  • This study was aimed to compare nutrition knowledge, dietary attitude and habit of elementary school children with and without education. Eighty-four subjects with unbalanced eating behavior were selected and assigned to either control or education group. The subjects in education group participated in a nutrition education program once a week for 8 weeks. The contents of nutrition education were on food tower, balanced nutrition, nutrient function, food group, importance of breakfast, and nutrition label, etc and the program was performed by a school dietitian. The effects of education was assessed by self-administered questionnaire prior to and after nutritional education. Nutrition knowledge except on snack, dietary self-efficacy except on low fat/ low calorie, attitude except on functional food and favorite, and general dietary habits of children in education group were significantly improved while those in control group showed no changes. Also, factors for unbalanced eating was improved by nutrition education indicating the need for correction on unbalanced eating was diminished. However, children's adherence to snack, instant and fast food remained to be corrected. The dietary habit of balanced eating was improved by education reducing the percentage of unbalanced eating on grain and meat.fish.milk groups. The nutrition education appears to be effective to provide nutrition knowledge thereby to improve dietary attitude, dietary self-efficacy, and partly to reduce children's unbalanced eating factor.

  • To assess trans fatty acids (tFAs) intake of middle school students in Busan, behavior of having meals and 3 day's food record were surveyed in 800 subjects. 35.3% of subjects responded to twice a day in frequency of snack intake. Preferred snack items were ice cream (68.6%) and milk (57.0%). Subjects of dining out preferred jajangmyon (54.6%), seasoned chicken (50.5%), fried chicken (35-3%) in order when dined out. Mean daily tFAs intake of subjects was 1.68$\pm$0.04 g. Mean daily intake level of girls was 1.89$\pm$0.06 g which was significantly higher than that of boys, 1.40 $\pm$ 0.05 g (p<0.001). Naturally derived tFAs intake was 1.04$\pm$0.03 g which corresponded to 62.1% of total tFAs intake per day and industrially derived tFAs intake was 0.64 $\pm$ 0.02 g, 37.9% of total tFAs intake per day. Calorie percentage of tFAs was 0.8% and fat percentage of tFAs was 3.16%. The level of tFAs intake showed a significant difference with monthly allowance (p<0.05) and frequency of snack intake (p<0.001) in girls, which was not the case in boys. The main sources of tFAs were milk and dairy products (34.3%), bakeries (18.3%), and fish and meat products (16.2%), in order. From above results, we can conclude that tFAs intake of middle school student is not as much as that of Western teenagers. However, exact estimation of tFAs intake requires database of tFAs in broad range of processed foods commonly consumed in Korea.

  • To determine the influence of vegetarian diet on serum lipoprotein, cholesterol and protein levels, 45 young Buddhist nuns (age: $20{\sim}34$ years) and 29 female students(age: $20{\sim}22$ years) were examined. Daily caloric intakes were 1,945 Kcal for the Buddhist nuns and 1,815 Kcal for the students. The ratio of% calorie of carbohydrate: protein: fat from total calories in the Buddhist nuns was 84:11:5 and that in the students was 70:15:15. The Buddhist nuns had significantly higher carbohydrate intake but markedly lower lipid intakes than the students. Anthropometric measurement showed that the Buddhist nuns had significantly higher values of body weight, skin-fold thickness, body surface area and obesity index than the students. Both systolic and diastolic pressures of the Buddhist nuns and students were similar. Serum levels of total lipid, cholesterol and proteins in the Buddhist nuns were not different from those of the students. However, when comparing the levels of high density lipoprotein (HDL), very low density lipoprotein (VLDL) and low density lipoprotein (LDL) fractions, the Buddhist nuns had lower level of HDL but significantly higher LDL levels than the students. Furthermore, the Buddhist nuns had significantly lower levels of serum HDL-cholesterol but significantly higher LDL-cholesterol levels. There were significant correlations between LDL and LDL cholesterol (r=0.40), VLDL and VLDL-cholesterol(r=0.85), HDL and HDL-cholesterol(r=0.45), total serum lipid and total cholesterol (r=0.66) and total serum cholesterol and LDL(r=0.79). On the other hand, values of both serum total protein, and fractions of serum proteins were similar in the Buddhist nuns and students(ratio of albumin: ${\alpha}_{1}-:\;{\alpha}_{2}-:\;{\beta}-:\;{\gamma}-$globulins=55:3:10:13:19). Hematocrit and hemogloblin levels were similar in the Buddhist nuns and students. Above results suggest that vegetarian diets of the Buddhist nuns produced alterations in the metabolism of the lipoproteins and cholesterol.

