The gut, often called the "second brain," has a profound impact on our health through the gut-brain axis, a communication network linking our gastrointestinal tract and central nervous system.

In this episode, Jen explains how disruptions in this system can lead to issues like food intolerances, underscoring the importance of maintaining a balanced gut microbiome for overall wellbeing.
