Gastritis and peptic ulcers are conditions both related to inflammation of the stomach and/or duodenum. Peptic ulcers, in particular, are a result of gastritis, H. pylori infection, the use of NSAIDS or corticosteroids, according to Kathleen Mahan and Sylvia Stump, authors of Krause's Food and Nutrition Therapy. While you can take antibiotics to eradicate H. pylori, and antacids to help neutralize gastric acid, nutrition therapy can also be quite effective.
Foods To Avoid
Gastritis and peptic ulcer sufferers should avoid consuming foods that result in significant acid secretions. Alcohol may cause mucosal damage, especially fermented types such as beers and wines, according to Mahan and Stump. You should avoid both if you are symptomatic. Also, though coffee and caffeine have not been proven to cause peptic ulcers, both do stimulate acid secretion; thus, you should avoid both during treatment to be on the safe side. Findings from a study conducted by O'Mahoney, et al., indicated that spices such as chili, cayenne and black pepper increase inflammation; however, tumeric has shown beneficial outcomes in individuals with H. pylori infections. Foods high in protein may also stimulate acid secretions and should be eaten with caution.
Foods to Consume
Foods that contain omega-3 and omega-6 fatty acids have been shown to have a protective effect on damaged mucosal lining. Foods that contain high amounts of these lipids include salmon, olive oil, nuts and seeds. Overall good nutrition also supports a healthy digestive tract. Adequate fruit, vegetable and fiber consumption may help speed the recovery from an H. pylori infection and prevent the development of ulcers. Choose a diet high in whole foods and low in refined products.
Probiotics
Probiotics may be beneficial when suffering from an inflamed stomach or duodenum. According to a study conducted by Hamilton-Miller et al., supplementation of probiotics may be an effective complementary treatment and even a possible route to eradicate of H. pylori if this is the cause of your gastric inflammation.
Meal Frequency
Large meals are a primary cause for discomfort when experiencing gastritis or peptic ulcers. Eating small meals throughout the day will help you better tolerate any symptoms. Timing of meals is also important. Try not to eat within three hours of lying down. Give your stomach a chance to digest its contents before retiring.
