Is it better to buy soup by the can – or by the box?

The next time you reach for your favorite can of soup on the supermarket shelf – see if it comes in a box instead...

 More manufacturers are starting to package their soup in boxes and it’s a really good idea. In a recent study, 90% of aluminum cans tested positive for BPA – a chemical linked to breast and other cancers. They even discovered some BPA in cans labeled “BPA free!” Soup in a box may cost a little more but is the next best thing to homemade.
