LCPUFAs have important roles to play in many functions including tissue development, organogenesis, the central nervous system (particularly vision), immune modulation and resolving inflammation. Correcting deficiencies in LCPUFAs, especially docosahexaenoic acid (DHA) and arachidonic acid (AA), in preterm infants has the potential to improve neurodevelopment and vision and perhaps even reduce some inflammatory morbidities. In this video, Dr Andrew McPhee talks about the role of DHA and AA in preterm nutrition.
