Balanced intake of appropriate nutrients is the key to sustaining and promoting health as well as preventing and treating diseases. It is not always easy, however, to take balanced nutrition and various related factors must be taken into consideration. This report provides a summary of studies that have examined the nutrient intakes of Japanese middle-aged men and the relationship of this intake to drinking, job-related separation from families, and health practices. The alcohol consumption of Japanese middle-aged men has more than tripled in the last forty years. When nutrient intake was examined in relation to alcohol consumption, it was discovered that the maximum acceptable alcohol consumption was approximately 23 grams (about two drinks) of pure alcohol, provided the level of nutrient intake for drinkers was equal to that of non-drinkers. The alcohol energy ratio was approximately 5％. It was also discovered that middle-aged men's eating habits deteriorate when they relocate to new posts without their families and live by themselves. Compared to those living with their families, a higher proportion of those living alone have unfavorable eating habits including skipping breakfast or lunch, having a late lunch, and eating and drinking after dinner until bedtime. When Breslow's seven health practices, nutrient intake, and consumption weight by food group were examined, it was discovered that the group that had many beneficial eating and living habits consumed plenty of legume, pulses, fruit, green yellow vegetables and milk products. Their intake of vitamins and minerals was high and the results of a physical examination proved to be excellent. According to nutrition surveys conducted in Japan, China, the United Kingdom and the United States using a 24-hour recall method with common protocols and strict controls to ensure high levels of accuracy and cross-study validity, the Japanese had the highest cholesterol intake and the lowest dietary fiber intake among the four countries. Also, the alcohol energy ratio of the Japanese exceeded 8％, the highest among the four countries, while their intake of magnesium and iron was the lowest These results indicate that it is necessary to enhance nutritional education for middle-aged men and to reinforce the social environments in which they live and work in order to promote proper diet and nutrition in Japan.

BACKGROUND/OBJECTIVES: Soy isoflavone (SIF) and soy lecithin (SL) have beneficial effects on many chronic diseases, including neurodegenerative diseases. Regretfully, there is little evidence to show the combined effects of these soy extractives on the impairment of cognition and abnormal cerebral blood flow (CBF). This study examined the optimal combination dose of SIF + SL to provide evidence for improving CBF and protecting cerebrovascular endothelial cells. MATERIALS/METHODS: In vivo study, SIF50 + SL40, SIF50 + SL80 and SIF50 + SL160 groups were obtained. Morris water maze, laser speckle contrast imaging (LSCI), and hematoxylin-eosin staining were used to detect learning and memory impairment, CBF, and damage to the cerebrovascular tissue in rat. The 8-hydroxy-2'-deoxyguanosine (8-OHdG) and the oxidized glutathione (GSSG) were detected. The anti-oxidative damage index of superoxide dismutase (SOD) and glutathione (GSH) in the serum of an animal model was also tested. In vitro study, an immortalized mouse brain endothelial cell line (bEND.3 cells) was used to confirm the cerebrovascular endothelial cell protection of SIF + SL. In this study, 50 µM of Gen were used, while the 25, 50, or 100 µM of SL for different incubation times were selected first. The intracellular levels of 8-OHdG, SOD, GSH, and GSSG were also detected in the cells. RESULTS: In vivo study, SIF + SL could increase the target crossing times significantly and shorten the total swimming distance of rats. The CBF in the rats of the SIF50 + SL40 group and SIF50 + SL160 group was enhanced. Pathological changes, such as attenuation of the endothelium in cerebral vessels were much less in the SIF50 + SL40 group and SIF50 + SL160 group. The 8-OHdG was reduced in the SIF50 + SL40 group. The GSSG showed a significant decrease in all SIF + SL pretreatment groups, but the GSH showed an opposite result. SOD was upregulated by SIF + SL pretreatment. Different combinations of Genistein (Gen)+SL, the secondary proof of health benefits found in vivo study, showed they have effective anti-oxidation and less side reaction on protecting cerebrovascular endothelial cell. SIF50 + SL40 in rats experiment and Gen50 + SL25 in cell test were the optimum joint doses on alleviating cognitive impairment and regulating CBF through protecting cerebrovascular tissue by its antioxidant activity. CONCLUSIONS: SIF+SL could significantly prevent cognitive defect induced by β-Amyloid through regulating CBF. This kind of effect might be attributed to its antioxidant activity on protecting cerebral vessels.

