Anti-obesity effect of biocellulose and diet formulation containing it was evaluated using obese rats. Thirty male Sprague-Dawlely (SD) rats were randomly assigned to high-fat diet group (CON), high-fat diet group containing 5% biocellulose (BIO), and high-fat diet group containing 5% dietary formulation (DF). After 10 weeks, body weight gains of BIO and DF groups were reduced by 15.1 and 6%, respectively, as compared with CON group. Epididymus, parirenal, and visceral fat pads of BIO and DF groups were lower than those of CON group. Weight of interscapular brown adipose tissues increased slightly in BIO group and significantly in DF group. Size of adipocyte in rats decreased in BIO and DF groups. Results indicate biocellulose-containing diet has anti-obesity effect by reducing body weight gain and white adipocytes depots in rats fed high-fat diet.

The purpose of this study was to examine the dietary behavior of children according to their preference for fast food. The study was carried out on 470, 6th grade students (boys : 236, girls : 234) in September, 2002. The results are summarized as follows : The mean body mass index was 18.72 kg/$m^2$ for boys and 17.76 kg/$m^2$ $^2$ for girls. The subjective health disorder symptoms for the group preferring fast food was not significantly different than that of the other groups. The group preferring fast food consumed an inadequate volume of food, and they had an irregular and unbalanced diet. Their intake of green vegetables, vegetables, protein foods, and seaweed was significantly lower than that of the other groups. The food habit score for the group preferring fast food was lower than that of the other groups, and they had irregular meal times and had unbalanced diets. The group preferring fast food had a preference for sweet tastes, whilst members of the other group preferred a savory taste. The first choice for fast food by the group preferring fast food was hamburgers, the reason being that it tasted good. Results show that children who have a preference for fast food need to correct their dietary behavior. As a result, proper nutritional education and intervention is required in order to improve the consuming habits of children and their preference for fast food.

This study was conducted to examine nutrient intake status and iron food sources by dietary iron density of high school girls in Seoul. The subjects of 226 girls were divided into High group (${\geq}$ 6 mg/1,000 kcal, N=115) and Low group (< 6 mg/1,000 kcal, N=111) by dietary iron density. The nutrient intake data obtained by 24-hour recall method were analyzed by Can Pro 3.0 software. Mean age of all subjects was 16.4 years old, heights and weights of High group and Low group were 164.5 cm, 53.4 kg and 161.7 cm, 51.7 kg, respectively. The body mass index (BMI) of High group and Low group was 20.5 kg/m$^2$ and 19.8 kg/m$^2$, respectively. Most nutrient intakes except energy and lipid intakes of High group were higher than those of Low group. High group showed significantly higher intakes of total iron, vegetable iron and animal iron than Low group. Ca and folate intakes of High group were under 75% of the recommended intake (RI) and Ca, iron, folate and vitamin C intakes of Low group were under 65% of RI. The percentage of subjects who consumed iron less than estimated average requirements (EAR) were 40.0% in High group and 77.5% in Low group. Total food intakes of High group showed higher than that of Low group. Total animal food intakes were significantly higher and total vegetable food intakes were significantly lower in Low group than those of High group. Iron intake from meats, fishes, shell fishes and seasonings were significantly higher in High group than Low group. Iron intake from milk and dairy products were significantly lower in High group than Low group. Major food sources of iron were rice, bean curd, pork, and egg in order among both groups.

This stusy was designed to develop nutrition education program for the primary school children served by the national school lunch program and to evaluate ist educational effects. Subjects consisted of 61 elementary school children(30 in the control group and 31 in the treatment group) in the 5th grade. Only the treatment group participated in a twelve-week nutrition education program. To evaluate the effects of the nutrition education program, the control and treatment groups were given a pretest and posttest for nutrition knowledge, food attitude, food habits, food preference and plate wastes before and after nutrition education. The results obtained are summerized as follows ; the nutrition knowledge test score (30.4) of the treatment group was significantly higher than that (17.4) of the control group after nutrition education . However, there was no significant difference between the two groups in food attitude test scores after nutrition education. We also did not find any difference induced by nutrition education or the food preferences of the treatment group. After nutrition education , the amount of plate waste of some menus were significantly decreased in the treatment group, but the amount of plate waste of the control group was not significantly changed. However, there was no significant difference in the post test scores above food habits between two groups. It was concluded that a twelve-week nutrition education program can improve nutrition knowledge and decrease plate waste but is not enough to change food attitude , food preference and food habits. It can besard that the two components of foodservice are nutritional foodservice and nutrition education. Foodservice management alone without nutrition education is hardly enough to improve the nutritional status of school children. The result of this study indicate that applying the nutrition education program to elementary school children who are served by the national lunch program can maximize the effects of the national school lunch program.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min/lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

