본 연구에서는 현재 시중에서 많이 판매되고 있는 불포화 지방산의 함량이 높은 오일(올리브 오일, 아마씨유 및 들기름)의 mice 내 대사에 미치는 목초액의 영향을 알아보기 위해 실시하였다. 오일과 목초액의 첨가에 따른 각 군의 평균 체중은 27~31 g 사이였으며, 평균 체중에는 유의한 차이가 나타나지 않았다. 콜레스테롤 수치는 목초액을 첨가한 PP군은 96.71±25.75 ㎎/㎗로 나타나, 올리브 오일을 첨가한 COW군(133.56±21.53 ㎎/㎗)에 비해 유의하게 낮게 조사되었다. 오일을 첨가한 여섯 군을 비교해 보면, 콜레스테롤 농도는 CFP군에서 100.30±22.60 ㎎/㎗로 가장 낮게 나타났으며, 그 다음으로 CPP군에서 110.70±11.16 ㎎/㎗, CFW군에서 121.90±23.85 ㎎/㎗ 순으로 조사되었다(p<0.05). 중성지방 농도는 COP군이 121.10±50.79 ㎎/㎗인 반면에 CFP군과 CPP군에서 각각 77.80±38.58㎎/㎗와 92.40±33.04 ㎎/㎗로 유의하게 낮았다(p<0.05). 식이중 올리브 오일의 첨가는 PW군에 비해 콜레스테롤과 LDLcholesterol의 수준 증가시켰다. 그러나 식이 중 아마씨유와 목초액의 동시 첨가는 PW군에 비해 HDL-cholesterol의 수준은 증가시킨 반면에, LDL-cholesterol과 중성지방의 농도는 감소시킨 것으로 조사되었다. 또한 식이 중 들기름의 첨가는 중성지방 농도를 감소시켰으며, HDL-cholesterol의 수준을 증가 시켰다. 결론적으로 식이를 통한 아마씨유나 들기름의 섭취는 지질대사에 영향을 주는 것으로 사료된다. 특히 아마씨유와 목초액을 동시에 첨가한 군에서는 HDL-cholesterol의 수준은 증가시킨 반면에, LDL-cholesterol과 중성지방의 농도는 감소시킨 것으로 조사되었다. 따라서 오일과 목초액의 적당한 양의 장기간 투여는 콜레스테롤, LDL-cholesterol 및 중성지방을 효과적으로 억제할 뿐만 아니라, HDL-cholesterol 수준을 효과적으로 증가시킬 수 있을 것으로 사료된다. 이에 본 연구를 기초로 해서 불포화지방산의 함량이 높은 오일과 목초액의 상관관계에 대한 항산화 연구 등이 지속적으로 수행되어야 할 것으로 사료된다. Our objectives in this experiment were to study the effects of oils that are high in contents of unsaturated fatty acids (olive, flaxseed, and perilla oils) and pyroligneous liquor on plasma lipid concentrations in mice. Male ICR-mouse (n=10 per group) were fed powdered form diets containing oil and pyroligneous liquor for 60 days. The cholesterol level of the PP group (96.71±25.75 ㎎/㎗) was lower than that of the COW group (133.56±21.53 ㎎/㎗). Levels of triglyceride of COP, CFP, and CPP groups were 121.10±50.79 ㎎/㎗, 77.80±38.58 ㎎/㎗, and 92.40±33.04 ㎎/㎗, respectively (p<0.05). The dietary addition of olive oil increased the plasma lsevels of cholesterol and LDL-cholesterol. On the other hand, the dietary addition of flaxseed oil and pyroligneous liquor increased the plasma level of HDL-cholesterol and decreased the plasma levels of LDL-cholesterol and triglyceride compared with those of the control group. Further, the dietary addition of perilla oil decreased plasma triglyceride but increased HDL-cholesterol. The decrease in the cholesterol level was much higher in the CFP group. In conclusion, the dietary addition of long-term pyroligneous liquor effectively decreased the plasma levels of cholesterol and triglyceride and increased the plasma level of HDL-cholesterol. The additional dietary administration of flaxseed and perilla oils increased the effect of pyroligneous liquor.

