Fish Oil Can Reduce Infections in Healthy Children

In a placebo-controlled study of 180 healthy Thai schoolchildren, results indicate that supplementation with fish oil may reduce the frequency and duration of illness, particularly those involving the upper respiratory tract. The children received fish oil (200 mg EPA and 1 g DHA per day) or placebo, five days per week for a period of 6 months. At intervention end, children in the fish oil-supplemented group showed fewer episodes and shorter duration of illness (mainly upper respiratory tract) than the placebo group. Additionally, plasma transforming growth factor (TGF)-beta1 concentrations were lower in the fish oil group, compared with the placebo group. Thus, the authors of this study conclude, “Very long-chain omega-3 PUFAs reduce illness, mainly infections, in healthy Thai schoolchildren.”
