Why is a high-calorie, high-protein diet prescribed for a child with cystic fibrosis?

• A. To support growth
• B. To prevent constipation
• C. To reduce respiratory infections
• D. To increase fat absorption

Answer: (A)

In cystic fibrosis, growth and development can be compromised because fat and protein are often poorly absorbed and energy needs are higher due to chronic lung disease and frequent infections. A high-calorie, high-protein diet provides the extra calories and amino acids necessary for normal growth, tissue repair, and maintaining weight, helping the child reach appropriate height and weight for age. This isn’t primarily about preventing constipation, reducing infections, or increasing fat absorption. Constipation isn’t the main goal of this diet, and while good nutrition supports immune function, the key reason for this plan is to meet the increased growth and energy needs. Fat absorption is typically improved with pancreatic enzyme replacement, not by simply eating more fat.
