clear-liquid diet [L, clarus + liquere, to flow] , a diet that supplies fluids and provides minimal fiber, primarily to relieve thirst and maintain water balance. Liquid is at room temperature and consists primarily of dissolved sugar and flavored liquids, such as ginger ale, sweetened tea or coffee, fat-free broth, plain gelatin desserts, and strained fruit juices. The diet is often used postoperatively until bowel function returns. It is nutritionally inadequate and should not be used for more than two days.
