The calorie intake of children with cystic fibrosis is about 150 percent higher than a normal diet, so proper nutrition is a key focal point of our team at the CF Center at Johns Hopkins All Children's Hospital.


Nutrition is a key component in the overall health of children with cystic fibrosis. Children with CF need extra calories and a high fat diet to sustain a healthy weight for growth, maximize lung capacity, build muscle strength for breathing and support the immune system. 

Calorie intake is at about 150 percent of a normal diet. There is also difficulty with absorption of fats and fat soluble vitamins (A, D, E, and K), so supplementation of these vitamins is often necessary. 

Enzymes are often taken with each meal and snack to help break down the fats and absorb the calories from fat. Many cystic fibrosis children are pancreatic insufficient, therefore lacking the enzymes to help break down food. Monitoring stools that appear greasy, malodorous or bulky give key indications about the way the body is digesting food and nutrients.

Ways to help maintain a healthy diet and weight include:

  • High calorie supplemental drinks
  • High-fat diet
  • Duocal added to food
  • Medium-chain triglycerides (MCT) oil
  • Salt supplementation
  • Vitamin supplementation
  • Our dietitian will assist you in making the healthiest choices that are best for your child.

What is a G-tube?

A gastrostomy tube (also called a G-tube) is inserted through the abdomen that delivers nutrition to the stomach. The technique is one of the ways doctors can make sure kids get the fluid and calories they need. Learn More.

What are enzymes used for?
