Chemotherapy and Nutrition: A Simple Guide

Treating cancer with chemotherapy can feel overwhelming. It can also come with some unpleasant side effects. Good nutrition is one way to support your body. Many side effects can be eased with the right food choices.

Helpful ways to manage common side effects

Constipation

  • What helps: Eat more fiber slowly over time. Good sources include whole grains, fruits, vegetables, beans, and nuts.
  • Drink fluids: Aim for at least 8 cups of water or other drinks daily.
  • Check first: Always ask your care team before using supplements or laxatives.

Nausea

  • Small meals: Eat small amounts more often to avoid an empty stomach.
  • Ginger: Try ginger tea, ginger candies, or ginger soda.
  • Cool foods: Choose foods that are cold or room temperature.
  • Things to avoid: Greasy foods, strong smells, and eating during cooking.

Diarrhea

  • Gentle foods: Choose soft, low-fat, low-fiber foods like cooked chicken, eggs, white rice, and canned fruits.
  • Stay hydrated: Sip water or sports drinks with electrolytes throughout the day.
  • Salty snacks: Crackers or pretzels can help replace lost salt.

Sore or Dry Mouth

  • Soft foods: Smoothies, yogurts, mashed potatoes, and soups can be soothing.
  • Add moisture: Use sauces, broth, or milk to soften food.
  • Avoid: Citrus fruits, spicy foods, alcohol, and crunchy snacks.

Loss of Appetite or Weight Loss

  • Eat often: Try 5–6 small meals a day.
  • Snack smart: Keep easy snacks nearby like granola bars, fruit, yogurt, or nuts.
  • Drink calories: Smoothies, milk, or 100% juice are more helpful than water or tea.
  • Ask for help: Talk to a dietitian about fiber intake if you feel full quickly.

Weight Gain

  • Healthy snacks: Choose fruits, veggies, yogurt, or hummus instead of sweets.
  • Stay active: Even stretching or taking a short walk can help with energy and weight management.
  • Emotional eating: If stress affects your eating, ask about support groups or counseling.

Neutropenia (Low White Blood Cells)

  • Food safety is key: Wash hands often, cook food well, and avoid risky foods like runny eggs, raw sprouts, or unpasteurized dairy.
