  • For the chemical assessment of soybean sprouts as a protein food, the changes of amino acid compositions were investigated in soybean as well as both in cotyledon and axis at various growing stages. The total amino acid content per soybean sprout was not changed until 2 days, and thereafter decreased. In cotyledon it is decreased but increased in axis. The ratio of essential amino acid to total amino acids decreased rapidly after 4 days, especially in axis. Aspartic acid increased considerably while glutamic acid decreased. The assessment of soybean sprout with chemical score, A/E and A/T, methods showed that the values were low and that there was no consistency among two methods for sprout products. The limiting amino acid was methionine. Both chemical scores by FAO reference protein and requirement pattern showed similar decreasing order of 2 day-sprout>soybean>4 day-sprout>8 day-sprout>6 day-sprout, while both essential amino acid index and requirement index showed 2 day-sprout>soybeans>4 day-sprout> 6 day-sprout>8 day-sprout.

  • Nutrition education should be an important component of ongoing health promotion for older adults and their caregivers. This is because prevention through sound nutrition and food hygiene practices and regular excercise is the most cost-effective way to reduce risks for and deal with their major health problems. nutritions education services should effectively promote optimum intake and successful self-care. Unfortunately, however relative to other vulnerable groups, nutrition education for older adults has not been systematically developed or evaluated. Usually oder adults care a lot about their health, so this should be a relatively easy group to teach - but their increasing numbers, longevity and great diversity with respect to health, physical, and economic status and educational level present challenges. Some older adults may not perceive they would benefit from nutrition education, so interesting and motivating them is a challenge. The food and nutrition knowledge of older people has been acquired through a lifetime of experience. For most older adults in the Asian region, their sources are restricted by their restricted education, so that their major sources of information have been informal sources, such as television, radio, friends, family, and perhaps newspapers and magazines if they are literature. Nonetheless, dietary advice for older people should build on their existing knowledge and ingrained values. It should provide information useful in daily food selection, and focus on food, not nutrients - the same foods and groups considered appropriate for younger people, with consistent messages as given throughout the population. Attention must also be paid to discovering learning styles in older people. When we teach in schools, the young students are a captive audience resigned to their learning role. Learning by an older adult, however, reflects an effort to meet his or her perceived needs. Therefore, nutrition education should be a positive experience in a non-threatening environment, relaxed and non-competitive, and perhaps even social environment. The messages also need to be practical and achievable. A needs assessment is essential, because our ability to provide the most effective nutrition education will depend on our success in matching the needs, both perceived and unperceived. of this vulnerable group. Therefore, go to the potential older learners to assess their interest and preferences. Nutrition education activities for older adults are widespread, but few have been evaluated. Evaluation is therefore also recommended, particularly when new methods are used. Tips from other countries for giving successful nutrition education will be given, including some examples of applications as attempted in Hong Kong. Research needs will also be described. In conclusion, successful nutrition education for older adults depends on positive needs-based messages. This is may be hard to do, as few good examples are available to illustrate these principles.

  • Objectives : The purpose of this study was to investigate the association between the insulin resistance and depressive mood, suicidal ideation, psychological stress, and quality of life in general Korean population. Methods : We selected 3,613 subjects from the third year's data of 6th Korean National Health and Nutritional Examination Survey. Insulin resistance was evaluated with Homeostatic Model Assessment of Insulin Resistance. Questionnaires on depressive mood, suicidal ideation and psychological stress were conducted. The quality of life was assessed with the EuroQol-5 dimension index. We used correlation and regression analysis for analysis. Results : The risk of depressive mood and suicidal ideation was significantly higher in the insulin resistance group than in the control group. The risk of psychological stress was significantly higher in the male group with insulin resistance. The EuroQol-5 dimension index showed a negative correlation with insulin resistance. After adjusting for age, sex and body mass index, increased risk of suicidal ideation was identified only. Conclusions : We confirmed that insulin resistance is associated to mental health problems related with depression in Korean adults.

