This study was conducted to determine the effect of seaweed ingestion on Na, Ca and K balances in healthy male subjects and to elucidate possible hypolipidemic mechanisms. Six subjects were given a nutritionally controlled diet based on their usual intake for 5-days followed by 5 days in which seaweed was added to the basal diet. Based on the results of the study, the relation between the levels of intake and excretions in stool, urine and serum concentrations was analyzed. In this study, the ingested sodium and potassium were mostly excreted in urine. The highest the rate of urinary excretion to intake for K at 64%, followed by 56% for Na, Conversely, Ca was excreted in stool at higher rates. Analysis of the relation between the intake and excretion in stool revealed that Na and K showed a positive relation with statistical significance. There was no statistically significant relation between the intake and serum concentration of any these minerals. The levels of serum cholesterol and triglyceride were remarkably reduced (p<0.05) by seaweed intake. Thus, the results suggest a beneficial effect of seaweed on Na, Ca, K metabolic control and hypolipidemic mechanism of the healthy male subjects.
