This study was designed to observe the effects of the fish oil and some seed oils on the improvement of the lipid composition in rats. In order to induce the triglyceridemia in the rats of the Sprague-Dawley, 12% coconut oil and 3％ each of olive oil, lard, fish oil, perilla oil, corn oil, red pepper seed oil and evening primrose oil were administered to the rats for tweets. Total cholesterol concentrations of serum were lower in the fish oil, perilla oil and corn oil groups and by for higher in the red pepper seed oil and evening primrose oil groups than in the olive oil group(control group). HDL-cholesterol concentrations were a little higher in the red pepper oil and evening primrose oil groups. In the ratio of HDL-cholesterol concentrations to total cholesterol concentrations, all groups were higher percentage than the control group. Cholesteryl ester concentrations of serum were high in n-6 PUFA rich red pepper seed oil and evening primrose oil group. In the ratio of cholesteryl ester concentrations to total cholesterol, all groups(70.0~74.4%)were higher than the control group(62％). Phospholipid concentrations of serum were low in the fish oil and perilla oil groups and triglyceride concentrations were remarkably lower in the fish oil and evening primrose oil groups than in the control group. LCAT activities of serum were higher in the lard group than in the control group, but lower in the other groups.

Fish-frames, which are left after obtaining fillets or muscle during fish processing, consists of useful food components, such as muscle, collagen, calcium, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). This study was carried out to prepare snack using conger eel frame (SF) for human consumption and also to elucidate food component characterization of the snack. The results of volatile basic nitrogen suggested that conger eel frame was a suitable material for preparing snack. Based on the results of sensory evaluation and costs, starch syrup was an optimal sweetener for preparing snack using conger eel frame. The starch syrup-treated SF appeared safe because the moisture content and peroxide value were below the safety limits described in the guideline of Korea Food and Drug Administration (KFDA). Starch syrup-treated SF was similar in the pattern of fatty acid composition to soybean oil, whereas EPA and DHA were detected in SF. The total content of amino acid in starch syrup-treated SF was 23.9% based on 100 g of raw material. The maj or amino acids were aspartic acid, glutamic acid, glycine and alanine. The total contents of calcium and phosphorus in starch syrup-treated SF were 4.9% and 2.8%, respectively. The Ca/P of starch syrup-treated SF was 1.9, which is a good ratio for absorption of calcium. The SF made with starch syrup was superior in EPA and DHA compositions, total amino acid, calcium and phosphorus contents to commercial snack using eel frame.

In this study, the fried fish paste was prepared from Alaska pollack meat paste added with propolis. The quality characteristics were analyzed by peroxide value, gel strength, color, viable cell count and sensory evaluation. The fried fish paste product had lower peroxide value and viable cell count after frying compared to the one without propolis. The antioxidant and antispoiling ability of propolis in fried fish paste increased with content of propolis. Gel strength increased with increasing addition of propolis. L-value decreased but a-value and b-value increased with the addition of propolis. In sensory evaluation, 0.17% propolis had the best score in overall acceptability. These results indicate that the fish paste could be prepared by adding the propolis for high quality and functionality. Consequently, propolis can be applied as a food preservative or additive.

In order to identify hard distinct 12 fish species(shiba shrimp Metapenaeus joyneri, fleshy shrimp Penaeus orientalis, ridgetail prawn Palaemon carinicauda, yellow croaker Pseudosciaena manchurica, croaker Niber albiflora, Colichthyes fragilis, brown sole Limanda herzensteini, frog flounder Pleuronichthys cornutrs, Areliscus rhomaleus, stone flounder Kareius bicoloratus, harvest fish Pampus argenteus, flag fish Goniistius zonatus) by seeing with naked eye in Kunsan coastal area, sarcoplasmic protein in the supernatant was used for isoelectric focusing. For getting supernatant, fish muscle tissue was blended with two times deionized water and centrifuged (at $4^{\circ}C$, 12,000rpm for 15min). Isoelectric focusing of sarcoploasmic protein carried out on a LKB Multiphor II using polyacrylamide gel plate (2mm thickness, pH $3.5~10^{\circ}C$, pH 5~8 gradient, at $10^{\circ}C$ for 1.5, 3 hours). In case of uncertain protein pattern, pH gradient was modified to narrow pH gradiet, and excuted 2-D electrophoresis using conventional polyacrylamide gel electrophoresis. Most of fishes except yellow croaker and Collichthyes fragilis were distingushed by isoelectric focusing. The protein maps of 2-D electrophoresis for analyzing two protein bands at aimilar positions(pH 5, 6) between the two fish species showed the diffeences of the estimated molecular weights, 11,700(pH5.0) and 87,000(pH6.0)