본 연구는 삼육대학교에 재학 중인 20∼24세의 여대생 253명을 대상으로 전공에 따라 일반(인문계 및 이공계) 전공자(77명), 식품영양학 전공자(103명) 및 체육학 전공자(73명)로 분류하여 이들의 식습관, 영양소섭취상태, 건강습관 및 신체계측 조사를 통하여 차이점을 분석하였다. 전체 여대생들이 한 달 동안 쓰는 용돈으로는 20∼30만원이 가장 많았다. 여대생들의 평균 신장은 162.3±4.7 ㎝, 평균 체중은 52.2±5.1 ㎏이었으며, 평균 체질량지수는 19.8±1.8 ㎏/㎡로 조사되었다. 전체 여대생들의 평소 식사시간의 규칙성을 보면, 17.8%만이 규칙적이라고 답한 반면에, 29.3%는 평소의 식사시간이 불규칙적이라고 답하였다. 여대생들의 30.0%가 아침식사를 하는 것으로 조사되었고, 조사대상자의 13.1%는 아침식사를 전혀 하지 않는 것으로 조사되었으며, 여대생들이 아침식사를 하지 않는 이유로는 〈아침시간이 바빠서〉라고 답한 응답자가 55.6%를 차지하였다. 전체 여대생 중 과식을 하지 않는 여대생은 17.0%였고, 과식을 자주하는 여대생은 14.6%로 조사되었으며, 과식을 하는 이유로는 60.0%가 〈좋아하는 음식이 많아서〉라고 답하였다. 전체 조사대상자의 외식을 자주하는 비율은 43.0%나 되었고, 외식을 할 때 선호하는 음식의 종류로는 세 군 모두 한국음식이 55.2%로 가장 높았다. 전체 여대생의 91.2%는 편식을 하는 것으로 조사되었으며, 편식을 하는 이유로는 65.6%가 〈그냥 아무 이유 없이〉라고 답하였다. 간식을 전혀 하지 않는 여대생은 12.0%로 조사되었으며, 본 연구에서 간식을 1∼2회 한다는 여대생은 76.9%로 조사되었다. 전체 조사대상자의 영양소의 섭취 실태는 엽산을 제외한 모든 영양소를 과잉 섭취하는 것으로 조사되었다. 여대생의 48.8%가 운동을 한다고 답하였으며, 일주일 동안의 운동 횟수는 일주일에 1∼2번 하는 경우(40.2%)가 가장 많았다. 영양제 복용 여부를 묻는 질문에 전체 조사대상자의 25.4%가 영양제를 복용하는 것으로 조사되었으며, 복용하는 영양제의 종류로는 세 군 모두 비타민 제제를 가장 많이 섭취하고 있었다. 일반(인문계 및 이공계) 전공자의 53.2%는 한 달 동안 쓰는 용돈으로는 20∼30만원이라고 답하였다. 일반(인문계 및 이공계) 전공자의 22.1%는 평소에 식사시간이 규칙적이라고 답하였으며, 28.6%는 매일 아침식사를 한다고 답하였다. 일반(인문계 및 이공계) 전공자의 경우 특히 다른 두 군에 비해 과식, 외식 및 편식을 하지 않는 비율이 높게 조사되었다. 간식의 경우 일반(인문계 및 이공계) 전공자의 경우 과일을 섭취(26.1%)하는 비율은 낮았으며, 영양소 섭취 중 나트륨의 섭취량이 높은 것으로 조사되었다. 식품영양학 전공자의 16.5%는 평소에 식사시간이 규칙적이라고 답하였으며, 아침식사를 매일 한다고 답한 비율도 30.1%였다. 식품영양학 전공자는 간식으로 다양한 식품을 섭취하고 있었으며, 섭취하는 영양소로는 vitamin C와 vitamin E의 섭취량이 높게 조사되었다. 또한 복용하는 영양제 중 비타민 제제(70.8%)를 다른 두 군에 비해 가장 많이 섭취하는 조사되었다. 체육전공자는 방과 후에 각종 운동시설에서 시간제로 아르바이트를 하는 것으로 조사되었으며, 다른 두 군에 비해 용돈으로 사용되는 비용이 많은 것으로 조사되었다. 신체계측 결과 체육전공자는 전체 여대생의 평균 신장에 비해 2.0 ㎝ 더 크게 조사되었다. 체육전공자는 식사시간이 불규칙적이었으나, 31.5%는 매일 아침식사를 한다고 답하여 다른 군에 비해 아침을 잘 챙겨 먹는 것으로 조사되었다. 또한 과식과 편식을 하지 않는 비율이 높은 편이었으며, 간식 섭취에 있어서 체육전공자는 패스트푸드 및 튀김류의 섭취가 낮은 편이었으나, 우유 및 유제품의 섭취는 높은 편이었다. 영양소 섭취 실태를 보면, 열량, 지방, vitamin A, B₁, B₂, B?, 나이아신, 철, 인 및 콜레스테롤의 섭취가 높은 것으로 조사되었다. 체육을 전공하는 여대생은 94.5%가 운동을 하는 것으로 조사되어 다른 두 군에 비해 운동량이 많았다. 따라서 본 연구 결과에서도 여전히 전체 여대생들의 식생활 문제점으로는 이미 선행연구에서 제시했다시피 식사시간의 불규칙성, 아침 식사의 결식, 과식과 편식하는 습관, 가공식품과 패스트푸드 위주의 간식 섭취 및 영양소의 불균형적인 섭취가 문제시되었다. 