An inverse correlation between thyroid cancer risk and phytoestrogens was recently proposed as a result of a multi-ethnic population-based case control study conducted in the San Francisco Bay Area (Hom-Ross et al., 2002). In this study, dietary habits and phytoestrogen consumption were assessed by a food-frequency questionnaire and by a nutrient database. The outcome of the study was that soy-based foods and alfalfa sprouts were associated with a reduction of thyroid cancer risk, whereas a Western diet did not influence cancer risk. No difference was observed between American and Asian women or between pre- and postmenopausal women. Furthermore, among the few compounds examined, the isoflavones genistein and daidzein and the lignan secoisolariciresinol were the phytoestrogens most frequently associated with risk reduction (Horn-Ross et al., 2002). 

To obtain an updated set of data on the phytoestrogens content in foods and diets, we suggest checking the following websites http //www.venus-ca.org/database.htm (phytoestrogen database of the EU-funded project VENUS) http //www.nal.usda.gov/fhic/foodcomp/Data/isoflav/isoflav.html (USDA-Iowa State University database on the isoflavones content of foods) and http //www.ilf.bbsrc.ac.uk/phytochemicals/Links.htm (Institute of Food Research Database on the levels of bioactive compounds in plant foods).

A commercial database covers cinnamates, flavonoids, isoflavones, and lignans plus many nonphenolic plant constituents. Chapter 4 in this volume describes the development of a UK-focused database covering primarily anthocyanidins, flavanols, flavanones, flavones, and flavonols.
