Fruits
Maintain a colorful diet filled with fruits rich in an antioxidant known as polyphenols. This antioxidant helps protect you from ulcers and stimulates healing. Polyphenol-rich fruits include blueberries, raspberries, strawberries, elderberries, and blackberries.
Bananas are also known as ulcer-healing fruit, and if consumed raw and ripe. It is rich in antibacterial compounds that hinder the growth and development of the H.pylori bacteria that trigger stomach ulcers. It is no surprise that banana can help improve symptoms of this disease because it is known to promote digestive tract health. It also helps to decrease the acidity of gastric juices, preventing organ inflammation and strengthens the stomach lining.
A type of banana known as plantain also provides similar health benefits. Unripe plantains contain a flavonoid called leucocyanidin. Leucocyanidin stimulates mucus production in the stomach, which helps lower acidity levels, alleviating symptoms of ulcers.
