Helicobacter pylori (or H. pylori) infection is one of the most prevalant bacterial infections worldwide and the primary cause of at least 90% of peptic ulcer disease (PUD) cases in the United States. Left untreated, chronic inflammation of the stomach lining due to H. pylori is the strongest risk factor for developing gastric cancer.
Medical treatment with antibiotics and proton pump inhibitors (PPIs) is essential for eradicating an underlying H. pylori infection. However, dietary choices have protective effects against the outcomes of an H. pylori infection, including symptom relief and reduced severity. This article explores how diet and personalized nutrition strategies play a supportive role in treating H. pylori.Β

Understanding H. pylori Infection
H. pylori is a gram-negative, spiral bacterium found in the stomach. H. pylori infection is highly prevalent in developing countries with low socioeconomic status. It is commonly contracted during childhood and transmitted through the fecal-oral and oral-oral routes. It can thrive in the stomach's harsh, acidic environment and cause chronic inflammation of the gastric lining.
An underlying H. pylori infection is often asymptomatic. However, it can present with the following clinical symptoms:
- Indigestion
- Nausea & Vomiting
- Abdominal Pain
- Loss of Appetite
- Unintentional Weight Loss
If left untreated, an active H. pylori infection can quickly progress from gastritis and PUD to gastric cancer or gastric lymphoma. Given the significant risk associated with developing stomach cancer, it is essential to create an effective treatment strategy supported by dietary choices to promote recovery.
Medical Treatment for H. pylori Infection
Conventional treatment of H. pylori infection includes a combination of at least two (2) antibiotics and acid-suppressing medication. Two antibiotics are used at once to prevent antibiotic resistance. Acid-suppressing drugs such as proton pump inhibitors (PPIs) are used concomitantly to reduce the production of stomach acid and increase gastric pH.Β
Lowering the stomach pH is essential for the bactericidal effect of the antibiotics to take effect. This treatment strategy is known as triple therapy, and it aims to increase therapeutic effectiveness and minimize the risk of developing antibiotic resistance.
First-line Therapy of H. pylori
PPI + Clarithromycin + Amoxicillin or Metronidazole + Bismuth Compounds for 14 days
Second-line Therapy of H. pylori (if treatment failure with first-line therapy)
PPI + Tetracycline + Metronidazole + Bismuth Compounds for 14 days
Risks of Treatment
The risk of developing antibiotic resistance is a common challenge when treating an active H. pylori infection, specifically resistance to clarithromycin therapy. It is critical to retest for H. pylori four (4) weeks after completing antibiotics with a urea breath test or stool test to ensure the bacterium has been successfully eradicated.Β
Antibiotics are notorious for disrupting the gut microbiome and causing gastrointestinal distress, such as nausea and diarrhea. Concurrently, using probiotics and modifying our diet can enhance treatment efficacy, reducing side effects and reliance on antibiotics.
How to Use Dietary Interventions for H. pylori Management
Probiotic Foods
Oral administration of antibiotics is associated with gut microbial dysbiosis, which results in diarrhea and gastrointestinal discomfort. Using probiotics in conjunction with antibiotic therapy for H. pylori has significantly reduced the incidence of antibiotic-associated diarrhea.
Consuming probiotic-rich foods during and after antibiotic treatment supports gut health and helps restore healthy gut microbiota disturbed by antibiotics. Probiotics increase the production of anti-inflammatory cytokines, thus reducing inflammation caused by an active H. pylori infection and supporting the healing of the stomach lining.
It is important to supplement our daily diet with various food sources rich in live, active probiotic cultures to increase microbial diversity and replenish our gut microbiome.Β Some examples include:
- Yogurt: 1 cup (8 ounces) daily
- Kefir: 1 cup (8 ounces) daily
- Sauerkraut: 2-3 tablespoons daily
- Kimchi: 2-3 tablespoons daily
- Low-sugar Kombucha: 1 cup (8 ounces) daily
- Pickles: 1-2 pickles daily
Polyphenols and Antioxidant Foods
Polyphenols are bioactive compounds naturally present in colorful plant foods with potent antioxidant and anti-inflammatory properties. H. pylori produces reactive oxygen species (ROS) in the stomach that cause oxidative DNA damage (9) in the stomach lining.Β
Gastric cancer develops due to the DNA damage caused by H. pylori. Polyphenols help protect our body against oxidative stress from inflammation or infectious processes.
