This study was performed to investigate the dietary habits and satisfaction of school foodservice by high school type (academic high school students (AHSS) : n=200, vocational high school students (VHSS) : n=200). Frequency of skipping breakfast was significantly higher for VHSS compared with AHSS (p<0.001), and reasons for skipping breakfast were significantly high for 'lack of time' and 'habitually' in VHSS (p<0.01). Duration of mealtime was significantly higher for AHSS compared with VHSS (p<0.001). Frequency of snacking was high in both AHSS and VHSS, and after dinner was the most common snack time for AHSS (p<0.001). Most commonly cited methods for improving dietary habits were 'frequently skipping meals' in AHSS and 'irregular meals' in VHSS. Reasons for leaving leftover foods were 'no taste' in AHSS and 'side dish I don't like' in VHSS (p<0.05). Satisfaction of school foodservice was significantly higher for AHSS compared with VHSS (p<0.05). Most commonly cited methods for improving school foodservice were 'varied menu' in AHSS and 'food taste' in VHSS (p<0.05). Commonly cited dietary motivations were 'preference' in AHSS and 'resolving starvation' in VHSS (p<0.001). As preference is an important factor, new menu development and continuous nutritional education should be necessary for menu diversity in order to raise satisfaction by using foods with high preference and superior nutrition.

Objectives: The study was performed to examine the dietary behaviors and life stress of middle school students in the Gyeonggi area. Methods: A total of 580 middle school students (295 males, 285 females) in the Gyeonggi area participated in the study between July and August in 2011. The study was a questionnaire-based survey that included dietary habits, dietary behaviors, and life stress. Results: For dietary habits, the score for drinking milk was higher in male students than in female students, whereas the score for eating fruits was higher in female students compared to male students. There were significant differences in foods eaten and preferred under stress between male and female students. Male students showed significantly less changes in the number of meals, amount of meal intake, number of snacks, snack intake, frequency of overeating, and appetite during stress than female students. Life stress score of students largely came from academic factors, and female students showed higher stress levels in personal and surrounding environment factors than male students. Life stress score was significantly lower in students with high and moderate levels of dietary habits than in students with a low level of dietary habits. Total score for dietary habits and scores for eating adequate amounts of foods for each meal, considering a combination of food groups at each meal and eating green and orange vegetables, were significantly negatively correlated with life stress score. Life stress score was significantly negatively correlated with meal regularity and positively with the level of overeating. Conclusions: This study may provide basic information on dietary habits and life stress according to gender and the relationship between dietary behaviors and life stress of middle school students, and it suggests gender-based nutrition education programs to solve undesirable dietary habits and dietary behaviors in students with higher stress.

The purpose of this study was to implement and evaluate the nutrition education program for elementary school children Subjects were 5th graders (n = 142) of an elementary school in Seoul, and 138 children completed four sessions of nutrition education during March-April, 2008. One group pretest-posttest design was used to evaluate the program effectiveness. Anthropometric measurements and measurements on nutrition knowledge, eating attitudes and eating behavior were done before and after education. Data were analyzed using paired t-test, t-test and ${\chi}^2-test$. After completing nutrition education, body mass index (from 19.3 to 18.9), fat mass (from 10.9 kg to 10.1 kg), percent body fat (from 25% to 23.3%) of subjects decreased significantly (p < 0.001). Percentages of overweight or obese children were 24.6% at pretest and decreased to 20.3% at posttest, although it did not reach statistical significance. Total score of nutrition knowledge increased significantly from 11.9 (59.5/100) at pretest to 14.7 (73.5/100) at posttest (p < 0.001). After nutrition education, percentages of correct answers increased significantly in 10 knowledge items out of 20 items. These included items such as desirable weight control, energy requirements for boys, food groups, snack, and function of fat and balanced meals (p < 0.001). Total score of eating attitudes increased significantly from 35.1 to 36.9 (p < 0.001). Attitude of applying nutrition knowledge to daily life (p < 0.001), interest toward nutrition and health (p < 0.001), attitude of moderating food intake (p < 0.01), and attitude toward eating habit and future health (p < 0.05) were significantly different between pretest and posttest. Total score of eating behaviors increased significantly from 46.7 (possible score: 20-60) to 49.5 by nutrition education (p < 0.001). Improvement in eight eating behaviors were noticed after nutrition education. These included eating meals slowly, eat protein foods (p < 0.001), eating breakfast, eating meals regularly, eating meals with diverse foods, having dairy foods, eating foods using plant oils (p < 0.01), and having grains (p < 0.05). Subjects evaluated quite positively in attractiveness of program, understanding of program contents, helpfulness of program in improving nutrition knowledge and meal management. Study results show that the nutrition education program was effective in improving nutrition knowledge, eating attitudes and changing eating behaviors of children. This program can be used in nutrition education of children at school or at public health centers.

