Objectives: Rapid economic growth and industrial development in South Korea have led to a great change in dietary patterns, and the use of convenience foods has continuously increased. This study was performed to evaluate the energy and nutrient contents of convenience foods at convenience stores near the universities as a meal. Methods: Data was collected by visiting 22 convenience stores near some universities in Chungbuk and Seoul and by checking nutrition labels on convenience foods at the stores. Data of a total of 338 food items were collected, and divided into five groups according to the food categories; rice products (n=156), noodles (n=101), burger/sandwiches (n=62), Tteokbokkis (n=11), and dumplings (n=8). Further, rice products, noodles, and burger/sandwiches were divided into subcategories. Results: The proportion of calories from carbohydrates was high in the rice products and tteokbokki, while the rate of calories from fat was high in burger/sandwiches and dumplings. Among the rice products, the proportion of carbohydrate calories was high in a one-dish food, rice with soup, and triangular kimbap, while the proportion of calories from fat in lunch boxes was high. In the noodles category, ramyeon and spaghetti had a high percentage of fat calories, while udong had a high percentage of carbohydrate calories. The ratio of the calorie content in relation to the KDRIs for adults aged 19-29 years, lunch boxes provided about 1/3 of daily required energy. However, the amount of calories as one meal was not enough for other types of rice products except for lunch boxes. Ramyeon was high in calories, fat, and sodium, but low in protein content. The burger/sandwiches had a high percentage of fat and sodium. Conclusions: Our results showed several nutritional limitations of convenience meals in convenience stores according to the type of food. Therefore, college students should limit excessive intake of convenience meals on a regular basis in order to avoid unhealthy food intake patterns. Our results demonstrate the need for educating college students with regard to checking nutrition labels when choosing convenience meals in order to facilitate the selection of food items that contribute to a balanced diet.

본 연구에서는 한국인이 평소 섭취하는 일반식사와 유사한 수준의 당부하량을 가진 high GL 식사와 당부하량이 낮게 설계된 low GL 식사를 섭취한 후 체중, 체지방, 혈압 및 혈액 내 생활습관병 위험 지표 등의 변화를 분석 및 비교하였다. 20대 성인남녀를 대상으로 체중 감량을 위해 wash-out 기간인 중간 2주를 제외하고 개인 필요 열량의 30%를 줄인 low GL 식사와 high GL 식사를 각 2주간 제공하였다. Low GL 식사와 high GL 식사의 효과를 비교한 결과 low GL 식사가 high GL 식사에 비해 체중 (p < 0.001), 체지방량 (p = 0.024), 체질량지수 (p < 0.001)에서 유의적으로 감소량이 더 컸다. 하지만 혈압, 혈액 내 비만 질환 위험 지표에서는 유의한 차이가 없었다. Low GL 식사의 전·후를 비교한 결과 체중, 체지방량, 체질량지수, 체지방률, 이완기 혈압, 중성지방, 총콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, 공복혈당, C-peptide HOMA 지수가, high GL 식사에서는 체중, 체지방량, 체질량지수, 총콜레스테롤, HDL-콜레스테롤, 공복혈당, C-peptide, C-peptide HOMA 지수에서 각 식사 전보다 후에 유의적으로 감소되었다. 또한 실험 식사 섭취 전과 섭취 후를 비교한 결과 체중, 체지방량, 체질량지수, 체지방률, 혈압 (수축기, 이완기), 총콜레스테롤, HDL-콜레스테롤, LDL-콜레스테롤, 공복혈당, 당화혈색소, C-peptide, C-peptide HOMA 지수가 모두 유의적으로 감소되었다. 본 연구 결과 체중감량 및 생활습관병 위험을 줄이기 위해서는 단순히 섭취 열량을 낮추기보다는 열량과 함께 당부하량을 고려하여 섭취하는 것이 체중을 감소시키는 데에 더 효과적일 것으로 사료된다.

