Cystic Fibrosis Diet

It is extremely important for people with cystic fibrosis(CF) to establish a specific cystic fibrosis diet. People with CF have difficulty in absorbing nutrients from their food. This is due to mucus building up and blocking pancreatic enzymes from reaching the digestive tract. People with cystic fibrosis also lose a lot more salt from their sweat and become dehydrated more easily. This results in them needing much more calories, fats, salts, and water from their diet.

The dietary needs also depend on the stage of life. Younger children and teens with cystic fibrosis have a stronger need to consume more calories to support healthy growth. This includes calcium, proteins, zinc, and food rich in fat soluble vitamins (A, D, E, & K).

Adults with cystic fibrosis need a healthy diet that allows them to maintain an active lifestyle. Since the pancreatic enzymes cannot reach the digestive tract, one of the most important aspects of diet for cystic fibrosis is oral supplementation of enzymes. These aid in the absorption of nutrients and promote a longer, healthier life.

There are many considerations to diet with cystic fibrosis. But the three biggest factors to healthy living are:

  • Caloric Intake
  • Vitamin/Enzyme Supplementation
  • Hydration

The reduced nutrient absorption by the digestive tract and increased loss of salt through sweat make it incredibly important for people with cystic fibrosis to consume enough calories and enzymes as well as maintain proper hydration.

Cystic Fibrosis Vitamins & Enzymes

The obstruction of pancreatic ducts by mucus buildup in cystic fibrosis prevents essential enzymes from reaching the digestive tract. These enzymes are integral in facilitating the absorption of fat soluble vitamins (A, D, E, & K). Supplementing the diet with these vitamins and consistent intake of enzymes to aid in absorption is essential for cystic fibrosis.

Cystic Fibrosis & Staying Hydrated

People with cystic fibrosis release a much higher quantity of salt in their sweat. Since the feeling of dehydration is signaled in the body by an imbalance of water to salts, people with CF often do not realize that they are under hydrated. It is extremely important for people with cystic fibrosis to make sure they are getting enough water to replenish the salts that they losing in their sweat to remain hydrated and healthy.
