Abstract:
The purpose of this study was to investigate Na and K balances in healthy adult women. Anthropometric assessments, biochemical analysis of blood, 3-day dietary flood records and collections of 3-day food, 24-hr urine and faces were performed to evaluate intakes and excretions of Na and K in 20 college women living in Seoul. The mean BMI and blood pressure of the subjects were 21.08 and 110.25/67.50mmHg, respectively. Mean daily intake of energy was 1578.84 kcal, 79% of Korean RDA. Also, daily intakes of Na and K ware 120.86mEq and 44.20mEq. The urinary and fecal excretions of Na were 99.88 and 4.45mEq/day, and those of K were 30.41 and 8.66mEq/day, respectively. The body retention, retention rate, and apparent absorption of Na were 17.11mEq, 13.23%, and 96.31%, and those of K were 5.82mEq, 8.69%, and 80.12%, respectively. The urinary and fecal Na/K ratio were 3.48 and 0.52. There were significantly positive correlations between 1) urinary Na, K excretions and intakes of Na or K, 2) urinary K and BMI, 3) serum K and serum globulin, and 4) urinary Na excretion and serum haptoglobin level, respectively. The results of this study show that Na intake was higher and K intake was lower than those of other advanced nations. Therefore, nutrition education show instruct people to reduce Na intake and to increase K intake.
