This research involved a survey on the dietary patterns of children and adolescents living in group homes, to find out their wrong eating habits and to devise measures for correcting their problems. The BMIs of the subject children and adolescents in group homes were measured, and the result showed that although many of them appeared to have normal weights, about 42.2% were actually underweight. Most of them had meals regularly, three times a day at fixed times. However, half of them frequently skipped breakfast because of the lack of time in the morning. In addition, more than half of them had the habit of having imbalanced diets, especially with low vegetable intake. The score for their satisfaction toward meals at group homes were highest (3.97) with the taste of food, while it was relatively lower (3.61) with the variety of food than with the other items. The average score for their snack intake was 3.47, showing that the majority of them had the habit of eating snacks, while the largest portion (26.0%) of them preferred bread and cookies. According to the result of the analysis on their food intake, overall calorie intake was about 82~96% of estimated energy requirements, while that of the male subjects aged 12 or older was about 82% of the standard energy requirements. Their overall intake of calcium and potassium was lower than recommended nutrition intake, but sodium intake was higher than 3 times recommended intake. Especially, in addition to calcium and potassium, the male subjects aged 15 or older showed low intake of dietary fiber, iron, zinc, riboflavin, niacin, vitamin C and folate also; whereas the female subjects aged 15 or older showed low intake of iron, zinc, riboflavin and folate also. Taken together, it was concluded that government level of dietary life-related support and management would be necessary for the healthy growth and development of children and adolescents in group homes.

Rice production in Korea began to rise significantly after 1970. Rice is the dominant food in Korea and most of the rice production (about 95%) is consumed as cooked rice. it provides over 4,000Kj of energy per capita per day. Apparent rice availability in 2000, 93.6Kg of milled rice per person annually. The non-allergenic character of rice offers a sound basis for development of products for markets for all age groups. Whole grains are washed rice, coated rice, enriched rice in Korea. Utilization of rice as food can be categorized three categories in Korea; direct food use, processed foods, and brewing. Rice for direct consumption include regular whole grain, precooked rice, brown rice and specialty products such as aseptic cooked rice, retort cooked rice and rice burger. Rice used for processed foods includes that for cereal, soup, baby food, snack, cake, noodle, brown rice tea, and minor unclassified uses. Rice use for brewing is for the production of fermented rice wine. The use of rice for direct food is by for the greatest of the three uses. Although direct food accounts for the largest domestic consumption, a significant quantity of rice is used in processed products. The use of rice by-products as human food should not be over looked. Utilization of by products(rice germ, rice bran) requires a specialized technology. Typical type of rice is black rice. When cooked, black rice gives a black color to cooked rice. Glutinous rice performs specific functions in several commercial products such as dessert, gravis, cake and snack. Rice starch production is quite limited because of the high cost of making of starch. Rice processed products in Korea are occupied small parts of total rice production compared to Japan. Rice cake (Garadog) is the principal from of rice product consumed in Korea. Rice cake and snack is usually prepared from non-glutinous milled by washing, grinding, steaming, cooling and packaging. Rice cake will be continued to be a major rice product in Korea. Rice products represent a means to study variety differences in rice grain quality, since the processing magnifies differences not normally detected from more boiling. Recently, rice processing companies in Korea are about 400 ones which uses rice about 160,000tons. New rice processed products and modified traditional products must be developed and diversified with high quality and processing properties of rice processed products are improved.

This study investigated consumer perception and purchase behavior regarding Han-gwa (traditional Korean confection) in housewives residing in the Seoul and Gyeonggi area. This study was conducted by self-administered questionnaires. Out of 839 questionnaires, 713 questionnaires (85.0%) were used for statistical analyses including frequency analysis, the Chisquare, and one-way ANOVA. Based on the data collected, independence variables were divided less than 40 years (<40), 40s, 50 years or higher (50) by age. The major findings were as follows; Firstly, 72.1% of the total respondents had the experience of purchasing Han-gwa. Gangjeong was the most popular item among purchased. As the purpose of purchasing, holiday gift and snack was on the highest rank. Hypermarkets / discount stores (48.9%) was the most common place for the place of purchase. Secondly, there was a significant difference in the perception of Han-gwa by age; respondents aged 50 years or older showed more positive perception in Han-gwa in 3 factors among total of 11 factors. Thirdly, for the popularization of Han-gwa, 'too sweet taste (44.2%)' and 'small portion size (22.9%)' were pointed to be improved by respondents. Results of this study indicate that 1) Yu-gwa and Yak-gwa require new product development based on age segmentation, and health and food safety are important variables considered when housewives purchase Han-gwa.