Defatted bovine liver (DBL) is a potential source of protein and minerals. Supercritical carbon dioxide ($SC-CO_2$) and a traditional organic solvent method were used to remove lipid from bovine liver, and the quality characteristics of a control bovine liver (CBL), bovine liver defatted by $SC-CO_2$ ($DBLSC-CO_2$) at different pressures, and bovine liver defatted by organic solvent (DBL-OS) were compared. The $DBLSC-CO_2$ samples had significantly higher (p<0.05) protein, amino acid, carbohydrate, and fiber contents than CBL and DBL-OS. There was a higher yield of lipid from CBL when using $SC-CO_2$ than the organic solvent method. SDS-PAGE analysis demonstrated that the CBL and $DBLSC-CO_2$ had protein bands of a similar intensity and area, whereas DBL-OS appeared extremely poor bands or no bands due to the degradation of proteins, particularly in the 50 to 75 kDa and 20 to 25 kDa molecular weight ranges. In addition, $DBLSC-CO_2$ was shown to have superior functional properties in terms of total soluble content, water and oil absorption, and foaming and emulsification properties. Therefore, $SC-CO_2$ treatment offers a nutritionally and environmentally friendly approach for the removal of lipid from high protein food sources. In addition, $SC-CO_2$ may be a better substitute of traditional organic solvent extraction for producing more stable and high quality foods with high-protein, fat-free, and low calorie contents.

The present study was conducted to evaluate the food and nutrients intakes of stomach cancer patients in the Daegu and Gyeongbuk areas in order to find out the dietary risk factors for stomach cancer. The subjects of the study were 102 patients who had recently been diagnosed with stomach cancer at the Gyeongbuk National University Hospital. The control subjects were 105 people including patients from the Department of Orthopedic Surgery and healthy volunteers who did not have any gastrointestinal diseases. Estimates of nutrients intakes were determined from the food intake frequency data obtained by individual interviews using questionnaires. The mean daily calorie intakes of the control and the case groups were not significantly different. However the energy intake from protein was significantly higher in the case group as compared to the control group. With regard to the nutrients intakes, the case subjects consumed significantly higher amounts of nutrients such as protein, calcium, sodium, phosphorus and niacin than the control group. The case group showed a tendency to consume higher amount of protein, fat, calcium and iron from animal food sources. In the present study dietary factors which were suspected as being risk factors for stomach cancer included high consumption of animal foods, specific nutrients such as protein, sodium and niacin, specific food groups such as meat, spices, and low consumption of fruits and mushrooms. Therefore, it is recommended that more extensive and systematic surveys be conducted to confirm the risk factors for stomach cancer, taking into consideration the dietary cultural characteristics of this region.

This study was carried out to survey the eating behaviors and the food preferences of the tourism transportation business managers in Daegu areas by age. The survey was performed from 17 to August 25, 2003 by questionnaires and the subjects were 365 males. As a general factor, the subjects of survey were male drivers in their thirties to sixties. Their education level was middle school(44.9%) and high school(45.8%) diploma. This study showed that the managers eat three meals per day with high percentage(75.9%) and a large number of managers(24.1%) eat two meals only. 77.8% of the subjects responded that their diet life were irregular due to the property of their job. Frequency of eating-out turned out to be much higher in managers aged 60 over(p<0.001). They considered taste of the food firstly, and the prices of the food secondly, but the nutritional value of the food was considered with a low percentage(22.7%). We found that their BMI were overweight from 23.5 to 26.01, their calorie and some nutrient intakes were below their RDA. The most insufficiently consumed nutrient(less than 75% of RDA) was vitamin B₂ followed by calcium. The food preferences of subjects showed that the managers preferred boiled rice to any other rice as a staple foods. Their favorite menu of one-course Korean style meal turned out to be the bibimbob(boiled rice mixed with assorted vegetable and meat). As for subsidiary foods, out of all various meat soups, beef soups and beef-rib soups were most preferred. The most preferred stew were soybean paste stew and kimchi stew, and the most preferred cooked vegetables were cooked spinach, seasoned cucumber. Baechu kimchi(white cabbage kimchi) were the most preferred kind of kimchi. For desserts there was a very high preference for the watermelons, apples, and pears. For beverages the most preferred were ginseng tea, fruit juices and dietary fiber drinks. From the results listed above, the nutritional education needed to be done to the tourism transportation business managers to set the proper menu considering the characteristics of the preference each age group of managers.

