This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively.

Purpose: Although, the rate of skipping breakfast among adolescents has increased in recent years, there has been an increase in the consumption of home meal replacement (HMR). This study examines the recognition and preference of rice-based Korean style HMR for breakfast among adolescents in located at Jeollabuk-do. Methods: Total of 550 middle- and high-school students of Jeollabuk-do enrolled in this study signing a consent of participation. After conducting a preliminary survey, the questionnaire employed was modified according to the purpose of this study, and the self-recording method was appliedto fill out the questionnaire. Data were analyzed using IBM SPSS Statistics 25. The 𝛘²-test was performed for categorical variables, whereas continuous variables were analyzed by the independent t-test. Results: Results of this study determined that 272 students (54.6%) belonged tobreakfasteating group and 226 (45.4%) were in the breakfast-skipping group. The reasons specified by both groups for eating HMR were 'convenient to cook', 'delicious', and 'time-saving'. The a result of analyzing perception of the importance of HMR by classifying as whether to eat or not to eat breakfast, revealed that compared to the breakfast-skipping group, the breakfast-eating group considered 'hygiene and cleanliness' as important factors (p < 0.001). Considering the gender, school, and breakfast consumption, the most preferred Korean HMR were 'triangular gimbap', 'gimbap', and 'rice balls'. Conclusion: Results of this study indicate, when considering adolescents, there is a necessary for continuous researches to develop convenient breakfast substitutes that are easily consumed. Moreover, we believe that it is essential to impart proper cooking education and recipe distribution of the menu.

This study investigated the effect of salt preference on dietary habits and the body composition of university students. The subjects were divided into two groups: 85 students who dislike salt (salt-dislike (SD) group) and 104 students who like salt (salt-like (SL) group). We found that the SL group showed a higher preference for sweet, sour, spicy, and bitter flavors compared to the SD group. There was no significant difference in the frequency of eating breakfast according to the salt taste preference. The meal speed of the SL group was significantly higher than the SD group (p<0.01) and the body mass index of the SL group ($22.59kg/m^2$) was higher than SD group ($21.04kg/m^2$). The fat mass of the SL group (15.30 kg) was higher than the SD group (12.80 kg) (p<0.01). Salt preference and snack intake frequency had a significant and positive correlation with fat mass. The frequency of eating breakfast, and meal speed also showed a significant and positive correlation with subcutaneous fat. In conclusion, the SL group eats relatively more, speedily and frequently intakes snacks and carbonated drinks, likely resulting in higher body and subcutaneous fat. These results suggest salt preference is related to food choice, influences unreasonable eating habits, and possibly changes body composition. Taste preferences should therefore be considered for dietary consulting and nutritional education.

This study was conducted to determine factors affecting detection threshold and the optimally-preferred concentration for sweet taste, since investigation into factors decreasing sensitivity or increasing preference for sweet taste is important to prevent overconsumption of simple sugar. Subjects were 70 first-grade middle school students in the Gyeonggi-Do. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly were determined by sensory evaluation. A self-administered questionnaire was used to obtain the information regarding health-related lifestyle practices, dietary habits, preference for and eating frequency of Westernized foods and frequencies of eating foods other than home-made. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly of the subjects were 0.204% and 14.44%, respectively. Subjects who exercise less (< 30 minutes/week except PE class), skipping meals (${\geq}$ 3/week), type of breakfast rather than traditional Korean meal and frequent eating out and buying foods from school tuck-shop tended to have higher sweet taste threshold. There was significant positive correlation between the sucrose threshold concentration and fried chicken preference or eating frequency of hamburger. Those who exercise less (< 30 minutes/week except PE class) did have significantly higher optimally-preferred sweetness of omija jelly, which tended to be higher in the subjects who had more (${\geq}$ 4 out of 10) behavioral or psychological stress symptoms and who had early getting-up time (before 7 am). There was significant positive correlations between the optimally-preferred sweetness of omija jelly and pizza preference, instant noodle eating frequency or sum of eating frequencies of five fast foods. From the results of this study, it was suggested that middle school students should make efforts to stop skipping meals, exercise more, eat Korean traditional breakfast and reduce the frequencies of eating out and using instant/fast foods in order to prevent overconsumption simple sugar.
