Narrator:        This is Science Today. An anti-cancer compound found in broccoli, Brussels sprouts and other Brassica plants like cabbage and kale, has been found to lower the activity of an enzyme associated with rapidly advancing breast cancer. Study co-author, Leonard Bjeldanes of the University of California, Berkeley, previously discovered anti-cancer effects in mice, but says they're now moving along to conduct clinical trials in humans.

Bjeldanes:      We want to look at the specifics - what are the responses? How much of this material does it take to get the response and go at it from that point of view. Another interesting possibility is that the chemical may serve as an adjuvant for other kinds of immune therapies.

Narrator:        The best part is that the powerful chemicals come from a natural source. In fact, Bjeldanes says broccoli is truly a wonder food.

Bjeldanes:      If you think you can't eat broccoli - is that really how you're going to live your life? Everybody should be taking advantage of this wonderful plant in that way in the diet.
