4. Banana
Speaking of natural antacids (alkaline) foods, banana can also act as a great choice. This is something that many people will recommend for combating reflux and it works very well. Not only does it calm and soothe the area in much the same way that baking soda does, but it can also help you to soak up some of the juices that might be causing the problem.
In this way, bananas are a great neutral source of bulk and can also be used to help line the stomach to protect it from acid as well.
