This survey was conducted to find out one serving size and waste rate of frequently consumed dishes in 37 Korean style restaurants. The range of one serving size and waste rate of Pab(boiled rice) were 180~290g and 0~21%, respectively. The mean intakes of Pab were varied according to the kind of dishes served. The waste rate of Yukgaejang(Hot meat soup) is low among Tangban(meat soups). The waste rate of Jeongol(stew with various foods) was higher than other menu items. The average one serving size per person of Pulgogi(grilled meat with sauce), Galbi gui(grilled beef ribs with sauce), Deongsim gui(grilled meat) were 270g, 360g, and 210g, respectively. The average waste rate of side dishes were varied according to dist served. The dish which has higher waste rate than other dishes were Samgaetang(boiled chicken with ginseng), Bokmaeuntang(stew with puffer), Naengmyeun(cold noodle), Pulgogi(grilled meat with sauce), Galbi gui(frilled veef ribs). The reasonable one serving size of dishes based on this survey results was suggested for serving in restaurants.

The amount of sodium in the processed foods was evaluated by the information on the nutrition label. One-meal type foods as Ramen, Woodong, Naengmyon provide the most sodium reaching 30 - 70% DV per serving size. In Ramen not much difference was observed for the sodium content by food companies though each company provides various amount of sodium reducing as much as 25% DV. The proportion of female college students who read the nutrition information reached 62% but it remained 32% on the sodium information. They purchase low sodium foods rarely however their intention to buy low sodium foods increased up to 40% in condition that sodium information is given on the food label. Neverthless 50% of them would not buy low sodium food if the taste is undesirable. Low sodium ramen cooked with 80% soup-base was acceptable by the subjects. Majority of them responded the soup was rather salty indicating the reduction of sodium in ramyeon is possible.

The aim of this study was to develop various types of a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and to evaluate the validity of a 125 item dish frequency questionnaire (DFQ 125) with the DFQ 70, DFQ 36 and DFQ 15. For the DFQ 125, one hundred and twenty five dish items were selected based on the information of sodium content of a one serving size, consumption frequency and dish items that contributed most to the variation of sodium intake. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. The sodium intake estimated with DFQ 125 was 5775.0 +/- 3636.3mg, 12.6% higher than that estimated with a 24 hr urine analysis (5009.7 +/- 1541.9mg) and significant correlation was observed between them (r = 0.3315, p < 0.001). When sodium content in broth leftover was subtracted from the total intake, the actual sodium intakes was decreased to 5309.6 +/- 3076.6mg, which was 3.2% higher than that with a 24-hr urine analysis. Overall, 56% of subjects in the lowest quintile of sodium intake computed with DFQ 125 were also in the lowest of adjacent quintile while categorization into the opposite quintile were 4.9%. DFQ 70 was developed from DFQ 125 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. The sodium intake estimated with DFQ 70 (5026.6 +/- 3107.1mg) showed only 0.2% difference from that estimated with a 24-hr urine analysis, significant correlation with it (r = 0.3199, p < 0.001) and higher proportion of subjects to be classified into the same or adjacent quintile. The sodium intake estimated with DFQ 36 or DFQ 15 was also significancy correlated with that estimated with a 24-hr urine analysis (r = 0.3441, p < 0.001; r = 0.321, p < 0.001 respectively) and more. The proportion of subjects was classified into the same or adjacent quintile. However, the actual sodium intake estimated with DFQ 36 or DFQ 15 were 3534.0 +/- 1804.6mg and 2508.0 +/- 1261.5mg, respectively, 31.3% or 51.3% less than that estimated with a 24-hr urine analysis. It seems the DFQ 125 with subtraction of sodium content in broth leftover or DFQ 70 can be used quantitatively to estimate sodium intake of adults. DFQ 36 or DFQ 15 can be used as a screening tool or to assess the changes of sodium intake after nutrition education.

This article aims to summarize the development and application of menu engineering technique, 'Menu Engineering Modified by Preference (MEMP)'. The site selected for this project was a foodservice operation in Yonsei University residence hall. Sales and food costs data were collected from the daily sales reports for 1 month, and the survey of food preference was conducted during May, 1999. Statistical data analysis was completed using the SAS/Win 6.12 for descriptive analysis. The calculation for menu analysis were carried out with MS 2000 Excel spreadsheet program. This MEMP technique developed had 6 category criteria and 2 dimensions of the contribution margin (CM) and the menu mix modified% (MMM%). The MMM% was calculated by the sales volumes and also weighted by food preference. The CM and MMM% for each item were compared with a mean menu CM as well as a 70% rule. Four possible classifications by MEMP were turned out as 'STAR', 'PLOWHORSE', 'PUZZLE', 'DOG'. 'STAR' items were the most popular and profitable items and required to maintain rigid specifications for quality. The decision actions for 'PLOWHORSE' menu items which were relatively popular, but yield a low menu average CM included combining a plowhorse item with lower cost products and reducing the frequency of serving or serving size. There was a need for 'PUZZLE' items to be changed in the menu combination, improve recipe, and promote menu. The last 'DOG' items were desired to be deleted. This study demonstrates that menu information can be interpreted more easily with MEMP. The use of MEMP is therefore an effective way to improve management decisions about menu of university residence hall foodservice.

