This study examined the utilization of processed food and the recognition of food labels among 257 university students (201 females and 56 males) in Seoul and Kangwon-do. The results of the study showed that the most important considered information on food labels are shelf life, nutrition facts, and price in sequential order. Female students' recognition of nutrition facts was significantly higher than that of male students (p<0.05). Female students more attentively checked the manufacturer, origin of the products, and shelf life information on food labels than did the male students. In checking out the food labels information, the most checked items on food labels were calories, trans fatty acid and cholesterol in that order and the least checked information was the sodium contents. Among processed foods, male students' consumption was dominant in instant noodles, frozen dumplings, and canned goods, while female students had more candies/chocolates. In selecting processed foods, male students showed strong preference for cheaper and quantitative products, while female students chose more tasty, brand new, well-known brand, and products of domestic origin. Frequency of canned and frozen food consumption showed a positive correlation with BMI, while candies/chocolates showed a negative correlations with BMI. Negative correlations were found in the attitude of selecting food with longer shelf life and BMI. The results of this study suggest that university students need to be well informed to make wise food choices that contribute to a healthy diet. Additionally, food manufacturers and government authorities concerned should make certain that consumers know how to use food label information more easily and effectively through proper education.

The objective of the this study was to identify the potential relationship between eating breakfast together as a family and the nutritional status among Korean adolescents based on the 2013~2015 Korean National Health and Nutritional Examination Survey data. This study investigated 1,300 adolescents ranging in agee from twelve to eighteen years-old. In this study, according to their eating breakfast together as a family or skipping breakfast, we classified the subjects into the eating breakfast together as a family (EBF group) (male=379, female=295), eating breakfast alone (EBA group) (male=177, female=169) and skipping breakfast (SB group) (male=152, female=128). Both male and female, age in the EBF group was lower than those of the EBA and SB group (p<0.0001, respectively). In the male, the EBF group exhibited significantly higher fiber (p=0.0168) and potassium density (p=0.0065) and lower beverage intake (% energy) (p=0.0040) than the EBA and SB groups. No difference was observed the proportion of subjects who practiced a healthy diet between three groups, however, the EBF and EBA groups had a smaller proportion of subjects who were in a condition of hypo-nutrition compared to the SB group (p<0.0001, respectively). The present findings suggest that the practice of eating breakfast together as a family in adolescents may bean important consideration in relation to micro-nutrient intake status.

Purpose: To estimate the prevalence of dietary supplement (DS) use, investigate the related factors associated with DS use among preschoolers and support the adequate nutrition. Methods: We conducted a questionnaire survey of mothers of children aged between 1 and 6 years who visited pediatric clinics in 3 Korean cities (Jeonju, Suncheon, Jeongeup) between October and November 2012 at Presbyterian Medical Center. The responses from 929 questionnaires were analyzed. Results: Approximately 45.1% of the preschoolers used DS in the past month. The following factors were associated with greater use of DS: older age (p<0.001), whether or not the preschoolers attended kindergarten (p<0.001), higher mother's concern about the nutritional facts (p<0.001), whether or not the mother use DS (p<0.001), whether or not the mother counsel with a doctor or pharmacist about DS use (p<0.001). Vitamin mineral supplements (77.5%) were the most commonly used DS among the preschoolers, followed by ginseng (49.3%) and probiotics (25.6%). Additionally, of the DS users, 95.9% gave DS to their healthy children. Of the users and non-users, 97.6% and 62.2%, respectively, indicated that they would like to have their children take DS. The information on DS was obtained from family or friends in 48.2% of the DS users and from doctors in only 6.1%. Conclusion: Approximately half of the preschoolers in our study used DS, which might not have been medically indicated for most of them. Therefore, the role of professionals in counseling on desirable diet behaviors and DS use for preschoolers is warranted.

Objectives: The study investigated constipation in male and female high school students and in order to provide data base for development of education and intervention programs aimed at preventing and managing constipation in high school students. Methods: The study used a technique of convenience sampling to mobilize the entire students in an academic high school in D region. Of the combined 360 copies of questionnaire distributed, 340 copies were collected and used for the final analysis. The gathered data were analyzed using frequency, percentage, and ${\chi}^2-test$ in SPSS 21. Results: The ratio of female students with constipation is significantly higher than that of male students with the condition(${\chi}^2=5.73$, p=0.017), and there were significant differences in exercise habits(${\chi}^2=26.75$, p<0.001), eating habits(${\chi}^2=43.19$, p<0.001), and bowel habits(${\chi}^2=22.96$, p<0.001) between female students and male students. Also there was significant difference in water intake between the normal group and the constipation group(${\chi}^2=10.01$, p=0.040). Significant differences between the two groups were also discovered in the level of perception of constipation(${\chi}^2=98.76$, p<0.001), bowel movement time(${\chi}^2=15.74$, p=0.008), and use of laxatives(${\chi}^2=17.68$, p<0.001) and enema(${\chi}^2=16.97$, p<0.001) for constipation relief. Conclusions: To prevent and manage constipation in high school students, education about healthy dietary, and bowel habits is required. Also there is an urgent need to improve the school toilet environment in order to respect the rights of students to void or defecate when necessary, a process which will require involvement of students, teachers, and other school staff.

