Intestinal paracellular phosphate absorption resists dietary adaptation but is upregulated in CKD.

Key takeaways

This lab study looked at how the gut absorbs phosphate, a mineral that builds up in kidney disease. It found that one absorption path does not adjust to diet and gets stronger in kidney disease. The work was done in the lab, not in people, so it explains biology rather than offering a treatment yet.
