Abstract

The purpose of this study was to analyze the content and consumption of total sugar from school lunches at Incheon and Chuncheon. The samples were collected from eight elementary schools and eight middle schools in Incheon and Chuncheon for 15 days. The analysis of total sugar content was performed for 1334 main dishes, side dishes, and desserts, which were supplied by elementary and middle school foodservices. Total sugar content was extracted from various types of food with 50% ethanol after defatting. We simultaneously analyzed sugars such as fructose, glucose, sucrose, maltose, and lactose by a high performance liquid chromatography with refractive index detector. The average lunch intake for elementary school and middle school students was $372.6{\pm}72.2g$ and $449.2{\pm}81.1g$, respectively. The total sugar content in desserts was $7.21{\pm}6.32g/100g$, $1.69{\pm}2.44g/100g$ in side dishes, and $0.32{\pm}0.77g/100g$ in main dishes. Among side dishes, fried foods, stir-fried foods, and sauces contained the highest amounts of total sugar. The total sugar intake was $4.63{\pm}5.11g$ in desserts, $0.64{\pm}1.01g$ in side dishes, and $0.55{\pm}1.48g$ in main dishes. Main and side dishes with a high total sugar intake included cooked rice with seasoning, fried foods, stir-fried foods, and preserved foods. The average total sugar intake per meal for elementary school, middle school, and all students was $4.03{\pm}3.67g$, $6.97{\pm}6.59g$, and $5.50{\pm}5.53g$, respectively. We have provided useful information to decrease the intake of total sugar in school lunches. It is recommended that total sugar intake be continuously monitored.

본 연구에서는 인천과 춘천지역에서 각각 초등학교 4개 학교와 중학교 4개 학교 등 총 16개 학교를 선정하여 주식, 부식 및 후식 등 1334건의 메뉴에서 당 함량 및 당 섭취실태를 조사하였다. 학교급식을 통한 섭취량은 전체 평균 $410.9{\pm}85.8g$/인이었다. 전체 급식메뉴의 평균 당 함량은 $1.93{\pm}3.35g/100g$이었으며, 급식메뉴를 주식, 부식 및 후식으로 나누었을 때 평균 당 함량은 후식류($7.21{\pm}6.32g/100g$)>부식류($1.69{\pm}2.44g/100g$)>주식류($0.32{\pm}0.77g/100g$) 순으로 나타났다. 평균 당 함량은 주식류에서 면류>죽류>일품식밥류 순으로 높았고, 부식류에서는 소스류>튀김류>절임류>무침 나물류>볶음류 등의 순으로 높게 나타났다. 당 섭취량 또한 후식류($4.63{\pm}5.11g$)>부식류($0.64{\pm}1.01g$)>주식류($0.55{\pm}1.48g$) 순으로 높게 나타났다. 급식 중 당 섭취량은 주식류에서는 일품식밥류의 당 섭취량이 높았고, 부식류에서는 튀김류>볶음류>소스류>조림류의 순으로 당 섭취량이 높았다. 후식류에서는 음료와 유제품류의 당 함량과 섭취량이 다른 음식군에 비해 높았다. 급식일별로 점심 급식 한 끼에 섭취하는 평균 당 섭취량은 초등학생 $4.03{\pm}3.67g$/인, 중학생 $6.97{\pm}6.59g$/인이었으며, 전체 평균 당섭취량은 $5.50{\pm}5.53g$/인으로 한국인 총당류 섭취기준치와 비교했을 때 높지 않은 수준으로 나타났다. 그러나 Kang과 Yoon(8)의 연구결과 초등학생의 91.5% 가 주로 하루에 1-2회 간식을 섭취하며, 선호하는 간식이 과자, 과일 또는 과일주스, 빵 또는 케이크류 순으로 나타나 학생들의 간식을 통한 당 섭취는 높을 것으로 사료된다. 따라서 학교급식을 통해 단 맛에 길들여지지 않으며 올바른 식습관을 형성하도록 영양교육할 필요가 있다. 또한 학교별로 조리사와 조리법에 따른 당 함량에 차이를 보임에 따라 당 함량을 줄일 수 있는 조리법의 개발, 통일된 조리법의 보급 및 조리사의 교육과 급식 식단 구성 시 당 섭취량이 높았던 음식군을 중복하지 않고, 후식류로 과일류를 제공하는 등 메뉴의 조합에 주의함으로써 학생들의 당 섭취량을 줄일 수 있을 것으로 사료된다.
