The purpose of this study was to investigate the regional 야fferences in dietary supplement use and related factors among college students participating in nutritional education programs via the internet. The subjects in this study were 797 college students (male: 518, female: 279). A cross-sectional survey was conducted using a self-administered questionnaire about dietary supplement use, demographic characteristics, health-related lifestyles, nutrient intake, and data were collected via the internet and by mail. Dietary supplements were taken by 82.2% of subjects (males: 76.3%, females: 85.3%). There was a significant regional difference in supplement use (p<0.01). The supplements, used most frequent by male students in the Seoul and Incheon areas were lactic acid beverages and gagogi, in that order. Male students in the Kyunggi area used gagogi and lactic acid beverages in that order. Lactic acid beverages and Chinese medicine were used most frequently by male students in the Chungcheong area. Male students in the Kyungsang area used lactic acid beverages and water-soluble vitamins, in that order. Male students in Seoul and Kyungsang areas showed significantly higher percentage of keep on taking supplements compared to other areas (p<0.05). Both male and female students in the Seoul area had more frequent medical examinations, in comparison to students in other areas (p<0.05). Male students in the Kyungsang and Seoul areas took significantly more calcium (p<0.05) and iron (p<0.05), in comparison to students in other areas. Female students id the Kyunsang area took significantly more Vitamin A, phosphorous and iron (p<0.05), while those in the Seoul area took significantly more Vitamin C (p <0.01) and calcium (p<0.05) . Male students in the Chungcheong area took significantly less seaweed, in comparison to students in other areas (p<0.05) . Male students in the Seoul area had the highest amount of animal fat and oil, while those in the Incheon area ate the lowest amount of animal oil and fat (p<0.05). Female students in the Kyunggi area ate the highest amount of fruit, while those in the Incheon area ate the lowest amount of fruit (p< 0.05) , Female students in the Incheon area ate the highest amount of seaweed, while those in the Kyunggi area ate the lowest amount of seaweed (p<0.01). Therefore, it can be concluded that it is necessary to develop dietary supplements to optimize the nutritional status of college students in different areas of Korea.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

Calcium intake has been insufficient in all age groups in previous Korean national surveys. This study was conducted to investigate calcium intake in Korean and American populations at different ages. We analyzed two national survey data: the 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES) and the 2007~2008 National Health and Nutrition Examination Survey (NHANES). Statistically, survey procedures were applied using the weight, cluster, and strata variables. The mean calcium intake of Koreans at ages of 1~2 y, 3~5 y, 6~11 y, 12~18 y, 19~64 y, and 65+y was lower than American populations at those ages. The sufficient proportions based on Korean Estimated Average Requirement (EAR) of 1~2 y, 3~5 y, 6~11 y, 12~18 y, 19~64 y, and 65+y in Koreans were 45.5%, 33.1%, 24.3%, 16.6%, 32.7%, and 19.0%. While the sufficient rates based on American EAR of 1~3 y, 4~8 y, 9~13 y, 14~18 y, 19~30 y, 31~50 y, 51~70 y, and 71+y in US population were 88.5%, 54.4%, 35.2%, 35.8%, 55.3%, 55.2%, 40.6%, and 24.5%. Overall, the major foods contributing to calcium intakes in Koreans were milk, baechukimchi, and anchovies, whereas, milk products, pasta, or bread were major contributions to calcium in American populations. The calcium supplement intakes in the American population were 5.5 mg (1~2 y), 15.5 mg (3~5 y), 13.9 mg (6~11 y), 35.7 mg (12~18 y), 150.3 mg (19~64 y) and 334.4 mg (${\geq}65$ y). These results suggest that Korean adolescents and older adults are the most insufficient in dietary calcium intakes among Koreans. In order to accurately estimate calcium intakes in Korean populations, calcium supplements and calcium-fortified foods should be considered.

The aim of this study was to investigate the effects of chicory fructan fiber supplementation on bone mineral density, apparent absorption of minerals and serum parameters related to bone turnover in postmenopausal women. Twenty-six healthy Korean postmenopausal women participated in the study. 1be participants were randomly divided into two groups in a double-blind parallel design and took one of the supplements for 3 months; either a placebo of 8g maltodextrins/sucrose mixture (control group) or 8g chicory fructan fiber (fructan group). During the 3-month experimental period no differences were found in bone mineral density (BMD) between the two groups. Apparent calcium absorption significantly increased by 42% in the fructan group, while that of the control group decreased by 29% as compared to the values at baseline. Urinary calcium excretion was not significantly different between the group;;. After 3 months, the level of serum alkaline phosphatase (ALP) was significantly lower in the fructan group than in the control group and deoxypyridinolin showed a trend toward a slight reduction. In conclusion, intake of chicory fructan fiber with a regular increases apparent calcium absorption in postmenopausal women.

These studies were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance of broiler chicks. Diets were based corn, soybean meal and contained 3,100kcal/kg ME, 21% CP for the rest two weeks. Three levels of dietary lincomycin(LM; 0,2.2, 4.4mg/kg) and food waste(FW; 0, 7.5, 15%) were respectively inclusion in both experiments. In experiment 1, weight gain of birds fed 4.4mg/kg LM was significantly higher than no LM treatments(P<0.05). It tended to increase in 7.5% food waste treatment compared to that of control, but was not significantly different. FCR of chicks fed 2.2mg/kg LM supplement was significantly improved compared to that of other treatments Chicks fed food waste showed inferior FCR to control as dietary FW level increased(P<0.05). There was no significance in blood components among treatments. In experiment 2, weight gain of chicks fed 15% FW exhibited higher weight gain than that of other treatments. As FW supplement increased, the feed intake increased significantly(P<0.05) There was no significance in blood components except serum calcium. The results of these experiments indicated that hicks fed 4.4mg/kg LM supplements maximized growth rate of all treatments, and improved FCR in 2.2mg/kg LM.

The issue of health and nutritional wellbeing becomes one of the utmost concerns for the welfare of the elderly in a society of increased aging populations. This study was conducted to assess nutritional state and to identify possible dietary factors that might influence health and nutritional state of the free living elderly women. Two hundred sixty two elderly women, aged 60-90 who are actively participating in a continuing education program for the elderly in Seoul area, were interviewed using a dietary habit questionnaire and a 24-hour recall. Anthropometric measurements such as heights, weights, body mass index, and tricep skinfolds and dental status were significantly different between the two age groups, <75 and ${\geq}$ 75 years of age. Sixty eight percent of the subjects were using nutritional supplements regularly, in the descending order of vitamin-mineral supplements(40%), botanicals(27.6%), tonic drinks(16%), and health foods(13.2%). For hot beverages, our study subjects drank coffee (33.6%) and green tea (17.9%) frequently, followed by doongulae, job's tears, citron and kyulmyung tea. With regard to micronutrients, vitamin C intake was found to be lower in the group aged over 75 compared to that below 75 (p<0.05). Calcium intake was significantly higher among the elderly with good dental status followed by the groups with gingivitis, denture, and missed teeth with poor chewing abilities (p<0.05). The amount of personal spending money was found to be a significant contributing factor (p<0.05) to the energy and nutrient intake in an individual. The results of the present study can be applied to the identification of the possible factors that might intervene the aging process, to the planning of the nutrition education program, and to the development of health food products for the promotion of health and nutrition of the elderly women.
