The H. Pylori Diet: Foods to Eat, Foods to Avoid & a Full Meal Plan

An H. pylori diet is an eating approach designed to support antibiotic treatment for H. pylori infection and reduce stomach irritation, but it cannot cure the infection on its own. Focus on probiotic and anti-inflammatory foods such as yoghurt, broccoli sprouts, honey and green tea, while limiting spicy, fried, acidic and processed foods, alcohol and excess caffeine. Diet should support a doctor-confirmed H. pylori eradication protocol, not replace medical treatment.

Helicobacter pylori (H. pylori) is a bacterium that can colonise the stomach lining and cause chronic gastritis, stomach ulcers, and chronic inflammation of the stomach lining over time, while also increasing the risk of gastric cancer.

The World Health Organization’s International Agency for Research on Cancer (IARC) classifies chronic H. pylori infection as a Group 1 carcinogen because of its established role in causing cancer. An H. pylori diet is a supportive eating approach used alongside treatment to reduce irritation in the digestive tract, help manage gastritis symptoms, and focus on foods that are easier on the stomach rather than trying to cure the H. pylori bacteria on its own.

Some people do not experience symptoms at first, while others develop H. pylori symptoms such as stomach pain, burning, bloating, nausea, and other gastritis symptoms linked to irritation of the gastric mucosa.

If you’re experiencing persistent digestive symptoms or want to confirm an active H. pylori infection, MyDiagnostics offers an at-home H. pylori stool antigen test that detects active infection without fasting.

Diet can be useful as supportive care because certain foods may be easier on an irritated stomach, may be less likely to aggravate gastric acid and gastric juice, and can provide fibre and nutrients that support overall gut health. However, diet does not eradicate H. pylori or replace the appropriate treatment plan.

The American College of Gastroenterology (ACG) recommends medical eradication therapy, which uses combinations of antibiotics and acid-suppressing medicines, including proton pump inhibitors that reduce stomach acid production, with the exact regimen selected according to factors such as previous antibiotic exposure and resistance patterns.

For people recently diagnosed with H. pylori, managing digestive symptoms during treatment, or recovering after eradication therapy, this guide explains foods to eat and avoid, probiotic and supplement options, how an H. pylori diet compares with a general gastritis diet, a sample 7-day meal plan, and when to work with a healthcare provider. Food tolerance varies considerably, so a food that triggers burning, bloating or nausea for one person may be well tolerated by another.

No food has been proven to eradicate an established H. pylori infection. Some foods and dietary compounds have demonstrated antibacterial, anti-adhesion, antioxidant or symptom-supporting effects in laboratory or human studies, but they should be viewed as complementary rather than curative.

A practical H. pylori diet therefore focuses on nutrient-dense, minimally processed foods that are well tolerated. This approach is broadly consistent with WHO guidance favouring fruit, vegetables, whole grains, pulses and minimally processed foods.

Yoghurt containing live cultures, kefir and other fermented foods such as sauerkraut, kimchi and miso can provide beneficial microorganisms and beneficial bacteria that may support gut health. Probiotic supplementation has been studied alongside H. pylori eradication therapy, with evidence suggesting that some probiotics may improve eradication outcomes modestly and reduce treatment-related gastrointestinal side effects.

Among the organisms studied, Lactobacillus reuteri and Saccharomyces boulardii have received particular attention. A recent meta-analysis found that S. boulardii supplementation alongside eradication therapy was associated with improved eradication rates and fewer adverse effects such as diarrhoea, nausea and epigastric pain, and probiotics may also help restore intestinal flora during antibiotic treatment to support digestive health.

Choose plain, unsweetened yoghurt or kefir where possible, particularly if added sugar or very sweet foods worsen symptoms. Fermented foods should be introduced gradually if you are not accustomed to them, because they can cause temporary bloating in some people. During recovery, these gentle probiotic options may also be easier to tolerate when you need easily digestible foods.

