January 29/Champaign, Ill./The Express -- Eating broccoli with mustard can boost the vegetable's cancer-fighting ability, scientists have found, and adding radishes, rocket or wasabi, a form of Japanese horseradish, can have the same effect.
However, overcooking the broccoli can kill the vital enzyme it contains. Steaming it quickly for just two to four minutes is the best way to preserve its well-known health benefits, say U.S. scientists.
