Jeong Soon PYUN ; Kyung Hea LEE

Journal of the Korean Dietetic Association.2010;16(1):62-76.

This study was conducted to investigate the dietary habits and practices of mothers and their children from 3 to 6 years of age as well as the mother's attitudes about nutrition education. This study focused mainly on two areas: 1) the dietary habits and actual dietary practices of mothers and their children and 2) a mother's perception and need for nutrition education. The results of the regression analysis showed that there was a significant relationship between the dietary habits of mothers and their children's (p<0.05). There was statistical significance in total food frequency intake and the food frequency intake between the mothers and children (r=0.829, p<0.01). The results of the regression analysis showed that the mother's dietary attitude (meal regularity, meal tempo) could positively influence their children's dietary attitude (p<0.01). The mothers showed a high interest in nutrition education; 81.6% of mothers tried to apply nutrition information to their actual dietary life, 77.6% of them recognized the need of nutrition education on preschoolers' dietary life and health, and 75.2% of them wanted to participate in nutrition education program(s) for their children. The percent of mothers that wanted to be offered lectures, food practices and hand-outs were 36.9%, 18.4%, 15.5%, respectively. The combined results of this study showed that mothers sincerely recognize the need for nutrition education and they have a high and deep interest in nutrition education.

Yang Sook KIM ; Hye Kyung MOON

Journal of the Korean Dietetic Association.2010;16(1):49-61.

The purpose of this study was to determine basic information on the microbiological quality of environmentally friendly vegetables used in school foodservices. Comparisons were made on the microbiological quality of eight different kinds of vegetables grown by environmentally friendly agricultural methods and ordinary agricultural methods to determine if there were significant differences. In the raw materials, aerobic plate counts were as follows: lettuce 4.58~7.43 log CFU/g, winter plowing chinese cabbage 5.61~7.36 log CFU/g, Korean leek 5.81 log CFU/g to TNTC (too numerous to Count), cabbage 5.93~6.43 log CFU/g, sesame leaves 3.15~5.23 log CFU/g, cucumber 5.00~5.79 log CFU/g, cherry tomato 2.96~5.40 log CFU/g, paprika 1.30~3.52 log CFU/g. In the comparison of the microbiological quality between environmentally friendly and ordinary agricultural vegetables, their acceptable ratio was the same (81.3%) and the mean aerobic plate counts was not significantly different. In the comparison of the microbiological quality between the leafy vegetables and the fruity vegetables, the fruity vegetables had a 100% acceptable ratio regardless of the agricultural method used to grow them, while the leafy vegetables had an acceptable ratio of 70%. In terms of the aerobic plate counts, the leafy vegetables had significantly higher counts; the leafy vegetables 5.87+/-1.18 log CFU/g, the fruity vegetables 4.12+/-1.54 log CFU/g.

Mi Kyeong CHOI ; Yun Jung BAE ; Myung Hee KIM ; Oh Sun LEE

Journal of the Korean Dietetic Association.2010;16(1):39-48.

This study was conducted to assess the perception of nutritional education by students in elementary school and their parents in terms of the degree of satisfaction with school foodservices. The survey was conducted on 322 parents and 322 students using a questionnaire. Most of the students and parents were satisfied with the school foodservices, the most satisfactory component of school foodservice was the "balanced nutrition intake". The students and parents acquired nutritional information from the "school letter" and "Mass media". They trusted professional dietitians, the school and the nutritional information acquired from accredited mass media. In regards to the type of nutritional education, 28.9% of parents preferred "clinical nutrition information on disease" and 26.9% of parents preferred "nutrition information of food". In contrast, 33.7% of the students preferred the "clinical nutrition information on disease" and 25.4% of the students preferred "right eating habit (unbalanced eating, skipping meal)". The top three reasons for wanting to provide offspring with nutritional information was "right eating habit" (48.9%), "correction of unbalanced diet" (19.8%) and "healthy physical strength" (12.1%). The dietitians need professionalism to deliver accurate information and knowledge relating to the subjects that the users demand and the development of teaching media should be conducted to effectively deliver this knowledge.

