Recent advances in asthma

Low intake of n-3 long-chain polyunsaturated fatty acids (LCPUFAs) during pregnancy may be associated with an increased risk of childhood wheezing and asthma. Most previous trials of this issue have been underpowered, with inconclusive results. This randomized controlled trial with long-term follow-up evaluated the effects of n-3 LCPUFA supplementation during pregnancy on the risk of wheeze and asthma in offspring. At 24 weeks' gestation, 736 pregnant women were assigned to supplementation with fish oil, containing 2.4 g of n-3 LCPUFA, or olive oil.
