• Clear Liquid Diet

    A clear liquid diet is a diet consisting of foods and beverages made from liquids that you can see through. This type of diet is easily digested and leaves no residue in the gastrointestinal tract.
    In the past, a clear liquid diet was routinely prescribed for hospitalized patients, often for several days. These days, though, it is generally avoided, unless absolutely necessary. A clear liquid diet may be necessary when the gastrointestinal tract needs to be free of food or needs to rest, for instance:
    Although this diet allows for adequate hydration, it does not provide enough calories and nutrients. Therefore, be sure your doctor is following you closely while you are on this diet. Also, do not stay on this diet for more than a few days.
