The Source of “Lost Calories” from Fortified Breast Milk
MCT1 oil is frequently chosen as fortifier for human milk (HM) feeds for the very premature infant because it improves caloric density without increasing the osmotic load of the feed. In practice, however, these infants who apparently are receiving adequate calories do not demonstrate the expected growth. We have therefore investigated whether fat might be lost because of adherence to feeding sets in the prevailing methods of MCT supplementation. Forty feeding sets, collected from infants on feeds of 3 different compositions, were analyzed for amount of residual fat (measured as % of total fat in feed by gravimetry). The fatty acid composition (FA) of the fat residue was analyzed by gas chromatography.