Broccoli sprouts are among the most studied foods in relation to H. pylori because they contain glucoraphanin, which can generate the compound sulforaphane. In a human trial, daily consumption of sulforaphane-rich broccoli sprouts reduced markers of H. pylori colonisation and gastric inflammation, although the effects were not permanent after the intervention stopped.

Garlic and onions contain sulphur compounds and other bioactive substances with antimicrobial activity, while green tea contains polyphenols that have demonstrated antibacterial activity in experimental research.

Foods high in flavonoids may also help inhibit H. pylori growth and limit harmful bacteria in the stomach. These foods can be included as part of a balanced diet if they do not worsen individual symptoms, but they should not be described as H. pylori cures.

Raw honey, including Manuka honey, is also frequently promoted for its antimicrobial properties. However, evidence that honey alone can eradicate H. pylori in humans is insufficient, so it is better viewed as an optional food rather than a treatment.

Cranberries and unsweetened cranberry products have also been investigated. Randomised trials have found that cranberry consumption may suppress H. pylori colonisation in some circumstances, but a systematic review and meta-analysis concluded that the overall evidence was not strong enough to establish cranberry as an eradication treatment.

If the stomach lining is inflamed, relatively mild foods may be easier to tolerate than heavily spiced, acidic or greasy meals. Oatmeal, bananas, cooked non-acidic vegetables, rice, potatoes and other simple whole foods can form the basis of meals when symptoms are active.

Easily digestible foods and other easily digestible carbohydrates, including rice, potatoes, oatmeal and similar starches, are often better tolerated when gastritis symptoms are active. Gentle options can also include wheat starches and peeled or cooked fresh fruits, especially non-acidic fruits if fruit is tolerated.

High protein foods that are lower in fat, including skinless poultry, fish, eggs and some lean red meats, can be easier to manage than fried or processed meat products, and these lean proteins provide necessary building blocks for tissue repair. Steaming, baking, grilling or lightly sautéing these foods with a small amount of olive oil is generally preferable to deep-frying.

High-fibre foods, including oats, whole grains, apples and leafy vegetables, can contribute to overall digestive and metabolic health, although very high-fibre meals may aggravate bloating in some people. Foods high in flavonoids may inhibit H. pylori growth.

There is no universal H. pylori “forbidden food” list because individual tolerance differs. However, certain foods and drinks commonly worsen upper gastrointestinal symptoms, particularly when gastritis or an ulcer is present.

A useful strategy is to reduce foods that cause burning, reflux, nausea, bloating or abdominal discomfort rather than unnecessarily eliminating large numbers of nutritious foods. Keeping a short food-and-symptom diary can help identify personal triggers.

Spicy foods and chilli-based sauces may worsen burning or abdominal discomfort in people with gastritis or ulcer symptoms, potentially worsening symptoms because they can increase stomach acid or stimulate gastric acid and may aggravate acid reflux. They do not cause H. pylori, but avoiding them temporarily can make meals more comfortable if they are personal triggers.

Citrus fruits, citrus juices and tomato-based foods can also aggravate symptoms in some people because of their acidity. You do not necessarily need to eliminate all fruit or vegetables; instead, choose lower-acid options when symptoms are active, and sour fruits such as lemon and orange are often worth limiting during treatment if they trigger symptoms before you reintroduce foods according to tolerance.

Carbonated and caffeinated soft drinks may also be problematic for some people because of their caffeine, carbonation, acidity or sugar content. If a particular drink consistently causes discomfort, replacing it with water or another non-irritating beverage is reasonable, and avoid eating foods and drinks that repeatedly trigger burning or reflux.

Fried and very fatty foods can be difficult to tolerate when you have upper gastrointestinal symptoms, potentially worsening symptoms by delaying digestion and contributing to stomach inflammation. Choose baked, grilled, steamed or lightly cooked foods instead of deep-fried meals.

Red and processed meats such as bacon, sausages and deli meats are better limited, particularly because fatty meats are harder to digest. If you eat meat, lean red meats or other lower-fat protein choices are often easier to tolerate than heavily seasoned or fried options.

