[Use of sodium chloride in the German Federal Republic (author's transl)].

In order to obtain data on the amount of sodium chloride used in the German Federal Republic, 106 persons of different social groups, with healthy kidneys, were investigated, measuring the sodium chloride contents in their 24-hour urine. The sodium chloride intake follows from the sodium chloride secretion because the regulation of the sodium household is effected through the renal excretion, and with healthy people the daily intake of sodium chloride down to a limit value of 200 mVal per day is eliminated without delay. The values measured are between 4.7 and 32.7 g, the mean figure corresponded to 13.1 g.
