A nutritional survey was made in 45 healthy Buddhist nuns (age : 20-34 yr) who have been vegetarians for more than 5 years and 20 female college students (aga : 20-22 yr) as a control group in Kyungpook province. Daily calorie intake of the Buddhist nuns and students were 1947 and 1815 kcal, respectively. The ratio of percent calorie of carbohydrate : fat : protein from total calories in the Buddhist nuns was 84 : 11 : 5 and that of the students was 70 : 15 : 15, respecting. The Buddhist nuns had significatly higher carbohydrate intake but markedly lower lipid intake than the students. Daily intakes of thiamin, niacin and ascorbic acid in the Buddhist nuns were higher, but those of iron, calcium and vitamin A were lower than the recommended daily allowances. Compared with the students, the Buddhist nuns had greater intakes of ascorbic acid, vitamin A, thiamin, niacin, and calcium. Anthropometric measurement showed that the Buddhist nuns had significantly higher values than the students in body weight, skinfold thickness, body surface area, and obesity index. There were highly significant correlations between anthropometric measurements and obesity index(0.55< r <0.99). On the other hands, correlation coefficients between nutrients intakes and skinfold thickness and obesity were very low(0.01< r <0.37). The Buddhist nuns and students showed similar normal values of hemoglobin concentration, hematocrit, and blood pressure.

The Dietary Reference Intakes (DRI's) are new nutrient intake standards that are being set for the United States and Canada. There are currently four types of DRI's: Estimated Average Requirements (EAR), Recommended Dietary Allowances (RDA), Adequate Intakes (AI), and Tolerable Upper Intake Levels (UL). The EAR is the nutrient intake that would be adequate for about half the population, while intake at the RDA should be adequate for 97-98% of the population. When the data are insufficient to set an EAR and RDA, then an AI is set. The UL is the highest intake level that does not pose a risk of adverse effects. The EAR, AI, and UL may be used to assess intakes of both individuals and of groups of people. For individuals, the EAR is used to calculate the probability that intake is inadequate, the AI is used to decide if the probability of inadequacy is low, and the UL is used to determine if a risk of excess intake is present. For groups. the EAR is used to estimate the prevalence of inadequacy, the AI is used to decide if the prevalence of inadequacy is low, and the UL is used to estimate the prevalence of excessive intakes. Because this approach to setting and applying nutrient standards is new, research recommendations include improving estimates of risk, improving dietary data, and improving statistical methods.

This study was longitudinally conducted to evaluate the intakes of protein, Ca, Mg and P of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty Korean lactating women and their infants during the first 3 months of lactation in Incheon area were participated. Protein, Ca and Mg, and P contents in the milk were determined using semimicro Kjeldahl (N ${\times}$ 6.38) , atomic absorption spectrophotometer and colorimeter, respectively, and also the milk consumption of the infants was measured by the test-weighing method. Protein contents of the milk were 1.96, 1.63, 1.51, 1.25 and 1.16 g/100 ml, and protein intakes of the breast-fed infants were 9.00, 9.85, 9.17, 8.97 and 7.76 g/day at 7, 15, 30, 60 and 90 days postpartum. The average protein intake per body weight of the breast-fed infants was 1.84 g/kg/day. The average intakes of Ca, Mg, P were 172.1 mg/day, 15.2 mg/day and 91.4 mg/day, respectively, and the average Ca/P ratio was 1.91. There was positive correlation between protein and Ca, protein and p, and Ca and P contents while negative correlation between Mg and P, The body weight of breast-fed infants increased normally from 3.6 $\pm$ 0.41 g at birth to three month during lactation. It is suggested that the breast-fed infants in Incheon area consume almost adequately protein, Ca and P from the milk compared with RDA for Korean infants.

It has been recognized that international food standards should be considered for a long time. The Codex Alimentarius programme initiated in the early 1960s has received valuable background documentation from the ICMSF (International Commission on Microbiological Specification for Foods) and also from ISO(the International Organization for Standardization). There has been a considerable move towards international harmonization of standards and methods of analysis. Many foreign countries recommend the guidelines for food microbiological standards quantitatively. To complement microbiological limits and tolerance levels for permissible number of defective samples, allowances should be made for sampling and other variations in laboratory methods. It may be necessary for guidelines of domestic food microbiological standards to be established so that the domestic food standards can be harmonized with foreign food standards. Food safety related microbiological guidelines of ICMSF, EU (European Union), UK (United Kingdom), China (Hong Kong) and Japan were reviewed and shown in examples.

This study was conducted to investigate the relationship between lactational capacity and intakes of energy and energy-yielding nutrients. Food consumption, intakes of carbohydrate, protein, fat and energy and quantity and proximate composition of milk of 11 lactating Korean mothers were determined at 1, 2 and 3 months postpartum longitudinally. Food consumption was estimated using a 24-hour recall method ; intakes of energy and energy-yielding nutrients were calculated according to the Food Composition Table. Daily milk production was estimated using a 72-hour test-weighing method ; protein, fat, lactose and energy concentrations were analyzed. Average intakes of energy and protein were 1974$\pm$386㎉/day and 67.0$\pm$12.3㎉/day, these were 73% and 74% of the Korean Recommended Allowances, respectively. Average milk yield was 720.1$\pm$123.3ml/day containing energy 59.6$\pm$9.5㎉/dl, protein 1.1$\pm$0.1g/dl, fat 2.7$\pm$0.8g/dl, and lactose 6.3$\pm$0.3g/dl. No relationship existed between the intakes of carbohydrate, protein, fat and energy and the quantity and proximate composition of the milk. However, the intakes of energy, carbohydrate and vegetable protein were inversely related to the concentrations of energy and lactose in the milk. This result indicates that lactational capacity may be affected by the other factors excluding intakes of energy and energy-yielding nutrients and a high intake of energy may not guarantee optimal lactational capacity.

