Nutrition Basics for Bowel Cancer — Eating Well During and After Treatment
Food choices play a major role in both reducing risk and supporting recovery from bowel cancer. While there’s no single “anti-cancer diet,” the right nutrition can help your body cope with treatment, maintain strength, and improve quality of life.
General Principles
- Aim for a balanced diet with whole grains, fruits, vegetables, lean proteins, and healthy fats.
- Limit processed and red meats, which are linked with higher bowel cancer risk.
- Reduce alcohol and sugary drinks.
- Prioritise fibre long-term, but adjust intake based on treatment stage and tolerance.
During Treatment
- After surgery: A temporary low-fibre (low-residue) diet may be advised to rest the bowel, before fibre is gradually reintroduced.
- Chemotherapy: Soft, bland foods may be easier if you experience nausea or taste changes. Staying well-hydrated is key.
- Radiotherapy: Some people need to avoid very high-fibre or gas-forming foods if bowel sensitivity increases.
Foods That Support Recovery
- High-protein foods: Eggs, fish, poultry, legumes, and dairy support healing.
- Fibre-rich foods: Whole grains, beans, vegetables, and fruit support bowel regularity once tolerated.
- Healthy fats: Olive oil, avocado, nuts, and seeds provide energy and reduce inflammation.
- Probiotics: Yoghurt and fermented foods may help restore gut bacteria, especially after antibiotics.
Practical Tips
- Eat small, frequent meals if your appetite is low.
- Keep a food and symptom diary to identify foods that trigger discomfort.
- Work with a dietitian for personalised guidance, especially if you have a stoma or ongoing digestive issues.
Takeaway
Nutrition is not just about reducing cancer risk — it’s about supporting your body during treatment and recovery. Eating well helps maintain energy, strengthen the immune system, and improve overall wellbeing.
