7. Soda
Guardian
Much like coffee, caffeinated sodas may also cause acid reflux. Many kinds of soda are high in acid, especially the cola or fruit flavored ones. In addition, soda contains carbon dioxide to make the sodas carbonated. All the bubbles that come from carbonated drinks can also force the esophageal sphincter to open, allowing the acid to creep back up the esophagus causing heartburn. Moreover, remember that these stomach acids can even damage your teeth over time, and most are chockful of sugar as well. Although water is always a better choice, if you decide to drink soda, keep it to a minimum and try not to have it every single day.
