Greens Are Good
BROCCOLI may combat prostate cancer by altering the activity levels of genes involved in tumour growth, a study has shown.
Scientists made the discovery after adding either peas or broccoli to the normal diets of two groups of men for a year.
During the study tissue samples were removed from the men's prostate glands and analysed to gauge the activity of thousands of genes.
The results showed a broccoli-rich diet produced changes in gene activity, or expression, that were likely to prevent or hinder cancer growth and inflammation in the prostate.
Prof Richard Mithen, from the Institute of Food Research in Norwich, who led the British and Italian team, said: "This is the first study providing experimental evidence obtained in humans that diets rich in cruciferous vegetables may reduce the risk of prostate cancer."
Dr Jodie Moffat, health information officer at Cancer Research UK, added: "Our best advice is to eat a healthy balanced diet that is high in all types of fruit and vegetables."
