Canned soups often contain relatively large amounts of BPA due to the way in which BPA in the plastic can liner migrates into the soup. Acid soups are thought to be particularly prone to this effect.
In the Harvard study (1) seventy five people were asked to consume home made soup for five days and then to have their urine tested for BPA; urinary BPA levels were low at 1.1 mcg/L after five days of home-made soups.
Similarly, urinary BPA was measured after five days of consuming canned soup once daily for lunch. The urinary levels of BPA rose an astonishing 20-fold to 20.8 mcg/L in the canned soup consumers after just five days. The canned soups consumed were five varieties of vegetarian Progresso brand including tomato and minestrone. Lead researcher Karin Michels, ScD, PhD, and colleagues reported that:
"The absolute urinary BPA concentrations observed following canned soup consumption are among the most extreme reported in a non-occupational setting."
Every single urine sample had high levels of BPA after canned soup consumption whereas 23% of the samples from home-made soup eaters were completely BPA-free. Other canned foods have also been found to contain high levels of BPA in other studies, canned pasta products such as ravioli, canned vegetables and beans are also at risk.
This study highlights the fact that when you are trying to conceive - or are pregnant - home-made food is the way to go; by rigorously avoiding canned foods you can keep a lot of BPA out of your diet and out of your baby.
