Good ulcer foods. So, is there any food that will not cause irritation to the ulcer? Thankfully the answer to that is yes. There are a lot of foods that you can eat with very little likelihood of them causing you discomfort. In fact, some of these foods might even aid in the healing of the ulcer. The key is to eat whole foods that are packed with nutrients while avoiding processed and fatty foods. Some of these foods include whole grains, low-fat products, lean meats, fruit-except for citrus, leafy greens, foods that are rich in probiotics like yogurt, kombucha, and sauerkraut, olive oil, berries, broccoli, cauliflower, and cabbage.
