A new study of people who ate one serving of canned food daily over the course of five days, the study found, had significantly elevated levels — more than a tenfold increase — of bisphenol-A, or BPA, a substance that lines most food and drink cans.
The new study, which was published last month in The Journal of the American Medical Association, is the first to measure the amounts that are ingested when people eat food that comes directly out of a can, in this case soup. The spike in BPA levels that the researchers recorded is one of the highest seen in any study.

The circulation changes continued after other symptoms had subsided, which researchers said may mean that some children are returning to sports while they are still vulnerable to reinjury.