One hundred twenty healthy college students and housewives from urban middle income household were investigated in terms of food consumption patterns, nutrient intake and dietary fiber intake. Total food intake was slightly lower in college students(1059.9g/d) than in housewives(1160.g/d) . However, the ration of animal food to total food was considerably higher in college students(23.7%) than in housewives(16.8%). College students tended to consume more dairly products, meat & products, and cereals & grain products but less vegetables , fruits, fish and shellfish than housewives. Although nutrient intake was not much different (except for total calories, fats, and ascorbic acid), dietary fiber intake was slightly and significantly lower in college students(14.9g/d, 8.3g/1000kcal) than in housewives(16.9g/d, 103g/1000kcal) . That is partially due to college students irregular food habits and the change in their meal patterns from traditional to western diets. There was a significantly positive correlation between dietary fiber intake and thiamin, riboflavin, niacin and crude fiber intake.

Background: This study aimed to provide an overview of lifestyle changes after breast cancer diagnosis and to examine the relationship between dietary and physical activity changes with weight changes in breast cancer patients. Women with breast carcinomas (n=368) were recruited from eight hospitals and four breast cancer support groups in peninsular Malaysia. Dietary and physical activity changes were measured from a year preceding breast cancer diagnosis to study entry. Mean duration since diagnosis was $4.86{\pm}3.46$ years. Dietary changes showed that majority of the respondents had decreased their intake of high fat foods (18.8-65.5%), added fat foods (28.3-48.9%), low fat foods (46.8-80.7%), red meat (39.7%), pork and poultry (20.1-39.7%) and high sugar foods (42.1-60.9%) but increased their intake of fish (42.7%), fruits and vegetables (62.8%) and whole grains (28.5%). Intake of other food groups remained unchanged. Only a small percentage of the women (22.6%) had increased their physical activity since diagnosis where most of them (16.0%) had increased recreational activities. Age at diagnosis (${\beta}$= -0.20, p= 0.001), and change in whole grain (${\beta}$= -0.15, p= 0.003) and fish intakes (${\beta}$= 0.13, p= 0.013) were associated with weight changes after breast cancer diagnosis. In summary, the majority of the women with breast cancer had changed their diets to a healthier one. However, many did not increase their physical activity levels which could improve their health and lower risk of breast cancer recurrence.

BACKGROUND/OBJECTS: When the functions involved in the ingestion of food occurs failure, not only loss of enjoyment of eating, it will be faced with protein-energy malnutrition. Dysmasesis and difficulty of swallowing occurs in various diseases, but it may be a major cause of aging, and elderly people with authoring and dysmasesis and difficulty of swallowing in the aging society is expected to increase rapidly. SUBJECTS/METHODS: In this study, we carried out a survey targeting nutritionists who work in elderly care facilities, and examined characteristics of offering of foods for elderly and the degree of demand of development of easily chewable and swallowable foods for the elderly who can crush foods and take that by their own tongues, and sometimes have difficulty in drinking water and tea. RESULTS: In elderly care facilities, it was found to provide a finely chopped food or ground food that was ground with water in a blender for elderly with dysmasesis. Elderly satisfaction of provided foods is appeared overall low. Results of investigating the applicability of foods for elderly and the reflection will of menus, were showed the highest response rate in a gelification method in molecular gastronomic science technics, and results of investigating the frequent food of the elderly; representative menu of beef, pork, white fish, anchovies and spinach, were showed Korean barbecue beef, hot pepper paste stir fried pork, pan fried white fish, stir fried anchovy, seasoned spinach were the highest offer frequency. CONCLUSIONS: This study will provide the fundamentals of the development of easily chewable and swallowable foods, gelification, for the elderly. The study will also illustrate that, in the elderly, food undergone gelification will reduce the risk of swallowing down to the wrong pipe and improve overall food preference.