Dietitians in various fields have used food exchange lists for food preparations. However ie seems that the present food exchange lists are complicated, thus they cause many problems for dietitians to use in the fields. Therefore this study evaluated to the extent of awareness and utilizations of KDA food exchange lists in dietitians and also collected dietitian's opinions for revising food exchange lists such as serving size, serving calories, and for unifying food guidelines and dietary and dietary guidelines for Korean to one simple guideline. 192 dietitians who presently work in urban and rural areas were recruited and data based on survey were collected. As results, most of dietitians(87.5%) knew well about food exchange lists, but only 7.8% of them always would use food exchange lists for menu planing, 56.3% of dietitians did not use it at all and 34.4% occasionally use it. And 88.0% of dietitians wanted to revise food exchange lists totally or partially, 69.8% of dietitians hoped to amend various calories per one serving in food exchange lists to one serving calorie. The desirable on serving calorie was selected as 100kcal(51%) or 50kcal(38%) by dietitians. The dietitians in this study understood very well dietary guidelines(86.5%) and food guidelines(88.5%) for Korean, and 66.1% dietitians wanted to unify both guidelines. In case of unification of guidelines, dietitians answered that 7~8 items(30%) or 5~6 items(27%) should be included in guideline. In the question about reference value for daily allowance, most dietitians(56%) satisfied with the present various reference values for various generation while 28% of dietitians wanted to change to have one reference value (standard with 2000kcal, adult female). This study will provide basic informations for revising or adjustment of food exchange list and dietary or food guidelines for Korean.

The glycemic index (GI) is the measure of how much and how quickly a particular food elevates blood glucose levels. The glycemic load (GL) is a related measurement that is used to reflect how an average serving of a particular food will affect blood glucose. Using the GI in meal planning can improve diabetes control and other health parameters. Many factors affect a food's glycemic effect, including its soluble fiber content, the type of starch it contains, its fat and protein content, its acid content, its physiologic state, the cooking method used, and the glycemic condition of the person eating it. GI focuses on only one parameter of how quickly blood glucose rises in response to a particular food and provides no guidance in terms of serving size or nutrient balance. It is not necessary to teach patients to calculate the GI/GL of complex meals made up of many different ingredients. Instead, advice to patients should focus on broad general principles that can be easily followed. The most helpful message is to not focus on the numerical GI or GL values of each meal, but rather to think about the overall glycemic impact of that particular meal. Such practical methods to use GI may be helpful in improving glycemic control.

To survey the different view points about food service programs among parents and teachers, 2 types of questionnaires, which consisted of attitude, perception, satisfaction and demand of the food service program in child education centers, were used. The data was collected from 2450 parents and 450 teachers who attended a child education center in 16 provinces, nationwide. SPSS was used for descriptive analysis and ANOVA test and chi2-test. The finding results were as follows. 1. The average serving size of meal (lunch) were 80 meals per day and 167 meals per day at large institutions. Mean cost of snacks was 14,709 won per month and mean costs of lunch were 29,319 won per month. The mean price was not significantly different according to the scale of institution. The numbers of servings of lunch, morning snack and afternoon snack were 5, 3.4 and 3.5 times per week each. 56.4% of the institutions served meals to children in classrooms, but the national/public institutions, which were attending elementary school, served meals in a dining place in the elementary school. 2. Teacher controlled serving portion size of snacks (79.6%) and lunch (88.8%) and 30.1% of teacher did not allow leaving lunch food. The ratio of knowing about preserved meals of the teacher who worked at a small institution was significantly higher than the teacher who worked at large institutions (p < 0.01). 3. Between parents and teachers, several different view points about school lunch programs were detected. Most parents and teachers wanted that the school lunch to be fully cooked and served at the child education institution itself, but 12.2% of parents and 14.4% of teachers wanted a catering service. The teachers group preferred 'lunch box from home' and 'home partially prepared lunch' as an ideal meal serving type than the parent groups (p < 0.01). And there were significantly different view points about price factors in school meals, teachers group highly answered that operating expenses must be added in meal prices. 4. The teacher groups' priorities of education activities during meal time were a significantly lower score than parents group in overall education activities. Teacher and parent groups pointed out that individual sanitation activities were most important of the education activities during meal time, but promoting good eating habits was the lowest score in both groups. 5. 'Improving taste and food quality' was most urgent in food service at child education centers, but there were significantly different view points between parent groups (64.5%) and teacher groups (43.8%)(p < 0.05). They answered at a lower percent in 'employee qualified person' and 'cost control' point to improve food service, but there were also different opinions between the two groups (p < 0.01). 6. As to the matter of the advantages and disadvantages of catering services, two group answered that the advantages of a catering service were 'convenience' and 'to solve facilities and labor problems', disadvantages were 'lower in food freshness' and 'sanitation problems'. There were also several different view pionts in catering services, the parents groups were more anxious about food sanitation than teachers. This study found several different view points about school food services among parents and teachers. To improve food services at child education institutions, there is a need to adjust the differences between the two groups through interactive communication channels and education and to employ dietitians as taking charge of adjusting roles between the two groups.

