Onions
Onions, particularly raw versions, are a relatively common cause of acid reflux. Like other foods mentioned in this article, onions would relax your lower esophageal sphincter and trigger the symptoms. What is more, this ingredient is high in fermentable fiber, a substance that would lead to belching. When consumed too excessively, belching could worsen acid reflux and disrupt your daily life. In fact, the fermentable fiber in onions belongs to FODMAPS, a group of elements that might cause digestive problems. Thus, try to limit your consumption of onions in salads, hamburgers, and raw onions as well to reduce the risk. [9]
