interesting; might help explain a fluidic gender / transgender
  issues. Copper leads to estrogen, found in coffee/cocoa, zinc
  leads to testosterone, found in pumpkin seeds and many other
  foods and drinks and environment.... quite possible a lot of
  chocolate during pregnancy could lead to men who feel like a
  women trapped in a man's body... *although* _apparently_
  hormonal levels don't correspond to transgender psychologies as
  once suspected.... or maybe they do. I pulled the last sentence
  out of my butt ,but the rest of it is plausible.
