Broccoli Sprouts, Cranberry and Green Tea: Foods Studied Against H. pylori

HealAlright Editorial Team · 11 November 2026 · 1 min read

Researchers around the world have looked at whether certain foods can help against H. pylori. Some results are interesting, but none of these foods replaces medical treatment.

Broccoli sprouts

Broccoli sprouts are rich in sulforaphane. Small human studies found that eating them daily lowered markers of H. pylori activity and stomach inflammation, but did not reliably eradicate the infection.

Cranberry

Compounds in cranberries may make it harder for H. pylori to stick to the stomach lining. Some trials suggest cranberry juice may modestly improve treatment results when taken alongside standard therapy. Choose unsweetened or low-sugar options.

Green tea

Laboratory and animal studies suggest green tea compounds may inhibit H. pylori. Evidence in people is limited, and very strong tea on an empty stomach can irritate some people.

Garlic

Garlic shows antibacterial activity in the laboratory, but human studies have been disappointing. Large amounts of raw garlic can also cause heartburn.

Fermented foods

Yoghurt and other fermented foods may help reduce side effects during treatment.

The right way to use these foods

Include them as part of a balanced diet
Never use them instead of prescribed treatment
Watch for foods that trigger your symptoms

Key takeaway

Some foods may support your stomach, but none has been shown to cure H. pylori on its own. Eat well, and pair good food with proper treatment and a confirmation test.
