Broccoli may combat prostate cancer by altering the genes involved in tumour growth, a study has shown.
Scientists made the discovery after adding either peas or broccoli to the diets of two groups of men for a year. They then analysed tissue samples from the men using technology that gauges the activity of thousands of genes. The results showed that a diet rich in broccoli produced changes in gene activity that were likely to stop or slow cancer growth.
Professor Richard Mithen, from the Institute of Food Research in Norwich, said: 'This is the first study providing experimental evidence that diets rich in cruciferous vegetables may reduce the risk of prostate cancer.'
Cruciferous vegetables are a family that includes broccoli, Brussels sprouts, cabbage, cauliflower and kale. Before the study it was already known that eating as little as one portion of broccoli every week can reduce the risk of prostate cancer and lessen the chances of confined cancer becoming more aggressive.
The research also confirmed that men with a gene called GSTM1 benefit most from eating broccoli, and suggested that men without the gene would have to eat more broccoli to get the same benefit.
