  • Is potassium-induced natriuresis (with NCC dephosphorylation) preserved in CKD?

  • Does CKD cause a switch from urinary K+ excretion to gastro-intestinal K+ excretion or intracellular redistribution?

  • In CKD, do the beneficial effects of dietary K+ outweigh the risks of hyperkalaemia?

  • Are the positive effects of dietary K+ mediated by plasma K+ and, if so, are they concentration dependent?

  • What is the effect of dietary K+ on phosphate balance and fibroblast growth factor 23?
