What should I feed someone going through Colorectal Cancer treatment

Nutrition During Colorectal Cancer Treatment

Nutrition is an important part of supporting your body during colorectal cancer treatment. Here's what the evidence shows about feeding someone undergoing this care:

General Nutrition Principles

According to the NCCN Guidelines for Colon Cancer, survivors and patients undergoing treatment should focus on:

• Plant-based foods: Emphasize fruits, vegetables, whole grains, and legumes
• Lean proteins: Include poultry and fish regularly
• Limit red and processed meats: These have been associated with worse outcomes in colorectal cancer patients
• Whole grains over refined grains: Choose brown rice, whole wheat bread, and oatmeal
• Reduce concentrated sweets and sugar-sweetened beverages: Research shows higher sugar intake is linked to increased recurrence risk in stage III colon cancer patients

Important Considerations During Active Treatment

Bowel function changes are common during colorectal cancer treatment, especially if the patient has had surgery or radiation. The NCCN Guidelines recommend:

• Modify diet based on bowel symptoms: If someone experiences diarrhea, constipation, or other digestive issues, diet adjustments are necessary
• Anti-diarrheal agents and bulk-forming agents may be recommended by their care team alongside dietary changes
• Work with a dietitian: A specialist can help customize meals based on individual tolerance and side effects

Specific Dietary Adjustments

If experiencing diarrhea:

• Lower fiber initially (contrary to general recommendations)
• Bland, easily digestible foods
• Adequate hydration
• Small, frequent meals

If experiencing constipation:

• Gradual increase in fiber
• Adequate fluids
• Prune juice or other natural remedies

General supportive nutrition:

• Adequate calories to maintain weight
• Sufficient protein for healing and recovery
• Calcium and dairy products (some evidence suggests higher postdiagnosis milk and calcium intake may be associated with lower death risk)

What to Avoid

• Alcohol (drink sparingly, if at all)
• Smoking-related products
• Foods that trigger individual digestive symptoms

Key Takeaway

There is no one-size-fits-all diet for colorectal cancer patients. The best approach combines general healthy eating principles with individualized modifications based on the person's specific symptoms and treatment side effects.

Questions to Ask Their Healthcare Team:

1. Should we see a registered dietitian who specializes in oncology nutrition?
2. What specific foods should we avoid based on their current treatment and symptoms?
3. Are there nutritional supplements recommended if they're having trouble eating?
4. How should we adjust meals if they experience nausea, loss of appetite, or digestive changes?
5. What are safe ways to maintain healthy weight during treatment?