Hee Seon CHOI ; Hyun Kyung MOON ; Hye Young KIM ; Jeong Sook CHOI

Journal of the Korean Dietetic Association.2010;16(1):22-38.

In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.

Nami JOO ; Boram KIM ; Seojin PYO

Journal of the Korean Dietetic Association.2010;16(1):13-21.

The purpose of this study was to determine the optimal mixing conditions of different amounts of Jinuni beans and fresh cream for the preparation of Jinuni bean chocolate. An experiment was designed using the central composite design of the response surface, which required 10 experimental treatments including 2 replicates for the Jinuni bean and fresh cream. The compositional and functional properties of the treatments were measured and these values were applied to the mathematical model. A canonical form and perturbation plot showed the influence of each ingredient on the mixture products. The color value L (Lightness) decreased with an increase in the amount of added Jinuni bean but the color value a (redness) and color value b (yellowness) did not change. In addition, the hardness value increased with the addition of the Jinuni bean. The results of the sensory evaluation showed very significant differences in the values of the texture (p< 0.01), taste (p<0.05), and overall quality (p<0.01). As a result, the optimum formulations as determined by the numerical and graphical methods were 27.98 g of Jinuni bean and 67.0 g of fresh cream.

Sooyoun KWON ; Sangmook LEE ; Youngmi LEE ; Jihyun YOON

Journal of the Korean Dietetic Association.2010;16(1):1-12.

This study was conducted to characterize well-being menus and to examine the service frequency and profitability of those served in the contract-managed workplace foodservice. In-depth interviews were conducted with six persons who were in charge of menu management in the headquarters of six different foodservice management companies during March, 2007. In addition, 122 set menus consisting of 777 menu items, which were on one month menus served during January to April, 2007, were collected from three workplace operations managed by three different foodservice management companies. As a result of the in-depth interviews, four categories of well-being menu items were extracted: 'medicinal, functional menu item', 'environmentally- friendly menu item', 'natural food menu item', and 'harmful components-limiting menu item'. Accordingly, a well-being menu item was defined as 'a menu item with increased nutrition value or decreased health risk by changing food material or cooking method'. When the menu items (n=777) were analyzed by applying the definition and categories, approximately 14% of the items were identified as well-being menu items and most of them were either medicinal, functional (65%) or natural food menu items (33%). Approximately 59% of the 122 set menus included at least one well-being menu item, and therefore they were named the well-being set menus. These well-being set menus, however, were not significantly different from the rest set menus in terms of profitability as measured by the contribution margin. The results of this study could be useful for foodservice management companies to develop and plan well-being menus targeting workplace foodservice operations.

Effect of Breakfast Service on Nutritional Status, Hematological Status, and Attentiveness of Children in Low-Income Families.

Jeong Sook LEE

Journal of the Korean Dietetic Association.2011;17(4):416-428.

This study was carried out to investigate the effects of breakfast service on nutritional status, hematological status, and attentiveness of children in low-income families. The subjects were 19 boys and 13 girls between 7 and 11 years old. The subjects were divided into a control group and a breakfast service (BS) group, in which 12 boys and 5 girls received breakfast from February 1 to December 31, 2010. The results can be summarized as follows: intakes of energy, protein, carbohydrate, calcium, iron, zinc, vitamin A, vitamin B2, niacin, and vitamin C in the BS group were significantly higher than those in the control group. In the BS group, the intakes of calcium, folic acid, and vitamin C were lower than 75% of recommended intake levels. There were no significant differences in the total blood protein level and total cholesterol level between the BS group and control group. A blood albumin level was significantly higher in the BS group than in the control group. Systolic blood pressure was higher in the BS group than in the control group, whereas the diastolic blood pressure showed no significant difference between the groups. A dietary attitude score increased according to breakfast service and nutritional education. No significant differences were found in the capacity value and continuity value between the two groups, but the control value was significantly higher in the BS group than in the control group. Therefore, to sustain the effect of breakfast service and improve nutritional status for children skipping breakfast in low-income families, nutrition intervention services, as well as legal and financial support by the government should be provided.

Study on Job Training for Specialty Enhancement of School Nutrition Teachers: In Gyeongbuk Area.

