  • The purpose of this study was to evaluate the meal pattern and the nutritional balance in university foodservices of Seoul. The survey was conducted using a questionnaire with 317 students at five different cafeterias that served 23 meals. We weighed all the meals offered by the university foodservices, separated the foods, and calculated their nutritional content using a computer program $\ulcorner$DS24$\lrcorner$. We also checked the dishes and those amount students consumed from the menu. The results of this study is summarized as follows. : 1) The most prevalent menu patterns included rice, soup, two side dishes, and kimchi. 2) Most nutrient contents per meal in a given menu was lower than one third of the recommended dietary allowance(RDA). 3) The mean energy content for the amount of rice that was served was 399㎉, for the side dish, it was 107㎉, and for the kimchi, it was 9.9㎉. 4) The number of total dishes and side dishes was five and two, respectively. The dietary variety score was 16.7, and the dietary diversity score was 3. 5) The mean energy intake by students at self-operated managements were 545㎉, and at one contracted management, the energy intake were 494㎉. Both of them did not serve enough to meet one third of the RDA. Nutrient adequacy ration(NAR) was 0.4∼0.9, and Index of nutritional quality(INQ) was above 0.9 for most nutrients with the exception of calcium and vitamin B$_2$.

  • This study was done to investigate the 12 college volleyball player's food behavior, nutrient intakes, and their serum lipid levels during the periods of training and detraining and to provide basic data for an effective program for the volleyball players during the period of detraining after the game season. The results were summarized as follows : The total daily energy intake of the players was $3,363{\pm}339kcal and 3,692{\pm}499kcal$ during the periods of the training and detraining, respectively. During the training period, daily intakes of protein, calcium and vitamin A, and $B_2$ were lower than the recommended dietary allowance for the players. During the detraining period, the players' daily intakes of calcium, iron, and vitamin A were even lower. However, the consumption of alcohol was dramatically increased during the period of detraining. The levels of serum triglyceride and very low density lipoprotein were significantly increased during the detraining period. Basal metabolic rates were significantly increased after the training period and diastolic pressure was decreased during the detraining period. In conclusion, out results suggest that the detraining of volleyball players for 10 days after intensive training, negatively affects their food behavior and serum lipid concentrations. Therefore, for the improvement of performance for the next game season, a planned program for the players' detraining period should be developed.

  • This study was conducted to determine the influence of alfalfa supplementation on intake, digestibility nitrogen and energy utilization in Korean native goats fed oak browse. This experiment was conducted by total collection method in laboratory, 1994. Diets included 100% oak bmwse(control), 75% oak browse+ 25% alfalfa and 50% oak browse + 50% alfalfa. Alfalfa supplemented diets were slightly higher CP(PO.O5). lignin (P<0.05) and tannin(P<0.05) contents than those control diets. Increasing levels of alfalfa supplementation, dry matter intake slightly increased, but no differences were observed in all diets. Digestibility for dry matter and cellular constituents showed higher for alfalfa supplemented diets than control diets(P<0.05), but NDF and ADF digestibility were similar for all diets. Alfalfa supplemented diets furnished higher dietary N, apparently digested N and retained N than did the control diets(P<0.05). Consumed energy slightly increased with increasing levels of alfalfa supplementation(P>0.05). DE was high(P<0.05) in alfalfa supplemented diets. but ME was similar for all diets. As above results, oak browse diets alone did not supply N and energy in excess of NRC recommended allowance for goats. Hence, goats fed oak browse with supplementation of protein sources such as alfalfa will be need to provides adequate nutrients.

