This study was performed to investigate the food habits and nutrient intakes of middle aged adults who are living in DoBong-Gu, Seoul. Two hundred thirty eight middle aged adults from 20 to 64 years of ages were recruited for survey. Mean of age were 40.8years for male, 45.2 for female, respectively. Subjects were interviewed for general characteristics, food habits, health status, physical activity and nutrients intakes which is using 3 day recall method by a trained interviewer. Anthropometric data showed that mean height and weight were 171.9cm and 71.9kg for males and 158.6cm and 56.9kg in females, respectively. Mean BMI for males and females were 24.3 and 22.6kg/m², respectively and the subjects with BMI 25-30kg/m² were 36.1 and 15.5%, respectively. One hundred twenty four subjects(52.8%) answered they were soso in perception of health status. 63% of subjects ate meals 3 times a day. It was found that 119 subjects were skipping the breakfast due to mainly the lack of time, no appetite and habits in order. 43.5% of subjects answered they had regularity of meal times. About 71.7% of subjects were smoking. And 76.8% of males and 35.4% of females answered they had drinking habits. About 66.6% of subjects responded that they were exercising regularly. The most of do the excercise was walking for subjects. Sixty percent of subjects responded that they had no experiences of weight control. 46.8% of subjects answered that their own body shapes are unsatisfied. Although the mean energy intake of the subjects did not reach the recommended dietary allowance( RDA), mean protein intake was well above the RDA for both sex groups(102.1% formall and 117.6%, for female respectively). Intakes of energy, Ca, vitamin B2 and Zn in males and Zn only in females were below 75% of RDA The results suggest that there should be effective nutrition education programs for middle aged adults to improve the food intake and correct their eating habits to enhance their general health in nutritional aspect. The improvement in the nutritional status of middle aged adults is even more important because that could lead into the better health the elderly.

This study was designed to observe the effect of green tea on lipid metabolism in rats treated with 1,2 dimethylhydrazine (DMH) and fed high fat diets. Male Sprague Dawley rats, at 7 weeks of age, were divided into two groups according to supply of green tea: control and green tea. The green tea group received only 2.5% (w/v) of green tea throughout this experiment. Experimental diets containing 30% fat (15% w/v) of total calories provided for 2 groups. The rats were injected intramuscularly with 1,2-dimethylhydrazine at 15㎎/㎏ body weight twice a week for 6 weeks to total dose of 180㎎/㎏ BW. Autopsy on the 20th week showed that tumor incidence in green tea group was lower than that of control by 39, 47%. Also, total number of tumor and average tumors had the same trends. The plasma total cholesterol level in green tea rats tended to be lower than that of control. There was no difference in HDL-cholesterol level. The green tea group had slightly increased in triglyceride level in the control rats. But not to a statistically significant degree. The lipogenic enzymes activity were not significantly changed by green tea. The results showed that green tea has a preventive effect in colon carcinogenesis and but that green tea does not affect a hypolipidemic effect in rats treated with 1,2-dimethylhydrazine and high fat diets.

