Eating well during cancer treatment means getting enough calories and protein to help prevent weight loss and regain strength. Eating well often helps people feel better and have more energy.

Some people with cancer find it hard to eat well. They may lose their appetite. In addition to loss of appetite, common side effects of treatment, such as nausea, vomiting, or mouth sores, can make eating difficult. Often, foods taste different. Also, people being treated for cancer may not feel like eating when they are uncomfortable or tired.

Doctors, nurses, and dietitians can offer advice for healthy eating during cancer treatment. Patients and their families also may want to read the National Cancer Institute booklet Eating Hints for Cancer Patients, which contains many useful suggestions.
