In a new study of "Soy isoflavones and cognitive function." by , , in The Journal of nutritional biochemistry (2005) Volume: 16, Issue: 11, Pages: 641-649ovariectomized female rats were fed a diet high in soy isoflavones for 10 months. researchers found that in abstract although data from humans, cultures, and animal models are currently insufficient for elucidating the metabolism of soy isoflavone actions on cognitive function and the nervous system, we suggest two putative pathways; (1) an estrogen receptor-mediated pathway and (2) via the inhibition of tyrosine kinase, in particular by genistein, which is one of the soy isoflavones. Although soy isoflavones appear to have a positive effect on brain function, further research is needed to determine not only the efficacy but also the safety of soy isoflavones on the nervous system and cognitive function.