The purpose of this study was to evaluate dietary intake according to the risk of coronary heart disease (less than 10% = low-risk group; 10~20% = middle-risk group) based on Framingham risk score (FRS), on 122 male adult subjects. The body weight and body mass index were not significantly different between the groups, while height of the low-risk group was shown to be significantly high compared to that of the middle-risk group. The daily energy intake was shown to be significantly high in the low-risk group with 1,910.88 kcal, compared to 1,606.63 kcal of the middle-risk group. As a result of analyzing nutrient intake per 1,000 kcal of energy, while the low-risk group had significantly high intake of animal protein, fat, and animal fat compared to the middle-risk group, the intake of plant protein, carbohydrate, and plant iron was found to be significantly low. The daily food intake was shown to be significantly high in the low-risk group (1,445.16 g), compared to the middle-risk group (1,075.12 g). The low-risk group was found to have significantly high intake of sugars, eggs, and beverages compared to the middle-risk group, while mushrooms intake was significantly high in the middle-risk group. Dietary variety score (DVS) was significantly high in the low-risk group with 26.42, compared to 22.66 of the middle-risk group. Dietary diversity score (DDS) was indicated to be significantly high in the low-risk group with 3.70, compared to 3.27 of the middle-risk group. The low-risk group was indicated to have significantly high score in DDS of dairy products and fruit group, compared to the middle-risk group. In the correlation between diversity index of food intake (DVS and DDS) and FRS, DDS was shown to have significantly negatively correlation with FRS after adjusting for confounding factors. To sum up these results, the adult males with low-risk of coronary heart disease had more various consumptions of fruits and milk, compared to the subjects with the middle-risk. The proportion of consuming major food groups such as cereals, meat group, milk, fruits, and vegetables more than a fixed quantity was indicated to be high. Accordingly, dietary habit for intake of various food seems to be necessary, to prevent coronary heart disease.

For the purpose of ascertaining the status of physical growth and food habit of obese children, a study was made of 1086 primary school children ranging between 2nd and 3ra grades living in Kwang-ju City in Korea. 66 subjects were selected from an anthropometrical point of view and they were classified into two groups, an obese group and a control group, according to their relative body weight. Food habits of each group were observed by means of questionnaires. In the statistical analysis of the data, percentage calculation and T-score test were used. The results of the study can be summarized as follows; 1) Viewed from relative body weight, 3.0% of the 1,086 subjects turned out to be obese, and the measure of skinfold showed 2.4%. 2) Physical growth of the obese growth is superior to that of the control group in all aspects. 3) The average score of food preference by means of Hedonic scaling method by the obese group is 3.90, while that of food preference by the control group is 3.76. The most favored food by the obese group is ice cream (4.91), while that of most favored food by the control group is banana (4.75). The statistically meaningful foods of the two groups are cucumber (0.02>p>0.01), orange (p<0.02), peach(0.05>p>0.02), watermelon (p <0.01) and ice cream (p<0.01). The score of food preference for protein foods by the obese group is 3.78 and that of food preference by the control group is 3.57(0.05>p>0.02). The excessive food intake per meal of the obese group is 45.4%, while that of the control group is 19.7% (0.05>p>0.02). Ratio of taking severely unbalanced food by the obese group is 15.1%, while that of the control group is 50.0% (p<0.01). 4) 30.3% of mothers of the obese group is fat, while 15.1% of mothers of the control group is fat (p<0.01). Concerning body weight at birth, 90.9% of the obese group and 63.6% of the control group are above-average weight. (p <0.01). From the results shown above, the obesity in children is almost due to food. It is hoped, therefore, that overeating be discouraged through the nutrition education.
