clear liquid diet

(kleer LIH-kwid DY-et)

A diet that is made up of only liquids and foods that are clear liquids at room temperature. Clear liquids are easy to digest and include water, broth, gelatin, plain tea and coffee, popsicles and juices without pulp, sodas, and sports drinks. Clear liquid diets may be used before certain tests or procedures, such as a colonoscopy, or before or after certain types of surgery. They may also be used to help treat gastrointestinal problems, such as nausea, vomiting, or diarrhea. Clear liquid diets are normally used for only a few days because they do not have enough of the calories and nutrients the body needs.
