Objectives: Rapid economic growth and industrial development in South Korea have led to a great change in dietary patterns, and the use of convenience foods has continuously increased. This study was performed to evaluate the energy and nutrient contents of convenience foods at convenience stores near the universities as a meal. Methods: Data was collected by visiting 22 convenience stores near some universities in Chungbuk and Seoul and by checking nutrition labels on convenience foods at the stores. Data of a total of 338 food items were collected, and divided into five groups according to the food categories; rice products (n=156), noodles (n=101), burger/sandwiches (n=62), Tteokbokkis (n=11), and dumplings (n=8). Further, rice products, noodles, and burger/sandwiches were divided into subcategories. Results: The proportion of calories from carbohydrates was high in the rice products and tteokbokki, while the rate of calories from fat was high in burger/sandwiches and dumplings. Among the rice products, the proportion of carbohydrate calories was high in a one-dish food, rice with soup, and triangular kimbap, while the proportion of calories from fat in lunch boxes was high. In the noodles category, ramyeon and spaghetti had a high percentage of fat calories, while udong had a high percentage of carbohydrate calories. The ratio of the calorie content in relation to the KDRIs for adults aged 19-29 years, lunch boxes provided about 1/3 of daily required energy. However, the amount of calories as one meal was not enough for other types of rice products except for lunch boxes. Ramyeon was high in calories, fat, and sodium, but low in protein content. The burger/sandwiches had a high percentage of fat and sodium. Conclusions: Our results showed several nutritional limitations of convenience meals in convenience stores according to the type of food. Therefore, college students should limit excessive intake of convenience meals on a regular basis in order to avoid unhealthy food intake patterns. Our results demonstrate the need for educating college students with regard to checking nutrition labels when choosing convenience meals in order to facilitate the selection of food items that contribute to a balanced diet.

Food and nutrition sites are the major portion of the health information sites. For the point of public health it is very important to secure validity and reliability of information on those web sites. Therefore, in this study we would like to identify problems when acquiring recipes in web sites by analyzing and reviewing recipes in web sites. To investigate Korean food recipes provided in web sites, domestic search engines such as Simmani, Naver, Hanmir, and Empas and foreign search engines such as Yahoo Korea, Lycos and Altabista Korea were used. Searchs were done using 'recipe' and 'Joribeob (cooking method)' from March 20, 2002 to June 20, 2002. Informations in each sites were reviewed and analyzed Results are as follow; When classifying 46sites searched with 'Joribeob' by the information provider, 24sites were individual, 16sites were corporate and 6sites were others. When searching 'recipe', total 12,654recipes were returned. Out of them, individual provided 2,581sites(20.4%), corporate provided 7,249sites(57.3%), and others provided 2,824sites(22.3%). 9,979(78.9%) recipes out of 12,654recipes were proved to be appropriate as Korean food. Classifying recipes by dish group, vegetables 11.7%, soups and hot soups 9.7%, stew and casseroles 8.2%, pan cakes 8.0%, stir fried foods and skewers 7.8%, rice 7.2%, hard boiled food 7.1%, steam 6.4%, noodles and mandu 5.3%, Kimchi 4.5%, fried 4.1%, and porridge 3.7% in order. 21.1% of recipes were not appropriate as Korean food but provided as Korean Food. The proportion of individual as the information provider were higher than that of enterprises. Recipes from enterprises were based on food and nutrient information and more reliable. However, there were some cases that they provided the same amount of ingredients with different calories or provided the same calories with different ingredients. Additionally, depending on sites, they provided different calories even for the same recipe. There were some cases that the calories provided on the site were too high or too low, for the suggested amount of ingredients and serving size. Recipes those provide amount of calories were evaluated using the nutrient analysis program. Calculated calories and provided calories on the Web were compared together. There are difference between two valus. With these results, it may lead misuse of recipe by those who need accuracy in diet such as patients or who are interested in recipe information for academic purposes. These results could be used as basic materials to improve quantity and quality of recipes in the future. Also, to improve the accuracy of recipies for Korean foods in the web sites, there should be some systems to monitor and let internet users know monitoring results.

BACKGROUND/OBJECTIVES: The commercial foodservice industry in Korea has shown rapid growth recently. This study examined Korean adults' consumption of commercially-prepared meals based on where the food was prepared. SUBJECTS/METHODS: Data from a 24-hour dietary recall of the 2001 and 2011 Korea National Health and Nutrition Examination Surveys were analyzed. A total of 10,539 subjects (n = 6,152 in 2001; n = 4,387 in 2011) aged 19-64 years were included for analysis. Commercially-prepared meals were classified into four food source groups based on where the food was prepared: Korean restaurants, Chinese/Western/Japanese restaurants, fast-food restaurants, and retail stores. Subjects' energy intake, including the amount and proportion of calories, was examined for each food source. The analysis was also conducted by gender for age-stratified groups: 19-29, 30-49, and 50-64 years old. RESULTS: Korean adults' energy intake from commercially-prepared meals increased in the amount of calories (551 kcal to 635 kcal, P < 0.01), but not in the proportion of daily calories (27% to 28%) from 2001 to 2011. The most frequent food source of commercially-prepared meals was Korean restaurants in both years. The amount and proportion of calories from retail stores increased from 83 kcal to 143 kcal (P < 0.001) and from 4% to 7% (P < 0.001), respectively, during the same period. Males aged 30-49 years (34%) and females aged 19-29 years (35%) consumed the highest proportion of daily calories from commercially-prepared meals in 2011. CONCLUSIONS: Korean adults consumed about one-fourth of their energy intake from commercially-prepared meals. In particular, males aged 30-49 years and females aged 19-29 years consumed more than one-third of their energy intake from commercially-prepared meals. Korean restaurants played a significant role in Korean adults' energy intake. Retail stores increased influence on Korean adults' energy intake. These results could be useful for developing health promotion policies and programs.

