식품에서 탄수화물은 우리 몸에 열량을 주는 역할 외에도 맛을 부여하는 중요한 기능을 한다. 그러나 열량의 과잉 섭취로 인한 비만과 그로 인한 질병들로 인하여 저열량 탄수화물 소재에 대한 관심이 높아지고 있다. 폴리덱스트로스와 당알코올은 각각 2.0 kcal/g, 2.4 kcal/g의 열량을 가지므로 식품 내의 다른 탄수화물을 대체하여 사용하면 그만큼 열량을 줄일 수 있는 소재이다. 폴리덱스트로스는 저열량 소재라는 장점 이외에도 식이섬유원으로 널리 사용될 수 있어 열량을 줄임과 동시에 식이섬유를 보충할 수 있다. 당알코올은 설탕을 대체할 수 있는 감미를 가지면서도 당류에서 제외됨으로써 정부의 당류 저감 정책에 부합할 수 있는 소재이다. 또한 폴리덱스트로스와 당알코올은 열이나 산 등에 쉽해 분해되지 않고 안정한 특성이 있어 식품제조공정에 영향을 받지 않고 사용할 수 있다.

Objectives: The purpose of this study was to analyze the risk of dental caries and erosion associated with beverage consumption by measuring the sugar content and acidity of beverages for children, marketed in general food stores and cooperative living associations in Korea. Methods: Sixty types of children's beverages marketed in Korea were selected for the study. Calories, sodium, and carbohydrates in the nutrients per 100 ml, the sugar content, and pH of each beverage were measured. Frequency analysis, independent t-test, and one-way ANOVA were performed (p<0.05). Results: There was no significant difference in sugar content, calories, sodium, and carbohydrate content of regular and cooperative beverages, but the pH of cooperative beverages was significantly higher. Moreover, the mixed drinks had significantly lower sugar content, calories, and carbohydrates than fruit and juice, but the sodium content was significantly higher. Conclusions: When choosing beverages for children, caregivers should be able to easily access information about their impact on the child's oral health. Efforts should be made to maintain appropriate levels of sugar and acidity in beverages for children.

The purpose of this study is to examine the feeding and nutritional status of enteral tube-fed elderly patients. Subjects included 77 elderly hospitalized patients who had received enteral nutrition more than one week before admission. Medical records on admission and actual feeding volume were used to assess anthropometric, biochemical, and nutritional status. Most patients manifested disorders of the nervous system (93.5%) and the average duration of tube feeding was 13.9 months. The average feeding volume of formula was 1,107 mL per day and the mean ratios of calorie and protein (supplied vs. required) were 81.7% and 80.9%, respectively. At admission, 57.4% of the patients were malnourished according to the institutional criteria. Patients receiving less than 80% of the required calories were in worse nutritional status compared with those receiving more than 80% of the required calories. Body mass index, percent ideal body weight, serum albumin level and blood lipid levels (total cholesterol, HDL-cholesterol, triglyceride) were significantly lower in patients receiving less than 80% of the required calories. These results indicate the high prevalence of malnutrition and the need for increased attention and nutritional care of elderly patients undergoing long-term enteral nutrition.

Pork cutlets contains high amounts of fat and calories even though they are highly preferred among young consumers in Korea. We investigated the use of an oven cooking method using brown crumbs to replace the frying method for the preparation of pork cutlets. The average contents of fat and calories in oven cooked pork cutlets were reduced by 77.5% and 35.2% respectively, when compared to cutlets prepared using the frying method (p<0.05). These results demonstrate that pork cutlets prepared by oven cooking may be helpful to people who require dietary treatment. In a color experiment, the surface color of oven cooked pork cutlets showed no difference when brown crumbs were used (p>0.05). In an experiment for texture characteristics, the level of hardness for the oven cooked cutlets showed no difference from that of the fried cutlets (p>0.05), and the degree of batter separation also did not differ. The oven cooking method demonstrated a 65.6% improvement in pork cutlet production, and is therefore appropriate for a food service that must serve many customers in a limited time.

Purpose: The purpose of this study was to identify the nutritional status and to compare nutritional indicators by caloric intake for intensive care unit patients, Methods: The participants for this descriptive investigation were 62 patients who were admitted to medical and surgical ICUs and started on enteral feeding. Data were collected in a tertiary hospital and the patients were followed for 7 days after enteral feeding was initiated. For analysis, patients who received 80% less calories than their required level were categorized as the underfed group and patients who received more than 80% to their required level, as the adequately fed group. Results: Compared to daily requirements, the prescribed calories and protein for patients overall were 77.39% and 64.75% respectively. The level of calories and protein given was less than their prescription. However, a comparison of the underfed group and the adequately fed group, showed that there was no significantly difference in albumin, prealbumin and transferrin. Only body weight was significantly different between the groups. C-reactive protein had a significant correlation with prealbumin and transferrin. Conclusion: Underfeeding is a common phenomenon among ICU patients. Nutritional indicators such as prealbumin, albumin and transferrin may not sensitive indicators to assess nutritional status of ICU patients.

This study analyzed in nutrient contents changes of adult's favorite foods between March 2019 and July 2020 after policy implementation nutrient-poor foods based on special act on safety control of adult's dietary life in Korea. Among adult's favorite foods manufactured or sold in 2020 as well as 2019, calories and key nutrients in breads, ice creams and pizzas were improved in comparison to those in the other food groups. However, most of the changes in calories or key nutrient contents exist. The newly introduced candies, breads showed slightly greater improvements in calories and key nutrient contents than in 2019. On the other hand, some negative changes were found in newly introduced chocolates in comparison to previous ones. Overall, policy implementation on foods seemed to induce changes in nutrient contents of adult's favorite foods. In particular, nutrition education is reported to have a positive impact on adult's frequency and preference for processed foods, and more systematic and continuous nutrition education measures should be devised to help adult as consumers selectively purchase healthy foods. This research is meaningful in that it is the first study to analyze the quality changes of adult's favorite foods since the high-calorie and low-nutrient food management policy.

Purpose: The study was done to investigate Food and Nutrient Intakes of female college students and define differences between teen-age groups and women in their twenties. Method: The subjects of this study were 821 female college students. They were eighteen to twenty nine years old. Nutrient intakes were measured by the Moon, S. J. Scale (1980). Data was collected from June 13 to June, 27. Data was analyzed with the SPSS program by Chi-test, t-test and Pearson's correlation coefficients. Result: Female college students' mean intake of calories, protein, fat, and carbohydrates were $1560.7{\pm}367.71kcal,\;62.0{\pm}19.03g,\;33.1{\pm}9.85g,\;and\;253.7{\pm}57.52g$ respectively. Their mean intake of calcium, phosphorus and iron were $592.9{\pm}221.82mg,\;918.2{\pm}284.24mg\;and\;13.7{\pm}4.50mg$ respectively. Intake of calories, calcium, iron and vitamine B1 were below their Percent of Recommended Intake. Nutrient intakes showed a significant difference between age groups. Teen-age female college students had more nutrient intakes than the women in their twenties. In addition, there was a difference in food consumption behaviors between the teen-age group and the twenty-something group. Conclusion: The nutrient intake of female college students changed by age. Many teen-age female college students ate breakfast well, thus their intake of calories, protein, fat, carbohydrates, minerals such as calcium, phosporus and vitamins was significantly higher than the over twenty years old students. Teen-age female college students like fruits and sugars but over twenty years college students preferred coffee. This study can be useful in directing a dietary consumption status of women to improve nutritional health.
