Coffee is another type of food that can cause heartburn. Because coffee is high in acid, it’s another food that can trigger acid reflux, especially when consumed in large amounts. As the caffeine in coffee increases the risk of heartburn, it also causes the esophageal sphincter to relax, allowing the acid back up through the esophagus. Most experts will suggest that people with GERD or acid reflux choose not to drink coffee at all, but if you find this a difficult rule to follow, be sure to drink your coffee in the morning and not all throughout the day. Remember, even decaf coffee can still be high in acid, so be sure to drink any type of coffee in moderation.