Alcoholic beverages are best avoided during active gastritis, ulcer treatment and H. pylori eradication therapy unless your doctor specifically advises otherwise. They can worsen gastritis symptoms and irritate the stomach lining, and their interaction with particular medicines can vary, so check with your healthcare provider or pharmacist about your prescribed regimen.

Coffee and high-caffeine beverages can worsen upper gastrointestinal symptoms in some individuals, although not everyone needs to eliminate caffeine. If coffee causes burning, nausea, reflux or abdominal discomfort, switch temporarily to a lower-caffeine or caffeine-free alternative and reassess after symptoms settle.

NSAIDs deserve special attention even though they are not foods. Medicines such as ibuprofen and aspirin can contribute to gastric irritation and peptic ulcers, particularly with regular use. Do not stop prescribed aspirin or another medicine without medical advice; ask your doctor whether an alternative or stomach-protective strategy is appropriate.

An H. pylori infection diet and a general gastritis diet plan share many practical principles, including choosing foods that are easy to tolerate and limiting foods that aggravate symptoms.

The key difference is that an H. pylori diet may additionally emphasise probiotic foods and foods containing compounds that have been investigated for antibacterial or protective effects.

Neither diet should be presented as an alternative to medical treatment. H. pylori infection requires appropriate testing and, when confirmed, an evidence-based eradication regimen prescribed by a healthcare professional.

A general gastritis diet is primarily designed around reducing symptoms and avoiding foods that irritate an inflamed stomach. An H. pylori diet follows those principles but may add probiotic-rich foods and foods such as broccoli sprouts or cranberry products that have been investigated specifically in H. pylori research.

The antibacterial evidence for these foods varies considerably. For example, broccoli sprouts have shown reductions in H. pylori colonisation markers in human research, whereas cranberry evidence suggests possible suppression but does not establish reliable eradication.

Therefore, the most accurate way to describe the H. pylori diet is as a supportive eating pattern during medical treatment, rather than a natural replacement for antibiotics.

Both approaches generally favour smaller, more frequent meals if large meals worsen symptoms, and both emphasize easily digestible foods when symptoms flare.

Choose lower-fat cooking methods such as steaming, baking, poaching or grilling; using moderate amounts of healthy fats such as olive oil for cooking is usually preferable to deep-frying, and avoid heavily spiced or acidic foods when they trigger discomfort.

Eating slowly and stopping before becoming excessively full can also make meals easier to tolerate. If you experience reflux or upper abdominal discomfort, avoid lying down immediately after eating and discuss persistent symptoms with your healthcare professional.

A H. pylori diet menu should prioritise foods that are nutritious, minimally processed and personally well tolerated. The following plan is a general template rather than a therapeutic prescription and can be modified according to vegetarian preferences, allergies, diabetes, lactose intolerance and other dietary requirements.

The menu uses foods from the recommended categories while limiting common irritants. If a listed food causes symptoms, replace it with another food from the same nutritional group rather than forcing yourself to eat it.

A typical day could begin with oatmeal cooked in low-fat milk or water, topped with banana and a small amount of nuts if tolerated, with ginger tea as an optional soothing drink if nausea is present. Lunch might include grilled chicken or fish as white meats and fish that are often easier to digest, rice or whole grains and cooked vegetables, followed by a plain yoghurt or kefir snack.

Dinner can combine a lean protein with cooked vegetables and a mild carbohydrate such as rice, potatoes or whole-grain roti, using a little olive oil in cooking if needed; these meals focus on high-protein foods that are lower in fat. Broccoli sprouts can be added to meals if tolerated, while water should be the primary beverage.

This plan is intentionally simple because symptom tolerance can change during treatment. It should be adapted with a doctor or registered dietitian if you have an ulcer, significant weight loss, diabetes, kidney disease, food allergies or another medical condition requiring dietary modification.

