Foods to avoid when treating H pylori and its symptoms

Although your doctor probably won’t discuss this topic with you, there are some foods to avoid when treating H pylori.

These foods can have a negative impact on your H pylori treatment and may even cause similar symptoms to H pylori infections.

If you do not avoid these foods, you may find that your H pylori treatment doesn’t work, or that it does work but your symptoms remain.

Food can cause the same symptoms as H pylori

Certain foods can cause inflammation in your stomach and intestine in much the same way H pylori does.

Inflammation is raw, swollen, red, hot tissue that typically causes the burning, aching or gnawing pain you experience when you have heartburn, acid reflux and a sore stomach.

If you do not reduce and eliminate digestive inflammation, your symptoms will most likely remain, even if you safely eradicate H pylori.

Unfortunately, many foods that are eaten on a daily basis by people can trigger inflammation, making your digestive system feel unsettle, painful and bloated.

These foods and ingredients include gluten, coffee, cow’s milk, soy, sugar, spices, tomatoes, onions, garlic and even raw green vegetables.

Here is a list of foods to avoid when treating H pylori

H pylori and Gluten

Gluten is found in wheat, rye, barley and other commonly eaten grains; it is NOT contained in organic oats, rice millet and buckwheat. Avoiding gluten means cutting out your regular bread, crackers, biscuits, pizzas, cereals, pasta, beer/lager and other popular foods.

Gluten can cause major symptoms and in my opinion should not be eaten by anyone, irrespective of whether they have H pylori or not. It can irritate the small intestine and cause all the same symptoms as H pylori, and more.

Digestive inflammation caused by gluten can perpetuate symptoms even when H pylori has been eradicated, and it can even prevent you from eradicating H pylori in the first place. Avoid at all costs!

Cow’s Milk

Cow’s milk can cause stomach inflammation in the same way as H pylori can. It can also trigger lactose intolerance and casein allergies, which can end up causing similar symptoms to the ones caused by H pylori.


Soy is not digested well by some people and can irritate your digestive system big time. Traditionally fermented soy such as tempeh, miso and natto may be ok.

H pylori and Coffee

Coffee can trigger heartburn and acid reflux, similar to the symptoms caused by H pylori.

Onions, Garlic and Tomatoes

These otherwise healthy options can, in some people, trigger similar symptoms to H pylori (especially heartburn and reflux).

However, garlic has been shown to kill H pylori, so it is worth experimenting to see if it is affecting your symptoms in any way. If not, eating it will probably be of benefit.

Sugar and Processed Grains

The bacteria and fungi that are part of your microbiome can fall out of balance if you eat too much sugar and processed flour.

Candida albicans and other bad bugs can overgrow if you eat too much sugar, leading to the H pylori symptoms you are trying to overcome.

Fizzy Drinks

The ‘fizz’ in fizzy drinks can irritate your stomach in the same way as H pylori, so these beverages are best avoided.

Spices and Vinegar

Spices such as chilli are often best avoided because they can irritate your stomach lining.

Raw Green Vegetables

Contrary to popular belief, raw green veggies such as broccoli and kale are not always wise choices.

When they are raw or undercooked, these veggies are hard to digest and can contribute to bloating, gas and loose stools.

They also contain high levels of oxalates, which in sensitive people can cause serious problems.

H pylori and Alcohol

A list of foods to avoid when treating H pylori would not be complete without mentioning alcohol.

Alcohol is an irritant to the digestive system and on its own is associated with stomach ulcers and cancer. Of course, it also interacts in a bad way with antibiotics.

Thus, I recommend you completely avoid alcohol when treating your H pylori infection.

What can you eat instead?

When choosing a list of foods to avoid when treating H pylori, it is important to know what your alternatives are.

It’s no good someone like me telling you to avoid certain foods if you do not know what to eat instead.

That’s why I wrote The H Pylori Diet. It’s a simple book that teaches you which specific foods to avoid and which ones to eat instead.

It contains recipes, meal planners, preparation guidelines and other helpful tools to help you seamlessly transition to a digestive-friendly diet.

If you want to avoid taking antibiotics, the book also teaches you specific cleansing protocols to fight H pylori, Candida and restore your friendly bacteria levels.

Anyway, I hope this helps and look forward to hearing about your progress.
