Purpose: The purpose of this study is to analyze nutrient intake and frequently consumed foods according to the intake frequency of Baechu (Chinese cabbage) kimchi by Korean adults. Methods: Data from analysis of 7,122 subjects aged 19~64 years from 2012, 2013 KNHANES were obtained from health behavior interviews and the 24-hour dietary recall method. Results: With the daily intake frequency of Baechu kimchi, subjects with two times a day were the highest proportion among total subjects. As Baechu kimchi intake frequency of breakfast, lunch, and dinner increased, the rate of skipping meals decreased significantly (p < 0.05). In addition, all food intake and daily nutrient intake increased significantly with increasing frequency of daily Baechu kimchi intake (Crude p for trend < 0.05, Adjusted p for trend < 0.05). With the frequently consumed foods by daily Baechu kimchi intake frequency in 2012 and 2013, among 509 foods top ranked foods were white rice, Baechu kimchi, beer, distilled alcoholic drink, milk, and pork. Conclusion: The results of this study could be used in the future to promote consumption of kimchi in the Korean population.

The intake patterns and attitudes towards development of functional kimchi among middle and high school students in Busan area were studied. Nine hundred respondents, consisting of middle and high school students, were surveyed. A total of 833 completed copies of the questionnaire were used in this research. Respondents preferred kimchi due to its 'ot taste' (49.2%) and 'alty taste' (17.9%), but they did not like kimchi due to its 'our taste' (33.8%) and 'eotgal taste' (22.9%). Most students (64.3%) consumed kimchi at home, 68.1% of students ate kimchi more than twice a day, and 27.4% of students consumed 3~4 pieces (size of a piece: $3{\timess}4cm$) of kimchi per meal. Students showed a strong desire to develop kimchi with a good taste at school food services (65.1%). They also showed intentions to increase intake of kimchi if 'aste of kimchi' (80.6%), and 'ealth functionality of kimchi' (65.2%) are strengthened. Students wanted kimchi to contain the following fruits: pears (41.3%), apples (24.6%) and pineapples (10.3%). Finally, students showed a desire to develop kimchi that helps growth and development (59.5%), weight loss (40.4%), and learning ability improvement (32.8%). This study concludes that it is necessary to increase kimchi intake in school foodservices by developing new kimchi recipes that meet students' desires and by educating students about the health benefits of kimchi.

This study investigated the preference, intake condition and awareness of Kimchi of 660 elementary students in the Seoul area surveyed during June, 2008. The preference test was performed by using 5-point hedonic scale (1=dislike very much, 5=like very much). The most preferred types of Kimchi were Baechukimchi (4.32), Bossamkimchi (4.08) and Kkakdugi (4,01). The most preferred foods prepared with Kimchi were Kimchi jjige (4.59), Kimchi bokkeumbap (4.47), fried Kimchi (4.35), Kimchi pancake (4,31), Kimchi mandu (4.20) and Kimchi kimbap (4.06). Kimchi pizza (2.88), Kimchi hamburger (2.85) and Kimchi spaghetti (2.81) were not preferred. Most students (62.7%) ate Kimchi at almost every meal. The main reason for eating Kimchi was its delicious taste (50.3%). Concerning intake of Kimchi provided at school lunch, 48.4% of students ate some, 45.9% ate all and 5.8% ate none. Various kinds of Kimchi should be developed for elementary school students to meet their taste.

This experimental study was carried out to evaluate the effects of Kimchi intake of Cordyceps sinensis extract (CDSE) supplementation on cytokine-induction and immune response in mice. To study in experiments using male Balb/c mice fed Kimchi and Kimchi of CDSE supplementation (addition of 2% of total Kimchi weight) containing fed experimental diet during 2 weeks. Experimental mice were fed control diet or diet containing freeze-dried Kimchi at the level of 5%(w/w) or 5% freeze-dried Kimchi with 2% CDSE supplementation. The main ingredient of Kimchi was Korean cabbage and fermentation was carried out at $4^{\circ}C$ for three weeks. Freeze-dried 2% CDSE supplementation was added to Kimchi at the beginning of fennentation. In order to investigate the effect of Kimchi intake of CDSE supplementation (5%Kimchi-2%CDSE), the following was performed; body weight, food intake, hematological parameter, serum level of mouse interleukin-4 (mIL-4) and mouse $interferon-{\gamma}$ $(mIFN-{\gamma})$, and, the percentage of CD3+/CD4+, CD3+/CD8+, B220+ in splenic cells. The results of final body weight, and food diet intake of two Kimchi groups were lower than those of the control group (not supplemented experimental diet). The hematology change obtained from the level of WBC (white blood cell) and platelet were not affected by feeding different dietary regiments, but the level of RBC (red blood cells) HB (hemoglobin), and spleen weight of two Kimchi groups were increased significantly than those of the control group. The serum level of IL-4 and $IFN-{\gamma}$ of two Kimchi groups were increased significantly than those of the control group, also enhanced the percentages of the CD3+/CD4+ and CD3+/CD8+ by 5% freeze-dried Kimchi, and 5%Kimchi-2%CDSE group were 43.9 and 60.1%, and 96.0 and 174% than those of the control group, respectively. From these results, it can be concluded that Kimchi itself has an immuno-stimulatory effect and Kimchi contaning 2% CDSE supplementation has the more pronounced effect in vivo system.

