Gut Health Secrets: The #1 Habit Everyone Needs | Probiotics Don't Fix This

What if better gut health isn’t about adding more supplements, but understanding what your body actually needs?

At Biohackers World in New York, longevity journalist Klaudia Balogh talks with Sarah Greenfield, RD, TEDx Speaker and GutID Practitioner, about why gut health has become so overcomplicated, and what actually helps.

Sarah explains why your microbiome is more like an ecosystem than a list of “good” and “bad” bacteria, why random probiotics may not be helping, and how stress can affect your gut just as much as food.

What you’ll take away:

• Why food diversity and fiber matter more than most people think
• When microbiome testing is actually useful
• Why chronic stress can contribute to gut imbalance
• Why more supplements don’t always mean better results
• Simple ways to support your nervous system and digestion every day

Tune in to the full episode to hear how Sarah connects food, stress, microbiome testing, and nervous system regulation in a much simpler way.
