Following on from research showing that omega-3s might not improve cognition in older people
a new study shows that they may not have much of an effect in children either. Researchers from the University of Wales studied 450 children between the ages of eight and ten in Newport, South Wales. Half of them were given omega-3 supplements while the rest were given a placebo. The children were given psychological assessments and teachers and parents reported on any changes they saw in their behaviour. Reading, spelling and coordination were largely unaffected by the omega-3 although it did produce an improvement in children's attention in class.