This study aims to find out the devices to minimize the amount of nitrate ingested from kimchi, the main way of vegetable intake for Koreans, and the basic data to deliver to calculate the total daily intake for Korean, investigating the year-round changes of nitrate content in vegetables for Kimche raw material, and changes of nitrate content by salting of chinese cabbage, and stewed kimchi through the use of different cooking methods. The results obtained were summarized as follow: over between 205-6655mg/kg f.w. in chinese cabbage, 480-3970mg/kg f.w. in chinese radish, 157-5820mg/kg f.w. in lettuce and 29-520mg/kg f.w. in cucumber respectively. Therefore it was strongly adviced to introduce the nitrate limit value of vegetables in Korea if the nitrate content in Kimchi should be reduced to meet the nitrate ADI(Acceptable Daily Intake, 219mg60kg b.w) of FAO.WHO, because the nitrate content in Kimchi reflects the nitrate content in vegetables. In order to keep the low nitrate content in Kimchi. it was adviced to remove the outer leaf which contains 2-3 times higher nitrate content compare to the inner leaf at the time of preparation, i.e. chinese cabbage, before the soaking treatment in salt solution for Kimchi making process. The dehydration by soaking treatment in salt solution occurred at 0.9%~4.7% in leaf midrib and more than 13%~24% in leaf blade. The nitrate content after soaking in salt solution was increased 107%~123% compared with before soaking, increasing rates of nitrate content in the outer and inner leaf midrib were higher than those in leaf blade. The increase of nitrate content in salt solution after soaking due to the dehydration of chinese cabbage by soaking treatment. The Kimchi stew(Kimchi JJige) was processed with and without animal oil, but the amount of nitrate in kimchi stew did not decrease both treatments, but it increased after the processing since the water in Kimchi stew has got low by boiling.

Kimchi is the most well-known Korean traditional food, but it is also the main leftover of school lunch and dinner menus. This study aimed to familiarize teenagers with kimchi through school meals and to increase their daily kimchi intake, ultimately by appealing to the young generation's taste. A questionnaire survey was conducted in the Ansan area to examine student's acceptability of kimchi and their attitudes toward kimchi. Approximately 65% of males and 67% of female students liked the moderately fermented and pungent taste of kimchi. Kimchi served in school meals was regarded as nutritional but cheap. Approximately 72% of male and 82% of female students responded that they liked menu items using kimchi. Approximately 48% of students responded that menu items using kimchi in schools are not diverse. Students preferred meat as an ingredient in kimchi. The preferred cooking methods were stir-frying and frying, whereas boiling was the least favorite. Based on the survey results, ten kimchi menu items had been developed. The suitability of the menu was evaluated by students and cooks. Six kimchi items, including Kimchi mixed with rice, chicken, soybean sprouts, Kimchi cheese rice, stewed beef ribs with kimchi, rice topped with kimchi curry, kimchi cheese meat roast, and kimchi udong were considered appropriate for school meals, whereas kimchi kangchong, kimchi topokki, kimchi stew with surimi, and frozen Pollack kimchi soup were not suitable as menu items. Kimchi topokki was not accepted by students, while kimchi kangchong was not accepted by cooks. Cooks judged the suitability of a menu item by the cooking process and cooking times, whereas students judged an item by its sensory preference. Approximately 63% of students responded that kimchi intake has increased by participating in the development of kimchi dishes.

