Food colours and hyperactivity
We funded research into possible links between food colours and hyperactivity in children. It found that consuming certain artificial food colours could cause increased hyperactivity in some children.
These artificial colours are:
sunset yellow FCF (E110)
quinoline yellow (E104)
carmoisine (E122)
allura red (E129)
tartrazine (E102)
ponceau 4R (E124)
Food and drink containing any of these six colours must carry a warning on the packaging. This will say ‘May have an adverse effect on activity and attention in children’.
We encourage manufacturers to work towards finding alternatives to these colours. Some manufacturers and retailers have already taken action to remove them.
It’s important to remember that hyperactivity can also be caused by other things. So being careful about what a child eats may help manage hyperactive behaviour but it may not stop it.
