In order to improve the Quality of university foodservice, use and satisfaction with five cafeterias among students in a university located in Cheongju were evaluated by a Questionnaire survey. The results analyzed from the responses of 673 students are as follows: Students who usually eat at the cafeterias were 4.4% for breakfast, 81.5% for lunch. and 27.8% for dinner. Fifty one percent of the students ate at the' cafeterias once a day, and 26.6% more than twice a day. The main reasons for eating there were 'to save money and time' and 'no other appropriate place to eat'. The reasons for not eating there were 'tasteless', 'crowded and noisy', and 'waiting in a long line', The mean satisfaction scores for taste, menu, and sanitary conditions of cafeteria were the lowest at Cafeteria A, which is directly managed by the university. The scores for price and the amount of food, the degree of keeping warm of food, kindness of the personnel, and cleanliness of dishes and spoons were the lowest at Cafeteria E, which is managed by a private enterprise. While male students were more dissatisfied with the amount of food, especially rice, female students were more dissatisfied with the degree of keeping warm of food, kindness of the personnel, and sanitary conditions of cafeterias. The first priority each cafeteria should improve was found to be taste of food at Cafeteria A and C, price at Cafeteria Band E, and menu and taste at Cafeteria D. These results showed that the students were very dissatisfied with the foodservice offered at the cafeterias and eager for the improvement of the quality. It is anticipated that those who take charge of the management of the cafeterias will make efforts to improve the quality of foodservice on the basis of these results.

  A book with nutrition theme can be used as an interesting tool to teach nutrition to children. The purpose of the study was to search children"s books with nutrition themes, and evaluate the content and the quality of the books. Fifteen books were found on the internet and in a bookstore. The main subjects were cooking (8 books), weight control (5 books), and food culture (2 books). Most books regarding cooking provides recipes but they do not provide enough information on food groups, nutrients, and food sanitation. Most books regarding weight control provides desirable food habits, calories in foods, and excercise, but they need to give more information on appropriate method to assess children"s obesity. Most books were evaluated as "The messeges were clear." "The illustration matched with the theme." "The illustration was attractive." However, most books were not written by a nutrition professional, indicating the reliability of the books was not ensured. Therefore, more books with various nutrition themes should be written for children by nutrition professionals, which can be used to help children develop healthy eating behavior.

패스트푸드와 가공식품의 엽산 함량

지현정(Ji Hyun Jung),김승기(Kim Seungki),연미영(Yon Miyong),현태선(Hyun Taisun) 韓國營養學會 2009 Journal of Nutrition and Health Vol.42 No.4