Changes in nutritional and health status brought on by a two-year balanced diet were assessed with anthropometric measurements as well as hematological and lipid profiles in 56 healthy young men. Recommended dietary allowances (RDA) were adjusted with estimated daily weighted activity factor. The weighted resting energy expenditure factor of the subjects was 2.37 $\pm$ 0.05. Compared with RDA, all nutrient intakes were adequate and 56% of energy was supplied by carbohydrates, 18% by protein and 26% by fat. The vitamin and mineral intakes except vitamin B-2 were higher (26.46-129.88%) than RDA. Vitamin B-2 intake was 92.15 \ulcorner 14.16% of RDA. There was no seasonal variation on nutrient intakes. Height was increased and systolic blood pressure was decreased by balanced diet for two years. Body weight, diastolic blood pressure and body mass index (BMI) were unchanged. The level of hemoglobin and hematocrit was not changed, the level of plasma protein was decreased and the level of plasma total cholesterol and albumin was increased. These results suggest that a balanced diet can increase height and complement health status achieved through vigorous exercise, even in adults, and that the level of Korean RDA for energy is adequate to maintain existing body weight.

This study was to investigate 1) the correlation of serum Ca, with depression and anxiety ; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67 $\pm$ 0.15mg/d1 before the dietary treatment. They expressed severs depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32 $\pm$ 0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.

This study was longitudinally conducted to evaluate vitamin A intake of exclusively breast-fed infants compared with the Recommended Dietary Allowances (RDA) for Korean infants. Twenty-seven Korean lactating women and their infants during the first 6 months of lactation in Cheongju and Anseong areas were participated. Retinol and $\beta$-carotene contents in the milk were determined using HPLC and also the milk consumption of the infants was measured by the test-weighing methods. Vitamin A (retinol and $\beta$-carotene) contents of the milk were 65.7, 57.2, 48.1, 43.9, 38.2, 38.7 and 44.0 R.E./100 ml, and vitamin A intakes of the breast-fed infants were 361, 402, 348, 331, 304, 305 and 322 R.E./day at 0.5, 1, 2, 3, 4, 5 and 6 month of lactation, respectively. The average intake of vitamin A was 339.1 R.E./day and the percentage to RDA was 96.9% during 6 months. Vitamin A intakes per body weight of the breast-fed infants were 96.7, 88.3, 62.1, 50.0, 41.8, 39.3 and 39.6 R.E./kg/day at 0.5, 1, 2, 3, 4, 5 and 6 month. The body weight increased normally from 3.4 $\pm$ 0.5 kg at birth during lactation. It is suggested that the breast-fed infants in Cheongju and Anseong areas consumed adequately vitamin A from the milk compared with RDA for Korean infants.

This paper is to report our findings that vitamin B6 and folate nutritional state in the rural elderly population with alcohol dependency is poor. The present study was carried out to assess vitamin B6 and folate status in the 17 rural elderly subjects with alcohol dependency and 15 age-and sex-matched controls. Plasma and red cell folate concentrations were analyzed microbiologically, and pyridoxal-5-phosphate dependent erythrocyte alanine aspartate transminase(EAST) activity coefficients were determined using enzyme-coenzyme saturation kinetics. There was no difference in the amount of vitamin consumed between the two groups, and their intakes were 64% and 74.7%, respectively of the Korean dietary recommended allowances for vitamin B6 and folate. The mean percent activation for EAST of the total subjects was greater than 80%, suggesting an inadequate vitamin B6 status between the two groups. Folate concentrations in the red cell, but not in the plasma were significantly lower in the alcohol dependent(141.9ng/ml) subjects than that of the control(233.2ng/ml). Cigarette smokers had lower vitamin B6 and folate levels. Plasma and red cell folate levels were highest among the non-smoking, non-alcohol dependent subjects(11.7 and 257.3ng/ml, respectively) and lowest in the smoker-alcohol dependent group(6.7 and 132.9ng/ml). Finding ways to improve vitamin nutritional state such as vitamin supplementation might be necessary for the rural elderly people, especially for those with alcohol dependency.

The purpose of this study was to analyze and evaluate the menu served in business & industry contract foodservice by assessing nutritional value and by using menu-engineering technique from managers' view point. CAN-Pro program and Kasavana k Smith's Menu Engineering technique were used to evaluate the nutritional value and menu analysis, respectively. The data were analyzed using the SAS package program for descriptive analysis, t-test, ANOVA, and Pearson Correlation Analysis. As the result of nutritional value of lunch menu, all nutrient contents per meal were higher than a third of Korean recommended dietary allowances(RDA), But there was no problem when 20∼30% of plate waste was considered. Carbohydrate : Protein fat ratio was 62.7 : 16.4 : 20.8. Because animal : vegetable source ratios of protein, fat, calcium, iron were 44 : 56, 42 : 58, 22 : 78, 24 : 76, respectively, animal sources of calcium and iron needed to be supplemented. Plural set menus of A site were classified as STAR, PUZZLE, PLOWHORSE, DOG by Menu engineering technique. Set menus and soups & pot-stews among cafeteria menus in C site were operated properly without DOG and PUZZLE item. Side dishes of fishes, meats 8t eggs among cafeteria menus in C site were, for the most part, classified as STAR item, and side dishes of vegetables & salads and noodles among cafeteria menus in C site were STAR, PUZZLE, and DOG items.
