Bisphenol A, or BPA, is a compound that can disrupt your hormones, as it can mimic estrogen. As a synthetic compound, however, it is more readily absorbed than natural hormones. BPA has been linked to a number of health conditions, including obesity, cancer, sexual dysfunction, reproductive issues, diabetes and heart disease. People first started hearing about BPA in plastic bottles and other plastic containers, but now it has been found in canned goods as well, including canned soups.
A recent study found that people everyone who ate canned soup had increased levels of BPA in their urine compared to those who ate fresh soup. It appears that BPA from canned goods like soup may actually be more of an issue than BPA from plastic, so eliminating your use of plastic goods that contain BPA may not be enough. You may want to limit your use of canned goods, including sodas and other canned beverages, or search out the manufacturers that do not use BPA in the linings of their cans. These can be hard to find, however. BPA levels can increase as much as ten times if you consume one serving per day of any type of canned goods for five days if the cans are lined with BPA. Many people eat multiple servings of foods from cans each day, thus increasing the potential risk to their health even further.
Further research is needed, however, to figure out whether the increases in BPA levels after eating canned goods are only temporary, and to verify whether and how much these increases may affect your health. The U.S. Food and Drug Administration is looking into the safety of BPA due to the recent studies that have shown the potential dangers of this chemical, and has admitted that it may not be safe, especially in the case of children.
BPA is also found on the paper that is used to print receipts, dental sealants, and some plastics labeled with a 3 or a 7 recycling code. It may be difficult to eliminate all exposure to BPA, but it may be a good idea to try to limit it as much as you can. Consider using frozen food instead of canned food, and storing foods in glass or ceramic containers instead of plastic storage containers. If enough people show their concern about the presence of BPA in their canned goods more manufacturers will use alternatives to BPA in the linings of their metal cans.