Kyeung Suk PARK ; Sung Hee CHO

Journal of the Korean Dietetic Association.2011;17(4):403-415.

The present study was performed to evaluate the job training needs of school nutrition teachers in order to enhance their specialty. Three hundred and forty questionnaires were distributed to school nutrition teachers working at primary and high schools in the Gyeongbuk area while 45 were distributed to professors during 2010~2011. Three hundred and two questionnaires from school nutrition teachers and 33 from professors were returned and analyzed. The rate of teachers practicing nutrition education was 54%, and the educational content was obtained mainly from the internet. The top three problems the teachers encountered were 'lack of standardized educational materials', 'inexperience of teaching', and 'insufficiency of expert knowledge'. The teachers recognized 'training program' as the best solution. However, the job training program operated immediately after teachers were appointed scored only 3.03 out of 5.00. Important contents of the training program ranked highly by the teachers were 'development of education materials', 'nutrition counseling', and 'teaching method'. The professors included 'expert knowledge' in their top three contents. Both the teachers and professors agreed to increase the frequency of 'practice' in training methods. Other factors the teachers considered to be important were high quality, diversity, ability of the instructor, training cycle, and the institution in charge. From these results, it can be concluded that efficient job training programs are needed for school nutrition teachers according to the importance of the education contents and training methods. It is therefore suggested that a cooperation committee be composed of an educator, educatee, and related personal in a local education office in order to operate the program.

Dietary Behaviors, Processed Food Preferences and Awareness Levels of Nutrition Labels among Female University Students Living in Middle Region by Breakfast Eating.

Yun Jung BAE ; Jee Young YEON

Journal of the Korean Dietetic Association.2011;17(4):387-402.

The purpose of this study was to examine the dietary behaviors, processed food preferences, and awareness levels of nutrition labels among female university students living in middle region by breakfast eating. A total of 243 students (breakfast eating group: 153, breakfast skipping group: 90) were surveyed from April to May of 2011. The results are summarized as follows: Skipping breakfast (SB) group had a significantly higher frequency of skipping lunch and dinner compared with the eating breakfast (EB) group (P<0.05, P<0.01, respectively). In the EB group, food labels were identified sometimes (31.8%), frequently (29.1%), and rarely (28.5%). In the SB group, food labels were identified rarely (33.3%), sometimes (27.8%), and frequently (26.7%). The EB group used food labels for comparing price and weight of products more frequently than the SB group (P<0.05). In the EB group, nutrition labels were identified sometimes (38.0%), frequently (28.1%), and rarely (24.8%). In the SB group, nutrition labels were identified rarely (32.6%), sometimes (30.3%), and frequently (21.4%). The EB group used food labels for identifying nutrient contents more often and for weight control more less than the SB group (P<0.05, P<0.05, respectively). The main reason for not identifying nutrition label of the processed foods was 'not being interested (55.5%)' in the SB group (P<0.05). Therefore, education programs that emphasize the importance of eating breakfast, and reading food and nutrition labels need to be developed for university students.

Yang Hee HONG ; Dong Geon KIM ; Jin Sun HURH ; Myong Ok LEE ; Yoon Sook KIM ; Un Jae CHANG

Journal of the Korean Dietetic Association.2011;17(4):378-386.

To examine the effect of obesity on volume perception according to size and color of rice bowl, we divided female college students into a normal weight group (<30% fat mass, n=100) and obese group (> or =30% fat mass, n=83) and then measured perceived volume of rice bowls of various sizes (general size; 350 ml vs. small size; 188 ml) and color (yellow, white, blue, and black) containing the same amount of cooked white rice (210 g). Normal weight group perceived that the general rice bowl contained significantly more cooked white rice compared to the small rice bowl. In contrast, the obese group perceived that the general rice bowl contained significantly less cooked white rice than the small rice bowl. The estimated variance in perceived volume of both bowls was significantly bigger in the obese group compared to the normal group. There were no differences in perceived volume among any of the subjects (both normal and obese groups) according to rice bowl color. However, the estimated variance in perceived volume in the obese group was significantly larger than that in the normal group for all of the rice bowls. In conclusion, rice bowl size and color might affect volume perception, and volume perception in obese people may be different from that of normal weight people.
