Clear Liquid Diet

A clear liquid diet is often recommended to prepare for certain medical tests or procedures, especially surgical procedures, that require no food in your stomach or intestines. It may also be recommended for post-surgical periods and for patients experiencing nausea, vomiting or diarrhea. Clear liquid means you may consume only food and drinks that you can see through, even though they may have color, such as apple juice. A clear liquid diet does not contain an adequate supply of calories and nutrients and should not be used for more than a few days.
