One of the cornerstones of a healthy life is good nutrition. Many people with CF have exocrine pancreatic insufficiency (EPI), meaning it’s difficult for your pancreas to make enzymes (chemicals that break down food). Your body needs those enzymes to absorb calories, vitamins, and minerals from food.
This makes it hard for you to digest your food or stay at a healthy weight. Once you know what you should be eating, you can help control how good you feel.
