Decoding the Gluten Challenge: When and Why to Reintroduce Gluten with Registered Dietitian Erin Kenny

In this episode of Gluten-Free Unwrapped, Jenny sits down with registered dietitian and celiac disease expert Erin Kenny, founder of The Celiac Space, to tackle one of the most confusing topics in the gluten-free world: The Gluten Challenge.

If you've already gone gluten-free but never received a definitive celiac disease diagnosis, should you start eating gluten again for testing? How much gluten is required? For how long? And is a Gluten Challenge always necessary?

Erin breaks down the latest recommendations, explains who should and shouldn't consider a Gluten Challenge, and shares practical guidance for navigating the diagnostic process.

Jenny and Erin also discuss the story of a well-known gluten-free influencer who spent years believing he had celiac disease, only to discover through genetic testing that celiac was unlikely. His experience highlights the importance of getting the right testing and understanding what a diagnosis can—and cannot—tell you.

Whether you're newly gluten-free, questioning a past diagnosis, or trying to help a loved one navigate testing, this episode will help you better understand the path to answers.