본 연구에서는 식품 중의 엽산을 추출하기 위한 trienzyme 방법을 개선하기 위하여 α-amylase와 folate conjugase 를 동시에 처리하는 방법 (CI)과 기존의 방법대로 protease, α-amylase, folate conjugase 세가지 효소를 각각 처리하는 방법 (SI)을 비교해 보았으며, 개선된 방법을 이용하여 패스트푸드와 가공식품에 들어있는 엽산 함량을 분석하였다. 1) 12종 88개 식품에 대하여 엽산을 추출하기 위한 기존의 방법 (SI)과 두가지 효소를 동시에 처리하는 CI 방법으로 엽산 함량을 비교한 결과 식품의 종류에 따라 두 방법간에 -6.5%에서 34.0%까지의 차이를 보였다. 식품의 종류별로 paired t-test를 한 결과 9종에서는 유의적 차이를 볼 수 없었으며, 3종에서는 CI 방법이 SI 방법에 비해 유의적으로 높은 것으로 나타났다. 이는 효소 처리시간이 단축됨으로 인해 엽산의 손실이 적었기 때문인 것으로 보이며, 따라서 실험시간을 절약할 수 있는 CI 방법을 활용하는 것이 바람직하겠다. 2) CI 방법으로 식품 중의 엽산을 추출하고 미생물학적 방법으로 엽산 함량을 분석한 결과 햄버거의 100 g당 평균 엽산 함량은 29.0 ㎍, 치즈버거 35.6 ㎍, 불고기버거 34.4 ㎍, 새우버거 33.5 ㎍, 치킨버거 29.3 ㎍, 휘시버거 31.7 ㎍이었다. 비스킷의 엽산 함량은 28.1 ㎍, 감자튀김은 49.1 ㎍이었고, 피자 29.7 ㎍, 샌드위치 31.6 ㎍, 삼각김밥 24.3 ㎍으로 나타났으며, 이 값을 1회 분량으로 환산하면 버거종류는 43.1~62.0 ㎍, 감자튀김 53.3 ㎍, 피자 28.4 ㎍, 샌드위치 47.4 ㎍, 삼각김밥 25.7 ㎍이었다. 3) 가공식품 26종의 엽산함량을 측정한 결과 100 g 당엽산 함량이 가장 높은 식품은 캔옥수수로 89.5 ㎍이었고 다음으로는 냉동만두가 80.8 ㎍이었다. 그 외의 가공식품으로 소시지는 19.6 ㎍, 비엔나소시지 11.7 ㎍, 햄 11.5 ㎍, 튀긴어묵 10.7 ㎍ 등으로 측정되어 가공식품의 엽산 함량은 대체로 낮은 수준이었으며, 음료의 엽산 함량은 100 g당 1.0~5.2 ㎍으로 매우 낮았다. 4) 본 연구에서 분석한 패스트푸드와 가공식품, 소스, 음료 등 32종의 엽산 함량을 기존의 식품영양가표와 비교하였을 때 식품영양가표의 엽산값은 분석값과 비슷한 경우도 있었으나 0.04~140배 까지 차이가 매우 큰 경우도 있었다. 본 연구에서 분석한 식품 중의 엽산 함량은 우리나라 사람들의 엽산 섭취량을 파악하고자 할 때 기초자료로 활용될 수 있을 것이며, 어린이, 청소년, 젊은 성인층에서 섭취량이 점차 증가하고 있는 패스트푸드와 새롭게 개발되는 가공식품의 엽산 함량을 앞으로도 지속적으로 분석하여 이를 데이터베이스에 반영할 필요가 있다고 여겨진다. A trienzyme extraction method (use of α-amylase, protease and folate conjugase) for food folate assay has been used to release folate from the food matrix. In order to reduce the incubation time with three enzymes, folate values were compared between two incubation protocols; separate incubation (SI, incubated with α-amylase and conjugase separately for 2 hours after protease treatment) and combined incubation (CI, incubated with α-amylase and conjugase together for 2 hours after protease treatment) using 88 food items from 12 kinds of fast foods and processed foods. We found that folate values by CI were comparable to or higher than those by SI, indicating that CI might be a better extraction procedure to shorten the entire incubation time. We measured folate contents in 49 fast foods and 26 processed foods by microbiological assay after CI. Mean folate contents of one serving of various burgers ranged from 43.1 to 62.0 ㎍. One serving of French fries, pizza, sandwich and triangled kimbab contained a mean of 53.3, 28.4, 47.4, and 25.7 ㎍ of folate, respectively. Folate contents of non-alcoholic beverages were very low, ranging from 1.0 to 5.2 ㎍/100 g. Some of our values were comparable to the values in the folate database published in Korean Nutrition Society, however, some of the published values were 140 times higher than the measured values in this study. Folate values measured by the more recent modifications here can be used to update Korean folate database to accurately estimate dietary folate intake

This study was conducted to develop nutrition education using world cafe and brain writing and to investigate the effects of self-efficacy and attitudes toward vegetable intake among elementary school students. Nutrition education was implemented for sixth-graders in elementary school (45 children in the education group, 50 in the control group). Self-efficacy and attitudes toward vegetable intake of elementary school students were compared between the groups before and after the educational intervention. A personal activity sheet and a group activity sheet for nutrition education were developed. A personal activity sheet included vegetable bingo (one-line bingo), vegetable intake assessment, and a pledge to increase vegetable intake (1-min paper). A group activity sheet was developed based on the concept of world cafe and brain writing to improve creative thinking, information processing and communication skills. The nutrition education, which was developed as nine steps based on the concept of world cafe and brain writing, was implemented with the education group. After the nutrition education, children in the education group demonstrated significant improvements in self-efficacy and attitudes toward vegetable intake compared with children in the control group. The nutrition education using world cafe and brain writing developed in this study is expected to be applied to various nutrition education topics.

