According to Dr. Koufman, however, alkaline water can benefit people who suffer from acid reflux because, as her
published research has found, the stomach enzyme pepsin dies at pH 8. Pepsin is responsible for inflammation in the ears, nose, and throat, but when alkaline water touches the tissues of the throat and esophagus, it helps wash out pepsin. “Alkaline water does help wash out stomach enzymes and [the] esophagus, [so] it can alleviate reflux symptoms, even undiagnosed ones,” she says.
