Key takeaways

  • Good nutrition before, during and after cancer treatment helps patients feel better, stay stronger and recover faster
  • Protein repairs body tissue and supports immunity — include lean meats, fish, poultry, eggs, dairy, nuts and lentils
  • Aim for 8-10 glasses of fluid a day unless advised otherwise, because dehydration worsens fatigue and nausea
  • For nausea, eat small frequent meals, choose bland foods like toast or rice, and avoid greasy, spicy or strong-smelling foods
  • Cancer treatment can weaken the immune system, so safe food handling is essential to avoid foodborne illness

Good nutrition is a critical part of cancer treatment. Eating the right kinds of foods before, during, and after treatment can help you feel better, stay stronger, and recover faster.

Why Nutrition Matters

Cancer and its treatments can change how your body uses food. They can also affect how your body tolerates certain foods and uses nutrients. The goals of nutrition therapy are to:

  • Prevent or reverse nutrient deficiencies
  • Minimize side effects like nausea and fatigue
  • Maximize quality of life
  • Protect immune function

Tips for Maintaining Nutrition

1. Eat High-Protein Foods

Protein helps repair body tissue and keeps your immune system healthy. Include lean meats, fish, poultry, eggs, dairy products, nuts, dried beans, peas, and lentils in your diet.

2. Stay Hydrated

Dehydration can worsen side effects like fatigue and nausea. Aim to drink 8-10 glasses of fluid a day, unless advised otherwise. Water, clear soups, and herbal teas are good choices.

3. Managing Nausea

If you feel nauseous:

  • Eat small, frequent meals instead of three large ones.
  • Choose bland foods like toast, crackers, or rice.
  • Avoid strong-smelling, greasy, or spicy foods.
  • Sip cool, clear liquids.

4. Tackling Loss of Appetite

Eat when you feel hungry, even if it's not mealtime. Keep high-calorie, high-protein snacks handy. Consider nutritional supplement drinks if solid food is difficult.

5. Food Safety is Key

Cancer treatment can weaken your immune system, making you more susceptible to foodborne illnesses. Wash all fruits and vegetables thoroughly, cook meat and eggs completely, and avoid unpasteurized dairy.

Conclusion

Every patient's needs are unique. It's important to work with a dietitian or your oncology team to develop a personalized nutrition plan that supports your specific treatment journey.
