In order to give basic data to teenager's healthcare, we investigated the food habits according to BMI (Body Mass Index), life style, dietary related self-efficacy and food intake through conducting a research surveying 732 middle school students of the Kwang-ju and Chonnam areas. The results of this study were compared groups in under weight (UW), normal weight (NW), and overweight (OW) groups according to BMI levels. In the male students, height was significantly differently in the UW group as $158.2\pm0.7$ cm compared to other NW and OW groups respectively as $163.7\pm0.6$ cm and $162.6\pm0.7$ cm but in the female students there was no significantly difference within groups. Weight was significantly different between the groups in the male students, whereas there were minor differences in the female students. The average of BMI was $20.7\pm0.1$ on the male students and $20.6\pm0.1$ on the female students which were all within the average, and their obesity was increased as the school grade was higher. Under less than 30,000 won of pocket money was dominating, and most of the students were in a nuclear family. In all male and female students, the inactive hours like watching TV and using computers had no differences between groups. The difference between groups was minor on breakfast time and most of the students thought their problems on unbalanced diet. There was significant difference in the OW group in female students as they thought their problems on unbalanced diets. The frequency of snack was significantly low in the OW group of male students but there were no differences in snack and eating-out food. All students chose fruits as snack food and Korean-style food as eating out food. The OW group in male students were significantly low in the dietary related self-efficacy when they were with their families and feeling depressed but there were no differences in female students between groups. When all students were getting higher BMI, they evaluated themselves badly in their self-dietary habits. Also the more male students had non-physical activity time, the less they had the dietary related self-efficacy and the more female students had physical activity time, the higher they had the dietary related self-efficacy. In conclusion, the OW group had good habits in physical activities for weekends, meal times, frequency of snack consumption but it showed undesirable when they were low in dietary related self-efficacy. Therefore we will provide the systematic nutrition education to them through this study.

We studied daily micronutrient intake from vitamin-mineral supplements, health-related life style, clinical case of diseases and food frequency of the Korean middle-aged (40-59 yr, n = 404) to compare the characteristics of non-user (n = 270) and user (n = 134) of vitamin-mineral supplements. Rate of supplement use of the middle-aged was 33.2% and there was significant difference in education level (p = 0.0084) and family income (p = 0.0476) of user and nonuser. Smoking habit (p = 0.0844) and drinking frequency (p = 0.0606) tended to be lower in a supplement user than a non-user. The medical history of a case was significantly higher in users (67.9%) than in non-users (44.4%) (p = 0.001), which suggests that medical history is one of the important motivations of supplement use. Supplement users had the medical history of digestive disease (34.1%), anemia (11.0%) and hypertension (9.9%) in order. Vitamin C was the most frequently supplemented nutrient (81.3%) among vitamin-mineral supplement, and the next orders were vitamins E (73.1%), B$_2$(68.7%) and B$_{6}$ (60.4%). Mean intakes of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was 4,260%, 4,030%, 1,660% and 1,330% of RDA, respectively. The supplement users tended to consume most food items including milk ＆ milk products (p ＜ 0.01), rice (p ＜ 0.01), grains (p ＜ 0.05) and cookies (p ＜ 0.01) less frequently than non-users. Conclusively, nutrient intake of vitamin B$_1$, iron, selenium, vitamin E, and vitamin C from supplement was excessively high compared to RDA. We suggest that the toxic effect of excessive supplementation should he informed to supplement user and nutritional education should be focused on the optimal supplement dose.e.

Objectives: Stress during adolescence is related to undesirable nutritional intake and negatively affects the growth and development. This study was performed to investigate the relationship among life stress, dietary behaviors and the intake of high-fat containing snacks in male and female high school students in Gyeonggi-do area. Methods: The subjects were 700 high school students (350 males, 350 females) in Gyeonggi-do from July to September 2014 and the survey was performed by using questionnaire that included general characteristics, dietary behaviors, high-fat containing snacks intake, and daily life stress. Results: There was a gender difference in health-related life style and dietary behaviors, and the life stress was significantly higher in female students than in male students. For health-related life style, exercise frequency, hours of sleep and conversation time with parents had significantly negative correlations with life stress, while smoking and perceived stress had significantly positive correlations with life stress. For dietary behaviors, the frequency of eating-out had a significantly negative correlation with life stress, while the changes in amount of meal intake under stress had a significantly positive correlation with life stress. The fat intake of 'high-stress group' was significantly higher and high-fat containing snacks consumed by this group consisted of cookies, honey bread and fried foods. Conclusions: It is necessary to develop appropriate programs for the emotional stability and stress relief of adolescents that provide continuous nutrition education focused on proper snack intake, desirable dietary behaviors and nutritional aspects.