This study was carried out to investigate the intake pattern and the experience on the kimchi-making, and to analyze the taste preference of kimchi. The questionnaires have been collected from 473 college students in Taejon. Most students had taken baechu-kimchi, kkakduki, yeolmu-kimchi, dongchimi, and cheonggak-kimchi. They liked baechu-kimchi best, and then cheonggak-kimchi. Twenty-seven percent of students took kimchi every meal time and 53 % once a day. The rest 19.4% replied that they could take meals without kimchi. The male students ate more kimchi than the female(p<0.01). Sixty-five percent of them had tried the foreign foods made with kimchi and female had more experience than male(p<0.01). The taste of kimchi-japchae and kimchi-woodong was indicated as edible or taste very good by over two thirds of the students. Kimchi-pizza, kimchi-hamburger, and kimchi-spaghetti were evaluated as edible or taste good by the over half. The aging of kimchi was believed to be the most important factor to determine the taste. Students preferred kimchi which was weak in salty, sweet, and jot-kal taste, strong in hot taste, and proper in sour taste(well-fermented). Compared with the male, the female enjoyed kimchi having stronger sour and weaker jot-kal taste(p<0.01). More female students(43.5%) had experenced kimchi-making than the male(26.5%)(p<0.001). Three-fourth of them had made kimchi with their mother. Baechu-kimchi, cheonggak-kimchi, and dongchimi were recommended as the global food.

The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well as analyze the differences by gender among fourth to sixth grade students (n=410) in a Chungnam region. Approximately 64% of the students liked the spicy taste of kimchi, 75.9% liked the saltiness, and 48.5% liked well-fermented kimchi. The disliking factors of kimchi were its sour taste (38.5%), strong scent (20.1%), and salty taste (15.4%). The most preferred type of kimchi was Baechukimchi, followed by Kkakduki, Yeolmukimchi, and Chonggakkimchi. Further, the most frequently consumed type of kimchi was Baechukimchi, followed by Kkakduki, Chonggakkimchi and Yeolmukimchi. Oisobaki, welsh onion kimchi, sesame leaf kimchi, Gatkimchi, Nabakkimchi and Baekkimchi were rarely consumed. About 34% of the students consumed 5 to 7 pieces of kimchi per meal, and 84.1% enjoyed eating kimchi, mostly because of its good taste (61.3%). The reason for not eating kimchi was because other side dishes are more delicious (30.2%). About 80% of the students responded that they prepared kimchi at home. Moreover, 74.3% of the students eat kimchi much more at home than at school. Improvements to be made for kimchi at school were as follows: less salty (34.9%), less spicy (27.6%), and sweet (22.5%). In conclusion, students enjoyed eating kimchi because of its good taste. Further, they showed preference for Baechukimchi, Kkakduki, and Yeolmukimchi and consumed them frequently. Because kimchi appears to be more preferred and more frequently consumed, it is necessary to develop a menu using kimchi along with the proper eating guidance for helping students consume various types of kimchi at school or at home.

The purpose of this study was to evaluate the daily vegetable and fruit intake status of Korean adults and to examine the relationship of vegetable and fruit intake with bone metabolism. The vegetable and fruit intake of 542 healthy male and female adults was analyzed. Then, by selecting 51 targets from the subjects, the relation of vegetable and fruit intake with serum calcium, osteocalcin and deoxypyridinoline (DPD) excretion in urine was examined. The total vegetable intake per day was 397.7 g and 333.5 g by men and women respectively for the age group of 20-29, 366.9 g and 309.2 g respectively for the age group of 30-49, 378.4 g and 325.9 g respectively for the age group of 50-64. Of vegetable varieties, leafy and stem vegetables displayed the highest intake. The order of major intake items of vegetables and fruits was found to be Chinese cabbage kimchi, onion, radish, cucumber, and welsh onion for the age group of 20-29, watermelon, Chinese cabbage kimchi, peach, potato, and onion for the age group of 30-49 and watermelon, Chinese cabbage kimchi, tomato, potato, and peach for the age group of 50-64. Of 51 targets, ${\beta}$-carotene intake displayed a significantly negative correlation with serum osteocalcin. While caloric intake as well as protein, carbohydrate, calcium, phosphorous, zinc and total food intake displayed a significantly negative correlation with DPD excretion in urine, tuber vegetable intake displayed a significantly positive correlation with DPD excretion in urine. In the future, a study will be necessary to accurately explain the relevance of vegetable and fruit intake with bone mineral density and bone metabolism. Also, efforts will be required to increase vegetable and fruit intake.
