The purpose of this study was to analyze the effects of dietary life application according to preferred dietary life education type on quality of life of participants in dietary life education programs and to provide basic data necessary to enhance dietary life education. The results of the analyses conducted to classify the types of preferred dietary life education and types of dietary life application and to verify the validity and reliability of the factors are as follows. In terms of the types of preferred dietary life education, health-oriented type, knowledge-oriented type, and experience-oriented type were derived. In terms of types of dietary life application, proactive application and emotional application were derived. Knowledge-oriented type and experience-oriented type were found to affect proactive application and emotional application in terms of real-life application, and proactive application and emotional application were found to affect quality of life. Therefore, in order to enhance the dietary life education for adults in general, it is necessary to improve accessibility by initiating and promoting various programs along with continuous support from central and local governments. Moreover, in order to increase the real-life application and utilization of such programs, the importance of practical and theoretical education must be recognized, and efforts should be made in training specialized instructors.

This study was conducted to determine the elements that are required and that need improvement in the contents of dietary life education and the educational environment by analyzing the importance-satisfaction of a dietary life education program for dietary life education trainees. The results of the rank test for the satisfactory elements of dietary life education were in the order of competence of instructors, educational contents, time of education, educational environment and affordability of tuition. The importance-satisfaction analysis of the contents and construction of the dietary life education program showed that "suitable contents for the theme of the class", "contents and construction of practice class", "diversity of practice menu" and "diversity of educational contents" had high importance and satisfaction scores and therefore, could be maintained at their current levels. Meanwhile, "adequacy of class time" and "contents and construction of theory class" showed low importance and satisfaction scores, requiring a little effort. Whereas, "time and construction of group practice", "structure of textbook for class" and "duration of course and number of classes" showed relatively low satisfaction compared to importance, requiring major efforts for improvement. Similarly, analysis of the lecture element from dietary life education showed that "professional lecture by instructors", "lectures suitable for themes" and "lecture applicable in real life" had relatively low satisfaction compared to importance, requiring major efforts for improvement. In addition, analysis of the educational environment from dietary life education showed that "adequacy of lecture room space", "cooking equipment", "diversity of cooking utensils" and "sanitary condition of cooking utensils" also require major efforts for improvement. Therefore, dietary life education should not be executed with a simple delivery of knowledge but with both theory and practice classes to increase its application in real life, and active and specific efforts are required to nurture professional instructors and establish educational strategies.

This study surveyed 266 housewives residing in a Gyeonggi-provincial area for their dietary attitudes, dietary habits, nutrition knowledge, and application of nutrition information to daily life according to whether they use nutrition labeling. The survey on the dietary attitudes of the subjects showed that the points of "think that nutrition affects health", "quite interested in nutrition and health information", "like developing and trying new diverse recipes", and "persistently try new foods" were higher among those who check out nutrition labeling (Check group, n=112) than those who do not check out nutrition labeling (No check group, n=154). Reason for snacking, the Check group reported higher in the reasons of "for taking nutrients" but lower in the reasons of "do not eat enough meal" and "impulsively" than the No check group (p<0.01). Asked about why they check the nutrition labeling, the Check group answered "to compare products with each other" and "to purchase healthy food" whereas the No check group said "to decide whether the food is safe or not" and "to reduce body weight" (p<0.01). The Check group showed more recognition on the significance of the nutrition labeling and application to their actual daily lives than the No check group. Therefore, our results suggest that proper use of nutrition labeling is expected to improve dietary attitudes and dietary habits as well as enhance the application of nutrition information to actual daily life and promote health not only for the housewives but also for their family members as well.

BACKGROUND/OBJECTIVES: Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS: The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS: The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS: This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.

