Nutrition, Colorectal Cancer, and CF

March is a powerful month for raising awareness, bringing attention to both Nutrition Month and Colorectal Cancer Awareness Month. For those living with cystic fibrosis (CF), both topics are critical, as nutrition plays a direct role in maintaining overall health, and CF-related digestive complications can increase the need for proactive colorectal cancer screening.

The Link Between CF, Nutrition, and Digestive Health

Cystic fibrosis doesn’t just affect the lungs — it has a profound impact on digestion and nutrient absorption. Many with CF struggle with pancreatic insufficiency, meaning the body has difficulty breaking down and absorbing essential nutrients, including fat-soluble vitamins (A, D, E, and K). Proper nutrition isn’t just about fueling the body — it’s about staying strong, reducing inflammation, and supporting long-term gut health.

Why Colorectal Cancer Awareness Matters for People with CF

Studies have shown that individuals with cystic fibrosis have an increased risk of colorectal cancer (CRC), especially those who have undergone a lung transplant. The CF Foundation recommends regular colorectal cancer screening starting at age 40- earlier than the general population- due to this heightened risk.

Being proactive about gut health and screenings can significantly impact early detection and prevention. While colorectal cancer is often thought of as an older adult’s disease, people with CF should take action earlier.

Fueling Your Body: Nutrition Tips for the CF Community

A strong diet can serve as a powerful tool for both optimizing health and reducing cancer risk. Here are some CF-friendly nutritional strategies:

Prioritize High-Calorie, Nutrient-Dense Foods

CF increases calorie demands, so healthy fats (avocados, olive oil, nuts, and seeds) are essential.
Lean proteins (chicken, fish, eggs, and plant-based options like tofu) help maintain muscle mass.

Focus on Fiber for Gut Health

A diet rich in fiber (whole grains, beans, fruits, and vegetables) supports digestion and can help reduce CRC risk.
If fiber intake is a challenge, gradually increase fiber while staying hydrated to prevent digestive discomfort.

Optimize Vitamin Intake

Because CF can make it harder to absorb vitamins A, D, E, and K , supplements or fortified foods are crucial.
Regular vitamin level checks with your CF care team can ensure you’re meeting your needs.

Stay Hydrated

CF can cause increased salt loss, making hydration even more important.
Electrolyte-rich fluids (like sports drinks, broths, or coconut water) can help maintain balance.

Staying Proactive: Preventative Steps for CRC in CF

Being proactive means not just fueling your body but also taking control of your health through preventative care. Here’s what you can do:

Start Screening Early: If you’re 40 or older, talk to your doctor about colorectal cancer screening options like colonoscopies.
Know the Symptoms: Persistent changes in bowel habits, unexplained weight loss, or abdominal discomfort should be addressed with your healthcare provider.
Maintain a Balanced Diet: A gut-friendly diet can support digestive health and reduce CRC risk.
Stay Active: Regular physical activity supports overall health, digestion, and immune function.

Empowering the CF Community

Raising awareness about nutrition and colorectal cancer risk in cystic fibrosis is key to helping people with CF live longer, healthier lives. By prioritizing proper nutrition, gut health, and early screenings, we can take proactive steps toward better health outcomes.

At the Filotimo Foundation, we’re committed to empowering the CF community with education, resources, and advocacy. This March, let’s start the conversation, act, and fuel our bodies for a stronger future.
