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 done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (<36%) accounted for about 20% of the subjects. The mean levels of total cholesterol, HDL-cholesterol and TG were 188.4mg/dl, 69.9mg/dl and 67.4mg/dl, respectively. The percentages of the subjects with plasma total cholesterol level (> 200mg/dl) and LDL-cholesterol (＞130mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However. there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

I. Subject of the Study A study on the nutritive composition and utilization of wheat or barley for the improvement in our national dietary life. II. Purpose and Importance of the Stu요 1. Korea has long depended on rice for its staple food, but a sharp increase in population in recent years has brought about the shortage of rice, which makes it inevitable to import a great quantity of foreign rice. It is considered therefore that the development and utilization of other cereals than rice is a serious and pressing problem facing Korea. 2. Wheat and barley are the second largest products next to rice in Korea and it is desired that the composition of several kinds of wheat and barley be analysed and their nutrition which rates with differing degrees of hulling process be specified. 3. In this study, the experiment has been carried out in the following order: first, seven species were selected among various kinds of wheat and barley produced in Korea to analyze their respective composition, and to determine the most ideal degree of hulling process on 5 kinds among the 7 kinds: second, ratio of mixing rice with wheat or barley is increase the nutrition value and to seek selfsufficiency in staple food supply: third, economical and reasonable way of improving the nutrition value in the national dietary life is suggested by developing a simple and easy recipe which is also to the taste of the population. III. Contents and Scope of the Study 1. Objectives of the study The objectives will come under five items.

A $3{\times}2$ factorial experiment was conducted to determine the effects of dietary protein and lipid levels on the growth and body composition of juvenile far eastern catfish. Six diets were formulated to contain three levels of protein (20%, 30% and 40%) and two levels of lipid (9% and 17%). Triplicate groups of fish (initial body weight of 7.6 g) were hand-fed to apparent satiation for 66 days. Final mean weight was improved with increasing dietary protein and lipid levels, and the highest final mean weight was observed in fish fed the 40/17 (% protein/% lipid) diet. No significant difference was observed in final mean weight for fish fed between 30/17 diet and 40/9 diet. Feed efficiency of fish fed the diets containing over 30% protein levels with 9% and 17% lipid levels were significantly higher than those of fish fed the 20% protein levels. Feed efficiency of fish fed the 30/17 diet was not significantly different from that of fish fed the 40/9 diet or 40/17 diet. Feed efficiency and protein efficiency ratio of fish fed the 20% protein diets with 17% lipid level were significantly higher than those of fish fed 9% lipid diet. Daily feed intake of fish tended to decrease with increasing dietary protein and lipid levels. Moisture content of whole body in fish fed the 9% lipid diets was significantly higher than that of fish fed the 17% lipid diets at the same protein level, but the opposite trends were found for crude lipid content. Significant effects of dietary lipid were observed for most fatty acids, according to their relative values in the diets. The results of this study suggest that the protein requirement for maximum growth of juvenile far eastern catfish may be higher than 40%, and an increase of dietary lipid level from 9% to 17% can improve growth and feed utilization.

This study was conducted to compare the composition table of Korean food with that of foreign food. Analysis was made for Korean food composition table($5^{th}$ revision), Korean food composition table in Appendix of Recommended Dietary Allowances for Korean(6$^{th}$ th/ edition), Standard tables of food composition in Japan($5^{th}$ revised edition) and USDA Composition of Foods - Raw, Processed, Prepared. The method of content analysis was applied for this study and such differences were pointed out as the classification of food items, food items enlisted, the content unit of food and food components presented etc. To improve Korean food composition table, new food items and components should be added and old food items be eliminated based on the change of people's food consumption pattern. Also analysis for the domestic foods consumed by local people should be accomplished rather than borrowing foreign country's data.

This study was conducted to find out the weak points of present Korean food composition table, so that to suggest the revision direction. Korean food composition table in Appendix of Recommended Dietary Allowances for Korean, 5th edition, was analyzed by comparing with 6 other food composition tables such as one other Korean food composition table, and those of Japan(two), U.S.A., East Asia and Near East. The content analysis was applied as the method of this study. As result, many drawbacks like classification of food components, etc. were pointed out. The best solution to improve these drawbacks in present food composition table is establishing on organization entirely in charge of food composition table. In this way the organization can carry out food analysis systematically and continuously. Then new food items can be added, old food items be eliminated based upon people's food consumption pattern change. Also we need to analyze our own foods consumed by our people instead of borrowing the other country's data.