이를 해결하기 위해서는 실생활에서 쉽게 이용할 수 있는 체계적인 영양교육의 실시가 시급하며, 식품영양학 수업자체가 이론적인 지식에서만 끝나는 것이 아니라 누구든지 자신의 건강을 유지하기 위해 식생활을 잘 실천할 수 있도록 지도하여야 할 것이다. 또한 이상의 모든 결과를 종합하여 판단할 때, 식품영양학을 전공한 여대생들이 다른 군에 비해 식습관과 영양상태 및 건강습관이 우수하다고 볼 수는 없었다. 즉, 식품영양학을 전공한 여대생의 경우 전공시간에 배운 여러 가지 영양교육 및 영양지식 등을 실생활과 접목시켜 활용하는데 있어서 부족한 점이 많은 것으로 조사되었다. 오히려 체육을 전공하는 여대생들은 영양소를 과잉 섭취하였지만, 그만큼 운동을 통해 에너지를 소비하는 것으로 조사되었다. 일반(인문계 및 이공계) 및 체육학 전공자들이 쉽게 접할 수 있는 다양한 영양교육 프로그램의 개발이 요구되며, 학교 내에 식품영양학 수업의 개설을 통해 누구나 식품영양학 수업을 들을 수 있는 좀 더 많은 기회가 제공되어져야 할 것으로 사료된다. This study was conducted to compare the dietary habits, nutrient intake and health status of female college students at Sahmyook University according to their majors. Specifically, women majoring in literature and science (77), food and nutrition (103) and sport (73) were evaluated. College women in the sports department were more likely to have a part-time job and had greater expenses than women in the other departments. The average height of college women in the sports department (164.3±4.6 ㎝) was 2.04 ㎝ taller than that of women with other majors (162.3±4.7 ㎝). College women in the department of literature and science were more likely to have an unbalanced diet, even though they commonly ate small amounts of fruit as snacks. They were more prone to take nutrient tablets and vitamins when compared to women in the other departments. College women in the department of sport were more likely to have unbalanced meals (31.5%) and to overeat. Students in the department of food and nutrition ate more fruit, vitamin C and E but less cholesterol containing foods (p<0.05), less fast food and fried food than students in the other departments. The subjects in the department of sport ate less bread, sweet potatoes, fast foods and fried foods but more calories, fat, vitamin A, vitamin B, niacin, Ca, P and cholesterol than students in the other departments (p<0.05). They were also more likely to exercise for more than two hours a day. The most common problems among college women were going without meals, eating an unbalanced diet, overeating, intake of ill-balanced nutrients and lack of exercise. It was found that college women in the department of sport had a better intake of nutrients and maintained healthier life styles.