The present study was conducted to examine the effect of an increased level of dietary sodium on calcium excretion in 8 health young adult Korean women on a controlled diet. After adaptation period of 2 days, each subject received 2811.8$\pm$68.1 mgNa(day during the initial period of 5 days (low sodium period) and 6417.1$\pm$248.6mgNa(day during the following period of 5 days (high sodium period). Calcium intake was 593.7$\pm$15.7 mg Ca/day during the low sodium period of 596.1$\pm$25.1 Ca/day duing the high sodium period. When the low sodium period is compared with the high soidum period, the results were as following. 1) Mean urinary sodium excretion was significantly higher during the high sodium period (5760.1$\pm$156.5mg0 than during the low sodium period (2272.2$\pm$108.6mg)(P<0.001). Fecal sodium excretion of the high sodium period was also significantly higher than that of the low sodium period(P<0.001). Mean value of sodium balance during the high sodium period was higher than that of the low sodium period . However, the difference was not significant. 2) Mean urinary calcium excretion was significantly higher during the high sodium period than during the low sodium period ; mean value of the low sodium period was 124.7$\pm$11.3mg and that of the high sodium period was 202.6$\pm$17.2mg)P<0.001). Fecal calcium excretion was higher during the high sodium period (284.9$\pm$31.0mg) than during the low sodium period (253.9$\pm$15.3mg0, but there was no significance. Mean value of calcium balance during the high sodium period was significantly lower than that of the low sodium period(P<0.001). The above results show that high sodium intake increases calcium excretion as well as sodium excretion.

This study was conducted to investigate the nutritional knowledge, nutrients intake and the assessment of dietary behavior of old peoples living in Incheon area. Two hundred and three elderly were examined using the questionnaire. The results of this study are summarized as follows. 1. The old people was lacking in correct information about nutrition and diseases. 2. The nutritional knowledge scores of old women were higher than those of old men and the scores went up according to the amount of pocket money. 3. The amount of vitamin C and phosphorus intakes were higher than those of the RDA, protein intake reached the level of the RDA. The vitamin B$_2$intake, however, was below 75% of the RDA and that of calcium was very low in women, especially. 4. Most of subjects had a meal regularly three times a day and the skipping rate of breakfast was very low. Dey had a moderate meal volume and did not have an unbalanced diet. Dey nearly do not take the processed food, dine out and exceed in the cholesterol intake. 5. They took green and yellow vegetables and, milk and milk products relatively small. On the other hand, the intake of caffein beverage was relatively high. the rates of drinking and smoking were low. From these results, we may propose the conclusion as follows: The old people were much concerned about the nutrition and diseases, but they had no correct informations about them. Therefore, the program of nutrition and dietary behavior for their healthy elderly life had to be prepared and to be applied to them immediately.

This study was conducted to explore the relationship between locus of control and health belief. the life style of gastric cancer patients. The subjects of this study were 40 of the early gastric cancer and 90 of the advanced gastric cancer who first visiting patient to general surgery out patient department of Chungnam University Hospital for operation. The data was collected with structured questionnaire from July. 1998 to Feb. 1999 The tool were Moon's Health Belief Scale and Multiple Locus of Control of Wallston. Wallston, DeVellis. The data was analysed by SAS program using frequency, $X^2$-test, Pearson's correlation coefficient, ANOVA. Scheffe-test, t-test. The results were as follows 1. 30.8% of subjects were early gastric cancer anf 69.2% were advanced gastric cancer. The subject knowing about diagnosis was 83.1%. 16.9% did'nt know about diagnosis. 2. The correlationship between Health belief and Locus of control of subjects was not supported. 3. There was statistically no difference of life style between early and advanced gastric cancer patients. 4. There were statistically significant differences in perceived sensitivity according to weight. educational level. and birth order, in perceived barrier according to educational level. and in perceived severity according to occupation among demographic characteristics of study subjects. From above results. health professional has to educate general population to detect gastric cancer early to improve survival rate because early gastric cancer is high in survival rate, and to prevent recurrence and to maintain continuing healthy status. In the future, gastroscopy also has to expand to detect early. For there was no difference in life style between early and advanced gastric cancer. carcinogen related to diet should be emphasized through education. The perceived benefit among health belief model was not supported in this study therefore further study and comparison between gastric cancer and normal population are needed.