Probiotics have been studied as an adjunct to H. pylori eradication therapy rather than as a replacement for antibiotics. Meta-analyses suggest that some probiotic preparations may modestly improve eradication rates and reduce adverse gastrointestinal effects, but results vary according to strain, dose, treatment duration and the antibiotic regimen used.

The term “probiotic” covers many different microorganisms, so the specific strain matters. Lactobacillus reuteri, Lactobacillus rhamnosus and Saccharomyces boulardii are among the organisms investigated in H. pylori treatment research.

For example, a meta-analysis of L. reuteri trials found higher eradication rates when it was used as an adjunct to standard treatment, while research on S. boulardii has reported reductions in treatment-associated gastrointestinal adverse effects.

When selecting a supplement, look for the genus, species and strain designation, rather than choosing a product solely because its label says “probiotic”. CFU count is also relevant, but a larger CFU number does not automatically mean a product will work better; the evidence for the specific strain and clinical context is more important.

Probiotics may be taken during or around eradication therapy depending on the product and the advice of your healthcare professional. Their potential role is mainly to support the gut microbiome and reduce antibiotic-associated symptoms such as diarrhoea, nausea or abdominal discomfort. They may also help replenish beneficial bacteria and restore intestinal flora after antibiotic treatment.

Evidence does not support using probiotics alone as a reliable method of eliminating H. pylori. A 2026 meta-analysis found that probiotic monotherapy could reduce colonisation and symptoms but achieved a relatively low overall eradication rate, reinforcing their role as an adjunct rather than standalone therapy.

If you are taking antibiotics, ask your doctor or pharmacist about the appropriate timing and whether a particular probiotic is suitable for you. People who are severely immunocompromised or seriously ill may require additional precautions with certain probiotic products.

Mastic gum, zinc carnosine, deglycyrrhizinated liquorice (DGL) and fish oil are sometimes promoted as supportive supplements for stomach health or H. pylori. However, the evidence for using these supplements as an H. pylori eradication strategy is considerably less established than the evidence for guideline-recommended antibiotic-based treatment. Omega-3 and omega-6 fatty acids may help reduce stomach inflammation, but the evidence is supportive rather than curative.

Supplements can also have drug interactions, contraindications and variable product quality. NIDDK advises discussing dietary supplements and complementary or alternative medicines with a healthcare professional for safety.

Most importantly, do not delay or discontinue prescribed eradication therapy because a supplement appears to improve your symptoms. Feeling better does not necessarily mean that the infection has been eliminated.

Diet is supportive care, not a cure for H. pylori. The ACG recommends treating confirmed infection with an appropriate eradication regimen and completing a test of cure after treatment; current recommendations include testing at least four weeks after antibiotics are completed, with PPIs or PCABs withheld for two weeks beforehand to reduce the risk of a false-negative result.

Seek urgent medical attention for symptoms such as vomiting blood, black or tarry stools, severe or worsening abdominal pain, fainting or significant weakness. Unexplained weight loss, persistent vomiting, difficulty swallowing or ongoing symptoms despite treatment should also prompt medical assessment rather than continued dietary experimentation.

Do not assume that symptom improvement means the infection has gone away. A follow-up urea breath test, stool antigen test or appropriate biopsy-based test can confirm eradication, and persistent infection may require a different treatment regimen.

The best H. pylori diet is not a restrictive “bacteria-killing” diet. It is a stomach-friendly, nutrient-dense eating pattern that can include probiotic foods, vegetables, whole grains, lean proteins and selected foods such as broccoli sprouts or cranberries while limiting personal irritants, alcohol, heavily processed foods and excessive caffeine.

Book your H. pylori test with MyDiagnostics and discuss the results with your doctor to determine the appropriate treatment.

The most important step is to combine dietary support with a doctor-confirmed eradication regimen, follow the prescribed treatment plan from a healthcare provider rather than relying on diet alone, and complete the recommended follow-up test.

Because chronic H. pylori infection is a recognised cause of peptic ulcer disease and a major risk factor for gastric cancer, treating the infection rather than simply managing symptoms is essential.
