health and Diet' as a part of their nutritional education. The average percentages of body fat, BMI and RBW for subjects in this study were 16.7%, $21.5kg/m^2$ and -1.2% in male students and 27.3%, $21.2kg/m^2$ and 1.0% in female students, respectively. BMI and RBW indicated fewer cases of obesity among female students than BIA did. The average intake of energy by subjects was lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDA of energy. In particular, the average intakes of calcium, iron, and vitamin A by female students were much lower than the RDAs of each of those nutrients. The percent RDAs of nutrient intakes of energy, protein, thiamin, and riboflavin were lower in under weight students than in students of normal and over-weight. Female students were found to skip meals and consume sweet foods more frequently than male students. The obesity levels of students related to the number of meals eaten per day as well as the frequency of consuming sweet foods. Although, it was not possible to determine statistically, the levels obesity also seemed to correspond to the speed at which meals were eaten as well as the frequency of eating salty foods. These results suggest that in order to assess obesity properly, more research that focuses on subjects' gender should be conducted. In addition, nutritional education should emphasize the importance of intakes of energy and phosphorus for male students, and the danger of iron and calcium deficiencies for female students. We should also educate students about dietary habits which contribute to obesity such as overeating and the intake of sweet foods.

The purpose of this study was to investigate dietary intake and to evaluate patient satisfaction toward the quality of hospital foodservice. Questionnaires were distributed to 203 hospitalized patients in 3 hospitals having 300 beds. The intake rates for served amounts of rice, side dishes, and soup were 72.5%, 68.2%, and 62.6%, respectively. The main reasons for left-overs were 'no appetite' (25.8%) and 'not salty enough' (19.9%). The rate of patients eating outside food was about 33.5%. The average score for quality satisfaction of meal characteristics was 3.34 ${\pm}$ 0.61, and the average score for quality satisfaction of sanitation and service characteristics was 3.58 ${\pm}$ 0.61. 'Seasoning' showed the lowest score and 'temperature' showed the highest score for quality satisfaction of meal characteristics. In the quality satisfaction of sanitation and services, 'explanation of meals' showed the lowest score and 'exactness of meal times' showed the highest score. The patients hospitalized for 10 days showed significantly lower average scores than those hospitalized over 60 days for quality satisfaction of meal characteristics. The patients with 'little appetite' and 'regular appetite' showed significantly lower average scores than those with 'much appetite' for the quality satisfaction of meal, sanitation, and service characteristics. The patients who 'rarely had leftovers' showed significantly higher average scores than those who 'always had leftovers' and 'often had leftovers' for quality satisfaction of meal characteristics. Meal characteristic scores were significantly correlated with age (r = 0.216), length of admission (r = 0.310), appetite (r = 0.251), leftovers (r = 0.233), and intake of soup (r = 0.205). Also, sanitation and service characteristics scores were significantly correlated with age (r = 0.327), education (r = -0.202), length of admission (r = 0.168), and appetite (r = 0.155). Thus, it would seem to be desirable that hospital foodservices improve the taste and seasoning of meals and provide appropriate nutrition education and counseling in mid-sized hospitals.

The purpose of this study was to understand the characteristics of senior consumers' food-related lifestyle and to investigate their demand for menu development of senior' friendly food products. An one-to-one survey method was used for data collection, and the survey was conducted with 490 senior participants who are over 55 years-old living in Seoul and Kyunggi area. The main results of this study were as follows: Most participants usually spend from 60,000 to 150,000won on food a month, and the female participants played a decisive role on food purchasing and preparation. They preferred home meal for their three regular meals to bread, convenience food, or eating-out. For menu development of senior-friendly food products, the demand for food products using moist-heat cooking method was higher than those using dry-heat cooking method. Also, the respondents did not like strong taste such as salty, spicy, or bitterness in senior-friendly foods, and wanted to have a variety of noodle, kimchi, meat, seafood meals.
