Barry Marshall infected his own stomach at Fremantle Hospital
The broth was alive — brown, murky, thick with Helicobacter pylori. This corkscrew-shaped bacterium burrows into the stomach wall. Barry Marshall was 32. He infected himself.
Medical textbooks said ulcers came from stress. Stomach acid sits near pH 2… strong enough to dissolve metal. Marshall and pathologist Robin Warren disagreed. They believed a bacterium was the cause, but he feared an ethics board would reject a human trial. So he drank the broth himself.
The bug turned out to be the most common infection on the planet.
More than half the planet hosts this bacterium. Most carry it for life without a single symptom. A team in Japan and at Johns Hopkins asked whether a cheap vegetable could push it back.
Broccoli sprouts reduced H. pylori colonization in a 48-person trial
Yanaka and Fahey ran the trial, published in Cancer Prevention Research, 2009. Forty-eight patients with confirmed H. pylori infections split into two groups. One ate 70 grams of broccoli sprouts each day. The other ate the same weight of alfalfa sprouts as placebo. Both held the routine for eight weeks.
Stool markers of H. pylori dropped by more than 40 percent in the broccoli group. Alfalfa sprouts changed nothing. Sulforaphane, a compound concentrated in young broccoli sprouts, did the work.
But the drop reversed within two months of stopping. And a bigger question sat behind the finding — the stomach bathes in acid strong enough to dissolve metal. How does a tiny bacterium survive in there at all?
Constipated? 🚫 Avoid This Fruit
You’ve probably heard that fruit and fiber help with constipation.
But one common fruit may actually make things worse…
Slowing digestion, making stools harder to pass, and leaving you feeling even more backed up.

H. pylori makes its own acid-proof bubble
Stomach acid sits near pH 2. It kills nearly every microbe on contact. But H. pylori carries an enzyme called urease, devoting up to 15 percent of its total protein to this single molecule.
Urease splits urea into ammonia, a base that cancels acid in a tiny zone around each bacterium. That shield is only half the trick. The enzyme also turns the thick mucus gel on the stomach wall into a watery liquid… and the corkscrew-shaped bug swims through, burrows in, and triggers chronic inflammation. Most carriers picked it up in childhood.
Helicobacter pylori: a childhood infection that lasts for life
About half the world carries this bacterium. Many pick it up in early childhood, passed along by family. It settles into the stomach lining and stays. Without treatment, the infection lasts decades.
In 10 to 20 percent of carriers, chronic inflammation leads to peptic ulcers, stomach cancer, or a rare lymphoma. Marshall published his self-experiment in the Medical Journal of Australia in 1985. He and Robin Warren won the 2005 Nobel Prize for proving a bacterium — not stress — causes these diseases.
Antibiotics can wipe the infection out. But certain foods can also make the stomach a harder place for H. pylori to hold on.
Four foods that help crowd out H. pylori
None of these replace prescription antibiotics. But each has been studied for reducing H. pylori's grip on the stomach lining.

🥦
Broccoli sprouts Sulforaphane cut H. pylori stool markers more than 40 percent in eight weeks |
🥤
Unsweetened cranberry juice Blocks H. pylori from gripping the stomach wall — 522-person trial, 20 percent fewer infections |

🥬
Sauerkraut Live Lactobacillus cultures compete with H. pylori for space on the lining |
🧄
Raw garlic Allicin slows bacterial growth and cuts H. pylori urease activity |
Each of these works from the food side. But one step matters more than any grocery item.
Add raw broccoli sprouts to one meal tomorrow
Buy a small container of broccoli sprouts at the store. Toss a handful onto eggs, a sandwich, or a salad. Raw sprouts carry the most sulforaphane.
| 🚫 Ignore months of recurring heartburn and keep buying antacids | ✅ Ask your doctor for an H. pylori breath test — it takes about fifteen minutes |
Marshall risked his own stomach because medical textbooks were wrong. One cup of sprouts and one conversation with a doctor… a gentler kind of proof.
He drank the bug to prove it was there.
You can fight it with your next meal.
Robin Warren first spotted spiral bacteria in stomach biopsies at Royal Perth Hospital in 1979. Many pathologists who saw the shapes dismissed them as contamination.
