A variety of broccoli has been bred to contain higher levels of a compound called glucoraphanin.
This broccoli, called Beneforté, is now being grown commercially in the UK and around the world and is available in a number of supermarkets in the UK including Asda and M&S.
Beneforté was bred, using conventional techniques, by Professor Richard Mithen at the John Innes Centre, and Professor Mithen is continuing his work on broccoli by studying potential health benefits of the broccoli, and glucoraphanin, at the Institute of Food Research.
Research from human trials with 130 volunteers, and published earlier this year, showed that including this broccoli in the diet for 12 weeks reduced the levels of low-density lipoprotein cholesterol by an average of about 6%.