초등학생의 미량영양소 섭취부족 위험 진단을 위한 간이 식습관평가표 개발

연미영(Yon Miyong),현태선(Hyun Taisun) 韓國營養學會 2009 Journal of Nutrition and Health Vol.42 No.1

초등학교 4~6학년 어린이 142명 (남 80명, 여 62명)을 대상으로 식습관과 식이섭취조사를 실시하여 미량영양소 섭취부족의 위험이 있는 어린이를 선별할 수 있는 간단한 식습관평가표를 개발한 결과는 다음과 같다. 미량영양소 섭취부족 위험지표는 비타민 A, 리보플라빈, 비타민 C, 칼슘, 철분, 아연의 여섯가지 영양소에 대하여 권장섭취량에 대한 섭취 백분율과 평균 적정섭취비율 (MAR), 이들 여섯가지 영양소 중 평균필요량 미만으로 섭취한 영양소의 개수를 임의로 선정하였다. 식습관의 각 문항에 대한 점수를 구하기 위하여 응답 보기에서 가장 좋은 식습관에 대하여 0점, 가장 좋지 않은 식습관에 대하여 2점을 부여하고, 이 두가지 식습관 사이에 중간 정도의 보기가 있는 경우 1점을 부여하였다. 부여된 점수로 계산한 각 문항의 식습관 점수와 미량영양소 섭취부족 위험지표와의 Pearson 상관계수를 계산한 결과 유의적인 상관관계를 나타낸 식습관 문항은 세끼 식사 여부, 아침식사 시간의 여유, 저녁식사의 규칙성, 식욕, 그리고 김치, 우유, 과일, 콩의 섭취 빈도에 관한 8개 문항으로 나타나 이들을 평가표에 포함시킬 문항으로 선정하였다. 또한 이 8개 문항에 가중치를 부여하기 위해 MAR과 단계적 회귀분석을 실시하였고 그 결과 유의수준이 0.05 미만인 4개 문항의 배점을 1점으로 낮추었다. 식습관평가표의 영양부족위험 진단기준을 설정하기 위해 MAR < 0.75를 미량영양소 섭취부족군, MAR ≥ 0.75를 적정군으로 하여 총점 분포를 살펴본 후 각 총점의 민감도, 특이도, 양성예측도를 평가하였고 이 결과에 따라 식습관평가표의 총점이 3점 이하 일 때 저위험군, 4~5점일때 중간위험군, 6점 이상일 때 고위험군으로 결정하였다. 식습관평가표의 진단기준에 따라 본 조사대상자를 세 집단으로 분류하고 영양소섭취를 비교한 결과 에너지와 단백질은 세 집단간 대상자 분포의 유의적 차이가 없었으나, 11개의 미량영양소 중에서는 비타민 A, 티아민, 리보플라빈, 니아신, 엽산, 칼슘, 인, 철, 아연 등 9개 영양소에서 평균 필요량 미만으로 섭취한 대상자의 비율이 고위험군이 가장 높았으며, 중간위험군, 저위험군의 순으로 유의적인 차이를 나타냈다. 그러나 비타민 C의 경우 중간위험군과 고위험군 간에는 차이가 없었으며, 저위험군은 유의적으로 낮았고, 비타민 B?의 경우 세 군 간에 유의적인 차이가 없었다. 본 연구에서 개발된 8문항의 식습관평가표는 복잡한 식이섭취조사를 실시하지 않고도 초등학생의 미량영양소 섭취부족 위험을 간편하게 선별할 수 있을 것으로 생각되며, 초등학생이 쉽고 간편하게 사용할 수 있으므로 이들을 대상으로 영양판정이나 영양교육을 실시할 때 활용할 수 있을 것이다. 또한 다양한 지역의 학생을 대상으로 활용하여 타당성 검토를 거치면 영양사업과 영양교육의 도구로서 유용하게 활용될 수 있을 것으로 보인다. The purpose of the study was to develop an eating habit checklist for screening elementary school children at risk of inadequate micronutrient intake. Eating habits, food intake, and anthropometric data were collected from 142 children (80 boys and 62 girls) in the 4<SUP>th</SUP> to 6<SUP>th</SUP> grades of elementary schools. Percentage of Recommended Intakes (RI) and Mean Adequacy Ratio (MAR) of six micronutrients; vitamin A, riboflavin, vitamin C, calcium, iron, zinc, and the number of nutrients the children consumed below EAR among the six nutrients were used as indices to detect the risk of inadequate micronutrient intake. Pearson correlation coefficients were calculated between eating habit scores and inadequate micronutrient intake indices in order to select questions included in the checklist. Meal frequency, enough time for breakfast, regularity of dinner, appetite, eating frequencies of Kimchi, milk, fruits and beans showed significant correlations with indices of inadequate micronutrient intake. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 8-item checklist with test results from 0 to 12 points was developed, and those with equal or higher than 6 points were diagnosed as high-risk group of inadequate micronutrient intake, and those with 4 or 5 points were diagnosed as moderate-risk group. Among our subjects 14.1% was diagnosed as high-risk group, and 30.3% as moderate-risk group. The proportions of the subjects who consumed below EAR of all micronutrients but vitamin C were highest in the high-risk group, and there were significant differences in the proportions of the subjects with intake below EAR of all micronutrients except vitamin B6 among the three groups. This checklist will provide a useful screening tool to identify children at risk of inadequate micronutrient intake. (Korean J Nutr 2009; 42(1): 38 ~ 47)

