Diet for Gastritis: What to Eat What foods should be avoided? Causes, Treatment and Panorama

There are some forms of this condition that can cause ulcers or increase the risk of cancer.

Gastritis is the main name used for any condition that involves inflammation of the lining of the stomach.

It can be acute (occurs suddenly) or chronic (occurs over time). There are different types of gastritis that are caused by different factors.

For most people, gastritis is mild and will disappear quickly after treatment.

Your diet is important for your digestive and general health. What you put in your stomach can make a difference in the health of your digestive system.

For example, some forms of gastritis are caused by drinking alcohol too often or too much at the same time. Avoiding some foods and drinks and eating others can help control the condition.

What to eat?

There are some foods that can help you control your gastritis and decrease symptoms. These include:

  • Foods rich in fiber such as apples, oats, broccoli, carrots and beans.
  • Low-fat foods such as fish, chicken and turkey breast.
  • Foods with low acidity, or more alkaline, such as vegetables.
  • Drinks that are not carbonated.
  • Drinks without caffeine.
  • Probiotics such as kombucha, yogurt, kimchi and sauerkraut.

Some studies show that probiotics can help with Helicobacter pylori (H. pylori). H. pylori is a bacterium that causes an infection in the digestive system that can cause gastritis or stomach ulcers.

Foods that should be avoided?

Foods to avoid with a gastritis diet:

Foods high in fat can worsen inflammation in the lining of the stomach. Some other foods to avoid because they can irritate the stomach are:

  • Alcohol.
  • Café.
  • Acid foods such as tomatoes and some fruits.
  • Fruit juice.
  • Fatty foods.
  • Fried food.
  • Carbonated drinks.
  • Spicy food.
  • Allergenic or symptomatic foods.


Gastritis diet with an ulcer:

Some types of gastritis can eventually cause an ulcer. If you have an ulcer, the type of diet you should take is similar to that of gastritis.

With an ulcer, you should make sure you have a diet rich in vitamins. A healthy diet with foods full of vitamins facilitates the healing of the ulcer.

You can also talk to your doctor about eliminating milk from your diet, even if it seems to reduce the pain of the ulcer. Actually, it can make the pain worse later.


The types of gastritis have different causes. Some of these include:

Injury or serious illness:

The main diseases or injuries can cause gastritis due to acute stress. A lesion in the body (not necessarily in the stomach) or a disease that affects blood flow to the stomach increases the acid in the stomach.

Damage to the stomach lining:

This damage can be caused by some of the following factors:

  • Consumption of alcohol and various drugs.
  • Aspirin and analgesics such as NSAIDs.
  • Swallowing a corrosive substance.
  • Bacterial or viral infections.
  • Radioactive treatments in the upper part of the abdomen or the lower part of the thorax.
  • Surgery to remove part of your stomach.

An infection caused by Helicobacter pylori (H. pylori):

This bacterium is one that causes infection. H. pylori is the most common cause of gastritis. And it is more common in less developed countries. It usually starts when you are a child.

Autoimmune disease:

Autoimmune diseases can also contribute to gastritis. This can occur when the immune system goes in search of your body’s own healthy tissue in the lining of the stomach.

Food allergies:

The evidence suggests in those who have eosinophilic esophagitis (EoE) (a gastrointestinal disorder) that the ingestion of allergenic foods can trigger gastritis. It is important that you work with your doctor or board certified allergist to determine any food allergies.


Gastritis is treated with medications that include antacids. For gastritis caused by H. pylori, your doctor will also prescribe antibiotics.

You should also avoid taking anything that causes gastritis, such as alcohol, aspirin, or pain killers. Supplemental probiotics can also be useful to control gastritis and prevent future episodes.


The amount of time your gastritis will last to start treatment depends on the type, cause and severity.

Most of the time it will improve in a short time after starting treatment. Be sure to talk to your doctor before changing your diet or stopping or starting new medications, including those that are sold without a prescription.