  • Purpose: The purpose of this study was to assess the diet intake status and quality of adults from North Korea who had lived in Seoul and Gyeonggi-do, using the nutrition quotient (NQ) for Korean adults. Methods: A number of 166 adults aged from 20 to 64 years were enrolled as study subjects. A structured questionnaire was used to collect information on their demographic characteristics, food consumption frequency, eating behaviors, and NQ. The NQ score was then used to measure the overall diet quality. The NQ score was composed of four major age-based categories. 'Balance', 'Diversity', 'Moderation', and 'Dietary behavior' were utilized as scores for measurements within each of the four categories. The scores for all four categories were summed up, resulting in the total NQ score. Participants' age groups were stratified by 20's, 30's, 40', and over 50's. A χ2 test and generalized linear regression (GLM) model were used to assess a significance for difference of subject distribution in categorical and continuous variables in the food consumption frequency, eating behaviors, and NQ scores. Results: Participants in younger age groups were more likely to report consumption of ramyeon, fast food, sweet and greasy baked products, processed beverage, delivery food, and night snacks than the older age groups. Most importantly, participants in 20's age group were less likely to report the total NQ and moderation score than the 50's age group. Conclusion: In this study, the 20's age group displayed a lower NQ characteristic for an unbalanced diet. Therefore, it is imperative for adults from North Korea to be given individualized diet instructions along with nutritional education programs.

  • The purpose of this study was to provide information on the labeling of nutritional components on beverages to aid in nutrition education and oral health promotion. The study was conducted to evaluate nutritional effects and risk factors associated with the consumption of different beverages with respect to oral health. A total of 52 products from seven different types of beverages were analyzed for their nutrient content, sugar content, and pH. The sugar content per serving size, based on the nutrition labeling of beverages, was highest for the milk beverages, at 26.6 g, and lowest for the teas, at 13.0 g. According to the recommendation of the World Health Organization (WHO), beverages should contain less than 10% (50 g) total sugars. Our assessment revealed that total sugars in and carbonated beverages were 53.2% and 50.0% of daily value, respectively. Therefore, the milk and carbonated beverages contained more than 50% sugars per serving size, exceeding the recommendation of WHO. The pH of the beverages, from the most acidic to the least acidic were: carbonated beverages, pH 3.0; fruit and vegetable beverages, pH 3.1; mixed beverages, pH 3.6; fruit and vegetable juices, pH 3.7; teas, pH 4.7; coffees, pH 6.6; and milk beverages, pH 6.8. The intake of acidic and sweetened beverages could potentially cause dental caries and erosion. Therefore, the results of this study could be used by oral health care professionals to counsel their patients by providing relevant information on the possibility of oral disease caused by consumption of commercial beverages.

  • This study was carried out to broadly profile the dietary pattern of elderly who consumed a higher amount of sodium compared to lesser sodium consumers. Na index 14, an instant food frequency questionnaire (IFFQ) of 40 items characterizing a high amount of sodium and a food frequency questionnaire of 63 food items that were used in nationwide surveys were adopted for the assessment of dietary characteristics of the subjects. The Na index 14 consisted of food items such as kimchi stew, bean paste stew, cooked spinach dish, seaweed soup, fish stew, roasted anchovy, and seasoned vegetables. Also, the survey constructs included nutritional knowledge and anthropometric measurements of the subjects. Out a total of 135 participants, 58 elderly were determined as the high sodium intake group (HSIG) and the other 77 were the control group, via a formerly validated Na index and sodium-associated dietary habits scale (SDH). Dietary habits of "add salt or soy sauce to foods", "drink up the broth of soups and stews", and "brined fishes and vegetables daily" were among the most significant differences between HSIG and control group in SDH assessment. In addition, the HSIG were less likely to have regular meals, adequate amount of meals, and nutritionally balanced meals than the control, with the differences manifesting more in females than males. Additional findings included that the HSIG possessed a poorer nutritional knowledge and obtained much higher scores on the IFFQ. Taken together, the study urges the needs of nutrition education for the elderly who habitually salt their foods and maintain a less desirable dietary style.

  • The purpose of this study was to analyze the performance evaluation index for a salt reduction project. Questionnaires were developed in order to investigate salt reduction programs nationwide. The evaluation index and programs were analyzed through the case study of a salt reduction program in public health centers. The validity of the salt reduction program's evaluation index was determined based on study of the Delphi survey and on discussion with nutrition and health care professionals. The Delphi survey showed that daily salt intake was the most valid nutritional evaluation index. Stroke mortality and stomach cancer mortality were good health care evaluation indexes. The method for measuring salt intake that had the greatest validity was a 24-hour urine collection. However, 24-hour urine collection had the lowest score for ease of performance. The combined scores of validity and ease of performance showed that the survey method for dietary attitude and dietary behavior, dietary frequency analysis (DFQ 15), and a salty taste assessment, in that order, were proper methods. The high reliability of the salty taste assessment indicated that the percentage of the population that exhibits proper salt intake (2,000 mg sodium or less daily) and the percentage of the population that consumes low-salt diets as nutritional evaluation indexes also will be helpful to evaluate performance of salt reduction programs.