This study was conducted to investigate satisfaction and improvement of nutritional status among the participants of Nutri-Plus program held at Health Center located in Sangdang-gu, Cheongju, Chungcheongbuk-do, Korea. Questionnaire survey was carried out targeting total 190 participants including 5 pregnant women, 51 lactating women, 55 infants, and 79 children. Anthropometric, biochemical and dietary intake data before and after participation were collected to investigate the effectiveness of the program. The subjects were satisfied with the program and supplementary foods as assessed with the satisfaction score. The overall score was higher than 4 point out of 5 point criteria. While the subjects were satisfied with supplementary foods such as rice(unpolished rice, barley), milk, and eggs, they were not with potatoes(sweet potato, noodles), black beans(red bean, cereal), and carrots(green pumpkin). When the nutritional status was compared before and after the program, vitamin A intake of pregnant women was significantly increased after the program(p<0.01). Significant increases of hemoglobin concentrations(p<0.001) was found in lactating women with values from 11.7g/dl to 12.6g/dl along with significant increases in the intakes of energy, vitamin A, protein, calcium, and riboflavin. Height, body weight, and BMI of infants were significantly increased after the program(p<0.001), but the infants and children who were below 10th percentile in height and weight were decreased(p<0.001) and their hemoglobin contents were increased significantly(p<0.001) after the program. Significant increases were also observed in the intakes of energy, protein, calcium, iron, vitamin A, riboflavin, and vitamin C(p<0.05). Our study showed that the participants of the Nutri-Plus program were satisfied with the program and supplementary foods and nutritional status was improved after participating the program.

The purpose of this study was to analyze the contents of food advertisements on TV during children’s prime time. Food advertisements were examined on four television stations from 5 pm to 7 pm for a week in 2007. During the period, 62 unique food advertisements were aired a total of 201 times. Of the total 201 advertisements, the confectionary group was the most frequently advertised (33.3%), followed by food service restaurants (19.4%) and non-alcoholic beverages (18.9%). When the advertisements were categorized according to the target consumer group, those targeting ‘general consumers and adults’ were 61.7% and those targeting ‘children’ were 22.9%. The advertisements targeting children mostly featured animation characters, celebrities and peers. The most often used technique (41.9%) of the advertisements targeting children was a promotional offer which directed children’s attention to free toys. Advertised foods from 53.2% of 201 advertisements were incompatible with dietary guidelines for children. These results indicate that food advertisements exposed during children’s prime time may have negative impacts on children’s healthy food choices. Therefore, efforts should be made to establish a better food advertising environment for children by monitoring and controlling food advertisements
