Study Links Canned Soup to Increased BPA Levels Eating canned
soup may increase consumers’ levels of a chemical linked to
obesity and cancer, according to a study published last week by
scientists at the Harvard School of Public Health in the Journal
of the American Medical Association. Prior research has linked
the substance, bisphenol A (BPA), to weight problems,
neurobehavioral deficits in children, and increased risk of
breast and prostate cancer. Results of the HSPH study showed
that volunteers who consumed a 12-ounce portion of vegetarian
canned soup daily for five days experienced over a thousand
percent increase in urinary BPA concentration compared to
volunteers who ate fresh vegetarian soup. Jenny L. Carwile—a
doctoral student in epidemiology at HSPH and lead author of the
study—said she was not expecting such drastic results. “The
increase in BPA was surprising because we gave the candidates
just one 12-ounce serving of soup per day,” Carwile said.
Carwile previously conducted a study on consumptio
