A schoolgirl has to eat olive oil with everything - otherwise she could suffer from life-threatening seizures, The Daily Mail reports.

Light-weight Amy Paterson, nine, has a rare, incurable genetic condition, which means her brain can't receive enough nourishment from a normal diet.

As a result she must consume three times as much fat as her friends and drink as much double cream or olive oil in one meal as an adult would consume in a day.

Amy manages to attend school and live a normal life, but her devoted mum Michelle and dad Allan, both 44, have to closely monitor her 1,482 calorie, six meal-a-day diet.

There are only 25 people diagnosed with the condition, known as 'glut1 deficiency syndrome', in the UK, with 100 sufferers in the world.
