An ulcer is an open wound in your digestive track, and often occur in the part of your small intestine called the duodenum; however, ulcers may also form in your stomach -- these are called gastric or stress ulcers. Contrary to popular belief, ulcers are caused by a bacterial infection, not stress; however, stress can irritate an ulcer, as can certain foods. This can be avoided by maintaining a special diet.
Flavonoids
Helicobacter pylori are bacteria that cause most ulcers by attacking the lining of the stomach which protects it from the damage caused by digestive juices. The spread of H. pylori may be inhibited by flavonoids. Flavonoids are organic compounds found in most plants that give fruits and vegetables their color. Their antioxidant and anti-secretory properties protect the stomach lining and aid in the healing of gastric ulcers, according to the article "Flavonoids with Gastroprotective Activity," published in the March 2009 issue of "Molecules." Apples, cranberries, celery and onions are high in flavonoids.
Meals
Small meals are preferred since large meals require more stomach acid in order to digest the food properly; however, dividing your food intake into six meals instead of three is problematic as well because eating too frequently can increase the amount of acid in your stomach, according to Drugs.com. To maintain some consistency in the production of stomach acid, it may be better to eat moderately sized meals at regular intervals on a daily basis.
What to Avoid
Stomach acid can aggravate an existing ulcer causing increased bloating and pain. Foods that produce a lot of stomach acid should be avoided, such as foods high in sodium. A good way to reduce salt intake is to avoid canned, packaged and processed foods that contain a lot of sodium and preservatives. Stomach acid is also increased by drinking certain beverages, such as coffee, alcohol and carbonated drinks such as soda. Spicy foods such as peppers and chili can also irritate your stomach if you have an ulcer.
Fiber
Eating foods high in fiber is unlikely to exacerbate stomach pain. In fact, committing to a high-fiber diet can speed your recovery from an ulcer and prevent ulcers from occurring, according to the University of Maryland Medical Center. Although fiber can be consumed by eating whole grain breads, cereals and pastas or by taking supplements, fruits and vegetables are especially good sources of fiber if you have or are prone to ulcers.
