Soup Can be a Great Food, as Long as it is not Canned
A Harvard study showed that patients who ate soup from a can had 1221% higher levels of BPA (biphenol A) than those who ate home-made. This is an important toxin that can mess with your immune system and your endocrine glands. Even organic soup from a can contains high levels of BPA. Thanks to Robert Rowen, who pointed this out, based on a November 2011 study from JAMA.
