Foods to Avoid With PUD

Peptic ulcer disease is a condition characterized by open sores, or ulcers, that form on the inner lining of your stomach, esophagus or upper intestine. About 20 million people in the United States suffer from peptic ulcers, according to the University of Maryland Medical Center. Peptic ulcer disease is typically caused by Helicobacter pylori bacteria, although taking aspirin or non-steroidal inflammatory drugs may also cause ulcers. Avoiding certain foods may help to reduce the pain, nausea and heartburn associated with peptic ulcer disease.

Check with your doctor before changing your diet to address peptic ulcer symptoms. Diet should not replace conventional medical treatment for peptic ulcer disease.

Fried Foods

Foods that are fried in oil, such as potatoes, meats and vegetables, may aggravate peptic ulcers and produce abdominal pain and heartburn, according to Dr. James Balch and Phyllis Balch, authors of "Prescription for Nutritional Healing." Stay away from fast food offerings such as breaded fish patties, fried chicken, onion rings and french fries -- these foods are typically fried in trans-fatty oils, which may cause greater discomfort than foods fried in olive oil or natural, non-hydrogenated vegetable oils.

Cow's Milk

Cow's milk contains casein, saturated fats and animal proteins. These components of cow's milk may stimulate the production of hydrochloric acid in your stomach. Although hydrochloric acid is necessary for the breakdown of foods and the assimilation of nutrients, elevated levels of this acid may irritate peptic ulcers, according to the Balches. Cheese, yogurt, sour cream and cottage cheese may similarly worsen the symptoms of peptic ulcer disease.

Spicy Foods

Highly-spiced foods do not cause peptic ulcers, according to the University of Maryland Medical Center. However, once peptic ulcers have formed on the lining of your esophagus or digestive system, they may aggravate these open sores. Avoid foods spiced with hot peppers such as jalapenos, cayenne peppers, serranos or habaneros. These peppers contain capsaicin, a heat-producing chemical compound that can worsen pain and other symptoms of peptic ulcer disease. Black pepper and ginger may cause similar discomfort.
