Can diet alone prevent H. pylori–related cancer?

While a healthy diet rich in fruits, vegetables, antioxidants, and fiber can lower inflammation and may reduce some risks linked to H. pylori infection, diet alone cannot fully prevent cancer. Eradicating H. pylori with proper medical treatment (usually antibiotics plus acid-suppressing therapy) remains the most effective way to lower long-term cancer risk. Diet is best used as a supportive measure alongside medical care.
