Does Dr. Pepper Contain Prune Juice?
For some unknown reason, a theory has persisted that one of the ingredients in Dr. Pepper is prune juice. The belief has persisted since 1930 and believed to have originated through a rumor started by a competitor’s deliveryman in an attempt to stop store owners from stocking their shelves with the soda. Prune juice is often associated with side effects like constipation and bloating which would be detrimental to a soda brand’s rising popularity. Despite the somewhat convincing nature of the theory, the owners of Dr. Pepper have dispelled the rumor by clearly stating their beverage doesn’t contain prune juice.
