Many people dont know that SIBO can cause acid reflux. Fermentable carbohydrates, high fiber foods, and high fodmap foods are problematic when SIBO is the cause of heartburn. Resistant starches found in bananas and potatoes or high FODMAP foods such as onion, garlic, and asparagus. Corn, legumes, wheat, and high fiber are also often problematic. These are foods to avoid if someone has SIBO and acid reflux or if you notice any of these highly fermentable foods as your trigger. ~ Didem
