Liquid diets are recommended for individuals with specific medical problems, such as swallowing difficulties, injury and gastrointestinal distress, for those undergoing diagnostic testing and in pre- and post-operatory situations. There are two types of liquid diets: clear liquid and full liquid. A clear liquid diet is more restrictive, only including foods that are easy to digest. A full liquid diet is more liberal with thicker and harder-to-digest foods. Liquid diets are not used for weight loss purposes and are not meant for long-term use due to the lack of all the essential nutrients.
Water
Water is involved in every function within the body and is needed by cells, tissues and organs. It provides electrolytes, maintains energy and prevents dehydration. Water is an important component of both a clear liquid and a full liquid diet. You should drink six to eight 8 ounce glasses of water each day to help flush out toxins and replenish losses.
Broth
On a clear liquid diet, you may sip broth, bouillon or consomme. Choose low sodium products when possible. While sodium is an important mineral, too much sodium in your diet will make you increasingly thirsty and can ultimately dehydrate you. If you have trouble consuming plain broth, ask your physician or dietitian if you can add herbs or spices for extra flavor.
Gelatin and Popsicles
Plain gelatin prepared with water is also allowed on a clear liquid diet. Gelatin has a thicker consistency than other liquids and will, therefore, add variety to a clear or full liquid diet. For added protein, purchase high protein gelatin products. These will help you meet your daily protein requirements and increase satiety. Popsicles that do not have fruit bits or pulp in them are also a good option. These make a great snack as they are cool and refreshing.
Beverages
You can choose from either cold or hot beverages. On a clear liquid diet, you can drink fruit juices without pulp, such as grape, apple or cranberry and clear sodas like lemon lime or ginger ale. You can also sip hot beverages such as coffee or tea. While you can have sugar or honey, you cannot add milk or cream. Once you are advanced to a full liquid diet, you may have juices with pulp such as orange or vegetable juice and thicker nectar. You may also add milk or cream to your hot beverages.
Dairy
On a full liquid diet, you may consume dairy products such as milk, cream, custard, cream soups, yogurt, ice cream, frozen yogurt, sherbet and milk-based nutritional supplements. Consuming dairy will provide your body with calcium, protein, fat, calories and other important minerals as well as increase variety in acceptable foods.
Grains
On a full liquid diet, you may begin eating some grains and starchy foods. You may eat cooked baby cereal, cream of wheat, rice, pureed oatmeal or pureed potato that has been strained and added to soup. It may take time for your body to tolerate more solid foods, so you should only consume these foods in one-half cup portions, trying only one new food at a time. Eating increasingly solid foods, such as cereals, rice and grains, will help you feel fuller and provide your body with essential vitamins and minerals.
