| Summary: | Evidence demonstrates a positive association among the high intake of sodium together with the
lower intake of potassium with the high levels of blood pressure. 121 adults individuals clinically healthy were studied. They were individuals of both sexes, between 19 and 59 years old, taken at random in different areas of the city of Posadas, from whom the sodium and potassium electrolytes homeostasis was evaluated through the intake and the urinary excretion. The population consumes 7 to 15 daily grams of salt (184 +/- 68 mMol/day), 1,1 to 2,4 grams of potassium (45 +/- 16 mMol/day) with 4.2 ± 1.4 of Na/K urinary ratio. Our data indicate that the population studied presents a high intake of salt and low intake of potassium, with a high Na/K urinary ratio, constituting a critical environmental factor that contributes to a higher prevalence of hypertension. This has motivated the implementation of approaches at world level which recommend to relationship between Na/K urinary ratio nearing 1, corresponding mainly to a moderate entrance of 100 mMol/day of sodium and an appropriate intake of 90 mMol/day of potassium in hypertensive patients which could be beneficial for all population.