  • Purpose: This descriptive study aimed to compare the perception of the acceptable foods for the neutropenic diet between nurses and patients by food type. Methods: The participants were 225 nurses working at chemotherapy wards and 71 patients in chemotherapy treatment. Data were collected with a self-administered questionnaire from January 2 to February 24, 2012, and analyzed with SPSS 12.0 program using descriptive statistics and the ${\chi}^2$-test. Results: Eighty-eight point eight percent of nurses and 76.1% of cancer patients thought the patients needed the neutropenic diets. The most important decisional criteria to determine dietary restriction was neutrophil count for nurses and food type for patients. The two groups showed significantly different allowance to raw fruits and raw vegetables, sterilized canned juice, fried vegetables, yogurt, uncooked tofu, salted fish, cooked fish, cooked shellfish, uncooked grain powder, jellified food, home-made bread/cookies, nuts including peanuts, instant coffee or tea and tea brewed. In general, patients were more permissive about the neutropenic diet than nurses. Conclusion: It is recommended to consider patients' preference as well as nurses' professional knowledge and publish standardized clinical diet guidelines for neutropenic patients with collaboration between nurses and patient representatives.

  • The purpose of this study is to investigate zinc and copper intakes of exclusively breast-fed infants. We measured consumed volume and the minerals concentrations of human milk from thirty three lactating women and their infants during the first 5 months of lactation , Zinc concentrations of human milk showed 0.394, 0.290, 0.191, 0.147 and 0.139mg/100g at 0.5, 1, 2, 3, 4 and 5 months of lactation respectively. Copper concentrations in the milk showed 61.04, 45.97, 37.15, 3.94, 26.22 and 26.21$\mu\textrm{g}$/100g respectively. Consumed volume of the milk of infants were 515, 650, 718, 731, 746 and 769g/day. There is significant difference between boys and girls in consumed volume of the milk at 2, 3 and 4 months of lactation. Zinc intakes of breast-fed infants declined(p<0.05) from 2.13mg/day at 0.5 months to 1.21mg/day at 3 months with no change thereafter significantly. Copper intakes of the infants declined(p<0.05) from 323.2$\mu\textrm{g}$/day at 0.5 months to 238.9$\mu\textrm{g}$/day at 3 months with no change thereafter. Form this survey, the reevaluation of zinc and copper intakes and recommended dietary allowance of those minerals during infancy are merited. (Korean J Nutrition 33(8) : 857-863, 2000)

  • The effects of environmental agents on health are great concern for all. It was recognized that each human has differential susceptibility to environmental effects. Susceptibility are changed by many factors includin gdevelopmpntal processes, genetic factors, nutritional stratus, preexisting disease conditions, life style and personal habits. Of all factors nutritional factors seem to be the area most modifiable. Consequently, It is an area that must be more thoroughly evaluated. In this paper, nutrient and environment interactions are reviewed briefly with published literatures. This paper deals with the influence of micronutrients(energy, protein and fat), Vitamins (vitamin 4, vitamin B-complex, vitamin C, vitamin D and vitamin I) and Minerals(calcium, iron, selenium, zinc and other minerls) on environmental effects. The role of arch nutrient was assessed in modifyine the expression of environmental pollutant toxicity with available litertures. In each nutrient section, the effect of environment was considered in following agents : heavy metals(lead, cadmium, mercury, silver and etc), inorganic agents(nitwits, sulfite, fluoride and etc), organic agents(benzene, carbon tatra-chloride, aflatoxin, auto dye, dialbrin etc), Irritant gas(ozone, carbon monooxide and etc), physical agents(X-irradiation, ultra violet, temperature and noise) and insectcides. The extent to which nutritional status modifies environmental effects 3nd its converse, how envirollments affects nutritional status is very complex. In deed, at the present time there are more than 50 chelnical/phycical agents that affect the nutrient metabolism and/or have their toxicity either directly diminished or enhanced by nutrients of those agents, small number of agents for each nutrients have sufficient evidence to warrant any reasonable degree of confidence in their hypothesized associtation. With these information at this present time it is hard to conclude that the recommended dietary allowance for each nutrient should be reconsidered.

  • Timing of weaning is later in Korean rural and lower urban classes compared with middle and upper classes. Weaning after the international standard of six months of age has adverse effects on the growth rate of children. This occurs because supplementary foods are not provided for the child during the weaning period; rather, the infant goes directly from nursing(or bottle feeding) to the cereals and solid foods of the adult diet. Consequently, all nutrient and calorie intake, with the exception of thiamin, in Korean rural children had not yet attained the Recommended Dietary Allowance (RDA). This situation bas created an urgent need for easy to prepare, low priced. highly nutritious supplementary foods. The research team of Yonsei University developed 3 formulas prepared from rice, soybeans, sesame, dry skim milk and fish which are all plentiful and inexpensive items in Korea. A proximate analysis and amino acid determination were performed on three formula. These formulas were prepared and used as exprimental diet for an animal assay. In the animal assay, growth rate, PER evaluated and biochemical analyses were also carried out. A safety storage assay and the cost evaluation were also conducted.