An educational application (App) called 'Children's Food Avatar' was developed in this study by using a food DB of nutrition and functionality from Rural Development Administration (RDA) as a smart-learning mobile device for elementary school students. This App was designed for the development of children's desirable dietary habits through an on-line activity of food choices for a meal from food DB of RDA provided as Green Water Mill guide. A customized avatar system was introduced as an element of fun and interactive animation for children which provides nutritional evaluation of selected foods by changing its appearance, facial look, and speech balloon, and consequently providing chances of correcting their food choices for balanced diet. In addition, nutrition information menu was included in the App to help children understand various nutrients, their function and healthy dietary life. When the App was applied to 54 elementary school students for a week in November, 2012, significant increases in the levels of knowledge, attitude and behavior in their diet were observed compared with those of the control group (p < 0.05, 0.01). Both elementary students and teachers showed high levels of satisfaction ranging from 4.30 to 4.89 for the App, therefore, it could be widely used for the dietary education for elementary school students as a smart-learning device.

Dietary fiber naturally present in various sources of cereals, legumes, fruits and vegetables plays a physiological role in human health, such as lowering cholesterol and blood pressure, improving blood glucose control in diabetes, helping with weight loss and management, and reducing cancer risk. In addition, dietary fibers have has been added as a functional food ingredient to food products to provide water-holding capacity, viscosity, gel-forming ability, and fat-binding capacity to food products. These beneficial characteristics of dietary fiber components can improve the image of meat products to be healthy and functional food products. This article reviews the concept and current definition of dietary fibers in food products along with their health benefits and functional characteristics. Dietary fibers from different sources like cereals, legumes, fruits, and vegetables and soluble dietary fibers have been applied as functional ingredients to various types of meat products, such as beef patties, ground beef and pork, pork and chicken sausages, meatballs, and jerky etc. Based on the application of dietary fibers to different types of meat products, possible future characteristics in selecting appropriate dietary fiber ingredients and their proper incorporation are explored to develop and produce healthy and functional meat products with high dietary fiber contents.

Background: Mobile applications (apps) on dietary supplements can increase consumers' access to information. However, it can lead to indiscriminate use of dietary supplements. This study aims to systematically review dietary supplement apps released in English and Korean and evaluate the quality of those apps. Methods: Through the app stores, apps on dietary supplements were systemically searched and examined. Two independent evaluators evaluated the apps and presented a mean score using the Mobile App Rating Scale (MARS). The correlation between MARS scores, user and evaluator ratings, and the number of secondary features of the apps were analyzed. Results: Of the 2,772 dietary supplement apps identified, 17 apps were included according to the selection criteria. The mean MARS score was 3.28 (standard deviation: 0.29) out of 5. Apps had higher scores in aesthetics and functionality dimensions, while engagement and information dimensions had lower scores. There was a positive correlation between the number of app downloads and information among MARS dimensions. The subjective evaluation also correlated with the information dimension. There was a positive correlation between the secondary features of the apps and MARS total score as well as the engagement dimension. Conclusion: The dietary supplement apps need to be managed at a higher level of quality to provide safe and reliable information to consumers. Especially, quality on information and engagement dimensions can be improved. Involvement of healthcare professionals in the app development, management with adequate referencing of information, and use of secondary features for enhanced user engagement can be helpful.

We investigated the quality characteristics of fermented ginseng Yakju produced using different percentage contents and application dates of ginseng. Although the pH of fermented ginseng Yakju was not significantly different among the various treatment groups, the total acidity was changed depending on the percentage of ginseng content. the application date of ginseng did not influence the total acid content. The amount of volatile acids was higher at a 0.2~0.3% content of white or red ginseng than in other treatment groups. The ginsenoside contents of white and red ginseng used for making ginseng Yakju were 3,555.0 and 4,447.4 ppm, respectively. In ginseng Yakju, total ginsenoside contents were detected at very small amounts of <10 ppm. A total of 15 volatile components were detected in ginseng Yakju. Higher levels of methanol were produced at early application dates. In sensory evaluations, the preference for aroma was higher at white ginseng levels of 0.5% and 1.0% than for other treatment groups, and the taste was judged to be best at a white ginseng content of 0.3%. In the red ginseng treatment group, a red ginseng content of 0.3% was most preferred for both aroma and taste. The taste preference for white ginseng was at 4 days after application, while the taste of the red ginseng treated group was good at the beginning of fermentation.
