A school in Worcestershire has banned all additives from its meals to stop children behaving badly.

Barnabas first and middle school in Drakes Broughton banned 27 additives - including the yellow colouring in custard - during a two week trial.

Staff started the trial after discovering a study suggested one in four children have tantrums as a result of eating too many additives.

After two weeks staff say they noticed a marked improvement in pupils' behaviour

Sleeping better

Headteacher Charlie Lupton said children's concentration levels had also improved since the trial started.

"We carried out a survey of the parents to find out if they had noticed a difference in their children's behaviour," he said.

"More than 30% of parents noticed their children were better behaved during the trial and 18% said their children were sleeping better."

He said pupils had also commented on how much better their school meals tasted.
