Bisphenol A, also known as BPA, is found in many canned foods. It is a byproduct of the chemicals used to prevent corrosion.We've blogged in the past about how higher Biphenol A exposure during pregnancy can adversely affect toddlers.
Unfortunately, there is more bad news surrounding BPA. A study published yesterday online in the Journal of the American Medical Association examined urine samples collected from a group of participants who ate 12 ounces of fresh soup every day at lunchtime for five days, versus another group that ate the same amount of canned soup each day for the five-day period.
The results found that the people who the canned soup every day for five days had BPA levels of 20.8 micrograms per liter of urine, whereas people who ate fresh soup had BPA levels of 1.1 micrograms per liter.
Researchers were astounded by the numbers calling the levels of BPA seen in the study participants eating canned soup as "among the most extreme reported in a nonoccupational setting." (in the general population, BPA levels have been found to be around 1 to 2 micrograms per liter). Previously, concerns had focused on BPA leaching from certain plastics into food. But apparently, BPA from cans may be of even greater concern.
Tying this news to our earlier BPA post referenced above, clearly pregnant women should avoid canned foods during their pregnancies.
