Helicobacter: which diet helps?

The question of which diet helps against Helicobacter pylori is common, but the provided knowledge contexts contain no specific dietary advice. In general, diet alone cannot reliably eradicate H. pylori – standard treatment involves antibiotics plus a proton pump inhibitor. Some studies suggest certain foods may reduce bacterial load or protect the gastric mucosa: broccoli sprouts (sulforaphane), green tea (catechins), probiotics (Lactobacillus, Bifidobacterium), honey, and cranberries. However, the evidence is mostly mechanistic or from small human trials; large randomized controlled trials are lacking. Probiotics can also cause side effects like bloating. Crucially, diet should not replace medical therapy. Patients should be cautioned against self-treating with 'anti-Helicobacter diets', as this may delay diagnosis and effective treatment. The evidence base is mixed – there are hints of benefit but no strong clinical confirmation. No sources are available from the given context.
