37. The Root Cause of Asthma, Eczema, and Inflammation ft. Sam Garrett

February 25, 2026

Sam Garrett grew up in and out of emergency rooms with asthma and severe eczema. From ICU visits to hospital stays at National Jewish, his childhood revolved around medications, steroids, and trying to control symptoms that never fully went away.

But what ultimately changed everything wasn’t another prescription.

In this episode, Lisa sits down with her oldest son to unpack the turning points: the $100 elimination experiment, the moment milk triggered immediate wheezing, the law school years of dialing in nutrition for mental performance, and the surprising connection between food, inflammation, lung function, and focus.

If you’ve ever wondered whether what you eat really affects your asthma, skin, sleep, or energy, this conversation is real-life proof that it does.

In this episode, you’ll learn:

  • Food directly impacts asthma, eczema, and inflammation.

  • The itch-scratch cycle can be interrupted, but root cause matters.

  • Elimination diets reveal more than you expect.

  • Mental clarity and professional performance are deeply tied to nutrition.

  • Sleep, stress, and food all compound, for better or worse.

  • Listening to your body is a skill that must be learned.
