More than a billion people around the world suffer from at least occasional episodes of gastroesophageal reflux disease (GERD), more commonly known as acid reflux. Several recent studies have shown that a vegan diet that is also low in spicy foods and citrus foods can can help reduce episodes of GERD. Of course, the vegan diet has also consistently shown to help protect against heart attacks, stroke, colorectal cancers, diabetes, obesity and many other maladies and has also shown to increase lifespan and overall health.
