The purpose of this study was to provide basic data to improve college food service satisfaction with sanitary, environment and service by comparing 2 contract-managed and 2 self-operated college food services in Daejeon and Chungnam area. According to the results, sanitation and environment satisfaction degrees of contract-managed college food services were higher than those of self-operated food services. The satisfaction degrees with service were also higher in contract-managed food services than self-operated food services except the category of quick food delivery. In all categories comprising the food service satisfaction, the satisfaction degrees were lower in female students than in male students. There were more negative self-perceived clinical symptoms in female students than male students. The higher the negative self-perceived clinical symptoms scores were, the lower the satisfaction degrees with food service were, which suggests that the health state of students was one of the factors that influenced college food service satisfaction. There was no difference between contract-managed and self-operated food services in terms of satisfaction with overall food taste and overall satisfaction degree. The average satisfaction degree for the contract-managed food services in terms of price relative to food quality was lower than that for self-operated food services. According to stepwise multiple regression analysis, 'overall food taste', 'price relative to quality', 'kindness of employees', 'coping with proposed opinions' and 'quickness of food delivery' in decreasing order, were the most relatively important attributes for overall satisfaction. There should be further studies on important management factors to improve satisfaction with sanitary, environment and service by self-operated college food service.

College foodservice (FS) demands highly-developed operation technique which can provide adequate nutrients to their students, as well as to guide better eating habits and to meet students' various desires. The purpose of this study was to provide basic data to improve college FS satisfaction with food items by comparing 2 contract-managed and 2 self-operated college FS in Daejeon and Chungnam area. According to the results, 59.1% of students frequently (over 3 times per week) took meals at college cafeteria and the main reason for using college cafeteria was the low-price of meal, although the students' satisfaction degree with price of meal was lower in contract-managed FS than in self-operated FS. There were no differences in the food satisfaction degrees with overall appraisal of food items between 2 operating systems of college FS, but the satisfaction degrees with all food items were high in male as compared with female. The higher the negative self-perceived clinical symptoms scores, the lower the satisfaction with foods, which suggests that the health state of students was one of the factors that influenced college FS satisfaction. According to stepwise multiple regression analysis, 'taste of boiled rice', 'overall appraisal of boiled rice', 'overall appraisal of soup', and 'variety of side dish', in decreasing order, were the most relatively important attributes for overall customer satisfaction with food taste of college FS. Finally, there should be further studies on important management factors to improve college FS satisfaction according to 2 operating systems.

PURPOSE: The purpose of this study was to estimate dietary intake of vitamin D and the relationship between serum 25-hydroxyvitamin D (25OHD) concentration and bone mineral density (BMD) in Korean adults using the 2011 data from the Korea National Health and Nutrition Examination Survey. METHODS: Daily intake of vitamin D and ratio of subjects that consumed less vitamin D than adequate intake (AI) were estimated in 4,879 Korean adults. The relationship between daily intake of vitamin D and serum 25OHD and BMD were analyzed. RESULTS: Average daily intakes of vitamin D were 3.84 ± 0.23 µg/day for men and 2.22 ± 0.11 µg/day for women. Approximately 72~97% of men and 80~99% of women consumed less than the AI of vitamin D for Koreans. Serum 25OHD concentration increased with age, and the ratios of serum vitamin D deficiency (< 20 ng/mL) were 47.8~81.1% for men and 59.4~92.8% for women. Average intake of vitamin D was higher in subjects aged < 50 yr than in those ≥ 50 yr, but lower in serum 25OHD concentration. In subjects aged < 50 yr, serum 25OHD was higher in subjects that consumed 10 µg/day of vitamin D than in those that consumed less than 5 µg/day. In female subjects aged ≥ 50 yr, average intake of vitamin D was associated with higher bone mineral density. CONCLUSION: It was found that dietary intake of vitamin D could increase serum 25OHD concentration in young adults and bone mineral density in old women. Therefore, nutrition policies for enriched foods with vitamin D and nutrition education to consume more vitamin D-rich foods are needed to ameliorate vitamin D status of the Korean population. Adequate intake for Korean population aged < 50 yr might be adjusted upwardly up to 10 µg/day.

