Washington: Consuming canned soups instead of fresh ones raises bisphenol A (BPA) concentrations in urine, a new study has suggested.The study conducted by researchers at the Harvard School of Public Health (HSPH) found that a group of volunteers who consumed a serving of canned soup each day for five days had a more than 1,000 percent increase in urinary bisphenol A (BPA) concentrations compared with when the same individuals consumed fresh soup daily for five days.“Previous studies have linked elevated BPA levels with adverse health effects. The next step was to figure out how people are getting exposed to BPA,” said Jenny Carwile, lead author of the study.“We’ve known for a while that drinking beverages that have been stored in certain hard plastics can increase the amount of BPA in your body.”“This study suggests that canned foods may be an even greater concern, especially given their wide use.”Exposure to the endocrine-disrupting chemical BPA, used in the lining of metal food and beverage cans, has been linked with cardiovascular disease, diabetes, and obesity in humans.The researchers, led by Carwile and Karin Michels, associate professor in the Department of Epidemiology, set out to quantify whether canned-soup consumption would increase urinary BPA concentrations relative to eating fresh soup.
