Cancer Nutrition: What to eat when you have cancer?


Facing cancer is a journey filled with many questions, especially about what to eat. Nutrition plays a vital role in supporting your body through this challenging time. You might wonder, "What foods will help me feel stronger? How can I manage side effects with my diet?" I’m here to walk you through practical advice on cancer nutrition. Together, we’ll explore how to nourish your body with kindness and care.



Understanding cancer treatment Nutrition: Fuelling your body right


When you’re undergoing cancer treatment, your body needs extra support. Treatments like chemotherapy, radiotherapy, immunotherapy or surgery can affect your appetite, digestion, and energy levels. That’s why focusing on nutrition is not just about eating, it’s about nourishment.



Why is nutrition so important?

Good nutrition helps maintain your strength, minimise weight/muscle mass loss, supports your immune system and can even improve how well you tolerate treatment. It’s about choosing foods that provide energy, protein, vitamins and minerals to help your body repair and rebuild.


Here are some key points to keep in mind:


  • Protein is your friend. It helps repair tissues and keeps your muscles strong. Think lean meats, fish, eggs, dairy, beans, and nuts.

  • Energy matters. You might need more calories than usual, especially if you’re losing weight. Healthy fats like avocado, olive oil, and nuts can boost your calorie intake.

  • Hydration is crucial. Drinking enough fluids helps with digestion and reduces fatigue. Water, herbal teas, and broths are excellent choices.

  • Vitamins and minerals. Colourful fruits and vegetables provide antioxidants and nutrients that support your immune system.


Remember, every body is different. What works for one person might not work for another. Listen to your body and adjust as needed.

Practical tips for eating well during treatment


Eating well during treatment can feel overwhelming, especially if you’re dealing with nausea, mouth sores, or changes in taste. But don’t worry! There are gentle ways to make meals more manageable and enjoyable.


1. Small, frequent meals

Instead of three big meals, try eating smaller portions more often. This can help if your appetite is low or if you feel full quickly.


2. Soft and easy-to-swallow foods

If you have mouth sores or difficulty swallowing, choose soft foods like mashed potatoes, yoghurt, smoothies, or soups.


3. Manage nausea with bland foods

When nausea strikes, bland foods like crackers, toast, or rice can be soothing. Avoid spicy or greasy foods until you feel better.


4. Boost calories and protein

Add extras like cheese, nut butters, or powdered milk to your meals to increase calories and protein without increasing volume.


5. Stay hydrated

Sip fluids throughout the day. If plain water is unappealing, try adding a slice of lemon or drinking herbal teas.


6. Experiment with flavours

Sometimes, cancer treatment changes your sense of taste. Try different herbs, spices, or marinades to find what appeals to you.


7. Keep snacks handy

Healthy snacks like nuts, seeds, fruit, or yoghurt can keep your energy up between meals.


8. Ask for Help

Don’t hesitate to reach out to a dietitian or healthcare provider for personalised advice.
