My bf kept on getting acid reflux, sometimes cause him to have heartburn. is there any food/drink other than medicine he can take to heal over time?

Reflux treatment: Patients with reflux disease (r) need to treat it. Losing weight and avoiding certain foods can improve some symptoms. Patients with untreated r have a higher incidence of barrett's esophagitis and have an increased risk of cancer of the esophagus. Tell you bf to see a gastroenterologist and get effective treatment for it. It is better to prevent a problem than to treat it later.

Try vinegar: The most important thing to so is try to eliminate the problem (often a food intolerance). Try eliminating all wheat and gluten. Also look at other common food allergies. Sometimes slow emptying of the stomach is the problem so taking a tablespoon of apple cider vinegar (not distilled) in a small glass of water can stimulate the stomach to function better.
