Liquid Diet

Purpose A clear liquid diet is often used before tests, procedures or surgeries that require no food in your stomach or intestines, such as before colonoscopy. It may also be recommended as a short-term diet if you have certain digestive problems, such as nausea, vomiting or diarrhea, or after certain types of surgery. Diet details A clear liquid diet helps maintain adequate hydration, provides some important electrolytes, such as sodium and potassium, and gives some energy at a time when a full diet isn't possible or recommended. The following foods are generally allowed in a clear liquid diet: Water (plain, carbonated or flavored) Fruit juices without pulp, such as apple or white grape juice Fruit-flavored beverages, such as fruit punch or lemonade Carbonated drinks, including dark sodas (cola and root beer) Gelatin Tea or coffee without milk or cream Strained tomato or vegetable juice Sports drinks Clear, fat-free broth (bouillon or consomme) Honey or sugar Hard candy, such as lemon drops or peppermint rounds Ice pops without milk, bits of fruit, seeds or nuts Depending on your medical condition, your physician or dietitian may alter the above list. For certain tests, such as colon exams, your doctor may ask you to avoid liquids or gelatin with red coloring. Any foods not on the above list should be avoided. A typical menu on the clear liquid diet may look like this.
