We compared the long-term metabolic effects of equal amounts of carbohydrate from potato, rice and buckwheat on glycemic indices and blood lipids in healthy subjects. Nine healthy volunteers-2 men and 7 women were studied. All subjects ate diets based on the same-7-day rotating menu differing only in that the major source of carbohydrate (about 50% of daily total calories) came either from buckwheat, rice or potato. The study was conducted with a triple crossover design over three 7 day periods. On the morning of the 8th day, fasting blood was drawn from each subject to determine serum glucose, insulin, triglycerides, total and HDL-cholesterol. Subjects were then asked to eat breakfast with their respective carbohydrate within a 20 min period. Blood samples were drawn at 30, 60, 120 and 180 min after the start of breakfast to determine glucose and insulin levels. At 30 min the glucose response to the rice meal(7.15mmol/L) and potato meal(6.71mmol/L) were greater than the response to the buckwheat meal(5.855mmol/L) (P < 0.05). The mean area under the glucose response to the curve following the rice meal was greater than that following the buckwheat meal(P < 0.05). The insulin responses to the potato and rice meals at 30 and 60 min were greater than those to the buckwheat meal (P < 0.05). The mean area under the serum insulin response curve after the rice meal was greater than of buckwheat. Blood lipids, uric acid and glycosylated hemoglobin were not affected by the three meals. The study shows that the buckwheat meal has more beneficial effects on glycemic indices than either the rice meal or potato meal in healthy subjects.

This study was conducted to evaluate the effects of a set of 16 nutrition education lessons on the eating behaviors and nutrition knowledge of middle school students. The target was a group of 128 boys in the first year of middle school in Changwon, who took the classes from the 29th of August, 2011, to the 17th of February, 2012. The education was performed for 16 weeks using the e-learning textbook, 'Health and nutrition of youth', and a teacher's guidebook developed by the Ministry of Health and Welfare. The results were summarized as follows. Students demonstrated significant changes in their knowledge about nutrition and in their dietary behavior due to the nutrition education, and the effects were observed to be maintained for one year after education. The average nutrition knowledge score before, immediately after, and 1 year after the education was significantly increased from 13.0 before the education to 18.8 after education (p<0.001), maintaining the score of 18.5 1 year later. The eating-related questions of 'I will practice healthy eating habits in life' and 'Nutrition education is necessary to build healthy eating habits', were given a high score by the students at the last survey conducted one year later. Of course, it is not easy to change the dietary behavior of students through dietary education in schools. Nevertheless, the results of this study demonstrated that such educatcan is necessary since the habits can indeed be changed, as observed in the present study.

A diet rich in proinflammatory components and inflammation are suggested to be significant risk factors for multiple sclerosis (MS). This study aimed to investigate the association between the risk of MS and the inflammatory potential of an individual's diet and dietary diversity through pro-inflammatory/anti-inflammatory food intake score (PAIFIS) and dietary diversity score (DDS). In a hospital-based case-control study, 397 participants, including 197 patients with MS and 200 healthy participants aged over 18 years, were evaluated. The history of smoking, dietary intake, and anthropometric characteristics, including body mass index, waist circumference, total body fat, and fat-free mass were assessed. A validated 160-item semiquantitative food frequency questionnaire was used to calculate the PAIFIS and DDS scores. The mean age of the participants was 32.45 ± 8.66 years, and most were females (274, 79.4%). The PAIFIS score was significantly higher among MS patients than healthy participants (p = 0.001). Between PAIFIS and DDS, only PAFIS was significantly related to MS risk (odds ratio, 1.002; 95% confidence interval, 1.001-1.004; p = 0.001). PAIFIS, as an index of dietary inflammation, can predict MS. Further studies are needed to document these findings.

The effect of nutritional information on healthier menu choices have been reflected in previous research and nutrition policy efforts. This study further examines the relationship between healthy menu choices and three consumer characteristics - Future Orientation, Regulatory Focus, and Need for Cognition. A $3{\times}3$ experimental design was used with varying food types (burger sandwiches, sub sandwiches, and salad dressing) and the degree of nutritional information (no information, total calories only, and full nutrition information). It was found that having more nutritional information, and individuals with Future Orientation and Promotion Focus were associated with the choice of healthier menus. More specifically, those with high Consideration of Future Consequences and with Promotion Orientation switched their choices to the healthier ones with the provision of nutritional information.

