Comparison of sodium and potassium intake with excretion

J Schachter, PH Harper, ME Radin, AW Caggiula, RH McDonald and WF Diven

Nine well-motivated adults, knowledgeable about nutrition, kept food records, saved food portions equal to what had been eaten, and collected 24-hour urine samples for 3 consecutive days. Estimates of sodium and potassium intake were calculated from food table analyses of written food records and from flame photometric analyses of food portions. For each subject the mean of the estimates for each of the 3 days was compared with the mean of urine analyses for sodium and potassium for each of the 3 days. For the group of nine subjects, the average estimate of sodium intake from analyses of food records was 11% lower than the average estimate of urinary sodium excretion; the average estimate of sodium intake from analysis of food portions was 2% higher than urinary sodium excretion. For individuals, there were large differences between estimates of intake and measurement of sodium excretion. For the group of nine subjects, the average estimate of potassium intake from analysis of food records was less than 1% lower than the average estimate of potassium urinary excretion; the average estimate of potassium intake from analysis of food portions was 13% higher than potassium urinary excretion. For individuals, as with sodium, there were large differences between estimates of intake and measurement of potassium excretion.