An analysis for a period of 15 months (from September 2000 to November 2001), of the nutrition counseling internet site, "Dietnet" served by the Korean Society of Community Nutrition, showed the following results. Nutrition counseling was conducted without charge by 50 professionals, including professors in the food and nutritional areas, medical doctors, and dietitians. Counselees consisted of mostly females under 30 years of age. Although two thirds of the users of this site asked questions anonymously, they were very sincere. They asked questions mostly related to their own concerns, but there were quite a few inquiries about their parents or grandparents. There were significant differences in the counseling contents depending on the ages of the counselees. Teenagers showed the highest interest in height growth and weight control, whereas people in their twenties were mostly interested in diseases, foods, and weight control. Those over the thirty made inquiries mostly about diseases. The most frequent questions were relevant to gastrointestinal, circulatory and hepatic diseases. As indicated above, counseling questions included of a variety of both comprehensive and specific questions. There were also quite a few questions related to decisions on the correct usage of specific foods. Therefore, we recommend that more professionals, such as food science majors, medical doctors who practice western and oriental medicine, and other professionals who specialize in psychological behaviors related to weight control and infant food habits be recruited to serve the site more effectively and intensively. In light of the further need for internet sites with nutrition counseling and delivery of nutritional information to the public, nutritionists capable of managing websites are also required.

This study was intended to assess the effects of low glycemic index (LGI) nutrition education on dietary management and glycemic control of patients with type 2 diabetes mellitus. The subjects were 48 sex-matched patients with type 2 diabetes mellitus, aged 66.5 +/- 6.2 years, visiting a public health center. They were divided into two groups: the control group (males 10, females 14) and the educated group (males 10, females 14). The educated group was provided with a LGI nutrition education program for 7 weeks. The control group was educated only one time for general diabetic education. Anthropometric indices, knowledge and perception of efficacy of low glycemic index carbohydrates, dietary glycemic index (DGI) and glycemic load (DGL), fasting blood glucose, and HbA1c were assessed. In the educated group body weight, body mass index and systolic blood pressure (from 138.0 +/- 18.9 mmHg to 130.6 +/- 15.0 mmHg) were significantly reduced after the nutrition education (p < 0.05). The scores of knowledge and perception of efficacy of low glycemic index carbohydrates increased significantly in the educated group. Dietary glycemic index and glycemic load of the educated group decreased significantly from 103.4 +/- 67.6 to 45.4 +/- 27.1 (p < 0.001), and from 173.3 +/- 135.9 to 66.8 +/- 50.4 (p < 0.001), respectively. Also fasting blood glucose and HbA1c levels of the educated group significantly decreased from 124.5 +/- 28.8 mg/dL to 96.7 +/- 21.6 mg/dL (p < 0.001) and from 7.1 +/- 1.3% to 6.4 +/- 1.2% (p < 0.05), respectively. The score of knowledge and perception of efficacy of low glycemic index significantly correlated with fasting blood glucose and HbA1c levels negatively. DGI, DGL and duration of diabetes significantly correlated with HbA1c level positively. From stepwise multiple linear regression analysis, DGI, DGL and the duration of diabetes were extracted as factors influencing HbA1c level of the subjects. The results of this study suggest that low glycemic index nutrition education programs is an effective intervention measure for the glycemic control in type 2 diabetic patients.

