Broccoli may help prevent osteoarthritis
Here’s a new reason to eat your vegetables: It may help you have healthier joints as you age. A new study, published in the journal Arthritis and Rheumatism, finds that a compound called sulforaphane can help fight osteoarthritis, the most common form of arthritis. And that compound is released when eating broccoli, brussel sprouts, cauliflower, kale, cabbage and bok choy.
The study, from the University of East Anglia, is significant in that it’s the first of its kind to demonstrate the relationship between sulforaphane and joint health. The goal of the study was to find out how much sulforaphane entered joints when vegetables were consumed and what effect they would have.
Researchers performed a relatively small trial, about which lead researcher Ian Clark, professor of musculoskeletal biology at UEA, said, “The results from this study are very promising. We have shown that this works in the three laboratory models we have tried, in cartilage cells, tissue and mice.”
UEA researchers are planning another trial, this time in 40 osteoarthritis patients who are due to have joint replacement surgery. Half of the patients will be fed “super broccoli,” with extra sulforaphane, two weeks before surgery. Researchers will compare patients post-surgery to see if they can detect sulforaphane in the replaced joints and whether it affected joint metabolism.
