The more and more I think and write about food, the more I put my pantry shelves to scrutiny.

If you are not lucky enough to have jars of preserved tomatoes from your summer garden harvest, the BPA in the cans lining could be doing damage. But what is BPA? What are the healthy and environmental concerns?