Nutrition education in elementary school is confronted with the present problem, as a legal basis about obligation of nutrition education in school was clarified. Moreover, it's also important for providing evidence based scientific resources to make a study of evaluating the education effectiveness. Most studies of the nutrition education effectiveness have evaluated the changing dietary attitude and nutritional knowledge score before and after the nutrition education, and suggested the effectiveness of intervention as changing between pre- and post-treatment. Nutrition education, however, purposing long-term changes, follow-up evaluation process about the learned attitude and knowledge of nutrition education were requested. For these reasons, this study attempted to fulfilled standardized nutrition education program which use "Na Story and Food World" and "Na Story for Me", a textbook for the 1st-3rd grade and 4th-6th grade designed by KFDA, and analyzed the changes about the effectiveness of nutrition education happened over a period of time. In this study, each student was assessed their dietary attitude and nutritional knowledge by four periods, before the education, right after the education, after 3 months, and after 6 months. As a result, an average score of nutritional knowledge before the education, $70.08{\pm}17.91$, were changed significantly higher right after the education to $85.69{\pm}15.05$ (p < 0.001), but it lowered to $84{\pm}15.56$ after 3 month. After the nutrition education, students in all grades had positive dietary attitude to Na reduction (p < 0.001). However, the healthy eating attitude about Na reduction had been unable to maintain after 3 and 6 months. Therefore, the systematic reeducated program in elementary school was positively necessary to reinforce children's learning and cognitive skills to maintain healthy eating knowledge and attitude toward Na reduction.

Korean raspberry, Rubus coreanus Miquel (RCM), contains high concentrations of phenolic compounds, which prevent oxidative stress. To determine the effect of RCM on antioxidant capacity in humans, we assessed in vivo lipid oxidation and antioxidant enzyme activities from plasma in 15 healthy men. The subjects ingested 30 g of freeze-dried RCM daily for 4 weeks. Blood was taken at baseline and at the end of the study to determine blood lipid profiles, fasting plasma glucose, liver function, lipid peroxidation, and antioxidant enzyme activities. RCM supplementation had no effect on blood lipid or fasting plasma glucose concentrations but decreased alkaline phosphatase activity. RCM supplementation increased glutathione peroxidase activities (P<0.05) but had no effect on lipid peroxidation. These results suggest that short-term RCM supplementation may offer health benefits by enhancing antioxidant capacity in a healthy population.

This quantitative study was investigated to examine the relationship between severity of state-trait anxiety and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely to have an eating disorder, including anorexia nervosa and bulimia nervosa. Scores of healthy dietary behaviors were obtained by self-assessment instrument on healthy diet scale(20-item questionnaire), and severity of state-trait anxiety was calculated by state-trait anxiety inventory(Total 40- item questionnaire). In groups for each state anxiety and trait anxiety, there were divided between 50 percentile point of cumulatived scores of state anxiety and trait anxiety in all subjects. Linear regression analysis showed overall significant difference between dietary patterns(anorexia nervosa and healthy dietary behaviors) and severity of state-trait anxiety in all sex. Our results indicated that severity of state-trait anxiety may marked eating disorder symptomatology on dimensions of eating disorder prevention.

This study examines the dietary, exercise, and other daily habits of Daegu residents and how these relate to the residents' perception of their own health status, and comparatively analyzes the lifestyles and daily habits of those who perceive themselves to be healthy and those who do not. This research study used Inbody 230(Body composition analysis, Biospace, Korea) to make body and health measurements such as body composition and obesity index. Also, included in this study was a survey on the lifestyle patterns of the residents. The data from this survey was analyzed with SPSS. The results show that among the residents of Daegu, those who perceive themselves to be healthy have lower body fat and are less obese on average. With respect to dietary habits, those who believe themselves to be healthy have more regular dietary habits such as rarely skipping a meal than those who do not believe themselves to be healthy. In addition those who say they are healthy exercise more frequently and for a longer duration than those who say they are not healthy. As for daily habits, those who report they are healthy show greater satisfaction with life and suffer less from stress than those who report themselves to be unhealthy. This study demonstrates that in order to improve people's health in Korea, good dietary, exercise and daily habits need to be emphasized. Additionally, health education and health awareness programs need to be established in each region. Follow-up studies should be conducted afterwards.
