Spicy and Acidic Foods
Managing acid reflux is important because it is related to stomach ulcers. Avoid spicy foods, such as chilies, hot peppers and hot sauce. These foods can increase stomach acid, trigger acid reflux and worsen symptoms associated with stomach ulcers.
The 1991 study from the “Medical Clinics of North America” also determined that foods high in citric acid caused discomfort in some patients with stomach ulcers. Citric acid can be found in lemons, limes, oranges, grapefruits, pineapples, fruit juices, jams and jellies.
Creamy foods
Rich, high-fat condiments and sauces, like mayonnaise or Alfredo sauce, can sometimes trigger ulcer symptoms. Some people report problems with peanut butter, which is rich in healthy fats, too.
Soda
Cola and other carbonated beverages pack a double whammy: Not only do most contain caffeine and sugar or artificial sweeteners, which can increase gas and bowel production, but the bubbles can also cause cramping and make you feel bloated.
Chocolate
Sugar and caffeine, two of chocolate’s most prominent ingredients, can both contribute to cramping and increase stool frequency in people with ulcer, especially during a flare-up.
Seeds
If you are having an ulcer flare-up, avoid eating whole seeds. It helps if you even steer clear of the tiny fruit seeds (such as those found in berries) in the fruit itself, as well as in smoothies, jams, and yogurts made with real fruit.
Seeds are generally not a problem, though, if they’re ground finely enough, Cepo says. Her patients have never had issues with ground flaxseed, for example, or tahini, which is made from a sesame-seed paste.
