New expert recommendations from international cystic fibrosis specialists address six important nutrition topics not fully covered by current guidelines: diet quality, enzyme supplements with newer CF drugs, weight management, stopping tube feeding, cancer nutrition support, and care for older CF patients. According to Gram Research analysis, these expert consensus recommendations will help doctors provide better personalized nutrition care as CF treatments continue to improve.
Cystic fibrosis is a serious disease that affects how the body digests food and absorbs nutrients. As treatments have improved, doctors need new guidance on how to feed CF patients properly. A team of international nutrition experts created updated recommendations covering important topics like diet quality, enzyme supplements, weight management, and feeding tubes. According to Gram Research analysis, these new expert opinions address gaps in current guidelines and will help doctors make better decisions about nutrition care for CF patients of all ages.
Key Statistics
An international expert consensus panel developed new nutrition recommendations for cystic fibrosis patients in 2026, addressing six key areas including enzyme supplementation changes with modulator therapy and management of overweight and obesity.
The expert recommendations were created by previous authors of the 2024 ESPEN-ESPGHAN-ECFS guidelines plus additional specialists, using a modified Delphi consensus method to ensure agreement on emerging nutrition issues in cystic fibrosis care.
The new expert guidance covers nutrition management in situations not adequately addressed by current guidelines, including CF patients using newer medications, those developing cancer, and older adults with cystic fibrosis.
The Quick Take
- What they studied: What nutrition recommendations should doctors follow for cystic fibrosis patients, especially for newer treatments and situations not covered by existing guidelines
- Who participated: An international team of nutrition experts and cystic fibrosis specialists who previously wrote official nutrition guidelines, plus additional experts in specific areas
- Key finding: Experts developed new recommendations on six important nutrition topics: diet quality, enzyme supplements with new CF drugs, managing weight gain, stopping tube feeding, nutrition during cancer treatment, and feeding older CF patients
- What it means for you: If you or a loved one has cystic fibrosis, your doctor may now have better guidance for personalized nutrition care. These recommendations are especially helpful for patients using newer CF medications or facing situations not covered by older guidelines.
The Research Details
A team of international nutrition experts who had previously written official cystic fibrosis nutrition guidelines came together to identify important nutrition topics that weren’t adequately covered by current guidelines. They recruited additional specialists with expertise in specific areas like cancer nutrition and care for older adults. The team created written statements about each topic and then used a modified Delphi process—a method where experts vote on recommendations multiple times until they reach agreement—to build consensus on the best approaches.
This approach was chosen because cystic fibrosis care is changing rapidly. New medications called modulators are transforming how CF is treated, and doctors need updated guidance to handle situations these new treatments create. The expert consensus method allows for faster updates than traditional guideline development, which can take years.
The final recommendations were reviewed and approved by the European Cystic Fibrosis Society’s Nutrition Group, ensuring they represent current expert thinking across Europe and internationally.
Cystic fibrosis treatment has changed dramatically in recent years. Newer medications work better than older treatments, but they change how patients’ bodies work—including how they digest food and gain weight. Doctors need current guidance to handle these new situations. This expert consensus provides that guidance while the formal international guidelines are being updated, which can take several years.
This paper represents expert opinion from recognized international specialists in cystic fibrosis nutrition. The authors previously wrote official guidelines, giving them credibility. The use of a structured consensus method (modified Delphi) strengthens the recommendations. However, this is expert opinion rather than research testing specific treatments, so recommendations are based on clinical experience and existing evidence rather than new experimental data. The paper serves as a bridge until formal guidelines are updated.
What the Results Show
The expert panel identified six key areas needing new guidance. First, they addressed diet quality—what CF patients should actually eat to stay healthy, beyond just getting enough calories. Second, they examined how pancreatic enzyme supplements should be used differently now that new CF medications are available, since these drugs change how the pancreas works. Third, they tackled the growing problem of overweight and obesity in CF patients, which is becoming more common as treatments improve and patients live longer.
Fourth, the experts provided guidance on when and how to stop tube feeding—something that wasn’t clearly addressed before. Fifth, they addressed nutrition support for CF patients who develop cancer, a situation that requires special consideration. Finally, they provided recommendations for nutrition care in older CF patients, a growing population that previous guidelines didn’t adequately address.
Each recommendation was developed through expert discussion and consensus voting, ensuring that the final statements represent agreement among specialists from multiple countries. The recommendations are designed to complement—not replace—existing official guidelines while addressing real clinical situations doctors face today.
The paper emphasizes that CF nutrition care must be individualized. What works for one patient may not work for another, depending on their specific situation, age, and which CF medications they’re taking. The experts also highlighted that nutrition care should involve a team including doctors, dietitians, and the patient themselves. The recommendations stress the importance of monitoring patients regularly to see if nutrition strategies are working and adjusting them as needed.
The 2024 ESPEN-ESPGHAN-ECFS guidelines that these experts helped write are the most recent official nutrition guidelines for CF. However, CF care is evolving so quickly that gaps have already appeared. This expert opinion paper fills those gaps by addressing topics like modulator therapy effects on nutrition, which is too new to be thoroughly covered in the 2024 guidelines. These recommendations will likely form the basis for the next official guideline update.
This paper presents expert opinion rather than research testing specific nutrition interventions. The recommendations are based on clinical experience and existing evidence, but not on new experimental studies. Some recommendations may need adjustment as more research becomes available. Additionally, the paper focuses on European and international expert perspectives, so recommendations may need adaptation for different healthcare systems or populations. The recommendations should be applied by qualified nutrition professionals who understand individual patient needs.
The Bottom Line
If you have cystic fibrosis or care for someone with CF, discuss these emerging recommendations with your CF care team, especially if you’re using newer CF medications (modulators), experiencing weight changes, or facing situations like cancer treatment. Work with your CF dietitian to develop a personalized nutrition plan based on your specific situation. High confidence: These recommendations come from recognized international experts. Moderate confidence: Some recommendations are based on clinical experience rather than large research studies.
CF patients and their families should be aware of these recommendations, especially those using newer CF medications. Healthcare providers caring for CF patients—including doctors, dietitians, and nurses—should review these recommendations to update their practice. People with CF who are older, overweight, or facing special situations like cancer treatment should particularly discuss these topics with their care team. These recommendations are less relevant for people without CF.
Changes in nutrition care may take weeks to months to show benefits, depending on what’s being adjusted. Weight changes typically become noticeable within 4-8 weeks. Improvements in energy and overall health may take longer. Regular monitoring with your CF care team helps track whether nutrition changes are working.
