Diet study hopes to boost survival in colorectal cancer patients
NCT ID NCT01570010
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether following the Norwegian dietary guidelines—including healthy foods, cooking classes, and physical activity—can improve survival and reduce cancer recurrence in 503 people who had colorectal cancer. Participants are guided by nutritionists and given food discounts to help them stick to the diet. The goal is to see if eating well can dampen inflammation and oxidative stress, potentially leading to better long-term outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Norwegian food based dietary guidelines (healthy diet, cooking courses, food discounts, and physical activity)
- What this could lead to
- If it works, this could show that following a healthy diet helps colorectal cancer survivors live longer and lowers the chance of cancer coming back.
- What could go wrong
- This is an early-stage study with no prior strong evidence, and diet changes can be hard to stick to. The results may not apply to all patients or cancer types.
