ADVICE

Do Proper Prep For Breath Tests

  • Prepare for breath testing by avoiding fibers, sugars, and alcohol 12–24 hours before the test.
  • Use inulin as the substrate and a 4-unit hydrogen rise as a positive SIBO indicator.
INSIGHT

H. pylori Has Two Faces

  • H. pylori can have protective and harmful roles, but overall populations fare better without it.
  • Dr. William Davis offers non‑antibiotic eradication protocols using vitamin C, black seed oil, and select probiotics.
ADVICE

Avoid Chronic Low‑FODMAP Diets

  • Avoid long-term low‑FODMAP or elimination diets because they worsen dysbiosis and reduce microbial diversity.
  • Use short-term restriction only for relief and then restore diverse prebiotics and fermented foods.
