what foods kill h pylori

Helicobacter pylori (H. pylori) is a bacterial pathogen linked to an array of gastrointestinal tract conditions.

Surprisingly, this bacteria has colonized the digestive systems of over half the world’s population. Starting from abdominal discomfort, ulcers, heartburn, and gastritis, to issues as serious as peptic disease, MALT lymphoma, or gastric cancer, could all be caused by the colonization of this bacterium. 

However, the good news is that there are foods that can effectively treat H. pylori. You must certainly be eager to know what foods kill H. pylori. In this blog, we’re going to cover all the foods that can help treat H. pylori as well as foods that should be avoided.

Following the H. pylori diet as mentioned below could help you treat the bacteria naturally. At the same time, it would also complement your treatment plan, if you’re following any.

Let’s start with understanding the bacterium first.

What Is H. pylori?

Helicobacter pylori is a gram-negative, spiral bacterium that’s often found in the stomach. This bacterium attacks the stomach lining and is responsible for most small intestinal and stomach ulcers.

H. pylori is capable of surviving in the hard acidic environment of the stomach as it can reduce the acidity in its surroundings. This flagellated bacteria (meaning it has a little tail that helps it move on its own) is also capable of hiding from the immune system and is usually resistant to multiple agents.

This is because the bacteria penetrate the stomach lining and make themselves unreachable by the immune cells. Well, that’s what makes H. pylori a pathogen difficult to treat.

How Can You Tell if You Have It?

In order to confirm whether you’re infected with H. pylori or not, you need to undergo a test for the same. There are different test options available, such as stool tests, blood tests, and breath tests to detect this bacterium’s presence in the body.

If its presence is confirmed, you’re recommended to follow the treatment suggested by your healthcare practitioner. Along with this, there are foods that can support the whole process and help kill H. pylori naturally.

Foods With Anti-H. pylori Action Property

There are several foods with research-based anti-helicobacter pylori activities. If you have been searching for how to treat h pylori naturally, then here are some of these foods having anti-H. pylori properties for you:


Probiotics are well-known for their amazing benefits on digestive and overall health. By increasing the population of good bacteria in our gut, probiotics help fight bad bacteria such as H. pylori.

Taking probiotics-rich foods such as yogurt, sauerkraut, kefir, etc., you can also reduce the side effects (such as poor digestion, constipation, and diarrhea) caused during H. pylori antibiotic treatment.

Furthermore, the presence of H. pylori also influences the PH of the stomach, which in turn can influence the gut flora. An unbalanced gut flora could further give rise to a lot of digestive and overall health issues. Thus, it’s important to add a probiotic to your diet.

Besides foods, you can also choose a good probiotic supplement like Optimal Health Gut Solution for better digestive health and support the body’s fight against H. pylori.

Isothiocyanates, in particular sulforaphane, have been researched to be very potent in treating H. pylori. Thus, adding these cruciferous vegetables to the diet is highly beneficial.

These three veggies are also easy to digest hence reducing gastric pain that can be caused during the H. pylori treatment.

Sauerkraut juice and broccoli sprouts are also rich sources of sulforaphane.

Black Cumin Seed

Black cumin seed, or Nigella Sativa, is beneficial for various diseases such as diabetes, cardiovascular illnesses, mental disorders, inflammatory conditions, and even cancer.

Thymoquinone is the main active component of Nigella Sativa that gives these seeds their amazing medicinal properties.

Thymoquinone is also found to have an anti-H. pylori action. It’s also effective in fighting fungal, viral, and parasitic infections. The black cumin seed oil has been clinically approved to treat H. pylori symptoms.


Turmeric is a popular Indian spice used for ages in Ayurveda due to its excellent antioxidant, anti-inflammatory, antitumor, antibacterial, and antiapoptotic effects.

Curcumin, found in turmeric, is a major polyphenolic constituent that has also been found to inhibit the growth of H. pylori.

