Final answer:
Patients with cystic fibrosis require a diet that is high in calories and fats to compensate for poor nutrient absorption and to ensure adequate nutrition. Carbohydrates are a vital part of their diet, providing essential energy for organ and tissue function.
Step-by-step explanation:
The appropriate diet for a patient with cystic fibrosis should be high-kcalorie, high-fat. Patients with cystic fibrosis have difficulty absorbing nutrients, including fatty acids, due to problems with pancreatic enzyme production, leading to malnutrition and poor growth. Therefore, a diet that is high in calories and fats as well as supplemented with pancreatic enzymes is important to ensure that they receive adequate nutrition.
Carbohydrates are necessary for biological functions and are an important dietary component. They are the body's main source of energy and are crucial for the proper functioning of organs, tissues, and cells. Consuming adequate amounts of carbohydrates helps provide the energy needed for day-to-day activities and organ function.
