What foods soothe an ulcer?

Ulcers can be an incredibly painful condition, often making it difficult to enjoy meals. While there is no specific “ulcer diet,” choosing the right foods can help soothe irritation and promote healing. This article explores the best and worst foods for ulcers, with tips on how to modify your diet to find relief.

What is an Ulcer?

An ulcer is an open sore that develops on the lining of the stomach (gastric ulcer) or small intestine (duodenal ulcer). Ulcers form when there is an imbalance between digestive juices in the stomach and gut protection/repair mechanisms. The most common causes are:

  • Infection with Helicobacter pylori (H. pylori) bacteria
  • Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen
  • Excessive alcohol consumption
  • Smoking
  • High stress levels

The most common symptom of an ulcer is a burning pain in the stomach area between meals or during the night. Other symptoms can include:

  • Bloating
  • Nausea
  • Poor appetite
  • Unexplained weight loss

Left untreated, ulcers can lead to internal bleeding and increase the risk of stomach cancer. Medications can help control acid production and kill H. pylori bacteria. However, diet also plays an important role.

Best Foods for Ulcers

Certain foods may help relieve ulcer symptoms and promote healing by decreasing stomach acid production, protecting the stomach lining, and reducing inflammation. Beneficial options include:

Fiber-Rich Foods

Fiber forms a thick gel in the intestines that helps capture toxins and speed digestion, preventing them from aggravating an ulcer. Good sources include oatmeal, pearled barley, whole-grain breads and cereals, beans, peas, lentils, berries, and ground flaxseeds.

Leafy Greens

Vegetables including kale, spinach, romaine lettuce, and broccoli are high in folate, which helps repair damaged tissues in the GI tract. They also contain antioxidants that help reduce inflammation.


Garlic has antioxidant and antimicrobial effects that may inhibit H. pylori and protect the stomach lining. Adding fresh garlic to cooking daily or taking garlic supplements can help speed ulcer healing.


Studies show that raw Manuka honey displays antibacterial effects against H. pylori and may protect and coat the stomach lining to promote healing. Mix 1-2 teaspoons into tea, smoothies, or oatmeal.


Probiotic supplements and fermented foods like yogurt contain beneficial gut bacteria that can help normalize acid levels and reduce inflammation in the GI tract. Look for options with multiple strains like Lactobacillus and Bifidobacterium.

Marshmallow Root

Marshmallow root contains mucilage that forms a protective barrier on the stomach lining. Herbal teas, tinctures, or supplements may help soothe ulcer pain and inflammation.

Worst Foods for Ulcers

Certain foods may aggravate ulcer pain and delay healing. Foods linked to increased stomach acid production and GI irritation include:

Coffee and Caffeinated Beverages

Coffee, tea, soda, and energy drinks containing caffeine may stimulate acid secretion and dehydrate the body. Limit to 1-2 cups per day and avoid within 1-2 hours of bedtime. Opt for decaffeinated varieties and herbal teas.


All types of alcohol can irritate the stomach lining. Avoid drinking alcohol when you have an active ulcer.

Citrus Fruits and Juices

Oranges, lemons, grapefruits, and other citrus contain acidic juice that can aggravate ulcers. Limit citrus fruits and switch to lower-acid options like melons, apples, and bananas.


Raw tomatoes and tomato-based products like ketchup, pasta sauce, and salsa also have an acidic pH. Choose cooked or stewed tomatoes which are gentler on the stomach.

Spicy Foods

Heavily spiced foods like hot sauce, chili, curries, and peppers may irritate the stomach lining. Limit added spices and opt for blander dishes until your ulcer heals.

Fatty and Fried Foods

High-fat foods like fatty meats, whole milk dairy, fast food, and fried items take longer to digest, increasing stomach acidity. Choose leaner proteins, low-fat dairy, and bake or grill instead of frying.

Food Reason to Avoid
Coffee and caffeinated beverages Stimulate acid production and dehydrate the body
Alcohol Irritates the stomach lining
Citrus fruits and juices Contains acidic juice that aggravates ulcers
Tomatoes Have an acidic pH, especially when raw
Spicy foods Can irritate the stomach lining
Fatty and fried foods Take longer to digest, increasing stomach acid

Tips for an Ulcer-Friendly Diet

Other suggestions to help manage ulcer symptoms through diet include:

  • Eat smaller, more frequent meals – Large volumes of food and infrequent meals increase acid production. Try eating 5-6 smaller meals spread throughout the day.
  • Avoid eating 2-3 hours before bed – Lying down soon after eating makes it easier for stomach acid to back up into the esophagus, exacerbating ulcer pain.
  • Chew foods thoroughly – Digestion begins in the mouth. Take time to chew each bite 20-30 times to ease the burden on your stomach.
  • Limit milk – While dairy can help buffer stomach acid temporarily, the proteins also stimulate increased acid production. Limit milk and opt for nondairy alternatives.
  • Avoid NSAIDs – Over-the-counter painkillers like aspirin and ibuprofen can worsen ulcers. Acetaminophen is a safer option for pain relief.
  • Quit smoking – Smoking impairs the stomach’s protective lining. Quitting tobacco use is essential for ulcer healing.

Making dietary changes can significantly ease ulcer symptoms and promote healing. However, severe or persistent ulcers may also require medication to eradicate H. pylori infection or suppress acid production. Work with your doctor to develop an integrated treatment plan tailored to your needs.

The Bottom Line

Ulcers can be extremely uncomfortable, but adjusting your diet by adding stomach-soothing foods and avoiding potential irritants can aid healing. Focus on high-fiber whole grains, fruits, vegetables, lean proteins, probiotics, garlic, honey, and marshmallow root. Limit coffee, alcohol, citrus, tomatoes, spices, and fatty foods. Smaller, more frequent meals are also beneficial. With proper treatment and key dietary changes, most ulcers can fully heal within a few weeks.
