This study was undertaken to evaluate the potassium consumption and excretion in forty healthy male workers of a tire company in Seoul. Mean postassium intake for three days in the subject was $54.5\pm16.7mEq/day(2.13\pm0.64g)$ and urinary excretion of potassium in 24 hours was $45.9\pm10.5mEq(1.77\pm0.41g)$. Thus 83% of dietary potassium was excreted in the form of urine. Dietary ratio of Na to K was $4.15\pm0.58$ while urinary ratio of Na to K was $5.20\pm1.11$. The main food source of potassium was cooked rice with soybean in the rice group, potato with soybean paste soup in the part of soup group. and seasoned Spanish mackerel with raddish in the side dish group. There was a strong correlation between dietary protein and dietary potassium(r=0.694, p<0.001). Urinary sodium and potassium were also strongly associated with each other(r=0.647, p<0.001).
