57 foods in this collection
High-sodium foods are a hidden stone risk because sodium makes the kidneys excrete more calcium into the urine, and urinary calcium is a primary stone ingredient. The general daily target is under 2,300 mg, and the sodium hides mostly in processed and packaged foods rather than the saltshaker. For stone patients, sodium interacts with the oxalate column: a low-oxalate food can still be stone-risky through sodium, which is why this tag exists alongside the oxalate ratings.
