The aim was to determine in what areas the thera-peutic application of soy predominates in clinical trials and to assess the emerging fields of its use by means of an analysis of bibliographic resources. A se-arch was performed in the MEDLINE database up to 31 december 2004, limited to the Title/Abstract field, and Clinical Trials as the type of publication. The abs-tracts from the publications selected (n=86) were re-viewed and different variables were assessed. A total of 3280 subjects were included: 15% men and 59% women (71% postmenopausal). The studies were per-formed basically in healthy individuals (71%). Twenty five percent of the studies investigated plasma levels of different metabolites and 21% determined hormo-ne or lipid profiles. After the year 2000 a new popula-tion focus was detected, with the publication of two studies in elite gymnasts and judoists, with positive re-sults.
The present observations indicate that soy sup-plementation in the competitive sports elite may be an emerging a application.
