The purpose of this study was to investigate the effect of food behavior on dietary food intake status and health condition based on research of food behavior and nutritional intake status of university students in the Chungnam area. The average age, height, and weight of the subject group were 22.1 years old, 174.2 ㎝, and 67.0 ㎏ for the male students and 20.9 years old, 161.8 ㎝, and 53.4 ㎏ for the female students, respectively. From the nutritional intake status data, the averaged daily energy intake of both groups, male and female, are lower than the dietary reference intake(KDRI), as 2, 169.2 kcal and 1, 846.2 kcal, males and females, respectively. The lipid intake ratio was higher than the dietary reference figure, and the carbohydrate intake ratio was determined to be in the proper range. Male students(54.6%) and female students(52.0%) of the entire subject group skipped a breakfast mainly due to insufficient time, and the time at which meals were consumed, was determined to be irregular generally. In a day, male and female students have a heavier dinner than lunch(p<0.05), respectively. Meat and fishes are preferred by the entire subject group, and the number of students, who do not eat carrot and mayonnaise(p<0.05), was determined to be the highest, of all foods surveyed. The averaged daily activity coefficient and the resting energy expenditure shows significant difference(p<0.001) between two groups; was 1.7 and 1.6 and the second was 1, 404.3 kcal/day and 1, 292.5 kcal/day for the male and female groups, respectively. As the number of attempting to reduce body weight(p<0.001), the amount smoking(p<0.001), or the frequency of drinking alcohol increases, BMI decreases. On the other hand, as body shape satisfaction increases, BMI increases also.

The purpose of present study was to analyze mineral contents in various tissues and investigate theirs relation with bone mineral density (BMD) in rats. Fifteen Sprague-Dawley rats were fed standard diet for 4 weeks. Body weight gain, feed intake, and feed efficiency ratio were 41.00 g/week, 171.15 g/week, and 0.24 respectively. Among 12 minerals in serum, Ca is the highest with 6.86 mg/dl. Serum Mg, Se, and Cu were 2.52 mg/dl, 0.23 mg/dl and 0.22 mg/dl respectively. Mg contents in liver, spleen, and kidney were 246.36 μg/g, 105.01 μg/g, and 273.38 μg/g respectively. Tibia contents of Ca, Mg, Zn, Fe and V were 194.91 mg/g, 23.10 mg/g, 0.60 mg/g, 0.35 mg/g and 0.14 mg/g respectively. BMDs of right tibia and spine were 122.04 mg/cm2 and 153.61 mg/cm2. There were significantly positive correlations between tibia BMD and Se (p<0.05), tibia BMD and V (p<0.01), spinal BMD and V(p<0.05), respectively. It's expected that these results are used as a reference data in following study to elucidate physiological function of minerals.
