In order to prevent and evenmaybe (see below) help dissolving kidney stones, I read it is better to dramatically reduce salt intake (among other things). Some sites even recommend a 0-salt diet.
While in today's modern societies salt is one of the cheapest ingredients, and many people eat too much sodium, salt is nevertheless a necessary element for the body.
My question is related to medium sized kidney stones (~8 millimeters) that will require some time to go naturally out of the body, and salt intake:
- can the body rely on some sodium reserves during the time it takes to get rid of the intruder? (meaning no salt diet)
- or is it better to take a minimum of salt daily?
addendum
As for "does a low-sodium diet help preventing kidney stones?", a search for "low salt kidney stones" returns tons of pages related to the link between salt and calcium, and and the benefits of a low-salt diet.
As for "does a low-sodium diet help cure (dissolve) kidney stones?" I didn't find a page relevant enough that it deserves to be cited here. That was initially some guess work, which can be well wrong. But some people having a high sodium intake do build stones made in part of sodium. It was my guess that a low-salt diet (or drink a lot to dilute the urine) would produce urine having less salt than the stone itself, and therefore help dissolving it each time some urine is produced by the kidney and "washes" the stone.
