Clinical Trial Summary

The purpose of this study is to measure protein turnover rates in preterm infants.

Description:

After being informed about the study and potential risks, all parents giving written informed consent the principal investigator will determine the eligibility for study entry. Patients who met the eligibility requirements will be randomized in a double-blind manner in a 1:1 ratio to fortified breast milk with higher fat composition to fortified breast milk with higher carbohydrate composition. Both groups will receive a stable protein composition. The participants will receive the intervention for 3 consecutive weeks.