For children's birthday 65% said preparing at home, 16.3% said no difference and 14.9% said eating out. 3. Comparing the conception on traditional food, Korean women answered 'complicated' (77%) most while 'simple' (5%) least, which indicates their demands for simplified recipes. In case of Japanese women, 'complicated' (44%) was most while 'scientific' (6%) was least which indicates their demands for scientific way of recipes. There were differences shown by age (p<0.001) and the older the more said 'simple' or 'logical' (p<0.01). 4. As the reason for the complicity of traditional food recipes, Koreans said 'too many hand skill' (60%) most while 'too many spices' (8%) least. For Japanese, 'various kind of the recipe' (55%) was most while 'too many hand skill' (7%) was least. There were significant differences shown by academic background (p<0.01) and income(p<0.01), and the lower the academic background, the more said 'too many spices' as the reason for the complicity in making traditional food. Generally, the lesser the income, the more tendency to say 'various kinds of the recipe'. 5. In case of Koreans, 'the recipe is difficult' (56%) was high while 'uninterested' (9%) was low in answer which showed differences by academic background (p<0.05), and in case of Japanese, 'no time to cook' (44%) was high while 'uninterested' (7%) was low. 6. The following is the reasons for choosing traditional food as a snack for children. In case of Koreans, they answered as 'traditional food' (34%), 'made from nutrious and quality materials' (27%), 'for education' (22%) and 'suites their taste' (17%) revealing 'traditional food' is highest.

About the consumption of traditional fermented food, Koreans said they make kimchi (90%), pickled vegetables (39%), soy sauce (33%), bean paste (38%), salted fishery (12%) and traditional liquors (14%) at home while 67% for salted fishery and 48% for traditional liquors answered they buy rather than making at home. On the other hand, Japanese answered they mostly buy kimchi (60%), soy sauce (96%), bean paste(91%), natto(92%), salt fermented fish foods (77%) and traditional alcoholic beverage (88%) to eat. This difference was shown very distinct between Korean and Japanese women (p<0.001). 10. About the most important thing in food, Koreans answered in the order of 'liking and satisfaction' (33%), 'for health' (32%), 'for relieve hunger' (18%) and 'convenience' (17%). In case of Japanese, it was revealed in the order of 'for health' (61%), 'liking and satisfaction' (20%), 'to relieve hunger' (16%) and 'convenience' (3%). This shows that Japanese women take comparably more importance to health than Korean women. The conception of food was shown different between Korean and Japanese women (p<0.001), and Koreans showed level 4-5 of food culture while Japanese showed level 5.

This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (${\geq}\;85$ percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

This study is a literature review on berries and their cooking methods that appear in ancient and modern Korean literature. Due to recent reports on berries' excellent functionality and the public's growing interest in healthy living, berries have been attracted attention as promising forms of sustenance. By structuring and classifying the types of berries and their popularity as well as recipes using berries found in ancient and modern Korean literature, this review hopes to serve as an important source that reflects both the food culture and social aspects associated with the value of berries in the lives of Korean people as well as foster understanding of the superiority of Korean food culture. This study will also have implications on the possibility of integrating antioxidant-rich berries into the modern food landscape. The study results are summarized as follows. Types of berries were classified into six types (Korean cherry, Omija, Gugija, Bokbunja, Black cherry, Mulberry) while cooking methods were classified into five types (Korean traditional snack, Korean traditional beverage, Liquors, Porridge, Pilule) in the ancient and modern literature of Korea. The aim of this literature review is to highlight the value-creating aspect of berries as food materials that can yield high added-value products. Beyond their value as healthy fruits, this study will explore the features of berries that enhance their added value and brand marketing as well as their aspects suitable for application to the modern industry of berry product development.

