Abstract

The purpose of this study was to evaluate nutrition intake and diet quality according to beverage consumption status in elementary school students (ESS = 317), middle-school students (MSS = 431), and high-school students (HSS = 373). We analyzed data from the combined 2007-2008 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into two groups, the non-beverage group and the beverage intake group according to beverage intake from drink types (fruit-vegetable drinks, carbonated drinks, and dairy drinks). Intake of dairy drinks was significantly lower in the carbonated drinks intake (CDI) group, compared with the non-CDI group in the MSS group. Intake of vitamin C was significantly higher in the fruit-vegetable drinks intake (FVDI) group, compared with the non-FVDI group. Intake of Ca and P was significantly lower in the CDI group, compared with the non-CDI group. Intake of vitamin B2, Ca, and P was significantly higher in the dairy drinks intake (DDI) group, compared with the non-DDI group. The mean adequacy ratio (MAR) of the FVDI group and the DDI group was significantly higher than those of the non-FVDI and non-DDI group. In diet quality, nutrients less than 1 on the index of nutritional quality (INQ) were significantly higher in the CDI group, compared with the non-CDI group. In conclusion, consumption of carbonated drinks dropped the diet quality however, consumption of fruit-vegetable drinks and dairy drinks improved the diet quality of micronutrients. Therefore, a well-planned diet must be used for replacement of nutrients lost from excessive intake of carbonated beverages during a time in life when growth is especially prominent.
