I was reading some studies that found bpa in a great variety of papers. It is scaring me. I already don't use unknown plastics, PVC and polycarbonate plastics. I don't eat anything from cans. Now I am thinking in I how can avoid paper. Those estrogens are everywhere ! And there is the soy. Soy protein is everywhere. I almost don't eat industrialized food anymore, just after checking the ingredients and being sure there is no soy protein there. There is estrogens in our industrialized milk, I don't drink milk too. Everythin was ok , but now that I know there is bpa in most papers I will have some big trouble thinking how to live without paper. And I am a engineer student, so it is hard to avoid paper.