Cranberry Juice

Cranberries have been found to inhibit the growth of H. pylori and have a cytotoxic effect against them. This is due to the fact that cranberries are a polyphenol-rich fruit. It’s suggested that the growth inhibitory effect of cranberry juice over H. pylori is due to the polyphenol component.

Cranberry Juice

Cranberries also contain proanthocyanidins, said to be effective in killing this pathogen. Furthermore, cranberries inhibit the adhesion of H. pylori to the gastric mucus.

Thus, drinking cranberry juice daily could help greatly in eliminating H. pylori from the body. But make sure to avoid added sugar and additives.

Other berries suggested for suppressing H. pylori growth are strawberry, bilberry, raspberry, blueberry, and raspberry.

Muscadine Grapes

Due to the high concentration of anthocyanin and flavonoids, muscadine grapes possess anti-H. pylori activities.

The active polyphenols found in muscadine grapes are resveratrol and quercetin, which are natural antioxidants with a wide range of benefits. Quercetin in the muscadine grape skin was found to inhibit H. pylori and reduce inflammatory cytokines in mice.


In a study, it was found that low concentrations of zinc in gastric mucosa can increase the severity of H. pylori-related inflammation.

This means a zinc deficiency in patients with H. pylori infection can make the situation worse. Thus, adding zinc-rich foods is important in order to inhibit the growth of H. pylori and inflammation in H. pylori-induced gastritis. Foods that are rich in zinc include:

  • Nuts
  • Kale
  • Beans
  • Garlic
  • Lentils
  • Spinach
  • Broccoli
  • Chickpeas
  • Mushrooms
  • Whole grains
  • Citrus fruits (lemon, grapefruits, guava, orange, and kiwi)

Vitamin C & Iron

Researchers have found that low levels of vital metals like iron and vitamins (such as vitamin C), which are essential for the body, also contribute to increasing the severity of H. pylori infections.

A study was also conducted to find the association of H. pylori infection with anemia. The results concluded that there was a high prevalence of anemia in participants having H. pylori infection and intestinal parasitic infection.

Apart from this, there are several studies that show that high levels of vitamin C are effective in inhibiting the colonization of H. pylori.

Healthy Oils

Healthy oils such as omega-2, omega-6, black currant seed oil, and PUFAs are shown to prevent the growth of H. pylori. This is because healthy oils reduce inflammation and heal the lining of the gut.

Other healthy oils include grapefruit seed oil, carrot seed oil, fish oil, and extra virgin olive oil.


Watermelons are said to be good at treating ulcers. One recent animal study conducted on mice to find the relationship between watermelon and H. pylori found some positive potential. The results of the study showed that watermelon helped reduce the levels of H. pylori by up to 50%.

This means if you’re struggling with symptoms of H. pylori such as ulcers then eating plenty of watermelons could give you some relief.

Foods To Avoid

Just like there are some foods that hinder the growth and colonization of H. pylori, there are also foods that can support this bacteria’s growth.

By disturbing the viscosity and integrity of the gastric mucosa, these foods contribute to increased H. pylori-induced inflammation. This can result in peptic ulcers, malignancy, suppressed immunity, abnormal metabolism, and more.

So, what foods to avoid with h-pylori infection? Here are a bunch of them:


Eating a lot of sugary foods can weaken the immune system, which can increase or worsen the symptoms of H. pylori infection.

One study shows that higher levels of glucose enhance H. pylori adhesion. In another finding, scientists discovered that H. pylori uses sugar to trick the immune system. Therefore, it makes sense to limit the intake of sugar while on an H. pylori diet.


Alcohol makes the stomach produce more acid. Drinking excess amounts of alcohol can increase stomach inflammation, making the situation even worse.

Caffeinated Drinks

Caffeine is said to stimulate stomach movement and increase the production of stomach acid which can cause further irritation.

More stomach acid production can also increase the risk of ulcers and worsen symptoms. Thus, the consumption of coffee, black tea, chocolate, or any caffeinated drink should be avoided.

Fatty Foods

Foods rich in fat, such as fatty meats, yellow cheeses, or fried foods, are hard to digest. These foods also stay in the stomach a little longer than usual due to difficulty in digestion.

