Abstract

Korean government will set up the nationwide food safety system with strict control of hazardous nutrients like sugar, fatty acids and sodium as well as advanced nutrition education system. In addition, almost one hundred percent of school food service rate forced the government to consider more effective ways to upgrade the nutritional status of school meals. The object of our study was to provide the data on content and consumption of sugar in school meal for the nationwide project. For this purpose, we surveyed the sugar content of 842 school meal menus and their intake level for 154 days in 8 schools in Daejeon and Chungcheong Province. Sugar contents, the sum of the quantity of 5 sugars commonly detected in food, were analysed with HPLC-RID (Refractive Index Detector). Sugar intakes were calculated by multiplying the intake of each menu to the sugar content of that menu. The sugar content was highest in the desserts, which include fruit juices, dairy products and fruits. Sugar content of side dish was high in sauces and braised foods. Sugar intake from one dish is high in beverage and dairy product, and one dish meals contribute greatly to sugar intake because of their large amount of meal intake. The average lunch meal intakes of second grade and fifth grade elementary school students were 244 g/meal and 304 g/meal, respectively. The meal intake of middle school student was 401 g/meal. The average sugar intake from one day school lunch was 4.22 g (4.03 g on elementary and 5.31 g on middle school student), which is less than 10% of daily sugar reference value for Koreans. The result of this study provides exact data of sugar intake pattern based on the content of sugar which is matched directly to the meals consumed by the students.

본 연구에서는 대전과 충남북 지역에서 지역별로 8개의 학교를 선정하고 각 학교당 4주간의 급식을 수거하여 842개 메뉴의 당 함량을 분석하였고, 수거된 급식메뉴에 대해 초등학교 2학년과 5학년, 중학교 2학년 남녀학생의 급식섭취량을 직접 측정하여 급식을 통한 2,806건의 당 섭취량을 산출함으로써 해당학교 및 지역의 당 섭취 특성을 대표할 수 있는 자료를 확보하였다. Fructose, glucose, sucrose, maltose, lactose의 함량 합으로 구한 총 당류의 함량은 가공식품에서와 달리 학교별로 임의의 조리법에 의해 조리된 음식이므로 그 범위가 넓게 나타났다. 주식류의 당 함량은 급식 100 g당 평균 0.20 g, 부식류는 2.08 g, 후식류는 5.13 g으로 과일음료와 유제품, 과일 등을 포함한 후식류의 당 함량이 다른 군에 비해 훨씬 높은 것으로 나타났으며, 부식류 중에서는 소스류와 조림류의 당 함량이 높았다. 급식메뉴 중 가장 많은 양을 섭취하는 음식은 일품식류, 음료 및 차류, 탕 및 전골류, 찌개류 순이었으며, 주스나 식혜와 같은 음료는 정해진 규격이 있어 다른 부식류에 비해 섭취량이 높게 나타났다. 부식류중에서는 국 종류를 제외하면 30~50 g 범위에서 찜류, 튀김류, 볶음류, 부침류, 조림류, 구이류 순으로 많이 섭취하였으나 무침.나물류와 김치류는 각각 13 g, 10 g만을 섭취하였다. 급식메뉴 중 후식류, 특히 음료 및 차류, 유제품류섭취로 인한 당 섭취량이 가장 많았으며 이들 식품은 당 함량도 높고 규격화된 중량으로 인해 섭취량도 많았기 때문이다. 일품식류는 낮은 당 함량에 비해 급식섭취량이 많아 후식류 다음으로 당 섭취에 크게 기여하였으며, 부식류에서도 조림류에 비해 당 함량이 낮은 튀김류의 급식섭취량이 많으므로 튀김류로 인한 당 섭취량이 조림류로 인한 것보다 높게 나타났다. 급식 한 끼니를 통한 당 섭취량은 평균 4.22 g으로, 학년이 높을수록 급식섭취량과 함께 끼니당 당의 섭취량도 많아 중학생이 5.31 g, 초등학생이 4.03 g을 섭취하였으며, 성별이나 수거시기에 의한 차이는 크지 않았다. 학교급식을 통한 한 끼니의 당 섭취량은 열량섭취량을 기준으로 정한 한국인 총 당류 섭취기준이나 한국인영양조사 결과의 하루 총 당류 섭취량의 10분의 1 이하 수준으로, 한 끼니 해당량으로서도 높지 않은 것으로 판단된다. 다만 과일주스, 식혜 등의 음료나 요구르트 등의 당 함량이 높은 식품이 제공되거나 이러한 후식류가 일품식류와 함께 제공되어 한 끼니당 당의 섭취량이 높은 급식일이 없도록 하는 데에는 관심을 가질 필요가 있을 것으로 판단된다.
