This study was conducted to investigate dietary lipid intakes and the plasma lipoprotein levels and fatty acid composition of eight healthy young Korean women for 7 days. After an overnight fast, blood samples were taken on the last day of dietary survey. The plasma were fractinated to very low-density lipoprotein(VLDL), low-density lipoprotein(LDL), and high-density lipoprotein(HDL) by ultracentrifugation. From each fraction, the content of triglyceride (TG), phospholipid(PL), cholesterol(CHOL), free fatty acid(FFA) and protein were determined. Fatty acid composition of total plasma lipid was alos analyzed. The subjects consumed 34.7$pm$2.8g of fat daily. The ingested amounts of EPA and DHA were 0.2 and 0.4g/day, respectively. They also consumed 112.2$pm$12.9mg of cholesterol per day. The concentrations of VLDL, LDL and HDL in the plasma were 66.5$pm$6.1, 114.0$pm$8.8 and 129.4$pm$5.1mg/dL, respectively, so the percentages of VLDL, LDL, and HDL were 20.7, 44.8 and 34.5%, respectively. The VLDL was composed of 27.5mg/dL of TG, 39.7 of PL, 58.8 of CHOL, 3.1 of FFA, and 22.4 of protein. The HDL had 10.7mg/dL of TG, 23.7 of PL, 18.7 of CHOL, 2.6 of FFA, and 73.7 of protein. In the plasma, linoleic acid was the most abundant fatty acid, followed by palmitic and oleic acid, the percentages of these 3 fatty acids were 30.8, 23.4 and 17.7%, respectively. The result indicated that the plasma levels of lipoprotein in the healthy young Korean women were slightly low and the levels of EPA and DHA were relatively high, compared to the data of other investigatiors. This might be due to the fact that they consumed less fat and cholesterol and higher EPA and DHA.
