The H. Pylori Diet: Best Foods to Eat, Avoid & Support Recovery
H. pylori is a spiral-shaped bacterium that sets up camp in your stomach lining and, according to the research, infects more than half the world's population. Most people carry it without ever knowing — no symptoms, no drama. But for others, it triggers chronic gastritis, stomach ulcers, and over time, a significantly elevated risk of stomach cancer. The standard treatment is a course of antibiotics combined with proton pump inhibitors, and it works well when completed fully.
So where does diet come in? Two ways, really. First, certain foods create an environment in your stomach that makes things harder for H. pylori — supporting the gastric lining, dampening inflammation, and competing with the bacteria for space. Second, some foods actively worsen things by cranking up stomach acid or irritating already-inflamed tissue. Knowing which is which gives you a real advantage during treatment and recovery.
My Take as a Nutritionist:
H. pylori is one of those infections that sneaks up on people. Most of my clients who have it didn't know for years — just chronic bloating, that nagging upper stomach discomfort, and a feeling that something was off. Once it's diagnosed, antibiotics are the standard route, and that's the right call. But what I've found in practice is that what you eat during and after treatment makes a real difference to how you feel and how well your stomach lining recovers. This guide walks you through the specific foods that the research supports, what to steer clear of, and how to think about diet as a layer of support alongside your medical care — not a replacement for it.
Why What You Eat Actually Matters With H. Pylori
H. pylori has a clever survival trick — it produces an enzyme called urease, which neutralizes the acid around it so it can survive in your stomach. Once it takes hold, it triggers inflammation in the stomach lining (gastritis) and slowly breaks down the protective mucous layer your stomach needs to keep acid from damaging tissue.
Diet influences this in two directions. Certain foods — particularly polyphenol-rich plants, fermented foods, and a few specific compounds — have been shown in research to inhibit H. pylori activity, support the gastric mucosa, and reduce inflammation. On the other side, a 2024 case-control study published in Food Science & Nutrition found a direct association between ultra-processed food consumption and H. pylori infection risk, even after adjusting for age, BMI, and energy intake. In other words, what you eat isn't incidental here.
One thing to be clear about upfront: if you've been diagnosed with H. pylori, food alone won't eradicate it. You need antibiotics for that. Everything in this guide is designed to work alongside your medical treatment — not replace it. If you're not sure whether what you're experiencing is H. pylori or something else, our guide to H. pylori symptoms, signs, and natural treatment is a good place to start.
Foods That Support a Healthier Stomach During H. Pylori
These aren't miracle foods. But they're the ones with real research behind them — some with clinical trials in humans, some with strong laboratory data. Think of them collectively as your stomach's support team while your body does the heavy lifting.
1. Broccoli Sprouts
If there's one food that keeps coming up in the H. pylori research, it's broccoli sprouts. The reason is sulforaphane — a compound found in high concentrations in young sprouts that has demonstrated bactericidal activity against H. pylori, including strains that are resistant to common antibiotics.
In a randomized controlled trial, 48 H. pylori-positive patients consumed 70g of broccoli sprouts daily for 8 weeks. The sprout group saw significant reductions in H. pylori colonization markers and gastric inflammation — results that faded once they stopped. More recently, a 2024 systematic review in Frontiers in Medicine looked at the full body of evidence on Brassicaceae-rich diets and concluded that broccoli sprouts, kale, cabbage, and similar vegetables show real potential to reduce H. pylori colonization as an adjunct to antibiotic therapy. Complete eradication through diet alone? Unlikely. But meaningful support? The evidence is there. For a deeper look at another natural compound with H. pylori research behind it, see our article on mastic gum and H. pylori.
Practical note: Go for 60–70g of fresh 3-day-old sprouts daily. Mature broccoli florets have significantly less sulforaphane. The clinical research suggests you need around 100 µmol of sulforaphane daily to hit the effective range — that's roughly 60–70g of fresh sprouts.