Spicy or Processed Foods

Spicy foods such as garlic sauce, jalapeno, salsa, cayenne peppers, soy sauce, or spicy mustard can cause heartburn or irritate the stomach, and thus should be avoided.

red and green chili

Processed or canned foods contain chemical additives and preservatives that can increase inflammation as well as irritate the stomach or intestine.

What Can I Drink To Get Rid of H. pylori?

Green Tea: As green tea is loaded with antioxidants and nutrients thus it’s supposed to possess anti-H. pylori activity. In one animal study, it was found that this healthy beverage can decrease the inflammation and colonization of H. pylori.

Honey: There are some studies that show that honey has anti-H. pylori activity. Honey can suppress the bacteria’s growth in the gastric epithelial cells. Thus, adding honey to all your healthy drinks could prove to be highly beneficial.

*Adding manuka honey to your daily cup of green tea is also a great idea to get rid of H. pylori infection.

Cranberry Juice: Research has found that cranberries (which are loaded with polyphenols) are effective in inhibiting the growth of H. Pylori. Therefore, drinking cranberry juice daily can ward off the risk of H. pylori infection, or can reduce or even eradicate it completely.

Turmeric Milk: Turmeric inhibits the growth of H. pylori due to the presence of the phenolic compound curcumin. Drinking turmeric milk can help fight inflammation as well as prevent bacteria from entering and damaging gastric cells.

Ginger Drink: Ginger contains phenolic compounds (6-gingerol, 10-gingerol, 8-gingerol, and phenolic acids) which give ginger its anti-H. pylori properties. Making a ginger drink in warm water can help treat H. pylori infection.

What Causes H. pylori to Flare Up?

H. pylori bacteria are passed from one person to another through direct contact with saliva, stool, or vomit. Kissing, oral sex, or bad hygiene could likely be the cause of such a spread.

Besides this, contaminated food or water also contributes to the spread of this bacterium, especially in developing countries.

Hence, it’s important to drink clean water and use clean water for preparing food. Besides this, maintaining proper hygiene habits like washing hands thoroughly after using the toilet is also crucial to eliminate the risks of such harmful bacteria.

Does Sugar Make H. Pylori Worse?

Yes, sugar can make an H. pylori infection worse. In this study, it was found that higher levels of glucose can enhance the adhesion and virulence of H. pylori.

This study also says that people with H. pylori infection and high blood sugar levels (hyperglycemia) are at a high risk of gastric cancer. This is because high glucose levels could increase the permeability of endothelial cells and cancer-related signaling.

This means that high sugar can facilitate H. pylori enhancement by providing favorable conditions for its growth.

Thus, avoiding excess sugar consumption is good during the treatment of H. pylori infection or in general. As we all know too much consumption of sugar is also associated with a lot of health concerns.

How Can One Tell When H. Pylori Is Gone?

In order to tell that your H. pylori infection is completely gone, you need to undergo a lab test. It’s most likely that your doctor will ask you to undergo a stool or breathing test after about two weeks to four weeks of finishing the medication.

If the test shows the presence of the bacteria, then the antibiotic treatment would continue. If the test comes negative then that tells that you’re free of H. pylori infection.


Overall, we can conclude that diet has an undeniable impact on H. pylori colonization. An H. pylori diet like the one mentioned above can help get this bacterial infection under control.

Eating healthy foods rich in polyphenols, zinc, vitamins, iron, and other components with anti-H. pylori activities will also complement the treatment recommended by your doctor. Also, you can rest assured of no adverse effects as making dietary changes is an all-natural way to treat H. pylori.

Besides this, you can also try to increase the population of some beneficial bacteria like Akkermansia muciniphila in your gut. This bacteria can help you maintain a healthy gut microbiome and protect you from diseases like H. pylori.

Moreover, this bacteria also maintains healthy intestinal barrier function, reduces low-grade inflammation in the gut, and can control gut permeability. Here is how to increase akkermansia muciniphila in your gut.
