Stomach ulcers are usually treated with antibiotics, but a healthy diet is important for speeding up recovery from a stomach ulcer and making the symptoms more tolerable, according to Healthline. Fried and fatty foods can irritate the stomach ulcer and lower the effectiveness of the immune system.
Fruits, vegetables and whole grains are dietary choices that help heal a stomach ulcer, reports Healthline. In addition, deglycyrrhizinated licorice may help stomach ulcers heal faster. Individuals suffering from a stomach ulcer should avoid carbonated beverages, spicy food, foods high in sugar, processed foods and salty red meat. Additionally, coffee, including decaf, can make a stomach ulcer worse.
