A clear liquid diet is made up of a diet only contains transparent liquid foods that do not contain any solid particles. It is sometimes called a "surgical liquid diet" because of its perioperative uses. This includes vegetable broth, bouillon (excepting any particulate dregs), clear fruit juices such as filtered apple juice, clear fruit ices or popsicles, clear gelatin desserts, and certain carbonated drinks such as ginger-ale and seltzer water. It excludes all drinks containing milk, but may accept tea or coffee. Typically, this diet contains about 500 calories per day, which is too little food energy for long-term use.
