Papamichael MM, et al. - Researchers performed this literature analysis to determine the role of fish intake, the main dietary source of long chain omega-3 fatty acids, on asthma in children. They analyzed data from relevant publications. They identified a total of 1119 publications, of which 23 studies were finally reviewed. Findings revealed attenuated asthma and wheeze in children up to 4.5 years old as a result of the introduction of fish early in life (6-9 months) and regular consumption of all fish (at least once a week). In this meta-analysis of observational studies, they also found that fatty fish intake may be beneficial in older children.