This study was conducted to investigate that the nutrition labeling use is associated with demographic and psychosocial factors according to each nutrition information on the nutrition labeling in Korean adults. The study subjects (N=1,140) were individuals who were aged 20 years and more and answered on the question of nutrition label use and who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2010.As age older, there was more interest in information such as sugar, protein, fat, cholesterol than calories. In contrast, as age younger, there was more interest intrans-fat, sodium as well as calories. As higher education level, there were more aware of trans-fat, sodium and calories. From the result that the most interested nutrition items were significantly different by democratic factors, we could understand interested nutrient information on the nutrition labels could change according to individual specific education. Therefore, this can also provide basic data for systematic education program by nutrition label use.

The objectives of this study were to conduct preliminary research to investigate full course meals in Korean style restaurants in order: i) to analyze the nutrient contents of full course meals per servings, and ⅱ) by analyzing the above, to examine the amount and the quality of the foods served in the full course meals by Korean style restaurants in Changwon. A total of 20 restaurants in Changwon participated in this study, and two investigators visited there, consumed and investigated it. A key finding was that restaurant patrons tended to overconsume nutrients as compared to the Korean Recommended Daily Allowance(RDA), and restaurants generated large amounts of food wastes due to the excess food served. Other findings were as follows: 1) 1,821.2Kcal were served, 1,052.6Kcal were consumed and 768.6Kcal which is equivalent to 1/3RDA were thrown away on average. 2) The average carbohydrate:protein:fat(CPF) ratio of caloric nutrients was 42:27:31. 3) The correlation between the consumed and unconsumed calories was r=0.661 and the correlation between served and unconsumed calories was r=0.819. Both consumed and unconsumed calories were closely related to the served calories. 4) The result of the research showed that mean INQ in most nutrients was higher than 1.0, especially INQ in unconsumed food is mostly higher than INQ in provided and consumed food. 5) The unconsumed food and the meal prices were closely correlated in terms of price loss. These findings indicate the Korean style full course meals consisted of a high-protein, high-fat and high-caloric intake, which is similar to a westernized caloric nutrient pattern. They should also be strongly encouraged to play an active role in improving their customers’ nutritional status, as well as reducing the restaurants wastage of food. Lastly, further research should be conducted to improve the quality of the menus in Korean restaurants.

This study is based on data from the food consumption survey on 727 members of 125 farm households from 7 different provinces. The survey was conducted in May, 1975 in cooperation with the O.R.D. The results obtained in this study are summarized as follows. 1. The average consumption of the basic food groups per capita per day was 563 g for cereals and grains(398g of rice and 129g of barley), 87.6g for meats and legumes, 317.8g for fruits and vegetables, 25.7g for milks and small fishes, 9.1g for fats and oils, and 45.1g for other group. 2. The average daily consumption of calories and nutrients was 2256 cal and 11.7g for animal proteins, 70.5g for total proteins, 21.6g for fats, 537.4mg for calcium, 18.1mg for iron, 5375lU for vitamin A, 1.27mg for thiamine, 1.05mg for riboflavin, 15.5mg for niacin, 77.7mg for ascorbic acid. When these figures are compared with the recommended allowances for Korean, the calories and nutrients intakes were satisfactory, except for the intakes of animal protein which was below two third of the recommended allowance. 3. The diets of the projected villages differed from those of the non-projected villages in the following respect: (a) The amounts of animal proteins and fats were larger in the projected villages than in the non-projected villages. (b) The percentage contribution of fats to the total amount of calories from three nutrients, carbohydrates, proteins and fats was higher in the projected villages than in tile non-projected villages. (c) The percentage contribution from carbohydrates to the total amount of calories was higher in the non-projected villages than in the projected villages. 4. Certain physical and clinical symptoms were observed among the people in the rural areas, which can be related to the shortages of animal proteins and fats in their diets. It is recommended to pay special attention to the nutrition of school children in the Korean rural areas.

This study is intended to reveal the nutritional realities of school children due to their box lunch. The samples were chosen at random from the third grade to the sixth grade children in an elementary school in Seoul : 122 male and 111 female children, 233 children in all. among the subjects, 44.3% have a family of four, 34.3% have over 500,000 won of family income a month, and 44.3% of their mothers graduated from a high school. The average intake of calories is 573.6 Kcal, and the ratios of the calory intakes to the recommended amounts are 90.6% in the third grade children and from the fourth grade to the sixth grade, 79.5% in the male children and 82.9% in the female children. The average consumption of protein is 21.0g and the ratio of animal protein is 41.4%. the ratio of energy yield nutrients is 67.4% : 14.5 : 18.0 (carbohydrate : protein " fat). Considering the recommended amounts, the intake of protein is enough; the consumption of vit, A, thiamine, niacin are appropriate;and the intake of calories, Riboflabin and ascorbic acid, calcium, iron are deficient. Even though there is no significant difference between the socioeconomic factors (the standard of education of the subjects' mothers and family income0 and the intakes of calories and protein, there is a tendency that the consumption of protein intake si more abundant in the middle class than in any other class. The subjects' distribution of the physical growth index, is as follows; A (6.9%), B(19.3%), C(48.5%), D(13.7%) and E (11.6%). As the subjects' intake of calcium increases, the weight shows significant improvement (p<0.001). As the consumption of calories increases, the physical development shows significant improvement (p<0.05), and the weight shows significant increase (p<0.001).
