Good nutrition is an important part of cancer care. Eating a healthy, balanced diet can help your body stay strong during treatment and support your recovery. It can also make it easier to handle side effects, lower your risk of problems, and improve your overall well-being.
Cancer and its treatments can affect how your body uses food. They can also cause side effects that make it hard to eat or get enough nutrients. Some common side effects include nausea, vomiting, diarrhea, constipation, changes in taste, dry mouth, trouble swallowing, loss of appetite, and weight or muscle loss.
Because every person’s experience with cancer is different, it’s important to have a nutrition plan that meets your individual needs. A team of healthcare providers, including registered dietitians, can help you manage side effects and stay strong.
Here are some helpful tips for eating well during cancer treatment:
- Try to eat a variety of fruits, vegetables, whole grains, lean proteins (like chicken, fish, beans), and healthy fats (like nuts and olive oil).
- Eat small meals throughout the day if your appetite is low or if large meals upset your stomach.
- Change the texture or temperature of foods if you have trouble chewing, swallowing, or if your mouth is sore.
- Drink plenty of fluids, especially if you’re not eating much. Nutrient-rich drinks like smoothies or soups can be helpful.
- Limit highly processed foods, sugary snacks, and foods high in saturated fat.
- Talk to a registered dietitian if you’re losing weight, feeling very tired, or having trouble eating.
There isn’t one “ideal” diet for everyone with cancer. What works best depends on your treatment, symptoms, and personal needs. Nutrition needs can also change over time, so it’s a good idea to check in with your healthcare team regularly.
