At the National Foundation for Cancer Research (NFCR), we know that food is more than fuel; it’s medicine. Proper nutrition during and after cancer treatment plays a vital role in healing, strengthening the body, and improving quality of life. While nutrition cannot cure cancer alone, a balanced, healthy diet can help your body cope with treatment, rebuild strength, and promote recovery. Why Nutrition Matters During Cancer Treatment Cancer treatments like chemotherapy, radiation, and surgery can affect your body’s needs in many ways: Increase the need for calories, protein, and nutrients Cause side effects like nausea, appetite loss, mouth sores, diarrhea, or taste changes Weaken the immune system, making it even more important to support the body with nourishing foods Good nutrition can help you: Maintain strength and energy Support healing and tissue repair Enhance immune function Manage side effects more effectively Improve treatment tolerance and overall well-being Key Principles of a Cancer-Fighting Diet Prioritize Plant-Based Foods Fill your plate with vegetables, fruits, whole grains, beans, and nuts. These foods are rich in fiber, vitamins, minerals, and antioxidants that support health. Include High-Quality Protein Protein is essential for maintaining muscle mass and repairing tissues. Good sources include lean meats, poultry, fish, eggs, dairy products, beans, tofu, and protein-rich shakes. Stay Hydrated Drink plenty of water throughout the day. Herbal teas, broths, and electrolyte solutions can help, especially if you are experiencing vomiting or diarrhea. Limit Processed and Sugary Foods Minimize consumption of heavily processed foods, sugary snacks, and red or processed meats. Focus on Healthy Fats Choose heart-healthy fats like olive oil, avocados, nuts, and fatty fish rich in omega-3 fatty acids. Coping with Common Eating Challenges Treatment can make eating difficult. Here are some tips: Remember: Flexibility is key; some days will be easier than others. Important Reminder About Supplements Some vitamins, herbs, or supplements can interfere with cancer treatments. Always talk to your oncologist or nutritionist before taking any supplements. Food-first nutrition is generally safest and most effective during treatment.
