Abstract

This study was conducted to assess dietary intake and nutritional status of zinc and copper in Korean college women. Dietary survey was conducted by 24-hour recall method and fasting serum samples were collected from 111 apparently healthy subjects. Intake levels of zinc and copper were calculated using newly developed database for Zn & Cu of Korea food. Serum levels of Zn, Cu and activities of ALP, EC-SOD were measured from fasting serum sample. Mean daily zinc and copper intakes were 6.72mg/day(56.0% RDA) and 1.11mg/day respectively. Mean values of serum ALP activity, zinc and copper concentration were 43.9U/L, 14.8umol/1, 15.5umol/1and these values were mostly within normal range. EC-SOD activitis of the subjects were low and had no correlation with intake or serum levels of Zn, Cu. In conclusion, these results show that zinc and copper intake of Koran college women are lower than those from other counties but higher than those of adults in rural area of Korea. Their serum levels of Zn, Cu, ALP are relatively normal. These results indicate that marginal deficiency of Zn and Cu may be quite prevalent in these subjects but serum indicators measured may not be sensitive enough to detect such marginal deficiency. Further study in needed to develop a biochemical index sensitive enough to evaluate Zn and Cu status.
