Background:意大利農(nóng)民展示了一種據(jù)說(shuō)能減慢衰老過(guò)程的正方形西紅柿。農(nóng)民協(xié)會(huì)說(shuō)，這種西紅柿含有大量的能減少人體細(xì)胞損傷的自然元素。

The new tomato was grown without genetic modification in the regions of Emilia Romagna and Lombardy.

Italy's Farmers Union, which organised its public launch, said the tomato is full of lyco-pene - a red pigment that contains antioxidants.

They are strong neutralisers of the free radicals in the body which can damage human cells.

The union says the tomato could help slow the ageing process and may also be effective in preventing some cancers and heart disease.

A number of other scientific studies have pointed to the therapeutic benefits of lyco-pene.

One British supermarket chain has already marketed its own brand of what are now known as super tomatoes.