Here are some foods known for their rich antioxidant content:
Berries
- Berries are packed with polyphenols, such as flavonoids and anthocyanins, and have strong antioxidant activity to help prevent inflammation.Β
- Berries (commonly blueberries) are also rich in vitamin C, which contributes to a synergistic antioxidant effect.Β
- Polyphenols found in cranberries interfere with H. pylori's ability to adhere to the stomach lining and prevent the progression of the infection.Β
- Eating one cup of fresh berries every day can support the health of the gastric mucosa.
Green Tea
- The major polyphenol in green tea is epigallocatechin-3-gallate (EGCG), with critical antimicrobial and antioxidant properties.Β
- Combining EGCG with antibiotics was shown to significantly increase its antibacterial activity against the growth of H. pylori.Β
- An average cup of green tea contains 50 to 150 mg of polyphenols.Β
- 2 to 3 cups of green tea daily can complement antibiotic therapy for H. pylori and reduce the risk of stomach cancer.
Cruciferous Vegetables
- Cruciferous vegetables such as broccoli, broccoli sprouts, Brussels sprouts, and kale are abundant in sulforaphane β a potent antioxidant with anti-cancer properties.
- Sulforaphanes induce antioxidant enzymes (9) in the stomach and inhibit oxidative damage of the stomach lining by H. pylori.Β
- These vegetables pack a rich nutritional punch, and one cup of cooked or raw cruciferous vegetables can protect the gastric mucosa.
Polyphenols combined with triple therapy have a synergistic effect, allowing the dose of antibiotics to be lowered. They significantly improve the eradication of H. pylori by reducing bacterial colonization and inflammatory damage to the stomach lining.
Food to Avoid
It is vital to manage dietary choices during and after treatment of H. pylori infection to prevent worsening and support healing of the stomach lining. After treatment, the following foods can be reintroduced gradually and monitored for tolerance.
- Spicy Foods, including hot peppers, jalapeΓ±os, and spices/condiments, irritate the stomachβs mucosal lining and worsen an active H. pylori infection.
- High-fat Foods, including fried food and processed meats (including bacon and sausage), slow digestion and increase stomach acid production. A study observed that a high-fat diet can act synergistically with H. pylori infection to promote systemic inflammation and worsen symptoms.
- Alcohol can erode the mucus lining of the stomach and slow down healing during H. Pylori infection. Additionally, alcohol is contraindicated with the use of antibiotics.
- Caffeine increases the production of stomach acid and worsens symptoms of H. Pylori infection.
Nutritional Supplements and Their Efficacy
Vitamin C is a powerful antioxidant and protective against the development of gastric cancer.Β
- Vitamin C supplementation is recommended after completing a standard antibiotic therapy to prevent reinfection with H. pylori.Β
- The recommended vitamin C dosage per day for healthy women is 75 mg per day and for men is 90 mg daily; daily intake should not exceed 2000 mg daily.
Probiotics increase anti-inflammatory cytokines, reduce proinflammatory cytokines, and promote the eradication of H. pylori.Β
- Probiotics can be used as an adjunct therapy within 2 days of the first antibiotic dose to help recolonize the gut microbiota and prevent antibiotic-associated diarrhea.Β
- Typically, strains of Lactobacillus and Saccharomyces can be taken in doses of 1 to 2 x 1010 CFU (10) per day during and after antibiotic therapy.
Zinc-fortified quadruple therapy reduces H. pylori colonization and improves the outcomes of eradication therapy.Β
Monitoring and Evaluation
Patients should consult with a healthcare professional for personalized dietary guidance and assess the impact of their diet on H. pylori infection and treatment outcomes.
Symptom Diaries
- A daily food diary detailing foods consumed with associated symptoms, including bloating, nausea, pain, and other GI issues, can be useful for adjusting dietary strategies.
- The symptom diary should be maintained throughout treatment and 4 weeks after treatment to identify symptom patterns linked to specific foods.
Follow-up Testing
- A non-invasive diagnostic urea breath test or stool antigen test must be performed at least 4 weeks after completing antibiotics and PPIs to confirm successful eradication of H. pylori.
- A positive test result indicates the presence of H. pylori and the need for further treatment.
Clinical Biomarkers
Lab testing can be used post-treatment to monitor inflammatory markers, micronutrient deficiencies, and overall gut health in response to antibiotic therapy and dietary modifications.
- GI-MAP is a comprehensive test used to determine gut microbial imbalances post-antibiotic therapy.
- Micronutrient deficiencies are common with H. pylori infections. A Micronutrient Test can be a useful tool for determining nutritional status and recommending dietary supplementation to boost the bodyβs immune function.
- Inflammatory markers like C-reactive Protein (CRP) can be used to observe reduced inflammation, which indicates healing of the stomach lining and symptom improvement.
