Fish oils can transform the behaviour of disruptive teenagers, a study has revealed.
Youngsters were calmer and better able to concentrate after taking daily supplements for three months.
They were also less impulsive and kinder towards their parents, according to the research, which provides the clearest evidence yet of the benefit children receive from fish oils.
The findings add to the evidence that improving children's nutritional intake can calm their behaviour and even boost brainpower.
