Some antacid foods include milk, licorice, ginger, banana, cumin seeds, vinegar, yogurt, papaya and aloe vera. Baking soda is a common cooking ingredient that can reduce acid in the stomach.
Most of these antacid foods are less expensive than over-the-counter and prescription medicines that are designed to have the same type of effect on the stomach.
Antacids neutralize acidity in the stomach, hence increasing its pH level. They also minimize or block the secretion of acid by gastric cells. In addition, antacids change the profile of prostaglandins, which are produced by gastroduodenal mucosa. This process usually promotes healing in the body.