본 연구는 4주령 ICR 수컷 마우스에 대두유와 쇠기름에 1% CLA를 첨가한 식이로 4주 동안 사육하여 체중,체지방량,혈장과 간의 중성지방 농도,SCD1의 유전자 발현과 간에서의 지방산 조성을 관찰하여 얻은 결과는,대두유와 쇠기름에 첨가한 CLA는 체중과 식이이용효율에는 영향을 미치지 않았으나 부고환지방 조직과 혈장에서의 중성지방 농도를 유의적으로 감소시켰다. SCD1 의 발현과 △9 desaturase index는 기름의 종류나 CLA의 첨가에 따라 차이가 없었다. 결론적으로 CLA는 기름의 종류에 상관없이 지방조직 (adipose depots) 감소 효과가 있었으나 지방조직 감소는 SCD1 유전자 발현과 △ 9 desaturase index와는 독립적인 것으로 나타났으며 SCD1 유전자 발현은 기름의 종류에 의존적이지 않았다. This study investigated the effects of conjugated linoleic acid(CLA) on the fat deposition, triglyceride level and the expression of stearoyl CoA desaturase l(SCDI) in the livers of male ICR mice that were fed with either soybean oil or beef tallow supplemented with CLA. Mice weighing 25-30g were divided into four groups, soybean oil(SBO), and SBO supplemented with 1% CLA(SBOC), beef tallow(BT) and BT supplemented with 1% CLA(BTC). Each group consisted of 10 mice and they were fed with the experimental diets for 4 weeks. The experimental diets were composed of 64% carbohydrates, 20% proteins and 16% fat in terms of their contributions to total calories, and other nutrients were identical. The measurement of triglyceride was done by using a kit. Fatty acid compositions were analyzed in the liver using gas chromatography. The levels of SCD1 expression was analyzed by RT PCR in the liver. No significant difference was found in the levels of food intake, body weight and food efficiency among experimental groups. However, the weights of epididymal fat pads and the level of triglyceride in the plasma were significantly lower in the SBOC and BTC(p<0.05) compared to SBO and BT group. The expression level of SCDl gene and △9 desaturase index were not significantly different regardless of fat used and CLA supplemented. Taken these results, addition of 1% CLA showed decreasing effects on the fat depots weight and the concentration of triglyceride. The SCD 1 gene expression and △9 desaturase index were not influenced by the types of fat used in the aspects of CLA effects.

This study investigates the perceptions and preferences of university students for Korean traditional tea. The data were analyzed with frequency, percentage, t-test and ANOVA using the SAS/PC package system. The results were as follows; Responents' interest in Korean traditional teas was low. 81.7% of the students answered that they perferred western tea because they are convenient to drink than Korean traditional tea. And also the students said they were not used to drink Korean traditional teas. The more awareness of Korean traditional tea the students had, the higher their preference for them. The most often named traditional tea were Ginseng tea, Sikhae, and green tea in that order. The most preferred traditional tea were Sikhae, green tea and a citron tea (YuJa tea) in that order. Most of the students responded that they might like Korean traditional tea more if the taste were improved and the cooking preparation was easier. In general, they were satisfied with korean commercial traditional tea. But, they pointed out that Korean commercial traditional tea should have more variety, better taste and better quality. This study suggests that Korean traditional tea would be more popular if a wider variety and better quality of taste werw available. The study also points out a need to publicisize these teas. The study implies that homes, schoools and communities should be concerned about Korean traditional teas, so they will become a part of Korean cultural eating patterns.