In Korea, there is an urgent need to identify nutrition-related risk factors for obesity, because the prevalence of these conditions continues to rise among Koreans. While some studies suggest that westernized dietary pattern may increase the risk of obesity, others do not support these findings. Longitudinal studies examined the role of dietary patterns in relation to changes in body fat composition. Nowadays rapid changes in dietary patterns are related to socioeconomic status and westernized diet. Major dietary changes include a large increase in the consuming of at in the diet and a fall in total cereal intakes and fiber. This research showed remarkable decline in the consuming proportion of the grains and vegetables. These results fit closely with the trend toward increased prevalence of obesity in Korea. Most longitudinal studies on these relationships among children and adults showed that the dietary patterns affected obesity. In conclusion, we need programs to promote healthy Korean diet pattern in Korea.

The effects of age and dietary fatty acid composition on prostagladin production was investigated in Sprague-Dawley strain male rats. Animals weighing 88.6$\pm$2.2g were fed 10% dietary fat(W/W, 20% of total energy). The P/S ratios of dietary lipid were three levels(0.5, 1, 2) and there were three different levels of n-6/n-3 fatty acid ratio(2, 4, 8) in each P/S ratio. The experimental period were 1 month and 12 months, respectively. The results of this study were as follows. As the age of rats increased, the plasma thromboxane B2 production increased, but aorta 6-keto prostaglandin F1$\alpha$ decreased. When a higher amount of n-3 fatty acid was fed in each P/S ratio, the relative percentage of linolenic acid and EPA in platelet increased.

The purposes of this study were to 1) examine the dietary patterns of fatty acids and the fatty acid composition in serum, 2) determine selenium (Se) concentrations, and 3) investigate how serum fatty acid compositon affects serum levels of Se in Korean elementary school children. The subjects consisted of 168 school children(82 boys & 86 girls) belonging to 1st through 6th grades, and their dietary assessment was evaluated. The serum fatty acid composition was analyzed by GLC, and the ICP/MS method was employed to measure serum Se concentration. Total average intake of PUFA, MUFA and SFA were 10.5g, 12.7g, 11.2g respectively. Total average dietary P/M/S ratio was 1.10/1.18/1.0. The average intake of $\omega$3 fatty acids and $\omega$6 fatty acids were 1.33g, 9.19g, respectively. The $\omega$6/$\omega$3ratio was 14.2 which is higher than the recommended range. In serum fatty acid composition, PUFA, MUFA, SFA were 40.6%, 28.1% and 31.6% respectively. The average $\omega$3 fatty acid composition was 3.80%, and the mean value of $\omega$6 series was 36.8%. The M/S ratio of girls was significantly higher than boy's in fatty acids intake and in serum composition. Mean Se concentration of total subjects was 416.7ug/l and it was significantly higher in the lower grades(1st-3rd)than in the upper grades(4th~6th, p<0.05). Although the mean serum Se concentration was negatively correlated with PUFA composition in total boys and girls, it was not significant. Serum Se concentration was negatively correlated with P/S ratio and C24:1 concentration(p<0.05). In addition, serum composition of $\omega$6 PUFA and C24:1 showed negative correlations with serum Se in only lower grades girl(1st~3rd), and further studies are needed to clarify in these phenomena. In conclusion, the mean serum Se concentration was significantly lower in upper grades (4th~6th)than in lower grades(1st~3rd) of elementary school children and was negatively correlated with P/S ratio of serum fatty acids. More detailed studies on relationship between Se and fatty acids are required.

This study was conducted to investigate the effect of dietary fiber(DF) levels on the meat quality in colored broiler. Colored broiler were fed on containing corn-soy basal diet(DF 5%) and high level(DF 6,7 and 8%) of dietary fiber diets for 7 weeks. Dietary fiber level of diet was make up by adding some alffalfa meal. Colored broiler meats were stored at 3$\circ$ for 24hr after skaughter, and used to analyze physico-chemical properties. Proximate component, pH, shear force value, myofibril fragmentation index, water holding capacity, cooking loss, protein extractability, fatty acid composition, Hunter's L, a value and palatability of cooked meat were not significantly affected by dietary fiber levels, whereas the Hunter's value of meat was significantly affected bty dietary fiber levels for the final period of feeding. Crude protein content, myofibril fragmentation index, water holding capacity, protein extractability and Hunter's b value of breast meat's were higher than thigh meat's, but crude fat content, pH, shear force value, cooking loss, palmitoleic acid, linolenic acid, and Hunter's a value were lower, regardless of dietary fiber level.
