Brief Summary

Patients with end-stage kidney disease have hyperphosphatemia and accumulated uremic toxin level due to decreased urine excretion ability. Unhealthy diet causes altered mineral metabolism, elevated uremic toxin level, immune dysregulation, and inflammation. The investigators hypothesize that therapeutic diet intervention reverses altered mineral metabolism, elevated uremic toxin level, immune dysregulation, and inflammation. In this study, the investigators crafted 7-day special healthy diet to illustrate the clinical implications of therapeutic diet for dialysis patients.
