xenoestrogens and muscle mass

[sin]

so, i'm sitting here studying for my endocrinology exam and something hits me. estrone (from high levels of testosterone or conversion of androsteindione) mediates the actions of xenoestrogens [eg. from tofu etc] by activating the ERbeta receptors in the sertoli cells of the testes. the result of this is endocrine disruption (xenoestrogens are called estrogenic endocrine disruptors) and a drop in natural testosterone production and function.
so, after all that my question is: does anyone know of any good studies with xenoestrogens, or more importantly, a good list of foods to avoid while on steroids or andro. or secondly a way to block xenoestrogens with an antagonist.
any input would be much appreciated.

The big source of xenoestrogens I know of is any food in plastic containers. Most plastic products contain bisphenol-A, which is an estrogenic chemical.

Anytime you eat or drink anything that has been exposed to heat in a plastic container you are getting a hefty dose of xenoestrogen.

Longhorn Dr., does that include Tupperware? Not the throw away kind, but the reusable ones. How much is a "healthy dose" and would this actually have an affect on you if you were taking aas? Interesting.
