Asthma is the most common chronic condition in childhood and we currently don’t know how to prevent it. It is possible that a poor diet (omega-3 fatty acids) may increase the risk of developing asthma, but until now most studies have taken ‘snap-shots’, measuring diet and asthma over a short period of time. Instead, we measured diet and then followed up children over many years to see who developed asthma and who didn’t. Whilst we cannot say for certain that eating more fish will prevent asthma in children, based on our findings, it would nevertheless be sensible for children in the UK to consume more fish, as few currently achieve recommended intake.
The study, published in the European Respiratory Journal, used data from a large UK birth cohort, Children of the 90s, which recruited mothers who were pregnant in the early 1990s and has been following up their offspring ever since. They analysed the association between intake of EPA and DHA from fish at 7 years of age (estimated by food frequency questionnaires) and incidence of new cases of doctor-diagnosed asthma at 11-14 years of age.
