This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.
A study has been performed to estimate the average and high (90th percentile of consumers-only) daily intakes of sorbates by age-sex groups (> 3 years old) in Korea. The estimation of daily intakes was based on individual-based dietary intake data in ‘National Health and Nutrition Survey in 1998’and the contents of sorbates from samples. The estimated daily intakes (EDI) of sorbates for average consumers ranged from 0.09 mg/kg/bw/day to 0.51 mg/kg bw/day corresponding to 0.4-2.1% of acceptable daily intake (ADI). For high consumers, the range of EDI of sorbates was 3.42-14.65 mg/kg bw/day corresponding to 13.7-58.6% of ADI. Foods that contributed most to the daily intakes of sorbates for all age-sex groups were processed fish products, processed meat products, and salted floods. There was an inverse relationship between age and the consumption of sorbates for average and high consumers, whereas no marked pattern was emerged by sex categories. The intake levels of sorbates even among high consumers were below the ADI in Korea.
This study was performed to investigate dietary habits and nutritional intake according to body mass index (BMI) of female college students. The subjects were 1361 students with a mean age of 20.4 years residing in Seoul and Kyonggui area. BMI (kg/) between $\geq$ 18.5 to $\leq$ 23 was considered as nonnal, < 18.5 as underweight and > 23 as overweight. The subjects had a mean BMI of 20.0 kg/$m^2$ and 25% of them were classified as underweight group, 67% as normal group and 8% as overweight group. Dietary intake was assessed by food frequency method and consumption of foods and nutrients was analyzed. Frequency of meal skipping was higher in the overweight group, 16.1 % of the overweight group skipped dinner. Also, the frequency of snack intake was lowest in the overweight group. The overweight group consumed less meat and fish than the normal and underweight groups. The total number of foods consumed in a day was also significantly lower than that of the underweight and normal group. The overweight group consumed less energy, protein, fat, phosphorus and niacin than the underweight and normal groups. The overweight group took iron and sodium intake lower than the normal group. Mean intakes of nutrients except clacium and iron in all three groups were over Korea RDA. The NAR (nutrient adequacy ratio) value of all nutrients, except calcium, was lower in the overweight group when compared to the normal and underweight groups, and the MAR (mean adequacy ratio) of the overweight group was 0.89, which was lower than 0.92 of the underweight and 0.93 of the normal group. The above results indicated that the deficiency of major nutrients such as calcium and iron could be inducde by less kinds of consumed foods and frequent meal skipping including dinner in the overweighted group. Therefore, balanced nutrient intake is required to maintain skeletal health and prevent anemia in overweighted female college students aged twenties.
The purpose of this study was to investigate satisfaction and preference for current military meal service and food behaviors and food habits of some military personnel in Chunchen and Wonju of the Kwangwon area. The results are as follows. In the anthropometric survey, average height of the subjects was 175.03 $\pm$ 5.30 cm, average weight was 69.15 $\pm$ 7.74 kg. As a result of surveying satisfaction in the current food service, an item high in satisfaction was adequacy of serving hours, whereas an item of low satisfaction was diversity of menu. The item of food service improvement needs of the subjects were in order more variety of menu, nutrition, preference, sanitation, cooking method. As a result of surveying eating behavior of the subjects, most items were high medium response. They preferred soju and relish and also they liked the bokkum cooking method. As a result of surveying food habits of the subjects, items of good habits were regularity of meals, marginal meals, diversity of food intake, dairy and dairy products, avoiding too exciting meals and natural food diet; whereas, items of bad habits were fast food intake, alcohol, smoking, carbonated and caffeine beverages, skipping breakfast. snacks, fatty food intake, yellow or green vegetable intake and fruit and seaweed intake. Following is the result of a survey on the preference of meals by cooking method serving the current military meal service. They liked one-dish meals such as Bokkeumbap, Bibimbap, Tteokguk, whereas, they disliked curryrice, Jajangbap. In case of soup, they liked soup made from meat better than vegetable soup or soup made with fish. Also they liked pot stem better than soup. Generally they liked meals containing meat in most cooking methods. These results suggest that continuous and practical nutrition education to change food habits in military life are necessary to Prevent chronic disease with increasing age.
