To study the relationship between sodium intake and urinary sodium excretion among young women, we carried out the following experiment. Experimental diet was consisted of three different levels of dietary NaCI intake (stage one, stage two, and stage three). A target levels of dietary NaCI intake was 5 g per day for stage one, and 13 g per day for stage two, and 20 g per day for stage three. For each stages, nine female students were taken one experimental diet for consecutive three days, and were collected all the urine through the experimental period. Sodium contents of a collected urine samples and all the foods included in experimental diet were analyzed for comparing urinary excretion rate of sodium on three stages. The following results were obtained. Mean urinary excretion rate of sodium for each stages was 62% for stage one, 75% for stage two, and 103% for stage three, respectively. Strong positive correlation was obtained between sodium intake and urinary sodium excretion.
