Full liquid diet

Description

A full liquid diet is made up only of fluids and foods that are normally liquid and foods that turn to liquid when they are at room temperature, like ice cream. It also includes:

You cannot eat solid foods when you are on a full liquid diet.

Why You May Need This Diet

You may need to be on a full liquid diet right before a medical test or procedure, or before certain kinds of surgery. It is important to follow the diet exactly to avoid problems with your procedure or surgery or your test results.

You also may need to be on a full liquid diet for a little while after you have had surgery on your stomach or intestine. You may also need to be on this diet if you are having trouble swallowing or chewing. If you are prescribed this diet for dysphagia (swallowing problems), your speech pathologist will give you more specific guidelines. Sometimes the full liquid diet is a step to advance from a clear liquid diet to your regular diet.

What You Can Eat and Drink

You can eat or drink only things that are liquid. You may have these foods and drinks:

Ask your health care provider or dietitian if you can include these foods in your full liquid diet:

Do not eat any kind of cheese, fruit (fresh, frozen, or canned), meat, and cereals that are not on your "OK" list.

Also, do not eat raw or cooked vegetables. And do not eat ice cream or other frozen desserts that have any solids in them or on top, such as nuts, chocolate chips, and cookie pieces.

Try having a mix of 5 to 7 of the foods you can eat for breakfast, lunch, and dinner.

Liquid foods do not include mashed foods, such as mashed potato or avocado.

Eating only a full liquid diet can give you enough energy, protein, and fat. But it does not give you enough fiber. Also, you may not get all the vitamins and minerals you need. So, your provider may recommend that you take certain vitamins and supplements.

This diet is safe for people with diabetes, but only when they are followed closely by their provider.

Adding More Calories

For most people on a full liquid diet, the goal is to get 1,350 to 1,500 calories and 45 grams of protein a day.

If you need to be on a full liquid diet for a long time, you will need to be under the care of a dietitian. Ask your provider if you can eat these foods together to add calories:
