🥗 Nutrition science is always evolving—and that means staying curious.

Not everything we once learned about nutrition holds up as new research emerges, especially protein. In this conversation with our Director of Nutrition: Kathy Jensen, MS, RDN, we break down protein: how much is enough, what’s kidney-safe, and how to stay in ketosis while meeting your protein needs.

🥩 Protein isn’t the enemy—carbs may be the bigger concern.

This clip is from our recent interview with Dr. Ian Lake which is now up on our youtube channel!

Our Ren-Nu Scientific Director, Dr. Melina Messing, speaks with Dr. Ian Lake about the importance of metabolic health and the story behind his book, Shifting Gears: The 1,000-Mile Ride That Changed My Mindset on Type 1 Diabetes.

While the conversation centers on Type 1 diabetes, many of Ian’s insights into metabolic health, resilience, and understanding your own body are also highly relevant to people living with PKD.