Eumsikjeoljo (integrity with food) originally came from the Andong district, where the Goseong Yi clan inherited a cookbook from their ancestor Lee Jeong-Rong (1798~1871). The cookbook was written in an antiquated style and is estimated to have been written around the year 1865. Details of the era and authorship are seldom available for the extant ancient cookbooks. The authors of these books and the period during which these books were precisely written were studied through the Eumsikjeoljo which is a repository of 46 cooking disciplines. Of these 10 deal with the practice of traditional Korean crispy snack making, 4 with rice cake making, 3 of the yeonbyeong kind, 19 examples of Korean side dish making, 6 recipes of the kimchi variety, 2 examples of paste-based recipes, and 2 instances of instructions on how to make vinegar-based extracts. Also, in Eumsikjeoljo, there are descriptions of 29 different ways to brew rice wine. Of these, Danyang wine among the Leehwa wines and 13 others account for over 44% of the content. Leeyang wine and Sogok wine are represented by 10 different varieties and constitute around 34% of the entries. Samyang wine and Baek-il wine, along with 6 others, constitute 21% of the entries. The secret recipes of the Goseong Yi clan in the Andong district were recorded so that they could be transferred to the descendants of the clan. An inspection of the recipes and wine brewing techniques recorded in Eumsikjeoljo provides a clearer picture of the mid-1800s Andong noble family's traditional food habits and simultaneously sheds light on the late Joseon dynasty's food culture.

The objective of the study was to define dietary patterns in the representative Korean adult population and to explore their associations with other factors. The Korean National Health and Nutrition Survey was conducted on a stratified random sample (n = 9,968) of the Korean population in 2001. This study analyzed data of 5,721 adult population aged 30 and over. Demographic and lifestyle factors were assessed by questionnaires and food consumption by a 24-h recall method. Cluster analysis identified two dietary patterns with 22 food groups: the larger group that included $85\%$ of total subjects was named as the 'traditional' pattern due to greater intakes of white rice, kimchi, and vegetables, and the smaller group was named as the 'modified' pattern which had greater intakes of noodles, bread, snack, and fast foods. The modified pattern had significantly higher proportion in younger age, higher educational level, residing in metropolitan area, and higher household income. The modified group showed significantly higher intake of all nutrients except carbohydrate. Percent of energy from fat intake, $22\%$ was significantly higher in the modified group than $14\%$ in the traditional group. There were no differences in prevalence of metabolic syndrome and its 5 components among patterns. In conclusion, there were two distinctive patterns that were associated with socio-demographic, nutrient intake, and health risk factors in Korea. It should be considered when designing nutrition policy and intervention program.

BACKGROUND/OBJECTIVES: Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS: We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS: Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS: These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

A survey was conducted of 1,454 customers to investigate dining out behaviors at fast food restaurants of Youido department compound, Myung-dong and Gang-nam district in Seoul, in April, 1988. The results are summarized as follows; The majority, 85% of customers, were aged 14 to 30, consisting of junior and senior high school children, college students and company employees. The reasons given by customers for patronizing fast food restaurants were the following, from most to least frequent; "convenient to dining," "the adequate place for the companionship", "the surroundings and dining equipment are pleasant and hygienic", "to be able to stay as long as I want". The fast foods purchased by the customers were mostly for a between meal snack or ice cream or drink rather than a full meal. The majority of the customers ate the purchased foods at the fast food restaurnats. However, a limited number of female customers preferred to take the packed fast foods to their homes. Tast Preference was a major factor in food selection from available food items. Ice cream, juice, French fried potatoes, salad, fried chicken, rolled rice with laver, and coke were high on the list of liked foods; in constrast, lower preference was for porridge, fish burger, doughnut, chicken burger and rice cake. Preference by food nationality was highest for Korean food, then Western food, Chinese food, Italian food and Japanse food, in that order. Customers offered suggestions for better fast food service, such as lowering the price, greater variety in the menu, increasing the propotion of vegetables and fruits on the fast food menu adn developing fast foods from traditional Korean foods. The customers, in particular, emphasized a need for the development of Korean traditional beverage of malted drink and persimmon punch, as well as mungbean pan cakes and sweet-spicy rice noodles(docbokki), as fast foods.y rice noodles(docbokki), as fast foods.
