Nutrition During Cancer Treatment

Great question! Nutrition is an important part of supporting your body during cancer treatment. Here's what the evidence recommends:

General Nutritional Goals

According to the American Cancer Society and NCCN Guidelines, the main goals during cancer treatment are to:

  • Maintain adequate calories and protein to preserve muscle mass and support healing
  • Stay hydrated — drink plenty of fluids throughout the day
  • Manage side effects like nausea, loss of appetite, or difficulty swallowing
  • Support your immune system with nutrient-dense foods

Key Nutritional Recommendations

Protein (especially important):

  • Aim for protein at each meal and snack
  • Sources: lean meats, fish, eggs, beans, nuts, yogurt, cheese
  • Helps maintain muscle and support immune function

Fruits & Vegetables:

  • Aim for variety and color (different colors = different nutrients)
  • Fresh, frozen, or canned are all fine
  • May need to be soft or blended if you have swallowing difficulties

Whole Grains:

  • Brown rice, whole wheat bread, oatmeal
  • Provide sustained energy and fiber

Healthy Fats:

  • Olive oil, avocados, nuts, fatty fish
  • Support nutrient absorption

Limit:

  • Processed foods high in sugar and salt
  • Alcohol (discuss with your doctor)
  • Foods that trigger nausea for you personally

Important Considerations

Your needs are individual — they depend on:

  • Your cancer type and stage
  • Your specific treatment plan
  • Any side effects you're experiencing
  • Your overall health

Work with a specialist: Ask your oncology team to refer you to an oncology dietitian or registered dietitian (RD). They can create a personalized nutrition plan based on YOUR specific situation, medications, and side effects.

Questions to Ask Your Care Team

  1. Should I see a dietitian who specializes in oncology?
  2. Are there specific foods I should avoid with my treatment?
  3. What should I do if I'm experiencing nausea or loss of appetite?
  4. Do I need any nutritional supplements?
  5. Are there any dietary restrictions based on my specific medications?
