Abstract:
The purpose of this study is to investigate the concentration of plasma choline of Korean and to clarify the relationship between plasma choline concentration and choline intake. Plasma choline concentration of 30 young adults (15 males, 15 females) aged 20 - 30 years living in Deajeon metropolitan city are analyzed and their dietary choline intake. Choline content of one day meal was directly analyzed with the use of enzymatic method. Plasma choline concentration from more than 12 hr fasting blood was analyzed by using HPLC-MS. Choline intakes of male subjects were in the range of 253.51 - 1724.14 mg and those of female subjects were in the range of 240.85 - 938.06 mg. Mean intakes of choline were 634.53+/-353.68 mg in male subjects and 473.99+/-183.76 mg in female subjects. Plasma choline concentration of total subjects was in the range of 5.08 - 14.01 micro mol/L. Mean plasma choline concentration was 9.19+/-2.05 micro mol/L in male subjects and 8.11+/-1.70 micro mol/L in female subjects. Plasma choline concentration did not show significant correlation with choline intake in male and total subjects, but showed positive correlation with choline intake in female subjects (p<0.05). This result shows that more studies on large scaled samples are needed.
