The hormone aldosterone is part of the sodium/potassium regulation 
system and having low normal aldosterone, a not uncommon problem, would 
result in faster than normal sodium excretion and would make you feel 
quite bad on a low sodium diet.  In fact, a high sodium diet would be 
recommended in this case.  This might be the reason that only 1/3 of 
people are salt sensitive, because their aldosterone is on the high 
normal side.  People with low to low normal aldosterone often have very 
strong salt cravings.  Their blood sodium and potassium often test in 
the lower half of the lab reference range.
