To prepare for a Helicobacter pylori diet, focus on supporting antibiotic therapy rather than replacing it. Evidence suggests that certain foods may inhibit H. pylori: broccoli sprouts (sulforaphane), green tea, cranberries, garlic, and ginger. Probiotics (Lactobacillus, Bifidobacterium) can reduce antibiotic side effects. Avoid spicy, fatty, or acidic foods that irritate the gastric mucosa. However, dietary interventions have moderate evidence (clinical studies, but inconsistent results). Crucially, no diet alone eradicates H. pylori; triple or quadruple antibiotic therapy is standard. If you have a DNA test suggesting H. pylori risk, note that consumer genetics cannot diagnose active infection. Use a validated stool antigen or breath test. Evidence: practice/mixed. Caveat: always follow medical guidance.
