Eating food that comes out of a can significantly raise the level of bisphenol-A, or BPA, detected in a person’s urine, according to research published in the Journal of the American Medical Association.

BPA, an endocrine disruptor, has been linked to infertility, higher risks of breast and prostate cancers, heart disease, diabetes and obesity.

In recent years, it was widely found in plastic containers and baby bottles but many manufacturers have stopped using it in their products. Today, BPA is found in the lining of many food and soda cans.

For their study, researchers followed a group of volunteers who ate canned soup for five consecutive days and then homemade soup for another five days. Another group did the same thing but ate homemade soup first and then canned soup. All of the participants gave urine samples after eating one kind of soup for five days.

The results showed that after eating canned soup, the level of BPA rose from about 2 micrograms per liter to 20 micrograms per liter.