2. Manuka Honey
Manuka honey isn't like regular honey. The difference is methylglyoxal (MGO) — a compound unique to manuka that gives it antibacterial activity well beyond what hydrogen peroxide alone can do. In lab research, all five H. pylori isolates tested showed sensitivity to a 20% manuka honey solution. More recent cell studies have shown it inhibits the inflammatory pathways H. pylori activates (NF-κB and AP-1), and dials down COX-2 expression — one of the key drivers of gastric inflammation.
Clinical trials in humans are still limited, so this one is best treated as a supportive food, not a standalone treatment. One teaspoon 20 minutes before meals is the approach used in the research. Look for UMF 10+ or MGO 100+ on the label — anything below that likely won't have the therapeutic-grade antibacterial activity you're after. And don't add it to hot tea — heat above 40°C degrades the active compounds.
Worth knowing: Manuka honey is naturally high in sugar. If you have diabetes or insulin resistance, check with your doctor before using therapeutic doses regularly — it can affect blood glucose levels.

3. Probiotic-Rich Fermented Foods
Your gut microbiome takes a hit during H. pylori infection — and antibiotic treatment, while necessary, compounds that. Fermented foods help restore balance by introducing beneficial bacteria that compete with H. pylori for space on the stomach lining. Lactobacillus and Bifidobacterium strains in particular have been shown to reduce the side effects of triple therapy — less diarrhea, less bloating, less of that metallic taste — and may improve eradication rates.
Best sources: yogurt with live cultures (check the label — not all yogurt qualifies), kefir, unpasteurized sauerkraut and kimchi, and miso. Aim for at least one serving daily, and if you're on antibiotics, take your probiotic at least 2 hours away from your dose so the antibiotics don't kill the beneficial bacteria before they can do anything. For more on how probiotics interact with gut infections, see our guide to probiotics for parasites and candida.
4. Cranberry
Cranberry's reputation for urinary tract health has overshadowed its gastric research — and that's a shame, because the evidence for H. pylori is genuinely solid. The proanthocyanidins in cranberry inhibit H. pylori's ability to adhere to the stomach lining. A double-blind, randomized, placebo-controlled trial published in 2021 found that daily cranberry intake suppressed H. pylori infection, with the strongest effect at 44mg of proanthocyanidins per day consumed twice daily over 8 weeks.
Go for unsweetened cranberry juice or a standardized extract rather than juice cocktails — the added sugar in cocktails does your inflamed stomach no favors. One heads up: straight cranberry juice is acidic, and if you're already dealing with reflux or GERD symptoms alongside your H. pylori, it can make things worse for some people. In that case, an encapsulated extract is the gentler option.

5. Garlic
Raw garlic contains allicin — a sulfur compound with broad-spectrum antimicrobial activity that multiple lab studies have shown inhibits H. pylori. Epidemiological research has also found that low intake of allium vegetables like garlic is one of the dietary risk factors most consistently associated with H. pylori infection severity. Garlic's antimicrobial reach extends well beyond H. pylori too — if you're curious about the full picture, we have a detailed article on garlic for parasites.
Two cloves a day, raw or lightly cooked, is a reasonable target. Raw gives you the most allicin, but if your stomach is already tender and inflamed, start with lightly sautéed garlic in olive oil — it's much better tolerated. And if raw garlic is worsening your symptoms rather than helping, stop. A sensitive stomach that's already irritated doesn't need more irritation.
6. Green Tea
Green tea's catechins — a family of polyphenols — have demonstrated antibacterial effects against H. pylori in laboratory research, including inhibition of the bacteria's urease activity. The epidemiological picture is also interesting: populations with higher green tea consumption tend to show lower rates of H. pylori-associated gastric disease. The human clinical evidence isn't as strong as broccoli sprouts or cranberry, but it's a low-effort daily addition with a solid biological rationale.
Two to three cups a day is a reasonable amount. If caffeine is a concern during active infection, gyokuro and matcha are lower-caffeine options. And if green tea on an empty stomach worsens your nausea, have it with food instead.
7. Extra Virgin Olive Oil
Extra virgin olive oil contains oleuropein and hydroxytyrosol — polyphenols that have shown antibacterial activity against H. pylori in lab studies, and which a review of natural products identified as among the few with both in vitro and early clinical evidence. Beyond its potential direct effect on H. pylori, olive oil is anti-inflammatory and easy on the digestive system — exactly what you want when your stomach lining is already under stress.
Make it your primary cooking fat, drizzle it over cooked vegetables, and keep the heat reasonable when cooking — high-temperature frying degrades the polyphenols.

