Canned soup and drinks can dramatically increase the level of a dangerous chemical in the body. Just one serving of soup, for instance, raises the amount of the chemical, bisphenol A (BPA), twenty fold.
A research team from Harvard School of Public Health, were shocked by the amount that BPA increased in the body, even after eating one serving of soup. The levels are “among the most extreme reported in a non-occupational setting”, say the researchers, led by Dr Jenny Carwile.
The cans increased BPA levels by a far greater extent than happens when drinking from a plastic container. BPA has already been banned from baby drinking bottles, and the Harvard researchers are calling on can manufacturers to eliminate the chemical from their products, too.
Although BPA is a dangerous chemical, the researchers do not know what the health implications may be from consuming canned foods and beverages, but they advise people to reduce the amount they use, especially if they are currently doing so every day.
