Canned food, in most cases, has way too much salt—enough to send
any healthy person's blood pressure through the roof. But it may
not be the heavy salt content that makes canned food bad for
your heart. The can's lining contains a chemical that a new
study has linked to widespread kidney problems and
cardiovascular disease. The chemical in question, bisphenol A
(BPA), interferes with the way your body produces and regulates
estrogen, testosterone, and other hormones, including insulin,
which is why past studies have linked it to breast and prostate
cancers and to metabolic diseases like diabetes. The chemical
also promotes oxidative stress that can damage tissue, the new
study found, predisposing you to heart disease and kidney
problems. The New Scary Threat in Canned Soup The authors used
urine samples from 667 children ages 6 to 19 to compare levels
of BPA to levels of a protein called albumin; too much albumin
in the urine (albuminuria) indicates kidney problems and is
usually a precursor to cardiovascular
