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. We’ve known for a while that drinking beverages that have been stored in certain hard plastics can increase the BPA levels in your body. This study suggests that canned foods may be an even greater concern, especially given their wide use.
Canned Soup Consumption Associated With Increased BPA Levels
Exposure to the endocrine-disrupting chemical BPA, used in the lining of metal food and beverage cans, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease, diabetes, and obesity in humans. In addition to the lining of food and beverage cans, BPA is also found in polycarbonate bottles (identified by the recycling number 7) and dentistry composites and sealants.
The researchers set out to quantify whether canned-soup consumption would increase urinary BPA levels relative to eating fresh soup.
They recruited two groups of volunteers. One group consumed a 12-ounce serving of vegetarian canned soup each day for five days; another group consumed 12 ounces of vegetarian fresh soup (prepared without canned ingredients) daily for five days. After a two-day “washout” period, the groups reversed their assignments.
Urine samples of the 75 volunteers taken during the testing showed that consumption of a serving of canned soup daily was associated with a 1,221% increase in BPA levels compared to levels in urine collected after consumption of fresh soup.
The researchers note that the elevation in urinary BPA levels may be temporary and that further research is needed to quantify its duration.
The magnitude of the rise in urinary BPA levels that were observed after just one serving of soup was unexpected and may be of concern among individuals who regularly consume foods from cans or drink several canned beverages daily.
