Ministers are awaiting the results of a review by the Food Standards Agency, which looks at the effects of omega 3 and 6 fish oil on the performance and behaviour of children in schools.
Education secretary Alan Johnson said, 'The Government is committed to ensuring that children are provided with the healthy food and nutrients they require during the school day, not just to aid their physical health, but to ensure they can study hard and behave well.
'The Food Standards Agency is currently conducting a systematic review of research looking at the effect of nutrition and diet on performance and behaviour of children in schools. This includes investigating studies that have used omega 3 and 6 fish oil supplements in schools.'
Meanwhile, the DfES said that new minimum standards for school food, backed up by a 220m investment, stipulate regular inclusion of oily fish in school menus.
