Chemical in broccoli blocks growth of prostate cancer cells

Those seeking yet another reason to eat their veggies, take note. Researchers at the University of California, Berkeley, have found that a chemical produced when digesting such greens as broccoli and kale can stifle the growth of human prostate cancer cells. The findings show that 3,3′-diindolylmethane (DIM), which is obtained by eating cruciferous vegetables in the Brassica genus, acts as a powerful anti-androgen that inhibits the proliferation of human prostate cancer cells in culture tests.
