Use of fish oil in pregnancy may prevent asthma, respiratory infections in offspring

KEY POINT

Use of long-chain polyunsaturated fatty acids (LCPUFAs) derived from fish oils during the third trimester of pregnancy resulted in a 30% relative reduction in the risk of persistent wheezing or asthma in offspring during the first 5 years of life and was associated with a reduced risk of respiratory infections compared with women who did not receive these supplements, according to results of a large, randomized trial published in the New England Journal of Medicine.
