Because of the rapid rate of growth during infancy, and the potentially deleterious effect of differences in the availability of dietary essential nutrients, growth is an important outcome variable in any study assessing a diet designed for infants. Nearly 10 yr after the first demonstration of reduced growth in preterm infants fed a fish oil‐enriched formula, there is very little additional information to confirm or refute the finding that long‐chain n−3 polyunsaturated fatty acid (LC‐PUFA) intake can modulate growth in infants. To evaluate the issue of a possible relationship between PUFA intake and growth of infants, we reviewed a total of 32 randomized studies, 13 in preterm infants and 19 in term infants. From the data published to date, it seems clear that long‐chain n−3 fatty acids can reduce growth achievement in preterm and term infants under some experimental conditions. However, the effect of n−3 PUFA supplementation on the growth of preterm and term infants appears to be minimal and of questionable clinical and/or physiologic relevance. Nonetheless, n−3 fatty acids have an effect on gene transcription, at least in some species, and this finding may provide important clues to the mechanism by which n−3 and n−6 fatty acids regulate growth.
