30 Foods That Cause Acid Reflux
Orange Juice

Citrus fruits and fruit juices such as orange juice are among the most frequent causes of acid reflux because of their high acidity. The fiber may help your digestive system a little, but it's best to avoid orange juice altogether.
However, some companies offer low-acid varieties of orange juice, which may help limit the occurrence of the condition in some people. It varies from person to person, so try a little before drinking a full glass.
