[Experimental studies aimed at setting standards for the optimal salt composition of drinking water]

As known, the concentration of salts in potable water determines water intake in a certain degree. Water with marginal concentrations of salts brings about increased water consumption. This causes tension in the renal and extrarenal excretory mechanisms and, as a result, leads to unjustified (from the point of view of expedient behavior) energy expenditures that are not induced by environmental factors. The optimal variant is water with a salt concentration of 500 mg/l and 250 mg/l. Tap water as well as water with a salt concentration of 100 mg/lg occupy an intermediate position between desirable and undesirable waters but lie closer to the optimal variant.
