摘要
The early dietary supply of long-chain polyunsaturated fatty acids (LCPUFA) might contribute to the higher developmental scores of children breast-fed as infants. Preterm infants' improved visual acuity and neurodevelopmental performance correlate with dietary supplementation of LCPUFA in amounts similar to those that breast-fed infants receive and studies of term infants report similar effects with LCPUFA supplementation. Whether term infants may benefit from LCPUFA-unsupplemented formulas with higher amounts of α-linolenic acid (n−3 LCPUFA precursor) is controversial. With the onset of weaning, the question of the exact quantity and quality of which dietary lipids to give for prevention purposes is still open. Early dietary intervention studies of weaned children under 2 years are in progress in populations at high risk for early cardiovascular disorders. Preliminary results indicate that these interventions, while preventing an age-dependent increase in blood lipid levels, are safe for growth, but the balance of all the macronutrients should be carefully considered before general recommendations can be made.