This study was designed to obtain the information concerning food intake, dietary habits, functional status, health condition and cognitive status of the elderly using public health center in Ulsan area. The subjects of this study consisted 154 elderly persons aged 60~82 years. Interviews were conducted using the health habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food intake, dietary cholesterol intake (cholesterol index), functional status, cognitive function and blood analysis of the subjects. The results of this study were as follows : Mean age of the subjects was 68.7 $\pm$ 6.7years. The average cognitive status score of the subjects was 7.9 $\pm$ 2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and living condition. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects had a lower cognitive status score. And hemoglobin level, serum triglyceride, HDL-cholesterol and atherogenic index affected to cognitive status while fasting blood glucose and LDL-cholesterol did not any effect on cognitive status. These results have demonstrated that various socioeconomic variables and food intake pattern and nutritional status affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.

This study was carried out to examine the effects of nutrition education program developed by Jincheon Public Health Center on preschool children's nutrition knowledge and dietary habits and the parents' dietary attitudes. The subjects of this study were five- and six-year-old children as well as their parents. A 5-week nutrition education program was implemented to 104 children in five day care centers, and 107 children in three day care centers were investigated as a control group. Activity tools designed for each lesson such as puzzles, food magnets, story, songs, Pierrot costume, and balls were used. Nutrition knowledge and dietary habits of children and dietary attitudes of parents were evaluated before and after education. Mean nutrition knowledge score in the education group was significantly higher than that in the control group after education (p < 0.001). Mean dietary habit score of three questions (three meals a day, eating at fixed time, eating breakfast) in the education group was also significantly higher than that in the control group after education (p < 0.01). In addition, parents in the education group showed significantly higher mean dietary attitude score than those in the control group even though they did not receive education (p < 0.001). Our nutrition education program was found to be effective in improving nutrition knowledge and dietary habits in preschool children as well as improving dietary attitudes in their parents.

Health Belief Model is a socio-psychological theory of decision making to individual health-related behaviors. This study was aimed to develop an effective education program for hypertension based on health belief model. The main factors of health belief model were investigated by focus group interview (FGI) with 23 hypertensive or prehypertensive subjects aged over fifty years. 'Perceived susceptibility' to hypertension was family history, neglect of health care, preference for salty food, broth of soup and stew. Lifelong medication, complications, and medical costs were reported as 'perceived severity' of hypertension. 'Perceived benefits' of hypertension management were decrease of medicinal dose, reduction of medical costs, and healthy eating habits of the family, while 'perceived barriers' were lack of palatability of low salt diet, convenience-oriented dietary habits, and limited choice of foods when eating out. Subjects mentioned TV health programs, public health center programs, and advice from doctors and family as 'cues to action' of hypertension management. These qualitative information provided basis for developing a nutrition education program for hypertension which could be implemented in the public health center. Eight week program was composed of understanding hypertension, risk factor management (eating habits, weight), low salt diet (principles, cooking), advanced management for healthy diet in 2 sessions, and summary. Each session was designed to alert the susceptibility and severity, to emphasize the benefits, and to reduce the barriers by providing dietary monitoring, practical advice, and action tips.

Background: The objective of this study was to investigate antioxidant and anti-inflammatory activity of cabbage phytochemicals. Materials and Methods: Color coordinates were evaluated by colorimetry, and the antioxidant and anti-inflammatory activities were analyzed by spectrophotometer for some common cabbage varieties. Results: Red heads had the highest total antioxidant contents followed by Savoy, Chinese and green heads. The Chinese variety had the highest ABTS (2,2-azino-di-(3-ethylbenzthiazoline-sulfonic acid) antioxidant activity, was 5.72 ${\mu}mol$ TE/g fw (Trolox equivalent). The green variety had the highest DPPH (free radical scavenging activity) antioxidant activity, which was 91.2 ${\mu}mol$ TE/g fw. The red variety had the highest FRAP (ferric reducing antioxidant power) antioxidant activity, which was 80.8 ${\mu}mol$ TE/g fw. The total phenol amounts were 17.2-32.6 mM trolox equivalent antioxidant capacity (TEAC) and the total flavonoid amounts were 40.0-74.2 mg quercetin per gram. Methanolic extracts of different cabbage heads showed different anti-inflammatory activity values. Chinese, Savoy and green heads had the highest anti-inflammatory activity, while red heads had the lowest. Conclusions: The results suggest that these varieties of cabbage heads could contribute as sources of important antioxidant and anti-inflammatory related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.

Research and development (R&D) is very important to acquire new knowledge in various fields. The significance of public R&D is also increasing, especially related to health policy making, establishing basic databases, and enhancing basic and clinical science. The total budget of general public R&D in Korea was approximately ten billon US Dollars in 2008, but the proportion of health care research was just below 10%. In private sectors, it was three times the amount allocated to the public budget. In this article, recent trends in public R&D in Korea, especially related to health care policy and biotechnology are summarized. A brief overview of the application process for a specific policy fund is also described for early-stage researchers in these fields.