강금지 한국조리과학회 2001 한국식품조리과학회지 Vol.17 No.1

본 연구에서는 자취 형식의 기숙사에 살고 있는 여대생들의 건강과 관련된 식행동과 영양소 섭취 실태를 알아보고 이들을 BMI에 따라 저체중군과 정상체중군으로 나누어 비교한 결과를 요약하면 다음과 같다. 1. 평균 연령은 18-20세가 66.3%, 21-25세 33.1%, 26-27세 0.6%순이었다. 한달 평균 용돈은 20-30만원 41.4%, 30-40만원 34.3%, 40만뭔 이상 14.6%, 20만원이하가 8.4%였다. 평균 식비는 10-15만원 42.2%, 15-20만원 27.9%였다. 건강상의 문제는 없다 77.3%, 변비 33.9%, 소화불량 32.6%, 빈혈 21.4%, 위장질환 13.2% 순이었다. 2. 평균 신장은 162.37±4.36㎝ 평균 체중은 52.48±5.54㎏, BMI 19.89±1.89이었다. 저체중군(BMI 20이하)은 53.1%로, 평균신장 162.61土4.19, 체중 48.99土3.60㎏, BMI는 18.51±0.98이었다. 정상체중군(BMI 20-25이하)은 46.9%로, 평균 신장 162.37±4.36㎝, 체중 58.43±4.63㎏, BMI는 21.46±1.38이었다. 3. 건강에 대한 자가 인식은 BMI에 상관없이 대부분이 보통 이상(76.4%)으로 대답하였다. 저체중군(28.7%)이 정상체중군(17.9%) 보다 건강이 좋지 않다고 생각하였다(p<0.05). 자기 체형에 대한 이미지는 저체중군의 63.4%가 "보통 체형"이라고 생각하였고, 정상체중군 에서는 73.1%가 "살찐 편"이라고 생각하였다(p<0.001). 체중조절의 경험은 정상체중군이 유의성있게 많았다(p<0.001). 체중조절에 사용된 방법은 음식 덜 먹기, 운동, 한 끼 굶기, 간식 안 먹기 순이었다. 운동은 거의 하지 않았으며, 음주 횟수는 한달에 1-2회가 가장 많았고(45.5%), 흡연은 "안 한다"가 95.1%였다. 영양제는 저체중군이 정상체중군보다 더 많이 복용하였다(p<0.05) 4. 81.4%가 불규칙한 식사를 하고, 거르는 끼니는 아침이 89.6%로 가장 많았고. 거르는 이유는 시간이 없어서(75.4%), 먹을 것이 마땅치 않아서(28.3%) 순이었다. 간식섭취는 하루 2번이 가장 많았고, 저체중군이 정상체중군 보다 '간식을 거의 먹지 않는다"라고 대답한 학생이 유의적으로 많았다(p<0.05). 좋아하는 간식은 두 군 다 과자, 과일류 순이었다. 정상체중군이 저체중군보다 빵과 케일을 더 많이 먹었다(p<0.05). 나쁜 식습관으로는 불규칙한 식사(60.5%), 과식(39.2%)순이었다. 정상체중군이 저체중군보다 맵고 짠것을 더 먹는 것으로 나타났고(p<0.05), 저체중군이 편식을 더 많이 하였다(p<0.01). 5. 외식시 맛과 가격을 우선적으로 고려하였고, 하루에 한번 이상은 외식을 하며, 외식장소는 분식점과 학교 식당이며, 선택하는 음식은 한식, 일품요리, 분식순이었다. Fast food 이용 횟수는" 거의 가지 않는다"가 가장 많았고, 일주일에 3-4번 순이었다. 정상체중군이 저체중군보다 이용횟수가 많았다 (p<0.05). 6. 식품을 주로 구입하는 곳은 동네 슈퍼와 대형 슈퍼였고, 밥은 적어도 하루에 한번은 하고, 반찬은 주로 집에서 부쳐오는 반찬을 먹고 있으며, 하는 요리의 종류는 찌개, 국 순이었다. 7. 우유와 유제품군에서는 우유를 가장 자주 마시고 있으며, 아이스크림, 요구르트 순이었다. 육류군은 계란, 두부와 햄과 소세지의 순으로 자주 먹었으며, 정상체중군이 저체중군보다 소고기, 돼지고기, 닭고기,햄과 소세지를 덜 자주 먹었다(p<0.05). 곡류는 밥은 하루에 한번은 먹으며, 채소는 김치는 하루에 한 번씩은 먹으나, 담색, 황색, 녹색채소의 섭취 횟수는 낮았다. 과일은 일주일에 1-2회 이상 먹었으며, Fast food중에서는 햄버거를 가장 자주 먹으며, 음료는 커피를 가장 많이 마셨다. 8. BMI에 따른 열량과 영양소에는 차이가 없었다. 평균 열량은 1575.3Kcal로 권장량의 78.7%이었고, 단백질은 권장량의 124.7%, 비타민 A 101.0%, 비타민 B_1 131.0%, 비타민 B_2 82.3%, 나이아신 89.7%, 비타민 C 78.1%, 철분은 80.2%이었다. 칼슘은 권장량의 57.0%로 가장 낮았다. 이상의 결과로 여대생은 체중 과다보다는 저체중의 비율이 높았는데 이들이 가임 연령층이라는 것을 고려하여 본 다면 이에 대한 식생활 대책이 필요하다. 기숙사의 여대생의 건강과 관련된 행동, 식행동과 영양소 섭취는 집에서 있는 여대생과 비교하여 불규칙한 식사의 비율이 높았고, 아침 결식율도 높으며, 채소와 과일의 섭취 빈도가 낮음을 알 수 있었다. BMI에 따라서는, 저체중과 정상체중의 여학생 간에는 식행동과 영양소 섭취에 큰 차이가 없음을 알 수 있었다. 기숙사생들이 바른 식습관을 가지기 위하여 기숙사 자체와 학교의 영양교육을 통하여 간편한 아침식사, 간단히 할 수 있는 요리 등을 강좌를 통하여 가르치고, 학생들이 가장 많이 이용하는 학교식당이 식단의 다양함과 질을 높일 수 있도록 식단 개발이 필요하다고 생각된다. This study was to investigate the behavior related to health, food habits, food consumption pattern and nutrient intakes of female students who residing in dormitory(self cooking) according to BMI(Body Mass Index). This study was carried out by questionnaired on June, 2000. Three hundred nine students were answered. The results were as follows: The means of height, weight and BMI were 162.37±4.36㎝, 52.48±5.54㎏ and 19.89±1.89. Under 20 of BMI among students were 53.1% and 20-25 of BMl were 46.9% of students. In the self recognition of body shape, 63.4% of under weight subjects answered that their weight were normal. 