A study by researchers at the Harvard School of Public Health indicates that BPA used in the lining of food cans is absorbed by the food and then ingested by consumers.
The experiment involved 75 participants, half of whom ate a lunch of canned vegetable soup for five days, followed by five days of fresh soup; the other half did the same experiment in reverse order. “The analysis revealed that when participants ate the canned soup they experienced more than a 1,000 percent increase in their urinary concentrations of BPA, compared to when they dined on fresh soup.
“In general, most studies have found that urinary BPA levels in typical adults average somewhere around 2 micrograms per liter. That was roughly the levels the Harvard researchers found in the subjects after a week of eating the soup made from fresh ingredients. After eating the canned soup, though, their levels rose above 20 micrograms per liter, a 1,221 percent increase.”
Ian: Dammit! I haven’t had canned soup for many years but I do love some tuna with my green salad at lunch….
