This study was conducted to develop and evaluate food menus after investigating eating behaviors and food preferences of preschool children. Parents of the preschool children In 2 Gumi City day-care centers completed questionnaires in July 2003, which were used to assess eating behaviors and food preferences of their preschool children. Analysis of the questionnaires led to the development of the menus. Menus (n=10) were developed for five different categories (two menus were developed for each category) including general menu, unbalanced menu, anemia menu, obese menu, and traditional menu. The preschool children(n=656) evaluated the menus as they were provided with each them throughout October 2003. The five score scale method was used to evaluate taste, smell, looks, texture and general preference of each menu. Results in eating behaviors showed that 70.7% of preschool children had unbalanced eating behaviors. No gender based differences in eating behaviors were found, but in regard to food preferences boys tended to prefer carbonated drinks more than girls. Results indicated that among all menus, fruit ranked highest $(3.97{\pm}0.65)$ for food preference, and vegetables ranked lowest for food preference $(2.46{\pm}0.68)$. Food preference in regard to cooking process indicated the highest preference was for fried foods $(3.80{\pm}0.68)$ and the lowest preference was for raw vegetables $(2.61{\pm}1.27)$ and namul $(2.85{\pm}1.13)$. Preference for taste ranked the highest $(4.30{\pm}0.91)$ but preference for looks recorded the lowest $(3.95{\pm}0.89)$. Of all the foods in the menus, steamed tofu rated the highest for individual food item preference, while tuna sesame leaf rice rated the lowest preference. Statistical analysis of interrelationships among food taste, smell, looks, texture and general preference were significant (p<0.0l). Results from this study suggest that various factors including food taste, smell, looks, and texture influence the food preferences of preschool children. Therefore, it is concluded that by developing a variety of appetizing menus for use at home and in day-care centers, containing varied food items and cooking methods, preschool children will be encouraged to increase their food preferences and to establish appropriate eating behaviors.

Beverages based on fruit juices are among the most popular commercially available drinks. There is an ever-increasing demand for these juices in the market. Orange juice is one of the most common as well as most favorite flavor. The fruit processing industries have a tremendous responsibility of quality control. For quality evaluation estimation of various components of the juice is necessary. Sucrose, glucose, fructose, citric acid and malic acid are the prime components of orange juice. Little information is available on analysis of orange juice. However, conventional and general wet chemistry procedures are currently being used which are no longer desired by the industry owing to the time involved, labor input and harmful chemicals required for each analysis. Need to replace these techniques with new, highly specific and automated sophisticated techniques viz. HPLC and spectroscopy has been realized since long time. Potential of Near Infrared Spectroscopy in quantitative analysis of different components of food samples has also been well established. A rapid, non-destructive and accurate technique based on Near Infrared Spectroscopy for determination of sugars and organic acids in orange juice will be highly useful. The current study is an investigation into the potential of Near Infrared Diffuse Reflectance Spectroscopy for rapid quantitative analysis of sucrose, glucose, fructose citric acid and malic acid in orange juice. All the Near Infrared measurements were peformed on a dispersive NIR spectrophotometer (ELICO 153) in diffuse reflectance mode. The spectral region from 1100 to 2500nm has been explored. The calibration has been performed on synthetic samples that are mixtures of sucrose, glucose, fructose, citric acid and malic acid in different concentration ranges typically encountered real orange juice. These synthetic samples are therefore considered to be representatives of natural juices. All the Near Infrared spectra of synthetic samples were subjected to mathematical analysis using Partial Least Square (PLS) algorithm. After the validation, calibration was applied to commercially available real samples and freshly squeezed natural juice samples. The actual concentrations were compared with those predicted from calibration curve. A good correlation is obtained between actual and predicted values as indicated by correlation coefficient ($R^2$) value, which is close to unity, showing the feasibility of the technique.

This study was carried out in order to investigate the status of food and nutrient intakes depending on the types of chronic disease of the elderly at welfare centers in Seoul. The total number of subjects was 299 elderly over the age of 60 (82 men and 217 women); they were grouped by the disease status: normal, cardiovascular disease (CVD), diabetes mellitus (DM) and arthritis patients groups. The dietary intakes were obtained by a 24-hour recall and analyzed by CAN-Pro 4.0; they were then compared with the dietary reference intakes for the Korean (KDRIs). In the results of anthropometric data according to chronic disease, the waist circumference of the normal group in males and females was lower than the other groups; in particular, the normal female group showed a lower level of waist-hip ratio, body mass index (BMI) and body fat % than those of the other groups. The arthritis group showed a higher intake of milk products than the other groups (p < 0.05); consequently, calcium intake was significantly higher than that of the other groups (p < 0.001). Vitamin A intake in the arthritis group was significantly higher than the intake in the normal and DM groups (p < 0.01). Normal and arthritis groups showed significantly higher intake of zinc and copper than the CVD group (p < 0.01). In general, about 80% of the subjects in this study revealed insufficient intakes of riboflavin, vitamin C, calcium, dietary fiber, vitamin D, biotin and potassium, compared with the estimated average requirement (EAR) or adequate intake (AI). However, sodium intake of all groups was higher than the AI of KDRIs. In conclusion, nutrient intake, according to the chronic disease, showed significant difference in some of the micronutrients, vitamin A, Ca, Zn and Cu. Therefore, we suggest that dietary guidelines, such as reducing the intake of salty foods and sweet drinks and increasing the intake of foods with sufficient calcium, vitamin D and vitamin C, are necessary to the improvement of eating habits for the elderly.

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.

Objectives : The purpose of this study was to correlation between the index of dental caries in primary teeth and the habits of diet and snack which are expected to influence on the index. The subjects of this study were 165 parents of the children who visited a pediatric dental hospital located in Gyeong-gi do from Jun. 15th to Sep. 26th, 2009, and the self-report questionnaire survey was performed. Methods : A questionnaire used in a previous study was revised and completed for this study and it consisted of 15 items on general characteristic, nine items on dietary habit, and five items on snack intake habit. The collected data was analyzed using SPSS program and findings are as follows Results : 1. The index of dental caries in primary teeth by ages was that children of four years old has 4~5 with 27.5%, children of five years old has 2~3 and 4~5 with 33.3% and children of six years old has 1 and 8~9 with 25.6%, showing a statistically significant(${\chi}^2$=37.72, p<.01). 2. The frequency of brushing teeth was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=61.20, p<.001). 3. The frequency of taking snack was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=51.42, p<.001). 4. The desirability of dietary habit was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=36.51, p<.001). 5. The frequency of taking biscuit was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=67.74, p<.001). 6. The frequency of taking bread was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=29.63, p<.01). 7. The frequency of taking caramel and candy was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=38.85, p<.001). 8. The frequency of taking soft drinks was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=52.92, p<.001). 9. The frequency of taking ice-creams was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=75.07, p<.001). Conclusions : Those findings show that the children with undesirable dietary habit and higher frequency of taking snack have higher index of dental caries in primary teeth, therefore, it is considered that the regular brushing teeth and establishment of desirable dietary habit are very important for keeping health oral cavity. It is recommended that the continuous concern and repeated learning are needed in house and group of rearing infants so that the children take foods of fruits which have function of self-purification than the food of carbohydrates which has high adhesion and level of sweetness.
