According to Gram Research analysis, exclusive enteral nutrition and the Crohn’s disease exclusion diet work equally well for treating Crohn’s disease in children, with both achieving remission in approximately 75-77% of kids within 6 weeks. A 52-week study of 159 children found no significant differences between the two approaches in symptom relief, inflammation reduction, medication needs, or long-term outcomes, meaning families can choose based on what’s most practical for their lifestyle.
A new 52-week study compared two popular nutritional approaches for treating Crohn’s disease in children: exclusive enteral nutrition (a special liquid diet) and the Crohn’s disease exclusion diet (CDED, which removes certain foods). Researchers followed 159 children and found that both approaches worked equally well at reducing symptoms and inflammation. About 75-77% of kids in each group achieved remission (symptom relief) within 6 weeks, and both groups maintained similar results throughout the year. This Gram Research analysis suggests parents and doctors have flexibility in choosing which dietary approach works best for their child’s lifestyle and preferences.
Key Statistics
A 52-week cohort study of 159 children with Crohn’s disease found that 77% of children on exclusive enteral nutrition and 75% on the CDED diet achieved clinical remission within 6 weeks, with no statistically significant difference between approaches.
According to research reviewed by Gram, treatment adherence rates were nearly identical between the two dietary approaches, with 89% of families successfully following exclusive enteral nutrition and 88% adhering to the CDED over the 52-week study period.
A 2026 study comparing nutritional therapies for pediatric Crohn’s disease found that both exclusive enteral nutrition and the CDED showed comparable rates of inflammation marker normalization, with C-reactive protein normalizing in 43-46% of children by week 6.
Over 52 weeks of follow-up, children treated with either exclusive enteral nutrition or the CDED showed no significant differences in disease flare-ups, need for additional medications, hospitalizations, or surgical interventions, suggesting both approaches provide sustained benefit.
The Quick Take
- What they studied: Whether a liquid-only diet or a modified food-based diet works better for helping children with Crohn’s disease feel better and reduce inflammation
- Who participated: 159 children diagnosed with Crohn’s disease between 2014 and 2023. About 75 kids tried the liquid diet approach, and 84 tried the food-based diet approach. Both groups had similar disease severity at the start
- Key finding: Both diets worked almost identically well: 77% of kids on the liquid diet and 75% on the food-based diet felt better within 6 weeks, with no meaningful differences in inflammation markers or long-term outcomes over the full year
- What it means for you: If your child has Crohn’s disease, either dietary approach can help achieve remission. The choice can be based on what’s easier for your family to follow, your child’s preferences, and what your doctor recommends. Neither approach is clearly superior, so personalization matters
The Research Details
Researchers looked back at medical records of children with Crohn’s disease treated between 2014 and 2023. They divided the children into two groups: those who received exclusive enteral nutrition (EEN)—a special liquid formula containing all necessary nutrients—and those who followed the Crohn’s disease exclusion diet (CDED)—a regular food diet that removes certain ingredients thought to trigger inflammation. Both groups were followed for 52 weeks (one full year) to track how well they did.
The researchers measured success using multiple methods: asking if kids felt better (clinical remission), checking blood inflammation markers (C-reactive protein), measuring stool inflammation markers (fecal calprotectin), and using a special scoring system to assess gut lining healing. They also tracked whether kids needed additional medications, hospitalizations, or surgery during the year.
This type of study, called a historical cohort study, is useful because it looks at real-world treatment outcomes over a long period. However, it relies on existing medical records rather than a carefully controlled experiment, which means some information might be incomplete or influenced by how doctors chose to treat each child.
Understanding which dietary approach works best helps doctors and families make informed decisions about Crohn’s disease treatment. Since both approaches require significant lifestyle changes, knowing they’re equally effective means families can choose based on what’s practical for them rather than assuming one is always better. This research also validates the CDED as a legitimate alternative to the more restrictive liquid-only diet
This study has several strengths: it included a reasonably large group of children (159), followed them for a full year, and measured multiple indicators of disease improvement. The two groups had similar disease characteristics at the start, which makes comparison fair. However, the study looked backward at existing medical records rather than randomly assigning children to treatments, so some differences between groups might exist that weren’t measured. The high adherence rates (88-89%) suggest both diets were tolerable for most families
What the Results Show
At the 6-week mark, both dietary approaches showed nearly identical success rates. In the exclusive enteral nutrition group, 77% of children achieved clinical remission (felt significantly better), compared to 75% in the CDED group—a difference so small it could easily be due to chance. Treatment adherence was also remarkably similar, with 89% of families sticking with the liquid diet and 88% following the food-based diet.
