Energy intakes in cystic fibrosis (CF) are affected by malabsorption, despite the use of enteric‐coated pancreatic enzymes. Relaxation of fat restrictions was introduced to aid consumption of a diet sufficient to compensate for malabsorption and help prevent malnutrition. We examined the energy intakes and losses of 50 CF patients on a normal fat intake (mean age 9.6 [s.d.=6.67] years, M:F ratio 33:17). Mean standard deviation scores for height and weight were –1.03 and –0.80, respectively. Nutrient balances were made by means of 7‐day weighed dietary inventories and 3‐day faecal collections. Mean metabolizable energy intake was 97.3 [s.d. 23.1)% RDA. Mean digestibility coefficient for energy was 0.89 (s.d. 0.07), reducing mean energy intakes to 91.9 (s.d. 24.0)% RDA. The results indicate that despite relaxation of dietary restrictions and the use of enteric‐coated pancreatic enzymes, energy intakes of CF patients are still inadequate. Closer monitoring of energy losses as well as intakes is required, to optimize growth and nutritional status in CF patients.
