* Examples of clear liquids include water, fruit juices without pulp, carbonated beverages such as 7-Up or Sprite, clear tea, and black coffee (no cream or sugar). Because non-human milk is similar to solids in the digestive process, the amount ingested must be considered when determining an appropriate fasting period.
