What nutritional adjustment is recommended for patients with cystic fibrosis?

Patients with cystic fibrosis (CF) require increased caloric intake due to the malabsorption of nutrients and the increased energy expenditure associated with their condition. The pancreatic insufficiency often seen in individuals with CF leads to difficulties in digesting and absorbing fats, proteins, and carbohydrates, resulting in weight loss or difficulty maintaining a healthy weight.

To meet their nutritional needs adequately, it is generally recommended that patients with CF increase their caloric intake significantly—by about 130% or more of the standard caloric requirements for healthy individuals. This increase helps to compensate for nutrient losses and supports growth and development, especially in children and adolescents with CF. A high-calorie, high-fat diet is often beneficial, as these patients need more energy-dense foods to achieve proper nutrition and weight gain.

The other options do not align with the nutritional needs of CF patients. Reducing caloric intake or eliminating carbohydrates would further compromise their nutritional status, while introducing a high-fiber diet might not address the pressing need for increased caloric and fat intake. Thus, the recommendation for a significant increase in caloric intake is essential for managing CF effectively.
