Eating lots of broccoli may slow down and even prevent osteoarthritis, UK researchers believe. The University of East Anglia team is starting human trials following on from successful lab studies.
Tests on cells and mice showed that a broccoli compound blocked a key destructive enzyme that damages cartilage.
They are asking 20 patients to eat a daily dose of broccoli. Our body takes this glucoraphanin compound and turns it into another, called sulforaphane, which appears to protect the joints.
The volunteers will have two weeks on the diet before going under the knife to have their badly arthritic knees repaired by surgeons. Rose Davidson and her team will look at the tissue that has been removed to see what impact, if any, the broccoli has had.