  • Meal menus were developed and applied for rural elderly of Gangwon and Chungnam areas at agricultural off-season. Amounts of the major nutrients of carbohydrate, protein, lipid, and calorie considered in the menu based on the dietary reference intakes(DRI) of the elderly aged over 65 years were 97.5g, 22.5g, 13.3g, and 600kcal, respectively. In Chungnam, softness and overall acceptance of rice in menu 4, consisted of cereals and rice, kimchi stew with tuna, pan-fried bulgogi mushroom, seasoned dropwort carrot, kimchi, and banana, scored the highest values of 8.5 out of 9.0point hedonic scale (p<0.05). In Gangwon, soup and side dish of menu 3 (rice, frozen pollack pot stew, meatball fried in egg, seasoned sea lettuce, and banana) scored significantly the highest of all (p<0.05). Overall acceptance of all the menus were high over 7.8 without significance in Chungnam. Overall acceptance of the menu 3 scored significantly the highest with value of 8.5 and menu 4 (rice, spicy chicken soup, seasoned bean sprouts, broiled brown seaweed trunk, kimchi, tomato) had significantly the lowest value with value of 7.8 in Gangwon(p<0.05). The total leftover volume of menu 4 was significantly the highest with score of 56g and the menu 4 showed the highest unit cost of 2,900won in Chungnam. However, the total leftover volume of all menus did not show significance ranging from 9g to 19g in Gangwon.

  • The present study estimates intake levels of dietary fiber (DF) in Korean adults aged 20 and over, using a newly established dietary fiber database for 3,149 food items, as well as 24-hour recall method data from the 2001 Korean National Health and Nutrition Survey. Dietary fiber intake and food groups are analyzed by gender, age, and region. The average dietary fiber intake, per capita of Korea was estimated to be 12.24g/1,000kcal or 23.58g/day. Calorie-based dietary fiber intake for 20-49 year-old-Korean males, 20-29 year-old females, and the adults who resided in metropolitan areas was under the Adequate Intake for DF, 12 g/1,000 kcal. Further, the dietary fiber intake after adjusting energy intake in people over 75 year-old was estimated to be 75% of AI. Vegetables, cereals and fruits were three major sources of DF for Korean, making up approximately 75% of DF. Regarding the subjects of this study, major sources of dietary fiber were Kimchi and well-polished rice, which supplied 13.98% and 9.16% of total dietary fiber intake, respectively. The result of this study could contribute to the establishment of DRIs for dietary fiber, after adjusting energy intake for Korean aged 75 years and over. The beneficial health effects of DF and the necessity of nutritional education in this area should be continuously emphasized concerning 20-29 year-old people and metropolitan adults.

  • This study was designed to investigate the effects of various sources of dietary fats on the blood and liver cholesterol(CHOL) levels in young Single Comb White Leghorn male chicks, In experiment 1, corn oil, palm gil, tallow and fish oil were added individually at a level of 4% to semipurified type diets composed of isolated soyprotein and glucose as major components. The diets were fed ad libitum for a period of 15 days. In experiment 2, various fats such as corn oil, soybean oil, repeseed oil, palm oil, tallow, fish oil and hydrogenated fish oil(HFO) were added individually at a level of 11.4% to practical type diets primarily based on corn and soybean meal. Control diet contained 3% of corn oil. All these diets were formulated to contain equivalent amount of nutrients such as protein, vitamins and minerals on a basis of unit kcal of metabolizable energy. The third Experiment was to compare the effects of different levels of calorie/protein(C/P ratio) of diets on the performances and various biological parameters in the chicks. Control diet was the same as in experiment 2. Another diet was added with 11.14% corn oil(C/P ratio=146) and the other diet with 10% corn oil(C/P ratio=164), The diets in experiment 2 and 3 were fed ad libitum for 26 days. In the first experiment, the chicks fed the diet containing vegetable oils tended to grow faster and show better feed efficiency without significance than those fed diets added with animal fats. However, this tendency was not observed in the experiment 2. Birds consumed the diets added with fish oil appeared to have heavier liver weight and higher liver CHOL than the others(p〈0.05), No significant differences in the levels of blood CHOL and triacylglycerol(TG) were observed among the chicks of various dietary groups(Exp. 1). Weights of liver or heart were significantly heavier in the chicks consumed the diets added with HFO or fish oil, respectively(Exp. 2). However, chicks ingested diet containing fish oil appeared to have significantly lower plasma CHOL. No significant differences were observed in the levels of liver CHOL and plasma TG among the dietary groups. Birds consumed the diet with a wider C/P ratio resulted in higher liver TG levels in experiment 3(p〈0.05). Although no statistical differences were observed among the various dietary groups, chicks fed the diet with a wider C/P ratio tended to show higher levels of plasma CHOL, TG, liver CHOL and total liver lipids compared to those of the control group.