  • A vitamin B-6 (B-6) intake higher than the current Recommended Dietary Allowance (RDA) has been found to provide an improvement in immune system. Seven premenopausal women consumed their usual diet with the exception of foods relatively high in vitamin B-6 for a total of 27 d. After 7 d, all subjects received a multivitamin supplement containing 2mg B-6 and 4 subjects were given an additional 50mg of B-6 supplement for 20 d. Lymphocyte response to phytohemagglutinin (PHA) was measured before and after the supplementation. To determine the effect of different forms of B-6 on lymphocyte proliferation, cell culture media supplemented with pyridoxal (PL) and PLP, as well as B-6 free media, were tested. A 50mg B-6 supplement significantly increased vitamin B-6 status. There was no further enhancement on lymphocyte proliferation when subjects were taking an additional 50mg of vitamin B-6 supplement. In general, lymphocyte proliferation in media with either PLP or PL did not show any prominent difference. These [m-dings suggest that there may be no further benefits of a B-6 dose beyond twice that of the current RDA on lymphocyte proliferation. Further studies are necessary to examine the effect of the B-6 intake level on activities of enzymes involved in cellular B-6 metabolism in lymphocytes to provide substantial insight into the mechanisms underlying the role of B-6 in the lymphocyte proliferation.

  • In this study, the contents of soluble vitamins B1 (thiamin), B2 (riboflavin), and B3 (niacin) in 13 kinds of rice, 11 kinds of noodles, and 15 kinds of sauces were identified. The limit of detection (LOD) and limit of quantification (LOQ) were checked to determine the reliability of the experimental results, and the accuracy of the results through the standard reference material (SRM 1849a) was verified to show excellent indicators. As for thiamin, japchaebab (stir-fried glass noodles with rice) was found to contain the highest content among rice dishes, makguksu (buckwheat noodles) among noodle dishes, and tomato spaghetti sauce among sauces. Riboflavin was identified as having the highest content in slightly spicy jajangbab (black-bean sauce with rice), bibimguksu (spicy noodles) for noodles, and spicy curry with turmeric for sauces. Niacin was highest in content in the deep and rich flavors of spicy chicken-fried rice, janchiguksu (banquet noodles), and black-bean sauce, respectively. As a result of checking the amount of recommended daily intake of water-soluble vitamins for Korean adult men and women, the highest content of riboflavin was 217.40% for men and 271.75% for women. Through this study, we are going to establish a database of nutrients for the water-soluble vitamins contained in rice, noodles, and sauces to provide the necessary dietary data concerning the content of the water-soluble vitamins contained in foods for daily recommended intake.

  • The purpose of this study was to compare the nutrient intake and foodservice satisfaction of homebound elderly had lunch at the local community centers by the difference of meal service charge. Two local community center with cons-regate meal service program located in Daegu and Gyongsan were selected; one with free of meal service charge (F), and the other with 500-1,000 won for meal service charge (K), According to the dietary assessment, energy and nutrient intakes of the 156 elderly subjects were as a whole under the Korean Recommended Dietary Allowance (RDA). Elderly or F service conte. showed higher $\%$ RDA for the selected nutrients and MAR (mean adequacy ratio) than those of K service center (p<0.001). Participants were satisfied with most of the congregation meal service from community conte. with different reasons such as 'tasty (K service center)' and 'free of charge (F service center)'. In conclusion, elderly had the lunch at the community center with free of meal service charge was poor nutrition status and lower socioeconomic level than the other type of community center in this area. Therefore, healthy menu for elderly should be developed and managed by professional dietitian, as well as its impact on health status of this group, and congregate meal service system might be extended to the homebound elderly of whole community with free of charge.