What a Day of Eating Might Look Like
This isn't a rigid plan — it's a framework showing how to structure your day around gut-supportive foods while avoiding common irritants. Adjust portions and options to what works for your stomach. If you're also dealing with broader gut dysbiosis alongside H. pylori, our parasite detox diet guide covers complementary dietary principles that apply here too.
Breakfast:
Plain yogurt with live cultures, a handful of blueberries, and a drizzle of manuka honey. One cup of green tea on the side. Or, if you prefer something more substantial: scrambled eggs with sliced avocado on sourdough.
Mid-morning:
4oz of unsweetened cranberry juice, or a small serving of mixed berries. Good time for a probiotic supplement if you're using one — just keep it well away from any antibiotic doses.
Lunch:
Grilled salmon or chicken with broccoli sprouts added to whatever you're eating, steamed zucchini or cooked carrots, dressed with extra virgin olive oil and lemon. Simple, easy on the stomach, and packs in several of the key foods at once.
Afternoon:
A cup of green tea. A small bowl of kefir, or a handful of plain crackers if you need something more.
Dinner:
Baked white fish with garlic-infused olive oil, cooked peeled vegetables, and white rice. Stick with cooked vegetables rather than raw salads during active symptoms — the reduced fiber load is genuinely easier on an inflamed stomach lining.
Before bed:
One teaspoon of manuka honey (UMF 10+) about 20 minutes before sleeping, especially if you're dealing with nighttime discomfort.

Practical Tips for Eating During Treatment
-
Eat smaller, more frequent meals — 5 to 6 smaller ones rather than 3 large ones reduces gastric distension and acid pooling
-
Slow down and chew thoroughly — it reduces the workload on your stomach and minimizes discomfort
-
Drink water between meals rather than during — drinking a lot with meals increases gastric volume and can worsen symptoms
-
Keep probiotics at least 2 hours away from antibiotic doses — otherwise the antibiotics kill the beneficial bacteria before they can do anything
-
Don't eat within 2 to 3 hours of lying down — it significantly reduces nighttime reflux
-
Reintroduce raw vegetables and higher-fiber foods gradually once symptoms improve — no need to rush
-
Know what die-off looks like — as H. pylori begins to clear, some people experience a temporary worsening of symptoms. This is normal and worth being prepared for.
After Treatment: Make Sure It Actually Worked
Completing a course of antibiotics doesn't automatically mean H. pylori is gone. Antibiotic resistance rates are rising, and incomplete eradication is more common than most people realize. This matters — untreated or partially treated H. pylori carries significant long-term risk of peptic ulcers and gastric cancer.
The standard recommendation is to retest 4 to 6 weeks after finishing antibiotics using either a urea breath test or a stool antigen test. Both are non-invasive and highly accurate. Blood antibody tests are not the right tool here — they can stay positive for months after successful eradication and will give you a false reading. During the recovery phase, supporting your body's natural detox pathways with the right binders can also be a useful part of your protocol.
See a doctor urgently if you experience: black or tarry stools, vomiting blood, severe persistent abdominal pain, unexplained weight loss, or difficulty swallowing. These may indicate a peptic ulcer complication or another serious condition that needs immediate evaluation — don't wait.
