Eating well when you have cancer

Cancer and treatments for cancer can affect your appetite and enjoyment of food, making it difficult for you to eat well. But losing weight or having a reduced food intake can make it harder to cope with treatments like surgery, radiotherapy and chemotherapy.

During these times you may need to change the balance of your diet to include different foods. It may also be helpful to alter when or how often you eat to make sure you eat enough. These may be short- or long-term changes depending on your treatment and health.

What foods should I try to eat?

We should all try to eat a wide variety of different foods to make sure we get the nutrition our bodies need.

Foods Function
Meat, fish, eggs, tofu, soya products, pulses (beans and lentils), Quorn, nuts These are a good source of protein, which is needed for the growth of body tissue, muscle strength and wound healing. Some also contain fat, so are a good source of energy (calories). They also contain vitamins and minerals.
Dairy products (such as cheese, milk, yoghurt and fromage frais) and non-dairy alternatives (such as soya milk and soya yoghurt) These contain protein, fat, vitamins and minerals. If you are losing weight choose the full-fat varieties. If eating non-dairy alternatives choose those that are fortified with vitamins and minerals.
Bread, chapatis, pitta bread, naan and roti
Potatoes, sweet potatoes and yam
Rice, pasta and noodles
Buckwheat, couscous and bulgar wheat
Biscuits and crackers
These starchy foods contain energy. Some may also contain fibre, vitamins and minerals.
Sugar, honey, syrup, treacle and sugary foods, such as chocolate, cakes and sweets These are good sources of energy.
Butter, margarine, oil, ghee and cream These are good sources of energy and contain fat-soluble vitamins.
Fruit and vegetables Good sources of vitamins and minerals, but not usually of protein and energy. If you have a poor appetite you may need to reduce your normal quantities to enable you to eat higher energy foods.
Drinks Aim to drink eight to ten cups or glasses each day. If you have a poor appetite choose nourishing drinks rather than just tea, coffee or water.

Are there any foods I should avoid?

When you are ill or having treatment you are more at risk of getting food poisoning. It is best to avoid the following foods:

  • raw or lightly cooked eggs
  • soft, ripened cheese such as Brie, Camembert, or blue-veined cheese such as Stilton
  • pâté.

Already following a different diet?

If you are already following a diet for other health reasons you may wish to discuss this with a dietitian.
