Really? A 2018 study showed significantly decreased GERD symptoms with fiber supplementation, but no other dietary changes, in 30 people with low baseline fiber intake. Mechanisms may include increased gastric motility (less available to reflux), increased gastroesophageal sphincter pressure, and favorable changes to the gut microbiome. Over 90% of Americans do not consume adequate fiber. The supplement in the study totaled 12.5 g soluble fiber daily, which is like eating oatmeal with fruit, a big salad, and a cup of beans. Could fiber help patients on chronic proton pump inhibitors with no true indication wean off of them, thereby decreasing their risk of GI infections, malabsorption, and osteoporosis?
