Dietary sodium intake and kidney tubular protein abundance in urinary extracellular vesicles.

Key takeaways

Forty-six healthy adults with normal kidney function tried a very low salt diet, then a high salt diet. The study measured proteins in their urine to see how the kidneys handled salt. It found that salt intake changed the amount of certain kidney proteins. This was a small test, so the results need more study to be sure.