BACKGROUND/OBJECTIVES: Vitamin D plays an important role in skeletal growth and maintenance and in the prevention of various diseases. We investigated the relationship between vitamin D intake and bone mineral density (BMD) in Korean adults aged ≥ 50 years using the 2009 Korea National Health and Nutrition Examination Survey data. SUBJECTS/METHODS: This study was conducted in 1,808 subjects aged ≥ 50 years with BMD data in Korea. Dietary vitamin D levels were assessed by the 24-hour recall method. BMD was measured using dual-energy X-ray absorptiometry. We investigated general characteristics and the association between these characteristics, vitamin D status, and BMD. RESULTS: Vitamin D intake was significantly lower in the osteoporosis group among women (P < 0.05). Among all subjects, the higher the serum 25(OH)D concentration, the higher the whole-body total BMD (WBT-BMD), femoral total hip BMD, and femoral neck BMD (P < 0.01). In the serum vitamin D-deficient group of both the total population and women, serum 25(OH)D concentration was associated with WBT-BMD (P < 0.05). Among women with a calcium intake < 537.74 mg/day, BMD of those with a vitamin D intake > 2.51 µg/day (average intake of women) was higher than that of women with a vitamin D intake ≤ 2.51 µg/day (P < 0.001). CONCLUSIONS: Korean adults should increase their BMD by increasing serum 25(OH)D concentration. Furthermore, increasing vitamin D intake could improve BMD, especially in Korean women who consume less calcium than the estimated average requirement.

Purpose: This study was conducted to establish whether an ethanol extract of Lycium barbarum leaves (LLE) and an ethanol extract of Lycium barbarum leaves from which chlorophyll has been removed, denoted as LLE(Ch−), have a protective effect against hepatic fat accumulation. Methods: The inhibitory effects of LLE and LLE(Ch−) on liver fat accumulation were examined in C57BL/6 mice with non-alcoholic fatty liver disease (NAFLD) induced by an methionine and choline deficient diet and in HepG2 cells with palmitic acid-induced fat accumulation. Results: The plasma triglyceride, aspartate aminotransferase, and alanine aminotransferase levels were lower in the LLE(Ch−) group, whereas the plasma ALT activity decreased significantly in the LLE group. In both the LLE and the LLE(Ch−) groups, the triglyceride and cholesterol contents in the hepatic tissue were significantly reduced. A greater inhibitory effect on tissue fat accumulation was observed in the LLE(Ch−) group than in the LLE group. In HepG2 cells, LLE and LLE(Ch−) were non-toxic up to a concentration of 1,000 µg/mL. Compared to the control group, intracellular fat accumulation in the LLE and LLE(Ch−) groups were significantly reduced at concentrations of 200 µg/mL and 500 µg/mL, respectively. The expression of phosphorylated adenosine monophosphate-activated protein kinase and phosphorylated acetyl-CoA carboxylase in both LLE groups increased at the concentrations of 100 μg/mL and 500 μg/mL. The fatty acid synthase expression was suppressed in a concentration-dependent manner at 10 μg/mL. Conclusion The examined two ethanol extracts of LLE inhibit hepatic fat accumulation in NAFLD. This effect was more pronounced in the LLE(Ch−) group. Therefore, these 2 extracts have an anti-steatosis effect and can be used for NAFLD treatment.

A survey was conducted to investigate the current status of utilization of cyber nutritional information for teenagers and the reason for their need of such website content. In the four cities of Seoul, Daejeon, Gwangju and Daegu, in September and October, 2000, 1262 secondary school students were randomly selected. Survey results are summarized as follows: The participants searched for nutritional information by means of internet/PC communication for 137.0 +/- 100.6 (Mean +/- S.D.) minutes per day, mainly for the purpose of playing games, entertainment, chatting, or doing homework. Of the participants, 4.5% searched for nutritional information by means of internet/PC communication primarily for doing homework, and secondarily for reasons related to their own health or diet. Their satisfaction levels with the web sites used to obtain nutritional information was average. Needs assessments regarding the content of the web sites and the screen design showed that the teenagers wanted simple, clearly explained content, current information, easy access, less complicated screens and more use of characters. Only 8.1% of the participants had received nutritional counseling by means of internet/PC communication and 91% of them used it less than once a month, showing the very low utilization of nutritional counseling. The teenagers' main reasons for using nutritional counseling were related to their homework or diets, and their satisfaction levels regarding the counseling were below average. Poorly understood answers, and slow responses were mentioned. They had high interests in 'Diet for better growth,' 'Acne and diet,' 'Dental health and diet,' and 'Adolescent development'. These topics are mostly related to appearance. In conclusion, it is necessary to provide for teenagers, on nutritional information web sites, simple and well organized information, including simple graphics and characters, appropriate for their gender and age, as well as counseling sites offering kind and satisfying responses.
