Study Links Increased BPA Levels To Canned Soup Consumption
Regular consumption of canned foods contribute to higher levels of bisphenol A (BPA) in urine, a chemical compound that is usually associated with an increased risk of onset of hormone-dependent cancers, that include breast cancer and prostate cancer, according to a new study.
According to U.S. study – conducted by researchers at Harvard University and published in the Journal of the American Medical Association – people who consumed for five consecutive days canned soup had a urinaty value of bisphenol A, 1,200 times higher than peers that consumed fresh soup.
The study is presented as “one of the first to quantify the level of bisphenol A in humans after ingestion of food cans.”
It was already known that bisphenol A levels, increase in the body after drinking liquids which were long stored in certain plastic containers, according to Jenny Carwile coauthor of the study.
This particular study suggests that canned foods may be a more important matter of concern, especially in individuals that are using canned on a very large-scale.
Bisphenol A is a chemical compound present in large quantity in plastic products – its role is to make the plastic ’unbreakable’ - the plastic film lining the tins of canned drinks, and some dental amalgams, is associated with other substances considered ”endocrine disrupters”, increased risk for developing hormone-dependent cancers, especially breast and prostate.
The study involved 75 people who ate for five consecutive days canned soup and fresh soup without changing any other dietary habit. The analysis of the urine samples evidentiated after five days, a raise of the level of bisphenol A 1,200 above the normal value in consumers of canned soup.
But the risk was considered a temporary one, after bisphenol A was eliminated in urine. Researchers could not determine the amount of bisphenol A which still remains in the body after consumption of canned food, and larger regarding this matter would be necessary.
In France, the National Assembly adopted on 12 October, a measure prohibiting the use of bisphenol A in the manufacture of food containers from 2014 (2013 for food containers used by children under the age of three).
