Pancreatitis, characterized by inflammation of the pancreas, presents unique nutritional challenges in pediatric patients. This article consolidates current knowledge and expert recommendations to provide a comprehensive guide for dietary management of pediatric pancreatitis, encompassing both acute and chronic forms. The aim is to equip healthcare providers and families with the information needed to optimize nutritional support and improve outcomes for children affected by this condition.
Understanding Pediatric Pancreatitis
Pancreatitis in children can manifest as acute pancreatitis (AP), a sudden inflammation of the pancreas, or chronic pancreatitis (CP), a long-term condition characterized by progressive pancreatic damage. The incidence of pancreatic diseases in children varies widely. Acute recurrent pancreatitis (ARP) is also a consideration.
Nutritional Considerations in Acute Pancreatitis (AP)
Early Enteral Nutrition in Mild to Moderate AP
Early initiation of enteral nutrition (EN) is considered safe and feasible in pediatric patients with mild to moderate AP. It's not associated with increased pain or elevated serum lipase levels. Enteral nutrition, when started within 48 hours of admission, is linked to several benefits, including:
- Significant reduction in the length of hospital stay
- Reduced progression to severe acute pancreatitis (SAP)
- Decreased need for ICU transfers
- Increased weight gain at follow-up
These findings underscore the importance of early nutritional support in managing pediatric AP.
Enteral vs. Parenteral Nutrition
Enteral nutrition (EN) is generally preferred over parenteral nutrition (PN) in patients with AP. Studies suggest that early EN is beneficial in both adults and children with mild AP.

Route of Enteral Feeding
While some studies have explored the benefits of jejunal feeding, gastric feeding is considered safe and well-tolerated in AP.
Dietary Recommendations for Acute Pancreatitis
Initial Dietary Management
Historically, "conventional fasting or NPO" (nothing per oral) was a common practice in AP management. However, current evidence suggests that early initiation of a normal diet (within 48 hours) is feasible in most cases, with lower rates of progression to severe acute pancreatitis.
Transitioning to Oral Feedings
Park et al. and older children with AP at Yale-New Haven Children’s Hospital transitioned from NPO to oral feedings.
Low-Fat Diet
A low-fat diet is often recommended, as it reduces the burden on the pancreas to produce enzymes for fat digestion. A low-fat diet generally contains no more than 30g of fat per day.
Importance of Whole Foods
Focus on eating whole foods like fresh fruits and vegetables, lean proteins, and whole grains.

Foods to Avoid
High-fat foods can worsen pancreatitis symptoms. Common foods to avoid include:
- Bacon, sausage, and fatty cuts of beef and pork
- High-fat dairy products such as whole milk, cream cheese, and full-fat yogurt
- Fried and greasy foods
- Processed foods, including packaged snacks, frozen meals, and processed meats
Sample Meal Plan
A well-structured 7-day meal plan can help manage pancreatitis symptoms by providing a concrete nutrition guide.
Nutritional Considerations in Chronic Pancreatitis (CP)
Nutritional management in CP aims to address malnutrition, malabsorption, and nutrient deficiencies.
Monitoring of Growth Parameters
Regular monitoring of growth parameters, including weight, height, and BMI, is crucial in children with CP.
Caloric Intake
Children with CP may have higher resting energy requirements compared with healthy subjects. They may need a higher proportion of calories from carbohydrates.

Fat Intake
Fat intake should be carefully managed, and the proportion of MCTs may need to be limited to prevent ketoacidosis.
Vitamin and Mineral Deficiencies
Fat-soluble vitamin deficiencies are common in patients with CP. Regular monitoring of vitamin levels, including 25-hydroxyvitamin D, is recommended. Selenium and vitamin B12 levels may also be low in patients with CP. Routine zinc monitoring is not generally recommended.
Bone Health
Bone health is an important consideration in children with CP, as they may be at risk for osteopenia and osteoporosis. Follow-up DEXA depends on results of the baseline study.
Pancreatic Enzyme Replacement Therapy (PERT)
PERT is well-studied in CF, but its role in children with CP is less clear. Doses are adjusted based on effect (clinical, stool, growth).
Fecal Elastase-1 (FE-1) Testing
Fecal elastase-1 (FE-1) is widely used for the diagnosis of EPI.
Diabetes Management
The effect of diabetes on nutritional status in CP is less clear.
Specific Dietary Recommendations for Chronic Pancreatitis
High-Protein, Nutrient-Dense Diet
Patients with chronic pancreatitis benefit from high protein, nutrient-dense diets that include fruits, vegetables, whole grains, low fat dairy, and other lean protein sources.
Small, Frequent Meals
Encourage small and frequent meals that include a healthy balance of fat, proteins, and carbohydrates.
Vitamin and Mineral Supplementation
Vitamin therapies should be based on annual blood tests.
Alcohol Abstinence
If pancreatitis was caused by alcohol use, you should abstain from alcohol.
Additional Considerations
Antioxidants
Supplementing children with ARP with antioxidants may provide benefit, but further research is needed.
Probiotics
The use of probiotics is not consistently shown to be beneficial.
The Role of a Multidisciplinary Team
Effective management of pediatric pancreatitis requires a multidisciplinary approach, involving gastroenterologists, nutritionists, and other specialists.
Gaps in Knowledge and Future Research
Despite advancements in understanding pediatric pancreatitis, several gaps in knowledge remain. Areas in need of research include:
- The impact of specific dietary interventions on clinical outcomes
- The optimal duration of low-fat diets
- The role of antioxidants and probiotics
- The long-term effects of pancreatitis on nutritional status and bone health
