- OBJECTIVES
The purpose of this study was to examine the coverage of the current mandatory nutrition labeling system on the nutrient intake of Koreans.
METHODS
KNHANES dietary intake data (2013) of 7,242 subjects were used in the analysis. KNHANES dietary intake data were collected by a 24-hour recall method by trained dietitians. For analysis, all food items consumed by the subjects were classified into two groups (foods with mandatory labeling and other foods). In the next step, all food items were reclassified into four groups according to the food type and nutrition labeling regulations: raw material food, processed food of raw material characteristics, processed foods without mandatory labeling, and processed foods with mandatory labeling. The intake of energy and five nutrients (carbohydrate, protein, fat, saturated fat, and sodium) of subjects from each food group were analyzed to determine the coverage of the mandatory nutrition labeling system among the total nutrient intake of Koreans.
RESULTS
The average intake of foods with mandatory labeling were 384g/day, which was approximately one quarter of the total daily food intake (1,544 g/day). The proportion of energy and five nutrients intake from foods with mandatory labeling was 18.1%~47.4%. The average food intake from the 4 food groups were 745 g/day (48.3%) for the raw food materials, 54 g/day (3.5%) for the processed food of raw material characteristics, 391 g/day (25.3%) for the processed foods without mandatory labeling, and 354 g/day (22.9%) for the processed foods with mandatory labeling.
CONCLUSIONS
Although nutrition labeling is a useful tool for providing nutritional information to consumers, the coverage of current mandatory nutrition labeling system on daily nutrient intake of the Korean population is not high. To encourage informed choices and improve healthy eating habits of the Korean population, the nutrition labeling system should be expanded to include more food items and foodservice menus.

- The purpose of this study was to investigate the relationships of stress, depression, binge eating and food behavior of high school girls with their degree of BMI. One hundred twenty high school girls from the Seoul metropolitan area participated in this study. Self-administrated questionnaires to search for degree of stress, depression, binge eating, and food behavior were distributed. Anthropometric assessment was carried out to calculate the body mass index (BMI). The results are as follows: The mean of age and BMI of the subjects were 17.6 +/- 0.6 years and 21.0 +/- 2.9 kg/m2 (ranged from 15.4 to 31.7 kg/m2), respectively. 16.7%, 65.8% and 17.5% of the subjects were classified as under weight, normal weight and overweight, respectively. The average scores of stress, depression and binge eating were 124.9 +/- 31.4, 15.2 +/- 9.8, 29.5 +/- 7.8 points, respectively. The food behavior score was 11.5 +/- 2.4 points. Their degree of stress, depression, binge eating was significantly higher in overweight high school girls compared to underweight or normal weight high school girls. There were significant correlations of BMI with stress (P < 0.05), depression (P < 0.001), and binge eating (P < 0.01). Also there were significant correlations of food behavior with stress (P < 0.05), depression (P < 0.05) and binge eating (P < 0.001). These results indicate that the high school girls who have higher BMI seem to have more stress, depression, and binge eating habits. Also the high school girls who have more stress, depression and binge eating habits have poor food behaviors. Therefore proper control of emotions is required to maintain desirable food behaviors in high school girls.
