The purpose of this study was to examine nutritional quality among Korean adolescents before and after implementation of school lunch program (SLP). Subjects were recruited from the second year at a junior high school in Seoul, Korea, in two consecutive years; N1=337 and N2=300 for the year 2003 and 2004, respectively. Food intake data was collected using a 3‐day food records. Although total energy intake was not different between after and before SLP, the percentage of fat (29.7%) was higher after than before (27.7%) SLP(p<.000). Intakes of cholesterol and phosphorus were significantly lower (p<.000) and intakes of fiber, carotene and zinc were significantly higher(p<.001) after than before SLP. Nutrients density of fat (p<.000), carbohydrate(p<.000), fiber(p<.000), potassium(p<.001), and folate(<.05) were greater after than before SLP. Dietary Variety Score(DVS) of lunch was higher after SLP (20.5±4.9) than before SLP(10.0±3.6). These findings suggest that nutritional quality based on the nutrient intakes such as fat, fiber, and cholesterol, and DVS of lunch were significantly affected by the implementation of SLP for Korean adolescents.
