Many people experience gastritis due to the foods and substances they ingest that irritate their stomach and digestive tracts. The only way to reverse this is to stop eating these foods and substances. Generally, things like tobacco, alcohol, acidic beverages, and pain relievers like ibuprofen or aspirin, can cause gastritis in people. Eliminating these substances from the body is really important for those who want to eliminate the gastritis. 

Those who suffer from gastritis will also want to avoid foods that are high in fat. The reason why is that foods that are high in fat frequently cause the stomach lining to become inflamed, exacerbating the gastritis. 

It is important to supplement with foods high in fiber and eat foods that have lots of flavanoids. These foods include cranberries, onions, celery, apples, garlic, and tea. The flavonoids can fight the H. pylori bacteria that can cause gastritis.

Frequently individuals will be prescribed medications to help their symptoms. Prilosec is prescribed many times to help individuals with the level of acid in their bodies and then antibiotics are prescribed to deal with the H. pylori bacteria. Antacids may be used to help with indigestion and heartburn, H2 blockers and the like. 

Recommended foods for individuals with gastritis include eating foods high in antioxidants like fruits and vegetables. Particular fruits and vegetables include bell peppers, tomatoes, cherries, blueberries, and squash. Foods high in calcium and B-vitamins are also recommended. These include kale, spinach, whole grains, almonds, beans, and others.

Foods that should be avoided include all refined foods and most specifically foods with sugar. Pasta, white bread, and the like should be eaten sparingly if at all. Foods for gastritis are tofu, cold water fish, or beans instead of red meat for protein. Only healthy oils should be used when cooking, but even those, including olive oil, should be used in moderation. Trans fats should be eliminated completely from the diet. This includes processed and commercially baked foods as well as margarine. Any beverage that could irritate the stomach lining should be avoided including carbonated drinks, coffee, and alcohol.

Gastritis sufferers should also drink at least eight glass of water each day and exercise a minimum of 30 minutes per day five times per week. Sufferers should also take vitamin supplements to address any nutritional deficiencies that might exist including B vitamins, A, E, C, zinc, calcium, magnesium, and selenium. A multivitamin is usually enough to cover these nutritional deficiencies.
