- Abstract
In this article we discuss the physiological bases of polyunsaturated fatty acids (PUFAs) from n-6 and n-3 families and their end products: arachidonic acid (AA) and docosahexaenoic acid (DHA), respectively, to identify their importance in the fetal stage such as critical structural functions at 40 weeks of gestation. PUFA deficit is related to pathologies in preterm infants who did not achieve adequate accretion such as retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), and bronchopulmonary dysplasia (BPD), among others. In addition, studies evaluating the effect of supplementation with different concentrations of PUFAs on neurological and visual function and growth in neonates are analyzed. We also address the needs of DHA and AA at this stage of life and compare the enteral intake achieved by human milk feeding and the different formulas for preterm and term infants. DHA concentration in breast milk is highly variable and its contribution may be insufficient in neonates. Preterm infant formulas can meet international recommendations of DHA and AA issued by different organizations but, due to preterm birth, these infants have scarce tissue reserves but increased requirements for these fatty acids. Thus, enteral intake using current supplemental formula feeding appears to be insufficient. The final recommendation is to feed neonates with human milk by offering information to mothers regarding food sources with high DHA content, especially in the case of preterm babies.
