Nutrition and Cancer: Clear Liquids and Full Liquids
You may have some side effects during your cancer treatment, such as nausea or diarrhea. To help you deal with the side effects, you may need to limit your diet for shore amounts of time. You will still need to drink fluids for nourishment, to quench your thirst, or to settle your stomach. There are two general types of liquids: clear and full. Don't limit yourself to liquids unless your doctors tell you to do so.
Clear liquids may be very helpful if you have these side effects:
Loss of appetite
In general, clear liquids are liquids that are easy to see through and pour. A clear liquid diet does not provide enough nutrition. For this reason, it should only be followed for a short time to help control your symptoms from side effects of treatment. If you are having symptoms that will not allow you to eat or drink anything more than clear liquids, talk with your healthcare provider.
Clear liquids include:
Clear, fat-free broth
Clear carbonated beverages
Apple, cranberry, or grape juice
Fruit ices without fruit pieces or milk
Clear nutritional drinks
Full liquids have more calories, protein, and nutrients than clear liquids. They can help meet your daily calorie and protein requirements. They are especially useful if you have a loss of appetite, vomiting, or weight loss. Full liquids include those that are easy to pour and/or can be sucked through a straw. Some liquids are considered both clear and full.
Full liquids include:
Soup that has been strained or put through a blender
Custard (soft or baked)
Fruit purees that are watered down
Ice cream with no chunks (such as nuts or cookie pieces)
Yogurt (plain or vanilla)
Instant breakfast drinks
Liquid meal replacements
Clear nutrition drinks
Ask your healthcare provider if refined cooked cereals such as oatmeal and grits are allowed.
