The nutritional status is strictly related with flood production, flood processing, and distribution along with habits, education and technological achievement, adapted and adjusted to socio-economic conditions. All these factors are independently affecting the nutritional status of populations. In addition to the above mentioned factors launch of it is useful to consider two points ; unification of the South and the North Korea and WTO. The present study gives and overview of basic knowledge about nutritional status of Korean by using availab1e data in relation to nutrition. The basic characteristics of Korean diet with proportions high in carbohydrate and low in fat, have been relatively constant for the past two decades. The average daily flood intake in terms of weight of flood per person is relatively constant throughout the years. Although the proportion of animal food intake tends to increase recently, the Korean diet is still insufficient in meat, eggs, milk, and fish. Moreover because milk has not been accustomed flood with the general population and not much used in traditional flood preparation in Korea, milk consumption was especially low in comparison with western countries. The total energy intake was relatively constant throughout the years from 1969 to 1993. However, changes in the composition have occurred in the past two decades. The amount and proportions of fat have been s1ightly increasing while the total amount of carbohydrate has been decreasing. The nutrition preblems of Korea have changed over the past severa1 decades. The general adequacy of protein and energy existing after Korean War(1950) was resolved now. Since then the average diet appears to be nearly desirable in terms of rapid rates of growth during childhood and attainment of progressively stature and body weight at maturity. The dietary habits of some young people in these days seem to be taking a more western style diets. This trends if established by habit may lead to a marked change in the traditional diet and health. I think Korean nutritional experiences have potential values for tole other countries in Asia and in western countries. Korean diet illustrates a high level of nutritional status and health attainable will a largely vegetable diet : high in complex carbohydrates, and dietary fibre, and low in tat, and reasonable amount of total protein. This is significant for developing and developed countries that must select specific goals fir adequate nutrition for the people. Compared to the western countries, Koreas different incidence of coronary heart disease and malignancy demonstrates the significance of environment and probably the prominent role of diet in the development of these diseases. The changes occurring in the Korean diet of fir the unusual opportunity to assess the effect of diet upon chronic degenerative disease. In the future, the Korean diet might be continue to change significantly These changes are being influenced by socioeconomic factors that have been emerging and growing stronger since mid-l980 and that probably continue to be potent. The expanded purchasing power of the consumer results in increased discretionary purchases. In the case of foodstuffs, the consumer demands appear to be directed toward items of higher protein content, which, being primarily animal products, are inevitably accompanied by an increased consumption of fat. The continued availability of these more expensive flood items depends upon the balance of foreign trade favouring their importation and domestic production. A regression of foreign trade could result in a decreased supply for the consumer, whereas continued growth of trade iou]d provide freedom for increasing availability to the consumer. In this latter situation the exact choice of foodstuffs is depending upon comsumer tastes and the pressures that may influence it.

This study was conducted to evaluate the nutrition quality of the commercial infant formulas and to seek the solution to the establishment of the standard of nutrient requirements for infant formula in Korea. Nutrition informations were obtained from the labels of nineteen commercial infant formulas manufactured by 3 different companies, and the actual amounts of some nutrients were analyzed and compared to the labeled amounts. In addition, the nutrient composition of the commercial infant formulas was compared to the composition of breast milk, RDA for infants, and Codex standard for infant formula. The kind of minerals, vitamins and special components added to the commercial infant formulas were the major differences among 3 manufacturers. For some nutrients, the analyzed amounts were lower than the labeled amounts. In addition when different batches of the same kind of infant formula were analyzed, the large variations in the amounts of certain nutrients were noted. These data suggest that the nutrition labeling informations need to be validated, and nutrients added to the formulas are to be homogenized thoroughly. In order to solve these problems, therefore, like other countries, we need to establish the standard of nutrient requirements for infant formulas. Considering the available data on breast milk composition, RDA for infants and coordination with the international standard, we suggest the adoption of the Codex standard for infant formula may be the best way to manage the nutrition quality of commercial infant formulas at the present time.

This study was undertaken to determine talc fatty acid intakes of lactating women and breast fed infants. Food consumptions of lactating women were measured at 3 4nd 9 days find 4, 8 and 12 weeks postpartum, respectively and diet samples were collected at the same time. Breast milk and blood samples were collected at 12 weeks postpartum. Fatty acid profiles of diet and breast milk were analyzed with GC. Total fatty acid intakes, fat percentage of energy, P/M/S and n-6/n-3 ratios of lactating women were 50.7 g/d, 20.9$\%$, 0.6/0.9/1 and 4.0/l, respect timely, over the first 12 weeks of postpartum and were not significantly different according to the lactating stages. Total fatty acid intakes and fat percentage of energy of the infects aged 12 weeks through the breast milk alone were 18.9 g/d and 44.8. This study shows that the linoleic acid percentage of energy intake in infants was 6.7$\%$, which was in optimum and/or high level to generally recommended guideline. DHA intakes of lactating women were positively correlated with those of infants from breast mil.

This study was carried out to investigate growth performance, energy and protein metabolism of breast and formula fed infants from birth to 3 months postpartum. There were four groups : breast fed(BF) and three formula fed groups(FFM, FFN and FFP). There was no significant difference in the height of infants according to feeding method and formula brands. However, mean weight of FFM was significantly higher than that of FFP and BF at 1 and 3 months postpartum, respectively. Mean head circumference of FFN was lowest among groups. The average intake of breast milk was $781.4{\;}{pm}{\;}119.3m{\ell}/day$ and that of formula was $848.6{\;}{pm}{\;}118.5m{\ell}/day$. Mean apparent digestible energy intakes of formula-fed infants and breast-fed infants during 3months were 568.9 $\pm$146.9 kca1/day and 657.9$\pm$212.8 kca1/day, respectively. The average protein intake of brest-fed and formula-fed infants were 8.3$\pm$1.6g/day and 14.1$\pm$14.1 g/day, respectively. The protein intakes of formula-fed infants were significantly higher than those of breast-fed infants at 1, 2, 3 months. The apparent protein digestibility of breast-fed infants was singnificantly higher compared to formula fed infant. These data suggest that RDA for infants be established and breast feeding be encouraged.

Correlations of adolescents' blood pressure with dietary factors and blood or urinary electrolytes were investigated in this study. Through the screening for blood pressures of 960 middle school students aged 13-16 years, 30 students with the mean value of SBP and DBP above 96th percentile(high blood pressure group) and the other 30 with the mean blood pressure between 48th and 52th percentiles(normal blood pressure group) were selected as the subjects. SBP/DBP of the high and talc normal blood pressure groups were $141.8{\pm}9.0$ / $83.6{\pm}5.1$ mmHg and $116.4{\pm}3.5$ / $69.8{\pm}3.7 mmHg$, respectively. The average values of age, weight, height, BMI, degree of relative crude physical activity, and family income were not different between two groups. Among nutrients for which intakes were determined by 24 hour-recall and expressed as percent RDA, intakes of total and animal calcium were lower in the high blood pressure group compared to the normal, and were negatively correlated with both SBP and DBP even when the effects of related general and other dietary factors were excluded. Whereas energy, total, animal and vegetable protein, total and animal lipid, and riboflavin were higher in intake in the high blood pressure group than in fille normal, and they were in positive correlations with SBP and/or DBP. Vitamin A and ascorbic acid intakes were also negatively correlated with DBP, though ascorbic acid intake was not different between two groups. High blood pressure group preferred higher concentration of thin rice gruel than normal group and talc preferred salt concentrations was ill positive correlation with SBP. Serum and urinary levels of Ca, Mg, Ca/Mg ratio, Na, K and Na/K ratio did not show any differences between two groups. However serum Ca/Mg retio was in negative and se겨m Mg was ill positive correlations with SBP, and urinary Na excretion was negatively correlated with SBP. Calcium intake showed negative correlation with serum Ha and Na/K ratio. Our data indicated that dietary intake of Ca, energy, protein, lipid, vitamin A and C as well as salt preference were associated with blood pressure in adolescents. It might be assumed that Ca lowered blood pressure by increasing serum Ca/Mg ratio and decreasing serum Ca/K ratio though urinary excretion of Na.

This study was conducted to compare the dietary factors which influence on the bone status of 28 women in urban and 30 women in rural area. Urinary excretion of hydroxyproline(Hpr) and Calcium(Ca) were measured as biological markers of bone resorption. Mean daily intake levels of total protein, animal protein, total calcium, calcium, calcium from milk and milk products, animal calcium, Ca / P ratio by 24 hr recall method were significantly higher in urban women. However, mean daily sodium(Na) intake levels were not significantly different between two groups. Ca Index score and Na Index score by food frequency methods were also significantly higher in urban than in rural subjects. While urinary Ca excretion elves of two groups were similar, Na excretion levels were significantly higher in rural women. Mean urniary levels of Ca / creatinine(cr) and Hpr / cr as bone status index were within normal range and not significantly different between two groups. However, prevalence of poor bone status as assessed by hydroxyproline was higher in rural women. Na Index, urinary Ca excretion and Ca / cr ratio were significantly correlated with bone status(Hpr / cr) in urban women, while only age was related to bone status in rural women. These demonstrated that high Na intake results in increased urinary excretion of Na and Ca and could cause bone resorption. Multiple regression analysis indicated that Na Index score and age have greater effect than other variables in urban women and only age has greater effect in rural women.

This study was conducted to assess nutritional status of the elderly from low-income urban area and to investigate environmental and health risk factors that may influence to nutrient intakes. One hindered eighty three(males 53, females 130) healthy homestaying subjects aged over 65 years in Seoul were assessed with anthropometric measurements and dietary intake in August, 1994. HT and BW for females were decreased with aging. The proportion of hypertension was 36% with indite of $SBP{\;}(SBP{\;}{\gg}{\;}160mmHg)$ and 52% with indice of DBP $(DBP{\;}\gg{\;}97mmHg)$. Distribution of BMI, OR and PIBW indicated that BMI was more sensitive for identifying underweight whereas PIBW was more sensitive for identifying overweight. for group aged over 75, males had significantly lower intake of energy, protein, fat, calcium, iron, vitamin A and $\beta$ carotene compared to the group aged 67~74, while females had lower intake of calcium and vitamin A. Elderly group with smoking, less familly size and living alone had lower nutrient intakes. Blood pressure in the elderly subjects did not influence to nutrient intakes, except elderly with normal blood pressure were taking increased amount of thiamin and niacin.

This survey was carried out with Choongbuk university students to study their nutrition knowledge, dietary altitudes, and flood behaviors, in September, 1994 It showed women had more nutrition knowledge, more positive dietary altitudes, and ate various floods mort frequently. Students boarding themselves had poor food behaviors. There were positive relationships between nutrition knowledge and dietary attitudes, and dietary attitudes and flood behaviors. More reasonable nutrition education is needed far desirable food behaviors.