Blood inflammation markers (C-reactive protein) normalized in 43% of the EEN group and 46% of the CDED group by week 6. Stool inflammation markers (fecal calprotectin below 150 mcg/g) normalized in 35% of the EEN group and 34% of the CDED group. A specialized scoring system measuring gut lining healing showed improvement in 52% of the EEN group and 69% of the CDED group, though this difference wasn’t statistically significant.
Over the full 52-week follow-up period, the two groups remained virtually identical. There were no meaningful differences in disease flare-ups, need for additional medications (corticosteroids or biologics), hospitalizations, or surgical interventions. Both groups maintained their improvements throughout the year, suggesting both approaches provide sustained benefit.
The study found that treatment adherence was surprisingly high for both approaches, with nearly 9 out of 10 families successfully following their assigned diet. This is important because it shows both diets are practical enough for real families to maintain. The similar rates of additional medication use suggest neither diet alone was insufficient for most children—when kids needed extra help, both groups required it at similar rates. The comparable hospitalization and surgery rates indicate both approaches prevented serious complications equally well
Previous research has suggested that exclusive enteral nutrition is highly effective for Crohn’s disease in children, with remission rates around 70-80%. This study confirms those results while also validating the CDED as an equally effective alternative. The CDED is newer and less studied than EEN, so this head-to-head comparison is valuable. The findings align with growing evidence that multiple dietary approaches can work for Crohn’s disease, rather than one single ‘best’ method
This study looked backward at medical records rather than randomly assigning children to diets, which means doctors may have chosen different treatments based on factors not measured in the study. Some children may have received additional treatments not captured in the records. The study included children treated over a 9-year period, during which medical practices and available medications changed. Different doctors may have measured inflammation markers at different times or using different methods. The study didn’t measure quality of life, which is important since the liquid diet is more restrictive than the food-based diet. Finally, results may not apply to all children with Crohn’s disease, particularly those with more severe disease
The Bottom Line
For children newly diagnosed with Crohn’s disease, either exclusive enteral nutrition or the CDED can be used as a first-line treatment to achieve remission, with high confidence based on this research. The choice should be made together with your child’s gastroenterologist based on: (1) your family’s ability to follow each approach, (2) your child’s food preferences and social needs, (3) access to specialized formulas if choosing EEN, and (4) any other medical conditions your child has. Both approaches require professional supervision and monitoring
This research is most relevant for families with children recently diagnosed with Crohn’s disease who are considering dietary treatment options. It’s also important for pediatric gastroenterologists making treatment recommendations. Parents should discuss these findings with their child’s doctor rather than self-treating. This research applies to children with active Crohn’s disease seeking remission; it may not apply to adults or to maintaining remission after it’s achieved
Based on this study, most children (about 75-77%) can expect to feel significantly better within 6 weeks of starting either diet. Full normalization of inflammation markers may take longer—only about 35-46% showed complete normalization by week 6. Sustained improvement appears to continue throughout the first year. Individual results vary, and some children may respond faster or slower than average
Frequently Asked Questions
What’s the difference between exclusive enteral nutrition and the CDED diet for Crohn’s disease?
Exclusive enteral nutrition (EEN) is a liquid formula diet containing all nutrients, while CDED is a regular food diet that removes certain ingredients thought to trigger inflammation. This study found both approaches work equally well for children with Crohn’s disease, achieving remission in about 75-77% within 6 weeks.
How long does it take for a Crohn’s diet to work in children?
Most children (approximately 75-77%) experience significant symptom improvement within 6 weeks of starting either exclusive enteral nutrition or the CDED. However, complete normalization of inflammation markers may take longer, with only 35-46% showing full normalization by week 6.
Can kids stick with these Crohn’s disease diets long-term?
Yes, this study found high adherence rates for both approaches: 89% for exclusive enteral nutrition and 88% for the CDED over 52 weeks. This suggests both diets are practical enough for families to maintain, though individual tolerance varies.
Which diet should my child with Crohn’s disease try first?
Since both approaches work equally well, the choice depends on your family’s preferences and circumstances. Discuss with your child’s gastroenterologist which is more practical for your lifestyle, your child’s food preferences, and access to specialized formulas if needed.
Do kids need additional medications if they follow these diets?
This study found no significant differences between the two dietary approaches in the need for additional medications like corticosteroids or biologics. Some children may still require additional treatment, which your doctor can determine based on individual response.
