It would seem that a very low or a very high sodium intake would increase the potassium requirement from the 2.2 plus or so minimum established so far. Please keep in mind that this is a bare minimum and makes no allowance for disease, perspiration, emotional storms, mild genetic defects, poisons, and odd intakes of other nutrients. Going below such a minimum would not severly degrade health normally, but it would probably make the most optimum performance degraded somewhat. I currently suspect that one to two grams per day is the desired amount of sodium which would give an approximately equal number of atoms. High ratios of potassium to sodium should not cause a problem.
Primitive tribes receive twenty to one ratios without apparent risk.
It is possible that people descended from tribes with a long history of eating primarily meat may need a little more sodium than others. In people who are nourished by unprocessed food, not assaulted by poisons in tobacco and liquor, and living a reasonable life, the regulatory systems should be able to tolerate a fairly wide range of sodium acute intakes. It is possible that chronic high intakes can eventually produce an intractable high blood pressure in some people, however. I do not know whether this causes any adverse health problems. It consistently affects the kidneys, usually by calcification at the corticomedullary junction.
