I eat so much sodium it's ridiculous. Your body will adjust to whatever becomes "normal" for you. Unless you have some other health issue, nature will take care of itself and regulate your body to homeostasis.
Obviously there's times when more or less are better, but overall, your enjoyment of food and overall diet is way bigger than simply sodium content. You won't gain or lose weight based on that alone unless your looking at the diff between stage ready at 4%bf and zero water retention and a bloated 6%
