Sulforaphane, a cancer-preventing compound found in broccoli, helps cells defend themselves for days against highly reactive and toxic molecules called oxidants. Unlike standard antioxidants that use the molecular equivalent of hand-to-hand combat, the sulforaphane works indirectly by enabling cells to create a diverse group of enzymes. These "phase 2" enzymes protect against cancer by blocking select chemicals from becoming carcinogens. Research shows that these enzymes have the ability to detoxify oxidants, which increases their value in disease prevention.