Sodium is a necessary element for the body. Excessive intake of sodium is known as one of the risk factors for chronic diseases. Recently, increasing numbers of people in Korea are suffering from chronic diseases. Major causes of deaths were chronic degenerative disease with the rising aging population. Especially, the population of rural areas is growing older fast. In rural areas, it is known that under nutrition and high sodium intake were major nutritional problems. For sodium intake, there were some studies about contributing food items. They were not enough to show diets relate to sodium intakes. Thus, this study analyzed dishes contributing to sodium intakes of elderly living in rural areas. Dietary intakes using "the 24hour recall method" were used. For the analysis for sodium intakes, "Can-pro3.0" was used. Ranking of dishes by contributions of sodium intakes were Korean cabbage, kimchi (19.6%), seasoned soybean paste (5.3%), soybean paste (4.6%), soybean paste soup dried radish leaves (3.5%), hot pork and kimchi stew (3.4%) in order. Ranking of dish groups by sodium intakes was kimchies (28.3%), soup and hot soups (22.8%), stews and casseroles (9.7%), seasonings (8.2%),and seasoned vegetables (6.0%) in order. One-dish meals among cooked rice, wheat noodles among noodle and mandu, soups using the soybean paste, stews using soybean paste and kimchi, salted fish among grilled foods, stir-fried anchovy among stir-fried foods, seasoned spinach, and Korean cabbage kimchi contributed to sodium intakes. As the nutrition deficiency of the elderly living in rural areas could be a problem, and excessive sodium intakes is threatening to their health, it is needed for the senior citizens to have adequate knowledge for diets containing less sodium. And recipes for healthy food and nutrition education based on their diets are needed.

This study was conducted to investigate the effect of dietary oxidized oil and ${\alpha}$-tocopherol level on growth and body composition of juvenile flounder. To prepare oxidized diets, squid liver oil was oxidized by aeration at $25^{\circ}C$ for 30 days. The six diets were prepared to contain 6% fresh or oxidized squid liver oil as the lipid sources in combination with three levels of ${\alpha}$-tocopheryl acetate at 0, 80 and 800 mg/kg diet. Triplicate groups of fish ($3.9{\pm}0.1$) were fed to apparent satiation twice a day for 8 weeks. Survival was not significantly different among treatments. Weight gain, feed efficiency, daily feed intake, protein efficiency ratio and condition factor of fish fed the fresh oil diets were significantly higher than those of fish fed the oxidized oil diets (P<0.05). The increase of the vitamin E level in diets did not result in any significant improvement on growth performance of fish fed both oil diets. The vitamin E content of the liver and dorsal muscle increased with increasing dietary vitamin E level at both oil diet groups. A decreasing trend in vitamin E content of the tissues was observed in fish fed the oxidized oil diets at the same dietary vitamin E level. Significantly higher moisture content and lower crude lipid content were observed in the whole body of fish fed the oxidized oil diets than fish fed the fresh oil diets (P<0.05). Dietary lipid source affected the fatty acid content of the whole body; higher contents of saturated and monoenoic fatty acids, and lower n-3 HUFA contents such as 20:5n-3 and 22:6n-3 were observed in fish fed the oxidized oil diets than those of fish fed fresh oil diets. The results of this study suggest that the dietary oxidized oil may impair the growth performance, and an increase in ${\alpha}$-tocopheryl acetate supplementation have no beneficial effect on growth and feed efficiency of juvenile flounder.