73.1% of normal weight regard themselves more obese than their actual body shape normally shows. 51.2% of under weight subjects had attempted to control their weight. This resu1ts suggest that their weight control attempts were unnecessary. 81.4% of subjects were answered irregular meals regardless BMI. 89.6% of subject skipped breakfast. The main reasons were due to lack of time or not to eat proper food. Under weight subjects had less snack than normal weight subjects did(p<0.05). Normal weight subjects had more bun and cake than under weight subjects(p<0.05). The consumption of vegetables and fruits were low regardless BMI. Mean energy, protein, Fe, Vit A. B_1, B_2, niacin, Vit C were above 75% of RDA, except calcium, in subjects. This study suggest that a comprehensive nutrition education program is need for college student in dormitory to impove their eating habits about skipping meal and breakfast and to increase the consumption of vegetables and fruits.

본 연구는 식사조절, 운동. 행동수정요법을 중심으로 한 체중 조절 프로그램에서 영양교육의 효과를 보기 위해서 수행되어졌다. 8주 동안 진행된 이 프로그램의 교육내용으로는 저칼로리 영양에 대한지식, 운동, 식습관 교정, 적절한 체중을 유지하는 방법과 비만을 예방하기 위한 전략 등이었다. 7명의 덕성여대생이 프로그램에 참가하였다. 모든 참가자는 8주 동안 1㎏에서 4.5㎏까지 감량을 하였고, 감량된 체중을 3개월 후까지도 유지하였다. 8주 동안 Body Mass Index(BMI)는 유의적인 수준으로 감소(p<0.05)되었다. Triglyceride는 낮아지는 경향을 보였으나 total-cholesterol과 HDL-cholesterol은 변화하지 않았다. 프로그램 진행 동안 영양지식은 변화하지 않았으나 식습관은 유의적으로 증진이 되었다(p<0.05). 변화된 식습관은 3개월 후 까지도 지속되었다. 본 연구의 결과는 과학적인 체중조절 프로그램에서 영양교육을 실시함으로써 안전한 체중감량과 식습관을 개선할 수 있도록 함을 보여주었다. This study attempted to evaluate the effectiveness of nutrition education on the multidisciplinary weight management program. The major components of this weight control program, held for 8 weekly sessions, were the nutrition information about a low calorie diet, the way to increase physical activity, an awareness of eating habits and the strategies for the maintenance of Proper body weight and other information related to prevent obesity. Seven students of DukSung Women's University participated in this Program. All of Participants lost (from 1㎏ to 4.5㎏) of body weight at the end of the weight control program. The reduced body weight of participants was maintained for the three-month follow-up period During the weight control period, body mass index(BMI) significantly decreased (p<0.05), whereas the level of total cholesterol and HDL-cholesterol did not. Nutrition knowledge scores did not change, however, their eating habits were significantly improved after the 8-week session (p<0.05) . The changed eating habits maintained for the three-month follow-up period. The results of this study suggest that the weight control program should be based on well-planned nutrition education in order to maintain the reduced body weight and changed eating habits.
