My New Goal (in light of the BPA everywhere)

So I now am on a mission, this might take a while to get down but I would like to work on making more things from scratch or buy fresh; specifically things that you might normally buy in a can like beans, canned fruit...that kind of thing. I'm looking up recipes and thinking my freezer will be getting tons of use since my canning jars have lids that contain BPA. I need to figure out how much BPA we are talking about with the canning jars though...I mean are we talking the same as the store shelf metal cans or are we talking more like a fifth of that? More research to come
