Cruciferous Vegetables

For a long time scientists have known that the consumption of cruciferous vegetables (broccoli, radishes, cabbage, cauliflower, and others) is associated with a marked reduction in the incidence of numerous forms of cancer. The reason this happens is that these vegetables contain substances that fight cancer in a number of different ways. Some of these substances are known as indoles. Researchers have stated: "The natural indoles 3,3'-diindolylmethane (DIM), ascorbigen (ASG), indole-3-carbinol (I3C), and indolo[3,2-b]carbazole (ICZ), as well as the natural isothiocyanates sulforaphane (SUL), benzyl isothiocyanate (BITC) and phenethyl isothiocyanate (PEITC), all possess cancer chemopreventive properties. It is now shown that DIM, ICZ, SUL, and BITC can each stimulate apoptosis in human colon adenocarcinoma LS-174 and Caco-2 cells. . . . Together, these phytochemicals may prevent colon tumorigenesis by both stimulating apoptosis and enhancing intracellular defenses against genotoxic agents."1 [Emphasis supplied.] The gist of this research is that indoles can prevent cancer. They do this by inhibiting tumor formation. More about the lovely cruciferous family in later posts. In your comments, please tell me whether you eat any cruciferous vegetables.
