PURPOSE: This study analyzed the foodservice satisfaction and menu preference of 506 high school boarding students in Jeju surveyed from July 2-30, 2012 with the aim of providing basic data for improving the quality of boarding food-service management. METHODS: The data were analyzed using descriptive analysis, t-test, and Pearson's correlation coefficients, using the SPSS Win program (version 12.0). RESULTS: Regarding satisfaction with dormitory foodservice, the satisfaction scores for service and hygiene were 3.46 (out of 5 scales), whereas the score for menu quality was 3.26 points. In terms of satisfaction by meal, dinner showed the highest score, at 3.70 (out of 5 scales). The satisfaction scores for breakfast were significantly higher in girls (3.36) than boys (2.93). Regarding intake of meals provided, dinner showed the highest score, at 3.96 (out of 5 scales), whereas breakfast showed the lowest score, at 3.63 points. Intake of lunch and dinner was significantly higher in boys (4.12, 4.17, respectively) than girls (3.72, 3.76, respectively). Regarding the requirements of subjects for dormitory foodservice, 43.4% of subjects selected improvement of food taste and 36.6% of girls chose menu diversity. In terms of menu preferences for main dishes, the students preferred noodles (4.06) and one-dish cooked rice (3.92) to cooked rice (3.66). The subjects preferred beef rib soup (4.10) and Kimchi stew (3.99) in soups and stews. With regard to the menu preferences for side dishes, steamed foods showed the highest score, at 3.95 (out of 5 scales), whereas seasoned foods showed the lowest score, at 2.89 points. The students preferred beef, pork, and chicken to fish and vegetables. The students preferred dessert the most with fruit juices (4.52). Bread and rice cake were more favored by girls, showing significant differences between boys and girls (p < 0.05, p < 0.01, respectively). CONCLUSION: Development of a systematic nutrition education program that can encourage practice of proper eating habits is needed. In addition improvement of the quality of boarding school meals through the service of various menus is needed.

PURPOSE: This study was conducted in order to analyze the dietary habits and food intake status according to the prevalence of depression in adults. METHODS: A total of 496 subjects, 224 men and 272 women aged 50 to 100 years were recruited from more than 13 cities in Korea. The questionnaires consisted of general characteristics, dietary life status, food intakes, the mean mini dietary assessment and satisfaction with food-related life questionnaire of the subjects to ask according to the degree of depression. Depression status was evaluated according to the Korean form of the Geriatric Depression Scale (K-GDS). RESULTS: All subjects were divided into depression or normal groups; the prevalence of depression was 13.8% (male) and 23.9% (female). People aged 65 or older were more likely to have higher prevalence of depression and to be bereaved. People in the depression group had poor appetite, almost never dined-out, and ate alone. The food intake of miscellaneous cereals, beans, tofu, chicken/duck meat, cabbage, carrot/amber, fungi, apple, pear, strawberry, grapes, and banana was significantly higher in the normal group compared with the depression group. In particular, significantly higher intake of vegetables and fruits was observed in the normal group. In addition, subjects in the depression group ate more fatty meat and were more dissatisfied with food-related life than those in the normal group. CONCLUSION: The results of this study imply that the prevalence of depression may affect the dietary habits, food intake, and dietary behaviors in the older adult population.

3.A study of the major dish group, food group and meal contributing to sodium and nutrient intake in Jeju elementary and middle school students.
Journal of Nutrition and Health 2014;47(1):51-66
PURPOSE: The objective of this study was to investigate the differences of sodium intake in the diet according to the kind of meal, food group, and dish group. METHODS: A dietary survey was conducted using the 24-hour recall method from April to May, 2009. The study subjects consisted of 701 elementary and 1,184 middle school students in the Jeju area. Mean sodium intake and the percentage contribution of meals and each dish and food group to daily sodium intake were calculated. RESULTS: The daily sodium intake was 2,868.4 mg and 3,032.5 mg in elementary and middle school students. For elementary school students, breakfast, lunch, dinner, and snack provided approximately 18.0%, 35.1%, 32.8%, and 14.1% of total daily sodium intake, and for middle school students, 15.3%, 40.2%, 29.1%, and 15.5%, respectively. Major food groups for sodium intake were spices (1,252.5 mg in elementary, 1158.0 mg in middle school students), vegetables and their products (409.0 mg, 495.6 mg), cereal and grain products (322.4 mg, 647.8 mg), and fish and shellfish (255.3 mg, 336.6 mg). Except cereal and grain products, sodium intake of the food groups mentioned above was greater at lunch and dinner than at breakfast and snack. And, the elementary and middle school students obtained 5.9% and 9.8% of total daily sodium intake from cereal and grain products at snack. Among the 29 dish groups, the highest dish groups contributing to dietary sodium intake were soup and stew and tang/jeongol, consuming 19.8% (elementary school students) and 25.4% (middle school students) of daily sodium intake. The following major dish groups contributing to dietary sodium intake, in order, were kimchi, seasoned vegetables, grilled dish, stir-fried dish, and a la carte. By meals, the percentage of sodium intake from soup, kimchi, stew, fried dish, and stir-fried dish at school lunch was high, from noodles, grilled dish, and a la carte at dinner, and from bakery/snacks and noodles at snack. CONCLUSION: Sodium intake from the various side dishes at school lunch was high and noodles and bakery/snacks were popular snack foods in elementary and middle school students in Jeju area. In order to lower the intake of sodium, students need to be educated about eating less soup and choosing better snacks.

