Purple ‘super tomato’ that can fight against cancer

It looks like a cross between an orange and a black pudding, but this genetically modified purple ‘super tomato’ could be the latest weapon in the fight against cancer.

The fruit, which tastes and smells like a normal red tomato, has been given two genes from a snapdragon flower that produce the dark colour.

The distinctive hue is created by antioxidant pigments that protect against diseases including cancer, heart problems and diabetes.

British scientists behind the crop believe their purple tomato is the respectable face of genetic modification and could help convince the public of the benefits of GM food.

But critics say the potential health benefits are a distraction from the harmful environmental side effects of GM farming.

The tomato – developed by the John Innes Centre in Norwich – contains high concentrations of anthocyanins, pigments found in blackberries and cranberries.

Anthocyanins are chemicals called flavonoids which mop up potentially harmful oxygen molecules in the body. Although they are produced naturally by tomato plants, they are normally found only in the leaves.

The scientists transferred the genes from the snapdragons using specially adapted bacteria.
