This study was conducted to evaluate the effects of adding gradually increasing concentrations of turmeric extract (0, 0.1, 0.2, and 0.4%) to smoked duck meat on its chromaticity, antibiosis, and antiseptic degree against food poisoning bacteria, number of bacteria, lipid rancidity, sensory evaluation, and preference. The brightness, red color intensity and yellow color intensity changed significantly when 0.2% turmeric extract was added and the sodium nitrate concentration was reduced. Additionally, no antibiosis or antiseptic activities against food poisoning bacteria were observed in any turmeric treated samples, whereas the number of bacteria was increased in control samples compared to turmeric treated samples after 10 days of preservation. The TBARS value decreased during storage when turmeric extract concentration increased, resulting in positive sensory evaluation of its color, succulence, taste and hardness. In the preference test, the surface and meat color increased as the concentration of turmeric extracts increased. Hardness was highest at 0.2%, whereas taste was highest between 0.2 and 0.4%. The overall preference test was highest for the 0.2% extract samples. Overall, the results indicated that addition of 0.2% turmeric to smoked duck meat will lead to better nutrition, function, and overall preference.

The principal objective of this study was to assess the effects of soy isoflavone supplementation on bone mineral density in 36 female college students with osteopenia for 12 weeks. The subjects were divided into three groups on the basis of bone mineral density. The experimental groups were provided supplements of either 80 mg of isoflavone (Iso-80) or 40 mg of isoflavone (Iso-40). To the placebo group, 40 mg of powdered glutinous rice was administered. It was determined that many subjects with osteopenia evidenced lower levels of activity as compared to the control group. Isoflavone supplementation was more effective in controlling total cholesterol and LDL-cholesterol than was observed in the placebo group. We noted no significant differences in serum osteocalcin concentration between Iso-40 and the placebo group, but significant differences in osteocalcin concentration were detected between Iso-80 and the placebo group. Bone quality indices (BQI) were correlated positively with mineral content, lean body mass, muscular mass, and blood components including albumin, Ca, Mg, ALPase, and osteocalcin. Both Iso-40 and Iso-80 supplementation for 12 weeks significantly increased protein and mineral content in the body. As lower intakes of Ca and folate were noted in the subjects, emphasis should be given to adequate intakes of these nutrients in the subjects. In conclusion, 12 week isoflavone supplementation in young females with osteopenia exerted positive effects on bone mineral density and bone turnover markers.

This study was undertaken to assess grade and gender differences in dietary behavior, food preference and perception about body image of students in 4, 5 and 6th grades in elementary school in Kwangju. Anthropometric data showed that mean height and weight were 137.98±6.79cm 32.69±6.09kg, in the 4th grade, 144.11±6.91cm, 36.88±7.60kg in the 5th grade and 151.52±7.47cm, 42.68±8.06kg in the 6th grade. Height and weight of male and female students of each grade were very similar to those of the Korean standard Growth data. Females in the 5th and 6th grades were taller than those in male students, which suggested the height growth spurt in females. Furthermore, both genders showed marked variability even in the same group. All the three different obesity indices(BMI, Rohrer and % of ideal body weight) showed higher value in males than in females consistently. Male respondents desired taller and heavier body shape while females perceived they were heavy and desired only taller and thinner body image. There were significant differences in satisfaction with height, weight and body image by grade(p〈0.05). 36.7% of subjects responded that they did not eat despite hunger. In higher grade they felt guilty after eating sweet things. Strikingly, it was noted a small number of students tried to take a diet pills or vomited on purpose. Data on food preference showed that female did not like sweet food and pork. While male students preferred red meat and chicken. Thus result indicated that there was a great difference in food preference by gender.

This study was undertaken to investigate meal pattern, nutrition knowledge and food preference of 438 rural middle school students living in ChunNam area. As far as nutrition knowledge is concerned, most subjects did not answer correctly on the items of basic five food groups, animal fat and vegetable oil, empty source of soft drink, nutrient requirement and water's role in energy metabolism. However they responded well on the item of iron deficiency and dietary source of Ca. Male students were significantly better in the answering the items of dietary source of energy and nutrient requirement than females, while female students were significantly better on the items of water's role in energy metabolism related to obesity. Generally the respondents did neither consume oil often nor consider consumption of salty food. Furthermore, only 38.6% of subjects drink milk daily in spite of understanding dietary source of Ca, which suggested that they should incorporate nutrition knowledge into dietary behavior. The preferred foods for most subjects were fruit, kimbab and ice cream. Contrastingly the food that they did not prefer was fermented vegetable probably due to strong flavor.

This study was undertaken to assess eating out behavior and factors in food choices of 369 college students in Kwangju. 47.1% of subjects ate out at least once a day and lunch was the most frequent meal for eating out. Eating out expenditure was significantly associated with student's allowances. Significant differences were observed in frequency, expenditure of eating out and related factors in food preference between male and female students. Taste was the most considered factor but nutrition was the least considered in food selection of respondents. Among male respondents, the most important nutritive factor was protein followed by calorie and vitamin. However, female counterpart regarded calorie as the most important nutritive factor affecting food selection. Tendency of increased vegetable and fruit consumption was noted in subjects over past a few years. It might be suggested that effective nutrition education for college students be implemented to improve and develop eating out behavior related to nutrition in food selection.

This study was undertaken to assess eating habits and food consumption pattern of 365 adolescent girls in Kwangju area. Subjects were divided into 3 groups based on relative body weight as obesity index. Anthropometric data showed that mean height and weight were 161.9±19.0cm and 53.3±7.2kg respectively which are similar to those in the Korean Standard Growth data. Mean BMI and relative body weight were 20.50 and 97.1%. Age of menarche in the subjects significantly influenced the obesity index. Food habit score in the underweight group was significantly lower than that in the normal group at α=0.2 level by multiple range test. Obesity was significantly associated with more frequent and irregular eating. It seems that students in the obese group were concerned on their body weight and tended to consume much vegetable. Obese group consumed more fruits, less butter and fruit juice compared to other groups. It might be suggested that more effective nutrition program might be developed and implemented to ensure good food habit of adolescent girls including obese as well as underweight group.

This study was undertaken to assess eating habits of 230 rural elementary school students living in ChunNam province. Anthropometric data showed that their mean height of girl students was significantly higher than that of boy students. Irregular eating pattern of girl students was noted. There was a significant difference in concerning on weight control between girls and boys. Girls especially view themselves as too obese even though their weight was in normal range and they were more concerned on weight control due to appearance. Nutrition education at school was an important factor ruling out peaky eating habits in participants. More effective nutrition education might be suggested to form a good eating habit which result in maintenance of ideal weight and promote health for rural elementary school students.

This study was undertaken to determine factors associated with infant feeding practices among highly educated Korean mothers living in Texas, USA and local populations. In both groups, infant's birth order, maternal age, prenatal education, husband's attitude, mother's attitude and infant's taking a bottle to bed were not associated with infant's feeding patterns significantly. However, there was a significant difference in initiating time for introduction of supplementary foods between Koreans and Americans. Thus Korean mothers introduced supplementary foods earlier than American counterparts. Furthermore the infant's feeding method among all participants affected the time for introducing supplementary foods significantly. Though attitude of Korean mothers toward breastfeeding was slightly more positive than that of American mothers, the prevalence of exclusive breastfeeding in Koreans was much lower than that in Americans. It might be suggested that effective nutrition education program for Korean subjects should be developed to practice breastfeeding from positive attitude and knowledge. It might be also suggested that participation of prenatal nutrition education involving fathers should be encouraged for promotion of rates of initiation and duration of exclusive breastfeeding of mothers.
