The study was designed to observe the correlation between the eating habits and growth development in 1,574 children (3-6 years old) in Kyunggi-do and Seoul, Korea. The eating habits and nutrient intake were determined by mini dietary assessment and food frequency questionnaire (FFQ). 35.6% children had been practicing an unbalanced diets. Children with unbalanced diet consumed less amount of protein source foods (meat, fish, egg, soy products), vegetables and fruits and had irregular meal time, but more of them preferred sweet foods (ice creme, cookies) and carbonated drinks as snack compared with children in balanced diet. 24-35% children consumed energy, iron (Fe), calcium (Ca), Niacin, Zinc (Zn) less than 75% RDA. Energy intake of children with unbalanced diet was not significantly different from those with balanced diet, but they consumed less amount of niacin, Fe, Ca and Zn than those with balanced diet. By using the relative percentage of standard weight-length-index (WLI), 65.7% children was normal weight, 12.9% was underweight, 13.4% was overweight and 7.9% was obese. However, 11.9% of underweight and normal weight children was so called thin obese since their body fat content was greater than 20%. There were 16.8% underweight in children with unbalanced diet and 12.6% underweight in those with balanced diet. Compared to normal weight, the underweight children significantly consumed less amount of milk and its product, high protein foods, fried foods and fruits, but obese children consumed more high protein source foods (meat, fish, egg, etc) and sweet foods. In conclusion, the eating habits of unbalanced meal was prevalent problem in preschool children which resulting in their health risks. Therefore, it would be needed that new approach for nutrition education to improve eating habits in preschoolers.

This study examined the nutritional information using the nutrition labels of gimbap sold at convenience stores and evaluated nutritional adequacy compared to dietary reference intakes for Korean adolescents. Thirty gimbaps (triangular gimbaps and regular gimbaps according to the main ingredients of vegetables, fish, and meat) were purchased at five convenience stores of different brands with many stores in Korea. The food and nutrition labels of the gimbaps were investigated, and nine minerals were analyzed using inductively coupled plasma-mass spectrometry (ICP-MS). The average price of gimbap was 1,906.7 won, and average energy was 292.0 kcal, and the protein content was 15.5% of the recommended intake for Korean male adolescents aged 15~18 years. The mineral content ranged from 6.9% for zinc to 39.0% for selenium. Except for sodium and selenium, the energy, protein, and mineral content did not meet 1/3 of dietary reference intakes for adolescents. For the index of nutritional quality (INQ), calcium and zinc were the lowest in the triangular and regular gimbap, respectively. The INQ of potassium was significantly higher in triangular gimbap with vegetables. The content and INQ of selenium were in regular gimbap with fish, and the zinc INQ was in regular gimbap with meat. Overall, gimbap sold in convenience stores has a high sodium content, and the contents of energy, protein, and minerals, except selenium, are insufficient for a single meal.

Although flounder is one of the most important marine fish for aquaculture in Korea, feeding the flounder in commercial farms depends mainly on moist pellet in which over 70% frozen fishes (e.g. frozen horse mackerel) are incorporated in its formulation. Therefore, for further expansion of flounder farming, it is essential to employ practical formulated feeds that can support reasonable growth. Development of nutritionally balanced and cost-effective feeds is dependant on the information about nutritional requirement and feed utilization of the species. Nutrient and energy source in feed are needed for the growth and maintenance of fish. Protein is probably the most important nutrient affecting fish growth and feed cost. Therefore, it is essential to determine the optimum dietary protein level for the growth of fish, both its high proportion in the feed and because it is the main factor in determining feed cost. Dietary energy level is also critical because protein source in the feed is utilized as an energy source when the feed deficient in energy is fed to fish, whereas when the feed excess in energy is fed to fish, feed consumption decreased and resulted in growth reduction due to lack of other necessary nutrients for normal growth. Improper dietary protein, energy levels and/or their ratio will lead to an increase of fish production cost and deterioration of water quality resulting from wasted feed; thus, they are important in formulating commercial feed. Dietary lipids play important roles in providing energy and essential fatty acid for normal growth and survival of fish. Although carbohydrates are not essential nutrients for carnivorous fish, these compounds play important roles as a low-cost energy source for protein sparing and also as a feed binder. Nutrition researches for flounder have identified its requirements of protein, lipid and essential fatty acid, vitamin, and minerals for normal growth. Other studies have also been carried out to investigate the utilization of the protein, lipid and carbohydrate sources. Based on these nutritional information obtained, practical feed formulations have been studied for improve aquaculture production of flounder. The results of the researches on utilization of dietary protein, lipid and carbohydrate by flounder are discussed in this review.

The interaction of myofibrillar protein with lipid or oxidized lipid was considered to be mostly contributing to the drop of digestibility of fish meat products. The digestibility of myofibrillar protein was $92.11\%$ for flounder and $88.04\%$ for hairtail fish, repectively, and as a rule it decreased as both the amount of lipid and reaction time increased. It also decreased with increase in the amount of added linoleate and oxidized linoleate. However, when the reaction continued for 6 hours or more the digestibility rather increased, which was provably due to the unfolding of protein structure. The hot air dried hairtail fish showed the lowest C-PER values among all dried fish products. The protein quality of flounder, hairtail fish and their dried ones except hot air dried ones measured by C-PER procedure were superior to that of ANRC casein. DC-PER values of all samples were greater than those of C-PER values and the greater discrepancies were noted in hairtail fish (fatty fish) products which possessed the lower in vitro protein digestibilities. Predicted diegstibilities, which were calculated using amino acid profiles, of all samples except raw ones were overestimated in comparison with in vitro protein digestibilities. From the observations so far, formation of complex of lipids and protein was thought to be the most important factor in lowering protein digestibility of the dried fish meat products.

