Cancer and Nutrition
How Diet Affects Cancer Risk
Research shows that some foods can raise your cancer risk, while others can help protect your body.
- Diets high in processed foods, red meat, and added sugar may increase cancer risk.
- Diets rich in fruits, vegetables, whole grains, and lean proteins can help lower that risk.
- Foods with antioxidants—like berries, leafy greens, and nuts—may help protect your cells.
The American Cancer Society states cancer is the second leading cause of death in the U.S. About 1 in 5 cancers are linked to extra body weight, not being active, unhealthy eating, or drinking too much alcohol. Making healthy choices can greatly lower your chances of developing cancer.
Eating Well During Cancer Treatment
Cancer treatment can make eating difficult. You might feel sick, tired, or have side effects that make food less appealing. But getting enough nutrients is very important.
Why Good Nutrition Matters During Treatment
Many people with cancer become malnourished because treatment can increase metabolism while decreasing appetite. Side effects like nausea, diarrhea, mouth sores, and taste changes can also make eating harder.
Eating well during treatment can help you:
- Feel stronger
- Keep your energy up
- Maintain a healthy weight
- Handle treatment side effects better
- Lower your risk of infection
- Heal and recover faster
Planning ahead can make it easier to get the nutrients you need.
Getting Ready for Treatment
Eating well before treatment helps your body prepare. It gives you extra strength, supports your immune system, and helps your body repair tissues.
Here are some helpful tips:
- Stock up on favorite foods so you don’t have to shop as often.
- Cook meals ahead of time and freeze them in portions.
- Ask friends or family to help with shopping or cooking.
- Talk to your care team about possible eating problems and how to manage them.
Healthy Eating After Cancer Treatment
Many people wonder what comes next after treatment. Good nutrition is a powerful way to take charge of your health.
Healthy eating can help you:
- Recover and heal
- Regain strength and reach a healthy weight
- Manage any ongoing side effects
- Lower your risk of future cancer
- Stay healthy long-term
