Super-healthy tomatoes full of a disease-fighting 'miracle ingredient' have been created by British scientists.
The designer fruits are bursting with resveratrol, a chemical found in red wine that is credited with a host of health benefits from warding off cancer to keeping the mind sharp.
Resveratrol may even be capable of extending life. However the amount found in grapes is low and making the chemical in the lab in large quantities would be prohibitively expensive.
But a single tomato contains as much resveratrol as 50 bottles of wine, thanks to the addition of two genes by the researchers at the John Innes Centre in Norwich, the journal Nature Communications reports.
Researcher Dr Yang Zhang said that as tomatoes are so easy to grow, the health-giving compound could quickly be churned out on an industrial scale.