Numerous studies have investigated quantifying dietary intake according to the weight status of children and adolescents. However, studies on differences in quality among diets remain scarce. This study compared diet quality by weight status and examined correlations between quality of diet and obesity in children and adolescents. Two hundred fourteen children and adolescents aged between 9 and 18 years participated in this study (Normal weight n=104, Obesity n=110). The data related to food intake were investigated by dietary records, Diet Quality Index-International (DQI-I), and Nutrition Quotient (NQ) and then compared with Dietary Reference Intakes for Korean (KDRIs). In DQI-I, moderation factor (control of unhealthy foods) score was 21.7 in the normal weight group and 19.5 in the obesity group. The normal weight group showed a higher score for moderation factor than the obesity group (P<0.001). Compared with KDRIs, vitamin $B_6$, folate, vitamin C, vitamin E, calcium, potassium, and zinc intakes were insufficient in both groups. Multiple logistic regression analysis revealed that DQI-I moderation was negatively associated with obesity (OR=0.77, 95% CI 0.69-0.87) after adjustment for age, gender, income, and total energy intake. Our results suggest that children and adolescents require nutritional education to understand the importance of vitamin and mineral consumption. Especially, education for children and adolescents with obesity needs to emphasize moderation of nutrient intake that can cause diseases with hyper-ingestion such as sodium and high calorie-low nutrition foods.

The objective was to evaluate the factors influencing on the growth of children aged 3 - 6 years by mini dietary assessment and anthropometric indices in 556 children and by analyzing mineral contents of hair from 273 children by inductively coupled plasma mass spectrometry (ICP-MS). The mean concentration of zinc (Zn) in hair was 68.9 $\pm$ 31.1 ppm and the zinc level of 91 ％ children was less than 60％ of the reference value of 180 ppm. The mean content of lead (Pb) in hair was 1.76 $\pm$ 1.20 ppm, but only 67％ of 273 children was within the reference value of 2 ppm and the lead level of 33％ of children was 2 - 4 times higher than the reference value. The level of Zn was negatively correlated with Pb content (r = -0.305, p 〈 0.01). Hair Zn content, regardless of age, was significantly positively correlated with height (r = 0.214) and body weight (r = 0.159). The height of 95.3％ children was belonged to the normal range of 90 - 109.9％ of standard value and the body weight of 49.8％ children was in the range of 90 - 109.9％ of standard value. However, 8.1 ％ children was overweighted (110 - 119.9％ of standard) and 9.4％ children was obese (120 - 149.9％ of standard) and 0.9％ children was severe obese (〉 150％) which resulted in total 10.3％ obese. Contrary to our expectation, 32.8％ children was underweight (70 - 89.9％ of standard) and 36％ of the underweight children showed the low content of zinc (10 - 49 ppm) in hair. There was no significant correlation between dietary intake of Zn and hair Zn content. Hair Zn content was low even though children consumed greater than 75％ of their requirement for zinc. Regardless of dietary intake of Zn, hair Zn level was rather negatively correlated to the content of Pb in hair. 38.8％ children had an unbalanced diet which resulted in lower intake of calorie, Ca, Zn, vitamin B$_2$ compared with those consuming variety of foods. Therefore, it would be needed that new approach for nutrition education to improve eating habit having the unbalanced diet in preschool children. It might be also suggested to develop new food products to complement the nutrients of Zn, Ca, Fe as snacks or dietary supplement for Korean preschool children.
