Background: Some patients cannot feed orally and use enteral nutrition to meet their daily food needs. This study aimed to investigate the calories and macronutrients of enteral formulas prepared in Mashhad hospitals and to design blenderized tube feeding for hospitals.
Methods: Fifteen samples were taken from each hospital to measure the energy and macronutrients of enteral formulas of Mashhad hospitals. Fresh and natural foods were also used to design blenderized tube feeding.
Results: The present study showed that the calories of blenderized tube feeding prepared in the hospitals were between 81-97 kcal/100 mL and in commercial enteral formula between 80-96 kcal/100 mL. In addition, protein, fat, and carbohydrates of blenderized tube feeding prepared in hospitals were between 8-16%, 31-39, and 51-56%, respectively. Also, commercial enteral formula’s protein, fat, and carbohydrates in hospitals were between 13-15%, 30-35, and 49-55%, respectively. Energy, protein, fat and carbohydrate of blenderized tube feeding designed from fresh and natural foods were between 102-112 kcal/100 mL, 16-23%, 31-34%, and 45-51%, respectively.
Conclusion: The blenderized tube feeding prepared in hospitals and the commercial enteral formula did not meet the energy requirement of 1 kcal/mL. In addition, the energy and macronutrients of the blenderized tube feeding were used in the present study to design fresh and natural foods and were within the recommended range for patients.
