Lay opinion vs evidence: Helicobacter Ernährung

The question of diet for Helicobacter pylori (Hp) illustrates the gap between lay opinion and evidence. Common advice includes garlic, broccoli sprouts, cranberry, green tea, and probiotics to eradicate the bacteria. Scientific evidence is weak to moderate. In vitro and some small human studies suggest certain compounds (e.g., sulforaphane from broccoli) or probiotic strains (Lactobacillus, Bifidobacterium) may inhibit Hp growth. However, effect sizes are small, studies are heterogeneous, and results are not consistently replicated. The established treatment remains antibiotic-based triple or quadruple therapy with proton pump inhibitors. Diet can play a supportive role but cannot replace medical therapy. Crucially, untreated Hp infection can lead to gastritis, ulcers, or gastric cancer. Lay opinions promoting 'natural cure' may delay effective treatment. Evidence grade: mechanistic/unclear.
