One other thing that is important as a food element negatively impacting testosterone, among many other things, is to avoid anything soy related (except perhaps a little bit of organic fermented version). This is more difficult than initially thought since it is used in so much these days as cheap, mostly GMO, filler/protein/lecithin/texturing and the oil most restaurants use these days. Not sure how much you have read on the Primal/Paleo lifestyle, but there are great books and sites with info on this that also help with reducing insults to the body and supporting testosterone production naturally.
