The effects of a nutritional education program featuring cooking activities on 20 preschool children 6 years of age at a kindergarten in the Daegu suburb area. After applying the nutritional education program for 6 weeks, scores of dietary habits, dietary attitude and problematic dietary behaviors increased significantly from 3.68 to 3.83, 3.52 to 3.9 and 3.59 to 3.89, respectively (p<0.001). Problematic dietary habits, such as not eating a variety of foods, overeating, and having an unbalanced diet, were positively affected while problematic dietary behaviors, such as eating too much sweet food and liking instant foods, also underwent favorable changes. Among dietary attitudes, washing bands and brushing teeth before and after meals were the least changed items (0.15 out of 1). To improve dietary habits and behavior of preschool children, nutrition education programs cooking activities must be applied systematically.

The purpose of this study was to evaluate the effect of nutrition education on dietary knowledge, dietary attitudes, and dietary behavior of elderly by analyzing changes before and after nutrition education. This study was conducted in Seoul from March 2022 to December 2022 for 50 elderly (6 male, 44 female) who participated in nutrition education for 8 weeks at three senior welfare centers (Seodaemun, Seongbuk, Jongno). A total of 35 responses were used in the final analysis. Statistical analysis was conducted using descriptive statistics, paired t-test, and Wilcoxon's signed rank test by age, hypertension, and dislipidemia to find effect of nutrition education on their nutritional knowledge, dietary attitudes, and dietary behavior. Results showed that nutrition education had a significant effect on the elderly. In particular, for those with chronic diseases such as hypertension and dislipidemia, the difference after education was significant, indicating significant changes in dietary habits. This study is expected to provide basic data for the development of a systematic nutrition education program for the elderly in the future.

This study examined changes in dietary life and dietary life satisfaction in one-person households during the COVID-19 pandemic. Using a sample of 916 one-person households from the Food Consumption Behavior Survey, we applied ANOVA and a system of equations model for our analysis which produced four main results. Firstly, during the COVID-19 pandemic, eating homemade and delivered meals increased, whereas eating restaurant, group, and HMR meals decreased. Eating breakfast and regular eating habits also increased during the pandemic. Secondly, approximately 30% of the sample reported increased expenditure on fresh food and HMR meals. The proportion of positive changes in dietary life was also greater than negative changes, and dietary life satisfaction was about three times higher than it had been before the pandemic. Thirdly, having breakfast and regular eating fully mediated the relationship between spending on fresh food and dietary life satisfaction, as well as the relationship between HMR purchases and dietary life satisfaction. Changes in expenditure on fresh food and HMR meals positively affected dietary life satisfaction through eating breakfast and regular eating. Fourthly, increased consumption of delivered food had a positive direct effect on dietary life satisfaction. Among sociodemographic variables, gender, education, occupation, and age were also significantly related to changes in dietary life satisfaction.

Retarding effects of the dietary fibers from persimmon peels (PTDF ; total dietary fibers, PIDF ; insoluble dietary fibers, PSDF ; soluble dietary fibers) and dried jujubes (JTDF ; total dietary fibers, JIDF ; insoluble dietary fibers, JSDF ; soluble dietary fibers) on glucose, bile acid and cadmium transport were evaluated by in vitro dialysis sack method. These effects were compared with those of commerical citrus pectin, CM-cellulose (CMC) and $\alpha$-cellulose. Yields of PTDF, PIDF and PSDF on wet weight basis were 14.04% , 11.61%, 1.76%, respectively, and those from dried jujubes were 14.80%, 9.98% and 2.80%, respectively. The amount of soluble fibers in JTDF was higher than PTDF. Soluble fibers had the retarding effects on glucose transport but insoluble fibers did not have. CM-cellulose showed the greatest retarding effect, which was followed by citrus pectin and JSDF. Among the soluble fibers, PSDF had the lowest retardig effect. Retarding effect of TDF was dependent upon the amount of SDF in TDF. Regarding bile acid dialysis , insoluble dietary fibers as well as soluble dietary fibers showed the retarding effects, among which JSDF had the greatest retarding effects, among which JSDF had the greatest retarding effect, followed by citrus pectin. Among the extracted fibers, dietary fibers from dried jujubes were more effective than these from persimmon peels, and SDF seemed to show higher retarding effects than IDF and TDF. On cadmium transport retardation , all dietary fibers except $\alpha$-cellulose had the retarding effects and PSDF showed the greatest effect which was followed by PIDF and CMC, The extracted fibers showed higher retarding effect on Cd transport than glucose and bile acid transport, and dietary fibers from persimmon peels showed higher retarding effects than those from dried jujubes.

This study was to obtain information about the dietary habits, the dietary attitudes, nutrition knowledge, and the food consumption of middle school students and to assess relationships between the dietary habits, the dietary attitudes, and nutrition knowledge of middle school students. Data were collected from 390 middle school students in Kimcheon. In the dietary habits, the regularity of breakfast showed the highest point and the snack consumption showed the lowest point. Female students were lower in the regularity of breakfast, and male students were higher in overeating of dinner and night. In the dietary attitudes and the perceived importance of nutrition, male students showed more favorable attitudes and perceived more importance of nutrition. In the nutrition knowledge, the responses to items 'Cola or cider doesn't have calories' and 'An egg contains lots of cholesterol' were the lowest point. Female students had higher knowledge than male students. In the food intake, grains, milk.yogurt.cheese, and fruits were always eaten or frequently eaten. While fast food, spicy and salty food, seaweeds, carbonated drinks, and yellow or green vegetables were eaten in lower frequency than other foods. Male students consumed more meat.ham.egg.fish, fried.stir-fried food, fast food, carbonated drinks, and spicy and salty food than female students. The correlation between dietary attitudes and dietary habits was statistically significant. The correlation between dietary attitudes and the perceived importance of nutrition was statistically significant. But the correlation between dietary attitudes and nutrition knowledge was statistically significant for female students, not significant for male students. Nutrition knowledge was related to the perceived importance of nutrition. It might be suggested that effective nutrition education program might be developed and implemented to ensure the good eating behaviors of middle school students.

