Dietary Soy Reduces Colon Carcinogenesis in Human and Rats

The anti-cancer activity of individual soy phytochemicals (non-nutritive plant components with biological activity) have been extensively studied in vitro and in vivo. There is much less data relating soy consumption and colon cancer. This chapter will summarize epidemiologic studies and discuss the animal experiments and one intervention study that have evaluated the potential of dietary soy to inhibit colon carcinogenesis.
