Sample text

Enteral formulas high in carbohydrate can lead to an increased production of carbon dioxide, which may exacerbate the pulmonary status of patients with advanced lung disease [87, 88]. In studies comparing the use of different formulas in CF patients, the formulas which were higher in fat and lower in carbohydrate resulted in lower carbon dioxide production, lower respiratory quotient (RQ), and lower minute ventilation compared to higher carbohydrate, lower fat formulas [88, 89]. Of note, due to the increased minute ventilation on the higher carbohydrate formulas, the patients studied were able to breathe off the additional carbon dioxide to avoid increased carbon dioxide retention and hypoxia [89].

It has been noted that the percentage of calories from fat may not correlate well with total calorie intake and overall nutritional status [70, 74]. Several investigators did not find an association between percent of calories provided by fat and the percentage of the recommended energy index consumed [74] or the percentage of ideal body weight [70]. Grams of fat consumed per day did positively correlate with total daily energy intake and percent ideal body weight, thus it was concluded that it would be more beneficial to set an actual daily fat gram goal for patients to achieve [70, 74].

Patients, especially those with high energy needs, may benefit from a diet higher in fat (approximately 35% of total calories). 5–2 times greater than the recommended daily allowance or ~15% of total calories. • There are no specific recommendations for carbohydrate provision and intake is generally adequate in people with CF. • With adequate enzyme intake, no clear benefit of medium chain fats or hydrolyzed proteins has been found compared to long chain fats except for in patients with additional digestive and/or allergic issues.
