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.

This study was conducted to obtain principal data on nutrition education according to college major after analyzing the nutrition status of 302 male university subjects. The 302 male subjects consisted of male students majoring in literature and science (109), food and nutrition (94), and physical education (99). Exactly 47.9% (highest among the groups) of male students majoring in food and nutrition ate regular meals, 39.4% ate breakfast. Precisely 29.4% of subjects majoring in literature and science never ate out. Exactly 23.2% of subjects majoring in physical education over ate frequently, and 31.3% enjoyed eating out. Intakes of protein, fat, vitamin A, B1, B2, B6, C, E, folic acid, Ca, Fe, sodium, and cholesterol among male students majoring in food and nutrition appeared to be significantly higher compared to those of other groups (p<0.05). Intakes of energy, Zn, dietary fiber, and cholesterol among male students majoring in physical education were higher, whereas intakes of all nutrients except for dietary fiber by subjects majoring in literature and science were lower than the other two groups. Exactly 20.2% of male students were interested in health. We found that 52.4% of subjects considered exercise as an important factor for maintaining health. Smoking rate was the highest (43.6%) among male students majoring in nutrition, and the drinking rate was highest (56.0%) among male students majoring in literature and science. We found that smoking was continued as a habit (61.5%) while drinking was essential for social relationships (73.9%). From this study, it was found that male students have problems associated with eating regular meals, skipping breakfast, overeating, and intake of unbalanced foods. Also, male students who majored in food and nutrition demonstrated problems in applying their knowledge to proper dietary habits. In conclusion, a systemic educational program needs to be introduced to promote healthful dietary habits in male students.

In this study, the effects of intake of Acer mono Max. seed oil, and Magnolia denudata seed oil on the lipid levels of mouse blood were compared to those of commercially available vegetable oils. FiveICR mice were each fed a corn oil, Acer mono Max. seed oil, and Magnolia denudata seed oil supplemented diet for a total of 8 weeks. The serum profiles of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were high in palmitic acid, oleic acid, and linoleic acid. The saturated fatty acid contents of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were 3.95% and 0.88%, whereas the unsaturated fatty acid contents were 8.71% and 4.60%, respectively. The liver and spleen weights of mice fed Acer mono Max. seed oil were higher than those fed corn oil (p<0.05). Total cholesterol level was highest in mice fed Acer mono Max. seed oil (p<0.05), whereas there were no significant changes in the cholesterol levels of mice fed Magnolia denudata seed oil and corn oil. The HDL-cholesterol levels in mice fed Acer mono Max. seed oil (175.80±27.66 ㎎/㎗) and in those fed Magnolia denudata seed oil (145.20±19.10 ㎎/㎗) were higher compared to those of mice fed corn oil (p<0.05). In conclusion, there were no significant differences in fatty acid composition between mice fed Acer mono Max. seed oil and Magnolia denudata seed oil. Future study on the antioxidant effects of seed oils should be carried out.

This study focused on the yearly-dietary habits, nutrition status, and health of female students residing in Seoul. A number of classes were assess based on their dietary behaviors in oder to attempt to determine differences in their attitudes to nutrition, according to age. The students of class 2011 (sophomore) ate meals more regularly than the female students of the 2008 class (p<0.05). It was found that sophomore female students of class 2008 consumed higher than average nutrient intake. Sophomore female students of the 2011 class consumed lower than average vitamin B₂, C, Ca, and Fe intakes. Folic acid in take was lower than average in both groups. Phosphorus and sodium intakes in both groups were excessive (p<0.05). When surveyed, sophomore female students of the 2008 class believed that the most important thing for health was exercise, whereas students of class 2011 believed that nutrient intake was the most important factor (p<0.05). Female students of the 2008 class exercised 1～2 times a week generally, whereas students of class 2011 exercised three times (43.2%) (p<0.05). Therefore, it is necessary to study changes in dietary habits and health status according to the age of students, and develop specific nutrition education programs for female students.

The purpose of this study was to compare the awareness of dietary patterns and health of full-time and employed housewives. The investigation gathered information on general characteristics, dietary lifestyle, nutritional status, and health by questionnaire as well as anthropometric measurements. The subjects included housewives living in Seoul and Gyeonggi Province (86 full-time and 127 working housewives) during November 2009 to January 2010. The average age, height, and weight of the housewives were 45.8±7.6 yr, 161.0±8.4 cm, and 55.7±6.3 kg, respectively. The average monthly income of the households was 3 million to 5 million won (31.4% full-time and 37.0% working housewives), and their average food expense was 200,000 to 500,000 won (46.5% full-time and 48.1% working housewives). More than 90% of the studied homes were nuclear families and the most common number of children was 2 to 3 (79.1% full-time and 76.4% working housewives). The ratio of employed housewives who ate regular meals was 35.4%, but that of the full-time housewives was 48.2% (p〈0.05). Of the working housewives, 7.1% never ate breakfast and the primary reason for skipping breakfast was 'busy in the morning' (61.1%). The type of food that the housewives preferred when eating out was Korean food, both for the full-time and employed housewives (76.0%). All the housewives overate calories and the full-time housewives ate more protein, fat, vitamin A, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E, folic acid, and cholesterol than the employed housewives (p〈0.05). Both the full-time and employed housewives were more satisfied with supper than with other meals. About 30.6% of the full-time and 33.9% of the working housewives had no interest in health, but answered that regular exercise was very important for health (33.3% full-time and 39.7% working housewives). In conclusion, working housewives have poor dietary habits and nutrient intakes, thus substantial measures to improve these problems are urgently needed.
