Challenges of matching human milk fatty acid patterns technically and functionally.
A vegetable oil fat blend resulting in formula major fatty acid levels similar to human milk is appropriate for infant feedings even though the palmitic acid may have a somewhat different positional distribution. Growth, bone mineral content, and visual acuity (as measured by the Teller acuity card procedure) achieved in normal infants consuming such formulas are at least as good as those from human milk. The quantitatively minor LC-PUFA levels may also be important in infant development and useful once safety of their sources has been adequately demonstrated. Such formula fat blends mimicking the major fatty acid profiles of human milk are appropriate for infants with relatively normal fat absorptive mechanisms including infants with allergy or inborn errors of metabolism. Formulas designed for such infants (e.g., extensively hydrolyzed protein products for allergic infants) do not need to have MCT oil included in the formulation which alters the fatty acid profile. On the other hand, those infants with immaturity, gastrointestinal disease, and/or fat malabsorption often do benefit by the inclusion of MCT oil in the fat blend of the formula.