  • This study was performed to provide basic ideas as understanding and application for oriental medicinal cuisine (Yak-Sun). To develop medicinal cuisine, it is necessary to grasp the theoretical system. And to develop medicinal cuisine for health enhancement, it is also required not only to consider constitutions but also to suggest the need of knowledge for moderation in terms of regimen along with the theory of oriental medicine. Also to develop medicinal cuisine according to the perspective of oriental medicinal theory, what should be taken into account is not only the understanding of the characteristics of food materials, but also the properties of them that the theory of oriental medicine. Lastly the scientific effect of the medicinal cuisine which is developed according to the oriental medicinal theory. And it is believed to De essential for the government to make effects to set a standard and laws to validate the medicinal effects and the process of assessment so that the systematic development can be encouraged, and to prepare guidance to food development for national health improvement. This research was planned and executed to evaluate how the composition of Yak-sun(oriental diet therapy) can effect health conditions of people who are suffering from diet-related diseases like cardiovascular related disease. by taking Yak-sun in a form of nutritional supplement with our daily meals. We produced Yak-sun tea with Mansam, Hwanggi, Tanggi and Paekchak and observed nutritional composition. We concluded that we could apply the components not only in a form of tea, but also in other forms of various food. The information we received from this conclusion will be a basic information on how we can apply oriental medicinal resources into other food and will also be a steppingstone for medicinal herbs to step foot in the field of functional food research, which already draws sizable attention world-wide.

  • This study evaluated the microbial, nutritional, and rheological changes in potatoes, during storage at room, low, and freezing temperatures for 6 months. No significant changes in total aerobic plate counts were observed for any of the samples in the assessment of microbiological quality changes. For the 4 types of frozen potatoes, yeasts and molds were not found until 24 weeks. The sugar contents of the potatoes stored at room and low temperature ($10^{\circ}C$) increased during the first 4 weeks of storage, but then decreased rapidly thereafter; while those in the frozen potatoes did not change significantly throughout the 48 weeks. The vitamin C, B1, and B2 contents of the potatoes stored at room and low temperature had decreased significantly after 4 weeks of storage, however, the levels in the frozen potatoes did not change rapidly. The weight, volume, and hardness of the frozen potatoes changed much less as compared to the potatoes stored at room and low temperature over the 48 weeks of storage. Finally, the cohesiveness of all the samples, except for the frozen mashed potatoes, did not change during storage.

  • Purpose: A total gastrectomy is generally peformed for the treatment of upper third gastric cancer. However, the optimal extent of resection for early-stage upper third gastric cancer is still controversial. In this research, we compared the nutritional status and the quality of life in patients who underwent a total gastrectomy with uncut Roux en Y esophagojejunostomy with those in patients who underwent a proximal gastrectomy with esophagogastrostomy for treatment of upper third gastric cancer. Materials and Methods: We reviewed 50 patients with no evidence of recurrent disease following curative surgery for upper third gastric cancer. Among this group, 25 patients underwent a total gastrectomy (TG) and 25 patients a proximal gastrectomy (PG). 8 TG and 4 PG patients were excluded from this study because of death, refusal to interview etc. The nutritional status was assessed by measuring body weight, serum albumin, serum hemoglobin, and serum total protein. The gastrointestinal function and the quality of life were assessed by Cuschieri grading and modified Visick qrading. Results: In analysis of covariance of age and preoperative serum albumin, PG patients demonstrated lower weight loss (P=0.038), elevated serum albumin (P=0.049), and better outcome based on modified Visick grading (P=0.016) than TG, but there were no significant differences in the serum hemoglobin change (P=0.165), serum total protein change (P=0.435), and Cuschieri grading (P=0.064) between the preoperative and the postoperative data. Conclusion: In this study, a proximal gastrectomy led to a better nutritional status and quality of life than a total gastrectomy, as judged from the low weight loss, elevated serum albumin and better modified Visick grade.
