Most children don’t eat enough of the omega-3 essential fatty acids found in oily fish.We know that omega-3s are essential ‘building blocks’ for brain development, and several recent high profile studies say a lack of omega-3s could cause bad behaviour. Interim results from a trial of 60 children in Durham show that the behaviour of more than half the children involved has improved since they began to take supplements. But Dr Lunn says more research is needed before we hail omega-3s as a miracle cure for bad behaviour. “However, current guidelines state that women of reproductive age and girls should aim for one to two portions of oily fish per week. Those women past reproductive age, boys and men should have one to four portions every week,” she says. “Supplements are an alternative source if you don’t like oily fish.”