The objectives of this study were to classify the types of elderly households and to compare the characteristics of their dietary lifestyle. Panel data surveyed by Korea Rural Economic Institute (KREI) for Food Purchase Attitudes over three years (2019 - 2021) were utilized for the analysis. Through a factor analysis, five common factors were extracted out of 19 basic variables related to dietary style, which indicate two kinds of consumer competency index (safe diet, traditional diet) and three kinds of purchase frequency (healthy food, meat & fish, fresh seafood). Applying the cluster analysis method, by using socioeconomic variables along the five common factors, elderly households aged 60 or older were grouped into four types. As a result, Type 1 elderly households accounted for 50.8%, Type 2 for 16.2%, Type 3 for 27.8%, and Type 4 for 5.2% out of all 870 elderly households. Type 1 is characterized as a low-income vulnerable class with a poor diet, Type 2 as a middle-income class with a healthy food-oriented diet, whereas Type 3 was classified as a middle-income class with a meat-oriented diet, and Type 4 as a high-income class with diverse dietary culture. It is necessary to expand the agri-food voucher pilot project to the entire country and also increase the monthly subsidy for the Type 1 elderly households. Implementing community kitchen projects for elderly single-person households, promoting senior internships by providing incentives to companies that employ retirees, the provision of education by local governments on a safe and balanced diet for Types 2 and 3, and the promotion of an elderly-friendly social environment are also recommended.

This study was performed to investigate the effects of food habits and life style on the skin health of young Korean females in their late teens and twenties. The study focused on facial skin and used a self-administered questionnaire survey, an examination of skin type, and pH tests. More than half of the females had combination skin type or pH level higher than 5.8 which is regarded as normal. The variables that turned out to significantly (p<0.05) effect their facial skin types were body mass index (BMI), the type of residence, the amount of water intake, whether or not they intake drinks, the frequency and amount of alcohol drinking, favorite foods as side dishes at meals, intake frequency of fruit, the dairy, seaweed, and fast food, the frequency of washing their faces per day, the method of how they used water during face washing, whether or not they had professional skin care, and whether or not they wore color make up. The variables of the females' age, BMI, the amount of alcohol drinking, the frequency and duration of exercise, the controlling methods of stress, their favorite foods as side dishes at meals, and the intake frequency of soy products or animal foods significantly affected their facial pH levels (p<0.05). The results of this study indicate that some food habits and life styles are significantly related with facial skin health. More importantly BMI and favorite foods as side dishes during daily food intake could have remarkable effects on facial skin health.

This study was conducted to evaluate the health status, life style, dietary habits and nutritional status of 44 industry workers that were routinely exposed to unclean environments while consuming 3 major pork dishes 2 times a week for 6 weeks. The health status, life style and dietary habits of the workers were investigated by a survey questionnaire, and the nutritional status was evaluated using the 24-hour recall method. Overall, the subjects reported that their health status was fairly good throughout the year, but that they felt dizziness and fatigue often. In general, the subjects did not exercise regularly and drank alcohol very often. The average daily energy intake increased from 1,708.3 kcal to 1,859.5 kcal without a change in the BMI or WHR when the respondents were fed pork dishes. However, the mineral intake did not differ significantly in response to the consumption of pork, although the Zn intake tended to increase. Moreover, the vitamin $B_1$, niacin, and E intakes increased after consuming pork(p<0.05), while the cholesterol intake decreased from 425.2 mg to 356.7 mg after eating pork(p<0.05). Additionally, both the fat intake and the PUFA intake increased after the consumption of pork with the intake of oleic, linoleic and linolenic acids increasing significantly(p<0.001). Finally, the intake of essential amino acids also increased significantly in response to the consumption of pork(p<0.01). Based on the results, regular consumption of pork dishes improved the nutritional status of industry workers without any adverse effect in terms of the intake of relative fat and cholesterol.

