Explain Clear Liquid Diet

Clear Liquid Diet:  It is composed  of  foods with  low residue content which  help  to minimize  the  load of food needing digestion  in  the  intestines. The clear liquid diet provides foods  and fluids that are clear and  liquid at room  temperature. The type of liquid provided may vary  depending upon  the clinical  condition of the patient,' the diagnostic test or procedure, or specific surgery a patient is undergoing. The purpose of  the clear liquid diet is to provide fluids and electrolytes to prevent dehydration. The diet is inadequate in calories and  in essential nutrients. The clear liquid diet  should not be the sole source of nourishment for more than 1  to 3 days without protein, calorie, vitamin and mineral supplementation. The clear liquid diet leaves minimal residue in the gastrointestinal tract.  It also minimizes stimulation of  the gastrointestinal  tract.