PURPOSE: Ginger (Zingiber officinale) has been widely used as an antiemetic agent. This systematic review was aimed at evaluation of the effect of dried ginger powder supplementation on improvement of nausea and vomiting associated with early pregnancy or motion sickness. METHODS: We searched Pubmed, Cochrane, Science Direct, and KISS (Korean studies Information Service System) using keywords such as ginger or Zingiber officinale in combination with nausea, vomiting, motion sickness, or pregnancy, published in March 2013. RESULTS: The strength of the evidence was evaluated on the selected 12 RCTs (randomized controlled trials). Eleven trials including 2,630 subjects showed that supplementation with dried ginger powder resulted in significant improvement of nausea or vomiting related to early pregnancy or motion sickness. Among the nine studies including 809 women in early pregnancy before 20 weeks of gestation, ginger supplementation was superior to placebo in five studies (n = 305), and as effective as positive control (vitamin B6 or dimenhydrinate) in four studies (n = 504). Ginger intake significantly reduced the episodes or severity of vomiting related to motion sickness compared to placebo or showed the same effect as several antiemetic drugs in two studies (n = 1,821). CONCLUSION: Our findings added evidence indicating that ginger powder supplements might improve the symptoms of nausea or vomiting related to early pregnancy or motion sickness without significant adverse events.

PURPOSE: Elevated serum phosphorus and potassium levels are a major problem for hemodialysis (HD) patients. Hyperphosphatemia and hyperkalemia are closely related to intake of dietary phosphorus and potassium. METHODS: This study was conducted in order to investigate the effects of food consumed on serum phosphorus and potassium levels in 48 HD patients (20 males and 28 females). We collected anthropometric data, biochemical parameters, and dietary data of the subjects. Dietary data for usual intake were obtained by use of a food-frequency questionnaire (FFQ) consisting of 21 food items. RESULTS: The mean body mass index (BMI) was 22.2 +/- 3.0 kg/m2, mean serum phosphorus level was 4.50 +/- 1.52 mg/dl, and mean serum potassium level was 4.74 +/- 0.73 mEq/l. Hyperphosphatemia (> 4.5 mg/dl) was found in 45.8% of subjects, and hyperkalemia (> 5.0 mEq/l) in 35.4%. Subjects who took medication only were 56% of total, and those who took medication with dietary therapy were 27%. Patients with medication and dietary therapy showed significantly lower serum phosphorus levels compared to patients with medication only (p < 0.05). Mean duration of HD was 7.9 +/- 7.3 years and it showed positive correlation with serum potassium levels (p < 0.05). Serum phosphorus levels showed positive correlation with intake of mixed grains and soybean milk (p < 0.05). Serum potassium levels showed positive correlation with intake of mixed grains (p < 0.01), potatoes, fish, and high-potassium vegetables (p < 0.05). On the other hand, intake of white rice showed negative correlation with serum potassium levels (p < 0.05). CONCLUSION: The results of our study suggest that intake of white rice rather than mixed grains is an important factor in sustaining normal serum phosphorus and potassium levels. In addition, limiting intake of soybean milk, potatoes, and fish to under three serving per week is recommended. Finally, conduct of a strict dietary therapy along with medical treatment is desirable because inappropriate food intake increases serum phosphorus and potassium levels to a higher than normal range.