The purpose of this paper was to clarify the actual conditions of the 'Dietary externalization' mainly by using the economic and nutrition-related data, accompanied by the economic development in Korea and Japan. 'Modernization of food style' and other modernization have taken place, among which 'Dietary externalization' in particular has recently drawn interest. At the time this paper clarified with econometric analysis whether there are differences between the two countries in term of the modernization of food style and dietary externalization trend. The trends of Dietary externalization of both Korea and Japan were studied using Principal Component Analysis method. The food subgroup were investigated based on the annual report on the household income and expenditure survey of Korea and the annual report on the family income and expenditure survey of Japan. The statistical data from both country were analyzed by SAS program. The results are as follows; 1. In Korea, the ratio of carbohydrates in the total calorie intake is quite high and animal protein is rather low compared to those in Japan. 2. Traditional food such as grains and vegetables are consumed much more in Korea than in Japan. 3. The Principal Component 1, 2 were extracted in both countries during the whole analysis period, which suggested the 'Dietary externalization' 4. Principal Component 1 has a positive factor loaded in all food items including meals outside the home and process food. In other words, it is apparent that the 'Dietary externalization' tread in Korea has a simple pattern suggesting that all externalization related items are on the rise. 5. Principal component 1, 2 which indicated the dietary externalization, were detected in Japan.

This study was conducted to investigate and analyze food related and space related elements of popular Vietnamese restaurants in Hong Kong to identify restaurant images related to food, to examine how Vietnamese traditions are applied to such restaurants, and ultimately, to get their implications for us. Luxury Vietnamese restaurants in Hong Kong tended to be located in major office buildings and famous shopping malls in the downtown area; therefore, they were highly accessible to foreigners. In addition, most Vietnamese restaurants were quite formal in size or atmosphere. The food-related elements of the luxury restaurants reproduced traditional menus, but the table setting and service generally adopted a formal Western style setting. The presentation of foods was also creative and contemporary, to suit international customers' tastes. Regarding the spatial elements, restaurants serving traditional menus had interiors influenced by the French colonial period, while those serving contemporarily adapted menus had interiors with simple contemporary images emphasized by Vietnamese traditional decorations. These characteristics allowed foreigners from diverse countries to access the restaurants without a sense of rejection. Casual restaurants were primarily exposed to many people on busy roadsides, but they tended to be inferior in terms of size and quality. Apart from size and price level, food-related elements failed to reflect Vietnamese unique traditional characteristics. The outward appearance consisted of basic construction materials (glass, chassis, and bamboo) instead of those representing Vietnamese architecture. Additionally, the interior of the casual restaurants contained traditional elements or objects more frequently than luxury restaurants, but they looked rather disorderly and lacked harmony. Overall, the image of casual restaurants was degraded by the use of cheap and low quality finishing materials and furniture. The results of this study may be useful for organizations promoting the Branding of Korea or businesspeople and designers promoting the globalization of Korean foods.

This study analyzed the willingness to pay for meal kit products of Millefeuille Nabe and Gambas al-Ahiyo, and willingness to pay and purchase intentions according to various characteristics to suggest a meal kit marketing strategy that reflected consumer preference. It was found that the price of meal kits is higher than the price of individual ingredients and lower than the price of meal kits in the current market. The willingness to pay for Millefeuille Nabe is higher in the group that pursues quality and taste, and the more satisfied with the certification system, the higher their willingness to pay for both Millefeuille Nabe and Gambas al-Ahiyo. In addition, the higher the satisfaction with the pleasure, taste, and price of the meal kit, the higher the intention to purchase in the future. Therefore, to increase the willingness to pay and purchases intentions in the future, the quality of meal kit ingredients must be carefully revised and supplemented, and various products are developed and reflected in the marketing strategy.

Hyperlipidemia and related heart disease will be growing public health problems as the population ages. It is therefore of great importance to identify modifiable risk factors. So this research investigated associations among life style, nutrient intake, and blood lipids in middle-aged men with borderline hyperlipidemia. Dietary intakes were assessed by food-frequency questionnaire and convenient method. The subject's histories of alcohol use and smoking were assessed via a questionnaire. Current smokers were classified as smokers, whereas past smokers and subjects who never smoked were classified as nonsmokers. With regard to alcohol intake, the subjects were stratified into drinkers and nondrinkers. In drinkers the frequency were measured. Frequency of alcohol intake and weight were associated with high blood lipids and blood pressure. The highest quartile of calcium intake had lower triglyceride concentration than did those in the lower three quartiles. High calcium intake was associated with low blood triglyceride concentration. These results suggest that healthy weight and high calcium intake and less alcohol intake can contribute to maintenance of healthy blood lipids in men.