This study was performed to investigate patterns of fortified food (FF) consumption and intake of vitamins and minerals from FFs among 577 Korean children (12.4 years of age) who attended elementary or middle school. FFs eaten by children as a snack were surveyed using the food record method during 3 days, including 2 week days and one weekend. As a result, 114 FF items were eaten by the children, and several kinds of nutrients such as vitamin A, D, E, B complex, C, calcium (Ca), iron (Fe), and zinc (Zn) were fortified in these foods. Ca-FFs (65.8%) were most frequently consumed, followed by vitamin C-FFs (33.4%) and vitamin D-FFs (33.3%). The number of FF items in each food group was the most in the milk group (n=24, 21.0%), followed by the beverage group (n=19, 16.7%), and the cookie/bread/cake group (n=17, 14.9%). Fortified nutrients in FFs were in various combinations, but the major combination patterns were Ca, Ca plus vitamins, Ca plus vitamins plus other minerals, and Ca plus other minerals. Daily mean intakes of vitamins and minerals from the FFs were 66-300% more than those of the recommended nutrient intake (RNI ) or adequate intake (AI) for most vitamins and minerals. Daily maximum intakes (95th percentile) of vitamins and minerals from FFs were 1-15 times the RNI or AI for most vitamins and minerals. Vitamin and mineral consumption ratios from each FF group were different according to the kind of fortified nutrient. For example, vitamin C was mostly eaten in fortified beverages (46-54%), and Fe was mostly eaten in fortified cookie/breads/cakes (87%). The above results show that FF consumption varied widely among the children, and that most of the children's foods were fortified with several vitamins and minerals without a common rule; thus, subjects risked over consuming vitamins and minerals by eating FFs. Therefore, practical guideline on FF use for children's optimal nutrition and health should be provided through nutrition education.

This study was based on the information provided by 1,180 elementary school children (630 boys and 550 girls) of 5th or 6th grade in Changwon and Gimhae of Gyeongnam province. They were asked about perception and preference for rice foods by questionnaires. The purpose of this survey was to find the way of encouraging rice intake and preference which is currently getting lower because of increasing simple westernized eating habits, and to provide basic information needed for inheriting and improving our traditional rice-based dietary culture. The results are summarized as follows. Most of subjects (91.2%) thought that steamed rice is better than bread for own health. The reason why they chose to eat steamed rice was 'because it is good for health' (61.2%), and 'because it is staple food item that we eat everyday' (26.4%). Seventy one percent of girls and 52.7% of boys gave the answer 'because it is good for health' as the reason for eating steamed rice. The reasons for the importance of the rice-based dietary culture were 'because of its superior nutritional value' (40.8%), and 'because it is our traditional eating culture' (28.6%). While significantly more girls (42.9%) answered as 'because of its superior nutritional value', more boys (39.0%) answered as 'because it is our traditional dietary culture'. More boys (59.0%) preferred noodles than girls' (54.7%), and fruits were preferred more by girls than boys as substitution foods for steamed rice showing significant difference (p<0.01). They wanted rice product developed in the forms such as Ssalamyun (29.8%), Ssalmandoo (24.1%), rice noodles (20.6%), and rice bread (15.6%). The preference score on rice products of subjects was one dish meals (4.27) and drinks (4.26), snacks (3.72), convenience foods (3.61), and steamed rice (3.44) in order. Preferred food showing points over 4 were Ssalbap (plain steamed rice) (4.29) in steamed rice type food, Kimchi bokeumbap (4.56), Bokeumbap (4.55), Bibimbop (4.45), Omelet rice (4.44), Kimbap (4.42), Ddukkuk (4.33), Curried rice (4.33), Jajangbap (4.28), and Ddukmandookuk (4.24) in one dish meal type food, Samgak Kimbap (4.26) in convenience type food, Songpyun (4.48), Injulmi (4.18), Teokbokki (4.71), Ddukkochiguyi (4.46), and rice cookies (4.24) in snack type food, and Shikhye (4.61) and Misugaru (4.28) in drink type food. Based on these results, it may be said that elementary school children think the rice-based diet is good for health and this dietary culture should be inherited and developed not only in a traditional aspect but also in a nutritional aspect. Therefore, more studies are needed to develop various forms of rice food products and cooking recipes.