BACKGROUND/OBJECTIVES: As the prevalence of chronic diseases has risen, the need for straightforward diagnostic tools for monitoring nutrition status to improve nutrition counseling and disease prevention has likewise increased. This study developed an easily usable dietary behavior pattern diagnosis checklist and investigated its correlation with dietary quality index. SUBJECTS/METHODS: A draft dietary pattern evaluation tool was generated by analyzing previous studies. The draft questionnaire comprised 61 questions for assessing dietary habits. A survey was administered to 320 adults (19 to 64 years old) using the dietary pattern evaluation tool and 24-hour-recall method between March and May of 2014 in Jeonbuk province and the metropolitan area. Principal component analysis with varimax rotation was performed to identify dietary behavior patterns. Nutritional analysis was conducted using CAN-Pro 4.0, and the Diet Quality Index-International (DQI-I) was calculated to assess dietary quality. The correlation between dietary pattern scores and DQI-I scores was also analyzed. RESULTS: The factor analysis resulted in a total of 34 questions mapped to four main dietary behavior patterns: "high fat and calorie" pattern (12 questions), "overeating/binge" pattern (nine questions), "dietary impulse" pattern (eight questions), and "unbalanced food intake" pattern (five questions). The four dietary behavior patterns were negatively correlated with DQI-I adequacy and total scores (P < 0.01). CONCLUSIONS: The dietary pattern evaluation tool developed in this study can be used to diagnose a client's dietary behavior problems and is available as a nutrition counseling tool in the field.

This study was conducted to investigate whether there were any differences in the body image perception, dietary behavior and maternal dietary guidance between an obese group (“OG”) and a normal weight group (“NWG”), and furthermore, to provide basic informations for comprehensive educational programs for obese children. For this purpose, the questionnaire method was used. The subjects were 1,501 elementary school children, in the 4th to the 6th grades in Seoul, Busan, Daegu, Gwangju, and Andong, and their mothers (1,459). The percentage of the children who misperceive their body image was higher among the girls (30.4%) than the boys (22.6%) The average scores for balanced dietary behavior as assessed by the children was higher in the OG than in NWG; the average scores for dietary control as assessed by their mothers was higher in the NWG than in the OG. The scores for dietary behavior as assessed by the children was different from those as assessed by their mothers. Assuming that the mothers would give more correct and balanced answers, the development of a reliable questionnaire for dietary behavior that could be more accurately answered by the children is necessary. Maternal dietary guidance for dietary control was more frequently given in the OG as compared with the NWG and more frequently in girls as compared with boys ; while that for balanced diet was more in the NWG as compared with the OG. The worse the mothers estimate of the dietary behavior for their children, the more they tried to guide their children in dietary behavior. It is recommended that the children should be taught to correctly recognize the degree of their obesity, and receive the appropriate educational program accordingly, including the maternal dietary guidance.

This study has dealt the effect of Ca regulating hormones and dietary Ca levels on Ca metabolism. Animals(BALB/c mice) were divided into three dietary groups(high and medium Ca and Ca free) and hormones including parathyroid hormone(PTH), calcitonin(CT), cholecalciferol(Vit D) were i.p. injected. After feeding experimental diets for five weeks, mice were anaethetized and sacrificed by heart puncture. We found that femur growth of mouse was slightly increased by high dietary Ca without showing statistical significance comparing to low dietary Ca group. The combination of PTH and CT showed the same effect when dietary Ca was high. At the same time, total mineral retention in bone was most affected by dietary Ca. In general, high Ca diet elevated Ca level in the serum. When dietary Ca was low, PTH stimulated Ca release from the bone into the serum, which was shown to be inhibited by CT treatment. Comparing to the control, PTH, Vit D and CT together tended to inhibit serum Ca level at high and medium dietary Ca. PTH and Vit D inhibited Ca reserve in the liver at all dietary levels of Ca. Both PTH and Vit D stimulated bone Ca retention when dietary Ca was low, but this effect was reversed when dietary Ca was high. When PTH, Vit D and CT were administered together, bone Ca level was greatly enhanced at low dietary Ca than at high dietary Ca, which suggests that these hormonal cooperation is needed for proper bone density maintenance especially when dietary minerals are not sufficient.

The Dietary Reference Intakes which were developed by the Food and Nutrition Board, National Academy of Sciences of the United States, and Health Canada provide a good deal of information on nutritional requirements which apply to Korea. In addition, the processes of evidence based review of information on nutrient needs, dietary excess, and the assessment and planning of dietary intakes may be useful in Korea as well as North America. However, other aspects of the Dietary Reference Intakes may not be appropriate. This article discusses these issues.