The objectives of this study were to examine the association between dietary factors and underweight and overweight adult Vietnamese living in the rural areas of Vietnam. A cross-sectional study of 497 Vietnamese aged 19 to 60 years (204 males, 293 females) was conducted in rural areas of Haiphong, Vietnam. The subjects were classified as underweight, normal weight, and overweight based on BMI. General characteristics, anthropometric parameters, blood profiles, and eating habits were obtained and dietary intake was assessed using 24-hour recalls for 2 consecutive days. A high prevalence of both underweight (BMI < 18.5 kg/$m^2$) and overweight (BMI ${\geq}$ 23 kg/$m^2$) individuals was observed (14.2% and 21.6% for males and 18.9% and 20.6% for females, respectively). For both genders, the overweight group were older than the under- and normal weight groups (P = 0.0118 for males and P = 0.0002 for females). In female subjects, the overweight group consumed significantly less cereals (P=0.0033), energy (P = 0.0046), protein (P = 0.0222), and carbohydrate (P = 0.0017) and more fruits (P = 0.0026) than the underweight group; however, no such differences existed in males. The overweight subjects overate more frequently (P = 0.0295) and consumed fish (P=0.0096) and fruits (P=0.0083) more often. The prevalence of both underweight and overweight individuals pose serious public health problems in the rural areas of Vietnamese and the overweight group was related to overeating and high fish and fruit consumption. These findings may provide basic data for policymakers and dieticians in order to develop future nutrition and health programs for rural populations in Vietnam.

To evalulate the antioxidant effect of flavonoid(+)-catechin on n-3 polyunsaturated fatty acids in vivo, rats were fed with diets containing $5\%$ corn oil(CO), $5\%$ corn oil and $15\%$ purified fresh fish oil(FO) or peroxidized fish oil(PFO) for 10 days. To accerelate lipid peroxidation, all of them were injected with 60mg phenobarbital(a day per kg body weight), and treated with phorone(diisopropylidene acetone) before the rats were killed. Contents of triglyceride, phospholipid, cholesterol and lipid peroxide and the activities of GOT, GPT in serum and total lipid and cholesterol content in liver of PFO group rats were significantly higher than those of the FO one. Contrary to our expectations, the activities of superoxide dismutase (SOD), catalase and glutathione peroxidase(GSH-Px) in liver of the FO group were ]ewer than those of the PFO group. These results might be explained as the results of homeostasis. Even though the hepatic glutathione were depleted, catechin and a-tocopherol inhibited production of lipid peroxide effectively. These results suggested that catechin be considered an antioxidative and hepatoprotective agent.

The purpose of this study was to evaluate the satisfaction with school meal service and the food preference in elementary school students who are in their growth period. A total of 484 students (242 boys) participated and completed a questionnaire survey. The results indicated that the merit of school meals was the highest in 'balanced diet'. 'Food hygiene' and 'delicious food' were the most important factors in school meals. Most of the students wanted 'balance between eastern and western foods' and 'new dishes' for the menu of school meals. For the distribution of meals, 'various kinds of side dishes' and 'warmth of dishes' were mainly required. The main problems of the current environment of school meals were 'long waiting time' and 'noise of the cafeteria'. In satisfaction with the school meal service, the highest satisfactory factor was 'staffs' cleanliness', following 'arrangement of furniture in cafeteria' and 'nutrition information-providing'; whereas, the lowest factor was 'staffs' kindness'. In the preference of foods, students preferred 'white rice'; whereas they did not like 'bean rice'; and 'fried rice' was preferred. In side dishes with meat and fish, most of the meats including 'Tangsuyuk' and 'Bulgogi' were preferred. For fish, 'fried hairtail' was preferred; whereas, 'fried Spanish mackerel' was not. In case of kimchi, 'Chinese cabbage kimchi' and 'cubed radish kimchi' were especially preferred. Considering these results, intensive improvement is required to increase school meal satisfaction by understanding the students' needs. An effort to allow the students' preferences to be reflected in the menu is also needed.