This study was designed to examine nutrition label use, self-efficacy, snacking and eating behaviors of middle school students, and to investigate if these characteristics were different by nutrition label use. A cross-sectional survey was conducted to 348 middle school students in Kyunggi, Korea. About a third of subjects read nutrition labels when they purchased snacks/packaged foods. Most nutrition label users were interested in reading information on calories, fat and trans-fat. Self-efficacy of eating/selecting snacks or general nutrition behavior was moderate (mean score: 44.4 out of 60), with significantly higher score in nutrition label users compared to nonusers (p < 0.001). Nutrition label users felt more confident in 9 items out of 15 items of self-efficacy, such as "taking fruits instead of cookies/candy for snack" (p < 0.001), "choosing milk instead of soft drink" (p < 0.01), "not having snacks after dinner" and "avoiding processed foods for snacks" (p < 0.05). Subjects had snacks 1.3 times a day, and nutrition label nonusers consumed snacks more frequently than the counterparts (p < 0.01). About 55% of nutrition label users and 64.7% of nonusers mainly purchased snacks for themselves (p < 0.05). Commonly purchased snacks by adolescents were ice cream, cookies/chips, breads and ramen. Major considerations in purchasing snacks were taste (46.9%) and price (34.6%). In selecting snacks, the influence of friends and parents was greater than the other sources. Based on eating frequency of snacks, nutrition label users were more likely to consume healthy snacks, such as fruit juices, vegetables, milk, yogurt, and potato/sweet potato than nonusers (p < 0.05). Eating behaviors measured by 15 items scored 33.6 out of 45. Nutrition label users showed better eating behaviors, such as "eating meals slowly", "eating foods cooked with plant oil", and "eating out less frequently" (p < 0.05). Study results showed that majority of adolescents did not read nutrition labels, selected snacks for themselves and had somewhat unhealthy foods for snacks. This study also showed the differences in self-efficacy, snacking and eating behaviors between nutrition label users and nonusers. In nutrition education, it is necessary to stress the importance and skills for reading nutrition labels. It is also needed to help adolescents to select healthy snacks and have desirable eating behaviors, as well as increasing self-efficacy.

Enzyme-linked fluorescent immunoassay(ELFA)를 이용하여 가공식품 중 땅콩을 분석하고, 그 결과가 표시내용과 일치하는지를 조사하였다. 땅콩으로부터 분리한 조단백질(CPP)을 토끼에게 면역하여 생산한 특이항체 및 horseradish peroxidase-항체 복합물을 이용하여 sandwich ELFA를 확립하였다. 특이항체의 교차반응은, CPP, 땅콩, 아몬드, 콩, 호도에 대하여 각각 100, 9.8, $1.1{\times}10^{-2},\;4.4{\times}10^{-3}$, 0%로 나타났다. 시료로는 비스킷, 스낵, 초콜릿 등 19점을 사용하였다. 이들의 분석결과, 7점의 시료에서 땅콩이 검출 되었으며, 이 중 땅콩의 함유가 표시된 제품은 5점이었고 그렇지 않은 제품은 2점이었다. 이들 2점 중 하나는 아몬드를 함유하고 있다고 표시된 비스킷으로 분석 상 미량($2.1{\times}10^{-3}%$)의 땅콩이 검출되었는데, 이는 교차반응 때문으로 추측된다. 나머지 1점은 대두의 함유가 표시된 스낵으로 분석 상 $9.8{\times}10^{-2}%$의 땅콩이 검출되었다. 이는 대두의 매우 낮은 교차반응율을 감안하면 제조공정상 땅콩의 교차오염 때문으로 추측된다. 이와 같이 ELFA에 의하여 가공식품 중 땅콩의 검출이 가능하였고, 현재 유통 되는 일부 가공식품 중 알레르겐의 표시를 정확히 할 필요가 있다고 생각한다.