OBJECTIVES: This study was performed to set easily applicable portion sizes by sex and age for children at the Community Child Centers (CCC) in Korea. METHODS: Considering the age and gender specific energy level at Target Patterns for children aged 6-18 years, which were suggested as a part of the 2010 Korean Food Guidance System (KFGS), we set three meal sizes. We reclassified the recommended daily servings of Grains, Meat.fish.eggs.beans and Vegetables group at Target Patterns into three meal sizes, and then calculated the recommended serving per meal. Each proposed amount of food per meal was calculated based on serving size of foods commonly eaten at KFGS, which was then allocated to five meal components; rice, soup, stew, protein and vegetable side-dishes and Kimchi. Each proposed amount of food per meal was applied to 173 menus' recipes from CANpro 3.0 as main ingredient's amounts. We cooked the 173 menus at the medium size and measured their weights after cooking. RESULTS: Each recommended serving per meal was 0.75, 0.9 and 1.2 for Grains; 1.2, 1.6 and 2.4 for Meat.fish.eggs.beans; 2, 2.4 and 2.8 for Vegetables by meal sizes. Among five meal components, the ratio of small and large to medium size was 1/5 less and 1/3 more for rice and 1/3 less and 1/3 more for soup.stew, protein side-dish and Kimchi, respectively. We suggested the same amount for a vegetable side-dish to encourage vegetable intake. Proper portion sizes per meal of medium were rice 190 g, soup.stew 210 g (solid ingredients 60 g), protein side-dish 100 g (meat.eggs.beans) and 70 g (fish), vegetable side-dish 80g and Kimchi 30 g. CONCLUSIONS: Proper portion size per meal suggested in this study may be useful at the CCC where dietitians are not available and the approach could be applicable to the other types of meal services.

This study was performed to weigh the average meal portion sizes served for preschoolers by kindergarten teacher. The subjects were 53 teachers from 8 kindergartens, which are random sampled by meal service number. Using the weighing method assessed the meal portion sizes of food items at lunch. The data was complied by performing chi-square-test using SPSS WIN 11.0. The result was as followed: 98.0% of teacher agreed with the meal service because of 'better food habit and table etiquette' ( 68.0%) , 'health promotion with balanced diet' ( 22.0%) , 'owing to extending school time' ( 6.0%) and 'demand of parents' ( 2.0%) . Preschooler eat lunch at class ( 84.9%) and meal serving size was decided by teacher ( 79.2%) . Teachers thought that they know very well about portion size 3.8%, 96.2% of teacher thought that they don't know much about portion size. Portion size were not significantly different by food tray types but there was much different ( almost 100%) compared with minimum and maximum within dishes. Most average portion size was not met dietary reference intake except cooked rice, soups and fish cutlet. Working experience effected on portion size. More served, more working experienced of teacher. For example Bulgogi was served 26.8 g by teacher who has over 6 years working experience compared with 2 - 6 years ( 20.4 g) and less than 2 years ( 17.1 g)(p < 0.01) . Spinach portion size was significantly different by teacher's working experience ( p < 0.01) . Portion size were not significantly different by preschooler's age. The reference of dietary for preschooler was different by age, but teachers served meal by their exper-ience. According to the results of this study, it is necessary to educate meal portion size for kindergarten teacher who take charge in meal serving. To provide guidance to teacher about reasonable portion sizes for preschoolers, teacher need to take nutrition education about meal service and child nutrition in college. This study would be useful to those who plan meals for preschoolers and to researchers studying dietary intakes of preschooler.
