If you have trouble chewing and swallowing, you may need to add sauces and gravies. Sometimes, you may need to eat low-fiber foods instead of those with high fiber. Your dietitian can help you with any diet changes you may need to make.

- Think of your cancer treatment as a time to get well and focus just on yourself.
- Eat a healthy diet before treatment starts. This helps you stay strong during treatment and lowers your risk of infection.
- Go to the dentist. It is important to have a healthy mouth before you start cancer treatment.
- Ask your doctor, nurse, or dietitian about medicine that can help with eating problems.
- Discuss your fears and worries with your doctor, nurse, or social worker. He or she can discuss ways to manage and cope with these feelings.

- Fill the refrigerator, cupboard, and freezer with healthy foods. Make sure to include items you can eat even when you feel sick.
- Stock up on foods that need little or no cooking, such as frozen dinners and ready-to-eat cooked foods.

Make a list of questions for your meeting with the dietitian. Ask about your favorite foods and recipes and if you can eat them during cancer treatment. You might want to find out how other patients manage their eating problems. You can also bring this book and ask the dietitian to mark sections that are right for you.
If you are already on a special diet for diabetes, kidney or heart disease, or other health problem, it is even more important to speak with a doctor and dietitian. Your doctor and dietitian can advise you about how to follow your special diet while coping with eating problems caused by cancer treatment.
For more information on how to find a dietitian, contact the American Dietetic Association. See “Ways to Learn More” for ways to reach them.

- Eat plenty of protein and calories when you can. This helps you keep up your strength and helps rebuild tissues harmed by cancer treatment.
- Eat when you have the biggest appetite. For many people, this is in the morning. You might want to eat a bigger meal early in the day and drink liquid meal replacements later on.
- Eat those foods that you can, even if it is only one or two items. Stick with these foods until you are able to eat more. You might also drink liquid meal replacements for extra calories and protein.
- Do not worry if you cannot eat at all some days. Spend this time finding other ways to feel better, and start eating when you can. Tell your doctor if you cannot eat for more than 2 days.
- Drink plenty of liquids. It is even more important to get plenty to drink on days when you cannot eat. Drinking a lot helps your body get the liquid it needs. Most adults should drink 8 to 12 cups of liquid a day. You may find this easier to do if you keep a water bottle nearby. See the list of clear liquids for other ideas.

- Do not be surprised or upset if your loved one’s tastes change from day to day. There may be days when he or she does not want a favorite food or says it tastes bad now.
- Keep food within easy reach. This way, your loved one can have a snack when he or she is ready to eat. You might put a snack-pack of applesauce or pudding (along with a spoon) on the bedside table. Or try keeping a bag of cut-up carrots on the refrigerator shelf.
- Offer gentle support. This is much more helpful than pushing your loved one to eat. Suggest that he or she drinks plenty of clear and full liquids when he or she has no appetite. For ideas, see the lists of clear liquids and full-liquid foods.
- Talk with your loved one about ways to manage eating problems. Doing this together can help you both feel more in control.