  • The effect of liming on the potassium equilibrium activity ratio ($AR^k_e$) of Chinese cabbage cultivated soil and on the potassium uptake by the plant summarize as follows: 1. $AR^k_e$ is raised by the application of 1.6 ton of $Ca(OH)_2$ per hectare that required amount to adjust pH 6 for the soil. Generally, it could be confirmed that both liming and potassium placement to the soil show the combined effects to raise $AR^k_e$. 2. The exchangeable potassium and the electrical conductivity increase by liming. The mean value of the exchangeable potassium is 0.71 m. equ. per 100g of limed soils while the control give 0.64 m. equ. per 100g. For the electrical conductivity, limed soil show $766{\mu}mho$ and $750{\mu}mho$ is for the control. 3. The reason $AR^k_e$ value increase by liming could be considered that concentrations of $K^+$ and $Ca^{{+}{+}}+Mg^{{+}{+}}$ in the equilibrium solution are increased owing to release both K and $Ca^+$ Mg into the liquid from solid phase in the potassium equilibrium system of the soil. 4. For considering that the energies of exchange of calcium by potassium in the limed soils at different potassium treatment, that is without K, 200 kg $K_2O/ha$ and 350 kg $K_2O/ha$, give -3887 and -3778 and -3737 calories per chemical equivalent respectively. On the other hand in case of the controls which received the same amounts of potassium as mentioned above, energy values are -3983, -4392 and -4228 calories respectively. 5. The absorbed amount of potassium and weights of dry matters of the plant which grown in the limed soils show little higher values than the controls.

  • A layer feeding trial was conducted for 10 weeks to investigate the effects of the addition of corn distillers dried grains with solubles (DDGS) to layer diets on the laying performance, egg qualities, and yolk fatty acid composition. Nine hundred Hyline Brown layers, 24 weeks of age,were randomly allotted to 20 replicate laying cages, 45 birds per replicate. There were four diet treatments (0, 10, 15, and 20% DDGS), and five replicates per treatment. All experimental diets were prepared to contain iso-protein (17%) and iso-calorie (TMEn 2,780 kcal/kg). The use of DDGS up to 20% level in layer diets did not exert any influence on feed intake, laying rate, total egg mass, mean egg weight, and feed conversion ratio. DDGS did not exert any influence in weight of egg, breaking strength, and color of eggshell. The albumen height and Haugh unit was not influenced by DDGS addition. The yolk color was significantly increased by DDGS supplementation. As the DDGS level increased, the oleic acid content decreased, and the linoleic acid increased (P<0.05). The degree of saturation of yolk fatty acids was not affected by dietary DDGS. The inclusion of DDGS up to 20% in layer diets resulted in the decrease of feed cost per kg without any effect in the laying performance. In conclusion, the use of DDGS up to 20% level in layer diets could replace corn and soybean meal without any harmful effect on the laying performances.

  • The purpose of this study was to investigate the effects of medical nutrition therapy(MNT) on plasma lipid levels of hyperlipidemic patients with apo E3 genotype according to Sasang Constitutions. From March to July, 2001, the 33 hyperlipidemic patients admitted to K University Medical Center were studied. The study subjects were classified according to their Sasang constitutions by QSCC II questionnaire which have been used at K University Oriental Medical Center. The anthropometric assessments, blood analysis, and apo E genetic typing were carried out. Nutrient intake was determined by food record method of food taken during two weekdays and one weekend. The MNT including the instruction for hypolipidemic and hypocholesterolemic diet (step l diet) was performed for 12 weeks. The results are as follow; (1) The mean age of hyperlipidemic patients was $49.91{\pm}8.48$ years. (2) The distributions of Sasang Constitution were 60.6% of Tae-eum, 21.2% of So-yang, and 18.2% of So-eum. The distributions of apo E genotype were 6.5% of apo E2/3, 78.8% of apo E 3/3, and 15.2% of apo E 3/4. (3) The nutrient consumption of the apo E3 subjects before the MNT showed lower calorie, iron, calcium, and vitamin B2 intakes than the RDAs for each nutrients with no significant differences among the constitutions. After 12-week of MNT, only the fat consumption was decreased in the Tae-eum group. The MNT did not change the pattern of food intake. (4) The plasma level of triglyceride, total cholesterol, and LDL-C were not changed after MNT in the three constitutional groups. The level of HDL-C was significantly increased significantly in Tae-eum and So-yang group and the level of homocystein was lowered in Tae-eum group after MNT. It could be concluded that the 12-weeks MNT with hypolipidemic and hypocholesterolemic diet did not change the level of total cholesterol, triglyceride, and LDL-C effectively regardless of Sasang constitutions even though the subjects' dietary intake was improved by MNT.

  • The sensory acceptability, texture profile analysis and nutritional evaluation were peformed in Korean traditional mungbean pancake (MPC) and modified MPC containing squid meat and soybean to standardize the recipes for healthy fast food market potentiality. Optimal ingredient formulations were revealed as mung-bean 55$\%$, pork 13$\%$ and vegetables 32$ \%$ for traditional MPC, and pork 3$\%$, squid 42$\%$ and soybean 55$\%$ for modified MPC using response surface methodology. Flavor and hardness correlated highly with overall accept-ability rather than appearance and color of traditional MPC. Higher squid levels raised adhesiveness, springi-ness and resiliences of modified MPC, but soybean decreased these textural attributes. Protein, lipid and total calorie of modified MPC were lower than those of traditional MPC. Computed protein efficiency ratio (C-PER) and degree of gelatinization of modified MPC were superior than traditional MPC.
