A dose-controlled protocol for introducing fermented foods while minimizing flare risk.

Quick answer

Fermented foods can help long-term gut resilience, but only if introduced with dose control. Start tiny, go slow, and monitor delayed reactions.

Starter protocol

  • Pick one food for the first 3-4 days.
  • Start with 1-2 teaspoons.
  • Increase every 48 hours if stable.
  • Keep other diet variables steady.

Bottom line: method beats enthusiasm. Controlled introduction prevents setbacks.
