A team of researchers, from the University of Newcastle upon Tyne in England and Denmark, found the natural pesticide falcarinol reduced the risk of cancer developing in rats by one third.

Although experts have recommended that people eat carrots for their anti-cancer properties, it has not been known exactly what component of the vegetable has this effect.

The study results, published today in the Journal of Agricultural and Food Chemistry, are significant as they could contribute to healthy eating advice for consumers and recommendations for growers and may eventually aid the development of anti-cancer drugs.

Falcarinol protects carrots from fungal diseases, such as liquorice rot that causes black spots on the roots during storage. The scientists investigated the compound after a previous published study suggested it could prevent the development of cancer.

The research team carried out tests on 24 rats with pre-cancerous tumours in laboratory conditions. They divided them into three groups and fed them different diets.

The team found that, after 18 weeks, rats who ate carrots (the popular orange variety) along with their ordinary feed and the group which consumed falcarinol with their feed - in a quantity equal to that contained in the carrots - were one third less likely to develop full-scale tumours than the rats in the control group.

Dr Kirsten Brandt, a senior lecturer with Newcastle University's School of Agriculture, Food and Rural Development, carried out the research with the University of Southern Denmark and the Danish Institute of Agricultural Sciences. She said: "We already know that carrots are good for us and can reduce the risk of cancer but until now we have not known which element of the vegetable has these special propert