This study was conducted to compare an experimental extruded pellet (EP) and raw fish-based moist pellet (MP) on growth performance, whole-body and dorsal muscle composition, and textural properties of dorsal muscle for olive flounder Paralichthys olivaceus. Four groups of 8,000 fish (initial mean weight $27.1{\pm}0.05g$) per concrete tank ($10{\times}10m$) were fed the experimental diets for 16 months. After the feeding trial, no significant differences were observed in final mean body weight, weight gain, specific growth rate, feed intake, survival, and condition factor between EP and MP groups. However, feed efficiency of fish fed the EP was significantly higher than that of fish fed the MP. Moisture content in the whole-body of fish fed the MP was significantly higher than that of fish fed the EP. Significantly higher contents of polyunsaturated fatty acid (PUFA) in whole-body and dorsal muscle were observed in fish fed the EP compared with fish fed the MP. Any notable differences in amino acid contents or textural properties of the dorsal muscle were not observed in fish fed either the EP or the MP. The results of this study indicated that the EP could be developed to replace MP for the market size of production in olive flounder without the adverse effects on growth performance. Formulation of the EP could be used as a practical feed for olive flounder.

This study was conducted to investigate the utilization of defatted soybean meal as a substitute for fish meal in the diet for juvenile flounder (Paralichthys olivaceus). Duplicate groups of average weighing 35 g were fed one of four isonitrogenous ($54{\%}$) and isocaloric (575 kcal/100 g diet) diets containing $0{\%}, 10{\%}, 20{\%} and 30{\%}$ soybean meal for 45 days. Survival rates of all groups were $100{\%}$, Weight gain of fish decreased with increasing dietary soybean meal levels, However, this value was not significantly different between fish fed the control and $10{\%}$ soybean meal diet (P > 0.05). Feed efficiency and protein efficiency ratio decreased with increasing dietary soybean meal levels, but no significant differences were found among fish fed the control, $10{\%}\;and\;20{\%}$ soybean meal diets (P > 0.05). Daily feed and protein intake increased with increasing dietary soybean meal level. Crude protein and moisture content of liver tended to decrease and crude lipid content tended to increase with decreasing of dietary soybean meal levels. Plasma total cholesterol levels of fish fed the diets containing $20{\%}\;and\;30{\%}$ soybean meal were significantly lower than that of fish fed control diet (P < 0.05), Plasma GOT level significantly increased with increasing dietary soybean meal level (P < 0.05). It is concluded that soybean meal can be used as a partial substitute for fish meal up to $10{\%}$ in this dietary formulation for growth of juvenile flounder.

BACKGROUND/OBJECTIVES: Despite the importance of a low-iodine diet (LID) for thyroid cancer patients preparing for radioactive iodine (RAI) therapy, few studies have evaluated dietary intake during LID. This study evaluated the amount of dietary iodine intake and its major food sources during a typical diet and during LID periods for thyroid cancer patients preparing for RAI therapy, and examined how the type of nutrition education of LID affects iodine intake. SUBJECTS/METHODS: A total of 92 differentiated thyroid cancer patients with total thyroidectomy were enrolled from Seoul National University Hospital. All subjects completed three days of dietary records during usual and low-iodine diets before $^{131}I$ administration. RESULTS: The median iodine intake was $290{\mu}g/day$ on the usual diet and $63.2{\mu}g/day$ on the LID. The major food groups during the usual diet were seaweed, salted vegetables, fish, milk, and dairy products and the consumption of these foods decreased significantly during LID. The mean energy intake on the LID was 1,325 kcal, which was 446 kcal lower than on the usual diet (1,771 kcal). By avoiding iodine, the intake of most other nutrients, including sodium, was significantly reduced during LID (P < 0.005). Regarding nutritional education, intensive education was more effective than a simple education at reducing iodine intake. CONCLUSION: Iodine intake for thyroid cancer patients was significantly reduced during LID and was within the recommended amount. However, the intake of most other nutrients and calories was also reduced. Future studies are needed to develop a practical dietary protocol for a LID in Korean patients.