This study was designed to investigate the effectiveness of ginseng intakes in modifying serum lipid profiles and plasma clotting factors. The participants in this study were 47 normal healthy volunteers(men 24, women 23) with an age range of 35-49 years and a mean age of 41 years residing in Taejon. Based on the diet intakes, subjects were classed into one of three groups : control, vegetarian, and ginseng consumed over 3-4 years. There was no significant difference in their physical characteristics. Dietary calorie intakes were not significantly different in subjects. The ratio of energy intake in the control and ginseng consumed group was 63-64% : 20-21% : 15-16%(Cho : Fat : Pro), but 70-73% : 13-14% :14-15%(Cho : Fat : Pro) in the vegetarians. The intakes of animal food in the vegetarian was significantly lower than the control and ginseng consumed group in men. The ratio of P/S(1.27) was the highest in the vegetarians. Venous blood samples were taken for serum lipid profiling, plasma clotting assay and platelet function. The concentration of serum triglyceride in the men ginseng group is significantly lower than those of the men control group. Serum lipid profiles values of the men ginseng group, such as total cholesterol and phospholipid were lower those of the men control group, but higher those of the men vegetarian group. the serum lipid profile in the women were not significant, but total cholesterol, triglyceride and LDL cholesterol levels in the ginseng groups were low. The concentration of HDL cholesterol was not significantly different. Platelet cell count and platelet aggregation were low in the ginseng groups. APTT(Activated Partial thromboplastin time) was significantly elongated in ginseng groups in the normal range. In seems that the major beneficial effects of ginseng intakes in especially men were on the blood concentrations of triglyceride, total cholesterol and elongation of plasma clotting time.

To provide approprate nutrition informatios and guidelines for the healthy school lunch program(SLP) menus, the nutritional quality of the SLP and the nutrients that affect the food cost of SLP were evaluated after analysis of recipes and food price lists of 776 menus collected from 10 elementary SLP schools in Seoul and Kyunggi province in Korea in the year of 1995. Index of nutritional quality of SLP menus were good enough, showing over 1.0 in all nutrients except vitamin A(0.86) in kyunggi province. The percent of calories from carbohydrates, protein and fat was 52%, 16% and 32%, while the polyunsaturated fatty acid/monousaturate fatty acid/saturated fatty acid(P/M/S) ratio was 1.0/0.95/1.15. On the other hand, the nutrient-cost evaluation showed that the most expersive nutrient for the RDA(Recommended Dietary Allowance) standard of SLP was origined from the cost of energy and vitamin A. In Pertary correlation analyses, the cost of SLP meals was positively asociated with energy(r=0.244, p<0.001), protein(r=0.306, p<0.001) and carbohydrate(r=0.159, p<0.001) in diet, while the most important predictor of the cost of SLP meal provides sufficient nutrients with enough calories, but fat level is somewhat higher than the suggested value from Dietary Guidelines for Koreans. These data also suggest that meals which could offer enough vitamin A might be included in SLP menus and the cost of a SLP meal can be reduced when choosing the cheap protein source food.

It has been suggested that green juice supplementation may have some health promoting benefits. We evaluated the effects of green juice (Angelica keiskei) consumption on parameters of lipid profiles and plasma antioxidant status in healthy male smokers. Fifty-four smokers were supplemented with 300 ml of green juice for 6 weeks while maintaining their normal diet. Blood samples were collected on week 0 and week 6 in order to evaluate plasma lipid profiles (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol) , plasma antioxidant vitamin levels (ascorbic acid, $\alpha$ -tocopherol, ${\gamma}$ -tocopherol, $\alpha$ -carotene, $\beta$ -carotene, cryptoxanthin and lycopene) , the degree of LDL oxidation and GOT, GPT levels for liver function. Plasma ascorbic acid level remained at the same level. However, $\alpha$ -tocopherol and ${\gamma}$ -tocopherol normalized by total cholesterol (p <0.05) and $\beta$ -carotene (p <0.001) level were all significantly increased after green juice supplementation. Plasma cholesterol was reduced for 12%, LDL-cholesterol was reduced for 9.3% after green juice consumption, while plasma triglyceride and HDL-cholesterol was not changed. Oxidized LDL assessed by conjugated diene (CD) , was decreased (p < 0.0001) after green juice consumption. These results further support a role for green juice supplementation in the improvement of lipid status, prevention of lipid peroxidation, and thereby reducing risk factors of numerous diseases associated with elevated oxidative stress in smokers.
