Approximately 20 million Americans will suffer from an ulcer once during their lifetime, according to the Cleveland Clinic. The foods you eat will not cause an ulcer but they can cause increased stomach acid production and slow down the healing process. If you have an ulcer, avoid consuming foods and beverages that increase stomach acid production.
Mucus Layer Function
Ulcers are the result of damage to the thick mucus layer that protects the lining of the digestive tract. Your esophagus, stomach and the first part of your intestine, called the duodenum, make up your digestive tract. When the mucus layer suffers damage, digestive juices known as hydrochloric acid and pepsin make contact with the lining, causing ulcers to form. Choosing foods that do not increase the production of stomach acids can help your ulcer heal.
Ulcer Causes
The main cause of damage to the mucus layer is a bacterial infection called Helicobacter pylori, also called H. pylori. The likely causes of H. pylori include foods and beverages that are unclean and mouth-to-mouth contact. The other major cause of damage to the mucus layer is the use of nonsteroidal anti-inflammatory medications including aspirin, ibuprofen and naproxen.
Foods to Enjoy
Eat foods such as cereal, crackers, bread, rice, pasta, potatoes, peanut butter, apples, peaches, pears, bananas, berries, grapes and kiwi. Consume lean meats including poultry and seafood and eat tofu, low-fat soups and dairy products that are either low-fat or fat-free. Drink beverages including apple juice, grape juice, herbal teas and decaffeinated sodas.
Foods to Eliminate
Avoid consuming pepper, chili powder, cloves, cinnamon, salsa, hot or spicy marinades, chocolate and pickled foods. Do not eat hot peppers, tomatoes and tomato-based products, citrus fruits, vegetable or citrus juices, peppermint, onions, garlic, chocolate, greasy or fried foods and fatty meats. In addition, do not drink alcoholic beverages or caffeinated products including coffee, tea and soda.
Prevention
Wash your hands before eating and after using the bathroom to prevent contracting H. pylori. Take nonsteroidal anti-inflammatories with food or ask your doctor about alternative medication choices.
Warnings
Do not eat or drink any foods that cause stomach pain, burning in your esophagus or any other stomach discomfort. In addition, if you experience black or bloody stools, vomit that is bloody or resembles coffee grounds or sudden sharp abdominal pain, call your doctor immediately. These symptoms could mean that your ulcer is getting worse.