This study is conducted to compare the problems affecting dietary habits and health status between a long-term exercise group and non-exercise group of males older than 50 years. Most subjects of the two groups consider regular exercise to be the most important factor for maintaining health, and recognize hypertension as the number one concern. The most common nutritional supplement among subjects is multiple vitamins, and sleeping time range from 6~8 hours. Breakfast fasting rate was 15.9% among non-exercise group (NEG), where overeating and eating out rates were higher among exercise group (EG) when comparing to NEG. Fasting rates of breakfast, and consumption rates of milk and dairy products, vegetables such as kimchi, and fruits and fruit juices are higher among the EG. Overeating and eating out rates are lower among NEG, whereas eating rates of proteins like meat, fish, eggs, beans, fried foods, high-fat meats carbonated drinks, ice cream, and salt intakes are higher. Rates of health, dietary habits, and nutrient intakes are higher among EG. Energy intakes among the two groups were below the standard level, Vitamin B2 intake is low in EG, and folic acid and calcium intakes were higher in NEG. The exercising group care more about health, eating habits and nutrient intakes, and low smoking rates are being observed. Thus, specific dietary improvement programs for adult men, are required, and it is necessary to consider the practice of nutrition education.

This study focused on the nutrition knowledge, food purchase behaviors, and dietary habits of 213 housewives (41 women under 39 years, 98 women 40~49 years, and 74 women over 50 years). Younger housewives held more special jobs, whereas older housewives worked as housewives or had no jobs (p<0.05). The average monthly income of the three family groups was 3,000,000~5,000,000 won, and the monthly dietary expenditure for all three groups was 200,000~500,000 won. Familial frames for the three groups was nuclear family (over 80%), but housewives younger than 39 years (19.5%) lived together with their parents and let them take care of their children. Housewives (over 50 years) prepared a balanced diet for every meal, utilized less drastic cooking methods to prevent loss of nutrients, and shopped at many places in order to save money on various food materials. Further, they purchased food materials that resulted in the least amount of left overs. On the other hand, housewives under 39 years visited large supermarkets and purchased cooked foods more than other groups. Housewives under 39 years considered nutrients content as the most important factor when purchasing food materials, whereas 74.5% of housewives between 40~49 years and 51.4% of housewives over 50 years put the most importance on flavor (p<0.05). Housewives under 39 years were interested in manufacture date, nutrient content, and food price, in decreasing order, whereas housewives between 40~49 years and over 50 years were interested in manufacture date, food prices, and nutrient content. Older housewives were interested in brown rice and fruits, whereas younger housewives under 39 years were interested in meat, fish, eggs, fried foods, and fast food. Older housewives over 50 years did not consume fried foods more than two times per week and consumed three regular meals more often than younger housewives. Accordingly, for younger housewives, it is necessary that healthy foods be cooked for their families.

Korea used to be a country where individuals ate diets high in vegetables and rice, but in recent years, it has become a country where western-style diets are increasingly popular. Consequently, the age for chronicle disease, including obesity and diabetes, has become lower. The purpose of this study was to compare the dietary habits of kindergarten children between lacto-ovo vegetarian and non-vegetarian families. The data were collected from the children(n=300) at Sahmyook University Kindergarten. The results showed that non-vegetarians had higher intakes of cookies, cakes, processed foods, ice cream, and fast foods, while vegetarian children consumed high amounts of vegetables, fruits, and kimchi. The non-vegetarian children tended to have irregular meals, and ate high-fat meats such as kalbi and samgyupsal. However, the results show it is important that many children among both vegetarian and non-vegetarian families should be encouraged to have appropriate essential nutrients, because a high percentage of children in both groups appeared to have low intakes of energy, vitamin $B_2$, vitamin C, calcium, zinc, iron, etc.

The principal objective of this study was to supply basic material determine basic information regarding effective health promotion regimens for elderly women via a comparative survey of health status by aging age between elderly women (=70 y) and college women. The subject groups of elderly women (=70 y) and college women were selected and surveyed from March to October, 2008, in the Seoul area. The average age of the elderly women assessed in this study was 78.64±7.30, the average height was 147.07±5.72 ㎝, and the average weight was 50.47±7.44 ㎏. As compared with college women, a higher percentage of elderly women ate breakfast regularly, but the elderly women also experienced difficulties in chewing due to dentures, and therefore ate their meals with large quantities of liquids, and usually ate their meals within 10 minutes. The majority of elderly women suffered from at least one disease, and the most common symptom reported was hypertension (25%). 52.2% of elderly women and 47.8% of college women reported that they exercised 1~2 times per week. They reported that their favorite exercise was light exercise, such as jogging and athletics (73.1%). As compared with college women, the smoking rate was lower among elderly women, but some of the elderly women were long-time smokers or alcoholics. The differences in red blood cells counts, Hb, hematocrit, and MCV of the between elderly women and college women were significant. In addition, but the MCH and MCHC were higher in elderly women compared with college women and the total cholesterol of elderly woman (175.62±38.89 ㎎/dL) was significantly lower compared with college woman (186.13±28.19 ㎎/dL). TG (127.89±51.25 ㎎/dL) and LDL-cholesterol (120.51±32.88 ㎎/dL) of elderly woman were significantly higher than TG (79.71±40.9 6㎎/dL) and LDL-cholesterol(103.78±22.94 ㎎/dL) of college woman (p<0.05). The levels of HDL-cholesterol (58.78±12.90 ㎎/dL) in the college women was significantly higher than the HDLcholesterol levels (48.17±13.79 ㎎/dL) of the elderly women (p<0.05). Serum vitamin C levels in elderly women were significantly higher than those of college women (p<0.05), whereas no significant difference was detected between the two groups. Consequently, it can be concluded that the appropriate education programs for dietary habits and health promotion are necessary for a healthier life. Additionally, it is necessary for individuals to precisely determine precisely their own health status, and develop appropriate dietary programs for themselves.