PURPOSE: This study was conducted in order to investigate the effect of Sargassum confusum extracts on the reduction of body fat for eight weeks in overweight women (BMI > or = 23 kg/m2). METHODS: Subjects were classified by double-blind randomized trial as the control group (C group, n = 14) and the Sargassum confusum extract supplementation group (SC group, n = 16), which consumed 12 tablets per day. Questionnaires related to their health status were assessed twice (week 0 and week 8). Their dietary intake status was evaluated by 24-recall method and body compositions were measured using a bioelectrical impedance analyzer. In addition, we assessed the anti-obesity effect and the occurrence possibility of health risk factors during the supplementation periods by hematological and clinical analysis of blood. RESULTS: Waist circumference and body fat (%) were significantly decreased in the SC group. Serum leptin level was also significantly decreased in the SC group. Defecation frequency was significantly increased in the SC group. The above results indicate that Sargassum confusum extract supplementation improves overweight on visceral fat and blood leptin level by increasing bowel movement. These results imply a decrease of health risk factors in overweight women. Seven subjects withdrew from the study due to adverse events; however, no differences regarding adverse events were observed between the control and treatment group. CONCLUSION: Therefore, Sargassum confusum extract is a plausible effective agent for body fat reduction in humans.

PURPOSE: This study was conducted to establish the production conditions through optimization of the production process of beverages using Aspergillus oryzae CF1001, and to analyze volatile compounds and antidiabetic activity. METHODS: The optimum condition was selected using the response surface methodology (RSM), through a regression analysis with the following independent variables gelatinization temperature (GT, X1), saccharogenic time (ST, X2), and dependent variable; DeltaE value (y). The condition with the lowest DeltaE value occurred with combined 45 min ST and 50degrees C GT. The volatile compounds were analyzed quantitatively by GC-MS. RESULTS: Assessment of antidiabetic activity of saccharogenic mixed grain beverage (SMGB) was determined by measurement of alpha-glucosidase inhibition activity, and glucose uptake activity and glucose metabolic protein expression by reverse transcriptase polymerase chain reaction (RT-PCR) and western blot analysis. Results of volatile compounds analysis, 62 kinds of volatile compounds were detected in SMGB. Palmitic acid (9.534% ratio), benzaldehyde (8.948% ratio), benzyl ethyl ether (8.792% ratio), ethyl alcohol (8.35% ratio), and 2-amyl furan (4.826% ratio) were abundant in SMGB. We confirmed that alpha-glucosidase inhibition activity, glucose uptake activity, and glucose-metabolic proteins were upregulated by SMGB treatment with concentration dependent manner. CONCLUSION: Saccharogenic mixed grain beverage (SMGB) showed potential antidiabetic activity. Further studies will be needed in order to improve the taste and functionality of SMGB.

PURPOSE: Several studies have proven that EGCG, the primary green tea catechin, and glucosamine-6-phosphate (PGlc) reduce triglyceride contents in 3T3-L1 adipocytes. The objective of this study is to evaluate the combination effect of EGCG and PGlc on decline of accumulated fat in differentiated 3T3-L1 adipocytes. METHODS: EGCG and PGlc were administered for 6 day for differentiation of 3T3-L1 adipocytes. Cell viability was measured using the CCK assay kit. In addition, TG accumulation in culture 3T3-L1 adipocytes was investigated by Oil Red O staining. We examined the expression level of several genes and proteins associated with adipogenesis and lipolysis using real-time RT-PCR and Western blot analysis. A flow cytometer Calibar was used to assess the effect of EGCG and PGluco on cell-cycle progression of differentiating 3T3-L1 cells. RESULTS: Intracelluar lipid accumulation was significantly decreased by combination treatment with EGCG 60 microM and PGlc 200 microg/m compared with control and EGCG treatment alone. In addition, use of combination treatment resulted in directly decreased expression of PPARgamma, C/EBPalpha, and SREBP1. In addition, it inhibited adipocyte differentiation and adipogenesis through downstream regulation of adipogenic target genes such as FAS, ACSL1, and LPL, and the inhibitory action of EGCG and PGlc was found to inhibit the mitotic clonal expansion (MCE) process as evidenced by impaired cell cycle entry into S phase and the S to G2/M phase transition of confluent cells and levels of cell cycle regulating proteins such as cyclin A and CDK2. CONCLUSION: Combination treatment of EGCG and PGlc inhibit-ed adipocyte differentiation through decreased expression of genes related to adipogenesis and adipogenic and cell cycle arrest in early stage of adipocyte differentiation.
