Episode 80 - Food Sensitivities Explained with Dietitian Christa Biegler

Food sensitivities are more common than ever. But they’re rarely just about the food. 

In this episode, I’m joined by dietitian and functional health nutritionist Christa Biegler to unpack what food sensitivities really are, why restriction often backfires, and what your symptoms may actually be trying to tell you. We explore the roles of stress, digestion, the nervous system, and environmental factors like mold, and where to start if you’re feeling reactive to everything.

Christa and I talk about:

• What food sensitivities actually are (and how they differ from allergies and intolerances)
• Why food sensitivity testing can be misleading — and when it may (or may not) be helpful
• How stress and the nervous system impact digestion and immune responses
• Why restriction can create more reactivity and food fear
• The connection between gut health, digestion, and food reactions
• Why symptoms are signals, not problems to suppress
• How toxic burden (including mold exposure) can drive hypersensitivity
• Why reacting to “everything” is a sign the body is overwhelmed
• Simple, practical starting points if you suspect mold or environmental triggers
• How nervous system support plays a critical role in healing food sensitivities
• Why expanding, not shrinking, is often part of true recovery