This study investigated the food quality characteristics of mottled skate Raja pulchra including the proximate composition, taste, color, flavor and texture as affected by area caught (Heuksando and Daecheongdo), sex and fish weight (heavy, intermediate and light grades). Based on viable cell counts, all of the mottled skates studied remained fresh. The moisture and protein contents of the mottled skate did not differ by the area caught and fish weight, but differed by fish sex. The taste of mottled skate was affected only by fish weight. The texture of the mottled skate differed according to fish sex and fish weight. The odor intensity did not differ for the three parameters.

This study was carried out to investigate preference and perception of seafood among soldiers on cook's duty in military meal service. 58.9% of the respondents answered that they liked seafood and the major eating place were in their home(48.0%) and in the restaurant(40.4%). The favorite seafood cooking methods turned out to eat as raw fish, to grill, to stew, to fry in order. In comparison with the meat dishes, seafoods were considered superior to meat in nutritional value but evaluated inferior to meat in the aspects of sanitation and tasteless problem. 32.9% of the respondents answered they liked seafood dishes in military meal service and they disliked them because of taste or cooking method of the seafood. They liked fried or grilled seafood in military meal service. The plate waste amounts of the seafood menu were more than half in almost every surveyed menu and reasons for plate waste were fish smell and taste problems. The difficulties of cooking seafood in military meal service were breaking down of seafood during cooking and complexity of cooking. They scored seafood higher than average in nutrition, taste, diversity of cooking method and aspect of health. On the basis of the results above, introducing diverse cooking methods and menu are suggested and education of cooking skills and development of cooking facilities are needed in military meal service.

The purpose of this study was to investigate dietary habits and food compliance in stroke patients. One-hundred sixty eight elderly stroke patients and 97 young patients with first -ever stroke admitted to Asan Medical Center between 1994 and 1998 were studied. Using a structured interview, we assessed food intake. food consumption frequency and compliance to low salt, low meat hight fish and high fruit and vegetable diets. These results were analyzed with X$^2$, t-tests, and analysis of variance (ANOVA) using the SAS package program. Salted food intake and cholesterol-containing food frequency were increased whereas frequency of fruits and vegetables intake was decreased in young stroke patients compared to the elderly. Meat intake and cholesterol-containing food frequency were increased in the males compared to the females in elderly stroke patients. and fish intake and cholesterol-containing food frequency were higher in the males than the females in the young. In patients with high economic status, frequency of fruits and vegetables was elevated. Also compliance the low meat and high fruit and vegetable diet in young patients was lower than that in the elderly. When the life-style risk factors influencing the food intake of frequency of fruits and vegetables was affected by education in young stroke patients. In elderly stroke patients, meat intake frequency of cholesterol-containing foods and fruits and vegetables were influenced by sex and /or income. Our results suggest that dietary intake of salt meat ,cholesterol-containing foods. fruits and vegetables in stroke patients may vary with age, sex the presence of risk factors or economic status therefore guidelines and nutrition education should by formulated to prevent stroke recurrence based on dietary habits and risk factors of individual patients.

This study examined the time course effects of conjugated linoleic acid (CLA) on the body weight, adipose depots and lipid profiles of ICR male mice using two different sources of fats in the diet Ninety eight mice weighing 25 to 30 g were divided into four groups: beef tallow (BT) and fish oil (FO), beef tallow with CLA supplementation (BTC), and fish oil with CLA supplementation (FOC) group. Eight to nine mice in each group were fed with the experimental diets for 1, 2 or 4 weeks, respectively. All mice were fed experimental diets containing $12\%$ of total dietary fat (w/w) with or without $0.5\%$ CLA (w/w). CLA supplementation did not affect the body weight The weight of epididymal and visceral fats were significantly lower in BTC compared to those in BT groups during the periods examined (p<0.05), whereas they were significantly lower in FOC than those in FO only at 4 weeks (p<0.05). The levels of triglycerides in the plasma were significantly decreased in the BTC group than in BT group throughout the experimental periods (p<0.05). But, FOC was only effective at 4 weeks as compared to FO. The levels of total cholesterol and HDL-C were significantly increased in the BTC than in BT during the entire period (p<0.05), whereas there were no difference between FO and FOC on the levelsof total cholesterol and HDL-C. The levels of free fatty acids (FFA) were significantly decreased in BTC than in BT at 1 and 4weeks and in FOC only at 4 weeks as compared to FO (p<0.05). Taken these results together, CLA was more effective in the beef tallow diet in lowering the epididymal and visceral fat weights and triglyceride level rather than fish oil diet with CLA. Furthermore, the effect became clearer at 4 weeks than at one week of the experiment.
