Ultra-processed foods (UPFs) are linked to the development and worsening of colorectal cancer. Studies show these foods not only increase the risk of developing the disease but also accelerate its progression after diagnosis.
One study, funded by the US National Institutes of Health and the American Cancer Society, found that higher UPF consumption after diagnosis increased the risk of cardiovascular-related deaths among colorectal cancer survivors, while another study from the University of South Florida showed how these foods contribute to inflammation and worsen cancer outcomes [1, 2].
How Ultra-Processed Foods Contribute to Cancer Growth
Recent research funded by the US National Institutes of Health and the American Cancer Society reveals that ultra-processed foods (UPFs) contribute to chronic inflammation, a major factor in tumor growth. A diet high in UPFs, including inflammatory oils, creates an environment that accelerates colorectal cancer development and progression. This reinforces the growing evidence that diet directly impacts cancer risk. One study found that for colorectal cancer survivors, higher UPF consumption weakened the body’s natural healing processes, making recovery more difficult. While no direct link to cancer recurrence was found, the study emphasized how these foods can complicate recovery [1].
Ultra-Processed Foods and Colorectal Cancer Survivors
Diet plays a key role in both preventing cancer and supporting long-term health after a colorectal cancer diagnosis. Research shows that survivors who continue to consume ultra-processed foods (UPFs), such as processed meats, sugary snacks, and fatty condiments, face higher risks of serious health complications beyond cancer itself.
A large study of over 2,400 colorectal cancer survivors found that those who ate more UPFs had an increased risk of dying from heart disease, one of the leading causes of death among survivors [1]. The study highlights that these foods don’t just impact cancer risk—they can also worsen overall health by increasing inflammation, impairing metabolic function, and making it harder for the body to heal after treatment.
For survivors, long-term dietary choices matter. A diet high in UPFs may not directly cause cancer recurrence, but it can slow recovery, weaken immune function, and make it more difficult to manage the lasting effects of chemotherapy, surgery, and radiation [1]. In contrast, prioritizing whole, nutrient-rich foods—such as fresh vegetables, lean proteins, and healthy fats—can support healing and improve overall survival rates.
Resolution Medicine: A Natural Approach to Healing
Ultra-processed foods contribute to chronic inflammation, making colorectal cancer more difficult to manage. In response, a growing field called resolution medicine is exploring how natural foods can help reduce inflammation and support healing alongside conventional treatments.
Scientists are studying how healthy fats—such as those in avocados, fish, and olive oil—may counteract the inflammatory effects of ultra-processed foods [2]. Research from the University of South Florida found that chemicals in processed foods can interfere with the body’s ability to regulate inflammation, potentially slowing recovery and affecting long-term health [2].
Early studies suggest that fish oil supplements may help the body manage inflammation more effectively, offering a potential tool for improving cancer outcomes [2]. While more research is needed, resolution medicine reinforces the growing evidence that diet plays a direct role in both cancer prevention and recovery.
What You Can Do Now
What you eat plays a crucial role in both preventing colorectal cancer and supporting recovery. Cutting back on ultra-processed foods and focusing on whole, nutrient-dense options—such as fresh vegetables, fish, lean meats, and whole grains—can help reduce inflammation, a key driver of cancer progression. For colorectal cancer survivors, diet is not just about recovery; it’s also about lowering the risk of complications like cardiovascular disease, which remains a leading cause of death among survivors.
Making these food choices—along with exploring natural treatments like resolution medicine—could make a real difference in improving health outcomes. The right foods are transformative in both preventing colorectal cancer and enhancing life after treatment.
PS: As we observe National Colorectal Cancer Awareness Month, consider taking proactive steps with tools like Colonox FIT, an at-home test that helps you monitor your colorectal health and take control of your well-being.
Key Takeaways
- Ultra-processed foods (UPFs) fuel cancer growth – These foods cause inflammation, making it easier for tumors to grow and harder for the body to heal.
- Cancer survivors should watch their diet – Eating more UPFs increases the risk of heart disease and slows recovery after colorectal cancer treatment.
- Healthy fats can help fight inflammation – Foods like fish, avocados, and olive oil may help reduce inflammation and support healing.
- Whole foods are the better choice – Eating fresh vegetables, lean meats, and whole grains instead of processed foods can lower cancer risk and improve recovery.
- At-home screening makes a difference – Tools like Colonox FIT help monitor colorectal health, making early detection and prevention easier.