식품영양학 전공 및 비전공 여대생의 식습관 및 건강관심도에 관한 비교 연구

신경옥(Kyung Ok Shin),정근희(Keun Hee Chung) 동아시아식생활학회 2010 동아시아식생활학회지 Vol.20 No.3

The dietary habits of 156 female college students in the Department of Food and Nutrition (n=79) and other departments (n=77) at Sahmyook University, Nowon-gu, Seoul were evaluated from September to December, 2009. All participants completed a questionnaire designed to determine the mini dietary assessment score, as well as to evaluate nutrient intake, healthrelated questions and to determine a physical score. The students in the department of food and nutrition tended to consume more vegetables than Kimchi for each meal (39.2%), fried foods twice a week (38.0%) (p<0.05) and less fruits and fruit juices (29.1%). In addition, 15.2% of students ate Samgyeopsal and Galbi less than two times a week (p<0.05). The subjects in the department of food and nutrition took less vitamin B1 and more vitamin C and E than the subjects in the other departments (p<0.05). All subjects regularly exercised for 30 minutes to 1 hour (45.7%), one or two times weekly (43.5%). The subjects in the other departments consumed more nutrient supplements. Overall, 69.1% of the subjects consumed nutrient supplements. A total of 87.8% of the subjects in the other departments consumed alcoholic beverages and all subjects began to drink when they were in high school (50.4%). The primary reason given to continue drinking was to maintain good relationships with friends (76.7%). Overall, the results of this study indicate that students in the department of food and nutrition of Sahmyook university have better dietary habits and nutrient intake than those in other departments. The results highlight the necessary to introduce a practical method of inducing good dietary habits to the everyday life of students. One approach may be to provide greater opportunity for students in other departments to attend classes in the department of food and nutrition.

전지분유와 발효유를 이용한 치즈 유사품개발

조애리,노해원,김기성,정근희,전우민,Jo, Ae-Ri,Noh, Hae-Won,Kim, Kee-Sung,Chung, Keun-Hee,Jeon, Woo-Min 한국축산식품학회 2010 한국축산식품학회지 Vol.30 No.1

Imitated cheese was prepared from whole milk powder and fermented milk and the moisture content, general components, noncasein nitrogen, nonprotein nitrogen and free amino acids were analyzed to determine the optimal ripening conditions needed to produce imitated cheese that was similar to natural cheese. The moisture content of the imitated cheese was 40.27% one day after being produced. The cheese was ripened using two different methods; at $12^{\circ}C$ with vacuum sealing and at $12^{\circ}C$ and 95% RH with a spray of Penicillium camemberti. The lactose content decreased rapidly from 24.64 to 5.43% at the $4^{th}$ wk of ripening when it was ripened with Penicillium camemberti. The degradation of protein by mold ripening in the imitated cheese was more rapid than that of vacuum sealing. The flavor and body texture were optimal at the $4^{th}$ wk ripening. The noncasein nitrogen and nonprotein nitrogen content increased from 28.10 to 54.05, and from 6.58 to 23.06 mg/mL, respectively, when ripened with P. camemberti. When the cheese was ripened at $12^{\circ}C$, 95% R.H with P. camemberti after 4 wks, all free amino acids increased significantly except asparagines. The total free amino acid and bitter amino acid concentrations increased from 8.40 to 34.87, and from 1.53 to 10.02 nmol/mg, respectively. When the imitated cheese was prepared, the protein degradation and flavor of the cheese was better when ripened with P. camemberti.
