This post was written by Margaret Ojeniyi and edited by Lani Sodunke.

Ulcer is the inflammation of the stomach, oesophagus, or intestine lining that affects both the young and old. Ulcer is caused by long-term use of non-steroidal inflammatory medicines (NSAIDs) and a bacterial called Helicobacter Pylori (H. pylori).

Ulcer episodes happen when acids from food eaten causes damage to the stomach walls. Some of the symptoms of ulcer include:

  • Indigestion
  • Abdominal pain
  • Back pain
  • Unexplained weight loss
  • Heartburn, due to acid reflux
  • Bloating 
  • Flatulence and belching
  • Feeling full
  • Stooling and vomiting

Untreated ulcer can lead to persistent pain, bleeding, and life-threatening stomach cancer risk. However, speaking with a medical expert and following ulcer friendly diet can go a long way to relieve the symptoms and make you feel better.

The Best Nigerian Foods to Eat if you Have Ulcer

Studies have shown that anti-inflammatory food or food rich in antioxidants can help manage the symptoms of an ulcer. Whether you believe it or not, there are ulcer friendly Nigerian foods such as:

1. Vegetables and Non-acidic Fruits:

Vegetables are good for anyone with ulcer. Vegetables like spinach and kale contain Vitamin A, and they increase mucus production in your gastrointestinal tract, which is believed to help manage ulcers. Also, jute leaf, commonly known as Ewedu in Nigeria has been found to have antacid activity, which makes it effective in the management of acidity and ulcer.

Fruits like apple, watermelon, and berries (strawberry, cranberry, and cherry) have been beneficial in reducing H. pylori infection. Other vegetables for ulcer patients include: cabbage, carrot, green pepper, okra, etc.

2. Plantain

Unripe plantain is beneficial to individuals suffering from ulcer and other gastrointestinal tract diseases. It can be boiled or made as porridge. However, if you have an ulcer, you should be mindful of fried plantain and other fried foods.

3. Probiotics (yogurt, kimchi)

Taking probiotics like yogurt or supplements can help natural balance. Clinical studies have suggested that taking probiotics with prescribed medication helps to fast-track treatment.

4. Lean Meat, Fish, and Egg

 These are good proteins for ulcer patients. Lean meats are less fatty, so they are less likely to irritate the stomach lining. Also, taking boiled fish and eggs are better than fried ones.

5. Honey

Raw unprocessed honey is an effective healing and soothing agent for the body. Some people have reported that honey helps to soothe the pain that comes with indigestion and ulcer episodes.

6. Moi-Moi

 Most people with ulcer complain of having acid reflux when they eat beans. However, Moi-Moi is great for ulcer patients. It’s made from pureed beans, and it takes less time to digest, unlike beans. Remember to make it less spicy as spicy foods can irritate the stomach.

7. Wheat

Wheat is an all-purpose grain that gives nutritional and health value to everyone including ulcer patients. This is because wheat is filled with nutrients such as Vitamin E, mineral salts, Vitamin B, copper, zinc, calcium, magnesium, and so on which are not only good for the health, but can also help manage peptic ulcer.

8. Millet and Pap

Fermented foods like pap are rich sources of microbes such as fungi and yeasts. Eating such food that contains microbes can help balance the gut.

9. Plant-based oils, such as olive oil & canola oil

Using olive oil for cooking and baking also benefits people with stomach ulcers. It is moderately effective in treating H. pylori infection.

10. Natural Seasoning
