PKD nutrition is different from general healthy eating
And understanding the “why” changes how you approach the “what.”
Diet influences kidney workload, inflammation, and metabolic stress
PKD is genetic—but progression is not fixed
Small, consistent inputs shape long-term outcomes
A structured starting point for PKD nutrition
Think of this as a set of clear, focused learning modules—similar to the kind of guidance you’d want from a stack of high-quality clinical handouts, all in one place.
Not a comprehensive program. Not a rigid plan.
Just a credible foundation you can build from.
5 short modules. The core questions, answered clearly.
Each module focuses on one foundational area—combining current evidence with practical application.
Clearing the Noise
What research supports vs. myths. Core dietary patterns in PKD. Stop over-complicating your plate.
Fluids & Sodium
Fluid intake and vasopressin physiology. Sodium’s role in blood pressure control and progression.
Carbs & Sugar
Insulin, glucose, and kidney stress. What “cutting carbs” actually means for long-term health.
Oxalates & Protein
When oxalates matter (and when they don’t). Protein precision: finding the right amount and type.
Fasting – Risk or Reward?
Current knowledge on fasting in PKD, potential metabolic mechanisms, and safety considerations.
Built by a team focused on PKD nutrition
This series is created by Kelly Welsh, RD, a Registered Dietitian and PKD patient, in collaboration with the Kidney Nutrition Institute.
Since 2020, KNI has worked extensively with PKD patients to translate emerging research into practical, real-world nutrition strategies.
This content reflects both current evidence and clinical experience.
After going through this series, you’ll have:
A clearer understanding of key nutrition variables in PKD
Confidence in what matters most (and what doesn’t)
A practical starting point you can build from
Better context for conversations with your care team
Start with a clear foundation
Free. Evidence-based. Designed to give you a solid starting direction.
